Problems solved by technology

But too long hoppers are not convenient for vehicle transportation. We hope that by dividing the hoppers into segmented structures, stacking them when not in use, and allowing them to be stretched when in use, so as to achieve flexible use
However, none of the existing fastening devices is suitable for installation on large-scale active devices such as mixer trucks, and meets the requirements of movable connection hoppers with a simple and beautiful structure.

Embodiment

[0017] like figure 1 As shown, the present invention includes a base body 1, a positioning rod 2 and a locking sleeve 3, and the base body 1 is a cuboid with a lower right corner cut off. The locking sleeve 3 of this embodiment is formed by a plurality of hollow cylinders arranged at intervals, and the locking sleeve 3 is located on the left side of the top of the base body 1 . The positioning rod 2 of this embodiment is inserted into the inside of the locking sleeve 3, and a handle 4 is also provided in the vertical direction in the middle of the positioning rod 2. The handle 4 includes a ball and a cross bar with a bending degree, and the cross bar connects the ball and the positioning The rod 2 and the corresponding locking sleeve 3 below the handle 4 are provided with a transverse opening on the top. In this embodiment, an elongated groove 5 is provided on the upper left side of the base body 1 , and a section of the locking sleeve 3 is located on the left side of the gro...

Abstract

The invention discloses a device for locking a movable hopper. The device comprises a base body (1), a positioning rod (2) and a locking sleeve (3), wherein the locking sleeve (3) is formed by a plurality of sections of hollow cylinders at intervals and positioned on the left side of the top of the base body (1), the positioning rod (2) is inserted into the locking sleeve (3), and a strip-shaped groove (5) is formed above the left side of the base body (1). Through the structure, the device uses a push-pull type structure, and is very suitable for being installed on a concrete mixing truck, so as to realize the movable connection of the flip type hopper.

Description

technical field [0001] The invention relates to a locking mechanism, in particular to a device for locking a movable hopper. Background technique [0002] At present, locking mechanisms are widely used in various industries, and they are also required in concrete mixer trucks. The existing locking mechanisms are not only unsightly, but also complicated to operate. Concrete mixer truck is a special vehicle used for long-distance transportation of concrete. There is a special mixing device on the mixer truck to continuously mix the concrete in it to prevent the concrete from solidifying during transportation. There is also a hopper on the mixer truck for taking the concrete on the truck at any time, which is frequently used, so the hopper is usually placed directly on the mixer truck. Usually the length of the hopper is designed to be relatively long for easy retrieving. However, a too long hopper is not convenient for vehicle transportation. We hope that by dividing the hop...
