Abstract

The utility model discloses a pin type tee socket joint device, which relates to fittings of a rebounder, and comprises a first round surface tube, a second round surface tube and a vertical tube, andalso comprises a tee transverse tube, wherein the vertical tube is welded on the outer wall of the tee transverse tube, and a flat pin is welded in the tee transverse tube; a first flat groove is arranged at the end of the first round surface tube, and a second flat groove is arranged at the end of the second round surface tube; one end of the first round surface tube is arranged at one end of the tee transverse tube in an inserting way, and the other end of the tee transverse tube is arranged at one end of the second round surface tube in an inserting way; and the two ends of the flat pin are respectively clamped in the first flat groove and the second flat groove. When being assembled, the two round surface tubes are inserted in the tee transverse tube, and the flat grooves of the two round surface tubes can closely clamp the flat pin in the tee transverse tube, so that the supporting leg tube of the rebounder can not sway horizontally, the service life of the rebounder is prolonged, and the safety of the rebounder is improved; and in addition, the packing volume is small, the assembly is convenient, and the stability and practicality are reliable.

Description

Pin type threeway sleeve joint device

Technical field

The utility model relates to the accessory of trampoline, relates in particular to the bedstead of trampoline and the connection set between the leg pipe.

Background technique

At present, existing trampoline comprises bedstead and the leg pipe around bed surface, the bed surface, bedstead is welded by disc pipe and disc pipe, there is following shortcoming in this welding manner: 1, expose to the weather owing to weld, using in the very short time and will get rusty and corrode, thus the Security and the service time of minimizing trampoline.2, the workpiece after the welding is big, can't carry out surface treatment, as plating, hot dip, plastic-blasting etc.3, make that the volume of trampoline is big, transportation is inconvenient.

The model utility content

The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of pin type threeway sleeve joint device to be provided, make safe, the workpiece I of trampoline carry out surface treatment and volume little.

The purpose of this utility model is achieved in that pin type threeway sleeve joint device, comprise the first disc pipe, second disc pipe and the vertical tube, also comprise the threeway transverse tube, described vertical tube is vertically welded in the outer wall of threeway transverse tube, the flat type pin of welding in the threeway transverse tube, the end of the described first disc pipe is provided with the first flat type groove, the end of the second disc pipe is provided with the second flat type groove, one end of the first disc pipe is plugged on an end of threeway transverse tube, a plant end of the second disc pipe of the other end of threeway transverse tube, the two ends of flat type pin are stuck in the first flat type groove and the second flat type groove.

The beneficial effects of the utility model are: during assembling, two disc pipes are inserted in the threeway transverse tube, the flat type groove of two disc pipes can tightly block the flat type pin in the threeway transverse tube, such assembling mode makes the leg Guan Buhui of trampoline swing, the working life and the Security of trampoline have been increased, box volume is little in addition, and ease of assembly has reliable stability and practicability.
