About pawl structure 114, generally, different demands corresponds to the pawl structure of different structure, and the size of pawl structure, knot The detailed structures such as structure, which determine, can precisely, reliably grab target bottle cap.Present embodiment provides two kinds of pawl structure, It is specific as follows:
As a kind of embodiment of pawl structure 114, in conjunction with shown in reference attached drawing 4 and attached drawing 5, pawl structure 114 includes driving Component 1142, claw 1143, the first shell 1144, multiple elastic components 1145, anti-rotation component and second housing 1147.It needs Bright, above-mentioned technical characteristic, but can be according to actual needs it is not necessary to occur simultaneously in the same technical solution It is combined into different technical solutions.Practical pawl structure 114 is exactly for firmly grasping sample bottle cap, during uncapping or closing lid Prevent sample bottle cap from falling or skidding, to influence switch cover operation.In a technical solution, pawl structure 114 be can wrap Include driving assembly 1142, claw 1143, the first shell 1144 and multiple elastic components 1145.The claw 1143 be it is multiple (can also More claws are independent of each other to regard as), the first shell 1144 can be regarded as the installation foundation of claw 1143.Multiple claws 1143 are installed in the first shell 1144, and elastic component 1145 is arranged between two adjacent claws 1143,1143 He of claw First shell 1144 is equipped with the tapered face that is mutually matched, under the limitation of the inner wall of the first shell 1144, multiple claws 1143 it Between elastic component 1145 always be in confined state；When driving assembly 1142 pushes multiple claws 1143 to travel forward, Under the limitation of the inner wall of one shell 1144, multiple claws 1143 be in tightening state；When driving assembly 1142 moves backward (such as The pressing plate of driving assembly hereinafter, nut driving section move backward), each elastic component 1145 elastic force effect under, it is multiple Claw 1143 is in open configuration.Wherein, " forward " in the embodiments of the present invention, " backward " can be understood as it is opposite In " forward " and " backward " with driving assembly (specific it is to be appreciated that relative to the motor in shown in Fig. 1).In practical application In it can be appreciated that diagram in up and down.
Tapered face referred to above refers in the utility model: relative to driving assembly 1142, along far from driving assembly 1142 direction (i.e. forward), the inner edge perimeter of the first shell 1144 and the outer rim perimeter of claw are gradually reduced, it is understood that It is smaller and smaller for external opening for the first shell and claw.Wherein, tapered face can be the conical surface, and the conical surface is advantageously selected for Processing, and also can be big compared to the tapered face (for example, the diminishing arcwall face of radius) of other forms on production cost It is big to reduce.When switching from open configuration to tightening state, during multiple claws 1143 travel forward, due to claw 1143 and first shell 1144 the conical surface to match restriction effect (opening of claw and the first shell is smaller and smaller), it is adjacent The decrement of elastic component 1145 between two claws 1143 is gradually increased, thus the distance between two neighboring claw 1143 by Decrescence small, until the distance between two neighboring claw 1143 is reduced to minimum, multiple claws 1143 are in tightening state at this time. Similarly, when switching from tightening state to open configuration, starting driving assembly 1142, driving assembly 1142 moves backward, thus The thrust to claw 1143 is released, claw 1143 moves backward under the elastic force effect of elastic component 1145, in multiple claws 1143 During moving backward, due to change in size (claw and the of claw 1143 and the conical surface of the first shell 1144 to match The opening of one shell is increasing), the decrement of the elastic component 1145 between two neighboring claw 1143 is gradually reduced, thus phase The distance between adjacent two claws 1143 are gradually increased, until the maximum that the distance between two neighboring claw 1143 increases to, Multiple claws 1143 are in open configuration at this time.
As a kind of deformation, tapered face can also be the diminishing arcwall face of radius, and this tapered face also can use The gradual change of its radius, to realize the tightening and opening of pawl structure.
As another deformation, tapered face can also be the curved surface etc. for the continual curvature that other sizes are gradually reduced.
In the present invention, by the way that using the lesser elastic component 1145 of size, (elastic component can add according to actual needs Work it is very small), and the tapered face for combining claw 1143 and the first shell 1144 to match, so as to by pawl structure 114 Size minimizes as far as possible, can be suitable for carrying out switch cover operation (especially suitable for neighboring samples simultaneously to multiple sample bottles The very small situation of the distance between bottle), realize continuous productive process；And pawl knot 114 in the prior art is due to the limit of its structure System, pawl structure cannot design very small, to can only carry out switch cover behaviour to simple sample bottle when carrying out switch cover operation Make, can not achieve continuous productive process.And the pawl structure in the utility model is under the action of 1145 elastic force of elastic component, while Clamping sample bottle cap that can be very firm under the limitation of the inner wall of one shell 1144, it is not easy to fall.
Pawl structure in present embodiment include tightening state, open configuration and between tightening state and open configuration it Between intermediate state, these three states will be described in detail below:
Assuming that initial conditions are open configuration, when needing to grab using pawl structure 114 and clamp sample bottle cap, that is, It says when pawl structure 114 being needed to be switched to tightening state from open configuration, sample bottle cap is made to be located at multiple pawls of pawl structure 114 first In the space that portion 1143 is formed, then start driving assembly, under the driving of driving assembly, multiple claws 1143 travel forward, During multiple claws 1143 travel forward, due to the limit in the tapered face of claw 1143 and the first shell 1144 to match (opening of claw and the first shell is smaller and smaller) is used in production, the decrement of the elastic component 1145 between two neighboring claw 1143 Be gradually increased, so that the distance between two neighboring claw 1143 is gradually reduced, until between two neighboring claw 1143 away from From minimum is reduced to, multiple claws 1143 are in tightening state at this time, before this it is considered that claw is in intermediate state.
On the contrary, when that is, claw 1143 switches from tightening state to open configuration, starting is driven when needing to unclamp sample bottle cap Dynamic component 1142, driving assembly 1142 move backward, to release the thrust to claw 1143, claw 1143 is in elastic component 1145 Elastic force effect under move backward, during multiple claws 1143 move backward, due to claw 1143 and the first shell The change in size (being gradually increased) in the 1144 tapered face to match, the pressure of the elastic component 1145 between two neighboring claw 1143 Contracting amount is gradually reduced, so that the distance between two neighboring claw 1143 is gradually increased, until between two neighboring claw 1143 The maximum that increases to of distance, multiple claws 1143 are in open configuration at this time, before this it is considered that claw is in centre State.
About driving assembly 1142, for driving assembly 1142 for driving claw 1143 to move, driving assembly 1142 includes dynamic Power part 1142a and running part, power section 1142a may include motor (in order to distinguish, referred to herein as the first pawl structure Motor) (can also include motor housing 1142b, for installing motor), power is provided by motor.
As a kind of deformation, other than it can provide power by motor, the side such as hydraulic-driven, pneumatic can also be passed through Formula provides power.
Illustrate as an example, the running part includes pressing plate 1142c, and the pressing plate 1142c is located at claw 1143 Between power section 1142a, pressing plate 1142c is connect with power section 1142a；As power section 1142c band dynamic pressure plate 1142c When travelling forward, pressing plate 1142c pushes multiple claws 1143 to travel forward, and then multiple claws is made to be in tightening state；When dynamic Power part 1142a band dynamic pressure plate 1142c move backward, each elastic component 1145 elastic force effect under, multiple claws 1143 to After move, and then multiple claws is made to be in open configuration.In the present invention, since multiple claws 1143 are independent mutually Component, therefore when driving assembly 1142 pushes multiple claws 1143 to travel forward, since the presence of pressing plate 1142c can guarantee Multiple claws can be synchronized and be travelled forward, to improve the reliability of total.
As a kind of deformation, running part further includes the first pawl structure lead screw 1142d and nut driving section 1142e, and first Pawl structure lead screw 1142d from the output end of the first pawl structural electromotor stretch out, nut driving section 1142e have centre bore, it is described in The inner wall in heart hole is provided with the internal screw thread for being threadedly coupled with the first pawl structure lead screw 1142d, the nut driving section 1142e It is fixed with pressing plate 1142c.It is in fact possible to regard nut driving section 1142e as a nut, pass through nut and the first pawl structure The threaded connection of lead screw 1142d, so that linear motion is converted by the rotation of the first pawl structural electromotor, so that nut pushes pressing plate 1142c travels forward.
About claw 1143, in conjunction with shown in Fig. 6 and Fig. 7, each claw 1143 includes flat part 1143a and rake 1143b, rake 1143b have the conical surface.In the side close to elastic component 1145, flat part 1143a passes through with rake 1143b Limit end face is collectively formed in step 1143c transition, the respective step 1143c of multiple claws 1143；Multiple claws 1143 it is each From flat part 1143a be collectively formed it is cylindric；Cone-shaped is collectively formed in the respective rake 1143b of multiple claws 1143. Wherein, the formation for limiting end face, which can be determined, grasps the grasping height of sample bottle cap in pawl structure 114, makes 114 standard of pawl structure Change, while is formationed for limiting end face can guarantee the grip locations of sample bottle cap, when especially for sample bottle for glass material, If the position that claw is grasped when grasping is improper, and has gripped the body of sample bottle, to be easy to cause sample bottle Damage, especially for the inspection of some particular samples, sample bottle it is broken may health to staff Damage.
Illustrate as an example, in order to increase the frictional force between 1143 inner wall of sample bottle cap and claw, so that claw The grasping of 1143 pairs of sample bottle caps is tighter, can preferably add in the side of the close elastic component 1145 of each flat part 1143a Work annular knurl or decorative pattern.
As a kind of deformation, can also be increased between sample bottle cap and 1143 inner wall of claw using the structure of other forms Frictional force, such as in structures such as the side setting convex ribs of close elastic component 1145 of each flat part 1143a.
Illustrate as an example, in pawl structure use process, pressing plate 1142c is rotated in order to prevent, can also be arranged Anti-rotation component.Wherein, anti-rotation component can be there are many form, such as can be arranged protrusion in the outer rim of pressing plate 1142c, while Sliding slot is arranged in the inner wall of each claw 1143, the protrusion limitation in this way during pressing plate 1142c is moved, on pressing plate 1142c In the sliding slot of claw 1143, to prevent the rotation of pressing plate 1142c.For another example anti-rotation component can use the shape of telescopic rod Formula, specifically, anti-rotation component includes at least two groups telescopic component 1146, every group of telescopic component 1146 includes extension sleeve 1146a With the telescopic rod 1146b being slidably connected with extension sleeve 1146a, extension sleeve 1146a in every group of telescopic component 1146 and stretch One of contracting bar 1146b is fixed (can specifically fix with motor housing 1142b) with driving assembly 1142, every group of flexible group The other of extension sleeve 1146a and telescopic rod 1146b in part 1146 and pressing plate 1142c are fixed.In the present embodiment, In conjunction with reference attached drawing 5, anti-rotation component includes two groups of telescopic components 1146, specially the first telescopic component and the second telescopic component, In order to guarantee that stress balance, the first telescopic component and the second telescopic component are uniformly arranged (it can be appreciated that the first telescopic component It is uniformly distributed on pressing plate with the fixed point of the fixed point of pressing plate, the second telescopic component and pressing plate), such as pressing plate 1142c is circle When plate-like, the tie point of the first telescopic component and the second telescopic component and pressing plate is located at the same of the same circle on pressing plate 1142c One diametrically.Certainly, anti-rotation component also may include one group of telescopic component, is only easy to cause in this case and accepts injustice The case where weighing apparatus, occurs.
Illustrate as an example, in the telescopic process of telescopic rod 1146b, due to telescopic rod 1146b and extension sleeve It can frequently rub between 1146a, and the structural strength of telescopic rod 1146b is limited, therefore in order to avoid telescopic rod is seriously worn 1146b, it is preferable that be arranged with wearing piece 1146c (for example, sliding axle in one end of the telescopic rod of every group of telescopic component 1146 Hold), wherein wearing piece 1146c is located in extension sleeve 1146a and is interference fitted with extension sleeve 1146a, telescopic rod 1146b It is slidably connected with wearing piece.
In order to guarantee that the components such as anti-rotation component are not easy to be broken or damaged, pawl structure 114 further includes second housing 1147, anti-rotation component is located in second housing 1147, the second housing 1147 respectively with the first shell 1144, driving assembly 1142 is fixed.Attached drawing 5 is referred to specifically, combining, second housing 1147 can be using cylindric, and close to the first shell 1144 One end side on be provided with multiple first mounting holes, accordingly, the one of the close second housing 1147 of the first shell 1144 Multiple second mounting holes are arranged in end, and a part of the end of the first shell 1144 can be inserted in second housing 1147, thus So that the first mounting hole and the alignment of the second mounting hole, to be each passed through the first mounting hole and the second peace by fasteners such as screws It fills hole and fixes second housing and the first shell.Similarly, about second housing 1147 and 1142 (specifically motor of driving assembly Fixation with motor housing 1142b) again may be by fastener realization.
About elastic component 1145, illustrate as an example, the elastic component 1145 can be spring (such as pressure spring, gas Spring etc.), the two sides of each claw 1143 are provided with blind hole 1143e, and the both ends of each spring are only against two neighboring respectively In the opposite two blind hole 1143e of claw 1143, wherein being to guarantee the steady of pawl structure by blind hole 1143e installation spring Qualitative and reliability prevents spring from disengaging, failure.In the present embodiment, claw 1143 is three, accordingly, spring three A, three springs are evenly distributed between three claws.
As a kind of deformation, elastic component is also possible to relatively thin metalwork in irregular shape, since its thickness is smaller, With certain elasticity.
Illustrate as an example, claw 1143 consistently forms line with the inner wall of the first shell 1144 and contacts, line here Contact is contact for face contact, between two components in fact if it is contact (the abbreviation face between face and face Contact), then opposite sliding between the two can be relatively difficult (larger because of frictional force), if the contact between two components is Line directly contacts (contact of abbreviation line) with line, then opposite sliding between the two will be easy very much (friction is small), That is the contact of line employed in the utility model is intended to reduce by two components and (refers mainly to claw 1143 in present embodiment With the first shell 1144) between friction can specifically include more so that opposite sliding between the two can be easier Kind situation finally connects into a line for example, each claw contacts a point with the first shell；For another example, each claw 1143 with All positions of first shell 1144 contact can connect in alignment.
In order to be more clearly understood that pawl structure provided in this embodiment, below in conjunction with specific attached drawing 4 and Fig. 5 to this implementation The installation process of pawl structure in example is described: power section 1142a (i.e. the first pawl structural electromotor) being mounted on electricity first In machine shell 1142b, then by pressing plate 1142c, two telescopic components 1146, nut driving section 1142e and second housing It 1147 is connected as one and (nut driving section 1142e and pressing plate 1142c to be fixed by fasteners such as screws specifically, then will One end of two telescopic components 1146 is fixed with pressing plate 1142c, and the other end of two telescopic components 1146 is then made to be directed at the Mounting hole on two shells 1147 and pass through change mounting hole (guiding)), then the centre bore of nut driving section 1142e is set in On first pawl structure lead screw 1142d, by rotating nut driving section 1142e, each component is installed in place, is finally assembled again multiple Claw 1143 and the first shell 1144, and the first shell 1144 is fixed with second housing 1147, while by fastener by the Two shells 1147 are fixed respectively at the first pawl structural electromotor, motor housing 1142b.It should be noted that erection sequence here It is intended merely to better understand the utility model, that is to say, that the erection sequence of pawl structure is not unique.
As another embodiment of pawl structure, in conjunction with the embodiment of reference attached drawing 8 and attached drawing 9 and a kind of upper pawl structure It is identical to be, the pawl structure in the present embodiment equally include driving assembly 1142, claw 1143 and multiple elastic components 1145 ( In the present embodiment, although the attached drawing table of some components and identical as a kind of upper appended drawing reference of some components of embodiment, It is not meant to imply that the structure for the component that same reference numerals represent is identical, but only represents the two and belong to one species Component), wherein driving assembly 1142 be equally for drive claw 1143 move, and driving assembly 1142 include second Pawl structural electromotor 114-5a provides power by the second pawl structural electromotor 114-5a.Certainly, in addition to the second pawl structure can be passed through Motor 114-5a is provided except power, can also provide power by the modes such as hydraulic-driven, pneumatic.
Unlike a kind of upper embodiment of pawl structure, the specific structure and elasticity of the claw 1143 in the present embodiment The position of part 1145 and effect are different with a kind of upper embodiment, certainly different from a kind of upper embodiment in addition, in the present embodiment Pawl mechanism further include claw mounting base 114-1, driving plug 114-2, guide part 114-3, for adjusting 1145 bullet of elastic component Adjustment portion 114-4 of power etc. (it should be noted that these technical characteristics are in the same technical solution it is not necessary to occur, it can To be combined according to actual needs).In addition, although the pawl structure in the present embodiment also includes anti-rotation component, in this reality It applies in example, the effect of the anti-rotation component is to prevent driving plug rotation, therefore the object of anti-rotation is different, also can be poor in structure It is different, above-mentioned each technical characteristic will be hereafter described in detail.
In conjunction with reference attached drawing 9, in a technical solution, pawl structure 114 includes claw 1143, driving assembly 1142, pawl Portion mounting base 114-1, driving plug 114-2 and multiple elastic components 1145.Claw 1143 equally can be multiple, it is also assumed that It is there are more claw structures, and claw mounting base 114-1 is the installation foundation of claw 1143.Multiple claws 1143 are arranged at pawl In portion mounting base 114-1, elastic component 1145 is provided between each claw 1143 and claw mounting base 114-1；Drive plug 114-2 is located in the accommodation space of multiple claws 1143 formation, and driving plug 114-2 is tapered equipped with matching with claw 1143 Face, the elastic component 1145 under the limitation of driving plug 114-2, between each claw 1143 and claw mounting base 114-1 always In confined state, when driving assembly 1142 drives driving plug 114-2 to travel forward, in the promotion of driving plug 114-2 Under, multiple claws 1143 inwardly move and are in tightening state；When driving assembly 1142 drives driving plug 114-2 to transport backward Under elastic force effect dynamic, in each elastic component 1145, multiple claws 1143 move out and in open configurations.Wherein, about " forward ", " backward ", the understanding of the words such as " tapered face " be explained in one embodiment, details are not described herein.
In the present embodiment, by the elastic force by elastic component 1145, (elastic component can be processed according to actual needs It is very small), and it is ingenious using driving plug and claw the tapered face to match, so as to so that the size of pawl structure as far as possible It minimizes, and then may be implemented simultaneously to operate multiple sample bottles execution switch cover, realization continuous productive process (under some operating conditions, The distance between neighboring samples bottle is very small, and pawl structure size in the prior art is larger, therefore can not realize while right The operation of Simultaneous Switching lid is carried out apart from lesser multiple sample bottles).And the pawl structure 114 in the present embodiment is in elastic component 1145 Under the action of elastic force and driving plug 114-2 are common, clamping sample bottle cap that pawl structure 114 can be very firm, it is not easy to fall.
Pawl structure in the present embodiment equally includes three kinds of states, i.e., tightening state, open configuration and between tightening shape Intermediate state between state and open configuration below will be described in detail these three states:
Assuming that initial conditions are open configuration, when needing to grab using pawl structure 114 and clamp sample bottle cap, that is, It says when pawl structure 114 being needed to be switched to tightening state from open configuration, sample bottle cap is made to be located at multiple pawls of pawl structure 114 first In the space that portion 1143 is formed, then start driving assembly 1142, under the driving of driving assembly 1142, drives plug 114-2 It travels forward, since the limitation in the tapered face in the tapered face and claw of driving plug 114-2 is (right above about tapered face Tapered face has carried out detailed explanation, and details are not described herein), during driving plug 114-2 to travel forward, drive plug 114-2, which is progressively smaller until the restraining force of elastic component 1145, is reduced to zero (i.e. driving plug 114-2 no longer squeezes spring), by It in elastic component 1145 is compressed between claw 1143 and claw mounting base 114-1, driving plug 114-2 is limited by claw 1143 Elastic component 1145 processed, therefore the elastic component 1145 compressed can discharge elastic force due to the extruding without driving plug 114-2, from And under the action of 1145 elastic force of elastic component (thrust), claw 1143 inwardly moves, the distance between two neighboring claw 1143 It is gradually reduced, during multiple 1143 inwardly movements of claw, due to driving the restriction effect of plug 114-2, moves to one Determine the distance between two neighboring claw 1143 after degree and is reduced to minimum, multiple claws 1143 are in tightening state at this time, It can be regarded as claw 1143 before this and be in intermediate state.
On the contrary, when switching from tightening state to open configuration, it is same to start driving assembly 1142, in driving assembly 1142 Driving under, driving plug 114-2 move backward (that is when switching to open configuration from tightening state, driving assembly The direction of 1142 driving force is opposite with when switching to tightening state from open configuration), it is moved backward in driving plug 114-2 In the process, since the effect (size (outer rim perimeter and inner edge perimeter) in tapered face is gradually increased at this time) in tapered face drives plug 114-2 gradually squeezes claw 1143, and claw 1143 moves out and compression elastic piece 1145, between two neighboring claw 1143 The decrement of elastic component 1145 is gradually increased, when the decrement of elastic component 1145 reaches maximum, since elastic component 1145 cannot It continues to compress again, therefore 1143 stop motion of claw, the distance between two neighboring claw 1143 reaches maximum at this time, multiple Claw is in open configuration.
About guide part 114-3, guide part 114-3 has multiple guide groove 114-3a, claw 1143 and corresponding guiding Slot 114-3a is slidably connected, and (that is the quantity of guide groove 114-3a and the quantity of claw 1143 are corresponding, for example, claw 1143 It is 4, then it is also 4 that guide groove 114-3a is corresponding), for playing the guiding role when claw 1143 inwardly and outwardly moves, Specifically, multiple claws 1143 are inwardly moved along corresponding guide groove 114-3a under the driving of driving assembly 1142, thus real The tightening state of existing claw 1143；Similarly under the driving of driving assembly 1142 (opposite when driving direction is with tightening state), and And under the effect of the elastic force of elastic component 1145, multiple claws 1143 are moved out along corresponding guide groove 114-3a, to realize The open configuration of claw 1143.
Wherein, for the shape of guide part 114-3 can there are many, can specifically be determined according to the actual situation, example If guide part 114-3 is plate-like, guide groove 114-3a is uniformly arranged along the circumferential direction of guide part 114-3.Further, for guiding Diversified forms also can be set in the formation of slot 114-3a, it is preferable that the corresponding part of guide groove 114-3a and claw 1143 (i.e. with The part that guide groove is slidably connected) shape it is mutually complementary, for example, it is " opening " " convex " font that guide groove, which is section, i.e., " convex " Word removes the horizontal line for sealing of the top, and accordingly, claw 1143 is used to set with the part cooperated guide groove 114-3a It is set to the shape that section is " convex " font, " convex " font of claw 1143 is just inserted into " opening " of guide groove 114-3a In " convex " font, and can radial direction in guide groove 114-3a along guide part 114-3 close to the center of guide part 114-3 The center movement of movement or separate guide part 114-3.
The specific structure of the claw 1143 in the present embodiment will be described in detail below:
In conjunction with shown in Fig. 9 and Figure 11, claw 1143 includes the first flat part 114-6a and rake 1143b, multiple claws Cylindric clamping part, the respective rake of multiple claws 1143 is collectively formed in 1143 respective first flat part 114-6a Tapered surface is collectively formed in the medial surface of 1143b.In the present embodiment, by the way that the inner wall of multiple claws 1143 is spelled using splicing thought It is connected in the tapered surface to match with driving plug 114-2, and being spliced to form for pressing from both sides by each first flat part 114-6a Hold the cylindric clamping part of sample bottle cap, structure is simple, it is compact, convenient for manufacture, and cylindric clamping part can be adapted for The clamping of most of bottle caps can be such that the pawl structure 114 in the utility model standardizes.
Further, each claw 1143 further includes the second flat part 114-6b, and rake 1143b is located at the first flat part Between 114-6a and the second flat part 114-6b, it is provided on the second flat part 114-6b and matches with guide groove 114-3a shape Sliding block (such as sliding block here can be claw mentioned hereinbefore " convex " shape).Wherein, sliding block is arranged It is easy to process on the second flat part 114-6b, that is, an end of claw, and matching with guide groove easy to accomplish It closes.
Further, for the ease of installation, reduce the size of pawl structure 114 as far as possible, and also to can be with pawl Portion mounting base 114-1 is preferably coupled, the first flat part 114-6a, the second flat part 114-6b and rake 1143b Outer surface be collectively formed match with claw mounting base 114-1 shape it is cylindric.
In addition, as described in a kind of upper embodiment, it is tighter in order to hold sample bottle, it is preferable that at least to exist Annular knurl or lines are provided on the inner wall of first flat part 114-6a of one claw 1143.It certainly, it is highly preferred that can be Annular knurl or lines are respectively provided on the inner wall of first flat part 114-6a of each claw 1143.
