Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
The tamper casing that the utility model is provided, including upper casing 1 and lower casing 2, as described in Figure 1, the top of upper casing 1
Resilient key 11 is provided with, the side of upper casing 1 is provided with straight pin 12, and resilient key 11 and straight pin 12 are fixed on by riveting dress
On upper casing 1, as shown in figure 3, cross resilient slotted 112 is offered on the body of resilient key 11 vertically, the body of resilient key 11 from
Front end, which is risen, is disposed with the guiding conical surface 111, the anti-skidding conical surface 113 and spacing plane 114, and the diameter of the anti-skidding conical surface 113 is big
In the diameter for being oriented to the conical surface 111.
As shown in Fig. 2 being respectively arranged with the bullet that size is matched with the relative place of resilient key 11 and straight pin 12 on lower casing 2
Property pin-and-hole 25 and cylinder cotter way 26, when upper casing 1 is assembled with lower casing 2, straight pin 12 and resilient key 11 are individually fixed in cylinder
With the casing cavity of formation closing in cotter way 26 and elastic pin-and-hole 25.
In the preferred embodiment, as shown in figure 4, upper and lower enclosure assembles preceding state, by two cylinders of the both sides of upper casing 1
Pin 12 enters in the cylinder cotter way 26 of lower casing 2 simultaneously, and shifts bottom land position onto, the resilient key 11 of upper casing 1 is directed at lower machine
The elastic pin-and-hole 25 of shell 2, firmly presses upper casing 1, when upper and lower enclosure closed elastic pin 11 inserts elastic pin-and-hole 25, resilient key 11
The guiding conical surface 111 first touch elastic pin-and-hole 25, guiding is played in the case of out-of-alignment with elastic pin-and-hole 25 in resilient key 11
Effect, continues to push upper casing 1, elastic cross fluting 112 can make the anti-skidding conical surface 113 of resilient key pass through elasticity to contract
Pin-and-hole 25, makes resilient key 11 pass through elastic pin-and-hole 25, until on the elastic pin-and-hole 25 of the spacing plane 114 of resilient key and lower casing 2
Plane contact, while resilient key cross fluting 112 outwards flicks and resilient key 11 is stuck in completely on elastic pin-and-hole 25, now above and below
Casing assembling is completed, as shown in Figure 5；
Fig. 6 show sectional view after the completion of upper and lower enclosure assembling, and which show the bearing pin of upper casing straight pin 12 after assembling
With the position relationship of the elastic pin-and-hole 25 of lower casing cylinder cotter way 26, the bearing pin of upper casing resilient key 11 and lower casing, wherein cylinder
In the fully-inserted cylinder cotter way 26 of bearing pin of pin 12, straight pin 12 is fitted completely with the top and bottom of cylinder cotter way 26, elastic pin shaft 11
Spacing plane 114 fitted completely with the upper plane of elastic pin-and-hole 25, and the resilient key anti-skidding conical surface 113 and elastic pin-and-hole 25
Hole face is interference fitted, and resilient key bore dia is smaller than resilient key conical surface diameter, is made elastic pin shaft 11 and the complete clamping of elastic pin-and-hole, is protected
The fastness after upper and lower enclosure assembling is demonstrate,proved.
After the completion of upper and lower enclosure assembling, the fasteners such as any screw be can't see in outside, when user wants to take apart upper and lower enclosure,
Have no way of doing it；When specialized maintenance personnel tear apparatus casing open, only straight screwdriver need to be used to prize lower casing front end with certain force
Vertical plane on opening groove 2 put, two resilient keys 11 in left and right is departed from from elastic pin-and-hole 25, and prize opening groove 24
Position is to disassemble key point.Relatively hidden in order to disassemble key point, opening groove 24 is relatively small；In order to which upper and lower enclosure can not
It is opened easily, housing can not be damaged when taking apart, the contact engaging and separating force of resilient key 11 and pin-and-hole 25 will be got hold of；To make in upper casing 1
Straight pin 12 easily enters the cylinder cotter way 26 of lower casing 2, and cylinder cotter way is equipped with chamfering about 26.
Meanwhile, upper casing 1 and lower casing 2 can open indicator lamp as needed, and now can be set inside lower casing 1 has instruction
Lamp connector hole 2-3；Device is additionally provided with lower casing 2 stud 21 and outside installation self-clinching nut 22 are installed, can be according to reality
The outside position for installing self-clinching nut of use requirement change, and installed according to internal mounting related components difference change installing device
The quantity of stud 21 and position.
To sum up shown, what the utility model was provided assembles the simple, casing with certain tamper function, and it can be in equipment
Shell is easily assembled and completed by inside after installing, and outside without installed parts such as any screws, it is ensured that user
Apparatus casing will not be taken apart easily, specialized maintenance personnel is relatively easily opened housing, and will not be caused to housing
Damage.Housing of the present utility model have tailored appearance, light structure, handling ease, it is easy to assembly, disassemble the spies such as key point is hidden
Point.
Although the utility model is disclosed as above with preferred embodiment, so it is not limited to the utility model, any
Those skilled in the art, are not departing from spirit and scope of the present utility model, when can make a little modification and perfect, therefore this
The protection domain of utility model is when by being defined that claims are defined.
