Description

Technical Field

[0001] The utility model relates to the technical field of greenhouses and breeding greenhouses, and in particular to a ventilation nozzle. Background Art

[0002] A greenhouse refers to a facility that is light-transmitting, heat-insulating (or heating) and is used to cultivate plants or raise livestock. In seasons that are not suitable for the survival of animals and plants, it can provide a suitable living environment for the living environment of animals and plants. Generally, there are many livestock or plants raised inside greenhouses or breeding greenhouses. If the air in the greenhouse is not circulated for a long time, it will have a certain impact on the growth of animals and plants living in the greenhouse. When ventilating the room, the traditional greenhouse needs to lift up the entire piece of greenhouse plastic, and then put it down when it is not ventilated, or only open the doors on the front and back ends of the greenhouse for ventilation. The ventilation effect is not good and the operation is inconvenient. Therefore, how to ventilate the greenhouse quickly and conveniently is an important issue that needs to be solved in the current development of greenhouses. Utility Model Content

[0003] The utility model aims to solve the shortcomings existing in the prior art and proposes a ventilation nozzle, including a ventilation pipe, wherein a No. 1 fixing plate is integrally formed at the end of the ventilation pipe, and a notch is arranged on the No. 1 fixing plate; a tightening thread is arranged on the bottom peripheral side of the ventilation pipe body close to the No. 1 fixing plate, and a sealing thread is arranged on the top peripheral side of the ventilation pipe body away from the No. 1 fixing plate.

[0004] Preferably, it also includes a fixed sleeve connected to the tight mouth thread, a second fixed plate with the same diameter as the first fixed plate is provided at the bottom of the fixed sleeve, and an internal thread matching the tight mouth thread is provided on the inner side of the bottom of the fixed sleeve.

[0005] Preferably, the inner diameter of the fixing sleeve is equal to the outer diameter of the ventilation pipe.

[0006] Preferably, it also includes an air duct plugging cover, wherein the air duct plugging cover is provided with an internal thread that cooperates with the sealing thread.

[0007] Preferably, the outer edge of the air duct plugging cover is also provided with an anti-slip convex strip for facilitating loosening of the air duct plugging cover.

[0008] Compared with the existing technology, the utility model has the following beneficial effects: the ventilating nozzle is easy to install, and can be obliquely inserted into the hole pre-opened in the greenhouse through the notch, and then the ventilation duct can be easily installed at the hole by rotating the ventilation duct;

[0009] By setting the fixed sleeve and cooperating with the tight-mouth thread, the fixed sleeve can be conveniently fixed on the ventilation pipe body. At the same time, the No. 1 fixing plate and the No. 2 fixing plate are closely attached to the inside and outside of the greenhouse side wall, further ensuring the stability of the ventilation pipe body after installation.

[0010] The air duct plugging cover is provided in conjunction with the sealing thread provided on the ventilation duct body, which facilitates the installation of the air duct plugging cover on the ventilation duct body and facilitates the operator to seal or open the air outlet according to actual conditions, thereby solving the problem of inconvenient indoor ventilation in traditional agricultural greenhouses and animal husbandry.

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] Referring to the schematic diagram, the present embodiment provides a ventilation nozzle, which includes a ventilation pipe 1, wherein a No. 1 fixing plate 2 is integrally formed at the end of the ventilation pipe 1, and a notch 3 is arranged on the No. 1 fixing plate 2; a tightening thread 4 is arranged on the bottom circumferential side of the ventilation pipe 1 body close to the No. 1 fixing plate 2, and a sealing thread 5 is arranged on the top circumferential side of the ventilation pipe 1 body away from the No. 1 fixing plate.

[0018] Furthermore, it also includes a fixed sleeve 6 connected to the tight mouth thread 4, a second fixed plate 7 with the same diameter as the first fixed plate 2 is arranged at the bottom of the fixed sleeve 6, and an internal thread matching the tight mouth thread 4 is arranged on the inner side of the bottom of the fixed sleeve 6.

[0019] Furthermore, the inner diameter of the fixing sleeve 6 is equal to the outer diameter of the ventilation pipe 1 .

[0020] Furthermore, it also includes an air duct plugging cover 8 , and the air duct plugging cover 8 is provided with an internal thread that cooperates with the blocking thread 5 .

[0021] Furthermore, the outer edge of the air duct plugging cover 8 is also provided with an anti-slip convex strip 9 for facilitating the loosening of the air duct plugging cover.

[0022] Working principle:

[0023] When in use, first open a hole on the plastic wall of the greenhouse that matches the outer diameter of the ventilation pipe, then take out the ventilation pipe and obliquely insert one side of the notch 3 on the No. 1 fixing plate 2 into the hole, then rotate the ventilation pipe, and the notch will bring the No. 1 fixing plate into the greenhouse while rotating; at this time, take out the fixing sleeve 6, and put the fixing sleeve 6 on the ventilation pipe, when it is at the bottom, rotate the fixing sleeve 6 so that the internal thread of the fixing sleeve 6 is screwed with the tight mouth thread, and fix the fixing sleeve 6;

[0024] When ventilation or exhaust is not required in the greenhouse (or breeding house), the air duct plugging cover 8 is screwed to the end of the ventilation duct. When ventilation or exhaust is needed again, the air duct plugging cover 8 is screwed down.

[0025] In the above embodiments and use process, the ventilating nozzle is easy to install, and is inserted obliquely into the hole pre-opened in the greenhouse through the provided notch, and then the ventilating pipe body can be easily installed at the hole by rotating the ventilating pipe;

[0026] By setting the fixed sleeve and cooperating with the tight-mouth thread, the fixed sleeve can be conveniently fixed on the ventilation pipe body. At the same time, the No. 1 fixing plate and the No. 2 fixing plate are closely attached to the inside and outside of the greenhouse side wall, further ensuring the stability of the ventilation pipe body after installation.

[0027] The air duct plugging cover is provided in conjunction with the sealing thread provided on the ventilation duct body, which facilitates the installation of the air duct plugging cover on the ventilation duct body and facilitates the operator to seal or open the air outlet according to actual conditions, thereby solving the problem of inconvenient indoor ventilation in traditional agricultural greenhouses and animal husbandry.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
