Description

Technical Field

[0001] The utility model belongs to the technical field of cold shrinkable tube testing, and more specifically, it particularly relates to a temperature testing device for cold shrinkable tubes. Background Art

[0002] A cold shrinkable tube is a rubber insulation sleeve basket pre-expanded on a drawable support tube, which forms a coating by using true radial pressure to play a role in waterproofing and moisture-proof sealing. It has excellent weather resistance and acid-base resistance, and is an ideal sealing product for communication cables, coaxial cables, and medium and low voltage power cables.

[0003] In the prior art, after retrieval, Chinese patent number CN202310354542.8 discloses a temperature testing device, including a testing box, a testing fixture, a moving mechanism, and a temperature control system. The testing box has a normal temperature chamber and a testing chamber that are isolated from each other. The testing fixture is used to accommodate the product to be tested, the moving mechanism is used to move the testing fixture between the normal temperature chamber and the testing chamber, and the temperature control system is used to keep the temperature of the testing chamber at the testing temperature.

[0004] The temperature resistance degree of the cold shrinkable tube is one of the important indicators determining its application range. After the cold shrinkable tube is produced, it is necessary to conduct a temperature resistance test on the cold shrinkable tube to ensure that the communication cold shrinkable tube can effectively protect the object to be sleeved for normal use. However, when the existing temperature testing device is in use, it is usually necessary to manually place the object to be tested into the testing device. Since the testing device is still in a high temperature or low temperature state after the test is completed, when batch testing of cold shrinkable tubes is required, manually taking and placing the test object by hand may lead to certain operation risks, and the material taking and placing operation process is relatively complicated, thus affecting the testing efficiency.

[0005] In response to the problems in the related art, no effective solution has been proposed yet. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0030] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc. indicating the orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the utility model.

[0031] Please refer to Figure 3 , 6 As shown in the figure, the present utility model is a temperature test device for cold shrinkable tubes, including a temperature test chamber 1. An isolation chamber 2 is fixedly installed on the outer surface of the temperature test chamber 1. A driving device 3 is arranged inside the isolation chamber 2. The output end of the driving device 3 is threadedly connected to a displacement device 4. The top of the displacement device 4 is rotatably installed with a support assembly 5. The top of the support assembly 5 is rotatably installed with a support sleeve 6. A tooth plate 7 is fixedly installed on the inner wall of the temperature test chamber 1. The tooth plates 7 are symmetrically arranged on both sides of the inner wall of the temperature test chamber 1. The bottom of the support assembly 5 is slidably connected to the inside of the temperature test chamber 1. A connecting rod 8 is fixedly installed on the outer surface of the support assembly 5. The bottom of the connecting rod 8 is fixedly installed with a second support assembly 9. A through groove 10 is opened on the inner wall of the temperature test chamber 1.

[0032] When it is necessary to perform a temperature test on the cold-shrinkable tube, it is sleeved outside the support sleeve 6, and the driving device 3 drives the displacement device 4 to drive the support assembly 5 at the top to displace, so that the support sleeve 6 and the cold-shrinkable tube are placed inside the temperature test chamber 1. After the temperature adjustment of the temperature test chamber 1 is completed, the driving device 3 is started to drive the displacement device 4 to displace along the inside of the temperature test chamber 1. At the same time, the support assembly 5 at its top is driven to displace, and the outer edge of the support assembly 5 meshes with the toothed plate 7. When the support assembly 5 gradually moves towards the outside of the temperature test chamber 1, it is driven by the toothed plate 7 to rotate. Until the support assembly 5 gradually displaces close to the outside of the temperature test chamber 1, the support assembly 5 continuously rotates to change the support positions of different support sleeves 6, and then the picking can be carried out.

[0033] In the present utility model, the bottom of the displacement device 4 is connected to the driving device 3. When it is necessary to pick and place the cold-shrinkable tube, the driving device 3 drives the displacement device 4 to displace inside the temperature test chamber 1, so as to provide a displacement driving force for the support assembly 5, enabling the support positions of the support assembly 5 and the support sleeve 6 to be arbitrarily changed inside the temperature test chamber 1. At the same time, a connecting rod 8 is provided to connect the displacement device 4 and the second support assembly 9, so that the second support assembly 9 can be driven to move together. And it cooperates with the toothed plate 7 to drive the support assembly 5 and the second support assembly 9 to rotate to change the position of the support sleeve 6, facilitating the operator to pick up the parts near the outside of the temperature test chamber 1 and reducing the adverse effects of high temperature or low temperature inside the temperature test chamber 1 on the operator.

[0034] In one embodiment, for the above-mentioned temperature test chamber 1, the temperature test chamber 1 includes a test box body 101, a heat preservation door 102 is hinged on the outer surface of the test box body 101, a horizontal platform 103 is fixedly installed inside the test box body 101, and a closed groove 104 is arranged on the top of the horizontal platform 103.

[0035] When it is necessary to perform a temperature test on the cold-shrinkable tube, the heat preservation door 102 can provide a closed heat preservation effect for the test box body 101, and the setting of the horizontal platform 103 can provide a bottom support effect for the displacement device 4 and the support assembly 5.

[0036] In one embodiment, for the above-mentioned driving device 3, the driving device 3 includes a driving motor 301, a driving screw 302 is arranged at the output end of the driving motor 301, the driving screw 302 extends into the closed groove 104, and a top groove is opened at the top of the closed groove 104.

[0037] By extending the driving screw 302 into the interior of the closed groove 104, the driving screw 302 is in a relatively enclosed space. When the driving motor 301 is started, the driving screw 302 rotates to drive the bottom of the displacement device 4 to displace along the gap of the top groove, thereby providing a displacement driving force for the displacement device 4 and driving it to move back and forth inside the test box 101.

[0038] In one embodiment, for the above-mentioned displacement device 4, the displacement device 4 includes a displacement socket 401, the displacement socket 401 is threadedly connected to the outside of the driving screw 302, a displacement top plate 402 is fixedly installed at the top of the displacement socket 401, and the support assembly 5 is rotatably installed at the top of the displacement top plate 402.

[0039] The displacement socket 401 is threadedly connected to the outer surface of the driving screw 302, and its top extends to the top of the top groove and is connected to the displacement top plate 402. Moreover, the displacement socket 401 is located inside the closed groove 104. When the driving screw 302 operates, it drives the displacement socket 401 to displace along the inside of the closed groove 104. At the same time, the bottom of the displacement top plate 402 slides on the top of the cross table 103 to limit its displacement path.

[0040] The closed groove 104 provides a semi-enclosed operating and moving space for the driving screw 302 and the displacement socket 401 on the top of the cross table 103. In this way, it can provide an effect of a closed and stable isolation space for the driving screw 302 inside the test box 101, enabling the displacement socket 401 to stably drive the top displacement top plate 402 to displace, and further providing a displacement driving force for the top support assembly 5 and the support sleeve 6, improving the convenience and efficiency of picking and placing parts.

[0041] In one embodiment, for the above-mentioned support assembly 5, the support assembly 5 includes a support disc 501, a support column 502 is fixedly installed at the top of the support disc 501, the support sleeve 6 is sleeved on the outside of the support column 502, and a disc tooth 503 is arranged on the outer surface of the support disc 501, and the disc tooth 503 meshes with the toothed plate 7.

[0042] The support disc 501 is rotatably connected to the top of the displacement top plate 402. When the displacement top plate 402 moves, it drives the support disc 501 to move together. At the same time, the outer edge of the support disc 501 meshes with the toothed plate 7 and is driven by the toothed plate 7 to rotate.

[0043] By arranging the disc tooth 503 on the outside of the support disc 501 and cooperating with the toothed plate 7, a self-rotation driving force can be provided for the support disc 501, so that the support sleeve 6 can rotate and change positions following the rotation of the support disc 501, facilitating the operator to pick up the cold shrinkage pipe fittings sleeved on the outside of the support sleeve 6 at different positions of the support column 502.

[0044] In one embodiment, for the above-mentioned second support assembly 9, the second support assembly 9 includes a second support plate 901, and a second support disk 902 is rotatably installed on the top of the second support plate 901. One end of the connecting rod 8 is fixedly connected to one side of the second support plate 901.

[0045] The inner part of the test box body 101 is divided into two groups of test cavities by the cross table 103. The second support plate 901 is connected to the displacement top plate 402 through the connecting rod 8. The second support disk 902 can provide more placement space for the cold shrinkable tube. Thus, when the displacement top plate 402 is driven to displace, the second support plate 901 can be driven by the connecting rod 8 to move together. The through groove 10 can provide an inner movement space for the connecting rod 8, thereby facilitating the picking of the cold shrinkable tubes on the two groups of support sleeves 6.

[0046] In one embodiment, for the above-mentioned test box body 101, a limiting block 11 is fixedly installed inside the test box body 101, and a bottom block 12 is fixedly installed at the bottom of the second support plate 901.

[0047] When the second support plate 901 displaces to be close to the outside of the test box body 101, when the bottom block 12 follows it to displace to the limiting block 11, it is blocked and restricted by the limiting block 11, so that the second support plate 901 stops displacing, playing a limiting role for it.

[0048] In one embodiment, for the above-mentioned test box body 101, a bottom sliding groove 13 is formed in the inner wall of the test box body 101, and the number of the bottom sliding grooves 13 is several groups.

[0049] The bottom sliding grooves 13 are respectively located at the bottoms of the displacement top plate 402 and the second support plate 901, facilitating providing sliding support and limiting effect for them, so that the displacement top plate 402 and the second support plate 901 always maintain the same displacement path.

[0050] Through the above technical solutions: 1. By connecting the bottom of the displacement device 4 to the driving device 3, when picking up and placing the cold shrinkable tube, the driving device 3 drives the displacement device 4 to move inside the temperature test chamber 1, thereby providing a displacement driving force for the support assembly 5, enabling the support position between the support assembly 5 and the support sleeve 6 to be arbitrarily changed inside the temperature test chamber 1. At the same time, a connecting rod 8 is provided to connect the displacement device 4 and the second support assembly 9, so that the second support assembly 9 can be driven to move together. In cooperation with the toothed plate 7, the support assembly 5 and the second support assembly 9 can be driven to rotate to change the position of the support sleeve 6, facilitating the operator to pick up the parts near the outside of the temperature test chamber 1 and reducing the adverse effects of high or low temperature inside the temperature test chamber 1 on the operator; 2. The closed groove 104 provides a semi-closed operation and movement space for the driving screw 302 and the displacement sleeve seat 401 on the top of the cross table 103, thereby achieving the effect of providing a closed and stable isolation space for the driving screw 302 inside the test box body 101, enabling the displacement sleeve seat 401 to stably drive the top displacement top plate 402 to move, and further providing a displacement force for the support assembly 5 and the support sleeve 6 at the top, improving the convenience and efficiency of picking up and placing the parts. By providing the disk teeth 503 on the outside of the support disk 501 and cooperating with the toothed plate 7, a self-rotation driving force can be provided for the support disk 501, enabling the support sleeve 6 to rotate and change its position following the rotation of the support disk 501, facilitating the operator to pick up the cold shrinkable pipe fittings sleeved on the outside of the support sleeve 6 at different positions of the support column 502.
