Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tools, and specifically, to a needle tube feeding clamp. Background Art
[0002] In the production process of most products such as existing nine-needle heads and single-needle heads, a needle loading machine is required to assemble the needle tube onto the needle base. When feeding the needle loading machine at present, usually, workers use two long strip-shaped plates to shovel up the needle tubes and put them into the needle grooves of the needle loading machine (even if the two long strip-shaped plates are in a V shape). However, since the needle tubes are relatively small and the number of shoveled-up each time is large (generally about tens of thousands), and it is easy for the needle tubes to fall due to hand shaking, uneven holding of the plates or gaps left between the plates when the workers control the two long strip-shaped plates to shovel up the needle tubes, resulting in contamination of the needle tubes. In addition, the needle loading machine needs to be in a stopped state during the needle tube feeding process. Therefore, the existing method of feeding the needle loading machine by shoveling up the needle tubes with two long strip-shaped plates also has the disadvantages of low feeding efficiency, and moreover, the feeding operation is troublesome. Summary of the Invention
[0003] The main purpose of the utility model is to provide a needle tube feeding clamp that is easy to operate and feed.
[0004] To achieve the main purpose of the utility model, the utility model provides a needle tube feeding clamp, which includes two clamping arms. The fixed ends of the two clamping arms are connected to each other. A needle blocking plate is provided at the movable end of at least one clamping arm. The two clamping arms can approach each other or separate from each other. When the two clamping arms approach each other, a needle tube accommodating groove is formed between the two clamping arms and the needle blocking plate. Both clamping arms are in a plate shape. Each clamping arm has a holding section, a bending section, and a baffle section. The first ends of the holding sections of the two clamping arms are connected to each other. The bending section extends from the second end of the holding section away from the other clamping arm. The baffle section extends obliquely from the protruding end of the bending section towards the other clamping arm. The needle blocking plate is provided on the baffle section and is located on one side of the baffle section. The first included angle between the baffle sections of the two clamping arms is an acute angle.
[0005] As can be seen from the above, when it is necessary to feed the needle loading machine with needle tubes, insert the needle tube feeding clamp into the needle tube preparation area and control the two clamping arms to approach each other, so that the needle tubes enter the needle tube accommodating groove formed between the two clamping arms and the needle blocking plate. Due to the structural design of the needle tube feeding clamp, it is not easy for gaps to appear at the movable ends of the clamping arms after approaching, thus effectively avoiding the falling of the needle tubes. When the needle tube feeding clamp moves to the needle groove of the needle loading machine with the loaded needle tubes, control the two clamping arms to separate from each other, so that the needle tubes fall into the needle groove through the gaps between the movable ends of the two clamping arms and / or the gaps between the clamping arms and the needle blocking plate (or the gaps between the needle blocking plates), so as to realize rapid feeding of the needle loading machine and make the feeding of the needle tubes simpler and easier to operate. And setting the clamping arms in a bent shape is beneficial to expanding the accommodation capacity of the needle tube accommodating groove, so as to reduce the number of single-round feeding of the needle groove of the needle loading machine.
[0006] In a preferred embodiment, the second angle between the holding segments of the two clamping arms is an acute angle; the third angle between the holding segment and the bending segment is an obtuse angle.
[0007] As can be seen from the above, this design can further increase the capacity of the syringe barrel receiving groove and optimize the structure of the clamping arms to make it more reasonable.
[0008] In another preferred embodiment, a locking block is provided on the holding segment, and the locking block is arranged close to the bending segment.
[0009] As can be seen from the above, providing the locking block on the holding segment facilitates the operator to control the two clamping arms to move closer to each other or move away from each other.
[0010] In a further embodiment, the locking block has a straight plate segment and an arc plate segment. The straight plate segment extends from the holding segment away from the other clamping arm, and the arc plate segment is located on the side of the straight plate segment close to the bending segment. The arc plate segment is concave into the fourth angle between the straight plate segment and the holding segment.
[0011] As can be seen from the above, the above structural design of the locking block is beneficial for the operator to better control the movement of the clamping arms through the locking block.
[0012] In a further preferred embodiment, a needle blocking plate is provided on one of the two clamping arms; the needle blocking plate is trapezoidal, the upper base of the trapezoid is located at the extending end of the baffle segment, or the extending end of the baffle segment is located between the upper base and the lower base of the trapezoid, the lower base of the trapezoid is arranged close to the bending segment, one waist of the trapezoid is connected to the baffle segment, or the needle blocking plate is in the shape of a first triangle, one side of the first triangle is connected to the baffle segment and one end of this side is located at the extending end of the baffle segment, and the first triangle extends towards the other clamping arm.
[0013] As can be seen from the above, this design can not only prevent a gap from appearing between the needle blocking plate and the movable ends of the two clamping arms when the two clamping arms move closer, thereby preventing the syringe barrel from falling; but also optimize the shape of the needle blocking plate and avoid the needle blocking plate from being too large, making the operation of the syringe barrel loading clamp highly flexible; at the same time, the structure of the needle blocking plate can also be diverse.
[0014] In a further preferred embodiment, needle blocking plates are provided on both clamping arms. The needle blocking plates are in the shape of second triangles. The first sides of the second triangles are connected to the baffle segments. When the two clamping arms move closer, the second sides of the two second triangles are joined together to form a third triangle, and the movable ends of the two baffle segments are combined with each other.
[0015] As can be seen from the above, this design can not only prevent a gap from appearing between the movable ends of the two clamping arms and between the two needle blocking plates when the two clamping arms move closer, thereby preventing the syringe barrel from falling; but also optimize the shape of the needle blocking plates and avoid the needle blocking plates from being too large, making the operation of the syringe barrel loading clamp highly flexible.
[0016] A further solution is that a serrated structure is provided on the second side of the second triangle, and the serrated structures on the second sides of the two second triangles are meshed with each other.
[0017] As can be seen from the above, setting the serrated structure on the needle stop plate can improve the reliability and accuracy of the combination between the two needle stop plates, and avoid the occurrence of gaps between the two clamping arms and between the two needle stop plates due to misalignment.
[0018] Another preferred solution is that an arc-shaped connecting portion is connected between the fixed ends of the two clamping arms, and the arc-shaped connecting portion can be elastically deformed; or a hinge is connected between the fixed ends of the two clamping arms.
[0019] As can be seen from the above, connecting the two clamping arms through the arc-shaped connecting portion is beneficial to simplifying the structure of the syringe feeding clip, making the production of the syringe feeding clip more convenient and with lower cost; while connecting the two clamping arms with a hinge is beneficial to better extending the service life of the syringe feeding clip.
[0020] A further solution is that the syringe feeding clip is made of stainless steel, aluminum alloy or plastic.
[0021] As can be seen from the above, the syringe feeding clip made of stainless steel, aluminum alloy or plastic has the advantages of meeting the use requirements in terms of structural strength, light weight, long service life, and convenient production. Brief Description of the Drawings

[0027] The present utility model will be further described below in conjunction with the drawings and embodiments. Detailed Embodiment
[0028] First Embodiment of the Syringe Feeding Clip
[0029] Refer to Figure 1, the syringe loading clip 100 includes two clamping arms 1, and the fixed ends of the two clamping arms 1 are connected to each other. In order to simplify the structure of the syringe loading clip 100, facilitate the production of the syringe loading clip 100, and reduce the production cost and production difficulty, in this embodiment, the fixed ends of the two clamping arms 1 are preferably connected by an arc-shaped connecting portion 2, and the arc-shaped connecting portion 2 can be elastically deformed, so that the two clamping arms 1 can approach or move away from each other; preferably, the two clamping arms 1 and the arc-shaped connecting portion 2 are integrally formed; of course, as another alternative solution, in another embodiment, a hinge can also be used to connect the fixed ends of the two clamping arms 1, and using a hinge to connect the two clamping arms 1 is beneficial to better extend the service life of the syringe loading clip 100; as still another alternative solution, in still another embodiment, the fixed ends of the two clamping arms 1 can also be directly connected together.
[0030] Combined with Figures 2 to 4 , a needle blocking plate 3 is provided at the movable end of at least one clamping arm 1, and when the two clamping arms 1 approach each other, a syringe receiving groove 10 is formed between the two clamping arms 1 and the needle blocking plate 3 for loading and unloading syringes.
[0031] Preferably, the two clamping arms 1 are both plate-shaped, and the clamping arm 1 has a holding section 11, a bending section 12, and a baffle section 13. Among them, the first ends (i.e., the fixed ends of the clamping arm 1) of the holding sections 11 of the two clamping arms 1 are connected to each other (i.e., connected by the arc-shaped connecting portion 2, or connected by a hinge, or the first ends of the two holding sections 11 are directly connected, etc.), and the second included angle b between the holding sections 11 of the two clamping arms 1 is preferably an acute angle; the bending section 12 extends from the second end of the holding section 11 away from the other clamping arm 1, and the third included angle c between the bending section 12 and the holding section 11 is preferably an obtuse angle; the baffle section 13 extends obliquely from the protruding end of the bending section 12 toward the other clamping arm 1, and the first included angle a between the baffle sections 13 of the two clamping arms 1 is preferably an acute angle; setting the clamping arm 1 in a bent shape is beneficial to increasing the accommodation capacity of the syringe receiving groove 10 to reduce the number of times of single-round feeding of the needle slots of the syringe loading machine.
[0032] In addition, in this embodiment, only one of the two clamping arms 1 is provided with a stop pin plate 3. The stop pin plate 3 is preferably arranged on the baffle section 13 and located on one side of the width of the baffle section 13. Among them, the stop pin plate 3 is preferably trapezoidal, the upper base of the trapezoid is located at the extending end of the baffle section 13, the lower base of the trapezoid is arranged close to the bending section 12, and one waist of the trapezoid is connected to the baffle section 13. Of course, as another alternative solution, in other embodiments, the extending end of the baffle section 13 can also be located between the upper base and the lower base of the trapezoid. This design can not only prevent a gap from appearing between the stop pin plate 3 and the movable ends of the two clamping arms 1 when the two clamping arms 1 approach each other, thus preventing the syringe from falling; but also optimize the shape of the stop pin plate 3 and avoid the stop pin plate 3 being too large, making the operation of the syringe loading clamp 100 highly flexible; at the same time, the structure of the stop pin plate 3 can also be diverse. Of course, as another alternative solution, in other embodiments, when only one of the two clamping arms 1 is provided with a stop pin plate 3, the stop pin plate 3 can also be in the shape of a first triangle. One side of the first triangle is connected to the baffle section 13, and one end of this side is located at the extending end of the baffle section 13. The first triangle extends towards the other clamping arm 1, that is, it can be regarded that the base of the first triangle is connected to the baffle section 13, and the apex angle of the first triangle extends towards the other clamping arm 1.
[0033] Furthermore, a clamping block 4 is preferably arranged on the holding section 11, and the clamping block 4 is arranged close to the bending section 12. Among them, the clamping block 4 preferably has a straight plate section 41 and an arc plate section 42. The straight plate section 41 extends from the holding section 11 away from the other clamping arm 1, and the arc plate section 42 is located on the side of the straight plate section 41 close to the bending section 12, and the arc plate section 42 is concave towards the fourth included angle d between the straight plate section 41 and the holding section 11. By arranging the clamping block 4, it is more convenient for the operator to control the approach or separation of the two clamping arms 1, and the structural design of the clamping block 4 is beneficial for the operator to better control the movement of the clamping arm 1 through the clamping block 4. Preferably, the number of clamping blocks 4 on each holding section 11 is two, and the two clamping blocks 4 are distributed along the extending direction of the holding section 11.
[0034] In this embodiment, the syringe feeding clamp 100 is preferably made of stainless steel. As a first preferred solution, the two clamping arms 1, the arc-shaped connecting portion 2, and the needle blocking plate 3 are integrally formed by a stamping process, and the clamping block 4 is fixedly welded to the holding section 11 of the clamping arm 1 by a welding process; as another preferred solution, the two clamping arms 1 and the arc-shaped connecting portion 2 can also be integrally formed by a stamping process, and the needle blocking plate 3 is fixedly welded to the holding section 11 by a welding process, and the clamping block 4 is fixedly welded to the holding section 11 of the clamping arm 1 by a welding process. Making the syringe feeding clamp 100 with stainless steel enables the structural strength of the syringe feeding clamp 100 to meet the usage requirements, and it has the advantages of light weight, long service life, and convenient production. Of course, as another alternative solution, in another embodiment, the syringe feeding clamp 100 can also be made of aluminum alloy, and the manufacturing method of the syringe feeding clamp 100 made of aluminum alloy can refer to the manufacturing method of the syringe feeding clamp 100 made of stainless steel described above; as still another alternative solution, in still another embodiment, the syringe feeding clamp 100 can also be made of plastic by an injection molding process, and when the syringe feeding clamp 100 is produced by an injection molding process, the entire syringe feeding clamp 100 can be integrally formed, that is, the two clamping arms 1, the arc-shaped connecting portion 2, the needle blocking plate 3, and the clamping block 4 are integrally formed.
[0035] When the syringe feeding of the syringe loading machine is required, the syringe feeding clamp 100 is inserted into the syringe preparation area and the two clamping arms 1 are controlled to close and fit, so that the syringe enters the syringe receiving groove 10 formed between the two clamping arms 1 and the needle blocking plate 3. Due to the structural design of the syringe feeding clamp 100, the movable ends of the clamping arms 1 are not likely to have gaps after closing, thereby effectively preventing the syringe from falling; when the syringe feeding clamp 100 moves to the needle slot of the syringe loading machine with the syringe loaded and unloaded, the two clamping arms 1 are controlled to separate, so that the syringe falls into the needle slot through the gap between the movable ends of the two clamping arms 1 and / or the gap between the clamping arm 1 and the needle blocking plate 3.
[0036] In summary, through the structural design of the syringe feeding clamp 100, the syringe feeding clamp 100 can perform rapid feeding of the syringe loading machine, and the feeding operation is simpler and more convenient, which is beneficial to improving production efficiency and preventing the syringe from falling.
[0037] Second Embodiment of Syringe Feeding Clamp
[0038] Refer to Figure 5 , the difference between this embodiment and the first embodiment of the syringe feeding clamp lies in the setting of the needle blocking plate 6. Specifically, in this embodiment:
[0039] Both clamping arms 5 are provided with stop pin plates 6. The stop pin plate 6 is in the shape of a second triangle, and the first side of the second triangle is connected to the baffle section 51. When the two clamping arms 5 approach each other, the second sides of the two second triangles are joined to each other, so that the two second triangles form a third triangle, and the movable ends of the two baffle sections 51 are combined with each other. This design can not only prevent gaps from appearing between the movable ends of the two clamping arms 5 and between the two stop pin plates 6 when the two clamping arms 5 approach each other, thereby preventing the syringe from falling; but also optimize the shape of the stop pin plate 6 and avoid the stop pin plate 6 from being too large, making the syringe loading and clamping operation highly flexible.
[0040] Preferably, a serrated structure 61 is provided on the second side of the second triangle, and the serrated structures 61 on the second sides of the two second triangles are engaged with each other. By providing the serrated structure 61 on the stop pin plate 6, the reliability and accuracy of the combination between the two stop pin plates 6 can be improved, and gaps caused by misalignment between the two clamping arms and between the two stop pin plates 6 can be avoided, thereby preventing the syringe from falling.
[0041] Finally, it should be emphasized that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
