Description

Technical Field

[0001] This utility model relates to the field of fire hydrant technology, specifically a fire hydrant valve handle switch tool. Background Technology

[0002] Firefighting plays a crucial role in protecting lives and property and maintaining social stability. Fire hydrants, as one of the most important firefighting facilities, directly affect the effectiveness of fire suppression efforts through their rapid and effective opening and closing. During firefighting operations, the operation of fire hydrant valves is a fundamental yet extremely important step.

[0003] In practical applications, fire hydrants are typically installed inside fire hydrant wells. Due to geographical conditions, building planning, and other factors, the depth of fire hydrants varies significantly across different regions. However, current tools used for operating fire hydrants inside these wells have obvious drawbacks. Existing fire hydrant operating tools are often of fixed length or have extremely limited adjustable range, making it difficult to adjust them flexibly and effectively according to the actual depth of the fire hydrant well.

[0004] When facing deep fire hydrant wells, standard-length tools cannot reach the valves, forcing firefighters to spend extra time finding suitable tools or using makeshift solutions, significantly delaying the optimal time for firefighting. Conversely, if the fire hydrant well is shallow, excessively long tools are not only inconvenient to operate but may also damage the hydrant and surrounding facilities due to collisions during operation. This mismatch between tool length and fire hydrant depth severely restricts the efficiency and safety of firefighting operations, increasing the potential losses caused by fire. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a fire hydrant valve handle switch tool, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fire hydrant valve handle switch tool, comprising a sleeve, an inner rod, a handle body, fasteners, and a switch sleeve;

[0007] The inner rod is slidably connected inside the sleeve, the handle body is laterally disposed through the top of the sleeve, the fastener is threadedly connected to the outside of the sleeve, and one end of the fastener penetrates and extends into the inside of the sleeve and abuts against the inner rod.

[0008] The switch sleeve is detachably mounted on the bottom end of the inner rod.

[0009] Furthermore, the inner circumferential wall of the sleeve and the cross-section of the upper end of the inner rod are both square.

[0010] Furthermore, the inner rod moves up and down along the length of the sleeve.

[0011] Furthermore, the bottom end of the switch sleeve is recessed upward to form a square hole, which is used to fit onto the outside of the fire hydrant valve switch.

[0012] Furthermore, a mounting plate is provided at the bottom of the inner rod, and two bolts are vertically installed on the left and right sides of the upper surface of the switch sleeve, with the tops of the two bolts penetrating and extending to the top of the mounting plate.

[0013] Both bolts are threaded with nuts on their outer sides, and the nuts are in contact with the upper end face of the mounting plate.

[0014] Furthermore, two through holes are provided inside the mounting plate, each for a bolt to pass through.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] 1. This fire hydrant valve handle switch tool has an inner rod that slides within the sleeve. The extension length of the inner rod can be adjusted by loosening or tightening the fasteners, allowing it to flexibly adapt to fire shafts of different depths. When facing a deeper fire shaft, the tool can be extended to reach the valve, while when the fire shaft is shallower, the tool can be shortened to avoid inconvenience in operation and collision damage to surrounding facilities, greatly improving the efficiency of fire fighting operations and reducing fire losses.

[0017] 2. This fire hydrant valve handle switch tool features a switch sleeve that is detachably mounted on the bottom of the inner rod using bolts and nuts. This allows for easy replacement of the appropriate sleeve for different types of fire hydrant valves. When encountering valves of different specifications, it is not necessary to replace the entire tool; only the corresponding sleeve needs to be replaced, reducing usage costs and improving the tool's versatility and applicability.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 In this embodiment, a fire hydrant valve handle switch tool is provided, the length of which can be adjusted according to different well depths, and the switch sleeve 5 can be easily disassembled and replaced.

[0025] Specifically, it includes a sleeve 1, an inner rod 2, a handle body 3, a fastener 4, and a switch head 5; the inner rod 2 is slidably connected inside the sleeve 1, the handle body 3 is horizontally inserted through the top of the sleeve 1, the fastener 4 is threadedly connected to the outside of the sleeve 1, and one end of the fastener 4 penetrates through and extends into the inside of the sleeve 1 and abuts against the inner rod 2; the switch head 5 is detachably installed at the bottom end of the inner rod 2.

[0026] In actual use, first loosen the fastener handle switch 4. The fastener handle switch 4 is threaded to the outside of the sleeve handle switch 1, with one end penetrating and extending into the inside of the sleeve handle switch 1. After loosening, the inner rod handle switch 2 can slide freely inside the sleeve handle switch 1. The operator can pull the inner rod handle switch 2 up or down according to the actual depth of the fire well. After adjusting the inner rod handle switch 2 to the appropriate length, tighten the fastener handle switch 4 again so that one end of it tightly abuts against the inner rod handle switch 2, thereby fixing the position of the inner rod handle switch 2 and ensuring that the inner rod handle switch 2 will not slide arbitrarily during subsequent operations.

[0027] Furthermore, in order to ensure that the inner rod 2 can be effectively rotated when the sleeve 1 is rotated, the inner peripheral wall of the sleeve 1 and the upper cross-section of the inner rod 2 are preferably square in this embodiment, so that the movement trajectory of the inner rod 2 is to move up and down along the length of the sleeve 1.

[0028] Furthermore, the bottom end of the switch sleeve 5 is recessed upward to form a square hole, which is used to fit on the outside of the fire hydrant valve switch.

[0029] In actual use, the square hole formed by the inward concavity of the bottom of the switch sleeve handle switch 5 is fitted onto the outside of the fire hydrant valve switch. Since the square hole is compatible with the shape of the fire hydrant valve switch, it can fit tightly and provide sufficient friction to turn the valve. The firefighter holds the handle body handle switch 3 and drives the sleeve handle switch 1, as well as the inner rod handle switch 2 and the switch sleeve handle switch 5 connected to it to rotate, thereby realizing the opening or closing operation of the fire hydrant valve.

[0030] In detail, to facilitate the replacement of the switch sleeve 5, a mounting plate 6 is provided at the bottom of the inner rod 2 in this embodiment. Two bolts 7 are vertically installed on the left and right sides of the upper end face of the switch sleeve 5. The tops of the two bolts 7 penetrate and extend to the top of the mounting plate 6. Nuts 8 are threaded to the outside of the two bolts 7. The nuts 8 fit against the upper end face of the mounting plate 6. Two through holes are opened inside the mounting plate 6 for the two bolts 7 to pass through.

[0031] In actual use, if the switch sleeve handle switch 5 is found to be worn or unsuitable, it can be easily replaced. Simply unscrew the nut handle switch 8, pull the bolt handle switch 7 out of the through hole on the mounting plate handle switch 6, and you can remove the old switch sleeve handle switch 5. Then replace it with the new switch sleeve handle switch 5, and tighten the nut handle switch 8 according to the above installation steps to fix the switch.

[0032] The working principle of the above embodiments is as follows:

[0033] (1) By utilizing the sliding connection of the inner rod handle switch 2 within the sleeve handle switch 1 and the fastening action of the fastener handle switch 4, the overall length of the tool can be adjusted to adapt to fire wells of different depths. Then, through the matching connection between the switch sleeve handle switch 5 and the fire hydrant valve switch, the rotation of the handle body handle switch 3 drives the switch sleeve handle switch 5 to rotate, thereby realizing the opening and closing operation of the fire hydrant valve. Throughout the process, the detachable switch sleeve handle switch 5 is designed to be easy to replace according to actual needs, improving the applicability of the tool.

[0034] (2) If the switch sleeve handle switch 5 is found to be worn or unusable, simply unscrew the nut handle switch 8, pull the bolt handle switch 7 out of the through hole on the mounting plate handle switch 6, remove the old switch sleeve handle switch 5, replace it with the new switch sleeve handle switch 5, and then tighten the nut handle switch 8 according to the above installation steps to fix the handle switch.
