Technical Field
[0001] This utility model relates to the field of industrial environmental air purification technology, and in particular to a movable universal cover. Background Technology
[0002] A fume hood is an air purification device used in industrial environments to effectively remove harmful gases, odors, and particulate matter from the air, ensuring the health and safety of workers. It is commonly used in chemical plants, laboratories, workshops, and other similar spaces to ensure air quality meets safety standards.
[0003] A search revealed Chinese patent number CN201920731628.7, which discloses a universal exhaust pipe fixing device. The device includes a fixed base, a universal exhaust pipe fixedly connected to one side of the fixed base, an arched gas collection hood installed at one end of the universal exhaust pipe, and an exhaust port connected to the fixed base. Limiting blocks are provided at the four corners of the fixed base, and the exhaust port connecting the universal exhaust pipe is located at the center of the fixed base. A tapered bolt for fixing is provided near the outer side of the exhaust port. The beneficial effects of this device are: depending on the different slots opened on the ceiling, the movable block is slidable through a first sliding groove, changing the position of the limiting block at one end of the movable block, allowing the fixed base to be fixed to the ceiling with different slots, completing the initial fixing of the device; depending on the size of each ceiling panel, the position of the tapered bolt is moved through the movable groove, allowing one end of the tapered bolt to penetrate the ceiling and be fixed, thus fixing the device to the ceiling with the tapered bolt.
[0004] However, the above technical solutions have the following problems: when the universal hood is installed on top, it is generally fixed. This means that although the universal hood can suck in exhaust gas from different directions and angles, it can only be adjusted around a fixed point, thus limiting its applicability.

[0027] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.
[0028] like Figure 1-2 As shown, an embodiment of the present invention provides a movable universal cover, which includes: a translation component 1, an angle adjustment component 2, and a cover body 3. The translation component 1 has a translation end that can be translated along a first direction. One end of the angle adjustment component 2 is hinged to the translation end, and the other end is hinged to the cover body 3. One end of the angle adjustment component 2 can rotate relative to the other end and be stably maintained at any position of its stroke, so that the angle of the cover body 3 relative to the translation component 1 can be adjusted.
[0029] In this invention, the translation component 1 has a translation end that can be translated along a first direction. The angle adjustment component 2 is hinged to the translation end. The angle adjustment component 2 allows the cover 3 to adjust its angle relative to the translation component 1. In use, the angle adjustment component 2 and the cover 3 can be translated to an appropriate position first, and then the angle of the cover 3 relative to the translation component 1 can be adjusted to make the cover 3 completely fit the object being covered. In this application, the translation component 1 is provided, which allows the cover 3 to be translated, increasing its applicability and solving the problems in the prior art.
[0030] Specifically, the translation component 1 includes a sliding track 11 and a slider 12. The sliding track 11 is fixed to a reliable top surface, and the slider 12 is slidably connected to the sliding track 11. The slider 12 can move along the sliding track 11 and stably maintain any position within its sliding stroke. The angle adjustment component 2 is fixed to the slider 12. The slider 12 moves along the sliding track 11, thereby driving the angle adjustment component 2 and the cover 3 to adjust their positions.
[0031] Furthermore, in some feasible embodiments, the slider 12 includes a slider that is slidably connected to the sliding track 11. The slider is capable of moving along the sliding track 11 and being stably maintained at any position within its sliding stroke. The angle adjustment component 2 is fixed to the slider.
[0032] In this embodiment, the sliding body 12 includes a sliding ball 121, an elastic element 122, and a telescopic cylinder 123. A groove 111 matching the sliding ball 121 is formed on the sliding track 11. The sliding ball 121 is movably embedded in the groove 111. One end of the elastic element 122 is fixed to the inner wall of the groove 111, and the other end abuts against the sliding ball 121. The movable end of the telescopic cylinder 123 abuts against the side of the sliding ball 121 away from the elastic element 122. The angle adjustment component 2 is fixed to the sliding ball 121. In use, the movable end of the telescopic cylinder 123 extends and retracts, cooperating with the elastic element 122 to push the sliding ball 121 to move within the groove 111, thereby causing the angle adjustment component 2 and the cover 3 to move relative to the translation component 1.
[0033] Furthermore, the sliding body 12 also includes a first abutment piece 124 and a second abutment piece 125. One side of the first abutment piece 124 is fixed to the end of the elastic member 122, and the other side forms a first abutment surface that abuts against the sliding ball 121. One side of the second abutment piece 125 is fixed to the movable end of the telescopic cylinder 123, and the other side forms a second abutment surface that abuts against the sliding ball 121. The purpose of providing the first abutment piece 124 and the second abutment piece 125 is to stabilize the contact effect between the elastic member 122, the telescopic cylinder 123, and the sliding ball 121.
[0034] Furthermore, the elastic element 122 is a spring, one end of which is fixed to the inner wall of the groove 111, and the other end is fixed to the first abutment piece 124.
[0035] Furthermore, the translation component 1 includes at least one fixing component 13, which is fixed on the sliding track 11 and has two relatively displaceable inner support abutment surfaces. When the inner support abutment surfaces abut against the fixing surfaces, the sliding track 11 and the fixing surfaces are relatively fixed.
[0036] Furthermore, the fixing component 13 includes a first inner support 131, a second inner support 132, and a telescopic component 133. The telescopic component 133 is fixed on the sliding track 11 and has two relatively displaceable connecting ends. One end of the first inner support 131 and the second inner support 132 are respectively connected to both ends of the telescopic component 133, and the other ends of the first inner support 131 and the second inner support 132 form the inner support abutment surface. In use, the telescopic component 133 is adjusted to extend or retract at both ends, causing the first inner support 131 and the second inner support 132 to abut against the two fixed surfaces, thereby fixing the translation component 1.
[0037] In some feasible embodiments, the telescopic member 133 is a double-headed cylinder, and the two telescopic ends of the double-headed cylinder are respectively fixed to the first inner support member 131 and the second inner support member 132. The two telescopic ends of the double-headed cylinder extend and retract, driving the first inner support member 131 and the second inner support member 132 to move relative to each other.
[0038] In this embodiment, the telescopic member 133 includes a threaded seat 133a, a threaded rod 133b, a lifting block 133c, two hinge bars 133d, two sliding rods 133e, and a limiting block 133f. The threaded seat 133a and the limiting block 133f are fixed on the outer wall of the sliding track 11. The threaded seat 133a has a threaded hole, and the threaded rod 133b passes through the threaded hole. One end of the threaded rod 133b is fixed to the lifting block 133c. A plurality of hinge bars 133d are provided on both sides of the lifting block 133c. One end of the hinge bar 133d is hinged to one end of the lifting block 133c, and the other end is hinged to the sliding rod 133e. The other end of the sliding rod 133e is movably passed through the limiting block 133f and fixed to the first inner support member 131 or the second inner support member 132. In use, the threaded rod 133b is rotated to raise or lower the lifting block 133c relative to the threaded seat 133a, and then the sliding rod 133e is pushed or pulled by the hinge bar 133d. The sliding rod 133e drives the first inner support member 131 or the second inner support member 132 to move relative to or away from each other, so as to achieve the fixation of the inner support.
[0039] Furthermore, in some feasible embodiments, the angle adjustment component 2 includes a metal bellows, one end of which is connected to the cover 3, and the other end is connected to the sliding ball 121. The metal bellows is a thin-walled pipe with multiple annular corrugated structures, typically made of metal materials such as stainless steel or copper. Its unique design gives it good flexibility and pressure resistance, allowing it to be bent into various angles without compromising structural integrity and adapting to complex installation environments.
[0040] In this embodiment, the angle adjustment component 2 includes several connecting rods 21 and several locking hinges 22. The connecting rods 21 are connected end to end in sequence. The connecting rod 21 at the first end is hinged to the cover 3, and the connecting rod 21 at the last end is hinged to the translation component 1. The connecting rods 21 are hinged to each other through the locking hinges 22. In use, the connecting rods 21 rotate relative to each other to adjust the angle of the cover 3. The angle between the connecting rods 21 is locked by the locking hinges 22.
[0041] Specifically, the cover 3 is provided with an air extraction hole for extracting gas from the cover 3; when an external device is connected to the air extraction hole, it can extract gas from the cover 3.
