Description

Technical Field

[0001] The invention relates to the technical field of air-conditioning liquid collecting pipes, and in particular to an air-conditioning condenser liquid collecting pipe correction device. Background Art

[0002] The condenser, one of the four major components of an air conditioner, is a heat exchanger used to cool and liquefy the high-temperature, high-pressure steam compressed by the refrigeration compressor. This gas must be throttled and depressurized through capillary tubes in the piping system to liquefy it. Metals like copper have high heat conduction efficiency and are commonly used to transport refrigerant in air conditioner production.

[0003] During the production of manifolds, long straight pipes are cut uniformly and then processed. This long straight pipe can bend during storage, requiring correction and adjustment after the cut manifolds are cut. Correction and adjustment involve applying pressure to the manifolds, which can easily cause deformation or unevenness. Filling with a support material can reduce damage to the manifold during correction. Furthermore, manifold correction is a process of deformation, and conventional fillings can easily lose their support during the process, making removal difficult. Summary of the Invention

[0004] In response to the deficiencies in the prior art, the present invention provides an air-conditioning condenser collecting pipe correction device and discloses a filler. The filler has bendable toughness and the ability to expand outward. After passing through the collecting pipe, the filler expands by pulling to fully support the inner wall of the collecting pipe and has a tendency to straighten. It can adapt to changes in the deformation state of the collecting pipe and is easy to remove.

[0005] In order to solve the above technical problems, the present invention solves them through the following technical solutions. In addition, the correction of the collecting tube is a process of deformation. Ordinary fillings are prone to lose their supporting force in the process of adapting to the deformation, and there is also the problem of difficulty in removal.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] An air conditioner condenser liquid collecting pipe correction device, comprising a filler, the filler being used to pass through the interior of the liquid collecting pipe and support the inner wall thereof;

[0008] The invention also includes a fixing seat and a tractor, wherein the fixing seat is connected and fixed to one end of the filler to control it to pass through the liquid collecting pipe, the filler is in clearance with the inner wall of the liquid collecting pipe, and the tractor is connected to one end of the filler to tension it so that the filler is in contact with the inner wall of the liquid collecting pipe and provides support;

[0009] The filler is composed of a plurality of expansion mechanisms connected in series, and two connected expansion mechanisms are movably connected.

[0010] Preferably, the expansion mechanism includes an expansion member, a pulling member, and a rope. The expansion member is installed on the pulling member. The rope passes through the pulling member to pass into another pulling member. The tractor is connected to the rope at the end to control the expansion of the expansion member by pulling the rope.

[0011] Preferably, the expansion piece includes a base, a support plate, and a pulling rod;

[0012] The base is evenly distributed with first sliding grooves on the circumference, the support plate is slidably arranged on the base, a support frame passing through the first sliding groove is vertically fixed on the support plate, one end of the pulling rod is movably connected to the support frame, and the other end is movably connected to the pulling member.

[0013] Preferably, the pulling member comprises a tube body with a second sliding groove formed in the circumference thereof, the tube body being fixed to the middle portion of the base, and the second sliding groove connecting the inner cavity of the tube body with the outside;

[0014] A spherical plug and a spherical groove are fixed at both ends of the tube body respectively, and the two ends of the tube body are communicated with the outside through the spherical plug and the spherical groove.

[0015] Preferably, a slider is provided inside the tube body for sliding, and a spring in contact with the slider is installed inside the tube body. The spring squeezes the slider to be located at one end of the tube body, and one end of the rope is fixed on the slider and the other end passes through the spherical groove.

[0016] Preferably, a support seat connected to the pulling rod is installed inside the second sliding groove, and the support seat is fixed to the sliding block after passing through the interior of the tube body.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The present invention provides an air-conditioning condenser collecting pipe correction device, which discloses a filler. The filler has bendable toughness and the ability to expand outward. After passing through the collecting pipe, it expands by pulling to fully support the inner wall of the collecting pipe and has a tendency to straighten. It can adapt to the deformation state of the collecting pipe and is easy to remove.

[0023] In the filler provided by the present invention, the traction device achieves displacement of the traction member and allows the expansion member to unfold by pulling the rope. After the pulling force of the traction device is removed, the spring can cause the filler to reset for easy removal. In addition, the ball plug and the ball groove are movably connected, allowing the filler to bend to adapt to the deformation of the liquid collection tube.

[0024] The present invention arranges ropes in sections and connects adjacent ropes through sliders.

Moreover, when the ropes move, the distance between adjacent expansion mechanisms remains unchanged, thereby maintaining the support surface.

[0025] In addition, the protruding ball plug and ball groove of the present invention account for a relatively small proportion of the overall length of the expansion mechanism, which can increase the supporting area for the liquid collecting pipe.

[0026] The ball plug and the ball groove as well as the rope and the slider in the present invention can be disassembled, so that the expansion mechanism with cracks and damage can be easily replaced. BRIEF DESCRIPTION OF THE DRAWINGS

The preferred embodiments described below are for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0037] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "left", "right", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate directions or positions are based on the directions or positional relationships shown in the accompanying drawings, which are merely simplified descriptions for the convenience of describing the present invention, and do not indicate or imply that the device or component referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, the above terms should not be understood as limiting the present invention.

[0038] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity. Example

[0039] See also Figure 1-6 The present invention provides an air-conditioning condenser collecting pipe correction device, including a filler 1, a fixing seat 2 and a traction device 3. The filler 1 is used to pass through the inside of the collecting pipe and support its inner wall. The fixing seat 2 is connected and fixed to one end of the filler 1 to control it to pass through the collecting pipe. The filler 1 and the inner wall of the collecting pipe are clearance-matched. The traction device 3 is connected to one end of the filler 1 to tension it so that the filler 1 fits into the inner wall of the collecting pipe and supports it. The filler 1 is composed of multiple expansion mechanisms connected in series, and the two connected expansion mechanisms are movably connected.

[0040] The filler 1 provided in this application is used for correction of the liquid collecting pipe. Since the liquid collecting pipe is made by evenly cutting a long straight pipe, the long straight pipe is bent during storage, which causes the cut liquid collecting pipe to need correction and adjustment. Correction and adjustment is a process of applying pressure to the liquid collecting pipe, which can easily cause the liquid collecting pipe to deform or become concave and convex. The filler 1 is composed of multiple expansion mechanisms in series and has sufficient flexibility for passing through the liquid collecting pipe. Before use, the diameter of the filler 1 is smaller than the inner diameter of the liquid collecting pipe. By applying force to the filler 1, it can be expanded and adhered to the inner wall of the liquid collecting pipe for support, which can avoid damage to the liquid collecting pipe during the correction process. In particular, the use effect of thin-walled liquid collecting pipes is more prominent.

[0041] In an embodiment of the present application, the filler 1 is installed on a fixed seat 2. After the fixed seat 2 approaches the liquid collecting pipe, the filler 1 passes through the liquid collecting pipe. After passing through the liquid collecting pipe, the filler 1 is caught by the tractor 3, and the tractor 3 applies a pulling force backward to expand the filler 1.

[0042] In an embodiment of the present application, the expansion mechanism is composed of an expansion member 4, a pulling member 5, a rope 6, etc. The expansion member 4 is installed on the pulling member 5, and the rope 6 passes through the pulling member 5 for passing into another pulling member 5. The traction device 3 is connected to the rope 6 at the end to control the expansion of the expansion member 4 by pulling the rope 6.

[0043] It should be noted that the expansion part 4 includes a base 41, a support plate 42, a pulling rod 43, etc.; the first sliding grooves 44 are evenly distributed circumferentially on the base 41, the support plate 42 is arranged on the base 41, and a support frame 45 passing through the first sliding groove 44 is vertically fixed on the support plate 42, and one end of the pulling rod 43 is movably connected to the support frame 45, and the other end is movably connected to the pulling part 5.

[0044] Two support plates 42 are connected to the support frame 45. These plates 42 are located at the upper and lower ends of the base 41 and slide along the first slide groove 44 with the support frame 45. Two sets of pull rods 43 are arranged in parallel at the upper and lower sides of the base 41 to distribute the supporting force between the two support plates 42. Initially, the pull rods 43 are tilted. After the pull member 5 changes, the pull rods 43 become horizontal and push the support plates 42 and support frame 45 outward to support the inner wall of the liquid collecting pipe.

[0045] It should be noted that the pulling member 5 includes a tube body 51 with a second slide groove 52 opened circumferentially. The tube body 51 is fixed in the middle of the base 41, and the second slide groove 52 connects the inner cavity of the tube body 51 with the outside; a ball plug 53 and a ball groove 54 are respectively fixed at both ends of the tube body 51, and the two ends of the tube body 51 are connected to the outside through the ball plug 53 and the ball groove 54.

[0046] When two expansion mechanisms are connected, the ball plug 53 of one expansion mechanism is inserted into the ball groove 54 of the other expansion mechanism for clamping and can realize universal rotation. The clamping can be separated by applying external force.

[0047] A slider 55 is slidably mounted within the tube body 51, and a support seat 57 is slidably mounted within the second slide groove 52. One end of the support seat 57 is connected to the pull rod 43, and the other end is fixed to the slider 55. The two sets of pull rods 43 are respectively mounted at both ends of the slider 55. Furthermore, a spring 56 is mounted within the tube body 51, in contact with the slider 55, and presses the slider 55 toward the end closest to the ball plug 53.

[0048] It should be noted that one end of the rope 6 is fixed to the slider 55 and the other end passes through the spherical groove 54. A clamping piece 61 is fixed to the end of the rope 6, and protrusions 62 are evenly distributed in multiple layers in the circumferential direction on the clamping piece 61.

[0049] In addition, a locking groove 58 is formed at one end of the slider 55 facing the ball plug 53 , and the ball plug 53 is rotatably connected to the tube body 51 . The thickness of the locking member 61 is greater than the depth of the locking groove 58 .

[0050] When the two expansion mechanisms are spliced, the clamping member 61 passes through the ball plug 53 and enters the slot 58, and the clamping member 61 is partially located in the ball plug 53 when entering the slot 58. By rotating the ball plug 53, the clamping member 61 is deflected at a certain angle and is stuck in the slot 58 and cannot be removed.

[0051] It should be mentioned that there is a certain resistance to the rotation of the ball plug 53 and the tube body 51 , and external force needs to be applied to control the rotation of the ball plug 53 to prevent the clamping member 61 from falling off from the clamping slot 58 during use.

[0052] In the filler 1 provided by the present invention, the traction device 3 realizes the displacement of the pulling member 5 and the expansion member 4 by pulling the rope 6. After the pulling force of the traction device 3 is removed, the spring 56 can cause the filler 1 to reset for easy removal. In addition, the ball plug 53 and the ball groove 54 are movably connected, allowing the filler 1 to bend to facilitate adaptation to the deformation of the liquid collecting tube.

[0053] The present invention sets the ropes 6 in sections and connects adjacent ropes 6 through sliders 55. By controlling the ropes 6, multiple sliders 55 can be moved synchronously to achieve the expansion of the filler 1. Moreover, when the ropes 6 move, the distance between adjacent expansion mechanisms remains unchanged, which can maintain the support surface.

[0054] In addition, the protruding ball plug 53 and ball groove 54 of the present invention account for a relatively small proportion of the overall length of the expansion mechanism, which can increase the supporting area for the liquid collecting pipe.

[0055] In some embodiments, the proportion of the ball plug 53 and the ball groove 54 in the overall length of the expansion mechanism can be increased, so that the bending angle of the filler 1 can be increased.

[0056] Those skilled in the art will appreciate that the embodiments of the present invention described above and shown in the accompanying drawings are intended only as examples and are not intended to limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functional and structural principles of the present invention have been demonstrated and illustrated in the embodiments. Any variations or modifications may be made to the embodiments of the present invention without departing from the principles described.
