[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Please refer to Figures 1-8 The present invention provides a technical solution: a temperature control switch pressure test device, including a test platform 1, a protective cover 2 with an opening on one side is fixedly installed on the top of the test platform 1, a protective plate 3 is fixedly installed at the opening of the protective cover 2, a fixing component 5 for supporting and clamping the temperature control switch shell is provided above the test platform 1, an entry and exit mechanism 4 for pushing the fixing component 5 in and out of the protective cover 2 is provided on the top of the test platform 1, a pressing mechanism 6 for pressing down the temperature control switch shell located on the fixing component 5 is provided on the top inner wall of the protective cover 2, and the fixing component 5 includes four clamping plates 54 arranged in a rectangular shape. When the pressing mechanism 6 presses down the temperature control switch, the four clamping plates 54 will simultaneously approach and clamp the temperature control switch housing. When the pressing mechanism 6 moves upward and separates from the temperature control switch housing, the four clamping plates 54 will simultaneously move away and separate from the temperature control switch housing. The addition of the colorless transparent glass protective plate 3 makes it easier for workers to observe the deformation of the temperature control switch housing during the pressure test. It can also prevent the cracked temperature control switch housing from injuring the workers' eyes, thereby improving the safety of the testing process.

[0029] The pressing mechanism 6 includes a telescopic cylinder 61 fixedly mounted on the inner wall of the top of the protective cover 2 , and a pressing block 62 is fixedly mounted on the bottom end of the output rod of the telescopic cylinder 61 .

[0030] Furthermore, by controlling the extension of the telescopic cylinder 61 to push the pressing block 62 to press down the temperature control switch on the fixed component 5, the purpose of testing the shell strength of the temperature control switch is achieved, and by adjusting the downward force of the telescopic cylinder 61, different degrees of pressure resistance testing of the temperature control switch shell can be achieved.

[0031] The entry and exit mechanism 4 includes two guide rails 41 fixedly mounted on the top of the inspection platform 1, and the same slider 42 is slidably sleeved on the two guide rails 41. The fixing component 5 is installed on the top of the slider 42. A linear displacement module 43 is fixedly mounted on the top of the inspection platform 1. The slide on the linear displacement module 43 is fixedly connected to the bottom of the slider 42. A protective cover 44 covering one end of the linear displacement module 43 is fixedly mounted on the top of the inspection platform 1.

[0032] Furthermore, when performing a pressure resistance test on the housing of the temperature-controlled switch, the housing of the temperature-controlled switch is first placed on the fixed component 5 of the slider 42 outside the protective cover 2, and then the slider 42 is driven into the protective cover 2 by the linear displacement module 43, so that the housing of the temperature-controlled switch placed on the fixed component 5 is directly below the lower pressure block 62, and then the lower pressure block 62 can be driven by the telescopic cylinder 61 to press down the housing of the temperature-controlled switch. The protective cover 44 can cover the part of the linear displacement module 43 located outside the protective cover 2, which is not only more beautiful, but also can improve the safety of the linear displacement module 43 and avoid the linear displacement module 43 from being entangled with debris during operation.

[0033] The fixing assembly 5 includes a box body 51 fixedly mounted on the top of the slider 42. The top of the box body 51 is open. A top plate 52 is fixedly mounted at the top opening of the box body 51. Four moving mechanisms 53 that penetrate the top plate 52 and are slidably connected to the top plate 52 are provided on the top plate 52. Four splints 54 are fixedly connected to the corresponding moving mechanisms 53 respectively. A driving mechanism 55 that drives the four moving mechanisms 53 to move synchronously is rotatably mounted on the bottom of the top plate 52. A supporting mechanism 56 for supporting the temperature control switch is provided on the top plate 52. The supporting mechanism 56 penetrates the top plate 52 and is movably connected to the top plate 52, and will drive the driving mechanism 55 to rotate during the up and down movement of the supporting mechanism 56.

[0034] Four rectangular openings 521 are provided on the top plate 52, and a same horizontal bar 522 is fixedly installed between the inner walls on both sides of the opening 521. The moving mechanism 53 includes a second guide rail 531 fixedly installed on the top of the corresponding horizontal bar 522, and a second slider 532 is slidably sleeved on the second guide rail 531. The bottom of the splint 54 is fixedly connected to the second slider 532. The splint 54 also includes a frame 533 that passes through the opening 521 and is fixedly connected to both sides of the second slider 532.

[0035] Furthermore, by providing the second guide rail 531 , the movement of the second slider 532 with the clamping plate 54 can be made smoother.

[0036] The moving mechanism 53 also includes a lever 534 fixedly mounted on the bottom of the frame 533, and a bearing 535 is rotatably sleeved on the lever 534. The driving mechanism 55 includes a cylinder 551 that passes through the top plate 52 and is rotatably connected to the top plate 52. The bottom end of the cylinder 551 extends to the outside of the top plate 52 and is fixedly mounted with a disk 552. The disk 552 is provided with four rectangularly distributed arc holes 553. The four bearings 535 are respectively located in the corresponding arc holes 553 and are rollingly connected to the inner walls of the corresponding arc holes 553.

[0037] Furthermore, the rotation of the disc 552 can cause the four bearings 535 to roll in the corresponding arc-shaped holes 553. When the disc 552 rotates clockwise, the four bearings 535 will move toward the center of the circle at the same time. During this process, the four bearings 535 will carry the four frames 533 toward the center of the circle at the same time through the corresponding levers 534. The four frames 533 will carry the four clamps 54 to the center of the circle through the corresponding sliders 532 and clamp the temperature control switch housing placed on the supporting mechanism 56. When the disc 552 is reversed, the four moving mechanisms 53 will carry the four clamps 54 to move away from the center of the circle at the same time, thereby releasing the clamped temperature control switch housing.

[0038] A storage groove 523 is provided at the top center of the top plate 52, and a circular hole 524 is provided on the bottom inner wall of the storage groove 523. A cylinder 551 passes through the circular hole 524 and is rotatably connected to the inner wall of the circular hole 524. The supporting mechanism 56 includes a supporting plate 561 movably connected to the inner wall of the circular hole 524. A cylinder 562 is fixedly installed at the bottom of the supporting plate 561. The cylinder 562 passes through the cylinder 551 and is slidably connected to the inner wall of the cylinder 551.

[0039] Furthermore, when there is nothing on the top of the support plate 561, the support plate 561 is above the top plate 52. After the temperature control switch housing is placed on the support plate 561, as the lower pressing block 62 is pressed down, the support plate 561 will move down into the storage slot 523, and the top of the top plate 52 will be flush with the top of the support plate 561, so that the bottom of the temperature control switch housing can not only fall on the top of the support plate 561, but also fall on the top of the top plate 52, ensuring that the bottom of the temperature control switch housing can be fully supported.

[0040] A plurality of spiral guide ribs 554 distributed in a circular array are fixedly mounted on the inner wall of the cylinder 551 , and a spiral guide groove 566 adapted to the plurality of spiral guide ribs 554 is fixedly opened on the outer side of the cylinder 562 .

[0041] A spring 565 is fixedly installed in an embedded manner at the bottom end of the cylinder 562 , and a connecting plate 563 fixedly connected to the bottom inner wall of the box body 51 is fixedly installed at the bottom end of the spring 565 .

[0042] Furthermore, a circular groove for accommodating the spring 565 is provided at the bottom of the cylinder 562 , and the top end of the spring 565 is fixedly connected to the top inner wall of the circular groove.

[0043] Furthermore, when there is no external force on the top of the support plate 561, the bottom of the cylinder 562 remains flush with the bottom of the cylinder 551, and the top of the cylinder 562 is higher than the top of the cylinder 551. When the lower pressing block 62 presses down the temperature control switch housing placed on the top of the support plate 561 to move downward, when the support plate 561 pushes the cylinder 562 downward, the cylinder 551 will rotate clockwise and drive the disc 552 to rotate synchronously through the spiral guide groove 566 and the spiral guide rib 554. During this process, the bottom end of the cylinder 562 will contact the connecting disk 563, and the spring 565 will be completely retracted into the interior of the cylinder 562. When the lower pressing block 62 moves upward and separates from the temperature control switch, the compressed spring 565 will automatically reset and push the cylinder 562 to move upward. Guided by the spiral guide groove 566 and the spiral guide rib 554, the cylinder 551 will rotate counterclockwise with the disc 552.

[0044] Four limiting holes 525 distributed in a rectangular shape are provided on the bottom inner wall of the storage slot 523, and limiting rods 564 adapted to the four limiting holes 525 are fixedly installed on the bottom of the support plate 561. The bottom ends of the four limiting rods 564 extend into the corresponding limiting holes 525 and are slidably connected to the inner walls of the corresponding limiting holes 525.

[0045] Furthermore, the limiting guide of the four limiting rods 564 and the corresponding limiting holes 525 ensures that the supporting plate 561 can only move up and down with the cylinder 562.

[0046] In this embodiment: when in use, the rectangular temperature-controlled switch housing to be tested is placed on the supporting mechanism 56 located outside the protective cover 2, and then the entry and exit mechanism 4 moves the supporting mechanism 56 and the temperature-controlled switch housing to the inside of the protective cover 2, and makes the temperature-controlled switch housing be directly under the lower pressing block 62, and then the telescopic cylinder 61 drives the lower pressing block 62 to press down the temperature-controlled switch housing. In the process of the temperature-controlled switch housing moving down, the driving mechanism 55 is driven by the supporting mechanism 56 to rotate clockwise, and as the driving mechanism 55 rotates clockwise, the four moving mechanisms 53 will bring the four splints 54 to the center of the circle and press against the four sides of the temperature-controlled switch housing. As the four splints 54 continue to gather together, not only can the center of the temperature-controlled switch housing fall directly above the center of the supporting mechanism 56, but the four gathered splints 54 can also press tightly against the temperature-controlled switch housing. The four clamping plates 54 can simultaneously squeeze the four sides of the temperature control switch housing, so that the upper and lower parts and the front, back, left and right sides of the temperature control switch can all be tested for pressure resistance. After the test, the telescopic cylinder 61 moves up with the pressing block 62 and separates from the temperature control switch housing. Then, the supporting mechanism 56 automatically pushes up the temperature control switch housing. During the upward movement of the supporting mechanism 56, the driving mechanism 55 will rotate counterclockwise and move the four clamping plates 54 away from each other through the four moving mechanisms 53 and release the temperature control switch housing after the test. Then, the fixing assembly 5 and the temperature control switch housing can be sent out from the protective cover 2 through the in-and-out mechanism 4.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
