Detailed Description
In order to make the technical solution of the present invention better understood by those skilled in the art, the technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.
Referring to fig. 1 to 11, a key switch protecting cover of an escalator or a moving walk according to the present embodiment includes a lower case 3 cooperating with a key switch and an upper case 4 cooperating and fastened with the lower case 3, wherein the lower case 3 is provided with a buckle 34 for fixing the lower case 3 on an operation panel 1 of the escalator or moving walk, and the operation panel 1 of the escalator or moving walk is provided with a bayonet 11 cooperating with the buckle 34; the lower shell 4 is provided with a through hole 33 matched with the top of the key switch 2, and the diameter of the through hole 33 is larger than or equal to the outer diameter of the top of the key switch 2. As shown in fig. 9 to 10, the key switch 2 has a long cylindrical shape, a part of which is exposed outside the operation panel 1, and a key hole 21 into which a key is inserted is formed in the key switch 2, so that the internal circuit is easily shorted by water inflow, and danger occurs.
As shown in fig. 3 to 7, the lower case 3 includes an annular bottom plate 31 and a screw ring 32 provided above the annular bottom plate 31, the screw ring 32 being an external screw thread, and the upper case 4 having an internal screw thread fitted with the screw ring 32. The provision of the screw thread facilitates the separation or combination of the upper case 4 and the lower case 3.
As shown in fig. 3-4, the buckles 34 are uniformly distributed on one side of the lower case 3 close to the operation panel 1, and in this embodiment, two buckles 34 are symmetrically arranged on the annular bottom plate 31. The buckles 34 are evenly distributed, so that the binding force between the lower shell 3 and the operation plate 1 is more even and the binding is more compact.
As shown in fig. 4, the catch 34 includes a vertical portion 35 perpendicular to the operation plate 1 and a hook portion 36 for hooking the operation plate 1. The vertical portions 35 penetrate the bayonet 11 of the operation panel 1, and the hook portions 36 are located on the sides of the corresponding vertical portions 35 away from each other.
As shown in fig. 2, the distance between the hook 36 and the annular bottom plate 31 matches the thickness of the operation plate 1. The distance between the hook 36 and the annular bottom plate 31 may be slightly smaller than or equal to the thickness of the operation plate 1 so that the lower case 3 can be tightly fixed on the operation plate 1.
As shown in fig. 3 to 4, the outer diameter of the screw ring 32 is smaller than the outer diameter of the annular bottom plate 31, and the thickness of the side edge of the upper shell 4 is equal to the distance from the outer side of the screw ring 32 to the outer side of the annular bottom plate 31, so that the upper shell 4 is flush with the side edge of the lower shell 3 when the upper shell 4 is screwed on the lower shell 3, thereby having better waterproof effect and being more concise and beautiful in appearance.
As shown in fig. 2-4 and 8, the key switch protecting cover in this embodiment further includes a gasket 5, a clamping groove 37 matched with the gasket 5 is formed on one side of the lower shell 3 close to the operation plate 1, and the clamping groove 37 in this embodiment is located below the thread ring 32. The waterproof effect can be better achieved by the arrangement of the gasket 5.
The thickness of the gasket 5 is equal to or greater than the depth of the clamping groove 37. When the lower case 3 is fixed to the operation panel 1, a certain pressure is applied to the gasket 5, and the waterproof effect can be improved. In the embodiment, the gasket is a rubber ring, and is cheap, practical, durable and good in waterproof effect.
When the key switch protection cover of the embodiment is installed and used, the gasket 5 is matched and placed into the clamping groove 37 of the lower shell 3, then the clamping buckle 34 of the lower shell 3 is correspondingly inserted into the clamping buckle 11 of the operation plate 1, after the clamping buckle is inserted into place, the hook 36 hooks the operation plate 1, and the gasket 5 is pressed on the operation plate 1 by the lower shell 3 through the clamping groove 37, so that a good sealing and waterproof effect is achieved. The upper shell 4 is then screwed onto the lower shell 3 by means of the cooperating screw thread arrangement, so that a better waterproof effect is achieved.
The key switch protecting cover of the embodiment consists of a lower shell 3, an upper shell 4 and a rubber ring 5. The rubber ring 5 is arranged in the clamping groove below the lower shell 3, the thickness of the rubber ring 5 is slightly thicker than the depth of the clamping groove, and the rubber ring 5 protrudes slightly from the lower surface of the lower shell 3. When the buckle of the lower shell 3 is clamped on the escalator operation panel 1, the rubber ring 5 is pressed tightly under the action of external force, so that the waterproof effect between the lower shell 3 and the operation panel 1 can be achieved. The lower shell 3 and the upper shell 4 can be effectively waterproof by threaded connection, the lower shell 3 is an external thread, and the upper shell 4 is an internal thread. Through the above structural design, under the condition of outdoor rainy days, rainwater can be effectively prevented from penetrating into the key switch 2, so that the internal circuit of the key switch 2 is short-circuited, and the operation safety of an escalator or a moving walk and the personal safety of passengers are influenced.
The key switch protecting cover of the escalator or the moving walk has reasonable buckle self-locking structural design, consists of a lower shell, an upper shell and a rubber ring, can be applied to a key switch of an escalator or a moving walk operation board, protects the key switch from being invaded by water, avoids the influence on the running safety of the escalator or the moving walk and the personal safety of passengers caused by short circuit of a circuit inside the key switch due to the fact that the circuit inside the key switch is soaked by water, and is particularly suitable for outdoor non-shielding moving escalators or moving walkways.
The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the present invention and to implement the same, but are not intended to limit the scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of the present invention.
