Description

Technical Field

[0001] This utility model relates to the field of pipe fitting technology, and in particular to a novel anti-detachment clamp. Background Technology

[0002] (see Figure 1 When the connection between HDPE drainage pipe 1 and pipe fitting 2 is made using a flexible rubber ring 3, there is a possibility that the connection may come apart. For example, at the 90-degree bend when the riser turns into the horizontal pipe, if the position is not properly fixed, the instantaneous impact force when the water flow is large will often cause the joint to open, leading to an accident.

[0003] Therefore, through beneficial exploration and research, the applicant has found a solution to the above problems, and the technical solution to be introduced below is the result of this research. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a new type of anti-loosening sleeve to address the above-mentioned shortcomings and defects of the existing technology.

[0005] The technical problem to be solved by this utility model can be achieved by the following technical solution:

[0006] A novel anti-detachment clamping sleeve is characterized by comprising a clamping sleeve structure fixed at the connection between the fitting and the pipe and used to prevent the fitting and the pipe from being pushed apart by water flow. The clamping sleeve structure includes a first retaining ring and a second retaining ring respectively fitted on the fitting and the pipe, and a metal connecting strip connected to the first retaining ring and the second retaining ring.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0021] See Figures 2 to 3 The present invention discloses a novel anti-detachment clamp, comprising a clamp structure 100 fixed at the connection between the fitting and the pipe and used to prevent the fitting and the pipe from being separated by water flow. In this embodiment, the clamp structure 100 is made of stainless steel. The use of stainless steel can improve the overall strength of the clamp structure 100, making it less likely to be separated when fitted onto the pipe and fitting.

[0022] The clamping structure 100 includes a first clamping ring 110 and a second clamping ring 120 respectively fitted onto the fitting and the pipe, and a metal connecting strip 130 connected to the first clamping ring 110 and the second clamping ring 120. Both ends of the metal connecting strip 130 are welded to the first clamping ring 110 and the second clamping ring 120 respectively. In this embodiment, the diameter of the first clamping ring 110 is larger than the diameter of the second clamping ring 120. The diameters of the first clamping ring 110 and the second clamping ring 120 can be designed according to the actual diameter of the fitting and the pipe.

[0023] To prevent slippage of the ferrule structure on the pipe and fitting, a first anti-slip structure 111 and a second anti-slip structure 121 are respectively provided on the inner walls of the first retaining ring 110 and the second retaining ring 120 to prevent slippage. In this embodiment, one side of the first anti-slip structure 111 and the second anti-slip structure 121 is provided with a first adhesive layer 111a and a second adhesive layer 121a that connect with the first retaining ring 110 and the second retaining ring 120, and the other side of the first anti-slip structure 111a and the second anti-slip structure 121 is provided with a first friction layer 111b and a second friction layer 121b that contact the pipe and fitting. The adhesive on the first adhesive layer 111a and the second adhesive layer 121a is fixed to the inner walls of the first retaining ring 110 and the second retaining ring 120, and the first friction layer 111b and the second friction layer 121b contact the surface of the pipe and fitting to generate friction, which can further enhance the prevention of displacement of the ferrule structure 100.

[0024] To prevent the first and second retaining rings from being forced apart by strong water flow, a locking assembly 200 is provided on the outer wall of the first retaining ring 110 and the outer wall of the second retaining ring 120. In this embodiment, the locking assembly 200 includes a locking sleeve groove 210 on the outer wall of the first retaining ring 110, a locking sleeve rod 220 on the outer wall of the second retaining ring 120, and a rivet 230 passing through the locking sleeve rod 220 and disposed on the outer wall of the second retaining ring 120. The locking sleeve rod 220 is rotatably connected to the rivet 230. The locking sleeve groove 210 is L-shaped and fixed to the outer wall of the first retaining ring 110. The gap between the locking sleeve groove 210 and the outer wall of the first retaining ring 110 provides space for the locking sleeve rod 220 to engage. The locking sleeve rod 220 is rotatably engaged with the locking sleeve groove 210 by the rivet 230.

[0025] To improve the sealing performance of the ferrule structure, a sealing ring 300 is provided between the first retaining ring 110 and the second retaining ring 120 to seal the connection between the fitting and the pipe.

[0026] In use, the first retaining ring 110 and the second retaining ring 120 are respectively fitted onto the pipe fitting and the pipe. The first retaining ring 110 and the second retaining ring 120 are connected by a metal connecting strip 130. When the instantaneous impact force of a large water flow washes over the pipe, the first retaining ring 110 and the second retaining ring 120 are held in place by the metal connecting strip 130 and are not easily pried open. In addition, the inner walls of the first retaining ring 110 and the second retaining ring 120 are provided with a first anti-slip structure 111 and a second anti-slip structure 121, which can prevent the first retaining ring 110 and the second retaining ring 120 from slipping on the contact surface with the pipe fitting and the pipe. In order to further prevent the first retaining ring and the second retaining ring from being pried open by the strong water flow, a locking component 200 is provided on the outer wall of the first retaining ring 110 and the outer wall of the second retaining ring 120. Its operating principle is as described above.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
