Fig. 3 is the sectional structure chart of the bracing frame pin holes of the utility model one embodiment.
Detailed description of the invention
By describing technology contents of the present utility model, structural attitude in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with embodiment.
As depicted in figs. 1 and 2, the utility model provides a kind of self-stopping runner, comprises bracing frame 1, and be provided with square opening 2 in the middle of bracing frame, square opening runs through bracing frame both sides, and square opening bottom is provided with sliding panel 3, and sliding panel can move up and down in square opening.Be provided with Compress Spring 4 above sliding panel and between square hole wall, sliding panel moves up and can extrude Compress Spring.Sliding panel is provided with axis hole 5, is provided with rotating shaft 6 in axis hole, and the two ends of rotating shaft are provided with wheel cap 7, and the inside of wheel cap is provided with the friction face 8 concentric with wheel cap side face, is provided with the braking vane 9 contacted with friction face on bracing frame and above axis hole.When bracing frame of the present utility model does not have a load, Compress Spring can extrude sliding panel downwards, sliding panel drives wheel cap to extrude braking vane after driving rotating shaft, make wheel cap be subject to friction force and not move, and when bracing frame has load, between bracing frame and wheel cap, have squeese pressure, wheel cap is moved up, thus disengaging braking vane, namely can normally movement, realize self-actuating brake.
In certain embodiments, as shown in Figure 1, described braking vane is arranged on the both sides of square opening.There are two braking vanes the every side of such bracing frame, increases friction force.
In order to reach maximum friction force in equal area, described braking vane is arc, and the peripheral radius of braking vane is identical with the radius of described friction face.When such braking vane contacts with friction face, namely whole face all can contact, and increases friction force.
The utility model does not limit the annexation of runner and carrier, can by being directly fixed on carrier by bracing frame, or as shown in Figure 3, bracing frame is provided with pin holes 10, is provided with contact pin (scheming not shown) in pin holes.Runner can be fixed on carrier by contact pin like this.
In certain embodiments, in order to avoid contact pin rocks, pin holes 10 inwall is provided with the annular protrusion 100 around pin holes.Annular protrusion is preferably arranged on the side near pin holes opening, is filled with the gap between contact pin and pin holes, pin holes and contact pin is fixed together, avoids contact pin and rock, extend the contact pin life-span by annular protrusion.
In certain embodiments, pin holes can be arranged on bracing frame midway location, in order to realize the universal rotational of runner, and the axis runout axis hole center of described pin holes.
In some specific embodiment, support frame as described above comprises top cover 23, and top cover 23 is circular arc type, is arranged on above square opening, and the center of circle of described circular arc is at the center of turn of rotating shaft.Top cover 23 can around wheel cap or top cover between wheel cap, around time, top cover can protect wheel cap to avoid being encountered, and when top cover is between wheel cap, can reduce the height of wheel cap.By above-mentioned design, this runner can use more easily, improves practicality of the present utility model.
In certain embodiments, in order to increase the attachment force of rotating shaft and wheel cap, the two ends of described rotating shaft are respectively equipped with two adjacent circular grooves 40, circular groove twisted rotary shaft side is arranged, be provided with in the axis hole 53 of wheel cap around two of axis hole medial surface adjacent annular bar 54, annular bar is placed in described circular groove.
