Description

Technical Field

[0001] This application relates to the field of pipe connections, and in particular to a pre-positioning clamp for a German-made offset clamp. Background Technology

[0002] Currently, hose clamps, also known as hose clamps, are commonly used to secure connections between flexible hoses and rigid pipes, joints, or components, preventing leaks of liquid or gas while also withstanding the pressure of the piping system. Hoses are frequently used in pipeline systems such as oil lines, water lines, and air conditioning lines. They are commonly used to tighten joints, offering good performance, high sealing, and easy installation.

[0003] Most existing pipe clamps consist of a clamp band, bolts, and a housing. The housing is fixed to one end of the clamp band, the bolt is rotatably connected inside the housing, and the other end of the clamp band is inserted into the housing, with the inserted end of the clamp band positioned between the bolt and the other end of the clamp band. The clamp band has teeth that mate with the bolt threads. When using the clamp band, first, move the clamp band to fit over the outside of the pipe. Then, connect the pipe to the connection point, and rotate the bolt inside the housing. The bolt threads drive the teeth of the clamp band. In this process, the rotational motion of the bolt threads is converted into a linear tightening motion of the clamp band, tightening it and thus securing the object to be connected or fixed, achieving functions such as clamping and sealing.

[0004] The existing technical solutions mentioned above have the following drawbacks: the clamps are difficult to fix to the hose during the installation stage, and external force is required to support and fix the clamps in position before tightening can be carried out, resulting in low installation efficiency when fixing pipes with clamps. Utility Model Content

[0005] This application provides a pre-positioning clamp for a German-made offset clamp in order to improve the installation efficiency when fixing pipes with clamps.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0007] A pre-positioning clamp for a German-made pipe clamp includes a clamp band, a bolt, and a housing. The housing is fixedly connected to one end of the clamp band, and the other end of the clamp band is inserted into the housing and slidably connected to the housing. The bolt is located inside the housing. The clamp band has teeth that mesh with the threads of the bolt. The clamp band has a sliding positioning part and a fixed positioning part. The sliding positioning part is slidably connected to the clamp band, and the fixed positioning part is fixedly connected to the clamp band. The sliding positioning part and the fixed positioning part work together to pre-fix the clamp to the pipe.

[0008] Furthermore, the sliding positioning part includes an elastic piece, a connecting piece, and a positioning piece. The elastic piece is located inside the annular clamp band, and both ends of the elastic piece are slidably connected to the clamp band. The connecting piece is disposed on one side of the elastic piece and is fixedly connected to the elastic piece. The positioning piece is fixedly connected to the connecting piece and is used to insert into the side wall of the pipe.

[0009] Furthermore, the connecting piece includes a horizontal plate and a vertical plate, the horizontal plate is fixedly connected to the elastic plate, the vertical plate is perpendicular to the horizontal plate, the vertical plate is fixedly connected to the horizontal plate, and the vertical plate is fixedly connected to the positioning plate.

[0010] Furthermore, the end of the vertical plate near the positioning piece is bent downwards towards the horizontal plate, and the bent vertical plate is used to move the positioning piece to the lower part of the horizontal plate.

[0011] Furthermore, the elastic sheet is also provided with a pipe end positioning device, which includes an mounting plate, an inclined plate, and an end plate. The mounting plate is fixedly connected to the elastic sheet, the inclined plate is arranged parallel to the elastic sheet and fixedly connected to the mounting plate, and the end plate is arranged on the side of the mounting plate away from the elastic sheet. The end plate is used to abut against the end side wall of the pipe.

[0012] Furthermore, the inclined plate and the mounting plate form an angle of 135°-145°.

[0013] Furthermore, an arc-shaped reinforcing rib is provided between the inclined plate and the mounting plate, and the two ends of the reinforcing rib are fixedly connected to the inclined plate and the mounting plate respectively.

[0014] Furthermore, a sliding support is provided between the elastic sheet and the clamping band. Two sliding supports are provided at both ends of the elastic sheet. The sliding supports are used to allow the elastic sheet to slide along the clamping band. Each sliding support includes a connecting block and a positioning block. The positioning block is located on one side of the clamping band that is close to the elastic sheet. The connecting block is located on the side wall of the clamping band. The two ends of the connecting block are fixedly connected to the elastic sheet and the positioning block, respectively.

[0015] Furthermore, the fixing and positioning part includes a fixing plate, a pressure plate, and an inserting plate. The fixing plate is fixedly connected to the pressure plate and the clamping band, respectively. There are two inserting plates, and both inserting plates are fixedly connected to the pressure plate.

[0016] In summary, this application has the following technical effects:

[0017] 1. By setting up sliding positioning parts and fixed positioning parts, when using clamps, the clamps are first pre-fixed to the pipes using the sliding positioning parts and fixed positioning parts. Then, the pipes are placed on the objects to be connected, and the bolts are turned to make the clamps gradually tighten. Since the clamps have been pre-fixed, it is no longer necessary to support the clamps when tightening them, thus improving the installation efficiency when fixing pipes with clamps.

[0018] 2. By setting up a pipe end positioning device, the end piece abuts against the side wall of the pipe end to determine the position of the clamp when it is fitted into the pipe. This allows for quick and accurate determination of the clamp's position on the pipe, preventing the clamp from shifting during pre-fixing and ensuring proper fixation when the pipe is connected to the object to be connected.

[0019] 3. By setting sliding feet, the elastic sheet and the clamping belt can be slidably connected, which improves the convenience of installation of the elastic sheet and the clamping belt. Attached Figure Description

The housing 3 is fixedly connected to one end of the clamp band 1, and the other end of the clamp band 1 is inserted into the housing 3 and slidably connected to the housing 3. The bolt 2 is located inside the housing 3. The clamp band 1 is provided with teeth, which mesh with the threads of the bolt 2. The clamp band 1 is provided with a sliding positioning part 4 and a fixed positioning part 8. The sliding positioning part 4 is slidably connected to the clamp band 1, and the fixed positioning part 8 is fixedly connected to the clamp band 1. The sliding positioning part 4 and the fixed positioning part 8 work together to pre-fix the clamp to the pipeline.

[0027] Reference Figure 2 and Figure 3 The sliding positioning part 4 includes an elastic piece 41, a connecting piece 42, and a positioning piece 43. The elastic piece 41 is located inside the annular clamp band 1, and both ends of the elastic piece 41 are slidably connected to the clamp band 1. The connecting piece 42 is disposed on one side of the elastic piece 41 and is fixedly connected to the elastic piece 41. The positioning piece 43 is fixedly connected to the connecting piece 42 and is used to insert into the side wall of the pipe. In this embodiment, the connecting piece 42 includes a horizontal plate 421 and a vertical plate 422. The horizontal plate 421 is fixedly connected to the elastic piece 41, and the vertical plate 422 is perpendicular to the horizontal plate 421. The vertical plate 422 is fixedly connected to the horizontal plate 421 and the positioning piece 43. The end of the vertical plate 422 near the positioning piece 43 is bent downward toward the horizontal plate 421. The bent vertical plate 422 is used to drive the positioning piece 43 to be located at the lower part of the horizontal plate 421.

[0028] Reference Figure 2 and Figure 3 The elastic sheet 41 is also provided with a pipe end positioning device 5, which includes an installation piece 51, an inclined piece 52, and an end piece 53. The installation piece 51 is fixedly connected to the elastic sheet 41. The inclined piece 52 is arranged parallel to the elastic sheet 41 and is fixedly connected to the installation piece 51. The end piece 53 is located on the side of the installation piece 51 away from the elastic sheet 41 and is used to abut against the end side wall of the pipe. The inclined piece 52 and the installation piece 51 form an angle of 135°-145°. An arc-shaped reinforcing rib 6 is provided between the inclined piece 52 and the installation piece 51. The two ends of the reinforcing rib 6 are fixedly connected to the inclined piece 52 and the installation piece 51, respectively.

[0029] Reference Figure 2 and Figure 3 A sliding support foot 7 is provided between the elastic sheet 41 and the clamp belt 1. Two sliding support feet 7 are provided at both ends of the elastic sheet 41. The sliding support feet 7 are used to make the elastic sheet 41 slide along the clamp belt 1. Each sliding support foot 7 includes a connecting block 71 and a positioning block 72. The positioning block 72 is located on the side of the clamp belt 1 that is close to the elastic sheet 41. The connecting block 71 is provided on the side wall of the clamp belt 1. The two ends of the connecting block 71 are fixedly connected to the elastic sheet 41 and the positioning block 72, respectively.

[0030] Reference Figure 4 The fixed positioning part 8 includes a fixing piece 81, a pressure bearing piece 82 and an inserting piece 83. The fixing piece 81 is fixedly connected to the pressure bearing piece 82 and the clamping band 1 respectively. There are two inserting pieces 83, and both inserting pieces 83 are fixedly connected to the pressure bearing piece 82.

[0031] The implementation principle of the German-made offset clamp pre-positioning clamp in this embodiment is as follows: When using the clamp, firstly, the clamp is moved and fitted onto the outside of the pipe, so that the end piece 53 abuts against the end side wall of the pipe, determining the position of the clamp fitting into the pipe. Then, pressure is applied to the connecting piece 42 using external stamping machinery, causing the connecting piece 42 to drive the positioning piece 43 to insert into the side wall of the pipe. Next, pressure is applied to the bearing piece 82 using external stamping machinery, causing the bearing piece 82 to drive the insertion piece 83 to insert into the side wall of the pipe, thereby completing the pre-fixation of the clamp to the pipe. Then, the pipe is placed on the object to be connected, and the bolt 2 is rotated to gradually tighten the clamp 1. Since the positioning piece 43 and the inserting piece 83 are fixed to the pipe, the clamp 1 at these two points is fixed to the position of the pipe. Therefore, as the clamp 1 tightens, the two ends of the elastic piece 41 gradually bend with the clamp 1, and the two ends of the elastic piece 41 slide relative to the clamp 1. Since the clamp has been pre-fixed, it is no longer necessary to support the clamp when tightening it, thus achieving the purpose of improving the installation efficiency when fixing the pipe with clamps.
