Background
The mechanical lock comprises a mechanical lock body and a handle, wherein the mechanical lock body comprises a lock shell, a power transmission structure accommodated in the lock shell and a lock tongue which moves back and forth under the driving of the power transmission mechanism. And a power transmission shaft is arranged between the handle and the power transmission mechanism, the power transmission shaft is commonly called square iron or flat iron in the industry, and the handle becomes a power input end of the power transmission mechanism. The square iron is often relatively long, and if the square iron is integrally formed with the handle, the manufacturing of the handle is inconvenient, and the later packaging and transportation are inconvenient. In view of this, as shown in fig. 7, it is common practice in the industry to separately provide a power transmission shaft 2 and a handle 1, provide a socket hole for plugging the power transmission shaft 2 on the handle 1, and then connect the handle 1 with the power transmission shaft 2 by a pin 3 to form a radial linkage relationship between the handle 1 and the power transmission shaft 2. But this connection does not facilitate the mounting and dismounting of the power transmission shaft 2, and further improvement is required.
Disclosure of Invention
Aiming at the technical problems in the prior art, the invention provides a transition shaft quick-assembly structure which is characterized by comprising a base shaft, a torsion spring and a transition shaft; an axial insertion hole and a pair of left and right transverse through holes which are arranged at the top end part of the base shaft in a separated mode and extend transversely are formed in the top end part of the base shaft, the pair of transverse through holes penetrate through the axial insertion hole, and the head part of the transition shaft can be inserted into the axial insertion hole; the torsion spring comprises a pair of arc-shaped clamping arms, the torsion spring can be embraced on the base shaft through the pair of arc-shaped clamping arms, and part of arm bodies of the pair of arc-shaped clamping arms respectively penetrate through the pair of transverse through holes to extend into the axial insertion holes; the transition shaft is characterized in that a pair of pits which are arranged left and right are formed in the head of the transition shaft, when the head of the transition shaft is inserted into the axial insertion hole, the pair of arc-shaped clamping arms are respectively clamped on the pair of pits so as to clamp the transition shaft, the transition shaft cannot easily fall out of the axial insertion hole, and the transition shaft can be conveniently pulled out by utilizing elastic deformation of the pair of arc-shaped clamping arms.
The pair of transverse through holes can be hole parts arranged on the same horizontal line, and the scheme can be formed by transversely penetrating the base shaft through a drilling tool in the machining process at one time. In addition, the pair of transverse through holes may be hole portions arranged vertically offset along the axial direction of the base shaft.
The arc-shaped clamping arm is an arm body capable of defining an encircling space on the inner side of the arc-shaped clamping arm through a mechanical structure of the arc-shaped clamping arm, the arc-shaped clamping arm is not limited to a standard arc shape, and the arc-shaped clamping arm can also be in other similar arc shapes and can form an encircling space, such as a door frame shape.
The pair of pits may be two sections of concave parts arranged in a concave ring extending continuously on the head of the transition shaft, or concave parts arranged at intervals on the head of the transition shaft.
According to the technical scheme, compared with the prior art, the invention has the beneficial technical effects that: because the partial arm bodies of the arc-shaped clamping arms respectively penetrate through the pair of transverse through holes to extend into the axial insertion holes, when the head of the transition shaft is inserted into the axial insertion holes, the arc-shaped clamping arms are expanded under the extrusion of the head of the transition shaft so that the transition shaft can continue to be inserted downwards, and when the pit slides downwards to the arc-shaped clamping arms, the arc-shaped clamping arms are mutually close to be clamped on the pit. Therefore, the transition shaft is clamped by the combination of the concave pits and the arc clamping arms, so that a relatively stable connection relation can be formed between the transition shaft and the base shaft, and the transition shaft cannot easily fall out of the axial insertion hole. However, the arc-shaped clamping arms have certain elastic deformation capability, so that the connection relationship can be changed in a relatively convenient manner, namely, when the transition shaft is reversely pulled upwards, the transition shaft reversely extrudes a pair of arc-shaped clamping arms to enable the arc-shaped clamping arms to elastically deform and moderately expand, so that the transition shaft is released. Therefore, in the scheme, the requirements of quick assembly and stable assembly between the transition shaft and the base shaft are met, and the requirement of convenient disassembly of the transition shaft is also met.
In order to enable the transition shaft to be inserted into the axial insertion hole relatively easily and smoothly, a further technical solution may be that a guide slope surface is provided at the top end of the transition shaft head. Or, in a further technical scheme, a pair of arc-shaped clamping arms are respectively formed with a back-shaped bending part, and the back-shaped bending parts can be inserted into the axial insertion holes through the transverse through holes. The annular bending part is provided with an axially arranged arc-shaped head part, and the axial direction refers to the inserting direction of the transition shaft to the base shaft. Therefore, when the transition shaft is extruded onto the return bending part, under the action of the circular arc-shaped head part, the head part of the transition shaft can relatively easily push and push the pair of arc-shaped clamping arms to open so as to be smoothly inserted between the pair of arc-shaped clamping arms, and conversely, the transition shaft can be conveniently pulled out from between the pair of arc-shaped clamping arms. In addition, the structural strength of the arc-shaped clamping arm can be enhanced by means of the return-shaped bending part, so that the problem that the clamping force on the transition shaft is influenced due to destructive deformation of the arc-shaped clamping arm after long-term use is avoided.
In order to make the transition shaft more conveniently withdraw from the axial insertion hole, the further technical scheme may be that a side wall of the pit, which is close to one side of the transition shaft head, is arranged in an inclined manner. In this way, the magnitude of the extraction force can be controlled when the angle between the side wall and the central axis of the base shaft is reasonably arranged, so that the axial insertion hole can be extracted when a certain force is applied to the transition shaft.
The invention also provides a lockset applying the transition shaft quick-mounting structure, which comprises a lock plate body and a handle exposed outside the lock plate body, wherein the tail end part of the base shaft passes through the lock plate body from inside to outside and is connected to the handle.
The further technical scheme can be that the lock comprises a static positioning arm which is positioned at the inner side of the lock plate body and fixedly connected with the lock plate body through a connecting arm; the movable positioning arm is axially sleeved on the base shaft in a sliding manner and is in radial linkage with the base shaft, and the movable positioning arm and the static positioning arm are arranged front and back in the axial direction of the base shaft; the movable arm positioning device comprises a base shaft, and is characterized by further comprising a movable arm reset spring, wherein the movable arm reset spring can drive the movable positioning arm to be abutted against the static positioning arm, a concave-convex abutting structure is arranged on an abutting working surface between the movable positioning arm and the static positioning arm, and when the movable positioning arm is driven by the base shaft to radially rotate relative to the static positioning arm, each step of rotation can be positioned by means of the concave-convex abutting structure. In this way, the base shaft can be positioned by the stationary positioning arm and the movable positioning arm to prevent the base shaft from rotating at will to affect the operation of other members, and also a single-step rotation angle of the base shaft, for example, a single-step rotation of 90 °, can be determined by means of the concavo-convex abutment structure. In addition, as the movable positioning arm and the static positioning arm are in axial arrangement, the installation space occupied by the movable positioning arm and the static positioning arm in the direction parallel to the lock plate body can be reduced, and more installation space can be provided for other functional components.
The further technical scheme can be that the device further comprises a trigger device capable of rotating along with the radial direction of the base shaft, and further comprises an induction detector and a central controller, wherein the induction detector is used for receiving a trigger signal which the trigger device rotates through and transmitting an induction signal corresponding to the trigger signal to the central controller. Wherein the trigger signal may be a mechanical signal, an optical signal, a magnetic signal, etc. Therefore, the information such as the rotation times and the rotation time point of the base shaft can be obtained through the trigger device and the induction detector, and the lockset can be further intelligently managed after the information is obtained, for example, a prompt signal that the knob is rotated is sent, so that a user can know the service condition of the lockset.
Because the invention has the characteristics and the advantages, the invention can be applied to equipment which needs to be spliced and disassembled for two split shaft bodies, such as a counter-lock knob and a handle of a lockset.

Detailed Description
As shown in fig. 1 and 2, a lock 100 with a knob positioning structure is shown, the lock 100 includes a lock plate 1 and a knob 2 rotatably mounted on the lock plate 1. The knob 2 includes a handle 21 exposed to the outside of the lock plate 1, and a base shaft 22 penetrating the lock plate 1 and coupled to the handle 21. In this embodiment, the lock plate body 1 is a decorative plate. Of course, in other embodiments, the lock plate body 1 may also be part of a lock housing arranged inside the decorative panel, the lock housing being used for accommodating components such as a bolt.
The inside of the lock plate body 1 is provided with a static positioning arm 3 and a connecting arm 9, and the static positioning arm 3 is fixedly connected to the lock plate body 1 through the connecting arm 9. An anti-rotation plug-in mechanism is arranged between the connecting arm 9 and the static positioning arm 3. Of course, in other embodiments, the stationary arm 3 and the connecting arm 9 may be formed as a single piece, and the anti-rotation plug-in mechanism may be omitted. The anti-rotation plug-in mechanism comprises a positioning plug 91 and a positioning hole 32, wherein the cross sections of the positioning plug 91 and the positioning hole are respectively non-circular and are arranged in an adaptive manner. The cross-sectional shapes of the positioning plug 91 and the positioning hole 32 may be various. In the present embodiment, the cross-sectional shape of the positioning hole 32 is substantially identical to the cross-sectional shape of the positioning plug 91, and is hexagonal, wherein the positioning plug 91 is provided on the connecting arm 9, and the positioning hole 32 is provided on the stationary positioning arm 3. The static positioning arm 3 is inserted into the positioning plug 91 through the positioning hole 32, and then a screw is screwed on the positioning plug 91 to fixedly connect the static positioning arm 3 to the connecting arm 9. The static positioning arm 3 is also provided with an annular hole 30, and the annular hole 30 and the positioning hole 32 are arranged left and right. The tip end portion of the base shaft 22 is inserted into the annular ring 30 and is rotatable in the annular ring 30. In this way, the annular hole 30 of the static positioning arm 3 does not obstruct the rotation of the base shaft 22, and the rotation of the base shaft 22 does not drive the static positioning arm 3 to rotate.
The movable positioning arm 4 is further provided between the stationary positioning arm 3 and the lock plate body 1, but it is needless to say that the stationary positioning arm 3 may be disposed between the movable positioning arm 4 and the lock plate body 1 in other embodiments. The movable positioning arm 4 is axially and slidably sleeved on the base shaft 22 and is in radial linkage with the base shaft 22, and the movable positioning arm 4 and the static positioning arm 3 are arranged back and forth in the axial direction of the base shaft 22. A movable arm reset spring 5 is further arranged between the lock plate body 1 and the movable positioning arm 4, and the movable arm reset spring 5 is sleeved on the base shaft 22 in a penetrating way. The movable arm return spring 5 can drive the movable positioning arm 4 to abut against the stationary positioning arm 3, and concave-convex abutting structures (31, 41) are arranged on abutting working surfaces between the movable positioning arm 4 and the stationary positioning arm 3, so that each step of rotation can be positioned by means of the concave-convex abutting structures (31, 41) when the movable positioning arm 4 is driven by the base shaft 22 to radially rotate relative to the stationary positioning arm 3. The concave-convex abutting structure 31 is a concave-convex structure, and includes a peak portion 311, a bottom valley portion 312, and an inclined surface 313 connected between the peak portion 311 and the bottom valley portion 312. The concave-convex abutting structure 41 and the concave-convex abutting structure 31 have matched structures, and also have a peak 411, a bottom valley 412, and an inclined surface 413. The movable positioning arm 4 and the stationary positioning arm 3 are engaged with each other by the concave-convex engagement of the concave-convex abutting structures (31, 41), so that the movable positioning arm 4 is positioned in the radial direction. As shown in fig. 3, when a radial torsion moment is applied to the base shaft 22 by the handle 21 to drive the movable positioning arm 4 to rotate radially relative to the stationary positioning arm 3, the crest 411 on the movable positioning arm 4 abuts against the inclined surface 313 on the stationary positioning arm 3 and continues to rotate radially under the guidance of the crest while sliding axially in a direction away from the stationary positioning arm 3, so that the engagement between the movable positioning arm 4 and the stationary positioning arm 3 is temporarily released. In this process, the movable positioning arm 4 presses the movable arm return spring 5 to be contracted and deformed. When the crest 411 of the movable positioning arm 4 radially rotates beyond the bottom valley 312 of the stationary positioning arm 3, the movable positioning arm 4 axially slides in a direction approaching the stationary positioning arm 3 under the pushing of the movable arm return spring 5 to be clamped to the stationary positioning arm 3 again, and the movable positioning arm 4 rotates by one step and is positioned, and simultaneously, the base shaft 22 is positioned by the movable positioning arm 4. If the torque continues to be applied to drive the base shaft 22 to rotate, the movable positioning arm 4 will continue to rotate radially, but will be positioned once per rotation step. It follows that when the movable positioning arm 4 is rotated radially with respect to the stationary positioning arm 3 by the base shaft 22, it is possible to position each rotation by means of the concave-convex abutting structure (31, 41).
In addition, the layout positions of the boom return springs 5 may be varied. In other embodiments, the movable arm return spring may be disposed between the movable positioning arm 4 and the stationary positioning arm 3, and the movable positioning arm 4 may be pulled to move in the direction of the stationary positioning arm 3 by the movable arm return spring; in this case, the stationary positioning arm 3 may be disposed between the movable positioning arm 4 and the lock plate body 1, and the movable positioning arm 4 may be pushed by the movable arm return spring to move toward the stationary positioning arm 3.
According to the above-described technical solution, it can be found that, firstly, since each step of rotation of the movable positioning arm 4 can be positioned by means of the concavo-convex abutment structure (31, 41), the base shaft 22 can be positioned to prevent the base shaft 22 from rotating arbitrarily to affect the operation of other members, and also a single-step rotation angle of the base shaft 22, for example, a single-step rotation of 90 ° can be determined by means of the concavo-convex abutment structure (31, 41). In addition, as the movable positioning arm 4 and the static positioning arm 3 are arranged back and forth in the axial direction of the base shaft 22, the installation space occupied by the movable positioning arm 4 and the static positioning arm 3 in the direction parallel to the lock plate body 1 can be reduced, and more installation space is provided for other functional components.
As shown in fig. 1, further, a triggering device 6, an induction detector 600 and a central controller (not shown in the drawing) are further disposed on the inner side of the lock plate body 1, wherein the triggering device 6 is a cam. The cam 6 is provided with a connecting through hole 61, and the cam 6 is sleeved on the base shaft 22 through the connecting through hole 61 and is in radial linkage with the base shaft 22, so that the cam 6 can radially rotate along with the base shaft 22. The cam 6 is abutted against the inner side of the lock plate body 1, the movable arm reset spring 5 is arranged between the cam 6 and the movable positioning arm 4, one end of the movable arm reset spring 5 is abutted against the movable positioning arm 4, and the other end is abutted against the cam 6. The sensing detector 600 is configured to receive a trigger signal that the protrusion 62 of the cam 6 rotates through and transmit a sensing signal corresponding to the trigger signal to the central controller. In this way, the triggering device and the sensing detector 600 can acquire information such as the rotation times and the rotation time points of the base shaft 22, so that the lock 100 can be further intelligently managed after acquiring the information, for example, a prompt signal that the knob 2 has been rotated is sent, so that a user can know the service condition of the lock.
As shown in fig. 4, 5 and 6, the lock 100 further includes a torsion spring 8 and a transition shaft 7, an axial insertion hole 221 and a pair of left and right spaced and laterally extending lateral through holes (222, 222 a) are provided at a top end portion of the base shaft 22, the pair of lateral through holes (222, 222 a) penetrate the axial insertion hole 221, and a head portion 71 of the transition shaft 7 can be inserted into the axial insertion hole 221. The torsion spring 8 includes a coil body 81 and a pair of arcuate snap arms (82, 82 a) extending from the coil body 8. The arc-shaped clamping arms (82, 82 a) are arm bodies capable of defining encircling spaces on the inner sides of the arc-shaped clamping arms through the mechanical structures of the arc-shaped clamping arms, the arc-shaped clamping arms are not limited to a standard arc shape, and the arc-shaped clamping arms can also be in other similar arc shapes and can form encircling spaces, such as a door frame shape. The torsion spring 8 is wrapped around the base shaft 22 by a pair of arc-shaped clamping arms (82, 82 a) and allows part of arm bodies of the pair of arc-shaped clamping arms (82, 82 a) to respectively pass through a pair of transverse through holes (222, 222 a) and extend into the axial insertion holes 221. A pair of pits (72, 72 a) which are arranged left and right are arranged on the head part 71 of the transition shaft 7, and the pits (72, 72 a) are concave parts which are arranged at intervals on the head part 71 of the transition shaft. Of course, in other embodiments, the pair of recesses (72, 72 a) may be two-stage recesses provided in a continuously extending recess ring on the head portion 71 of the transition shaft 7. When the head 71 of the transition shaft 7 is inserted downward into the axial insertion hole 221, a pair of arc-shaped clamping arms (82, 82 a) are opened under the extrusion of the head 71 of the transition shaft so that the transition shaft 7 can be inserted downward continuously, and when the pits (72, 72 a) slide down to the arc-shaped clamping arms (82, 82 a), the pair of arc-shaped clamping arms (82, 82 a) are clamped to the pair of pits (72, 72 a) close to each other so as to clamp the transition shaft 7, and therefore the transition shaft 7 cannot be easily separated from the axial insertion hole 221. The coupling of the recesses (72, 72 a) with the arcuate latching arms (82, 82 a) thus enables the transition shaft 7 to be latched such that a relatively stable connection is formed between the transition shaft 7 and the base shaft 22, the transition shaft 7 not being easily removed from the axial insertion hole 221. However, since the arc-shaped clamping arms (82, 82 a) have certain elastic deformation capability, the connection relationship can be changed in a relatively convenient manner, namely, when the transition shaft 7 is reversely pulled upwards, the transition shaft 7 reversely presses the pair of arc-shaped clamping arms (82, 82 a) to enable the pair of arc-shaped clamping arms to elastically deform and moderately expand so as to release the transition shaft 7, namely, the transition shaft 7 can be conveniently pulled out by utilizing the elastic deformation of the pair of arc-shaped clamping arms (82, 82 a). Therefore, in the scheme, the requirements of quick assembly and stable assembly between the transition shaft 7 and the base shaft 22 are met, and the requirements of convenient disassembly of the transition shaft 7 are also met.
In order to enable the transition shaft 7 to be inserted into the axial insertion hole 221 relatively easily and smoothly, a pair of left and right split guide slope surfaces (712, 712 a) are further provided at the top end of the transition shaft head portion 71. The pair of arc-shaped clamping arms (82, 82 a) are respectively provided with a pair of axially-arranged return bending parts (83, 83 a), the return bending parts (83, 83 a) are respectively provided with axially-arranged circular arc-shaped heads (831, 831 a), and the return bending parts (83, 83 a) are respectively inserted into the axial insertion holes 221 through the transverse through holes (222, 222 a). When the transition shaft head 71 is pressed against the return bends (83, 83 a), the transition shaft head 71 can relatively easily push the pair of arc-shaped clamping arms open under the action of the arc-shaped heads (831, 831 a) so as to be smoothly inserted between the pair of arc-shaped clamping arms (82, 82 a), and can be conveniently pulled out from between the pair of arc-shaped clamping arms (82, 82 a). In addition, the structural strength of the arc-shaped clamping arms (82, 82 a) can be respectively reinforced by the aid of the return-shaped bending parts (83, 83 a), so that the clamping force on the transition shaft 7 is prevented from being influenced due to destructive deformation of the arc-shaped clamping arms (82, 82 a) after long-term use.
In order to make it easier to withdraw the transition shaft 7 from the axial insertion hole 221, the side walls (721, 721 a) of the recesses (72, 72 a) on the side close to the head portion 71 are respectively arranged in an inclined manner. In this way, the magnitude of the extraction force can be controlled when the angles between the side walls (721, 721 a) and the central axis of the base shaft 22, respectively, are reasonably arranged, so that the transition shaft 7 can be extracted from the axial insertion hole 221 without being too easy.
