In addition, the technical features of the different embodiments of the utility model described later can be combined with each other as long as they do not collide with each other.
Referring to fig. 1-4, an embodiment of the present utility model provides a connection structure between housings, which includes a lower housing 200 having a rectangular cavity and an upper housing 201 for accommodating an adapter, wherein the lower housing 200 and the upper housing 201 can be made of galvanized steel sheets. The end surface of the lower case 200 is provided with a first locking portion, a second locking portion, and a third locking portion, and the end surface of the upper case 201 is provided with a locking hole 205, a bayonet 206, and a locking groove 207. Foam 208 is disposed on the lower housing 200, and the foam 208 is waterproof foam. The upper shell 201 is fastened to the clamping hole 205 through the first locking part, the second locking part compresses tightly the bayonet 206, the third locking part is fastened to the clamping groove 207, and is simultaneously installed on the end face of the lower shell 200 in a locking mode and compresses tightly the foam 208, so that the case and the upper shell 201 are convenient to assemble and disassemble, welding is not needed, and the anti-theft requirement and the waterproof requirement of a product are met.
Specifically, the first locking portion is a limit post 202, and a top portion of the limit post 202 is formed as a limit ring 209. The limiting posts 202 are cylindrical, and the limiting posts 202 are symmetrically arranged on the end surface of the lower housing 200. The limiting post 202 may be a rivet, and the bottom end of the limiting post 202 is riveted and fastened to the lower housing 200. The spacer 209 is a spacer, a threaded hole (not shown) is formed at the top end of the spacer post 202, and the spacer can be fastened and mounted at the top end of the spacer post 202 by a screw. The catching holes 205 are formed as gourd-shaped variable aperture through holes, and the catching holes 205 are symmetrically provided at the bottom surface of the upper case 201. The large end through hole of the clamping hole 205 can pass through the limiting ring 209, and the limiting ring 209 cannot pass through the small end of the clamping hole 205. When the locking hole 205 is locked into the stopper post 202, the upper case 201 can be moved forward and backward in the forward and backward direction by the stopper post 202. When the upper case 201 moves forward, the stopper posts 202 enter the small ends of the catching holes 205, the upper case 201 is restricted from moving up and down by the stopper rings 209, and the stopper posts 202 restrict the upper case 201 from moving left and right. When the upper case 201 moves backward, the stopper post 202 enters the large end of the catching hole 205, the stopper 209 may pass through the large end of the catching hole 205, and the upper case 201 may be detached.
Further, the second locking portion is a double T-shaped card 203, the card 203 is formed with an inclined pressing surface 210, and the bayonet 206 is inserted into the card 203 and pushed along the inclined pressing surface 210, and the card 203 restricts the left-right and up-down movement of the upper case 201. Specifically, the card 203 is provided at an intermediate position of the end face of the lower case 200, and the card 203 may be formed by bending after punching. When the limit post 202 is located at the large end of the card hole 205, the card 203 is not in contact with the bayonet 206, and the upper housing 201 can be detached. When the upper housing 201 is pushed forward, that is, the limit post 202 enters the small end of the card hole 205, the inclined pressing surface 210 on the card 203 abuts against the upper edge of the bayonet 206, and the more the upper housing 201 is pushed forward, the tighter the inclined pressing surface 210 abuts against the bayonet 206, so that the upper housing 201 can be pressed on the lower housing 200, and the movement of the upper housing 201 in the up-down direction is limited. The bayonet 206 holds two cards 203, and the two cards 203 can restrict the movement of the upper case 201 in the left-right direction.
Further, the third locking portion is a locking hook 204, the locking hook 204 is 7-shaped, the locking hook 204 stretches into the clamping groove 207 to tightly clamp the upper shell 201, and the locking hook 204 limits the upper shell 201 to move back and forth and up and down. Specifically, the latch hook 204 may be rotatably installed at a side of the lower case 200 by a lock 211, and the latch hook 204 may be rotated by a key to rotate the lock 211, the lock 211 driving the latch hook 204 to rotate. The latch hook 204 in the rotation limit state can enable the latch hook 204 to pass through the clamping groove 207, and the upper housing 201 can be detached; the latch hook 204 in a released state can be hooked on the upper case 201 to restrict the movement of the upper case 201 in the front-rear and up-down directions, thereby locking the upper case 201.
The above embodiments are only preferred embodiments of the present utility model, and the scope of the present utility model is not limited thereto, but any insubstantial changes and substitutions made by those skilled in the art on the basis of the present utility model are intended to be within the scope of the present utility model as claimed.
