Technical Field

[0001] This utility model relates to the field of self-rescue device testing technology, specifically a protective device for a coal mine self-rescue device airtightness testing instrument. Background Technology

[0002] A coal mine self-rescue device is a safety protection device used underground in coal mines. It is primarily used in the event of accidents such as fires, gas explosions, coal dust explosions, and coal and gas outbursts. Workers wear it over their mouth and nose to prevent dangerous situations such as oxygen deficiency, suffocation, and poisoning caused by excessive concentrations of harmful gases. It is a crucial respiratory protection device for underground personnel, saving lives in critical moments. Therefore, we must attach great importance to the use, management, and maintenance of self-rescue devices to ensure they are always in good working order.

[0003] However, existing self-rescue device testing devices are usually carried in protective cases and need to be manually removed during use, which is complicated and troublesome. To address this problem, a protective device for a coal mine self-rescue device airtightness testing instrument is provided. Utility Model Content

[0004] The purpose of this utility model is to provide a protective device for a coal mine self-rescue device airtightness tester, so as to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: A protective device for a coal mine self-rescue device airtightness tester, including a protective box, a rotating column rotatably connected to the top of the protective box via a bearing, a protective cover fixedly sleeved on the outer wall of the rotating column, multiple guide rods provided in the inner cavity of the protective box, lifting plates slidably sleeved on the outer walls of the multiple guide rods, a frame provided at the front end of the lifting plate, a sliding assembly provided in the inner cavity of the frame, two clamping plates provided at the top of the sliding assembly, a coal mine self-rescue device tester fixed between the two clamping plates, a lifting assembly provided on one side of the outer wall of the protective box, the lifting assembly extending into the inner cavity of the protective box and fixedly connected to the lifting plate.

[0005] Preferably, the lifting assembly includes a gear, a slide rail, a moving rod, and a rack. The gear is fixedly sleeved on the outer wall of the rotating column. The slide rail is opened on one side of the outer wall of the protective box. The moving rod is slidably embedded in the inner cavity of the slide rail and fixedly connected to one side of the outer wall of the lifting plate. The rack is located at the other end of the moving rod.

[0006] Preferably, the rack meshes with a gear.

[0007] Preferably, the protective cover has a handle at its top and a latch on its surface.

[0008] Preferably, the sliding assembly includes a lead screw, a knob, sliders, and a limiting assembly. One end of the lead screw is rotatably connected to the left side of the inner cavity of the frame via a bearing, and the other end of the lead screw extends to the right end of the frame and is fixedly connected to the knob. The two sliders are respectively screwed to the left and right sides of the outer wall of the lead screw and are respectively fixedly connected to the two clamping plates. The limiting assembly is located at the front end of the lifting plate and is fixedly connected to the two sliders.

[0009] Preferably, the threads on the left and right sides of the outer wall of the lead screw are arranged opposite to each other.

[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: a protective device for a coal mine self-rescue device airtightness tester, comprising a protective box 1, a rotating column 2 rotatably connected to the top of the protective box 1 via a bearing, a protective cover 3 fixedly sleeved on the outer wall of the rotating column 2, multiple guide rods 7 arranged in the inner cavity of the protective box 1, a lifting plate 8 slidably sleeved on the outer wall of the multiple guide rods 7, a frame 11 arranged at the front end of the lifting plate 8, a sliding assembly arranged in the inner cavity of the frame 11, two clamping plates 15 arranged at the top of the sliding assembly, a coal mine self-rescue device tester fixed between the two clamping plates 15, and a lifting assembly arranged on one side of the outer wall of the protective box 1, the lifting assembly extending to the protective box 1. The inner cavity of the box 1 is fixedly connected to the lifting plate 8. When the protective cover 3 is opened, the rotating column 2 drives the gear 5 to rotate, which in turn causes the rack 10 to drive the lifting plate 8 to slide upward along the slide rail 6 and the guide rod 7 through the moving rod 9, extending it out of the inner cavity of the protective box 1. This allows the detector to be taken out directly, solving the problem that the existing self-rescue device detection device is usually placed in the protective box 1 for carrying, and needs to be manually taken out when in use, which is complicated and troublesome. Through the setting of the sliding component, the two clamping plates 15 can slide simultaneously towards the top center of the lifting plate 8 to clamp and fix the detector, which is convenient for disassembly and assembly of the detector. The operation is simple and convenient.

[0021] In this embodiment, the lifting assembly includes a gear 5, a slide rail 6, a moving rod 9, and a rack 10. The gear 5 is fixedly sleeved on the outer wall of the rotating column 2. The slide rail 6 is opened on one side of the outer wall of the protective box 1. The moving rod 9 is slidably embedded in the inner cavity of the slide rail 6 and fixedly connected to one side of the outer wall of the lifting plate 8. The rack 10 is located at the other end of the moving rod 9. When the protective cover 3 is opened, the rotating column 2 can drive the gear 5 to rotate, thereby causing the rack 10 to drive the lifting plate 8 to slide upward along the slide rail 6 and the guide rod 7 through the moving rod 9 and extend out of the inner cavity of the protective box 1. Thus, the detector can be directly taken out, which solves the problem that the existing self-rescue device detection device is usually placed in the protective box 1 for carrying, and needs to be manually taken out when in use, which is complicated and troublesome.

[0022] In this embodiment, the rack 10 meshes with the gear 5, which allows the rack 10 to slide up and down when the gear 5 rotates.

[0023] In this embodiment, a handle 4 is provided at the top of the protective cover 3, and a latch is provided on the protective cover 3.

[0024] In this embodiment, the sliding assembly includes a lead screw 13, a knob 12, sliders 14, and a limiting assembly. One end of the lead screw 13 is rotatably connected to the left side of the inner cavity of the frame 11 via a bearing, and the other end of the lead screw 13 extends to the right end of the frame 11 and is fixedly connected to the knob 12. Two sliders 14 are respectively screwed to the left and right sides of the outer wall of the lead screw 13 and are respectively fixedly connected to two clamping plates 15. The limiting assembly is located at the front end of the lifting plate 8 and is fixedly connected to the two sliders 14. Rotating the knob 12 causes the knob 12 to drive the lead screw 13 to rotate, thereby causing the opposing threads on the left and right sides of the outer wall of the lead screw 13 to generate opposing thread rotational forces. Under the limiting action of the limiting groove 16 and the limiting block 17, the two sliders 14 slide simultaneously toward the middle of the lead screw 13, and the two clamping plates 15 slide simultaneously toward the top center of the lifting plate 8 to clamp and fix the detector, which facilitates the disassembly and assembly of the detector. The operation is simple and convenient.

[0025] In this embodiment, the threads on the left and right sides of the outer wall of the lead screw 13 are arranged opposite to each other, so that when the lead screw 13 rotates, the left and right sides of its outer wall generate relative thread rotation force, so that the two sliders 14 slide relative to each other simultaneously under the combined action of the limiting groove 16 and the limiting block 17.

[0026] In this embodiment, the limiting component includes a limiting groove 16 and limiting blocks 17. The limiting groove 16 is opened at the front end of the lifting plate 8. Both limiting blocks 17 are slidably embedded in the inner cavity of the limiting groove 16 and are respectively fixedly connected to two sliders 14. Under the joint action of the limiting groove 16 and the limiting blocks 17, the sliders 14 are prevented from rotating with the lead screw 13 when the lead screw 13 rotates, which improves the stability of the sliding component during use. The inner cavity of the limiting groove 16 and the outer wall of the limiting block 17 are adapted to each other and are both in the shape of "T". This ensures that one end of the limiting block 17 is always embedded in the inner cavity of the limiting groove 16, which improves the stability of the limiting component during use.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
