DETAILED DESCRIPTION

[0020] like Figure 1 、 2 As shown, the present invention provides a rotatable carrier that can be rotated so that the bag opening faces the operator when loading items. The carrier includes a running mechanism 1 and a carrier body. The carrier body shown in the figure is a bag assembly 2, which is detachably mounted on the lower end of the running mechanism 1.

[0021] like Figure 2 、 3As shown in Figures 4, 6, and 7, the walking mechanism 1 includes a walking part, which includes a base 1.1 and rollers on the base. The lower end of the base 1.1 is connected to a boom 1.2, and a rotation positioning assembly is installed on the boom 1.2. The rotation positioning assembly includes an upper cam 1.4 and a lower cam 1.3, and the upper cam is located above the lower cam. The lower cam 1.3 is fixedly mounted on the lower end of the boom 1.2, and the boom 1.2 passes through the upper cam 1.4. The upper cam 1.4 can rotate relative to the boom and can also move up and down relative to the boom. The top of the upper cam 1.4 is connected to a hanger 1.5, and both ends of the hanger 1.5 are provided with drooping ears, and the ears are provided with an inclined hanging groove 1.6, and the hanging groove is inclined upward. The cloth bag assembly 2 is hung on the hanger 1.5, and the hanger 1.5 can rotate with the upper cam 1.4, thereby driving the cloth bag assembly 2 to rotate, so that the cloth bag assembly can be directed towards the operator, which is convenient for loading items.

[0022] like Figure 6 、 7 As shown, the lower cam 1.3 is provided with an upper spiral surface 1.3.1, and the upper spiral surface 1.3.1 is provided with at least one positioning hole 1.3.2. The positioning hole shown in the figure is a spherical hole. The upper cam 1.4 is provided with a lower spiral surface 1.4.1. Under the action of gravity, the lower spiral surface 1.4.1 of the upper cam fits with the upper spiral surface 1.3.1 of the lower cam 1.3. Figure 3 The figure shows the upper and lower helical surfaces in contact. If upper cam 1.4 is rotated, lower helical surface 1.4.1 becomes misaligned with upper helical surface 1.3.1, and upper cam 1.4 rotates and rises. After 180 degrees, it reaches its highest point, at which point the two helical tips of the upper and lower cams face each other. Mounting hole 1.4.2 is defined at the lowest point of lower helical surface 1.4.1 of upper cam 1.4. A movable limit post 1.7 is mounted in mounting hole 1.4.2, allowing it to move up and down. When the upper cam 1.4 is rotated and the lowest point of the lower spiral surface 1.4.1 reaches a certain positioning hole 1.3.2, the mounting hole and the positioning hole are aligned. Under the action of gravity, the end of the limit post 1.7 is inserted into the positioning hole 1.3.2, so that the upper cam 1.4 maintains the rotation angle and does not move, thereby preventing the upper cam 1.4 from resetting under the action of gravity, thereby facilitating the operator to place the object. After the placement is completed, the operator slightly rotates the upper cam to cause the limit post 1.7 to slide out of the positioning hole 1.3.2, thereby causing the upper cam to reset due to gravity. A spring (not shown) can be provided in the mounting hole 1.4.2, with its two ends respectively resting against the top of the mounting hole and the top of the limit post. The provision of the spring can make the limit post 1.7 better inserted into the positioning hole 1.3.2 and not easily removed from the positioning hole 1.3.2.

[0023] like Figure 3 、 5As shown, the cloth bag assembly 2 includes a sealing frame 2.1 and a cloth bag 2.2. A pair of limiting plates 2.3 are mounted on one of the long sides of the sealing frame 2.1. The lower ends of the limiting plates 2.3 are provided with two opposing bent portions 2.3.1. When the long side is hung on the hanging slot 1.6 of the hanging frame 1.5, the two limiting plates 2.3 are located outside the two hanging ears of the hanging frame 1.5, and their bent portions 2.3.1 extend into the lower ends of the hanging ears. This prevents the cloth bag assembly from falling out of the hanging slot if the cloth bag is accidentally lifted. To separate the cloth bag assembly from the traveling mechanism, the sealing frame must be rotated so that the bent portion 2.3.1 moves forward of the hanging slot opening, and then the bag assembly can be removed from the hanging slot.

[0024] The cloth bag mentioned in the present invention can be made of cotton textiles, plastic materials, or non-woven materials. It should not be understood that it is made of a specific material. Any cloth bag connected to a skeleton to achieve full or partial sealing to form a carrier is the cloth bag of the present invention.
