Description

Technical Field

[0001] The utility model belongs to the technical field of electric meter boxes, in particular to an electric meter box with adjustable height. Background Art

[0002] Electricity meter boxes are widely used in power facilities. They can be fixed directly to a wall or mounted on a utility pole. They can accommodate electronic and mechanical meters of any specification, as well as leakage protectors, junction boxes, DZ47 leakage circuit breakers, or RCL fuses, and disconnect switches. The meter is isolated from the disconnect switch, allowing users to control the disconnect switch without exposing the wiring. They also feature anti-theft features.

[0003] Chinese patent publication number CN219917907U discloses a meter box with a lifting function, comprising a mounting plate, a meter box body, and a mounting frame. Slide slots are provided on both sides of the mounting frame, and sliding blocks are slidably connected within the two slide slots. The opposing surfaces of the two sliding blocks are fixedly connected to the sides of the meter box body. One of the sliding blocks passes through a retaining slot provided in the mounting frame and is threadedly connected to a threaded rod. One side of the mounting frame is fixedly connected to a fixed frame. The height of the meter box can be adjusted by rotating the second gear and the tooth chain drive, thereby rotating the threaded rod.

[0004] However, in this technology, in addition to the structure of the meter box itself, a relatively large mounting frame is also required. Moreover, when the height of the meter box does not need to be adjusted, the space occupied by the mounting frame is fixed, which results in a large amount of space waste and increases the user's usage cost. Therefore, this technology needs to be improved. Utility Model Content

[0005] The purpose of the utility model is to provide an electric meter box with adjustable height in order to solve the above-mentioned technical problems. The electric meter box can be adjusted in height by extending and storing a lifting structure, which is convenient for user operation. At the same time, when there is no need to operate the structure inside the electric meter box, the space occupied can be reduced.

[0040] Example 1

[0041] This embodiment provides an electric meter box with adjustable height, comprising: a mounting base 1, a movable base 2, an electric meter box body 3, a driving mechanism 4, a locking mechanism 5,

[0042] See also Figure 2 , the back of the mounting base 1 is provided with a plurality of mounting parts, which can be used to mount the mounting base 1 to a fixed object, where the fixed object can be understood as a fixed building such as a wall or a telephone pole;

[0043] See also Figure 1 The mounting base 1 is provided with a receiving groove 101, which penetrates one side wall of the mounting base 1. The movable base 2 is slidably connected to the receiving groove 101. The movable base 2 can extend out of the receiving groove 101 when moving relative to the mounting base 1, and retract into the receiving groove 101 so that the movable base 2 is received in the mounting base 1. The movable base 2 is provided with an electric meter box body 3. The electric meter box body 3 here refers to an electric meter box product sold on the market.

[0044] The driving mechanism 4 is used to drive the movable seat 2 to move relative to the mounting seat 1. Any structure in the prior art that can drive the movable seat 2 to move relative to the mounting seat 1 can be used as the driving mechanism 4 here.

[0045] The locking mechanism 5 is used to lock and unlock the movable seat 2. When the movable seat 2 is locked, it cannot move relative to the mounting seat 1. When the movable seat 2 is unlocked, it can move relative to the mounting seat 1.

[0046] In this embodiment, after the mounting base 1 is installed vertically in the moving direction of the movable base 2 at a suitable position, when there is no need to operate the structure inside the meter box body 3, the movable base 2 is stored in the mounting base 1, and the locking mechanism 5 locks the movable base 2. When it is necessary to operate the structure inside the meter box body 3, the locking mechanism 5 locks the movable base 2, and the driving mechanism 4 drives the movable base 2 to move vertically downward relative to the mounting base 1. During this process, the movable base 2 descends with the meter box body 3. When the movable base 2 moves to a suitable height, the locking mechanism 5 locks the movable base 2 again. At this time, the user can operate the structure inside the meter box body 3. After the operation is completed, the locking mechanism 5 unlocks the movable base 2, and the driving mechanism 4 drives the movable base 2 to move vertically upward relative to the mounting base 1. During this process, the movable base 2 rises with the meter box body 3. After the movable base 2 is stored in the mounting base 1, the locking mechanism 5 locks the movable base 2.

[0053] The gear 403 is rotatably connected to the driving slot 402 via a rotating shaft. The gear 403 is meshed with the transmission rack 401. When the gear 403 rotates, it drives the transmission rack 401 to move, thereby driving the movable seat 2 to slide relative to the mounting seat 1.

[0054] The power input member 6 is used to drive the gear 403 to rotate. In this embodiment, the power input member 6 applies a rotational force to the gear 403 and can be driven manually or electrically.

[0055] When the movable seat 2 is unlocked by the locking mechanism 5 , the power input member 6 drives the gear 403 to rotate, and the gear 403 drives the movable seat 2 to slide relative to the mounting seat 1 through the transmission rack 401 , thereby achieving height adjustment of the meter box body 3 .

[0056] Example 3

[0057] This embodiment provides an electric meter box with adjustable height. Based on the second embodiment, a structure of the power input member 6 is also disclosed.

[0058] In this embodiment, please refer to Figure 3 The power input member 6 includes an input wheel 601 and a transmission wheel group 602. The output end of the transmission wheel group 602 is connected to the gear 403, and the input end of the transmission wheel group 602 is connected to the input wheel 601.
