Abstract
The invention discloses a novel scissor jack which comprises a jack head, a base, a pair of upper supports and a pair of lower supports, wherein one end of each upper support is mounted on the jack head, the other end of each is connected with one end of the lower support, and the other end of each lower support is mounted on the base, and the end parts of the upper supports mounted on the jack head are shaped like teeth, and the pair of the upper supports are mutually meshed; the end parts of the pair of the lower supports mounted on the base are mutually independent; and the tooth-shaped end parts on the lower supports of the scissor jack are eliminated, the end parts of the lower supports are kept to be mutually independent and can move, and the working state of the jack is kept stable, thereby keeping a jacked object stable and improving the safety of the use of the scissor jack. On the other hand, as the lower supports do not have the tooth-shaped end parts, the cost is saved when opening a mold and the processing cost is saved when processing.
Description
Technical field
The present invention relates to a kind of lifting gear jack, particularly a kind of novel scissor jack.
Background technology
At present, the important hoisting device that market is widely used in autotruck or mobile device upper support equipment self-weight, adjust equipment level is a scissors-type jack, and it is by top or bottom jacking weight in little stroke.In the application process of scissors-type jack, the user often finds, when by the object overbalance of jacking, because a pair of lower bracket of scissors-type jack is meshing mutually by the gear on the support, keep balance between the lower bracket, will make the single-piece overbalance of scissors-type jack like this, cause the instability of the scissors-type jack under the mode of operation, potential safety hazard occur.
For example, when the automobile that jacking is being exitted, because the speed difference of each wheel venting of automobile, will cause the overbalance of automobile, the feasible force unbalance that is applied on the scissors-type jack, and the support of scissors-type jack still keeps relative balance at this moment, when unbalanced power differs too big, can cause the scissors-type jack instability under the mode of operation.
Summary of the invention
Technical matters to be solved by this invention provides a kind of novel scissor jack of stable working state.
For solving the problems of the technologies described above technical scheme of the present invention be: a kind of novel scissor jack, comprise top, base, a pair of upper bracket, a pair of lower bracket, one end of upper bracket is installed on the top, its other end connects an end of lower bracket, the other end of lower bracket is installed on the base, the end that is installed in the upper bracket on the top is set to dentation, and a pair of upper bracket is meshing mutually; The end that is installed in a pair of lower bracket on the base is separate.
In application process, when by the object overbalance of jacking, because a pair of upper bracket of scissors-type jack is meshing mutually by support upper end dentation, and relative static between top and the object, the power that has kept jacking in vertical direction; And the lower bracket end between keep relatively independent, can be movable, make the overbalance of object be converted into the overbalance of lower bracket to base, make the base of scissors-type jack keep balance, stable thereby the mode of operation of scissors-type jack has kept.
The invention has the beneficial effects as follows: the dentation on the scissors-type jack lower bracket is eliminated, keep relatively independent between the lower bracket end, can be movable, it is stable that the mode of operation of jack has kept, make by the object of jacking to keep stable, improved the safety that scissors-type jack uses.On the other hand, lower bracket of the present invention has not had dentation, has saved cost when die sinking, has saved cost of processing when processing.
Description of drawings
Fig. 1 is the structural representation of scissors-type jack;
Fig. 2 is the structural representation that the support of dentation is arranged;
Fig. 3 is the structural representation that does not have the support of dentation.
The specific embodiment
The present invention will be further described in detail below in conjunction with specific embodiment.
As shown in Figure 1, a kind of novel scissor jack comprises top 1, base 2, a pair of upper bracket 3, a pair of lower bracket 4, and an end of upper bracket 3 is installed on the top 1, and its other end connects an end of lower bracket 4, and the other end of lower bracket 4 is installed on the base 2.
As shown in Figure 2, the end that is installed in the upper bracket 3 on the top 1 is set to dentation 5, and when being installed on the top 1, a pair of upper bracket 3 is meshing mutually; As shown in Figure 3, the end that is installed in a pair of lower bracket 4 on the base has not had dentation 5, and a pair of lower bracket 4 is separate when being installed on the base 2.
When by the object overbalance of jacking, a pair of upper bracket 3 of the present invention is meshing mutually by support upper end dentation 5, and come directly towards 1 with object between relative static, the power that has kept jacking is in vertical direction; And lower bracket 4 ends between keep relatively independent, can be movable, make the overbalance of object be converted into the overbalance of 4 pairs of bases 2 of lower bracket, make the base of scissors-type jack keep balance, stable thereby the mode of operation of scissors-type jack has kept.
The foregoing description does not limit the present invention in any way, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in protection scope of the present invention.
