Description

Technical Field

[0001] This utility model relates to the field of building components technology, specifically to an electrical conduit clamp. Background Technology

[0002] In the field of building decoration, pipe clamps are often used to fix electrical conduits, water pipes, and other pipe fittings to light steel supports. Traditional electrical conduit clamps usually consist of a U-shaped clamp body and a pressure block, with the pressure block being driven by bolts to tighten the pipe fittings.

[0003] However, this type of traditional structure has obvious drawbacks. First, during installation, the clamping block lacks an effective guiding and limiting mechanism inside the U-shaped clamp; it is usually simply placed inside or fitted with a large gap. Second, the snap-fit ​​structure of traditional pipe clamps for inserting into supports is poorly designed. Common snap-fits only have an extension on one side. This structure can only achieve initial hooking on one side during installation. During use, due to the force being applied only on one side or asymmetrically, the entire pipe clamp has a torsional tendency around the snap-fit ​​point, making it prone to tilting and resulting in unstable fixation.

[0004] Therefore, it is necessary to design an electrical conduit clamp that is practical, portable, and has uniform force distribution. Utility Model Content

[0005] The purpose of this utility model is to provide an electrical conduit clamp to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electrical conduit clamp, comprising a U-shaped clamp body, the top and side walls of which form an installation space; a pressure block, movably disposed within the installation space of the U-shaped clamp body; a locking mechanism disposed on the top of the U-shaped clamp body, used to drive the pressure block to move toward the opening of the U-shaped clamp body; and a set of buckles, symmetrically connected to both sides of the opening end of the U-shaped clamp body, each buckle having a first extension and a second extension of different lengths at both ends, used for step-by-step engagement with the bent edge of the bracket.

[0007] According to the above technical solution, a sliding guide mechanism is provided between the pressure block and the U-shaped clamp, and the sliding guide mechanism allows the pressure block to slide within the installation space; the sliding guide mechanism includes elongated grooves formed on both sides of the U-shaped clamp and protrusions provided on both sides of the pressure block and cooperating with the elongated grooves.

[0008] According to the above technical solution, the elongated groove is an elliptical groove, which is composed of a rectangular groove in the middle and semi-circular grooves at both ends, and the protrusion is a semi-circular protrusion.

[0009] According to the above technical solution, the locking mechanism includes a threaded hole opened at the top of the U-shaped clamp and a bolt passing through the threaded hole and capable of being screwed to push the pressure block.

[0010] According to the above technical solution, the top of the pressure block is provided with a limiting groove that matches the end of the bolt.

[0011] According to the above technical solution, the bottom of the pressure block is an inwardly concave V-shaped surface, which is used to fit the outer surface of the pipe fitting.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are: (1) By setting a sliding guide mechanism, the pressure block can slide smoothly and stably in the installation space, which is convenient to operate. At the same time, the installation of the pressure block is also simpler and easier, realizing flexible stepless adjustment of the clamping position; the elliptical groove makes it only move along the predetermined path without deflection, and the semi-circular grooves at both ends serve as hard limits to prevent the pressure block from falling off during adjustment or pressing, thus improving the durability and operational safety of the product. (2) By providing an extension, the pipe clamp is subjected to balanced force at two points on the support, eliminating the torsional torque caused by uneven force in traditional single-sided clamping, effectively preventing the pipe clamp from tilting or loosening during use, and ensuring extremely stable and reliable fixing.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-5 The present invention provides a technical solution: an electrical conduit clamp, comprising a U-shaped clamp body 1, the top and side walls of which form an installation space; a pressure block 2, movably disposed within the installation space of the U-shaped clamp body 1; a locking mechanism disposed on the top of the U-shaped clamp body 1, used to drive the pressure block 2 to move toward the opening of the U-shaped clamp body 1; and a set of buckles 3, symmetrically connected to both sides of the opening end of the U-shaped clamp body 1, each buckle 3 having a first extension 31 and a second extension 32 of different lengths at both ends, used for step-by-step engagement with the bent edge of the bracket.

[0016] Specifically, this novel electrical conduit clamp is mainly used in building decoration to quickly and securely install electrical conduits onto supports. The U-shaped clamp body 1 extends downwards from its top and side walls, forming an open mounting space to accommodate the conduit. The pressure block 2 is movably disposed within this mounting space, and its position can be adjusted according to the size of the conduit. Different conduits correspond to different electrical conduit clamps. A locking mechanism is located at the top of the U-shaped clamp body 1. Its function is to generate a downward driving force through twisting or other means, driving the pressure block 2 towards the opening of the U-shaped clamp body 1, thereby clamping the conduit below.

[0017] A set of clips 3 are symmetrically connected to both sides of the open end of the U-shaped clamp 1. Each clip 3 has a first extension 31 and a second extension 32 of different lengths at both ends. During installation, the two first extensions 31 (the longer and larger ends provide stronger support) can be inserted into the bend of the bracket firstly. Then, using this as a fulcrum, the U-shaped clamp 1 is pressed down, which will press the two second extensions 32 (the shorter ends) into the bend of the bracket, completing the engagement. With two extensions, both ends of the clip 3 can bear force, making it more stable than the previous one-end engagement method, which is more prone to tilting.

[0018] Furthermore, the installation process requires no tools and can quickly and reliably fix the pipe clamps to the bracket, greatly facilitating subsequent and final tightening and improving installation efficiency.

[0019] A sliding guide mechanism is provided between the pressure block 2 and the U-shaped clamp 1. The sliding guide mechanism allows the pressure block 2 to slide within the installation space. The sliding guide mechanism includes elongated grooves 11 formed on both sides of the U-shaped clamp 1, and protrusions 21 provided on both sides of the pressure block 2 and cooperating with the elongated grooves 11.

[0020] Specifically, to ensure smooth movement of the pressure block 2 within the U-shaped clamp 1, a sliding guide mechanism is provided between them. A long, narrow groove 11 is formed on each of the two side walls of the U-shaped clamp 1. Correspondingly, protrusions 21, matching the shape of the long, narrow grooves 11, are provided on both sides of the pressure block 2. During assembly, the pressure block 2 is pushed into the U-shaped clamp 1, and the protrusions 21 on both sides slide into the long, narrow grooves 11 on the side walls of the U-shaped clamp 1, thus completing the installation.

[0021] At this time, the protrusion 21 is restricted to move within the internal space of the elongated groove 11. When it is necessary to adjust the position of the pressure block 2, hold both sides of the pressure block 2, and the pressure block 2 can slide along the length of the elongated groove 11 through the protrusions 21 on both sides. The elongated groove 11 guides and restricts the movement trajectory of the protrusion 21, thereby ensuring that the pressure block 2 always moves smoothly within the predetermined installation space without deflection or falling off.

[0022] The elongated groove 11 is an elliptical groove, which is composed of a rectangular groove in the middle and semi-circular grooves at both ends. The protrusion 21 is a semi-circular protrusion 21.

[0023] Specifically, the elongated grooves 11 on both sides of the U-shaped clamp 1 are elliptical grooves. The specific outline of the elliptical groove is formed by a rectangular groove in the middle and semi-circular grooves connecting the two ends of the rectangular groove. At the same time, the protrusions 21 on both sides of the pressure block 2 are specifically semi-circular protrusions, and their radii are adapted to the radii of the semi-circular grooves at the ends of the elliptical groove. After assembly, the semi-circular protrusions 21 of the pressure block 2 are accommodated in the elliptical groove of the U-shaped clamp 1. The cylindrical surface of the semi-circular protrusions 21 mates with the walls of the semi-circular groove and the rectangular groove of the elliptical groove.

[0024] The semi-circular grooves at both ends of the elliptical groove play a crucial role in limiting the semi-circular protrusion 21. When the protrusion 21 slides to either end of the groove, the semi-circular groove wall can effectively prevent it from moving forward, thereby reliably confining the pressure block 2 within the installation space of the U-shaped clamp 1. This prevents the pressure block 2 from coming out of the groove during adjustment or use, greatly improving the reliability and service life of the product.

[0025] The locking mechanism includes a threaded hole 12 on the top of the U-shaped clamp 1, and a bolt that passes through the threaded hole 12 and can be screwed to abut against the push block 2.

[0026] Specifically, during operation, the bolt is screwed into the threaded hole 12 from top to bottom. As the bolt is continuously screwed, its lower end gradually extends downward and eventually abuts against and pushes against the pressure block 2 below it, thereby providing a controllable, vertically downward driving force to the pressure block 2.

[0027] The top of the pressure block 2 is provided with a limiting groove 22 that matches the end of the bolt.

[0028] Specifically, the position of the limiting groove 22 corresponds vertically to the threaded hole 12 at the top of the U-shaped clamp 1. When the bolt is screwed into the threaded hole 12, its lower end (i.e., the force-applying end) will eventually abut against and embed into the interior of this limiting groove 22. The limiting groove 22 provides a clear receiving and limiting space for the end of the bolt, which can effectively prevent the bolt from slipping off the top of the pressure block 2 during the tightening process, ensuring that the applied downward pressure acts vertically on the pressure block 2 and avoiding force deviation.

[0029] The bottom of pressure block 2 has an inwardly recessed V-shaped surface for conforming to the outer surface of the pipe fitting. Specifically, this V-shaped surface consists of two inclined planes that slope downwards from both sides of the bottom of pressure block 2 towards the central axis, forming a continuous, V-shaped groove structure. The contour of this V-shaped surface is used to conform to the outer surface of the pipe fitting below during the clamping process. Compared to a flat bottom surface, the V-shaped surface can better accommodate and cover circular pipe fittings of different diameters. Its inclined structure ensures that when in contact with the outer wall of the pipe fitting, it can transform from "line contact" or "point contact" into two linear contact bands, significantly increasing the effective contact area.

[0030] Working principle: The operator first places a shim on the bracket. At the shim position, align the side of the U-shaped clamp 1 (with the buckle 3 already installed inside the U-shaped clamp 1) with the buckle 3 to the opening of the bracket. First, insert the longer end (first extension 31) of the two buckles 3 into the bend of the bracket. Using this as a fulcrum, press down on the U-shaped clamp 1 to press the two shorter ends (second extension 32) into the bend as well. Thus, the entire pipe clamp can be quickly and smoothly fixed to the bracket without tools.

[0031] Then, the pipe fitting is placed inside the pre-fixed U-shaped clamp 1, that is, through the inside. At this time, the worker can hold both sides of the pressure block 2 and slide it in the elliptical groove of the U-shaped clamp 1 through the semi-circular protrusion 21 on it, so that the V-shaped surface of its bottom is aligned and lightly attached to the top of the pipe fitting.

[0032] After the position is properly adjusted, use a tool to screw the bolt into the threaded hole 12 at the top of the U-shaped clamp 1. When the bolt is screwed down, its end will embed into the limiting groove 22 at the top of the pressure block 2, thereby driving the pressure block 2 to move down stably. The V-shaped surface at the bottom of the pressure block 2 will tightly fit and press the pipe fitting, finally fixing the pipe fitting firmly to the bracket.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
