Embodiment
The video camera that anti-transparent cover described in the utility model circles round comprises camera body, camera housing 11, captive screw 12 and translucent cover 13, wherein,
The bottom of camera housing 11 is provided with installs groove 111, support groove 112, tapped through hole 113 and counterbore 114, its concrete structure is as shown in Figure 2: the bottom is provided with at least two grooves 111 is installed, be preferably three, the degree of depth of this installation groove 111 is generally 4mm to 5mm, in order to need with the mode of translucent cover 13 by rotation be installed on this camera housing 11 time be arranged at translucent cover 13 on boss 131 cooperate, cooperate with support groove 112 finally to make boss 131 can pass through this installation groove 111; Each the same side that groove 111 is installed is provided with the support groove 112 that connects with this installation groove 111, the shape of this support groove 112 is complementary with the shape that is arranged at the boss 131 on the translucent cover 13, and (boss 131 can adopt the annular shown in the figure, also can adopt other multiple shapes, as square, irregular polygon etc., the shape of support groove 112 is corresponding with the shape of boss 131, and the specification of support groove 112 is slightly larger than the specification of boss 131, and rear boss 131 can enter support groove 112 so that translucent cover 13 rotates to an angle; In addition, sealing away from the end that groove 111 is installed of support groove 112 circled round in order to avoid translucent cover 13 produces by this end); Camera housing 11 bottoms also are provided with wherein at least one is installed the counterbore 114 that groove 111 intersects (groove 111 is installed can be any with the intersecting angle of counterbore 114, but as long as satisfy the condition that is installed on captive screw 12 free falls in the counterbore 114, optimum way is square crossing), and this counterbore 114 is near support groove 112, the degree of depth of counterbore 114 is not less than the length sum of the thickness of head of screw of captive screw 12 and the leading portion screw thread of captive screw 12 (near the head of screw part), and on counterbore 114 tops, being provided with a tapped through hole 113, the screw thread specification is consistent with the specification of captive screw 12.
As shown in Figure 5, captive screw 12 is provided with the two sections screw threads 121 that are positioned at two ends and is positioned at middle ring groove 122, the length of ring groove 122 accounts for 1/2 of original thread part total length, and be approximately 2.5 to 3 times of tapped through hole 113 degree of depth, the external diameter of this ring groove 122 is less than the path of screw thread.
In the present embodiment, captive screw 12 is screwed into the tapped through hole 113 of camera housing 11, and makes ring groove 122 just fall into tapped through hole 113, captive screw 12 can 113 li of tapped through holes move up and down and not can from or under deviate from.
In addition, above-mentioned tapped through hole 113 can be by press, mold insert or alternate manner is fixed on the camera housing 11, can also be by one-body molded to camera housing 11, or be from the tapping hole.
The concrete steps of installing are: need only the installation groove 111 with 131 alignment housings 11 of the boss on the translucent cover 13, on postpone, boss 131 is captive screw 12 top upwards, after entering counterbore 114 and putting in place, with translucent cover 13 rotations one low-angle, boss 131 just enters support groove 112 fully again.At this moment, captive screw 12 is because of the action of gravity free fall, and it is static to be blocked the back by back segment screw thread 121, promptly installs.At this moment, captive screw 12 has played the effect that stops that translucent cover 13 circles round, as shown in Figure 4.
The concrete steps of dismounting are: with bottle opener the head of screw that captive screw 12 upwards screws in up to captive screw 12 is sunk in the counterbore 114 fully, translucent cover 13 is screwed out in the other direction again; After taking off translucent cover 13, again captive screw 12 is screwed out.
Above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, only the utility model is had been described in detail with reference to preferred embodiment, captive screw and tapped through hole also can adopt other execution modes, as long as guaranteeing this anti-unit that circles round can move up and down freely by tapped through hole or other through holes that is arranged on the shell, and its top can be inconsistent with the upper side of this tapped through hole, its underpart can prevent that boss from circling round towards the direction that groove is installed and get final product, so only otherwise break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of the claim scope of the present utility model.
