[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0033] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing embodiments of the present invention, cross-sectional views of device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, three-dimensional dimensions, including length, width, and depth, should be included.

[0034] Example 1

[0035] Reference Figures 1 to 3 , which is the first embodiment of the present invention, provides a wire fixing mechanism that can achieve the effect of fixing multiple wire harnesses on the inner walls on both sides of the interior of the electrical cabinet, including an installation unit 100, including a cabinet body 101, a connecting frame 102 set in the cabinet body 101, and a connecting component 103 set on the connecting frame 102; a fixing unit 200, including a fixing plate 201, a pressing component 202 set on the other side of the fixing plate 201, and a pressing component 203 set on the other side of the fixing plate 201. The fixing component 203 and the tightening component 204 arranged in the fixing plate 201 and matched with the fixing component 203, the inner walls on both sides of the cabinet 101 are symmetrically provided with several connecting frames 102, and the other side of the connecting frame 102 is evenly distributed with several groups of L-shaped parts 103a, and the L-shaped parts 103a are L-shaped, which means that there is a gap between the L-shaped parts 103a and the other side surface of the connecting frame 102. A small number of wiring harnesses can be placed in this gap. When there are more wiring harnesses that need to be fixed, the fixing plate 201 can be installed on the L-shaped parts 103a.

[0036] Specifically, a movable groove 202a is opened inside the fixed plate 201, and the movable groove 202a runs through the two side surfaces of the fixed plate 201, and a push plate 202b is slidably connected in the movable groove 202a, and the push plate 202b is in the shape of an "I", and its other end is exposed on the other side of the fixed plate 201. One end of the push plate 202b slides in the movable groove 202a, and a return spring 202c is elastically connected between the push plate 202b and the movable groove 202a, which always applies a contraction elastic force to the push plate 202b in the direction of the other side.

[0037] Furthermore, connecting blocks 202d are fixedly mounted on one side of the push plate 202b near the front and rear portions. A fixing rod 202e is disposed between the two connecting plates. Arc-shaped slots 103b are provided at the corners of the inner wall of the L-shaped member 103a. Arc-shaped slots 103b mate with the fixing rods 202e, leaving a gap between the outer wall of the fixing rod 202e and one side of the push plate 202b. This gap is wider than the width of the upper end of the L-shaped member 103a, allowing the L-shaped member 103a to pass through between the fixing rod 202e and the push plate 202b. A reinforcement block 202f is provided at the upper end of the fixing plate 201.

[0038] When in use, when the L-shaped piece 103a can no longer meet the wiring requirements in the cabinet 101, we can install the fixing plate 201 to fix the wiring harness. First, press the push plate 202b to move to one side, so that the push plate 202b applies a pulling force to one side on the return spring 202c, causing the return spring 202c to extend to one side and store elastic potential energy. When the push plate 202b cannot be pressed, one side of the push plate 202b is in contact with the inner wall of one side of the movable groove 202a, which means that the gap between the fixing rod 202e and the pushing plate 202b exposed on one side of the fixing plate 201 can allow the L-shaped piece 103a to pass through. Move the fixing rod 202e into the gap between the L-shaped piece 103a and the connecting frame 102, and push the fixing rod 202e to the gap between the L-shaped piece 103a and the connecting frame 102. The fixing rod 202e is prevented from returning to its original position by the obstruction of the L-shaped member 103a and can only be limited in the arc groove 103b. However, the fixing rod 202e will always move to the other side, and the fixing rod 202e and the arc groove 103b will conflict with each other, thus achieving the effect of fixing the L-shaped member 103a and the fixing plate 201 together. At this time, the reinforcing block 202f will also fill the gap between the connecting plate and the L-shaped member 103a, avoiding the situation where there are too many wire harnesses on the fixing plate 201 and the fixing plate 201 will bend.

[0039] Example 2

[0040] Reference Figures 4 to 7, which is the second embodiment of the present utility model. Different from the previous embodiment, this embodiment provides a fixing component 203 of the wire fixing mechanism, which solves the problem of how to fix the wire harness on the fixed plate 201, including a placement groove 203a on the other side surface of the fixed plate 201, and the placement groove 203a is used to place the wire harness that needs to be stored and organized. A belt discharge groove 203b is provided on the other side surface of the fixed plate 201 between the placement groove 203a and the movable groove 202a.

[0041] Furthermore, the belt groove 203b is in the shape of a letter "b", and transmission grooves 204c are provided on both sides of the inner wall of the belt groove 203b, and a connecting rod 203c is rotatably connected therebetween via a rotating shaft. A spring 204d is provided in the transmission groove 204c, and one end of the spring 204d is connected to the transmission groove 204c, and one end of the spring 204d is connected to the connecting rod 203c. A fixed line belt 203d is fixedly connected to the outside of the connecting rod 203c in the belt groove 203b. The fixed line belt 203d is wound multiple times around the outside of the connecting rod 203c, and the other end of the fixed line belt 203d is exposed on the transmission groove 204c. Outside the slot 204c, the fixing band 203d is elastically connected to the clockwork spring 204d through the connecting rod 203c. When the fixing band 203d extends outward, it will drive the connecting rod 203c to rotate, thereby driving the clockwork spring 204d to contract inward, causing the clockwork spring 204d to be twisted, and converting energy into elastic potential energy. When the fixing band 203d is stretched at the same time and the outward pulling force disappears, the clockwork spring 204d begins to release the stored energy. At this time, the clockwork spring 204d will gradually return to an untwisted or unstretched state, and drive the fixing band 203d to be rewound through the connecting rod 203c.

[0042] Furthermore, a cylindrical positioning rod 204a is provided at the other end of the fixing belt 203d, and its diameter is larger than the slot of the belt discharge groove 203b. This prevents the fixing belt 203d from being completely retracted into the belt discharge groove 203b under the elastic force of the clockwork spring 204d, and the positioning rod 204a will be exposed. A positioning arc plate 204b is provided on the other side of the fixed plate 201 near the upper end. The positioning arc plate 204b is semicircular and equal to the positioning rod 204a, so that the positioning rod 204a can be movably connected to the inner side of the positioning arc plate 204b.

[0043] When in use, after the placement slot 203a has stored all the wiring harnesses, the positioning rod 204a can be pulled to the other side, driving the wire fixing belt 203d to move outward, thereby driving the connecting rod 203c to rotate, thereby driving the spring spring 204d to contract inward, causing the spring spring 204d to be twisted, and converting the energy into elastic potential energy. When the wire fixing belt 203d has wrapped all the wiring harnesses, the fixing rod 202e can be placed on the inner side of the positioning arc plate 204b, and the positioning rod 204a can be loosened, and the wire fixing belt 203d can be moved outward. When the pulling force disappears, the clockwork spring 204d begins to release the stored energy, and the wire fixing belt 203d will apply a downward pulling force to the positioning rod 204a, but the positioning rod 204a is blocked by the positioning arc plate 204b and cannot be reset. This prevents the positioning rod 204a from detaching from the positioning arc plate 204b, thereby driving the slot of the placement slot 203a to be blocked, preventing the wiring harness inside it from detaching, thus achieving the effect of fixing the wiring harness. It is also very convenient to repair and replace the wiring harness. You only need to take the positioning rod 204a out of the positioning arc plate 204b.

[0044] Example 3

[0045] Reference Figures 8 and 9 , which is the third embodiment of the present utility model. Different from the previous embodiment, this embodiment provides an electrical cabinet, which solves the problem that after the equipment is fixed by the support frame 301, the fixed position often cannot be adjusted. It is a more troublesome problem when the position of the equipment needs to be adjusted, including the wire fixing mechanism in the above embodiment, including the support unit 300, including the support frame 301, the elliptical groove 302 arranged on the front and rear surfaces of the support frame 301, the support frame 301 is arranged between the connecting frame 102, and the limiting component 303 arranged in the support frame 301 and matched with the connecting frame 102, the support frame 301, the support frame 301 is arranged between the connecting frames 102 on both sides of the cabinet body 101, and the support frame 301 presents a "working " shape, the two ends of the support frame 301 are adapted to the connecting frame 102 and can slide on the inner side of the connecting frame 102, and a rectangular sliding groove 303a is opened inside it, and a limiting plate 303b is slidably connected in the sliding groove 303a. There are two sets of limiting plates 303b, which are mirrored with the central axis of the sliding groove 303a, and a rectangular hole 303c is opened on the opposite surface of the connecting frame 102. The rectangular hole 303c matches the limiting plate 303b, and the limiting plate 303b can be inserted into the rectangular hole 303c.

[0046] Furthermore, the displacement assembly 304 includes a through slot 304a provided on the front surface of the support frame 301, a toggle slot 304b provided on the front surface of the limiting plate 303b, a circular hole 304c provided on the limiting plate 303b, and a knob 304d provided in the circular hole 304c; the knob 304d is threadedly connected to the inner wall of the sliding slot 303a;

[0047] Two groups of through grooves 304a are provided on the front surface of the support frame 301, and the toggle grooves 304b provided on the front surfaces of the two groups of limit plates 303b are aligned with each other, so that the limit plates 303b can be moved by depressing the toggle grooves 304b, and several groups of elliptical grooves 302 are provided on the front and rear parts of the support frame 301 and the limit plates 303b. The design of the elliptical grooves 302 allows bolts to pass through the support frame 301 and the limit plates 303b in turn to connect with the equipment. By adjusting the tightness of the threaded connection, the equipment can be fixed at the desired position and angle to ensure the accuracy and stability of the assembly.

[0048] Specifically, circular holes 304c are provided on both sets of limiting plates 303b and are aligned with each other. A knob 304d is connected through the front of the support frame 301. The knob 304d passes through the two sets of circular holes 304c in turn and is threadedly connected to the inner wall of the sliding groove 303a. This achieves the purpose of fixing the two sets of limiting plates 303b together and fixing the position of the limiting plates 303b at this moment to prevent the limiting plates 303b from moving.

[0049] When the two limit plates 303b are in contact with each other, the limit plates 303b will be completely limited in the sliding grooves 303a, and there will be no protruding parts at both ends of the support frame 301, which allows the support frame 301 to slide between the two connecting frames 102. When the position of the support frame 301 is determined, the limit plates 303b can be toggled to both sides through the toggle grooves 304b until the limit plates 303b are inserted into the rectangular holes 303c, and then the elliptical grooves 302 on the limit plates 303b are aligned with the elliptical grooves 302 on the support frame 301. After alignment, it means that the two sets of circular holes 304c are aligned, and the knob 304d can be inserted and screwed into the movable groove 202a by rotating forward. At this time, the limit plates 303b are fixed, and the position of the support frame 301 is fixed, and the device can be installed between the support frame 301 and the control panel.
