Summary of the invention
Technical problem to be solved by this invention provides a kind of easy to operate hinge-lid type snap close.
The technical solution adopted for the present invention to solve the technical problems is: a kind of hinge-lid type snap close is provided, comprises the threaded connecting rod of outer circumferential face, an end of described connecting rod is fixed on the projection of fixed block; Be provided with running shaft in the middle of the projection of described fixed block; Have can be around the turnover panel of described running shaft rotation for cover on the described running shaft.
Described turnover panel is provided with a depression that matches with described fixed block upper protruding block shape with the joint of running shaft.
Described turnover panel lower surface is provided with a buckle.
Beneficial effect
Owing to having adopted above-mentioned technological scheme, the present invention compared with prior art, have following advantage and good effect: the present invention is fixed piece at an end of connecting rod, and by running shaft reverse turning bed structure is linked to each other with fixed block, when reverse turning bed structure is dug, thereby just can hold the turnover panel rotation and drive the connecting rod rotation, realize locking easily and dismantling.
Embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiments only to be used for explanation the present invention and be not used in and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiments of the present invention relate to a kind of hinge-lid type snap close, this snap close is in order to be fixed on terminal with bonnet, bonnet is provided with one mounting hole of the present invention is installed, after the present invention is installed in the mounting hole, by screwed connecting rod just can with terminal on screw be fixed, thereby so that bonnet be fixed on the terminal.
As depicted in figs. 1 and 2, the present invention includes the threaded connecting rod 1 of outer circumferential face, an end of described connecting rod 1 is fixed on the projection 5 of semicircle fixed block 2; Be provided with running shaft 3 in the middle of the projection 5 of described semicircle fixed block 2; Have can be around the turnover panel 4 of described running shaft 3 rotations for cover on the described running shaft 3.Also be provided with a buckle 6 at turnover panel 4 lower surfaces, this buckle 6 can with the mutual clamping of back shroud.
Described turnover panel 4 is semicircular structure; Described turnover panel 4 when not dug and described fixed block 2 be combined into circle; The diameter place of the semicircular structure of described turnover panel 4 is provided with a depression that matches with described fixed block 2 upper protruding blocks 5 shapes.
Need to prove, the fixed block in the present embodiment and turnover panel can also adopt other shapes, such as rectangular fixed block and rectangular turnover panel, can not be combined into square etc. with fixed block when turnover panel is dug.
As shown in Figure 3, install when of the present invention, first back shroud is placed on the terminal, then connecting rod 1 is passed the mounting hole on the back shroud, screw thread and the screw on the terminal 7 on the connecting rod 1 is in contact with one another at this moment, then digs turnover panel 4, projection 5 on itself and the fixed block is about 90 degree, and hold turnover panel 4 and be rotated the present invention is screwed in the screw 7 with fixing, at last turnover panel 4 is turned down, make buckle 6 and the mutual clamping of back shroud.In the time of need to opening back shroud, first turnover panel 4 is dug, the projection 5 on itself and the fixed block is about 90 degree, and hold turnover panel 4 and be rotated the present invention is screwed out from screw 7, take off back shroud and get final product.
Be not difficult to find, the present invention is fixed piece at an end of connecting rod, and by running shaft reverse turning bed structure is linked to each other with fixed block, when reverse turning bed structure is dug, drives the connecting rod rotation thereby just can hold the turnover panel rotation, realizes locking easily and dismantling.
