[0035] In the preferred embodiment, the first fixed frame set 1 comprises a first horizontal bar 11, a plurality of slide bar support units 12 inserted into one end of the first horizontal bar 11, and a first connecting rod 13 fixed to the other end of the first horizontal bar 11. Each of the slide bar support units 12 comprises a sliding block a2 slidably mounted on a slide bar a1. Specifically, a plurality of rollers a3 forming a first channel are mounted in each of the sliding blocks a2, the slide bar a1 penetrates through the first channel and is in rolling connection with the rollers a3, and a plurality of first recesses a11 are formed on the side edges of each of the slide bars a1, and a boss a31 is formed on each of the two ends of each of the rollers a3, and each of the bosses a31 abuts against the first recess a11. The first recess a11 and the boss a31 matching the first recess a11 are formed, which effectively reduces the friction coefficient between the slide bar a1 and the rollers a3, reduces the sliding resistance, and effectively prolongs the service life of the product. In some other embodiments, the first connecting rod 13 can not be provided.

[0036] The second fixed frame set 2 is hingedly connected to the other end of the slide bar support unit 12 and the first connecting rod 13. Specifically, the second fixed frame set 2 comprises a second horizontal bar 21, and a plurality of second connecting rods 22 inserted into one end of the second horizontal bar 21 and hingedly connected to the other end of the slide bar a1 and the first connecting rod 13.

[0037] The bidirectional brake module 3 comprises a barrel 31 abutting on two sliders a2, a handle 32 arranged on the barrel 31, and a spring brake wire unit 33 having one end connected with the handle 32 and the other end penetrating into the barrel 31 and correspondingly clamping and positioning / loosing the slide rod a1 controlled by the handle 32. Specifically, the spring brake wire unit 33 comprises brake wires 331 having one end connected with the handle 32, brake needles 332 penetrating into the barrel 31 and connected by the brake wires 331, elastic members 333 sleeved on the outer circumferential side of the brake needles 332 and clamped and positioned by a limiting ring b1 on the brake needles 332, and top pins 334 penetrating a sliding groove of the brake needles 332 and limiting the elastic members 333 together with the limiting ring b1. The slide rod a1 has a plurality of clamping through holes formed on the side edges, and the brake needles 332 are correspondingly clamped into the clamping through holes. Specifically, the barrel 31 comprises a barrel main body c1 having a hollow structure and open ends, fixed shell groups c2 arranged on both ends of the barrel main body c1 and combined to form clamping cavities, and a limiting block c3 clamped and positioned on the open end of the barrel main body c1 and sleeved by the fixed shell groups c2. The limiting block c3 is a semi-cylindrical body with one end partially hollowed out and a limiting ring protruding outward on the other end and abutting and positioning on the outer side of the open end of the barrel main body c1. The middle part of the other end of the limiting block c3 is formed with a passageway, and the passageway is clamped with a first fixed sleeve c31 and a second fixed sleeve c32 clamped and connected with the first fixed sleeve c31 and extending outward of the limiting block c3. The brake wires 331 are connected with the brake needles 332 in sequence through the second fixed sleeve c32 and the first fixed sleeve c31.

When the external force is removed, the elastic members 333 elastically recover and reset the brake needles 332, so that the brake needles 332 are clamped into the corresponding clamping through holes of the slide rod a1 to fix the wind resistance frame.Further, the handle 32 is provided with a first fixing seat 321 at one end, a handle fixing connecting seat 322 wrapping the first fixing seat 321 and fixing the bobbin 31, a fixing seat 323 screwed into the handle fixing connecting seat 322 through a gasket at one end, and a double-channel sleeve partially fixed to the other end of the fixing seat 323 and formed with two channels; two brake lines 331 are correspondingly wound and fixed to the fixing part in the first fixing seat 321.

[0038] The working principle of the present application is as follows: pressing the handle 32, the brake lines 331 are linked with the handle 32, and the corresponding brake needles 332 are pulled respectively, the limiting ring b1 and the ejector pin 334 compress the elastic member 333 during the movement of the brake needles 332, so that the ejector pin 334 is released from the clamping action with the slide rod a1, at this time, the sliding block a2 is pushed to slide along the slide rod a1, and the handle 32 is released when it reaches the desired position, at this time, the two brake needles 332 are clamped into the slide rod a1 respectively to achieve the effect of clamping and fixing, which is simple and convenient to operate.

[0039] As can be seen from the above description, the wind resistance frame of the present application can realize the function of simultaneously controlling the opening or locking of the double-direction brake module 3 through the design of the slide rod support unit 12 cooperating with the double-direction brake module 3, the structure design is ingenious and reasonable, and the efficiency during use is effectively improved, which has quite good effect on the transportation of the product to outdoor and large stage construction.
