The sidewall of the roller is provided with evenly distributed diamond-shaped knurled patterns. One end of the roller is inserted into the insertion hole and extends into the slot. A disadvantage of this utility model is that the anti-theft method of the bolt is only for anti-theft when connected to a nut, which limits its scope of application. Utility Model Content

[0004] The utility model aims to overcome the deficiency of the prior art that most of the connection modes are used for anti-theft, and provides a latch-type hot-dip galvanized anti-theft bolt which is adapted to different connection modes through multiple anti-theft modes.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A latch-type hot-dip galvanized anti-theft bolt comprises a screw, a nut, a latch assembly, a nut and a fixing frame. One end of the screw is detachably connected to the nut. A socket is provided on the end surface of the screw connected to the nut. The latch assembly is installed in the socket. The nut is threadedly connected to the screw. The fixing frame is installed at the other end of the screw and connected to the nut.

[0007] The screw is the connecting body used to fix parts. A nut is installed at the upper end of the screw. The existence of the nut makes it easy to screw the screw for fixing. A pin assembly is installed at the upper end of the screw. When the screw is connected to the threaded hole, the pin assembly fixes the screw in the threaded hole through the pin assembly to achieve the purpose of anti-theft. When the screw is connected to the nut, the nut is fixed to the screw through the fixing frame and cannot be rotated to prevent theft. In this way, two different connection methods can be applied, achieving the purpose of adapting to different connection methods through multiple anti-theft methods.

[0008] Preferably, a baffle is mounted on the upper end of the screw, and the baffle is provided with a plurality of connecting holes distributed in a circumferential manner. A plurality of connecting rods are mounted on one side of the nut, and the connecting rods correspond to the connecting holes one by one. The nut is detachably connected to the baffle through the engagement of the connecting rods and the connecting holes. The baffle is mounted on the upper end of the screw for fixing parts. When the baffle is cylindrical, it is rotated without applying external force, thereby mounting the nut on the baffle. The nut is connected by inserting the connecting rod into the connecting hole of the baffle. When the screw is screwed, the nut is mounted on the baffle for screwing. After the installation is completed, the nut is removed to ensure that the screw is not easily screwed, thereby performing preliminary anti-theft measures. Such a design allows the nut to be removed.

During the process of inserting the latch into the socket, the protruding rod is gradually squeezed outward, and the side of the latch fits with the fitting plate on the protruding rod, squeezing the other end of the protruding rod out of the screw. A pointed cone is installed at the end of the protruding rod that protrudes from the screw. The pointed cone squeezes the inner wall of the threaded hole during the process of the protruding rod protruding from the screw, thereby completely fixing the screw in the threaded hole, thereby achieving an anti-theft effect. Such a design can fix the screw.

[0010] Preferably, a plurality of evenly distributed snap rings are mounted on the inner wall of the socket, each having a triangular cross-section. The latch pin is provided with a plurality of slots, each snap ring corresponding to each slot. During insertion of the latch pin into the socket, the slots on the latch pin correspond one-to-one with the snap rings on the inner wall of the socket, securing the latch pin within the socket. The triangular cross-section of the snap rings ensures smooth insertion of the latch pin and prevents the snap rings from being easily removed, thereby ensuring that the latch pin is always positioned within the socket to support the extension rod. This design can secure the latch pin.

[0011] Preferably, the fixing frame includes a mounting plate and a fixing rod, wherein both sides of the nut are provided with a fixing groove 1, the cross-sectional shape of the fixing groove 1 being semicircular, and both sides of the screw are provided with a fixing groove 2, the cross-sectional shape of the fixing groove 2 being semicircular, and the fixing groove 1 matches the fixing groove 2, the mounting plate is placed at the lower end of the screw, and fixing rods are installed on both sides of the mounting plate, and the fixing rods are placed in the fixing groove 2, and one side of the fixing rod matches the fixing groove 1. When the screw and the nut are matched, the nut is fixed by the fixing frame, and the fixing grooves 1 opened on both sides of the screw can respectively match the fixing grooves 1 opened on both sides of the inner wall of the nut to form a complete circular hole, the mounting plate of the fixing frame is placed on the bottom surface of the screw, and the fixing rod installed on the mounting plate is placed in the fixing groove 2, and one side of the upper end of the fixing rod is placed in the fixing groove 1, and the fixing rod is placed in the circular hole formed by the fixing groove 1 and the fixing groove 2 to ensure the relative position of the nut and the screw, and after the fixing rod is inserted, it is ensured that the nut cannot rotate on the screw, thereby achieving an anti-theft effect, and such a design can fix the nut.

[0012] Preferably, the end face of the screw is provided with a snap-in groove, the snap-in groove corresponding to the mounting plate, the mounting plate placed in the snap-in groove and abutting against the bottom surface of the snap-in groove, a plurality of snap-in blocks distributed circumferentially mounted on the inner wall of the snap-in groove, the bottom surfaces of the snap-in blocks contacting the mounting plate.
