Abstract

The utility model belongs to a safe ring for locks and buckles, comprising an opening suspension loop main body, a lock tongue, a lock sleeve, a helical compression spring and a card spring. One end of the lock tongue is hinged and connected with one opening end of the suspension loop main body. The end surface of the other end of the lock tongue is provided with a partial slope. The slope is connected and pressed on the corresponding slope of the other opening end of the suspension loop main body. The lock sleeve is sheathed on the connected and pressed position of the lock tongue and the suspension loop main body. The utility model is characterized in that the lock tongue is provided with a section of outer screw threads and the lock sleeve is provided with a section of inner screw threads which are matched with the lock tongue and are screwed on the lock tongue. The utility model has reliable locking.

Description

The snap close safety collar

The utility model belongs to the snap close safety collar.

The snap close safety collar is used for safety belt and is fixed on the connection at being connected of high-altitude part or safety belt two ends with other, to protect the safety of the person.Existing snap close safety collar is owing to adopt the movable lock tube that has groove spacing by the pin that passes groove, lock tube can not self-locking so can not safety locking, under the effect of external force, lock tube slip dead bolt is opened, safety belt is deviate from from the snap close safety collar, causes personal injury.

The purpose of this utility model provides a reliable snap close safety collar of locking.

The utility model is to establish internal thread at lock tube, does not have external screw thread at dead bolt, and lock tube utilizes screw thread friction self-locking, reaches the purpose of dead bolt positive lock.

The utility model is taked following structure, it comprises opening link main body, dead bolt, lock tube, spiral compression spring, card spring, the one end hinge joint of dead bolt is connected an openend of link main body, the end face of the other end of dead bolt has part to be the inclined-plane, this inclined-plane pressure is in the inclined surface of another openend of link main body when locking, and link main body and dead bolt are formed ring-type when locking; Spiral compression spring is installed in vertical hole of dead bolt, and the opening in this hole is in hinged end; There are two dops on the inclined-plane of the pressure end of link main body, and there is draw-in groove the pressure end both sides of dead bolt, and the inclined-plane pressure of dead bolt inclined-plane and link main body pressure end is together the time, and two dops are stuck in two draw-in grooves; The card spring becomes the obtuse angle, and an end of card spring is inserted in the inboard of spiral compression spring, and the other end of card spring withstands on the limiting stand of link main body hinged end; Lock tube is enclosed within dead bolt and can be enclosed within pressure place of dead bolt and link main body, it is characterized in that: at dead bolt one section external screw thread is arranged, have one section internal thread that matches with dead bolt to be screwed on the dead bolt at lock tube.

Because the utility model is taked said structure, change existing card slot type lock tube into the spiral lock tube, employing has the lock tube of internal thread and establishes external screw thread at dead bolt, just can utilize the screw thread friction that lock tube is tightened self-locking, dead bolt is reliably locked, have only with the stubborn lock tube of hand and just can open dead bolt,, avoid by the unreliable personal injury that causes of existing snap close safety collar so the utility model locking is reliable.

Detailed structure of the present utility model is provided by embodiment and accompanying drawing thereof.

Fig. 1 is the front view of the utility model embodiment.

Fig. 2 is the front view of the link main body of the utility model embodiment, and portion of pressure end office (EO) cuts open among the figure.

Fig. 3 is that this figure axially rotates along the profile of A-A line among Fig. 2.

Fig. 4 is the front view of dead bolt.

Fig. 5 is the vertical view of dead bolt.

Fig. 6 is the vertical view of card spring.

Fig. 7 is the front view of card spring.

Fig. 8 is the partial view of the utility model embodiment lock-out state, and lock tube is cut open among the figure, the hinged end partly cut-away of link main body and dead bolt.

Fig. 9 is the partial view of existing snap close safety collar lock-out state.

Among the above-mentioned figure:

1, link main body 2, bearing pin 3, dead bolt

4, card spring 5, spiral compression spring 6, lock tube

7, pin shaft hole 8, limiting stand 9, dop

10, inclined-plane 11, groove 12, draw-in groove

13, inclined-plane 14, dop 15, plug

16, vertical hole 17, draw-in groove 18, pin

Embodiment profile of the present utility model is seen Fig. 1, it comprises opening link main body 1, dead bolt 3, lock tube 6, one end of dead bolt 3 is connected an openend of link main body 1 with bearing pin 2 hinge joints, another openend pressure of the other end of dead bolt 3 and link main body 1 together, lock tube 6 is enclosed within dead bolt 3 and can moves axially along dead bolt 3 and is enclosed within dead bolt 3 and link master pressure place.

The outline drawing of link main body 1 is seen Fig. 2, Fig. 3, at the pressure end of link main body 1 inclined-plane 10 is arranged, and this inclined-plane has and forms groove 11 between two dops, 9, two dops 9, and the both sides of groove 11 tilt.

The profile of dead bolt 3 is seen Fig. 4, Fig. 5, has part to be inclined-plane 13 at the pressure end of dead bolt 3, and inclined-plane 13 is corresponding with inclined-plane 10, and two draw-in grooves 12 are arranged in pressure end both sides, the 13 part both sides formation dop 14 on the inclined-plane.

The profile of card spring 4 is seen Fig. 6, Fig. 7, and its end is a plug 15, and the other end is a flake main body, and plug 15 becomes the obtuse angle with flake main body.

The dead bolt 3 of the utility model lock-out state is seen Fig. 8 with the annexation of lock tube 6 and link main body 1, and inclined-plane 13 pressures of dead bolt 3 are stuck in the draw-in groove 12 of dead bolt 3 at 10, two dops 9 in the inclined-plane of link main body 1 correspondence; Spiral compression spring 5 is installed in vertical hole 16 of dead bolt 3, the opening in this hole is in hinged end, the plug 15 of card spring 4 is inserted in the inboard of spiral compression spring 5, the other end of card spring 4 withstands on the limiting stand 8 of link main body 1 hinged end, it is characterized in that: at dead bolt 3 one section external screw thread is arranged, have one section internal thread that matches with dead bolt 3 to be screwed on the dead bolt 3 at lock tube.

Existing snap close safety collar dead bolt 3 is seen Fig. 9 with the locking of link main body, it be by pin 18 in groove card 17 lockings of lock tube 6, draw-in groove 17 is the mountain font in the part of dead bolt 3, is in-line at the pressure end of link main body 1, clearly, lock tube 6 slides easily.
