2, use two groups of first connecting rods that are parallel to each other, second connecting rod and third connecting rod linkage structures below seat board, connect and support seat board, fore-stock and after-poppet effect thereby better play, bearing capacity is strengthened greatly, is beneficial to long-time use.
3, be provided with the front rod of many levels between two fore-stocks, be provided with many horizontal rear connecting rods between two after-poppets, two fore-stocks are connected more firm with two after-poppets, use also safer.
[description of drawings]
Be described in further detail below in conjunction with accompanying drawing and embodiment of the present utility model:
Fig. 1 is the utility model deployed condition stereogram;
Fig. 2 is the stereogram in the utility model folding process;
Front view when Fig. 3 launches for the utility model.
[specific embodiment]
The folding seat that the utility model is related, it includes seat board 1, fore-stock 2 and after-poppet 3, described seat board 1 front end bilateral symmetry is provided with arc groove 11, two fore-stocks 2 upper ends and lays respectively in above-mentioned two arc grooves 11, and fore-stock 2 is hinged by bearing pin 8 and seat board 1.Be provided with first connecting rod 4, second connecting rod 5 and third connecting rod 6 below the described seat board 1; Described first connecting rod 4 upper ends are hinged on above-mentioned seat board 1 downside, and its lower end and described after-poppet 3 middle parts are hinged; Described second connecting rod 5 lower ends are hinged on the described fore-stock 2, and its upper end is hinged on the above-mentioned first connecting rod 4; Described third connecting rod 6 lower ends are hinged on above-mentioned after-poppet 3 bottoms, and its upper end is hinged on the above-mentioned second connecting rod 5.
When folding, the user is on the other hand by on after-poppet 3, thereby another is handed up and rises seat board 1 near after-poppet 3 one ends drive first connecting rod 4, second connecting rod 5 and third connecting rod 6 interlocks, its concrete folding process is as follows: first connecting rod 4 is along with seat board 1 makes progress together, rotate and draw close to after-poppet 3 around the hinged place of its lower end, second connecting rod 5 upper ends are along with first connecting rod 4 is done rotation of drawing close to after-poppet 3 and parallel the moving of drawing close to after-poppet 3 by its lower end drive fore-stock 2 works together; Third connecting rod 6 upper ends are along with second connecting rod 5 makes progress together, rotate and draw close around the hinged place of its lower end to after-poppet 3, first connecting rod 4 is transferred to vertically by original level after folding the finishing, and second connecting rod 5 and third connecting rod 6 also transfer to vertically for original heeling condition.Otherwise, then the utility model that is folding can have been launched.
Described seat board 1 downside is fixedly connected with straight plate 7, and described first connecting rod 4 upper ends are hinged on the above-mentioned straight plate 7.
Wherein, seat board 1 downside is provided with recess 12, and described straight plate 7 is positioned at this recess 12, and recess 12 is provided with outward extending bar-shaped trough 120 near after-poppet 3 one sides; After the expansion, described first connecting rod 4 front portions can be inserted in the above-mentioned recess 12, and then be inserted in the recess 12 outward extending bar-shaped troughs 120 at its rear portion.Recess 12, bar-shaped trough 120 groove depths are consistent with above-mentioned arc groove 11 degree of depth, keep level so that launch back seat plate 1.
Deployed condition as shown in Figure 1, in the use, user's weight passes to the fore-stock 2 of after-poppet 3 and seat board 1 front portion by the first connecting rod 4 that is in level, and first connecting rod 4 is easy to be bent downwardly distortion when inferior, needs second connecting rod 5 to support.Because second connecting rod 5 two ends also are movably hinged, it supports unstable to first connecting rod 4, by form the support of dihedral with third connecting rod 6, first connecting rod 4 holding capacity are passed to fore-stock 2 and after-poppet 3, significantly reduced the stressed of hinged places, first connecting rod 4 two ends like this, be beneficial to the utility model and use for a long time.In order to strengthen bearing capacity of the present utility model, as shown in Figure 2, the utility model is provided with two groups of above-mentioned three bar linkage structures that are parallel to each other, thereby better plays the effect that connects seat board 1, fore-stock 2 and after-poppet 3 and support seat board 1.
