Description

Technical Field

[0001] This utility model relates to the field of building electrical cable positioning technology, and in particular to a building electrical cable positioning device. Background Technology

[0002] The electrical system of an underground parking garage needs to supply power to lighting, ventilation, fire protection and other equipment, which involves laying a large number of cables. In order to ensure that the cables are distributed in an orderly manner, most of them are positioned on cable trays by binding straps. The cable trays are suspended under the beams at the top of the underground parking garage so as not to affect the passage of vehicles and people in the parking garage.

[0003] Most existing cable ties have rough surfaces. If the ties are too tight on the cable, it can cause sharp friction or squeezing between the ties and the cable sheath, which can easily lead to damage to the cable surface. If the ties are too loose on the cable, it can cause the cable to shake and shift within the cable tray, thus affecting the positioning effect of the cable. Utility Model Content

[0004] Therefore, it is necessary to provide a building electrical cable positioning device to address the problems of excessively tight cable ties causing sharp friction or compression between the cable ties and the cable sheath, which can easily lead to damage to the cable surface, and excessively loose cable ties causing the cable to sway and shift within the cable tray.

[0005] The system includes: a cable tray; and a positioning mechanism. The positioning mechanism comprises cable guide plates evenly spaced at the ends of the cable tray, with pressure plates on top of the guide plates. Evenly spaced rubber blocks are fixedly connected to the ends of both the guide plates and the pressure plates. The surfaces of the rubber blocks are curved into an arc shape. Two friction rods are slidably connected to the inner wall of the pressure plates, with their surfaces slidably connected to the inner wall of the guide plates. Through the interaction of the guide plates, pressure plates, and the curved rubber blocks, the cables laid within the cable tray are orderly distributed and positioned, preventing damage to the cable sheath due to excessive tightness in cable positioning. The friction rods ensure that the pressure plates are positioned on top of the guide plates, thereby achieving stable cable positioning and guaranteeing effective cable positioning.

[0006] In one embodiment, a locking rod is slidably connected to the inner wall of the pressure plate, and the locking rod is slidably connected to the inner walls of the fixing plate and the friction rod in sequence.

[0007] In one embodiment, a dust block is fixedly connected to the surface of the clamping rod, and one side of the dust block contacts one side of the pressure plate.

[0008] In one embodiment, a positioning rod is slidably connected to the inner wall of the dust block, and the surface of the positioning rod is slidably connected to the inner wall of the pressure plate and the friction rod in sequence.

[0009] In one embodiment, a spring is fixedly connected to the top of the locking rod, and the top of the spring is fixedly connected to the inner wall of the pressure plate. The spring pushes the locking rod downwards, sliding it into the fixing plate and friction rod. The positioning rod then slides into the pressure plate and friction rod, thereby locking the friction rod and ensuring that the end of the friction rod stably abuts against the end of the fixing plate. This ensures the pressure plate firmly positions the cable on the fixing plate, thus guaranteeing the effective positioning of the cable.

[0010] In one embodiment, the inner wall of the guide plate is provided with equally spaced ventilation holes, and the top of the pressure plate is provided with equally spaced air vents.

[0011] In one embodiment, the inner walls of both the ventilation holes and the vent holes are recessed into a rectangular funnel shape. The interplay between the recessed rectangular funnel-shaped ventilation holes and the vent holes allows for ventilation of the cables within the cable guide plate and pressure plate, preventing heat concentration in the cables within these plates.

[0012] In one embodiment, a limiting block is fixedly connected to the surface of the positioning rod, and the surface of the limiting block is slidably connected to the inner wall of the pressure plate, the friction rod, and the dust block in sequence. The limiting block limits the movement of the positioning rod, preventing it from dislodging from the dust block.

[0013] Beneficial effects

[0014] 1. By cooperating with the cable guide plate, the pressure plate, and the rubber block with a curved surface, the cables laid in the cable tray are distributed and positioned in an orderly manner, avoiding damage to the cable sheath caused by excessive tightness in positioning the cables. The friction rod enables the pressure plate to be positioned on top of the cable guide plate, thereby achieving stable positioning of the cables and ensuring the positioning effect of the cables.

[0015] 2. The spring pushes the lever down and slides into the cable guide plate and friction rod. The positioning rod slides into the pressure plate and friction rod, thus locking the friction rod and ensuring that the end of the friction rod is stably against the end of the cable guide plate. This ensures that the pressure plate is firmly positioned on the cable guide plate, thereby ensuring the positioning effect of the cable. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The following is combined with Figures 1-5 This utility model describes a building electrical cable positioning device.

[0026] In one embodiment, a building electrical cable positioning device includes: a cable tray 100; and a positioning mechanism 200. The positioning mechanism 200 includes cable guide plates 201 evenly distributed at the ends of the cable tray 100. A pressure plate 202 is provided on the top of the cable guide plates 201. Rubber blocks 203 are evenly distributed at the ends of the cable guide plates 201 and the pressure plate 202. The surfaces of the rubber blocks 203 are curved into an arc shape. Two friction rods 204 are slidably connected to the inner wall of the pressure plate 202. The surfaces of the friction rods 204 are slidably connected to the inner wall of the cable guide plates 201.

[0027] It should be noted that both the cable guide plate 201 and the pressure plate 202 are galvanized steel plate components, which have good strength and corrosion resistance. The galvanized steel plate components of the cable guide plate 201 and the pressure plate 202 can withstand a certain weight and external impact, are not easily deformed, and can provide stable support and positioning for the cable.

[0028] In this embodiment, when it is necessary to locate the cables in the underground parking lot of the building, the cable tray 100 is screwed into the bottom and the cable guide plate 201, so that the cable guide plate 201 is fixed in the cable tray 100. The cable tray 100 is hoisted under the top beam in the underground parking lot by the cooperation of bolts, nuts and hangers. The installers lay the cables that supply power to lighting, ventilation, fire protection and other equipment in the cable tray 100 according to the construction process. Multiple cables are placed in sequence on the surface of the rubber block 203 on the top of the cable guide plate 201. After the laying is completed, the pressure plate 202 is pressed down on the surface of the cable, so that the friction rod 204 slides into the cable guide plate 201 and the rubber block 203 at the bottom of the pressure plate 202 abuts against the surface of the cable. The friction rod 204 is rotated so that the end of the friction rod 204 abuts against the inner wall of the cable guide plate 201, so that the pressure plate 202 is positioned on the cable guide plate 201, thereby positioning the cable.

[0029] like Figure 3 and Figure 5 As shown, a locking rod 205 is slidably connected to the inner wall of the wire pressing plate 202. The surfaces of the locking rod 205 are slidably connected to the inner walls of the wire fixing plate 201 and the friction rod 204. A dust blocking block 206 is fixedly connected to the surface of the locking rod 205. One side of the dust blocking block 206 contacts one side of the wire pressing plate 202. A positioning rod 207 is slidably connected to the inner wall of the dust blocking block 206. The surfaces of the positioning rod 207 are slidably connected to the inner walls of the wire pressing plate 202 and the friction rod 204. A spring 208 is fixedly connected to the top of the locking rod 205. The top of the spring 208 is fixedly connected to the inner wall of the wire pressing plate 202. A limiting block 209 is fixedly connected to the surface of the positioning rod 207. The surfaces of the limiting block 209 are slidably connected to the inner walls of the wire pressing plate 202, the friction rod 204, and the dust blocking block 206.

[0030] It should be noted that the rubber block 203, friction rod 204, clamping rod 205, dust block 206, and positioning rod 207 are all silicone rubber components, which have good high temperature resistance, excellent elasticity, and a high coefficient of friction. The rubber block 203, friction rod 204, clamping rod 205, dust block 206, and positioning rod 207 can maintain stable performance under different temperature environments. When the temperature of the underground parking lot changes, the rubber block 203, friction rod 204, clamping rod 205, dust block 206, and positioning rod 207 can still maintain their elasticity and flexibility, so that the friction rod 204 is stably located within the alignment plate 201, the clamping rod 205 is stably located within the alignment plate 201 and the friction rod 204, and the positioning rod 207 is stably located within the alignment plate 201 and the friction rod 204.

[0031] In this embodiment, the limiting position of the locking rod 205 is loosened, and the elastic force of the spring 208 pushes the locking rod 205 down and slides into the fixing plate 201 and the friction rod 204 in sequence, pushing the positioning rod 207, so that the positioning rod 207 slides into the pressing plate 202 and the friction rod 204 in sequence, so that the end of the friction rod 204 is stably abutting against the fixing plate 201.

[0032] like Figure 2 As shown, the inner wall of the guide plate 201 is provided with equally spaced ventilation holes 210, and the top of the pressure plate 202 is provided with equally spaced air holes 211. The inner walls of the ventilation holes 210 and the air holes 211 are recessed in a rectangular funnel shape.

[0033] In this embodiment, the air inside the cable tray 100 flows through the ventilation holes 210 and the air vents 211 to the cable between the cable guide plate 201 and the pressure plate 202, thus preventing the cable between the cable guide plate 201 and the pressure plate 202 from becoming stuffy.

[0034] Working principle: The pressure plate 202 is pressed down on the cable surface, causing the friction rod 204 to slide into the fixing plate 201. The rubber block 203 at the bottom of the pressure plate 202 abuts against the cable surface. The friction rod 204 is rotated, causing its end to abut against the inner wall of the fixing plate 201, loosening the limit on the locking rod 205. The elastic force of the spring 208 pushes the locking rod 205 down, sliding it into the fixing plate 201 and the friction rod 204 in sequence. This pushes the positioning rod 207, causing it to slide into the pressure plate 202 and the friction rod 204 in sequence, so that the end of the friction rod 204 is stably abutting against the fixing plate 201. This positions the pressure plate 202 on the fixing plate 201, thereby positioning the cable.

[0035] It should be noted that the cable tray 100, the wire guide plate 201, the wire clamping plate 202, and the spring 208 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs, and will not be elaborated here.

[0036] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
