Description

Technical Field

[0001] The utility model relates to the technical field of door and window accessories, in particular to a silent block and a transmission component. Background Art

[0002] Door and window accessories are auxiliary components that enable doors and windows to open and close. These accessories include handles, drive housings, locking rods, transmission rods, and lock bases. The handle drives the transmission housing and transmission rods to slide relative to the door and window profiles, and drives the locking rods into and out of the lock bases, enabling the doors and windows to open and close. Because transmission rods are typically long, if there is a gap between the transmission rod and the profile, sliding against the profile can easily produce noise. Utility Model Content

[0003] The purpose of the present utility model is to provide a silent block and a transmission assembly to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The technical solution adopted to solve the above technical problems is: a silent block, installed between the transmission rod and the profile, including: a mounting block, installed on the transmission rod; a silent spring, arranged at the end of the mounting block, the middle part of the silent spring is bent and abuts against the profile, and the silent spring abuts against the transmission rod at one end away from the mounting block, so that the silent spring provides elastic force to press the transmission rod against the side wall of the profile.

[0005] This technical solution has at least the following beneficial effects: the mounting block is mounted on the transmission rod, and the silent spring uses the elastic force generated by its own bending to press the transmission rod against the side wall of the groove, eliminating any gap between the transmission rod and the side wall of the profile. This reduces shaking when the transmission rod slides relative to the profile, thereby reducing noise generation. Furthermore, the mounting block and the silent spring are arranged side by side, with one side of the silent spring contacting the profile and attached to the transmission rod, while the other side is in contact with the transmission rod. This makes the structure of the silent spring and its connection to the mounting block relatively simple and less prone to damage, making it easier to manufacture and use.

[0006] As a further improvement to the above technical solution, a through hole is formed in the middle of the silent spring piece, so that the silent spring piece has a ring-shaped structure, which saves materials, improves the elasticity of the silent spring piece, and reduces production costs.

[0007] As a further improvement of the above technical solution, the silent spring and the mounting block are integrally formed.

[0008] As a further improvement to the above technical solution, both ends of the mounting block are respectively installed with silent springs, thereby improving the stability and balance of both ends of the mounting block.

[0009] As a further improvement of the above technical solution, the mounting block is mounted with a cylinder, and the transmission rod is provided with a mounting hole for the cylinder to be embedded in, thereby improving the connection stability between the mounting block and the transmission rod.

[0010] As a further improvement of the above technical solution, the invention further comprises a mounting cover that is mounted on the mounting block in a snap-fit ​​manner, wherein the mounting cover and the mounting block clamp the transmission rod. The mounting block is mounted on the transmission rod in a snap-fit ​​manner, which facilitates the assembly of the mounting block and the transmission rod.

[0011] As a further improvement to the above technical solution, the mounting block is provided with a connecting hole, and the mounting cover is provided with a connecting post. The connecting post is provided with a cone at one end away from the mounting cover, the diameter of which gradually increases as it moves away from the mounting cover. The connecting hole is provided with a conical surface that matches the cone. The conical structure and the conical surface prevent the connecting post from separating from the connecting hole, thereby ensuring a secure connection between the mounting block and the transmission rod.

[0012] As a further improvement to the above technical solution, a notch is formed on the outer periphery of the cone, and the bottom wall of the notch extends to the connecting column. The notch provides space for the cone to deform, making it easier for the cone to fit into the connecting hole, thereby smoothly connecting the mounting block to the transmission rod.

[0013] A transmission assembly comprises the above-mentioned silent block, the transmission rod and the profile slidably connected to the transmission rod.

[0014] As a further improvement to the above technical solution, the transmission rod is provided with an inner groove for the silent block to be inserted, and the inner groove runs through both ends of the transmission rod. The inner groove space provides more installation space for the silent block, reduces the reserved gap between the transmission rod and the inner wall of the profile, and is suitable for thinner profiles.

[0025] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0026] Reference Figure 1-5 The mute block is used to reduce the noise generated by the shaking when the transmission rod 400 slides relative to the profile 500, so that the sliding process of the transmission rod 400 can achieve a silent effect. The mute block includes a mounting block 100 and a mute spring 200.

[0027] The mounting block 100 is a cubic, sheet-like structure, with a silent spring 200 attached to each of its two opposite ends. The silent spring 200 is bent toward one flat side of the mounting block 100 and then bent again in the opposite direction, forming a V-shaped cross-section. The central portion of the silent spring 200 extends beyond one flat side of the silent spring 200, and the end of the silent spring 200 facing away from the mounting block 100 also extends beyond the other flat side of the silent spring 200.

[0028] When the mute block is installed on the side of the transmission rod 400 close to the profile 500, the raised portion of the middle portion of the mute spring 200 contacts the inner wall of the profile 500, and the end of the mute spring 200 away from the mounting block 100 contacts the side of the transmission rod 400 close to the profile 500. The elastic force generated by the bending of the mute spring 200 causes the side of the transmission rod 400 away from the mute block to contact the inner wall of the profile 500, thereby eliminating the remaining gap between the transmission rod 400 and the profile 500. When the transmission rod 400 slides relative to the profile 500, the transmission rod is less likely to rock back and forth, thereby achieving the effect of reducing noise. Furthermore, the mute spring 200 is provided at both ends of the mounting block 100, that is, a mute block can create two different action points between the transmission rod 400 and the profile 500, better limiting the rocking of the transmission rod 400 and improving the sliding stability of the transmission rod 400.

[0029] The mounting block 100 and the silent spring 200 are integrally formed, ensuring a strong connection between the two and facilitating manufacturing of the silent block. A through-hole 210 is provided in the center of the silent spring 200, with both ends of the through-hole 210 extending through the silent spring 200, giving the silent spring 200 an annular structure. This saves material, reducing production costs, while also enhancing the elastic deformation capability of the silent spring 200.

[0030] A cylinder 110 is provided on one side of the mounting block 100 , and the cylinder 110 and the mounting block 100 are integrally formed.

[0031] A connecting hole 120 with a circular cross-section is defined in the center of the mounting block 100 and is coaxial with the cylindrical body 110. A mounting hole 410 is defined in the transmission rod 400. The diameter of the mounting hole 410 is the same as the outer diameter of the cylindrical body 110, and the diameter of the connecting hole 120 is the same as the inner diameter of the cylindrical body 110. The height of the cylindrical body 110 is equal to or less than the depth of the mounting hole 410. This allows the cylindrical body 110 to be embedded in the mounting hole 410, thereby enhancing the connection strength between the mounting block 100 and the transmission rod 400.

[0032] The mute block further includes a mounting cover 300, the diameter of which is larger than the diameter of the mounting hole 410. A connecting post 310 is provided on one side of the mounting cover 300, and the connecting post 310 is integrally provided with the mounting cover 300.

[0033] A cone 320 is integrally formed on the side of the connecting column 310 away from the mounting cover 300. The diameter of the end of the cone 320 connected to the connecting column 310 is the same as the diameter of the connecting column 310. The diameter of the cone 320 gradually increases in the direction away from the connecting column 310. The connecting hole 120 is provided with a conical surface 121 at the end away from the cylinder 110 embedded in the mounting hole 410. The conical surface 121 is adapted to fit the outer taper of the cone 320.

[0034] The connecting post 310 and cone 320 are both hollow structures. A notch 321 is defined on both sides of the end face of the cone 320 facing away from the connecting post 310. The bottom wall of the notch 321 is a circular arc surface that extends to the middle of the connecting post 310. The connecting post 310 and cone 320 are embedded in the connecting hole 120 by elastic deformation. The conical surface 121 restrains the cone 320, allowing the mounting cover 300 and the mounting block 100 to clamp the transmission rod 400, completing the assembly between the mounting block 100 and the transmission rod 400.

[0035] In other embodiments, the snap-fit ​​connection between the mounting cover 300 and the mounting block can be achieved by providing a raised hook on the inner sidewall of the connecting hole 120 and providing a slot on the connecting post 310 for the hook to engage with. By inserting the connecting post 310 into the connecting hole 120, the snap-fit ​​connection between the mounting cover 300 and the mounting block 100 can be achieved. In other embodiments, the mounting block 100 can also be directly mounted on the transmission rod 400 using rivets or bolts.

[0036] This embodiment also discloses a transmission assembly, comprising the aforementioned silent blocks, a transmission rod 400, and a profile 500. Two silent blocks are mounted at either end of the transmission rod 400, and the transmission rod 400 is slidably connected to the profile 500. Specifically, a T-slot 510 having a T-shaped cross section is provided on one side of the profile 500, giving the profile 500 a C-shaped cross section. The transmission rod 400 has a T-shaped cross section that matches the profile 500, allowing the transmission rod 400 to slide and fit within the T-slot 510. A predetermined gap is provided between one side of the transmission rod 400 and the bottom wall of the T-slot 510 to facilitate insertion of the transmission rod 400 within the T-slot 510. Under the action of the silent blocks, the transmission rod 400 contacts the inner sidewall of the T-slot 510 near the notch, thereby preventing the transmission rod 400 from shaking when sliding within the profile 500, achieving a silent effect.

[0037] An inner groove 420 is formed on a side of the transmission rod 400 close to the profile 500 , and two ends of the inner groove 420 pass through two ends of the transmission rod 400 respectively.

[0038] The width of the inner groove 420 is the same as or slightly larger than the width of the silent block. When assembling the silent block and the transmission rod 400, the mounting block 100 can be embedded in the inner groove 420, improving the stability of the connection between the silent block and the transmission rod 400. At the same time, the space in the inner groove 420 can accommodate the silent block, reducing the remaining gap between the transmission rod 400 and the profile 500 required for installing the silent block, and adapting to the thinner profile 500.

[0039] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
