Description

Technical Field

[0001] The utility model relates to the technical field of distribution boxes, in particular to a clamping mechanism and an adjustable distribution box. Background Art

[0002] A distribution box is a device used to distribute electricity and protect electrical equipment. The main function of a distribution box is to distribute electrical energy from the main power supply to different circuits and equipment, and to cut off the current when necessary to protect equipment and personnel safety. Distribution boxes are widely used in homes, commercial buildings, and industrial sites. The wires used for connection in existing distribution boxes are usually fixed by cable ties, which can ensure that the wires are arranged in an orderly manner inside the distribution box and avoid messy line layout. This helps to reduce the crossing and confusion between wires, reducing the risk of short circuits or fires.

[0003] However, there are disadvantages to using cable ties to fix wires. Once the wires are fixed with cable ties, it becomes difficult to readjust or move the wires. This will result in the need to cut the cable ties and re-fix the wires when wiring adjustments or new equipment is needed in the future, increasing the complexity of maintenance and wiring. Although cable tie fixing makes maintenance easier, when a single wire needs to be replaced or adjusted, the cable ties need to be cut and re-fixed, which increases maintenance time and labor costs. The electrical equipment installed in the distribution box has differences in size and height, and the beams used to fix and position the electrical equipment are usually fixed, which leads to a lack of flexibility in the installation and adjustment of the electrical equipment.

[0029] In order to make the above-mentioned purposes, 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 in conjunction with the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and 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.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in 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.

[0032] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0033] Example 1

[0034] Reference Figure 1 to Figure 2 , is the first embodiment of the utility model, which provides a clamping mechanism that can achieve the effect of clamping and fixing multiple wires, including an installation unit 100, including a box body 101, and an electrical connector 102 arranged in the box body 101; a clamping unit 200, including a connecting component 201 arranged in the box body 101, a rotating component 202 arranged on the connecting component 201, a clamping component 203 arranged on the rotating component 202, and a fixing component 204 arranged on the clamping component 203.

[0035] Specifically, a magnetic plate 201b is embedded in the rear part of the fixing plate 201a. Since the existing boxes 101 are all made of iron, the fixing plate 201a can be firmly fixed inside the distribution box by the magnetic adsorption of the magnetic plate 201b. Using the magnetic plate 201b can make the installation process of the fixing plate 201a more convenient, without the need for additional screws or other fixing parts. The connecting seat 202a is rotatably connected to the front part of the fixing plate 201a through a rotating seat 201c. Rotating grooves 202b are opened on both sides of the connecting seat 202a, and rotating seats 202c are respectively rotatably connected in the rotating grooves 202b by arranging rotating shafts. Limiting arc plates 203b are fixedly connected near the upper and lower ends of the rotating seat 202c on one side. The two limiting arc plates 203b form a U-shaped structure, that is, there is a gap between the two limiting arc plates 203b. An adjusting arc plate 203c is fixedly connected to the rotating seat 202c on the other side. The adjusting arc plate 203c is adapted to the gap between the two limiting arc plates 203b.

[0036] During use, due to the layout requirements of the wire arrangements of some electronic devices, the wires are operated horizontally and vertically. Thus, the connecting seat 202a can be rotated 360 degrees through the rotating seat 201c to achieve the effect of adapting to the wiring layout. The adjusting arc plate 203c and the limiting arc plate 203b form a circular ring structure. The wires are received into the circular ring structure. Through the outer sides of the adjusting arc plate 203c and the limiting arc plate 203b, the adjusting arc plate 203c and the limiting arc plate 203b will rotate relative to each other with the rotating seat 202c as the center. As a result, the adjusting arc plate 203c passes through the gap between the two limiting arc plates 203b, so as to reduce the range of the circular ring formed by the adjusting arc plate 203c and the limiting arc plate 203b, and thus achieve the effect of clamping the wires in the circular ring structure.

[0037] Embodiment 2

[0038] Referring to Figures 4 to 6 , this is the second embodiment of the present utility model. Different from the previous embodiment, this embodiment provides a locking unit 300 for the clamping mechanism to solve the problem that the adjusting arc plate 203c and the limiting arc plate 203b cannot be fixed during the clamping process. The locking unit 300 includes a reset component 301 arranged on the clamping component 203, a pressing component 302 arranged on the clamping component 203, and a pressing component 303 arranged on the clamping component 203. Two groups of locking units 300 are arranged in the adjusting arc plate 203c.

[0039] Furthermore, a displacement groove 204a is provided in the adjustment arc plate 203c, and a lifting plate 204b is connected to the displacement groove 204a for vertical movement, and a plurality of adjustment blocks 204c are provided on the upper part of the lifting plate 204b, and the adjustment blocks 204c penetrate the upper surface of the adjustment arc plate 203c and are movably connected to the upper part of the adjustment arc plate 203c up and down. A telescopic groove 301a is provided at the bottom of the lifting plate 204b near the two sides, and a spring 301b is fixedly connected in the telescopic groove 301a, and the spring 301b is connected to a positioning rod 301c fixedly connected to the inner wall of the displacement groove 204a. The existence of the positioning rod 301c can limit the movement range of the lifting plate 204b, and the design of the telescopic groove 301a allows the spring 301b to be telescoped within a certain range, and cooperates with the positioning rod 301c to achieve the effect of resetting the lifting plate 204b, and the opposite surfaces of the two limiting arc plates 203b are provided with a plurality of fixed blocks 204d.

[0040] Among them, the fixed block 204d is triangular in shape, and a "V"-shaped structure is formed between the two fixed blocks 204d. The adjusting block 204c is also triangular in shape and is compatible with the "V"-shaped structure formed by the fixed block 204d. When the adjusting arc plate 203c and the limiting arc plate 203b intersect each other, the fixed block 204d will apply an extrusion force to the adjusting block 204c, thereby pushing the lifting plate 204b to move downward, thereby applying pressure to the spring 1 301b, thereby causing the spring 1 301b to deform and store elastic potential energy. When the fixed block 204d no longer squeezes the adjusting block 204c, the adjusting block 204c will be limited in the "V"-shaped structure, which can enhance the stability between the adjusting arc plate 203c and the limiting arc plate 203b, making it more stable and reliable when clamping the wire.

[0041] Further, a triangular groove is formed on the other side of the lifting plate 204b, and an extrusion inclined surface 302a is provided. A limiting groove 302b is formed on the inner wall of the other side of the displacement groove 204a. An extrusion plate 302c horizontally moves in the limiting groove 302b. The upper and lower parts of the extrusion plate 302c are in contact with the inner wall of the limiting groove 302b, which limits the position of the extrusion plate 302c and allows it to only move horizontally up and down. One side of the extrusion plate 302c is provided with an inclined surface one 302d, and the other side is provided with an inclined surface two 302e. The inclined surface one 302d is parallel to the extrusion inclined surface 302a and always remains in contact with each other. A pressing plate 303a in contact with the inclined surface two 302e is movably connected in the limiting groove 302b and penetrates through the outside of the adjusting arc plate 203c and is exposed outside. The pressing plates 303a in the upper and lower groups are connected by a connecting block 303b. The connecting block 303b is in the shape of "丄". And a sliding groove 303c is formed between the inner walls of the displacement grooves 204a on the upper and lower sides inside the adjusting arc plate 203c. The sliding groove 303c is adapted to the connecting groove, and its function is to provide guidance and fixation. The connecting block 303b can slide along a certain track in the sliding groove 303c, so as to maintain the stable position of the pressing plate 303a and prevent it from shifting or shaking during the movement process.

[0042] During use, simply relying on the fixing block 204d to squeeze the adjusting block 204c and repeatedly moving the adjusting block 204c up and down will cause wear of the adjusting block 204c. At this time, we can push the pressing plate 303a towards the inner side of the adjusting arc plate 203c. The inclined surface on one side of the pressing plate 303a will exert a squeezing force in one direction on the inclined surface two 302e, thereby pushing the extrusion plate 302c to move in one direction. As a result, the inclined surface one 302d on one side of the extrusion plate 302c exerts a squeezing force on the extrusion inclined surface 302a, so that the lifting plate 204b moves downward and exerts a downward pressure on the spring one 301b, deforming it, and driving the adjusting block 204c to move downward. The adjusting blocks 204c on the upper and lower sides of the adjusting arc plate 203c simultaneously contract inward. At this time, by拨动 the adjusting arc plate 203c and the limiting arc plate 203b (the specific operation of "拨动" is not clear in the original text, it may be a misspelling or an unclear description, but it is translated as "拨动" here), the fixing block 204d will have no resistance until the inner sides of the adjusting arc plate 203c and the limiting arc plate 203b contact the wire, and then the pressing plate 303a can be released. Without the pressure exerted by the lifting plate 204b, the spring one 301b, under the action of the stretching elastic force, pushes the lifting plate 204b upward, which will cause the adjusting block 204c to be limited within the "V" - shaped structure of the fixing block 204d, achieving the effect of clamping and fixing the adjusting arc plate 203c and the limiting arc plate 203b. When unlocking the clamping state of the adjusting arc plate 203c and the limiting arc plate 203b, the pressing plate 303a is also pushed to unlock.

[0043] Embodiment 3

[0044] Reference Figure 7 to Figure 7 , which is the third embodiment of the utility model. Different from the previous embodiment, this embodiment provides an adjustable distribution box, which solves the problem that the beam 402 cannot be adjusted. It includes the clamping mechanism in the above embodiment, including an adjustment unit 400, including an adjustment slot 401 arranged in the box body 101, a beam 402 arranged in the adjustment slot 401, and a limit assembly 403 arranged in the adjustment slot 401 and matched with the beam 402.

[0045] Specifically, the limiting assembly 403 includes a spring 403a disposed in the adjusting groove 401, a push plate 403b disposed on the spring 403a, a receiving groove 403c disposed in the adjusting groove 401, and a rotating block 403d disposed in the receiving groove 403c. The adjusting groove 401 is provided at both sides of the inner wall of the box body 101, and a plurality of receiving grooves 403c are provided. The inner wall of the adjusting groove 401 is provided with a receiving groove 403c near the upper side. The inner wall of the receiving groove 403c is connected to a rotating block 403d by rotating near the front. The rotating block 403 The front part of d fits into the front side of the inner wall of the storage groove 403c, which makes the front part of the rotating block 403d conflict with the inner wall of the storage groove 403c, so that the rotating block 403d cannot rotate clockwise but can only rotate counterclockwise. Due to the gravity factor, the other end of the rotating block 403d is vertically downward. When the rotating block 403d rotates 90 degrees counterclockwise, the entire rotating block 403d will be limited in the storage groove 403c, and the bottom of the inner wall of the adjustment groove 401 is fixedly connected with a spring 2 403a, and several springs 2 403a are commonly fixedly connected with a push plate 403b.

[0046] When in use, place the crossbeam 402 in a suitable adjustment slot 401, push the crossbeam 402, the rear end of the crossbeam 402 will contact the rotating block 403d and apply a backward force to the rotating block 403d, thereby causing the rotating block 403d to rotate counterclockwise. When the rotating block 403d is limited in the storage slot 403c, the crossbeam 402 passes over the rotating block 403d. The rotating block 403d will rotate clockwise perpendicular to the horizontal plane under the factor of gravity without the thrust applied by the crossbeam 402. During this movement, the rear end of the crossbeam 402 will contact the push plate 403d. 03b contacts and applies a backward thrust to it, causing spring 2 403a to contract backward to store elastic potential energy. When beam 402 passes over, beam 402 can be released, and the pressure on spring 2 403a disappears, and the beam 402 is pushed forward by the stretched elastic force. Since the front part of rotating block 403d conflicts with the inner wall of storage groove 403c, beam 402 can no longer move forward, thereby achieving the effect of fixing beam 402. Through such a design, beam 402 can be easily and flexibly adjusted.
