Abstract
The utility model relates to a safety protection device for a folding chair, which comprises a chair back frame. A chair seat is hinged with the chair back frame; a support frame is arranged below a hinged point of the chair seat which is positioned on the chair back frame; a longitudinal rib is fixedly arranged at the lower surface of the chair seat; both ends of the longitudinal rib are fixedly arranged at the lower surface of the chair seat; gaps are arranged between the middle part of the longitudinal rib and the lower surface of the chair seat; an upper beam of the support frame crosses the gaps. The utility model is characterized in that a clamping hook is hinged with the front end of the lower surface of the chair seat; a torsional spring is arranged between the clamping hook and the hinged point; when a folding chair is unfold and the support frame is positioned at a front spacing point, the hook parts of the clamping hook can penetrate a communicating groove arranged on the longitudinal rib and is clamped at the upper beam of the support frame. The goals of the utility model are that when the users sit on chairs, the uncontrollable retracting actions of the folding chairs are generated because the gravity center is close to back, the structures of the folding chairs are kept stably, the users are protected, and especially, the safety of children are ensured.
Description
Technical field
The utility model relates to a kind of improvement of folding seat, relates in particular to a kind of protective device of strengthening folding seat safety.
Background technology
Existing a kind of folding seat as shown in Figure 1, comprise on seat back frame 1, the seat back frame 1 and be hinged with seat 2, the below that is positioned at seat pin joint 21 on the seat back frame 1 also is hinged with support frame 3, seat 2 lower surfaces are installed with longitudinal rib 4, longitudinal rib 4 two ends are fixedly arranged on seat 2 lower surfaces, have space 41 between longitudinal rib 4 middle parts and seat 2 lower surfaces, support frame upper beam 31 crosses described space 41.Seat 2 and support frame 3 can rotate around pin joint separately during use, longitudinal rib 4 not only plays the reinforcing supporting role, and the space 41 between itself and seat 2 lower surfaces can be for crossing 31 motions of putting the beams in place of wherein support frame, the space front end plays the put the beams in place effect in 31 prosodetic sites 43 of support frame, the effect of the spacing point in support frame underbeam 31 backs is played in the rear end, space, the range of movement of restriction support frame upper beam 31.The shortcoming of the prior art is, if user, especially children sit thereon, whole centers of gravity may be placed the seat part 22 after seat 2 and seat back frame 1 pin joint 21, seat 2 stressed meetings are upwards rotated around pin joint 21, this moment support frame 31 infinite places backward of putting the beams in place, also can move backward, also both folding seat is equivalent to pack up the action of folding seat, and structure plays pendulum, and the people who also is sitting on the folding seat is produced dangerous consequences.
Summary of the invention
The utility model provides a kind of safety guard of folding seat; its purpose is to overcome above-mentioned the deficiencies in the prior art part; when making the user be sitting on the chair; can folding seat is uncontrollable pack up action owing to center of gravity takes place after depending on very much; keep folding chair structure stable; protection user, especially children's safety.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of safety guard of folding seat; comprise seat back frame; be hinged with seat on the seat back frame; the below that is positioned at the seat pin joint on the seat back frame also is hinged with support frame; the seat lower surface is installed with longitudinal rib; the longitudinal rib two ends are fixedly arranged on the seat lower surface; has the space between longitudinal rib middle part and the seat lower surface; support frame is put the beams in place and is crossed described space; it is characterized in that: the front end of seat lower surface is hinged with a grab; also be provided with torsion spring between grab and the pin joint; when folding seat is launched; when bracing frame was positioned at the prosodetic site, the hook portion of grab just can be passed the groove that is provided with on the longitudinal rib and the blocking support frame is put the beams in place.
Beam section is circular on the support frame, and the inner curve of grab hook portion is an arc, and its inner curve was put the beams in place with support frame and cooperated when grab hook portion blocking support frame was put the beams in place.
Grab press section external position also has baffle plate and is fixedly arranged on the seat lower surface, and height of baffle plate is no more than the grab press section.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
The utility model most preferred embodiment as shown in Figure 2; a kind of safety guard of folding seat; comprise seat back frame 1; be hinged with seat 2 on the seat back frame 1; the below that is positioned at seat pin joint 21 on the seat back frame 1 also is hinged with support frame 3; seat 2 lower surfaces are installed with longitudinal rib 4; longitudinal rib 4 two ends are fixedly arranged on seat 2 lower surfaces; has space 41 between longitudinal rib 4 middle parts and seat 2 lower surfaces; support frame upper beam 31 crosses described space 41; the front end of seat 2 lower surfaces is hinged with a grab 5; grab 5 has hook portion 51 and press section 52; also be provided with torsion spring 6 between grab 5 and the pin joint 53; when folding seat is launched; bracing frame puts the beams in place 31 when being positioned at prosodetic site 43, and the hook portion 51 of grab 5 just can be passed the groove 42 that is provided with on the longitudinal rib 4 and the blocking support frame puts the beams in place 31.
Support frame is put the beams in place 31 cross sections for circular, and the inner curve 511 of grab 5 hook portions 51 be an arc, and grab 5 hook portions 51 blocking support frames 31 o'clock its inner curves 511 of putting the beams in place cooperate with support frame upper beam 31.
Grab 5 press sections 52 external positions also have baffle plate 7 and are fixedly arranged on seat 2 lower surfaces, and baffle plate 7 highly is no more than grab 5 press sections 52.
The user with folding seat when folded state expands into user mode fully, the user pushes the press section 52 of grab 5, support frame is put the beams in place 31 to be reached and is limited in prosodetic site 43, this moment, the user decontroled the press section 52 of grab 5, the blocking support frame puts the beams in place 31 because the active force of jump ring 6 rebounds and the hook portion 51 of grab 5 just can be passed the groove 42 that is provided with on the longitudinal rib 4 for grab 5, and its inner curve 511 and support frame are put the beams in place and 31 cooperated with restriction upper beam 31 better and move.If the user places seat 2 and seat back frame 1 pin joint 21 seat part 22 afterwards with whole centers of gravity, the seat 2 stressed trend of upwards rotating that have around pin joint 21, because this moment, support frame upper beam 31 was spacing by grab 5 hook portions 51, can't move backward, seat 2 also can't rotate around pin joint 21 naturally, and folding chair structure is stable.Desire to pack up folding seat, the user only need push grab 5 press sections 52, and support frame upper beam 31 can be moved backward, gets final product.
Baffle plate 7 effect that grab 5 external positions are fixedly arranged on seat 2 lower surfaces be prevent the user especially children will point the space 8 between insertion grab 5 press sections 51 and seat 2 lower surfaces because of carelessness and may be clipped to injured situation, further increase the security of folding seat.
