Example 1

Referring to fig. 1-6, the present invention provides a technical solution:

the utility model provides a shell structure is moulded to convenient board in a poor light of installing, including board in a poor light main part 1, board in a poor light main part 1 is installed on fixed backshell 2, cavity 21 has been seted up to the positive position department of fixed backshell 2, overlap joint groove 211 has been seted up to the oral area edge of cavity 21, board in a poor light main part 1 all integrated into one piece all around edge department has protruding edge 11, protruding edge 11 overlap joint is in overlap joint groove 211, protruding thickness along 11 is half of board in a poor light main part 1 thickness, the size of overlap joint groove 211 and protruding size looks adaptation along 11, make protruding edge 11 whole can overlap joint inslot 211 and make protruding terminal surface along 11 can flush with board in a poor light main part 1's front mutually. A plurality of studs 22 are installed to the positive outside edge of fixed dorsal scale 2, and the stud 22 endotheca is equipped with a plurality of snap rings 223, is provided with on the front of fixed dorsal scale 2 and covers frame 3, and the back integrated into one piece of lid frame 3 has a plurality of posts 31 of inserting, inserts the periphery of post 31 and has seted up a plurality of draw-in grooves 311 on the surface, inserts post 31 and inserts in the stud 22, inserts post 31 and passes from the snap ring 223, and the peripheral department at draw-in groove 311 is cup jointed to snap ring 223. The side of draw-in groove 311 is personally submitted the conical surface form, be close to on the draw-in groove 311 and insert the terminal tank bottom department of post 31 and be planar, make through will inserting post 31 and insert in the post 22 after aligning with the board main part 1 in a poor light, snap ring 223 can block in draw-in groove 311, under the planar effect of draw-in groove 311, can prevent to insert post 31 and deviate from in the post 22, can prevent to cover frame 3 from droing from fixed backshell 2 when reaching easy to assemble lid frame 3, thereby make board main part 1 in a poor light can be conveniently fixed between fixed backshell 2 and lid frame 3, thereby efficiency when increasing staff's installation board main part 1 in a poor light.

In this embodiment, the cover frame 3 cover is established in the peripheral department of board main part 1 in a poor light and the overlap joint is on protruding edge 11 for board main part 1 in a poor light is inboard by restriction cover frame 3, and when board main part 1 in a poor light was installed between fixed backshell 2 and cover frame 3, the surface of cover frame 3 can keep flushing with the surface of board main part 1 in a poor light simultaneously, increases the whole aesthetic property after board main part 1 in a poor light installs.

Specifically, a plurality of mounting holes 212 have been seted up to the positive outside edge of fixed backshell 2, and the embedded column 22 cover is established in mounting hole 212 and with the mounting hole 212 tight fit, makes embedded column 22 fixed in mounting hole 212, prevents to take place because of the embedded column 22 drops and makes the condition that the lid frame 3 drops from fixed backshell 2 to prevent that board main part 1 in a poor light from dropping.

Furthermore, the top end of the stud 22 is provided with an insertion hole 221, the stud 31 is inserted into the insertion hole 221, the outer surface of the stud 22 is provided with a plurality of through grooves 222, the through grooves 222 penetrate through the side end of the stud 22, and the snap ring 223 is sleeved in the through grooves 222. The snap ring 223 is the loop configuration of waist shape and uses metal to make, make snap ring 223 have certain elasticity, the length of snap ring 223 is less than the external diameter of studded column 22, make the whole logical inslot 222 that can be accomodate of snap ring 223, the width of snap ring 223 is less than the aperture of jack 221, the long limit that makes snap ring 223 can transversely run through jack 221, thereby when making the post 31 of inserting insert in the studded column 22, insert post 31 and can articulate on snap ring 223 through draw-in groove 311, reach the purpose of fixed lid frame 3.

In addition, a guide head 312 is integrally formed at the end of the plug 31, the guide head 312 is in a circular truncated cone shape, when the plug 31 is inserted into the insertion hole 221, the guide head 312 first contacts with the snap ring 223, so that the snap ring 223 is gradually expanded and elastically deformed under the action of the outer surface of the guide head 312, and the plug 31 can be smoothly inserted into the stud 22 and the plug 31 is hung on the snap ring 223 through the slot 311.

The convenient board that carries on installing of this embodiment moulds shell structure when installing, at first put into fixed backshell 2 with the board main part 1 that is shaded after protruding edge 11 and overlap joint groove 211 alignment in board main part 1 periphery department, make board main part 1 overlap joint on fixed backshell 2 in a poor light, then remove lid frame 3 to the front department of fixed backshell 2 and make and insert post 31 and inlay the post 22 and align, make through pressing lid frame 3 at last insert post 31 and insert in jack 221, along with inserting the inserting of post 31, the direction head 312 of inserting the post 31 tip struts snap ring 223, make snap ring 223 warp the back cup joint in the outside of inserting post 31, and make and insert post 31 and articulate on snap ring 223 under the effect of draw-in groove 311, reach the purpose of fixed lid frame 3, thereby can conveniently fix board main part 1 in a poor light between fixed backshell 2 and lid frame 3.

Example 2

In order to conveniently carry out swift field installation work to the fixed dorsal scale 2 of having installed the board main part 1 that backs a sun, as shown in fig. 7 and fig. 8, the side groove 23 has all been seted up to the left and right sides terminal surface department of fixed dorsal scale 2, and threaded connection has a plurality of tight bolts 231 of supporting in the side groove 23, and bedplate 241 inserting groove 24 has all been seted up to the left and right sides edge at the fixed dorsal scale 2 back, has pegged graft bedplate 241 in the inserting groove 24, and the end that supports tight bolt 231 offsets with bedplate 241. The seat plate 241 is a plate-shaped structure with an L-shaped cross section, after the seat plate 241 is fixed on the surface of an object in advance, the inserting groove 24 on the fixing back shell 2 is sleeved on the seat plate 241, and the fastening bolt 231 is screwed at the moment to achieve the purpose of installing the fixing back shell 2, so that the fixing back shell 2 is conveniently fixed on the object.
