Description

Technical Field

[0001] The bristle testing device of the present application relates to the technical field, and in particular to a clamping structure of a bristle testing device. Background Art

[0002] As a daily oral cleaning tool for people, the comfort and cleanliness of the bristles of a toothbrush are important criteria for evaluating the quality of a toothbrush. Therefore, it is particularly important to test and evaluate various properties such as the softness, hardness and durability of the bristles of toothbrush products.

[0003] The clamping structure of the existing bristle testing devices on the market has a low degree of automation. When the clamping structure of the device clamps the head of a toothbrush, the position and clamping degree of the toothbrush head are usually adjusted by manually turning the tightening knob. The clamping structure has a low degree of automation, and the clamping stability of the bristles of the head is low during the test, and it is easy to shake. This not only makes it more laborious to use, but also has low work efficiency and is prone to errors. Summary of the Utility Model

[0004] The purpose of the present utility model is to solve the above technical problems, and provide a clamping structure of a bristle testing device. The testing device of the present application has a high degree of automation and is accurate and efficient.

[0005] In order to achieve the above purpose, the technical solution of the present utility model is as follows:

[0007] In this application, the first clamping block and the second clamping block are fixed to the clamping feet. Driven by the driving motor, the clamping distance formed between the first clamping block and the second clamping block can change with the expansion and contraction of the clamping feet. When the brush head is placed within the clamping distance, the driving motor drives the clamping feet to drive the first clamping block and the second clamping block to reduce the distance, thereby clamping the brush head tightly; with the support and limitation of the first support rib and the second support rib, the placement position of the brush head can be quickly determined during placement, facilitating operation; in addition, the limiting knob provided on the limiting portion formed by the extension of the first clamping block can further limit the brush head, increasing the clamping stability; through the cooperation of the first clamping block and the second clamping block, the brush head is clamped and released under the drive of the clamping feet, and when testing the performance of the bristles, the overall automation degree is high and the work efficiency is high.

[0008] In one embodiment, the side of the second clamping block that cooperates with the limiting portion is a stepped surface, and there is a gap between the stepped surface and the bottom of the limiting portion.

[0009] In one embodiment, the side walls of the first clamping block and the second clamping block near the bottom are both provided with arc-shaped grooves.

[0018] The embodiment of the present application provides a clamping structure for a bristle testing device, which is used to solve the technical problems that the clamping structure of the existing bristle testing device has low automation, and the clamping stability of the brush head bristles during the test is relatively low, easy to shake, not only laborious to use, but also low in work efficiency and easy to generate errors.

[0019] In order to make the invention purpose, features and advantages of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the embodiments described below are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0020] Please refer to Figures 1 to 3 The embodiment of the present application provides a clamping structure for a bristle testing device. The clamping structure is installed on a base 100 and includes a fixture 200, a first clamping block 300 and a second clamping block 400. The fixture 200 is connected with a driving motor 210 and installed on the base 100. The fixture 200 is provided with a retractable clamping foot 220. The first clamping block 300 and the second clamping block 400 are respectively fixed on the clamping feet 220 on both sides. A clamping distance is formed between the first clamping block 300 and the second clamping block 400. The first clamping block 300 and the second clamping block 400 are respectively horizontally extended with a first support rib 310 and a second support rib 410 within the clamping distance to limit the brush head. When the clamping foot 220 retracts and extends, it drives the first clamping block 300 and the second clamping block 400 to move apart accordingly. The first clamping block 300 extends to the other side with a limiting portion 320. The limiting portion 320 is located above the second clamping block 400 and has a matching shape. A limiting knob 321 for abutting against the brush head is installed on the limiting portion 320.

[0021] Specifically, the driving motor 210 is fixed on the fixing bracket of the base 100. A clamp 200 is connected to the lower side of the driving motor 210. The clamp 200 is provided with a chute for the clamping feet 220 to slide. The clamping feet 220 are symmetrically distributed in the chute. When the driving motor 210 works, the clamping feet 220 move in the chute. The first clamping block 300 and the second clamping block 400 are respectively fixed on the clamping feet 220 on both sides and move along with the movement of the clamping feet 220. A clamping distance with a telescopic space is formed between the first clamping block 300 and the second clamping block 400 under the drive of the clamping feet 220 to fixedly clamp the brush head. When the clamping feet 220 expand, the clamping distance increases, and at this time, the brush head can be taken out or placed. When the clamping feet 220 contract towards the middle, the clamping distance decreases, so that the brush head placed between the first clamping block 300 and the second clamping block 400 can be clamped and fixed for testing; first support ribs 310 and second support ribs 410 respectively horizontally extend from the bottom of the opposite side walls of the first clamping block 300 and the second clamping block 400 to form a platform for supporting the brush head. Both sides of the brush head can be hung on the first support ribs 310 and the second support ribs 410, and quick positioning can be achieved during placement; one side of the first clamping block 300 extends towards the second clamping block 400 to form a limiting part 320, and extends to the upper side of the second clamping block 400. The shape of the second clamping block 400 matches that of the limiting part 320. By setting a limiting knob 321 in the limiting part 320 to abut against the upper end surface of the brush head, the movement of the brush head in the vertical direction can be further limited, and then the brush head can be clamped and limited in multiple directions for the test of the bristles. Not only is the overall automation degree high, but also the operation is convenient and the clamping stability is high.

[0022] Further, the side of the second clamping block 400 that cooperates with the limiting part 320 is a stepped surface 420, and there is a gap between the stepped surface 420 and the bottom of the limiting part 320. A stepped surface 420 is formed at the position corresponding to the limiting part 320 of the second clamping block 400. The shape of the stepped surface 420 matches that of the limiting part 320. When the first clamping block 300 and the second clamping block 400 clamp the brush head, the limiting part 320 is located above the stepped surface 420, and there is a gap between the bottom of the limiting part 320 and the stepped surface 420, so as to ensure that no interference will occur during clamping. The setting of the limiting part 320 enables the first clamping block 300 to install the limiting knob 321 while clamping the brush head with the second clamping block 400, and the structure is simple.

[0023] Furthermore, arc-shaped grooves 340 are provided on the side walls near the bottom of the first clamping block 300 and the second clamping block 400. Arc-shaped grooves 340 are provided on the opposite side walls of the first clamping block 300 and the second clamping block 400. The arc-shaped grooves 340 are adapted to the shape of the brush head. And arc-shaped grooves adapted to the shape of the brush head are correspondingly formed at the positions of the first support rib 310 and the second support rib 410 corresponding to the arc-shaped grooves 340. Thus, when the brush head is placed, it can be quickly positioned, the clamping is more suitable, the two sides of the brush head are not easily damaged, and it is convenient for the user to use. Among them, the position of the arc-shaped groove 340 corresponds to the position of the limit knob 321. The limit knob 321 is located at the center of the arc-shaped groove 340, and thus can abut against the middle part of the brush head to improve the stability of clamping.

[0024] Furthermore, the clamping feet 220 are symmetrically distributed. A first installation groove 350 is provided on the outer wall of the first clamping block 300, and a second installation groove 430 is provided on the outer wall of the second clamping block 400. The first clamping block 300 is sleeved on one of the clamping feet 220 through the first installation groove 350, and the second clamping block 400 is sleeved on the other clamping foot 220 through the second installation groove 430. The first clamping block 300 and the second clamping block 400 are both fixed to the clamping feet 220 by threaded connection. The first installation groove 350 and the second installation groove 430 adapted to the clamping feet 220 are respectively formed on the outer side walls of the first clamping block 300 and the second clamping block 400. During installation, they are fixedly connected to the clamping feet 220 through threaded connection with the installation grooves. Thus, when they can be quickly fixed to the clamping feet 220, the installation is simple. And because the shapes of the first installation groove 350 and the second installation groove 430 are adapted to the clamping feet 220, when the clamping feet 220 move, the first clamping block 300 and the second clamping block 400 have high stability and are not easily shaken, ensuring that the test results are relatively accurate.

[0025] Furthermore, a limit groove 322 is provided on the lower side of the limiting part 320. A limit rib extends from the bottom of the limit groove 322, and the limit rib is parallel to the first support rib 310. The limit knob 321 includes a limit post 3211. The limit post 3211 passes through the limit groove 322, and the limit knob 321 is adjusted so that the limit post 3211 abuts against the upper end face of the brush head. The limit groove 322 has the same width as the minimum clamping distance when clamping the brush head and is located on the upper side of the clamping distance. Limit ribs 323 parallel to the first support rib 310 and the second support rib 410 extend from the bottom of the inner walls on both sides of the limit groove 322, forming a space for placing the brush head with the first support rib 310 to limit the vertical movement of the brush head. The limit post 3211 of the limit knob 321 passes through the limit groove 322, and the limit knob 321 is adjusted to adjust the position of the limit post 3211 until it abuts against the brush head, further enhancing the clamping stability of the brush head and ensuring that the test results are more accurate.
