Description

Technical Field

[0001] The utility model belongs to the technical field of cables, and in particular relates to a cable limiting mechanism. Background Art

[0002] Cable is a device for transmitting electric energy or signals, usually composed of several or several groups of wires. When installing cables, they are usually laid through cable trays. Due to the uncertainty of laying cables, some external environments do not use and install cable trays, so the cables are exposed and need to be limited and fixed by limit mechanisms such as buckles.

[0003] Most existing cable limiting mechanisms press the cable through an arc-shaped bracket, and then fix the bracket to the building through bolts. This type of limiting mechanism is easy to scratch the outer wall of the cable when the cable is pulled, and cannot adapt to cables of different thicknesses, so it has low practicality. Utility Model Content

[0004] The purpose of the utility model is to provide a cable limiting mechanism with a simple structure and easy installation. The cable can be clamped between two rollers to protect the cable when it is pulled. The limiting mechanism is easy to open and close, and can limit cables of different thicknesses. The utility model has strong practicality and is suitable for promotion.

[0005] The utility model provides the following technical scheme: a cable limiting mechanism comprises a bottom plate and an upper arc plate, wherein a first vertical plate is fixedly provided with symmetrical first and second sides on the upper surface of the bottom plate, the first vertical plate is installed with a first clamping wheel through a rotating shaft, the first clamping wheel is provided with a first clamping groove which is concave and has a circular arc cross section, and two mounting cylinders are fixedly provided at diagonal positions on the upper surface of the bottom plate, the upper arc plate is provided with a sleeve plate corresponding to the mounting sleeve, a connecting column is penetrated through the sleeve plate, the top of the connecting column is clamped on the sleeve plate and is rotatably connected to the sleeve, a pushing thread is provided on the outer wall of the lower section of the connecting column, the connecting column is inserted into the mounting cylinder and is threadedly connected to the sleeve, and second vertical plates are fixedly provided at the positions on both sides of the upper arc plate corresponding to the first clamping wheel, the second vertical plate is installed with a second clamping wheel through a rotating shaft, the second clamping wheel is provided with a second clamping groove which is concave and has a circular arc cross section, and the first clamping groove is positioned opposite to the second clamping groove.

[0006] Preferably, the upper arc plate is provided with a connecting groove at the sleeve plate, the sleeve plate is fixedly provided with a connecting plate in the connecting groove, a transverse sliding groove is provided on the connecting plate, the connecting groove is fixedly provided with a central axis passing through the sliding groove, the central axis is slidably connected to the connecting groove, both sides of the connecting plate are fitted against the side walls of the connecting groove, and there is a gap between the top of the connecting plate and the connecting groove.

[0007] Preferably, fixing plates with threaded holes are fixedly provided on both sides of the bottom plate.

[0008] Preferably, friction lines are provided on the side wall above the connecting column.

[0009] The utility model has the following beneficial effects: the structure is simple and easy to install. The cable can be clamped between the two rollers to protect the cable when it is pulled out. The limit mechanism is easy to open and close. The cable can be limited to cables of different thicknesses. The utility model has strong practicality. The details are as follows:

[0010] (1) The utility model is provided with a base plate. When the device is installed, the base plate is fixed to the building by bolts, and the cable is clamped at the first clamping groove of the first clamping wheel. At this time, the upper arc plate is installed, and the connecting columns at the diagonal positions of the upper arc plate are aligned with the installation tube. The two connecting columns are rotated at the same time through the friction pattern so that the lower ends of the connecting columns are inserted into the installation tube through the push thread. After the second clamping groove of the second clamping wheel is clamped on the cable, the cable can be fixed. When the cable is pulled, it slides between the first clamping groove and the second clamping groove, and the first clamping wheel and the second clamping wheel also slide accordingly, so that the cable can slide in the limiting mechanism.

[0011] (2) The utility model is provided with a connecting column. When the cable is clamped by the second clamping wheel, the two connecting columns are rotated simultaneously by the friction pattern. Since it is a manual rotation, the two connecting columns cannot rotate at the same speed. During this process, the sleeve plate is offset and the central axis slides on the connecting groove to provide a misalignment space. After the two connecting columns are tightened, the second clamping groove can be clamped on the cable. It can be suitable for cables of different thicknesses, and the clamping and releasing of the cable can be achieved by rotating the connecting column. BRIEF DESCRIPTION OF THE DRAWINGS
