Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of folding seat of the utility model.
In accompanying drawing, the 1. chair back; 2. seat support; 3. fore-stock; 4. after-poppet; 5. connecting rod; 6. the second installing plate; 61. is protruding; 7. push rod; 8. fastener; 9. the first installing plate.
Detailed description of the invention
A kind of folding seat, comprise the chair back 1, seat support 2, fore-stock 3 and after-poppet 4, described fore-stock 3 and after-poppet 4 support are handed over and are hingedly connected with connecting rod 5, the described chair back 1 is fixedly mounted on the side, upper top of fore-stock 1, described seat support 2 is articulated and connected on fore-stock 3 and described seat support 2 and after-poppet 4 are articulated and connected, described seat support 2 can rotate around the position be articulated and connected with fore-stock 3, when seat support 2 turn to horizontal level parallel to the ground time, between fore-stock 3 and after-poppet 4, motion is inverted " y " shape structure mutually, fore-stock 3 and after-poppet 4 supported folding chair, folding seat is in deployed condition, when rotate seat support 2 rotate backward make it not parallel to the ground time, fore-stock 3 and after-poppet 4 mutually motion are close to fore-stock 3, after-poppet 4, the state of seat support 2 in convergence level, now folding seat folds.
Described fore-stock 3 and after-poppet 4 Bracket setting have the locking device for limiting fore-stock 3 and after-poppet 4 activity, described locking device comprises the first installing plate 9 and the second installing plate 6, described first installing plate 9 is fixedly connected with after-poppet 4 screw respectively at fore-stock 3 with the second installing plate 6, and the first installing plate 9 and the second installing plate 6 are separately positioned on fore-stock 3 two sides relative with after-poppet 4, described second installing plate 6 has been wholely set protruding 61 towards fore-stock 3 side, described first installing plate 9 is hingedly connected with push rod 7 towards after-poppet 4 side, described push rod 7 can rotate around the first installing plate 9, when push rod 7 turns to horizontal level towards after-poppet 4, push rod 7 just in time rides on protruding 61 and withstands the second installing plate 6, now, people is sitting on seat support 2, even if center of gravity is to the rear, when seat support 2 has the trend of turning over backward, push rod 7 second installing plate 6 that can withstand on after-poppet 4 makes fore-stock 3 and after-poppet 4 can not be close, ensure that folding seat in use can not fold, security performance is high, meanwhile, this is relatively simple for structure, and the mode that locking device adopts screw to be connected with fore-stock 3 and after-poppet 4 is fixedly connected with, and makes locking device be easy to dismounting, facilitates it to change, thus improve the service time of folding seat further.
Further, described push rod 7 is set to two and has been wholely set fastener 8 between two push rods 7, such setting, ensure that push rod 7 has enough intensity when withstanding the second installing plate 6, when turning over after avoiding seat support 2 center of gravity to the rear, after power of turning over higher than the intensity of push rod 7, push rod 7 is damaged, unfailing performance is high; Simultaneously, push rod 7 is wholely set fastener 8, can ensure that two push rods 7 can be synchronized with the movement, when control push rod 7 rotates, only need to control one of them push rod 7 and move, do not need to control two push rods 7 respectively, structure is simple, easy to operate, support strength is high, ensure that folding seat anti-after to turn over performance good.
Described locking device adopts high-strength engineering plastic to make, high-strength engineering plastic is adopted to make locking device, quality is light, cost is low and intensity good, improve the practicality of folding seat, PEEK engineering plastics are preferably used at this, PEEK engineering plastics resistance to elevated temperatures is good, mechanical performance is excellent, high and the resistance to chemical attack of intensity, fire-retardant, peel resistance, anti-wear performance is good, use PEEK engineering plastics, effectively can improve the service time of locking device, thus improve the service life of folding seat, its lower cost ensure that the cost of folding seat is low, to be easy to accept by client.
In addition, described locking device setting position and the distance of fore-stock 3 in the chair back 1 opposite end are 150 ~ 250mm.Preferred 200mm, ensure that locking device can be installed in place, ensure its stressed good, effect of applying large, and easy to operate to it of people, only need lift gently with pin or put down, reliably easy, simple and practical.
Concrete occupation mode of the present utility model is as follows: when folding seat needs to use, stirring seat support 2 front end makes seat support 2 rotate around its articulated section, now, fore-stock 3 and after-poppet 4 are separated into inverted " y " shape, seat support 2 level, push rod 7 in locking device prevents from level riding on protruding 61 and withstands the second installing plate 6, and the fore-stock 3 being and after-poppet 4 can not close to each otherly fold, and improve the security performance of folding seat; When folding seat needs folding, lifted by push rod 7 with pin, push rod 7 can not withstand the second installing plate 6 again, now, upwards move the front end of seat support 2, fore-stock 3 and after-poppet 4 close to each other, folding seat folds, and the utility model structure is simple, easy to operate, security performance is high, practicality is good.
