This U-shaped spring 1 and slide block 2 have the following disadvantages: U-shaped spring 1 and two slide blocks 2 are separate piece, and the motion of two slide blocks 2 need arrange guiding device 4, needs in the course of the work U-shaped spring 1 to coordinate and reach final braking action with two slide blocks 2.It easily produces cumulative error, assembly error, thereby the Security when affecting braking member overall precision and using, and braking member operation link in assembling, debug process is many, inefficiency, thereby increased manufacture cost, and because two slide blocks 2 are provided with guiding device 4, cause that arrestment mechanism is complicated, technique is loaded down with trivial details, manufacture cost is high.
Because above-mentioned defect, the design people, actively research and innovation in addition, to founding a kind of gradual elevator safety gear, makes it have more the value in industry.
Model utility content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of progressive type safety gear deformed spring of simple in structure, safe and reliable, low cost of manufacture.
Progressive type safety gear deformed spring of the present utility model, comprise the first planar surface portion, joint and boss, two ends, the left and right symmetry of described the first planar surface portion be bent downwardly and extend into two joints, the top of described joint is connected with the first planar surface portion, the end of described joint is all crooked and extend to form two boss to the inside, the top of described boss is connected with joint, and the base plane of described boss is inclined plane part, and the side of described boss is the second planar surface portion that is trapezoidal.
Concrete, described joint is two curved face part that also undergauge extends into that are bent downwardly by two ends, the left and right symmetry of the first planar surface portion.
Concrete, described joint is that be bent downwardly 90 ° and two of extending into by two ends, the left and right symmetry of the first planar surface portion face portion directly, and boss extends upward formation shoulder, and the top of described shoulder is connected with the end of facing portion directly.
Concrete, described the first planar surface portion, joint and the boss structure that is formed in one.
Concrete, in the first planar surface portion of described deformed spring, the second planar surface portion, be also provided with mounting hole.
By such scheme, the utility model at least has the following advantages: deformed spring is integrated into a part by a U-shaped spring and two slide blocks in existing catch block, simple in structure, not only reduced production and Installation and Debugging cost, also improved overall precision and the Security of these parts; One-body molded, there is stronger steadiness, be convenient to manufacture; Deformed spring is provided with mounting hole, is convenient to install.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and coordinate accompanying drawing to be described in detail as follows.
