TECHNICAL FIELD
[0001] The utility model relates to an access door structure, in particular to a waterproof access door structure. BACKGROUND
[0002] The top access door of the existing high-temperature dust collector is only designed with a locking structure, and the access door without a wind hook is easy to be blown open or moved by the wind in strong wind weather, resulting in instability of the door. Frequent wind movement can cause damage to the structure of the door, shortening the service life of the access door. When using this access door, water can easily penetrate in rainy days due to the absence of a rain blocking strip, causing the internal equipment and lines to be damp, which may cause short circuits or other faults. The access door lacking a rain blocking strip cannot effectively block dust and impurities from entering the interior, increasing the difficulty of internal cleaning. The access door without a rain blocking strip is easy to cause heat loss in winter and hot air to enter in summer, affecting the normal operation of the internal equipment. The access door without a rain blocking strip is easy to produce a large noise and vibration when opening and closing, affecting the use comfort.
[0003] In summary, the conventional access door without a wind hook and a rain blocking strip not only has poor performance in adverse weather conditions, but also may increase maintenance costs and safety hazards. Therefore, it is necessary to improve the wind hook and the rain blocking strip. The existing wind hook structure is fixed, and the design is not flexible enough to meet the needs of different access door opening degrees.
[0004] Therefore, the utility model designs a waterproof access door structure with adjusting function. UTILITY MODEL CONTENTS

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0029] Reference Figures 1-5 The specific embodiment adopts the following technical solution: a waterproof maintenance door structure, including a maintenance door panel 1, a door frame 2, a windproof hook 3 and a rainproof strip 4. The maintenance door panel 1 has windproof hooks 3 set at the four corners. One end of the windproof hook 3 is connected to the maintenance door panel 1, and the other end of the windproof hook 3 is set on the door frame 2. A rainproof strip 4 is provided at the contact point between the maintenance door panel 1 and the door frame 2. Both ends of the windproof hook 3 are made of φ12 round steel.
[0030] It is worth noting that the windproof hook 3 includes a first hook part 31, a second hook part 32, and a telescopic structure 33. The outer ends of the first hook part 31 and the second hook part 32 are fixed to the inspection door and the door frame, respectively. The inner ends of the first hook part 31 and the second hook part 32 are connected to the two ends of the telescopic structure 33.
[0031] It is worth noting that the telescopic structure 33 includes a main rod a, a support rod b, an anti-detachment plate c, a rotary locking positioning device d, and a support rod telescopic guide seat e. The two ends of the main rod a are inserted with the support rod b. The outer ends of the support rod b are fixed to the first hook 31 and the second hook 32, respectively. The anti-detachment plate c is provided on the inner side of the support rod b. The two ends of the main rod a are also provided with support rod telescopic guide seats e. The middle of the support rod telescopic guide seat e is provided with a guide hole through which the support rod b passes. The side wall of the support rod telescopic guide seat e is provided with a threaded hole. The threaded hole cooperates with the rotary locking positioning device d to lock and position the support rod.
[0032] It is worth noting that the main rod a is a hollow tube.
[0033] It is worth noting that the diameter of the guide hole is smaller than the diameter of the anti-off plate.
[0034] It is worth noting that the telescopic structure 33 can also be provided with elastic sleeves at both ends to increase the stability of the telescopic support rod.
[0035] In addition, the rain strip 4 is designed in a concave arc shape and is inclined to facilitate the flow of rainwater to a lower position.
[0036] The design of the windproof hook in the embodiment makes the access door stable even in strong wind conditions and prevents it from being blown open. The design of the rain strip effectively prevents rainwater from seeping into the gap between the access door and the door frame, protecting the internal equipment. The telescopic structure of the windproof hook can adjust the length according to the needs, adapt to access doors and door frames of different sizes, and also ensure that the access door is at different opening degrees. The design of the guide hole and the anti-off plate ensures the stability of the support rod during telescoping and prevents it from coming out. The rotary locking positioning device makes the adjustment and maintenance of the windproof hook more convenient. The concave arc design of the rain strip not only has strong functionality but also improves the overall aesthetic appearance.
[0037] The access door of the embodiment increases the windproof hook and rain strip, which not only improves its performance and safety in adverse weather conditions, but also prolongs its service life and reduces maintenance costs.
[0038] The basic principles and main features of the utility model and the advantages of the utility model are shown and described above. It should be understood by those skilled in the art that the utility model is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the utility model.
