Description

Technical Field

[0001] This invention relates to the field of door and window handle technology, and in particular to a door and window handle that can make a sound. Background Technology

[0002] Traditional door and window handles contain a transmission gear and a positioning component. The positioning component typically uses a spring to press a steel ball. When the handle is turned once, the spring presses the steel ball into the corresponding groove of the transmission gear, so that the handle stops at one of the four positions of 0°, 90°, 180° and 270° when the door or window is opened.

[0003] As people aspire to a better life, new demands are being placed on door and window handles, with a desire for a pleasant mechanical sound when operating them for a better user experience. In existing technology, traditional door and window handles feature multiple evenly distributed toothed grooves on the transmission gear. When the transmission gear, connected to the handle, rotates, steel balls collide with these grooves, producing sound. This design relies primarily on the rapid rotation of the gear and the collision of the steel balls to generate sound. Operation requires quick rotation of the handle; slow rotation produces no sound because, during slow rotation, the steel balls, under the pressure of a spring, slide along the sidewall of the gear teeth into the grooves, resulting in little or no sound when the steel balls collide with the grooves. However, once the handle is installed behind the door or window, the door and window transmission system limits rapid rotation, and users are unlikely to operate the handle at extremely high speeds, resulting in a poor mechanical sound.

[0004] It is evident that existing technologies still need improvement and enhancement. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a door and window handle that can make a sound, in order to solve the technical problem of poor mechanical noise when the handle is turned.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A door and window handle capable of producing a sound includes a metal base, a spring seat, a transmission gear, a handle, and a steel ball. One side of the metal base has a first receiving cavity and several second receiving cavities communicating with the first receiving cavity. The other side of the metal base has a removable cover plate. The spring seat is located within the first receiving cavity and has a baffle plate covering the surface of the second receiving cavities. The transmission gear is rotatably connected to the spring seat and has a connecting shaft extending towards the cover plate. The handle is mounted on the connecting shaft, and a clamping assembly is provided between the handle and the cover plate. Each second receiving cavity has a stop block on both sides near the end of the first receiving cavity. A steel ball is correspondingly located within one second receiving cavity, and a first spring is provided between the steel ball and the second receiving cavity. When the transmission gear rotates, the steel ball creates a gap with one of the stop blocks and then collides with the stop block, producing a mechanical sound.

[0008] Furthermore, there are two second receiving cavities, and the two second receiving cavities are arranged symmetrically at 180°.

[0009] Furthermore, the outer circumference of the transmission gear is provided with four evenly distributed first tooth grooves, and a number of evenly distributed second tooth grooves are provided between two adjacent first tooth grooves, the depth of the first tooth grooves being deeper than the depth of the second tooth grooves.

[0010] Furthermore, the metal base and the several impact blocks are integrally formed.

[0011] Furthermore, the two sides of the two impact blocks located in the same second receiving cavity are inclined towards the center in the direction of the first receiving cavity.

[0012] Furthermore, the two corresponding sides of the two impact blocks located in the same second receiving cavity are parallel to each other.

[0013] Furthermore, the spring seat also includes a mounting plate, a sleeve perpendicularly disposed on one side of the mounting plate, and an arc-shaped sidewall perpendicularly disposed on the other side of the mounting plate. A baffle plate is perpendicularly disposed on the arc-shaped sidewall, and an avoidance hole corresponding to the second receiving cavity is opened on the arc-shaped sidewall; the connecting shaft is rotatably connected to the sleeve.

[0014] Furthermore, the shielding plate is provided with two side plates for defining the position of the first spring.

[0015] Furthermore, the metal base is provided with a boss, and the cover plate has a first groove that matches the boss, with a chamfer on the top edge of the first groove.

[0016] Furthermore, the metal base is provided with a shaft extending toward the handle, and the clamping assembly includes a washer disposed between the shaft and the handle and a second spring sleeved on the shaft, one end of the second spring abutting against the cover plate and the other end abutting against the handle.

[0017] Beneficial effects: The metal base is provided with a first receiving cavity and a second receiving cavity, and the second receiving cavity is provided with two impact blocks. Under the action of the first spring, the steel ball is pressed against the transmission gear. During the process of driving the transmission gear to rotate by turning the handle, the teeth of the transmission gear press against the steel ball, causing the steel ball to move towards the impact block on one side. A gap is created between the steel ball and the impact block on the other side. When the tooth groove of the transmission gear faces the steel ball, the steel ball instantly hits the impact block on the other side in the opposite direction, thereby producing a mechanical sound. Compared with the existing technology, the transmission gear can be driven to rotate by turning the handle quickly or slowly, so that the steel ball creates a gap with an impact block and then instantly hits the impact block, thereby producing a crisp mechanical sound, and the mechanical sound effect is better.

Detailed Implementation

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

[0028] Please see Figure 1-8 This invention provides a door and window handle that can produce a sound, including a metal base 1, a spring seat 2, a transmission gear 3, a handle 4, and a steel ball 5. One side of the metal base 1 is provided with a first receiving cavity 11 and several second receiving cavities 12 communicating with the first receiving cavity 11. The other side of the metal base 1 is provided with a detachable cover plate 6. The spring seat 2 is located inside the first receiving cavity 11, and a baffle plate 21 covering the surface of the second receiving cavities 12 is provided on the spring seat 2. The transmission gear 3 is rotatably connected to the spring seat 2, and a connecting shaft 31 extending towards the cover plate 6 is provided on the transmission gear 3. The handle 4 is mounted on the connecting shaft 31, and a clamping assembly 7 is provided between the handle 4 and the cover plate 6. Each second receiving cavity 12 has a stop block 8 on both sides near the end of the first receiving cavity 11. A steel ball 5 is correspondingly located in one second receiving cavity 12, and a first spring 9 is provided between the steel ball 5 and the second receiving cavity 12. When the transmission gear 3 rotates, the steel ball 5 creates a gap with one of the stop blocks 8, and then collides with the stop block 8 to produce a mechanical sound.

[0029] In the installed state, the connecting shaft 31 passes through the spring seat 2, the metal base 1, and the cover plate 6 in sequence and connects to the handle 4, so that the transmission gear 3 presses and fixes the spring seat 2 in the first receiving cavity 11; and the second receiving cavity 12 cooperates with the baffle plate 21 to form an installation space for accommodating the steel ball 5 and the first spring 9, so as to prevent the steel ball 5 and the first spring 9 from coming out.

[0030] In use, the metal base 1 is installed on the profile of the door or window; such as Figure 3As shown, turning the handle 4 clockwise (clockwise is the direction of the arrow in the diagram) causes the connecting shaft 31 to rotate, making the transmission gear 3 rotate clockwise around the axis of the connecting shaft 31. The steel ball 5 presses against the transmission gear 3 under the action of the first spring 9. When the teeth of the transmission gear 3 press against the steel ball 5, since the transmission gear 3 rotates clockwise, the steel ball 5 moves towards the first spring 9 and moves towards the impact block 8 on one side, creating a gap between the steel ball 5 and the impact block 8 on the other side, compressing the first spring 9. As the transmission gear 3 continues to rotate, when its tooth grooves face the steel ball 5, under the elastic force of the first spring 9, the steel ball 5 will instantly hit the impact block 8 on the other side in the opposite direction, producing a mechanical sound when the steel ball 5 collides with the impact block 8. Similarly, turning the handle 4 counterclockwise will also cause the steel ball 5 to collide with the impact block 8, which has a gap with the steel ball 5, thus producing a mechanical sound. By rotating the transmission gear 3, a gap is created between the steel ball 5 and a striking block 8. When the steel ball 5 enters the tooth groove of the transmission gear 3, the steel ball 5 collides with the striking block 8, so as to ensure that mechanical sound can be produced when the handle 4 is rotated quickly or slowly, and the mechanical sound effect is good.

[0031] In a preferred embodiment, see [reference] Figure 3 There are two second receiving cavities 12, and the two second receiving cavities 12 are arranged symmetrically at 180°, so that the transmission gear 3 is subjected to uniform force.

[0032] Further, see Figure 3 The outer circumference of the transmission gear 3 is provided with four evenly distributed first tooth grooves 32, and a plurality of evenly distributed second tooth grooves 33 are provided between two adjacent first tooth grooves 32. The depth of the first tooth grooves 32 is deeper than the depth of the second tooth grooves 33. With four deeper first tooth grooves 32, the steel ball 5 is pressed against the first tooth grooves 32 under the action of the first spring 9, which plays a positioning role for the transmission gear 3, so as to position the handle 4 at four positions: 0°, 90°, 180°, and 270°. In addition, with multiple first tooth grooves 32 and second tooth grooves 33, multiple mechanical sounds can be emitted when the handle 4 is turned to meet the user's needs.

[0033] In a preferred embodiment, the metal base 1 and the plurality of impact blocks 8 are integrally formed, which can improve the processing accuracy of the metal base 1 and the impact blocks 8, and ensure the installation stability of the impact blocks 8, so as to avoid the impact blocks 8 from loosening and affecting the mechanical sound effect.

[0034] In this embodiment, the structure of the two sides of the two impact blocks 8 located in the same second receiving cavity 12 has the following two implementation methods.

[0035] First implementation method: such as Figure 4As shown, the two opposing sides of the two impact blocks 8 located in the same second receiving cavity 12 are inclined towards the center of the first receiving cavity 11. With this arrangement, a groove that gradually narrows towards the first receiving cavity 11 is formed between the two impact blocks 8. When the tooth groove of the transmission gear 3 faces the steel ball 5, under the elastic force of the first spring 9, the steel ball 5 is located at the narrowest position between the two impact blocks 8, which positions the steel ball 5 and further positions the transmission gear 3 effectively. When the teeth of the transmission gear 3 gradually press against the steel ball 5, the steel ball 5 moves towards the first spring 9, creating a gap between it and one of the impact blocks 8. This allows the steel ball 5 to instantly bounce towards the impact block 8 when the tooth groove of the transmission gear 3 turns towards it, colliding with the impact block 8 and producing a crisp mechanical sound. In this embodiment, the above-described implementation method is preferred.

[0036] The second implementation method: as follows Figure 5 As shown, the two sides of the two impact blocks 8 located in the same second receiving cavity 12 are parallel to each other. The slot between the two impact blocks 8 is clearance-fitted with the steel ball 5. When the transmission gear 3 rotates, the teeth of the transmission gear 3 act on the steel ball 5, causing the steel ball 5 to deflect towards one side of the impact block 8. At this time, there is a gap between the steel ball 5 and the other side impact block 8. When the tooth groove of the transmission gear 3 faces the steel ball 5, the steel ball 5 collides with the other side impact block 8 and produces a crisp mechanical sound.

[0037] In a preferred embodiment, see [reference] Figure 2 , 7 The spring seat 2 further includes a mounting plate 22, a sleeve 23 perpendicularly disposed on one side of the mounting plate 22, and an arc-shaped sidewall 24 perpendicularly disposed on the other side of the mounting plate 22. The arc-shaped sidewall 24 matches the sidewall of the first receiving cavity 11, allowing the spring seat 2 to be installed in the first receiving cavity 11. A baffle plate 21 is perpendicularly disposed on the arc-shaped sidewall 24, and the arc-shaped sidewall 24 has a clearance hole 25 corresponding to the second receiving cavity 12. The connecting shaft 31 is rotatably connected to the sleeve 23. By setting the sleeve 23, the contact area between the connecting shaft 31 and the spring seat 2 is increased, thereby ensuring the stability of the installation of the transmission gear 3. Since the mounting plate 22 is located between the transmission gear 3 and the first receiving cavity 11, the spring seat 2 is installed by pressing the spring seat 2 with the transmission gear 3. The installation method is simple and the structure is compact.

[0038] The steel ball 5 and the impact block 8 extend to the clearance hole 25 to avoid positional interference between the steel ball 5 and the impact block 8 and the spring seat 2, which would affect the mechanical sound effect.

[0039] Further, see Figure 7The baffle plate 21 is provided with two side plates 26 for limiting the position of the first spring 9, ensuring that the first spring 9 is compressed and extended along its length direction; in addition, the bottom of the side plate 26 abuts against the bottom of the second receiving cavity 12, so that the side plate 26 supports the baffle plate 21, further improving the stability and structural strength of the spring seat 2 installation.

[0040] In a preferred embodiment, see [reference] Figure 2 , 8 The metal base 1 has a boss 13, and the cover plate 6 has a first groove 61 that matches the boss 13. Under the action of the clamping assembly 7, the cover plate 6 covers the metal base 1 to cover the mounting holes on the metal base 1 for connection with door and window profiles, improving the aesthetics of the handle. Furthermore, the cooperation between the boss 13 and the first groove 61 prevents the cover plate 6 from shifting position. The top edge of the first groove 61 has a chamfer 62. When the cover plate 6 is opened away from the metal base 1 and rotated at an angle, the chamfer 62 facilitates the first groove 61 disengaging from the boss 13. After the cover plate 6 is rotated, the mounting holes on the metal base 1 are exposed, greatly facilitating the user's installation of the metal base 1. In addition, when the cover plate 6 is closed, the chamfer 62 acts as a guide, making it easier for the boss 13 to engage with the first groove 61.

[0041] Further, see Figure 8 The metal base 1 has recesses 15 at the top and bottom, which facilitates the user's fingers to contact the cover plate 6 through the recesses 15, thereby making it easier to open the cover plate 6.

[0042] In a preferred embodiment, see [reference] Figure 2 , 6 8. The metal base 1 has a shaft portion 14 extending towards the handle 4. The pressing assembly 7 includes a washer 71 disposed between the shaft portion 14 and the handle 4 and a second spring 72 sleeved on the shaft portion 14. One end of the second spring 72 abuts against the cover plate 6, and the other end abuts against the handle 4. Under the elastic force of the second spring 72, the cover plate 6 is always pressed tightly against the metal base 1. Specifically, the handle 4 has a third receiving cavity 41. One end of the washer 71 and the second spring 72 are located in the third receiving cavity 41, which serves to cover and thus improve the appearance of the handle.

[0043] Furthermore, the connecting shaft 31 is provided with an insertion part 34, and the handle 4 has a matching insertion hole 42. The connecting shaft 31 is connected to the handle 4 by screws. Specifically, the insertion part 34 has a hexagonal prism structure, and one side wall of the insertion part 34 has a second groove. The insertion hole 42 has a protrusion that mates with the second groove. The engagement of the hexagonal prism structure insertion part 34 with the insertion hole 42 ensures that the handle 4 and the transmission gear 3 rotate synchronously. The engagement of the second groove and the protrusion provides guidance for the installation of the handle 4 and the transmission gear 3, making it easier for the user to install the handle.

[0044] It is understood that those skilled in the art can make equivalent substitutions or changes to the technical solution and inventive concept of the present invention, and all such changes or substitutions should fall within the protection scope of the present invention.
