Abstract
The utility model relates to a locking device, and in particular relates to a device for adjusting the position of a steel cable and locking the steel cable by controlling a spring to unclamp and clamp the steel cable through a cam handle. According to the solution provided by the utility model, the steel cable penetrates through a circular hole of a shell, and the clamping state of the steel cable is controlled by pressing the cam handle, so that the steel cable can be locked and unlocked to adjust the height of an object. The locking device comprises the shell, a shaft, the spring, the cam handle and the like, wherein the steel cable can be locked and unlocked by changing the state of the steel cable under the control of the spring through the cam handle. According to the adopted scheme, when the locking device is used, the cam handle is pressed down, the spring is in a compression state, the shaft moves leftwards, and the steel cable is in a free state, so that the locking device can move to adjust the height; the cam handle is unlocked, the shaft moves rightwards under the action of the elastic force of the spring, the steel cable is in a clamped state, and the steel cable is clamped and locked at the appropriate height. The locking device has the beneficial effects that the structure is simple, and the height can be adjusted conveniently.
Description
Technical field
The utility model relates to a kind of locking device, specifically a kind of by cam handle control spring to the unclamping and clamp and adjust position of cable wire, then lock.
Background technique
According to using function needs, some article need to be adjusted height, and as desk, easel, worktable, article holder etc., the structural design of adjusting height is unreasonable, can increase cost, or make troubles to adjustment process.
Summary of the invention
The utility model provides a kind of locking device, is specifically a kind ofly by pressing cam handle, to control the clamp position of cable wire is realized locking and loosened, to adjust the height of object.
The solution the utility model proposes is: the circular hole by cable wire through housing, and by pressing cam handle control, the clamp position of cable wire is realized locking and loosened, to adjust the height of object.
The utility model comprises housing, axle, spring, cam handle etc., changes spring the state of a control of cable wire is realized locking and unclamped by cam handle.Specifically by following structure, realize: in housing, have the structure of shoulder hole, with installation shaft and spring; On housing front and rear wall and on axle, there is through hole, in order to whippletree to be installed and to guarantee the side-to-side movement of whippletree; Housing right side has vertical through hole to pass for cable wire; Cam handle is connected with housing with hinge, and elastic force resistance sheet two ends are connected with housing and cam handle respectively, to guarantee the stationarity of cam handle motion.
Adopt the locking device after such scheme, press cam handle during use, whippletree promotes spring, and spring, in compressive state, now axially moves left, and cable wire is in free state, and with hand propulsion, locking device can move along cable wire, adjusts height; Unclamp cam handle, the elastic force effect of spring makes axially to move right, and cable wire, in clamp position, is locked in proper height.
The beneficial effect of this model utility is, simple in structure, can adjust easily height.
Accompanying drawing explanation
Below in conjunction with Figure of description, the utility model is described.
The schematic appearance that accompanying drawing 1 is locking device
The horizontal projection sectional view that accompanying drawing 2 is locking device, now cable wire is in clamp position.
Fig. 3 is the horizontal projection sectional drawing of locking device, and now cable wire is in free state, and device can move up and down.
1. cam handles in figure, 2. housing, 3. axle, 4. spring, 5. cable wire, 6. whippletree, 7. elastic force resistance sheet, 8. hinge
Embodiment
In Fig. 2, spring and axle (3) are packed in the shoulder hole of housing (2), hole by whippletree (6) through axle (3) and housing (2) front and back, cam handle (1) is connected with housing (2) with hinge (8), elastic force is hindered to sheet (7) and be fixed on cam handle (1) above, cable wire (5) is vertically through the cylindrical hole on housing (2).During use, press cam handle, whippletree (6) promotes spring (4), and spring (4) is in compressive state, and axle (3) moves to left, and now cable wire is in free state, removable with hand propulsion locking device; Unclamp cam handle, the elastic force effect of spring makes axially to move right, and clamping cable wire, is locked in proper height.
Claims (2)
1. a locking device, comprise housing, axle, spring, cam handle, whippletree, elastic force resistance sheet, hinge, its feature by cam handle, change spring to the state of a control of cable wire realize locking and unclamp, in housing, have the structure of shoulder hole, so that multidiameter shaft and spring to be installed; On housing front and rear wall and axle, there is through hole, whippletree is installed and is guaranteed the side-to-side movement of whippletree; Housing right side has vertical through hole to pass for cable wire; Cam handle is connected with housing with hinge, and elastic force resistance sheet two ends are connected with housing and cam handle respectively.
2. locking device according to claim 1, the slightly larger in diameter in its feature hole on housing is in the diameter of cable wire; Housing shoulder hole each several part slightly larger in diameter is in the diameter of the corresponding part of axle.
