DETAILED DESCRIPTION

[0018] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] The present application embodiment discloses a fixing device for a steel cylinder, referring to Figure 1 , Figure 2 and Figure 3 , including a mounting seat 1, a mounting plate 11 is vertically bolted to the mounting seat 1, and a plurality of parallel mounting frames 3 are arranged on the mounting plate 11 at intervals in the vertical direction. The mounting frame 3 includes a first mounting rod 31, a second mounting rod 32 and two rotating shaft pull rods 33, the rotating shaft pull rods 33 are threaded rods, the first mounting rod 31 is horizontally bolted to the mounting plate 11, and first threaded holes with sizes matching the rotating shaft pull rods 33 are provided at both ends of the first mounting rod 31, and the two rotating shaft pull rods 33 are perpendicular to the mounting plate 11 and are respectively threaded in the two first threaded holes. First through holes for the rotating shaft pull rods 33 to pass through are provided at both ends of the second mounting rod 32, and the ends of the two rotating shaft pull rods 33 away from the first mounting rod 31 respectively pass through the corresponding first through holes, so that the second mounting rod 32 can move axially along the rotating shaft pull rod 33. The first mounting rod 31 , the second mounting rod 32 and the two rotating shaft pull rods 33 together form an installation space 34 for placing the cylinder, and the two rotating shaft pull rods 33 are both equipped with a first limiter 4 for limiting the movement of the second mounting rod 32 relative to itself.

[0020] In the embodiment of the present application, the staff places the fire extinguisher cylinder in the installation space 34, and then moves the second installation rod 32 so that the first installation rod 31 and the second installation rod 32 abut against the two sides of the cylinder. Then, only the first limiter 4 is needed to limit the movement of the second installation rod 32 relative to the rotating shaft pull rod 33, thereby achieving the effect of fixing the cylinder. In this way, it can be used to install cylinders of various models and sizes. A plurality of bolt reserved holes are provided on the mounting plate 11, and the fixing device of the present application can be installed on a wall or the ground as a whole with the help of bolts. Compared with the fire extinguisher bracket in the comparative document, the cylinder fixing device of the present application can not only be used to fix cylinders of various models, but also has the effect of convenient operation.

[0021] Specifically, the first limiting member 4 includes two locking nuts 41 , which are respectively threadedly connected to the rotating shaft pull rod 33 , and the locking nuts 41 are located on a side of the second mounting rod 32 away from the first mounting rod 31 .

[0022] When the first mounting rod 31 and the second mounting rod 32 abut against both sides of the cylinder, the locking nut 41 is rotated to abut against a side of the second mounting rod 32 away from the first mounting rod 31, thereby limiting the movement of the second mounting rod 32.

[0023] In order to prevent the first mounting rod 31 and the second mounting rod 32 from causing wear to the side wall of the steel cylinder, the first mounting rod 31 and the second mounting rod 32 are provided with a flexible layer 5 on one side thereof that is used to contact the steel cylinder. The flexible layer 5 can be made of a flexible material such as rubber.

[0024] Furthermore, a second limiting member 6 for limiting the rotation of the locking nut 41 is installed on the rotating shaft tie rod 33. The second limiting member 6 includes a split pin 61, and the locking nut 41 adopts a hexagonal slotted nut. The rotating shaft tie rod 33 is provided with a plurality of limiting holes 331 for inserting the split pin 61 along its own axial direction. The split pin 61 passes through the notch of the hexagonal slotted nut and then passes through the corresponding limiting hole 331, thereby limiting the rotation of the hexagonal slotted nut relative to the rotating shaft tie rod 33. The stability of the cylinder in the installation frame 3 is further improved.

[0025] In the embodiment of the present application, a plurality of washers 42 may be installed between the hexagonal slotted nut and the second mounting rod 32 to adjust the position of the hexagonal slotted nut on the shaft pull rod 33 , thereby ensuring that the notch of the hexagonal slotted nut can be aligned with the limiting hole 331 .

[0026] Furthermore, a fixing plate 7 is connected between the rotating shaft rods 33 on the same side of the multiple mounting frames 3, and a second through hole for the rotating shaft rod 33 to pass through is provided on the fixing plate 7, and two rotating shaft rods 33 pass through the corresponding second through holes respectively. Clamps 8 for abutting against the outer wall of the cylinder are provided horizontally and oppositely on the fixing plates 7 on both sides, and a driving member 9 for driving the clamps 8 to move is installed on the fixing plates 7. The driving member 9 includes a screw 91, and a second threaded hole with a size matching that of the screw 91 is provided on the fixing plate 7, and the screw 91 is threadedly connected in the second threaded hole, and one end of the screw 91 is rotatably connected to the clamp 8.

[0027] In the embodiment of the present application, after the locking nut 41 is rotated to ensure that the first mounting rod 31 and the second mounting rod 32 are pressed against the two side walls of the steel cylinder, the screw rods 91 on both sides can be rotated to drive the two clamping plates 8 to clamp the other two sides of the steel cylinder together, further improving the stability of the steel cylinder in the installation frame 3. Since the rotating shaft rod 33 passes through the corresponding second through hole, the fixing plate 7 can move axially along the corresponding rotating shaft rod 33, so that the clamping plates 8 can cooperate to clamp steel cylinders of different models and sizes.

[0028] Furthermore, the clamping plate 8 is an arc-shaped elastic sheet. When the screw 91 drives the elastic sheet to abut against the side wall of the steel cylinder, the elastic sheet can be deformed so that its inner arc surface can fit the outer wall of the steel cylinder, further improving the fixing effect on the steel cylinder. The elastic sheet can be a metal spring sheet or a spring sheet of other materials.

[0029] The implementation principle of the steel cylinder fixing device of the present application embodiment is as follows: the staff places the fire extinguisher steel cylinder in the installation space 34, then moves the second installation rod 32 so that the first installation rod 31 and the second installation rod 32 abut against the two sides of the steel cylinder, and then only the first limiter 4 is needed to limit the movement of the second installation rod 32 relative to the rotating shaft pull rod 33, thereby achieving the effect of fixing the steel cylinder. Compared with the fire extinguisher bracket in the comparative document, the steel cylinder fixing device of the present application can not only be used to fix various types of steel cylinders, but also has the effect of convenient operation.
