Detailed Description

Referring to fig. 1-4, the present utility model provides a technical solution: the utility model provides a can dismantle casing, including organism 1, the fixed cover of surface of organism 1 is equipped with first casing 2, the downside of organism 1 is provided with second protecting crust 3, the recess identical with the downside of organism 1 is seted up to the upper surface of second protecting crust 3 simultaneously, simultaneously the upper surface of second protecting crust 3 coincide with the lower surface of first casing 2, consequently through installing second protecting crust 3 in the downside of first casing 2, the downside of organism 1 is wrapped up in to the recess on second protecting crust 3 like this, this makes first casing 2 and second protecting crust 3 form the protective effect to organism 1, simultaneously organism 1, first casing 2 and second protecting crust 3 make up the back with current model: HTCD820u smart phone is the same.

In this scheme, set up on the second protective housing 3 with the button of organism 1, charge mouth and camera identical mounting groove, second protective housing 3 can not receive the jam in the installation like this second protective housing 3.

Further, the upper surface of the second protective shell 3 is fixedly connected with a square butt joint block 4, and the lower surface of the first shell 2 is provided with a square butt joint groove 5 which is matched with the square butt joint block 4, so when the second protective shell 3 is arranged on the lower side of the first shell 2, the square butt joint block 4 is matched with the square butt joint groove 5 in a butt joint manner, the butt joint precision between the second protective shell 3 and the first shell 2 is improved, the problem that the second protective shell 3 is horizontally loosened is also prevented, and the firmness of the second protective shell 3 after being arranged is further ensured.

Through this kind of mode makes this smart mobile phone drain pan be detachable, like this when this smart mobile phone is in the use the drain pan receive stubborn spot pollution such as pigment, can demolish second protection shell 3, just so can put into ultrasonic cleaner to second protection shell 3 and carry out high-efficient cleanness to the dirty unclean condition of stubborn spot on the smart mobile phone drain pan can not appear, has further improved the holistic aesthetic property of this smart mobile phone, has ensured the travelling comfort when the user uses this smart mobile phone.

Further, the side of the first housing 2 is fixedly connected with the mounting plate 6, the side of the second protecting housing 3 is fixedly connected with the control block 7, meanwhile, the control block 7 and the mounting plate 6 are in the same vertical position, the lower surface of the mounting plate 6 is fixedly connected with the extension column 8, the lower side of the extension column 8 is arranged into an inverted right-angle trapezoid shape, and the upper surface of the control block 7 is provided with the extension groove 9 which is matched with the extension column 8, so that when the second protecting housing 3 is mounted on the lower side of the first housing 2, the extension column 8 extends into the extension groove 9.

Further, a control cavity 11 is formed in the control block 7, a fixed slide bar 12 is arranged in the control cavity 11, one end of the fixed slide bar 12 penetrates into the extension groove 9 in a sliding manner, one end of the fixed slide bar 12 positioned in the extension groove 9 is hemispherical, and a fixed groove 10 which is matched with the fixed slide bar 12 is formed in the surface of one side of the extension column 8 facing the fixed slide bar 12, so that when the fixed slide bar 12 extends into the fixed groove 10, the fixed slide bar 12 has a limiting effect on the extension column 8, and the extension column 8 is fixed in the extension groove 9.

Further, one end of the fixed slide bar 12 located in the control cavity 11 is fixedly connected with a limiting slide plate 13, the limiting slide plate 13 is in sliding connection with the inner wall of the control cavity 11, a tension spring 14 is fixedly connected between the limiting slide plate 13 and the inner wall of the control cavity 11, meanwhile, the tension spring 14 is movably sleeved on the outer surface of the fixed slide bar 12, when the tension spring 14 is not pulled, the tension spring 14 pulls the limiting slide plate 13 to enable the initial position of the limiting slide plate 13 to be close to one side of the extension groove 9, one end of the fixed slide bar 12 extends into the extension groove 9, when the extension column 8 moves into the extension groove 9, the inclined surface on the extension column 8 is in contact with the fixed slide bar 12 and extrudes the fixed slide bar 12, so that the fixed slide bar 12 gradually moves into the control cavity 11, meanwhile, the tension spring 14 stretches, when the extension column 8 extends into the extension groove 9 completely, the fixed slide bar 12 and the fixed groove 10 are located at the same horizontal position, and fixing of the extension column 8 is completed by pulling the tension spring 14.

Further, a pull rod 15 is fixedly connected to the surface of one side of the limiting slide plate 13, which is opposite to the fixed slide rod 12, the other end of the pull rod 15 penetrates through the outer surface of the control block 7 in a sliding manner, and a pull plate 16 is fixedly connected to one end of the pull rod 15, which is located outside the control block 7, so that the fixed slide rod 12 can be pulled out of the fixed groove 10 by pulling the pull plate 16 by the pull rod 15, and separation between the extension column 8 and the extension groove 9 is completed.

In this scheme, through setting up the one end that fixed slide bar 12 is located extending groove 9 to hemispherical, increased the smooth degree of fixed slide bar 12 and extending post 8 surface contact surface like this to the frictional force that produces when having reduced fixed slide bar 12 and sliding along extending post 8 surface, consequently avoided appearing the dead problem of machinery card between fixed slide bar 12 and the extending post 8, ensured fluency and stability when this mechanism uses.

Working principle: when the extension column 8 is displaced into the extension groove 9, the inclined surface on the extension column 8 is contacted with the fixed slide rod 12 and extrudes the fixed slide rod 12, so that the fixed slide rod 12 is gradually displaced into the control cavity 11, meanwhile, the tension spring 14 is stretched, when the extension column 8 is completely extended into the extension groove 9, the fixed slide rod 12 and the fixed groove 10 are positioned at the same horizontal position, and therefore, the fixed slide rod 12 is displaced into the fixed groove 10 under the pulling of the tension spring 14, and the fixation of the extension column 8 is completed;

by pulling the pulling plate 16, the pulling rod 15 can pull the fixed slide rod 12 out of the fixed groove 10, thereby completing the separation between the extension column 8 and the extension groove 9.
