Abstract
The utility model relates to the athletic sports apparatus technology, in particular to the main frame welding structure of a jump bed in gymnastics shaping exercise. The main frame pipe and the bearing pipes of the utility model are connected by welding. A flake stiffener is welded on the welded joint of the main frame pipe and the bearing sleeve pipe at the same time, which is square and provided with a hole at the center. The around part of flake stiffener and the central hole are welded at one time and therefore strengthen largely the stiffness of the welding structure. The structure adopted in the utility model means that the welded part is provided with two fixing surfaces, therefore the welding stiffness is strengthen to guarantee the security of the jump bed.
Description
Technical field:
The utility model relates to the athletic sports appliance technical field, the trampoline body frame Welding Structure that particularly a kind of gymnastics body building is used.
Background technology:
Trampoline places a plurality of flexible members of annular frame inside to tighten the formations such as spring face that the back is formed generally by the synthetic annular frame of a plurality of steel pipe, and spring face constitutes a location height by a plurality of foot rests.In the prior art, have the U of employing type folder to be connected between the body frame pipe that constitutes spring face and the supporting sleeve, this connected mode quite expends man-hour, cost, and gets loose easily; The employing Type of Welding is also arranged, Chinese patent provides a kind of trampoline safety fences guard bar joint construction for No. 2571421, be that peripheral frame, foot rest and guard bar are welded to connect, because fender rod, foot rest, peripheral frame all are hollow tube, therefore the problem of burning appears in the joint construction of welding easily in manufacturing process, produce the impaired or material in junction and scrap, also influenced the intensity that engages simultaneously greatly.
The utility model content:
The purpose of this utility model is to overcome the unstable shortcoming of structure in the prior art, and a kind of reliable and stable Welding Structure is provided.
The utility model realizes that the technical scheme that its purpose adopts is: body frame pipe and stay pipe are by being welded to connect, in body frame pipe and supporting sleeve weld, be welded with reinforcing chip simultaneously, reinforcing chip is square, the center offers a hole, weld simultaneously around the reinforcing chip and between the mider hole during welding, strengthen Welding Structure intensity greatly.
After the utility model adopted said structure, promptly being equivalent to weld increased by two stationary planes, can strengthen weld strength like this, guarantees the security of trampoline.
Description of drawings:
Fig. 1 is a schematic diagram before the utility model welding;
Fig. 2 is the utility model welding back schematic diagram.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further specified.
As shown in Figure 1, 2, the utility model comprises body frame pipe 1 and supporting sleeve 2, also comprises reinforcing chip 3, wherein supporting sleeve 2 ends form concave-arc part 21, this concave-arc part 21 can hold just and connects body frame pipe 1 outer surface, earlier the concave-arc part 21 of supporting sleeve 2 is docked with body frame pipe 1 during welding, and welds; Then, at weld position weld reinforcement sheet 3 in the outer part, reinforcing chip 3 centers offer welding hole 30, and centre bore 30 gets final product well with the welding simultaneously all around of reinforcing chip 3 during its welding.
In sum, the utility model is simple in structure, and is convenient and practical.Certainly, the utility model is novel can also be applied to other and have the welding position and have in the structure of strengthening intensity.
