In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a safety tongs is with fixed brake block, includes fixed bottom block and upside lug, the installation of upside lug is fixed on the upper end intermediate position of fixed bottom block, the upper end inboard of upside lug is provided with the upside through-hole, the lower extreme inboard of upside lug is provided with the downside through-hole, the outside week side of upside lug is provided with the rhombus groove.

Preferably, the fixed bottom block and the upper side lug are formed by turning, and the outer sides of the fixed bottom block and the upper side lug are in the same straight line.

Preferably, the inner through holes of the upper through hole and the lower through hole are equal in size, and the upper through hole and the lower through hole are symmetrically fixed on the upper bump.

Preferably, the fixed bottom block and the upper side lug are in a step shape, and the outer sides of the fixed bottom block and the upper side lug are L-shaped grooves.

Preferably, the surface of the upper side bump is painted with rust preventive oil.

Compared with the prior art, the beneficial effects of the utility model are that:

the step that safety tongs constituted through fixed bottom block and upside lug with fixed brake block for with the fixed distance that need not readjustment between the pincers body inner wall, and the upside lug passes through the rhombus groove in the outside, when can increase the braking of safety tongs like this, the coefficient of friction of brake block and elevator T type guide rail, thereby make the better braking of safety tongs, the rhombus groove can make iron fillings and fatlute that brake block and T type guide rail friction planing got off discharge more easily, reduce iron fillings, the influence of fatlute when braking to safety tongs.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides an embodiment: a fixed brake block for safety tongs comprises a fixed bottom block 1 and an upper side lug 2, wherein the upper side lug 2 is installed and fixed at the middle position of the upper end of the fixed bottom block 1, an upper side through hole 3 is formed in the inner side of the upper end of the upper side lug 2, a lower side through hole 5 is formed in the inner side of the lower end of the upper side lug 2, and a diamond groove 4 is formed in the outer periphery side of the upper side lug 2;

the fixed bottom block 1 and the upper side lug 2 are in a step shape, the outer sides of the fixed bottom block 1 and the upper side lug 2 are in an L-shaped groove, the fixed bottom block 1 and the upper side lug 2 are formed by turning, the outer sides of the fixed bottom block 1 and the upper side lug 2 are positioned on the same straight line, the inner through holes of the upper side through hole 3 and the lower side through hole 5 are equal in size, the upper side through hole 3 and the lower side through hole 5 are symmetrically fixed on the upper side lug 2, and the surface of the upper side lug 2 is coated with anti-rust oil;

specifically, as shown in fig. 1, fig. 2, fig. 3, fig. 4 and fig. 5, when the mechanism is used, firstly, the step shape is formed by the outer shape of the fixed bottom block 1 and the upper side lug 2, and the outer sides of the fixed bottom block 1 and the upper side lug 2 are in the L-shaped groove, so that the distance between the fixed bottom block 1 and the inner wall of the caliper body is fixed without readjustment, and when the mechanism is fixed, the fixed bottom block 1 and the upper side lug 2 pass through the upper side through hole 3 and the lower side through hole 5 on the inner side, so that the fixing by the screw is convenient, the installation, fixation and use are convenient, so that the fixed bottom block 1 and the upper side lug 2 are not easy to loosen and fall off when in use, and the fixed bottom block 1 and the upper side lug 2 of the fixed bottom block 1 and the upper side lug 2 are formed by turning, so that the joint of the fixed bottom block 1 and, and during the use, upside lug 2 passes through rhombus groove 4 in the outside, so can increase the safety tongs braking time, thereby the coefficient of friction of brake block and elevator T type guide rail makes the better braking of safety tongs, and rhombus groove 4 can make iron fillings and fatlute that brake block and T type guide rail friction planing got off discharge more easily, reduces iron fillings, fatlute influence when the braking of safety tongs.

The working principle is as follows: the utility model discloses when using, fixed bottom block 1 and upside lug 2 are through inboard upside through-hole 3 and downside through-hole 5, effective set screw like this to be convenient for install and fix and use on the assigned position. When the anti-rust oil is used, the outer sides of the fixed bottom block 1 and the upper side convex block 2 are coated with the anti-rust oil, so that the anti-rust oil is not easy to rust and damage, and the service life of the whole body is effectively prolonged. During supporting, the fixed bottom block 1 and the upper side convex block 2 are formed through turning, so that the joint of the fixed bottom block 1 and the upper side convex block 2 is not easy to break and damage.
