The casing assembling structure without screw that screw is fixed.
For reaching this purpose, this utility model by the following technical solutions:
A kind of without screw casing assembling structure, including upper shell, lower house, it is arranged at described upper shell and institute
Stating the center between lower house, the circumference of described center medial wall is evenly equipped with T-shaped positionable wall, and described T-shaped is fixed
Position wall includes first straight wall vertically disposed with described center medial wall, and vertical with described first straight wall sets
The second upstanding wall put；The circumference of described upper shell and described lower house medial wall is respectively arranged with the first clamping wall
With the second clamping wall, the circumference of described first clamping wall and the second clamping wall is respectively separated and is evenly equipped with and described
The draw-in groove that one straight wall and second upstanding wall fasten, and the circumference of described first clamping wall is provided through hole clipping,
Described hole clipping and circumference are distributed in the grab phase clamping of described second clamping wall, adjacent described T-shaped positionable wall it
Between center medial wall on be provided with for the spacing straight wall of described upper shell and described lower house, described straight wall
Both ends of the surface shell inner surface with described upper shell and lower house respectively fit.
Wherein, match with described upper shell and described lower house respectively in upper surface and the lower surface of described center.
Wherein, described upper shell, described lower house and described center all use injection moulding integrated molding.
The beneficial effects of the utility model: this utility model includes upper shell, lower house, is arranged on described
Center between housing and described lower house, the circumference of described center medial wall is evenly equipped with T-shaped positionable wall, institute
State T-shaped positionable wall and include first straight wall vertically disposed with described center medial wall, and first straight with described
The vertically disposed second upstanding wall of wall；The circumference of described upper shell and described lower house medial wall is respectively arranged with
One clamping wall and the second clamping wall, the circumference of described first clamping wall and the second clamping wall is respectively separated and is evenly equipped with
The draw-in groove fastened with described first straight wall and second upstanding wall, and the circumference of described first clamping wall runs through setting
Hole clipping, described hole clipping is had to be distributed in the grab phase clamping of described second clamping wall, adjacent described T-shaped with circumference
It is provided with for the spacing straight wall of described upper shell and described lower house on center medial wall between positionable wall,
The both ends of the surface of described straight wall shell inner surface with described upper shell and lower house respectively fits.In this way
The casing assembling structure without screw of design, it is possible to make upper and lower casing and center para-position accurately, and pass through
Straight wall is arranged, and upper shell and lower house plays good support effect, and then limits the shifting of each degree of freedom
Dynamic, and then make to assemble reliable and stable, and play the purpose of convenient dismounting.
Accompanying drawing explanation
Fig. 1 is the exploded view of a kind of casing assembling structure without screw of this utility model.
Fig. 2 is the partial enlarged drawing in Fig. 1 at A.
Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by detailed description of the invention
As shown in Figures 1 and 2, a kind of without screw casing assembling structure in the present embodiment, including upper shell 1,
Lower house 2, the center 3 being arranged between described upper shell 1 and described lower house 2, inside described center 3
The circumference of wall is evenly equipped with T-shaped positionable wall, and described T-shaped positionable wall includes set vertical with described center 3 medial wall
The first straight wall 31 put, and with the described first vertically disposed second upstanding wall of straight wall 31 32；Described upper casing
The circumference of body 1 and described lower house 2 medial wall is respectively arranged with the first clamping wall 11 and the second clamping wall 21,
The circumference of described first clamping wall 11 and the second clamping wall 21 is respectively separated and is evenly equipped with and described first straight wall 31
The draw-in groove 211 fastened with second upstanding wall 32, and the circumference of described first clamping wall 11 is provided through hole clipping
111, described hole clipping 111 and circumference are distributed in the grab 212 phase clamping of described second clamping wall 21, described
Match with described upper shell 1 and described lower house 2 respectively in the upper surface of center 3 and lower surface, adjacent institute
State and be provided with for described upper shell 1 and described lower house 2 on center 3 medial wall between T-shaped positionable wall
Spacing straight wall 34, the both ends of the surface of described straight wall 34 respectively with in the housing of described upper shell 1 and lower house 2
Surface fits.
The upper surface of further described center 3 and lower surface respectively with described upper shell 1 and described lower house 2
Matching, described upper shell, described lower house and described center all use injection moulding integrated molding.
Use the casing assembling structure without screw of said structure design, it is possible to make upper and lower casing accurate with center
