Description

Technical Field

[0001] This utility model belongs to the field of metering box technology, and in particular relates to a waterproof device for metering box door panel. Background Technology

[0002] As a crucial metering device in power systems, the protective performance of metering boxes directly impacts the operational safety of their internal components. Outdoor metering boxes are exposed to complex environments for extended periods, and insufficient sealing of the door panels can easily lead to rainwater infiltration, causing problems such as short circuits and metering errors.

[0003] Current mainstream sealing solutions mostly employ rubber strip pressing structures. However, due to factors such as door panel deformation and aging, it is difficult to guarantee long-term effective sealing, allowing rainwater to seep in through the door gaps. Furthermore, these solutions rely on the door panel's own weight to tighten the sealing strip, making it impossible to dynamically adjust the tightening force according to the aging of the sealing strip, and they lack a multi-layered waterproof barrier design. Therefore, we provide a waterproof device for metering box door panels to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a waterproof device for metering box doors. By combining the internal support mechanism and the water-blocking mechanism, it solves the problems of non-adjustable sealing pressure and simple waterproof structure in existing metering box door waterproof devices.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0006] This utility model relates to a waterproof device for a metering box door panel, comprising a metering box body, to which a door body is hinged via a hinge on the front side; an inner support mechanism is provided on the inner side of the door body, the inner support mechanism including a rotating shaft movably connected to the inner wall of the door body via a bearing seat, a cam fixedly connected to the surface of the rotating shaft, a first inner support plate provided on one side of the door body, and second inner support plates provided on both sides of the first inner support plate; a water-blocking mechanism is provided on the inner side of the metering box body, the water-blocking mechanism including a baffle fixedly connected to the inner side of the metering box body, and a waterproof strip fixedly connected to one side of the baffle.

[0007] The present invention is further configured such that one end of the rotating shaft extends through to the outside of the box door body and is fixedly connected to a handle, and an indicator line is provided on the back of the box door body. The pressure can be quantitatively adjusted by aligning the rotation angle of the handle with the indicator line, and the optimal sealing state is achieved when the indicator line is aligned with the edge of the box body.

[0008] The present invention is further configured such that a drive rod is fixedly connected to one side of the first inner support plate, and a push plate is fixedly connected to the other end of the drive rod. One side of the push plate contacts the surface of the cam but is not fixedly connected. When the cam rotates, it pushes the push plate to move linearly, converting the rotational motion into linear displacement and improving the transmission efficiency.

[0009] The present invention is further configured such that a telescopic rod is fixedly connected to one side of both the first inner support plate and the second inner support plate, and a mounting plate is fixedly connected to the other end of the telescopic rod. One side of the mounting plate is fixedly connected to one side of the door body.

[0010] The present invention is further configured such that a spring is sleeved on the surface of the telescopic rod, and there are four sets of telescopic rods and the mounting plate, with two in each set. The four sets of telescopic rods are arranged in a rectangular pattern. The spring provides a rebound force when the handle is released, ensuring that the first inner support plate and the second inner support plate quickly return to their original positions.

[0011] The present invention is further configured such that a drive wheel is fixedly connected to one side of the first inner support plate, and a drive block is fixedly connected to one side of the second inner support plate. The drive wheel contacts the inclined surface of the wedge-shaped drive block on one side of the second inner support plate. The movement of the first inner support plate can drive the two second inner support plates on both sides to expand outward synchronously, thereby achieving balanced pressure in four directions.

[0012] The present invention is further configured such that the waterproof strip is frame-shaped, the waterproof strip is formed by dispensing adhesive in one step, the waterproof strip is formed by dispensing liquid silicone, and forms a labyrinth-like sealing structure with the baffle. The frame-shaped structure makes the door frame evenly pressurized around its perimeter, resulting in higher sealing performance compared to traditional strip-shaped seals.

[0013] The present invention has the following beneficial effects.

[0014] 1. This utility model uses a cam to drive the first inner support plate to move linearly, and with the inclined transmission of the drive wheel and the wedge-shaped drive block, it realizes the synchronous outward expansion movement of the second inner support plates on both sides, forming a four-way balanced pressure, ensuring that the waterproof strip is evenly squeezed around the door frame, eliminating single-point stress concentration, significantly improving the sealing surface fit, and the parallelogram support structure composed of the telescopic rod and the spring automatically compensates for the assembly tolerance between the box and the door panel when the door panel is closed. At the same time, it can buffer the deformation caused by thermal expansion and contraction, maintain a constant clamping force, and extend the service life of the sealing components.

[0015] 2. This utility model forms a stepped sealing structure through the baffle and the waterproof strip. The baffle acts as the first line of defense to block most of the water flow. The frame-shaped waterproof strip, which is formed by dot-gluing, fits tightly with the door panel after being pressed, forming a second labyrinth seal. The double protection results in a high waterproof rating.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Please see Figures 1-5 This utility model is a waterproof device for a metering box door panel, including a metering box body 1, and a door body 2 hinged to the front of the metering box body 1; an inner support mechanism is provided on the inner side of the door body 2, the inner support mechanism includes a rotating shaft 3 movably connected to the inner wall of the door body 2 through a bearing seat, a cam 4 fixedly connected to the surface of the rotating shaft 3, a first inner support plate 5 provided on one side of the door body 2, and second inner support plates 6 provided on both sides of the first inner support plate 5; a water blocking mechanism is provided on the inner side of the metering box body 1, the water blocking mechanism includes a baffle 7 fixedly connected to the inner side of the metering box body 1, and a waterproof strip 8 fixedly connected to one side of the baffle 7.

[0027] Further details: The handle 9, fixedly connected to the end of the rotating shaft 3, is used for rotation control. The cam 4 rotates with the rotating shaft 3 and generates eccentric motion. The first inner support plate 5 is connected to the push plate 12 through the drive rod 11. The push plate 12 contacts the surface of the cam 4. The second inner support plate 6 is symmetrically distributed on both sides of the first inner support plate 5. The linkage is achieved through the cooperation of the drive wheel 16 and the inclined surface of the drive block 17. The baffle 7 integrally formed on the inner wall of the box and the frame-shaped waterproof strip 8 formed by dotting adhesive form a double-layer waterproof barrier. The four sets of telescopic rods 13, together with the springs 15, form a parallelogram support structure. The mounting plate 14 is fixed to the inside of the box door to ensure the directional movement and automatic reset of the inner support plate.

[0028] Example 2

[0029] Please see Figures 1-5 Based on embodiment 1, one end of the rotating shaft 3 extends through to the outside of the door body 2 and is fixedly connected to a handle 9. An indicator line 10 is provided on the back of the door body 2. A drive rod 11 is fixedly connected to one side of the first inner support plate 5, and a push plate 12 is fixedly connected to the other end of the drive rod 11. One side of the push plate 12 contacts the surface of the cam 4 but is not fixedly connected. Telescopic rods 13 are fixedly connected to one side of both the first inner support plate 5 and the second inner support plate 6. A mounting plate 14 is fixedly connected to the other end of the telescopic rod 13. One side of the mounting plate 14 is fixedly connected to one side of the door body 2. A spring 15 is sleeved on the surface of the telescopic rod 13. There are four sets of telescopic rods 13 and mounting plates 14, with two in each set. A drive wheel 16 is fixedly connected to one side of the first inner support plate 5, and a drive block 17 is fixedly connected to one side of the second inner support plate 6. The waterproof strip 8 is frame-shaped and is formed by dotting adhesive in one piece.

[0030] Further details: The pressure can be quantitatively adjusted by aligning the rotation angle of the handle 9 with the indicator line 10. The optimal sealing state is achieved when the indicator line 10 is aligned with the edge of the box. When the cam 4 rotates, it pushes the push plate 12 to move linearly, converting the rotational motion into linear displacement and improving transmission efficiency. The four sets of telescopic rods 13 are distributed in a rectangular shape. The spring 15 provides a rebound force when the handle 9 is released, ensuring that the first inner support plate 5 and the second inner support plate 6 are quickly reset. The drive wheel 16 contacts the inclined surface of the wedge-shaped drive block 17 on one side of the second inner support plate 6. The movement of the first inner support plate 5 can drive the second inner support plates 6 on both sides to expand outward synchronously, achieving balanced pressure in four directions. The waterproof strip 8 is made of liquid silicone adhesive and forms a labyrinth-like sealing structure with the baffle 7. The frame structure makes the door frame evenly pressurized around, resulting in higher sealing performance compared to traditional strip-shaped seals.

[0031] The working principle of this utility model is as follows: When closing the door, rotating the handle 9 clockwise aligns the indicator line 10 with the box body. The rotating shaft 3 drives the cam 4 to rotate, pushing the push plate 12 and the drive rod 11 to move the first inner support plate 5 outward. The drive wheel 16 contacts the inclined surface of the drive block 17, driving the second inner support plates 6 on both sides to expand outward simultaneously. The four inner support plates together compress the waterproof strip 8 to produce deformation and seal. The baffle 7 forms the first waterproof barrier, forming a double seal with the pressure-expanded waterproof strip 8. When opening, rotating the handle 9 in the opposite direction releases the stored energy of the spring 15, causing the inner support plates to return to their original position, facilitating door opening.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
