Abstract
The utility model discloses a mechanical locking mechanism for a support arm of a two-column car lift. An intermediate component of the support arm adopts a structure of an upper U-shaped groove and a lower U-shaped groove which are staggered. The mechanism is characterized in that mechanical limiting devices are mounted on both sides of the intermediate component of the support arm. The mechanical limiting devices of the support arm are mounted on both sides of the intermediate component to greatly reduce the space above or below components of the support arm, thereby avoiding the drooping of the support arm during use, and ensuring the use safety of the two-column car lift.
Description
Technical field
The utility model relates to a kind of lifting machine, relates to an arm mechanism of double-column lifter specifically.
Background technology
Automobile two post lifting machine support arms adopt the overhead type mechanical lock mechanism to guarantee that the relative position between the arm part not at the same level locks more.Mechanism's lockout mechanism of overhead type need take limited space in a large amount of support arms, simultaneously because support arm is central because the top exists the shared space of mechanical lock mechanism can produce sagging phenomenon in use, thereby influences the safe in utilization of two post auto hoists.
Summary of the invention
At the deficiency of prior art, the utility model provides a kind of support arm mechanical lock mechanism of automobile two post lifting machines.
Below introduce the utility model in detail, a kind of support arm mechanical lock mechanism of automobile two post lifting machines; The centre part of described support arm is the U type groove structure that staggers up and down; The both sides of described support arm centre part all are provided with mechanical stop limiter.
Optimize, described mechanical stop limiter is the mechanical position limitation piece that is installed in support arm centre part both sides.
Optimize, the last U type groove of described support arm centre part cooperates with the interior pipe of support arm, and U type groove cooperates with the outer tube of support arm under it.
The utility model has the advantages that: the support arm mechanical stop limiter is installed in the both sides of centre part, thereby make the space of each parts top of support arm or below to reduce greatly, thereby avoided the sagging that in the middle of use, produces, guaranteed the safe in utilization of two post auto hoists.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is the structural representation of the utility model support arm centre part.
The specific embodiment
Below in conjunction with Figure of description the present invention is done further disclosure.
See also accompanying drawing 1 and accompanying drawing 2, a kind of support arm mechanical lock mechanism of automobile two post lifting machines; The centre part 2 of described support arm 1 is the U type groove structure that staggers up and down; The last U type groove 3 of support arm centre part 2 cooperates with the interior pipe 4 of support arm, and U type groove 5 cooperates with the outer tube 6 of support arm under it.
The both sides of support arm centre part 2 all are provided with mechanical stop limiter, and this mechanical stop limiter is the mechanical position limitation piece 7 that is installed in support arm centre part both sides.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
