Description
Technical Field
[0001] The utility model relates to the technical field of safe gas filling, in particular to a gas filling protection device. Background Art
[0002] Gas cylinder filling refers to the process of filling various types of gas cylinders with gas or liquid media stored in pressure vessels or gas generating devices using special filling facilities. In actual production, the most common equipment for filling gas cylinders is the flower basket filling platform, which has a transparent protective cover falling during the filling process, making it easier to observe the filling situation and avoid damage to the filling hose to personnel.
[0003] During filling, in order to avoid frequent handling of cylinders and facilitate gas filling, a gas cylinder rack is generally used to place the gas cylinders. However, the existing gas cylinder rack lacks a fixing structure for the gas cylinders, and the gas cylinders cannot be fixed to prevent shaking during transportation or filling. Once a gas cylinder shakes, it is very easy to affect the stability of other gas cylinders around it, thereby affecting the filling of the gas cylinder and even causing collisions to cause external damage to the gas cylinder. Therefore, a gas filling protection device is proposed. Utility Model Content
[0004] The purpose of the utility model is to provide a gas filling protection device to solve the problem that the existing gas cylinder rack lacks a fixing structure for the gas cylinder, which causes a gas cylinder to shake during transportation or filling and easily affects the stability of other surrounding gas cylinders.

[0006] A gas filling protection device comprises a base plate, wherein four vertical rods are fixedly installed on the upper surface of the base plate, a cross rod is fixedly installed between every two adjacent vertical rods, and a connecting rod is fixedly installed between every two adjacent vertical rods. A square plate is arranged above the base plate, and a plurality of square holes distributed in a rectangular array are opened on the upper surface of the square plate, and a fixed cover is arranged inside each square hole. The fixed cover is in the shape of an internal hollow frustum which is narrow at the top and wide at the bottom. Two fixing rods are fixedly installed on the outer wall surface of each fixing cover, and one end of each fixing rod away from the adjacent fixed cover is fixedly connected to the inner wall surface of the corresponding square hole. A sliding groove is opened on the inner wall surface of each connecting rod, and a sliding rod is movably installed inside each sliding groove. A square frame is sleeved on each sliding rod, and the four square frames are respectively located below the four connecting rods. A first threaded hole is opened on the two side walls of each square frame, and a first bolt is threadedly connected to the inside of each first threaded hole.
[0007] Furthermore, a cross is arranged above the square plate, and the cross is fixedly connected to the four square frames respectively.
[0008] Furthermore, a limit block is fixedly installed on the top end of each sliding rod.
[0009] Furthermore, a placement groove is provided on the upper surface of the base plate corresponding to the position of each fixing cover.
[0010] Furthermore, a rectangular plate is provided on the upper surface of the base plate, and a circular hole is opened on the lower surface of the rectangular plate corresponding to the position of each placement slot, and two mounting rods are fixedly installed at the edge of each circular hole on the upper surface of the rectangular plate, and a first arc plate is fixedly installed on the side where two mounting rods corresponding to the edge of each circular hole are close to each other, and a second arc plate is provided on the side of each first arc plate away from the adjacent mounting rod, and each first arc plate is fixedly connected to the adjacent second arc plate by three springs.
[0011] Furthermore, four second threaded holes are opened on the upper surface of the rectangular plate, and a threaded groove is opened on the upper surface of the bottom plate corresponding to the position of each second threaded hole, the inside of each second threaded hole is threadedly connected with a second bolt, and the bottom end of each second bolt is threadedly connected to the inside of an adjacent threaded groove.

It should be noted that before inflation, the staff first arranges the gas cylinders in a rectangular array on the upper surface of the bottom plate 1. At this time, a gas cylinder is placed under each fixed cover 7, and then the square plate 5 is moved downward so that each fixed cover 7 is sleeved on the corresponding gas cylinder below, and the position of each gas cylinder is fixed by the fixed cover 7. At the same time, each square frame 11 is moved up to fit with the upper connecting rod 4, and then the two first bolts 13 on each square frame 11 are rotated respectively to fix the position of each square frame 11. Due to the restrictions of the four square frames 11, each sliding rod 10 cannot slide upward inside the corresponding slide groove 9, so that the position of the square plate 5 can be limited to ensure the fixing effect of the gas cylinder, and the stability of the gas cylinder during inflation or transportation can be ensured, and the gas cylinder can be prevented from tipping over or colliding with each other to cause damage to the gas cylinder.
[0023] like Figure 1 , Figure 2 As shown, a cross 14 is provided above the square plate 5 , and the cross 14 is fixedly connected to the four square frames 11 . It should be noted that the four square frames 11 are connected by the cross 14 , so that the four square frames 11 can move up and down synchronously.
[0024] like Figure 1 As shown, a limit block 15 is fixedly installed on the top of each slide bar 10. It should be noted that when the slide bar 10 moves downward, it will drive the limit block 15 connected to it to move downward.

A second bolt 25 is threadedly connected to the inside of each second threaded hole 23, and the bottom end of each second bolt 25 is threadedly connected to the inside of an adjacent threaded groove 24. It should be noted that if there is no need to fix the bottom of the gas cylinder, each second bolt 25 can be rotated to disengage from the corresponding second threaded hole 23 and the inside of the threaded groove 24, and the rectangular plate 17 can be removed from the upper surface of the base plate 1.
[0028] In summary:
[0029] Before inflation, the staff first arranges the gas cylinders in a rectangular array on the upper surface of the base plate 1. At this time, there are gas cylinders under each fixed cover 7. Then the square plate 5 is moved downward so that each fixed cover 7 is sleeved on the corresponding gas cylinder below. The position of each gas cylinder is fixed by the fixed cover 7. At the same time, each square frame 11 is moved up to fit with the upper connecting rod 4. Then the two first bolts 13 on each square frame 11 are rotated respectively to fix the position of each square frame 11. Due to the restrictions of the four square frames 11, each sliding rod 10 cannot slide upward inside the corresponding sliding groove 9, so that the position of the square plate 5 can be limited to ensure the fixing effect of the gas cylinder, and the stability of the gas cylinder during inflation or transportation can be guaranteed to avoid the gas cylinder from tipping over or collision between gas cylinders to cause damage to the gas cylinder.
