Description

Technical Field

[0001] The utility model relates to the technical field of cable installation, in particular to an auxiliary device for cable installation. Background Art

[0002] A cable is made of one or more mutually insulated conductors and an outer insulating protective layer, and is a wire for transmitting electric power or information from one place to another. During the installation process of the cable, one end of the cable is often connected to a power distribution cabinet, and the end of the cable is peeled to expose different cable cores; then these different cable cores, such as the neutral wire and the live wire, are respectively connected.

[0003] For example, an auxiliary device for equipment cable installation with the authorization announcement number of CN220022213U can, through the setting of a strong magnet, facilitate the fixation between the upper shell or the lower shell and the equipment under the action of the strong magnet, so as to facilitate the user to support the cable through the upper shell or the lower shell.

[0004] However, there are still some problems when using the above-mentioned auxiliary device for equipment cable installation. For example, the above-mentioned auxiliary device for equipment cable installation uses two upper and lower shells that can be closed to play a clamping and limiting role on the middle cable. However, the thicknesses of cables on the market are different at present, and the diameter of the clamping hole between the upper and lower shells is relatively fixed. Although it can adapt to the clamping of some cables with small thickness deviations, it is difficult to play a good clamping role for some cables with slightly smaller diameters.

[0005] At the same time, for the auxiliary device for equipment cable installation, since the cable may need to be carried on the back of the staff in bundles during installation, and then climb to a high place of the cable line for manual installation and docking, the number of cable lines that the staff can carry at one time is relatively limited. And during operation, one hand also needs to hold the cable line, and then the other hand completes the installation operation. The overall operation is too time-consuming and laborious, and there is also a risk that the cable line will fall to the ground, which is very unfavorable for actual installation operation. Content of the Utility Model

[0006] The utility model aims to solve the above problems existing in the prior art, and provides an auxiliary device for cable installation, which can improve the clamping effect of thin cables and the function and effect of inconvenient operation in actual use.

[0007] The technical solution adopted by the utility model to solve its technical problems is:

[0008] Design an installation auxiliary device for a cable, including a lower shell, an upper shell and a clamping hole. The upper shell is movably connected above the lower shell. A plurality of the clamping holes are fixedly opened between the lower shell and the upper shell. One end of the outer wall of the lower shell is provided with an installation auxiliary device closing structure. The inner wall of the clamping hole is provided with a clamping hole aperture adjustable structure. The lower end of the lower shell is provided with a structure for facilitating carrying and preventing falling off.

[0009] Further improved, the clamping hole aperture adjustable structure includes an inner diameter groove and a hoop. The inner diameter groove is fixedly connected to both sides of the inner wall of the clamping hole. A plurality of transverse grooves are fixedly opened inside the inner diameter groove. A plurality of the transverse grooves are slidably connected with a splicing block inside. The hoop is fixedly connected to the inside of a plurality of the splicing blocks. A plurality of the hoops are slidably connected to the inside of the clamping hole.

[0010] Further improved, the installation auxiliary device closing structure includes a base and a connecting block. The base is fixedly connected to one end of the outer wall of the lower shell. The connecting block is fixedly connected to one end of the outer wall of the upper shell. A plug rod is fixedly connected to the lower end of the connecting block. One side of the inner wall of the base is fixedly connected with a spring. One end of the spring is fixedly connected with a limiting ball. A lifting block is fixedly connected to the top end of the connecting block.

[0011] Further improved, the front end of the outer wall of the limiting ball is clamped with the side wall of the plug rod. The lower end of the plug rod is slidably connected to the inside of the base.

[0012] Further improved, the structure for facilitating carrying and preventing falling off includes a convex block and an anti-slip grip. The convex block is fixedly connected to the bottom end of the outer wall of the lower shell. A movable pin is rotatably connected to the outside of the convex block. A binding rope is fixedly connected to the outside of the movable pin. The anti-slip grip is fixedly installed at the bottom end of the outer wall of the lower shell.

[0013] Further improved, a positioning block is fixedly connected to the other end of the outer wall of the lower shell. A movable block is fixedly connected to the other end of the outer wall of the upper shell. A rotating shaft is rotatably connected to the inside of the positioning block. The other end of the rotating shaft is fixedly connected to the inside of the movable block.

[0014] The beneficial effect of the present utility model is as follows: In the present utility model, the inner diameter groove is designed in an arc shape. When the upper shell and the lower shell are closed to clamp the cable, it can be adjusted according to the thickness of the cable. Specifically, two semi-circular hoops are inserted along the inside of the transverse grooves that are circumferentially drilled in the inner diameter groove. The hoops can be made of rubber material. The hoops are fixed in the inner diameter groove by the transverse splicing blocks through frictional resistance. After the upper shell and the lower shell are closed, the inner diameter of the clamping hole will be reduced by the hoop with a smaller diameter, and a relatively stable clamping effect can also be achieved for some cables with slightly smaller diameters.

[0015] The protrusion is welded and fixed at the lower end of the lower shell, and a freely rotating movable pin is provided on the inner side of the protrusion. The binding rope is made of nylon rope that is not easy to wear hands. One end of the binding rope is fastened to the movable pin, so that when the staff uses the installation auxiliary device to install the cable, they can first wrap the binding rope around the wrist or hang it around the waist. In this way, the cable clamping structure composed of the upper shell and the lower shell can conveniently carry multiple cables at the same time to complete high-altitude operations. During specific operations, the anti-slip handle is made of an aluminum handle with a layer of rubber material on the outside. The anti-slip grip makes it easy for workers to hold the lower shell for auxiliary cable installation operations, and the cable installation auxiliary device is not easy to slip and fall off during specific work.

DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the accompanying drawings:

[0024] Embodiment 1:

[0025] See attached Figure 1 -Attached Figure 6: In this embodiment, an installation auxiliary device for a cable includes a lower shell 1, an upper shell 2, and clamping holes 3. The upper shell 2 is movably connected above the lower shell 1. Both the upper shell 2 and the lower shell 1 are made of high-hardness polystyrene plastic material, having the effects of not being easily conductive and good structural stability. A plurality of clamping holes 3 are fixedly opened between the lower shell 1 and the upper shell 2. A semicircle of the clamping hole 3 is provided inside the upper shell 2, and the other semicircle of the clamping hole 3 is provided inside the lower shell 1. In this way, after the upper shell 2 and the lower shell 1 are closed, a plurality of parallel clamping holes 3 can be formed. The cable to be installed can be inserted into the clamping holes 3 for support and fixation. One end of the outer wall of the lower shell 1 is provided with an installation auxiliary device closing structure 4, the inner wall of the clamping hole 3 is provided with a clamping hole aperture adjustable structure 5, and the lower end of the lower shell 1 is provided with a portable and anti-dropping structure 6.

[0026] The clamping hole aperture adjustable structure 5 includes an inner diameter groove 51 and a hoop 53. The inner diameter groove 51 is fixedly connected to both sides of the inner wall of the clamping hole 3. The inner diameter groove 51 is designed in an arc shape and can be adjusted according to the thickness of the cable when the upper shell 2 and the lower shell 1 are closed to clamp the cable. Specifically, two semicircular hoops 53 are inserted into the inner side of the transverse grooves 52 that are circumferentially drilled along the inner diameter groove 51. The hoop 53 can be made of rubber material. The hoop 53 is fixed in the inner diameter groove 51 by the friction resistance of the transverse splicing blocks 54. In this way, after the upper shell 2 and the lower shell 1 are closed, the inner diameter of the clamping hole 3 will be reduced by the hoop 53 with a smaller diameter, and a more stable clamping effect can also be achieved for some relatively thin cables. A plurality of transverse grooves 52 are fixedly opened inside the inner diameter groove 51. A plurality of splicing blocks 54 are slidably connected to the inner side of the plurality of transverse grooves 52. The hoop 53 is fixedly connected to the inner side of the plurality of splicing blocks 54. The plurality of hoops 53 are slidably connected to the inside of the clamping hole 3.

[0027] The closing structure 4 of the installation auxiliary device includes a base 41 and a connecting block 42. The base 41 is fixedly connected to one end of the outer wall of the lower shell 1, and the connecting block 42 is fixedly connected to one end of the outer wall of the upper shell 2. An empty slot substantially close to the size of the vertically inserted rod 44 is dug inside the base 41. A inserting rod 44 is fixedly connected to the lower end of the connecting block 42. After the upper shell 2 falls and fits with the lower shell 1, the inserting rod 44 below the connecting block 42 at the front end of the upper shell 2 will be inserted into the base 41. A spring 45 is fixedly connected to one side of the inner wall of the base 41. One end of the spring 45 is fixedly connected with a limiting ball 46. The limiting ball 46 is a spherical ball made of iron. The limiting ball 46 is pushed to the inner side of the base 41 by the elastic force applied by the rear spring 45. The end of the falling inserting rod 44 will push the limiting ball 46 to slide into the inner wall of the base 41, and at the same time compress the spring 45 to contract until a circular arc groove reserved on the outer wall of the inserting rod 44 is opposite to the position of the limiting ball 46. In this way, the potential energy accumulated by the spring 45 is released to push the limiting ball 46 into the inserting rod 44 for fixation. At this time, the connecting block 42 locks the upper shell 2 above, and the upper shell 2 cannot be easily opened. When it is necessary to open the connection between the upper shell 2 and the lower shell 1, the staff holds the lifting block 43 above with hand and then pulls it up forcefully. The circular groove on the side wall of the inserting rod 44 and the limiting ball 46 are forcibly pulled out overcoming the frictional force, so that the separation operation can be realized. A lifting block 43 is fixedly connected to the top end of the connecting block 42. The front end of the outer wall of the limiting ball 46 is clamped with the side wall of the inserting rod 44. The lower end of the inserting rod 44 is slidably connected to the inner side of the base 41.

[0028] The anti-dropping structure 6 for easy carrying includes a convex block 61 and an anti-slip grip 64. The convex block 61 is welded and fixed to the lower end of the lower shell 1. There is a movable pin 62 that can rotate freely inside the convex block 61. The convex block 61 is fixedly connected to the bottom end of the outer wall of the lower shell 1. The outside of the convex block 61 is rotatably connected with a movable pin 62. A binding rope 63 is fixedly connected to the outside of the movable pin 62. The binding rope 63 is made of nylon rope that is not easy to abrade the hand. One end of the binding rope 63 is tied to the movable pin 62. In this way, when the staff uses the installation auxiliary device to install the cable, the binding rope 63 can be wound around the wrist or hung on the waist first. In this way, the cable clamping structure composed of the upper shell 2 and the lower shell 1 can facilitate the simultaneous carrying of multiple cables to complete the high-altitude operation. The anti-slip grip 64 is fixedly installed at the bottom end of the outer wall of the lower shell 1. During specific operation, the anti-slip grip 64 can be made by sleeving a layer of rubber material on the aluminum handle. The anti-slip grip 64 is convenient for the worker to hold the lower shell 1 to assist in the cable installation operation. During specific work, the cable installation auxiliary device is not easy to slip and fall.

[0029] On the other end of the outer wall of the lower shell 1, a positioning block 71 is fixedly connected. On the other end of the outer wall of the upper shell 2, a movable block 72 is fixedly connected. Inside the positioning block 71, a rotating shaft 73 is rotatably connected. One end of the upper shell 2 can be flipped on the rotating shaft 73 through the movable block 72. After flipping, the movable block 72 will cause the lower end of the upper shell 2 to close with the top end of the lower shell 1. The other end of the rotating shaft 73 is fixedly connected to the inside of the movable block 72.

[0030] Working principle:

[0031] The cable installation auxiliary device is used by operators during cable installation. The pre-prepared cable is straightened out, and then the staff carries the cable installation auxiliary device to support the cable inside, which facilitates climbing to a high place for cable joint installation.

[0032] Both the upper shell 2 and the lower shell 1 are made of high-hardness polystyrene plastic material, which has the effect of not being easily conductive and good structural stability. A plurality of clamping holes 3 are fixedly opened between the lower shell 1 and the upper shell 2. Inside the upper shell 2, there is a semi-circle of the clamping hole 3, and inside the lower shell 1, there is the other semi-circle of the clamping hole 3. In this way, after the upper shell 2 and the lower shell 1 are closed, a plurality of parallel clamping holes 3 can be formed, and the cables to be installed can be inserted into the clamping holes 3 for support and fixation.

[0033] Inner diameter adjustable structure for clamping the cable of the cable installation auxiliary device:

[0034] The inner diameter groove 51 is designed in an arc shape. When the upper shell 2 and the lower shell 1 are closed to clamp the cable, it can be adjusted according to the thickness of the cable. Specifically, two semi-circular hoop rings 53 are inserted along the inside of the transverse grooves 52 that are circumferentially drilled in the inner diameter groove 51. The hoop rings 53 can be made of rubber material. The hoop rings 53 are fixed in the inner diameter groove 51 by the transverse splicing blocks 54 through frictional resistance. In this way, after the upper shell 2 and the lower shell 1 are closed, the inner diameter of the clamping hole 3 will be reduced by the smaller-diameter hoop rings 53, and it can also achieve a relatively stable clamping effect on some cables with slightly smaller diameters.

[0035] Closing operation of the upper shell and the lower shell of the cable installation auxiliary device:

[0036] A slot is excavated inside the base 41, which is substantially the same size as the vertical insertion rod 44. When the upper shell 2 falls and fits together with the lower shell 1, the insertion rod 44 under the front connection block 42 of the upper shell 2 will be inserted into the base 41. The limiting ball 46 is a round ball made of metal iron. The limiting ball 46 is pushed to the inside of the base 41 by the elastic force applied by the rear spring 45. The end of the falling insertion rod 44 will push the limiting ball 46 to slide into the inner wall of the base 41, and the compression spring 45 will shrink until the insertion rod 44 is inserted into the base 41. A circular arc groove reserved on the outer wall of the rod 44 is opposite to the position of the limiting ball 46, so that the potential energy accumulated by the spring 45 is released to push the limiting ball 46 into the insertion rod 44 for fixing. At this time, the connecting block 42 locks the upper shell 2, and the upper shell 2 cannot be easily opened. When the connection between the upper shell 2 and the lower shell 1 needs to be opened, the staff holds the upper lifting block 43 by hand and then pulls it up with force. The circular groove on the side wall of the insertion rod 44 will overcome the friction with the limiting ball 46 and be forcibly pulled out, so that the separation operation can be achieved;

[0037] The structure of the auxiliary device for installing the cable is easy to take and use:

[0038] The protrusion 61 is welded and fixed at the lower end of the lower shell 1, and a movable pin 62 that can rotate freely is provided on the inner side of the protrusion 61. The binding rope 63 is made of nylon rope that is not easy to wear hands. One end of the binding rope 63 is fastened to the movable pin 62, so that when the staff uses the installation auxiliary device to install the cable, they can first wrap the binding rope 63 around their wrists or hang it around their waists. In this way, the cable clamping structure composed of the upper shell 2 and the lower shell 1 can conveniently carry multiple cables at the same time to complete high-altitude operations. During specific operations, the anti-slip handle 64 can be made of an aluminum handle with a layer of rubber material on the outside. The anti-slip handle 64 is convenient for workers to hold the lower shell 1 for auxiliary cable installation operations, and the cable installation auxiliary device is not easy to slip and fall off during specific work.
