Abstract
The utility model provides a kind of screw not dropping structure, comprise box body wall, screw locking cover and half screw, described screw locking cover in a tubular form, it has inlet end and convex edge end, described inlet end is provided with fixed hole, described convex edge end is provided with the convex edge of outwards turnover, described half screw has screw head, smooth section and thread section, the external diameter of described thread section is greater than the external diameter of smooth section, the external diameter of described smooth section and the internal diameter of fixed hole suitable, described thread section is positioned at screw locking cover, described screw head is positioned at the outside of inlet end, described box body wall is provided with mounting hole, described screw locking is enclosed within mounting hole place and is fixedly connected with box body wall.Due to the external diameter of smooth section and the internal diameter of fixed hole suitable, make screw lock cover can pin half screw, even if unload lower nut, half screw also can not come off from box body wall, and the service work contributed to when display modular breaks down is carried out smoothly.The splicing that the utility model can be applicable to LED display is installed.
Description
Technical field
The utility model relates to LED display package technique field, particularly a kind of screw not dropping structure.
Background technique
Common LED display is spliced by multiple display modular, and each display modular comprises LED board, casing and electronic component.Be fastenedly connected by screw and nut between existing LED board and casing, need removable screw and nut to overhaul when display modular breaks down, these screw and nuts are probably lost in disassembly process.
Model utility content
For the deficiencies in the prior art, the utility model provides a kind of screw not dropping structure, and this structure can avoid the situation losing screw in the time appearance of overhauling display modular.
The technological scheme of the utility model technical solution problem is as follows:
A kind of screw not dropping structure, comprise box body wall, screw locking cover and half screw, described screw locking cover in a tubular form, it has inlet end and convex edge end, described inlet end is provided with fixed hole, described convex edge end is provided with the convex edge of outwards turnover, described half screw has screw head, smooth section and thread section, the external diameter of described thread section is greater than the external diameter of smooth section, the external diameter of described smooth section and the internal diameter of fixed hole suitable, described thread section is positioned at screw locking cover, described screw head is positioned at the outside of inlet end, described screw head is connected by the smooth section through fixed hole with thread section, described box body wall is provided with mounting hole, described screw locking is enclosed within mounting hole place and is fixedly connected with box body wall.
Screw described in the utility model locking cover is made up of a left side half cover and right half cover, left half cover and rightly partly overlap the plane that contacts and screw locks the axis being parallel overlapped.
Mounting hole periphery described in the utility model is provided with the heavy stand suitable with convex edge.
Beneficial effect described in the utility model is:
Due to the external diameter of smooth section and the internal diameter of fixed hole suitable, make screw lock cover can pin half screw, even if unload lower nut, half screw also can not come off from box body wall, and the service work contributed to when display modular breaks down is carried out smoothly.The splicing that the utility model can be applicable to LED display is installed.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described.Obviously, described accompanying drawing is a part of embodiment of the present utility model, instead of whole embodiment, and those skilled in the art, under the prerequisite not paying creative work, can also obtain other design proposals and accompanying drawing according to these accompanying drawings.
Fig. 1 is complete section figure of the present utility model;
Fig. 2 is the close-up schematic view at A place in Fig. 1.
Embodiment
Be clearly and completely described below with reference to embodiment and the accompanying drawing technique effect to design of the present utility model, concrete structure and generation, to understand the purpose of this utility model, characteristic sum effect fully.Obviously; described embodiment is a part of embodiment of the present utility model, instead of whole embodiment, based on embodiment of the present utility model; other embodiments that those skilled in the art obtains under the prerequisite not paying creative work, all belong to the scope of the utility model protection.In addition, all connection/annexations mentioned in literary composition, not singly refer to that component directly connects, and refer to and according to concrete performance, can connect auxiliary by adding or reducing, and form more excellent connecting structure.Each technical characteristics in the invention, can combination of interactions under the prerequisite of not conflicting conflict.
As illustrated in fig. 1 and 2, a kind of screw not dropping structure, comprise box body wall 1, screw locking cover and half screw, described screw locking cover in a tubular form, it has inlet end 21 and convex edge end 22, described inlet end 21 is provided with fixed hole, described convex edge end 22 is provided with the convex edge of outwards turnover, described half screw has screw head 31, smooth section 32 and thread section 33, the external diameter of described thread section 33 is greater than the external diameter of smooth section 32, the external diameter of described smooth section 32 and the internal diameter of fixed hole suitable, described thread section 33 is positioned at screw locking cover, described screw head 31 is positioned at the outside of inlet end 21, described screw head 31 is connected by the smooth section 32 through fixed hole with thread section 33, described box body wall 1 is provided with mounting hole, described screw locking is enclosed within mounting hole place and is fixedly connected with box body wall 1.The inlet end 21 of described screw locking cover and convex edge end 22 lay respectively at the both sides of box body wall 1, because mounting hole cannot be passed through in the convex edge of convex edge end 22, and the diameter of screw head 31 is also greater than mounting hole, half screw is made not have the cooperation of nut also can stably reside on box body wall 1 in time.
Be further used as preferred embodiment, described screw locking cover is made up of a left side half cover and right half cover, left half cover and rightly partly overlap the plane that contacts and screw locks the axis being parallel overlapped.Due to the internal diameter of fixed hole and the external diameter of smooth section 32 suitable, and the external diameter of smooth section 32 is less than the external diameter in thread section 33, so screw locking cover is preferably formed by more than one piece assembling components.
Be further used as preferred embodiment, described mounting hole periphery is provided with the heavy stand suitable with convex edge.
Above better embodiment of the present utility model is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modifications or replacement under the prerequisite without prejudice to the utility model spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
