Abstract
The utility model discloses a kind of gate-type lifting machine trailing arm, comprise front trailing arm and rear trailing arm, one end of front trailing arm is inserted in one end of rear trailing arm, and both form scalable connection, the other end of described front trailing arm is provided with supporting seat mounting hole and supporting seat, and supporting seat bottom centre is provided with screw rod; In described supporting seat mounting hole, screw thread is provided with and increases cover in hollow tubular, and increase the degree of depth of height higher than supporting seat mounting hole of cover, increase in the inwall of cover and offer negative thread, described screw flight revolves to be located to be increased in cover.The utility model, by all adopting the design of increasing cover of thread connecting mode inside and outside utilization, improves the height stroke range of supporting seat, and is convenient to detachable maintaining, improve working strength.
Description
Technical field
The utility model belongs to lifting machine manufacturing technology field, is specifically related to a kind of gate-type lifting machine trailing arm.
Background technology
Auto hoist is the equipment for lifting automobile in vehicle maintenance and repair process, and automobile reaches lifting machine station, vehicle hoisting can be made to arrive certain height, be convenient to vehicle maintenance and repair by manual operation.Gate-type lifting machine, as the important kind of in auto hoist, plays very important effect in vehicle maintenance and repair.
The trailing arm of gate-type lifting machine adopts two sectional type structure mostly, comprises front trailing arm and rear trailing arm, and one end of front trailing arm is inserted in rear trailing arm, and other end top is provided with the supporting disk perpendicular with it.In the prior art, supporting disk revolves the arm end place being located at front trailing arm usually by the screw rod be arranged on bottom it, its weak point is, supporting disk stroke height setting range is little, and working strength is not high yet.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and provide a kind of convenient for production, low cost of manufacture, working strength is high, the gate-type lifting machine trailing arm that supporting disk stroke height setting range is large.
A kind of gate-type lifting machine trailing arm, comprise front trailing arm and rear trailing arm, one end of front trailing arm is inserted in one end of rear trailing arm, and both form scalable connection, the other end of described front trailing arm is provided with supporting seat mounting hole and supporting seat, and supporting seat bottom centre is provided with screw rod; In described supporting seat mounting hole, screw thread is provided with and increases cover in hollow tubular, and increase the degree of depth of height higher than supporting seat mounting hole of cover, increase in the inwall of cover and offer negative thread, described screw flight revolves to be located to be increased in cover.
The lateral wall of described rear trailing arm is provided with nigger, and the two ends of nigger are all arranged on by bolt on the lateral wall at rear trailing arm two ends.
The utility model, by all adopting the design of increasing cover of thread connecting mode inside and outside utilization, improves the height stroke range of supporting seat, and is convenient to detachable maintaining, improve working strength.
Additionally by rear trailing arm, nigger is installed, improves the degree of convenience during workman's push-and-pull operation.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is plan structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described further.Should be understood that following examples only for illustration of the utility model but not for limiting scope of the present utility model.
See Fig. 1 and Fig. 2, a kind of gate-type lifting machine trailing arm that the utility model provides, comprise front trailing arm 1 and rear trailing arm 2, one end of front trailing arm 1 is inserted in one end of rear trailing arm 2, and both form scalable connection, the other end of front trailing arm 1 is provided with supporting seat mounting hole 3, supporting seat 4 bottom centre is provided with screw rod 5, in the prior art, supporting seat 3 is all inserted by screw rod 5 and is installed in the supporting seat mounting hole 3 of front trailing arm 1, in order to solve the technical matters described in background technology, the technical solution of the utility model is, in supporting seat mounting hole 3, screw thread is provided with and increases cover 6 in hollow tubular, increase the degree of depth of height higher than supporting seat mounting hole 3 of cover 6, increase in the inwall of cover 6 and offer negative thread, screw rod 5 screw thread revolves to be located to be increased in cover 6, in order to ensure that increasing cover 6 installs tautness at supporting seat mounting hole 3, if do not adopt screw thread to install, also welding can be adopted, the mounting meanss such as interference fit, but for the ease of detachable maintaining, screw thread mounting means is adopted to be best, the height increasing cover 6 also can be increased according to service condition, the stroke of screw rod 5 is strengthened.
Embodiment 1, in order to improve the utility model comfort level in use, is convenient to artificial push-and-pull, can install nigger 7 as shown in Figure 2 on the lateral wall of rear trailing arm 2, and the two ends of nigger 7 are all arranged on by bolt 8 on the lateral wall at rear trailing arm 2 two ends.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
