1. A square bar body; 10. a through hole; 11. a second inclined plane; 2. a fastener; 20. a nut; 21. a bolt head; 210. a first inclined plane; 211. a bump; 22. a screw; 3. a strip-shaped groove.
Detailed Description
Embodiments of the present invention are further described with reference to fig. 1 to 3.
The utility model discloses a door lock square bar convenient to installation, including square bar body 1 and fastener 2, be equipped with the through-hole 10 that runs through square bar body 1 both ends in the square bar body 1, fastener 2 includes nut 20, bolt head 21 and screw rod 22 that fuses with it, screw rod 22 anterior segment is equipped with the screw thread section, bolt head 21 is cylindrical setting, and the diameter of bolt head 21 reduces gradually towards the pole body of screw rod 22 and is formed with inclined plane first 210, screw rod 22 is located the through-hole 10 of square bar body 1, the through-hole 10 opening part that square bar body 1 is close to bolt head 21 one end is equipped with inclined plane second 11 that sets up with inclined plane first 210 in coordination, the both sides of the one end that square bar body 1 is close to bolt head 21 still set up the bar groove 3 that communicates with through-hole 10 be equipped with on the inclined plane first 210 of bolt head 21 and establish complex lug 211 with bar groove 3 card, the threaded section of the screw rod 22 extends out of the through hole 10, and the nut 20 is screwed on the threaded section of the screw rod 22 through thread matching and is abutted against the square bar body 1 to form fastening. And performing surface galvanizing treatment on the square strip body 1. The edges of the outer side surfaces of the square strip bodies 1 are arranged in a rounding mode.
Further, a cross or a straight groove is provided at the end of the bolt head 22. The cross or the straight groove is formed in the end part of the bolt head 21, so that the escape effect can be realized, namely the bolt head 21 is screwed by a screwdriver, the square strip body 1 is loosened and pulled back, and the effect of quickly opening the door and escaping is achieved.
The working principle is as follows: as shown in the first drawing, the screw 22 is fixed in the square bar body 1 through the clamping fit of the convex block 211 of the bolt head 21 and the square groove, and then the screw nut 20 is screwed, so that the screw 22 can drive the bolt head 21 to slide towards the square bar body 1, the first inclined plane 210 can extrude the second inclined plane 11 in the sliding process of the bolt head 21, and therefore the upper end of the square bar body 1 is deformed and unfolded through the strip-shaped groove 3 to fix the square bar body 1 in the lock cylinder, and the operation is very convenient and fast.
The utility model discloses a lock square has improved the installation effectiveness of square body 1, on the other hand can ensure the firm degree of square body 1 structure.
