Abstract
The composite polyurethane-spring buffer consists of mainly bottom flange, large sleeve with inner buckle, small sleeve with outer buckle, and top flange. It features the tight connection between the bottom flange and the large sleeve, the clip connection between the large sleeve and the small sleeve, the tight connection between the small sleeve and the top flange, and the polyurethane sleeve with inside spring set between the large sleeve and the small sleeve and contacting the bottom flange and the top flange. Compared with available technology, the present invention has the advantages of simple structure, low cost, high buffering effect and high durability.
Description
Technical field
The present invention relates to a kind of polyurethane and spring combined type buffer, relate to a kind of buffer that is combined with each other and makes by polyurethane and spring specifically.
Technical background
At present, buffer has become large-scale sports equipment necessary part, it is several that the buffer that is applied to main equipment mainly is divided into rubber type, metal spring type, hydraulic type, liquid-gas type and damped type, but all there is different shortcomings in above-mentioned various buffer, and the rubber type buffer is soon aging and cushion effect is less; Metal spring type draft gear recoil power is big and noise is also big, and cushioning effect is poor, also easy corrosion under the environment of humidity; And hydraulic type and liquid-gas type buffer all exist easy-to-leak liquid, gas leak phenomenon, repair in case the leakage cushioning effect sharply descends and is not easy, so require machining accuracy very high, corresponding manufacture cost also is multiplied; The damped type buffer more can not be widely used owing to the cost height.In sum, be badly in need of on the market that a kind of anti-aging, good buffer effect, manufacturing are simple, the buffer of low cost of manufacture.
Summary of the invention
The object of the present invention is to provide a kind of polyurethane and spring combined type buffer, it processes simple, anti-aging, good buffer effect, with low cost, and overcomes the deficiencies in the prior art.
The object of the present invention is achieved like this: it mainly by flange chassis (1), the big sleeve of internal fastening type (2), exterior buckle type small sleeve (3), take over a business (4) and form, it is characterized in that: flange chassis (1) top edge is provided with ring (12), and the center is provided with center chassis ring (11) and is fastenedly connected with the big sleeve of internal fastening type (2); The mutual snapping of one end of big sleeve of internal fastening type (2) and exterior buckle type small sleeve (3), and the big sleeve of internal fastening type (2) is provided with ring (13); The other end of exterior buckle type small sleeve (3) with take over a business (4) and be fastenedly connected, and the top edge of taking over a business (4) is provided with ring (14), the center is provided with center ring (21); The big sleeve of internal fastening type (2) is provided with polyurethane rings tube (5), spring (6) with exterior buckle type small sleeve (3) inside, spring (6) casts in polyurethane rings tube (5) inside, and polyurethane rings tube (5) and spring (6) two ends are respectively with flange chassis (1) with take over a business (4) and contact; Flange chassis (1), the big sleeve of internal fastening type (2), exterior buckle type small sleeve (3), take over a business (4), the axis coinciding of polyurethane rings tube (5), spring (6); Ring (12), (13) connect by bridle line (51), and ring (13), (14) connect by bridle line (52), center chassis ring (11) with take over a business center ring (21) and be connected by bridle line (53).
The present invention compared with prior art, it is simple in structure, with low cost, cushioning effect is better, durable in use.
Description of drawings
Fig. 1 is a structural principle generalized section of the present invention.
Wherein: 1, flange chassis, 2, the big sleeve of internal fastening type, 3, the exterior buckle type small sleeve, 4, take over a business, 5, polyurethane rings tube, 6 springs, 11, the center chassis ring, 21, take over a business center ring, 12,13,14, ring, 51,52,53, bridle line
Embodiment
Further specify the present invention below in conjunction with drawings and Examples:
Referring to accompanying drawing, the present invention mainly by flange chassis 1, the big sleeve 2 of internal fastening type, exterior buckle type small sleeve 3, take over a business 4 and form, wherein, flange chassis 1 top edge is welded with ring 12, the center be welded with center chassis ring 11 and with big sleeve 2 welding of internal fastening type; The mutual snapping of one end of big sleeve 2 of internal fastening type and exterior buckle type small sleeve 3, and be welded with ring 13 on the big sleeve 2 of internal fastening type; The other end of exterior buckle type small sleeve 3 with take over a business 4 welding, and take over a business 4 top edge and be welded with ring 14, the center is welded with center ring 21; The big sleeve of internal fastening type 2 is provided with polyurethane rings tube 5 and spring 6 with exterior buckle type small sleeve 3 inside, and spring 6 casts in polyurethane rings tube 5 inside, and polyurethane rings tube 5 and spring 6 two ends respectively with flange chassis 1 with take over a business 4 and contact; Flange chassis 1, the big sleeve 2 of internal fastening type, exterior buckle type small sleeve 3, take over a business 4, the axis coinciding of polyurethane rings tube 5, spring 6; Ring 12,13 connects by wire rope 51, and ring 13,14 connects by wire rope 52, and center chassis ring 11 is taken over a business center ring 2 and connected by wire rope 53.Connecting each several parts with wire rope 51,52,53 is directly to fall when preventing that this part from coming off, and uses safer.Because spring 6 casts in polyurethane rings tube 5 inside, thereby spring 6 contact with the outside and be difficult for agingly, add the elasticity that polyurethane rings tube 5 is own to make this buffer buffers better effects if that it is more lasting to use.
