Technical Field

[0001] This utility model belongs to the field of fume hood manufacturing technology, and specifically relates to a fume hood. Background Technology

[0002] Fume hoods are ventilation devices widely used in laboratories, chemical plants, pharmaceutical plants, and other fields. They are mainly used to exhaust harmful gases, odors, moisture, as well as flammable, explosive, and corrosive substances generated during experiments or production processes, providing a safe working environment for operators.

[0003] The regulating door of the fume hood is embedded in the slide rails on both sides of the fume hood and moves up and down along the slide rails. When the regulating door gets stuck in the slide rails, the regulating door needs to be disassembled for repair, which makes the maintenance of the regulating door difficult. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a fume hood that can effectively reduce the difficulty of maintenance.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fume hood includes a cabinet body and an adjustable door, wherein the cabinet body is provided with a sliding groove;

[0007] The adjustable door includes a door frame and a door body. The door body is disposed in the door frame. The door frame is provided with a mounting groove. A protrusion is installed in the mounting groove. The protrusion has a mounting end and a sliding end. The mounting end is placed in the mounting groove, and the sliding end passes through the door frame and is slidably connected to the sliding groove.

[0008] Optionally, the door frame is provided with a through hole, a first threaded portion is provided in the through hole, and a second threaded portion is provided on the protrusion to cooperate with the first threaded portion.

[0009] Optionally, the second threaded portion extends to the mounting end, which is used to engage with a tightening nut.

[0010] Optionally, the groove is an arc-shaped structure, and the protrusion is a round-headed structure with a sliding end that mates with the groove.

[0011] Optionally, the protrusion is a round-headed lead screw.

[0012] Optionally, the groove is a rectangular groove, and the protrusion is a rectangular block that mates with the groove.

[0013] Optionally, there are at least two protrusions, which are arranged sequentially on the door frame along the vertical direction of the door frame;

[0014] At least one of the protrusions is disposed on the upper part of the door frame, and at least one of the protrusions is disposed on the lower part of the door frame.

[0015] Optionally, two limiting blocks are also provided in the slide, and are respectively located at the top and bottom of the cabinet.

[0016] Optionally, the groove is made of plastic, and the raised sliding end is also made of plastic.

[0017] Optionally, both the groove and the protrusion are coated with lubricating oil.

[0018] As can be seen from the above technical solutions, when the sliding door and the cabinet get stuck during the sliding process, the distance between the protruding sliding end and the slide groove can be adjusted in the installation groove to make it larger, which can solve the problem of jamming. Compared with the existing technology, it is not necessary to remove the entire sliding door from the cabinet for maintenance, thus greatly reducing the difficulty of maintenance.

[0027] In view of this, the purpose of this utility model is to provide a fume hood that can effectively reduce the difficulty of maintenance.

[0028] 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 scope of protection of the present utility model. Please refer to... Figures 1 to 4 .

[0029] The exhaust fan disclosed in this embodiment of the utility model includes a cabinet body 100 and an adjustable door 200, and a sliding groove 101 is provided on the cabinet body 100.

[0030] The adjustable door 200 includes a door frame and a door body. The door body is set in the door frame. The door frame is provided with an installation groove 201. A protrusion 202 is installed in the installation groove 201. The protrusion 202 has an installation end and a sliding end. The installation end is placed in the installation groove 201, and the sliding end passes through the door frame and is slidably connected to the sliding groove 101.

[0031] When the sliding door 200 gets stuck in the cabinet 100 during the sliding process, the distance between the sliding end of the protrusion 202 and the slide groove 101 can be adjusted in the mounting groove 201 to make it larger, which can solve the problem of sticking. Compared with the existing technology, it is not necessary to remove the entire sliding door 200 from the cabinet 100 for maintenance, thus greatly reducing the difficulty of maintenance.

[0032] To facilitate the adjustment of the distance between the protrusion 202 and the slide groove 101, the door frame disclosed in this embodiment of the utility model is provided with a through hole, a first threaded part is provided in the through hole, and a second threaded part 2021 that mates with the first threaded part is provided on the protrusion 202. The first threaded part and the second threaded part 2021 are connected to each other so that the protrusion 202 can be screwed in or out of the through hole.

[0033] It should be noted that the second threaded portion 2021 extends to the mounting end, which is used to connect with the tightening nut.

[0034] This utility model embodiment does not limit the specific structure of the sliding end of the groove 101 and the protrusion 202. The groove 101 can be an arc-shaped structure, a rectangular structure, or other structures. As long as the structure meets the usage requirements of this utility model, it is within the protection scope of this utility model.

[0035] When the slide groove 101 is an arc-shaped structure, the sliding end of the protrusion 202 is a round head structure that mates with the slide groove 101; when the slide groove 101 is a rectangular structure, the protrusion 202 is a rectangular block that mates with the slide groove 101. In fact, it is sufficient as long as the slide groove 101 and the protrusion 202 can mate effectively.

[0036] As a preferred embodiment, the slide groove 101 disclosed in this utility model example has an arc-shaped structure, and the sliding end of the protrusion 202 has a round head structure that cooperates with the slide groove 101.

[0037] As a specific embodiment, the protrusion 202 disclosed in this utility model embodiment is a round-headed screw rod, wherein one end of the round-headed screw rod passes through the door frame and is connected to the slide groove 101, and the other end of the round-headed screw rod is placed in the mounting groove 201 and is connected to the tightening nut.

[0038] The present invention does not limit the number of protrusions 202. One, two or more protrusions 202 can be provided. As long as the number meets the requirements of the present invention, it is within the protection scope of the present invention.

[0039] As one embodiment, the protrusions 202 disclosed in this utility model embodiment are at least two, and are arranged sequentially on the door frame along the vertical direction of the door frame.

[0040] In order to achieve uniform stress, at least one protrusion 202 disclosed in the present invention is provided on the upper part of the door frame and at least one protrusion 202 is provided on the lower part of the door frame.

[0041] To prevent the sliding door 200 from slipping out of the slide groove 101, the slide groove 101 disclosed in this embodiment of the utility model is also provided with two limiting blocks, which are respectively provided at the top and bottom of the cabinet 100.

[0042] The slide 101 is made of plastic, and the sliding end of the protrusion 202 is also made of plastic, which not only has low material cost but is also easy to obtain.

[0043] As a further embodiment, both the groove 101 and the protrusion 202 disclosed in this utility model embodiment are coated with lubricating oil to further improve the lubricity when the protrusion 202 slides with the groove 101.
