[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0035] See Figure 1-3 This embodiment provides a mechanical pressure transmission mechanism, including:

[0036] Mounting base 1;

[0037] Pressure measurement component 2 is used to obtain the pressure exerted on an object when it is pressed against it;

[0038] The drive assembly 3 is used to drive the pressure measuring assembly 2. The drive assembly 3 is fixed on the mounting base 1 and is driven to connect with the pressure measuring assembly 2.

[0039] In this embodiment, there are multiple pressure measuring components 2 and multiple driving components 3. Multiple driving components 3 are fixed to the mounting base 1, and each driving component 3 is connected to a multiple pressure measuring component 2. It can be seen that the arrangement of these multiple pressure measuring components 2 and multiple driving components 3 allows the mechanism to simultaneously test multiple test products, resulting in higher testing efficiency.

[0040] In this embodiment, the drive assembly 3 includes a drive member 31 and a movable member 32, which are drivenly connected. The movable member 32 is connected to the pressure measuring assembly 2, and the drive member 31 drives the pressure measuring assembly 2 through the movable member 32. Specifically, the drive member 31 can be a conventional cylinder to drive the movable member 32; the combination of the drive member 31 and the movable member 32 can also be a slider-type guide cylinder; in another implementation, the drive member 31 can also be a motor structure to drive the movable member 32 through a lead screw structure.

[0041] In this embodiment, the mechanism further includes a limiting component 4 for restricting the movement distance of the movable part 32. The pressure measuring component 2 is located on one side of the mounting base 1, and the limiting component 4 is fixedly connected to the movable part 32, with the limiting component 4 corresponding to the other side of the mounting base 1. By limiting the movement distance of the movable part 32 through the limiting component 4, the movement distance of the pressure measuring component 2 is limited when testing the test product.

[0042] In this embodiment, the limiting component 4 includes a limiting bracket 41 and a limiting adjusting member 42. The limiting bracket 41 is fixed to the movable member 32, and the limiting adjusting member 42 is movably disposed on the limiting bracket 41 to correspond to the other side of the mounting base 1. A limiting distance 43 is provided between the limiting adjusting member 42 and the other side of the mounting base 1, which can be adjusted by moving the limiting adjusting member 42. Specifically, the movable limiting member can be movably connected to the limiting bracket 41 by threads, and the limiting distance 43 between the limiting adjusting member 42 and the mounting base 1 can be adjusted by turning the movable limiting member.

The measuring head 23 is connected to, holds against, or corresponds in position to the pressure sensor 22. When the measuring head 23 holds and presses against the test product, under the action of the reaction force, the measuring head 23 presses against the pressure sensor 22, thereby obtaining the real-time pressure applied to the object through the pressure sensor 22. The movable measuring head 23 can indirectly achieve a universal pressure measurement function.

[0044] In this embodiment, the pressure measuring component 2 includes an elastic body 24, with its two ends connected to or abutting against a pressure sensor 22 and a measuring head 23, respectively. When the measuring head 23 abuts against and presses against the test product, under the action of the reaction force, the measuring head 23 compresses the elastic body 24, and through the elastic body 24, it compresses the pressure sensor 22, thereby obtaining the real-time pressure exerted on the object through the pressure sensor 22. The elastic body 24 is preferably a spring structure.

The two ends of the guide rod 26 are respectively provided in the first guide groove 251 and the second guide groove 231. An elastic body 24 is sleeved on the outside of the guide rod 26.

[0046] One end of the elastomer 24 is connected to or abuts against the second guide groove 231;

[0047] The other end of the elastic body 24 is disposed within the first guide groove 251; and the other end of the elastic body 24 is connected to or abuts against the guide block 25; or, the other end of the elastic body 24 is connected to or abuts against the end of the guide rod 26 located within the first guide groove 251. Specifically, the guide rod 26 is movably disposed within the second guide groove 231; the cooperation between the guide rod 26 and the first guide groove 251 and the second guide groove 231 serves as a guide when the measuring head 23 compresses the elastic body 24 to compress the pressure sensor 22.

[0048] In this embodiment, the end of the guide rod 26 located in the first guide groove 251 is fixed with a supporting part 261. The diameter of the supporting part 261 is larger than the diameter of the guide rod 26. The other end of the elastic body 24 is connected to or supports the supporting part 261.

[0049] In this embodiment, there are two or more measuring heads 23, all of which are movably connected to the measuring bracket 21, and all of which are connected to, abut against, or correspond in position to the pressure sensor 22. When testing the product, the multiple measuring heads 23 can distribute the pressure evenly.

[0050] In this embodiment, the measuring bracket 21 includes a connecting body 211, a first body 212, and a second body 213. The two ends of the connecting body 211 are fixed to the first body 212 and the second body 213 respectively. The pressure sensor 22 is disposed on the first body 212, and the measuring head 23 is movably disposed on the second body 213 to connect with, abut against, or correspond in position to the pressure sensor 22.

[0051] In this embodiment, the measuring head 23 includes a measuring end 232 and an anti-detachment end 233. The measuring end 232 and the anti-detachment end 233 are fixedly connected. The second body 213 is provided with an movable hole 2131 corresponding to the measuring end 232. The measuring end 232 is movably disposed in the movable hole 2131 and extends out of the second body 213 on the side away from the first body 212. The anti-detachment end 233 is disposed on the other side of the second body 213 close to the first body 212.

[0052] In this embodiment, a mounting groove 2132 is provided on the other side of the second main body 213, the movable hole 2131 is connected to the mounting groove 2132, and the anti-detachment end 233 is movably disposed in the mounting groove 2132.

[0053] In this embodiment, an installation guide groove 2133 that communicates with the installation groove 2132 is also provided on the other side of the second main body 213, and an anti-detachment guide part 2331 is fixedly provided on the anti-detachment end 233, and the anti-detachment guide part 2331 is movably disposed in the installation guide groove 2133.
