Description

Technical Field

[0001] This application relates to the technical field of heating equipment, and in particular to a cable tray. Background Technology

[0002] There are many types of cable trays, which can be divided into trough-type cable trays, tray-type cable trays, and ladder-type cable trays. They are mainly used for laying cables. Cable trays are divided into trough-type, tray-type, ladder-type, and mesh-type structures, and are composed of supports, brackets, and installation accessories. Cable trays inside buildings can be installed independently or laid on various building (structure) supports and pipe rack supports. They should reflect the characteristics of simple structure, beautiful appearance, flexible configuration, and convenient maintenance. All parts must be galvanized. This applies to cable trays installed outdoors.

[0003] For example, patent application number CN202210029200.4 discloses a cable tray for installation. When the gear column rotates, it can drive two first belt turntables fixedly mounted on the outer surface to rotate together. When the two first belt turntables rotate, they can cooperate with two belts to drive two second belt turntables to rotate. The second belt turntables are respectively fixedly mounted at both ends of a third roller, which can drive the third roller to rotate during use. This provides power when it is necessary to transport cables with bends, which can effectively reduce the labor intensity of manual labor. However, it is inconvenient to fix the cables inside the cable tray, resulting in the cables being crisscrossed and messy, affecting the use. How to make it easier to fix the cables inside the cable tray remains a problem to be solved. Summary of the Invention

[0004] The purpose of this application is to address the problem that it is inconvenient to fix cables inside the cable tray, resulting in a tangled and messy distribution of cables that affects usability. How to make it easier to fix cables inside the cable tray remains an unsolved problem.

[0005] The cable tray provided in this application adopts the following technical solution:

[0006] A cable mounting tray includes a base frame and a crimping assembly;

[0007] The base frame is equipped with a cable limiting component;

[0008] Protective components are connected between the cable limiting components;

[0009] The pressing assembly is installed in the middle of the base frame, and a connecting cover is provided on the upper surface of the pressing assembly;

[0010] The cable limiting assembly includes a limiting frame, a bonding wheel, a soft rubber sleeve, a limiting component, a connecting spring, and a limiting plate. The bonding wheel is rotatably connected inside the limiting frame. The outer surface of the bonding wheel is provided with a soft rubber sleeve, and limiting components are provided on both sides of the bonding wheel. A connecting spring is installed inside the limiting component, and the outer end of the connecting spring is connected to the limiting plate.

[0011] Through the cooperation between the cable limiting assembly and the base frame, the limiting frames in the cable limiting assembly are symmetrically distributed on both sides of the base frame. The contact wheel allows the cable to be smoothly pulled into the limiting frame, and the elastically connected limiting plate clamps and limits the cable, keeping the cable neatly arranged inside the base frame and preventing the cable from twisting or getting tangled. The soft rubber sleeve on the outer surface of the contact wheel can make elastic contact with the cable, reducing wear on the cable.

[0012] Optionally, the protective assembly includes clamping blocks, lifting airbags, fire extinguishing powder, and sealing sheets;

[0013] The clamping block is embedded with a lifting airbag;

[0014] The lifting airbag is filled with fire extinguishing powder.

[0015] The outer surface of the lifting airbag is provided with a sealing piece. The protective component also includes shape memory metal;

[0016] The shape memory metal is disposed on the outer surface of the sealing sheet;

[0017] The shape memory metal is bonded to the sealing sheet.

[0018] With the protective component in place, the clamping block is connected to the middle of the two limiting frames. After the limiting frames limit the cable, the lower surface of the cable comes into contact with the shape memory metal. When the cable short-circuits, the instantaneous current generates a large amount of heat, which causes the shape memory metal to deform. This causes the bottom of the shape memory metal to come into contact with the sealing plate and puncture the sealing plate, thereby allowing the fire extinguishing powder inside the lifting airbag to be sprayed out and act on the outer surface of the cable. This provides emergency treatment for short-circuited cables and prevents fires from occurring.

[0019] Optionally, the pressing assembly includes a protective block, a connecting plate, a soft rubber layer, and a heat insulation pad;

[0020] Both sides of the protective block are connected to connecting plates;

[0021] A soft rubber layer is attached to the lower surface of the connecting plate;

[0022] A heat insulation pad is connected to the bottom of the soft rubber layer. The pressing assembly also includes a rotating shaft, a baffle plate, and comb teeth.

[0023] The rotating shaft is connected to the bottom of the protective block;

[0024] A baffle is provided on the outer surface of the rotating shaft;

[0025] The bottom of the baffle is connected to comb teeth.

[0026] The pressing component is located at the center of the base frame. After the cable routing is completed, the connecting plates on both sides of the protective block are slid out to press and cover the cable. The bottom of the connecting plate is also provided with a soft rubber layer and a heat insulation pad. The heat insulation pad is made of glass wool, which can not only improve the fit with the cable, but also prevent the spread of fire.

[0027] Optionally, a steering assembly is connected to the lower surface of the chassis;

[0028] The steering components are symmetrically distributed about the vertical centerline of the underframe. The steering components include a main rod, a rotating sleeve, a rotating frame, and a rubber sleeve.

[0029] A rotating sleeve is provided on the outer surface of the main rod;

[0030] A rotating frame is connected to the outer surface of the rotating sleeve;

[0031] The surface of the rotating frame is provided with a rubber sleeve.

[0032] Through the cooperative arrangement between the steering assembly and the base frame, the main rod in the steering assembly is installed on both sides of the lower surface of the base frame. The rotating sleeve on the outer surface of the main rod allows the rotating frame to rotate along the rotating sleeve, thereby bending the cable when the cable routing needs to be turned. At the same time, it can also keep the interior of the base frame clean. Furthermore, the contact between the rotating frame and the cable can reduce the possibility of cable damage caused by excessive bending.

[0033] Optionally, a locking assembly is connected to the bottom edge of the connecting cover;

[0034] A filler block is connected to the center of the bottom of the connecting cover. The locking assembly includes a locking rod and a connecting head.

[0035] The bottom of the locking rod is elastically connected to a connecting clip;

[0036] The engaging assembly also includes a limiting rod and a stop block;

[0037] The limiting rod passes through the inside of the locking rod;

[0038] The outer surface of the limiting rod is provided with a stop block.

[0039] Through the cooperative arrangement between the connecting cover and the locking assembly, the locking rod in the locking assembly is symmetrically connected to the surface of the connecting cover. The locking rod is connected to the base frame by the locking head at the bottom of the locking rod. This means that the connection between the base frame and the connecting cover does not require screws, but only pressing, which improves assembly efficiency. The locking rod has a limiting rod and a stop block inside. Rotating the limiting rod will cause the stop block on the outer surface of the limiting rod to press against the two locking heads, thereby strengthening the connection between the base frame and the connecting cover and making it convenient for users.

[0040] In summary, this application includes at least one of the following beneficial technical effects:

[0041] 1. This application uses the mutual cooperation between the cable limiting component and the base frame. The limiting frames in the cable limiting component are symmetrically distributed on both sides of the base frame. The contact wheel allows the cable to be smoothly pulled into the limiting frame, and the elastically connected limiting plate clamps and limits the cable, keeping the cable neatly arranged inside the base frame and preventing the cable from twisting or getting tangled. The soft rubber sleeve on the outer surface of the contact wheel can make elastic contact with the cable, reducing wear on the cable.

[0042] 2. Through the setting of the protective component, the clamp in the protective component is connected to the middle of the two limiting frames. After the limiting frame limits the cable, the lower surface of the cable comes into contact with the shape memory metal. When the cable short-circuits, the instantaneous current will generate a large amount of heat, which will cause the shape memory metal to deform. The bottom of the shape memory metal will come into contact with the sealing plate and puncture the sealing plate, thereby allowing the fire extinguishing powder inside the lifting airbag to be sprayed out and act on the outer surface of the cable. This can provide emergency treatment for the short-circuited cable and prevent the occurrence of fire.

[0043] 3. The pressing component is set in the center of the base frame. After the cable routing is completed, the connecting plates on both sides of the protective block are slid out to press and cover the cable. The bottom of the connecting plate is also provided with a soft rubber layer and a heat insulation pad. The heat insulation pad is made of glass wool, which can not only improve the fit with the cable, but also prevent the spread of fire.

[0044] 4. This application uses the mutual cooperation between the steering assembly and the base frame. The main rod in the steering assembly is installed on both sides of the lower surface of the base frame. The rotating sleeve on the outer surface of the main rod allows the rotating frame to rotate along the rotating sleeve. This allows the cable to be bent when the cable routing needs to be turned, while maintaining the cleanliness of the inside of the base frame. Furthermore, the contact between the rotating frame and the cable can reduce the possibility of cable damage caused by excessive bending.

[0045] 5. This application utilizes the mutual cooperation between the connecting cover and the locking assembly. The locking rod in the locking assembly is symmetrically connected to the surface of the connecting cover. The locking rod is connected to the base frame by the locking head at the bottom of the locking rod. This eliminates the need for screws to fix the connection between the base frame and the connecting cover; only pressing is required, thus improving assembly efficiency. The locking rod has a limiting rod and a stop block rotatably connected inside. Rotating the limiting rod causes the stop block on the outer surface of the limiting rod to press against the two locking heads, thereby strengthening the connection between the base frame and the connecting cover and facilitating user operation.

Detailed Implementation

[0055] Please see Figures 1-8This application provides a technical solution: a cable mounting tray, including a base frame 1 and a pressing assembly 4. A cable limiting assembly 2 is installed inside the base frame 1, and a protective assembly 3 is connected between the cable limiting assemblies 2. The pressing assembly 4 is installed in the middle of the base frame 1, and a connecting cover 5 is provided on the upper surface of the pressing assembly 4. The cable limiting assembly 2 includes a limiting frame 201, a bonding wheel 202, a soft rubber sleeve 203, a limiting member 204, a connecting spring 205, and a limiting plate 206. The bonding wheel 202 is rotatably connected inside the limiting frame 201. A soft rubber sleeve 203 is provided on the outer surface of the bonding wheel 202, and limiting members 204 are provided on both sides of the bonding wheel 202. A connecting spring 205 is installed inside the limiting member 204, and the outer end of the connecting spring 205 is connected to the limiting plate 206.

[0056] Please see Figures 1-3 The cable limiting assembly 2 includes a limiting frame 201, a bonding wheel 202, a soft rubber sleeve 203, a limiting component 204, a connecting spring 205, and a limiting plate 206. The bonding wheel 202 is rotatably connected inside the limiting frame 201. The soft rubber sleeve 203 is provided on the outer surface of the bonding wheel 202. The limiting component 204 is provided on both sides of the bonding wheel 202. The connecting spring 205 is installed inside the limiting component 204, and the limiting plate 206 is connected to the outer end of the connecting spring 205.

[0057] The specific operation is as follows: through the mutual cooperation between the cable limiting component 2 and the base frame 1, the limiting frame 201 in the cable limiting component 2 is symmetrically distributed on both sides of the base frame 1. The cable can be smoothly pulled into the limiting frame 201 by the contact wheel 202, and the cable is clamped and limited by the elastically connected limiting plate 206 to keep the cable neatly arranged inside the base frame 1, so as not to cause the cable to twist and entangle. The soft rubber sleeve 203 on the outer surface of the contact wheel 202 can elastically contact the cable to reduce the wear on the cable.

[0058] Please see Figure 1 and Figure 4 The protective component 3 includes a clamping block 301, a lifting airbag 302, fire extinguishing powder 303, and a sealing plate 304. The lifting airbag 302 is embedded inside the clamping block 301. The lifting airbag 302 is filled with fire extinguishing powder 303. The sealing plate 304 is provided on the outer surface of the lifting airbag 302. The protective component 3 also includes a shape memory metal 305, which is provided on the outer surface of the sealing plate 304. The shape memory metal 305 and the sealing plate 304 are in close contact with each other.

[0059] The specific operation is as follows: through the setting of the protective component 3, the clamp 301 in the protective component 3 is connected to the middle of the two limiting frames 201. After the limiting frame 201 limits the cable, the lower surface of the cable comes into contact with the shape memory metal 305. When the cable is short-circuited, the instantaneous current will generate a large amount of heat, which will cause the shape memory metal 305 to deform, so that the bottom of the shape memory metal 305 comes into contact with the sealing plate 304 and punctures the sealing plate 304, thereby allowing the fire extinguishing powder 303 inside the lifting airbag 302 to be sprayed out and act on the outer surface of the cable, so as to provide emergency treatment for the short-circuited cable and prevent the occurrence of fire.

[0060] Please see Figure 1 , Figure 5 and Figure 6 The pressing assembly 4 includes a protective block 401, a connecting plate 402, a soft rubber layer 403, and a heat insulation pad 404. The protective block 401 is connected to both sides of the connecting plate 402. The soft rubber layer 403 is connected to the lower surface of the connecting plate 402, and the heat insulation pad 404 is connected to the bottom of the soft rubber layer 403. The pressing assembly 4 also includes a rotating shaft 405, a baffle 406, and comb teeth 407. The rotating shaft 405 is connected to the bottom of the protective block 401. The baffle 406 is provided on the outer surface of the rotating shaft 405, and the comb teeth 407 are connected to the bottom of the baffle 406.

[0061] The specific operation is as follows: the pressing component 4 is set at the center of the base frame 1. After the cable routing is completed, the connecting plates 402 on both sides of the protective block 401 are slid out to press and cover the cable. The bottom of the connecting plate 402 is also provided with a soft rubber layer 403 and a heat insulation pad 404. The heat insulation pad 404 is made of glass wool, which can not only improve the fit with the cable, but also prevent the spread of fire.

[0062] Please see Figures 6-7 A steering assembly 6 is connected to the lower surface of the base frame 1, and the steering assembly 6 is symmetrically distributed about the vertical center line of the base frame 1. The steering assembly 6 includes a main rod 601, a rotating sleeve 602, a rotating frame 603 and a rubber sleeve 604. The rotating sleeve 602 is provided on the outer surface of the main rod 601, the rotating frame 603 is connected to the outer surface of the rotating sleeve 602, and the rubber sleeve 604 is provided on the surface of the rotating frame 603.

[0063] The specific operation is as follows: through the mutual cooperation between the steering component 6 and the base frame 1, the main rod 601 in the steering component 6 is installed on both sides of the lower surface of the base frame 1. The rotating sleeve 602 on the outer surface of the main rod 601 allows the rotating frame 603 to rotate along the rotating sleeve 602. Thus, when the cable routing needs to be turned, the cable can be bent. At the same time, it can also keep the interior of the base frame 1 clean. Furthermore, the contact between the rotating frame 603 and the cable can reduce the possibility of cable damage due to excessive bending.

[0064] Please see Figure 1 and Figure 8 A locking component 7 is connected to the bottom edge of the connecting cover 5, and a filling block 8 is connected to the center of the bottom of the connecting cover 5. The locking component 7 includes a locking rod 701 and a connecting head 702. The connecting head 702 is elastically connected to the bottom. The locking component 7 also includes a limiting rod 703 and a stop block 704. The limiting rod 703 passes through the inside of the locking rod 701, and the stop block 704 is provided on the outer surface of the limiting rod 703.

[0065] The specific operation is as follows: through the mutual cooperation between the connecting cover 5 and the locking assembly 7, the locking rod 701 in the locking assembly 7 is symmetrically connected to the surface of the connecting cover 5. The connecting head 702 at the bottom of the locking rod 701 is locked with the base frame 1, so that the connection between the base frame 1 and the connecting cover 5 does not need to be fixed with screws, but only needs to be pressed, which improves the assembly efficiency. The locking rod 701 has a limiting rod 703 and a stop block 704 rotatably connected inside. Rotating the limiting rod 703 will cause the stop block 704 on the outer surface of the limiting rod 703 to abut between the two connecting heads 702, thereby strengthening the connection between the base frame 1 and the connecting cover 5 and making it convenient for users to use.

[0066] In summary, when using the cable tray, the cable is first threaded into the base frame 1. The cable limiting assembly 2, with its symmetrically distributed limiting brackets 201 on both sides of the base frame 1, allows the cable to move smoothly through the limiting brackets 201 via the contact rollers 202. The elastically connected limiting plates 206 clamp and limit the cable, ensuring it remains neatly arranged inside the base frame 1 and preventing twisting or tangling. The soft rubber sleeves 203 on the outer surface of the contact rollers 202 provide elastic contact with the cable, reducing wear. Finally, the pressing assembly 4, located on the base frame... At the center of the protective block 401, after the cable routing and installation are completed, the connecting plates 402 on both sides slide out to press and cover the cable. The bottom of the connecting plate 402 is also provided with a soft rubber layer 403 and a heat insulation pad 404. The heat insulation pad 404 is made of glass wool, which not only improves the fit with the cable but also prevents the spread of fire. Then, pull the connecting plates 402 on both sides of the protective block 401 to press and cover the cable. The bottom of the connecting plate 402 is also provided with a soft rubber layer 403 and a heat insulation pad 404. The heat insulation pad 404 is made of glass wool, which not only improves the fit with the cable but also prevents the spread of fire. And utilize the protective... In the configuration of component 3, the clamping block 301 in the protective component 3 is connected to the middle of the two limiting brackets 201. After the limiting brackets 201 limit the cable, the lower surface of the cable comes into contact with the shape memory metal 305. When a short circuit occurs in the cable, the instantaneous current generates a large amount of heat, which causes the shape memory metal 305 to deform. This causes the bottom of the shape memory metal 305 to come into contact with the sealing plate 304 and puncture the sealing plate 304, thereby allowing the fire extinguishing powder 303 inside the lifting airbag 302 to be sprayed out and act on the outer surface of the cable. This provides emergency treatment for the short-circuited cable, preventing fires. The shield 406 is then rotated and clipped off along the rotating shaft 405, allowing the rotating shaft to... The comb teeth 407 on the lower surface of 405 further comb the cable. Finally, through the mutual cooperation between the connecting cover 5 and the locking assembly 7, the locking rod 701 in the locking assembly 7 is symmetrically connected to the surface of the connecting cover 5. The connecting head 702 at the bottom of the locking rod 701 is locked to the base frame 1, so that the connection between the base frame 1 and the connecting cover 5 does not need to be fixed with screws, but only needs to be pressed, which improves the assembly efficiency. The locking rod 701 has a limiting rod 703 and a stop block 704 rotatably connected inside. Rotating the limiting rod 703 will cause the stop block 704 on the outer surface of the limiting rod 703 to abut between the two connecting heads 702, thereby strengthening the connection between the base frame 1 and the connecting cover 5.
