Technical Field
[0001] This utility model belongs to the technical field of machinery protection equipment, specifically relating to a small machinery protection shed. Background Technology
[0002] Small machinery plays a vital role in various construction scenarios, such as construction sites. Welding machines are among the most commonly used equipment in construction, indispensable in processes such as rebar welding and steel structure erection. When working, welding machines generate high temperatures, intense light, and sparks. These factors not only threaten the personal safety of operators but also easily damage the welding machines themselves. If welding machines are exposed to harsh construction environments for a long time, such as being exposed to rain or dust, their internal electronic components are prone to moisture and short circuits, leading to equipment failure, affecting construction progress, and even potentially causing safety accidents.
[0003] However, most current protective sheds are steel cage structures made of steel frames. Although they can protect small machinery from collisions, the steel cages are usually open on all sides, making it easy for dust from the construction site to enter the small machinery. At the same time, when used outdoors, rainwater can easily enter the small machinery, causing short circuits and damage to the electronic components inside, which brings a lot of inconvenience to use. Therefore, the applicant proposes a protective shed for small machinery to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide a protective shed for small machinery. When not in use, the protective curtain can be used to cover the steel cage frame, preventing dust from entering the steel cage frame and adhering to the small machinery. At the same time, when used outdoors, it can effectively block rainwater, preventing rainwater from entering the small machinery and causing short circuits and damage to electronic components, thus bringing more convenience to users.

[0030] Example 1:
[0031] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a small machinery protective shed includes:
[0032] The protective mechanism 2 and the locking mechanism 3 assembled at the bottom of the protective mechanism 2, and the dustproof mechanism 1 assembled around the protective mechanism 2;
[0033] The protective mechanism 2 includes a base 23, a steel cage frame 21 is fixedly installed on the top of the base 23, and a movable door 22 is hinged to one side of the base 23;
[0034] The locking mechanism 3 includes a movable frame 31 that is slidably mounted on the bottom of the base 23. A locking post 32 extending to the bottom of the movable door 22 is fixedly mounted on the top of the movable frame 31. A locking hole 26 corresponding to the locking post 32 is opened at the bottom of the movable door 22.
[0035] The dustproof mechanism 1 includes a protective top 11 fixedly installed on the top of the steel cage frame 21 and a movable frame 14 slidably installed around the perimeter of the steel cage frame 21. A protective curtain 13 is rolled up around the inner wall of the protective top 11, and the bottom of the protective curtain 13 is fixedly connected to the top of the movable frame 14.
[0036] As can be seen from the above, by pressing the movable frame 31 downwards by stepping on it during use, the locking pin 32 can be pulled out from the locking hole 26, making it easy to flip the movable door 22 downwards so that one end of the movable door 22 contacts the ground, making the movable door 22 tilted and forming a ramp. This allows small tools to be easily moved into the steel cage frame 21 along the tilted movable door 22, and also makes it easy to move small tools out of the steel cage frame 21, facilitating the installation and removal of small tools. By flipping the movable door 22 upwards and standing it upright, the movable frame 31 can be moved upwards to reset, allowing the locking pin 32 to be reinserted into the locking hole 26, making it easy to lock the movable door 22 and prevent it from flipping over. The steel cage frame 21 can also protect small tools and prevent collisions between them and external objects.
[0037] When stationary, by sliding the movable frame 14 downwards along the outer perimeter of the steel cage 21, the protective curtains 13 around the perimeter can be pulled downwards simultaneously, facilitating the covering of the steel cage 21. The protective curtains 13 are made of breathable and waterproof fabric, allowing the small machinery inside to ventilate and dissipate heat normally while providing dust and water protection. This prevents dust from entering the steel cage 21 and adhering to the small machinery. When used outdoors, they effectively block rainwater, preventing rainwater from entering the steel cage 21 and causing short circuits or damage to the electronic components inside the small machinery, thus providing greater convenience for users.
[0038] Depend on Figure 6 It can be seen that the inner wall of the protective top 11 is rotatably equipped with a rotating roller 12 for the protective curtain 13 to be rolled up, and the rotating rollers 12 are connected by a bevel gear set 16.
[0039] As can be seen from the above, the rotating roller 12 can facilitate the raising and lowering of the protective curtain 13, and the bevel gear set 16 can enable the rotating rollers 12 around the perimeter to rotate simultaneously and in the same direction, facilitating the simultaneous raising and lowering of the protective curtain 13.
[0040] For details, please refer to Figure 5 and Figure 6 As shown, a turntable 15 is fixedly installed at the front end of the rotating roller 12, and the turntable 15 extends to the front end of the protective top 11.
[0041] As can be seen from the above, by using the turntable 15, one of the rollers 12 can be easily driven to rotate, and with the bevel gear set 16, all four rollers 12 can be driven to rotate at the same time, making the operation convenient and quick.
[0042] For details, please refer to Figure 4As shown, the movable frame 31 and the base 23 are slidably installed together by a slider 35, and the front and rear ends of the base 23 are provided with sliding grooves 27 for the slider 35 to slide.
[0043] As can be seen from the above, by sliding the slider 35 along the slide groove 27, the movable frame 31 can move vertically up and down stably, avoiding the movable frame 31 from tilting.
[0044] Example 2:
[0045] refer to Figure 2 and Figure 4 As shown, a tension spring 34 is fixedly installed between the movable frame 31 and the base 23, and a caster wheel 24 is fixedly installed at the bottom of the base 23.
[0046] As can be seen from the above, the tension spring 34 can apply a pulling force to the movable frame 31. When the movable door 22 flips upward, the tension spring 34 can be used to drive the movable frame 31 to move upward to reset, so that the locking pin 32 can be inserted into the locking hole 26 to automatically lock the movable door 22. The movable wheel 24 can be used to easily move the device to a suitable position for use.
[0047] refer to Figure 4 As shown, a pedal 33 is fixedly installed on one side of the movable frame 31, and anti-slip textures are distributed on the top of the pedal 33.
[0048] As can be seen from the above, by stepping on the pedal 33, the movable frame 31 can be moved downwards, which facilitates the unlocking and unlocking of the movable door 22 and the downward flipping and opening of the movable door 22.
[0049] refer to Figure 5 As shown, a support bar 25 is fixedly installed on the inner wall of the steel cage frame 21, and the support bar 25 is in contact with the inner wall of the protective curtain 13.
[0050] As can be seen from the above, the support strip 25 can make contact and fit the edge of the protective curtain 13, which can easily form a sealing effect between the steel cage frame 21 and the edge of the protective curtain 13, avoiding the gap between the edge of the protective curtain 13 and the steel cage frame 21, making it difficult for dust and rainwater to enter the interior of the steel cage frame 21, thus improving the protective effect.
[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
