Abstract
Description
Technical Field
[0001] This utility model relates to the field of clamp processing and production, specifically to a single-ear stepless clamp. Background Technology
[0002] Clamps used for sealing in industrial piping systems are crucial connecting components, primarily used to secure and seal pipes, hoses, or joints, ensuring leak-free operation under pressure, temperature, or vibration conditions. Existing clamps are prone to bulging at the lugs, severe warping of the steel strip tail, low structural strength, and are easily pulled off or burst. Utility Model Content
[0003] To solve the above technical problems, a single-ear stepless clamp with stable structure and less prone to lifting of the steel strip tail is provided.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a single-ear stepless clamp, comprising,
[0005] The clamp body has a reinforcing guide tongue extending distally along its length at one end, and a groove matching the reinforcing guide tongue is formed on the surface of the other end of the clamp body. The reinforcing guide tongue and the groove are connected to form an annular clamp.
[0006] The positioning hook is located on the side of the clamp body near the reinforcing guide tongue;
[0007] The opening is located on the side of the clamp body away from the reinforcing guide tongue, and its size matches the positioning hook. The two are hooked together to achieve bending and fixing of the clamp body.
[0008] A limiting hook is provided on the surface of the clamp body. One end of the clamp body is embedded in the limiting hook to fix the end and prevent the end on that side from lifting.
[0009] According to this utility model, the limiting hook is located in the middle of the clamp body, biased towards the positioning hook, and the hook part of the limiting hook and the hook part of the positioning hook are arranged opposite to each other.
[0010] According to this utility model, the distance between the limiting hook and the surface of the clamp body corresponds to the thickness of the clamp body.
[0011] According to this utility model, the slot starts at the middle position of the clamp body and extends to the side away from the positioning hook. The end of the slot and the clamp body form a stepped transition, so that after the clamp body is bent into a ring, the reinforcing guide tongue is inserted into the slot from the inside of the ring. The side with the opening overlaps with the outer surface of the other side, and the end is embedded with the limiting hook.
[0012] According to this utility model, the edge of the opening is further provided with a protruding limiting sleeve with a cavity, and after the positioning hook engages with the opening, the outer side of the positioning hook is covered by the limiting sleeve.
[0013] According to this utility model, two positioning hooks are provided along the length direction of the clamp body, and the number of openings corresponds to the number of positioning hooks, and their positions are matched.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting a limiting hook, the limiting hook is embedded in one end to limit the end, prevent it from lifting, improve the stability of the overall structure, and extend its service life.
[0015] This utility model incorporates mutually matching reinforcing guide tongues and slots, positioning hooks and openings, and multiple positioning structures on the surface of the clamp body. This ensures that the clamp body is structurally stable after being bent into a ring, making it less prone to falling apart and improving its practicality. Attached Figure Description

[0021] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0022] like Figures 1 to 4As shown in the embodiment of this application, a single-ear stepless clamp is disclosed as an important connecting component for sealing in an industrial pipeline system. It includes a clamp body 100, which is a strip of steel. One end of the clamp body 100 has a reinforcing guide tongue 110 extending distally along its length. A protruding positioning hook 120 is formed on the side of the clamp body 100 near the reinforcing guide tongue 110. Correspondingly, an opening 130 matching the positioning hook 120 is opened on the side of the clamp body 100 away from the reinforcing guide tongue 110. After the clamp body 100 is bent into a ring, the positioning hook 120 passes through the opening 130 and hooks onto the edge of the opening 130, thereby achieving the connection and fixation of the positioning hook 120 and the opening 130, that is, achieving the bending and fixing of the clamp body 100.
[0023] Furthermore, to address the issue of edge warping at the clamp body 100, a protruding limiting hook 140 is provided on the surface of the clamp body 100. The limiting hook 140 is located slightly towards the positioning hook 120, and the hook portion of the limiting hook 140 faces the hook portion of the positioning hook 120. After the clamp body 100 is bent, the end of the clamp body 100 near the opening 130 is embedded in the limiting hook 140, thus positioning the end of the clamp body 100 and preventing warping at that end. Preferably, the distance between the limiting hook 140 and the surface of the clamp body 100 corresponds to the thickness of the clamp body 100, ensuring that the end of the clamp body 100 is stably embedded within the distance between the limiting hook 140 and the surface of the clamp body 100, leaving no space for warping.
[0024] The surface of the clamp body 100 also has a slot 150 for accommodating the reinforcing guide tongue 110. The slot 150 starts at the middle position of the clamp body 100 and extends to the side away from the positioning hook 120. The end of the slot 150 forms a stepped transition with the clamp body 100, so that after the clamp body 100 is bent into a ring, the reinforcing guide tongue 110 is inserted into the slot 150 from the inside of the ring, and the side with the opening 130 overlaps with the outer surface of the other side, and the end is embedded in the limiting hook 140.
[0025] In this embodiment, the edge of the opening 130 has a raised, cavity-filled limiting sleeve 131. After the positioning hook 120 engages with the opening 130, the outer side of the positioning hook 120 is covered by the limiting sleeve 131, preventing the positioning hook 120 from lifting and detaching from the opening 130, thus improving the connection stability between the positioning hook 120 and the opening 130. Preferably, two positioning hooks 120 are provided along the length of the clamp body 100, and correspondingly, two openings 130 are provided. Based on the two-point positioning principle, the bent structure is more stable, reducing the positional offset at the overlapping points of the two ends.
[0026] In this embodiment, the width of the reinforcing guide tongue 110 is smaller than the width of the clamp body 100, and the width of the slot 150 matches the width of the reinforcing guide tongue 110, so as to clamp the reinforcing guide tongue 100 and prevent the reinforcing guide tongue 100 from separating from the slot 150.
[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 principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
