Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to a manual hoist is with connection structure who pulls out chain piece and wallboard belongs to manual hoist annex technical field.
[ background of the invention ]
When the hoisting chain works, the chain links connected with the ring rings need to be separated from the chain sockets of the hoisting chain wheel in sequence, and the chain blocking block (also called as a chain pulling block) can play a role in enabling the chain links to be separated smoothly and orderly so as to avoid the chain links from stacking faults.
The existing chain-releasing mechanism consists of a chain blocking block, a pin shaft and a supporting rod, wherein the chain blocking block is provided with an upper through hole and a lower through hole, the pin shaft and the supporting rod sequentially penetrate through the upper through hole and the lower through hole, two ends of the pin shaft movably penetrate through two wallboards, two ends of the supporting rod are fixedly connected to the two wallboards, and the supporting rod is arranged in a matched manner with the pin shaft, so that the chain blocking block is actuated, and the working position of the chain blocking block is ensured to be always positioned on the inner side of.
Careful analysis of the above structure has revealed the following disadvantages:
the chain-releasing mechanism is composed of three parts which are arranged in a split mode, and after the chain-releasing mechanism is assembled, the pin shaft and the supporting rod are required to be installed on the two wall plates respectively, so that the defect that the installation efficiency is low exists.
[ Utility model ] content
The to-be-solved technical problem of the utility model is to the not enough of above-mentioned prior art existence and provide a connection structure of chain piece and wallboard is used with pulling out to hand block, pull out chain piece simple to operate, work efficiency height, can avoid rotating for the wallboard.
Therefore, the utility model provides a technical scheme that above-mentioned technical problem adopted as follows:
the connection structure of chain piece and wallboard is pulled out with pulling out to chain block for hand block, including a left wallboard, a right wallboard and one have the chain piece body of pulling out the chain head, its improvement point lies in: the left shaft head and the right shaft head are respectively extended out of the left end and the right end of the chain pulling block body, so that the left shaft head, the left shaft head and the chain pulling block body are an integral piece, the cross sections of the left shaft head and the right shaft head are both D-shaped, and the left shaft head and the right shaft head are both hollow and are respectively communicated with the chain pulling block body; the left wall plate and the right wall plate are respectively provided with a D-shaped through hole; the left shaft head and the right shaft head are respectively penetrated in the D-shaped through hole of the left wallboard and the D-shaped through hole of the right wallboard.
The left shaft head and the pull chain block body are provided with a left shaft shoulder therebetween, the right shaft head and the pull chain block body are provided with a right shaft shoulder therebetween, the left shaft shoulder abuts against the inner wall surface of the left wallboard, and the right shaft shoulder abuts against the inner wall surface of the right wallboard.
The distance between the left shaft shoulder and the right shaft shoulder is used for controlling the distance between the left wallboard and the right wallboard, so that the left wallboard and the right wallboard are reliably positioned.
The chain pulling head protrudes from the chain pulling block body in the middle.
The utility model has the advantages as follows:
save two parts of prior art round pin axle, bracing piece, abandoned prior art fender chain piece, round pin axle and bracing piece and for the components of a whole that can function independently configuration structure, changed and adopted left spindle nose, left spindle nose and pull out the chain piece body and be an overall structure spare, not only reduced the quantity of part, moreover overall structure part the utility model discloses simple to operate and work efficiency are high.
The cross section of the left shaft head and the cross section of the right shaft head are respectively in a D shape matched with the through hole of the left wallboard and the through hole of the right wallboard, and the connecting structure can fully limit the rotation of the chain pulling block relative to the two wallboards, so that the requirement that the chain links of the hoisting chain are reliably separated is met.
[ description of the drawings ]
The present invention will be described in further detail with reference to the accompanying drawings.
FIG. 1 is a view showing the appearance of the chain pulling block of the present invention;
FIG. 2 is a schematic view of the chain pulling block of the present invention;
fig. 3 is a plan view of the left (right) wall panel.
[ detailed description ] embodiments
Please refer to fig. 1, 2 and 3, which illustrate a preferred embodiment of the present invention.
Chain block and wallboard's connection structure is pulled out with pulling out to manual block, including a left wallboard B1, a right wallboard B2 and one have pull out chain block body 1 of chain head 11, its improvement point lies in: the left shaft head 2 and the right shaft head 3 extend out of the chain pulling block body 1 at the left end and the right end respectively, so that the left shaft head 2, the right shaft head 3 and the chain pulling block body 1 are an integral piece, the cross sections (radial directions) of the left shaft head 2 and the right shaft head 3 are both D-shaped, and the left shaft head 2 and the right shaft head 3 are both hollow and are communicated with the chain pulling block body 1 respectively; the left wall plate B1 and the right wall plate B2 are respectively provided with a D-shaped through hole B10 and a D-shaped through hole B20; the left shaft head 2 and the right shaft head 3 are respectively arranged in a D-shaped through hole B10 of the left wall board B1 and a D-shaped through hole B20 of the right wall board B2 in a penetrating way.
