[0026] Example 1,

[0027] like Figures 1 to 4As shown, a lock seat and side beam reinforcement connection structure is mainly used for the installation and fixation of twist lock locks in container semi-trailers. The twist lock lock is installed on the inner side of the outer side beam 2 in the semi-trailer frame, including a core rod, a lock seat 1 sleeved on the core rod, a lock head fixed to the top of the core rod, and a rotating handle fixed to the bottom of the core rod, wherein the lock seat 1 includes an upper top plate 11, two vertical plates 12 and an end side plate 13, the two vertical plates 12 are vertically welded and fixed to the bottom of the upper top plate 11, spaced parallel to each other and perpendicular to the upper top plate 11, the vertical plates 12 are processed and set as an extended version, and the end side plates 13 are also vertically fixed to the bottom of the upper top plate 11, located at the outer end of the vertical plate 12 and welded and fixed to the vertical plate 12, and the cross-section of the end side plates 13 and the two vertical plates 12 is π-shaped. The leading edge of the upper top plate 11 is welded and fixed to the rear side surface of the front side beam 3 in the frame, and a reinforcing plate 5 and an extension plate 6 are arranged between the rear edge of the upper top plate 11 and the rear side beam 4 and the outer side beam 2 in the frame. The reinforcing plate 5 and the extension plate 6 are an integral bent-molded structure, wherein the reinforcing plate 5 is a long strip plate, and the extension plate 6 is located on one side of the reinforcing plate 5 close to one end of the outer side beam 2. The reinforcing plate 5 is arranged horizontally, and the extension plate 6 is arranged obliquely upward.

[0028] During use, the reinforcing plate 5 is placed between the upper plate 11 and the rear side beam 4, and its position is adjusted so that the inner end is close to the inner side of the vertical plate of the outer side beam 2. The reinforcing plate 5 is then welded to the upper plate 11 and the rear side beam 4; at this time, the extension plate 6 extends obliquely upward, and its upper end abuts the bottom surface of the upper horizontal plate in the outer side beam 2, and is also connected by a full welding fixation method. At the same time, the inner ends of the two vertical plates 12 in the lock base 1 extend to the inner side of the vertical plate of the outer side beam 2 and are welded fixed, and the front end of the end side plate 13 extends to the rear side of the front side beam 3 and is welded fixed, thereby improving the fixing strength of the entire lock base 1 and the side beam. Furthermore, the upper surface of the reinforcing plate 5 is also welded and fixed with a spacer 7 along its length, located beside the upper plate 11 in the lock base 1, and its upper end surface is flush with the upper end surface of the outer side beam 2, ensuring the horizontal connection stability of the lower contact surface of the container and preventing the container from shifting when loaded.

[0029] Example 2,

[0030] Combine Figures 5 to 8As shown, a lock seat and side beam reinforcement connection structure, its technical solution is roughly similar to the technical solution described in the above embodiment 1, and a reinforcement plate 5 and an extension plate 6 are also set between the lock seat 1 and the rear side beam 4 and the outer side beam 2, wherein the reinforcement plate 5 is a long strip plate structure, and the extension plate 6 is located on the side of the reinforcement plate 5 close to one end of the outer side beam 2, and is tilted upward. It is bendably fixedly connected to the reinforcement plate 5, and the upper half of the connection is flexibly connected to the edge of the reinforcement plate 5, and the lower half is provided with a deformation slot 8; the extension plate 6 is located on the side of the reinforcement plate 5 close to one end of the outer side beam 2, and is tilted upwardly. It is bendably fixedly connected to the reinforcement plate 5. The bottom of the movable end of the extension plate 6 is also fixed with a connecting ear, and a retractable support rod 9 is hinged on the connecting ear. The retractable support rod 9 adopts a telescopic screw structure, including an upper screw, a lower screw and a threaded sleeve mounted on the outside thereof. The upper end of the upper screw is connected to the connecting ear and abuts against it, and the lower end thereof is threadedly mounted inside the upper end of the threaded sleeve. The lower screw is coaxially threadedly inserted into the bottom of the threaded sleeve, and its lower end can abut against the upper side of the lower cross plate of the outer side beam 2, and the extension of the lower screw is controlled by rotating the threaded sleeve.

[0031] The lock seat 1 also includes an upper top plate 11, two vertical plates 12 and end side plates 13. The two vertical plates 12 are vertically welded and fixed to the bottom of the upper top plate 11, parallel to each other and perpendicular to the upper top plate 11. The vertical plates 12 are processed and set to an extended version compared to the existing structural shape in use. The end side plates 13 are also vertically fixed to the bottom of the upper top plate 11, located at the outer end of the vertical plate 12 and welded to the end of the vertical plate 12. The cross-section of the end side plates 13 and the two vertical plates 12 is π-shaped. The front edge of the above-mentioned upper top plate 11 is welded and fixed to the rear side surface of the front side beam 3 in the frame, and the above-mentioned reinforcement plate 5 is installed between the rear edge of the upper top plate 11 and the rear side beam 4 in the frame. The bottom of the rear edge of the upper top plate 11 is also fixed with a plurality of positioning beads 14 arranged at intervals along a straight line. Correspondingly, the reinforcement plate 5 is provided with a plurality of long slots 51 arranged at intervals along a straight line. The above-mentioned positioning beads 14 can be slidably installed in the corresponding long slots 51. The diameter of the positioning beads 14 is consistent with the width of the long slots 51, and the height thereof protruding from the upper top plate 11 is equal to the thickness of the reinforcement plate 5.

[0032] When in use, the reinforcing plate 5 is placed between the upper top plate 11 and the rear side beam 4, and the positioning beads 14 at the bottom of the upper top plate 11 are correspondingly accommodated in the long slots 51 of the reinforcing plate 5, which is convenient for limiting the reinforcing plate 5 to slide left and right in the same straight line to prevent it from deviating forward and backward during the adjustment process until its inner end horizontally presses against the vertical plate inner side of the outer side beam 2, and then welds the reinforcing plate 5 with the upper top plate 11 and the rear side beam 4; at this time, the extension plate 6 is inserted into the outer side beam 2 and does not contact the upper cross plate of the outer side beam 2. Then, the above-mentioned threaded sleeve is rotated so that the lower end of the lower screw rod vertically presses against the lower cross plate of the outer side beam 2, thereby driving the upper end of the upper screw rod to push the extension plate 6 upward, so that the extension plate 6 rotates upward and fits closely with the outer side beam 2, and then is welded and fixed. At the same time, full welding is performed in the above-mentioned deformed slot 8 to achieve a bendable fixed connection between the extension plate 6 and the reinforcing plate 5. At the same time, the inner ends of the two vertical plates 12 in the lock seat 1 extend to the inner side of the vertical plate of the outer side beam 2 and are welded to it. The front end of the end side plate 13 extends to the rear side of the front side beam 3 and is welded to it to enhance the fixing strength of the entire lock seat 1 and the side beam. Similarly, a spacer 7 is welded to the upper surface of the reinforcement plate 5 along its length. It is located next to the upper top plate 11 in the lock seat 1. Its upper end surface is flush with the upper end surface of the outer side beam 2 to ensure the horizontal stability of the lower contact surface of the container and prevent the container from shifting and prying when loaded.

[0033] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
