Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of syringe automatic liquid pushing, and particularly relates to a syringe clamping device. BACKGROUND

[0002] In order to improve the accuracy of injection operation, in many application scenarios, injection robots have become indispensable tools, especially in facial injection surgery in the field of medical cosmetology. In these delicate operations, injection robots often work with syringe clamping mechanisms to ensure that the needle can achieve accurate navigation and positioning during injection, thereby significantly improving the accuracy of injection.

[0003] At present, a drill chuck is commonly used in the market to fix the drill bit, the inside of which realizes self-centering function by using a conical surface thread, and the outside is locked by a small gear. The small gear is coupled with a ring gear to drive the conical surface thread pair in the drill chuck to move, thereby completing the clamping process of the drill bit.

[0004] However, the drill chuck structure has some limitations when clamping the syringe. The syringe is usually equipped with a syringe handle, and the shape of this part is often irregular and has a large size. Although the main body diameter of the syringe may be small (for example, 10 mm), in order to ensure that the entire syringe can be clamped, the hole on the drill chuck needs to be made large (the diameter may reach 30 mm). This not only causes waste of materials, but also brings inconvenience to the operation of medical personnel, and also increases the volume of the end of the medical injection robot.

[0005] In addition, the drill chuck structure requires that the object must be placed along the axis, which is not convenient for operation for medical devices such as syringes with irregular shapes. At the same time, the drill chuck structure also needs a small gear to clamp or loosen the part, which is not only difficult to place properly, but also easy to lose and interfere with normal work.

[0037] In order to enable the above-mentioned purposes, features and advantages of the present application to be more clearly understood, the following will further describe the present application. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0038] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be practiced without the specific details described herein; obviously, the embodiments described in the specification are only a part of the embodiments of the present application, not all the embodiments.

[0039] The syringe clamping device of the present application embodiment is described below in conjunction with the drawings.

[0040] The syringe clamping device provided by the present application embodiment can be applied to an injection robot to ensure the axial stability of the syringe during injection.

[0041] As shown in Figure 1 The syringe clamping device of the present application embodiment can include a base 1, two clamping blocks 2 and a pushing mechanism 3.

[0042] The base 1 is provided with a plurality of wedge-shaped grooves 10.

[0043] The two clamping blocks 2 are symmetrically arranged along the horizontal center axis of the base 1, and the two clamping blocks 2 are slidingly arranged on the base 1 along the width direction of the base 1.

[0044] In some embodiments, as shown in Figure 1 The base 1 is provided with a first sliding rail 4, wherein the first sliding rail 4 is arranged along the width direction of the base 1, and the clamping block 2 is slidingly connected to the first sliding rail 4, that is, the clamping block 2 is provided with a second sliding groove matched with the first sliding rail 4, and the second sliding groove is matched with the first sliding rail 4 to realize the sliding connection of the clamping block 2 to the first sliding rail 4, wherein the first sliding rail 4 can adopt the form of a dovetail groove, which effectively prevents accidental falling or shaking of the clamping block 2 during sliding, and ensures the stability of the clamping block 2 slidingly connected to the first sliding rail 4.

[0045] Referring to Figure 1 and Figure 2The pushing mechanism 3 includes a push block 30 and a locking handle 31. The push block 30 has a U-shaped opening 300 facing the clamping block 2. At least one end of the two clamping blocks 2 is located in the U-shaped opening 300. The push block 30 has a first U-shaped groove 301 for longitudinal placement of the syringe 100. The first U-shaped groove 301 is connected to the U-shaped opening 300. That is, by setting the first U-shaped groove 301, the syringe 100 can be placed longitudinally on the push block 30. This design not only allows the syringe 100 to be easily placed between the two clamping blocks 2, but also effectively avoids the inconvenience caused by traditional axial installation and greatly improves the installation efficiency.

[0046] The clamping block 2 and the push block 30 each have an inclined surface 302 with the same inclination angle on their mating surfaces. The push block 30 is slidably disposed on the base 1 along the length of the base 1 to drive the two clamping blocks 2 to move closer together to clamp the syringe 100. That is, in order to achieve the sliding placement of the push block 30 on the base 1, in some embodiments, it can be referred to Figure 1 and Figure 6 As shown, a second slide rail 5 is provided on the base 1. The second slide rail 5 is arranged along the length direction of the base 1. The push block 30 is slidably connected to the second slide rail 5. The stability of the push block 30 when sliding can be ensured by providing a second slide groove on the push block 30 that is compatible with the second slide rail 5 and using the second slide groove in conjunction with the second slide rail 5.

[0047] It should be noted that the inclined surface 302 can be inclined from the clamping block 2 toward the pushing block 30, or from the pushing block 30 toward the clamping block 2. The inclination direction of the inclined surface 302 can be selected according to the actual situation.

[0048] For example, refer to Figure 1 For example, the inclined surface 302 is oriented so that the clamping block 2 is inclined towards the push block 30. In actual operation, after the operator places the syringe 100 in the first U-shaped groove 301 and ensures that it is positioned between the two clamping blocks 2, the push block 30 can be smoothly pushed towards the clamping blocks 2 to perform the clamping operation. During this process, the two inclined surfaces 302 contact to achieve force transmission. As the push block 30 is continuously pushed in, the two clamping blocks 2 will be driven by this pushing force, gradually moving closer to each other and finally firmly clamping the syringe 100.

[0049] Furthermore, such as Figure 3 As shown, the inclined surface 302 and the side surface of the clamping block 2 adjacent to the syringe 100 have an angle. The size of this angle directly determines the degree of inclination of the inclined surface 302, which in turn affects the effective thrust generated when pushing the push block 30 and the required sliding distance.

[0050] In order to optimize the clamping effect, the clamping block 2 with an included angle of 25 degrees can be used as a standard configuration, which has shown good clamping performance and convenient operation in practical application. However, with the continuous expansion and upgrading of product lines, clamping blocks 2 with included angles of 30 degrees, 35 degrees, 40 degrees, etc. can be selected, which can be selected according to actual conditions to meet the diversified needs of different specifications and models of syringes 100 in clamping, further improving the application range.

[0051] One end of the locking handle 31 is hinged to the push block 30, and the locking handle 31 can rotate relative to the push block 30 to insert the other end of the locking handle 31 into the corresponding wedge-shaped groove 10 to fix the position of the push block 30, or to make the other end of the locking handle 31 out of the wedge-shaped groove 10 to release the position fixing of the push block 30.

[0052] It should be noted that the wedge-shaped groove 10 can be observed from above the base 1 as shown in Figure 6 When one end of the locking handle 31 starts to rotate and enters the wedge-shaped groove 10, as the insertion depth gradually increases, the insertion end of the locking handle 31 will be subjected to more and more clamping force due to the gradually narrowing groove wall of the wedge-shaped groove 10, ensuring that once the insertion end of the locking handle 31 is inserted to a certain depth, it will be firmly fixed in the wedge-shaped groove 10, thereby achieving effective fixation of the locking handle 31 and ensuring the position stability of the push block 30 after moving to the position. Improve the convenience of user operation, and by hinging one end of the locking handle 31 to the push block 30, the locking handle 31 will not be lost.

[0053] Further, in order to improve the stability of the wedge-shaped groove 10 when fixing the locking handle 31, the design of the wedge-shaped groove 10 is further optimized. Specifically, the two groove walls of the wedge-shaped groove 10 arranged along the width direction can be designed as inclined surfaces gradually approaching each other and inclined from bottom to top. The selection of the inclination angle has certain flexibility and can be determined according to actual conditions and specific needs. For example, the inclination angle can be set to 3 degrees, 4 degrees or 5 degrees, etc. These angles can improve the fixing stability of the locking handle 31 in the wedge-shaped groove 10 to a certain extent. Through reasonable inclination design, when the locking handle 31 rotates and penetrates into the wedge-shaped groove 10, the groove wall will exert greater clamping force on the locking handle 31, thereby effectively improving the stability of the locking handle 31 when fixed.

[0054] Specifically, when actually clamping and fixing the syringes 100 of different sizes, first, the operator places the syringe 100 in the first U-shaped groove 301 and ensures that it is located between the two clamping blocks 2, and then the clamping operation can be performed by smoothly pushing the push block 30 in the direction of the clamping block 2, that is, the clamping operation of the syringe 100 can be easily realized, and then the position of the push block 30 can be fixed by rotating the locking handle 31 to correspondingly wedge-shaped slot 10, so as to realize the fixation of the syringe 100.

[0055] Compared with the traditional drill chuck structure, the design discards the cumbersome steps of axial installation, and does not need to make structural adjustment due to the difference of the syringe handle, which undoubtedly greatly reduces the production cost. At the same time, the device has simple and compact structure, adopts longitudinal placement mode, so that the installation process is more rapid and convenient. Also avoids the situation that the equipment cannot work normally due to the loss of pinion, further improves the reliability of the device.

[0056] In an embodiment of the present application, as shown in Figure 4 and Figure 5 The pushing mechanism 3 further comprises two connecting pieces 32, each connecting piece 32 corresponding to one clamping block 2, and the connecting piece 32 comprising a sliding block 320 and a pin shaft 321.

[0057] The first sliding groove 20 is arranged on the inclined surface 302 of the push block 30, and the mounting hole 303 is arranged on the inclined surface 302 of the clamping block 2, one end of the sliding block 320 is slidably arranged in the first sliding groove 20, and the other end of the sliding block 320 is hingedly connected in the mounting hole 303 through the pin shaft 321.

[0058] Specifically, the connecting piece 32 is arranged to connect the push block 30 and the clamping block 2, the connecting piece 32 is arranged to constrain the push block 30 and the clamping block 2, to ensure the stability of the movement, and to avoid the loss, and when the push block 30 moves, the pin shaft 321 cooperates with the sliding block 320 to drive the two clamping blocks 2 to move synchronously, to ensure the axiality when clamping the syringe 100, so as to avoid the inclination when clamping the syringe 100.

[0059] In an embodiment of the present application, as shown in Figure 2 and Figure 4As shown, the locking handle 31 comprises a locking block 310 and a handle 311, wherein the push block 30 is provided with a vertical slot 304, one end of the locking block 310 is hinged in the vertical slot 304, the other end of the locking block 310 is rotatably inserted into the wedge-shaped slot 10, the push block 30 is provided with an avoiding slot 305 between the base 1, one end of the handle 311 is hinged on the locking block 310, and when the one end of the locking block 310 is locked and inserted into the wedge-shaped slot 10, the handle 311 is located in the avoiding slot 305.

[0060] Specifically, by pulling the handle 311, the locking block 310 can be rotated with the hinged point of the locking block 310 in the vertical slot 304 as the center, when the one end of the locking block 310 away from the vertical slot 304 is inserted into the wedge-shaped slot 10, the locking block 310 is fixed by the clamping friction between the wedge-shaped slot 10 and the locking block 310, and the avoiding slot 305 and the vertical slot 304 can make the locking block 310 effectively inserted into the wedge-shaped slot 10, and the insertion depth of the wedge-shaped slot 10 can be deeper, so as to improve the clamping force of the wedge-shaped slot 10 on the locking block 310.

[0061] In an embodiment of the utility model, as shown in the figure, Figure 4 The clamping block 2 is provided with a V-shaped slot 21 on the side close to the syringe 100, that is, the contact area with the syringe 100 can be increased by arranging the V-shaped slot 21, so that the stability of the syringe 100 clamped by the clamping block 2 can be improved, and the V-shaped slot 21 can also play a role in limiting the syringe 100 in the longitudinal direction, so that the stability of the syringe 100 fixed can be further improved.

[0062] In an embodiment of the utility model, as shown in the figure, Figure 6 Further comprising a limiting block 6, the limiting block 6 is provided with a second U-shaped slot 60 penetrating through the limiting block 6 along the width direction of the limiting block 6, a plurality of clamping grooves 61 with different widths are arranged on the limiting block 6 and communicated with the second U-shaped slot 60, and the clamping grooves 61 are used for clamping the injection handle 1001 of the syringe 100.
