Description

Technical Field

[0001] The utility model belongs to the technical field related to wire fixers, and in particular relates to a wire fixer for weak current engineering. Background Art

[0002] A wire clamp is a device used to fix and support wires. It can help wires maintain a certain position and shape and prevent them from loosening or sagging. It is usually made of metal or plastic and has the function of clamping wires. It can be installed on walls, ceilings or other structures. In electrical installation and maintenance, wire clamps are used to fix wires in place to ensure the safety and aesthetics of the wires.

[0003] However, when the existing wire clamps are used to clamp the wires, it is impossible to accurately control the clamping force of the wires, which can easily damage the insulation layer on the surface of the wires, affecting the normal use of the wires. Moreover, when the wire clamps are installed on the ceiling or the top of the wall for use, although they can support the wires, the lines are prone to loosening after long-term use, which will damage the safety and aesthetics of the wires. Therefore, a weak current engineering wire clamp is proposed. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model drives the bidirectional threaded rod to rotate by rotating the rotating disk, and the threaded transmission of the bidirectional threaded rod drives the two sets of sliding bins to move in opposite directions inside the shell, so as to drive the clamping plate to clamp and limit the wires, which can improve the stability of the wires when in use.

[0017] 2. The utility model drives the pushing plate to move in the axial direction of the two-way threaded rod by rotating two sets of screws.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-6 The utility model provides a technical solution: a weak current engineering wire fixer, comprising a mounting plate 1, wherein four groups of through holes are arranged at four corners inside the mounting plate 1, a housing 2 is fixedly connected below the mounting plate 1, and a fixing mechanism for fixing the wires is arranged inside the housing 2.

[0027] In order to facilitate the clamping and fixing of the wires and prevent the wires from loosening and sagging during use, the fixing mechanism has a high safety. The fixing mechanism includes a rotating disk 3, a bidirectional threaded rod 4 is fixedly connected to the top of the rotating disk 3, two sets of sliding bins 5 are threadedly connected to the surface of the bidirectional threaded rod 4, a clamping plate 6 is fixedly connected to the front of the sliding bin 5, and two sets of limit plates 9 are also slidably clamped to the surface of the bidirectional threaded rod 4.

[0028] In order to facilitate the clamping and limiting of wires with larger diameters and provide higher protection for pedestrians and the device itself, the sliding bin 5 is slidably connected to the outer shell 2, and screws 7 are threadedly connected on the left and right sides of the outer shell 2, and one end of the screw 7 is fixedly connected to a push plate 15.

[0029] Furthermore, in order to facilitate the limiting and fixing of wires with larger diameters and improve the safety of wire use, a push rod 10 is provided on one side of the limiting plate 9, and the push rod 10 is slidably connected to the sliding bin 5. A wedge block 11 is fixedly connected to one end of the push rod 10, and a return spring is provided between the push rod 10 and the sliding bin 5.

[0030] Furthermore, it can effectively protect pedestrians and the device itself, reduce the cost of use, and improve the safety of use. A sliding rod 12 is arranged in front of the wedge block 11, and a swinging ball 13 is arranged at one end of the sliding rod 12 through an inclined surface. The swinging ball 13 is rotatably connected to the clamping plate 6 through a pin shaft, and a pulley 14 is rotatably connected to one side of the swinging ball 13.

[0031] Furthermore, in order to facilitate the clamping of the wires, the slide rod 12 is slidably connected to the clamping plate 6, and a reset element is arranged between the slide rod 12 and the swing ball 13 and the clamping plate 6. A limit block 8 is arranged in the middle position of the two sets of limit plates 9, and the limit block 8 is rotatably connected to the bidirectional threaded rod 4, and the limit block 8 is fixedly connected to the mounting plate 1.

[0032] Furthermore, when a wire with a larger diameter sags and becomes loose, the impact force caused by the sag can be effectively reduced, thereby improving the safety of wire use. A groove is provided inside the clamping plate 6, and the pulley 14 and the swing ball 13 rotate at a certain angle inside the groove. The sliding bin 5 and the clamping plate 6 are both made of high-strength materials.

[0033] Furthermore, the limiting plates 9 , the push rods 10 , the wedge blocks 11 and the slide rods 12 are stacked in two groups in front of the housing 2 , and strong tension springs are arranged inside the two groups of limiting plates 9 .

[0034] Furthermore, in order to improve the strength of some parts of the device during use and improve safety, the mounting plate 1 and the outer shell 2 are made of high-strength, wear-resistant aluminum alloy material, and the inner sides of the two sets of clamping plates 6 are provided with anti-slip pads.

[0035] Furthermore, in order to facilitate clamping of the wires, the upper end of the bidirectional threaded rod 4 is rotatably connected to the mounting plate 1, and the threads on the surface of the bidirectional threaded rod 4 are arranged in opposite directions.

[0036] Working principle and use process of the utility model: After the utility model is installed, the staff first fixes the device on the ceiling and the wall by bolts or nails, and then puts the wires into the clamping plate 6 below, and then rotates the rotating disk 3 to drive the two-way threaded rod 4 to rotate. When the two-way threaded rod 4 rotates, the thread transmission will drive the two sets of sliding bins 5 to move toward each other inside the shell 2, thereby driving the two sets of clamping plates 6 to clamp the wires, which can effectively improve the stability of the wires when in use and prevent them from loosening and sagging.

[0037] When it is necessary to clamp a wire with a larger diameter, the screw 7 is rotated to drive the push plate 15 to move in the axial direction of the bidirectional threaded rod 4 inside the shell 2. At this time, the push plate 15 will push the two groups of limit plates 9 to move in opposite directions through the inclined surface. When the limit plate 9 moves, it will drive the wedge block 11 to move inside the sliding bin 5 through the push rod 10, and the wedge block 11 will push the slide bar 12 to slide inside the clamping plate 6 through the inclined surface during the movement. When the slide bar 12 slides, it will apply an extrusion force to the swing ball 13 through the inclined surface, and the swing ball 13 will be squeezed and drive the pulley 14 to flip inside the clamping plate 6 around the pin shaft, so that the two groups of pulleys 14 can clamp the wire at a certain inclination angle, which can not only effectively fix the wire, but also because the wire has a large diameter and a large weight, when the wire is used for a long time, it can prevent the wire from causing damage to the device itself, and protect the device. At the same time, when the wire sags, the setting of the two groups of pulleys 14 can effectively buffer it to avoid the large impact force when it suddenly sags, causing damage to the human body and the house.
