Abstract
A novel lifter support arm lock is mounted in a lifting pedestal of a lifter. One end of each support arm is connected in the lifting pedestal by a shaft. The support arm lock for each support arm comprises a tooth block provided with an engaging tooth. The upper surface of the tooth block is provided with a guide connection shaft, and the lower surface of the tooth block is provided with a ground connection shaft. The guide connection shaft and the ground connection shaft are respectively mounted in shaft holes of a top plate and a base plate of the lifting pedestal. A reset spring is mounted on the guide connection shaft. The ground connection shaft extends out of the lifting pedestal. The tooth block can move up and down in the lifting pedestal. The inner end of each support arm is provided with a connection plate, and the connection plate is provided with multiple tooth grooves allowing the embedment of the engaging tooth of the tooth block. The novel lifter support arm lock is simple in structure and easy to mount, and is capable of unlocking automatically when the lifting pedestal is landed and locking automatically when the lifting pedestal is rising without needing manual operation, thereby being convenient to use and preventing the forgetting problem. Moreover, the support arms of the lifter are locked during the vehicle lifting process so that the problems of vehicle dropping, property loss, and personnel casualty are prevented.
Description
Technical field
The utility model relates to a kind of lockout mechanism, specifically, is a kind of support arm lock of lifting machine.
Background technology
Lifting machine is a kind of equipment that is applied to automobile inspection, can, by vehicle lifting, vehicle bottom be overhauled.Because the vehicle dimension of Awaiting Overhaul varies in size, when using, lifting machine needs first support arm to be adjusted to after correct position, support arm is fixed, just can carry out the lifting of vehicle.The lifting machine using at present, the complex structure of support arm lock, welded and installed is all inconvenient, and need to manually unblank and locking, troublesome poeration, and to forget easily appear in manual operation, while making lifting machine work, support arm is in unlocked state, easily, in vehicle lifting process, there is the displacement of support arm, cause dropping of vehicle, cause the loss of property, even personnel's injures and deaths.
Utility model content
The utility model, for the problems referred to above, has designed a kind of support arm lock of new lifting machine.
Novel lifting machine support arm lock of the present utility model, be arranged in the lifting pedestal of lifting machine, one end of support arm is coupling in lifting pedestal, comprise the tooth piece that is provided with engaging tooth, tooth piece upper surface is provided with guiding adapter shaft, lower surface is provided with grounding connection axle, guiding adapter shaft and grounding connection axle are arranged on respectively in the axis hole of lifting pedestal top board and base plate setting, on guiding adapter shaft, retracing spring is installed, grounding connection shaft extension goes out lifting pedestal, tooth piece can be in lifting pedestal up-and-down movement, support arm the inner is provided with connecting panel, on connecting panel, be provided with multiple teeth groove that the engaging tooth of tooth piece is embedded.
Preferably, the axis hole that the cross-sectional plane of grounding connection axle and grounding connection axle are corresponding is all polygon.
The beneficial effects of the utility model are: novel lifting machine support arm lock, simple in structure, be easy to install, can be in the time that lifting pedestal lands automatic unlocking, coupler lock in the time that lifting pedestal rises, need not manual operation, easy to use, there will not be and forget, make lifting machine in vehicle lifting process, support arm locks, and avoids occurring the dropping of vehicle, property damage and personal casualty.
Accompanying drawing explanation
Accompanying drawing 1 is the constructional drawing of novel lifting machine support arm lock.
The specific embodiment
This novel lifting machine support arm lock, as shown in Figure 1, is arranged in the lifting pedestal 1 of lifting machine, and one end of support arm 2 is coupling in lifting pedestal 1.
Support arm lock comprises the tooth piece 3 that is provided with engaging tooth, tooth piece 3 upper surfaces are provided with guiding adapter shaft 4, lower surface is provided with grounding connection axle, guiding adapter shaft 4 and grounding connection axle are arranged on respectively in the axis hole of lifting pedestal 1 top board and base plate setting, on guiding adapter shaft 4, retracing spring 5 is installed, retracing spring 5 one end are against on the upper surface of tooth piece 3, and the other end is against on lifting pedestal 1 top board, and grounding connection shaft extension goes out lifting pedestal 1.
Tooth piece 3 can be at the interior up-and-down movement of lifting pedestal 1, and support arm 2 the inners are provided with connecting panel 6, is provided with multiple teeth groove that the engaging tooth of tooth piece 3 is embedded on connecting panel 6.
In the time that lifting pedestal 1 lands, grounding connection axle also contacts to earth, and ground upwards promotes grounding connection axle, and tooth piece 3 is lifted, and makes the teeth groove of engaging tooth disengaging support arm 2 connecting panels 6 of tooth piece 3, support arm 2 releases, and now retracing spring 5 is compressed.
After support arm 2 releases, with regard to the angle of capable of regulating support arm 2, make will lifting vehicle obtain good support.
After support arm 2 angular adjustment complete, lifting pedestal 1 rises, ground reduces gradually to the bearing force of ground connection adapter shaft, grounding connection axle also falls back to initial position gradually, in this process, compressed retracing spring 5 also presses down tooth piece 3, and tooth piece 3 is fallen back on the base plate in lifting pedestal 1 gradually, the engaging tooth of tooth piece 3 also falls in the teeth groove of connecting panel 6, and support arm 2 locks.
The axis hole that the cross-sectional plane of grounding connection axle and grounding connection axle are corresponding is all polygon, while avoiding 3 lifting of tooth piece, rotates.
