[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Reference Figure 1-3 As shown, the high-strength automobile expansion kettle and bracket include a backboard bracket 1 and a kettle body 2. The front end surface of the backboard bracket 1 is symmetrically provided with a vertically arranged limiting guide rail 3. The front end surface of the limiting guide rail 3 is provided with a limiting slide groove 301 along its length direction. The rear end surface of the kettle body 2 is provided with a limiting block 4 matching the limiting slide groove 301. An inlet is provided at the top of the limiting guide rail 3. The limiting block 4 enters the interior of the limiting guide rail 3 from the inlet. The overall length of the limiting block 4 matches the limiting grass guard 301. The cross-section of the limiting block 4 is a T-shaped structure. The limiting block 4 cooperates with the limiting slide groove 301 of the limiting guide rail 3 to form front, back, left and rear limits for the kettle body 2 when the vehicle is driving. It is located on both sides of the kettle body 2 A mounting plate 5 is provided, which can be welded to the back plate bracket 1. A connecting shell 6 is provided on one side of the two mounting plates 5 close to the kettle body 2. Plug-in plates 7 matching the connecting shell 6 are provided on both sides of the kettle body 2. A connecting plate 602 fixedly connected to the mounting plate 5 is provided on the side of the connecting shell 6 close to the mounting plate 5. A accommodating groove 603 matching the plug-in plate 7 is provided on the connecting shell. When the limit block 4 enters the limiting slide groove 301, the plug-in plate 7 enters the accommodating groove of the connecting shell 6 to further limit the kettle body 2. It cooperates with the limiting guide rail 3 to support the kettle body 2 from the rear end face and both sides of the kettle body 2, so that the overall support of the kettle body 2 is better.

[0019] A fastening screw 601 and a screw drive assembly 8 for driving the fastening screw 601 to form a connection with the plug-in board 7 are provided on the connecting shell 6. The screw drive assembly 8 drives the fastening screw 601 to move horizontally back and forth, so that the plug-in board 7 is locked inside the connecting shell 6 to limit the upward and downward movement of the plug-in board 7, so that the kettle body 2 is limited on the back plate bracket 1. No specific external tools are required to operate the fastening screw, and the operation is convenient.

[0020] A through first connecting hole 604 is provided on the front end face of the connecting shell 6, a through second connecting hole 701 is provided on the plug-in board 7, and a locking groove 605 is provided on the rear end face inside the connecting shell 6. The first connecting hole 604, the second connecting hole 701 and the locking groove 605 are interconnected and are on the same central axis. One end of the fastening screw 601 is transmission-connected to the screw drive assembly 8, and the other end is threadedly connected to the first connecting hole 604, the second connecting hole 701 and the locking groove 605. The fastening bolt 601 is threadedly connected to the first connecting hole 604, the second connecting hole 701 and the locking groove 605 in sequence along with the screw drive assembly 8, making the connection between the kettle body 2 and the back plate bracket 1 more firm and stable.

[0021] The screw drive assembly 8 includes an annular slide rail 801 provided on the front end surface of the connecting shell 6, a knob 802 provided on the annular slide rail 801 is rotated, and an annular groove matching the annular slide rail 801 is provided on the knob 802. The knob 802 is stably rotated on the annular slide rail 801 through the annular groove. The annular slide rail 801, the knob 802 and the first connecting hole 604 are on the same central axis. One end of the fastening screw 601 passes through the annular slide rail 801 and is threadedly connected to the knob 802. Since one end of the fastening bolt 601 is connected to the knob 802 is threadedly connected, and the rotation of the knob 802 drives the fastening screw 601 to move back and forth horizontally, so that the fastening screw 601 is threadedly connected to the first connecting hole 604, the second connecting hole 701, and the locking groove 605. No special tools are required to operate the fastening screw 601. By rotating the knob 802, the fastening screw 601 is driven to separate from the first connecting hole 604, the second connecting hole 701, and the locking groove 605, and the kettle body 1 can be picked up. It is easy to install and disassemble, and it is more convenient to replace and maintain the expansion kettle later.

[0022] On the front end face of the backplate bracket 1, a supporting plate 9 is provided at the bottom end of the kettle body 2. The upper surface of the supporting plate 9 is in conflict with the bottom end of the kettle body 2, forming support for the kettle body 2, further improving the support of the kettle body 2 on the backplate bracket 1, and stop plates 10 in a vertically upward state are provided on both sides of the supporting plate 9. The two sides of the stop plate 10 are in conflict with the bottom ends of both sides of the kettle body 2. The stop plate 10 is located on the inner side of the connecting shell 6 and is staggered with the plug-in plate 7 to form support and limit on both sides of the kettle body 2, making the kettle body 2 more stable during driving of the vehicle.

[0023] At both ends of the kettle body 2, a plurality of reinforcing protrusions 201 are evenly spaced from top to bottom, and edge reinforcing ribs 202 are provided at the outer periphery of both ends of the kettle body 2. The reinforcing protrusions 201 and the edge reinforcing ribs 202 are equivalent to effectively increasing the wall thickness of the kettle body 2, increasing the structural strength and rigidity of the kettle body 2, making it more pressure-resistant, and extending the service life of the kettle body 2.

[0024] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the scope of protection of the present invention.
