technical field

The invention relates to a bracket, which belongs to the field of outdoor sports equipment.

Background technique

At present, there is no special bracket that can be easily adjusted on the market. Only the skeleton support is generally used to achieve its effect, and smarter adjustment cannot be achieved. The disadvantages of them are first of all that they cannot be easily disassembled, and the construction is cumbersome. Complicated terrain, secondly, it is inconvenient to store and carry, and its function is relatively simple, which cannot well meet the functional needs of people in camping life. In addition, ordinary brackets cannot meet the requirements of adjusting heights according to different people's heights. Low, in the end, ordinary brackets are likely to cause more potential safety hazards, which pose a great threat to people's life safety and property safety. Our main purpose is to use a rotary ball valve device that can be rotated and locked at any angle. It can do some folding and angle changes that ordinary brackets cannot complete. At the same time, the telescopic rod can be used to solve the problem of height adjustment. The disadvantages of the brackets are that ordinary brackets lack the characteristics of high efficiency, convenience, intelligence, and multi-functions, which makes it very inconvenient for people to travel outdoors, and even poses certain safety hazards. Therefore, it is necessary to design a bracket to make people travel more at ease and safely, thereby reducing the potential safety hazards caused by the impact, ensuring people's safe travel and increasing fun.

The working principle of the present invention is:

When the bracket needs to be used, the sawtooth mouth 12 and the knife edge 13 can be inserted into the ground to fix the fixed fork; the sawtooth mouth 12 and the knife edge 13 on both sides of the fixed fork are convenient for cutting ropes and bushes, weeds, and ear claws 14 in their camping life Easy rope climbing.

When we are at different heights, we can adjust the fixed valves between the 8 sections of the telescopic rod height adjustment mechanism to achieve the height requirements we want, and expand the activity space longitudinally to complete our own intelligent adjustment. When we don't need the bracket, we can shrink it in the following way, loosen the first telescopic rod fixed valve 25, the second telescopic rod fixed valve 30, the third telescopic rod fixed valve 35, and the fourth telescopic rod fixed valve respectively. Fix the valve 40 with the first telescopic rod, force the top of the first telescopic rod gasket 23 against the second telescopic rod gasket boss 29 (the second telescopic rod gasket boss 29 is located on the first telescopic rod gasket 23 inner side), the second telescopic rod spacer 28 against the third telescopic rod spacer boss 34, the third telescopic rod spacer 33 against the fourth telescopic rod spacer boss 39, while the first telescopic The rod 21 shrinks into the second telescopic rod 26, the second telescopic rod 26 shrinks into the third telescopic rod 31, the third telescopic rod 31 shrinks into the fourth telescopic rod 36, and the fourth telescopic rod 36 shrinks into the fourth telescopic rod. Five joint telescopic rods 41, then tighten the first joint telescopic rod fixed valve 25, the second telescopic rod fixed valve 30, the third telescopic rod fixed valve 35, the fourth telescopic rod fixed valve 40, and finally Shrink the legs.

When we have a demand for the space in the leg, we can stretch the U-shaped groove card 43 outward and at the same time, after selecting a suitable angle, push the U-shaped groove card 43 inward to be stuck on the four-corner fixed valve 45 to meet our own requirements. The horizontal expansion of the internal space achieves more intelligent adjustment.

When we need to adjust the height of the support rod, the second support rod fixing valve 48 is unscrewed, the second support rod 52 is received into the first support rod 47, and the first support rod fixing valve 46 can also be rotated Loosen, shrink the first support rod 47 downwards, so as to achieve the effect of adjusting the height of the support rod.

When the bracket is not needed, the bracket is folded, that is, unscrew the first section of the telescopic rod fixing valve 25 to shrink the first section of the telescopic rod 21 into the second section of the telescopic rod 26, then unscrew the second section of the telescopic rod fixing valve 30, and put the first section of the telescopic rod The second-section telescopic rod 26 shrinks into the third-section telescopic rod 31, similarly unscrew the third-section telescopic rod fixing valve 35 to shrink the third-section telescopic rod 31 into the fourth-section telescopic rod 36, and finally unscrew the fourth-section telescopic rod The fixed valve 40 shrinks the fourth joint telescopic rod 36 into the fifth joint telescopic rod 41, and the adjustable leg one 1, the adjustable leg two 2, the adjustable leg three 3, and the adjustable leg four 4 contract simultaneously; the second joint is supported The rod fixing valve 48 is unscrewed, and the second support rod 52 is retracted into the first support rod 47. At the same time, the first support rod fixing valve 46 can also be unscrewed, and the first support rod 47 is contracted downward; Reduced to achieve the purpose of portability.

The bracket can be used for the support of tents, awnings, rain cloths, cameras and the like.

Four apertures of the four-ear fixed head 53 are used to pass the strings that are tied with the rain cloth, and can cooperate with the support leg fixing mechanism 6 to avoid rope entanglement and reach the effect of fixing the rain cloth.

For the fixing of the camera, there is generally a screw hole below the camera, through which the fixing bolts are inserted into the screw holes to pass through the second support rod 53 and resisted by the four-ear fixing bolts 54 .

The beneficial effects of the present invention are:

1. It can adjust the insertion direction of the fixed fork at multiple angles, change the height under different requirements, protect people and property from the sun and rain at the same time, and can be easily folded and shrunk into a small part when not in use, which is easy to carry and can effectively avoid changes due to terrain , and the change of wind direction in rainy days causes the tent to tilt and people get wet, which leads to accidents that should not happen, ensuring the safety of camping in sunny and rainy days;

2. It can be easily disassembled and used as a harpoon, camera bracket, and the fixed fork can be used as a dagger for self-defense in the wild, realizing multi-function;

3. It can adjust the height of the canopy according to the height of the rider, and the activity is improved. In various weathers, the tent can be intelligently adjusted to avoid collapse, reduce the occurrence of safety accidents, and better protect people's property and personal safety;

4. It enables people to carry and adjust more conveniently, avoids the problems of ordinary camping tents such as large size, difficult to carry, and difficult to disassemble, and brings fun to people's riding life.
