Description

Technical Field

[0001] The present invention relates to the technical field of distribution boxes, and particularly relates to a power distribution device with an adjustable damping structure. Background Art

[0002] A water conservancy project is a project built for controlling and allocating surface water and groundwater in nature to achieve the purpose of eliminating disasters and bringing benefits. Currently, on the construction site of a water conservancy project, a distribution box is one of the most common power distribution devices, which can integrate various electrical cables inside the distribution box for sorting and control, facilitating various construction operations of the water conservancy project.

[0003] However, for the currently existing distribution boxes used at construction sites, their door leaves can rotate freely after being unlocked, without locking and damping limit structures. And since distribution boxes are generally used outdoors, when the door leaves are opened for repairing or replacing internal cables or switches, the door leaves will rotate freely, affecting the operation of construction workers, with poor stability and low practicability.

[0014] Beneficial effects

[0015] 1. The door lock assembly can position the usage state of the cabinet door, so as to maintain the closed and open states of the distribution box for use. The function assembly enables the cabinet door to have three usage modes: free mode, damping mode, and adaptive locking mode. In the free mode, the cabinet door can rotate freely after being opened. In the damping mode, there is a certain damping force when the cabinet door rotates after being opened. In the adaptive locking mode, after the cabinet door is opened, the opening position and angle of the cabinet door can only be adjusted and positioned by the door lock assembly, and the cabinet door cannot rotate freely. The three usage modes can be freely switched. At the same time, the rotational damping force of the cabinet door in the damping mode can also be freely adjusted, which can adapt to power distribution use at water conservancy construction sites in different environments, improving the flexibility, stability, adaptability, and practicality of the device.

[0016] 2. The door lock assembly can realize the locking and unlocking control of the cabinet door. When the door lock assembly is in the reset state, under the action of the locking top spring, one end of the locking tongue rod extends out of the cabinet door, so that the locking tongue rod can be inserted into the lock hole of the cabinet body, thereby realizing the closing and locking of the distribution box for use. When the cabinet door needs to be opened, just rotate the unlocking handle. When the unlocking handle rotates, the unlocking gear can drive the locking tongue rod to move to one side, so that the locking tongue rod disengages from the inside of the lock hole. And when the unlocking gear rotates, it can drive the control rod to move synchronously and in the opposite direction to the locking tongue rod through the synchronous rack. When the control rod moves, the linkage rod can drive the control seat to move downward synchronously through the linkage groove and compress the locking top spring, thereby releasing the tooth engagement relationship between the synchronous gear and the control gear. After that, the cabinet door can rotate freely to open, which is convenient and flexible to use.

[0017] 3. Since the teeth of the control gear and the synchronous gear are engaged with each other when the door lock assembly is in the reset state, the switching and use between the three usage modes of the cabinet door can be realized by controlling and adjusting the usage and movement states of the control gear. That is, when the adjusting screw is fixed and the switching screw is rotated alone, the switching screw can move up and down inside the adjusting screw through the rod thread to change the usage position of the switching disc, thereby realizing the switching use of the three usage modes of the cabinet door, with convenient operation and flexible use.

[0018] 4. When the switching disk is located at the top of the functional empty slot, the cabinet door is in the damping mode at this time. That is, when the cabinet door is opened and the door lock assembly is in the reset state, there is a certain damping force when the cabinet door rotates. In this mode, under the action of the damping top spring, the damping tooth groove is inserted outside the damping tooth ring, and there is enough space at the bottom groove body of the functional empty slot for the functional seat to move upward when the cabinet door rotates. Thus, when the cabinet door rotates at this time, the cabinet door can drive the control gear to rotate synchronously through the synchronous gear. Under the action of the positioning groove, the functional seat can never rotate by itself. Therefore, when the control gear rotates, the teeth of the damping tooth ring can squeeze against the tooth groove hypotenuse of the damping tooth groove, and the functional seat will automatically compress the damping top spring upward to avoid the rotation of the control gear. After rotating a distance of one tooth of the damping tooth ring, under the action of the damping top spring, the damping tooth groove can be inserted outside the damping tooth ring again, thus completing the triggering of a single damping effect. That is, when the cabinet door continues to rotate, the damping effect will be continuously triggered, which is convenient to use and makes the cabinet door not rotate freely under the action of a small external force during use, and the use is stable.

[0019] 5. The rotation resistance of the cabinet door in the damping mode can be adjusted by the adjusting screw. When the adjusting screw is rotated, the adjusting screw can drive the positioning disk to move up and down inside the positioning groove through the rod thread, thereby changing the initial stretching length of the damping top spring, and thus changing the force required to compress the damping top spring when triggering the damping effect, that is, the damping force, which can meet the use requirements of different damping forces and has extremely strong adaptability.

[0020] 6. When the switching disk is located at the bottom of the functional empty slot, the cabinet door is in the adaptive locking mode at this time. Since the switching disk is located at the bottom of the functional empty slot, the functional seat cannot move upward, so the damping tooth groove is always inserted outside the damping tooth ring, making the control gear locked and unable to rotate. At this time, the cabinet door can only rotate after unlocking the door lock assembly, and the cabinet door can be automatically locked at the use angle and position after the door lock assembly is reset. When the door lock assembly is in the reset state, the control gear can make the cabinet door unable to rotate freely through the synchronous gear. When the door lock assembly is unlocked, the synchronous gear can lose the tooth engagement relationship with the control gear, so that the cabinet door can rotate freely, which can realize the real-time locking and regulation of the cabinet door, and further improve the adaptability and flexibility of the device.

[0021] 7. When continuously rotating the switching screw to drive the switching disk to move upward continuously, the switching disk can abut against the top of the functional empty slot and drive the functional seat to move upward synchronously, so that the damping tooth groove is always disengaged from the outside of the damping tooth ring. Thereafter, the cabinet door is in the free mode. In this mode, the control gear can rotate freely, and thus the cabinet door can also rotate freely. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Among them, one end of the rotating shaft of the unlocking handle 202 is provided with an unlocking gear 2021, and synchronous racks 2031 are provided on the sides of the locking tongue rod 201 and the control rod 203. The synchronous racks 2031 of the locking tongue rod 201 and the control rod 203 are respectively engaged with the teeth of the unlocking gear 2021 for transmission. During use, the door lock assembly 2 can realize the locking and unlocking control of the box door 102. When the door lock assembly 2 is in the reset state, a locking top spring 2043 is arranged inside the control seat 204, and both ends of the locking top spring 2043 respectively abut against the inside of the control seat 204 and the box door 102. Under the action of the locking top spring 2043, one end of the locking tongue rod 201 is in a state of protruding from the box door 102, so that the locking tongue rod 201 can be inserted into the lock hole inside the box body 101, thereby realizing the closing and locking use of the distribution box 1. When it is necessary to open the box door 102, only need to rotate the unlocking handle 202. When the unlocking handle 202 rotates, the unlocking gear 2021 can drive the locking tongue rod 201 to move to one side, so that the locking tongue rod 201 is withdrawn from the inside of the lock hole. And when the unlocking gear 2021 rotates, it can drive the control rod 203 to move in the same direction asynchronously with the locking tongue rod 201 through the synchronous rack 2031. One end of the control rod 203 is provided with a linkage rod 2032, and an inclined linkage groove 2041 is arranged inside the control seat 204. The linkage rod 2032 is inserted into the linkage groove 2041. When the control rod 203 moves, the linkage rod 2032 can drive the control seat 204 to move downward synchronously through the linkage groove 2041 and compress the locking top spring 2043, thereby releasing the tooth engagement relationship between the synchronous gear 2042 and the control gear 301. After that, the box door 102 can be freely rotated and opened, which is convenient and flexible to use.

[0045] Among them, a synchronous gear 2042 is arranged on the top of the control seat 204, and the teeth of the synchronous gear 2042 and the control gear 301 are engaged for transmission. The synchronous gear 2042 and the box door 102 are on the same rotation axis. During use, since the teeth of the control gear 301 and the synchronous gear 2042 are engaged with each other when the door lock assembly 2 is in the reset state, the switching and use between three use modes of the box door 102 can be realized by controlling and adjusting the use and movement states of the control gear 301. That is, when the adjusting screw 304 is fixed and the switching screw 303 is rotated alone, the switching screw 303 can move up and down inside the adjusting screw 304 through the screw thread of the rod body to change the use position of the switching disc 3031, thereby realizing the switching use of three use modes of the box door 102, with convenient operation and flexible use.

[0046] Among them, a damping tooth ring 3011 is provided at the top of the control gear 301, and a damping tooth groove 3021 is provided at the bottom of the function seat 302. The cross-sectional shapes of a single tooth of the damping tooth ring 3011 and a single tooth groove of the damping tooth groove 3021 are both triangular, and the damping tooth ring 3011 is inserted inside the damping tooth groove 3021. During use, when the switching disk 3031 is located at the top of the function empty groove 3022, the box door 102 is in the damping mode at this time, that is, when the box door 102 is opened and the door lock assembly 2 is in the reset state, there is a certain damping force when the box door 102 rotates. In this mode, under the action of the damping top spring 3051, the damping tooth groove 3021 is inserted outside the damping tooth ring 3011, and there is sufficient space left at the bottom groove body of the function empty groove 3022 for the function seat 302 to move upward when the box door 102 rotates. Thus, when the box door 102 rotates at this time, the box door 102 can drive the control gear 301 to rotate synchronously through the synchronous gear 2042. The cross-sectional shapes of the function seat 302 and the positioning disk 305 are both regular polygons, and a positioning groove 1011 is provided inside the box body 101. The function seat 302 and the positioning disk 305 are respectively inserted at the bottom and top of the positioning groove 1011. Under the action of the positioning groove 1011, the function seat 302 can never rotate automatically. Thus, when the control gear 301 rotates, the teeth of the damping tooth ring 3011 can be mutually pressed against the inclined sides of the tooth grooves of the damping tooth groove 3021, and the function seat 302 will automatically compress the damping top spring 3051 upward to avoid the rotation of the control gear 301. When the distance of a tooth of the damping tooth ring 3011 is rotated, under the action of the damping top spring 3051, the damping tooth groove 3021 can be inserted outside the damping tooth ring 3011 again, thus completing the triggering of a single damping effect, that is, when the box door 102 continuously rotates, the damping effect will be continuously triggered. It is convenient to use, so that the box door 102 will not rotate freely under the action of a small external force during use, and the use is stable.

[0047] Among them, a damping top spring 3051 is provided at the bottom of the positioning disk 305, and both ends of the damping top spring 3051 are respectively abutted against the bottom of the positioning disk 305 and the top of the function seat 302. During use, the rotation resistance of the box door 102 in the damping mode can be adjusted through the adjusting screw 304. When the adjusting screw 304 is rotated, the adjusting screw 304 can drive the positioning disk 305 to move up and down inside the positioning groove 1011 through the thread of the rod body, thus changing the initial telescopic length of the damping top spring 3051, and thus changing the force required to compress the damping top spring 3051 when triggering the damping effect, that is, the damping force, and can adapt to the use requirements of different damping forces, and the adaptability is extremely strong.

[0048] Among them, a functional empty slot 3022 is provided inside the functional seat 302, and a switching disc 3031 is provided at the bottom of the rod body of the switching screw 303. The switching disc 3031 is inserted inside the functional empty slot 3022, and the height of the slot body of the functional empty slot 3022 is greater than the sum of the thicknesses of the damping tooth ring 3011 and the switching disc 3031. During use, when the switching disc 3031 is located at the bottom of the functional empty slot 3022, the cabinet door 102 is in the adaptive locking mode at this time. Since the switching disc 3031 is located at the bottom of the functional empty slot 3022, the functional seat 302 cannot move upward, so that the damping tooth groove 3021 is always inserted outside the damping tooth ring 3011, making the control gear 301 locked and unable to rotate. At this time, the cabinet door 102 can only rotate after unlocking the door lock assembly 2, and the cabinet door 102 can be automatically locked at the use angle and position after the door lock assembly 2 is reset. When the door lock assembly 2 is in the reset state, the control gear 301 can prevent the cabinet door 102 from rotating freely through the synchronous gear 2042. When the door lock assembly 2 is unlocked, the synchronous gear 2042 can lose the tooth engagement relationship with the control gear 301, so that the cabinet door 102 can rotate freely, which can realize the real-time locking and regulation of the cabinet door 102. And when the switching screw 303 is continuously rotated to drive the switching disc 3031 to continuously move upward, the switching disc 3031 can abut against the top of the functional empty slot 3022 to drive the functional seat 302 to move upward synchronously, so that the damping tooth groove 3021 is always disengaged from the outside of the damping tooth ring 3011. After that, the cabinet door 102 is in the free mode. In this mode, the control gear 301 can rotate freely, so that the cabinet door 102 can also rotate freely, further improving the adaptability and flexibility of the device.

[0049] Specific usage method and function of this embodiment: In the present invention, the door lock assembly 2 can realize the locking and unlocking control of the box door 102. When the door lock assembly 2 is in the reset state, under the action of the locking top spring 2043, one end of the lock tongue rod 201 extends out of the box door 102, so that the lock tongue rod 201 can be inserted into the lock hole of the box body 101, thereby realizing the closing and locking use of the distribution box 1. When it is necessary to open the box door 102, only need to rotate the unlocking handle 202. When the unlocking handle 202 rotates, the unlocking gear 2021 can drive the lock tongue rod 201 to move to one side, so that the lock tongue rod 201 disengages from the inside of the lock hole. And when the unlocking gear 2021 rotates, it can drive the control rod 203 to move synchronously and in the opposite direction to the lock tongue rod 201 through the synchronous rack 2031. When the control rod 203 moves, the linkage rod 2032 can drive the control seat 204 to move downward synchronously through the linkage groove 2041 and compress the locking top spring 2043, thereby releasing the tooth engagement relationship between the synchronous gear 2042 and the control gear 301. After that, the box door 102 can be freely rotated and opened. The functional component 3 enables the box door 102 to have three usage modes: free mode, damping mode, and adaptive locking mode. The three usage modes can be freely adjusted and switched according to actual usage requirements. Since the teeth of the control gear 301 and the synchronous gear 2042 are engaged with each other when the door lock assembly 2 is in the reset state, the switching and use between the three usage modes of the box door 102 can be realized by controlling and adjusting the usage and movement state of the control gear 301. That is, when the adjusting screw 304 is fixed and the switching screw 303 is rotated alone, the switching screw 303 can move up and down inside the adjusting screw 304 through the rod thread to change the usage position of the switching disk 3031, thereby realizing the switching use of the three usage modes of the box door 102. When the switching disk 3031 is located at the top of the functional empty slot 3022, the box door 102 is in the damping mode at this time. That is, when the box door 102 is opened and the door lock assembly 2 is in the reset state, there is a certain damping force when the box door 102 rotates. In this mode, under the action of the damping top spring 3051, the damping tooth groove 3021 is inserted outside the damping tooth ring 3011, and there is enough space at the bottom of the functional empty slot 3022 for the functional seat 302 to move upward when the box door 102 rotates. Therefore, when the box door 102 rotates at this time, the box door 102 can drive the control gear 301 to rotate synchronously through the synchronous gear 2042. Under the action of the positioning groove 1011, the functional seat 302 cannot rotate automatically. Therefore, when the control gear 301 rotates, the teeth of the damping tooth ring 3011 can be squeezed against the tooth groove hypotenuse of the damping tooth groove 3021, and the functional seat 302 will automatically compress the damping top spring 3051 upward to avoid the rotation of the control gear 301. When the distance of one tooth of the damping tooth ring 3011 is rotated, under the action of the damping top spring 3051, the damping tooth groove 3021 can be inserted outside the damping tooth ring 3011 again, thereby completing the triggering of a single damping effect.That is, when the cabinet door 102 rotates continuously, the damping effect will be continuously triggered, which is convenient to use, so that the cabinet door 102 will not rotate freely under the action of a small external force during use. The rotational resistance of the cabinet door 102 in the damping mode can be adjusted by adjusting the screw 304. When the adjusting screw 304 is rotated, the adjusting screw 304 can drive the positioning disk 305 to move up and down inside the positioning groove 1011 through the rod thread, thereby changing the initial telescopic length of the damping top spring 3051, and thus changing the force required to compress the damping top spring 3051 when triggering the damping effect, that is, the damping force, which can meet the usage requirements of different damping forces. When the switching disk 3031 is located at the bottom of the function empty slot 3022, the cabinet door 102 is in the adaptive locking mode at this time. Since the switching disk 3031 is located at the bottom of the function empty slot 3022, the function seat 302 cannot move upward, so that the damping tooth groove 3021 is always inserted outside the damping tooth ring 3011, making the control gear 301 locked and unable to rotate. At this time, the cabinet door 102 can only rotate after unlocking the door lock assembly 2, and the cabinet door 102 can be automatically locked at the usage angle and position after the door lock assembly 2 is reset. When the door lock assembly 2 is in the reset state, the control gear 301 can prevent the cabinet door 102 from rotating freely through the synchronous gear 2042. When the door lock assembly 2 is unlocked, the synchronous gear 2042 can lose the tooth engagement relationship with the control gear 301, so that the cabinet door 102 can rotate freely, which can realize the real-time locking and regulation of the cabinet door 102. When the switching screw 303 is continuously rotated to drive the switching disk 3031 to move upward continuously, the switching disk 3031 can abut against the top of the function empty slot 3022 to drive the function seat 302 to move upward synchronously, so that the damping tooth groove 3021 is always disengaged from the outside of the damping tooth ring 3011. Thereafter, the cabinet door 102 is in the free mode. In this mode, the control gear 301 can rotate freely, and thus the cabinet door 102 can also rotate freely.,
