Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a hook connection locking structure. Background Art

[0002] At present, the hook locking structure used in most tractors on the market is a pull-and-fix type, which usually includes a hook seat, a locking pin, and a fixing rope. When the height of the hook and the hook locking structure are the same, the personnel need to get off the vehicle and pull the locking end switch to raise the locking pin with the fixing rope. Then the personnel manually pull the vehicle forward to the fixed position, loosen the lifting fixing rope, and the locking pin can be inserted into the hook seat to complete the locking. This process requires the employee to get off the vehicle and manually pull the locking switch rope, and the personnel need to squat and pull the vehicle in the direction of the vehicle with one hand to fix it, which wastes working hours and is not convenient to operate. Therefore, it is necessary to design a new hook connection locking structure. Utility Model Content

[0018] like Figures 1 to 5 A hook connection locking structure shown in the figure comprises a hook seat 1 of a U-shaped structure, openings are provided on the left and right sides of the hook seat 1 and on the side facing the traction frame 10, hook grooves 11 are provided on the upper and lower side walls of the hook seat 1 along the traction direction, a locking rod 2 is penetrated and movably connected in the hook groove 11, a shaft sleeve 3 is fixedly connected to the upper end of the hook seat 1, a rotating shaft 4 is rotatably connected in the shaft sleeve 3, the rotating shaft 4 is perpendicular to the direction of the hook groove 11, and the upper part of the locking rod 2 is fixedly connected to the rotating shaft 4.

[0019] Preferably, in combination with the above solution, in order to better fix the upper part of the locking rod 2 to the rotating shaft 4, the upper part of the locking rod 2 is bent in multiple sections to form a fixing portion 21, and the fixing portion 21 is fixedly connected to the peripheral wall of the rotating shaft 4 by welding. The fixing portion 21 can also be used as a handle for unlocking.

[0020] Preferably, in combination with the above solution, in order to facilitate the installation and fixation of the sleeve 3, a limiting bracket 12 is provided on the upper end of the hook seat 1 close to the traction direction, and the sleeve 3 is fixedly connected in the limiting bracket 12.

[0021] Preferably, in combination with the above solution, in order to prevent injuries, a protective plate 5 is provided on the side of the hook seat 1 away from the traction frame 10 .

[0022] Preferably, in combination with the above solution, in order to facilitate docking with a tractor, the left and right sides of the hook seat 1 are protruded with mounting portions 14, and the mounting portions 14 are connected to the tractor.

[0023] Preferably, in combination with the above solution, in order to facilitate connection by bolts, the mounting portion 14 is provided with a bolt hole 13 and is connected to the tractor by screw connection.

[0024] Principle of the utility model:

[0025] like Figure 1 As shown, the hook connection locking structure is connected to the tractor, and the traction frame 10 is connected to the device. When the towing hook 101 of the traction frame 10 moves forward and contacts the locking rod 2, the fixing portion 21 of the locking rod 2 drives the rotating shaft 4 to rotate, and the lower part of the locking rod 2 is lifted upward. After the towing hook 101 completely enters the U-shaped groove of the hook seat 1, the lower part of the locking rod 2 falls to the locking position, realizing the automatic locking function.
