Description

Technical Field

[0001] This utility model relates to the technical field of door and window hardware accessories, specifically to a silent handle with roller contact. Background Technology

[0002] As one of the main driving components for convenient opening and closing of doors and windows, the handle is generally connected to a lock or a similar structure. This allows the door or window to be opened by mechanically opening the latch or bolt. However, traditional handles use steel balls to limit the main shaft. Because the contact surface of the steel balls is small, there is a tendency for gaps to form between them and the main shaft. This causes a metallic clanging sound as the handle rotates the main shaft due to the movement of the steel balls. Summary of the Invention

[0003] In order to solve one or more technical problems existing in the prior art, the purpose of this application is to provide a silent handle with roller contact, which effectively avoids the problem of existing handles making noise due to metal collision during rotation, so that the handle can rotate without noise.

[0004] To solve the aforementioned technical problems, this application adopts the following technical solution:

[0005] A silent handle with roller contact includes a base, a main shaft disposed within the base, a handle disposed on the base and fixedly connected to the main shaft, a support spring disposed between the base and the handle, and a square steel disposed at the inner end of the main shaft. The rotation of the handle synchronously drives the rotation of the main shaft and the square steel. The outer ring of the main shaft is provided with at least two limiting posts, and the main shaft is provided with several arc-shaped grooves. One side of the limiting post slides into the groove for relative positioning. The base is provided with a sliding groove for the limiting post to slide back and forth. A clamping spring is provided in the sliding groove. One side of the limiting post is tightly pressed against the side of the main shaft during rotation by the clamping spring.

[0006] Preferably, the limiting post adopts a steel column roller structure, and a steel column roller is symmetrically provided on both sides of the main shaft.

[0007] Preferably, it also includes a connector, which includes a connecting ring sleeved on the main shaft and a U-shaped storage groove surrounding the connecting ring. The bottom of the U-shaped storage groove is provided with a support plate, and the top of the U-shaped storage groove is provided with a limiting plate connected to the connecting ring on one side. The U-shaped storage groove is located in the slide groove. The bottom of the tightening spring is supported and limited by the support plate, and both ends of the steel column roller are limited by the limiting plate and the support plate.

[0008] Preferably, the U-shaped storage groove is symmetrically arranged on both sides of the connector, the contact surface between the U-shaped storage groove and the slide is a Y-shaped structure, and the slide is inclinedly arranged in the base.

[0009] Preferably, the handle has a protective cover on its outer side, and the base has a face cover on its outer side.

[0010] Preferably, the square steel is provided with an outwardly protruding limiting ring.

[0011] Preferably, the spindle and the handle are fixed together by screws.

[0012] Preferably, a washer is provided between the spindle and the handle.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] The structure installed in the base to limit the left and right movement of the main shaft uses a combination of clamping springs and limiting posts. This ensures that during the rotation and opening / closing of the handle, each limiting post is always tightly pressed against the side of the main shaft by the clamping spring, thus achieving a silent rotation of the handle. This avoids the problem of existing handles making noise due to metal collisions during rotation, resulting in a better handle feel and no abnormal noise when opening and closing.

[0018] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0019] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0020] The terms "first," "second," etc., used in this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class, without limiting the number of objects; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0021] like Figure 1 and Figure 2 As shown, a silent handle with roller contact includes a base 7, a main shaft 6 disposed within the base 7, a handle 11 disposed on the base 7 and fixedly connected to the main shaft 6, a support spring 10 disposed between the base 7 and the handle 11, and a square steel 1 disposed at the inner end of the main shaft 6. The rotation of the handle 11 synchronously drives the rotation of the main shaft 6 and the square steel 1. The outer ring of the main shaft 6 is provided with at least two limiting posts 15, and the main shaft 6 is provided with several arc-shaped grooves 5. One side of the limiting post 15 slides into the groove 5 for relative positioning. The base 7 is provided with a sliding groove 13 for the limiting post 15 to slide back and forth. A clamping spring 16 is provided in the sliding groove 13. One side of the limiting post 15 is tightly pressed and adhered to the side of the main shaft 6 during rotation by the clamping spring 16.

[0022] The structure that limits the left and right movement of the main shaft 6 within the base 7 uses a combination of a clamping spring 16 and a limiting post 15. This ensures that during the rotation and opening / closing of the handle via the handle 11, each limiting post 15 is always tightly pressed against the side of the main shaft 6 by the clamping spring 16, resulting in a silent rotation of the handle. This avoids the problem of noise caused by metal collisions during the rotation of existing handles, making the handle feel better and eliminating any abnormal noise during opening and closing.

[0023] A further improvement is made in that the limiting post 15 adopts a steel column roller structure, and the main shaft 6 is provided with a steel column roller symmetrically on both sides.

[0024] The limit post 15 adopts a cylindrical steel roller structure, which has better wear resistance and longer service life during use.

[0025] A further improvement includes a connector 4, which includes a connecting ring 3 sleeved on the main shaft 6 and a U-shaped storage groove 17 surrounding the connecting ring 3. The bottom of the U-shaped storage groove 17 is provided with a support plate 19, and the top of the U-shaped storage groove 17 is provided with a limiting plate 18 connected to the connecting ring 3 on one side. The U-shaped storage groove 17 is located in the slide groove 13. The bottom of the top spring 16 is supported and limited by the support plate 19, and both ends of the steel column roller are limited by the limiting plate 18 and the support plate 19.

[0026] When assembling the limiting post 15 and the clamping spring 16, a connector 4 is added between the main shaft 6 and the base 7. The connector 4 is typically made of plastic and is radially positioned around the main shaft 6 via a connecting ring 3. The clamping spring 16 is installed inside the U-shaped storage groove 17, and its bottom is supported and limited by a support plate 19, effectively limiting its position and making assembly easier. Simultaneously, a limiting plate 18 is formed at the top of the U-shaped storage groove 17 near the connection point of the connecting ring 3. This plate provides relative stability to the connector 4 and limits the top of the limiting post 15, preventing it from sliding upwards during use. Combined with the support plate 19, the two ends of the limiting post 15 are effectively limited by the limiting plate 18 and the support plate 19. The length of the limiting plate 18 only needs to be greater than the extension range of the limiting post 15, effectively reducing the weight of the connector 4.

[0027] A further improvement is made in that the U-shaped storage groove 17 is symmetrically arranged on both sides of the connector 4, the contact surface of the U-shaped storage groove 17 and the slide groove 13 is a Y-shaped structure, and the slide groove 13 is inclinedly arranged in the base 7.

[0028] The slide groove 13 is installed at an angle into the bottom of the base 7, which allows the slide groove 13 to be longer when the length of the base 7 is fixed. At the same time, the contact surface between the U-shaped storage groove 17 and the slide groove 13 is Y-shaped, which allows for better positioning after they are installed.

[0029] A further improvement is that a protective cover 12 is provided on the outside of the handle 11, and a face cover 8 is provided on the outside of the base 7.

[0030] The protective cover 12 makes the handhold area of ​​the handle 11 more comfortable, and it can also be customized according to different preferences, effectively solving the problem of the monotonous shape of the existing handle 11 and making the handle more aesthetically pleasing. At the same time, the cover 8 can cover the mounting holes of the screws 14 after the base 7 is fixed, which is more aesthetically pleasing.

[0031] A further improvement is that the square steel 1 is provided with an outwardly protruding limiting ring 2; the main shaft 6 and the handle 11 are fixed together by screws 14.

[0032] When one end of the square steel 1 is inserted into the spindle 6, the depth of the insertion part can be precisely controlled by the limiting ring 2, so that the square steel 1 no longer needs to be inserted to the bottom for positioning, and the length of the insertion part can be shorter; the screw 14 is inserted into the spindle 6 through the hole of the square steel 1 and then connected to the handle 11, which is more concealed after installation.

[0033] A further improvement is that a washer 9 is provided between the spindle 6 and the handle 11.

[0034] The washer 9 serves to seal and limit movement, preventing the contact surfaces of the spindle 6 and handle 11 from loosening due to wear, and also preventing abnormal noise.

[0035] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
