Description

Technical Field

[0001] The utility model relates to the technical field of dry powder fire extinguisher trolleys, and more particularly to a dry powder fire extinguisher trolley. Background Art

[0002] In existing technologies, dry powder fire extinguisher trolleys often need to be fixed and adjusted according to the size of the fire extinguishers when handling different types of fire extinguishers. However, existing trolley equipment has certain limitations in terms of adjustment, which directly affects the user experience and operating efficiency.

[0003] Because different models of dry powder fire extinguishers can vary significantly in size and weight, existing trolleys often lack sufficient flexibility in their designs. This means that when users need to switch to different fire extinguisher models, the trolleys cannot easily adapt to these changes. Fixed size adjustment mechanisms require users to manually adjust the trolley's internal structures, such as the bracket, tray, or fixing straps, to accommodate the new fire extinguisher size. This adjustment process is not only time-consuming but may also require specific tools, increasing operational complexity and reducing the convenience and efficiency of the equipment.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the present invention provides a dry powder fire extinguisher trolley with the following features:

[0017] Beneficial effects:

[0018] 1. The design of the fixing mechanism enables the dry powder fire extinguisher trolley to flexibly adapt to fire extinguishers of different sizes. Through the coordination of the bracket, fixing rod, pressing sleeve, threaded sleeve, external spring, fixing sleeve, insertion rod, push rod, friction spring and other components, the operator can select the appropriate positioning hole according to the size of the fire extinguisher, and through the connection between the insertion rod and the fixing sleeve, and the interaction between the push rod and the friction spring, the fire extinguisher is stably fixed.

[0019] 2. The clamping mechanism realizes precise control of the position between the fixing rod and the fixing sleeve through the setting of the limiting sleeve. When the limiting sleeve slides downward, the push rod and the limiting sleeve form a spiral connection, thereby ensuring the fixed state of the fixing rod and the pressing sleeve. This design not only improves the stability of the fixation, but also enables the operator to complete the fixing process quickly and accurately.

[0020] 3. The positioning mechanism realizes the precise control of the position between the insertion rod and the positioning block through the cooperation of the positioning rod, the top block and the middle hole. When the positioning rod is inserted into the middle hole and threadedly connected to the top block, it can ensure that the relative position between the insertion rod and the positioning block remains unchanged, thereby ensuring the fixed stability of the fire extinguisher.

[0031] In this embodiment, when fire extinguishers of different sizes need to be fixed, different positioning holes 11 are first selected, and then the insertion rods 8 on the two push rods 9 are respectively inserted into the fixing sleeve 7, and then the pressing sleeve 4 is fixed, and then the fire extinguisher is fixed by the pressing sleeve 4 and the bracket 2. Since there is a friction spring 10 on the push rod 9, the friction spring 10 will resist in the lateral hole 12, so that the friction spring 10 has a certain friction force, and then the insertion rod 8 is inserted into the fixing sleeve 7, and when the fixing rod 3 is fitted on the fixing sleeve 7, the limiting sleeve 13 is slid downward so that multiple push rods 9 resist in the limiting sleeve 13.

At this time, multiple push rods 9 and the spiral groove 14 form a spiral connection, and due to the fixed connection between the two fixing rods 3 and the pressing sleeve 4, the fixing rod 3 and the pressing sleeve 4 are in a fixed state, thereby ensuring the fixation of the fire extinguisher, and through the action of the internal spring 18 and the external spring 6, it is ensured that the fixing rod 3 can bend to a certain extent, thereby ensuring adaptability.
