Technical Field

[0001] The invention relates to the technical field of wire hanging racks, in particular to an automatically retractable wire hanging rack. Background Art

[0002] Patent No. CN115504333B discloses a fixed wire hanging rack, which relates to the technical field of wire hanging racks, including a support rod, both ends of the support rod are provided with a movable seat, and the support rod is connected to the movable seat through a disassembly mechanism, and a guide rail is provided on the outside of the movable seat, and the movable seat is connected to the guide rail through a damping mechanism. The present invention is provided with a support rod and a winding plate, and the belts and cables are wound on the surface of the winding plate, which can realize the rapid storage of the belts and cables, avoid the belts and cables from being scattered on the ground and tripping the passing staff, and avoid facilitating the next use; a disassembly mechanism is provided, so that the first connecting seats at both ends of the support rod are respectively aligned with the two second connecting seats, and by toggling the paddle, the connecting piece is driven to perform a circular motion until one end of the connecting piece enters the first slide groove, so that the first connecting seat and the second connecting seat can be fixedly connected, thereby quickly completing the installation of the support rod.

[0003] In today's digital age, various cables (such as optical cables, optoelectronic composite cables, soft jumper cables, network cables, etc.) are widely used in government and enterprises, homes, offices, factories, schools, computer rooms and other places. In the production process of wiring harness products such as optical jumper cables for computer rooms, remote optical cable assemblies for base stations, and optoelectronic composite cable assemblies for FTTR system communications, there are often many cables that need to be divided into multiple cables before processing and production, and there will be specifications of different lengths. These cables will not be processed immediately after cutting. The messy stacking of cables not only affects the appearance, but also easily leads to cable damage, unclear entanglement, and difficulty in finding.

[0004] Most of the existing cable hangers are of fixed size and cannot be flexibly adjusted according to the number of cables, usage space or production requirements, and cannot meet diverse usage needs. When there are many cables, the fixed-size cable hanger may not be able to accommodate them due to insufficient capacity. In some environments with limited space, an overly large cable hanger will cause a waste of space. At the same time, the cables cannot be bundled and fixed for later transportation, so they may fall off during transportation.

[0005] Therefore, a kind of automatically retractable wire hanging rack is needed to solve the above problems. Summary of the invention

[0006] The problem to be solved by the present invention is that most of the existing cable hanging racks are of fixed size and cannot be flexibly adjusted according to the number of cables, usage space or production requirements, and cannot meet diverse usage needs. When there are many cables, the cable hanging rack of fixed size may not be able to accommodate them due to insufficient capacity, and in some environments with limited space, an overly large cable hanging rack will cause a waste of space; at the same time, the cables cannot be bundled and fixed for later transportation, so there is a possibility of them falling off during transportation.

[0007] In order to solve the above technical problems, the technical solution of the present invention is: an automatically retractable wire hanging rack, including a base, the middle position of the top of the base is connected to the lifting rod, the top of the lifting rod is connected to the bottom of the cross pipe, the two ends of the cross pipe are slidably connected and communicated with one end of the T-tube, the two ends of the cross pipe are respectively slidably connected and communicated with a two-section sliding rod, the other two ends of the cross pipe are respectively slidably connected and communicated with a two-section sliding rod, a driving cylinder is arranged on the surface of the base, and the driving cylinder is connected with the middle position of the cross pipe through a pipeline.

[0008] Preferably, a one-way valve is symmetrically arranged on the cross pipe away from the two-stage sliding rod, and a three-way ball valve is arranged on the T-shaped pipe away from the two-stage sliding rod.

[0009] Preferably, the three-way ball valve comprises a rotating block, the rotating block passes through the fixed block and is connected to the semicircular ball valve, and the surface of the semicircular ball valve is slidably connected to the inner wall of the bend of the T-tube.

[0010] Preferably, the rotating block has a through hole, the upper end of the through hole is threadedly connected to the limiting bolt, the lower end of the through hole is slidably connected to the clamping rod, the lower end of the clamping rod is clamped with four clamping holes opened in a ring shape on the surface of the fixed block, and a first elastic member is arranged between the limiting bolt and the clamping rod.

[0011] Preferably, the lifting rod includes a handle, the inner ring of the handle is connected to the outer ring of the nut sleeve, the inner ring of the nut sleeve is threadedly connected to the lifting screw, the lifting screw has a hexagonal hole, the hexagonal hole is slidingly connected to the hexagonal rod, the bottom of the hexagonal rod is connected to the base, and the top of the lifting screw is connected to the bottom of the cross tube.

[0012] Preferably, the bottom of the nut sleeve is connected to the top of the sleeve, the bottom of the sleeve is connected to the bottom plate, the outer ring of the bottom plate is rotatably engaged with the limit block, and the limit block is connected to the base.

[0013] Preferably, the base has a cavity, the top of the cavity is connected to the top plate, the bottom of the cavity is connected to four telescopic rods arranged equidistantly in a ring shape, the output end of the telescopic rod passes through the base and is connected to the support block, the telescopic rod is connected to the control device through a pipeline, and the control device is connected to the driving cylinder through a pipeline.

[0014] Preferably, the control device includes a first piston, the upper end of the first piston is slidably connected to a hole opened in the top plate, the bottom of the first piston is connected to one end of a connecting rod arranged equidistantly in a ring shape, the other end of the connecting rod is connected to a second piston, a second elastic member arranged vertically is arranged at the bottom of the second piston, the outer ring of the second piston and the first piston is in sliding contact with the inner wall of the exhaust pipe, and the bottom of the exhaust pipe is connected to the bottom of the cavity.

[0015] Compared with the prior art, the technical solution of the present invention has the following advantages: (1) By driving the air cylinder to let air enter the pipeline, cross pipe, T-tube, and double-section slide bar, the cables can be extended and retracted according to the site. After the cables are placed, the air cylinder is driven to exhaust air to extract the air in the pipeline, cross pipe, T-tube, and double-section slide bar, so that the cables can be automatically gathered in a unified manner, so that they do not occupy the site for placement, saving space and tightening the cables so that they are not easy to fall off, which is convenient for transportation to the designated area for storage. At the same time, the base is arranged in a ring shape with multiple universal wheels to facilitate transportation.

[0016] (2) Through the one-way valve and the three-way ball valve, each two-stage slide bar can be controlled to inlet and retract. Each two-stage slide bar can hold different types of cables. The one-way valve and the three-way ball valve can be opened at the position where the two-stage slide bar is needed to hold the cable of that type. At the same time, the one-way valve and the three-way ball valve can be opened. At the same time, the cables of that type can be retracted and compressed to prevent them from falling off without affecting the cables on other two-stage slide bars. At the same time, the four clamping holes of the fixed block in the three-way ball valve correspond to closing the ventilation, opening the ventilation and connecting with the two two-stage slide bars, and ventilating with one of the two-stage slide bars. When the rotating block rotates, the clamping rod and the clamping hole will make it easier for the staff to know whether to ventilate the two-stage slide bar and close the ventilation of the two-stage slide bar.

[0017] (3) When part of the double-stage slide bar is opened or the double-stage slide bar is fully opened for use, the uneven placement of the cables may cause uneven weight. At this time, the base with a smaller contact with the ground may be unstable due to the large top area and uneven weight. At this time, the staff steps on the first piston, and the first piston drives the connecting rod and the second piston to move downward, and the second elastic member contracts. The exhaust pipe at the connecting rod position connects the telescopic rod with the driving cylinder, and then the driving cylinder is inhaled, so that the telescopic rod can be extended and extended to drive the support block to extend and support the ground, thereby increasing the force-bearing area and improving the overall stability of the equipment. Then the staff releases the stepped first piston, and the second elastic member pops out, causing the first piston, the connecting rod, and the second piston. The second piston again prevents the gas from entering the telescopic rod, so that the gas entering is restricted in the telescopic rod, and the telescopic rod is limited. At the same time, it makes it more convenient and quick for the staff to extend the telescopic rod, and it can also play a limiting role, thereby improving the convenience of using the equipment.
