The utility model discloses a realize through following technical scheme:
the utility model provides an internal stay hoist with locking function which characterized in that includes: a suspender, an internal supporting component and a sliding block sleeved on the suspender,
the upper section of the suspender is provided with a guide long hole, a guide rod sliding along the guide long hole is inserted into the guide long hole,
the inner support assembly comprises L-shaped clamping jaws symmetrically arranged on two sides of the sliding block and hinged with the sliding block, a contact block hinged with the lower end of the L-shaped clamping jaw and connecting rods arranged between the upper end of the L-shaped clamping jaw and the guide rod, two ends of each connecting rod are respectively hinged with the guide rod and the L-shaped clamping jaw, a locking rod is arranged between the two connecting rods, one end of each locking rod is hinged with one connecting rod, the other end of each locking rod is provided with a locking groove, the other connecting rod is provided with a locking pin corresponding to the locking groove, an impact column is fixedly connected onto the hanging rod, when the locking groove on the locking rod is locked with the locking pin, the impact,
the lower end of the suspender is provided with a plurality of step platforms, the diameter of the upper end face of each step platform is smaller than that of the lower end face of each step platform, a spring piece corresponding to each step platform is arranged in each slider, one side, close to the suspender, of each spring piece is an inclined plane corresponding to each step platform, and the upper end face of each spring piece is a plane corresponding to the lower end face of each step platform.
The utility model has the advantages that:
the utility model provides an internal stay hoist can drive contact block and product inner chamber lateral wall in close contact with through L type jack catch when the product that has the inner chamber is hoisted to hoist, and simultaneously, the auto-lock can be realized with the spring leaf to the stair platform under the frictional force effect, prevents to rock the danger that makes not hard up between contact block and the product cause the product to drop, has improved stability and factor of safety.
Drawings
Fig. 1 is a schematic view of the structure of the present invention.
In the figure: 1. the spring piece comprises a suspension rod, 2 sliding blocks, 3 guide long holes, 4 guide rods, 5L-shaped clamping claws, 6 contact blocks, 7 connecting rods, 8 locking rods, 9 locking grooves, 10 locking pins, 11 impact columns, 12 step platforms and 13 spring pieces.
Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.
As shown in the figure, the utility model discloses a: a suspender 1, an internal bracing component and a slide block 2 sleeved on the suspender,
the upper section of the suspender is provided with a guide long hole 3, a guide rod 4 sliding along the guide long hole is inserted into the guide long hole,
the inner support component comprises L-shaped clamping jaws 5 symmetrically arranged on two sides of the sliding block and hinged with the sliding block, contact blocks 6 hinged with the lower ends of the L-shaped clamping jaws and connecting rods 7 arranged between the upper ends of the L-shaped clamping jaws and the guide rods, the openings of the L-shaped clamping jaws are arranged outwards, two ends of each connecting rod are respectively hinged with the guide rods and the L-shaped clamping jaws, a locking rod 8 is arranged between the two connecting rods, one end of each locking rod is hinged with one connecting rod, the other end of each locking rod is provided with a locking groove 9, the other connecting rod is provided with a locking pin 10 corresponding to the locking groove, an impact column 11 is fixedly connected onto the suspender, when the locking groove on the locking rod is locked with the locking pin, the impact column is positioned above the locking rod, before the lifting appliance in the embodiment is placed into an inner cavity of a product, the two contact blocks are firstly close to tightly clamp the locking groove on the locking rod with the, the further descending of the slide block is blocked due to the action of the locking rod, the pre-locking of the lifting appliance is completed, the distance between the two contact blocks is smaller than the diameter of the inner cavity of the product, the contact blocks can be smoothly placed into the inner cavity of the product, the lifting appliance continues to descend, the guide rod moves upwards along the guide long hole along with the descending of the suspension rod after the contact blocks are contacted with the ground, the impact column collides with the locking rod, the locking groove of the locking rod is separated from the locking pin, the unlocking is realized, the slide block continues to slide downwards under the action of gravity due to the fact that the limitation of the locking rod is not existed, the guide rod moves to the lowest end of the guide long hole and cannot continue to move downwards, the slide block continues to move downwards, the included angle between the connecting rod and the vertical part of the L-shaped clamping jaw is enlarged, the contact blocks are in close contact with the side wall of the inner cavity of the product, the lifting, the L-shaped clamping jaw is driven to rotate to pull the connecting rod and the sliding block downwards, the included angle between the connecting rod and the vertical part of the L-shaped clamping jaw is further enlarged, meanwhile, the contact block is more tightly contacted with the side wall of the inner cavity of the product, and the locking between the lifting appliance and the product is completed under the action of the friction force between the contact block and the product and the self gravity of the sliding block, so that the product is lifted,
the lower extreme of jib is equipped with a plurality of terraces 12, the up end diameter of terraces is less than the lower terminal surface diameter, be equipped with the spring leaf 13 that corresponds with the terraces in the slider, the spring leaf is close to jib one side and is the inclined plane that corresponds with the terraces, and the up end of spring leaf is the plane that corresponds with terminal surface under the terraces, and when lifting equipment upwards spurs the hoist, the slider slides down along the jib, and the terraces touching spring leaf of jib hypomere is gone up smoothly to the terraces, under the effect of spring leaf inclined plane and terraces lateral wall, the terraces can upwards pass through the spring leaf smoothly, but terminal surface under the terraces and the spring piece up end be the plane, because the terraces can't pass through the spring leaf downwards by oneself to realize the locking of unidirectional motion between jib and the slider, avoid rocking to make the slider move down and cause to be connected.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
