Detailed Description

Embodiments of the present utility model will be further described with reference to fig. 1 to 3.

The utility model discloses a novel door lock square bar, which comprises two square bars 1 which are symmetrically arranged, wherein the two square bars 1 are mutually buckled to form a square bar body 2 for fixedly connecting a handle 6, the square bar body 2 is of a square structure, the center positions of the two square bars 1 are respectively bent towards the outer side to form a clearance cavity 3, clamping grooves 10 are respectively arranged on one sides, away from each other, of the two ends of the two square bars 1, clamping blocks 11 are uniformly arranged in the clamping grooves 10 from top to bottom, inclined grooves 12 are respectively arranged on the side walls, spliced with each other, of the two ends of the two square bars 1, and inclined grooves 12 at the two ends of the two square bars 1 are mutually spliced to form inclined guide gaps 4 for inserting a jacking device 7.

Further, in order to realize convenient installation of the two square strips 1, two ends of one square strip 1 of the two square strips 1 are respectively provided with a positioning block 13, and two ends of the other square strip 1 are respectively provided with a positioning groove 14 which is clamped and matched with the positioning block 13. Through the cooperation of establishing of the card of locating piece 13 and constant head tank 14 for people can form a whole when installing two square strips 1, be convenient for people to wear two square strips 1 and establish the lock body to and the card is established on handle 6.

Further, the two ends of the square strip body 2 are respectively provided with an arc chamfer 20 which is convenient for connecting the handle 6.

The utility model discloses a square strip body 2 is when the installation, is formed with clearance chamber 3 through being directed towards outside bending respectively at the central point of two square strips 1 for interference fit can be realized when two square strips 1 are fixed in the lock body is inside, and two square strips 1 produce elastic pressure between assembly back surface and the lock body, thereby obtain the installation of fastening. When two square strips 1 are installed in handle 6, the tight jacking device 7 can insert through handle 6 and establish the slope guiding notch 4 department of two square strips 1, when tight jacking device 7 inserts and establishes in the slope guiding notch 4, tight jacking device 7 can strut two square strips 1 in handle 6 for more inseparable cooperation between two square strips 1 and handle 6 is fixed, and the fixture block 11 that two square strip body 2 both sides set up simultaneously also can be tightly block establish in handle 6, realizes further fixed.

The utility model discloses a square strip 1 of concatenation formula for tight device 7 in top can be more stable fix square strip body 2 in handle 6, be difficult for not hard up in long-time use, its structure is more stable, is worth powerful popularization.
