Abstract
The utility model discloses a jumping bed frame pipe connecting structure, which comprises a frame pipe, a foot pipe and a three-way piece, wherein the three-way piece is formed by a standpipe and a horizontal pipe which is welded on the upper end of the standpipe, the foot pipe longitudinally passes through the standpipe, the frame pipe extends from two ends into the horizontal pipe and is sheathed with the horizontal pipe, the horizontal pipe forms a locating groove inwardly projected along the length direction, and the frame pipe forms the corresponding locating groove at the connecting end. The structure can not only lead the assembling operation to be quicker, but also the transport and the storage are more convenient after dismantlement, which can simultaneously and effectively enhance the bonding strength, and the phenomena of shaking, slipping or damaging the bonding portion are not easy to occur.
Description
Technical field
The utility model relates to the local linkage structure of trampoline, exactly is the arc frame pipe of trampoline and the linkage structure of pin pipe intersection.
Background technique
Traditional trampoline mainly is made up of parts such as frame pipe, elasticity original paper, spring faces, is provided with foot rest below the frame pipe, the many synthetic circular frames of frame circumferences of cannon bone, and spring face is positioned at framework inside, and its periphery is tightened by the elasticity original paper.Owing to adopt the mode of welding to connect between the frame pipe, therefore can destroy original zinc coat, the welding part gets rusty easily, and antiseptic power is poor, and outside no second layer protection, and structural strength is obviously not enough, easily produces shaking phenomenon, even causes the fracture of tubing.
The model utility content
At the deficiency that prior art exists, the purpose of this utility model is to provide a kind of trampoline frame pipe connecting structure.This structure is convenient to quick assembly and disassembly, and can effectively improve the join strength at frame pipe jointing position.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of trampoline frame pipe connecting structure, comprise frame pipe, pin pipe and the three-way joint element that is connected usefulness, described three-way joint element is made of vertical tube and the transverse tube that is welded on riser upper end, the pin pipe longitudinally penetrates vertical tube, the frame pipe stretches into transverse tube and connects together from two ends, transverse tube is formed with inwardly protruded positioning groove along its length direction, and frame Guan Zaiqi connecting end is formed with corresponding positioning groove.
The positioning groove of described transverse tube connects whole transverse tube.
Leave a determining deviation between the positioning groove two ends of described transverse tube and its end face.
Described transverse tube cross section is square, rectangle or abnormity.
The cross section of described positioning groove is circular arc.
The arc diameter of described positioning groove is 14-18mm, and the degree of depth is 2.5-4.5mm.
Described transverse tube is formed with one or multi-channel positioning groove on its end face.
Described transverse tube is formed with one or multi-channel positioning groove on its side.
Described transverse tube bottom offers corresponding with vertical tube and less than the through hole of its internal diameter.
The utility model is simple in structure, easy to use, only need the pin pipe is inserted the vertical tube of three-way joint element during assembling, again trampoline frame pipe is stretched into transverse tube and is sleeved on together along positioning groove and can finish connection, can not only realize quick assembling, and being convenient to transportation after the dismounting stores, positioning groove can effectively improve adhesive strength, is not easy to produce to rock, skid or make the impaired phenomenon of binding site.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of reference numerals is as follows:
1---the frame pipe
2---the pin pipe
3---vertical tube
4---transverse tube
5,5 '---positioning groove
6---through hole
As Fig. 1, first embodiment shown in Figure 2, this trampoline frame pipe connecting structure is mainly by frame pipe 1, pin pipe 2 is formed with the three-way joint element that is connected usefulness, three-way joint element is made of vertical tube 3 and the transverse tube 4 that is welded on riser upper end, pin pipe 2 longitudinally penetrates vertical tube 3, frame pipe 1 stretches into transverse tube 4 and connects together from two ends, the cross section of transverse tube 4 is square, its end face is formed with inwardly protruded positioning groove 5 together along its length, the cross section of this positioning groove is circular arc, diameter is 14-18mm, the degree of depth is 2.5-4.5cm, and frame pipe 1 is a circular pipe, and its connecting end is through the machine-processed squarely that closes up, suppress corresponding positioning groove then, the bottom of transverse tube 4 offers corresponding with vertical tube 3 and less than the through hole 6 of its internal diameter, so that zinc-plated, operate in the processes such as welding, can also save material simultaneously.Certainly, the quantity of positioning groove and position are decided by factors such as load bearing stength, pipe fitting sizes, and as shown in Figure 3, transverse tube is formed with the twice positioning groove on its end face, or as shown in Figure 4, transverse tube is formed with one positioning groove on its side.In addition, transverse tube also can form one or multi-channel positioning groove or the like on its bottom surface.
As Fig. 5, Fig. 6, second embodiment shown in Figure 7, the positioning groove 5 of its transverse tube ' two ends and its end face between leave a determining deviation, that is to say the positioning groove 5 of transverse tube ' two ends outwards do not slit logically, all the other structures and first embodiment are basic identical, just repeat no more here.Certainly, the quantity of positioning groove and position are decided by factors such as load bearing stength, pipe fitting sizes, as shown in Figure 8, transverse tube on its end face, be formed with twice positioning groove 5 ', or as shown in Figure 9, transverse tube on its side, be formed with one positioning groove 5 ' or the like.
Only need trampoline pin pipe is inserted the vertical tube of three-way joint element during use; again trampoline frame pipe is stretched into transverse tube and is sleeved on together along positioning groove and can finish connection; transverse tube can form double shielding to the connection part of frame pipe; all parts all are fixed; can not freely rotate, improved the robustness and the Security of main body greatly.
The utility model is not limited to above-mentioned preferred forms, and anyone can draw other various forms of products under enlightenment of the present invention.Though but on its shape or structure, do any variation, every identical with the utility model or akin technological scheme is all within its protection domain.
