Description

Technical Field

[0001] The utility model relates to the technical field of hood bases, in particular to a novel hood base. Background Art

[0002] Many industrial plants, especially those made of colored steel plates, have poor heat dissipation conditions and are extremely hot and stuffy in the summer, resulting in low work efficiency and reduced product quality. The addition of unpowered roof fans can effectively improve indoor air quality, provide a comfortable working environment, and increase work efficiency. Due to the special nature of production, many industries cause air pollution in the factory, which not only leads to low environmental quality, but also harms the health of employees in the long run. The installation of hoods can improve indoor ventilation and effectively protect health. The hoods currently used are generally unpowered hoods. Since the hood base is not easy to be damaged, in order to reduce maintenance costs, when the hood equipment is damaged, only the hood part needs to be replaced and maintained. However, due to the different manufacturers of the hoods, it is difficult to find a hood that is fully compatible with the hood base for installation. Therefore, it is not suitable for quick installation, and the hood base that has been traditionally installed is inconvenient to disassemble and repair. Utility Model Content

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0018] Reference Figure 1-5 The hood base of the utility model is a novel hood base, comprising a base 1 and a hood unit, wherein the hood unit comprises a mounting frame 3, which is firmly mounted above the base 1 through the mounting frame 3, and a support frame 4 is rotatably arranged on the top of the mounting frame 3, and a hood body 5 is fixedly arranged on the support frame 4, and the mounting frame 3 is surrounded by a T-shaped slot 6 with an opening downward, and a T-shaped slider 7 is slidably connected in the T-shaped slot 6, and an elastic friction sheet 8 is fixedly arranged on the side wall of the T-shaped slider 7, which is moved by friction between the elastic friction sheet 8 and the wall of the T-shaped slot 6, so as to realize free adjustment of the position of the connecting column 9, and the elastic friction sheet 8 is frictionally abutted against the inner wall of the T-shaped slot 6, and a connecting column 9 is fixedly arranged at the bottom of the T-shaped slider 7, and a plug-in block 10 is fixedly arranged at the bottom of the connecting column 9, and a locking interface 11 is arranged in the plug-in block 10, and four groups of locking units arranged in a ring array for locking and connecting with the plug-in block 10 are arranged around the top of the base 1.

[0019] Advantageously or exemplarily, the top of the base 1 is further provided with an annular bearing portion 2 extending upward.

[0020] Beneficially or exemplarily, the locking unit includes a plug-in hole 12, an embedding guide groove 13 is provided on the side of the plug-in hole 12 away from the center of the base 1, a wedge lock slider 14 is slidably connected in the embedding guide groove 13, and a pressing spring 15 is pressed and connected on the side of the wedge lock slider 14 away from the plug-in hole 12. The wedge lock slider 14 is automatically reset and locked by the elastic force of the pressing spring 15 itself, and a pull rod 16 is slidably connected on the side of the embedding guide groove 13 away from the plug-in hole 12, one side of the pull rod 16 is fixedly connected to the wedge lock slider 14, and the other side of the pull rod 16 is fixedly provided with a handle 17.

[0021] Advantageously or exemplarily, the handle 17 is located on the outside of the base 1 .

[0022] Advantageously or exemplarily, an air flow opening is provided in the middle of the base 1 and passes through the base 1 from top to bottom.

[0023] Advantageously or exemplarily, the elastic friction plate 8 is made of a wear-resistant metal material, thereby increasing the service life.

[0024] When the utility model is installed and used: first, the mounting bracket 3 is moved to the position just above the base 1, and then the connecting column 9 is moved so that the plug-in block 10 at the bottom of the connecting column 9 is in a relative position with the plug-in hole 12, and then the mounting bracket 3 is moved downward so that the bottom of the mounting bracket 3 is placed on the top of the annular bearing portion 2, and the plug-in block 10 is inserted into the plug-in hole 12. Due to the downward squeezing of the plug-in block 10, the wedge lock slider 14 overcomes the top pressure of the top pressure spring 15 and slides away from the plug-in hole 12 until the lock interface 11 moves to the relative position of the wedge lock slider 14. At this time, due to the top pressure of the top pressure spring 15, the wedge lock slider 14 is inserted into the lock interface 11, thereby realizing the locking of the connecting column 9. Since the locking units on the front and rear sides limit the left and right movement of the mounting bracket 3, and the locking units on the left and right sides limit the front and rear movement of the mounting bracket 3, the stable installation of the mounting bracket 3 is realized, and the unlocking work of the connecting column 9 is realized by pulling the handle 17, and then the mounting bracket 3 can be lifted up to complete the disassembly.

[0025] It is clear to those skilled in the art that various modifications to the above embodiments can be made without departing from the overall spirit and concept of the present invention. All of them fall within the protection scope of the present invention. The protection scheme of the present invention shall be subject to the claims attached to the present invention.
