Description

Technical Field

[0001] This utility model relates to the field of roof ventilator technology, and in particular to an easy-to-disassemble roof ventilator. Background Technology

[0002] Roof ventilators, also known as roof natural ventilators or roof surface natural ventilators, are mainly based on the aerodynamic wind carrier shape theory that "when wind acts on an object, the windward side is pressure, and the leeward side and the side facing the wind are suction." Roof ventilators are divided into strip roof ventilators and spherical roof ventilators. Among them, strip roof ventilators are further divided into streamlined roof ventilators and thin roof ventilators. Most existing roof ventilators achieve ventilation through natural wind or through mechanical drive, without combining the two. Simply relying on natural wind to achieve ventilation makes it impossible to control the ventilation effect, while relying solely on mechanical drive to achieve ventilation results in energy waste.

[0003] A search revealed Chinese patent application number 202121664558.1, which discloses a roof ventilator that is easy to assemble and disassemble. This patent uses a solar lithium battery module to power a motor, which drives a guide vane to rotate via a shaft to achieve active ventilation. It combines natural ventilation and active ventilation, ensuring ventilation effect while saving energy. Although the above patent can prevent energy waste, it is troublesome to assemble and disassemble. Because multiple parts need to be fixed separately during installation, the workload of disassembly and assembly is large. In addition, the current roof ventilator does not have a deceleration effect in windy weather. In windy weather, the wind cap is heavy and the centrifugal force is strong, and the bearing bears a large load, which is prone to accelerated wear and shortens the service life. Therefore, it is necessary to design an easy-to-assemble and disassemble roof ventilator. Utility Model Content

[0004] The main objective of this invention is to provide an easy-to-disassemble roof ventilator, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A roof ventilator that is easy to assemble and disassemble includes a base cylinder and a ventilator. The base cylinder and the ventilator are movably connected. A support plate is fixedly connected to the lower surface of the base cylinder. Four columns are rotatably connected to one side of the upper surface of the support plate. A retaining plate is fixedly connected to the outer surface of each column near its bottom end. A threaded groove is formed on the outer surface of each column. A pressure cylinder is slidably connected to the outer surface of the base cylinder. The pressure cylinder is threadedly connected to the columns through the threaded groove. A bolt is provided on one side of the upper surface of the pressure cylinder. One end of the bolt penetrates the upper surface of the pressure cylinder and extends to the lower surface of the pressure cylinder. A threaded opening is formed on the lower surface of the base cylinder, and the threaded opening is threadedly connected to the bolt.

[0007] To ensure a good sealing effect, this utility model of an easily detachable roof ventilator uses two bolts, and the lower surface and inner wall of the pressure cylinder are both fixedly connected with rubber layers.

[0008] To provide support, as an easily detachable roof ventilator according to this utility model, a bracket is fixedly connected to the inner wall of the bottom cylinder near the top, and a top rod is fixedly connected to the upper surface of the bracket.

[0009] In order to achieve a rotating effect, as an easily detachable roof ventilator of this utility model, the outer surface of the top rod is rotatably connected to a fixing frame, and a disc is fixedly connected to the top of the fixing frame.

[0010] In order to enable rotation, as an easily detachable roof ventilator of this utility model, the disc is fixedly connected to the ventilator cylinder, and the disc is rotatably connected to the top rod.

[0011] In order to generate resistance, as an easily detachable roof ventilator of this utility model, a horizontal plate is fixedly connected to the top of the top rod, and resistance rings are fixedly connected to both ends of the horizontal plate.

[0012] To achieve a spring-like rebound, as an easily detachable roof ventilator according to this utility model, a base is fixedly connected to the upper surface of the disc, a sliding rod is fixedly connected to the inner side wall of the base, a spring is sleeved on the outer surface of the sliding rod, and a contact block is slidably connected to the outer surface of the sliding rod, with the contact block slidably connected to the base.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In this utility model, through the setting of the column, the clamping plate, the threaded groove and the pressure cylinder, during use, the bottom cylinder of the ventilator is first inserted into the roof mounting hole. Through the sliding effect between the pressure cylinder and the bottom cylinder, the pressure cylinder can be pressed to move downward. Utilizing the threaded connection between the pressure cylinder and the column, when the pressure cylinder moves downward, the threaded groove is subjected to force, which causes the column to rotate, thereby driving the clamping plate to rotate and unfold outward. When the pressure cylinder continues to move to the bottom, the adjacent clamping plates are close to a vertical state. The clamping plates and the pressure cylinder quickly lock the roof in place. The bolts are tightened into the threaded opening to fix it. When the wind blows the ventilator cap, airflow is generated for ventilation. When it needs to be removed, simply loosen the bolts, move the pressure cylinder upward to increase the distance between it and the bottom cylinder, and all four sets of clamping plates can be stored at the same time and then pulled out directly. It has the function of convenient assembly and disassembly.

[0015] 2. In this utility model, by setting up a resistance ring, a sliding rod, a spring, and a contact block, during use, after the ventilator is fixed, the natural wind blows the ventilator cylinder to rotate. At this time, the disc follows the rotation of the ventilator cylinder. When encountering severe weather with strong winds, the disc rotates at high speed, causing the contact block to generate centrifugal force. Through the sliding effect between the contact block and the sliding rod, it can slide outward within the base. At this time, the spring is deformed by the compression of the contact block. When the contact block contacts the resistance ring, the friction between the resistance ring and the contact block causes the disc to produce a deceleration effect. This prevents the ventilator cylinder from rotating too fast when the wind is strong, reduces the load and wear on the bearing, and greatly increases its service life. After the wind decreases, the spring pushes the contact block to rebound, moving away from the resistance ring, and it can rotate normally. Attached Figure Description

[0022] 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 protection scope of the present utility model.

[0023] Example

[0024] like Figure 1-5As shown, an easy-to-disassemble roof ventilator includes a base cylinder 1 and a ventilator 2. The base cylinder 1 and the ventilator 2 are movably connected. A support plate 3 is fixedly connected to the lower surface of the base cylinder 1. A column 4 is rotatably connected to one side of the upper surface of the support plate 3. There are four columns 4. A clamping plate 5 is fixedly connected to the side of the outer surface of the column 4 near the bottom. A threaded groove 6 is opened on the outer surface of the column 4. A pressure cylinder 7 is slidably connected to the outer surface of the base cylinder 1.

[0025] In this embodiment, the pressure cylinder 7 is threadedly connected to the column 4 through the threaded groove 6. A bolt 8 is provided on one side of the upper surface of the pressure cylinder 7. One end of the bolt 8 passes through the upper surface of the pressure cylinder 7 and extends to the lower surface of the pressure cylinder 7. A threaded port 9 is provided on the lower surface of the bottom cylinder 1, and the threaded port 9 is threadedly connected to the bolt 8.

[0026] In practical use, first insert the bottom cylinder 1 of the ventilator into the roof mounting hole. Through the sliding effect between the pressure cylinder 7 and the bottom cylinder 1, the pressure cylinder 7 can be pressed to move downwards. Utilizing the threaded connection between the pressure cylinder 7 and the column 4, the downward displacement of the pressure cylinder 7 causes the threaded groove 6 to be subjected to force, which in turn causes the column 4 to rotate, thereby driving the clamping plate 5 to rotate and unfold outwards. The pitch value of the threaded groove 6 can be set as needed. When the pressure cylinder 7 continues to move to the bottom, the adjacent clamping plates 5 are close to a vertical state. The clamping plates 5 and the pressure cylinder 7 quickly lock the top and bottom of the roof together. Tighten the bolt 8 into the threaded opening 9 to fix it. When the wind blows the ventilator cap 2, it generates airflow for ventilation. When it needs to be removed, simply loosen the bolt 8, move the pressure cylinder 7 upwards to increase the distance between it and the support plate 3, and all four sets of clamping plates 5 can be stored at the same time and then pulled out directly. It has the function of easy disassembly and assembly.

[0027] In this embodiment, there are two bolts 8, and rubber layers 10 are fixedly connected to the lower surface and inner wall of the pressure cylinder 7.

[0028] In practical use, the rubber layer 10 on the inner wall of the pressure cylinder 7 ensures a sealing effect when the pressure cylinder 7 and the bottom cylinder 1 slide against each other. The rubber layer 10 at the bottom ensures good sealing performance after the pressure cylinder 7 is fixed in contact with the roof, preventing rain leakage.

[0029] In this embodiment, a bracket 11 is fixedly connected to the inner wall of the bottom cylinder 1 near the top, and a top rod 12 is fixedly connected to the upper surface of the bracket 11.

[0030] In practical use, the bracket 11 facilitates the fixing of the top rod 12, providing a supporting effect. The top rod 12 facilitates the fixing of the disc 14 and the fixing frame 13.

[0031] In this embodiment, a fixing frame 13 is rotatably connected to the outer surface of the top rod 12, and a disc 14 is fixedly connected to the top of the fixing frame 13.

[0032] In practical use, the rotation effect of the fixed frame 13 and the top rod 12 enables the wind hood 2 to drive the disc 14 to rotate when it is subjected to wind force.

[0033] In this embodiment, the disc 14 is fixedly connected to the hood cylinder 2, and the disc 14 is rotatably connected to the top rod 12.

[0034] In practical use, the rotation effect of the disc 14 and the top rod 12 is used to make the windproof cap 2 rotate when it is blown by the wind.

[0035] In this embodiment, a horizontal plate 15 is fixedly connected to the top end of the top rod 12, and resistance rings 16 are fixedly connected to both ends of the horizontal plate 15.

[0036] In practical use, friction and resistance are generated when the resistance ring 16 contacts the contact block 20, which facilitates deceleration when the wind force is strong.

[0037] In this embodiment, a base 17 is fixedly connected to the upper surface of the disc 14, a slide rod 18 is fixedly connected to the inner side wall of the base 17, a spring 19 is sleeved on the outer surface of the slide rod 18, and a contact block 20 is slidably connected to the outer surface of the slide rod 18. The contact block 20 is slidably connected to the base 17.

[0038] In practical use, the friction between the resistance ring 16 and the contact block 20 causes the disc 14 to decelerate, thereby preventing the wind cap 2 from rotating too fast when the wind force is strong, and reducing the load and wear of the bearing.

[0039] Working principle: During use, the bottom cylinder 1 of the ventilator is first inserted into the roof mounting hole. Through the sliding effect between the pressure cylinder 7 and the bottom cylinder 1, the pressure cylinder 7 can be moved downwards. Utilizing the threaded connection between the pressure cylinder 7 and the column 4, the downward movement of the pressure cylinder 7 causes the threaded groove 6 to be subjected to force, which in turn causes the column 4 to rotate, thereby driving the clamping plate 5 to rotate and unfold outwards. When the pressure cylinder 7 continues to move to the bottom, the adjacent clamping plates 5 are nearly vertical, and the clamping plates 5 and the pressure cylinder 7 quickly and tightly fasten the roof from top to bottom. Tightening the bolts 8 into the threaded openings 9 secures the ventilator. When the wind blows the ventilator cap 2, airflow is generated for ventilation. At this time, the disc 14 rotates along with the ventilator cap 2. In severe weather with strong winds, the ventilator cap 2 rotates rapidly, causing the disc 14 to rotate at high speed, which in turn causes the contact block 20 to generate... Centrifugal force, through the sliding effect of contact block 20 and slide rod 18, allows the ventilator to slide outward within base 17. At this time, spring 19 is deformed by the compression of contact block 20. When contact block 20 continues to move and contacts resistance ring 16, the friction between resistance ring 16 and contact block 20 causes disc 14 to decelerate. This prevents the ventilator 2 from rotating too fast when the wind is strong, reduces the load and wear on the bearing, and greatly increases its service life. After the wind decreases, spring 19 pushes contact block 20 back and moves away from resistance ring 16, allowing it to rotate normally. The two bases 17 ensure the gravity balance of the ventilator for easy rotation. When it needs to be removed, simply loosen bolt 8, move pressure cylinder 7 upward to increase the distance from support plate 3, and simultaneously store the four sets of clamping plates 5 for direct removal. This provides a convenient disassembly and assembly function.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
