Description

Technical Field

[0001] This utility model relates to the technical field of pipeline clamping devices, and more specifically to a self-locking pipe clamp. Background Technology

[0002] In building and facility applications, it is often necessary to lay conduits / wire harnesses. To ensure the orderly arrangement of these conduits / wire harnesses, cable trays are typically first created in the area to be laid. Conduit clamps are then used to hold and store the conduits / wire harnesses. Finally, the clamps and the conduits / wire harnesses are placed together into the cable trays, which serve as mounting slots, thus completing the installation. The presence of the clamps effectively secures the conduits / wire harnesses, preventing wear or detachment from the cable trays.

[0003] Commonly available pipe clamps, after the pipe / wire harness is inserted, are usually closed and tightened with bolts or other fasteners before being buried in the installation slot along with the pipe / wire harness. Since bolts require external tools for installation, the efficiency is low, and it is especially inconvenient in space-constrained or batch installation scenarios. Utility Model Content

[0004] The purpose of this invention is to provide a self-locking pipe clamp that can both ensure effective fixation of the pipe clamp relative to the pipe / wire harness and ensure convenient assembly of the pipe clamp.

[0005] To solve the above problems, this utility model provides a self-locking pipe clamp, including a pipe clamp and a self-locking body. The pipe clamp is formed by connecting at least three rods in sequence to form a frame structure, and the pipe clamp has elastic deformation capability. Two of the rods of the pipe clamp are disconnected to form an opening. The rod at one end of the opening is provided with a locking groove, and the rod at the other end of the opening is provided with a locking hook. The locking hook is used to engage with the locking groove to close the opening. The self-locking body is connected to either of the rods at both ends of the opening of the pipe clamp, and the self-locking body has a bent part that protrudes from the outer periphery of the pipe clamp. The self-locking body is used to abut against the wall of the groove when the pipe clamp is inserted into the groove to be installed, thereby pushing the rod where the self-locking body is located closer to the rod at the other end of the opening, so that the locking hook and the locking groove are more tightly engaged.

[0006] Compared with existing technologies, the above solution uses the opening of the pipe clamp to connect the pipe / wire harness, achieving initial clamping. Simultaneously, the self-locking body added to the pipe clamp, with its protruding bent portion relative to the outer periphery of the clamp, pushes the clamp's rod towards the other end of the opening during subsequent insertion into the mounting slot. This causes the locking hook to engage with the locking slot and remain locked, thus achieving automatic locking of the pipe clamp. This significantly improves the firmness and reliability of the clamp's opening after closure and enhances the clamping effect on the pipe / wire harness. Furthermore, since the self-locking lock occurs during the clamp's press-fitting into the mounting slot, no additional installation steps are required, making operation simple and convenient. Compared to existing technologies that involve tightening bolts to close the clamp's latch before inserting it into the mounting slot, this greatly simplifies the operation.

[0007] In an improved embodiment, the two rods of the pipe clamp furthest from the opening are connected by a spring plate. The elastic deformation capability of the pipe clamp is provided by the spring plate, which serves as the main elastic deformation point of the pipe clamp. When the opening of the pipe clamp is opened, the deformation is concentrated, which not only reduces the operating force required to open the pipe clamp, but also reduces the probability of damage to the main body of the pipe clamp.

[0008] In an improved design, both the locking groove and the locking hook are arc-shaped with a spring at their center. The opening of the locking groove faces the locking hook, making the path of the locking hook engaging the locking groove more natural and smooth, further reducing the difficulty and force required to close the opening of the pipe clamp.

[0009] In an improved embodiment, the locking groove wall is provided with a plurality of locking teeth, and the locking hook is provided with a plurality of teeth. The locking teeth engage with the teeth to achieve the engagement between the locking hook and the locking groove. The engagement structure of the locking teeth and teeth can effectively enhance the bonding strength between the locking hook and the locking groove and prevent them from accidentally loosening.

[0010] In an improved design, the pipe clamp is formed by five rods connected in sequence to form a pentagon. The pentagonal shape of the pipe clamp facilitates stress transfer, resulting in a better self-locking effect of the self-locking body on the pipe clamp. Furthermore, the five sides of the pipe clamp can exert uniform pressure on the internal pipeline in five directions, causing the pipeline to undergo a deformation that tends towards a pentagon. This makes it less likely for the pipeline to rotate relative to the pipe clamp after installation, thus achieving a more stable clamping effect on the pipeline.

[0011] In an improved embodiment, the self-locking body is connected to a rod with a locking hook, such that when pressed by the groove wall of the slot to be installed, the self-locking body pushes the rod with the locking hook closer to the rod with the locking groove, making it easier for the locking hook to engage with the locking groove for alignment.

[0012] In an improved embodiment, the self-locking body is a rod-shaped structure with a bent portion. The self-locking body and the rod together form a triangle. This provides good stability, ensuring that the self-locking body can effectively push the rod. Furthermore, the shape of the self-locking body can better adapt to the angle at which the pipe clamp is inserted into the slot to be installed, ensuring smoother insertion of the pipe clamp into the slot and locking of the pipe clamp by the self-locking body.

[0013] In an improved embodiment, the inner peripheral wall of the pipe clamp is provided with circumferentially distributed limiting protrusions. The limiting protrusions can press indentations on the surface of the pipe / wire harness inside the pipe clamp, increasing the frictional resistance between the pipe clamp and the pipe / wire harness, and improving the fixing effect of the pipe clamp on the pipe / wire harness.

[0014] A method for using a self-locking pipe clamp, applied to the self-locking pipe clamp as described above, includes the following steps: First, separate the rods at both ends of the opening of the pipe clamp, and insert the pipe / wire harness into the pipe clamp through the opening. Then, ensuring that the locking hook is aligned with the locking groove, insert the pipe clamp into the slot to be installed, and ensure that the opening of the pipe clamp is located at the opening of the slot to be installed. During this insertion process, due to the abutment of the slot wall against the self-locking body, the self-locking body will push the rod to move closer to the rod at the other end of the opening, so that the locking hook engages with the locking groove and remains locked, achieving a self-locking effect.

[0020] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] Example 1 Please see Figures 1-3 The present invention provides a self-locking pipe clamp according to Embodiment 1, comprising a pipe clamp 1 and a self-locking body 2. The pipe clamp 1 is formed by connecting at least three rods in sequence to form a frame structure, and the pipe clamp 1 has elastic deformation capability. Two of the rods of the pipe clamp 1 are disconnected to form an opening 11. The rod at one end of the opening 11 is provided with a locking groove 12, and the rod at the other end of the opening 11 is provided with a locking hook 13. The locking hook 13 is used to engage with the locking groove 12 to close the opening 11. The self-locking body 2 is connected to either of the rods at both ends of the opening 11 of the pipe clamp 1, and the self-locking body 2 is provided with a bent part 21 that protrudes from the outer periphery of the pipe clamp 1. The self-locking body 2 is used to abut against the wall of the groove 3 when the pipe clamp 1 is inserted into the groove 3 to be installed, thereby pushing the rod of the self-locking body 2 closer to the rod at the other end of the opening 11, so that the locking hook 13 and the locking groove 12 are more tightly engaged.

[0022] Compared with the prior art, in the above solution, the pipe clamp 1 achieves the connection of the pipe / wire harness through the opening 11, realizing the initial clamping of the pipe / wire harness. At the same time, by adding a self-locking body 2 to the pipe clamp 1, since the self-locking body 2 has a bent part 21 protruding relative to the outer periphery of the pipe clamp 1, during the subsequent insertion of the pipe clamp 1 into the groove to be installed 3, the self-locking body 2 will be squeezed by the groove wall of the groove to be installed 3, pushing the rod body to move closer to the rod body at the other end of the opening 11, so that the locking hook 13 engages with the locking groove 12 and remains locked. The self-locking body 2 automatically locks the pipe clamp 1, significantly improving the firmness and reliability of the opening 11 of the pipe clamp 1 after it is closed, and also improving the clamping effect of the pipe clamp 1 on the pipe / wire harness. At the same time, since the self-locking body 2 locks the pipe clamp 1 during the process of pressing the pipe clamp 1 into the installation slot 3, no additional installation steps are required, making the operation simple and convenient. Compared with the existing technology of tightening bolts to close the buckle of the pipe clamp 1 and then inserting the pipe clamp 1 into the installation slot 3, the operation steps are greatly simplified.

[0023] The pipe clamp 1 and the self-locking body 2 are preferably made of nylon and are integrally injection molded. Of course, the pipe clamp 1 can also be made of metal with elastic deformation capability. The two rods of the pipe clamp 1 that are away from the opening 11 are connected by a spring sheet 14. The elastic deformation capability of the pipe clamp 1 is provided by the spring sheet 14. With the spring sheet 14 as the main elastic deformation point of the pipe clamp 1, the deformation can be concentrated when the opening 11 of the pipe clamp 1 is opened. This not only reduces the operating force required to open the pipe clamp 1, but also reduces the probability of damage to the main body of the pipe clamp 1.

[0024] As an improvement to this embodiment, both the locking groove 12 and the locking hook 13 are arc-shaped and the center of the arc is the spring piece 14. The opening of the locking groove 12 is directly opposite the locking hook 13, so that the path of the locking hook 13 into the locking groove 12 is more natural and smooth, further reducing the difficulty of operation and the required force when closing the opening 11 of the pipe clamp 1.

[0025] More specifically, the groove wall of the locking groove 12 is provided with a number of locking teeth 12a, and the locking hook 13 is provided with a number of teeth 13a. The locking teeth 12a engage with the teeth 13a to achieve the engagement between the locking hook 13 and the locking groove 12. The engagement structure of the locking teeth 12a and the teeth 13a can effectively enhance the bonding strength between the locking hook 13 and the locking groove 12 and prevent them from accidentally loosening.

[0026] In this embodiment, the pipe clamp 1 is formed by five rods connected in sequence to form a pentagon. The pentagonal shape of the pipe clamp 1 facilitates stress transmission, resulting in a better self-locking effect of the self-locking body 2 on the pipe clamp 1. Furthermore, the five sides of the pipe clamp 1 can exert uniform pressure on the internal pipeline in five directions, causing the pipeline to undergo a deformation tending towards a pentagon. This makes it less likely for the pipeline to rotate relative to the pipe clamp 1 after installation, achieving a more stable clamping effect on the pipeline. Of course, the pipe clamp 1 can also be formed by six rods connected in sequence to form a hexagon, or eight rods connected in sequence to form an octagon, etc. The specific number can be modified according to the shape of the installation slot 3 and the shape of the pipeline / wire harness.

[0027] In this embodiment, the self-locking body 2 is connected to the rod with the locking hook 13, so that when it is squeezed by the groove wall of the groove to be installed 3, the self-locking body 2 pushes the rod with the locking hook 13 closer to the rod with the locking groove 12, and the locking hook 13 is more easily aligned when it engages with the locking groove 12.

[0028] More specifically, the self-locking body 2 has a rod-shaped structure with a bent portion 21. The self-locking body 2 and the rod body together form a triangle. Thus, on the one hand, the triangular structure has good stability, ensuring that the self-locking body 2 can effectively push the rod body. On the other hand, the shape of the self-locking body 2 can better adapt to the angle at which the pipe clamp 1 is inserted into the slot to be installed 3, ensuring that the insertion of the pipe clamp 1 into the slot to be installed 3 and the locking of the pipe clamp 1 by the self-locking body 2 are smoother.

[0029] As an improvement to this embodiment, the inner peripheral wall of the pipe clamp 1 is provided with a limiting protrusion 15 distributed in the circumferential direction. The limiting protrusion 15 can press an indentation on the surface of the pipe / wire harness inside the pipe clamp 1, increasing the frictional resistance between the pipe clamp 1 and the pipe / wire harness, and improving the fixing effect of the pipe clamp 1 on the pipe / wire harness.

[0030] Example 2 Embodiment 2 of this utility model also provides a method for using a self-locking pipe clamp, applied to the self-locking pipe clamp as in Embodiment 1, including the following steps: First, separate the rods at both ends of the opening 11 of the pipe clamp 1, and insert the pipe / wire harness into the pipe clamp 1 through the opening 11. Then, while ensuring that the locking hook 13 is aligned with the locking groove 12, insert the pipe clamp 1 into the installation groove 3, and ensure that the opening 11 of the pipe clamp 1 is located at the groove opening of the installation groove 3. During this insertion process, due to the abutment of the groove wall of the installation groove 3 against the self-locking body 2, the self-locking body 2 will push the rod to move closer to the rod at the other end of the opening 11, so that the locking hook 13 engages with the locking groove 12 and remains locked, achieving a self-locking effect.

[0031] In addition, the installation slot 3 mentioned in the specific implementation can refer to a standard cabinet cable tray or other slots that need to be set as required; the cross-section of the installation slot 3 can be trapezoidal, rectangular or other shapes, and this design does not limit them.
