Abstract
The utility relates to a wedge-shaped self-locking device comprising a wedge-shaped insert block and a locking frame. The locking frame comprises a cross beam, two support arms, two clamping arms and two elastic devices. The support arms are connected to two ends of the cross beams, one ends of the clamping arms are hinged to the cross beam, while the other ends of the clamping arms face to the direction of the wedge-shaped insert block. The clamping arms correspond to each other, and free ends of the same form a wedge-shaped guiding inlet which is matched with the wedge-shaped insert block in shape when the clamping arms draw close to each other. One ends of the elastic devices are connected to the support arms, while the other ends of the elastic devices are connected to the clamping arms to exert force to the same toward a center shaft of the locking frame. When required to be locked, the wedge-shaped insert block, is only needed to be inserted between the clamping from the wedge-shaped guiding inlet formed between the clamping arms; and meanwhile, when required to be unlocked, the wedge-shaped insert block is only needed to be pulled out with strength. The wedge-shaped self-locking device has the advantages that both locking and unlocking are quick and convenient.
Description
Technical field
The utility model relates to a kind of locking device, especially relates to a kind of wedge shape self-locking device.
Background technique
In engineering machinery field, consider Security and operational safety requirement, there are a lot of equipments unit to lock.Current engineering machinery generally adopts bolt to carry out the locking of equipment unit, installs, dismantles inconvenient shortcoming but exist in actual applications.Especially in case of emergency need the device of the state of devoting oneself to work immediately, can not realize quick release and locking when connecting with bolt, had a strong impact on working efficiency, may cause unexpected the generation.Therefore, how to design can quick release and the device of locking, becomes the technical problem that those skilled in the art need to be resolved hurrily.
Summary of the invention
The purpose of this utility model is for the problems referred to above, and a kind of wedge shape self-locking device is provided, and has solved the existing technical problem of prior art.
for achieving the above object, the utility model has adopted following technical proposal: a kind of wedge shape self-locking device, it comprises wedge shape inserted block and locking rack, described locking rack comprises crossbeam, two support arms, two jig arm and two elastic devices, described two support arms are connected to the two ends of described crossbeam, one end of each described jig arm is hinged on described crossbeam, the other end is towards the direction of described wedge shape inserted block, the position of two described jig arm is relative, and when two jig arm are closed up, the free end of described two jig arm forms the wedge shape introducing port that matches with the shape of described wedge shape inserted block, one end of described elastic device is connected on described support arm, the other end is connected on described jig arm, apply power towards the locking rack central shaft to described jig arm.
In above-mentioned wedge shape self-locking device, preferably, the end of described wedge shape inserted block also is hinged with movable axis.
In above-mentioned wedge shape self-locking device, preferably, described elastic device is Compress Spring.
In above-mentioned wedge shape self-locking device, preferably, the back side of each jig arm is provided with the first maintainance block, is provided with second maintainance block corresponding with this first maintainance block position on corresponding support arm, and described elastic device passes described the first maintainance block and the second maintainance block.
In above-mentioned wedge shape self-locking device, preferably, the front of each described jig arm has projection, is formed with the inclined-plane that matches with described wedge shape inserted block shape on the inner surface of described projection.
In the time will locking the wedge shape inserted block, only need firmly the wedge shape inserted block to be inserted between two jig arm from the wedge shape introducing port that forms between two jig arm to get final product.When wanting release, only need firmly extract the wedge shape inserted block and get final product, so this wedge shape self-locking device has and locks and release characteristics very quickly and easily all.
Description of drawings
Fig. 1 is the structural representation of the wedge shape self-locking device that provides of the utility model embodiment.
Embodiment
Please refer to Fig. 1, the wedge shape self-locking device that the utility model embodiment provides comprises wedge shape inserted block 22 and locking rack.
Locking rack comprises crossbeam 11, two support arms 12, two jig arm 13 and two elastic devices 14.Two support arms 12 are connected to the two ends of crossbeam 11.One end of each jig arm 13 is hinged on crossbeam 11 by bearing pin 131, and the other end is towards the direction of wedge shape inserted block 22.The position of two jig arm 13 is relative, and two jig arm 13 are when closing up, and the free end of two jig arm 13 forms the wedge shape introducing port that matches with the shape of wedge shape inserted block 22, makes wedge shape inserted block 22 easily between two jig arm 13 of insertion.One end of elastic device 14 is connected on support arm 12, and the other end is connected on jig arm 13, applies power towards the locking rack central shaft to jig arm 13.
In the time will locking wedge shape inserted block 22, only need firmly wedge shape inserted block 22 to be inserted between two jig arm 13 from the wedge shape introducing port that forms between two jig arm 13, two jig arm 13 are under the pressure-acting of elastic device 14, with 22 lockings of wedge shape inserted block.Certainly, also locking device can be set further, with 13 lockings of two jig arm, can play better locking effect.When wanting release, only need firmly extract wedge shape inserted block 22 and get final product, so this wedge shape self-locking device has and locks and release characteristics very quickly and easily all.
Particularly, in the present embodiment, elastic device 14 is Compress Spring.
In a preferred embodiment, the end of wedge shape inserted block 22 also is hinged with movable axis 21, makes this wedge shape self-locking device can be installed more neatly.
In a preferred embodiment, the back side of each jig arm 13 is provided with the first maintainance block 15, is provided with second maintainance block 16 corresponding with this first maintainance block 15 positions on corresponding support arm 12, and elastic device 14 passes the first maintainance block 15 and the second maintainance block 16.The first maintainance block 15 and the second maintainance block 16 can be supported mutually when wedge shape inserted block 22 inserts between two jig arm 13, thereby jig arm 13 is kept in position.
Particularly, in the present embodiment, the front of each jig arm 13 has projection 132, is formed with the inclined-plane that matches with wedge shape inserted block 22 shapes on the inner surface of projection 132, so that wedge shape inserted block 22 can be extracted relatively easily when release.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
