Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a stainless steel online pipe network sleeve traction assembly fixture. Background Technology

[0002] Stainless steel connecting pipes are commonly used to connect the outdoor and indoor units of portable air conditioners. Internally, stainless steel corrugated pipes are typically used to transfer refrigerant, while externally, a welded wire mesh sleeve protects the corrugated pipe and prevents refrigerant leakage due to external damage during transportation, installation, or use. However, existing stainless steel connecting pipes and their mesh sleeves are prone to gaps between the wire mesh sleeve and the stainless steel connecting pipe body due to its own expansion properties. This results in a failure to achieve a tight fit with the corrugated pipe body after welding, affecting the protective effect and failing to achieve the expected protective function.

[0003] Therefore, this application provides a stainless steel online pipeline sleeve traction assembly fixture to meet the requirements. Utility Model Content

[0004] The purpose of this application is to provide a stainless steel connecting pipe mesh sleeve traction assembly fixture, which aims to solve the problem that in existing stainless steel connecting pipes and their mesh sleeves, the steel wire mesh sleeve of the connecting pipe is prone to gaps between itself and the stainless steel connecting pipe body due to its own expansion, which leads to the inability to tightly fit the corrugated pipe body after welding, affecting the protection effect and failing to achieve the expected protection function.

[0005] To achieve the above objectives, this application provides the following technical solution: a stainless steel online pipeline sleeve traction assembly fixture, comprising a bracket, an upper traction rubber wheel, a lower traction rubber wheel, and a pre-tightening mechanism;

[0006] The bracket includes two opposing side plates;

[0007] The lower traction rubber wheel is rotatably connected between the two side plates of the bracket via the first rotating shaft;

[0008] The upper traction roller is rotatably connected between the two side plates of the bracket via the second rotating shaft, and the upper traction roller is positioned above the lower traction roller. The position of the upper traction roller on the bracket can be adjusted radially.

[0009] The pre-tightening mechanism is mounted on the bracket and is used to apply an adjustable radial clamping force to the upper traction roller so that a pressure is formed between the upper and lower traction rollers to tighten the braided sleeve of the stainless steel connecting pipe.

[0010] The outer circumferential surfaces of both the upper and lower traction rollers are provided with grooves that match the shape of the stainless steel connecting pipe. Through the cooperation between the above components, the clamp can effectively tighten the mesh sleeve, ensuring that it fits tightly against the pipe body, avoiding gaps after welding, and improving the protective effect of the mesh sleeve.

[0011] Preferably, the pre-tightening mechanism includes a locking screw, a compression spring, and a limiting block. There are two sets of limiting blocks. The limiting blocks are installed on the side plate of the bracket by the locking screw and are located above the upper traction rubber wheel. The compression spring is arranged between the limiting block and the second rotating shaft, so that the upper traction rubber wheel receives radial clamping force.

[0012] Preferably, a guide post is connected to the limiting block, and a pre-set groove adapted to the compression spring is opened on the lower end face of the guide post; the compression spring is installed in the pre-set groove of the guide post; the second rotating shaft of the upper traction rubber wheel is opened with an installation groove adapted to the compression spring, so as to improve the stability and accuracy of the compression spring's force application.

[0013] Preferably, the side plate of the bracket is provided with a guide groove for guiding the second shaft of the upper traction rubber wheel to move radially. The design of the guide groove is conducive to the smooth movement of the upper traction rubber wheel.

[0014] Preferably, both the upper and lower traction rollers are made of silicone or a material with similar elastic properties to silicone. The use of elastic materials improves the adaptability of clamping and the protection of the tube.

[0015] In summary, the technical effects and advantages of this utility model are as follows:

[0016] In this invention, by setting an upper traction roller and a lower traction roller, with the upper traction roller having a preload provided by a compression spring and working together with the lower traction roller to clamp the wire mesh sleeve of the inner stainless steel connecting pipe, and utilizing the space where the groove of the traction roller completely fits the wire mesh sleeve and the stainless steel connecting pipe, the wire mesh sleeve of the stainless steel connecting pipe is effectively tightened and tightly adhered to the stainless steel connecting pipe body before welding. This solves the problem of the wire mesh sleeve not fitting properly after welding due to its expansion. Through the above clamping and traction process, this fixture ensures that there are no gaps between the wire mesh sleeve and the stainless steel connecting pipe before the wire mesh sleeve is locked by the fixing clamp and welding is performed. This ensures that the wire mesh sleeve remains tightly fitted after welding, without gaps, effectively improving the protection of the stainless steel connecting pipe.

[0017] A clamp is provided that can effectively and adjustably tighten the external wire mesh sleeve of stainless steel connecting pipes. It has a relatively simple structure, is easy to operate, and helps to improve product quality and production efficiency. Attached Figure Description

[0025] 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. Example

[0026] refer to Figure 1-5 The stainless steel connecting pipe mesh sleeve traction assembly fixture shown includes a bracket 1, an upper traction rubber wheel 9, a lower traction rubber wheel 10, and a locking mechanism. The bracket 1 consists of two parallel side plates. To prevent the steel wire mesh sleeve of the stainless steel connecting pipe 8 from not fitting the corrugated pipe after welding due to expansion, thus failing to provide protection, the upper traction rubber wheel 9 and the lower traction rubber wheel 10 are installed between the two sets of side plates. The lower traction rubber wheel 10 is installed on the lower part of the side plate via a first rotating shaft 2, while the upper traction rubber wheel 9 is installed on the upper part of the side plate via a second rotating shaft 3. The upper traction rubber wheel 9 is positioned above the lower traction rubber wheel 10, and its position on the side plate can be adjusted radially. The locking mechanism is installed on the side plate and is located above the upper traction rubber wheel 9.

[0027] As one embodiment of this invention, in order to give the upper traction roller 9 a downward preload, the locking mechanism also includes a limiting block 7 and a compression spring 5. The compression spring 5 is located between the second rotating shaft 3 and the limiting block 7. The limiting block 7 is mounted on the side plate of the bracket 1 by a locking screw 4, and the side plate of the bracket 1 is provided with a guide groove for the radial movement of the second rotating shaft 3. In order to make the radial movement of the compression spring 5 and the upper traction roller 9 more stable, the limiting block 7 is also connected to a guide post 6. The lower end face of the guide post 6 is provided with a pre-set groove for installing the compression spring 5, and the second rotating shaft 3 is also provided with an installation groove that matches the compression spring 5. The two ends of the compression spring 5 are located in the pre-set groove and the installation groove, respectively. Under the action of the compression spring 5, the upper traction roller 9 and the second rotating shaft 3 have a radial preload. When the stainless steel connecting pipe 8 with the wire mesh sleeve passes through the upper traction roller 9, the upper traction roller 9 rotates around the second rotating shaft 3 as the axis, while the second rotating shaft 3 does not rotate.

[0028] As one embodiment of this invention, in order to make the upper traction roller 9 and the lower traction roller 10 fit more closely to the stainless steel connecting pipe 8, the upper traction roller 9 and the lower traction roller 10 are provided with grooves that are adapted to the shape of the stainless steel connecting pipe 8, and the upper traction roller 9 and the lower traction roller 10 are both made of silicone or a material with elastic characteristics similar to silicone.

[0029] The working principle of this utility model is as follows: In use, the operator first installs the lower traction roller 10 between the two sets of side plates of the bracket 1 via the first rotating shaft 2. Then, the upper traction roller 9 is installed into the guide groove on the side plate of the bracket 1 via the second rotating shaft 3. Next, one end of the compression spring 5 is placed in the mounting groove on the second rotating shaft 3. Then, the limiting block 7 is installed onto the side plate of the bracket 1 via the locking screw 4, while the other end of the compression spring 5 is placed in the pre-set groove of the guide post 6. Afterward, the wire mesh sleeve of the stainless steel connecting pipe 8 can be tightened. The operator first passes the stainless steel connecting pipe 8 through the wire mesh sleeve, then inserts the inner wire mesh sleeve of the stainless steel connecting pipe 8 into the groove between the upper traction roller 9 and the lower traction roller 10. The exposed end is secured using a fixing clip. Tighten, then pull out the stainless steel connecting tube 8 with the wire mesh sleeve through the rotation direction of the upper traction rubber wheel 9 and the lower traction rubber wheel 10. Use the pressure of the compression spring 5 on the top of the upper traction rubber wheel 9 to close the upper traction rubber wheel 9 and the lower traction rubber wheel 10. Since the upper traction rubber wheel 9 and the lower traction rubber wheel 10 are both made of relatively soft silicone, the groove travel of the outer surface of the upper traction rubber wheel 9 and the lower traction rubber wheel 10 is completely fitted with the stainless steel connecting tube 8 with the wire mesh sleeve. After the stainless steel connecting tube 8 with the wire mesh sleeve has passed through the entire device, lock it at the end simultaneously with the fixing clamp before welding. This ensures that the wire mesh sleeve will not expand and will not create a gap between it and the stainless steel connecting tube 8.
