[0010] Along the circumferential direction, an arc-shaped groove is provided on the inner side surface of the adjustment ring, and the depth of the arc-shaped groove gradually changes along the arc direction;

[0011] A baffle is arranged between the roller and the adjusting ring. A clamping column through the baffle has one end facing the clamping groove and the other end provided with a cap head placed in the arc groove. The clamping column sleeve is provided with a spring for pressing the baffle and the cap head.

[0012] The above-mentioned clamping column and arc groove are 2 sets.

[0013] Furthermore, the clamping column is symmetrical based on the axis of the roller.

[0014] The baffle is a side plate of the U-shaped frame.

[0015] Furthermore, the top of the U-shaped frame is fixedly connected to a shaft rod, and the shaft rod is used to connect to the shaft column at the bottom of the vehicle body.

[0016] Furthermore, the horizontal cross-section of the shaft is circular.

[0017] Furthermore, the horizontal cross-section of the shaft is rectangular.

[0018] The utility model is beneficial in that:

[0019] The utility model is a wheel brake structure suitable for outdoor camp trolleys. The side plate of the existing U-shaped frame of the roller is used as a base plate, and an adjustment ring coaxial with the roller is arranged on the outer side thereof. The elastic clamping column is pressed by rotating the adjustment ring to make it extend into or extend out of the clamping groove on the outer side of the roller to form a braking effect. The utility model has a simple structure, is easy to use, and is easy to disassemble, repair, and clean. It has a good braking effect on the roller and a high braking precision. It does not require the roller to be in a specific position, and it does not need to consider the problem that the adjustment ring may rotate with the rotating shaft. It has strong practicality and wide applicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] The invention discloses a wheel brake structure suitable for an outdoor camp trolley, which is composed of an adjusting ring 2, an elastic clamping column 4 and a roller.

[0028] The outer side surface of the roller is provided with a plurality of slots, and preferably, the slots are arranged in the radial direction.

[0029] The U-shaped frame 8 holds the roller, and the two ends of the roller's rotating shaft pass through the two side plates 1 of the U-shaped frame 8. The adjusting ring 2 is coaxially arranged outside the side plate 1, such as Figure 3 As shown, the adjusting ring is fixed and limited by the cap head at the end of the rotating shaft.

[0030] The side plate 1 of the U-shaped frame 8 is provided with a through hole facing the slot, and the clamping column 4 is placed in the through hole, with one end facing the slot and the other end placed on the outer side of the side plate 1, and a cap is provided at the end. A spring 5 is sleeved on the outer side section of the clamping column 4, one end of the spring 5 presses against the cap, and the other end presses against the side plate 1. Preferably, the through hole and the clamping column 4 are a pair, and are symmetrical based on the rotation axis.

[0031] An arc groove 6 is provided along the circumferential direction on the inner side surface of the adjusting ring 2 , and the depth of the arc groove 6 changes gradually along the arc direction. The cap head of the clamping column 4 is placed in the arc groove 6 .

[0032] When the adjusting ring 2 is rotated, the arc groove 6 with a gradually changing depth presses the cap head, so that the clamping column 4 slides along the through hole, and the other end extends into the clamping groove, forming a braking effect on the roller. When the adjusting ring 2 is rotated in the opposite direction, the clamping column 4 moves to the outer end under the elastic force of the spring 5, so that the roller is out of the braking effect.

[0033] Preferably, a sealing cap 3 for blocking the ring hole can be provided at the outer end of the rotating ring, thereby protecting the cleanliness of the rotating shaft and making the vehicle body more suitable for outdoor operations.

[0034] The top of the U-shaped frame 8 is fixedly connected to the shaft rod 7, and the shaft rod 7 is used to connect to the shaft column at the bottom of the vehicle body.

[0035] The horizontal cross section of the shaft rod 7 can be circular or rectangular. When it is rectangular, the roller is a fixed wheel, and when it is circular, the roller can be a universal wheel.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the above embodiments do not limit the utility model in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the utility model.
