Description

The fastening structure of caravan car light cover

Technical field

The utility model relates to car light, particularly a kind of fastening structure of caravan car light cover.

Background technology

Caravan car light owing to often be in jolt mobile in, being connected between car light cover and the lamp socket must be very fastening, but the syndeton between existing caravan car light cover and the lamp socket, often more open, the time phenomenon that cover comes off can occur slightly for a long time, haves much room for improvement.

The utility model content

The purpose of utility model is to overcome above-mentioned the deficiencies in the prior art part, and a kind of fastening structure of caravan car light cover is provided, and can not only realize being fastenedly connected between cover and the lamp socket, and dismounting is easy, is convenient to safeguard.

For solving the problems of the technologies described above, the technical solution of the utility model is: the fastening structure that a kind of caravan car light cover is provided, the caravan car light comprises columnar lamp socket and circular cover, the bottom of cover is connected with bulge loop, the diameter of bulge loop is less than the diameter of lamp socket cylindrical shell, on the annular region between cover bottom and the bulge loop, be covered with the elastic force cushion rubber, the size of elastic force cushion rubber is lower to corresponding with the lamp socket cylindrical shell; The inwall of lamp socket cylindrical shell is near tube port position, and equidistant intervals is provided with three plush coppers that are stamped to form; The outer wall equidistant intervals of bulge loop is provided with three spill bands, be Intermediate Gray between per two spill bands, be equipped with a fin on each spill band, every fin is all initial from the collar extension edge of bulge loop, upward to extension along the spill band, the afterbody of fin transfers to downward-sloping, and terminal and the Intermediate Gray of fin join; Three plush coppers on three spill bands, are slided to terminal from top along three fins respectively, and fastening is connected with cover with lamp socket.

The fastening structure of aforesaid caravan car light cover on the one side that the elastic force cushion rubber contacts, is evenly distributed with several little hoodles bottom cover, all little hoodles are all one-body molded with the elastic force cushion rubber.

The fastening structure of above-mentioned caravan car light cover, owing to be provided with the fin of three plush coppers and three correspondences, can be by plush copper along fin slip fastening cover and lamp socket, and enclose by elastic plastic and to strengthen fastening effect, thereby can realize preferably being fastenedly connected between cover and the lamp socket, and dismounting is easy, is convenient to safeguard.

The specific embodiment

Referring to Fig. 1, Fig. 2, a kind of fastening structure of caravan car light cover is provided, the caravan car light comprises columnar lamp socket 1 and circular cover 2, the bottom of cover 1 is connected with bulge loop 3, the diameter of bulge loop 3 is less than the diameter of lamp socket 1 cylindrical shell, on the annular region between cover 2 bottoms and the bulge loop 3, be covered with elastic force cushion rubber 4, the size of elastic force cushion rubber 4 is lower to corresponding with lamp socket 1 cylindrical shell.The inwall of lamp socket 1 cylindrical shell is near tube port position, and equidistant intervals is provided with three plush coppers that are stamped to form 5.The outer wall equidistant intervals of bulge loop 3 is provided with three spill bands 6, be Intermediate Gray 7 between per two spill bands 6, be equipped with a fin 8 on each spill band 6, every fin 8 is all initial from the collar extension edge of bulge loop 3, upward to extension along spill band 6, the afterbody of fin 8 transfers to downwards tilting slightly, and the terminal of fin 8 and Intermediate Gray 7 join.

During assembling, bulge loop 3 is inserted in the nozzle of lamp socket 1, two hands are backward rotation lamp socket 1 and cover 2 respectively, three plush coppers 5 are slided to terminal from top along three fins 8 namely respectively on three spill bands 6, and this moment, fin 8 played the effect of serving as " slide rail ", when three plush coppers 5 all slide into the terminal of fin 8, hindered by Intermediate Gray 7, stop to slide, the fastening of lamp socket 1 can being connected with cover connects.In above-mentioned plush copper 5 sliding processes, annular region between 1 time edge of lamp socket and cover 2 bottoms and the bulge loop 3, all elastic force cushion rubber 4 is formed extruding, thus the bounce that elastic force cushion rubber 4 is produced perpendicular to lamp socket 1 and cover 2 directions, thus make the fastening between plush copper 5 and the fin 8 stronger.On elastic force cushion rubber 4 and the one side that cover 2 bottoms contact, be evenly distributed with several submissile pearls 9, all submissile pearls 9 are all one-body molded with elastic force cushion rubber 4, the setting of these submissile pearls 9, in order further to strengthen the bounce of elastic force cushion rubber 4, also can further strengthen the fastening between plush copper 5 and the fin 8, thus make between caravan car light cover 2 and the lamp socket 1 be connected more fastening.

Above-described embodiment is preferred embodiment of the present utility model, and all and the similar structure of the utility model and the equivalence of doing change, and all should belong to protection category of the present utility model.
