Detailed Description

In order to make the structural form and advantages of the folding detachable workbench described in the patent of the utility model more clear, the structural form of the novel workbench will be clearly and completely described below with reference to the accompanying drawings.

Referring to fig. 1 and 3, the whole structure of the utility model comprises a workbench bottom plate 1, a workbench upper guard rail 2, a fixed pulley 3, a supporting rod 4, a safety buckle 5, a sliding clamp 7, a telescopic guard rail 8, an outer telescopic rod 9, an inner telescopic rod 11 and the like.

Referring to fig. 1 and 2, the structure of the folded workbench of the utility model is shown. The guardrail 2 is rectangular frame on the workstation, and the below of four corners is equipped with perpendicular bracing piece, and workstation bottom plate 1 is the rectangular plate the same with guardrail 2 overall dimension on the workstation, and the short one side of workstation bottom plate 1 is equipped with folding board 10, passes through hinge connection between folding board 10 and the workstation bottom plate 1, makes things convenient for firemen business turn over and personnel to dredge the commentaries on classics. The four support rods 4 are respectively arranged at the four corners of the workbench upper guardrail 2 and the workbench bottom plate 1. The support bar 4 is composed of an upper support bar and a lower support bar with the same length, the upper end of the upper support bar is connected with the lower end of the vertical support bar, the lower end of the upper support bar is connected with the upper part of the outer end of the telescopic guardrail 8, the upper end of the lower support bar is connected with the lower part of the outer end of the telescopic guardrail 8, the lower end of the lower support bar is connected with the workbench bottom plate 1, and all bars are connected through connecting shafts 6. The outer telescopic rod 9, the telescopic guardrail 8 sleeved and telescopic at one side of the outer telescopic rod, the telescopic inner telescopic rod 11 sleeved and telescopic at the other side of the outer telescopic rod and the telescopic guardrail 8 form telescopic support rods, and two telescopic support rods are respectively connected between the folding ends of the middle of the two long support rods 4. The telescopic guardrail 8 on one side and the inner telescopic rod 11 on the other side as well as the telescopic guardrail 8 are contracted into the outer telescopic rod 9, and the upper support rods and the lower support rods on the two sides can be driven to be folded into a horizontal state, so that the telescopic guardrail is in a folded state, occupies small space and is convenient for firefighters to carry. The long both sides of workstation bottom plate 1 all are equipped with slidable track for install slip formula clamp 7, slip formula clamp 7 has four, and the track of both sides is installed two respectively. The sliding range of the sliding type clamp 7 is large, so the workbench can be installed on different herringbone ladders, and the application range is wider.

Referring to fig. 3 and 4, the working table of the present utility model is shown in a structure after being unfolded. The fireman spreads the workbench by pulling the telescopic rod 11, inserts the pin shaft 12 into the positioning hole of the telescopic rod after spreading, and fixes the workbench guardrail, thereby obtaining the structure diagram of the unfolded workbench shown in fig. 3.

Referring to fig. 5 and 6, the structure of the workbench of the utility model after being mounted on the herringbone ladder is shown. The fixed pulleys 3 are symmetrically arranged in the middle of the guardrail 2 on the workbench. The bottom of the vertical support rod is lower than the bottom of the fixed pulley 3, so that the workbench bottom plate 1 can be folded regularly without touching the fixed pulley 3 after being folded. The double ladder behind the installation workstation can provide safe and stable working space for the fireman. The fixed pulley 3 is used for hanging and lifting broken equipment, so that 'people are separated' in the step climbing process of a firefighter can be realized, hands are liberated to the maximum extent, and the operation safety is improved. After the workbench is fixed with the fire ladder, a fire fighter can climb on the workbench by rotating the folding plate 10 and then put down the folding plate, and the structure is convenient for the fire fighter to get in and out. The guard rail 2 on the workbench is provided with a plurality of safety buckles 5, and a firefighter can hook the safety hook on the firefighter uniform to ensure the safety of firefighting operation.

The upper guard rail 2, the bottom plate 1, the support rod 4, the telescopic guard rail 8, the outer telescopic rod 9 and the inner telescopic rod 11 are all made of aluminum alloy, and the structure is light and reliable and is convenient to carry.

When the fire fighting equipment is used, a fire fighter puts the workbench on a fire fighting herringbone ladder to be installed, pushes the lower sliding clamp 7 to a proper position for locking, and fixes the workbench and the herringbone ladder together. Compared with the traditional positioning mounting holes or mounting shafts, the structure is higher in applicability and can adapt to different herringbone ladder structures. After the installation is completed, the firefighter expands the workbench by pulling the telescopic rod 11, then fixes the telescopic rod by the bolt 12, and the workbench is built.

In conclusion, the workbench is reasonable in structural design, and can provide a safe and stable working space for firefighters, so that firefighters can safely and efficiently complete firefighting rescue work; the workbench structure can be installed on different herringbone ladders, has strong practicality, is provided with a fixed pulley structure, can greatly reduce safety risks, and has strong innovation.
