Description

Technical Field

[0001] The utility model relates to the technical field of power distribution boxes, in particular to a power distribution box. Background Art

[0002] Distribution boxes are electrical equipment characterized by their small size, ease of installation, exceptional technical performance, fixed location, unique configuration features, and unrestricted site availability. They are widely used, offer stable and reliable operation, high space utilization, minimal footprint, and are environmentally friendly. The numerous parameters associated with distribution boxes generally constitute a low-voltage distribution box. According to electrical wiring requirements, these boxes require the assembly of switchgear, measuring instruments, protective devices, and auxiliary equipment within an enclosed or semi-enclosed metal cabinet or on a screen. During normal operation, they can connect and disconnect circuits using manual or automatic switches.

[0003] The electrical distribution boxes currently in use are all hung on the wall. Although they are sealed, there will be more or less dead mosquitoes inside them, which not only makes the distribution box untidy, but some mosquitoes can also easily cause malfunctions in the internal components of the distribution box.

[0004] Therefore, it is necessary to provide a new distribution box to solve the above technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a distribution box.

[0006] The power distribution box provided by the utility model comprises a box body, the box body is provided with a box cover for covering an installation chamber provided in the box body, and the box cover is embedded with curved transparent glass;

[0007] A U-shaped elastic air cushion is fixedly embedded on the lower surface of the box cover, and a number of evenly distributed one-way exhaust valves are provided on the inner wall of the U-shaped elastic air cushion. Elastic shrinkage air bags are provided on both sides of the box cover, and the elastic shrinkage air bags are connected to adjacent U-shaped elastic air cushions through one-way air guide valves respectively. The U-shaped elastic air cushions contain insect repellent.

[0008] Preferably, the bag surface of the elastic shrinkage airbag close to the box cover side frame is fixedly connected to the box cover, and the elastic restoring force of the U-shaped elastic air cushion is greater than the air blocking pressure of the one-way air guide valve.

[0009] Preferably, two sets of pressing components are provided in the box cover, each used for pressing the elastic shrinkage airbag.

[0010] Preferably, the pressing assembly includes an inner frame plate, which is fixedly mounted in the box cover, and the upper curved surface of the inner frame plate is fixedly engaged with the curved transparent glass. The inner frame plate is elastically connected to the abutment plate through multiple springs, and the abutment plate abuts against the outer bag wall of the corresponding elastic shrinkage airbag.

[0011] Preferably, a U-shaped rubber plate is fixedly embedded on the lower surface of the U-shaped elastic air cushion.

[0012] Preferably, a U-shaped groove is provided on the box body, and the U-shaped groove and the installation chamber form a stepped shape, and the U-shaped groove matches the U-shaped elastic air cushion at the bottom of the box body.

[0013] Preferably, a flat lock is fixedly embedded on the box cover, and a lock groove is provided at a position of the box body corresponding to the flat lock.

[0014] Compared with the related art, the distribution box provided by the utility model has the following beneficial effects:

[0015] 1. After the box cover is rotated and closed onto the box body, the U-shaped elastic air cushion is pressed into the U-shaped groove on the box body, thereby compressing the U-shaped elastic air cushion and causing the insect repellent gas inside to be discharged from the one-way exhaust valve. As a result, the insect repellent gas can be accumulated in the box body, effectively reducing the risk of insects and ants entering the distribution box. This not only improves the cleanliness of the distribution box, but also prevents mosquitoes and insects from entering the distribution box and causing malfunctions in internal components.

[0016] 2. In the present invention, when the box lid is opened to inspect and maintain the internal components, the gas in the box body is discharged. At this time, since the U-shaped elastic air cushion is no longer pressed and its own elastic recovery force is greater than the air blocking pressure of the one-way air guide valve, the gas in the elastic contraction airbag can flow into the U-shaped elastic air cushion through the one-way air guide valve, so that the U-shaped elastic air cushion naturally returns to its original expanded state. After the subsequent work is completed and the box lid is closed, the insect repellent gas in the U-shaped elastic air cushion is discharged into the box body again, thereby protecting the box body, so that the insect repellent gas in the box body can be automatically filled each time.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0023] See also Figures 1 to 3 An embodiment of the present invention provides a distribution box, which includes: a box body 1, a box cover 2, a U-shaped elastic air cushion 3 and an elastic shrinkage airbag 5.

[0024] In the embodiments of the present invention, please refer to Figure 1 、 Figure 2 and Figure 3 The box body 1 is equipped with a box cover 2 for covering the installation chamber 1a provided in the box body 1, and the box cover 2 is embedded with an arc-shaped transparent glass 2'. A U-shaped elastic air cushion 3 is fixedly embedded on the lower surface of the box cover 2, and a number of evenly distributed one-way exhaust valves 4 are provided on the inner wall of the U-shaped elastic air cushion 3. Elastic shrinkage air bags 5 are provided on both sides of the box cover 2, and the elastic shrinkage air bags 5 are respectively connected to the adjacent U-shaped elastic air cushions 3 through the one-way air guide valves 6. The U-shaped elastic air cushion 3 contains insect repellent, and the bag surface of the elastic shrinkage air bag 5 close to the side frame of the box cover 2 is fixedly connected to the box cover 2. The elastic recovery force of the U-shaped elastic air cushion 3 is greater than the air blocking pressure of the one-way air guide valve 6.

[0025] It should be noted that: after the box cover 2 is rotated so as to be closed on the box body 1, the U-shaped elastic air cushion 3 is pressed into the U-shaped groove 1b provided on the box body 1, thereby the U-shaped elastic air cushion 3 is compressed and the insect repellent gas inside is discharged from the one-way exhaust valve 4. Therefore, the insect repellent gas can be accumulated in the box body 1, effectively reducing the entry of insects and ants into the distribution box, which not only improves the cleanliness of the distribution box, but also avoids the problem of mosquitoes entering the distribution box and causing malfunction of internal components;

[0026] When the box cover 2 is opened to inspect or maintain the internal components, the gas in the box body 1 is discharged. At this time, since the U-shaped elastic air cushion 3 is no longer compressed and its own elastic restoring force is greater than the air blocking pressure of the one-way air guide valve 6, the gas in the elastic shrink airbag 5 can flow into the U-shaped elastic air cushion 3 through the one-way air guide valve 6, so that the U-shaped elastic air cushion 3 naturally returns to its original expanded state. After the subsequent work is completed and the box cover 2 is closed, the insect repellent gas in the U-shaped elastic air cushion 3 is discharged into the box body 1 again, thereby protecting the box body 1, so that the insect repellent gas in the box body 1 can be automatically filled each time;

[0027] In this embodiment, the insect repellent stored in the elastic shrinkage airbag 5 is a gas insecticide, which can be selected according to needs. Since the odor of the gas insecticide will weaken after a period of time after entering the box body 1, it will not cause any impact on the human body after the box cover 2 is opened.

[0028] Among them, a flat lock 9 is fixedly embedded on the box cover 2, and a lock groove 9' is provided on the box body 1 corresponding to the flat lock 9. A U-shaped groove 1b is provided on the box body 1, and the U-shaped groove 1b and the installation chamber 1a form a stepped shape. The U-shaped groove 1b matches the U-shaped elastic air cushion 3 at the bottom of the box body 1. The flat lock 9 facilitates the closing and locking of the box cover 2 on the box body 1, and the U-shaped groove 1b matches the U-shaped elastic air cushion 3, thereby improving the sealing of the box cover 2 and the box body 1.

[0029] In the embodiments of the present invention, please refer to Figure 1 and Figure 3 Two groups of pressing components 7 for pressing the elastic shrinkage airbag 5 are provided in the box cover 2. The pressing component 7 includes an inner frame plate 71. The inner frame plate 71 is fixedly mounted in the box cover 2, and the upper arc surface of the inner frame plate 71 is fixedly engaged with the arc-shaped transparent glass 2'. The inner frame plate 71 is elastically connected to the abutment plate 72 through multiple springs 73, and the abutment plate 72 is abutted against the outer bag wall of the corresponding elastic shrinkage airbag 5. The lower surface of the U-shaped elastic air cushion 3 is fixedly engaged with a U-shaped rubber plate 8.

[0030] It should be noted that after the gas in the elastic shrinkable airbag 5 is discharged into the U-shaped elastic air cushion 3, the abutment plate 72 compresses the elastic shrinkable airbag 5 under the action of the spring 73, so that the elastic shrinkable airbag 5 can enter the U-shaped elastic air cushion 3 more stably.

[0031] The working principle of the distribution box provided by the utility model is as follows:

[0032] After the box cover 2 is rotated and closed onto the box body 1, the U-shaped elastic air cushion 3 is pressed into the U-shaped groove 1b provided on the box body 1, thereby compressing the U-shaped elastic air cushion 3 and causing the insect repellent gas inside to be discharged from the one-way exhaust valve 4. As a result, the insect repellent gas can be accumulated in the box body 1, effectively reducing the entry of insects and ants into the distribution box, which not only improves the cleanliness of the distribution box, but also avoids the problem of mosquitoes entering the distribution box and causing malfunction of internal components;

[0033] When the box cover 2 is opened to inspect and maintain the internal components, the gas in the box body 1 is discharged. At this time, since the U-shaped elastic air cushion 3 is no longer compressed and its own elastic restoring force is greater than the air blocking pressure of the one-way air guide valve 6, the gas in the elastic contraction airbag 5 can flow into the U-shaped elastic air cushion 3 through the one-way air guide valve 6, so that the U-shaped elastic air cushion 3 naturally returns to its original expanded state. After the subsequent work is completed and the box cover 2 is closed, the insect repellent gas in the U-shaped elastic air cushion 3 is discharged into the box body 1 again, thereby protecting the box body 1, so that the insect repellent gas in the box body 1 can be automatically filled each time.

[0034] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
