Description

Technical Field

[0001] This utility model relates to the field of fire protection agency testing technology, specifically a fire protection agency testing device for fire escape routes. Background Technology

[0002] In the field of fire protection engineering testing technology, fire lane facilities are often inspected periodically. Visual inspection involves observing the appearance of the fire protection equipment to confirm the presence of obvious damage, loosening, or detachment, such as broken fire extinguisher casings or loose sprinkler heads. Operational testing checks verify the equipment's functionality, including pressure and spray tests on fire extinguishers and alarm tests on alarm control panels. Specialized instruments and equipment are used for testing and verification, such as smoke generators to test the sensitivity of fire alarm systems and flame simulators to test the sensitivity of sprinkler systems. However, existing fire protection agency testing equipment still has certain problems in its use.

[0003] For example, a fire protection engineering testing device with publication number CN212341411U has the following technical solution: it includes a test mounting shell, and a telescopic mechanism is installed below the test mounting shell. The telescopic mechanism includes a telescopic rod, a bottom shell, a sleeve, and a nut. The top outer wall of the sleeve is provided with an external thread, and the sleeve is connected to the nut through the external thread. This fire emergency lighting testing device can extend and retract according to the corresponding length through the setting of the telescopic component, thereby realizing the rapid testing of emergency lighting at high places, avoiding the use of ladders for high-altitude testing, and greatly improving the testing efficiency of fire equipment. In addition, the overall structure of this fire emergency lighting testing device is reasonably set, with good portability and practicality, making it easy for maintenance personnel to use and carry, improving testing efficiency, and having a wide range of applications. However, existing testing devices have limited functionality and cannot be fixed when testing fixed facilities, causing inconvenience during the testing process.

[0004] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0005] To address the aforementioned issues, an innovative design was developed based on the existing testing equipment used by fire departments. Utility Model Content

[0006] The purpose of this utility model is to provide a fire-fighting mechanism testing device for fire lanes, so as to solve the problems of limited functionality and inability to fix the position mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A fire escape route fire mechanism testing device includes a tubular body. A fixed base is installed at the lower end of the tubular body. The fixed base is cuboid, and a push block is installed through the fixed base. The push block is cylindrical, and a push plate is fixedly installed at the lower end of the push block, with the push plate located below the fixed base. A transmission roller is installed inside the tubular body, and the bottom of the transmission roller is rotatably connected to the upper surface of the fixed base. A support block is installed on the outer side of the top of the tubular body. A threaded rod is connected to the upper end of the transmission roller, and a threaded sleeve is threadedly connected to the upper side of the threaded rod. The testing device body is connected to the outer side of the upper end of the threaded sleeve.

[0009] Preferably, the fixing base is provided with two suction cups on both the left and right sides of the front, and the suction cups are attached to the vicinity of the facility to be tested. The fixing base is configured to fix the structure according to the test requirements.

[0010] By adopting the above technical solution, the suction cup on the front of the fixed base can stably attach the testing device to the wall or other locations near the facility to be tested, so that the device will not shake or shift during the test, ensuring the accuracy of the test data and improving the stability of the test.

[0011] Preferably, the fixed base has a vertically penetrating groove inside, and the push block passes through the groove to form an up-and-down sliding structure, and the push block is driven to move up and down by the push plate.

[0012] The above technical solution uses a sliding structure formed by the groove inside the fixed base and the push block, which, together with the push plate, allows the operator to easily control the movement of the push block by pushing the push plate. The operation is simple and provides a convenient power transmission method for driving the transmission roller to rotate.

[0013] Preferably, a top post is fixedly installed inside the left side of the push block, and the top post extends through the left side of the push block, with the right end of the top post located inside the edge of the transmission roller.

[0014] By adopting the above technical solution, the top column on the left side of the push block penetrates the push block and is connected to the inside of the edge of the transmission roller. This allows the push force to be accurately transmitted to the transmission roller when the push block moves, ensuring the accuracy of power transmission and guaranteeing that the transmission roller rotates as expected.

[0015] Preferably, the outer edge of the transmission roller is surrounded by grooves, and the top post is located inside the grooves. The up-and-down movement of the top post drives the transmission roller to form a rotating structure.

[0016] With the above technical solution, the grooves on the outer side of the transmission roller cooperate with the top column. When the top column moves up and down, the grooves can guide the movement of the top column, making the transmission roller rotate more stably, avoiding slippage or jamming, and ensuring the smoothness of the entire transmission process.

[0017] Preferably, a limiting sleeve is fixedly installed above the support block, and the limiting sleeve is annular. Limiting grooves are opened on the left and right sides inside the limiting sleeve. Sliding strips are provided on the left and right sides of the threaded sleeve, and the sliding strips are slidably connected inside the limiting grooves.

[0018] By adopting the above technical solution, the limiting sleeve above the support block and its internal limiting groove cooperate with the sliding strips on both sides of the threaded sleeve to restrict the movement trajectory of the threaded sleeve, so that it can only move up and down within the range specified by the limiting groove, preventing the threaded sleeve from deviating during movement, ensuring the vertical lifting of the test device body, and improving the accuracy of the test.

[0019] Preferably, the upper end of the threaded sleeve is threadedly connected to an installation block, and the installation block has a threaded groove inside. The outer side of the threaded sleeve is threadedly connected to the threaded groove, and the top of the installation block is fixedly installed with the test device body.

[0020] By adopting the above technical solution, the mounting block at the upper end of the threaded sleeve and its internal threaded groove are connected by threads, which facilitates the quick replacement of different types of test device bodies, meets diverse testing needs, and further enhances the multifunctionality of the test device.

[0021] Compared with the prior art, the beneficial effects of this utility model are: the fire escape route testing device for fire-fighting mechanisms,

[0032] 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.

[0033] Please see Figure 1-7 This utility model provides a technical solution:

[0034] A fire-fighting mechanism testing device for fire escape routes includes a tubular body 1, a fixed base 2 installed at the lower end of the tubular body 1, the fixed base 2 being a cuboid, and a push block 5 being cylindrical inside the fixed base 2, with a push plate 4 fixedly installed at the lower end of the push block 5, and the push plate 4 being located below the fixed base 2. A transmission roller 10 is installed inside the tubular body 1, and the bottom of the transmission roller 10 is rotatably connected to the upper surface of the fixed base 2. A support block 6 is installed on the outer side of the top of the tubular body 1. A threaded rod 12 is connected and installed at the upper end of the transmission roller 10, and a threaded sleeve 13 is threadedly connected above the threaded rod 12. The testing device body 16 is connected and installed on the outer side of the upper end of the threaded sleeve 13.

[0035] The fixed base 2 has two suction cups 3 on both the left and right sides of its front. The suction cups 3 are attached to the vicinity of the facility to be tested. The fixed base 2 is configured to fix the device according to the test requirements. The suction cups 3 on the front of the fixed base 2 can stably attach the test device to the wall or other locations near the facility to be tested, so that the device will not shake or move during the test, ensuring the accuracy of the test data and improving the stability of the test.

[0036] A vertical groove 8 is vertically oriented through the interior of the fixed base 2, and a push block 5 passes through the groove 8 to form a sliding structure. The push block 5 moves up and down via a push plate 4. A top post 9 is fixedly installed inside the left side of the push block 5, extending through the left side of the push block 5. The right end of the top post 9 is located inside the edge of the transmission roller 10. A groove 11 is formed around the outer edge of the transmission roller 10, and the top post 9 is located inside the groove 11. The up-and-down movement of the top post 9 drives the transmission roller 10 to rotate. The sliding structure formed by the groove 8 and the push block 5 inside the fixed base 2, in conjunction with the push plate 4, facilitates the operator's movement by pushing the push block 5. The push plate 4 controls the movement of the push block 5, which is simple to operate and provides a convenient power transmission method for driving the transmission roller 10 to rotate. The top column 9 on the left side of the push block 5 passes through the push block 5 and is connected to the inside edge of the transmission roller 10. When the push block 5 moves, it can accurately transmit the thrust to the transmission roller 10, ensuring the accuracy of power transmission and ensuring that the transmission roller 10 rotates as expected. The groove 11 on the outside of the transmission roller 10 cooperates with the top column 9. When the top column 9 moves up and down, the groove 11 can guide the movement of the top column 9, making the transmission roller 10 rotate more stably and avoiding slippage or jamming, thus ensuring the smoothness of the entire transmission process.

[0037] A limiting sleeve 7 is fixedly installed above the support block 6. The limiting sleeve 7 is annular, and limiting grooves 71 are formed on both the left and right sides inside the limiting sleeve 7. Sliding strips 131 are provided on both the left and right sides of the threaded sleeve 13, and the sliding strips 131 are slidably connected to the inside of the limiting grooves 71. The upper end of the threaded sleeve 13 is threadedly connected to the mounting block 14, and the mounting block 14 has a threaded groove 15 inside. The outer side of the threaded sleeve 13 is threadedly connected to the threaded groove 15, and the test device body 16 is fixedly installed on the top of the mounting block 14. The limiting sleeve 7 above the support block 6 and the limiting grooves inside it are fixedly connected to the supporting block 6. The groove 71, in conjunction with the slide bars 131 on both sides of the threaded sleeve 13, restricts the movement trajectory of the threaded sleeve 13, allowing it to move up and down only within the range specified by the limiting groove 71. This prevents the threaded sleeve 13 from shifting during movement, ensuring the vertical lifting and lowering of the test device body 16 and improving the accuracy of the test. The mounting block 14 at the upper end of the threaded sleeve 13 and its internal threaded groove 15 are connected by threads, facilitating quick and easy replacement of different types of test device bodies 16 to meet diverse testing needs and further enhance the multifunctionality of the test device.

[0038] Working principle:

[0039] In use, the suction cup 3 on the front of the fixed base 2 is adsorbed onto a suitable fixed position near the facility to be tested, thus stabilizing the device. During operation, the pusher 4 pushes the pusher block 5 to move up and down within the slide groove 8 of the fixed base 2. The top column 9 on the left side of the pusher block 5 moves accordingly. The top column 9 is located within the groove 11 outside the transmission roller 10. The up and down movement of the top column 9 drives the transmission roller 10 to rotate around its bottom on the upper surface of the fixed base 2. When the transmission roller 10 rotates, the threaded rod 12 connected to its upper end rotates synchronously. The threaded sleeve 13 threaded above the threaded rod 12 rotates due to the rotation of its left and right sides. The slide bar 131 slides within the limiting groove 71 of the limiting sleeve 7, so the threaded sleeve 13 can only move up and down along the threaded rod 12, thereby driving the test device body 16 mounted on the upper end of the threaded sleeve 13 to move up and down, adjusting the height of the test device body 16 to adapt to different height testing requirements; when it is necessary to replace the test device body 16, the mounting block 14 is rotated. Since the threaded groove 15 inside the mounting block 14 is threadedly connected to the outer side of the threaded sleeve 13, the mounting block 14 can be unscrewed from the threaded sleeve 13, thus facilitating the replacement of different types of test device bodies 16 to complete different types of testing work.
