Description

Technical Field

[0001] The utility model relates to the technical field of transportation tools, and particularly relates to a flatbed truck with a self-locking structure when leaving the vehicle. Background Technique

[0002] Flatbed trucks are available in a variety of materials according to different usage environments: stainless steel, steel, plastic, aluminum, etc. Stainless steel trolleys are widely used in industries such as food, medical, and chemical industries. Steel trolleys are widely used in industries such as industry, warehousing, and electronics. Plastic and aluminum trolleys are generally used in industries such as small warehouses, stores, and shopping malls due to their light weight and convenient carrying.

[0003] When the existing flatbed trucks are in transportation, it is easy to forget to lock the vehicle, often resulting in the situation of the vehicle slipping, and they do not have an alarm function, which has certain potential safety hazards.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a flatbed truck with a self-locking structure when leaving the vehicle is proposed, in order to achieve a more practical and valuable purpose. Content of the Utility Model

[0005] The purpose of the utility model is to provide a flatbed truck with a self-locking structure when leaving the vehicle, so as to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A flatbed truck with a self-locking structure when leaving the vehicle, including a flatbed main body and a fixing ring. A card slot is opened on one side of the flatbed main body, and a self-locking mechanism when leaving the vehicle is installed inside the card slot. The self-locking mechanism when leaving the vehicle includes a shaft rod, a non-slip arc plate, a folding rod, and a vibration alarm. A non-slip arc plate is arranged on one side of the bottom of the shaft rod, and a folding rod is arranged on one side of the top of the shaft rod. A vibration alarm is installed on the outer wall of the non-slip arc plate. A handrail is installed on one side of the top of the flatbed main body, and a clamping spring is arranged at the connection between the handrail and the folding rod. A fixing ring is sleeved and installed on the top of the handrail, and an extending soft plate extends from the outer end of the fixing ring, and a traction rod is installed at the other end of the extending soft plate.

[0007] Further, a front positioning plate is arranged on one side of the top wall of the flatbed main body, and a rear positioning plate is arranged on the other side of the top wall of the flatbed main body. A fixing sleeve is installed inside the front positioning plate, and a limiting rod is arranged through the inside of the fixing sleeve.

[0008] Further, a fitting groove is opened on the inner side of the bottom of the rear positioning plate.

[0009] Further, a lithium battery motor is arranged at the bottom of the flatbed main body for driving the wheels to rotate.

[0010] Further, a rotating structure is formed between the anti-slip arc plate and the folding rod through the shaft rod and the card slot.

[0011] Further, an elastic connection is formed between the folding rod and the handrail through the clamping spring.

[0012] Further, a sleeve-shaped movable connection is formed between the fixing ring and the folding rod, and the folding rod is matched with the handrail through the extending flexible plate.

[0013] The utility model provides a flatbed truck with a self-locking structure when leaving the vehicle, and has the following beneficial effects:

[0014] 1. In the utility model, the fixing ring fixed on the folding rod uses the extending flexible plate to extend the length, and the flatbed truck is moved by pulling the towing rod.

[0015] When towing and moving, it will cause the folding rod to approach the handrail end, so as to avoid the anti-slip arc plate at the bottom of the folding rod from contacting the wheels of the flatbed truck, ensuring the operation of the flatbed truck.

[0016] When the towing operation is disengaged, the towing rod at the top is not restricted by external forces, so it disengages from the handrail, causing the folding rod to move away from the handrail end, making the anti-slip arc plate at the bottom contact the wheels of the flatbed truck, preventing the flatbed truck from moving.

[0017] A clamping spring is arranged at the connection between the folding rod and the handrail, which can provide elastic support force, making the anti-slip arc plate contact the wheel tightly and playing the role of locking the wheel.

[0018] A vibration alarm is also arranged on the outer side of the anti-slip arc plate to monitor the vibration amplitude of the anti-slip arc plate. When vibration is monitored, a beeping sound is emitted for warning, and it can also prompt the operator to manually lock the bottom wheels, enhancing the safety performance of the flatbed truck.

Specific implementation mode

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-3 , the present invention provides a technical solution: a flatbed truck with an off-vehicle self-locking structure, including a flat plate main body 1 and a fixed ring 7. A card slot 101 is opened on one side of the flat plate main body 1, and an off-vehicle self-locking mechanism 2 is installed inside the card slot 101. The off-vehicle self-locking mechanism 2 includes a shaft rod 201, an anti-slip arc plate 202, a folding rod 203 and a vibration alarm 204. An anti-slip arc plate 202 is arranged on one side of the bottom of the shaft rod 201, and a folding rod 203 is arranged on one side of the top of the shaft rod 201. A vibration alarm 204 is installed on the outer wall of the anti-slip arc plate 202. A handrail 4 is installed on one side of the top of the flat plate main body 1, and a clamping spring 5 is arranged at the connection between the handrail 4 and the folding rod 203. A fixed ring 7 is sleeved and installed on the top of the handrail 4, and an extending flexible plate 701 extends from the outer end of the fixed ring 7, and a towing rod 702 is installed at the other end of the extending flexible plate 701; a front positioning plate 3 is arranged on one side of the top wall of the flat plate main body 1, and a rear positioning plate 302 is arranged on the other side of the top wall of the flat plate main body 1. A fixed sleeve 301 is installed inside the front positioning plate 3, and a limiting rod 303 penetrates through the inside of the fixed sleeve 301; a fitting groove 304 is opened on the inner side of the bottom of the rear positioning plate 302; a lithium battery motor 6 is arranged at the bottom of the flat plate main body 1 for driving the wheels to rotate; the anti-slip arc plate 202 and the folding rod 203 form a rotating structure through the shaft rod 201 and the card slot 101; the folding rod 203 forms an elastic connection with the handrail 4 through the clamping spring 5; the fixed ring 7 and the folding rod 203 are movably connected in a sleeve shape, and the folding rod 203 is matched with the handrail 4 through the extending flexible plate 701.

[0026] With the fixed ring 7 fixed on the folding rod 203, the extension length is utilized by the extending flexible plate 701, and the position of the flatbed truck is moved by pulling the towing rod 702.

[0027] When being towed and moved, it will prompt the folding rod 203 to approach the 4th end of the handrail rod, so as to prevent the anti-slip arc plate 202 at the bottom of the folding rod 203 from contacting the wheels of the flatbed truck and ensure the operation of the flatbed truck;

[0028] When the towing operation is disengaged, the towing rod 702 at the top is not restricted by external forces, then it disengages from the handrail rod 4, makes the folding rod 203 move away from the 4th end of the handrail rod, and makes the anti-slip arc plate 202 at the bottom contact the wheels of the flatbed truck to prevent the flatbed truck from moving;
