Abstract
The utility model discloses a screw for fixing a display module of an LED display screen, and relates to the field of a screw for fixing a display module of an LED display screen. The screw solves the technical problem that the existing screw drops off and is lost, and provides a screw for fixing a display module of an LED display screen, which can not be lost after being loosened. The screw comprises a screw rod and a screw cap, and is characterized in that the screw also comprises a connecting sleeve; a hollow cavity with a cavity opening in the direction of the screw rod is arranged on the screw cap; the tail end of the screw rod is arranged in the center of the bottom of the hollow cavity; the connecting sleeve is sleeved on the screw rod; one end of the connecting sleeve is arranged in the hollow cavity; an outer edge is arranged on the end; and an inner edge matched with and clamped with the outer edge on the connecting sleeve is arranged on the cavity opening of the hollow cavity. One end of the connecting sleeve is fixed on a module fixing plate of a box body in a press-riveting way, and before the display module is fixed and the display module is fixedly connected, people do not need to look for screw everywhere, the screw is convenient to use, and the work efficiency is improved.
Description
Technical field
The utility model relates to the screw technical field, refers more particularly to LED display and is used for fixing the screw field that shows that module is used.
Background technique
The demonstration module of traditional LED display all is with common screw it to be fixed on the display screen box body, in actual production process, a lot of screws are arranged owing to reason unurgent or that in transportation process, shake, the screw that has can come off, fall in display screen box body the inside, as touch the lamp plate that shows module and can cause short circuit phenomenon; And the client when keeping in repair at the scene screw lose easily.
Summary of the invention
In sum, the present utility model purpose is to solve the problems of the technologies described above, and proposes the fixing screw that shows that module is used of a kind of LED display that can not come off after screw is loosening.
The technological scheme that the technical problem that the utility model proposes for solution adopts is: the fixing screw that shows that module is used of LED display, and comprising: screw rod and nut is characterized in that: also include an adapter sleeve; Be provided with the hollow cavity of an accent in screw rod place direction on described nut, the tail end of screw rod is located at the bottom centre of hollow cavity; Described adapter sleeve is socketed on the screw rod, and an end is located in the hollow cavity in the base of adapter sleeve, and this end is provided with the outer, be provided with on the accent of described hollow cavity with adapter sleeve on the cooperatively interact interior edge of clamping, outer.
As being to the further improved technological scheme of the utility model:
Described adapter sleeve is located at a end outside the hollow cavity and is provided with and tightens up step, described hollow cavity be connected socket in be provided with Returnning spring.
Described nut is a cylindrical body, and its outer wall is provided with anti-skidding line.
The beneficial effects of the utility model are: an end of adapter sleeve of the present utility model is fixed on the module fixed plate of casing by the mode of pressing, before fixing demonstration module, even screw rod is not tightened, can not come off when being in releasing orientation yet, compare with normal screws, when fixedly connected demonstration module, also without the look round for screw, easy to use, increase work efficiency.

Embodiment
Below in conjunction with accompanying drawing and preferred specific embodiment structure of the present utility model is further described:
Shown in seeing figures.1.and.2, the utility model includes: screw rod 1, nut 2, adapter sleeve 3 and Returnning spring 4.Nut 2 is provided with a hollow cavity 21, and the accent of hollow cavity 21 is located at the front end of nut 2, that is to say an end at screw rod 1 place, and the tail end of screw rod 1 is located at the bottom centre of hollow cavity 21, with nut 2 be an overall structure.Adapter sleeve 3 is socketed on the screw rod 1, the tail end of adapter sleeve 3 is located in the hollow cavity 21, the tail end of adapter sleeve 3 is provided with the outer 31 of circle volume outside adapter sleeve 3 outsides, be provided with on the accent of hollow cavity 21 with adapter sleeve 3 on outer 31 the interior of clamping that cooperatively interact along 211, avoided nut 2 and adapter sleeve 3 to break away from.Adapter sleeve 3 front ends, that is to say that an end of being located at outside the hollow cavity 21 is provided with tightens up step 32, purpose is with contraction adapter sleeve 3 front end nozzle diameters, make the pipe outer wall form the step of indent, inner tube wall forms raised step, during Returnning spring 4 is located at hollow cavity 21 and is connected socket 3, the two ends of Returnning spring 4 withstand at the bottom of the chamber of hollow cavity 21 and adapter sleeve 3 tighten up step 32.
Shown in Fig. 2, Fig. 3 and Fig. 4, when the utility model uses, adapter sleeve 3 is fixed on by the mode of pressing in the corresponding aperture position on the module fixed plate 4 of casing, after showing that module 5 is in place, promote nut 2 reaches, Returnning spring 4 compressions, adapter sleeve 3 tail ends direction at the bottom of the chamber of hollow cavity 21 moves into, screw rod 1 stretches out to adapter sleeve 3 front ends, aims at screw hole 51 insertions that show on the module 5 and tightens.The utility model does not influence on the basis of the original fastening function of screw the improvement of normal screws, when dismounting or non-tightening state, can not come off from module fixed plate 4, avoids losing and falling into the infringement that causes LED display in the casing.
