Abstract
一种齿条直线升降式汽车用千斤顶，包括：由固定齿条、后盖板、下盖板、左右固定板构成的长盒状壳体，固定齿条的外侧设有轴向矩形凹槽，中部设有通孔，紧靠在升降齿条一侧的导向滑块，设置在盒状壳体与导向滑块之间的回位弹簧，固定在盒状壳体凹槽处的杠杆。升降齿条和固定齿条相互啮合以承担重量，升降齿条的升降运动通过杠杆的动作完成。在固定齿条上开有轴向矩形槽，工作完成后可将手柄杠杆回收于轴向矩形凹槽内。本实用新型的汽车用千斤顶采用齿条啮合传动形式和杠杆运动巧妙结合，结构简单、使用方便、省力、效率较高，并且便于携带存放，为一种具有较大实用价值的可折叠千斤顶。
A rack linear lifting jack for automobiles, comprising: a long box-shaped housing composed of a fixed rack, a rear cover, a lower cover, and left and right fixing plates, and an axial rectangular groove is arranged on the outer side of the fixed rack. The middle part is provided with a through hole, which is close to the guide slider on one side of the lifting rack, the return spring arranged between the box-shaped housing and the guide slider, and the lever fixed at the groove of the box-shaped housing. The lifting rack and the fixed rack are engaged with each other to bear the weight, and the lifting movement of the lifting rack is completed by the action of the lever. There is an axial rectangular groove on the fixed rack, and the handle lever can be recovered in the axial rectangular groove after the work is completed. The automobile jack of the utility model adopts the ingenious combination of rack meshing transmission form and lever movement, has simple structure, convenient use, labor saving, high efficiency, and is easy to carry and store. It is a foldable jack with great practical value.
Description
Technical field
The utility model relates to a kind of automobile inspection jack, specifically, relates to a kind of by engagement of tooth bar vertical direction and the combined jack of tiller.
Background technology
Jack is the requisite a kind of lifting tool of automobile inspection.Normally used automobile has fluid pressure type, mechanism's formula and spiral with jack.No matter the jack of these several patterns reaches best far away at the aspects such as comfort feature alerting ability of reasonableness, appearance and modeling and the use of the combination of the reasonableness of structure, type of belt drive, intensity distributions.
Summary of the invention
The utility model technical issues that need to address provide a kind of rack linear lifting type automobile jack, the utility model is tooth bar engaged transmission form and the ingenious combination of lever motion, simple in structure, easy to use, laborsaving, efficient is higher, be easy to carry deposit, collapsible jack handsome in appearance.
The technical solution of the utility model:
Jack of the present utility model comprises:
A long box shape housing that constitutes by stationary rack, back shroud, lower cover, left and right sides adapter plate, the outside of stationary rack is provided with axial rectangular recess, and the middle part is provided with through hole;
One is arranged on the lifter rack that is meshed with stationary rack in the box-like housing;
A guide runner that abuts against lifter rack one side;
A plurality of pull back springs that are arranged between box-like housing back shroud and the guide runner;
A lever that is fixed on the stationary rack groove, the one end inserts the through hole on the stationary rack, and offsets with lifter rack.
The profile of tooth of lifter rack and stationary rack adopts zigzag structure, both are meshing with each other at work to bear weight, the dipping and heaving of lifter rack is finished by the action of lever, in use, the handle with lever lifts earlier, and the part that allows the other end have wedge angle is meshed with the tooth of lifter rack, then handle one end of lever is depressed, just can make tooth position of lifter rack rising, so perseveration just can realize promoting the effect of weight.The reversing sense action of lever just can realize the descending motion of lifter rack.
Owing on stationary rack, have an axial rectangular channel, after finishing, work tiller can be recovered in the groove, because the length of whole lever handle equates with the height of jack, make whole jack compact appearance, be an outward appearance hexahedron structure.
As seen from the above technical solutions, automobile of the present utility model adopts tooth bar engaged transmission form and the ingenious combination of lever motion with jack, simple in structure, easy to use, laborsaving, efficient is higher, and be easy to carry and deposit, be a kind of collapsible jack with big practical value.
Description of drawings.
Fig. 1 is a main structure scheme drawing of the present utility model.
Fig. 2 is an A-A cutaway view of the present utility model.
The specific embodiment
Referring to Fig. 1 and Fig. 2, the rack linear lifting type automobile jack that the utility model is alleged comprises:
A long box shape housing that constitutes by stationary rack 1, back shroud 81, lower cover 82, left and right sides adapter plate 83, the outside of stationary rack 1 is provided with axial rectangular recess 6, and the middle part is provided with through hole 11;
One is arranged on the lifter rack 2 that is meshed with stationary rack 1 in the box-like housing;
A guide runner 4 that abuts against lifter rack 1 one sides;
A plurality of pull back springs 5 that are arranged between box-like housing back shroud 81 and the guide runner 4;
A lever 3 that is fixed on stationary rack 1 groove 6 by bearing pin 9, the one end inserts the through hole 11 on the stationary rack 1, and offset with lifter rack 2, lever 3 is an axial long hole with the mating holes 10 of lever bearing pin 9, can make lever about 3 movable, thereby not influence the engagement of lifter rack 2 and bearing stationary rack 1;
For reducing the resistance in lifter rack 2 lifting process, be provided with plurality of balls 7 between guide runner 4 and the lifter rack 2, realizing rolling cooperates.
