Description

Technical Field

[0001] The utility model relates to the technical field of electrical engineering, in particular to a cable fixing device used in electrical engineering. Background Art

[0002] Electrical engineering is a general term for engineering fields related to the production, transmission, conversion, control, storage, use and manufacture of electrical equipment of electric energy. In the field of electrical engineering, a large number of cables are needed for the transmission of electric energy or electrical signals. When laying these cables, a large number of fixing devices are needed to fix them.

[0003] Application number 202322007219.1 provides a cable fixing device for electrical engineering, including a fixed shell, a cavity is opened inside the fixed shell, a motor is fixedly connected to the center of the inner wall of the cavity, threaded rods are rotatably connected to the left and right sides of the upper and lower inner walls of the cavity, the lower sides of the two threaded rod walls are meshed with the output end of the motor through a transmission mechanism, an upper fixed plate is fixedly connected to the upper part of the inner wall of the fixed shell, lifting blocks are threadedly connected to the upper sides of the two threaded rod walls, connecting blocks are fixedly connected to the opposite side surfaces of the two lifting blocks, and the lower side surfaces of the two connecting blocks are commonly fixedly connected to the lower fixed plate, and a plurality of first wire hole grooves are opened on the lower surface of the upper fixed plate.

[0004] The device uses the motor to drive the screw to rotate through the transmission device, thereby driving the lifting block to move, and then driving the lower fixing plate to move, so as to achieve automatic clamping and automatic release of the cable, simplifying the process of cable fixing and removal. However, the number of fixing devices required for cable fixing is huge, and the installation and removal intervals are long. The large-scale use of motors will increase the installation cost. Secondly, if the motor is not used for a long time, the insulation performance of the internal winding will be affected by air humidity and dust, and the grease may dry, which may make it impossible to start the machine correctly, resulting in the inability to remove the cable.

At this time, the eccentric wheel rotates inwards and the friction force is low, so the anti-dropping plug plate can be drawn out of the support frame. After the friction force is lost, the spacer block can move freely to achieve quick release. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Embodiment 1:

[0031] See also Figure 1-5 The utility model describes the above technical solution in detail through the following embodiments:

[0032] A cable fixing device for electrical engineering, comprising:

[0033] The fixing frame 1 includes a base 11, which is used to be fixed to a wall or the ground. A support frame 13 is symmetrically welded in the middle of the top surface of the base 11. A crossbeam 16 is fixed on the top of the support frame 13 by screws. A clamping assembly 2 is provided between the support frames 13, and the clamping assembly 2 and the support frame 13 are connected by a fixing assembly 3.

[0034] The edge of the base 11 is provided with a plurality of mounting grooves 12 for bolts to pass through. The base 11 can be fixedly mounted on a wall or the ground or other known cable brackets by bolts.

[0035] The crossbeam 16 fixes the top end of the support frame 13 to prevent the support frame 13 from tilting outward.

[0036] The supporting frame 13 has mounting slots 14 on opposite sides thereof. A fixing plate 15 is welded on the outer side of the top end of the supporting frame 13 . The clamping assembly 2 is located between the two mounting slots 14 , and the fixing assembly 3 is located inside the mounting slots 14 .

[0037] The cross section of the support frame 13 is C-shaped.

[0038] The clamping assembly 2 includes a plurality of spacer blocks 21, and each spacer block 21 has a plurality of upper clamping plates 22 and a plurality of lower clamping plates 23 welded on the top and bottom surfaces respectively. The upper clamping plates 22 and the lower clamping plates 23 of two adjacent spacer blocks 21 can be inserted into each other, and the upper clamping plates 22 and the lower clamping plates 23 are used to clamp cables.

[0039] There are two upper clamping plates 22 on the top surface of each spacer block 21, and three lower clamping plates 23 on the bottom surface of each spacer block 21. The upper clamping plates 22 and the lower clamping plates 23 have the same shape and size.

[0040] The left and right ends of the spacer block 21 , the upper clamping plate 22 and the lower clamping plate 23 are slidably connected to the mounting slide groove 14 .

[0041] The installation slide groove 14 can limit the sliding direction of the spacer block 21, the upper clamping plate 22 and the lower clamping plate 23, and prevent the spacer block 21, the upper clamping plate 22 and the lower clamping plate 23 from moving forward and backward.

[0042] A V-shaped opening 24 is provided on one side of the upper clamping plate 22 and the lower clamping plate 23 away from the spacer block 21. The V-shaped openings 24 of the upper clamping plate 22 and the lower clamping plate 23 correspond to each other. An elastic protective sleeve 25 is provided in the V-shaped opening 24 for wrapping cables.

[0043] The elastic protective sleeve 25 is a rubber sleeve, and a side of the elastic protective sleeve 25 is provided with an opening. The elastic protective sleeve 25 is used to wrap the cable to provide protection for the cable.

[0044] When the upper clamping plate 22 and the lower clamping plate 23 are inserted into each other, the size of the V-shaped opening 24 can be controlled by controlling the insertion depth, so as to adapt to cables of different diameters.

[0045] The fixing assembly 3 includes an eccentric wheel 31 and an anti-slip plate 34. The eccentric wheel 31 is rotatably mounted at both ends of the spacer block 21. The anti-slip plate 34 is slidably mounted on the inner side of the support frame 13 and fixedly connected to the support frame 13 by fixing bolts 37. A friction plate 35 is welded on the anti-slip plate 34 facing the side of the eccentric wheel 31, and the friction plate 35 abuts against the eccentric wheel 31.

[0046] When the eccentric wheel 31 slides upward, the friction force is directed downward, and the eccentric wheel 31 rotates downward and outward, and the distance from the contact part between the eccentric wheel 31 and the friction plate 35 to the rotation axis increases, thereby increasing the friction force between the eccentric wheel 31 and the friction plate 35.

[0047] When the eccentric wheel 31 slides downward, the friction force is directed upward, thereby driving the eccentric wheel 31 to rotate upward and inward, and the distance from the contact point between the eccentric wheel 31 and the friction plate 35 to the rotation axis is reduced, thereby reducing the friction force between the eccentric wheel 31 and the friction plate 35.

[0048] A handle 36 is provided on the outer side of the top of the anti-dropping plug plate 34 , the bottom surface of the handle 36 abuts against the top surface of the fixing plate 15 , and a fixing bolt 37 passes through the handle 36 and the fixing plate 15 to fix the fixing plate 15 .

[0049] The fixing bolt 37 fixes the handle 36 and the fixing plate 15 to prevent the anti-dropping plug plate 34 from sliding upward.

[0050] After loosening the fixing bolt 37 , an upward pulling force is applied to the handle 36 , so that the anti-dropping plug plate 34 and the friction plate 35 can be pulled out from the installation slide groove 14 .

[0051] Mounting frames 32 are provided on both sides of the eccentric wheel 31 , and the eccentric wheel 31 can rotate between the mounting frames 32 . The mounting frames 32 are welded and mounted on both ends of the spacer block 21 , and the mounting frames 32 can slide inside the anti-dropping plug plate 34 .

[0052] The eccentric wheel 31 is rotatably connected to the mounting frame 32 via a rotating shaft. The outer side surface of the mounting frame 32 is flush with the outer side surface of the spacer block 21. A gap is left between the end surface of the mounting frame 32 and the friction plate 35.

[0053] An extrusion spring 33 is provided between the mounting frames 32 , and two ends of the extrusion spring 33 are fixedly connected to the eccentric wheel 31 and the spacer block 21 respectively. The extrusion spring 33 applies a force to the eccentric wheel 31 in the direction of the anti-dropping plug plate 34 .

[0054] The elastic force of the extrusion spring 33 can ensure that the eccentric wheel 31 always keeps in contact with the friction plate 35, so as to prevent the eccentric wheel 31 from rotating due to vibration, thereby losing friction and causing the fixing strength of the clamping assembly 2 to the cable to change.

[0055] In this embodiment, when the operator uses the device, he first fixes the base 11 to the required position by bolts.

[0056] Put the elastic protective sleeve 25 onto the cable.

[0057] The anti-dropping plug plate 34 is inserted into the installation slide groove 14 , and the handle 36 and the fixing plate 15 are fixedly connected by the fixing bolts 37 .

[0058] Align the ends of the spacer block 21 , the upper clamping plate 22 and the lower clamping plate 23 with the installation slots 14 , and insert them horizontally into the two installation slots 14 .

[0059] At this time, the eccentric wheel 31 slides downward following the spacer block 21, and the eccentric wheel 31 contacts the friction plate 35, and is subjected to an upward friction force, so that the eccentric wheel 31 rotates upward and inward, and the friction force between the eccentric wheel 31 and the friction plate 35 is reduced, so that the spacer block 21, the upper clamping plate 22 and the lower clamping plate 23 can slide downward smoothly.

[0060] After the first set of spacer blocks 21, upper clamping plates 22 and lower clamping plates 23 are placed, the portion of the cable covered with the elastic protective cover 25 is placed into the V-shaped opening 24 of the upper clamping plate 22, and then the second set of spacer blocks 21, upper clamping plates 22 and lower clamping plates 23 are placed to clamp the elastic protective cover 25.

[0061] By controlling the insertion depth of the upper clamping plate 22 and the lower clamping plate 23 , the size of the V-shaped opening 24 can be controlled, thereby controlling the clamping force on the elastic protective sleeve 25 .

[0062] After the clamping assembly 2 is placed in place, the eccentric wheel 31 always keeps in contact with the friction plate 35 under the elastic force of the extrusion spring 33. When the spacer block 21 has a tendency to slide upward, the friction force between the eccentric wheel 31 and the friction plate 35 is downward, thereby driving the eccentric wheel 31 to rotate downward and outward, and the distance between the contact part of the eccentric wheel 31 and the friction plate 35 and the rotation axis increases, thereby increasing the friction force between the eccentric wheel 31 and the friction plate 35. In turn, the movement of the spacer block 21 is restricted, and the spacer block 21 is fixed.

[0063] After all cables are fixed, the crossbeam 16 is placed on the top of the support frame 13 and fixed with screws to prevent the support frame 13 from tilting outward.

[0064] When the cable needs to be replaced or removed, first remove the crossbeam 16.

[0065] Then, the fixing bolt 37 is released and an upward pulling force is applied to the handle 36 to drive the anti-dropping plug plate 34 and the friction plate 35 to move upward. At this time, in the direction of the friction force between the friction plate 35 and the eccentric wheel 31, the friction force between the eccentric wheel 31 and the friction plate 35 is reduced, and the anti-dropping plug plate 34 and the friction plate 35 can be smoothly pulled out.

[0066] After the anti-dropping plug plate 34 and the friction plate 35 are pulled out, the friction force on the eccentric wheel 31 disappears, and the clamping assembly 2 can move freely.

[0067] By taking the spacer block 21 , the upper clamping plate 22 and the lower clamping plate 23 out of the installation slide groove 14 , the elastic protective cover 25 can be released, thereby releasing the cable.

[0068] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
