Detailed Description

The utility model aims at providing a pipeline butt joint assembly so as to facilitate the butt joint and disassembly of pipelines and improve the disassembly and assembly efficiency.

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1, the embodiment of the utility model discloses a pipeline butt joint assembly, which is used for realizing quick connection and disconnection of two pipelines. The pipe docking assembly includes a cartridge 100, a first pipe docking member 200, a second pipe docking member 300, and a compression seal 400.

As shown in fig. 3, the clamping seat 100 includes a first clamping member 102 and a second clamping member 103, and a clamping groove 104 is formed between the first clamping member 102 and the second clamping member 103. The clamping seat 100 can be a clamping seat with an integral structure or a clamping seat with an assembled structure. In an actual application scenario, in order to prevent the movement of the clamping seat 100, the clamping seat 100 may be fixed at a corresponding position by a structure such as a fastener or a positioning member.

As shown in fig. 2, the dimensions of the first pipe butt joint 200 and the second pipe butt joint 300 may be the same or different, and the dimensions of the corresponding pipe butt joints should be designed in connection with the actual application scenario. The first pipe butt joint member 200 and the second pipe butt joint member 300 have the same structural characteristics, and each of the first pipe butt joint member 200 and the second pipe butt joint member 300 comprises a pipe portion 201 and a clamping portion 202 arranged at one end of the pipe portion 201, and it should be noted that the first pipe butt joint member 200 and the second pipe butt joint member 300 each have a hole penetrating along an axial direction so that a medium can pass through.

In order to enable the clamping portion 202 to be embedded into the clamping groove 104, the clamping portion 202 needs to be protruded outside the pipe portion 201, the clamping portion 202 and the pipe portion 201 may be coaxially arranged and have a cylindrical structure, and of course, the external contour of the clamping portion 202 may also have other shapes, such as an ellipse, a polygon, etc., so long as the clamping portion is protruded outside the pipe portion 201, so that the clamping portion can be embedded into the clamping groove 104. The pipe portion 201 may be a pipe to be abutted, or may be a pipe joint spliced with a pipe to be abutted, and a corresponding pipe may be spliced on the pipe portion 201.

During butt joint, the clamping parts 202 of the first pipe butt joint piece 200 and the second pipe butt joint piece 300 are arranged oppositely to form an alignment clamping assembly, the clamping parts 202 of the first pipe butt joint piece 200 and the second pipe butt joint piece 300 need to be clamped into the clamping grooves 104 at the same time, and meanwhile, the two pipe butt joint pieces are communicated through the opposite arrangement (namely butt joint) of the clamping parts 202 of the two pipe butt joint pieces. The alignment clamping assembly formed after the two clamping parts 202 are butted is used for being embedded in the clamping groove 104, and the alignment clamping assembly is pressed under the action of the clamping groove 104.

As shown in fig. 1 and 4, the compression seal 400 is configured to be disposed between the clamping portions 202 of the first pipe butt joint 200 and the second pipe butt joint 300 when the first pipe butt joint 200 and the second pipe butt joint 300 are in butt joint, and the compression seal 400 not only can seal the alignment surfaces of the two clamping portions 202 to prevent leakage of medium at the joint therebetween, but also can maintain the clamping force of the alignment clamping assembly in the clamping groove 104 due to the elastic action thereof.

The sum of the thicknesses of the clamping portions 202 of the first and second pipe abutments 200 and 300 is less than the width of the clamping slot 104 so that the aligned clamping assembly can be embedded within the clamping slot 104. The sum of the thicknesses of the clamping portion 202 and the compression seal 400 of the first pipe butt joint member 200 and the second pipe butt joint member 300 is larger than the width of the clamping groove 104, so that after the aligned clamping assembly can be embedded into the clamping groove 104, the compression seal 400 can be compressed, thereby ensuring the sealing of the joint, and simultaneously generating elastic force due to deformation, and maintaining the sealing effect and the clamping force.

It should be noted that, the clamping groove 104 may be a groove with an equal width along the depth direction, that is, the clamping force of the alignment clamping assembly at any position of the clamping groove 104 is equal or similar. Of course, the clamping groove 104 may be a groove with a width gradually reduced from the opening side to the groove bottom, and the side wall of the alignment clamping assembly, which is used for being attached to the side wall of the clamping groove 104, and the side wall of the clamping groove 104 have the same inclination angle. The clamping force of the alignment clamping assembly at any position of the clamping groove 104 is unequal, and as the embedding depth increases, the clamping force becomes larger, and a person skilled in the art can set the depth of the alignment clamping assembly in the clamping groove 104 according to the requirements.

According to the pipeline butt joint assembly provided by the utility model, the first clamping piece 102 and the second clamping piece 103 are arranged on the clamping seat 100, so that the clamping groove 104 is formed between the first clamping piece 102 and the second clamping piece 103, and the first clamping piece 102 and the second clamping piece 103 are equivalent to two side walls of the clamping groove 104. The first pipe interface 200 and the second pipe interface 300 each have a clamping portion 202. When the first pipe butt joint piece 200 and the second pipe butt joint piece 300 are required to be in butt joint communication, only the clamping parts 202 of the first pipe butt joint piece 200 and the second pipe butt joint piece 300 are required to be arranged oppositely and placed in the clamping groove 104, and the side walls of the clamping groove 104 compress the two clamping parts 202, so that the compression seal piece 400 is compressed and sealed at the joint of the two clamping parts 202.

According to the utility model, one compression sealing element 400 is clamped by two pipeline butt-joint elements, and is pressed and plugged into the clamping groove 104 of the clamping seat 100, so that the installation butt-joint is realized, and the pipeline butt-joint elements are directly lifted out of the clamping groove 104 of the clamping seat 100 during the disassembly, so that the disassembly is completed. The two pipelines are directly fixed on one clamping seat 100 through the matched pipeline butt joint part and the compression sealing part 400 respectively, so that the butt joint and the sealing are realized, and the disassembly and the assembly are very convenient. The butt joint scheme of the pipeline butt joint assembly provided by the utility model has the advantages of lower part cost, simple structure, convenient installation and disassembly by using the slot clamping, and no limitation to the type and the installation direction of the slot, effectively shortens the disassembly time and improves the disassembly efficiency.

As shown in fig. 3, in order to increase the depth of the alignment clamping assembly embedded in the clamping groove 104, a first pipe relief groove 105 penetrating through the wall thickness is provided on the first clamping member 102, and a second pipe relief groove 106 penetrating through the wall thickness is provided on the second clamping member 103. The first pipe relief groove 105 is configured to cooperate with the pipe portion 201 of the first pipe butt joint 200, so that the width of the first pipe relief groove 105 is not smaller than the outer diameter of the pipe portion 201 of the first pipe butt joint 200, so as to avoid interference between the first clamping member 102 and the pipe portion 201 of the first pipe butt joint 200, and influence the depth of the clamping portion 202 of the first pipe butt joint 200 embedded in the clamping groove 104.

Similarly, the second pipe abdication groove 106 is configured to cooperate with the pipe portion 201 of the second pipe butt joint 300, so that the width of the second pipe abdication groove 106 should not be smaller than the outer diameter of the pipe portion 201 of the second pipe butt joint 300, so as to avoid interference between the second clamping piece 103 and the pipe portion 201 of the second pipe butt joint 300, and influence the depth of the clamping portion 202 of the second pipe butt joint 300 embedded in the clamping groove 104.

Further, the depth of the first pipe relief groove 105 is greater than the diameter of the pipe portion 201 of the first pipe dock 200 such that the pipe portion 201 of the first pipe dock 200 can be fully embedded within the first pipe relief groove 105. The depth of the second pipe relief groove 106 is greater than the diameter of the pipe portion 201 of the second pipe dock 300 such that the pipe portion 201 of the second pipe dock 300 can be fully embedded within the second pipe relief groove 106.

It should be noted that, the depths of the first pipe relief groove 105 and the second pipe relief groove 106 are as deep as possible, so that the alignment clamping assembly can be completely embedded into the clamping groove 104. Thus, the clamping groove 104 can be ensured to generate more stable and reliable clamping force for the alignment clamping assembly, and any position of the alignment clamping assembly can be ensured to be clamped by the clamping groove 104.

In order to ensure that one clamping seat 100 can simultaneously complete the butt joint of a plurality of pipelines, in an embodiment of the present utility model, a plurality of first pipeline yielding grooves 105 are arranged on the first clamping member 102 at intervals, and a plurality of second pipeline yielding grooves 106 corresponding to the first pipeline yielding grooves 105 one to one are arranged on the second clamping member 103 at intervals. The first pipe relief groove 105 and the second pipe relief groove 106 are arranged at intervals along the extending direction of the clamping groove 104, so that the butt joint of a plurality of pipes can be completed simultaneously in the extending direction of the clamping groove 104. The widths of the first pipe abdicating grooves 105 and the second pipe abdicating grooves 106 are different, so that the butt joint of pipes with different sizes can be completed.

As shown in fig. 2, further, the clamping portion 202 has a disc structure coaxially arranged with the pipe portion 201, and the outer diameter of the clamping portion 202 is larger than the outer diameter of the pipe portion 201. The end surface of the clamping part 202 facing away from the pipe part 201 is provided with a seal embedding groove 203, the seal embedding groove 203 is used for embedding the compression seal 400, and the depth of the seal embedding groove 203 is less than half the thickness of the compression seal 400. In this embodiment, by providing the seal insertion groove 203 on the end surface of the clamping portion 202, the compression seal 400 can be inserted into the seal insertion groove 203, so as to position the compression seal 400, and prevent the compression seal 400 from moving between the two clamping portions 202 when the clamping portion 202 is inserted into the clamping groove 104, thereby affecting the sealing effect.

Further, the seal insertion groove 203 is an annular groove, and the compression seal 400 is a seal ring sleeved in the annular groove. That is, an outer ring wall and an inner ring wall are provided on the end face of the engaging portion 202, and the annular groove is formed between the outer ring wall and the inner ring wall, and the compression seal 400 is fitted in the annular groove. The outer ring wall of the clamping portion 202 may be coplanar with the outer circumferential surface of the clamping portion 202, and the inner ring wall may be disposed around the hole through which the medium flows. The heights of the outer ring wall and the inner ring wall should not be too high as long as the displacement of the compression seal 400 can be restricted without impeding the compression seal 400 from being compressively deformed.

As shown in fig. 4, the pipe portion 201 has a first hole section, and the click-on portion 202 has a second hole section 204 communicating with the first hole section, the diameter of the first hole section being larger than the diameter of the second hole section 204. The pipe portion 201 and the engaging portion 202 may have different functions and different purposes, and thus may have different apertures. The pipe section 201 functions to interface with other pipes, thus requiring a larger aperture; the clamping portion 202 is used for realizing the butt joint, and the compression seal 400 needs to be arranged at the section, so that the diameter of the second hole section 204 is designed to be smaller than that of the first hole section in order to prevent the second hole section 204 at the clamping portion 202 from being blocked by the compression seal 400.

As shown in fig. 3, the open side of the clamping groove 104 is a flaring groove structure, and the groove width of the flaring groove structure gradually decreases from the open side of the clamping groove 104 to the groove bottom. Specifically, a chamfer structure can be arranged at the end parts of the first clamping piece 102 and the second clamping piece 103, and the chamfer structure forms the flaring groove structure so as to increase the width of the opening groove 104, and the flaring groove structure plays a guiding role, so that the alignment clamping assembly can be rapidly clamped into the opening groove 104.

In an embodiment of the present utility model, the card holder 100 further includes a mounting portion 101, where the mounting portion 101 is configured to be mounted to a position to be mounted. Corresponding fastening holes can be formed in the mounting portion 101 to facilitate installation in cooperation with fasteners.

After the alignment clamping assembly is clamped into the clamping groove 104 from the opening side of the clamping groove 104, in order to prevent the alignment clamping assembly from being separated from the clamping groove 104 under the action of external force, in the present embodiment, a cover plate 500 is added on the basis of the above embodiment. As shown in fig. 5 to 7, a cover plate 500 is detachably fixed to at least one of the first clamping member 102 and the second clamping member 103, and the cover plate 500 is used for covering the opening side of the clamping groove 104.

In assembling the alignment clip assembly, the cover plate 500 needs to be removed to expose the open side of the clip groove 104, then the alignment clip assembly is inserted into the clip groove 104 through the open side, and then the cover plate 500 is mounted. The cover plate 500 may be detachably fixed to the clamping seat 100 by using the fastener 600, for example, a threaded hole 107 may be formed at the top of at least one of the first clamping member 102 and the second clamping member 103, and an optical hole may be formed in the cover plate 500, and the fastener 600 passes through the optical hole in the cover plate 500 and is screwed onto the threaded hole 107 of the clamping seat 100 to fix the cover plate 500. Since the opening side of the locking groove 104 is blocked, a large force is not required, and the cover 500 may be fixed to one of the first locking member 102 and the second locking member 103 for easy assembly and disassembly. It will be appreciated by those skilled in the art that the cover 500 may be fixed to both the first clamping member 102 and the second clamping member 103, so as to obtain a more stable limiting effect.
