Detailed Description

In order to make the objects, technical solutions and advantageous effects of the present invention more clearly understood, the present invention is further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 to 12, a preferred embodiment of an accessory device for a camera according to the present invention is shown.

The accessory device 100 for a camera in the present embodiment includes a housing, a camera mounting cord 13, a retracting mechanism 14, and a selfie stick holder 16. Wherein the housing comprises in this embodiment a first housing 11 and a second housing 12.

As shown in fig. 2, the camera mounting cord 13 in this embodiment includes a quarter threaded post 131 and a cord body 132, one end of the cord body 132 is fixedly connected to the retracting mechanism 14, and the other end is connected to the quarter threaded post 131 through a cord hole (not labeled in fig. 2) in the housing. The quarter threaded column 131 can also be replaced by a quarter threaded hole, and of course, other connecting pieces can also be used, as long as the camera and the rope body can be connected and fixed. In this embodiment, to prevent the rope 132 and the quarter threaded column 131 from being completely pulled into the housing by the retraction mechanism 14, the diameter of the quarter threaded column 131 may be set larger than the diameter of the rope hole. The string body 132 of the camera attachment string 13 in the present embodiment is a steel wire nylon string, but a general nylon string or a braided string may be used.

As shown in fig. 5 and 6, the first casing 11 forms a recessed space (not labeled) inward, and includes a first casing main body 110, a rope hole 111, a first fixing hole 112 and a positioning post 113, wherein the positioning hole 113 is formed from the bottom of the recessed space, and the positioning post 113 is provided with a groove 113a for fixing the pick-and-place mechanism 14; the outer surface of the first shell 11 is provided with a soft rubber anti-slip pad 16, and the soft rubber anti-slip pad 16 is used for increasing the friction force between the hand of the user and the first shell 11, so that the probability that the user throws away the camera when shooting bullets is reduced.

As shown in fig. 7 and 8, the retraction mechanism 14 in this embodiment has a substantially "i" shape in cross section, and includes an upper edge 141, a lower edge 142, a coil spring 144, and a positioning hole 143. The upper and lower rims 141 and 142 are respectively located at both ends of the retracting and releasing mechanism 14 and have a diameter larger than that of the middle portion of the retracting and releasing mechanism 14, so that the string body 132 of the camera mounting string 13 can be wound between the upper and lower rims 141 and 142, and the lower rim 142 has a height which is inwardly recessed to form a recessed space (not shown) for accommodating the coil spring 144. Coil spring 144 has one end fixed in recess 113a of positioning post 113 and the other end fixed to lower edge 141. The diameter of the positioning hole 143 is slightly larger than the diameter of the positioning post 113 of the first housing 11, and after the positioning hole 143 is installed on the positioning post 113, the pick-and-place mechanism 14 can rotate around the positioning post 113.

As shown in fig. 9 and 10, the second casing 12 in this embodiment includes a second casing main body 120 and a second fixing hole 121, the inner surface of the second fixing hole 121 is provided with a thread 121a, and the outer surface of the second casing 12 is also provided with a soft rubber anti-skid pad 16.

As shown in fig. 11 and 12, the selfie stick fixing member 16 includes a nut 151, a bearing 152, and a screw 153, an outer edge of the screw 153 is threaded to be engaged with a thread 121a in the second fixing hole 121 of the second housing 12, the bearing 152 and the nut 151 in this embodiment are fixed together, and a rear surface of the screw 151 is provided with a quarter threaded hole 151 a. The first and second housings 11 and 12 can be fixed together by engaging the nuts 151 and the screws 153 through the first and second fixing holes 112 and 121. When the rear side of the nut 151 is provided with a quarter screw hole to be fixed to the selfie stick, the accessory device 100 is allowed to rotate about the bearing 152. One skilled in the art can also fix the screw 153 and the bearing 152 together, change the quarter threaded hole on the back of the nut 153 into a quarter threaded post, and so on, with equivalent changes.

The utility model discloses an realize the principle as follows: when the camera safety rope 13 is pulled, the retracting mechanism 14 rotates relative to the shell, the coil spring 144 of the retracting mechanism 14 is stretched and slowly wound on the fixed column 113 when the retracting mechanism 14 rotates, and elastic potential energy is accumulated; when the camera safety rope 13 is released, the elastic potential energy accumulated in the coil spring 144 causes the retracting mechanism 14 to rotate reversely with respect to the housing, so that the camera safety rope 13 is retracted and wound around the retracting mechanism 14.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
