The utility model has the advantages that：

1）The utility model is easy to operate：

Existing keeper or world latch are all above to push away or lower pulling-pushing rod could complete the stretching or contracting of world pin lock point Return, even if it is also that after a button is pressed be over inward, must rotate or increase other actions to improve to some extent, even if or It is possible to utility model the lock point of world latch can be retracted by entering, but can not achieve and the lock point of world latch is stretched The function of going out, the utility model compensate for the deficiency of this respect function completely, and one lower button of flicking can complete lock point retraction and open The function that door or lock point are stretched out and locked a door.

The utility model only needs one lower button of flicking that just keeper or pin lock point can be stretched out so as on door lock at once, and When opening the door, in this button of same flicking once can also check and accept the lock of keeper latch that bride visits her parents with her husband for the first time after the wedding at once fan, so that door is opened.Cause This, the stretching locked a little need to only be performed with retracting by same mode of operation, as soon as flicking lower button can be completed, this is effectively solved The door-opening mode of keeper latch is changed into most simple and more directly, is more convenient child old man and uses.

2）The one-touch point of the utility model starts Telescopic mode and greatly improves the speed opened the door and locked a door：This The characteristics of internal structure for being due to the utility model, determines that the structure of the utility model is that one-touch button runs through not first The steel that becomes rusty protects lock panel and lock body shell side, and positioning is limited in sleeve, rotation under then pushing down compression bar arm to the right, and compression bar arm Lateral pin nail in tail end U-type groove is held in the mouth in the small U-shaped mouth of the oscillating rod, compression bar arm is due to being to surround the rotation of its own Axial right rotation, therefore compression bar arm tail end can drive the oscillating rod front end to turn to anticlockwise, the tail end of oscillating rod and transmission Bend arm is connected and is driven bend arm and is fixed in lock housing and can only be rotated around the fixing axle of itself, and before oscillating rod Portion is to anticlockwise, therefore the tail end of oscillating rod will drive bend arm to the rotation of bottom right both direction and movement.Again because of the biography Dynamic bend arm is connected with the transmission both arms and the both arms that are driven are connected and described with the transmission U-type groove Transmission U-type groove is right be fixed together with the actuator push rod therefore rotary force from bend arm to bottom right and what is moved right push away Power can promote transmission both arms, transmission U-type groove also to move and rotate to the right successively.Due to being mounted so as to below transmission U-type groove Can free rolling power-assisted scroll wheel, and this scroll wheel is limited on lock body lower end inner wall and rolls, therefore has passed to biography Dynamic U-type groove is also blocked by force to the power of bottom right by this lock body lower end inner wall, thus rotary force downward before will be forced Change direction, be superimposed with the power to move right and promote actuator push rod to move right.Due to actuator push rod again with rotation Main force's sliding piece of Force system is against contact.Since actuator push rod promotes to the right, main force's sliding piece will be promoted to upper right Rotate in an anti-clockwise direction.Main force's sliding piece promotes the core part of the utility model by small group of nail（Cross gear）On height Low fan disk counterclockwise rotates, and fan driver plate is connected with cross gear, promotes cross gear to rotate counterclockwise So that cross gear rotates a certain angle, and cross gear is contacted with driven pinion intermeshing, due to The rotation of cross gear has also driven the pinion gear being fixed on pinion gear seat also and then to rotate, and pinion stand and overcoat bullet The gearing telescopic rod connection of spring is fixed, will also be there occurs since pinion gear is not only driven outside rotation rotation by cross gear The movement of position, so that the gearing telescopic rod of outer casing spring（Hereinafter referred to as interlock telescopic rod）Stretched out or what is bounced back shows As it is achieved thereby that so-called one-touch button point starts the function of stretching with contracting.

The rotating fulcrum of compression bar arm of the utility model is almost the far pressure spot from this pressure arm, this is to use The principle of lever, in addition the lower end of the utility model transmission U-type groove 20 can freely roll equipped with live bearing, the mesh so designed Also for the frictional force greatly reduced between part, these comprehensive structural principles so that the utility model practicality is got up both It is laborsaving, and save trouble.So as to substantially increase the speed opened the door and locked a door.

3）The keeper lock tongue of automatic telescopic function that the middle control pin lock of one-touch button switch can just be completed or latch Tool locks performance requirement, not only improves the speed of enabling, and flexible function can just be automated without electronic components by also realizing so that The middle control of keeper, latch is changed into more directly, and operation is simpler, not only facilitates child old man to use, and also achieves secondary in an industry Function of the door world latch door Telescopic without electronically controlled mechanical automation lock and unlock.

4）The cost of raw material greatly reduces in the utility model：Many lock bodies are to realizing automatic telescopic work(at present Can, would have to add electronic system and power supply.Want to meet under the stretching of keeper latch and contractile function perfect, nothing High-tech electronic system is set to control in needing, and is entirely the system of mechanical structure with regard to that can complete keeper or world pin lock point Stretch out or retract, and the utility model compensate for the deficiency of this respect function completely, one lower button of flicking can complete to open the door or Close the door, so that the cost of raw material greatly reduce.

5）The utility model provides multinomial using selection for user：

Controlled in existing world latch in structure, the two poles of the earth component up and down being connected with world pull rod, otherwise it is hook form , otherwise be screw sheel form, designer for user more consideration is given to, be that coupling type is just forever coupling type, It is that screw-sleeve is just forever screw-sleeve, cannot just allows user to have a selection, and this can really allow user with new There is multinomial selection.

Due to middle control pin lock the structure type of the one-touch button switch in itself, upper and lower two gearing telescopic rods One end be tapped with thread and be exposed at outside lock housing, telescopic rod outer end thread can connect the part of coupling type, can also connector sleeve Part of the cartridge type with internal screw thread, therefore this structure just provides multinomial selection for user, but coupling type with it is telescopic not Need to exist at the same time, if but only selected first, one, the connecting rod of the world latch of user according to both needs of user It is to carry flat square hole type, user can select the part of the utility model coupling type to be assembled, if user One, the connecting rod of keeper world latch is the connecting rod for attacking threaded, and user selects the utility model sleeve nut formula part to carry out Assembling, and the utility model can also especially meet the world latch structure of the linear dragline type of following steel wire, therefore, the utility model The selection of multinomial property is not only provided for user, but also has saved unnecessary cost for user and has wasted.

6）The utility model has expanded its use scope：

Since the outer end head of two telescopic rods up and down of the utility model is tapped with thread, an auxiliary lock body of the utility model Upper and lower ends respectively have such telescopic rod, and are attached thereto the coupling type of the two poles of the earth up and down of assembling in the future or lengthen screw cap type zero Part, is all to tighten to be connected with the telescopic rod of the utility model by thread, since this assembling mode is easy to disassemble, works as use As long as person lays down the stainless steel shield lock panel of the utility model in advance, the two poles of the earth hook or telescopic one up and down is then laid down again Only, as long as the rational position of the shop front opens an aperture indoors, make the one-touch button of the utility model exposed from this eyelet On door, then the utility model is transversely mounted and is fixed in door leaf, such use just makes world latch can be changed to horizontal To keeper use.Therefore the utility model is not only used frequently as the middle control of world latch, is so transversely mounted and is also opened up The scope that it is used is opened up, so as to more be liked by people.

Embodiment

In order to which the technological means, technical characteristic, purpose of utility model and the technique effect that realize the utility model are easy to bright It is white to understand, with reference to being specifically illustrating, the utility model is expanded on further.

It is a kind of middle control pin lock of the one-touch button switch of band in the utility model such as Fig. 1 to Fig. 5, including a shell Body, the housing lock shell 1, preceding lock shell 2 and stainless steel shield lock panel 3 after including.

The utility model further includes the pressure drive mechanism 100 being placed in housing, rotational force mechanism 200 and contractility Transmission mechanism 300.The pressure drive mechanism 100 in the utility model is rotatably arranged on the side in the housing, institute State rotational force mechanism 200 rotatably be arranged on the pressure drive mechanism 100 inner side, and with the pressure drive mechanism 100 touch contact.The flexible force transmission mechanism 300 is contacted with the rotational force mechanism 200 by gear intermeshing Connect, and expanding-contracting action up and down is realized under the drive of the rotational force mechanism 200.

Pressure drive mechanism 100, rotational force mechanism 200 and flexible force transmission mechanism 300 in the utility model have The structure of body, and mutual action matching relationship are as follows.

Pressure drive mechanism 100 in the utility model is primarily to realize the transmission of pressure, mechanism is in conveying capacity The combination of these structures in power can not only be spread out of, and can also be laborsaving, and the stroke of initial pressure can be saved, specific knot Structure is as follows：

With reference to figure 6 and Fig. 7：Pressure drive mechanism 100 in the utility model includes such as lower component：One-touch button 4, press Button sheath 5, button are spacing 6, button spring 7, U-shaped compression bar arm 8, compression bar arm rotation fixing axle and nut 9, the first compression bar arm reset Spring 10, compression bar arm spring fixing pin 11, oscillating rod 12, oscillating rod spring 13, oscillating rod spacer pin 14, transmission bend arm 15, Oscillating rod and bend arm connecting shaft and nut 16, bend arm rotated locating shaft and nut 17, transmission both arms 18, bend arm and both arms Connecting shaft and nut 19, transmission U-type groove 20, both arms and U-type groove connecting shaft and nut 21, power-assisted scroll wheel 22, scroll wheel position Nail 23, actuator push rod 24 and push rod spring 25.

When finger, which presses to the right button 4, stretches to 5 millimeters deep, button 4 pushes down lever-type U-shaped compression bar arm 8 at once, Power is transmitted to oscillating rod 12.Because oscillating rod 12 is controlled by the oscillating rod spacer pin 14 of the U-shaped tiger's jaw of compression bar arm, when U-shaped compression bar When arm 8 revolves to the right clockwise so that 12 upper end of oscillating rod is swung to the left, lower end is swung to the right.Oscillating rod 12 is not only controlled by U-shaped Compression bar arm 8, is also controlled by transmission bend arm 15.

Because oscillating rod 12 is fixedly connected by rotation axis and nut 16 with transmission bend arm 15, due to the afterbody of oscillating rod With transmission bend arm by rotating axis connection, at this moment when the counter-clockwise swing of oscillating rod 12, the front portion of oscillating rod is to left swing It is dynamic, and the afterbody of oscillating rod is to swing to the right on the contrary so that transmission bend arm 15 is forced to surround 17 up time of locating shaft of itself Pin rotates, due to the rotation of bend arm 15, cause to be driven both arms 18 also follow move right and produce the thrust that moves right and The rotary force moved downward.

In addition, transmission both arms 18 are fixedly connected with transmission U-type groove 20 by axis and nut 21 again, and the lower end of U-type groove 20 Assemble must have can free rolling power-assisted scroll wheel 22, the power-assisted scroll wheel 22 directly with it is rear lock shell 1 inner wall contact, that is, help Lock shell 1 cannot be moved down after power scroll wheel 22 is limited to, and the movement that can only turn right, scroll wheel can produce when being extruded with lock housing wall Raw very big pressure and frictional force, the scroll wheel 22 installed in U-type groove 20 is then can be with free rolling roller, because before this The power moved downward that face produces is forced to change direction, so as to be superimposed to form consistent fortune of turning right with the thrust for movement of turning right Dynamic thrust.When bend arm 15 resets rotation counterclockwise, at this time since no pressure acts on, bend arm 15,18 and of transmission both arms The distance of associated nodes will mutually be drawn close at transmission U-type groove 20 3.

Bend arm 15 is when rotating clockwise, at this time due to having pressure effect, bend arm 15, transmission both arms 18 and transmission U The distance of associated nodes will turn right as the arm of people and stretch expansion at type groove 20 3, and being particularly driven both arms 18 can approach Level is stretched to the right, and since transmission U-type groove 20 is connected fixation with actuator push rod 24, and then actuator push rod 24 also pushes away to the right It is dynamic, so press 5 millimeters of stroke depth calculation to the right from initial button 4, the fortune of stretching, extension to the right of each parts more than It is dynamic, as a result so that the movement travel distance of actuator push rod 24 can at double growth so that reached press lightly on button 4 just can be completely Foot moves required stroke distances below.

Material is thus formed the process that whole first class pressure system promotes to the right.Above-mentioned action is exactly robot's bending With stretching function.Belong to extended configuration when belonging to the state of natural shrinking when no pressure, and having pressure promotion.The Telescopic The advantages of be to obtain several times of stroke distances after being conveyed step by step with minimum beginning key stroke, meet small stroke and obtain big row The harvest of journey.

The conveying that the button 4 of the utility model presses part body power before U-shaped compression bar arm 8 is to utilize lever principle, compression bar Arm is longer, more remote more laborsaving apart from fulcrum rotation axis 9.

The structure for the oscillating rod that mechanism uses so that active force changes from small to big, then from large to small, so as to reach labour-saving Function.

In the utility model when U-shaped compression bar arm 8 turns right swing, and opposite opposite direction is then followed to the left in 12 upper end of oscillating rod Swing.Otherwise when U-shaped compression bar arm 8 turns left swing reset, 12 upper end of oscillating rod, which then resets to the right, to be swung.Its operation principle be by Determined in the structure and connection relation of U-shaped compression bar arm 8 and oscillating rod 12.

First, there is a spacer pin being transverse on U-shaped tiger's jaw 14 in the side surface direction of the U-shaped tiger's jaw of compression bar arm 8, and The effect one of this spacer pin 14 is the swing of forced oscillation bar 12, because the small U-shaped mouth of 12 upper end of oscillating rod just holds in the mouth this A spacer pin 14.12 outside diameter of oscillating rod is equipped with one with adjustable spring 13.And 12 lower end of oscillating rod by connecting shaft 16 and nut with Bend arm 15 connects, be positioned axis 17 and nut be fixed on after lock on shell 1 and preceding lock shell 2, but they can only surround this Bend arm rotated locating shaft 17 swings, and cannot be subjected to displacement.

Secondly, it is to be determined by the position relationship of each component, when the company of the fulcrum shaft 9 of compression bar arm, oscillating rod and bend arm Adjustable spring 13 is at this time by the pressure of pin 14 in place when spindle 16, bend arm rotated locating shaft 17 are rotated on same straight line Maximum.As long as external force at this time a little is remake under use, oscillating rod 12 at any time all can towards or left or right direction swing, directly It can just stop to its limit point is swung to.Therefore since oscillating rod 12 and button are respectively distributed to compression bar arm rotation axis 9 Both ends, therefore their direction of motion is opposite.

When external force presses moulded rod arm 9 to the right, due to the principle of lever, oscillating rod 12 is limited pin 14 and is put to anticlockwise It is dynamic.Therefore the fulcrum shaft 9 when compression bar arm, 17 3 points of connecting shaft 16, the bend arm rotated locating shaft of oscillating rod 12 and bend arm 15 The required external force action of pressure when being closely located to collinear will start to diminish.

Therefore, when the firm contact button 4 of external force and to start to apply pressure of active force when on button 4 be to change from small to big, when External force effect is lower so that during above-mentioned described three point on a straight line, and the external force that this structure needs will from large to small, so as to reach laborsaving Function.

With reference to shown in figure 8 and Fig. 9, the rotational force mechanism 200 in the utility model includes such as lower component：First L-type The two-way guide plate 27 of two-way guide plate 26, the second L-type, main force's sliding piece bracket 28, main force's sliding piece rotation axis and nut 29, master It is power sliding piece 30, main force's sliding piece spring hangering nail 31, main force's sliding piece resetting spring 32, resetting spring fixed pin 33, round small Dial nail 34, cross driving gear rotation fixing axle 35, cross gear position limiting base 36, cross gear position limiting nail 37, limit Position langrage spring 38, base locating pin 39, and cross gear 40.

The most crucial parts of rotational force mechanism 200 in the utility model are actively cross gear 40, are passed through The appearance structure of the cross gear 40 can realize the required function of the utility model.

The appearance of cross gear 40 in the utility model is deeper by four longer cross peak positions and four Paddy position is formed, and just needs 45 degree of rotation standard can be only achieved when paddy position rotates to peak position, and peak position only in this way Identical, it could be the important bar that the utility model has established feasibility that the consistent shaped member in paddy position, which is constantly alternately rotated 45 degree of angles, Part and feature.

Pause once to allow it accurately to rotate 45 degree with external force, that is, complete once completely to close the door or lock a door to need Will.In addition to this cross 40 main appearance structure of gear is cross, its positive concentric ring type face has been divided into 8 in equal size The consistent fan slope Interphase interval equal distribution of the identical structure of group shape.When the high-order side of the structure rotates to alternate low level When side or face, just also have rotated 45 degree, thus the alternate rotating angle of distribution of this step just with this active cross The rotating angle of 40 main body of type gear is coincide.

Therefore the Facad structure of the cross gear 40 of active of the utility model is exactly such sector structure.Then more than First class pressure transmission mechanism 100, when last actuator push rod 24 promotes to the right so that main force's sliding piece 30 is around its top itself The upper rotation counterclockwise to the right of rotation axis 29.Because actuator push rod 24 is that shake-up property contacts with main force sliding piece 30, when transmission pushes away When bar 24 promotes to the right, main force's sliding piece 30 will surround the upper rotation counterclockwise to the right of its top rotation axis 29 of itself.

30 top reverse side of main force's sliding piece, which assembles, must small group of nail 34 of a circle, and circular 34 end faces of small group of nail Contact with the bottom surface step in the core component of the utility model actively cross positive fan face of gear 40, small group follow closely 34 circle Cylinder is abutted due to the vertical plane 4032 of fan.When main force's sliding piece 30 under the effect of external force, to the right during upper rotation counterclockwise, This circular small group of nail 34 will be driven also to be rotated counterclockwise to upper right side, thus circular small group of nail 34 can also stir this master by force The step upper rotation counterclockwise to the right in the fan face of cross gear 40 is moved, so as to reach whole cross 40 rotating mesh of gear 's.

And rotating angle is constrained be subject to other outer points of force application, necessarily pause when 45 degree of angles are rotated to Once, that is, complete paddy position is completed once with the position between peak position to replace.Replace when completing current complete paddy peak position The main force's sliding piece 30 and small group of circle that the external force of function is stirred follow closely 34 and the spring 32 that can be reset retracts in situ wait next time Stir.

And the external force effect part of the rotation angle of cross gear 40 is limited then at the back side of this cross gear 40, Contacted with the limit hole of cross gear 40.When cross gear 40 is forced to rotate to 45 degree of angles, in back side limiting plate 36 Banking pin 37, under the action of banking pin spring 38, be just intermeshed with the location hole at cross 40 back side of gear.Therefore It is deadlocked by force when forcing cross gear 40 to rotate to 45 degree of angles.Complete whole two level rotational force above Rotary movement of mechanism.

The one side of cross gear 40 with rounded corners has the sector structure of height separately in the utility model, and described Fan be that eight groups of alternate height are divided equally, every group is 45 degree of angle with center, and every group all surrounds center between fan and fan Point height is distributed, and the contour plane in bottom surface position, and high face is inclined-plane, and minimum bevel edge is overlapped with bottom surface side.

The opposite side of the cross gear with rounded corners has a round boss, and boss face has several ball-type grooves. The cross gear with rounded corners is divided into four peak positions and the structure of four paddy position compositions, and the position of peak position is anodontia rounding Type structure, and paddy position be male type and with structure that the body of this cross gear is isocentric circular arc.

With reference to figures 10 to Figure 16, the 40 specific structure of cross gear in the utility model is：

Four gear arms 402 of 401 periphery of gear are arranged in including a gear 401 and equidistantly, should The structure of four gear arms 402 is identical, and four gear arms 402 are an integral molding structure with the gear 401.

A toothrow 405 is arranged with along the center line both sides of each gear arm 402；Each gear arm 402 Top is gear peak position 406, is gear paddy position 407 between adjacent two gear arm 402.The gear peak position 406 and the tooth It is the cambered surface concentric with the axis hole 4011 to take turns paddy position 407.

The sector structure 403 in the present embodiment is eight groups, the sector structure 403 include inclined-plane 4031 and with institute State the vertical plane 4032 that inclined-plane 4031 connects.Every group of sector structure 403 is with the center of gear 401 into 45 degree of angle.

Inclined-plane 4031 in every group of sector structure 403 and the bottom surface 4033 of gear in the present embodiment surround gear 401 center of body height is distributed, and the bottom surface 4033 is contour plane, and the chamfered edge on the inclined-plane 4031 is low with bottom surface 4033 Side overlaps.

If Figure 11 is another sector structure in the utility model, the sector structure and the sector structure institute in Figure 10 Play the role of it is identical, in structure both slightly different, i.e., between multiple inclined-planes 4031 around gear center, mutually Linking distribution, makes the flash on the low side inclined-plane adjacent thereto of adjacent bevel surfaces connect, i.e., bottom surface is accumulated into line, is stirred in order to dial nail Gear.

With reference to figure 12, the boss 404 in the present embodiment is round boss, and eight semicircles are offered in the boss face Spherical limiting groove 4041.

The gear 401 of the utility model is fixed in rotation axis 408, can only be rotated.Gear peak position 406 is fillet Peak position, it is therefore an objective to driven pinion mate can preferably be held up in this position, anodontia fillet is to more smoothly pass over.

With reference to figure 15 and Figure 16, gear paddy position 407 is also the circular arc type that evagination arches upward, in order to prevents driven gear 409 are stuck in two Gu Feng lowest points, and the arc of outer lug, just preferably can hold up engagement driven gear 409, therefore, specially The peak-to-peak paddy position of cross gear two is designed as outwardly convex and the circular arc with this cross gear for concentric circles.

409 diameter of driven gear in the present embodiment is subject to the restriction of gear peak position 406 and gear paddy position 407.If from The diameter of moving gear 409 is excessive, then it can not rotary motion to the lowest trough position center of cross gear, it could even be possible to by card It cannot extremely be rotated between two peak positions 406 of cross gear, therefore the size of driven gear 409 is by adjacent gear arm gear peak position The width of gear paddy position 407 between 406 determines.

The utility model under the effect of external force, i.e., by small group nail 34 be placed in two adjacent sector structures 403 between, external force When stirring the small group of rotation of nail 34 so that sector structure 403 starts to rotate, rotating direction and the force direction one of small group of nail 34 Cause.

Since the inclined-plane of sector structure 403 and the vertical plane of step are contacted with small group of nail 34 against shake-up, 34 are followed closely when small group When stirring the step of 403 end face of sector structure and rotating counterclockwise, since the sector structure and gear 401 are linked as in itself One, so gear 401 also rotates with.It is pitch wheel between driven gear 409 and gear arm 402, ten Font gear is rotated around the rotation axis 408 of itself, so as to drive driven gear 409 to rotate together.

With reference to figure 13 and Figure 14, the utility model in specific implementation, when mounted at the opposite place of boss 404, is equipped with The banking pin 37 being mutually clamped with limiting groove 4041, is equipped with banking pin spring 38 on the banking pin 37.

Driven gear 409 in the present embodiment while rotating, it also occur that the change of position.I.e. when external force promotion is small Nail 34 is dialled when rotating forward, is aligned when banking pin 37 is rotated to the limiting groove 4041 on 401 back side boss 404 of gear When, banking pin 37 enters in the limiting groove 4041, realizes spacing function.

Cross gear is forced to stop at this time, because on boss 404, the circular central around gear 401 is beaten Eight location holes, the angle between each positioning limit hole are just 45 degree, so when rotating, can play the certain angle of rotation Degree, realizes the function of positioning gear 401.Therefore after cross gear rotates 45 degree, it is inevitable to reach limiting groove 4041 Can temporarily it stop.

With reference to figure 15 and Figure 16, if the utility model middle gear body 401 is before rotation is started, the first driven small tooth of engagement The position of wheel 41 is in the lowest trough position of cross gear, and at this moment cross gear 401 first engages after rotation is started The position of driven pinion 41 also just rotary motion to stopping on the position of the peak peak position of cross gear.Ten Font gear is rotated around the rotation axis 408 of itself, therefore its movement locus is still circular.After 45 degree of rotation, it Only paddy position and the position of peak position change.

Since the shape of the utility model is cross, but due to first engagement driven pinion 41 and second engagement from Dynamic pinion gear 42 is intermeshed together with gear arm all the time when rotating, therefore due to such appearance structure feature, is changed The track that engagement driven pinion 41 and second engages 42 rotary motion of driven pinion is become, has no longer been just round or oval Shape, but it is cross as cross gear external form.Therefore such movement locus, changes making for current gear industry Use scope.The range in gear application is expanded.Since moving line changes, so as to targetedly solve and meet this Application in the machine driving of the non-round movement of class and whole machinery field.And the utility model is just between them Alternating movement path line in paddy peak is as mechanically operated application.

In the present embodiment, the movement locus that driven pinion 42 is engaged due to the first engagement driven pinion 41 and second is existed Moved under the drive of cross gear 401, the track formed is cross.By the rotation of gear 401, make One engagement driven pinion 41 and second engages driven pinion 42 along gear arm 402 by gear peak position 406 and gear paddy position 407 carry out alternate rotation, to drive the first telescopic rod 47, the second telescopic rod 48 to form periodic straight reciprocating motion, realize Locking and the technique effect unlocked.

With reference to figure 1, Fig. 4 and Fig. 5：Flexible force transmission mechanism 300 in the utility model includes such as lower component：The-engagement It is small that driven pinion 41, second engages driven pinion 42, the U-shaped seat 43 of the first pinion gear, the U-shaped seat 44, first of the second pinion gear Gear fixing axle and nut 45, the second pinion gear fixing axle and nut 46, first interlock telescopic rod 47, second and interlock telescopic rod 48th, first interlock telescopic rod fixing glue 49, second interlock telescopic rod fixing glue 50, first interlock telescopic rod resetting spring 51, with And second interlock telescopic rod resetting spring 52.

Then after the cross gear 40 of above two level rotational force mechanism 200 rotates the process at 45 degree of angles, due to The first engagement driven pinion 41 and second at upper and lower two engages driven pinion 42, is nibbled all the time with actively cross gear 40 Conjunction contacts.When actively cross gear 40 above rotates 45 degree counterclockwise to the right from paddy position, since gear is intermeshed The principle of movement causes the first engagement driven pinion 41 and the second engagement driven pinion 42 in actively cross gear 40 In external form, start to stop from paddy position swing offset to the peak position of cross gear 40.

Above-mentioned the reason for stopping is due to that the rotation of actively cross gear 40 has stopped, additionally, due to the first engagement Driven pinion 41 and second engages the driven pinion 42 corresponding U-shaped seat 43 of the first pinion gear assembled, the second pinion gear U therewith Type seat 44, the first pinion gear fixing axle 45 corresponding with them, the second pinion gear fixing axle 46 have all also arrived spaced motion Position thus be forced to stop, and first interlock telescopic rod 47 and second interlock the 48 and first U-shaped seat of pinion gear of telescopic rod 43rd, the U-shaped seat 44 of the second pinion gear interlocks telescopic rod fixing glue 49, second by first and interlocks the connection fixation of telescopic rod fixing glue 50 Together.

Therefore when the U-shaped seat 43 of the first pinion gear, the U-shaped seat 44 of the second pinion gear move to peak position and stop, and first connects The dynamic gearing of telescopic rod 47 and second telescopic rod 48 has also just extended outward to spacing place in lock body and has also stopped, and first interlocks Telescopic rod 47 and second interlocks telescopic rod 48 corresponding first and interlocks 51 and second gearing telescopic rod of telescopic rod resetting spring Resetting spring 52 belongs to downtrodden state, this door for meaning that at this time belongs to the state of locking in summary.

When cross gear 40 45 degree of angles of rotation counterclockwise again under the effect of external force, with described above, due to The principle of the movement of engagement, at this moment so that the first engagement driven pinion 41 and second engages driven pinion 42 in active cross The peak position vertex of type gear 40 starts upper to the paddy of cross gear 40 position from peak position swing offset and stops.So cause with The assembling U-shaped seat 43 of the first pinion gear, the U-shaped seat 44 of the second pinion gear that are fixedly connected, and the first small tooth corresponding with them Wheel fixing axle 45, the second pinion gear fixing axle 46 have all moved back into original position again, and first interlocks the company of telescopic rod 47 and second Dynamic telescopic rod 48 is respectively in the first elastic force effect for interlocking 51 and second gearing telescopic rod resetting spring 52 of telescopic rod resetting spring Under also returned to original position.

And the first gearing telescopic rod resetting spring 51 and the second gearing telescopic rod resetting spring 52 belong to the nature of beginning State, this door for meaning that at this time belong to the state of unlock, and door can be opened.This completes three-level in summary to stretch The function of the telescopic process of force transmission mechanism 300.

With reference to shown in figure 1 and Figure 17, the utility model further includes a reduction resistance elements 400, works as primarily to reducing The U-shaped seat 43 of first pinion gear, the peak position of the second pinion gear U-shaped seat 44 toward cross type gear 40 run into strong resistance when in rotary moving And that designs unloads resistance elements.

The reduction resistance elements 400 mainly include：Lock housing sliding block stop pin after lock housing sliding block stop pin 53, second after first 54th, lock housing sliding block 57 after lock housing sliding block stop pin 56, first after lock housing sliding block stop pin the 55, the 4th after the 3rd, lock housing after second Lock housing sliding block limits before lock housing sliding block reseting spring leaf 60, first after lock housing sliding block reseting spring leaf 59, second after sliding block 58, first Lock housing sliding block stop pin 64 before lock housing sliding block stop pin the 63, the 4th before lock housing sliding block stop pin the 62, the 3rd before position nail 61, second, Lock housing is slided before lock housing sliding block reseting spring leaf 67 and second before lock housing sliding block 66, first before lock housing sliding block 65, second before first Block reset spring leaf 68.

In order to which this strong resistance is reduced or eliminated, first in rear lock shell 1, the first pinion gear fixing axle of preceding lock shell 2 45 and second pinion gear fixing axle 46 motion guide hole be stressed larger inner side expand, it is therefore an objective to when with cross gear 40 It when rotating counterclockwise to the right, can produce outside a kind of rotating central rotation power of counter clockwise direction, can also produce one kind forwards Power, be the power to right front for the first driven pinion 41, and be to the left for the second driven pinion 42 The power in front, therefore this two bursts of forward power will act on the first engagement driven pinion 41 and second being engaged with and engage On driven pinion 42, and first engagement driven pinion 41 then act in its rotation fixing axle 45, and second engagement from Dynamic pinion gear 42 is then acted in its rotation fixing axle 46, since this two rotation fixing axles not only can only be in the guiding of lock housing Move up and down back and forth in groove, therefore axial wall is also directly contacted with the cell wall in the guide groove of lock housing.

Powerful frictional resistance thus is produced, is reduced in order to which this frictional resistance is weakened, the utility model is increased by setting Count this and reduce resistance elements 400.The premise for reducing resistance elements 400 is the first pinion gear fixing axle 45 in lock housing and the The forward pressure direction reaming of the cross gear of motion guide of two pinion fixing axle 46.Then guide runner is consolidated with pin Be scheduled on rear lock-shell lining and preceding lock-shell lining on, be loaded on spring leaf and just complete this and reduce resistance elements 400 parts Assembling, so that the pressure that the first pinion gear fixing axle 45 and the second pinion gear fixing axle 46 are subject to does not act on lock housing slot On inner wall, but act on the spring leaf of sliding block and sliding block.When resistance is very big, guide runner meeting pressing spring piece shrinks back Allow, when the resistance force diminishes, since the elastic force of spring leaf again pushes up back sliding block original position.

In the utility model first before lock housing sliding block reseting spring leaf before lock housing sliding block reseting spring leaf 67 and second 68 can also be substituted with cylindrical compression spring or circular column draft spring.

Through hole on the sliding block is the circular hole advance and retreat notch 530 of drops or square circular hole, when sliding block not by To the fixation rotation axis pressure of driven pinion effect when, sliding block and sliding block resetting spring belong to nature, sliding block circle The near internal face of the cross gear centre of pitch-row can the fixed pin away from sliding block itself.When sliding block is subject to the fixation of driven pinion During the effect of rotation axis pressure, at this moment sliding block receives the pressure and sliding block resetting spring elastic force phase of the fixation rotation axis of pinion gear The state of interaction, when pressure is more than elastic force, sliding block circular hole will be close to sliding block away from the near internal face of cross gear centre The fixed pin of itself.The pressure that resetting spring is subject at this time is maximum, when pressure is less than elastic force, or even during no pressure, is resetted Spring will promote sliding block to return to original position, and sliding block and sliding block resetting spring belong to nature at this time.

The purpose of advance and retreat notch 530 is effectively suitably to be avoided for the advance and retreat of sliding block to provide buffering.And in this practicality New rear lock shell 1 and the larger inboard aperture that is stressed of the pinion gear rotation fixing axle pilot hole of preceding lock 2 big plate face of shell Expanded accordingly on wall, exactly avoided to realize that such advance and retreat are appropriate to provide buffering.

Due to it is described in the utility model it is cross intermeshing is contacted with pinion gear when, when pinion gear is in cross gear Paddy position start peak position toward cross gear it is in rotary moving when, since cross gear and pinion gear are intermeshed, cross gear Rotation counterclockwise can produce the active force of the rotation for driving pinion gear to rotate and move and movement, when cross gear rotate to Pinion gear reaction is maximum to the resistance of cross gear during a certain angle, at this moment since resistance is maximum, same cross gear Also reaction is in pinion gear for resistance, and due to the principle of active force and reaction force, pinion gear is in rotary moving to peak position at this time Resistance will be also the largest, therefore pinion gear will face can not be further continued for rotating the danger moved toward cross gear highest peak shift, For the most this resistance that disappears.The utility model has been specifically designed above-described reduction resistance elements 400, can Allow pinion gear to drive the rotation fixing axle 45,46 and two of its own to interlock telescopic rod to continue to rotate to away from cross gear direction It is mobile, and can disappear and fall most resistance.

When cross gear and pinion gear intermeshing rotary motion, when the resistance between them slowly becomes larger, and small tooth Wheel is fixedly connected with fixing axle, and at this moment pinion gear can be transmitted in this resistance in fixing axle, since fixing axle is again straight with sliding block Contact, and sliding block is movable, therefore there is no much reaction forces to resist caused by cross gear and pinion gear Pressure, slowly can promote sliding block to move out yielding along advance and retreat slot, when cross gear when the pressure between them becomes larger During in place position of certain in rotary moving with pinion gear, pressure can slowly diminish, under the action of above-mentioned spring leaf elastic force, So that sliding block slowly return, therefore promoted the fixing axle return of pinion gear, so that the movement locus of this section of pinion gear is again Return on the track up and down reciprocatingly to move along a straight line.

The utility model employs one-touch button 4, easy to operate direct, and a button can be achieved with world latch and interlock The stretching and contraction of bar.

One-touch button 4 in the utility model is limited in through stainless steel shield lock panel and lock body shell side, positioning In sleeve, by pushing down U-shaped compression bar arm, compression bar arm be lever principle, initially by people finger press external force act on by On button, compression bar upper-arm circumference is around fulcrum shaft rotary oscillation to the right, and compression bar arm will when rotary oscillation resets to the left be returned by resetting spring Position.

When compression bar arm 8 rotates clockwise to the right swing around compression bar arm rotation fixing axle 9, the upper end of oscillating rod 12 is with regard to passive Banking pin in the U-shaped tiger's jaw of pressure arm bar is forced to stir and moved toward the left side, and the spring on oscillating rod causes oscillating rod to swing more Add rapid stronger.

The lower end of oscillating rod 12 is fixedly connected by rotation axis and nut 16 with being driven the forearm of bend arm 15, bend arm 15 Be fixed on lock housing it is front and rear on, can only left rotation and right rotation, it is impossible to the movement of position occurs.When swing is turned left in oscillating rod front end, its Lower end drives bend arm 15 to rotate clockwise to the right.And the rear end of bend arm 15 is further through rotation axis and transmission both arms 18 Front end connects, since bend arm 15 is dextrorotary while can produce two kinds of power, one be the power that promotes to the right and one downwards The rotary force of movement.

The rear end for being driven both arms 18 is connected further through axis and nut 21 with transmission U-type groove 20, and 20 lower end of transmission U-type groove fills There is power-assisted roller 22 free to rotate.And power-assisted scroll wheel 22 is directly contacted with rear lock 1 inner wall of shell, that is to say, that power-assisted is rolled Lock shell 1 cannot be moved down after driving wheel 22 is limited to, and the movement that can only turn right, scroll wheel can produce very when being extruded with lock housing wall Big pressure and frictional force, in transmission U-type groove 20 the power-assisted roller 22 that is assembled be then can be with free rolling roller, because before this The power moved downward that face produces is forced to change direction, and the thrust for movement of turning right therewith is superimposed to form consistent movement of turning right Thrust.

Transmission 20 right flank of U-type groove is fixed together with actuator push rod 24 again.Therefore when bend arm 15 is multiple counterclockwise During the rotation of position, no pressure acts at this time, and bend arm 15, be driven both arms 18 and be driven the distance of associated nodes at U-type groove 20 3 just Can mutually it draw close.But when bend arm 15 rotates clockwise, acted at this time be subject to power to the right, bend arm 15, transmission both arms 18 will turn right with the distance for being driven associated nodes at U-type groove 20 3 as the arm of people stretches expansion, and particularly transmission is double Arm 18 can approach level and stretch to the right, and is driven U-type groove 20 and fixation, 24 right side of actuator push rod and master are connected with actuator push rod 24 Power sliding piece actuating type contacts.

Therefore actuator push rod 24, which promotes to the right, will promote main force's sliding piece to be rotated to upper right.But poke rod passes through small group Nail 34 promotes the core part of the utility model（Cross gear）On height fan step by upper right side counterclockwise revolve Turn, and fan driver plate is connected with cross gear, suspends after 45 degree of angles of fan disc spins of cross gear 40 are promoted Get off, will cause the peak position of cross 40 gear and the position alternate change of paddy position.

It is intermeshed since cross gear 40 engages the engagement driven pinion 42 of driven pinion 41, second with first again Contact, the rotation of cross gear 40, which has driven, is fixed on the first engagement driven pinion 41, second engagement driven pinion 42 Also and then rotate, and pinion stand interlocks telescopic rod 48 with the first gearing telescopic rod 47, second of outer casing spring and is connected fixation.

Not only occur on cross gear 40 since the first engagement driven pinion 41, second engages driven pinion 42 Outside rotation, the movement of position also occurs, if the first engagement driven pinion 41, second engages driven pinion before movement 42 position is the Gu Weishi in cross gear, then after and then rotation is stopped, the first engagement driven pinion 41, second Stop in the peak position of cross gear 40 position of engagement driven pinion 42.

If instead the position that the first engagement driven pinion 41, second engages driven pinion 42 before movement is in cross During the peak position of type gear 40, then after rotation is stopped, the first engagement driven pinion 41, second engages driven pinion 42 Position must be stopped on the paddy position of cross gear 40.

Since the first engagement driven pinion 41, second engages driven pinion 42, the U-shaped seat 43 and second of the first pinion gear The U-shaped seat 44, first of pinion gear interlocks the gearing telescopic rod 50 of telescopic rod 49, second and is all connected and fixed, when the first engagement It is the Gu Weishi for being located at cross gear 40 that driven pinion 41, second, which is engaged after driven pinion 42 stops, and first interlocks Telescopic rod 49, second interlocks telescopic rod 50 and is contracted in lock body, and door at this time belongs to the state that unlock is opened the door.

If instead it is to be located at cross when the first engagement driven pinion 41, second is engaged after driven pinion 42 stops During the peak position of type gear 40, the first gearing telescopic rod 49, second, which interlocks telescopic rod 50, to be stretched out outside lock body, door category at this time In the state of upper locking door.

It is to realize so-called one-touch button point to start the function of stretching with contracting by above-mentioned action.And above-mentioned practicality is new The rotating fulcrum of compression bar arm in the type then almost far pressure spot from this pressure arm, this is the principle for having used lever, separately The lower end of outer above-mentioned transmission U-type groove 20 is equipped with bearing and can freely roll, and the purpose so designed is also for greatly reducing zero Frictional force between part, these comprehensive structural principles so that the utility model practicality is got up not only laborsaving, but also is saved trouble, is greatly improved The speed opened the door and locked a door.

Main force's sliding piece is stuck in practice in order to prevent for the utility model, employs the technological means of fool proof, separately Outer is exactly a little to reduce small group of 34 frictional force back and forth of nail, so as to extend the service life of part.

The realization of the two functions, technological core are the rotating hole of 30 rotation axis of main force's sliding piece, as this Kong Weizheng When circular, main force's sliding piece 30 under the effect of external force, complete cross gear 40 to stir to rotate to limit by round small group of nail 34 After fixed angle, it is due to the effect of 32 elastic force of main force's sliding piece resetting spring under normal circumstances, main force's sliding piece 30 is retracted It is in situ.

When small inclination or clamping occur for cross 40 fan disk of gear, at this time if main force's sliding piece 30 and small group of nail 34 32 strength of spring that is reset retracts, then small group of nail 34 is possible to be blocked and drawn not by certain point of cross 40 fan disk of gear Return.

Situation above occurs in order to prevent, and the rotating hole of 30 rotation axis of main force's sliding piece is changed to ellipse by the utility model During the hole position of shape, if still running into when blocking event of the above, one is the effect of 32 pulling force of resetting spring, can dial the main force Movable plate 30 and small group of nail 34 are held always；The second is since the rotating hole of 30 rotation axis of main force's sliding piece is changed to slotted eye 290 Afterwards, 30 rotation axis of main force's sliding piece is no longer dead by limited circular hole position limitation, due to the effect of 32 pulling force of resetting spring, makes A little displacement or or bounce can be occurred by obtaining the rotary middle point of 30 rotation axis of main force's sliding piece.

Therefore, when free displacement or bounce occur for 30 rotation axis of main force's sliding piece, cross 40 fan disk of gear Inclined-plane just blocks incessantly small group of nail 34, so as to ensure that main force's sliding piece 30 is possible to the phenomenon being stuck.In addition, ellipse is given The activity space of 30 rotation axis of main force's sliding piece more loosens, and space is looser natural.When 30 rotation axis of main force's sliding piece becomes larger After loosening, when compared with circular hole before, the frictional force on the 40 fan disk inclined-plane of cross gear of small group of nail 34 can become It is small.Therefore small group of 34 frictional force back and forth of nail is reduced, so as to extend the service life of part.

Such as Figure 18, in addition the utility model provides the selection of multinomial property for user, and expanded the utility model The application of other forms.

First, the last working part of the utility model is to interlock telescopic rod, and portion of the telescopic rod outside this lock body It is divided into thread shape.If client likes being connected with this lock body with the world connecting rod of thread shape, then this lock body is with regard to prewired below figure With the structure for lengthening formula screw rod 600, the two gearing telescopic rods that nut is tightened in the utility model are added on the screw rod 600 47th, on 48, allow the world connecting rod of client to be directly threaded into this nut and dock.
