Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle accessories and relates to a pipe clamp. Background Art

[0002] A pipe clamp is a simple device for clamping and fixing pipe fittings and is widely used. An ordinary pipe clamp generally includes two semi-circular clamping plates. Both ends of the clamping plates are provided with protruding arms. The two clamping plates are butted and the two pairs of protruding arms are respectively fixedly connected by bolts and nuts. The pipe fitting is fixed between the two clamping plates.

[0003] There is also a kind of pipe clamp, such as a pipe clamp disclosed in Chinese patent document [Application No.: CN202022788763.0, Publication No.: CN214189885U], which includes a fixed locking ring. Symmetrically and fixedly connected to the opening of the outer wall of the fixed locking ring are two connecting blocks. A circular through hole is opened in the middle of the two connecting blocks, and a long screw rod is slidably inserted through the circular through hole of the two connecting blocks. One end of the long screw rod is fixedly connected with a rotating block, and the other end of the long screw rod is threadedly inserted and connected with a fixed nut. The pipe fitting is inserted into the fixed locking ring. By rotating the long screw rod, the two connecting blocks approach each other, and the fixed locking ring tightens to hold the pipe fitting. During the rotation of the long screw rod, the rotating block and the fixed nut respectively abut against the two connecting blocks, and the two connecting blocks are prone to deformation under force, resulting in the pipe clamp being unable to be used normally. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a pipe clamp for the above problems existing in the prior art, and the technical problem to be solved is how to improve the structural stability of the pipe clamp during use.

[0005] The purpose of the utility model can be achieved by the following technical solutions:

[0006] A pipe clamp includes a C-shaped clamping ring, a bolt and a nut. Both ends of the clamping ring have fixed arms. The rod part of the bolt passes through the two fixed arms and is threadedly connected with the nut. It is characterized in that each fixed arm is provided with a convex edge protruding towards the other fixed arm. Each convex edge is arranged along the edge of the corresponding fixed arm, and each convex edge has an abutting surface for abutting against the pipe fitting.

[0007] When using the pipe clamp, insert the pipe fitting into the clamping ring, and then rotate the bolt or nut to make the two fixed arms approach each other until the clamping ring clamps the pipe fitting. At this time, the abutting surface abuts against the pipe fitting. Since the convex edge is arranged along the edge of the fixed arm and protrudes, it has the function of a reinforcing rib, improving the structural strength of the fixed arm and making the pipe clamp structure stable; the setting of the abutting surface can not only increase the contact area between the pipe clamp and the pipe fitting, making the fixation between the pipe clamp and the pipe fitting stable, but also has a limiting effect on the fixed arm, preventing the two fixed arms from approaching too much and causing a large increase in force, and preventing the two fixed arms from deforming due to excessive force, thus improving the structural stability of the pipe clamp during use. Therefore, this pipe clamp can improve the structural stability during use.

[0008] In the above-mentioned pipe clamp, each convex edge includes side convex parts located on both sides of the fixed arm and end convex parts connected between the two side convex parts. That is to say, each convex edge is U-shaped, which can further improve the function of the convex edge as a reinforcing rib, thereby improving the structural stability of the pipe clamp during use.

[0009] In the above-mentioned pipe clamp, the abutting surface is provided on each side convex part. This setting increases the number and position of the abutting surfaces, can further increase the contact area between the convex edge and the pipe fitting, make the fixation between the pipe clamp and the pipe fitting stable, and at the same time further increases the limiting points, ensuring the limiting effect of the convex edge, preventing the two fixed arms from approaching too much and causing a large increase in force, and preventing the two fixed arms from deforming due to excessive force, thus improving the structural stability of the pipe clamp during use.

[0010] In the above-mentioned pipe clamp, the end convex part is arc-shaped. The arc shape can improve the structural strength at the end of the fixed arm and make the pipe clamp structure stable.

[0011] In the above-mentioned pipe clamp, each convex edge has a protrusion protruding towards the other convex edge, and a part of the abutting surface is located on the protrusion. The protrusion can increase the area of the abutting surface, thereby increasing the contact area between the pipe clamp and the pipe fitting and making the fixation between the pipe clamp and the pipe fitting stable.

[0012] In the above-mentioned pipe clamp, each fixed arm is provided with a through hole for the bolt to pass through, and a convex platform protrudes at the orifice of the through hole on the surface of each fixed arm facing away from the other fixed arm. The convex platform can increase the thickness of the fixed arm, thereby improving the structural strength at the through hole of the fixed arm.

[0013] Compared with the prior art, the present utility model has the following advantages:

[0014] On the fixed arm of the pipe clamp, a convex edge is arranged along the edge of the fixed arm, and the convex edge has an abutting surface that abuts against the pipe fitting, improving the structural strength of the fixed arm of the pipe clamp, increasing the contact area between the pipe clamp and the pipe fitting, and limiting the displacement of the fixed arms approaching each other, preventing the fixed arms from deforming due to excessive force, thereby improving the structural stability of the pipe clamp during use.

Detailed Description of the Preferred Embodiments

[0020] The following are specific embodiments of the present invention and, in conjunction with the accompanying drawings, further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0021] As Figure 1 and Figure 2 shown, a pipe clamp includes a C-shaped clamping ring 1, a bolt 2 and a nut 3. Both ends of the clamping ring 1 have fixed arms 1a, and the rod portion of the bolt 2 passes through the two fixed arms 1a and is threadedly connected to the nut 3. Each fixed arm 1a is respectively provided with a flange 1b protruding towards the other fixed arm 1a. Each flange 1b is respectively arranged along the edge of the corresponding fixed arm 1a, and each flange 1b has an abutting surface 1b1 for abutting against the pipe fitting 4.

[0022] Combined with Figure 3 and Figure 4 shown, each flange 1b includes side convex parts 1b2 located on both sides of the fixed arm 1a and an end convex part 1b3 connecting the two side convex parts 1b2. An abutting surface 1b1 is provided on the surface of each side convex part 1b2 facing away from the end convex part 1b3, and the end convex part 1b3 is arc-shaped. Each side convex part 1b2 has a protrusion 1b4 protruding towards the other fixed arm 1a, and a part of the abutting surface 1b1 is located on the protrusion 1b4. Each fixed arm 1a is provided with a through hole 1a1 for the bolt 2 to pass through, and a protruding boss 1a2 is provided at the orifice of the through hole 1a1 on the surface of each fixed arm 1a facing away from the other fixed arm 1a.

[0023] When using the pipe clamp, insert the pipe fitting 4 into the clamping ring 1, and then rotate the bolt 2 or the nut 3 to make the two fixed arms 1a approach each other until the clamping ring 1 clamps the pipe fitting 4. At this time, the abutting surface 1b1 abuts against the pipe fitting 4, and the head of the bolt 2 and the nut 3 respectively abut against the two bosses 1a2. Since the convex edge 1b is arranged along the edge of the fixed arm 1a and protrudes towards the other fixed arm 1a, it has the function of a reinforcing rib, improving the structural strength of the fixed arm 1a and making the pipe clamp structure stable; the setting of the abutting surface 1b1 can not only increase the contact area between the pipe clamp and the pipe fitting 4, making the fixation between the pipe clamp and the pipe fitting 4 stable, but also has a limiting effect on the fixed arm 1a, preventing the two fixed arms 1a from approaching too much and causing a large increase in force, and preventing the two fixed arms 1a from deforming due to excessive force, thus improving the structural stability of the pipe clamp during use. Therefore, this pipe clamp can improve the structural stability during use.
