Abstract
The invention discloses a multi-angle self-locking positioning hinge mechanism which comprises a cap (1), a spring (2), a rotating shaft (3), a limiting rod (4) and a shaft sleeve (5). The spring (2), the limiting rod (4), the shaft sleeve (5) and the rotating shaft (3) are mounted coaxially. A limiting block at one end of the limiting rod (4) is clamped in a limiting groove of the shaft sleeve (5), and the other end of the limiting rod (4) is in threaded connection with the cap (1). When a door is opened or closed, the cap (1) is pressed down, the spring (2) is compressed, and the limiting rod (4) is disengaged out of the limiting groove of the shaft sleeve (5); the limiting block slides on the end face of the shaft sleeve (5), and the limiting rod (4) together with the rotating shaft (3) rotates under the constraint of a limiting groove of the rotating shaft (3); when the limiting rod (4) rotates to a 90-degree position or a 180-degree position, under the action of return force of the spring (2), the limiting block is simultaneously clamped in the limiting groove of the rotating shaft (3) and the limiting groove of the shaft sleeve (5), the rotating shaft (3) and the shaft sleeve (5) cannot rotate relatively, and self-locking positioning is achieved. Through the multi-angle self-locking positioning hinge mechanism, the problem that self-locking positioning of a conventional hinge cannot be achieved is solved.
Description
Technical field
The present invention relates to a kind of linkage, particularly a kind of multi-angle lock-bit linkage.
Background technology
Linkage, as a kind of transmission mechanism, is used to connection two objects and allows to make mechanical device in relative rotation between the two.With in the mechanical connecting structure of rotation formula folding, apply very extensive in the installation of particularly various door, window.Conventional hinge mechanism comprises: rotating shaft and axle sleeve, and rotating shaft is placed in axle sleeve, and rotating shaft can rotate freely in axle sleeve, but can not lock-bit.
Summary of the invention
The object of the invention is to provide a kind of multi-angle lock-bit linkage, and solving conventional hinge mechanism can not the problem of lock-bit.
A kind of multi-angle lock-bit linkage, comprising: rotating shaft, axle sleeve, also comprise: block, spring and gag lever post.
Axle sleeve is the circle cover of a side end face with two stopper slots, and stopper slot is radially slotted, each other in 90 ° of distributions; Rotating shaft is the different stepped cylinder of two ends diameter, and the large one end end face of diameter is with counterbore, and hole is opened vertically from end face in one end that diameter is little, and end radially has stopper slot; Gag lever post is L shape, and long limit is cylinder and end belt external screw thread, and minor face is limited block, limited block shape and stopper slot form fit; Block is cylinder, an end band internal thread.Rotating shaft is placed in axle sleeve, and the stopper slot in rotating shaft aligns with the stopper slot of first on axle sleeve, and gag lever post inserts rotating shaft from axle sleeve side and is stuck in rotating shaft stopper slot, and spring axis of rotation counterbore end is coaxially inserted in gag lever post, and block is connected with gag lever post end thread.
Described linkage is fixedly connected with door, and when door is in closed condition, the rectangle limited block on gag lever post fits in end face of shaft bush infinite place slot and puts, and gag lever post drives block to make spring be in compressed state.In door opening procedure, gag lever post rotates together in company with it under the constraint of rotating shaft stopper slot in axle sleeve, when going to 90 ° of positions, there is first stopper slot in end face of shaft bush, under the effect of recoil of spring power, gag lever post moves upward, limited block snaps in end face of shaft bush first stopper slot, because gag lever post snaps in the stopper slot of rotating shaft and axle sleeve simultaneously, forms latch structure, the two cannot be relatively rotated, and door is opening 90 ° of position lock-bits.If continued to open to greater angle by door, need by lower cover cap, spring is compressed, and gag lever post moves downward until deviate from axle sleeve stopper slot under the drive of block.Now, gag lever post can rotate together in company with it under the constraint of rotating shaft stopper slot in axle sleeve, until during 180 ° of positions, again there is stopper slot in end face of shaft bush, under the effect of recoil of spring power, limited block on gag lever post snaps in end face of shaft bush stopper slot again, and door is opening 180 ° of position lock-bits.At closing time, by lower cover cap, spring is compressed, and gag lever post moves downward until deviate from axle sleeve stopper slot under the drive of block, now, rotating shaft can be made to rotate in axle sleeve until position of closing the door.
Linkage of the present invention utilizes compression and the resilience of spring, block, forms latch structure, realizes the lock-bit in multiple angle, do not need the supplemental support of other devices by gag lever post and stopper slot, and structure is simple, easy for installation.

Detailed description of the invention
A kind of multi-angle lock-bit linkage, comprising: rotating shaft 3 and axle sleeve 5, also comprise: block 1, spring 2 and gag lever post 4.
Axle sleeve 5 is the circle cover of a side end face with two stopper slots, and stopper slot is radially slotted, each other in 90 ° of distributions; Rotating shaft 3 is the different stepped cylinder of two ends diameter, and the large one end end face of diameter is with counterbore, and hole is opened vertically from end face in one end that diameter is little, and end radially has stopper slot; Gag lever post 4 is L shape, and long limit is cylinder and end belt external screw thread, and minor face is limited block, limited block shape and stopper slot form fit; Block 1 is cylinder, an end band internal thread.Rotating shaft 5 is placed in axle sleeve 3, stopper slot in rotating shaft 5 aligns with the stopper slot of first on axle sleeve 3, gag lever post 4 inserts rotating shaft 3 from axle sleeve 5 side and is stuck in rotating shaft stopper slot, and spring 2 axis of rotation 3 counterbore end is coaxially inserted in gag lever post 4, and block 1 is connected with gag lever post 4 end thread.
Described linkage is fixedly connected with door, and when door is in closed condition, the rectangle limited block on gag lever post 4 fits in axle sleeve 5 end face infinite place slot and puts, and gag lever post 4 drives block 1 to make spring 2 be in compressed state.In door opening procedure, gag lever post 4 rotates together in company with it under the constraint of rotating shaft 3 stopper slot in axle sleeve 5, when going to 90 ° of positions, there is first stopper slot in axle sleeve 5 end face, under the effect of spring 2 screen resilience, gag lever post 4 moves upward, limited block snaps in axle sleeve 5 end face first stopper slot, because gag lever post 4 snaps in the stopper slot of rotating shaft 3 and axle sleeve 5 simultaneously, forms latch structure, the two cannot be relatively rotated, and door is opening 90 ° of position lock-bits.If continued to open to greater angle by door, need by lower cover cap 1, spring 2 is compressed, and gag lever post 4 moves downward until deviate from axle sleeve 5 stopper slot under the drive of block 1.Now, gag lever post 4 can rotate together in company with it under the constraint of rotating shaft 3 stopper slot in axle sleeve 5, until during 180 ° of positions, again there is stopper slot in axle sleeve 5 end face, under the effect of spring 2 screen resilience, limited block on gag lever post 4 snaps in axle sleeve 5 end face stopper slot again, and door is opening 180 ° of position lock-bits.At closing time, by lower cover cap 1, spring 2 is compressed, and gag lever post 4 moves downward until deviate from axle sleeve 5 stopper slot under the drive of block 1, now, rotating shaft 3 can be made to rotate until position of closing the door in axle sleeve 5.
