In one preferred embodiment of the present application, as shown in fig. 1 to 11, a waterproof and electric shock-proof switch box includes a switch box body 1, a pulling plate 2 and a protective member 3. The switch box body 1 is fixedly arranged on a wall body, a plug for plugging an electric appliance is arranged on the switch box body 1, and meanwhile, a containing cavity 100 is formed in the side part of the switch box body 1; the pulling plate 2 is slidably arranged on the side part of the switch box body 1, so that the pulling plate 2 can be matched with the containing cavity 100; the shielding member 3 is mounted to the back of the pulling plate 2. When the plug is plugged with an electric appliance for use, the pulling plate 2 can store the protective component 3 in the storage cavity 100 and limit the protective component; when the plug is not used, the pulling plate 2 can release the limitation on the protective component 3, so that the protective component 3 can move towards the plug, and the port of the plug is locked and sealed. At the moment, the switch box enters a protection state, the port of the plug is sealed through the protection component 3, and water can not enter the port of the plug, so that a waterproof effect is achieved; meanwhile, the protection component 3 is locked, so that children can be prevented from opening the protection component 3, and the electric shock prevention effect is achieved.

In this embodiment, the number of the shielding members 3 and the housing cavities 100 corresponds to each other, and there are various ways of disposing the shielding members 3 and the housing cavities 100, including but not limited to the following two.

The first method is as follows: one side of the switch box body 1 is provided with a containing cavity 100, the number of the protective components 3 is one, and when the plug is used, the protective components 3 are contained in the containing cavity 100. When the plug is not used, the protection component 3 can move along the containing cavity 100 to the other side of the switch box body 1, and then the port of the plug can be locked and sealed.

The second method comprises the following steps: as shown in fig. 1 to 3 and 8 to 10, the switch box body 1 is provided with two receiving cavities 100 on a pair of opposite sides, so that the number of the shielding members 3 is two, and when the plug is used, the two shielding members 3 are received in the two receiving cavities 100. When the plug is not in use; the protective components 3 in the two accommodating cavities 100 can move in opposite directions until being in butt fit, and then the ports of the plug can be locked and sealed.

It is understood that the specific arrangement can be selected by those skilled in the art according to actual needs. For convenience of description, the following description will be given with a structure of the mode two.

In one embodiment of the present application, as shown in fig. 1, 8 to 10, when the plug is used, the pulling plate 2 may cause the shielding member 3 to be received and limited in the receiving cavity 100 by pressing the shielding member 3. When the plug is not used, the pull plate 2 can be pulled, so that a movable gap with a distance X can be generated between the pull plate 2 and the switch box body 1; the limitation on the protective component 3 can be removed through the generated movable gap, so that the protective component 3 can slide along the movable gap, and the shielding of the plug port is realized; and after the port of the plug is shielded by the protective component 3, the pulling plate 2 can press the protective component 3 again to ensure that the protective component 3 and the port of the plug are in sealed sealing fit, so as to ensure the waterproofness of the protective component 3.

In this embodiment, the extrusion force generated by the pulling plate 2 on the protective component 3 can be realized through various structures. Including but not limited to the following two.

The structure I is as follows: the pulling plate 2 and the switch box body 1 are magnetically attracted. Thus, when the plug is used, the shield member 3 can be accommodated in the accommodation chamber 100 under the pressure of the magnetic attraction force generated between the pulling plate 2 and the switch case body 1. When the plug does not use, through pulling arm-tie 2 to produce the clearance between arm-tie 2 and the switch box body 1, and then protective part 3 slides along the clearance that produces, shelters from with the realization to the port of plug. Subsequently, the pulling plate 2 is loosened, and the protective component 3 is extruded again through the magnetic adsorption force generated between the pulling plate 2 and the switch box body 1, so that the protective component 3 can be tightly attached to the port of the plug, and the port of the plug is tightly sealed.

The structure II is as follows: the pulling plate 2 and the switch box body 1 are elastically connected. Thus, when the plug is used, the shield member 3 can be accommodated in the accommodation chamber 100 under the elastic force generated between the pulling plate 2 and the switch box body 1. When the plug does not use, through pulling arm-tie 2 to produce the free gap between arm-tie 2 and the switch box body 1, and then protective part 3 slides along the free gap that produces, shelters from with the realization to the port of plug. Subsequently, the pulling plate 2 is loosened, and the protective component 3 is extruded again through the elastic force generated between the pulling plate 2 and the switch box body 1, so that the protective component 3 can be tightly attached to the port of the plug, and the port of the plug is tightly sealed.

Specifically, as shown in fig. 2 and 7, the back of the pulling plate 2 and the switch box body 1 are connected by a first spring 400, and the first spring 400 is always in a stretching state, so that elastic force close to each other can be always generated between the pulling plate 2 and the switch box body 1 to press the shielding member 3.

In this embodiment, as shown in fig. 3, 4 and 7, the back of the pulling plate 2 is fixedly provided with a guide rod 22, and the switch box body 1 is provided with a guide groove 110 slidably engaged with the guide rod 22. Therefore, when the pulling plate 2 is pulled, the pulling plate 2 can slide along the guide groove 110 through the guide rod 22, and further, the pulling plate 2 can be prevented from being deviated in the pulling process, so that the movement of the shielding component 3 is interfered.

It will be appreciated that the pulling distance of the pulling plate 2 is less than the maximum sliding fit distance of the guide bar 22 and the guide slot 110. And when the above-mentioned structure two is adopted between the pulling plate 2 and the switch box body 1, the first spring 400 can be disposed in the guide groove 110, so that the installation of the first spring 400 can be facilitated.

In the present embodiment, as shown in fig. 1, 4, and 8 to 10, a handle portion 21 is provided on the front surface of the pulling plate 2, and the pulling of the pulling plate 2 can be facilitated by the handle portion 21.

In one embodiment of the present application, as shown in fig. 4 and 8 to 10, the pull plate 2 is provided with sliding grooves 200 at upper and lower ends of a back portion thereof, and the shielding member 3 is slidably mounted in the sliding grooves 200. When the pulling plate 2 is pulled, the protective component 3 can slide to the plug port position along the sliding groove 200, so that the port of the plug can be shielded and sealed.

It will be appreciated that the sliding of the shielding member 3 along the slide groove 200 can be driven manually or automatically by means of elastic force. For the convenience of the user, the elastic driving mode is preferably adopted in the application.

In the present embodiment, the shielding member 3 has various structures including, but not limited to, the following two.

The structure I is as follows: the protective part 3 comprises a protective plate 31, and the protective plate 31 is slidably arranged on the sliding chute 200; the side of the shielding plate 31 adjacent to the plug is connected to the side of the pulling plate 2 by a second spring 500. So that the shielding plate 31 can slide along the slide groove 200 by the elastic force of the second spring 500 when the pulling plate 2 is pulled, thereby allowing the port of the plug to be sealed.

It is understood that, when the pulling plate 2 is pulled, the movable gap X generated between the pulling plate 2 and the switch box body 1 has a value at least greater than the thickness t of the shielding plate 31. Generally, t is 0.5-2mm.

The structure II is as follows: as shown in fig. 2, 6, 8 to 10, the shield member 3 includes a plurality of shield plates 31 and a plurality of hinge rods 32. The protection plates 31 can be hinged through hinge rods 32 to form a protection plate group; the end part of the protection plate group far away from the plug is rotatably connected with the end part of the sliding groove 200 through the hinge rod 32, and the end part of the protection plate group close to the plug is in sliding fit with the sliding groove 200 through the hinge rod 32; meanwhile, the hinge rod 32 of the end of the guard plate group close to the plug is connected with the side of the pulling plate 2 through the second spring 500. When the plug is used, the protection plate group can be folded and stored in the storage cavity 100; when the plug is not used, the pulling plate 2 is pulled, and the protection plate group can slide along the sliding groove 200 under the elastic force of the second spring 500 and expand, so that the port of the plug can be sealed.

It will be appreciated that when the pull plate 2 is pulled, the amount of clearance X created between the pull plate 2 and the switch box body 1 is at least greater than the spatial separation required to deploy the array of protective plates. The value of the movable clearance X is 10-15mm generally.

In this embodiment, as shown in fig. 6, hinge holes are provided on both sides of each of the protection plates 31, and the adjacent protection plates 31 may be hinged by cooperation of the hinge rods 32 and the aligned hinge holes. Moreover, every two hinge rods 32 for hinging the protection plates 31 are in a group, and two ends of one hinge rod 32 in each group are in sliding fit with the sliding grooves 200, so that the protection plate group can be folded in a tooth shape and stored in the storage cavity 100; and further, the space of the receiving cavity 100 can be reduced, and the unfolding and folding of the protection plate group can be kept stable.

In this embodiment, as shown in fig. 5 to 7, the side portion of the sliding groove 200 is provided with a positioning groove 220, the second spring 500 is installed in the positioning groove 220, and the positioning groove 220 and the sliding groove 200 are communicated through the communication groove 210. The hinge rod 32 at one end of the protection plate group close to the plug penetrates through the communicating groove 210 through the connecting block 320 arranged at the end part to extend into the positioning groove 220 and is connected with the second spring 500, and the second spring 500 is always in a compressed state; so that the shielding plate group can perform shielding of the plug port under the elastic force of the second spring 500 when the pulling plate 2 is pulled.

It will be appreciated that the second spring 200 is prevented from bending when compressed by the detent 220. Meanwhile, the driving force generated by the second spring 200 to the protection plate assembly when the protection plate assembly is folded is smaller than the magnetic force or the elastic force between the pulling plate 2 and the switch box body 1, so as to prevent the pulling plate 2 from being jacked up by the protection plate assembly.

In one embodiment of the present application, as shown in fig. 3, 6 and 11, the shielding member 3 is provided with a locking hole 310; a mounting groove 120 is formed in the switch box body 1, and a lock rod 700 is elastically and slidably mounted in the mounting groove 120 through a third spring 600; when the protection component 3 seals the port of the plug, the locking hole 310 is aligned with the mounting groove 120, and then the locking bar 700 can be inserted into the locking hole 310 to lock the protection component 3, so that the protection component 3 can be prevented from being opened by children.

It is understood that the insertion of the locking hole 310 and the locking lever 700 may be achieved by the elastic force of the third spring 600; that is, when the shielding member 3 seals the port of the plug, the locking bar 700 may slide along the mounting groove 120 under the elastic force of the third spring 600 until the locking bar 700 is inserted into the locking hole 310.

Meanwhile, the insertion of the lock hole 310 and the lock bar 700 can also be realized through magnetic adsorption; that is, magnetic attraction can be performed between the lock lever 700 and the shield member 3; when the protective part 3 seals the port of the plug, the locking bar 700 can pull the third spring 600 to slide along the mounting groove 120 until the third spring is inserted into the locking hole 310 under the attraction of magnetic force.

When the protection component 3 needs to be unlocked, the pulling plate 2 is pulled to drive the protection component 3 to be separated from the locking hole 310 and the locking rod 700 to realize unlocking.

In this embodiment, the number of the mounting grooves 120 may be determined according to the number of the shielding members 3, and in order to improve the locking effect, locking may be performed on both upper and lower portions of each shielding member 3. That is, the number of the mounting grooves 120 is twice as many as the number of the shield members 3, and in order to further improve the locking effect, the mounting grooves 120 are provided at positions of the switch box body 1 near the plug.

The foregoing has described the general principles, essential features, and advantages of the application. It will be understood by those skilled in the art that the present application is not limited to the embodiments described above, which are merely illustrative of the principles of the application, but that various changes and modifications may be made without departing from the spirit and scope of the application, and these changes and modifications are intended to be within the scope of the application as claimed.
