Abstract
The invention provides a dowel pin which comprises a pin rod and a pin sheet. One end of the pin rod is provided with a limiting convex part, and the other end of the pin rod is provided with a U-shaped connecting opening. The middle of the pin sheet is provided with a long groove. The pin sheet is arranged in the U-shaped connecting opening, penetrates through a fixed shaft of the long groove, and is movably connected with the pin rod. The pin sheet is narrower than a mounting fixing hole, and the limiting convex part is wider than the mounting fixing hole. When the dowel pin is used, the pin sheet rotates around the fixed shaft for a certain angle so as to make the pin sheet radially parallel to the pin rod, and therefore, the combination structure of the pin sheet and the pin rod is plugged in the mounting fixing hole. When the dowel pin is used for fixing, the fixing can be finished as long as the pin sheet is adjusted to be horizontal. The dowel pin is convenient to disassemble and firm in fixing. The disassembly operation time can be obviously shortened, and the cost can be saved.
Description
Technical field
The present invention relates to a kind of steady pin, be mainly used in engineering, mechanical field.
Background technology
In existing field of engineering technology, in building field, generally fix between the steel form by the U-shaped card connection, can only under the situation that horizontal stupefied and roll is arranged, use, can only play adjacent forms and the tight effect of making, do not have fixing locked effect, and dismounting wastes time and energy, occasion such as more can't satisfy military affairs, speedily carry out rescue work.
Summary of the invention
The technical problem to be solved in the present invention is at the existing in prior technology defective, and a kind of steady pin of being convenient to dismounting, being connected firmly is provided.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
Steady pin comprises pin rod and pin sheet, the described pin rod one end system protuberance of limiting, and the described pin rod other end is established U type access port; Elongated slot is established at described pin sheet middle part; Described pin sheet is positioned at U type access port, and flexibly connects by fixed axis and the pin rod that runs through elongated slot.Pin sheet width is less than installing and fixing the hole, and the restriction protuberance is greater than installing and fixing the hole.During use, will sell sheet and rotate to an angle around fixed axis, and make the pin sheet radially and parallel, thereby the combining structure that will sell sheet, pin rod is filled in and installed and fixed the hole with pin rod; In the time of fixedly, will sell sheet and be adjusted into laterally, can finish fixing.
Further be improved to, an end of described elongated slot deflection pin sheet, the outer rim of this pin sheet end is a circular arc.Described pin sheet can be wedge shape, the small end of elongated slot deflection wedge shape, and this end outer rim is circular arc, can conveniently sell the rotation of sheet, the installation or removal that the opening of the pin sheet other end can conveniently be sold sheet.
Steady pin of the present invention can use under the situation of not having horizontal stupefied and roll, plays the effect of bearing vertical shearing power and lateral pull, the adjacent two punching block ribs of slab of pin hipocratic face, and easy accessibility can obviously shorten the dismounting operating time, and saves cost.

Accompanying drawing is used to provide further understanding of the present invention, and constitutes the part of manual, is used from explanation the present invention with embodiments of the invention one, is not construed as limiting the invention.In the accompanying drawings:
Fig. 1 is the structural representation of steady pin of the present invention;
Fig. 2 is the pin rod inner structure schematic diagram of steady pin of the present invention;
Fig. 3 is the pin rod side-looking structural representation of steady pin of the present invention;
Fig. 4 is the pin chip architecture schematic diagram of steady pin of the present invention;
Fig. 5 is the pin rod plan structure schematic diagram of steady pin of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the present invention, and be not used in qualification the present invention.
Shown in Fig. 1-5, steady pin comprises pin rod 1 and pin sheet 2, and pin rod 1 one ends are limited and made protuberance 11, and the pin rod other end is established U type access port 12; Pin sheet 2 is a wedge shape, thickness 4mm, and elongated slot 21 is established at the middle part, the small end of elongated slot 21 deflection wedge shapes, this end outer rim is circular arc; Pin sheet 2 is positioned at U type access port 12, and flexibly connects with pin rod 1 by the fixed axis 13 that runs through elongated slot 21.Pin sheet 2 width are less than installing and fixing the hole, and restriction protuberance 11 diameters are greater than installing and fixing the hole.
During use, will sell sheet 2 and rotate to an angle, and make pin sheet 2 radially and parallel, thereby the combining structure that will sell sheet 2, pin rod 1 is filled in and installed and fixed the hole with pin rod 1 around fixed axis 13; In the time of fixedly, will sell sheet 2 and be adjusted into laterally, can finish fixing.Product adopts the Q235 round steel, and the pin sheet is the drawing of 45# steel plate, turns blue after the heat treatment or zinc-plated processing.
Claims (3)
1. steady pin comprises pin rod and pin sheet, the described pin rod one end system protuberance of limiting, and it is characterized in that: the described pin rod other end is established U type access port; Elongated slot is established at described pin sheet middle part; Described pin sheet is positioned at U type access port, and flexibly connects by fixed axis and the pin rod that runs through elongated slot.
2. steady pin according to claim 1 is characterized in that: described elongated slot is partial to an end of pin sheet, and the outer rim of this pin sheet end is a circular arc.
