Detailed implementation mode

[0038] The following further describes the present utility model with reference to the accompanying drawings.

[0039] This embodiment discloses a cable fixing device 1000. Referring to Figure 1 and Figure 2 , the cable fixing device 1000 is used for fixing the cable 2000 between the cable junction box and the electrical equipment. Among them, a cable trough 3000 is arranged between the cable junction box and the electrical equipment, and the cable fixing device 1000 is arranged in the cable trough 3000.

[0040] Among them, a drain pipe 3100 is arranged at the bottom of the cable trough 3000 to drain the water in the cable trough 3000 and avoid water accumulation on rainy days.

[0041] Referring to Figure 1 and Figure 2 , the cable fixing device 1000 includes a frame assembly 100 and a cable drum assembly 200. The frame assembly 100 is fixedly fitted in the cable trough 3000, and an installation space 110 is formed inside the frame assembly 100, and the cable fixing device 1000 is arranged in the installation space 110.

[0042] Referring to Figure 3 , in this embodiment, the frame assembly 100 includes four side plates 120. The four side plates 120 are connected and enclosed to form a rectangular parallelepiped frame with a hollow interior, and the inner cavity of the rectangular parallelepiped frame forms the installation space 110. The upper ends of the side plates 120 are fixedly connected with angle steel 130 for wrapping edges. The other side of the angle steel 130 for wrapping edges is parallel and attached to the upper side edge of the cable trough 3000, so that the frame assembly 100 is stably fitted in the cable trough 3000.

[0043] In this embodiment, a plurality of steel bar hooks 140 are arranged on the side plates 120. When the cable trough 3000 is cast and formed, the steel bar hooks 140 are covered by the concrete around the cable trough 3000, so that the connection between the frame assembly 100 and the cable trough 3000 is firm and reliable. In addition, in other embodiments, the frame assembly 100 can also be fixedly connected to the inside of the cable trough 3000 through fixing parts such as bolts.

[0044] Referring to Figure 2 and Figure 3, guiding arc slopes 150 are provided at both ends within the installation space 110. The guiding arc slopes 150 are arc surfaces, and their upper ends are connected to the edge of the notch of the cable trough 3000 and are tangent to the notch of the cable trough 3000. The cable 2000 enters the cable trough 3000 through the guiding arc slope 150, then winds around the cable fixing device 1000, and then guides and leaves the cable trough 3000 through another guiding arc slope 150. The cable 2000 is guided by the guiding arc slope 150 to avoid stress concentration when the cable 2000 contacts the edge of the cable trough 3000 and damaging the cable 2000.

[0045] Refer to Figures 3 to 5 , the cable drum assembly 200 includes a drum body 210, a rocker arm 220, and a locking member 230. The drum body 210 is used for the cable 2000 to wind around. The rocker arm 220 is fixedly connected to the drum body 210. The part of the rocker arm 220 located outside the drum body 210 is rotatably connected to the frame assembly 100. The locking member 230 is arranged on the drum body 210, and the frame assembly 100 is provided with a locking structure 160. The drum body 210 is adapted to be placed into the installation space 110, and the locking member 230 can cooperate with the locking structure 160 to lock the drum body 210 in the installation space 110.

[0046] When using this cable fixing device 1000, first release the cooperation between the locking member 230 and the locking structure 160, and rotate the drum body 210 together with the rocker arm 220 upward relative to the frame assembly 100, so as to take it out from the installation space 110, which is convenient for the user to wind the cable 2000 around the drum body 210 or change the number of turns of the cable 2000 wound around the drum body 210. After the cable 2000 on the drum body 210 is wound well, rotate the drum body 210 together with the rocker arm 220 downward relative to the frame assembly 100, so that the drum body 210 is placed into the installation space 110, realizing that the drum body 210 is installed in the installation groove. At this time, the drum body 210 is locked by the cooperation between the locking member 230 and the locking structure 160 of the frame assembly 100, so that the drum body 210 is not easily separated from the cable trough 3000 under normal conditions. This cable fixing device 1000 can conveniently take out the drum body 210 from the cable trough 3000 and fix the drum body 210 in the cable trough 3000, which is convenient for the user to wind the cable 2000 around the drum body 210 or remove the cable 2000 on the drum body 210.

[0047] In this embodiment, the cable trough 3000 is a rectangular trough. Correspondingly, the outer shape of the frame assembly 100 is in the shape of a cuboid, and the installation space 110 is a cuboid cavity. The axis of the drum body 210 is arranged parallel to the short side of the frame assembly 100, so that two or more drum bodies 210 can be placed in the installation space 110.

[0048] In this embodiment, the cylinder 210 is a hollow metal cylinder to reduce the weight of the cylinder 210 and facilitate the movement of the cylinder 210 for winding the cable 2000. In addition, in other embodiments, the cylinder 210 can also be made of other materials, and the cylinder 210 can also be set as a solid cylinder.

[0049] Reference Figure 3 and Figure 6 , wherein a cable pressing block 240 is disposed on the cylinder 210, and the cable pressing block 240 is detachably connected to the cylinder 210. The cable pressing block 240 is plate-shaped, and a groove 241 matching with the cable 2000 is disposed on the side of the cable pressing block 240 facing the cylinder 210. In this embodiment, two cables 2000 are specifically taken as an example, and correspondingly, two grooves 241 are disposed on the cable pressing block 240, and the cable pressing block 240 is pressed outside the two cables 2000, and the two cables 2000 are matched with the two grooves 241.

[0050] In this embodiment, the cable pressing block 240 is specifically fixedly connected to the cylinder 210 by a bolt to facilitate the connection and removal of the cable pressing block 240 and the cylinder 210. In addition, in other embodiments, the cable pressing block 240 can also be connected to the cylinder 210 in other suitable ways.

[0051] Reference Figure 3 , Figure 4 and Figure 7 In this embodiment, the locking member 230 includes a locking pin 231, which is slidably disposed at the end of the cylinder 210. The locking structure 160 includes a locking hole disposed on the inner wall of the installation space 110. When the cylinder 210 is placed in the installation space 110, the locking pin 231 is aligned with the locking hole and can be inserted into the locking hole. The cylinder 210 cooperates with the locking hole of the frame assembly 100 through the locking pin 231, so that the cylinder 210 is locked.

[0052] Among them, a locking sleeve 232 is fixedly arranged on the cylinder 210, and the locking sleeve 232 is arranged toward the locking hole, and one end of the locking sleeve 232 is open toward the locking hole. A sliding groove 233 extending along the axial direction is provided on the peripheral side of the locking sleeve 232, and the sliding groove 233 is connected to the inner cavity of the locking sleeve 232. The locking pin 231 is slidably penetrated in the locking sleeve 232, and a toggle member 234 is arranged on the peripheral side of the locking pin 231, and the toggle member 234 passes through the sliding groove 233 and is exposed outside the locking sleeve 232. By pulling the toggle member 234 to slide along the sliding groove 233, the locking pin 231 can be driven to slide along the axial direction to be inserted into the locking hole or detached from the locking hole, so that the user can lock and unlock the cylinder 210 conveniently.

[0053] In this embodiment, the toggle member 234 is specifically a round rod fixedly connected to the circumference of the locking pin 231 .

[0054] Reference Figure 8 In this embodiment, a first retaining groove 235 and a second retaining groove 236 are further formed on the circumferential side of the locking sleeve 232. Both the first retaining groove 235 and the second retaining groove 236 communicate with the inner cavity of the locking sleeve 232. The first retaining groove 235 is disposed at the end of the sliding groove 233 away from the locking hole, and the second retaining groove 236 is disposed at the end of the sliding groove 233 near the fixed end of the locking hole. Both the first retaining groove 235 and the second retaining groove 236 are vertically communicated with the sliding groove 233.

[0055] When unlocking the cylinder body 210, the toggling member 234 is pulled in a direction away from the locking hole, so that the toggling member 234 abuts against the end of the sliding groove 233 away from the locking hole, and the locking pin 231 disengages from the locking hole. At this time, the toggling member 234 is rotated circumferentially along the locking sleeve 232, so that the toggling member 234 slides into the first retaining groove 235. Thus, the first retaining groove 235 limits the toggling member 234, so that the locking pin 231 cannot move axially along the locking sleeve 232 to slide and insert into the locking hole, which is convenient for maintaining the unlocked state of the cylinder body 210. When the cylinder body 210 is locked, the toggling member 234 is pulled in a direction close to the locking hole, so that the toggling member 234 abuts against the end of the sliding groove 233 close to the locking hole, and the locking pin 231 is inserted into the locking hole. At this time, the toggling member 234 is rotated circumferentially along the locking sleeve 232, so that the toggling member 234 slides into the second retaining groove 236. Thus, the second retaining groove 236 limits the toggling member 234, so that the locking pin 231 is not easily disengaged from the locking hole, which is convenient for maintaining the locked state of the cylinder body 210.

[0056] Reference Figure 7 and Figure 8 A locking compression spring 237 is disposed inside the locking sleeve 232. The locking compression spring 237 abuts between the locking pin 231 and the bottom wall of the locking sleeve 232. The locking compression spring 237 provides a force for the locking pin 231 towards the locking hole. After the cylinder body 210 is placed in the installation space 110, the elastic force of the locking compression spring 237 drives the locking pin 231 to insert into the locking hole to lock the cylinder body 210. At the same time, when the cylinder body 210 is locked, it is not easily disengaged from the installation space 110, and the cable fixing device 1000 is more stable and reliable during use.

[0057] In addition, in other embodiments, the locking member 230 and the locking structure 160 may also be other suitable structures. For example, in one embodiment, the locking member 230 is a bolt disposed on the cylinder body 210, and a through hole for the bolt to pass through is provided on the cylinder body 210. The locking structure 160 is a threaded hole disposed on the side wall of the installation space 110, and the bolt cooperates with the threaded hole after passing through the through hole of the cylinder body 210.

[0058] Reference Figure 4 and Figure 5In this embodiment, a receiving notch 211 is provided on the outer circumference of one end of the cylinder 210 near the locking hole, and the locking member 230 is disposed in the receiving notch 211 to prevent the locking member 230 from protruding out of the cylinder 210, so that the locking member 230 and the cylinder 210 have better integrity and a more reasonable structure. In addition, in other embodiments, the locking member 230 can also be directly disposed on the circumference or end of the cylinder 210.

[0059] Reference Figure 3 and Figure 4 A handle 212 is fixedly disposed on the cylinder 210, and the handle 212 is disposed above the cylinder 210 so that the user can pull the cylinder 210 by hand. In this embodiment, the handle 212 is a U-shaped metal component, which is welded to the cylinder 210. In other embodiments, the handle 212 may also be in other shapes, such as a groove opened on the cylinder 210 for the hand to extend into and apply force.

[0060] A chain 170 is connected to the frame assembly 100, and a hook 171 is connected to one end of the chain 170 away from the frame assembly 100. A pull ear 213 is welded to the cylinder 210, and the hook 171 is connected to the pull ear 213. When the cylinder 210 is placed in the installation space 110, the chain 170 is in a straight state. The cylinder 210 is pulled by the chain 170 to prevent the cylinder 210 from falling rapidly and damaging the cylinder 210, the bottom wall of the cable trough 3000 or the cable 2000 when the cylinder 210 is rotated downward to be placed in the installation space 110 due to the user not holding the cylinder 210 firmly.

[0061] Reference Figure 3 The rocker arm 220 is a long strip frame member, and a plurality of hollow spaces are formed thereon to reduce the weight of the rocker arm 220. One end of the rocker arm 220 is welded and fixedly connected to the cylinder 210, and the other end extends along the length direction of the frame assembly 100.

[0062] Reference Figure 3 and Figure 9 In this embodiment, a rotation hole 221 is provided on the rocker arm 220, and the position of the rotation hole 221 is staggered with the cylinder 210, that is, along the axial direction of the cylinder 210, the projection of the cylinder 210 does not overlap with the projection of the rotation hole 221. A rotating shaft 180 is vertically fixedly provided on the side plate 120 of the frame assembly 100, and the rotating shaft 180 is rotatably matched with the rotating hole 221, so that the rocker arm 220 and the cylinder 210 can rotate around the rotating shaft 180, and then the cylinder 210 can rotate upward to leave the installation space 110 or rotate downward to be placed in the installation space 110.

[0063] In addition, in other embodiments, other suitable ways may also be adopted to achieve the rotational connection between the rocker arm 220 and the frame assembly 100. For example, in one embodiment, the rotation hole 221 may be provided on the side plate 120 of the frame assembly 100, and the rotating shaft 180 is fixedly provided on the rocker arm 220. In one embodiment, the rocker arm 220 and the frame assembly 100 may also be hinged.

[0064] Referring Figure 9 to Figure 10 and

[0065] an elastic member 250 is connected between the rocker arm 220 and the frame assembly 100. The elastic member 250 provides a force acting away from the bottom wall of the cable trough 3000 for the connection point between the rocker arm 220 and the cylinder body 210. Thus, when it is necessary to take out the cylinder body 210 from the cable trough 3000, after the user unlocks the cylinder body 210, the elastic member 250 can play a boosting role to assist the user to drive the cylinder body 210 to rotate in a direction away from the bottom wall of the cable trough 3000 (i.e., upward), facilitating the user to rotate and pull out the cylinder body 210 from the cable trough 3000.

[0066] Specifically, in this embodiment, two cable drum assemblies 200 are provided, and the two cable drum assemblies 200 are mirror - image arranged on the frame assembly 100. After the cable 2000 led out from the cable junction box enters the cable trough 3000, it first winds around the cylinder body 210 of one of the cable drum assemblies 200 for several turns, then winds around the cylinder body 210 of the other cable drum assembly 200 for several turns, and finally extends out from the other end of the cable trough 3000 to the electrical equipment.

[0067] In the two cable drum assemblies 200, the two cylinder bodies 210 are respectively rotatably connected to the frame assembly 100 through the rocker arms 220. When the two cylinder bodies 210 rotate away from the installation space 110, one cylinder body 210 rotates clockwise and the other cylinder body 210 rotates counter - clockwise, and the distance between the two cylinder bodies 210 increases, so as to wind or remove the cable 2000 on the two cylinder bodies 210 respectively.

[0068] In addition, in other embodiments, the cable drum assembly 200 may also be set to one or other suitable values.

[0069] The above description is only the preferred embodiment of the present invention. Therefore, all equivalent changes or modifications made according to the structure, features and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
