Furthermore, the bolt seat is plate-shaped, and the axis direction of the positioning plate is perpendicular to the axis direction of the bolt seat.

Description of the drawings:

fig. 1 is a schematic structural diagram of the present invention.

The specific implementation mode is as follows:

the invention will be further explained with reference to the drawings and the detailed description below:

as shown in figure 1, a bidirectional door bolt comprises a connecting seat 1, a bolt seat 2 and a movable pin 3, wherein the movable pin 3 is slidably arranged on the bolt seat 2, an iron plate is welded on the upper surface of the connecting seat 1, the iron plate protrudes upwards to form a plug hole with the connecting seat, the front end of the movable pin 3 is used for being plugged in or being separated from the connecting seat, at least two square fixing holes 6 are respectively arranged on the connecting seat 1 and the bolt seat 2, wherein, two round holes and two square fixing holes 6 are arranged on the connecting seat 1, the connecting seat 1 is a square plate, the round holes and the square fixing holes 6 are arranged at the corners of the connecting seat in a diagonal manner, the bolt seat 2 is also in a plate structure, an upper square fixing hole and a lower square fixing hole 6 are arranged at the middle part of the bolt seat 2, the round fixing holes or the square fixing holes can be selected as the corners of the bolt seat 3, the connecting seat and the bolt seat are, meanwhile, a screw is arranged in the circular hole in a penetrating mode to be fixed together. The welding has locating plate 21 on bolt seat 2, the topside in the middle of locating plate 21 has breach 210 and makes the locating plate topside of breach both sides form two independent spacing units 211, breach 210 bottom surface is the arc surface, be equipped with a through-hole 212 on the locating plate of breach 210 below, still be equipped with two lockholes 213 on locating plate 21, two lockholes 213 are located this through-hole 212 both sides respectively and are higher than the setting of breach bottom surface, the one end welding that connecting seat was kept away from to locating plate 21 has limiting plate 22 that can block the loose pin, spacing that limiting plate 22 apart from the locating plate uses the loose pin can throw off the connecting seat as the standard, of course, also can set for standard interval, set up the linear distance of connecting seat and bolt seat. The one end that locating plate 21 is close to the connecting seat has the protruding locating hole that forms that makes progress, the shaping of locating hole can be formed through the iron plate of a welding on the bolt seat is protruding upwards, the activity round pin 3 is worn to locate in this locating hole and this through-hole and can rotate around self axial, the vertical welding has locating pin 4 on the activity round pin 3, 4 one ends of locating pin are fixed with activity round pin 3, 4 other ends of locating pin are buckled and are formed with bayonet 5 towards the activity round pin direction, this bayonet 5 can block in spacing unit 211, when the bayonet block in spacing unit, 3 front ends of activity round pin and the spliced eye of connecting seat are inserted and are closed, then fix this locating pin on the locating plate through the lockhole, make whole bolt be in locking state.

Preferably, the top edge of the limiting unit is a circular arc edge bent downwards. In addition, in order to smoothly push the movable pin when the movable pin slides, the distance from the end part of the bent end of the positioning pin to the pin base is larger than the distance from the bottom surface of the notch to the pin base. And for convenient assembly and better cooperation, the width of the positioning plate is consistent with that of the bolt seat, the bolt seat is plate-shaped, and the axis direction of the positioning plate is vertical to the axis direction of the bolt seat.

The utility model discloses a set up two at least square fixed orificess to fix through the carriage bolt, make connecting seat and removable pin can't dismantle from door body one side, improve the security performance, and the locating plate both sides form two independent spacing units, through the cooperation with locating pin bayonet socket and lockhole, can avoid the bolt to throw off the connecting seat, improve the security. This compact structure, and the removable pin is solid pole usually, through setting up the limiting plate and not the deflector structure that can run through for holistic cost is lower. In addition, because both ends all have spacing unit on the locating plate, like this, to two opening the door, no matter which door the connecting seat is installed on, all can be corresponding to installation bolt seat on another door, compare in the specific installation of prior art, obviously make things convenient for a lot of.

The foregoing is illustrative of the preferred embodiments of the present invention only, and is not to be construed as limiting the claims. All the equivalent structures or equivalent flow changes made by using the contents of the specification and the attached drawings of the utility model are included in the patent protection scope of the utility model.
