Description

Technical Field

[0001] This solution falls under the field of maintenance tools, specifically involving maintenance equipment for a fire safety cabinet. Background Technology

[0002] Fire safety cabinets are essential facilities used to store and protect fire-fighting equipment, such as fire extinguishers and fire hoses. Various maintenance tools are required for the routine inspection of fire safety cabinets.

[0003] A search revealed a utility model patent with authorization announcement number CN222467946U, which discloses a maintenance device for a fire safety cabinet. This device includes a mounting tube with a cross-shaped groove on one side. Symmetrically fixed protruding rings are mounted on the surface of the mounting tube near the cross-shaped groove. Rotating slots are symmetrically arranged on the surface of the mounting tube near the protruding rings and on the side of the rubber pad closest to the protruding rings. This maintenance device for the fire safety cabinet utilizes a spring, mounting bracket, double-ended nuts, and rotating rings to pull the mounting bracket, causing the double-ended nuts to move away from the mounting tube.

[0004] When inspecting fire safety cabinets, different screwdrivers are needed to tighten different types of bolts, which is not only inconvenient to carry, but also takes up a lot of space in the toolbox. Utility Model Content

[0005] The purpose of this solution is to provide a maintenance device for fire safety cabinets to solve the problem that different screwdrivers are needed to tighten different types of bolts when maintaining fire safety cabinets, which is not only inconvenient to carry but also occupies a large amount of space in the toolbox.

[0006] To achieve the above objectives, this solution provides a maintenance device for a fire safety cabinet, including a handle. Two rotating shafts are mounted inside the handle via bearings. A reversing seat is fixedly connected between the two rotating shafts. A flathead screwdriver bit and a Phillips head are fixedly connected to the upper and lower ends of the reversing seat, respectively. A reversing locking mechanism is provided on the handle and below the reversing seat. Two rotating shafts are rotatably connected inside the handle. A folding frame is fixedly connected to the ends of the two rotating shafts. A locking sleeve is fixedly connected to the handle. A pin is slidably connected inside the locking sleeve, passing through the locking sleeve and engaging with the rotating shaft on the right side.

[0007] The principle of this solution is as follows: First, pull the locking pin using the pull ring to disengage it from the rotating shaft on the right side, thus releasing the restriction on the rotating shaft. Then, flip the folding frame over. Once in position, reinsert the locking pin into the rotating shaft. The entire assembly can then be rotated for use. Additionally, pulling down the slide causes it to slide along the handle, compressing the second spring. At this point, the locking pin on the slide disengages from the reversing seat, releasing the restriction on the reversing seat. Rotating the reversing seat then swaps the slotted and Phillips head screwdriver bits. After swapping, releasing the slide causes it to return to its original position under the action of the second spring, and the locking pin locks the reversing seat. This allows for the tightening of different bolt sizes without the need to carry two different screwdrivers.

[0008] The technical advantage of this solution is that by setting a handle with a reversing seat that rotates via a pivot, and fixing a flathead screwdriver bit and a Phillips head bit to the upper and lower ends of the reversing seat respectively, and then setting a matching reversing locking mechanism below the reversing seat, different types of screwdriver bits can be replaced, which is convenient for use when inspecting fire safety cabinets and eliminates the need to carry two different types of screwdrivers.

[0009] By setting a folding frame that can rotate via a pivot on the outside of the handle, the folding frame is C-shaped and has a retractable locking pin that can lock the pivot. This makes the folding frame easy to carry when folded and increases its overall length when unfolded for easy use.

[0010] Furthermore, a rubber block is fixedly connected to the horizontal part of the folding frame. This rubber block provides protection for the end of the bit.

[0011] Furthermore, a pull ring is fixedly connected to the top of the locking pin, and the pull ring and the locking pin are an integral structure. The pull ring facilitates the pulling of the locking pin.

[0012] Furthermore, a guide block is fixedly connected to the inner wall of the locking sleeve, and the guide block is slidably connected to the pin. A guide rod is fixedly connected inside the pin, and the guide rod passes through the guide block and is slidably connected to it. A spring is sleeved on the outer side of the guide rod. The guide rod, guide block, and spring provide a guiding function for the pin.

[0013] Furthermore, one end of the first spring is fixedly connected to the guide block, and the other end of the first spring is fixedly connected to the inner surface of the pin. By using the first spring, the elastic force can be applied to the locking pin.

[0014] Furthermore, the reversing locking mechanism includes a sliding column slidably connected inside the handle, a slide bracket fixedly connected to the top of the sliding column, and a locking pin fixedly connected to the top of the slide bracket. The locking pin is inserted into the reversing seat. A second spring is disposed inside the handle, one end of which is fixedly connected to the sliding column, and the other end of which is fixedly connected to the inner surface of the handle. Through the provision of the reversing locking mechanism, a locking effect is achieved when the reversing seat reverses its direction.

[0015] Furthermore, a guide strip is fixedly connected to the side of the carriage, and the guide strip passes through the handle and is slidably connected to the handle. The guide strip guides the extension and retraction of the carriage. Attached Figure Description

Detailed Implementation

[0022] The basic implementation examples are as follows: Figures 1-4The image shows a maintenance device for a fire safety cabinet, comprising a handle 1. Inside the handle 1, two rotating shafts 2 are mounted via bearings. A reversing seat 3 is fixedly connected between the two rotating shafts 2. A flathead screwdriver bit 31 and a Phillips head screwdriver bit 32 are fixedly connected to the upper and lower ends of the reversing seat 3, respectively. Two rotating shafts 5 are rotatably connected inside the handle 1. A folding frame 6 is fixedly connected to the ends of the two rotating shafts 5. A rubber block 7 is fixedly connected to the horizontal part of the folding frame 6. The rubber block 7 provides protection for the ends of the screwdriver bits. A locking sleeve 8 is fixedly connected to the handle 1. A pin 9 is slidably connected inside the locking sleeve 8, passing through the locking sleeve 8 and engaging with the right-side rotating shaft 5. A pull ring 10 is fixedly connected to the top of the pin 9, and the pull ring 10 and the pin 9 are an integral structure. The pull ring 10 facilitates the pulling of the pin 9.

[0023] like Figure 4 As shown, a guide block 11 is fixedly connected to the inner wall of the locking sleeve 8. The guide block 11 is slidably connected to the pin 9. A guide rod 12 is fixedly connected inside the pin 9. The guide rod 12 passes through the guide block 11 and is slidably connected to the guide block 11. A spring 13 is sleeved on the outer side of the guide rod 12. Through the arrangement of the guide rod 12, the guide block 11, and the spring 13, one end of the spring 13, which has a guiding effect on the pin 9, is fixedly connected to the guide block 11, and the other end of the spring 13 is fixedly connected to the inner surface of the pin 9. The spring 13 allows a spring force to be applied to the pin 9.

[0024] like Figure 1 , Figure 2 , Figure 3 As shown, a reversing locking mechanism 4 is provided on the handle 1 and below the reversing seat 3. This mechanism locks the reversing seat 3 after it has reversed its direction. The reversing locking mechanism 4 includes a sliding column 41 slidably connected inside the handle 1. A slide frame 42 is fixedly connected to the top of the sliding column 41, and a locking pin 43 is fixedly connected to the top of the slide frame 42. The locking pin 43 is inserted into the reversing seat 3. A second spring 45 is provided inside the handle 1.
