The control device includes the cam 4 being rotatably arranged on rotation seat 2, and the driving group that control cam 4 rotates Part, when backrest 7 and bed body 6 are during the opposite expansion of folded state, driving assembly drives cam 4 to rotate, and cam 4 drives pawl 3 separate with ratchet portion 21, until pawl 3 and ratchet portion 21 cooperate, 4 structural elements of cam when backrest 7 and bed body 6 are fully deployed It is less, structure is simple, facilitate design produce, advantageously reduce production cost.

It is preferred that being provided with the elastic component 5 of driving pawl 3 and the cooperation of ratchet portion 21 in the mounting base 1, elastic component 5 drives spine Pawl 3 is pushed against always on cam 4, and being provided with for elastic component 5 cooperates conducive to pawl 3 and ratchet portion 21, avoids spine in use process Pawl 3 is undesirably fallen off with ratchet portion 21, influences the normal use of user, and elastic component 5 is spring leaf, spring leaf two in cup embodiment Side is pushed against respectively on pawl 3 and mounting base 1.

Limiting slot 41 is provided on the cam 4, the driving component is the retention bead 22 being arranged on rotation seat 2, Retention bead 22 and limiting slot 41 cooperate, and in backrest 7 and 6 relative rotational motion of bed body, retention bead 22 drives cam 4 and peace Seat 1 is filled to relatively rotate, thus control pawl 3 and the cooperation in ratchet portion 21 or separate, retention bead 22 and rotation seat 2 in the structure It moving synchronously, and when the relative motion in limiting slot 41 of retention bead 22, retention bead 22 cannot drive cam 4 to move, from And realize that backrest 7 and bed body 6 are smoothly unfolded, and avoid backrest 7 and 6 unintentional rotation of bed body in use process.

The preferably described rotation seat 2 of the utility model is made of the metal of integral type, and two groups of ratchet portions are provided on rotation seat 2 21, two groups of claws 31 cooperated with ratchet portion 21 are provided on pawl 3, cam 4 is arranged between two groups of ratchet portions 21, and two groups Retention bead 22 is provided in ratchet portion 21, two groups of distributions of retention bead 22 are penetrated in limiting slot 41 from 4 two sides of cam, installed Retention bead 22 is installed in limiting slot 41 by the elasticity of Shi Liyong metal, the structure avoid in use process retention bead 22 with Limiting slot 41 is undesirably fallen off, and improves the stability of physical examination result.

It is provided on the cam 4 for controlling the abutting portion 44 isolated with ratchet portion 21 of pawl 3, and for controlling spine The concave part 42 that pawl 3 and ratchet portion 21 cooperate, and space protrusion 43 is provided between abutting portion 44 and concave part 42, which keeps away During having exempted from backrest 7 and the expansion of bed body 6, abutting portion 44 and concave part 42 cooperate, so that it is opposite with bed body 6 to influence backrest 7 Expansion, influences adjusting of the user to backrest 7.

The pawl 3 is rotatably arranged in mounting base 1, and the clamping protrusion 32 cooperated with cam 4, bullet are provided on pawl 3 Property the driving clamping protrusion of part 5 32 be pushed against on cam 4, when folded against again after backrest 7 and bed body 6 are fully deployed, be clamped convex It plays 32 to be pushed against in concave part 42, until clamping protrusion 32 takes off from concave part 42 after retention bead 22 drives cam 4 to rotate From the structure is conducive to the cooperation of pawl 3 Yu cam 4,4 unintentional rotation of cam in use process is avoided, to influence user Normal use.

Specifically used mode

1, when backrest 7 and bed body 6 are folded against, the clamping protrusion 32 on pawl 3 is pushed against the abutting portion 44 of cam 4 On, and separate pawl 3 with the ratchet portion 21 on rotation seat 2, rotation seat 2 is freely rotated with mounting base 1.

2, when backrest 7 and bed body 6 are unfolded from folded state, the first free movement in limiting slot 41 of retention bead 22, directly It is pushed against to retention bead 22 on the side wall of limiting slot 41, then retention bead 22 pushes against the side wall of limiting slot 41 and drives cam 4 rotations, until backrest 7 is fully deployed with bed body 6, clamping protrusion 32 enters in concave part 42 at this time, and claw 31 and ratchet portion 21 cooperate.

3, enter in concave part 42 when backrest 7 and bed body 6 are adjusted from unfolded state in use, being clamped protrusion 32, and Claw 31 and ratchet portion 21 cooperate, and at this time since claw 31 and ratchet portion 21 cooperate, backrest 7 can be folded freely, without It is able to carry out opposite expansion, user is in use, backrest 7 will not surprisingly be unfolded.

4, when backrest 7 is badly in need of folding, retention bead 22 drives cam 4 to rotate, and takes off clamping protrusion 32 from concave part 42 From, and separating pawl 3 with ratchet portion 21, backrest 7 can be freely rotated with bed body 6.

Above-described embodiment is only the preferred embodiment of the utility model, not limits the protection model of the utility model according to this It encloses, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by the protection of the utility model Within the scope of.
