Abstract
Description
Technical Field
[0001] This utility model relates to the field of acupuncture needle production, and more specifically, to an acupuncture needle production clamping device. Background Technology
[0002] Acupuncture needles are a common type of acupuncture needle used in traditional Chinese medicine. They are generally composed of two parts: a needle body and a needle handle, which are fixedly connected. The front end of the needle body forms the needle tip. The needle body is generally formed by cutting a section of thread. A bend is set at the rear end of the needle handle to connect with the handle. The needle handle generally adopts a spring-loaded structure to facilitate the operation of the acupuncturist.
[0003] Currently, clamping devices are required when processing acupuncture needles. Existing clamping devices can usually only stably clamp acupuncture needles of a single specification. As a result, during the production process, due to the different specifications of acupuncture needles, the clamping device cannot stably clamp acupuncture needles of different diameters, which easily leads to insecure clamping and affects the production quality of acupuncture needles, thus making the clamping device have certain limitations. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides an acupuncture needle production clamping device, which aims to improve the problem that existing clamping devices can usually only stably clamp acupuncture needles of a single specification. This results in the clamping device being unable to stably clamp acupuncture needles of different diameters during the production process due to the different specifications of acupuncture needles.
[0005] This utility model is implemented as follows:
[0006] This utility model provides an acupuncture needle production clamping device, including a base, a clamping component, and a replacement component.
[0007] The upper surface of the base is connected to a bracket, and a placement plate is inserted into the surface of the base. The clamping assembly includes a driving component and a mounting base. The driving component is mounted on the top of the bracket, and the mounting base is threaded onto the movable end of the driving component. The mounting base is slidably disposed within the bracket. A positioning plate is inserted into the lower surface of the mounting base. Placement grooves are formed on the surfaces of both the positioning plate and the placement plate. The replacement assembly includes a transmission component and a double-ended screw. Both the transmission component and the double-ended screw are rotatably connected within the mounting base, and one end of the transmission component is drively connected to the double-ended screw. Positioning rods are threaded onto the surfaces of the two threaded sections of the double-ended screw. Two inserts are connected to the top of the positioning plate, and the positioning rods are inserted into the inserts.
[0008] In one embodiment of this utility model, a connecting shaft is rotatably connected inside the base, and a first lead screw and a handwheel are respectively connected to both ends of the connecting shaft. A movable block is threaded onto the surface of the first lead screw, and a connecting frame is connected to the lower surface of the placement plate. The movable block is inserted into the connecting frame.
[0009] In one embodiment of this utility model, the base has a receiving cavity, the first lead screw is located in the receiving cavity, and the movable block is in contact with the inner wall of the receiving cavity.
[0010] In one embodiment of the present invention, the driving component includes a motor and a second lead screw. The motor is mounted on the top of the bracket, and the output shaft of the motor is connected to the second lead screw. An internal threaded cylinder is connected to the top of the mounting base, and the internal threaded cylinder is threaded onto the surface of the second lead screw.
[0011] In one embodiment of this utility model, the bracket is U-shaped, and protrusions are connected to both sides of the mounting base. A limiting groove corresponding to the protrusion is opened on the side of the bracket, and a guide rod is connected in the limiting groove. The protrusion is slidably sleeved on the surface of the guide rod.
[0012] In one embodiment of this utility model, the transmission component includes a rotating rod, a knob, and a first bevel gear. The rotating rod is rotatably connected to the mounting base and is connected to the knob and the first bevel gear respectively. The first bevel gear is connected to the double-ended screw drive.
[0013] In one embodiment of this utility model, a second bevel gear is connected to the surface of the double-ended screw, the second bevel gear meshes with the first bevel gear, and a cavity is provided in the mounting base, in which both the first bevel gear and the second bevel gear are located.
[0014] In one embodiment of this utility model, one end of the positioning rod is connected to a movable block, and the movable block is threaded onto the surface of the threaded section of the double-ended screw.
[0015] In one embodiment of this utility model, a sliding groove is provided in the mounting base, and the moving block is in contact with the inner wall of the sliding groove.
[0016] The beneficial effects of this utility model are as follows: The acupuncture needle production clamping device obtained by the above design allows for easy replacement of the placement plate from the base during use, based on the diameter of the acupuncture needle. Through the cooperation of the transmission component and the double-ended screw, two positioning rods move relative to each other within the mounting base. The two positioning rods are then pulled out from their corresponding inserts, allowing the inserts and positioning plates to be removed from the mounting base. The positioning plates can then be replaced according to the diameter of the acupuncture needle, reducing the possibility that the clamping device cannot stably clamp acupuncture needles of different diameters. The acupuncture needle is placed in the placement slot on the placement plate, and then the drive component on the bracket, in cooperation with the mounting base, moves the mounting base downwards, causing the positioning plate and placement plate to clamp the acupuncture needle. This facilitates the clamping and fixing of the acupuncture needle during the production process. Attached Figure Description

Detailed Implementation
[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0025] Example
[0026] Please see Figures 1-5 This utility model provides an acupuncture needle production clamping device, including a base 100, a clamping component 200 and a replacement component 300.
[0027] The clamping component 200 is mounted on the bracket 110 of the base 100, and the replacement component 300 is mounted on the clamping component 200. By replacing the component 300, the positioning plate 230 can be removed from the mounting base 220 for replacement, reducing the possibility that the clamping device cannot stably clamp acupuncture needles of different diameters.
[0028] Please see Figure 1 A bracket 110 is connected to the upper surface of the base 100, and a placement plate 120 is inserted into the surface of the base 100.
[0029] In this embodiment, a connecting shaft 130 is rotatably connected inside the base 100. A first lead screw 131 and a handwheel 132 are respectively connected to both ends of the connecting shaft 130. A movable block 140 is threaded onto the surface of the first lead screw 131. A connecting frame 121 is connected to the lower surface of the placement plate 120, and the movable block 140 is inserted into the connecting frame 121. In specific implementation, rotating the handwheel 132 can drive the connecting shaft 130 and the first lead screw 131 to rotate, thereby causing the movable block 140 to move along the inner wall of the receiving cavity 150, which facilitates the stability of the movable block 140 during movement. The movable block 140 can be pulled out from the connecting frame 121, which can be pulled out from the base 100, thereby replacing the placement plate 120. The diameter of the placement groove 240 on each placement plate 120 is different. The placement plate 120 is replaced according to the different diameter acupuncture needles, so that the acupuncture needles fit tightly against the inner wall of the placement groove 240 on the placement plate 120, which is conducive to the stability of the acupuncture needles in the placement groove 240. The base 100 has a receiving cavity 150, the first lead screw 131 is located in the receiving cavity 150, and the movable block 140 fits against the inner wall of the receiving cavity 150.
[0030] Please see Figures 1-4 The clamping assembly 200 includes a drive component 210 and a mounting base 220. The drive component 210 is mounted on the top of the bracket 110. The mounting base 220 is threaded onto the movable end of the drive component 210 and is slidably disposed within the bracket 110. A positioning plate 230 is inserted into the lower surface of the mounting base 220. Both the positioning plate 230 and the placement plate 120 have placement grooves 240 on their surfaces. In practice, the acupuncture needle is placed in the placement groove 240 of the placement plate 120. By activating the drive component 210, its movable end is driven... The movable mounting base 220 moves downward along the inside of the bracket 110, which in turn drives the positioning plate 230 to move downward. The positioning plate 230 then comes into contact with the upper surface of the placement plate 120. At this time, the placement groove 240 on the positioning plate 230 and the placement groove 240 on the placement plate 120 have the same diameter, and the positioning plate 230 presses down on the acupuncture needle on the placement plate 120. The acupuncture needle is located in the two placement grooves 240. The clamping of the positioning plate 230 and the placement plate 120 facilitates the clamping and fixing of the acupuncture needle during the production process.
[0031] In this embodiment, the driving component 210 includes a motor 211 and a second lead screw 212. The motor 211 is mounted on the top of the bracket 110, and the output shaft of the motor 211 is connected to the second lead screw 212. An internally threaded cylinder 221 is connected to the top of the mounting base 220, and the internally threaded cylinder 221 is threadedly sleeved on the surface of the second lead screw 212. The bracket 110 is U-shaped, and protrusions 222 are connected to both sides of the mounting base 220. A limiting groove 111 corresponding to the protrusion 222 is opened on the side of the bracket 110. A guide rod 160 is connected in the limiting groove 111, and the protrusion 222 is slidably sleeved on the guide rod. On the 160 surface, in specific implementation, by starting the motor 211, its output shaft drives the second lead screw 212 to rotate. Since the protrusions 222 on both sides of the mounting base 220 are slidably sleeved on the surface of the guide rod 160, the internal threaded cylinder 221 and the mounting base 220 can move up and down, which helps to improve the stability of the mounting base 220 and the positioning plate 230 during the movement. The protrusions 222 will move up and down along the inner wall of the limiting groove 111. The moving distance of the protrusions 222 can be limited by the limiting groove 111, which can reduce the possibility of the internal threaded cylinder 221 falling off the second lead screw 212.
[0032] Please see Figures 1-5 The replacement component 300 includes a transmission component 310 and a double-ended screw 320. Both the transmission component 310 and the double-ended screw 320 are rotatably connected within the mounting base 220, with one end of the transmission component 310 being drively connected to the double-ended screw 320. Positioning rods 330 are threadedly fitted onto the surfaces of both threaded sections of the double-ended screw 320. Two inserts 250 are connected to the top of the positioning plate 230, and the positioning rods 330 are inserted into the inserts 250. In practical implementation, the transmission component 310 is rotated to move the screw. Rotating the double-ended screw 320 causes the two positioning rods 330 to move relative to each other within the mounting base 220. The two positioning rods 330 are then pulled out from their corresponding inserts 250, no longer restricting the inserts 250. The inserts 250 can then be removed from the mounting base 220, making it easier to remove the positioning plate 230. The positioning plate 230 can then be replaced according to the diameter of the acupuncture needles currently being produced, reducing the possibility that the clamping device cannot stably clamp acupuncture needles of different diameters.
[0033] In this embodiment, the transmission component 310 includes a rotating rod 311, a knob 312, and a first bevel gear 313. The rotating rod 311 is rotatably connected within the mounting base 220, and is connected to both the knob 312 and the first bevel gear 313. The first bevel gear 313 is connected to a double-ended screw 320. A second bevel gear 321 is connected to the surface of the double-ended screw 320, and the second bevel gear 321 meshes with the first bevel gear 313. A cavity 223 is provided within the mounting base 220, and both the first bevel gear 313 and the second bevel gear 321 are located within the cavity 223. In specific implementation, the knob 312 is rotated... The rotating rod 311 and the first bevel gear 313 can be rotated. The first bevel gear 313 will drive the second bevel gear 321 and the double-ended screw 320 to rotate. The double-ended screw 320 will drive the two positioning rods 330 to move relative to each other or in opposite directions, which makes it easy to pull the insert 250 out of the mounting base 220 or fix the insert 250 in the mounting base 220. It is also convenient to disassemble and replace the positioning plate 230 according to the diameter of different acupuncture needles. The first bevel gear 313 and the second bevel gear 321 are both set in the cavity 223, which reduces the possibility of the first bevel gear 313 and the second bevel gear 321 being easily worn due to external influences.
[0034] One end of the positioning rod 330 is connected to a movable block 331, which is threaded onto the threaded section of the double-ended screw 320. A groove 224 is provided inside the mounting base 220, and the movable block 331 fits against the inner wall of the groove 224. In specific implementation, when the double-ended screw 320 rotates, the movable block 331 can move along the inner wall of the groove 224, reducing the possibility that the movement trajectory of the movable block 331 and the positioning rod 330 will deviate during the movement.
[0035] Specifically, the working principle of this acupuncture needle production clamping device is as follows: During use, rotating the handwheel 132 rotates the connecting shaft 130 and the first lead screw 131, thereby causing the movable block 140 to move along the inner wall of the receiving cavity 150. The movable block 140 will then be pulled out from the connecting frame 121, allowing the connecting frame 121 and the placement plate 120 to be removed from the base 100. This facilitates the replacement of the placement plate 120 according to the diameter of the acupuncture needle. Then, rotating the knob 312 rotates the rotating rod 311 and the first bevel gear 313. The first bevel gear 313 drives the second bevel gear 321 and the double-ended screw 320 to rotate, thereby causing the two moving blocks 331 to move relative to each other along the inner wall of the slide groove 224. The rod 330 will be pulled out from the corresponding insert 250, making it easy to remove the insert 250 and the positioning plate 230 from the mounting base 220. The positioning plate 230 can be replaced according to the diameter of the acupuncture needle, reducing the possibility that the clamping device cannot stably clamp acupuncture needles of different diameters. The acupuncture needle is placed in the placement slot 240 on the placement plate 120. By starting the motor 211 on the bracket 110, its output shaft drives the second lead screw 212 to rotate, thereby driving the internal threaded cylinder 221 and the mounting base 220 to move downward, so that the positioning plate 230 is in contact with the upper surface of the placement plate 120. The acupuncture needle can be clamped by the positioning plate 230 and the placement plate 120, which is beneficial for clamping and fixing the acupuncture needle during the production process.
[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
