Description

Technical Field

[0001] This utility model relates to the field of temperature control switch testing technology, specifically a temperature control switch testing device. Background Technology

[0002] A temperature control switch is a series of automatic control elements that, based on changes in the ambient temperature, undergo internal physical deformation to produce specific effects, resulting in either switching on or off. It is also called a temperature protector or temperature controller, or simply a temperature controller. Alternatively, the temperature protector transmits the temperature data to the temperature controller, which then issues a switching command to control the equipment's operation to achieve the desired temperature and energy-saving effect.

[0003] After the temperature control switch is manufactured, it needs to undergo quality testing. Only those that pass the test can be put into the market. However, the current tests for temperature control switches are all for the circuit of the temperature control switch. The circuit and other components are installed inside the housing. Therefore, the housing also plays a crucial role in the entire temperature control switch and needs to be tested to detect the impact resistance of the temperature control switch housing.

[0023] 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.

[0024] Example

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in one embodiment of this utility model, a testing device for a temperature control switch includes a test bench 1, a mounting frame 2, an electric push rod 3, and a collision component 4. The collision component 4 is fixedly connected to the test bench 1 via the mounting frame 2, ensuring stable installation of the collision component 4. During use, it can effectively test the stable switch to be tested placed on the test bench 1. The pull rod 404 of the collision component 4 is slidably inserted into the first sliding sleeve 202. The upper end of the pull rod 404 is fixedly connected to the electric push rod 3 via a connecting rod, and the lower end is hooked to the upper end of the sliding rod 402 via a connecting fastener 403. The sliding rod 402 is slidably inserted into the second sliding sleeve 206, and the lower end of the sliding rod 402 is fixedly connected to the impact block 401. The adjusting nut 406 threaded on the sliding rod 402 abuts against the lower end of the support spring 405, and the upper end of the support spring 405 abuts against the stop rod 205 of the mounting frame 2, facilitating... During testing, the electric push rod 3 moves the pull rod 404. The pull rod 404 is connected to the slide rod 402 via the connecting fastener 403. As the pull rod 404 moves, it pulls the slide rod 402 and the lower impact block 401 together. During this process, the support spring 405 is compressed. As it moves upward, the contact plate 4034 of the connecting fastener 403 enters the unlocking sleeve 203. Under the action of the contact, the contact plate 4034 moves towards the pull rod 404. During the movement, the contact plate 4034 moves along with the lower buckle plate 4033 and separates from the protrusion 4021, releasing the pull rod 404 from pulling the slide rod 402. Then, under the action of the support spring 405, the slide rod 402 and the impact block 401 move downward quickly together, causing the impact block 401 to strike and collide with the housing of the temperature control switch to be tested, completing the test operation.

[0026] When it is necessary to adjust the impact force, the position of the adjusting nut 406 on the threaded section of the slide bar 402 can be adjusted according to actual needs to complete the adjustment of the pre-compression of the support spring 405, thereby completing the adjustment of the subsequent impact force.

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in some embodiments, the lower end of the slide rod 402 is fixedly inserted into the insertion seat provided on the upper part of the impact block 401, which facilitates a stable connection between the two. Thus, during the movement of the slide rod 402, the impact block 401 moves smoothly up and down. The slide rod 402 is provided with a threaded section on the rod body located below the stop rod 205, which is matched with the adjusting nut 406. The adjusting nut 406 is threadedly connected to the threaded section of the slide rod 402. The baffle integrally provided on the adjusting nut 406 abuts against the lower end of the support spring 405, which facilitates the smooth adjustment of the position of the adjusting nut 406 on the slide rod 402. Thus, the compression amount of the spring is preset, thereby determining the force of the impact block 401 impacting the temperature control switch to be tested, and smoothly completing the testing requirements of different needs.

[0028] The upper end of the slide rod 402 is fixedly connected to a protrusion 4021 that mates with the connecting fastener 403. The fastener plate 4033 of the connecting fastener 403 is hooked onto the protrusion 4021, which facilitates the stable connection of the upper end of the slide rod 402 to the connecting fastener 403, thus achieving a stable connection between the pull rod 404 and the slide rod 402. An abutment plate 4034 is integrally provided on the upper end of the fastener plate 4033. A connecting groove 4044 is provided at the transition between the abutment plate 4034 and the fastener plate 4033. Furthermore, the connecting sleeve 4032 is provided with… The ear plate 4031 is rotatably connected to the connecting groove 4044 via a pin, so that when the contact plate 4034 is subjected to external force, the buckle plate 4033 can rotate on the ear plate 4031, so that the buckle plate 4033 is separated from the protrusion 4021, the pull rod 404 pulls the slide rod 402, so that the slide rod 402 is separated from the pull rod 404, and the connecting sleeve 4032 is fixedly connected to the lower end of the pull rod 404, so that the connecting fastener 403 can be stably installed at the lower end of the pull rod 404, ensuring stable use;

[0029] The upper end of the pull rod 404 passes through the first sliding sleeve 202 and extends to the upper part of the top rod 201, and is fixedly connected to one end of the connecting rod. The other end of the connecting rod is fixedly connected to the telescopic end of the electric push rod 3, and the electric push rod 3 is fixedly connected to the top rod 201. This allows the electric push rod 3 to smoothly slide up and down on the top rod 201 of the mounting frame 2 through the connecting rod when it is running, thereby effectively driving the sliding rod 402 and the impact block 401.

[0030] like Figure 1 and Figure 2As shown, in some embodiments, the lower end of the mounting frame 2 is fixedly connected to the test bench 1, which facilitates the stable installation of the mounting frame 2 on the test bench 1, serving as a support frame for other components, so that the components can cooperate with each other for stable use and smoothly complete the test operation. The first sliding sleeve 202 is fixedly connected to the top rod 201, ensuring that the pull rod 404 can slide smoothly on the top rod 201, thereby effectively driving the sliding rod 402. The lower part of the first sliding sleeve 202 is integrally provided with an unlocking sleeve 203. The unlocking sleeve 203 has a frustum-shaped contact area inside that matches the upper contact plate 4034 of the buckle plate 4033, which facilitates the pull rod 404 to carry the sliding rod 402 through the connecting fastener 403. When the movement reaches the unlocking sleeve 203 position, the contact plate 4034 of the connecting fastener 403 first enters the frustum-shaped contact area of ​​the unlocking sleeve 203. As the connecting fastener 403 continues to move upward with the pull rod 404, the top of the contact plate 4034 moves towards the pull rod 404 under the action of the contact, so that the contact plate 4034 and the buckle plate 4033 separate from the protrusion 4021 at the upper end of the slide rod 402, and the pull on the slide rod 402 is released. Then, under the action of the support spring 405, it can quickly slide down, so that the impact block 401 at the lower end of the slide rod 402 can smoothly strike the temperature control switch to be tested, thereby effectively testing the housing of the temperature control switch.

[0031] The top rod 201 has a mounting hole 204 at the position corresponding to the electric push rod 3, which makes it easy to stably install the electric push rod 3 on the mounting frame 2, so that the electric push rod 3 can effectively drive the pull rod 404 and smoothly complete the test operation.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
