Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning accessory production, in particular to a pipeline fixing clamp. Background Art

[0002] In order to monitor the system pressure status, commercial air-conditioning units are equipped with pressure switches on the exhaust pipe and the intake pipe respectively. The exhaust pipe and the intake pipe include a straight pipe and an L-shaped pipe welded to the straight pipe. The high-pressure switch and the low-pressure switch are installed at the pipe mouth of the L-shaped pipe.

[0003] Since the pressure switch has a certain weight and the pressure switch is set at the end of the L-shaped tube, the end of the L-shaped tube is heavier, while the tube body of the L-shaped tube is lighter. Driven by the pressure switch, the L-shaped tube will swing, resulting in the L-shaped tube being unable to be positioned, so that the L-shaped tube cannot be parallel to the straight tube, which easily causes leakage failure at the welding point between the L-shaped tube and the straight tube. The existing technology mainly positions the L-shaped tube and the straight tube manually, but manual positioning is unstable. Summary of the invention

[0004] The utility model aims to avoid the deficiencies in the prior art and provide a pipeline fixing clamp, which can accurately position multiple pipelines according to designated positions, facilitate welding of multiple pipelines according to the designed connection method, and avoid leakage problems in the connections between pipelines.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0010] In some embodiments, the locking member includes a first clamping plate, a second clamping plate and a torsion spring, and one end of the first clamping plate is hingedly connected to one end of the second clamping plate through an axis core;

[0011] The torsion spring comprises a spring body, and torsion arms extend from both ends of the spring body respectively;

[0012] The spring body is sleeved on the shaft core, one end of the first clamping plate and one end of the second clamping plate are respectively supported by the two torsion arms, the other end of the first clamping plate and the other end of the second clamping plate are clamped together to form a clamping end, and the clamping end is clamped to lock the rod body.

[0013] In some embodiments, the inner side surface of the first handle is aligned with the inner side surface of the second handle.

[0014] The outer side surface of the first handle rod faces the inner side surface of the first clamp plate, and the outer side surface of the second handle rod faces the inner side surface of the second clamp plate;

[0016] The first support plate is fixed to the outer side of the first handle, and the second support plate is fixed to the outer side of the second handle.

[0017] In some embodiments, one end of the first support plate body and one end of the second support plate body are close to the clamping end and are respectively connected to the first clamping plate and the second clamping plate, and the other end of the first support plate body and the other end of the second support plate body are far away from the clamping end and are respectively connected to the first handle rod and the second handle rod.

[0018] In some embodiments, the first clamping plate surface and / or the second clamping plate surface at the clamping end are arched toward a side facing away from the rod body to form an arched surface.

[0019] In some embodiments, the shaft core is hinged with a first connecting plate and a second connecting plate, the first clamping plate is hinged to the shaft core through the first connecting plate, and the second clamping plate is hinged to the shaft core through the second connecting plate.

[0020] In some embodiments, the first connecting plate and / or the second connecting plate comprises an upper plate body and a lower plate body, and the upper plate body and the lower plate body are respectively hinged to two ends of the shaft core;

[0021] The spring body is arranged between the upper plate body and the lower plate body.

At this time, the first clamping claw on the head end of the first handle rod and the second clamping claw on the head end of the second handle rod are close to each other, so as to hold the first pipeline. The first clamping claw on the tail end of the first handle rod and the second clamping claw on the tail end of the second handle rod are close to each other, so as to hold the second pipeline. Therefore, the first pipeline and the second pipeline are positioned at the two ends of the connecting rod. By designing the configuration of the rod body, the first pipeline and the second pipeline are aligned according to the set position, and the first pipeline and the second pipeline are accurately positioned, so that the first pipeline and the second pipeline can be accurately welded together, avoiding the problem of welding leakage caused by the first pipeline and the second pipeline being tilted.

[0037] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0038] Since the high-pressure switch and the low-pressure switch have a certain weight, the high-pressure switch and the low-pressure switch will cause the L-shaped tube to swing, resulting in the L-shaped tube being unable to be positioned, so that the L-shaped tube cannot be parallel to the straight tube, which easily causes leakage failure at the welding point between the L-shaped tube and the straight tube. The prior art mainly positions the L-shaped tube and the straight tube manually, but manual positioning is unstable. In view of this technical problem, some embodiments are provided below.

[0039] Example 1

[0040] See also Figures 1 to 4 The pipeline fixing clamp disclosed in this embodiment includes:

[0041] A first positioning arm, the first positioning arm comprises a first handle bar 1, and a first clamping claw 2 is respectively provided at the head end and the tail end of the first handle bar 1;

[0042] Specifically, the first positioning arm has a first handle bar 1 , the configuration of which is used to determine the positioning direction, wherein first clamping jaws 2 are provided on the head end and the tail end of the first handle bar 1 , and the first clamping jaws 2 are used to grasp the pipeline.

[0043] A second positioning arm, the second positioning arm comprises a second handle rod 3, and a first end and a tail end of the second handle rod 3 are respectively provided with second clamping claws 4;

[0044] Specifically, the second positioning arm has a second handle bar 3 , the configuration of which is used to determine the positioning direction, wherein second clamping jaws 4 are provided on the head end and the tail end of the second handle bar 3 , and the second clamping jaws 4 are used to grasp the pipeline.

[0045] Furthermore, the first handle bar 1 and the second handle bar 3 are combined so that the first clamping jaw 2 on the first handle bar 1 and the second clamping jaw 4 on the second handle bar 3 are combined to clamp the pipeline. Since the first clamping jaw 2 and the second clamping jaw 4 are respectively arranged on the first handle bar 1 and the second handle bar 3, the configurations of the first handle bar 1 and the second handle bar 3 are used to determine the relative position of the first clamping jaw 2 and the second clamping jaw 4, thereby determining the relative position of the pipeline on the first clamping jaw 2 and the pipeline on the second clamping jaw 4, thereby achieving the function of positioning the two pipelines. The locking member, the first handle bar 1 and the second handle bar 3 are aligned and locked into a connecting rod 5 through the locking member, so that the first clamping jaw 2 on the head end of the first handle bar 1 and the second clamping jaw 4 on the head end of the second handle bar 3 are close to each other for holding the first pipeline 6;

[0046] Among them, the first clamping jaw 2 and the second clamping jaw 4 located at the head end form the first clamping part of the first pipeline 6; the first clamping jaw 2 and the second clamping jaw 4 located at the tail end form the second clamping part of the second pipeline 7, and the first clamping part and the second clamping part are positioned at both ends of the connecting rod 5.

[0047] That is, the first clamping jaw 2 on the tail end of the first handle rod 1 and the second clamping jaw 4 on the tail end of the second handle rod 3 are close to each other for holding the second pipeline 7 , and the first pipeline 6 and the second pipeline 7 are positioned on both ends of the connecting rod 5 .

[0048] Specifically, the first handle bar 1 and the second handle bar 3 both have a certain length, wherein the first handle bar 1 and the second handle bar 3 are aligned with each other, which means that the first handle bar 1 is aligned with the second handle bar 3 in its length direction, so that the first handle bar 1 and the second handle bar 3 can be assembled into a whole, and at the same time, the first handle bar 1 and the second handle bar 3 actually achieve a clamping action during the assembly process, so that the first clamping jaw 2 and the second clamping jaw 4 are combined to clamp the pipeline. The aligned first handle bar 1 and the second handle bar 3 need to be locked by a locking member to prevent the first handle bar 1 and the second handle bar 3 from shifting.

[0049] Furthermore, after the first pipeline 6 and the second pipeline 7 are positioned, for example, after the first pipeline 6 and the second pipeline 7 are connected and fixed, the pipeline fixing clamp needs to be removed. At this time, the locking piece is unlocked, and the first handle rod 1 and the second handle rod 3 will be separated, that is, the first clamping jaw 2 and the second clamping jaw 4 on the first handle rod 1 will no longer clamp the pipeline, so the pipeline fixing clamp can be easily removed.

[0050] Similarly, when the pipeline fixing clamp needs to be installed on the pipeline, the first handle rod 1 and the second handle rod 3 are first brought close to each other. At this time, the first handle rod 1 and the second handle rod 3 can be aligned and fixed according to the diameter of the pipeline, so that pipelines of any diameter can be fixed by the first handle rod 1 and the second handle rod 3.

[0051] The working principle of the above-mentioned pipeline fixing clamp is as follows: the first handle rod 1 and the second handle rod 3 are aligned and assembled into a rod body through a locking piece, at which time the first clamping jaw 2 on the head end of the first handle rod 1 and the second clamping jaw 4 on the head end of the second handle rod 3 are close to each other, so as to hold the first pipeline 6, and the first clamping jaw 2 on the tail end of the first handle rod 1 and the second clamping jaw 4 on the tail end of the second handle rod 3 are close to each other, so as to hold the second pipeline 7, so that the first pipeline 6 and the second pipeline 7 are positioned at the two ends of the connecting rod 5. By designing the configuration of the rod body, the first pipeline 6 and the second pipeline 7 are aligned according to the set position, and the first pipeline 6 and the second pipeline 7 are accurately positioned, so that the first pipeline 6 and the second pipeline 7 can be accurately welded together, avoiding the first pipeline 6 and the second pipeline 7 from tilting and causing welding leakage. Since the first handle rod 1 and the second handle rod 3 are aligned and locked by the locking piece, when the locking piece needs to be released, the first handle rod 1 and the second handle rod 3 will be separated, so that the pipeline fixing clamp can be smoothly disassembled after multiple pipelines are welded, or the clamping jaws can adapt to pipelines of different radii, making it convenient for the pipeline fixing clamp to clamp the pipeline.

[0052] Example 2

[0053] See also Figures 1 to 3 and Figure 5 In order to further realize that the locking member can conveniently lock or unlock the first handle rod 1 and the second handle rod 3, based on the pipeline fixing clamp disclosed in Example 1, this embodiment also discloses a specific structure of the locking member.

[0054] The locking member comprises a first clamping plate 8, a second clamping plate 9 and a torsion spring 10, one end of the first clamping plate 8 is hingedly connected to one end of the second clamping plate 9 via a shaft core 11;

[0055] Specifically, the tail end of the first clamping plate 8 and the tail end of the second clamping plate 9 are both connected to the shaft core 11 , so the first clamping plate 8 and the second clamping plate 9 can be hingedly connected around the shaft core 11 .

[0056] The torsion spring 10 comprises a spring body 101, and torsion arms 102 extend from both ends of the spring body 101;

[0057] The spring body 101 is sleeved on the shaft core 11, one end of the first clamping plate 8 and one end of the second clamping plate 9 are respectively supported by the two torsion arms 102, and the other end of the first clamping plate 8 and the other end of the second clamping plate 9 are clamped together to form a clamping end 13, and the clamping end 13 is clamped to lock the rod body.

[0058] Specifically, the spring body 101 is sleeved on the shaft core 11. At this time, the torsion arms 102 extending from both ends of the spring body 101 will support the tail end of the first clamping plate 8 and the tail end of the second clamping plate 9. The torsion arms 102 push the tail end of the first clamping plate 8 and the tail end of the second clamping plate 9 outward, so that the head end of the first clamping plate 8 and the head end of the second clamping plate 9 are clamped together to form a clamping end 13. The clamping end 13 is used to clamp the aligned first handle rod 1 and the second handle rod 3. The clamping effect of the clamping end 13 makes the separated first handle rod 1 and the second handle rod 3 locked into a rod body. When the first handle rod 1 and the second handle rod 3 need to be disassembled, the clamping end 13 can be opened by pressing the tail end of the first clamping plate 8 and the tail end of the second clamping plate 9, so that the first handle rod 1 and the second handle rod 3 are unlocked.

[0059] Example 3

[0060] See also Figures 1 to 3 Since the locking member needs to be used to lock the first handle bar 1 and the second handle bar 3, in order to stably install the locking member on the first handle bar 1 and the second handle bar 3, and conveniently realize that the first handle bar 1 and the second handle bar 3 can be locked or unlocked, based on the pipeline fixing clamp disclosed in the above embodiment, this embodiment also discloses how the locking member can be stably installed on the first handle bar 1 and the second handle bar 3, specifically:

[0061] The inner side surface of the first handle rod 1 is aligned with the inner side surface of the second handle rod 3.

[0062] Exemplarily, the first handle rod 1 and the second handle rod 3 are both long strips of sheets, and the inner side surface of the sheet of the first handle rod 1 is aligned with the inner side surface of the sheet of the second handle rod 3 and fit together, wherein the first handle rod 1 and the second handle rod 3 are set as long strips of sheets, which can fit together better and facilitate the fitting connection between the first clamp 2 and the second clamp 4.

[0063] Furthermore, the outer side surface of the first handle rod 1 faces the inner side surface of the first clamping plate 8, and the outer side surface of the second handle rod 3 faces the inner side surface of the second clamping plate 9;

[0064] The inner side surface of the first clamping plate 8 extends out of the first supporting plate body 14, and the inner side surface of the second clamping plate 9 extends out of the second supporting plate body 15;

[0065] The first support plate 14 is fixed to the outer side of the first handle 1 , and the second support plate 15 is fixed to the outer side of the second handle 3 .

[0066] At this time, the first support plate body 14 and the second support plate body 15 respectively connect the first splint 8 and the second splint 9 to the outer side surface of the first handle rod 1 and the outer side surface of the second handle rod 3, so that the first splint 8 and the second splint 9 can be stably installed on the first handle rod 1 and the second handle rod 3 respectively. At the same time, since the first support plate body 14 and the second support plate are only connected to certain parts of the first splint 8 and the second splint 9, this does not affect the clamping effect between the first splint 8 and the second splint 9.

[0067] Example 4

[0068] See also Figures 2-3 Since the first support plate body 14 and the second support plate are connected to the first clamping plate 8 and the second clamping plate 9, in order to minimize the influence of the first support plate body 14 and the second support plate on the first clamping plate 8 and the second clamping plate 9. Based on the pipeline fixing clamp disclosed in the above embodiment, this embodiment further discloses that one end of the first support plate body 14 and one end of the second support plate body 15 are close to the clamping end 13 and are respectively connected to the first clamping plate 8 and the second clamping plate 9, and the other end of the first support plate body 14 and the other end of the second support plate body 15 are far away from the clamping end 13 and are respectively connected to the first handle rod 1 and the second handle rod 3.

[0069] Specifically, the end of the first support plate body 14 connected to the first splint 8 is close to the clamping end 13, the end of the second support plate body 15 connected to the second splint 9 is close to the clamping end 13, and the end of the first support plate body 14 connected to the first handle rod 1 is far away from the clamping end 13, and the end of the second support plate body 15 connected to the second handle rod 3 is far away from the clamping end 13. At this time, the first support plate and the second support plate can, on the one hand, avoid affecting the clamping end 13 as much as possible, and on the other hand, can still play the role of supporting the first splint 8 and the second splint 9.

[0070] Example 5

[0071] See also Figures 1 to 3 and Figure 6 In order to increase the elastic effect and clamping effect of the clamping end 13, based on the pipeline fixing clamp disclosed in the above embodiment, this embodiment also discloses that the first clamping plate 8 and / or the second clamping plate 9 at the clamping end 13 are arched toward the side away from the rod body to form an arched surface.

[0072] Specifically, the board surface of the first clamping plate 8 and / or the board surface of the second clamping plate 9 at the clamping end 13 is arched toward the side away from the rod body to form an arched surface. At this time, the clamping end 13 is clamped on the board surface of the clamping plate only at the end point position. Although the connection area between the clamping end 13 and the board surface is reduced, the end point serves as a fulcrum, so that the clamping end 13 can be easily clamped.

[0073] Furthermore, the shaft core 11 is hinged with a first connecting plate 16 and a second connecting plate 17 , the first clamping plate 8 is hinged to the shaft core 11 through the first connecting plate 16 , and the second clamping plate 9 is hinged to the shaft core 11 through the second connecting plate 17 .

[0074] Since the tail end of the first clamping plate 8 and the tail end of the second clamping plate 9 are both expanded outward, the tail end of the first clamping plate 8 and the tail end of the second clamping plate 9 can be better hinged through the first connecting plate 16 and the second connection.

[0075] Furthermore, the first connecting plate 16 and / or the second connecting plate 17 comprises an upper plate body 18 and a lower plate body 19, and the upper plate body 18 and the lower plate body 19 are respectively hinged to two ends of the shaft core 11;

[0076] The specific structure of the first connecting plate 16 and the second connecting plate 17 is to set an upper plate body 18 and a lower plate body 19, and the upper plate body 18 and the lower plate body 19 are respectively hinged to the two ends of the shaft core 11. At this time, under the interval of the shaft core 11, a space is left between the upper plate body 18 and the lower plate body 19, and the spring body 101 is arranged between the upper plate body 18 and the lower plate body 19 to facilitate fixing the spring body 101.

[0077] Example 6

[0078] See also Figures 1 to 3 According to actual usage, the positioning between multiple pipelines may be different. Based on the pipeline fixing clamp disclosed in Example 1, this embodiment also discloses that the first handle rod 1 and the second handle rod 3 are both linear handle rods. At this time, the first pipeline 6 and the second pipeline 7 can be aligned in a straight line. In actual applications, the first handle rod 1 and the second handle rod 3 can also be other configurations to adapt to different alignment requirements of the pipelines.

[0079] Furthermore, the first clamping jaw 2 and the second clamping jaw 4 are both constructed as semicircular rings. When the first handle rod 1 and the second handle rod 3 are clamped into a connecting rod 5, the first clamping jaw 2 and the second clamping jaw 4 are assembled into a circular clamping opening adapted to the pipeline.

[0080] The first clamping jaw 2 and the second clamping jaw 4 are both constructed as semicircular rings. At this time, when the first clamping jaw 2 and the second clamping jaw 4 are assembled, they can better hold the pipeline.

[0081] Example 7

[0082] See also Figure 7 Based on the pipeline fixing clamp disclosed in Example 1, this embodiment further discloses that the first pipeline 6 is a straight pipe, the second pipeline 7 is an L-shaped pipe, the outer end of a straight pipe section of the L-shaped pipe is provided with a pressure switch and is parallel to the straight pipe, and the outer end of another straight pipe section of the L-shaped pipe is welded to the straight pipe.

[0083] Specifically, when one end of the L-shaped tube needs to be welded to the straight tube, the separated first handle bar 1 and the second handle bar 3 are brought close to each other, and the first clamp 2 and the second clamp 4 clamp the L-shaped tube and the straight tube respectively, so that the L-shaped tube and the straight tube are positioned at both ends of the rod body. After positioning, one end of the L-shaped tube is welded to the straight tube. After welding, the first handle bar 1 and the second handle bar 3 are separated, and at this time, the first clamp 2 and the second clamp 4 release the L-shaped tube and the straight tube respectively.

[0084] Specifically, in actual use, it is determined according to the diameter length of the L-shaped pipe, the diameter length of the straight pipe, and the vertical distance between the L-shaped pipe and the straight pipe used in actual commercial air-conditioning units.

[0085] In actual use, the first clamping opening 20 formed by the first clamping jaw 2 and the second clamping jaw 4 is used to fix the L-shaped tube, and the second clamping opening 21 formed by the first clamping jaw 2 and the second clamping jaw 4 is used to fix the straight tube. Before welding, the straight tube is placed horizontally, and then the L-shaped tube is piped through the positioning hole on the straight tube. The connection part of the L-shaped tube and the straight tube is required to be 90 degrees vertical (this welding method can achieve uniform distribution of solder around the tube wall under the welding flame, preventing the occurrence of uneven distribution of solder causing solder accumulation, insufficient unilateral penetration, solder sinking and cold welding problems). The pipeline fixing clamp of this embodiment is used to fix the L-shaped tube and the straight tube, so that the L-shaped tube connected to the pressure switch is parallel to the straight tube, and the L-shaped tube is required to be tightened with the straight tube, thereby solving the welding abnormality caused by the shaking of the L-shaped tube and the sinking of the pressure switch 22 caused by the ordinary piping method.
