DETAILED DESCRIPTION

[0029] The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0030] As attached Figure 1-5 As shown, a retractable hanging bracket for a fire extinguisher comprises a supporting bottom plate 11, a hanging vertical plate 12, and a fire extinguisher fixing buckle 13 arranged on the hanging vertical plate 12, and also comprises a fixing plate unit 1 which is respectively arranged on two side surfaces of the hanging vertical plate 12 together with the fire extinguisher fixing buckle 13, and a transverse retractable plate unit 2 which is plugged into the fixing plate unit 1 and is used for transversely clamping the guardrail a.

[0031] In this embodiment, the fire extinguisher fixing buckle 13 and the fixing plate unit 1 are respectively installed on both sides of the hanging vertical plate 12. The fire extinguisher fixing buckle 13 is arranged near the side end of the supporting base plate 11. The fire extinguisher is placed on the supporting base plate 11 through the fire extinguisher fixing buckle 13. When in use, the transverse telescopic plate unit 2 is adjusted to adapt to the guardrail a of different specifications.

[0032] In addition, the function of the fixed plate unit 1 is to facilitate the installation of the transverse telescopic plate unit 2, so that the fire extinguisher can be hung on the guardrail a more stably through the fixed plate unit 1 and the transverse telescopic plate unit 2.

[0033] Finally, the transverse telescopic plate unit 2 can move relative to the suspension vertical plate 12, and by adjusting the distance between the transverse telescopic plate unit 2 and the suspension vertical plate 12, the telescopic suspension bracket for the fire extinguisher can be hung on guardrails of different diameters, with a stable structure and easy use.

[0034] The fixed plate unit 1 includes a fixed plate 101 disposed on the hanging vertical plate 12 , and a hollow horizontal plate 102 disposed on the fixed plate 101 .

[0035] In this embodiment, the fixing plate 101 is arranged on the hanging vertical plate 12, and the hollow horizontal plate 102 is used to plug the horizontal telescopic plate unit 2, and the hollow horizontal plate 102 is in contact with the upper surface of the guardrail a.

[0036] The transversely extendable plate unit 2 includes an L-shaped adapter plate 201 and an insertion rod 202 disposed on the L-shaped adapter plate 201 and used for plugging the hollow transverse plate 102 .

[0037] In this embodiment, the insertion rod 202 is inserted into the hollow horizontal plate 102, and the L-shaped adapter plate 201 is used to clamp the side of the guardrail a, so that the retractable hanging bracket for the fire extinguisher can be firmly hung on the guardrail a. By adjusting the length of the insertion rod 202 inserted into the hollow horizontal plate 102, the distance between the L-shaped adapter plate 201 and the fixed plate 101 is adjusted to adapt to guardrails a of different specifications.

[0038] The transversely telescopic plate unit 2 is provided with a lifting base plate unit 3 for vertically clamping the guardrail a.

[0039] In this embodiment, the function of the lifting base unit 3 is to make the retractable suspension bracket for the fire extinguisher more firmly suspended. If there is no lifting base unit 3, the lower end of the retractable suspension bracket for the fire extinguisher lacks a clamping setting and is easy to be directly taken away or fall under force. The lifting base unit 3 allows the retractable suspension bracket for the fire extinguisher to cover the guardrail a.

[0040] The lifting base unit 3 includes a screw hole block 301 and an anti-slip plate 302 disposed on the screw hole block 301 and used for clamping the guardrail a.

[0041] In this embodiment, the screw hole block 301 is arranged on the L-shaped adapter plate 201 or the extended adjustment plate 203, and is used to connect the anti-slip plate 302. The function of the anti-slip plate 302 is to clamp the guardrail a. The distance from the anti-slip plate 302 to the fixed plate 101 is preferably 5cm-10cm.

[0042] The transverse telescopic plate unit 2 also includes an extended adjustment plate 203 arranged on the lower end of the L-shaped adapter plate 201, a threaded vertical rod 204 arranged on the extended adjustment plate 203 and used to sleeve the screw hole block 301, and a movable groove 205 arranged on the extended adjustment plate 203 for the screw hole block 301 to move up and down.

[0043] In this embodiment, the extension adjustment plate 203 is used to increase the contact area with the guardrail a, increase the force area, make the force more reasonable, and facilitate the connection with the anti-slip plate 302. The threaded vertical rod 204 is inserted into the extension adjustment plate 203. The movable groove 205 is used to install the threaded vertical rod 204, which is convenient for the movement of the screw hole block 301. The screw hole block 301 is sleeved on the threaded vertical rod 204. When the threaded vertical rod 204 is rotated, the screw hole block 301 moves up and down relative to the screw hole block 301. The outer ring of the screw hole block 301 can be provided with a ball bearing that does not limit its own rotational freedom, which is convenient for driving the anti-slip plate 302 to move up and down. When in use, the extension adjustment plate 203 fits with the side of the guardrail a, and the anti-slip plate 302 is adjusted by rotating the threaded vertical rod 204 so that the anti-slip plate 302 fits with the bottom surface of the guardrail a, making the structure stable and firm.

[0044] The transversely extendable plate unit 2 further includes a rotating shaft 206 which is arranged on the extension adjustment plate 203 and is used to connect the L-shaped adapter plate 201 .

[0045] In this embodiment, when the distance between the anti-slip plate 302 and the hanging vertical plate 12 is relatively close, after adjusting the L-shaped adapter plate 201, it is still easy to be blocked by the anti-slip plate 302 when hanging, which makes it inconvenient for the retractable hanging bracket for the fire extinguisher to be hung on the guardrail a. Therefore, the rotating shaft 206 is provided, and the rotating shaft 206 is rotated before hanging so that the anti-slip plate 302 is temporarily located away from the side end of the hanging vertical plate 12. After hanging, the anti-slip plate 302 is turned back to the lower end surface of the guardrail a, and then the threaded vertical rod 204 is adjusted so that the anti-slip plate 302 is in contact with the lower bottom surface of the guardrail a.

[0046] The fixing plate unit 1 further includes a locking screw 103 which is arranged on the hollow transverse plate 102 and is used to fix the insertion rod 202 .

[0047] In this embodiment, the locking screw 103 serves to make the extension length of the insertion rod 202 more precise and less prone to sliding.

[0048] The lifting base plate unit 3 further includes a rubber pad 303 arranged on the upper end surface of the anti-slip plate 302 .

[0049] In this embodiment, the function of the rubber pad 303 is to make the anti-slip plate 302 fit better with the guardrail a, and to further protect the guardrail a so as not to scratch the guardrail a due to hanging problems. At the same time, when adjusting the anti-slip plate 302, the rubber pad 303 can serve as a reminder, indicating that the anti-slip plate 302 and the guardrail a are in contact.

[0050] The fixed plate unit 1 further includes an anti-slip pad 104 disposed on the lower surface of the hollow transverse plate 102 .

[0051] In this embodiment, the function of the anti-slip pad 104 is to prevent the retractable suspension bracket for the fire extinguisher from sliding left and right due to external force during use, causing adverse effects, so that the installation of the retractable suspension bracket for the fire extinguisher is more stable, and the guardrail a can also be protected at the same time.

[0052] The above is a detailed description of the implementation of the utility model in conjunction with the accompanying drawings, but the utility model is not limited to the above implementation. Various modifications can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the utility model. These are all non-creative modifications and are protected by patent law as long as they are within the scope of the claims of the utility model.
