Abstract
A quick-release shackle is mainly composed of a shackle body (1), a shackle pin shaft (2), a pin shaft check block (3) and an elastic cylindrical pin (4). The shackle body (1) is U-shaped, the shackle pin shaft (2) is inserted into a pin hole of the shackle body (1), the tail end of the shackle pin shaft (2) is provided with a pin shaft check block groove, the pin shaft check block (3) is inserted into the pin shaft check block groove, a sliding movable groove is arranged in the middle of the pin shaft check block (3), and the elastic cylindrical pin (4) is inserted into the sliding movable groove. The pin shaft check block is connected with the pin shaft, the width size of the pin shaft check block (3) is less than the size of the pin hole of the shackle body (1), and pin shaft check block (3) is enabled to penetrate through the pin hole. The quick-release shackle has the advantages that the quick-release pin shaft check block is arranged at the tail end of the pin shaft, and the pin shaft check block only needs to be moved and rotate for 90 degrees so as to achieve the locking and demounting of the pin shaft; the quick-release shackle is simple and practical in structure, easy to process and manufacture, low in cost, and shorter in installation and demounting time of the shackle, and working efficiency is further improved.
Description
Technical field
The utility model relates to a kind of quick-release shackle, belongs to the lifting machine field.
Background technology
Owing to developing rapidly of lifting industry, more and more higher to the requirement of hoisting rig and attaching parts, requirement safety, quick realization connect hanging object and dismantle.Patent CN202022653U has introduced a kind of fast shackle, to be front end cooperate with the second circular hole outer face upper groove after unloading front and back two circular holes (the second circular hole is with catching groove) on the button with the inserted link of back-off this technology, realize fast loading and unloading, increase work efficiency.This technology has the following disadvantages: 1) unload the difficult processing of catching groove on button the second hole; 2) the catching groove place easily forms the concentrated shackle intensity that affects of stress.2) after strengthening, the shackle weight classes has certain difficulty because the complexity of hinge pedestal structure is loaded and unloaded.
Patent CN2539878Y has introduced another kind of fast shackle, and it mainly is comprised of shackle body and lateral pin, the mobile stay cord that drives of the moving handle on the lateral pin, the opening and closing of then controlling lock dog realize fast loading and unloading, have save time, the labour-saving characteristics.The maximum deficiency of this technology is complex structure, processes the loaded down with trivial details productive costs that causes and improves.
The utility model content
The purpose of this utility model is for the problems referred to above, and a kind of quick-release shackle simple in structure, easy to use is provided.
The purpose of this utility model is to be achieved through the following technical solutions:
Quick-release shackle, quick-release shackle mainly are comprised of shackle body, shackle bearing pin, bearing pin block, elastic cylindrical pin, cylinder block and spring.Described shackle body takes the shape of the letter U, the shackle bearing pin inserts in the pin-and-hole of shackle body, the shackle pin shaft end has bearing pin block groove, the centre-drilling hole of bearing pin block trench bottom, mounting spring and cylinder block in the hole, held out against by spring promotion cylinder block and described bearing pin block, the bearing pin block inserts in the bearing pin block groove, middle part at the bearing pin block has slippage slot, insert in the described slippage slot with elastic cylindrical pin, bearing pin block and shackle bearing pin are linked together, and the width dimensions of described bearing pin block passes from described pin-and-hole to allow described bearing pin block less than the size of the pin-and-hole of shackle body.Spring and cylinder block withstand the bearing pin block, so that the bearing pin block all can be fixed when locking state and detachable state.
The beneficial effects of the utility model are as follows:
1) at the bearing pin end Quick-release pin axle bumper piece is housed, only need move bearing pin block 90-degree rotation just can realize lock clasp and dismounting, simple and practical.
2) be easy to processing and manufacturing, cost is low.
2) the shackle loadingunloading time shorter, work efficiency further improves.
Description of drawings
The below is described in further detail the utility model with embodiment with reference to the accompanying drawings.
Fig. 1 is quick-release shackle locking state scheme drawing.
Fig. 2 is quick-release shackle disassembly status scheme drawing.
The specific embodiment
Shown in Fig. 1-2, the described quick-release shackle of the utility model embodiment, the quick-release shackle mainly is comprised of shackle body 1, shackle bearing pin 2, bearing pin block 3, elastic cylindrical pin 4, cylinder block 5 and spring 6.Described shackle body 1 takes the shape of the letter U, shackle bearing pin 2 inserts in the pin-and-hole of shackle body 1, shackle bearing pin 2 ends have bearing pin block groove, the centre-drilling hole of bearing pin block trench bottom, mounting spring 6 and cylinder block 5 in the hole, promoting cylinder block 5 by spring 6 holds out against with described bearing pin block 3, bearing pin block 3 inserts in the bearing pin block groove, middle part at bearing pin block 3 has slippage slot, insert in the described slippage slot with elastic cylindrical pin 4, bearing pin block and shackle bearing pin are linked together, and the width dimensions of described bearing pin block 3 passes from described pin-and-hole to allow described bearing pin block 3 less than the size of the pin-and-hole of shackle body 1.Spring and cylinder block withstand the bearing pin block, so that the bearing pin block all can be fixed when locking state and detachable state.
The beneficial effects of the utility model are as follows:
1) at the bearing pin end Quick-release pin axle bumper piece is housed, only need move bearing pin block 90-degree rotation just can realize lock clasp and dismounting, simple and practical.
2) be easy to processing and manufacturing, cost is low.
2) the shackle loadingunloading time shorter, work efficiency further improves.
