When in latch insertion lockplate, angle of back-rest is non-adjustable；Conversely, when locking latch extracts lockplate, angle of back-rest can be free
Adjustment.The root long handle of generally use one realizes the operation to locking latch in the prior art, however, this will also bring physical dimension
Long, the defects of operating distance is long, space availability ratio is small, inconvenient for operation and manufacturing cost is high, pole is brought to Consumer's Experience
Big influence.
The content of the invention
The present invention is directed to problem above, it is proposed that a kind of delicate structure, small volume, easy to operate, operating distance is short and makes
Cause the lock assembly of this low adjustable chair back.
The technical scheme is that：The chair back is movably connected in the side of seat and its bottom and is fixedly connected with lock
Fixed board, lock hole is offered in the lockplate；The lock assembly includes locking latch, back-moving spring, shifting block, bracing wire, control
Arm, handle and handle box processed；
The locking latch is adapted with lock hole, and the locking latch is located at the side of lock hole and is slidably connected at seat
Bottom, restoring board is fixedly connected with the locking latch, the back-moving spring is socketed the locking latch and is against reset
Between plate and lockplate；Top and the remote locking of locking latch of the bottom of seat and shifting block are hinged in the middle part of the shifting block
The side of plate fits；
The handle box is fixedly connected on the bottom of seat and positioned at shifting block backwards to the side of locking latch, the control arm
The side that bottom is hinged in the handle box and middle part of control arm is passed to outside handle box, and the top of the control arm opens up
Have a storage tank, be provided with fastening spring and fastening steel ball in the storage tank, the fastening spring be fixedly connected on fastening steel ball and
Between the bottom land of storage tank so that fastening steel ball is fitted on the inwall of handle box；The handle is fixedly connected on control arm and worn
Go out on the side to outside handle box, one end of the bracing wire is fixedly connected on the bottom of shifting block and the other end is penetrated in handle box
It is fixedly linked with the top of control arm.
Ball-and-socket is offered on the inwall of the handle box, the ball-and-socket is adapted with fastening steel ball, when handle is away from locking
When plate is rocked to extreme position, a quarter of the fastening steel ball is absorbed in the ball-and-socket.
A pair of limited posts are fixedly connected with the handle box, the control arm is between two limited posts.
Fixed magnet is fixedly connected with one in two limited posts away from lockplate, the control arm is backwards to lockplate
Side be fixedly connected with moving magnet.
The present invention is in use, user back and forth stirs handle, you can so that the chair back is between lock-out state and released state
Enter accommodating switching, meanwhile, the overall structural volume of lock assembly is smaller in this case, movement range is also smaller, therefore, from entirety
It is upper with delicate structure, small volume, it is easy to operate, operating distance is short and manufacturing cost is low the advantages of.
Brief description of the drawings
Fig. 1 is the structural representation of this case,
Fig. 2 be Fig. 1 A-A to sectional view,
Fig. 3 is the structural representation of handle box in this case；
1 is locked out plate in figure, and 2 be locking latch, and 3 be back-moving spring, and 4 be shifting block, and 5 be bracing wire, and 6 be control arm, and 61 be fastening
Spring, 62 be fastening steel ball, and 7 be handle, and 8 be handle box, and 80 be limited post.
Embodiment
As Figure 1-3, the chair back is movably connected in the side of seat and its bottom and is fixedly connected with locking the present invention
Plate 1, lock hole is offered in the lockplate；The lock assembly include locking latch 2, back-moving spring 3, shifting block 4, bracing wire 5,
Control arm 6, handle 7 and handle box 8；
The locking latch 2 is adapted with lock hole, and the locking latch 2 is located at the side of lock hole and is slidably connected at chair
The bottom in face, restoring board is fixedly connected with the locking latch 2, the back-moving spring 3 is socketed the locking latch 2 and supported
Between restoring board and lockplate 1；The middle part of the shifting block 4 is hinged on top and the locking latch of the bottom of seat and shifting block 4
2 sides away from lockplate 1 fit；
The handle box 8 is fixedly connected on the bottom of seat and positioned at shifting block 4 backwards to the side of locking latch 2, the control arm
The side that 6 bottom is hinged in the handle box 8 and middle part of control arm 6 is passed to outside handle box 8, the control arm 6 it is upper
Portion offers storage tank, and fastening spring 61 and fastening steel ball 62 are provided with the storage tank, and the fastening spring 61 is fixedly connected
Between fastening steel ball 62 and the bottom land of storage tank so that fastening steel ball 62 is fitted on the inwall of handle box 8；The handle 7
It is fixedly connected on control arm 6 to pass to the side outside handle box 8, one end of the bracing wire 5 is fixedly connected under shifting block 4
The top that portion and the other end penetrate in handle box 8 with control arm 6 is fixedly linked.So, when control arm under the drive of handle it is remote
When being swung from lockplate, the bottom of shifting block can be pulled to be swung away from lockplate by bracing wire, so as to be promoted by the top of shifting block
In locking latch insertion lock hole, the locking of the chair back is realized；And when handle drives and controls and swung towards lockplate, in bracing wire
Will be without pulling force, so that locking latch exits lock hole in the presence of back-moving spring so that the chair back can be adjusted freely.Its
In, due to the presence of fastening steel ball and fastening spring, it will make it that handle and control arm, can be with handle boxes when user does not operate
Geo-stationary is kept, so as to the stable lockup state for maintaining the chair back, ensure that the reliability of lock assembly.
In summary, the present invention is in use, user back and forth stirs handle, you can so that the chair back is in lock-out state and unblock
Enter accommodating switching between state, meanwhile, the overall structural volume of lock assembly is smaller in this case, movement range is also smaller, because
This, on the whole with delicate structure, small volume, it is easy to operate, operating distance is short and manufacturing cost is low the advantages of.
Ball-and-socket is offered on the inwall of the handle box, the ball-and-socket is adapted with fastening steel ball, when handle is away from locking
When plate is rocked to extreme position, a quarter of the fastening steel ball is absorbed in the ball-and-socket.So, when handle enters away from lockplate
Row swings and when being rocked to extreme position, the position of stationary balls that can be more preferable, more stable by ball-and-socket and control arm；Exist
When make it that the chair back is fixed in dead bolt insertion lockplate, the lockup state for maintaining the chair back that can be more stable is effectively ensured
The reliability of lock assembly.
A pair of limited posts 80 are fixedly connected with the handle box 8, the control arm is between two limited posts.So as to right
The limit swing position of control arm is defined.
Fixed magnet is fixedly connected with one in two limited posts away from lockplate, the control arm is backwards to lockplate
Side be fixedly connected with moving magnet.So, when handle is swung away from lockplate and is rocked to extreme position, can pass through
The position for the fixation control arm that the cooperation of fixed magnet and moving magnet can further stablize；So as to be inserted in dead bolt in lockplate
During so that the chair back being fixed, the lockup state for maintaining the chair back that can further stablize, and then locking group has further been effectively ensured
The reliability of part.
