The most existing back shell of interphone attachment structure lacks one can conveniently dismantle, and simple in construction, convenient operation, the structure that security performance is high.
Utility model content
The purpose of this utility model is to provide a kind of back shell of interphone attachment structure, it is intended to solve the problem in above-mentioned back shell of interphone installation process.
This utility model be the technical scheme is that a kind of back shell of interphone attachment structure, this structure is mainly used in the handling of back shell of interphone, this back shell of interphone attachment structure includes transmitter receiver main body, it is arranged on the locker of described transmitter receiver bottom part body, described locker includes jam plate, snap and pull plate, described transmitter receiver bottom part body is provided with flat-shaped cavity, described cavity offers the opening installing locker towards the transmitter receiver back side, described snap is pressed into described cavity by described opening by described jam plate, position bottom the corresponding described transmitter receiver of described cavity offers breach, described plate of pulling is fixed to be pressed into the jam plate of described cavity by described breach, locked groove is offered at the corresponding described locker in described back shell of interphone bottom.Back shell of interphone attachment structure in the application uses snap locker, convenient dismounting, auto lock, simple in construction, it is easy to make.
Further technical scheme of the present utility model is: bottom described back shell of interphone, the bottom towards described transmitter receiver main body one side is provided with the slotting projection of hook, and the corresponding described hook of described transmitter receiver main body is inserted protruding position and is provided with hook slot.Transmitter receiver does this arrange so that transmitter receiver main body and back shell of interphone are difficult to separate after grafting.
Further technical scheme of the present utility model is: bottom described back shell of interphone, the top towards described transmitter receiver main body one side is provided with grafting projection, and the corresponding described hook of described transmitter receiver main body is inserted protruding position and is provided with inserting groove.Transmitter receiver does this arrange so that transmitter receiver main body and back shell of interphone are difficult to separate after grafting.Avoid owing to the installation shakiness on top makes transmitter receiver main body separate with back shell of interphone.
Further technical scheme of the present utility model is: described locker includes two snaps being symmetricly set on bottom described jam plate.If a meeting that snap is difficult to avoid that makes jam plate offset after a long time use, cause jam plate top can not insert back shell of interphone smoothly.Arranging of two snaps can make stable the stretching of jam plate.
Further technical scheme of the present utility model is: described in pull plate and can move in described breach, described in pull strip and move described jam plate and stretch out described cavity or retraction.Arranging at this can avoid jam plate to eject cavity under the effect of snap, and conveniently controls the retraction of described jam plate, facilitates the dismounting of back shell of interphone.
The beneficial effects of the utility model are: the back shell of interphone attachment structure in the application uses snap locker, convenient dismounting, auto lock, simple in construction, it is easy to make.

Detailed description of the invention
nullA kind of back shell of interphone 2 attachment structure，This structure is mainly used in the handling of back shell of interphone 2，This back shell of interphone 2 attachment structure includes transmitter receiver main body 1，It is arranged on the locker 3 bottom described transmitter receiver main body 1，Described locker 3 includes jam plate 31、Snap 32 and pull plate 33，Flat-shaped cavity 11 it is provided with bottom described transmitter receiver main body 1，Described cavity 11 offers the opening 111 installing locker 3 towards the transmitter receiver back side，Described snap 32 is pressed into described cavity 11 by described opening 111 by described jam plate 31，Position bottom the corresponding described transmitter receiver of described cavity 11 offers breach 112，Described plate 33 of pulling is fixed to be pressed into the jam plate 31 of described cavity 11 by described breach 112，Locked groove 21 is offered at the corresponding described locker 3 in described back shell of interphone 2 bottom.
Bottom described back shell of interphone 2, the bottom towards described transmitter receiver main body 1 one side is provided with hook slotting protruding 12, and the corresponding described hook of described transmitter receiver main body 1 is inserted the position of protruding 12 and is provided with hook slot 22.
Bottom described back shell of interphone 2, the top towards described transmitter receiver main body 1 one side is provided with grafting projection 13, and the corresponding described hook of described transmitter receiver main body 1 is inserted the position of protruding 12 and is provided with inserting groove 23.
Described locker 3 includes two snaps 32 being symmetricly set on bottom described jam plate 31.
Described plate 33 of pulling can move in described breach 112, described in pull plate 33 drive described jam plate 31 stretch out described cavity 11 or retract.
Cavity 11 and locker 3 in the application are and are symmetrical arranged, and on the one hand such design can ensure that the steady of jam plate 31.On the other hand the making being also convenient for itself is implemented.The application pulls plate 33 as in figure 2 it is shown, pull plate 33 and be screwed on described jam plate 31.Described plate 33 of pulling is divided into two parts, a part to be used for connecting jam plate 31, and another part is that convex shape protrudes described cavity 11 to described breach 112.It is arcuation that the corresponding described jam plate 31 of described breach 112 stretches out direction, and concaves towards direction, the transmitter receiver back side.The described bossing pulling plate 33 is also arcuation, and shape is in opposite direction with breach 112 arcuation.Turning back of such locker 3 arranged after conveniently pinning.Such design can make to pull between plate 33 and described breach 112 space, facilitates the insertion of finger.
Described jam plate 31 is provided with multiple Plug Division, and described jam plate 31 is symmetrical arranged.Plug Division on described jam plate 31 can insert the locked groove 21 that described back shell of interphone 2 is provided with easily.
