[0003] A test chamber is a chamber designed to simulate environmental conditions, such as temperature simulation chambers and humidity and heat simulation chambers. These chambers typically place the equipment and components to be tested inside and connect them to a test device or power supply outside the chamber via transmission lines. These transmission lines are connected to the outside of the chamber through the chamber's cable holes. During the chamber's manufacturing process, these holes are typically pre-cut in the chamber wall and fitted with cable bushings.

[0004] like Figure 1 As shown, the hole sleeve includes an inner hole sleeve 100 and an outer hole sleeve 200. The outer wall of the inner hole sleeve 100 is provided with a first flange 101 at one end and an external thread at the other end. The outer hole sleeve 200 is provided with a second flange 201 at one end and an internal thread at the other end. The inner hole sleeve 100 and the outer hole sleeve 200 are threadedly connected by the external and internal threads.

[0005] Usually, the box wall is composed of three parts: the outer box wall, the middle insulation cotton, and the inner box wall. The middle insulation cotton will support the outer box wall and the inner box wall to expand to both sides. In order to maintain the sealing of the threading hole, the size of the hole sleeve is designed as follows: after locking, the spacing between the two parallel first flanges and the second flange of the hole sleeve is consistent with the thickness of the box wall. However, due to the expansion of the insulation cotton, the current installation method of the hole sleeve is: when installing the test hole sleeve, two people are required to cooperate in the installation. One operator is responsible for pressing the inner hole sleeve in the box, and the other operator uses a jig to press the outer hole sleeve and rotate it to install. The current installation method requires two operators to cooperate with the operation, the operation efficiency is low, and the operation cost is high. Summary of the Invention

[0044] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0045] like Figure 1 As shown, the hole sleeve includes an inner hole sleeve 100 and an outer hole sleeve 200. The inner hole sleeve 100 has a first flange 101 on one end of its outer wall and an external thread on the other end. The outer hole sleeve 200 has a second flange 201 on one end of its outer wall and an internal thread on the other end. The inner hole sleeve 100 and the outer hole sleeve 200 are threadedly connected by external and internal threads. Both the inner hole sleeve 100 and the outer hole sleeve 200 have through holes. In this embodiment, the hole sleeve is installed in the threading hole of the test box wall as an example.

[0046] Specifically, the present invention provides a hole sleeve installation device, such as Figure 2-Figure 4As shown, the hole sleeve installation device includes a rotating mechanism 1 and a tensioning mechanism 2. The rotating mechanism 1 includes a cone 11 and a gripping member 12. The gripping member 12 is provided at the end of the cone 11 with a larger diameter. The gripping member 12 is provided to facilitate pressing and rotating the cone 11.

[0047] The tensioning mechanism 2 includes a pressing member 21 and a holding member 22. The holding member 22 slides through the cone 11. The middle portion of the pressing member 21 is rotatably connected to one end of the holding member 22 via a rotating shaft, and the pressing member 21 is opposite the end of the cone 11 with a smaller diameter. The pressing member 21 can rotate to a first position perpendicular to the central axis of the cone 11 or a second position at an angle less than 90 degrees to the central axis of the cone 11. When the pressing member 21 is in the first position, it can be pulled by the holding member 22 to press against the inner hole sleeve 100. When the pressing member 21 is in the second position, it can pass through the inner hole sleeve 100 and the outer hole sleeve 200.

[0048] When installing the hole sleeve, the operator can first install the inner hole sleeve 100 from inside the box into the wire threading hole, and fix the first flange 101 on the inner hole sleeve 100 to the inner box wall; then install the outer hole sleeve 200 from outside the box into the wire threading hole; rotate the tensioning piece, rotate the tensioning piece to the second position, and move the tensioning piece from outside the box through the outer hole sleeve 200 and the inner hole sleeve 100 to inside the box; then, rotate the tensioning piece to the first position, and insert the cone 11 into the through hole of the outer hole sleeve 200, and press the pressing piece 21 on the first flange 101 by pulling the holding piece 22. The first flange 101 applies pressure to the inner box wall, so that the inner box wall can be brought closer to the outer box wall through the first flange 101, avoiding the thermal insulation cotton from expanding the outer box wall and the inner box wall and affecting the connection between the inner sleeve hole and the outer sleeve hole. At the same time, the cone 11 is pressed tightly into the outer hole sleeve 200 through the holding piece 12, and the cone 11 is rotated. The friction between the cone 11 and the through hole of the outer hole sleeve 200 drives the outer hole sleeve 200 to rotate, and then the internal thread of the outer hole sleeve 200 and the external thread of the inner hole sleeve 100 are connected together. The whole process can be completed by a single person, thereby improving the installation efficiency of the hole sleeve and reducing labor costs.

[0049] To facilitate the securement of cone 11, a cone bottom cap 111 is provided at the larger diameter end of cone 11. The grip 12 is connected to cone bottom cap 111. A cone top cap 112 is provided at the smaller diameter end of cone 11. A first bolt (not shown) sequentially passes through cone bottom cap 111, cone 11, and cone top cap 112 to connect the three. If cone 11 wears, it can be replaced by removing the first bolt, making installation and removal easy.

[0050] Specifically, cone 11 is an elastomer that can transmit thrust and friction when squeezed. Preferably, cone 11 is made of PU. PU, also known as polyurethane (PU) elastomer, is a novel material intermediate between plastic and rubber, offering excellent strength and minimal compression deformation. PU combines the rigidity of plastic with the elasticity of rubber, resulting in excellent wear resistance, which helps extend the lifespan of cone 11.

[0051] In this embodiment, preferably, Figure 4 As shown, a receiving groove 221 is formed on one side of the holding member 22 along the central axis of the cone 11. The pressing member 21 is located at one end of the receiving groove 221 and is disposed between the two side walls of the receiving groove 221. One end of the pressing member 21 can be rotated into the receiving groove 221 so that the extending direction of the pressing member 21 is aligned with the central axis of the cone 11. In this way, when the pressing member 21 is in the second position, the overall structure of the holding member 22 and the pressing member 21 can be made more compact, making it easier to pass the pressing member 21 through the through holes of the outer hole sleeve 200 and the inner hole sleeve 100. In detail, in the direction of the holding member 22 toward the clamping member 21, the length of the bottom of the accommodating groove 221 is less than the length of the two side walls of the accommodating groove 221, and the clamping member 21 is located at a position where the two side walls of the accommodating groove 221 are longer than the bottom of the accommodating groove 221. When the clamping member 21 rotates to the second position, the bottom of the accommodating groove 221 can limit the clamping member, thereby preventing the clamping member 21 from continuing to rotate.

[0052] To facilitate rotation of the pressing member 21 to the first or second position, the weights at both ends of the pressing member 21 are different, with the rotation axis serving as the dividing line. Specifically, depending on the desired target position of the pressing member 21, the holding member 22 is rotated to position the pressing member 21 at the corresponding angle. Due to the different weights at both ends of the pressing member 21, the pressing member 21 can be rotated to the corresponding position.

[0053] In some optional embodiments, the lengths of the two ends of the pressing member 21 are different. It is understandable that due to the different lengths of the two ends of the pressing member 21, the weights of the two ends of the pressing member 21 are different.

[0054] In other embodiments, the materials of the two ends of the pressing member 21 are different. Specifically, the two ends of the pressing member 21 can be connected by welding. The two ends of the pressing member 21 have the same size and volume. Due to the different densities of the different materials, the weights of the two ends of the pressing member 21 are different.

[0055] Of course, the effect of different weights at both ends of the pressing member 21 can also be achieved by setting a counterweight at one end of the pressing member 21. Those skilled in the art can set it as needed, and it is not limited here.

[0056] In order to quickly rotate the pressing member 21 to the desired position, as shown in FIG. Figure 4As shown, the hole sleeve installation device in this embodiment also includes an identification portion 3, which is provided on the holding member 22 so as to rotate the pressing member 21 to the first position or the second position according to the identification portion 3. Alternatively, the identification portion 3 can be provided as a symbol drawn on the holding member 22, or by providing an identification part on the holding member 22 for differentiation, or by providing a circular hole in the holding member 22. Those skilled in the art can select the form of the identification portion 3 as needed, and this is not limited here.

[0057] like Figure 3 and Figure 4 As shown, the holding member 22 includes a first tensioning portion 222, a connecting member 223, and a second tensioning portion 224. The first tensioning portion 222 and the second tensioning portion 224 are connected by the connecting member 223, and the first tensioning portion 222 can rotate relative to the second tensioning portion 224. The pressing member 21 is connected to the second tensioning portion 224. It is understood that when the cone 11 is rotated by rotating the holding member 12, the first tensioning portion 222 can be rotated synchronously, so that the pressing member 21 presses the first flange 101, and the second tensioning portion 224 and the pressing member 21 do not need to rotate, thereby avoiding damage to the inner hole sleeve 100 due to the rotation of the pressing member 21. In some optional embodiments, the connecting member 223 is a tension bearing. The configuration of the tension bearing is conventional in the prior art and is not limited here. In other embodiments, the connecting member 223 includes a second bolt 2231 and a nut 2232, one end of the second bolt 2231 is fixed to the second tightening part 224 through the nut 2232, and the other end is rotatably connected to the first tightening part 222 and is limited to the first tightening part 222 by the head of the second bolt 2231.

[0058] like Figure 3 and Figure 4 As shown, the tensioning mechanism 2 further includes a tensioning handle 23, which is provided at one end of the holding member 22 away from the pressing member 21. The provision of the tensioning handle 23 makes it easier for the operator to pull the holding member 22.

[0059] In order to make the overall structure more compact and enable the operator to stably operate the tensioning mechanism 2 and the rotating mechanism 1, a slide groove 121 extending along the central axis of the cone 11 is provided on the gripping member 12, and the tensioning handle 23 is inserted into the slide groove 121.

[0060] Furthermore, the gripping member 12 includes a connecting portion 122 and a gripping rod 123. One end of the connecting portion 122 is connected to the cone 11, and the gripping rod 123 is provided at the end of the connecting portion 122 facing away from the cone 11. Specifically, the connecting portion 122 includes two parallel connecting rods spaced apart from each other. Both connecting rods are provided with a slide groove 121. The tightening handle 23 passes through the two slide grooves 121. The tightening handle 23 and the gripping rod 123 are parallel to each other, making it convenient for the operator to grasp the tightening handle 23 and the gripping rod 123 simultaneously.

[0061] This embodiment also provides a method for installing a hole sleeve, using the hole sleeve installation device described above, including the following steps:

[0062] S10, insert the inner hole sleeve 100 from the box into the threading hole, and fix the first flange 101 to the inner box wall.

[0063] In detail, the first flange 101 may be fixed to the inner box wall by screws.

[0064] S20, putting the outer hole sleeve 200 from outside the box into the threading hole.

[0065] S30, rotating the pressing member 21 to the second position, and moving the pressing member 21 from outside the box through the outer hole sleeve 200 and the inner hole sleeve 100 to inside the box.

[0066] The second position is preferably a position where the extension direction of the pressing member 21 is aligned with the central axis of the cone 11, so that the pressing member 21 can pass through the through holes of the outer hole sleeve 200 and the inner hole sleeve 100. During operation, the pressing member 21 can be accurately rotated to the second position by observing the marking portion 3 and rotating the holding member 22, thereby improving the efficiency of the operation.

[0067] S40 , rotating the pressing member 21 to the first position, and inserting the cone 11 into the outer hole sleeve 200 .

[0068] S50, tighten the holding member 22, push and rotate the holding member 12, and connect the outer hole sleeve 200 and the inner hole sleeve 100 together.

[0069] During operation, the tensioning handle 23 is pulled and the gripping rod 123 is pressed, and then the gripping rod 123 and the tensioning handle 23 are rotated at the same time, thereby achieving the compression of the compression member 21, the rotation of the cone 11 and the pressing of the cone 11 on the outer hole sleeve 200.

[0070] The pressing member 21 applies pressure to the inner box wall toward the outside of the box body to prevent the distance between the outer box wall and the inner box wall from increasing due to the expansion of the insulation cotton, thereby preventing the connection between the outer hole sleeve 200 and the inner hole sleeve 100 from being affected.

[0071] S60, release the holding member 22, use the holding member 22 to push the pressing member 21 into the box, rotate the pressing member 21 to the second position, and take the pressing member 21 out of the box through the inner hole sleeve 100 and the outer hole sleeve 200.

[0072] Specifically, by loosening the tightening handle 23 and pushing the tightening handle 23 , the pressing member 21 is pushed into the box.

[0073] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and are not to be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will readily conceive of other specific embodiments of the present invention without inventive effort, and such embodiments will fall within the scope of protection of the present invention.
