Description

Technical Field

[0001] The utility model relates to a remote control handle, in particular to a wireless remote control handle which is dust-proof and easy to store. Background Art

[0002] At present, remote control handles are increasingly used in factories to remotely control machinery and equipment. For example, a machine tool is remotely controlled by a machine tool remote control handle. The usage environment of remote control handles in factories is usually relatively harsh. If metal-containing powder enters the remote control handle, it will cause great damage to the circuit board inside the remote control handle. Therefore, the service life of remote control handles used in conductive dust environments is usually short. In addition, wireless remote control handles are usually independent components, which are portable and easy to use. However, because they are not directly connected to the controlled equipment such as machine tools through signal lines, when the remote control handle needs to be stored temporarily during or after use, it is not easy to place because there is no special placement position, or although there is a special placement position, the operator places the remote control handle randomly in a nearby slot, hole or crossbar for convenience. These positions are usually not conspicuous. On the one hand, this causes the operator to often spend time looking for the remote control handle. On the other hand, the remote control handle placed on the surface of the platform or crossbar is also easily accidentally touched and dropped by the operator and damaged. Summary of the Utility Model

[0003] The utility model provides a wireless remote control handle which is dust-proof and easy to store, aiming to overcome the above deficiencies in the prior art to at least a certain extent.

[0004] The technical solution for the utility model to solve the above technical problems is as follows: A wireless remote control handle which is dust-proof and easy to store, includes a front shell, a rear shell and a circuit board encapsulated in the front shell and the rear shell. A plurality of key switches are connected to the surface of the circuit board. Key holes corresponding to the key switches one by one are opened on the front panel of the front shell. A surrounding plate one extending backward is provided around the periphery of the front panel. A surrounding plate two extending forward is provided around the periphery of the rear panel of the rear shell. A plurality of cooperating snap members are provided on the inner side surfaces of the surrounding plate one and the surrounding plate two. A U-shaped dust-proof groove and a dust-proof rib are correspondingly provided on the rear end surface of the surrounding plate one and the front end surface of the surrounding plate two. When the front shell is covered on the rear shell, it is snap-fixed through the snap members and the dust-proof rib is inserted into the dust-proof groove. A plurality of strong magnetic blocks are snap-fixed on the front side of the rear panel of the rear shell. Elastic pressing blocks are sealed and fixed in the key holes. A protective film covering each of the elastic pressing blocks is pasted on the front side of the front panel of the front shell.

[0005] On the basis of the above technical solution, the utility model can also be improved as follows.

[0006] Further, a limiting dust-proof enclosure extending rearward is provided on the inner side of the front panel of the front housing, inside the first enclosure panel. The periphery of the circuit board is closely attached to the inner periphery of the limiting dust-proof enclosure, and a plurality of fixing buckles for pressing the circuit board into the limiting dust-proof enclosure are provided on the rear end surface of the limiting dust-proof enclosure.

[0007] Further, there are four fixing buckles, two of which are located at the top of the limiting dust-proof enclosure, and the other two are located at the bottom of the limiting dust-proof enclosure.

[0008] Further, a step groove for pressing the periphery of the circuit board into is provided on the inner side of the upper end surface of the limiting dust-proof enclosure.

[0009] Further, a plurality of first fixing columns for screwing in the first screw are provided on the rear side of the front panel of the front housing, and fixing holes corresponding to the first fixing columns are provided on the circuit board. One end of the first screw passes through the fixing hole and is screwed into the first fixing column.

[0010] Further, corresponding second fixing columns for screwing in the second screw are provided inside the front housing and the rear housing.

[0011] Further, a groove for the strong magnetic block to be snapped into is formed on the front side of the rear panel of the rear housing by a plurality of limiting ridges and / or convex columns. A plurality of anti-detachment buckles for preventing the strong magnetic block from detaching from the groove opening are provided at the groove opening of the groove.

[0012] Further, there are two strong magnetic blocks arranged at an interval up and down, and the strong magnetic blocks are neodymium iron boron magnets.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] A dust-proof groove and a dust-proof ridge that cooperate with each other are provided at the joint where the front housing and the rear housing are covered with each other. After the dust-proof ridge is snapped into the dust-proof groove, a U-shaped dust-proof path is formed. The dust-proof path is long and the dust-proof effect is good. In addition to this dust-proof structure, when the circuit board is snapped into the front housing, it is protected by the surrounding limiting dust-proof enclosure. The two are closely attached at the step groove. Therefore, even if dust enters the inside of the front and rear housings, due to the second protection of the limiting dust-proof enclosure, it can still prevent the electronic components on the front side of the circuit board from contacting and being damaged by dust, and the dust-proof effect is good.

[0015] The strong magnetic block is snap-connected and fixed to the front side of the rear panel of the rear housing. When the remote control handle is not in use or needs to be temporarily stored during use, it can be adsorbed to any object made of steel through the strong magnetic block on the rear housing nearby. There is no need to deliberately find a platform, crossbeam or groove, gap and other inconspicuous positions for storage. It is not only convenient for storage, but also magnetically adsorbed on the more conspicuous position on the surface of the object, which is also convenient for quickly and conveniently finding or taking the remote control handle when it is needed for subsequent use.

[0024] The principles and features of the present utility model will be described below with reference to the accompanying drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0025] In the description of the present utility model, if terms indicating directions such as "upper", "lower", "left", "right", "top", "bottom", "inner", "outer", etc. are used, the directions or positional relationships indicated are based on the directions or positional relationships shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be construed as a limitation to the present utility model.

[0026] Such as Figures 1 to 6As shown in the figure, the utility model provides a wireless remote control handle that is dust-proof and easy to store, which includes a front housing 1, a rear housing 2, and a circuit board 3 encapsulated in the front housing 1 and the rear housing 2. A plurality of key switches 4 are connected to the surface of the circuit board 3. Key holes 5 corresponding to the key switches 4 one by one are provided on the front panel of the front housing 1. A circle of backward enclosing plate one (or rear flanging) is provided around the periphery of the front panel. A circle of forward enclosing plate two (or front flanging) is provided around the periphery of the rear panel of the rear housing 2. A plurality of cooperating buckle members 6 are provided on the inner side surfaces of the enclosing plate one and the enclosing plate two. U-shaped dust-proof grooves 7 and dust-proof ridges 8 are correspondingly provided on the rear end surface of the enclosing plate one and the front end surface of the enclosing plate two. When the front housing 1 is covered on the rear housing 2, it is clamped and fixed through the buckle members 6, and the dust-proof ridge 8 is inserted into the dust-proof groove 7. A plurality of strong magnetic blocks 9 are clamped and fixed on the front side of the rear panel of the rear housing 2. An elastic pressing block 10 is sealed and fixed in the key hole 5. The elastic pressing block not only seals the key hole to prevent dust from entering the housing from the front panel and contacting the components on the circuit board, but also provides a key function of being deformed under pressure. A protective film covering each elastic pressing block 10 is pasted on the front side of the front panel of the front housing 1. The protective film can be provided with characters or symbols indicating the function of each key.

[0027] It should be noted that the dust-proof ridge matches the U-shaped dust-proof groove. After the dust-proof ridge is snapped into the dust-proof groove, if dust wants to enter the housing through the gap at the connection between the front and rear housings, it must pass through the relatively long U-shaped dust-proof path. Therefore, dust is not easily penetrated into the housing, achieving the dust-proof purpose. The buckle member includes a hook and a hanging ring structure, specifically as Figures 2 to 4 shown. It is a commonly used structure during clamping. The specific structure and the setting position are well-known to those skilled in the art, so they will not be elaborated here. The strong magnetic block is located inside the housing, and its function is to attract and combine with an object adsorbed by a magnet such as a steel material through the rear panel of the rear housing, so as to conveniently adsorb the remote control handle on the surface of the object. Thus, it is not necessary to be limited to placing the remote control handle on the flat surface, groove or gap of the object, and it is relatively stable after adsorption. General touch is not easy to cause it to fall off, and it is less likely to be knocked off and damaged compared to placing it on a platform, etc.

[0028] In an embodiment of the utility model, a circle of limiting dust-proof enclosing plate 11 extending backward is provided on the rear side of the front panel of the front housing 1 inside the enclosing plate one. The periphery of the circuit board 3 is closely attached to the inner periphery of the limiting dust-proof enclosing plate 11, and a plurality of fixing buckles 12 for pressing the circuit board 3 into the limiting dust-proof enclosing plate 11 are provided on the rear end surface of the limiting dust-proof enclosing plate 11.

[0029] It should be noted that the fixing buckle is preferably made of a hard and elastic material; the shape of the periphery of the circuit board matches the shape of the limiting dust-proof enclosing plate.

[0030] In an embodiment of the present utility model, four fixing buckles 12 are provided, two of which are located at the top of the limiting dust-proof enclosure 11, and the other two are located at the bottom of the limiting dust-proof enclosure 11.

[0031] It can be understood that the fixing buckles can be provided not only at the top and bottom of the limiting dust-proof enclosure, but also on the left and right sides.

[0032] In an embodiment of the present utility model, a step groove 13 for pressing the periphery of the circuit board 3 is provided on the inner side of the upper end surface of the limiting dust-proof enclosure 11.

[0033] It should be noted that the step groove has two functions. One is to provide support for the circuit board from the front, and the other is to lengthen the dust-proof path to ensure the dust-proof effect of the second dust-proof measure.

[0034] In an embodiment of the present utility model, a plurality of first fixing columns 14 for screwing in the first screw are provided on the rear side of the front panel of the front housing 1, and fixing holes corresponding to the first fixing columns 14 are provided on the circuit board 3. One end of the first screw passes through the fixing hole and is screwed into the first fixing column 14.

[0035] It should be noted that the first screw is used to lock the circuit board in the front housing, and its function does not conflict with that of the fixing buckle. The fixing buckle is beneficial to the quick installation and positioning of the circuit board, so as to facilitate the alignment of the first screw with the screw hole on the first fixing column. The first screw makes the fixing effect of the circuit board and the front housing better.

[0036] In an embodiment of the present utility model, corresponding second fixing columns 15 for screwing in the second screw are provided in the front housing 1 and the rear housing 2.

[0037] Similarly, the function of the second screw does not overlap with that of the buckle member, and it has the functions of facilitating installation and providing double insurance.

[0038] In an embodiment of the present utility model, a groove body for the strong magnetic block 9 to be snapped into is formed on the front side of the rear panel of the rear housing 2 by a plurality of limiting convex strips and / or convex columns, and a plurality of anti-detachment buckles 16 for preventing the strong magnetic block 9 from detaching from the groove opening are provided at the groove opening of the groove body of the limiting convex strips.

[0039] In an embodiment of the present utility model, there are two strong magnetic blocks 9 which are arranged at intervals up and down, and the strong magnetic block 9 is a neodymium iron boron magnet.

[0040] It should be noted that the rear panel of the rear housing should be made of a material that can transmit magnetism, that is, the strong magnetic block can attract objects such as steel that can be attracted by magnets through it.

[0041] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
