[0001] The invention belongs to the technical field of wire fixing, in particular to a binding-free wire fixing device. Background Art

[0002] The tie-free conductor fixing device is a device that can effectively fix the conductor without the need for traditional binding methods (such as cable ties, ropes, etc.). It is often used in electrical installation, wiring engineering and other fields. Its unique design simplifies the conductor fixing process and improves wiring efficiency and aesthetics. The tie-free conductor fixing device is suitable for different types of insulators and conductors and has strong adaptability. Whether it is a column insulator or a cross-arm insulator, it can be fixed with the corresponding tie-free conductor fixing device, which makes the tie-free conductor fixing device have broad application prospects in the power system.

[0003] Traditional wire fixing methods, such as using cable ties, rope binding or screw fastening, have many disadvantages. Taking cable tie binding as an example, in large-scale wiring projects, each wire needs to be manually inserted into the cable tie and tightened and fixed, which is cumbersome and time-consuming. If the wire needs to be adjusted, replaced or repaired later, the cable tie usually needs to be cut and destroyed and cannot be reused, which not only causes material waste, but also requires reinstalling new cable ties, increasing costs and workload. Cable tie and screw fixing devices are usually suitable for wires within a specific diameter range. If the wire diameter varies greatly, it is necessary to prepare fixing materials of various specifications, which increases management costs and installation difficulty. Moreover, it is difficult to accurately adjust the fixing position and spacing of the wire with traditional fixing methods, which may cause the wires to be loosely fixed or squeezed against each other, affecting the electrical performance and service life of the wires. Therefore, a cable tie-free wire fixing device is proposed. Summary of the invention

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figures 1 to 6 As shown, the present invention provides a binding-free wire fixing device, comprising a fixing body 1, on which a fixing mechanism 2 and an adjustment mechanism 3 are respectively installed; The fixing mechanism 2 includes a bolt 21, a pressing block 22, a butterfly washer 23 and a flat washer 24. The bottom end of the bolt 21 is rotatably connected to the pressing block 22 through a bearing, and the butterfly washer 23 and the flat washer 24 are installed between the bolt 21 and the pressing block 22. The adjustment mechanism 3 includes a push rod 31 , an inclined block 32 , a vertical plate 33 and a positioning block 34 . The inclined block 32 overlaps the bottom end of the push rod 31 , one end of the inclined block 32 overlaps the top end of the vertical plate 33 , and the positioning block 34 is fixedly connected to the bottom surface of the vertical plate 33 .

[0020] The above scheme is adopted: the fixed body 1 is used as the main frame of the whole device, a placement bin 101 is provided inside for installing the adjustment mechanism 3, a vertical cavity 102 is provided on the top for limiting the bolt 21, and provides an installation and support basis for other components. The material is polyamide PA66, and it is processed by injection molding technology, and has certain strength and durability. By setting the adjustment mechanism 3 and other structures, the torque head 25 on the top of the bolt 21 is turned by hand or tools to make the bolt 21 rotate clockwise, and the bolt 21 moves downward in the vertical cavity 102, driving the pressure block 22 to descend together. As the pressure block 22 gradually approaches the wire 4, pressure is applied to the wire 4 until the wire 4 is firmly fixed between the pressure block 22 and the base 5, and the bolt 21 drives the push rod 31 to move downward, and the push rod 31 pushes the inclined block 32 to move horizontally, and the inclined block 32 squeezes the vertical plate 33 to move downward, and the vertical plate 33 is moved by the sliding block 35. The inner wall of the fixed body 1 slides down smoothly, thereby driving the positioning block 34 to descend, adjusting the distance between the positioning block 34 and the wire 4 to better fix the wire 4. Only by turning the torque head 25 on the top of the bolt 21 by hand or tool, the pressure and fixation of the wire 4 by the pressure block 22 and the adjustment of the distance between the positioning block 34 and the wire 4 can be achieved simultaneously. There is no need to perform multiple cumbersome steps for different fixing requirements as in the traditional fixing method, which greatly improves the efficiency of fixing the wire 4. It is especially suitable for large-scale wiring projects and can save a lot of time and labor costs. The structure of the entire fixing device is based on the linkage design of the bolt 21, and the various components are closely matched and compactly arranged. In a limited space, such as a distribution box, a control cabinet and other narrow spaces, it can efficiently complete the task of fixing the wire 4 without taking up too much space, which is conducive to the reasonable planning and overall layout of the wiring.

[0021] like Figures 1 to 6 As shown, a placement bin 101 is provided inside the fixed body 1, and the placement bin 101 is used to install the adjustment mechanism 3. A vertical cavity 102 is provided on the top of the fixed body 1, and the vertical cavity 102 is used to limit the bolt 21. A torque head 25 is fixedly installed on the top of the bolt 21, and a nut 26 is threadedly connected to the end of the bolt 21 away from the torque head 25, and the nut 26 is installed in the vertical cavity 102. A fixing plate 311 is fixedly connected to the top of the push rod 31. There are two fixing plates 311, and the two fixing plates 311 are connected to the bolt 21 through a bearing. The material of the fixed body 1 and the pressure block 22 is polyamide PA66, which is processed by injection molding technology, and the bottom end of the push rod 31 is inclined.

[0022] By adopting the above scheme: the bolt 21 drives the push rod 31 to move downward, the push rod 31 pushes the inclined block 32 to move horizontally, the inclined block 32 squeezes the vertical plate 33 to move downward, and the spacing between the positioning block 34 and the wire 4 is adjusted. By adjusting the spacing between the positioning block 34 and the wire 4, the pressure applied by the pressure block 22 on the wire 4 can be more evenly distributed, avoiding the situation where the insulation layer of the wire 4 is damaged due to local pressure concentration caused by poor contact between the fixing device and the wire 4 or improper spacing. The bolt 21 rotates through the torque head 25 at the top and cooperates with the nut 26 to realize the lifting and lowering control of the pressure block 22 , thereby fixing the wire 4, and its bottom end is rotatably connected with the pressing block 22 through a bearing, so that the pressing block 22 can maintain relative rotation during the lifting process. The bottom surface of the pressing block 22 is in an arc shape, and the contact area with the wire 4 is large, which can better fix the wire 4. Under the drive of the bolt 21, pressure is applied to the wire 4. The material is polyamide PA66, which is processed by injection molding. The butterfly washer 23 is installed between the bolt 21 and the pressing block 22 to provide elastic buffering to prevent the nut 26 from loosening and enhance the fixing effect. The flat washer 24 disperses the pressure of the nut 26 on the pressing block 22 and protects the surface of the pressing block 22. The pressure distribution is more uniform. The wires 4 in electrical wiring have various specifications and different diameters. The adjustment mechanism allows the fixing device to flexibly adapt to various wires 4. By adjusting the spacing, it is firmly fixed. There is no need to prepare various specifications of fixing devices, saving costs and installation time. Wires 4 of different diameters require different pressures and contact areas to fix them. Adjusting the spacing between the positioning block 34 and the wire 4 can make the pressure block 22 and the positioning block 34 fit the contour of the wire 4, increase the contact area, and evenly disperse the pressure. For example, in an industrial production workshop, there is a lot of vibration. After precise adjustment, the wire 4 is fixed more stably, reducing the vibration-induced The risk of wire 4 loosening and falling off is reduced to ensure production safety and normal operation of equipment. The rotation of bolt 21 drives push rod 31 to move up and down through fixing plate 311. When push rod 31 moves downward, the inclined surface of its bottom end pushes inclined block 32 to move horizontally. The inclined surface of inclined block 32 overlaps with the top of vertical plate 33, thereby squeezing vertical plate 33 to move downward. Vertical plate 33 slides on the inner wall of fixed body 1 through sliding block 35 to ensure smooth movement. The downward movement of vertical plate 33 drives positioning block 34 to descend, thereby adjusting the distance between positioning block 34 and pressing block 22 to adapt to the fixing requirements of wires 4 of different diameters.

[0024] The above scheme is adopted: the top of the push rod 31 is connected to the bolt 21 through the fixing plate 311, and the bottom end is in the shape of an inclined surface. The rotation of the bolt 21 drives the push rod 31 to move up and down, thereby pushing the inclined block 32. The inclined block 32 overlaps the bottom end of the push rod 31 and the top end of the vertical plate 33. Both sides are in the shape of an inclined surface. Under the push of the push rod 31, it moves horizontally, and the vertical plate 33 is squeezed downward by the inclined surface to adjust the height of the positioning block 34. The top surface is fixedly connected to the connecting rod 321, which is connected to the fixing plate 311 through the connecting rod 321, and is provided with a first spring 322 to ensure the stability and reset ability of the movement of the inclined block 32. One side of the vertical plate 33 is fixedly connected to the sliding block 35, which slides on the inner wall of the fixed body 1 to ensure the stability of the movement of the vertical plate 33. The bottom surface is connected to the positioning block 34. 2 drives the positioning block 34 to move up and down under the extrusion. The bottom surface of the positioning block 34 is in an arc shape, which cooperates with the bottom surface of the pressure block 22 to fix the wire 4 together. The height of the positioning block 34 can be adjusted by moving the vertical plate 33. The torque head 25 is convenient for the operator to turn the bolt 21 by hand or tool to apply torque. The nut 26 is threadedly connected with the bolt 21 and installed inside the vertical cavity 102 to limit the axial movement of the bolt 21 and control the lifting and lowering of the pressure block 22 together with the bolt 21. There are two fixed plates 311, which are connected to the bolt 21 through a bearing. On the one hand, they are connected to the push rod 31, and on the other hand, they are connected to the sliding plate to transmit the movement of the bolt 21 and provide a connection point for the connecting rod 321 of the inclined block 32. The connecting rod 321 connects the inclined block 32 and the sliding plate, so that the movement of the inclined block 32 is connected to the fixed plate. The first spring 322 connects the connecting rod 321 and the bottom surface of the fixing plate 311 to provide a reset force for the inclined block 32. When the bolt 21 rotates in the opposite direction, the inclined block 32 can return to its initial position under the action of the first spring 322. The sliding block 35 connects the vertical plate 33 and the inner wall of the fixed body 1 to ensure that the vertical plate 33 slides smoothly in the fixed body 1 and guides the vertical plate 33 to move up and down. The second spring 36 connects the sliding block 35 and the stabilizing plate 361 to provide a reset force for the vertical plate 33. When the inclined block 32 no longer squeezes the vertical plate 33, the vertical plate 33 can return to its initial position under the action of the second spring 322. 36, returns to the initial position, the stabilizing sheet 361 is fixed to the inner wall of the fixed body 1, provides a support point for the second spring 36, enhances the stability of the second spring 36, and the adjustable spacing between the positioning block 34 and the wire 4 enables the fixing device to adapt to wires 4 of various diameters. Whether it is an electronic circuit wire 4 as thin as a hair or a power transmission wire 4 with a thick diameter, the best fixing spacing can be found by adjustment to ensure the firmness of the fixation. The pressing block 22 is lowered to apply pressure to the wire 4, and the positioning block 34 is adjusted to fit tightly, so as to form a stable clamp on the wire 4 from the upper and lower directions. This all-round fixing method can effectively resist external vibration, stretching and other forces, and ensure that the wire 4 can remain stable in various complex environments.Reduce the risk of electrical failure caused by loose wire 4. Since the entire fixing process is achieved by rotating the bolt 21, when the wire 4 needs to be replaced, adjusted or repaired, it is only necessary to reversely rotate the bolt 21 to easily release the fixation of the wire 4 and restore it to the initial adjustable state. This reversible and simple operation method greatly facilitates the subsequent maintenance work and reduces the maintenance cost and difficulty.

[0025] The working principle and use process of the present invention are as follows: the conductor 4 is placed on the bottom surface of the pressing block 22 to ensure that the conductor 4 is positioned accurately, and the torque head 25 on the top of the bolt 21 is turned by hand or a tool to rotate the bolt 21 clockwise, and the bolt 21 moves downward in the vertical cavity 102, driving the pressing block 22 to descend together, and as the pressing block 22 gradually approaches the conductor 4, pressure is applied to the conductor 4 until the conductor 4 is firmly fixed between the pressing block 22 and the base 5; At the same time, the bolt 21 drives the push rod 31 to move downward, the push rod 31 pushes the inclined block 32 to move horizontally, the inclined block 32 squeezes the vertical plate 33 to move downward, and the vertical plate 33 slides smoothly down on the inner wall of the fixed body 1 through the sliding block 35, thereby driving the positioning block 34 to descend, and adjusting the distance between the positioning block 34 and the wire 4 to better fix the wire 4; When it is necessary to remove the wire 4, the torque head 25 on the top of the bolt 21 is rotated in the opposite direction to make the bolt 21 rotate counterclockwise. The bolt 21 moves upward, driving the pressure block 22 to rise. At the same time, the push rod 31 moves upward, the inclined block 32 is reset under the action of the first spring 322, the vertical plate 33 is reset under the action of the second spring 36, and the positioning block 34 rises. When the pressure block 22 is out of contact with the wire 4, the wire 4 can be taken out.
