Abstract
The invention discloses a plug pin which comprises a pin shaft, wherein a sleeve is arranged at one end of the pin shaft, and a clamping block is arranged on the inner wall of the sleeve and is clamped with an L-shaped clamping groove formed in the outer wall of the pin shaft, or an L-shaped clamping groove is formed in the inner wall of the sleeve and is clamped with a clamping block arranged on the outer wall of the pin shaft. The plug pin is high in breakage resistance, long in service life, and capable of ensuring firm connection between a soft tray and a conveying chain and guaranteeing the stability and safety of work of a lifter.
Description
Technical field
The present invention relates to component of machine field, be specifically related to a kind of latch.
Background technique
The soft pallet of lift is rising, and particularly, when turning, two circulation link chains above need to draw soft pallet, makes it complete the action of rising and crooked route.Now before soft pallet, the chain of tie point is asynchronous with the chain of tie point below, chain is stressed and two chains are stressed inconsistent below to cause before soft pallet two, before stressed excessive, and then easily cause the fixedly latch distortion of chain and soft pallet, or latch fracture, affects working stability and the Security of lift.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide that a kind of resistance to fracture is strong, long service life, guarantee the latch being connected firmly between soft pallet and transmission chain.
To achieve these goals, the technical solution used in the present invention is:
This latch, comprises bearing pin, in described bearing pin one end, is provided with sleeve, at described sleeve lining, is provided with fixture block and the set L-type draw-in groove phase clamping of described bearing pin outer wall or establishes L-type draw-in groove and the clamping of the set fixture block phase of described bearing pin outer wall at described sleeve lining.
Described sleeve is connected by locating stud with described bearing pin.
Described fixture block and described L-type draw-in groove are two pairs, and these two pairs of fixture blocks and L-type draw-in groove be corresponding being located on the both sides of the pin-and-hole that described locating stud is installed on described sleeve and described bearing pin respectively.
On the other end of described bearing pin, be provided with the axle cap being pressed on described Transmitted chains outside.
Described axle cap is disc structure.
The invention has the advantages that: this latch, bearing pin one end is provided with bearing pin and forms the sleeve that falcon groove coordinates, and the break resistance of latch is strong, and increase working life, soft pallet is located between bearing pin upper bush inner side and the bearing pin the other end, and the connectivity robustness between soft pallet and chain is good.In lift work process, the axle cap of bearing pin one end is pressed on chain simultaneously, and bearing pin is not directly subject to the impacts such as chain extruding, has further extended the working life of latch.This latch, not only resistance to fracture is strong, long service life, and can guarantee to be connected firmly between soft pallet and transmission chain; Can avoid latch directly easily to rupture fixedly time, cause soft pallet to tilt, the problem that causes soft pallet to drop, has guaranteed working stability and the Security of lift.
Accompanying drawing explanation
The content of below each width accompanying drawing of specification of the present invention being expressed and the mark in figure are briefly described:

Embodiment
Contrast accompanying drawing below, the description by optimum embodiment, is described in further detail the specific embodiment of the present invention.
As shown in Figure 1 to Figure 3, this latch, comprise bearing pin 10, in bearing pin 10 one end, be provided with sleeve 20, at sleeve 20 inwalls, be provided with fixture block 22 and the bearing pin set L-type draw-in groove 12 phase clampings of 10 outer wall or establish L-type draw-in groove 12 and the set fixture block 22 phase clampings of bearing pin 10 outer wall at sleeve 20 inwalls.The L-type fixture block structure that fixture block 22 is and L-type draw-in groove 12 matches, fixture block 22 is stuck in L-type draw-in groove 12, forms falcon groove and coordinate between the two.When fixture block 22 is stuck in L-type draw-in groove 12, sleeve 20 inwalls and bearing pin 10 outer wall phase clampings.
In one end of bearing pin 10, add a sleeve 20, and the falcon groove forming by the L-type draw-in groove 12 on the fixture block 22 on the L-type draw-in groove 12 on bearing pin 10 and sleeve 20 inwalls or the fixture block 22 on bearing pin 10 and sleeve 20 inwalls coordinate realize the two between be connected, the soft pallet that bearing pin 10 will be fixed so just can be fastened between bearing pin 10 the other ends and sleeve 20.And due to sleeve 20 can in the L-type draw-in groove 12 of bearing pin 10, push by fixture block 22 again card lean against in the cell wall of L-type draw-in groove 12, can effectively prevent bearing pin 10 because transmit the asynchronous bearing pin causing 10 fractures between soft pallet and transmission chain, thereby guarantee to be connected between soft pallet and transmission chain.
Further, radially traversing in order to prevent the generation of the position between the two under external force of bearing pin 10 and sleeve 20, further guarantee the connective stability between soft pallet and transmission chain; On bearing pin 10 and sleeve 20, be also respectively equipped with corresponding pin-and-hole I 11 and pin-and-hole II 21, in pin-and-hole I 11 and pin-and-hole II 21, plug the locating stud of fixing the two, sleeve 20 is also connected by locating stud with bearing pin 10.
For further guarantee to be connected between bearing pin 10 and sleeve 20 firmly, avoid the two to be offset under external force simultaneously, cause the slippage of sleeve 20; L-type draw-in groove 12 is made as two pairs with fixture block 22, and correspondence is arranged in the periphery and sleeve 20 inwalls of bearing pin 10 respectively, and lays respectively on pin-and-hole I 11 and pin-and-hole II 21 both sides.Be that fixture block 22 and L-type draw-in groove 12 are two pairs, these two pairs of fixture blocks 22 and L-type draw-in groove 12 be corresponding being located on the both sides of the pin-and-hole that locating stud is installed on sleeve 20 and bearing pin 10 respectively.
Further, the other end of bearing pin 10 is provided with axle cap 13, and preferably axle cap 13 is disc structure.Specifically, the axle cap 13 of disc structure is arranged on transmission chain one side, because bearing pin 10 is to pass from the chain link of transmission chain, so the axle cap of bearing pin 10 can be pressed against the chain link outside of transmission chain, thereby guarantee that bearing pin 10 does the used time being subject to soft pallet pulling force, axle cap 13 can be pressed on transmission chain, thereby makes transmission chain and soft pallet keep being synchronized with the movement, reduce the pulling force that bearing pin 10 is subject to, avoid it to be pulled off or rupture.
Obviously specific implementation of the present invention is not subject to the restrictions described above, as long as adopted the improvement of the various unsubstantialities that method design of the present invention and technological scheme carry out, all within protection scope of the present invention.
