DETAILED DESCRIPTION
Technical solutions in embodiments of the present disclosure are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are only some of the embodiments of the present disclosure, but not all embodiments.
Referring to FIG. 1, a bracket 100 may be provided in the present disclosure. The bracket 100 may include a connector 10 and three supporting rods 20 coupled to the connector 10. The connector 10 may be configured to be connected to a photographic device such as a video camera, a mobile phone, or the like.
Referring to FIGS. 2 and 3, the supporting rod 20 may serve as a leg of the bracket 100, and may include a first rod 21, a second rod 22, and a third rod 23. Referring to FIG. 4, a first end of the first rod 21 may define a fixing hole 30, and be connected to the connector 10. A first threaded member 31 may be arranged at a second end of the first rod 21. In this embodiment, the first end may be the top end shown in FIG. 4, and the second end may be opposite to the first end and may be the bottom end in this embodiment. Referring to FIG. 5, at least one second rod 22 may be provided in some embodiments. A second threaded member 32 corresponding to the first threaded member 31 may be arranged at one end of the second rod 22 that is close to the second end of the first rod 21. A third threaded member 33 may also be arranged at the other end of the second rod 22. Referring to FIG. 6, a fourth threaded member 34 may be arranged at a third end of the third rod 23 that is close to the second rod 22, and a fourth end of the third rod 23 that is opposite to the third end may serve as a supporting portion. In some embodiments, the first threaded member 31 and the third threaded member 33 each may be a nut, while the second threaded member 32 and the fourth threaded member 34 each may be a bolt.
In some embodiments, one or more second rods 22 may be selected as required. When using one second rod 22, one end (the top end as shown in FIG. 5) of the second rod 22 may be connected to the first rod 21, and the other end (the bottom end) of the second rod 22 may be connected to the third rod 23. When using a plurality of second rods 22, the plurality of second rods 22 may be successively connected to one another to form an intermediate rod. In this case, the top end of the intermediate rod may be connected to the first rod 21, and the bottom end of the intermediate rod may be connected to the third rod 23.
It should be understood that, the third rod 23 may be directly connected to the first rod 21 without using the second rod 22.
Referring to FIG. 4, the first rod 21 may include a first rod body 211 and a pair of first end pieces 212. The pair of first end pieces 212 may be respectively fixed at two opposite ends of the first rod body 211 along the top-bottom direction. The first threaded member 31 may be disposed on one of the pair of first end pieces 212 (that is, the first end piece 212 at the bottom end), while the other of the pair of first end pieces 212 (the first end piece 212 at the top end) may define the fixing hole 30. A fixing member may pass through the fixing hole 30 and be further connected to the connector 10. In this way, the first rod 21 may be fixed to the connector 10.
Referring to FIG. 5, the second rod 22 may include a second rod body 221 and a pair of second end pieces 222. The pair of second end pieces 222 may be respectively fixed at two opposite ends of the second rod body 221. The second threaded member 32 may be disposed on one of the pair of second end pieces 222 (that is, the second end piece 222 at the top end), while the first threaded member 31 may be disposed on the other of the pair of second end pieces 222 (that is, the second end piece 222 at the bottom end).
Referring to FIG. 6, the third rod 23 may include a third rod body 231 and a pair of third end pieces 232. The pair of third end pieces 232 may be respectively fixed at two opposite ends of the third rod body 231. The second threaded member 32 may be disposed on one of the pair of third end pieces 232 (that is, the third end piece 232 at the top end), and the other of the pair of third end pieces 232 (that is, the third end piece 232 at the bottom end) may serve as a supporting portion.
The first rod body 211, the second rod body 221, and the third rod body 231 may each include an outer sleeve 201 and an inner core 202. The inner core 202 may be fixed in the outer sleeve 201, and two ends of the inner core 202 may be respectively connected to the corresponding end pieces. Optionally, a bottom end of the inner core 202 of the third rod body 23 may be coupled to the third end piece 232 by threaded connection. In this embodiment, the first rod body 211, the second rod body 221, and the third rod body 231 may each be bendable, such that the bracket 100 may be adapted to different environments. In this way, it is possible for the bracket 100 to better cooperate with the photographic device for photography.
Referring to FIG. 7, the connector 10 may include a base 11, a rotatable member 12, and a locking screw 13. The rotatable member 12 may have a connecting screw 121 configured to be connected to the photographic device. The rotatable member 12 may further have a ball portion 122. The base 11 may include a bottom shell 111, an outer shell 112, a fixing member 113, a connecting piece 114, and a fixing screw 115.
Referring to FIG. 8, the bottom shell 111 may support the outer shell 112. The fixing member 113 may be disposed in the outer shell 112. The fixing member 113 may include a fixing portion 1131 and a supporting portion 1132. A groove 1133 may be defined between the fixing portion 1131 and the supporting portion 1132. The connecting piece 114 may be disposed in the bottom shell 111 and connected to the first rod 21. The fixing screw 115 may successively pass through the connecting piece 114 and the bottom shell 111 from the bottom end, and be further connected to the fixing portion 1131, such that the fixing portion 1131 may be relatively fixed to the outer shell 112. A top end of the supporting portion 1132 may be in contact with the ball portion 122. The locking screw 13 may be fixed to a side of the outer shell 112. When screwing the locking screw 13, one end of the locking screw 13 may be received in the groove 1133 and further press the supporting portion 1132. In this way, the fixing member 113 may frictionally lock the ball portion 122, thereby locking an angle of the rotatable member 12.
One side of the outer shell 112 may define a notch 1211. When rotating the rotatable member 12, the rotatable member 12 may be received in the notch 1121, such that the rotatable member 12 may be rotated to a larger angle. In this way, it is possible for the bracket 100 to better cooperate with the photography device for photography.
More specifically, referring to FIG. 9, the end of the locking screw 13 may have an inclined surface 131, and an inclined surface 132 may be defined in the groove 1133. The inclined surface 132 may correspond to the inclined surface 131 of the locking screw 13. When the inclined surface 131 at the inner end of the locking screw 13 is pressed to get into contact with the inclined surface 132 of the groove 1133, the supporting portion 1132 may be deformed to change the contact pressure between the supporting portion 1131 and the ball portion 122, thereby changing the frictional force between the supporting portion 1131 and the ball portion 122. In this way, it is easier to achieve the locking of the angle of the rotatable member 12.
Optionally, a stopping portion 133 may be disposed near the inner end of the locking screw 13. The stopping portion 133 may be configured to prevent the locking screw 13 from being detached from the outer shell 112.
The above embodiments are only some embodiments of the present disclosure, and are not intended to limit the present disclosure. Any modifications, equivalents, and improvements made within the spirit and principles of the present disclosure should be included in the protection of the present disclosure.
