Description

Technical Field

[0001] This invention belongs to the field of building kitchen and bathroom exhaust duct devices, and in particular relates to a clamping mechanism and valve body for an exhaust duct flow equalizer. Background Technology

[0002] When installing a flow equalizer on an exhaust duct, the dimensions of the exhaust duct and the flow equalizer often do not perfectly match. To facilitate installation, the exhaust duct is designed to be larger than the flow equalizer. To address this issue, a clamping mechanism needs to be designed to ensure the secure installation of different models of flow equalizers and exhaust ducts. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides a clamping mechanism and valve body for the exhaust duct flow equalizer that is adaptable to different sizes of flow equalizers and exhaust ducts, is easy to install, and has a stable structure after installation.

[0004] The technical solution adopted by this invention to solve its technical problem is: a clamping mechanism for an exhaust duct flow equalizer, comprising:

[0005] The clamping plate abuts against the flow equalizer;

[0006] The connecting rod is connected to the clamping plate and has a drive end;

[0007] The support section forms an inclined surface that can resist external carriers;

[0008] An external force is applied to the drive end to move the connecting rod. The inclined action surface moves against the external carrier, driving the clamping plate to move against the flow equalizer, thereby causing the flow equalizer to move up or down.

[0009] In order to facilitate installation, the size of the exhaust channel of the external carrier is designed to be larger than that of the flow equalizer. The flow equalizer is moved up or down by the clamping mechanism so that it is stably abutted against the external carrier. Even if the size of the exhaust channel does not match the flow equalizer, the flow equalizer can still be stably installed. It is suitable for different models of flow equalizers and different installation scenarios.

[0010] Furthermore, a blocking surface is formed at the end of the support portion. The blocking surface can prevent the support portion from slipping due to excessive movement against the external carrier, thus ensuring the stability of the overall mating structure.

[0011] Furthermore, the flow equalizer has an inclined surface, and at least a portion of the connecting rod is parallel to this inclined surface. The inclined surface at the bottom or top of the flow equalizer allows for upward or downward movement of the flow equalizer when the connecting rod pulls the clamping plate at an angle, making operation more convenient and ensuring a more secure clamping and mounting of the flow equalizer by the clamping mechanism and the external carrier.

[0012] Furthermore, the inclined surface slopes upwards and is located at the bottom of the flow equalizer. Positioning the inclined surface at the bottom of the flow equalizer guides gas flow and facilitates the tilting movement of the clamping mechanism to support the flow equalizer upwards.

[0013] Furthermore, the top of the flow equalizer is provided with positioning teeth for positioning and installation with an external carrier. The positioning teeth and clamping mechanism are respectively located on the upper and lower sides of the flow equalizer, resulting in a more reasonable structural design and facilitating engagement with the external carrier, ensuring the stable installation of the flow equalizer.

[0014] Furthermore, the inclined surface slopes downwards and is located at the top of the flow equalizer, forming a travel groove into which the clamping plate partially extends. The clamping mechanism has various structural forms to adapt to different installation scenarios.

[0015] Furthermore, the bottom of the flow equalizer is provided with positioning teeth that can be positioned and installed with an external carrier.

[0016] Furthermore, the bottom of the flow equalizer is horizontal.

[0017] Furthermore, the drive end extends through the flow equalizer. This extension of the drive end through the flow equalizer facilitates the movement of the clamping plate from the outside, making the installation operation more convenient.

[0018] Furthermore, a rotating component is threadedly connected to the drive end. Applying external force to rotate the rotating component drives the connecting rod to move relative to the flow equalizer. By converting the rotation of the rotating component into the movement of the connecting rod relative to the flow equalizer, the operation is simple and labor-saving.

[0019] Furthermore, the support portion is connected to the clamping plate. The support portion and the clamping plate are integrally connected, which facilitates processing. When the connecting rod moves, the upper and lower support portions and the clamping plate move relatively in unison, making the clamping of the flow equalizer more stable and avoiding uneven force distribution.

[0020] The present invention also discloses a valve body having an exhaust port, a valve plate unit, and a flow equalizer provided corresponding to the exhaust port, wherein the flow equalizer has the above-mentioned clamping mechanism.

[0021] The beneficial effects of this invention are: the clamping mechanism facilitates the fixed installation of the flow equalizer and adapts to different usage scenarios; the blocking surface can prevent the support from slipping due to excessive movement against the external carrier; the clamping mechanism has various structural forms, which can adapt to different types of flow equalizers, making it flexible and highly adaptable; the assembly structure is simple and easy to operate.

[0030] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0031] Example 1

[0032] like Figures 1-4 As shown, a clamping mechanism for an exhaust manifold diffuser includes a clamping plate 51, a connecting rod 52 connected to the clamping plate 51, and a support portion 53. The clamping plate 51 abuts against the diffuser 3. The connecting rod 52 has a driving end 521. The support portion 53 forms an inclined action surface 531 that can abut against an external carrier 6. Applying an external force to the driving end 521 causes the connecting rod 52 to move, and the inclined action surface 531 can move against the external carrier 6, thereby driving the clamping plate 51 to move against the diffuser 3, achieving the purpose of driving the diffuser 3 to move upward or downward.

[0033] In this embodiment, the flow equalizer 3 has an inclined surface 30, and at least a portion of the connecting rod 52 is parallel to the inclined surface 30. Specifically, the inclined surface 30 is located at the bottom of the flow equalizer 3 and is inclined upwards, specifically in the direction of flue gas flow. The connecting rod 52 is inclined as a whole and is nearly parallel to the inclined surface 30.

[0034] At this time, a positioning tooth 314 is provided on the top of the flow equalizer 3, which can be positioned and installed with an external carrier 6. The external carrier 6 can be a wall forming an exhaust channel. The positioning tooth 314 is also inclined, and the inclination direction is the same as the inclination direction of the inclined surface 30. In this embodiment, the positioning tooth 314 abuts against the thickness direction of the wall.

[0035] like Figure 3 As shown, the clamping plate 51 is attached to the inclined surface 30 of the flow equalizer 3 and is integrally connected to the support part 53. A vertical panel 54 is formed between the clamping plate 51 and the support part 53. The vertical panel 54 is parallel to the external carrier 6. The connecting rod 52 passes through the vertical panel 54 and forms a drive end 521 that extends out of the flow equalizer 3. Of course, in other embodiments, the support part 53 may not be integrally connected to the clamping plate 51, but may be connected to the connecting rod 52.

[0036] In this embodiment, the outer wall of the connecting rod 52 has external threads, and a rotating component 522 is threadedly connected to the drive end 521. Applying external force to rotate the rotating component 522 can drive the connecting rod 52 to move relative to the flow equalizer 3. Specifically, the rotating component 522 is a locking screw. When the locking screw is tightened, the connecting rod 52 is pulled towards the exhaust port 11 of the flow equalizer 3, thereby pushing the clamping plate 51 upward to push the flow equalizer 3, so that the positioning teeth 314 at the top of the flow equalizer 3 are firmly engaged with the external carrier 6.

[0037] Of course, in other embodiments, the rotating member 522 may not be provided, and the connecting rod 52 may be pulled outward directly, and the clamping plate 51 may push the flow equalizer 3 upward.

[0038] To prevent the support part 53 from slipping due to excessive movement when it moves against the external carrier 6, the inclined surface 531 of the support part 53 is inclined downward and a blocking surface 532 is formed at the lower end. The blocking surface 532 ensures that the support part 53 is always in contact with the external carrier 6.

[0039] Example 2

[0040] like Figures 5-7 As shown, in this embodiment, the inclined surface 30 is disposed on the top of the flow equalizer 3, and it slopes downward, opposite to the slope direction in Embodiment 1. A stroke groove 55 is formed at the corresponding position of the inclined surface 30, and the stroke groove 55 is also inclined, and in the same slope direction as the inclined surface 30. The positioning teeth 314 are disposed at the bottom of the flow equalizer 3. The connecting rod 52 is also inclined and nearly parallel to the inclined surface 30.

[0041] Part of the clamping plate 51 extends into the stroke groove 55. When the connecting rod 52 drives the clamping plate 51 to move relative to the flow equalizer 3 along the stroke groove 55, the clamping plate 51 presses down on the flow equalizer 3, causing the flow equalizer 3 to move towards the positioning tooth 314.

[0042] In this embodiment, the two ends of the clamping plate 51 are bent to form a locking part 511, which extends into the travel groove 55. In order to facilitate assembly, a widening section 551 is provided at the end of the travel groove 55. The width of the widening section 551 is adapted to the width of the locking part 511, so that the locking part 511 can enter the travel groove 55 through the widening section 551.

[0043] At this time, the inclined surface 531 of the support 53 is inclined upward, and a blocking surface 532 is formed at the lower end. The blocking surface 532 ensures that the support 53 is always in contact with the external carrier 6. The positioning tooth 314 located at the bottom of the flow equalizer 3 is also inclined, and the inclination direction is the same as the inclination direction of the inclined surface 30.

[0044] An external force is applied to drive the connecting rod 52 to move relative to the flow equalizer 3. The clamping plate 51 slides in the stroke groove 55 and pushes the flow equalizer 3 downward, so that the positioning teeth 314 at the bottom of the flow equalizer 3 are firmly engaged with the external carrier 6.

[0045] Example 3

[0046] like Figure 8 As shown, in this embodiment, the bottom of the flow equalizer 3 is horizontal, and the clamping plate 51 is attached to the bottom surface of the flow equalizer 3. Other structures are the same as in Embodiment 1, and will not be described again.

[0047] Example 4

[0048] A valve body includes an exhaust port 11, a valve plate unit 2, and a flow equalizer 3 corresponding to the exhaust port 11, such as... Figure 4 As shown, the flow equalizer 3 has a clamping mechanism with the structure described above. The valve body can be a check valve or a flow equalizer.

[0049] The above specific embodiments are used to explain and illustrate the present invention, but not to limit the present invention. Any modifications and changes made to the present invention within the spirit and scope of the claims shall fall within the protection scope of the present invention.
