Description
Technical Field
[0001] The utility model relates to the field of positioning brackets, in particular to an automatically telescopic positioning bracket. Background Art
[0002] An automatically telescopic positioning bracket is a support structure with an automatic telescopic function, used for positioning and supporting objects or devices. It usually consists of a telescopic support rod, a positioning component, and a control system.
[0003] With the development of the network, more and more people are used to photographing and recording their lives. Therefore, a variety of selfie sticks have emerged, which are also a type of automatically telescopic positioning bracket. The telescopic mechanism: The automatically telescopic positioning bracket consists of one or more telescopic mechanisms, used to change the length or height of the bracket. The positioning mechanism: The automatically telescopic positioning bracket also includes a positioning mechanism, used to ensure that the object or device is accurately positioned at the required position. The control system: The automatically telescopic positioning bracket is usually equipped with a control system, used to control the operation of the telescopic mechanism and the positioning mechanism.

One end of the spring D24 is fixedly connected to the outer wall of the hinge block B12, and the other end of the spring D24 is fixedly connected to the outer wall of the cylinder B23. By the force of the spring D24, the cylinder B23 is kept moving inwards. There are three groups of support rods 7, and the three groups of support rods 7 are evenly distributed around the rotating shaft 13. The three groups of support rods 7 provide support for the entire bracket 18.
[0035] Working principle: When the automatic telescopic positioning bracket is used outdoors, first pull out the support rod 7 and place it on the ground. Press the wedge block A3 to make the sliding column 2 move upwards with the backing plate 1. Push the sliding column 2 upwards forcefully to make the spring B6 be squeezed and contracted, driving the wedge block B5 to move inwards, so that the sliding column 2 can continue to move upwards. When the outer wall slot of the sliding column 2 moves to the notch of the groove B20, by the force of the spring B6, the wedge block B5 is pushed to be clamped with the slot, achieving the purpose of fixing the position. If it is used outdoors, after pulling out the support rod 7 and placing it on the ground, press the wedge block B5 to make the slot on the outer wall of the sliding column 2 be clamped with the wedge block A3 to fix the position and make the backing plate 1 provide a supporting effect.
[0036] After fixing the bottom support, first press the column A15 forcefully. By pressing the column A15 forcefully, the spring C22 is compressed, causing the column A15 to move towards the inner wall of the groove C21. Then rotate the rotating shaft 13 so that the side of the outer wall of the rotating shaft 13 with the round hole 14 disengages from the insertion of the column A15. At this time, because there is no round hole 14 on the outer wall of the rotating shaft 13, the outer wall of the rotating shaft 13 will continue to press the spring C22, keeping the column A15 moving towards the inner wall of the groove C21, achieving the effect that when the telescopic rod 16 extends or retracts upward or downward, it is not affected by the column A15. Wait until the column B23 is inserted into the round hole 14 to fix the rotating shaft 13 so that it will not rotate when the telescopic rod 16 rises and falls. After that, start the telescopic motor 11 and use the telescopic motor 11 to drive the telescopic rod 16 to move up and down to the required position. First, rotate the rotating shaft 13 so that the round hole 14 on the outer wall of the rotating shaft 13 is inserted into the column A15 to achieve the effect of fixing the current position, and then turn off the telescopic motor 11.
[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
