[0034] See also Figures 1 to 6 A wind resistance frame of this embodiment includes: a first fixed frame group 1, a second fixed frame group 2, a two-way brake module 3 and a group of connecting cross bars 4, and the first fixed frame group 1, the second fixed frame group 2 and the connecting cross bars 3 are assembled into a triangular frame.

[0035] In a preferred embodiment, the first fixed frame group 1 includes: a first horizontal bar 11, a group of slide bar bracket units 12 inserted into the first horizontal bar 11 at one end, and a first connecting rod 13 fixed at one end on the first horizontal bar 11. Each of the slide bar bracket units 12 includes a slider a2 slidably mounted on the slide bar a1. Specifically, a plurality of rollers a3 forming a first channel are installed in each of the sliders a2, the slide bar a1 passes through the first channel and is rollingly connected to the roller a3, and a plurality of first grooves a11 are partially hollowed out on the side of each of the slide bars a1, and a boss a31 is formed at both ends of each of the rollers a3, and each of the bosses a31 abuts against the first groove a11. The formation of the first groove a11 and the boss a31 matching the first groove a11 effectively reduces the friction coefficient between the slide bar a1 and the roller a3, reduces the sliding resistance and effectively increases the service life of the product. In some other embodiments, the first connecting rod 13 may not be provided.

[0036] The second fixing frame group 2 is hinged to the other end of the slide bar bracket unit 12 and the first connecting rod 13. Specifically, the second fixing frame group 2 includes: a second cross bar 21, one end of which is inserted into the second cross bar 21, and the other end of which is correspondingly hinged to the slide bar a1 and a plurality of second connecting rods 22 of the first connecting rod 13.

[0037] The bidirectional brake module 3 includes a tube 31 abutting against the two sliders a2, a handle 32 provided on the tube 31, and an elastic brake line unit 33, one end of which is connected to the handle 32, the other end of which is inserted into the tube 31, and the handle 32 controls the corresponding clamping and positioning / releasing of the slider a1. Specifically, the elastic brake line unit 33 includes: a brake line 331 with one end connected to the handle 32, a brake needle 332 that penetrates through a limit block c3 in the tube 31 and is connected by the brake line 331, an elastic member 333 that is sleeved on the outer peripheral side of the brake needle 332 and is clamped and limited by a limit ring b1 on the brake needle 332, and a top pin 334 that penetrates a sliding groove of the brake needle 332, crosses the elastic member 333 and acts together with the limit ring b1 to limit the elastic member 333. A plurality of snap-in holes are formed on the side of the slide bar a1 , and the brake pin 332 is snap-into the snap-in holes accordingly. Specifically, the barrel 31 includes: a barrel main body c1 with a hollow structure inside and openings at both ends, a fixed shell group c2 installed at both ends of the barrel main body c1 and combining a clamping cavity, and a limit block c3 that is clamped and limited at the open end of the barrel main body c1 and is sleeved by the fixed shell group c2. The limit block c3 is partially hollowed out at one end to be a semi-cylindrical shape, and a limit ring is convexly provided on the end to abut against the outer surface of the open end of the barrel main body c1. An aisle is formed in the middle of the other end of the limit block c3, and a first fixed sleeve c31 is clamped in the aisle, and a second fixed sleeve c32 that is clamped and connected to the first fixed sleeve c31 and extends outside the limit block c3, and the brake line 331 is connected to the brake needle 332 after passing through the second fixed sleeve c32 and the first fixed sleeve c31 in sequence. The limit block c3 and the tube 31 are fixed by a pin d1, specifically, the pin d1 penetrates the tube 31 and is fixed to the groove ring on the outer peripheral side of the limit block c3. The fixed housing group c2 includes: a first housing formed with a second channel and a missing block formed on one end, and a second housing matching the missing block and extending the second channel. Furthermore, the brake needle 332 is clamped on the limit block c3 and connected to the brake line 331, and the ejector pin 334 vertically penetrates the slide groove of the brake needle 332 and the elastic member 333 sleeved on the brake needle 332, and then the two ends thereof are respectively abutted on the fixed housing group c2. When pulling force is applied to the brake needle 332, the limiting ring b1 and the ejector pin 334 interact with each other to compress the elastic member 333, so that the brake needle 332 releases the clamping fixation to the slide bar a1. When the external force is removed, the elastic member 333 elastically recovers and resets the brake needle 332, so that it is clamped into the corresponding clamping hole of the slide bar a1 to fix the windage frame.Furthermore, a first fixing seat 321 is installed at one end of the handle 32, a handle fixing connecting seat 322 that wraps the first fixing seat 321 and fixes the barrel 31, one end of which is screwed into a fixing seat 323 of the handle fixing connecting seat 322 through a gasket, and a double-channel sleeve that is partially fixed to another section of the fixing seat 323 and is formed with two channels; two brake lines 331 are wound and fixed to the fixing part in the first fixing seat 321 after corresponding to the two channels.

[0038] The working principle of the present invention is: the handle 32 is pressed, the brake line 331 is linked with the handle 32 to pull the corresponding brake pin 332 respectively, and during the movement of the brake pin 332, the limit ring b1 and the ejector pin 334 act on the elastic member 33 to compress the elastic member 333, so that the ejector pin 334 releases the clamping effect with the slide bar a1. At this time, the slide bar a2 is pushed to slide along the slide bar a1, slide to the required position and then release the handle 32. At this time, the brake pins 332 at both ends are respectively clamped into the slide bar a1 to achieve the effect of clamping and fixing, and the operation is simple and quick.

[0039] From the above description, it can be seen that a wind resistance frame of the present invention, by designing the sliding rod bracket unit 12 to cooperate with the two-way brake module 3, enables this product to realize the function of controlling the two-way opening or locking at the same time with one handle 32. The structural design is ingenious and reasonable, which effectively improves the efficiency during use and has a very good effect on transporting the product to the outdoors and building large stages.
