Description

Technical Field

[0001] This utility model relates to the field of fan louver technology, specifically to a louver slow-closing structure and a louver. Background Technology

[0002] Fans are widely used in the livestock industry, primarily for ventilation and cooling in livestock sheds, and are one of the key pieces of equipment. Louvers, as an important component of the fan, serve to isolate the air from the outside and provide a seal. A small number of fan louvers use non-metallic materials such as PVC, but these materials have problems such as large gaps, light and air leakage, and poor strength and durability, so their application is limited. Most fan louvers use metal louvers because they are sturdy and durable.

[0003] However, in actual use, louvers mainly close using either spring force or gravity. When the fan stops exhausting air, the combined forces of the negative pressure inside the shed and the outside air cause the louvers to close violently, resulting in a loud clattering sound from the louvers colliding with each other. This can frighten the chickens and reduce egg production. Although electrically operated louvers can avoid this problem, their high cost, complex structure, and poor reliability have prevented their widespread adoption.

[0004] Some solutions attempt to reduce impact noise by attaching adhesive strips to the bottom of the metal blades, but these are prone to falling off during high-pressure water cleaning, and attaching strips to each blade is difficult to implement.

[0005] Current technology lacks an effective slow-closing and silent structure for louvers to ensure that the louvers descend slowly during closing, thereby effectively avoiding excessive impact noise between the louvers.

[0006] Therefore, existing technologies need further development. Utility Model Content

[0007] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a louver slow-closing structure and a louver to solve the technical problem of loud noise from the louvers colliding with each other when the louvers are closed in the related technology.

[0008] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: A louver slow-closing structure is provided, which is used to achieve slow closure of the louver blades. The louver slow-closing structure includes: a buffer frame, which is rotatably mounted on a mounting plate; a buffer part, which is located at one end of the buffer frame away from the louver's connecting rod, the shape of which is adapted to the shape of the end of the connecting rod, and the buffer part and the end of the connecting rod can be abutted against each other; a first damping part, which is located at one end of the buffer frame away from the buffer part, and a second damping part is mounted on the mounting plate corresponding to the first damping part, the first damping part and the second damping part cooperating to form a damping structure that hinders the rotation of the buffer frame.

[0009] Furthermore, the buffer frame includes a fixed seat, which is located at the end of the buffer frame away from the buffer part. The extending direction of the fixed seat is parallel to that of the mounting plate, and a first damping part is fixedly installed on the fixed seat.

[0010] Furthermore, the first damping part includes a magnetic element; and / or, the second damping part includes a magnetic element.

[0011] Furthermore, the buffer frame includes a first connecting part and a second connecting part that are connected to each other. The first connecting part has a buffer part on the side near the linkage rod, and the second connecting part has a fixing seat on the end away from the first connecting part.

[0012] Furthermore, the first connecting part is an arc-shaped structure; and / or, the second connecting part is an arc-shaped structure.

[0013] Furthermore, the buffer section has an arc-shaped structure.

[0014] Furthermore, the buffer frame includes a support frame disposed between the first connecting portion and the second connecting portion, the extension direction of the support frame being perpendicular to the mounting plate, and one end of the support frame near the mounting plate being hinged to the mounting plate.

[0015] Furthermore, the louver slow-closing structure includes a connecting seat, which is fixedly mounted on the mounting plate. The connecting seat has two opposing hinges on the side near the buffer frame, with the extension direction of the hinges perpendicular to the mounting plate. The support frame is hinged between the two hinges by the same pin.

[0016] A type of louver, comprising the aforementioned louver slow-closing structure.

[0017] Beneficial effects:

[0018] 1. In this embodiment, the slow-closing structure of the venetian blinds allows the connecting rod to decelerate instantly as it moves towards the buffer frame during closing. This deceleration, due to the damping mechanism, prevents sudden hard collisions and mechanical impacts, reducing the impact force and noise generated during closing. Compared to traditional spring-force closing or gravity-based natural closure methods, this slow-closing structure reduces direct mechanical impact through mechanical design, solving the technical problem of significant noise from the venetian blinds colliding during closing.

[0019] 2. Understandably, by setting the first damping part and the second damping part to work together, the damping structure provides additional resistance. The damping can prevent the buffer frame from rotating relative to the mounting plate, so that the buffer frame can decelerate slowly during the closing process. Attached Figure Description

[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0028] According to an embodiment of this utility model, a louver soft-closing structure is provided. Please refer to [link / reference]. Figures 1 to 5 The louver slow-closing structure is used to achieve the slow closing of the louver blades. The louver slow-closing structure includes: a buffer frame 1, which is rotatably mounted on a mounting plate 2; a buffer part 3, which is located at the end of the buffer frame 1 away from the louver's connecting rod 10, and the shape of the buffer part 3 is adapted to the shape of the end of the connecting rod 10, and the buffer part 3 and the end of the connecting rod 10 can be abutted against the ground; and a first damping part 4, which is located at the end of the buffer frame 1 away from the buffer part 3, and a second damping part is mounted on the mounting plate 2 corresponding to the first damping part 4. The first damping part 4 and the second damping part cooperate with each other to form a damping structure that hinders the rotation of the buffer frame 1.

[0029] It should be noted that the mounting plate 2 can be located on the side plate of the louver body, or integrated with the side plate, so that the buffer frame 1 can be set correspondingly to the end of the linkage rod 10. The mounting plate 2 can also be set outside the louver body, which can also achieve buffering of the linkage rod.

[0030] Understandably, by setting the first damping part 4 and the second damping part to work together, the damping structure provides additional resistance, enabling the buffer frame 1 to decelerate slowly during the closing process.

[0031] When the blinds close, as the linkage 10 moves towards the buffer frame 1, its end contacts the buffer part 3. Due to the damping mechanism, the linkage 10 can decelerate instantly, providing a buffering effect and avoiding sudden hard collisions and mechanical impacts, thus reducing the impact force and noise generated at the moment of closing. Compared to traditional spring-force closing or gravity-based natural closure methods, this slow-closing structure reduces direct mechanical impact through mechanical design, solving the technical problem of excessive noise from the louvers colliding with each other when the blinds close in related technologies.

[0032] In the louver soft-closing structure of this embodiment, see... Figure 2 The buffer frame 1 includes a fixed base 5, which is located at the end of the buffer frame 1 away from the buffer part 3. The extending direction of the fixed base 5 is parallel to that of the mounting plate 2. A first damping part 4 is fixedly mounted on the fixed base 5. By setting the fixed base 5, the first damping part 4 is installed, so that the first damping part 4 and the second damping part cooperate with each other.

[0033] In the louver soft-closing structure of this embodiment, see... Figure 2 The first damping part 4 includes a magnetic element; and / or, the second damping part includes a magnetic element. In this way, magnetic attraction is generated between the first damping part 4 and the second damping part by the magnetic element, so as to increase the damping when the buffer frame 1 rotates. The damping can hinder the rotation of the buffer frame 1 relative to the mounting plate 2, thereby slowing down the movement speed of the linkage 10.

[0034] Preferably, the first damping part 4 is a magnet, and the mounting plate 2 is made of iron. Therefore, the second damping part does not need to be installed with a magnet to form a damping mechanism. The first damping part 4 magnetically attracts the second damping part on the mounting plate 2 to achieve the function of deceleration.

[0035] Specifically, at the moment of impact, the impact force generated by the linkage 10 striking the buffer part 3 is greater than the attraction force generated by the magnetic component. This allows the first damping part 4 to separate from the second damping part, causing the buffer frame 1 to rotate, while simultaneously slowing down the linkage 10, thus achieving a buffering effect.

[0036] Understandably, when the blinds are opened, the linkage 10 moves away from the slow-closing structure, and the magnetic component of the first damping part 4 is attracted back to the mounting plate under the action of gravity; this process is repeated to achieve a mechanical buffering effect.

[0037] Preferably, when the first damping part 4 is a magnetic component, the louver slow-descent structure is installed at the top of the linkage 10.

[0038] In some embodiments, the first damping part 4 is a magnet, and the second damping part is also a magnet.

[0039] In some embodiments, the magnet may be installed at the second damping part, and the first damping part 4 may be made of iron.

[0040] In some embodiments, an elastic structure can be used as a damping mechanism, for example, a tension spring can be used to connect the first damping part 4 and the second damping part respectively.

[0041] In some embodiments, the first damping part 4 and the second damping part may be respectively made of friction plates to increase the frictional damping between them, so as to prevent the buffer frame 1 from rotating.

[0042] In the louver soft-closing structure of this embodiment, see... Figure 5 The buffer frame 1 includes a first connecting part 11 and a second connecting part 12 that are connected to each other. A buffer part 3 is provided on the side of the first connecting part 11 near the connecting rod 10, and a fixing seat 5 is provided on the end of the second connecting part 12 away from the first connecting part 11. In this way, when the connecting rod 10 hits the buffer part 3, the fixing seat 5 will move away from the mounting plate 2.

[0043] In the louver soft-closing structure of this embodiment, see... Figure 5 The first connecting part 11 has an arc-shaped structure; and / or the second connecting part 12 has an arc-shaped structure.

[0044] In some embodiments, both the first connecting part 11 and the second connecting part 12 adopt an arc-shaped structure. The arc-shaped structure can better disperse the force, which helps to alleviate the instantaneous impact force caused by wind pressure or other external factors. It can increase the structural strength of the buffer frame 1, make the slow-descent structure adaptable to different installation environments, and improve aesthetics and compactness.

[0045] In the louver soft-closing structure of this embodiment, see... Figure 5 The buffer part 3 has an arc-shaped structure. Specifically, the buffer part 3 adopts an arc-shaped surface, which increases the contact area between the connecting rod 10 and the buffer part 3, can better disperse the force, can increase the structural strength of the buffer part 3, and can make the connecting rod 10 move smoothly relative to the buffer part 3, making the louver closing process more stable and smooth, and further reducing the noise level.

[0046] In the louver soft-closing structure of this embodiment, see... Figure 5 The buffer frame 1 includes a support frame 13, which is disposed between the first connecting part 11 and the second connecting part 12. The extending direction of the support frame 13 is perpendicular to the mounting plate 2, and one end of the support frame 13 near the mounting plate 2 is hinged to the mounting plate 2. In this way, the buffer frame 1 can rotate about the hinge point between the support frame 13 and the mounting plate 2.

[0047] In the louver soft-closing structure of this embodiment, see... Figure 5 The louver slow-closing structure includes a connecting seat 6, which is fixedly mounted on the mounting plate 2. Two opposing hinge parts are provided on the side of the connecting seat 6 near the buffer frame 1, with the extension direction of the hinge parts perpendicular to the mounting plate 2. The support frame 13 is hinged between the two hinge parts via the same pin. In this way, the buffer frame 1 can rotate around the hinge parts, achieving rotatability of the buffer frame 1.

[0048] In some embodiments, the operation of the louver slow-closing structure is as follows: when the louvers are closed, the linkage rod 10 moves toward the direction close to the louver slow-closing structure. When the end of the linkage rod 10 contacts the buffer part 3, it decelerates instantly, thus providing a buffering effect. The magnetic component of the first damping part 4 leaves the mounting plate 2 and rotates with the buffer frame 1. When the louvers are opened, the linkage rod 10 moves away from the louver slow-closing structure. The magnetic component of the first damping part 4 is attracted back to the mounting plate 2 under the action of gravity.

[0049] In the venetian blinds of this embodiment, see Figure 1 The venetian blinds include the aforementioned venetian blind slow-closing structure.

[0050] The slow-closing structure of the louvers in this embodiment is applied to the fan louvers in poultry houses. The slow-closing structure can greatly reduce the impact force between the louvers. When closing, the impact force between the louvers is reduced to achieve a silent effect, avoiding excessive closing noise that may affect the egg production rate of poultry. It also reduces the impact between the louvers, preventing the zinc layer on the louver surface from peeling off and corroding due to violent impact. The slow-closing structure also prevents the louvers from deforming due to impact. As the usage time increases, the sealing performance of the louvers deteriorates. The slow-closing structure can adjust the damping effect and can be widely used for different models of metal louvers.
