[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] Example 1

[0040] like Figure 1-2 As shown, the present utility model discloses a wheeled fire extinguisher, comprising: a traveling frame 10 having a second traveling wheel 101;

[0041] The limiting opening 20 is provided on the traveling frame 10; and the cylinder 3 is provided on the traveling frame 10;

[0042] The supporting legs of the steel cylinder 3 can pass through the limiting opening 20 and fix the steel cylinder 3 on the traveling frame 10 through the protective body 4 .

[0043] In the present invention, the steel cylinder 3 includes a bottle body 30 and a chamber provided in the bottle body 30. A plurality of support legs 31 are welded to the bottom of the bottle body 30. Each support leg 31 is provided with a first walking wheel 32. The protective body is detachably connected to the support legs 31.

[0044] In this embodiment: the protection body 4 includes:

[0045] The body 40 has a storage cavity 41 for accommodating the support legs 31;

[0046] Internal thread 42, provided on the inner wall of the receiving cavity 41;

[0047] The outer wall of the support leg 31 is provided with an external thread 31 a adapted to the internal thread 42 .

[0048] In this embodiment, the first running wheel 32 is provided at the end of the support leg 31 , and the first running wheel 32 is rotatably connected to the support leg 31 .

[0049] In this embodiment, a dovetail block 43 is integrally formed on the main body 40 , and an inclined discharge surface 44 is provided on the main body 40 .

[0050] In this embodiment, a non-slip pad 40a is fixedly connected to a side of the main body 40 away from the bottle body.

[0051] In this embodiment, the walking frame 10 includes:

[0052] The support plate 100 is provided with the second traveling wheel 101;

[0053] A dovetail groove 102 is formed at the bottom of the support plate 100 and is adapted to fit the dovetail block;

[0054] When the main body is installed in the dovetail groove 101 , an inclined discharge surface 44 is formed on one side of the support plate 100 .

[0055] refer to Figure 1-2 , the principle of this embodiment is:

[0056] When installing the steel cylinder, at least two protective bodies are installed on the traveling frame through dovetail blocks, and the steel cylinder is pushed to move through the first traveling wheel until it moves to the support plate, and the supporting legs are aligned with the various limiting openings on the support plate, and the supporting legs are passed through the supporting plate through the limiting openings to complete the limiting. Then, each protective body is installed one by one from the bottom of the support plate to the supporting legs (that is, by aligning the supporting legs with the receiving cavity on the main body, and completing the installation of the protective body by matching the external thread on the supporting leg with the internal thread in the receiving cavity). After the installation is completed, when the supporting plate is stationary, it is supported by the protective bodies. When moving, the supporting plate is tilted with the ground through the armrest of the traveling frame, and the protective bodies are separated from the ground, thereby pushing the traveling frame to achieve the purpose of movement.

[0057] During disassembly, the protective bodies are removed one by one, and the supporting legs of the cylinder are moved away from the limit openings. The cylinder is moved by pushing and removed from the supporting plate.

[0058] Example 2 is different from Example 1 in that:

[0059] like Figure 3-4 As shown, in this embodiment, both sides of the body 40 are provided with a detachably connected plug-in structure and a plug-in slot 6; wherein the plug-in structure includes:

[0060] The plug-in block 50 is integrally formed on one side of the body 40 and can be inserted into the plug-in slot 6 at one end;

[0061] The mounting groove 51 is formed on the inner wall of both sides of the plug-in block 50, and the inner wall of the groove of the mounting groove 51 is recessed to form a movable groove 52;

[0062] The metal spring 53 is located at the notch of the mounting slot 51 and has two ends that are slidably disposed in the movable slot 52;

[0063] The limit spring 54 is disposed in the mounting groove 51, with its two ends respectively abutting against the metal spring 53 and the groove wall of the mounting groove 51;

[0064] The slot wall of the plug-in slot 6 is formed with a notch 60 (a recessed area formed on the inner wall of the plug-in slot) for the metal spring 53 to be inserted into.

[0065] refer to Figure 3-4 In order to improve the stability of the protective body in use, the protective bodies in this embodiment can be installed through the cooperation of the plug-in structure and the plug-in slot.

[0066] That is, when the plug-in block enters the plug-in slot, the metal spring presses the limit spring downward, causing the metal spring to enter the plug-in slot, and when the metal spring moves to the notch, the metal spring is stuck in the notch to complete the fixation between the protective bodies.

[0067] In this embodiment, after the multiple protective bodies are assembled with each other and fixed with the dovetail groove, the stable use of the unloading surface can be improved, and the stability of the installation and unloading of the cylinder can be guaranteed.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
