Description
Technical Field
[0001] This utility model relates to the field of power equipment protection technology, and in particular to a structure for preventing the outer cover of a meter box from detaching. Background Technology
[0002] As a key facility in the power metering system, the meter box is widely used in residential communities, industrial and commercial parks and other scenarios. Its outer cover is an important component to ensure the safety of the internal meter and facilitate reading. It must balance protection and ease of operation.
[0003] Most existing meter box covers are mounted on the top or side of the box opening via hinges, pins, or other rotating mechanisms. The cover size is adapted to the opening, and the opening can be opened and closed by flipping it. To enhance protection, the cover is usually made of thin steel plate, engineering plastics, or similar materials. Some covers have flanges along their edges that mate with the box opening's edge; when closed, the flanges and edge prevent excessive flipping. When meter data needs to be read, the operator applies external force to flip the cover, exposing the internal meter. After reading the data, releasing the force allows the cover to close under its own weight or with a slight push.
[0004] However, the existing outer cover relies mainly on its own weight or the mechanical restraint of the flange and the edge to close, lacking a stable fastening structure. When subjected to external forces such as wind impact, the outer cover is prone to shaking or opening and closing, causing the rotating structure (such as hinge shaft and pin shaft) to be subjected to alternating loads continuously. After long-term use, the shaft will wear, the gap will increase, or even deform, which will cause the outer cover to jam when opening and closing. Utility Model Content
[0005] This application provides an anti-detachment structure for the outer cover of the meter box, which solves the technical problem in the prior art that the outer cover of the meter box is prone to shaking or opening and closing under the influence of wind and other factors, resulting in damage to the shaft and jamming during opening and closing.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a watch case outer cover anti-detachment structure, including a panel and a flip cover installed on the panel. The panel has an opening, and the two sides of the flip cover are rotatably installed on the top of the opening. The bottom of the opening is provided with a lower stop strip that can abut against the lower edge of the flip cover. The lower stop strip is fixedly connected to the panel. The lower stop strip has a strip-shaped horizontal groove. A magnet and a pressure plate are installed in the horizontal groove, and the pressure plate in the horizontal groove is fixedly connected to the lower stop strip. The magnet in the horizontal groove is located between the pressure plate and the lower stop strip.
[0007] When using this invention, the operator flips the cover to open the opening to check the meter reading, then closes the cover. The lower edge of the cover abuts against the bottom stop bar at the bottom of the opening. At this time, the magnet in the horizontal slot will attract the lower edge of the cover. Due to the magnetic attraction, the cover can be stably fastened, effectively limiting the cover from shaking or opening and closing arbitrarily under the action of external forces such as wind. Therefore, it avoids the problem of shaft wear, increased gaps, or deformation caused by the shaking of the cover in the prior art, which causes the rotating structure (such as hinge shaft, pin shaft) to continuously bear alternating loads. This ensures the smooth opening and closing of the cover during long-term use and extends the service life of the meter box cover.
[0008] As a further improvement to the above solution, side baffles are provided on both sides of the opening to abut against the edges of the flip cover. The side baffles are fixed to the panel and have a strip-shaped vertical slot inside. A magnet and a pressure plate are installed in the vertical slot, and the pressure plate inside the vertical slot is fixedly connected to the side baffle. The magnet inside the vertical slot is located between the pressure plate and the side baffle. The side baffles can both abut against the edges of the flip cover to achieve mechanical limitation and form a magnetic attraction fixation with the side edges of the flip cover through the magnet inside the vertical slot. Thus, when the flip cover is closed, the attraction force on the flip cover acts simultaneously from the bottom and the sides, greatly reducing the probability of the flip cover shaking.
[0009] As a further improvement to the above solution, both the horizontal and vertical slots are provided with grooves. The shape and size of the grooves are adapted to the magnets. The magnets are located in the grooves, and the surface of the magnets is flush with the bottom surface of the horizontal or vertical slots. Therefore, the magnets will not protrude from the surface of the horizontal or vertical slots, ensuring that the pressure plate can be pressed stably and tightly onto the surface of the magnets, avoiding loosening due to uneven force on the pressure plate caused by uneven magnet installation.
[0010] As a further improvement to the above solution, threaded holes are provided at both ends of the horizontal and vertical slots. The pressure plate is a strip-shaped plate with through holes at both ends. Screws are installed through the through holes and engage with the threaded holes at both ends of the horizontal or vertical slots. The pressure plate is fixed by using a screw-threaded hole engagement structure. This connection method is detachable, so when the magnet weakens or is damaged due to long-term use, the pressure plate can be removed by disassembling the screws to replace or maintain the magnet.
[0011] As a further improvement to the above solution, the through holes at both ends of the pressure plate are countersunk holes, and the head of the screw is located inside the countersunk of the through hole; therefore, the screw head will not protrude from the surface of the pressure plate, avoiding collision or friction between its edge and the screw head when the flip cover is closed, ensuring the smoothness of the flip cover closing process, and preventing the flip cover from failing to fit tightly against the retaining strip due to mechanical interference.
[0012] As a further improvement to the above solution, multiple grooves are provided at intervals along the length of both the horizontal and vertical slots, and a magnet is installed in each groove; this can increase the total adsorption force on the edge of the flip cover and enhance the stability of the flip cover after it is closed.
[0013] As a further improvement to the above solution, the magnets in the lower baffle and the side baffle are evenly distributed; thus, when the flip cover is closed, the adsorption force on its edge can be evenly distributed along the length direction of the lower baffle and the side baffle, avoiding deformation caused by uneven force on the edge of the flip cover due to excessive local adsorption force, or loosening gaps due to insufficient local adsorption force, ensuring that the flip cover and the baffle are tightly fitted.
[0014] As a further improvement to the above solution, the edge of the flip cover is provided with a strip-shaped iron sheet, which can be attracted to the magnets on the lower and side rails; thus, when the flip cover is closed, a stable attraction force can be generated between the iron sheet and the magnets, and the flip cover is firmly fixed in the closed position through magnetic attraction, thereby enhancing the anti-slip effect.
[0015] As can be seen from the above technical solutions, this utility model has at least the following technical effects or advantages: In use, the operator flips the cover to open the opening and check the meter reading, then closes the cover. The lower edge of the cover abuts against the bottom stop strip at the bottom of the opening. At this time, the magnet in the horizontal slot attracts the lower edge of the cover. The magnetic attraction provides a stable and secure hold, effectively preventing the cover from wobbling or opening and closing arbitrarily under external forces such as wind. This avoids the problems of shaft wear, increased gaps, or deformation caused by the rotating structure (such as hinge shafts and pins) being subjected to alternating loads due to cover wobbling in existing technologies. This ensures smooth opening and closing of the cover during long-term use and extends the service life of the meter box cover. Because the horizontal and vertical slots have grooves that fit the magnets, and the surface of the magnet is flush with the bottom surface of the horizontal or vertical slot after installation, the pressure plate can be stably and tightly pressed against the magnet surface, preventing loosening due to uneven force on the pressure plate caused by uneven magnet installation. Because the through holes at both ends of the pressure plate are countersunk holes, and the screw head is located inside the countersunk hole, the screw head will not protrude from the surface of the pressure plate. This avoids the edge of the flip cover colliding or rubbing against the screw head when the flip cover is closed, ensuring the smoothness of the flip cover closing process and preventing the flip cover from failing to fit tightly against the retaining strip due to mechanical interference.

Detailed Implementation To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, other embodiments obtained by those skilled in the art without creative effort are all within the scope of protection of this patent.
[0018] This utility model discloses an anti-detachment structure for the outer cover of the watch case, such as Figures 1 to 3 As shown, it includes a panel 2 and a flip cover 1 mounted on the panel 2. The panel 2 has an opening 201. The two sides of the flip cover 1 are rotatably mounted on the top of the opening 201. The bottom of the opening 201 has a lower stop strip 202 that can abut against the lower edge of the flip cover 1. The lower stop strip 202 is fixed to the panel 2. A magnet 4 and a pressure plate 5 are installed inside the lower stop strip 202. The pressure plate 5 presses against the surface of the magnet 4 and is fixedly connected to the lower stop strip 202.
[0019] In this embodiment, as Figure 1As shown, panel 2 is a flat plate structure, which is used to cover the electricity meter and other components inside the meter box. The opening 201 is rectangular, and the flip cover 1 is a rectangular plate that matches the opening 201. The upper edges of both sides of the flip cover 1 are rotatably mounted on the top sides of the opening 201 by hinges or pins, so that the flip cover 1 can be flipped relative to panel 2 around the rotation axis to open or close the opening 201. When the operator opens the opening 201, he can view the reading of the electricity meter inside the meter box. The lower stop bar 202 is a long strip structure, horizontally set along the bottom edge of the opening 201, and the edge of the lower stop bar 202 is fixed to the panel 2 by welding. A strip-shaped transverse slot 31 is opened on the side of the lower stop bar 202 facing the flip cover 1. The transverse slot 31 extends along the length of the lower stop bar 202. The magnet 4 is a permanent magnet, fitted and installed within the transverse slot 31. The pressure plate 5 is a strip-shaped metal plate matching the transverse slot 31, covering the surface of the magnet 4, and is fixed to the lower stop bar 202, pressing the magnet 4 tightly within the transverse slot 31. When the flip cover 1 is closed, the lower edge of the flip cover 1 abuts against the lower stop bar 202, and the lower edge of the flip cover 1 can be attracted by the magnet 4, preventing the flip cover 1 from flipping arbitrarily.
[0020] Specifically in this embodiment, such as Figure 1 As shown, a side baffle 203 is provided on each of the left and right edges of the opening 201. The side baffle 203 is a long strip structure, vertically arranged along the side of the opening 201, and the edge of the side baffle 203 is welded and fixedly connected to the panel 2. A strip-shaped vertical slot 32 is opened on the side of the side baffle 203 facing the flip cover 1. A magnet 4 is also installed in the vertical slot 32 and is pressed and fixed by a pressure plate 5. The fixing method of the pressure plate 5 is the same as that of the pressure plate 5 on the lower baffle 202. When the flip cover 1 is closed, its two sides abut against the side baffles 203 on both sides of the opening, and can be attracted to the magnets 4 in the side baffles 203, further enhancing the stability of the flip cover 1 after it is closed.
[0021] like Figure 2 , Figure 3 As shown, both the horizontal slot 31 and the vertical slot 32 have a groove 301 at the bottom. The shape and size of the groove 301 match the magnet 4, and its depth is equal to the thickness of the magnet 4. Thus, when the magnet 4 is embedded in the groove 301, the surface of the magnet 4 can be kept flush with the bottom surface of the horizontal slot 31 or the vertical slot 32, preventing the magnet 4 from protruding from the surface of the horizontal slot 31 or the vertical slot, thereby ensuring that the pressure plate 5 can be smoothly pressed onto the surface of the magnet 4.
[0022] Both ends of the horizontal slot 31 and the vertical slot 32 are provided with threaded holes 302, which are perpendicular to the bottom surface of the horizontal slot 31 or the vertical slot 32. The pressure plate 5 is a strip-shaped plate with through holes 501 at both ends corresponding to the positions of the threaded holes 302. The diameter of the through holes 501 is slightly larger than the diameter of the screw 6. During installation, the screw 6 passes through the through holes 501 and is threaded into the threaded holes 302, thereby fastening the pressure plate 5 to the horizontal slot 31 or the vertical slot 323 and pressing and fixing the magnet 4.
[0023] Specifically, the through hole 501 of the pressure plate 5 is a countersunk hole. The large diameter part of the countersunk hole faces the outside of the pressure plate 5. Its diameter is larger than the diameter of the screw head 6, and its depth is equal to the thickness of the screw head 6. When the screw 6 is installed, its head is completely contained in the countersunk hole, which can prevent the screw head 6 from protruding from the surface of the pressure plate 5 and prevent the flip cover 1 from colliding with the screw head 6 when it is closed.
[0024] More specifically, the lower baffle 202 has multiple grooves 301 spaced along its length in the horizontal slot 31, and each groove 301 contains a magnet 4; similarly, the side baffle 203 has multiple grooves 301 spaced along its length in the vertical slot 32, and each groove 301 also contains a magnet 4. The multiple magnets 4 enhance the attraction force on the flip cover 1. The spacing between the magnets 4 in the lower baffle 202 and the side baffle 203 is also equal, ensuring a uniform distribution of the attraction force when the flip cover 1 is closed, preventing tilting or loosening due to uneven attraction.
[0025] In addition, such as Figure 1 As shown, strip-shaped iron pieces 7 are fixed to the lower edge and both sides of the flip cover 1. The iron pieces 7 are fixed to the inner side of the edge of the flip cover 1 by screws or welding, and their length matches the length of the lower stop bar 202 and the side stop bar 203. When the flip cover 1 is closed, the iron pieces 7 are attracted to the magnets 4 on the lower stop bar 202 and the side stop bar 203, and the attraction force between the magnets 4 and the iron pieces 7 is used to enhance the fixing effect of the flip cover 1.
[0026] In actual use, when it is necessary to close the flip cover 1, flip the flip cover 1 downward around the top rotation axis until the lower edge of the flip cover 1 abuts against the lower stop strip 202 and the two side edges abut against the side stop strip 203. At this time, the iron piece 7 on the edge of the flip cover 1 is attracted to the magnet 4 in the lower stop strip 202 and the side stop strip 203. The magnetic attraction force fixes the flip cover 1 in the closed state, preventing external forces such as wind from causing the flip cover 1 to flip randomly. When it is necessary to open the flip cover 1, apply external force to overcome the magnetic attraction force and flip the flip cover 1 upward.
[0027] In the above structure, the magnets 4 inside the lower stop bar 202 and the side stop bar 203 attract the iron piece 7 on the edge of the flip cover 1, which can effectively limit the random rotation of the flip cover 1 and avoid damage to the shaft and detachment of the outer cover due to long-term shaking; multiple equally spaced magnets 4 can provide uniform and stable attraction force to ensure the stability of the flip cover 1 after it is closed; the cooperation between the pressure plate 5 and the screw 6 can firmly fix the magnets 4 and prevent the magnets 4 from loosening or falling off; the countersunk hole design can avoid the screw head interfering with the rotation of the flip cover 1. The overall structure is simple, easy to install, and can effectively improve the service life of the watch case outer cover.
