Description

Technical Field

[0001] This utility model relates to a connecting device, and more particularly to a concealed clamp. Background Technology

[0002] Traditional clamp connections typically use clamps with raised protrusions. When connecting pipes or equipment, these protrusions are exposed, making them susceptible to environmental factors such as corrosion and impact, which can lead to clamp damage or connection failure. Furthermore, traditional clamp connections also have the following drawbacks: when maintenance is needed on the connected pipes or equipment, the raised protrusions of the clamp must be located before disassembly, making the process cumbersome. To address these issues, a concealed clamp has been developed. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a concealed clamp to solve the problems pointed out in the background art.

[0004] To achieve the aforementioned objectives of this utility model, the technical solution adopted is as follows:

[0005] A concealed clamp includes a clamp body, which is annular in structure. The clamp body has an opening for easy installation. Two countersunk screw mounting holes and two auxiliary mounting holes are symmetrically provided on both sides of the opening on the clamp body. The countersunk screw mounting holes and auxiliary mounting holes are provided along the radial direction of the clamp body. An annular groove is provided on the inner side of the clamp body. The cross-section of the clamp body is U-shaped.

[0006] As a further improvement of this utility model, the inner side of the clamp body is provided with multiple arc-shaped grooves for easy installation.

[0007] As a further improvement of this utility model, three arc-shaped grooves are evenly provided.

[0008] As a further improvement of this utility model, the countersunk screw mounting hole is located between the mounting auxiliary hole and the opening.

[0009] As a further improvement of this utility model, the included angle between the axes of the two mounting auxiliary holes is 30°.

[0010] As a further improvement of this utility model, the included angle between the axes of the mounting holes of the two countersunk screws is 20°.

[0011] The beneficial effects of this utility model are as follows: Through the design of the annular groove and U-shaped cross-section, the clamp body and the shell to be connected form a concealed fit, avoiding the problem of exposed protrusions in traditional clamps. This effectively reduces damage to the clamp from external environments such as corrosion and impacts, extending its service life. Furthermore, the three uniformly spaced arc-shaped grooves on the inner side of the clamp body reduce its weight and improve flexibility during installation, adapting to different sizes or slightly deformed connecting parts, reducing stress concentration, and preventing material fatigue.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0020] like Figure 1-4As shown, a concealed clamp includes a clamp body 1, which is a ring structure. The clamp body 1 has an opening 2 for easy installation. Two countersunk screw mounting holes 3 and two mounting auxiliary holes 4 are symmetrically opened on both sides of the opening 2. The countersunk screw mounting holes 3 and the mounting auxiliary holes 4 are both opened in the radial direction of the clamp body 1. An annular groove 5 is opened on the inner side of the clamp body 1. The cross-section of the clamp body 1 is U-shaped.

[0021] The inner side of the clamp body 1 is provided with multiple arc-shaped grooves 6 for easy installation.

[0022] The arc-shaped groove 6 is evenly provided in three parts.

[0023] The countersunk screw mounting hole 3 is located between the mounting auxiliary hole 4 and the opening 2.

[0024] The included angle between the axes of the two mounting auxiliary holes 4 is 30°.

[0025] The included angle between the axes of the two countersunk screws installed through hole 3 is 20°.

[0026] In use, the housing to be connected has an annular protrusion that matches the annular groove 5. In use, the hidden clamp is tightened into place on the housing by the cooperation of the clamp wrench and the installation auxiliary hole 4. The housing has a connection hole corresponding to the countersunk screw installation through hole 3. The hidden clamp is fixed on the housing by passing the countersunk screw through hole 3 and the connection hole in sequence through the countersunk screw.
