Detailed Description

The technical solution of the present invention is further explained with reference to the drawings and the embodiments.

Example 1:

as shown in fig. 1, the embodiment of the present invention provides a buffer device for weighing a liquid chlorine steel cylinder, which includes a support seat and a buffer arranged on the support seat, wherein the support seat includes a bottom plate 1 and backing plates 2 respectively arranged on two sides of the bottom plate 1, and the bottom plate 1 is fixed on the surface of the weighing device in a matching manner. The distance between the backing plates 2 is smaller than the diameter of the steel cylinders, so that the steel cylinders are not contacted with the bottom plate 1 when being placed on the backing plates 2 in parallel; and the space between the backing plates 2 is enough to stably place the steel cylinder, and the steel cylinder cannot roll off under the action of slight external force.

In the concrete scheme of this embodiment, the buffer is including setting up a plurality of telescopic sleeve 3 on bottom plate 1, telescopic sleeve 3 is elastic construction, at vertical direction elastic expansion, telescopic sleeve 3 sets up on the both sides center connection of backing plate 2 is not installed to bottom plate 1, when telescopic sleeve 3 is in balanced state not bearing, telescopic sleeve 3's surface height is higher than the height of the steel bottle least significant end when placing on backing plate 2. Therefore, the lowest point of the steel cylinder is firstly contacted with the telescopic sleeve 3 in the falling process, so that the falling impact force of the steel cylinder is relieved in the process of compressing and deforming the telescopic sleeve 3, and the function of buffering is achieved.

In a further scheme, the telescopic sleeve 3 comprises an inner cylinder 31 and an outer cylinder 32 which are vertically arranged, the bottom end of the outer cylinder 32 is fixed on the bottom plate 1, the top end of the outer cylinder 32 is open, the top of the inner cylinder 31 is closed, the bottom end of the inner cylinder 31 is open, the bottom end of the inner cylinder 31 partially extends into the outer cylinder 32, and a spring 33 is arranged between the bottom end of the inner cylinder 31 and the bottom end of the outer cylinder 32. Because the bottom end part of the inner cylinder 31 is always positioned in the outer cylinder 32, the inner cylinder 31 is limited by the inner wall of the outer cylinder 32 when moving up and down, so that the inner cylinder is always coaxial with the outer cylinder 32, the pressure in the vertical direction transmitted by the steel cylinder can be vertically transmitted to the spring 33, and the problem of stress inclination can not occur.

In this embodiment, the inner side of the top end surface of the backing plate 2 is preferably inclined downward to match the shape of the contact surface between the steel cylinder and the backing plate 2. Therefore, the steel cylinder can be placed on the backing plate 2 more stably and is less prone to rolling off from the side.

Example 2:

the remainder of this example is the same as example 1, except that: the number of the telescopic sleeves 3 is two, the telescopic sleeves are respectively arranged at the centers of two sides of the base plate 1 without the installation of the base plate 2, a connecting plate 4 is further arranged between the two telescopic sleeves 3, and the connecting plate 4 is arranged at the top of the telescopic sleeves 3, so that the upper surface of the connecting plate 4 is parallel to the top ends of the telescopic sleeves 3. The contact area between the buffer and the steel cylinder can be enlarged through the connecting plate 4, so that the pressure of the steel cylinder is transmitted to the telescopic sleeve 3 below more uniformly.

In the preferred scheme, protruding layer boards 5 are further arranged on two sides of the connecting board 4, and the layer boards 5 are arc-shaped boards matched with the side shapes of the steel cylinders. The supporting plate 5 and the connecting plate 4 are better matched and supported at the bottom of the steel cylinder, and the auxiliary fixing effect can be achieved. Meanwhile, the steel cylinder can be more accurately received by the buffer when falling.

Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
