[0028] It should be noted that, in the description of this specification, the terms "upper", "lower", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0029] As shown in the figure, the utility model discloses a quick-install wiring clamp, including a wire clamp body 1, a pressure block 2 and a top shaft 5. The top shaft 5 is swingably mounted on the wire clamp body 1. The wire clamp body 1 is provided with a wiring top plate 6. The pressure block 2 is arranged at a position between the wiring top plate 6 and the top shaft 5. The top shaft 5 can be driven to swing, and the pressure block 2 can be driven by the top shaft 5 to approach or move away from the wiring top plate 6. By driving the top shaft to swing so that the pressure block approaches the wiring top plate of the wire clamp body, the pressure block and the wiring top plate can clamp and fasten the wire to be connected, so as to realize the rapid clamping and installation of the wire clamp. The pressure block is movably arranged so that the distance between the pressure block and the wiring top plate is adjustable, so that the utility model can use wires with different wire diameters, and has a wider range of uses. At the same time, the pressure block is directly driven to approach the wiring top plate through the swing of the top shaft to clamp and fix the wire, which is quick and efficient to operate.

[0030] In this embodiment, an elastic member 3 is also included, and the elastic member in this embodiment is a spring. The elastic member 3 is arranged between the pressing block 2 and the top shaft 5. The pressing block 2 has a tendency to approach the wiring top plate 6 under the elastic force of the elastic member 3. The elastic member has an effective compensation effect on the stress deformation caused by thermal expansion and contraction and creep of the wire during the use of the wire clamp, ensuring the reliability of the wire connection.

[0031] In this embodiment, a telescopic shaft 9 is also included. The top shaft 5 is hinged to the lower part of the wire clamp body 1. One end of the telescopic shaft 9 is connected to the front end of the top shaft 5. The other end of the telescopic shaft 9 is connected to the bottom surface of the pressure block 2 through the elastic member 3. In this embodiment, a guide block 4 and a connecting plate 8 are also included. The guide block 4 is installed at the lower part of the wire clamp body 1. The guide block 4 is provided with a guide channel 401 and a hinged platform 402 from top to bottom. The telescopic shaft 9 is inserted into the guide channel 401 by sliding from top to bottom; the top shaft 5 is hinged to the hinged platform 402. The two ends of the connecting plate 8 are respectively hinged to the front end of the top shaft 5 and the telescopic shaft 9. The top shaft 5 can be driven to swing. The telescopic shaft 9 can make a single-degree-of-freedom reciprocating slide with the swing of the top shaft 5 to drive the pressure block 2 to approach or move away from the wiring top plate 6. The telescopic shaft cooperates with the connecting plate to form a multi-link structure, which makes the transmission of motion smoother. The top shaft is hinged on the junction table to form a lever structure. The swing of the top shaft is converted and transmitted through a multi-link transmission mechanism such as a connecting plate and a telescopic shaft, and converted into a single-degree-of-freedom movement of the pressure block. At the same time, the setting of the guide channel limits the movement direction of the telescopic shaft so that it can only slide up and down in the designed direction, thus ensuring the movement direction of the pressure block.

[0032] In this embodiment, an operating handle is also included, and a sleeve 501 for mounting the operating handle is provided at the rear end of the top shaft 5, and the operating handle is plugged into the sleeve 501 to drive the top shaft 5 to swing. The operating handle can lengthen the power arm length of the top shaft, making the swing of the top shaft easier and more labor-saving.

[0033] In this embodiment, the wiring top plate 6 is an arc-shaped structure, and the top of the pressure block 2 is provided with an arc-shaped lower supporting surface 201, and the bottom surface of the wiring top plate 6 and the lower supporting surface 201 are both provided with tooth-like protrusions. As shown in the figure, the bottom surface of the wiring top plate is the upper supporting surface, which is also an arc-shaped surface. In this embodiment, the clamping is actually achieved by two curved surfaces. Compared with the closed enclosure structure of the conventional wire clamp, the curved clamping structure of the utility model has the advantages of a wider adjustment range and a higher degree of freedom, and can be applied to the continuous connection and branch connection of wires of different wire diameters. The tooth-like protrusions can effectively pierce the oxide layer on the surface of the wire, and better ensure the reliable contact between the wire clamp and the wire.

[0034] In this embodiment, the outer end of the wiring top plate 6 extends outward to form a guide flange 7 with a curved structure. In this embodiment, the wiring top plate 6 is arc-shaped, and combined with the guide flange 7 arranged on the periphery of the wiring top plate 6, the above two form a continuous curved multi-segment curve as a whole, which is more conducive to hanging and installation.

[0035] In this embodiment, a limiting portion for limiting the sliding stroke of the telescopic shaft in the axial direction is provided at the top of the telescopic shaft.

[0036] In this embodiment, the bottom surface of the pressing block 2 is provided with a mounting groove I 202, the top surface of the limiting portion is provided with a mounting groove II 901, and the two ends of the elastic member 3 are respectively correspondingly installed in the mounting groove I 202 and the mounting groove II 901. The provision of the two mounting grooves simultaneously limits the elastic member in the axial direction and radial direction of the elastic member, ensuring the reliability of the installation of the elastic member.

[0037] In this embodiment, there are at least two symmetrically arranged wiring top plates 6, and the pressure blocks 2 are arranged one by one with the wiring top plates 6. As shown in the figure, there are a total of 4 wiring top plates in this embodiment, and there are also four corresponding pressure blocks. Correspondingly, four related components for driving the pressure blocks, such as telescopic shafts, are also correspondingly arranged. This is understandable to technicians in this technical field and will not be repeated here. In this embodiment, components such as hanging plates and pressure plates are arranged on both sides of the wire clamp body, so that when connecting wires or branching the wires, the two wires can be arranged on both sides of the wire clamp body, and the use effect is better.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
