However, existing syringes placed on the support platform often lack a structure to firmly compress the syringe, making it prone to shifting or even falling during testing. This results in poor stability and hinders stable testing of the syringe, thus affecting the testing efficiency. Utility Model Content

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figures 1-4 As shown, a syringe strength testing device includes a base 1, on which a testing component and a clamping component are provided. The clamping component includes a first support platform 2 and a second support platform 3 that can move relative to each other. The base 1 is also provided with a control console for convenient operation of the testing device. The testing component includes a support plate 12 fixedly installed on the top of the base 1. A driving component 13 is fixedly installed on the top of the support plate 12, and the telescopic end of the driving component 13 is connected to a mounting plate 14. The driving component 13 can be one of a hydraulic cylinder, a pneumatic cylinder, and an electric telescopic rod. A pressure sensor 15 is installed at the bottom of the mounting plate 14, and a pressure head 16 is installed at the bottom of the pressure sensor 15. It also includes a clamping assembly, which comprises a first pressure plate 4 and a second pressure plate 5 that are adjustable in height, wherein: The first pressure plate 4 is located above the first support platform 2, and the first pressure plate 4 and the first support platform 2 are each provided with an end groove 19 corresponding to the conical end of the syringe barrel on the adjacent side. The second pressure plate 5 is located above the second support platform 3, and the second pressure plate 5 and the second support platform 3 are both provided with handle grooves 18 for limiting the syringe handle.

[0017] As described above, when testing the strength of the syringe, the first support platform 2 and the second support platform 3 can be moved and adjusted to increase the distance between them. Then, the handle of the syringe barrel is inserted into the handle groove 18 at the top of the second support platform 3. Subsequently, the first support platform 2 and the second support platform 3 are adjusted again to decrease the distance between them until the conical end of the syringe barrel is inserted into the end groove 19 at the top of the first support platform 2. This achieves the installation and fixation of the syringe barrel. Then, the driving component 13 drives the pressure head 16 to descend, causing the pressure head 16 to press down on the syringe barrel until it is deformed and damaged. During this process, the pressure sensor 15 monitors the pressure of the pressure head 16 on the syringe barrel in real time and displays it on the display screen on the control panel, thereby achieving the strength test of the syringe barrel for the production and use of the syringe. Furthermore, by utilizing the relative movable first support platform 2 and second support platform 3, as well as the adjustable first pressure plate 4 and second pressure plate 5, this utility model can clamp syringes of different specifications, thereby facilitating strength testing of syringes of different specifications, increasing the applicability of the testing device, improving the practicality of the testing device, and helping to achieve efficient testing of syringes of different specifications.

[0018] Furthermore, such as Figure 3 As shown, a positioning block is provided at the bottom of the first pressure plate 4, and a positioning hole that mates with the positioning block is provided at the top of the first support platform 2. When the first pressure plate 4 covers the top of the first support platform 2, the positioning block is inserted into the positioning hole to quickly position the first pressure plate 4 and the first support platform 2, thereby ensuring a stable fit between the first pressure plate 4 and the first support platform 2, which facilitates the stable clamping of the syringe syringe.

[0019] Furthermore, such as Figure 3 and Figure 4 As shown, a limit block is provided at the bottom of the second pressure plate 5, and a limit groove that cooperates with the limit block is provided at the top of the second support platform 3.

[0020] When the second pressure plate 5 covers the top of the second support platform 3, the limiting block is inserted into the limiting groove to quickly position the second pressure plate 5 and the second support platform 3, thereby ensuring a stable fit between the second pressure plate 5 and the second support platform 3, and further facilitating the stable clamping of the syringe.

[0021] Secondly, in this embodiment, regarding how the first pressure plate 4 and the second pressure plate 5 are adjusted in height, as follows: Figure 1 and Figure 3As shown, side plates 6 are fixed on the opposite sides of the first pressure plate 4 and the second pressure plate 5, and fixing plates 7 are installed on the opposite sides of the first support platform 2 and the second support platform 3. An adjusting screw 8 is provided on the fixing plate 7, and the top end of the adjusting screw 8 is rotatably connected to the bottom of the side plate 6.

[0022] When adjusting the first pressure plate 4 and the second pressure plate 5 to press the syringe barrel, the adjusting screw 8 can be rotated, causing the adjusting screw 8 to drive the first pressure plate 4 and the second pressure plate 5 to descend through the side plate 6 until the first pressure plate 4 covers the first support platform 2 and the second pressure plate 5 covers the second support platform 3, thereby pressing the syringe barrel. Conversely, when the syringe barrel needs to be removed after testing, the adjusting screw 8 can be rotated in the opposite direction, which will drive the first pressure plate 4 and the second pressure plate 5 to rise, so that the first pressure plate 4 separates from the first support platform 2 and the second pressure plate 5 separates from the second support platform 3, so that the syringe barrel can be removed.

[0023] Furthermore, such as Figure 1 and Figure 3 As shown, at least one limiting rod 11 is fixed to the bottom of the side plate 6, and the bottom end of the limiting rod 11 passes through the fixing plate 7 and extends to the bottom of the fixing plate 7. Specifically, in this embodiment, for ease of illustration, two limiting rods 11 are provided, and the two limiting rods 11 are symmetrically arranged on both sides of the adjusting screw 8. However, in practice, the design can be carried out according to the actual situation, and an appropriate number of limiting rods 11 can be selected. No limitation is made here.

[0024] When the adjusting screw 8 is rotated to adjust the height of the first pressure plate 4 and the second pressure plate 5, the limiting rod 11 moves along the fixed plate 7 to limit the distance between the side plate 6 and the fixed plate 7, thereby ensuring the stable lifting and lowering adjustment of the first pressure plate 4 and the second pressure plate 5.

[0025] Furthermore, in this embodiment, regarding how the first support platform 2 and the second support platform 3 move relative to each other, such as... Figure 1 and Figure 2 As shown, the base 1 has an internal shaft hole, and a bidirectional lead screw 10 is installed in the shaft hole. Two lead screw seats 17 are connected to the two opposite threaded sections of the bidirectional lead screw 10. The tops of the two lead screw seats 17 are respectively fixedly connected to the bottoms of the first support platform 2 and the second support platform 3. The base 1 also has a slot for the two lead screw seats 17 to move, and a motor 9 for driving the bidirectional lead screw 10 to rotate is installed on one side of the base 1. Specifically, the motor 9 can be a forward and reverse motor, and when the lead screw seats 17 move, the slot can limit the movement of the lead screw seats 17 to facilitate stable movement.

[0026] When clamping the syringe barrel, the bidirectional lead screw 10 can be driven to rotate by the motor 9. Then, the bidirectional lead screw 10 drives the first support platform 2 and the second support platform 3 to move in opposite directions through the lead screw seat 17, thereby increasing the distance between the first support platform 2 and the second support platform 3. Then, the handle of the syringe barrel is inserted into the handle groove 18 on the second support platform 3. Then, the bidirectional lead screw 10 is driven to rotate in the opposite direction by the motor 9, so that the first support platform 2 and the second support platform 3 can move towards each other through the lead screw seat 17, thereby decreasing the distance between the first support platform 2 and the second support platform 3, until the conical end of the syringe barrel is inserted into the end groove 19 on the first support platform 2, so as to realize the installation and fixation of the syringe barrel.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
