Description

Technical Field

[0001] The present invention relates to the technical field of distribution boxes, and particularly relates to a distribution box with strong sealing performance. Background Art

[0002] In environments such as factories and workshops, dust is everywhere. When dust enters the interior of the power distribution cabinet, it will contaminate electrical components and parts, causing electrical failures of the equipment. After water molecules in the air enter the power distribution cabinet, it will cause electrical components to rust, corrode, short-circuit and other phenomena. In order to ensure the normal operation of the power distribution cabinet, it is usually necessary to seal it.

[0003] However, for the existing distribution boxes currently, there are still the following three deficiencies in their use:

[0004] First, threading holes or threading pipes are provided at the rear of the distribution box, and the wires are clamped in the threading pipes. At this time, there is a gap between the wires and the threading pipes, which is likely to cause external dust or crawlers to enter the interior of the distribution box, thereby damaging the components inside the distribution box.

[0005] Second, when the worker closes the door panel of the distribution box, if the force is too large, the door panel will violently impact the box body, causing the distribution box to vibrate, which is likely to cause the parts inside the distribution box to become loose, and it will also cause the sealing performance between the door panel and the distribution box to deteriorate.

[0006] Third, the two upper corners of the distribution box are easily bumped by external objects, resulting in the paint spraying on the outside of the four corners of the distribution box falling off and rusting. At this time, the sealing performance of the distribution box will decrease, and external water vapor will enter the interior of the box body 1 from the rusted place, which is likely to damage the internal components of the distribution box. Summary of the Invention

[0007] In view of this, the present invention provides a distribution box with strong sealing performance to solve the problems of poor sealing performance of the distribution box, external dust or crawlers entering the interior of the distribution box through the threading pipe and damaging the components inside the distribution box, and the door panel hitting the box body when closing, causing the distribution box to vibrate and easily resulting in the loosening of the internal parts of the distribution box.

[0009] Further, the clamping mechanism includes: a clamping plate, the main body of the clamping plate is in an arc shape, a clamping nail is fixedly installed on the inner end surface of the clamping plate, and the clamping nail is in an inclined shape; a first spring, the first spring is fixedly installed on the outer end surface of the clamping plate, and the outer end surface of the first spring is fixedly connected to the inner wall of the wire passing pipe.

[0010] Further, a fastening plate is clamped inside the groove on the surface of the bottom plate of the box body, four connecting screw rods are fixedly installed on the lower end surface of the fastening plate, and the connecting screw rods are clamped in the fixing holes on the surface of the cushion block.

[0011] Further, two fixed ear plates are respectively installed at the left and right ends of the box body, and through holes are opened on the surfaces of the fixed ear plates.

[0012] Further, fixed clamping strips are fixedly installed on the inner wall surface of the box body, and when the door panel is in a closed state, the fixed clamping strips are clamped in the grooves on the outer end surface of the door panel.

[0017] The present invention provides a distribution box with strong sealing performance, and its beneficial effects are as follows:

[0018] In the present invention, when the door panel is closed, the fixed clamping strip is clamped in the groove, so that the door panel and the box body can be closely attached to each other, avoiding the appearance of gaps, thereby preventing external dust or other sundries from entering the box body, and improving the sealing performance of the distribution box.

[0019] In addition, two fixed ear plates are respectively installed at the left and right ends of the box body. When it is necessary to install the box body on the wall surface, the screw can pass through the through hole on the surface of the fixed ear plate to fix the box body on the wall. Four card slots are formed on the lower end surface of the box body. When it is necessary to install the box body on the ground, the fastening plate can be clamped in the card slot, and then the connecting screw rod can be clamped in the fixing hole on the surface of the cushion block. After the worker tightens the nut on the surface of the connecting screw rod, the box body can be fixed on the ground, thus facilitating the installation of the box body by the worker.

[0020] In addition, a brush is provided at the front end inside the wire pipe. The brush can fill the gap between the wire and the wire pipe, preventing external dust or mosquitoes from entering the box body through the wire pipe. The surface of the clamping plate is fixedly installed with inclined nails, and a first spring is provided between the clamping plate and the inner wall of the wire pipe. Under the action of the elastic force of the first spring, the nails can be in close contact with the wire, so that when the worker accidentally touches the wire, the nails can play a role in limiting and intercepting the wire, avoiding the loosening of the joint between the wire and the component.

[0021] In addition, a rotating shaft is rotatably connected to the middle of the observation glass. When the rotating shaft rotates, it can drive the cleaning plate to rotate. A cleaning cotton is clamped inside the fixing frame at the front end of the cleaning plate, so that the cleaning cotton can clean the inner end surface of the observation glass, thereby making the worker's vision clearer. The first connection groove inside the rotating shaft communicates with the second connection groove inside the cleaning plate. The worker can inject the cleaning liquid into the first connection groove, and then the cleaning liquid will pass through the second connection groove and enter the cleaning cotton through the spray pipe, which is convenient for the cleaning cotton to clean the observation glass.

[0022] In addition, a second magnet is installed at the front end of the fixing rod, and two first magnets are installed on the surface of the door panel. The outer poles of the first magnet and the second magnet are the same. When the worker closes the door panel and the door panel contacts the box body, according to the principle of like poles repelling each other, the rotation speed of the door panel can be reduced, so that the impact force of the door panel colliding with the box body is reduced. When the door panel closes slowly, it will not damage the parts inside the box body.

[0023] In addition, two protective plates are inserted outside the fixed bar, which plays a role in protecting the two upper corners of the box body to prevent the two corners from being knocked. A desiccant is filled in the placement groove inside the protective plate, and ventilation holes are evenly opened at the bottom end of the placement groove, so that the desiccant inside the placement groove can adsorb the water vapor at the two upper corners of the box body, ensuring that the two upper corners of the box body are always dry, thereby avoiding rust and improving the sealing performance of the box body.

[0056] Embodiment 2: The present invention provides a distribution box with strong sealing performance. On the basis of Embodiment 1, as Figures 1 - 9As shown in the figure, it further includes: a fastening plate 13 is clamped inside a slot 102 on the surface of the bottom plate of the box body 1. Four connecting screws 1301 are fixedly installed on the lower end surface of the fastening plate 13. The connecting screws 1301 are clamped in fixing holes 1401 on the surface of a cushion block 14. Two fixing ear plates 101 are respectively installed at the left and right ends of the box body 1, and through holes are formed on the surfaces of the fixing ear plates 101.

[0057] By adopting the above scheme, the technical effects are as follows: Two fixing ear plates 101 are respectively installed at the left and right ends of the box body 1. When it is necessary to install the box body 1 on the wall surface, screws can be passed through the through holes on the surfaces of the fixing ear plates 101 to fix the box body 1 on the wall. Four slots 102 are formed on the lower end surface of the box body 1. When it is necessary to install the box body 1 on the ground, the fastening plate 13 can be clamped in the slot 102, and then the connecting screws 1301 are clamped in the fixing holes 1401 on the surface of the cushion block 14. After the worker tightens the nuts on the surfaces of the connecting screws 1301, the box body 1 can be fixed on the ground, thus facilitating the installation of the box body 1 by the worker.

[0058] Embodiment 3: The present invention provides a distribution box with strong sealing performance. On the basis of Embodiment 1, as Figures 1 - 9 shown in the figure, it further includes: a second magnet 1201 is fixedly installed on the front end surface of a fixing rod 12. Two first magnets 201 are installed on the upper and lower inner end surfaces of a door panel 2. A second spring 11 is fixedly installed at the middle position of the rear end surface of a sliding plate 10. The rear end of the second spring 11 is fixedly connected to the rear wall of a device slot 901.

[0059] By adopting the above scheme, the technical effects are as follows: A second magnet 1201 is installed at the front end of the fixing rod 12, and two first magnets 201 are installed on the surface of the door panel 2. The outer poles of the first magnet 201 and the second magnet 1201 are the same. When the worker closes the door panel 2 and the door panel 2 contacts the box body 1, according to the principle of repulsion between like poles of magnets, the rotation speed of the door panel 2 can be reduced. At this time, the fixing rod 12 will move backward. When the sliding plate 10 moves backward, the second spring 11 will be compressed by force, so that part of the impact force of the door panel 2 can be converted into the elastic force of the second spring 11, thus reducing the impact force when the door panel 2 collides with the box body 1. When the door panel 2 is slowly closed, it will not damage the parts inside the box body 1.

[0060] Embodiment 4: The present invention provides a distribution box with strong sealing performance. On the basis of Embodiment 1, as Figures 10 - 11 shown in the figure: A slot 1503 is respectively formed on the inner end surfaces of the horizontal plate and the vertical plate of a protective plate 15. A fixed bar 105 on the outer end surface of the box body 1 is inserted into the slot 1503 on the inner end surface of the protective plate 15. A desiccant is filled in a placement groove 1501 inside the protective plate 15.

[0061] By adopting the above solution, the technical effects are as follows: The two corners at the upper end of the box body 1 are easily knocked by other objects, resulting in the paint spraying on the outside of the four corners falling off. Therefore, the two corners at the upper end of the box body 1 are very prone to rusting. The sealing performance of the box body 1 will be reduced, and the water vapor from the outside will enter the inside of the box body 1 from the rusty places. There is a fixed strip 105 outside the box body 1, and two slots 1503 are opened inside the protection plate 15. Workers can insert the two protection plates 15 outside the fixed strip 105, which plays a role in protecting the two corners at the upper end of the box body 1 and prevents the two corners from being knocked. There is also a placement groove 1501 opened inside the protection plate 15, and a desiccant is filled in the placement groove 1501. Ventilation holes 1502 are evenly opened at the bottom end of the placement groove 1501, so that the desiccant inside the placement groove 1501 can adsorb the water vapor at the positions of the two corners at the upper end of the box body 1, ensuring that the two corners at the upper end of the box body 1 are always in a dry state, thus avoiding rust and improving the sealing performance of the box body 1.

[0062] Specific usage and functions of this embodiment: In the present invention, two fixed ear plates 101 are respectively installed at the left and right ends of the box body 1. When it is necessary to install the box body 1 on the wall surface, screws can be passed through the through holes on the surface of the fixed ear plates 101 to fix the box body 1 on the wall. Four card slots 102 are provided on the lower end surface of the box body 1. When it is necessary to install the box body 1 on the ground, the fastening plate 13 can be snapped into the card slots 102, and then the connecting screw rod 1301 can be snapped into the fixing hole 1401 on the surface of the cushion block 14. After the worker tightens the nut on the surface of the connecting screw rod 1301, the box body 1 can be fixed on the ground, thus facilitating the installation of the box body 1 by the worker. Wires are snap-fitted inside the wire conduit 6, and a brush 601 is provided at the front end inside the wire conduit 6. The brush 601 can fill the gap between the wire and the wire conduit 6, preventing external dust, mosquitoes, etc. from entering the box body 1 through the wire conduit 6. An inclined staple 701 is fixedly installed on the surface of the clamping plate 7, and a first spring 8 is provided between the clamping plate 7 and the inner wall of the wire conduit 6. Under the action of the elastic force of the first spring 8, the staple 701 can be in close contact with the wire, so that when the worker accidentally touches the wire, the staple 701 can play a role in limiting and intercepting the wire, preventing the connection between the wire and the components from loosening. To ensure the safety of the components inside the box body 1, the door panel 2 and the box body 1 are closed with a lock. Through the setting of the observation glass 202 on the surface of the door panel 2, the worker can observe the situation inside the box body 1 through the observation glass 202. A rotating shaft 3 is rotatably connected in the middle of the observation glass 202. When the rotating shaft 3 rotates, it can drive the cleaning plate 4 to rotate. A cleaning cotton 5 is snap-fitted inside the fixing frame 401 at the front end of the cleaning plate 4, and the cleaning cotton 5 is in contact with the observation glass 202, so that the cleaning cotton 5 can clean the inner end surface of the observation glass 202, thereby making the worker's vision clearer. The first connection groove 301 inside the rotating shaft 3 communicates with the second connection groove 402 inside the cleaning plate 4. The worker can inject the cleaning liquid into the first connection groove 301, and then the cleaning liquid will pass through the second connection groove 402 and enter the cleaning cotton 5 through the spray pipe 403, facilitating the cleaning of the observation glass 202 by the cleaning cotton 5. A second magnet 1201 is installed at the front end of the fixed rod 12, and two first magnets 201 are installed on the surface of the door panel 2. The outer poles of the first magnet 201 and the second magnet 1201 are the same. When the worker closes the door panel 2 and the door panel 2 contacts the box body 1, according to the principle of like poles repelling each other of magnets, the rotation speed of the door panel 2 can be reduced. At this time, the fixed rod 12 will move backward. When the sliding plate 10 moves backward, the second spring 11 will be compressed by force, thereby converting part of the impact force of the door panel 2 into the elastic force of the second spring 11, thus reducing the collision force between the door panel 2 and the box body 1. When the door panel 2 closes slowly, it will not damage the parts inside the box body 1.
