Description

Technical Field

[0001] This utility model relates to the field of anti-tilt wheel technology, specifically a quick anti-tilt wheel folding structure for a handcart. Background Technology

[0002] Golf bag trolleys are a convenient means of transporting golf bags. The golf balls, clubs, and other equipment inside make the bags quite heavy, and carrying them manually is laborious. Using a golf bag trolley can save manpower.

[0003] A typical golf bag cart consists of a frame, casters, motor wheels, and anti-roll wheels. When in use, the golf bag is placed on the frame and secured. The motor wheels drive the cart to move, the casters control the direction of movement, and the anti-roll wheels prevent the cart from tipping over.

[0004] Regarding the aforementioned technical conditions, there is still a drawback: the anti-roll wheels of current golf carts cannot be folded and stored.

[0005] Based on this, this utility model designs a quick anti-tilt wheel folding structure for a handcart to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a quick anti-tipping wheel folding structure for a handcart to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a quick anti-tilt wheel folding structure for a handcart, comprising a cart body and anti-tilt wheels, a mounting base fixedly connected to the cart body, a mounting plate connected to the cart body, a fixing rod fixedly connected to the mounting plate, two fixing rods mirror-arranged on the mounting plate, a wheel rotatably connected to one end of the fixing rod, the other end of the fixing rod rotatably connected to the mounting base, a tension spring connected to the cart body, a mounting rod fixedly connected to the fixing rod, and one end of the tension spring connected to the mounting rod.

[0008] Preferably, a limiting block is fixedly connected to the mounting base, and the mounting plate abuts against the limiting block.

[0009] Preferably, a connecting screw is inserted into the limiting block, a sleeve is fixedly connected to the vehicle body, the connecting screw is inserted into the sleeve, one end of the tension spring is sleeved on the connecting screw, a fastening nut is threaded onto the connecting screw, and the tension spring is between the fastening nut and the sleeve.

[0010] Preferably, a limiting groove is provided on the mounting rod, and one end of the tension spring is sleeved in the limiting groove.

[0011] Preferably, the mounting base is provided with a rotating rod, which is inserted into the fixed rod. One end of the rotating rod is threaded with a fixing nut, which abuts against the fixed rod.

[0012] In summary, this application has the following beneficial technical effects: When it is necessary to fold and store the wheels, the wheel is pressed down by the mounting plate to bring it closer to the bottom of the vehicle body. During this process, the tension spring rotates on the connecting screw and mounting rod as the wheel rotates. The tension spring is stretched first, and when the wheel touches the bottom of the vehicle body, the tension spring contracts. At this time, under the tension of the tension spring, the wheel is quickly and stably folded and stored at the bottom of the vehicle body, achieving the effect that the anti-roll wheel can be folded and stored on the golf bag.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0023] A quick anti-tilt wheel folding structure for a handcart includes a cart body 1 and anti-tilt wheels 5. A mounting base 13 is fixedly connected to the cart body 1, and a mounting plate 2 is connected to the cart body 1. A fixing rod 6 is fixedly connected to the mounting plate 2, and two fixing rods 6 are mirror images of each other on the mounting plate 2.

[0024] Wheel 5 is rotatably connected to one end of fixed rod 6, and the other end of fixed rod 6 is rotatably connected to mounting base 13. Tension spring 3 is connected to vehicle body 1, and mounting rod 4 is fixedly connected to fixed rod 6, with one end of tension spring 3 connected to mounting rod 4.

[0025] When wheel 5 is in the unfolded state, tension spring 3 is in the retracted state, mounting plate 2 abuts against mounting base 13, and wheel 5 abuts against the ground. At this time, wheel 5 acts as an anti-tilt device. When it is necessary to fold and store wheel 5, press wheel 5 down to bring it closer to the bottom of vehicle body 1. During this process, tension spring 3 is first stretched. When wheel 5 abuts against the bottom of vehicle body 1, tension spring 3 is in the retracted state. At this time, under the tension of tension spring 3, wheel 5 is stably folded and stored at the bottom of vehicle body 1.

[0026] A limiting block 10 is fixedly connected to the mounting base 13. The mounting plate 2 abuts against the limiting block 10. The limiting block 10 plays a limiting role to prevent the fixing rod 6 from rotating too much around the mounting base 13 when the wheel 5 is unfolded, which would affect the anti-tilt effect of the wheel 5.

[0027] The limiting block 10 is provided with a connecting screw 8. The body 1 is fixedly connected with a sleeve 11. The sleeve 11 is on the connecting screw 8. One end of the tension spring 3 is sleeved on the connecting screw 8. The connecting screw 8 is threadedly connected with a fastening nut 12. The tension spring 3 is between the fastening nut 12 and the sleeve 11. With the fastening nut 12, the sleeve 11 and the connecting screw 8, one end of the tension spring 3 can rotate. When the wheel 5 is folded and stored, the tension spring 3 can easily fix the wheel 5 with its tension force.

[0028] A limiting groove 9 is provided on the mounting rod 4. One end of the tension spring 3 is fitted into the limiting groove 9. The limiting groove 9 makes it difficult for one end of the tension spring 3 to fall off the mounting rod 4, while allowing one end of the tension spring 3 to rotate on the mounting rod 4, which facilitates the use of the tension spring 3.

[0029] A rotating rod 7 is inserted into the mounting base 13, and a fixing groove is provided on the fixing rod 6. The mounting base 13 is located in the fixing groove, the rotating rod 7 is inserted into the fixing rod 6, the rotating rod 7 passes through the fixing groove and extends outside the fixing groove, one end of the rotating rod 7 abuts against one side of the fixing rod 6, and the other end of the rotating rod 7 is threaded with a fixing nut. The fixing nut abuts against the other side of the fixing rod 6. The rotating rod 7 and the fixing nut cause the fixing rod 6 to rotate and be mounted on the mounting base 13.

[0030] The implementation principle of this embodiment is as follows: When it is necessary to fold and store the wheel 5, the mounting plate 2 presses the wheel 5 down to make the wheel 5 move closer to the bottom of the vehicle body 1. During this process, the tension spring 3 rotates on the connecting screw 8 and the mounting rod 4 as the wheel 5 rotates. The tension spring 3 is stretched first. When the wheel 5 touches the bottom of the vehicle body 1, the tension spring 3 contracts. At this time, under the tension of the tension spring 3, the wheel 5 is quickly and stably folded and stored at the bottom of the vehicle body 1, achieving the effect that the anti-roll wheel can be folded and stored on the ball bag car.
