[0033] Embodiment 1

[0034] Referring to Figures 1 to 2 , which is the first embodiment of the present utility model. This embodiment provides an adjustment mechanism that can achieve the effect of placing multiple wires in the reserved opening and isolating external humid air from entering the box body 101. It includes that both sides of the [box body] are provided with receiving grooves 103a. Sliding grooves 103b are provided on both sides of the inner wall of the receiving groove 103a. A rubber clip 103c is slidably connected in the sliding groove 103b. The rubber clip 103c is a semi-circular fixture made of rubber. Two groups of rubber clips 103c are arranged in the receiving groove 103a. The wires are clamped between the two groups of rubber clips 103c. The rubber material itself has good elasticity and flexibility. Therefore, the rubber clip 103c made thereof can have a certain degree of elasticity, can adapt to wires of different sizes, can better fix and protect the clamped object during use, and can also reduce damage to the object. Moreover, the rubber clip 103c can fill the receiving groove 103a. During use, it can isolate external humid air from entering the box body 101. The opposite surfaces of the two groups of rubber clips 103c are wavy and cross-arranged, which makes the two groups of rubber clips 103c in...

[0035] It should be noted that there seems to be an incomplete sentence at the end of the text in item . If you have any further questions or need further assistance, please feel free to let me know.Further, an activity slot 201a is provided on the upper surface of the box body 101. The activity slot 201a communicates with the sliding slot 103b and the storage slot 103a. And an activity plate 201b is vertically and movably connected in the activity slot 201a. A sealing cover 102 is fixedly connected to the activity plate 201b. The sealing cover 102 is adapted to the box body 101 to achieve the effect of sealing the box body 101. It should be noted that the activity plate 201b is adapted to the notch of the storage slot 103a. When the activity plate 201b is inserted into the activity slot 201a, the notch of the storage slot 103a will be blocked by the activity plate 201b at this time.

[0036] Further, a pressing plate 201c is provided at the lower end of the activity plate 201b. The pressing plate 201c is trapezoidal in shape, and the other side is inclined. A stress plate 201d is provided at one side position of the rubber clip 103c in the sliding slot 103b. That is, the stress plates 201d on both sides are mirror-symmetrically arranged. One side of the stress plate 201d is also inclined, and is parallel and cooperates with the inclined surface of the pressing plate 201c.

[0037] When in use, vertically move the sealing cover 102 upward. Place the wire to be connected through the notch of the storage slot 103a at the upper end of the box body 101 and place it between the rubber clips 103c. According to the diameter of the wire, the rubber clip 103c drives the stress plate 201d to slide in the sliding slot 103b. After the wire connection is completed, align the activity plate 201b with the activity slot 201a and insert it. The inclined surface on one side of the activity plate 201b will contact the inclined surface on one side of the stress plate 201d and apply a downward pressure to it, which will cause the stress plates 201d on both sides to move towards the opposite side at the same time, thereby driving the rubber clip 103c to apply pressure to the wire until the rubber clip 103c deforms, so that there is no gap between the rubber clip 103c and the wire. And the part of the activity plate 201b in the storage slot 103a will simultaneously apply a downward pressure to the two groups of rubber clips 103c, so that there is no gap between the rubber clip 103c and the activity plate 201b. This makes the box body 101 reach a sealed state when the sealing cover 102 and the box body 101 are closed, solving the problem that the wires in the box body 101 will be affected by moisture and age and malfunction due to the humid external environment.

[0038] Embodiment 2

[0039] Refer to Figures 3 to 6, which is the second embodiment of the present utility model. Different from the previous embodiment, this embodiment provides a locking unit 200 of the locking component of the adjusting mechanism to solve the problem of how the sealing cover 102 maintains a stable connection with the sealing cover 102 when the sealing cover 102 and the box body 101 are closed. It includes a limiting block 202a provided on one inner wall of the movable groove 201a. The upper side of the limiting block 202a presents an inclined surface, and its lower end presents an arc-shaped arc surface 202e. And a fixing plate 202b is provided at a position near the lower end on one side of the movable plate 201b. One end of the fixing plate 202b is provided with a rotating shaft, and a torsion spring 202d is provided outside the rotating shaft. A rotating plate 202c is elastically connected through the torsion spring 202d. A cylindrical limiting rod 202f is provided at the lower end of the rotating plate 202c. Two limiting blocks 202a are horizontally arranged. The distance between the two limiting blocks 202a is equal to the widths of the fixing plate 202b and the rotating plate 202c. This enables the fixing plate 202b and the rotating plate 202c to be movably connected between the two limiting blocks 202a. However, the length of the limiting rod 202f is the distance between the front and rear parts of the two limiting blocks 202a. By setting the limiting rod 202f, when the rotating plate 202c is driven by the fixing plate 202b, it makes a passive rotational movement.

[0040] Further, a "convex"-shaped lifting groove 203a is opened on one inner wall of the movable groove 201a. A lifting rod 203b is slidably connected up and down in the lifting groove 203a. There are two groups of lifting rods 203b, which are respectively arranged at positions horizontally aligned with the limiting blocks 202a. Six inclined surfaces are provided on one inner wall of the lifting groove 203a between the two groups of lifting rods 203b. The upper and lower sides of the inclined surfaces are both inclined and parallel. And a pushing plate 203c is rotatably connected between the two groups of lifting rods 203b through a rotating shaft. There are five groups of pushing plates 203c, which are respectively arranged between the two inclined surfaces. The upper and lower sides of the pushing plate 203c are respectively in contact with the upper and lower groups of inclined plates 203d.

[0041] Among them, a reset groove 204a is formed in the upper inner wall of the lifting groove 203a. A spring 204b is arranged in the reset groove 204a, and the other end of the spring 204b is provided with a limiting plate 204c. The reset groove 204a having a "convex" shape means that the cross-sectional shape of the reset groove 204a is like a "convex" character protruding outward. Ensure that the limiting plate 204c can be firmly fixed in the reset groove 204a to prevent the limiting plate 204c from disengaging from the reset groove 204a. At this time, the spring 204b always applies an upward contraction elastic force. The lower end of the limiting plate 204c is fixedly connected to two groups of lifting rods 203b. And an adjustment groove 204d communicating with the four groups of lifting grooves 203a is formed at the center of the lower surface of the box body 101. The adjustment groove 204d has an "X" shape, and an "X" shaped connecting plate 204e is movably connected up and down on its inner wall and is fixedly connected to eight groups of lifting rods 203b respectively. A pull ring 204e is rotatably connected to the center position of the lower end of the connecting plate 204e, and the pull ring 204e is exposed on the lower side of the box body 101.

[0042] During use, when the movable plate 201b moves vertically downward in the movable slot 201a, the limiting rod 202f will come into contact with the uppermost limiting block 202a. The limiting rod 202f will exert a pressure on the inclined surface on the upper side of the limiting block 202a. Since the limiting block 202a is fixedly connected to the inner wall of the movable slot 201a, with the continuous downward displacement of the movable plate 201b, the limiting rod 202f rotates counterclockwise, the torsion spring 202d is subjected to a torsional effect and undergoes elastic deformation, storing mechanical energy. Along with the rotation of the limiting rod 202f until the limiting rod 202f disengages from the limiting block 202a, at this time the pressure on the limiting rod 202f disappears, the torque of the torsion spring 202d disappears, and the torsion spring 202d releases the stored mechanical energy, driving the limiting rod 202f to return to the initial state. At this time, the limiting rod 202f will fit with the arc plate. When there is still a gap between the rubber clip 103c and the wire at this time, it will allow the movable plate 201b to continue to move downward. The limiting rod 202f will then contact the next-level limiting block 202a until the movable plate 201b can no longer move downward, and it will be limited on the arc surface 202e of the appropriate limiting block 202a, achieving the effect of fixing the sealing cover 102 at this time and simultaneously fixing the clamping position of the rubber clip 103c at this time. When it is necessary to open the sealing cover 102, it is necessary to disengage the limiting rod 202f from the arc surface 202e. The operator needs to first pull the pull ring 204e. Driven by the pull ring 204e, eight sets of lifting rods 203b are simultaneously driven to move downward through the connecting plate 204e. Connected to the limiting plate 204c, a downward pulling force is exerted on the spring 204b, causing the spring 204b to deform and store elastic potential energy. At the same time, the lifting rods 203b will simultaneously drive five sets of push plates 203c to move downward. The lower side of the push plate 203c will exert a pressure on the upper inclined surface of the inclined plate 203d. Due to the large inclination angle of the upper inclined surface of the inclined plate 203d, the push plate 203c is driven to rotate clockwise passively and comes into contact with one side surface of the rotating plate 202c. As the lifting rod 203b continues to descend, the lower end of the push plate 203c will push the rotating plate 202c to rotate counterclockwise. The torsion spring 202d is subjected to a torsional effect and undergoes elastic deformation, storing mechanical energy. At the same time, the limiting rod 202f gradually disengages from the arc surface 202e. When the pull ring 204e can no longer be pulled, it means that the lower surface of the limiting plate 204c comes into contact with the inner wall of the reset slot 204a at this time, and the limiting plate 204c has moved to the maximum movable range, which means that the limiting rod 202f disengages from the arc surface 202e under the drive of the push plate 203c pushing the rotating plate 202c and is no longer within the limiting range of the limiting block 202a. At this time, the sealing cover 102 can be pulled upward, but the pull ring 204e needs to be kept stationary. As the sealing cover 102 moves, the movable plate 201b will be displaced, so that the rotating plate 202c disengages from the current push plate 203c under the drive of the fixed plate 202b.After detachment, the pressure on the rotating plate 202c disappears, the torque of the torsion spring 202d disappears, the torsion spring 202d releases the stored mechanical energy, and drives the rotating plate 202c to return to the initial state. However, under the pulling of the pull ring 204e, the five sets of push plates 203c always remain in the same position. This causes the rotating plate 202c to continue to rotate counterclockwise under the movement of the movable plate 201b when it returns to the initial state until the movable plate 201b disengages from the movable groove 201a, and the sealing cover 102 is removed. At this time, the pull ring 204e can be released to complete the disassembly work. By such a setting, the sealing performance and stability of the box body 101 and the sealing cover 102 can be improved.

[0043] Embodiment 3

[0044] Referring to Figures 6 to 8 , which is the third embodiment of the present utility model. Different from the previous embodiment, this embodiment provides a junction box, which solves the problem that the connection of wires in the box body 101 is restricted by the size and shape and cannot be connected. It includes the adjustment mechanism in the above embodiment, including a wiring board 301 arranged in the box body 101. A placement groove 302 is arranged in the wiring board 301, and the wires enter the placement groove 302 through the storage grooves 103a on both sides for connection.

[0045] Specifically, five sets of connection components 303 are arranged in the wiring board 301. The connection component 303 includes a knob 303c threadedly connected to the upper side surface of the wiring board 301. The lower end of the knob 303c is rotatably connected to a clamping rod 303d. The cross-sectional shape of the lower end of the knob 303c is like a "convex" character protruding outward, which enables the knob 303c to rotate on the clamping rod 303d without detaching from the clamping rod 303d. A fixing rod 303a is arranged at a position on the inner wall of the placement groove 302 opposite to the clamping rod 303d. A positioning hole 303b is arranged at the center axis of the upper end surface of the fixing rod 303a in a mirror image manner. The lower end of the clamping rod 303d is in an inverted "U" shape and is matched with the positioning hole 303b. The lower end of the clamping rod 303d is disassembled in the positioning hole 303b, which enables the clamping rod 303d not to rotate when the knob 303c rotates while being inserted into the positioning hole 303b. At the same time, clamping ring pieces 303e are arranged outside both the clamping rod 303d and the fixing rod 303a. The clamping ring pieces 303e can expand the connection range of the clamping rod 303d and the fixing rod 303a and can adapt to the connection heads of the wires. It should be noted that the clamping ring pieces 303e, the clamping rod 303d, and the fixing rod 303a are all made of materials with good electrical conductivity.

[0046] When in use, when there is no connector on the wire and only copper wire, the copper wire can be placed inside the lower end of the clamping rod 303d. Under the rotation of the knob 303c, the clamping rod 303d will tightly clamp the copper wire between the inner side of the clamping rod 303d and the upper side of the fixed rod 303a. When there is a connector on the wire, the connector can be sleeved outside the clamping rod 303d and below the clamping ring 303e of the clamping rod 303d. Under the rotation of the knob 303c, the connector is tightly clamped in the middle by the two upper and lower clamping rings 303e for fixation.
