Description
Technical field
The utility model relates to a kind of construction plant device field, particularly a kind of lowering or hoisting gear.
Background technique
Often a kind of device of intermittent movement can be needed in industry to carry out satisfied specific motion needs; such as lift adjustment among a small circle; the device that can complete this motor task in present stage industry is fewer; and existing apparatus design is all relatively complicated; process for machining and manufacturing also relative difficulty is larger, and manufacture cost is also relatively large.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of lowering or hoisting gear, and this mechanism can provide a kind of easy intermittent lifting device.
The object of model utility is achieved in that
A kind of lowering or hoisting gear, it comprises lifting bar and control volume, and lifting bar runs through control volume inside and is flexibly connected with control volume.
The described lifting bar left and right sides is equidistantly provided with multiple profile of tooth block, and front and rear surfaces is provided with restraining groove.
Described control volume comprises box-like body, box-like body front and rear surfaces runs through and is provided with two limited wheels, is provided with laborsaving seesaw, is provided with coil tension spring below laborsaving seesaw on the right side of box-like body, on the right side of box-like body, inwall is provided with cantilever latch, runs through inwall on the right side of box-like body and be provided with resilient key above cantilever latch.
Laborsaving seesaw and cantilever latch one end of described control volume are arc-shaped coupler body, and resilient key is provided with stiffness spring.
The utility model has following beneficial effect:
The utility model adopts above-mentioned design, can provide a kind of easy intermittent lifting device.Artificially firmly pull laborsaving seesaw downwards, the coil tension spring of laborsaving seesaw stretching lower end, the move upward lower end of the profile of tooth block hooking lifting bar side of the arc-shaped coupler body of laborsaving seesaw one end moves upward together, lifting bar also moves upward thereupon, when lifting bar moves to certain height, profile of tooth block is affiliated to after in the cantilever latch of box-packed body inwall, people stops to power, laborsaving seesaw sets back under the elastic force of coil tension spring, so far a cycle of motion terminates, artificially so repeatedly pull laborsaving seesaw, just the motion that lifting bar interval rises can be realized, when needs lifting bar declines, only need promote the resilient key on the right side of box-like body, touch the profile of tooth block of being affiliated in cantilever latch to be separated with cantilever latch, just can realize lifting bar to decline, structure is simple, easy and simple to handle, practical.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is structural representation front view of the present utility model.
Fig. 2 is structural representation side view of the present utility model.
In figure: lifting bar 1, profile of tooth block 1-1, restraining groove 1-2, control volume 2, box-like body 2-1, limited wheel 2-2, laborsaving seesaw 2-3, coil tension spring 2-4, cantilever latch 2-5, resilient key 2-6, stiffness spring 2-7.
Embodiment
Below in conjunction with accompanying drawing, mode of execution of the present utility model is described further.
Have see installation concrete in Fig. 1-2, figure and Placement, lifting bar 1 and control volume 2, lifting bar 1 runs through control volume 2 inside and is flexibly connected with control volume 2.
Described lifting bar 1 left and right sides is equidistantly provided with multiple profile of tooth block 1-1, and front and rear surfaces is provided with restraining groove 1-2.
Described control volume 2 comprises box-like body 2-1, box-like body 2-1 front and rear surfaces runs through and is provided with two limited wheel 2-2, laborsaving seesaw 2-3 is provided with on the right side of box-like body 2-1, coil tension spring 2-4 is provided with below laborsaving seesaw 2-3, on the right side of box-like body 2-1, inwall is provided with cantilever latch 2-5, runs through inwall on the right side of box-like body 2-1 and be provided with resilient key 2-6 above cantilever latch 2-5.
The laborsaving seesaw 2-3 of described control volume 2 and cantilever latch 2-5 one end are arc-shaped coupler body, and resilient key 2-6 is provided with stiffness spring 2-7.
Device specific works process of the present utility model and principle are:
Fig. 1-2 is illustrated with reference to integral installation distribution structure, adopt said structure, artificially firmly pull laborsaving seesaw 2-3 downwards, the coil tension spring 2-4 of laborsaving seesaw 2-3 stretching lower end, the move upward lower end of the profile of tooth block 1-1 hooking lifting bar 1 side of the arc-shaped coupler body of laborsaving seesaw 2-3 one end moves upward together, lifting bar 1 also moves upward thereupon, when lifting bar 1 moves to certain height, profile of tooth block 1-1 is affiliated to after on the cantilever latch 2-5 of box-packed body 2-1 inwall, people stops to power, laborsaving seesaw 2-3 sets back under the elastic force of coil tension spring 2-4, so far a cycle of motion terminates, artificially so repeatedly pull laborsaving seesaw 2-3, just the motion that lifting bar 1 interval rises can be realized, when needs lifting bar 1 declines, only need promote the resilient key 2-6 on the right side of box-like body 2-1, touch the profile of tooth block 1-1 be affiliated on cantilever latch 2-5 to be separated with cantilever latch 2-5, just can realize lifting bar 1 to decline, structure is simple, easy and simple to handle, practical.
