Description

Technical Field

[0001] The present invention relates to the technical field of distribution boxes, and particularly to a cable distribution box with a wire winding function. Background Art

[0002] A wire winding function electric box is a device used in the power system, mainly for managing, winding and unwinding cables and wires, and is commonly used in industries, power, construction and other fields. This electric box integrates the functions of winding and managing cables, and can conveniently wind and unwind the cables to ensure the normal operation of the equipment.

[0003] After retrieval, in the prior art, for a distribution box with a winding mechanism, most of them are equipped with a winding roller with a winding function inside the electric box and a motor capable of automatic winding to achieve automatic winding; however, this winding method has many disadvantages. The longer the winding length, the larger the diameter of the required winding roller, which will occupy a large amount of space. Secondly, the winding of the roller will cause the cable itself to generate torsional stress, and it will be in the state of a twisted rope after being withdrawn, and even affect the shape of the internal core wire; therefore, we propose a new wire winding device that can reduce the volume of accessories and prevent torsional stress in the cable body. Summary of the Invention

[0004] Aiming at the technical problem that the winding device in the prior art will cause torsional stress in the cable and then affect the later use, the present invention adopts the following technical solutions:

[0005] A cable distribution box with a wire winding function includes a box door and a cable body. Inside the box door, three groups of winding mechanisms are arranged from top to bottom. Each group of winding mechanisms includes a fixed winding column and a movable column of the same height; a positioning mechanism is arranged on the lower surface of the movable column, and the cable body is coiled around the outer walls of the movable column and the fixed winding column in the same group of winding mechanisms in a lying "8" shape; by setting the movable column and the fixed winding column, and cooperating with this coiling method in the shape of a lying "8", not only can the appropriate number of groups of winding mechanisms and the height of the fixed winding column be selected according to the length of the cable body to save space, but also the phenomenon of torsional stress generated in the cable body after winding is effectively prevented, greatly protecting the core wire and the outer skin inside the cable body, and reducing the reduction of the cable body life caused by winding and unwinding.

[0006] The further setting of the present invention is that wiring plugs and socket bodies are respectively fixed at both ends of the cable body, and two mutually parallel elastic clamping plates with upward openings are fixed near the bottom inside the box door for fixing the socket body on the inner side of the box door.

[0007] A further arrangement of the present invention is that a wire clamping device for fixing the cable body is fixed near the top of the inner wall of the box door. The wire clamping device can ensure that the whole cable body will not fall off, and its joint end, i.e., the end connected to the power output of the electrical box, will not fall off.

[0008] A further arrangement of the present invention is that an installation hole is opened in the middle of the box door, which is located in the middle of the middle set of winding mechanisms. A fixing frame extending to the outside of the box door is fixed in the installation hole, and a heat dissipation fan is fixed in the fixing frame. Two symmetrically arranged guide wind plates with an L-shaped cross-section are fixed near the middle of the inner side of the box door. The two guide wind plates respectively guide the wind to the upper and lower winding mechanisms, so as to accelerate the heat dissipation of the wound cable body under high temperature conditions. This winding method makes the distance between the cable bodies larger, so this heat dissipation method is better than the method of winding one by one.

[0009] A further arrangement of the present invention is that a through groove is opened in the middle of the bottom end of the movable column. Anti-slip chutes I parallel to each other are respectively opened at both ends near the bottom of the through groove. An anti-slip rail slidingly connected with the anti-slip chute I is fixed on the inner wall of the box door. A spring baffle is fixed near the middle of the surface of the box door, and a pressing spring is fixed between the side surface of the spring baffle and the movable column. Cooperating with the positioning mechanism at the bottom end of the movable column, the wound cable body can be tightened after the initial winding is completed, preventing the cable body from falling off.

[0010] A further arrangement of the present invention is that a rectangular notch is opened at the bottom of the through groove between the two anti-slip rails. A jack is opened in the middle of the rectangular notch. A stop push rod is fixed at the bottom end of the rectangular notch, and a right-angle rack extending below the stop push rod is fixed on the side of the spring baffle close to the movable column. The stop push rod is made of a ductile material. By such an arrangement, the position of the movable column can be locked after the cable body is straightened, avoiding the state of always pulling the cable body, so as not to damage its core wire on the premise of ensuring that the cable body is straightened.

[0011] A further arrangement of the present invention is that fixing convex columns and buckles are respectively reserved on the upper surfaces of both ends of the stop push rod. The fixing convex columns are inserted and fixed in the jacks. The buckles are convenient for releasing the positioning of the movable column.

[0012] A further configuration of the present invention is that the cross-sections of the fixed winding column and the movable column are both in the form of a straight slot hole structure, and the fixed winding column and the movable column have the same structure at one end away from the box door, and the top of the fixed winding column is close to the edges of the long sides on both sides and is respectively provided with two mutually parallel anti-slip slide grooves, and the two anti-slip slide grooves are parallel to the long side edges, and the two anti-slip slide grooves are provided with fixed slots at the bottom of the ends away from the two anti-slip slide grooves, and limited blocks are fixed in the fixed slots; the fixed winding column and the movable column are both provided with an anti-slip mechanism on one side of the anti-slip slide groove; and the anti-slip mechanism includes two central The J-shaped baffle strips are symmetrically and slidably connected in the two anti-slip grooves; tooth surfaces are reserved on the opposite sides of the two J-shaped baffle strips; and a rotating shaft hole is opened in the middle of the top of the fixed winding column, and an anti-slip hexagonal combination shaft is rotatably connected in the rotating shaft hole, and a rubbing gear is fixed on the circumference of the anti-slip hexagonal combination shaft, and the rubbing gear is meshed with two tooth surfaces at the same time, and the bottom ends of the two J-shaped baffle strips are fixed with anti-slip sliders that form a sliding fit with the anti-slip grooves; then the two J-shaped baffle strips can be pushed out to both ends by rotating the rubbing gear to prevent the cable body from falling off.

[0013] The present invention is further configured in that eight positioning holes distributed symmetrically in the center are opened at the top of the fixed winding column near the periphery of the rotating shaft hole, and two sliding holes are opened above two of the positioning holes symmetrically located in the center of the rubbing gear, the top part of the anti-slip hexagonal combination shaft is a hexagonal column, and a spring recessed groove is opened in the middle of the top of the hexagonal column, a reset spring is fixed to the bottom of the spring recessed groove, and a screw cap is fixed to the top of the reset spring, a hexagonal hole is opened on the lower surface of the screw cap for sliding cooperation with the hexagonal column, two symmetrical lugs are fixed on the circumferential outer wall of the screw cap near the bottom, and a positioning rod matched with the position and aperture of the sliding hole is arranged on the lower surface of the lug; a protruding ring is fixed to the bottom end of the anti-slip hexagonal combination shaft; when adjusting the protruding length of the two J-shaped baffle strips, it is only necessary to pull the screw cap outwards first to disengage the two positioning rods from the positioning holes, and then rotate the screw cap to drive the rubbing gear to rotate.

[0014] A further configuration of the present invention is that the ends of the straight rod portions of the J-shaped baffle strip are each provided with a through hole parallel to the straight rod portion, and the hook-shaped end of another J-shaped baffle strip is provided with a guide rod that forms a sliding fit with the through hole; by such a configuration, the anti-slip effect of the J-shaped baffle strip can be increased.

[0017] 2. By setting the pressing spring and cooperating with the positioning mechanism at the bottom of the movable column, the coiled cable body can be tightened after the initial coiling is completed, preventing the cable body from falling off.

[0018] 3. By setting the anti-offline mechanism, when adjusting the protruding lengths of the two J-shaped baffle strips, only need to first pull and twist the screw cap outwards to make the two positioning rods disengage from the positioning holes, and then rotate the screw cap to drive the rubbing gear to rotate.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0030] In this embodiment, referring to Figures 1-9 , a cable distribution box with a wire - winding function includes a cabinet door 1 and a cable body 12. Three sets of winding mechanisms are arranged on the inner side of the cabinet door 1 from top to bottom, and each set of winding mechanisms includes a fixed winding post 9 and a movable post 14 of the same height; a positioning mechanism is arranged on the lower surface of the movable post 14, and the cable body 12 is wound around the outer walls of the movable post 14 and the fixed winding post 9 in the same set of winding mechanisms in a lying - "8" - shaped structure; by setting the movable post 14 and the fixed winding post 9 and cooperating with this lying - "8" - shaped winding method, not only can the appropriate number of sets of winding mechanisms and the height of the fixed winding post 9 be selected according to the length of the cable body 12 to save space, but also the phenomenon that the cable body 12 generates torsional stress after winding is effectively prevented, greatly protecting the core wire and the outer skin inside the cable body 12 and reducing the reduction of the service life of the cable body 12 caused by winding and unwinding.

[0037] Referring to Figures 5-6 , Figure 8 , Figure 9, the cross-sections of the fixed winding post 9 and the movable post 14 are both straight groove hole-shaped structures, and the structures of the ends of the fixed winding post 9 and the movable post 14 away from the box door 1 are the same. On the top of the fixed winding post 9, anti-slip chutes two 18 that are parallel to each other are respectively opened near the edges of the two long sides, and the anti-slip chutes two 18 are parallel to the long side edges. At the bottom of the two ends of the two anti-slip chutes two 18 that are away from each other, fixed slots 22 are opened, and limit blocks 21 are fixed in the fixed slots 22; on one side of the fixed winding post 9 and the movable post 14 where the anti-slip chutes two 18 are located, anti-wire-off mechanisms 15 are provided; and the anti-wire-off mechanism 15 includes two J-shaped baffle strips 151 that are symmetrically centered and slidably connected in the two anti-slip chutes two 18 respectively; on the opposite sides of the two J-shaped baffle strips 151, tooth surfaces are reserved; and in the middle of the top of the fixed winding post 9, a rotating shaft hole 19 is opened, and an anti-slip hexagonal combination shaft 156 is rotatably connected in the rotating shaft hole 19, and a rubbing gear 154 is sleeved and fixed around the anti-slip hexagonal combination shaft 156, and the rubbing gear 154 is simultaneously engaged with the two tooth surfaces. At the bottom ends of the two J-shaped baffle strips 151, anti-slip sliders 1511 that form a sliding fit with the anti-slip chutes two 18 are fixed; then, by rotating the rubbing gear 154, the two J-shaped baffle strips 151 can be pushed out towards both ends to prevent the cable body 12 from falling off.

[0038] Refer to Figures 5-6 , Figure 8 , Figure 9 , around the rotating shaft hole 19 on the top of the fixed winding post 9, eight positioning holes 20 that are symmetrically centered are opened, and above two of the positioning holes 20 that are symmetrically centered where the rubbing gear 154 is located, two sliding insertion holes are opened.

[0040] Working principle: When coiling the cable body 12, first move the movable column 14 in each set of winding mechanisms closer to the stationary winding column 9, and then loosen the buckle plate 161 at the top of the anti-retreat ejector rod 16 to fix the movable column 14; then coil the cable body 12 in a lying "8" shape around the outer walls of the movable column 14 and the stationary winding column 9 in the same set of winding mechanisms; finally, after all the winding mechanisms are coiled, lift the buckle plate 161 of the anti-retreat ejector rod 16. Under the action of the pressing spring 2, the movable column 14 moves to the side away from the stationary winding column 9, thereby slowly tightening and straightening the coiled cable body 12; then loosen the buckle plate 161 at the top of the anti-retreat ejector rod 16 to finally fix the movable column 14.
