Specific embodiment

In order to which technical problem to be solved in the utility model, technical solution and beneficial effect is more clearly understood, with Lower combination accompanying drawings and embodiments, the present invention will be further described in detail.It should be appreciated that specific reality described herein It applies example to be only used to explain the utility model, is not used to limit the utility model.

A kind of waterproof safety check keyboard, as depicted in figs. 1 and 2, including shell 1, mounting plate 2 and key 3, shell 1 are metal Material, on the whole substantially in a rectangular parallelepiped shape, mounting plate 2 are fixedly mounted on the inside of shell 1, and key 3 is then mounted on mounting plate 2 On.The top of shell 1 is equipped with a waterproof outlet joint 4, and the conducting wire of connection plate 2 is enable to be pierced by shell 1, operator The safety check operating system software that screening machine is operated by key 3, realizes the corresponding function of screening machine.

It is provided with key window 11 on shell 1, key 3 is enable to expose shell 1, in mounting plate 2 towards the table of key window 11 Face is then provided with the waterproofing membrane 5 (dotted line frame in Fig. 1 and Fig. 2 indicates waterproofing membrane 5) of one layer of covering key 3, waterproofing membrane 5 Shape and the shape of key window 11 match, and entire key window 11 can be covered.Waterproofing membrane 5 has water-proof function Film can stop hydrone or other fluid molecules to penetrate, it is preferred to use polyester film (PET) is preferably prevented because it has While aqueous and translucency, also there is good wearability and flexibility, Reusability is without easy to wear.Pass through above knot Structure can make safety check keyboard reach preferable waterproof effect, even if liquid is splashed on safety check keyboard, be also easily detected by by Key 3 infilters the inside of safety check keyboard and causes safety check keyboard Damage by Short Circuit.

As shown in Figures 2 and 3, the specific structure of shell 1 includes shell 12 and rear cover 13, and rear cover 13 passes through dismountable side Formula is mounted on shell 12, and surrounds the cavity to be formed for accommodating mounting plate 2.For example, rear cover 13 can be by way of buckle It is mounted on the rear portion of shell 12, or is mounted on the rear portion of shell 12 by screw.At this point, 3 window 11 of key is provided on shell 12, Mounting plate 2 is then fixedly connected with shell 12.When safety check keyboard is installed, key 3 and waterproofing membrane 5 etc. are first installed on mounting plate 2 Then mounting plate 2 is directed at key window 11 and is placed in shell 12 from the rear portion of shell 12 by structure, and fixed with shell 12, finally will Rear cover 13 is mounted on the rear portion of shell 12.It, can be by rear cover 13 from shell 12 when the internal structure of safety check keyboard needs repairing It removes, the structure inside shell 1 is taken out, in order to the maintenance of safety check keyboard.

Specifically, multiple fixation holes 121 are provided on shell 12, multiple 121 surrounding key window 11 of fixation hole distributions, and Multiple fixation holes 121 distinguish grafting just like screw, the isostructural connector 122 of pin, and mounting plate 2 passes through multiple connectors 122 It is fixedly connected with shell 12.The connector 122 and shell 12 that mounting plate 2 is distributed by multiple surrounding key windows 11 are fixed, and make to pacify Loading board 2 is more firmly mounted, and long-time service is also not easy to loosen.

As shown in Figures 2 to 4, further, one layer of elastic water-proof circle 6, elastic water-proof circle are additionally provided on mounting plate 2 6 are pressed between waterproofing membrane 5 and shell 1, and elastic water-proof circle 6 is using flexible water proof rings such as silica gel rings.Due to waterproof The surface of mounting plate 2 is arranged in film 5, and mounting plate 2 is fixedly connected with shell 1, and therefore, elastic water-proof circle 6 is pressed on waterproof Between film 5 and shell 1, the gap between shell 1 and mounting plate 2 can be sealed, avoid liquid from mounting plate 2 and shell 1 it Between gap penetrate into safety check keyboard inside, further increase the waterproof effect of safety check keyboard.

Mounting plate 2 includes the film fixed plate 21 being mutually permanently connected and circuit board 22, is provided with use in film fixed plate 21 In the mounting hole 211 of installation key 3, waterproofing membrane 5 covers mounting hole then by sticking double faced adhesive tape in film fixed plate 21 Key 3 in 211, key 3 are then electrically connected with circuit board 22.Key 3 is mounted in the mounting hole 211 in film fixed plate 21, Waterproofing membrane 5 is set to be pasted onto film fixed plate 21 relatively flatly, when waterproofing membrane 5 damages or need replacing key 3 When, can directly tear from film fixed plate 21 waterproofing membrane 5, keep the maintenance of safety check keyboard more convenient.

In addition, the key 3 in the present embodiment is directly weldingly fixed on circuit using standard independent key general on the market On plate 22, without installing button cap, structure is simpler, while having preferably pressing feel；And due to key 3, circuit It is kept fixed between plate 22 and film fixed plate 21, therefore when pressing keys 3, key 3 will not rub with the hole wall of mounting hole 211 It wipes, avoids phenomena such as generating card key, poor contact, the compression number of key 3 can be increased, improved service life.

Fig. 1 and Fig. 2 are reviewed, fingerprint instrument 71, switch 72, emergency stop knob 73 and touch tablet mouse 74 are also equipped on shell 1 Equal functional components.

Fingerprint instrument 71 is used for the logon rights of verification management safety check staff, when safety check staff is defeated by key 3 While entering entry password and corresponding password login safety check operating system, need safety check staff in 71 typing of fingerprint instrument The fingerprint of itself, the identity information with entry password and password cooperation verifying safety check staff, only verification information are whole Meet, safety check staff just can smoothly log in safety check operating system and carry out the operation to screening machine, dramatically protect The safe and reliable use of screening machine is demonstrate,proved.

The power supply that switch 72 is used to control screening machine switches on and off.

Emergency stop knob 73 is used to control the urgent pause of screening machine, during safety check work carries out, such as emergency case, Such as luggage and articles are stuck, can be by the control screening machine stopping rapidly of rotation emergency stop knob 73, and convenient for safety check, staff is answered Pay various emergency events.

Touch tablet mouse 74 is used for the use instead of common mouse, so that safety check keyboard combines together with mouse, convenient for peace The various operations in safety check operating system can be realized by safety check keyboard by inspection staff；Touch tablet mouse 74 specifically can be with For a kind of embedded high click service life touch tablet, it is made of PCB material, possesses high life, highly sensitive advantage.

Further, shell 1 is also equipped with advance key 81, stop key 82 and back spacer 83, and advance key 81 is for controlling peace Inspection machine conveys tape travel, and stop key 82 is for controlling the stopping of screening machine conveyer belt, and back spacer 83 is for controlling screening machine conveyer belt It retreats.The image display of safety check keyboard and screening machine, station matches, and completes every safety inspection, and function is more complete Face.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model Protection scope within.
