Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1-4, a low temperature resistant polyurethane roller comprises a bracket 1, a spring 2, a telescopic rod 3, a chute 4, a cutting hole 5, a fixed shaft 6, a roller 7, a fixed frame 8 and a mudguard 9, wherein the spring 2 is fixed above the inside of the bracket 1, the telescopic rod 3 is fixed in the middle of the inside of the spring 2, and the telescopic rod 3 can prevent the spring 2 from being bent easily when the spring 2 deforms; the two sides of the inside of the bracket 1 are both provided with sliding chutes 4, a fixed shaft 6 is arranged between the two sliding chutes 4, and the fixed shaft 6 can slide up and down in the two sliding chutes 4; the top of fixed axle 6 is installed mount 8, and the upper end of spring 2 supports and leans on support 1, and the lower extreme of spring 2 supports and leans on mount 8, and the surface of fixed axle 6 has cup jointed gyro wheel 7.

As shown in fig. 1 and 2, the spring 2 is positioned above the roller 7, and the spring 2 is made of manganese steel, and the spring 2 is more durable due to the good compression resistance of the manganese steel. The roller 7 is rotatably connected with the fixed shaft 6, so that the roller 7 can rotate on the fixed shaft 6, and the two ends of the fixed shaft 6 are slidably connected with the sliding grooves 4, so that the fixed shaft 6 can slide on the sliding grooves 4.

As shown in fig. 2 and 3, a cutting hole 5 penetrates through the lower portion of the outer surface of the bracket 1, the cutting hole 5 is located above one side of the fixing shaft 6, and the distance between the cutting hole 5 and the lower end surface of the bracket 1 is greater than the radius of the roller 7, when the fixing shaft 6 moves above the cutting hole 5, a user can insert a bolt into the cutting hole 5, so that the bolt intercepts the bottom of the fixing shaft 6, the roller 7 does not contact with the ground, and the roller 7 fails to roll relative to the ground. When the lower surface of the roller 7 is positioned below the bracket 1, the roller 7 can roll relative to the ground; when the lower surface of the roller 7 is inside the frame 1, the roller 7 is not active.

As shown in fig. 2 and 4, a mudguard 9 is fixed at the bottom of the bracket 1, the mudguard 9 is arc-shaped, and the mudguard 9 is positioned outside the roller 7, so that the mudguard 9 can scrape off sundries on the surface of the roller 7, and the roller 7 is cleaner.

The working principle is as follows: firstly, a worker installs the roller 7 on the draw-bar box, then when the user moves the draw-bar box, the roller 7 can rotate on the fixed shaft 6, when sundries are adhered to the surface of the roller 7, the sundries rotate along with the surface of the roller 7, when the sundries pass through the mudguard 9, the mudguard 9 on the outer side of the roller 7 can scrape the sundries, so that the sundries are not adhered to the roller 7 any more, the roller 7 is cleaner after walking, and meanwhile, when the roller 7 needs to be fixed to prevent the draw-bar box from moving; the user can press gyro wheel 7, because the both ends of fixed

axle

6 and 4 sliding connection of spout, make when gyro wheel 7 receives to press, fixed axle 6 can be on spout 4 to the inside top of support 1 and remove, make mount 8 and the contact of spring 2, extrude spring 2 simultaneously, when fixed axle 6 position is located the plug hole 5 top through sliding, the user can use the bolt to insert in the plug hole 5, make the bolt intercept fixed axle 6 bottom, thereby make gyro wheel 7 can be in support 1 inside can not with ground contact, and then make the draw-bar box can stand still.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.

Although the terms bracket 1, spring 2, telescopic rod 3, sliding slot 4, cutting hole 5, fixed shaft 6, roller 7, fixing frame 8 and mudguard 9 are used more herein, the possibility of using other terms is not excluded. These terms are used merely to more conveniently describe and explain the nature of the present invention; they are to be construed in a manner that is inconsistent with the spirit of the invention.
