CN202416987U - Connecting structure for tent joint and pipe fittings - Google Patents

Abstract

The utility model discloses a connecting structure for a tent joint and pipe fittings, wherein the joint is connected between two pipe fittings of a tent supporting rod and is provided with joint ends inserted into ends of the pipe fittings. A screw hole and a through hole are respectively arranged on a portion of each joint end inserted into the corresponding end of the pipe fittings, the position of the screw hole is opposite to that of the through hole, and a screw penetrates through each through hole and is screwed into the corresponding screw hole to connect the through hole with the screw hole. The sections of the outer walls of the joint ends and the sections of the inner walls of at least the ends of the pipe fittings are non-circular. By the aid of the non-circular structure, when the pipe fittings or the joint ends are stressed, the pipe fittings and the joint ends can synchronously rotate. Therefore, when a tent support is folded, torsion applied to the supporting rod can be smoothly transferred to pipe bases and finally eliminated, and the service life of the supporting rod can be prolonged.

Description

The syndeton of tent joint and pipe fitting

Technical field

The utility model relates to a kind of tent accessory, refers to the syndeton of a kind of tent joint and pipe fitting especially.

Background technology

Present tent all adds tarpaulin by tent bracket and forms; As shown in Figure 1; Tent bracket generally all includes some poles 1; The top of each pole 1 is articulated through a backform piece 2 each other, and each root pole 1 is formed by at least two pipe fittings 11 again, then links together through joint 12 between each pipe fitting 11.Each pipe fitting 11 of existing tent and the syndeton between the joint 12 are like Fig. 2, shown in 3; The ball and socket joint 121 in this joint 12 inserts in the end of said pipe fitting 11; The part that both peg graft each other is respectively equipped with position relative screw 122 and through hole 111, with a screw 13 both is linked together afterwards.Because the inwall of described ball and socket joint 121 outer walls and pipe fitting 11 is circle, both meetings are rotated relatively, when pipe fitting 11 stressed the reversing of top; Joint 12 will receive reaction force, like this, and when the tent bracket folding; The active force of the downward folding of support conducts to pole 1 bottom by pipe fitting 11 and joint 12; But, therefore can produce with joint 12 pipe fitting 11 and destroy, so that product can't normally use at screw 13 places because moment produces the torsion of different directions after via the joint.

The utility model content

The utility model technical problem to be solved is to provide the syndeton of a kind of tent joint and pipe fitting, and it can guarantee tent pole in the stressed unanimity of joint, to increase application life.

For solving the problems of the technologies described above, the technical solution of the utility model is:

The syndeton of a kind of tent joint and pipe fitting; Said joint is connected between two pipe fittings of tent pole; This joint is provided with ball and socket joint; This ball and socket joint inserts in the end of this pipe fitting, and the part that both peg graft each other is respectively equipped with relative screw in position and through hole, and a screw passes the through hole spiral shell and in screw, both linked together; Described ball and socket joint outer wall cross section and described the pipe fitting inner wall section in its end at least are non-circular.

Described ball and socket joint outer wall cross section and described the pipe fitting inner wall section in its end at least are D shape.

Described ball and socket joint outer wall cross section and described the pipe fitting inner wall section in its end at least are square, triangle or pentagon.

After adopting such scheme; Because the ball and socket joint in the said joint of the utility model and the face of cooperatively interacting of pipe fitting are non-circular, when pipe fitting or ball and socket joint are stressed, can make both rotate synchronously, like this when pipe fitting is stressed; The joint can be stressed in the same way with it; Therefore tent bracket is when folding, and the torsion that pole is produced can conduct to pin pipe place and final the elimination smoothly, thereby can increase the application life of pole.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to detail.

What the utility model disclosed is the syndeton of a kind of tent joint and pipe fitting, like Fig. 4 and shown in Figure 5, cooperates Fig. 1 simultaneously.Said joint 12 is connected between two pipe fittings 11 of tent pole; This joint 12 is provided with ball and socket joint 121; This ball and socket joint 121 inserts in the end of this pipe fitting 11; The part that both peg graft each other is respectively equipped with position relative screw 122 and through hole 111, one screws 13 pass through hole 111 spiral shells in screw 122, thereby both are linked together.

The key of the utility model is: described ball and socket joint 121 outer wall cross sections are D shape, and described pipe fitting 11 inner wall section in its end at least also is a D shape.Because ball and socket joint 121 is a D shape with the face of cooperatively interacting of pipe fitting 11; Can make both rotate synchronously, like this when pipe fitting 11 is stressed, joint 12 can with one of which with stressed; Thereby can the fine pin pipe place that conducts to of active force also finally be eliminated, and then can increase the application life of pole.

In fact; As long as the contact portion cross section that makes said ball and socket joint 121 and pipe fitting 11 peg graft each other is non-circular; For example square, triangle, pentagon or the like; Rotate synchronously in the time of all can making both stressed, tent bracket is when folding like this, and the torsion that pole is produced can conduct to the elimination of pin pipe place smoothly.Certainly, be the embodiment of D shape for above-mentioned cross section, the cross section of D shape is one of a kind of structure of the easiest processing, is illustrated embodiments therefore.
