[0026] Example
[0027] like Figures 1 to 6 As shown, the utility model proposes a metering box that is easy to maintain, including a first box body 1, a second box body 2, a first box door 11 and a second box door 21, the first box body 1 and the first box door 11 and the second box body 2 and the second box door 21 are connected by a hinge, and also includes: a block 121 installed on the inner wall of the first box body 1 and the second box body 2, the interior of the block 121 is provided with a spring rod mechanism that automatically pops open the first box door 11 and the second box door 21, so that the first box door 11 and the second box door 21 can automatically pop open by pressing, which is simple and intuitive to operate, reducing the difficulty of operation for the user, especially when the hands are inconvenient or busy. At the same time, the automatic pop-up mechanism can speed up the opening of the first box door 11 and the second box door 21, making maintenance and inspection work more efficient, thereby shortening the time of the entire workflow. In addition, the operator does not need to manually pull open the first box door 11 and the second box door 21 with great effort, which significantly reduces physical exertion and is suitable for long-term maintenance work; a positioning mechanism is provided in the block 121 to fix the spring rod mechanism in a specified position.
[0028] Furthermore, the spring rod mechanism includes a telescopic push rod 122 that is slidably connected to the stop block 121. The end of the telescopic push rod 122 that is close to the rubber stop block 123 is provided with a marking line 124. The marking line 124 is the state that allows the telescopic push rod 122 to slide into the stop block 121, at which time the guide plug 35 of the sliding rod 31 is inserted into the slot 127. The end of the telescopic push rod 122 that is released from the stop block 121 is fixedly connected to the rubber stop block 123 that abuts the first and second doors 11, 21. The function of the rubber stop block 123 is to make the stop block 121 instantly abut the first and second doors 11, 21 without causing deformation or damage to the first and second doors 11, 21. The outer wall of the end of the telescopic push rod 122 that is inserted into the stop block 121 is fixedly connected to a support block 125. The interior of the stop block 121 is provided with a pull spring 126. The pull spring 126 causes the stop block 121 to generate a large thrust, thereby automatically opening the first and second doors 11, 21. One end of the pulling spring 126 is fixedly connected to the inner wall of the stop block 121 , and the other end of the pulling spring 126 is fixedly connected to the support block 125 .
[0029] Among them, the positioning mechanism includes a U-shaped frame 3 fixedly connected to the block 121, a pair of limiting slide grooves 33 are opened inside the U-shaped frame 3, and balls 36 are movably provided at both ends of the push plate 32 for sliding in the limiting slide grooves 33. A sliding rod 31 is slidably connected to the U-shaped frame 3, and a slot 127 is opened at one end of the telescopic rod 122 inserted into the block 121 for inserting one end of the sliding rod 31. The U-shaped frame 3 is slidably connected to the push plate 32 fixedly connected to the other end of the sliding rod 31. A push spring 34 is provided inside. The push spring 34 is used to automatically insert the guide plug 35 at the end of the sliding plug rod 31 into the slot 127. The elastic force of the push spring 34 is not as strong as the elastic force of the pull spring 126. Its function is to prevent the telescopic rod 122 from being restrained. The elastic tension of the pull spring 126 will prevent the guide plug 35 from being stuck in the slot 127. Only when the telescopic rod 122 slides just enough for the guide plug 35 to be stuck in the slot 127 can the telescopic rod 122 be stuck. One end of the push spring 34 is fixedly connected to the inner wall of the block 121, and the other end of the push spring 34 is fixedly connected to the push plate 32.
[0030] Furthermore, the end of the sliding rod 31 that is inserted into the slot 127 is provided with a guide plug 35 that allows the telescopic rod 122 to be removed by pressing firmly. The guide plug 35 makes it quick and easy to insert the end of the sliding rod 31 into the slot 127. The end of the telescopic rod 122 that is away from the rubber stop 123 is provided with a spherical stop 128 that abuts against the guide plug 35 and then pushes it toward the end of the U-shaped frame 3. The function of the spherical stop 128 is to automatically retract the sliding rod 31 into the U-shaped frame 3 after the guide plug 35 is abutted.
[0031] In this embodiment, when it is necessary to use a meter box that is easy to maintain, such as Figure 1 As shown, it is only necessary to press the first door 11 and the second door 21 firmly toward the first housing 1 and the second housing 2 to lock the telescopic rod 122. When the first door 11 and the second door 21 abut against the rubber stopper 123 at the end of the telescopic rod 122, the telescopic rod 122 drives the slot 127 to move, thereby causing the guide plug 35 at the end of the sliding rod 31 to disengage from the slot 127. Then, the pressed first door 11 or the second door 21 is released. The support block 125, through the elastic tension of the spring 126, causes the support block 125 to drive the telescopic rod 122 to quickly pass through the end of the sliding rod 31. At the same time, the telescopic rod 122 is also released toward the stopper 121. Finally, the telescopic rod 122 drives the rubber stopper 123 to instantly bounce to the first door 11 or the second door 21, thereby allowing the first door 11 and the second door 21 to open quickly, which is quick and easy to operate.
