Detailed Description

The present invention will be further explained with reference to the accompanying drawings and examples.

In an embodiment, as shown in fig. 1 and 2, the frame rod connecting piece comprises a clamping hoop 3 and a wedge 4, wherein the clamping hoop 3 is fixedly connected with the female rod 1, and the wedge 4 is matched with the clamping hoop 3 to fixedly connect the sub rod 2 to the clamping hoop 3. The utility model discloses apply clamp 3 and wedge 4 to the connection of vaulting pole, simple structure, the installation of being convenient for, and connect the fastening, improved work efficiency, the cost is reduced.

In an embodiment, as shown in fig. 2 and 3, the clamping band 3 comprises two clamping pieces 301 connected at the lower ends, the upper ends of the clamping pieces 301 are connected with the female rod 1, the lower ends of the two clamping pieces 301 are provided with opposite notches 302, the width of the notches 302 is adapted to the width of the male rod 2, and the height of the notches 302 is greater than the height of the male rod 2. In an embodiment, the female rod 1 passes between the upper ends of the two clips 302, and the clips 302 are fixed on the female rod 1 by screws. The lower end of the clamping piece 302 is provided with a notch 302 for the sub-rod 2 to pass through, and the notch 302 is an open structure, so that the sub-rod 2 is convenient to mount. The width of the notch 302 is adapted to the width of the sub-rod 2, so that the sub-rod 2 cannot shake left and right after being sleeved; the height of the notch 302 is larger than that of the sub-rod 2, so that the sub-rod 2 is sleeved in a space 304 for inserting the wedge 4. In order to fix the sub-rod 2 after being sleeved, the height of the wedge 4 should be adapted to the insertion space 304 so as to insert and clamp the sub-rod 2. In order to make the sub-rod 2 more conveniently sleeved in the notch 302, the width of the through hole 302 can be set to be larger at the bottom and smaller at the top, specifically, the width of the lower end of the notch 302 can be set to be larger than the width of the sub-rod 2, and the width of the upper end of the notch 302 is matched with the width of the sub-rod 2, so that the sub-rod 2 can be conveniently sleeved, and the sub-rod 2 can not shake left and right after being installed.

In the embodiment, as shown in fig. 4, the wedge 4 is inserted into the end lower than the rear end, and the upper surface is a bevel. After the sub-rod 2 is inserted into the notch 302, the wedge 4 is inserted into an insertion space 304 reserved between the two clamping pieces 301 at the lower end. The wedge 4 should be adapted to the insertion space 304 and should have a height suitable for clamping the sub-rod 2 in the recess 302 after insertion. In order to facilitate the insertion of the wedge 4, the wedge 4 is generally disposed such that the insertion end has a height lower than the rear end, and further, the upper surface of the wedge 4 is provided with a smooth slope; and the bottom surface of the wedge 4 is configured to conform to the inner surface of the lower connecting end 303 of the two said jaws 302, and may be configured as a generally conforming arcuate surface.

In an embodiment, as shown in fig. 4 and 5, in order to prevent the wedge 4 from sliding after being inserted in place, a first limiting convex strip 401 is arranged at the rear end of the wedge 4, and a second limiting convex strip 402 is arranged at the insertion end of the wedge 4; in order to prevent the second restriction ridge 402 from obstructing the insertion of the wedge 4, as shown in fig. 5, the side surface of the second restriction ridge 402 is provided with an insertion assisting slope 4021.
