Specific implementation mode
In order that those skilled in the art will better understand the technical solution of the present invention, implement below in conjunction with the present invention
Attached drawing in example, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment
Only a part of the embodiments of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is common
The every other embodiment that technical staff is obtained without making creative work, should all belong to protection of the present invention
Range.
Referring to Fig.1-11, the key switch protective cover of a kind of escalator of the present embodiment or moving sidewalk, including with
The mutually matched lower casing 3 of key switch and upper casing 4 with the cooperation fastening of lower casing 3, have on lower casing 3 by lower casing 3 be fixed on from
Offered on the operation panel 1 of buckle 34 on the operation panel 1 of dynamic staircase or moving sidewalk, escalator or moving sidewalk with
Buckle 34 matched bayonets 11；It is offered on lower casing 4 and the 2 matched through-hole 33 in top of key switch, the diameter of through-hole 33
More than or equal to the outer diameter at 2 top of key switch.As shown in figs. 9-10, key switch 2 is in long tubular, some is exposed grasping
Make the outside of plate 1, and offer the keyhole 21 being inserted into for key on key switch 2, easy water inlet leads to internal wiring
Short circuit, and then cause danger.
As shown in fig. 3 to 7, lower casing 3 includes annular base plate 31 and the fillet of screw 32 being arranged above annular base plate 31, spiral shell
Line circle 32 is external screw thread, and upper casing 4 has and 32 matched internal thread of the fillet of screw.The setting of screw thread facilitates upper casing 4 and lower casing 3
It is detached or is combined.
As shown in Figure 3-4, buckle 34 is evenly distributed on lower casing 3 on the side of operation panel 1, in ring-type in the present embodiment
Buckle 34 there are two being symmetrical arranged on bottom plate 31.Buckle 34 is uniformly distributed so that lower casing 3 and the binding force of operation panel 1 are more equal
It is even, in conjunction with even closer.
As shown in figure 4, buckle 34 includes the hook portion perpendicular to the vertical portion of operation panel 1 35 and for hooking operation panel 1
36.The bayonet 11 of operation panel 1 is run through in vertical portion 35, and hook portion 36 is located at the side that corresponding vertical portion 35 is located remotely from each other.
As shown in Fig. 2, the distance between hook portion 36 and annular base plate 31 and the thickness of operation panel 1 match.Hook portion 36 with
The distance between annular base plate 31 can be slightly less than or equal to operation panel 1 thickness so that lower casing 3 can closely be fixed on operation
On plate 1.
As shown in Figure 3-4, the outer diameter of the fillet of screw 32 is less than the outer diameter of annular base plate 31, the thickness and screw thread of 4 side of upper casing
The distance in circle 32 outside to the outside of annular base plate 31 is equal, in this way when upper casing 4 is screwed on lower casing 3 upper casing 4 and lower casing 3 side
Edge flushes, and can preferably play the effect of waterproof in this way, also more concise and beautiful in appearance.

Side offer with 5 matched card slot 37 of washer, and the card slot 37 that the present embodiment neutralizes is located at the lower section of the fillet of screw 32.It is logical
The effect of waterproof can preferably be played by crossing the setting of washer 5.
The thickness of washer 5 is more than or equal to the depth of card slot 37.In this way when lower casing 3 to be fixed on operation panel 1, to washer
5 form certain pressure, can preferably play the effect of waterproof.The present embodiment middle washer is rubber ring, cheap material benefit and
It is durable, good water-proof effect.
When the key switch protective cover of the present embodiment is installed and used, washer 5 is first coordinated to the card slot 37 for being put into lower casing 3
In, in the buckle 11 that the buckle 34 of lower casing 3 is then corresponded to insertion operation plate 1, after being inserted in place, hook portion 36 hooks operation panel 1,
And washer 5 is pressed on operation panel 1 by lower casing 3 by card slot 37, reaches good sealed waterproof effect.Then pass through the spiral shell of cooperation
Upper casing 4 is tightened on lower casing 3 by line setting, to reach better waterproof effect.
The key switch protective cover of the present embodiment is made of lower casing 3, upper casing 4 and rubber ring 5.Rubber ring 5 is mounted in lower casing 3
In the card slot of lower section, the thickness of rubber ring 5 is slightly thicker than the depth of card slot, and rubber ring 5 slightly protrudes from the lower surface of lower casing 3.Instantly
When the buckle of shell 3 is stuck in escalator operation panel 1, rubber ring 5 is compacted under external force, can play lower casing 3 and operation
Waterproof action between panel 1.Lower casing 3 and upper casing 4 be threadedly coupled can effective waterproof, lower casing 3 is external screw thread, and upper casing 4 is interior
Screw thread.In the case of making the rainy day outdoors by above structure design, rainwater can be effectively prevent to penetrate into key switch 2
Portion influences escalator or the person of moving sidewalk operational safety and passenger so as to cause 2 internal short circuits of key switch
Safety.
A kind of escalator of the present invention or the key switch protective cover of moving sidewalk, buckle self-locking structure design
Rationally, it is made of, is can be applicable on the key switch of escalator or moving sidewalk operation panel lower casing, upper casing and rubber ring,
Protection key switch prevents from being immersed by water, and short circuit can be led to and influence to help automatically by avoiding the circuit inside key switch from being soaked in water
Ladder or moving sidewalk operational safety and passenger's personal safety are particularly suitable for outdoor unobstructed escalator or from moving row
On road.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar cans understand the content of the present invention and implement it accordingly, and it is not intended to limit the scope of the present invention, all according to the present invention
