Embodiment

Below in conjunction with attached drawing, a preferred embodiment to the utility model elaborates.But the guarantor of the utility model Shield scope is not limited to following embodiments, i.e., is made in every case with present utility model application the scope of the claims and description simple Equivalent changes and modifications, all still belongs within the utility model patent covering scope.

Refering to Fig. 1-4, for a kind of soft elastic hook described in the utility model, including it is handle 1, contiguous block 2, hook 3, slow Device and a pair of of guide post 4 are rushed, the lower end of handle is fixed on the upper side of contiguous block, and the upper end of a pair of of guide post is individually fixed in connection On the downside of block, the axisymmetrical distribution of a pair of of guide post opposite handle；The upper end of hook is interval with a pair of of guide sleeve 5, a pair of Guide sleeve is movably set on a pair of of guide post respectively, and each guide post is located at below guide sleeve is arranged with spring 6 respectively, under each guide post End is respectively fixed with stop nut 7, and spring is spacing, and gasket 8 is equipped between stop nut and spring.The fixation of buffer End is fixed on the contiguous block, and buffering end is fixed on the hook.

Wherein, buffer includes the fixing end of buffer A 9 and buffer B 10, buffer A and buffer B and fixes respectively In the left side of contiguous block and right side, the buffering end of buffer A and buffer B are individually fixed in the left side and right side of hook.Connection The left side of block is equipped with buffer fixed block 12, and the fixing end of buffer A is fixed on the buffer fixed block.The right side of contiguous block Side is equipped with through hole, and buffer B is arranged in through hole.The lower end of hook is equipped with two suckers 11.Contiguous block, guide post, spring and anti- The outside of loose nut is equipped with protective cover.

In assembling, contiguous block is fixedly connected soft elastic hook with handle by pin and limiting slot, and buffer is fixed Block is fixedly connected by screw with contiguous block, and hydraulic bjuffer A is fixed on buffer contiguous block, and buffer B is fixed on connection On block.Guide sleeve is installed in the guide sleeve mounting hole of hook.Gasket and stop nut are installed on guide post, are then inserted in compression bullet Spring, then the upper end of guide post is fixed on contiguous block by the component as shown in Figure 1 through the guide sleeve of hook, same mode will Another gasket and stop nut are installed on another guide post, are then inserted in compression spring, then by the component as shown in Figure 1 through extension Another guide sleeve of hook, the upper end of guide post is fixed on contiguous block.Two suckers are installed on hook again, finally installation protection Cover.Buffer A, B play the role of damping, prevent spring exciting, and adjust hook translational speed.Spring plays the work of accumulation of energy With when loading reduction, release elastic potential energy, plays the role of partial buffer.

The soft elastic is linked up with, and the effect of elasticity is realized by two springs, is come by adjustable two buffers A, B is damped Regulation elasticity damps, when realizing to elastic hook load change, hook and the adjusting of contiguous block spacing pace of change.Pass through selection Buffer A, B of the adjustable damping of the spring and different size of different coefficient of elasticity change model to be applicable in different loads Enclose, and the requirement to buffering effect.

When hook does not load, original state is as shown in Fig. 2, compression spring is in elongation state, hook and contiguous block Fitting, when hook has load, links up with and is separated as shown in Figure 3,4 with contiguous block under the action of load.Due to the effect of load, Spring-compressed spring produces elastic potential energy.When the load decreases, the pressure reduction to spring is linked up with, elastic potential energy of the spring discharges, Play the role of partial buffer.

As shown in Figure 5,6, carry certain brand all-in-one machine using the hook to be analyzed as example, it is assumed that all-in-one machine connects with pallet Speed before touching is V, and the quality of all-in-one machine is M, due to there is vacuum cup to be attracted with all-in-one machine above hook, in all-in-one machine and stack When plate contacts, with all-in-one machine and hook together for research object, all-in-one machine and hook are subject to frictional force f1, gravity G, spring at this time Make a concerted effort F4, the impact force F2 of pallet of elastic force F3, buffer A, B, it is as follows to obtain formula according to momentum theorem：

MV=(F2+F3-G-F4) * t. analyses understand that mass M, gravity G, can not change, and F4 can be by adjusting buffer A, B adjusts its size, and in order to reduce F2, it is upward to be adjustable to F4 directions.Therefore, can be with to reduce the size of Contact F2 By reducing speed V, either reduce F4 or increase F3.When nonelastic buffering, F3 and F4 are zero, and time t has increased Greatly, therefore soft elastic hook can play the role of reducing impact force F2, and certain protective effect is played to product.

, when product is more sensitive to impact force, usually adopted generally using rigid executing agency when carrying product at present Taking reduces transporting velocity V and makes pallet using softer material.But the reduction of work efficiency that the reduction of speed is brought, make Pallet is made with softer material, product will be brought to be in place the not high hidden danger of positioning accuracy, therefore, this patent describes soft Elastic hook, to solve above-mentioned technological difficulties, there is provided foundation.

It can be seen from the above that the soft elastic is linked up with by setting a pair of of spring to realize elastic effect on hook, can by damping The buffer of tune carrys out regulation elasticity damping, when realizing to elastic hook load change, hook and contiguous block spacing pace of change Adjust, reduce to the impact force of product when carrying product, so as to protect product, there is the advantages that simple in structure, easy to use.
