Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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.

[0036] It should be understood that, when used in this specification and the appended claims, the terms "comprising" and "including" indicate the presence of the described features, integrals, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or collections thereof.

[0037] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0038] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0039] Example 1:

[0040] Please see Figure 1This embodiment provides a lock cylinder cover mounting structure, including: a lock body 1, a lock cylinder 2, a connector 3, and two lock cylinder covers 4. The lock body 1 is mounted on a door leaf 5. The lock cylinder 2 is detachably mounted on the lock body 1 via the connector 3. The two lock cylinder covers 4 are correspondingly inserted into the end positions of the lock cylinder 2 and installed in lock cylinder cover mounting holes 6. When the connector 3 tightens the lock cylinder 2, the lock cylinder 2 pulls the two lock cylinder covers 4 along the tension direction of the connector 3 to press against the lock cylinder cover mounting holes 6. The lock cylinder covers 4 can accommodate the end portion of the lock cylinder 2. When the lock cylinder 2 undergoes radial displacement, it can drive the two lock cylinder covers 4 to move synchronously until they press against the inner wall of the lock cylinder cover mounting holes 6 to achieve a stable installation.

[0041] Specifically, the door leaf 5 is provided with a receiving part 7 and a handle cover mounting hole 8 communicating with the receiving part 7, and the lock body 1 is installed in the receiving part 7.

[0042] Please see Figure 2 and Figure 3 In this embodiment, a preferred structure for the lock cylinder cover 4 is also provided. The lock cylinder cover 4 is provided with a placement portion 9, and the placement portion 9 is provided with a mounting member 10. The mounting member 10 is an elastic member, and the lock cylinder cover 4 is centrally positioned on the lock cylinder cover mounting hole 6 through the elastic member. The mounting member 10 is installed inside the placement portion 9, and the lock cylinder cover 4 is centrally mounted on the lock cylinder cover mounting hole 6 through an interference fit with the mounting member 10. Furthermore, the mounting member 10 is a rubber ring, and the placement portion 9 is provided on the outer surface of the lock cylinder cover 4. The rubber ring can, on the one hand, ensure that the lock cylinder cover 4 is centrally positioned in the lock cylinder cover mounting hole 6 through the support of the rubber ring, and on the other hand, the rubber ring makes the installation and removal of the lock cylinder cover 4 more convenient.

[0043] In this embodiment, multiple mounting parts 10 are provided, and multiple corresponding placement parts 9 are provided. The lock cylinder cover 4 abuts against the inner wall of the lock cylinder cover mounting hole 6 through multiple mounting parts 10 to increase friction and ensure the stability of the installation, while achieving centered installation at the center position of the lock cylinder cover mounting hole 6.

[0044] In this embodiment, the part of the lock cylinder cover 4 that connects to the lock cylinder cover mounting hole 6 has the same shape as the lock cylinder cover mounting hole 6. For example, the part of the lock cylinder cover 4 that connects to the lock cylinder cover mounting hole 6 and the lock cylinder cover mounting hole 6 can be square, triangular or other regular shapes, or even irregular shapes. Preferably, the lock cylinder cover mounting hole 6 is also circular. The circular shape of the lock cylinder cover mounting hole 6 can reduce its processing technology and improve the installation efficiency of the entire product. Thus, during installation, unlike the prior art which requires processing a gourd-shaped hole to accommodate the lock cylinder, the installer in this embodiment only needs to process a circular hole, which is simple and quick.

[0045] Please see Figure 4-7In this embodiment, another preferred implementation structure of the lock cylinder cover 4 is also provided. The lock cylinder cover 4 is provided with a mounting member 10, and the lock cylinder cover 4 is tightly abutted against the lock cylinder 2 through the mounting member 10.

[0046] Furthermore, the lock cylinder cover 4 is provided with two mounting parts 10, which are arranged opposite to each other. The lock cylinder cover 4 is pressed against both sides of the lock cylinder 2 by the two mounting parts 10 to realize that the lock cylinder cover 4 is centered in the middle position of the lock cylinder 2. The arrangement of the two mounting parts 10 facilitates the centered positioning of the lock cylinder cover 4 relative to the lock cylinder 2 and the lock cylinder cover mounting hole 6, and also plays a role in assisting the installation of the lock cylinder cover 4.

[0047] Please see Figure 5 The lock cylinder 2 includes a lock cylinder body 11 and a fixing part 12 fixedly connected to the lock cylinder body 11. The fixing part 12 is detachably connected to the lock body 1 through a connector 3, and the mounting part 10 abuts against the fixing part 12. The design of the fixing part 12 can ensure a stable connection between the lock cylinder 2 and the lock body 1, and can also withstand the deformation and friction of the mounting part 10 during the contact process, thereby avoiding damage to the lock cylinder body 11 caused by the deformation and friction of the mounting part 10 when it contacts the lock cylinder body 11.

[0048] For further details, please refer to Figure 6 and Figure 7 The mounting component 10 includes a mounting section 13 and a retaining section 14 fixedly connected to the mounting section 13. A protrusion 15 is provided on the side of the lock cylinder cover 4 near the lock cylinder 2. The mounting section 13 is sleeved on the protrusion 15. The lock cylinder cover 4 is pressed against one side of the fixing part 12 by the retaining section 14 to achieve a centered position on the lock cylinder cover mounting hole 6.

[0049] In this embodiment, the structure of the mounting section 13 sleeved on the protrusion 15 can achieve a stable connection between the mounting member 10 and the lock cylinder cover 4, avoiding the problem of the mounting member 10 and the lock cylinder cover 4 being separated by external force during the process of installing the lock cylinder cover 4 into the lock cylinder cover mounting hole 6, thereby avoiding the problem of the lock cylinder cover 4 not being centered. On the other hand, the structure of the mounting section 13 sleeved on the protrusion 15 can achieve a detachable connection between the mounting member 10 and the lock cylinder cover 4, realizing convenient disassembly and assembly between the mounting member 10 and the lock cylinder cover 4.

[0050] Furthermore, the part of the locking section 14 that contacts the fixing part 12 is provided with an arc or a chamfer. The arc or chamfer design can increase the contact area between the locking section 14 and the fixing part 12, thereby reducing the pressure between the locking section 14 and the fixing part 12, which can reduce the frictional damage to the fixing part 12 caused by the elastic force of the mounting part 10, and improve the service life of the lock cylinder 2.

[0051] In this embodiment, a chamfer is provided at the connection between the mounting section 13 and the clamping section 14. The chamfer can improve the bending moment strength of the connection between the mounting section 13 and the clamping section 14, enhance the stability and durability of the connection, and at the same time, the chamfer design can also reduce stress concentration, reduce the risk of fatigue cracks in the connection, and improve the service life of the product.

[0052] In this embodiment, the retaining section 14 adopts an arc-shaped spring structure design. The arc-shaped spring structure design allows the retaining section 14 to deform under the condition that the gap between the lock cylinder cover 4 and the lock cylinder 2 is limited during the installation of the lock cylinder cover 4 to the lock cylinder 2, thereby achieving a tight contact with the lock cylinder 2 and realizing the connection between the lock cylinder cover 4 and the lock cylinder 2.

[0053] It should be noted that the structure of the mounting component 10 in this embodiment can also be used for the locking of the lock cylinder cover 4 and the door leaf 5. Specifically, the protrusion 15 is set on the lock cylinder cover 4 near the lock cylinder cover mounting hole 6, and then the locking section 14 is provided to compress and deform to achieve the centering of the lock cylinder cover 4 and the lock cylinder cover mounting hole 6.

[0054] Please see Figure 8 In this embodiment, another preferred implementation structure of the lock cylinder cover 4 is also provided. A mounting member 10 is provided between the lock cylinder cover 4 and the lock cylinder 2. The mounting member 10 includes a first magnetic member 16 and a second magnetic member 17. The first magnetic member 16 is mounted on the lock cylinder 2, and the second magnetic member 17 is mounted on the lock cylinder cover 4. The first magnetic member 16 and the second magnetic member 17 attract each other.

[0055] This magnetic structure increases the installation stability of the lock cylinder cover 4, preventing the lock cylinder 2 from weakening its contact with the lock cylinder cover 4 when the door leaf 5 vibrates, thus preventing the lock cylinder cover 4 from becoming loose.

[0056] Furthermore, to enhance the stability of its structure, multiple first magnetic accommodating elements 16 and multiple second magnetic accommodating elements 17 are provided. Multiple first magnetic accommodating elements 16 are installed on the lock cylinder 2, and multiple second magnetic accommodating elements 17 are installed on the lock cylinder cover 4. The lock cylinder cover 4 is installed on the lock cylinder cover mounting hole 6 through the magnetic attraction between the first magnetic accommodating elements 16 and the corresponding second magnetic accommodating elements 17. The structural design of multiple first magnetic accommodating elements 16 and multiple second magnetic accommodating elements 17 can enhance the magnetic attraction force between the lock cylinder cover 4 and the lock cylinder 2. By increasing the stability of the connection between the lock cylinder cover 4 and the lock cylinder 2, the installation of the lock cylinder cover 4 is more stable.

[0057] The magnetic attraction structure can also be set between the lock cylinder cover 4 and the lock body 1. The lock cylinder cover 4 can be installed on the lock cylinder cover mounting hole 6 through the connection between the lock cylinder cover 4 and the lock body 1. Specifically, the first magnetic attraction member 16 is installed on the lock body 1, and the second magnetic attraction member 17 is installed on the lock cylinder cover 4. The lock cylinder cover 4 is centered on the lock cylinder cover mounting hole 6 through the magnetic attraction between the first magnetic attraction member 16 and the second magnetic attraction member 17.

[0058] The magnetic structure can also be set between the lock cylinder cover 4 and the door leaf 5. The lock cylinder cover 4 can be installed on the lock cylinder cover mounting hole 6 by connecting the lock cylinder cover 4 and the door leaf 5. Specifically, the first magnetic component 16 is installed on the door leaf 5, and the second magnetic component 17 is installed on the lock cylinder cover 4. The lock cylinder cover 4 is centered on the lock cylinder cover mounting hole 6 by the magnetic attraction between the first magnetic component 16 and the second magnetic component 17.

[0059] Example 2:

[0060] Please see Figure 2-9 This embodiment provides a door and window lock installation structure, including the lock cylinder cover installation structure described in the above embodiment, and also includes two handles 18, a connecting shaft 19, and a handle cover 20. A rotating wheel portion 21 is provided on the lock body 1. The connecting shaft 19 passes through the rotating wheel portion 21, and its two ends are respectively connected to the two handles 18 via fasteners 22. The connection position between the connecting shaft 19 and the handles 18 is adjustable along the length of the connecting shaft 19. The handle cover 20 is disposed between the handle and the door leaf 5, with its two ends abutting against the handles 18 and the door leaf 5 respectively. After installation, since the handles 18 can accommodate a certain length of the connecting shaft 19, the connection position between the connecting shaft 19 and the handles 18 on both sides can be adaptively adjusted according to the different thicknesses of the door leaf 5. The length of the connecting shaft 19 compensates for changes in the thickness of the door leaf 5. Simultaneously, after the handles 18 on both sides are installed, they clamp the corresponding handle cover 20 onto the door leaf 5, forming a compact overall structure.

[0061] In this embodiment, a deformable portion 23 is provided on the side wall of the handle cover 20 so that the handle cover 20 is centrally located in the handle cover mounting hole 8 of the door leaf 5. Furthermore, the deformable portion 23 can be an independently provided elastic element, which abuts against the inner wall of the handle cover mounting hole 8, allowing the handle cover 20 to be centrally located and reducing friction with the connecting shaft 19; the deformable portion 23 can also be integrally provided with the handle cover 20, abutting against the inner wall of the handle cover mounting hole 8 through its own deformation, similarly allowing the handle cover 20 to be centrally located.

[0062] To address the shortcomings of existing technology where the gap between the connecting shaft 19 and the lock body 1 causes the handle 18 to sag and wobble, resulting in a poor user experience, please refer to [link to relevant documentation]. Figure 10-12In this embodiment, at least one receiving groove 24 is provided on the connecting shaft 19, and a first elastic member 25 is provided in the receiving groove 24. The two sides of the first elastic member 25 abut against the rotating wheel portion 21 and the connecting shaft 19, respectively. The design of the receiving groove 24 is such that when the connecting shaft 19 rotates, the wall of the receiving groove 24 can generate a rotational force on the first elastic member 25, thereby enabling the first elastic member 25 to rotate with the rotation of the connecting shaft 19. The structural design that allows the first elastic member 25 to rotate with the rotation of the connecting shaft 19 can solve the problem of the first elastic member rotating while the connecting shaft 19 rotates. When 25 remains stationary, the rotation of the connecting shaft 19 applies an additional torque to the first elastic element 25, which could damage the first elastic element 25. At the same time, this additional torque can prevent the first elastic element 25 from rotating 90°, thus preventing the first elastic element 25 from providing elastic force for the tight contact between the connecting shaft 19 and the rotating wheel 21, which would lead to the handle 18 sagging and wobbling. In addition, the depth of the receiving groove 24 allows the first elastic element 25 to have more room for deformation, thereby obtaining greater elasticity and further improving the anti-wobbling effect.

[0063] In this embodiment, the first elastic element 25 is arc-shaped, with its two ends abutting against the two ends of the connecting shaft 19, and its middle section abutting against the rotating wheel portion 21. In this embodiment, during the installation of the first elastic element 25 into the rotating wheel portion 21, the first elastic element 25 is gradually compressed, the distance between its two ends gradually increases, and the distance between the straight line connecting its two ends and the middle section of the first elastic element 25 gradually decreases. When the first elastic element 25 is installed into the rotating wheel portion 21, it always provides an elastic force to ensure a tight abutment between the connecting shaft 19 and the rotating wheel portion 21. Even during the rotation of the connecting shaft 19, the first elastic element 25 remains compressed, thus providing an elastic force to the connecting shaft 19 and ensuring a tight abutment between it and the rotating wheel portion 21.

[0064] In this embodiment, to enhance the elastic force provided for the tight contact between the connecting shaft 19 and the rotating wheel 21, multiple first elastic elements 25 are provided. These multiple first elastic elements 25 are respectively provided on each side of the connecting shaft 19. The multiple first elastic elements 25 further enhance the elastic force provided for the tight contact between the connecting shaft 19 and the rotating wheel 21, improving the stability of the handle 18 to prevent sagging and wobbling. At the same time, the provision of multiple first elastic elements can reduce the wear and fatigue of individual components and improve the service life of the transmission housing. Furthermore, when one of the first elastic elements cannot provide elastic force to the connecting shaft 19, the other first elastic elements can still provide elastic force to the connecting shaft 19, thereby ensuring that the handle 18 does not sagging or wobbling, further improving the service life of the entire door and window handle structure.

[0065] More specifically, taking the square connecting shaft 19 as an example, one first elastic element 25 is provided, located on one side of the connecting shaft 19. The design of a single first elastic element 25 is simple and has low manufacturing cost, but its stability is relatively poor. Alternatively, two first elastic elements 25 can be provided, located on adjacent sides of the connecting shaft 19, or on opposite sides of the connecting shaft 19. The design of two first elastic elements 25 is more complex in structure and manufacturing cost than the design of a single first elastic element 25. The cost is high, but its stability is relatively good; there are 3 first elastic elements 25, which are respectively set on the three sides of the connecting shaft 19. The structure of the 3 first elastic elements 25 is more complex and the manufacturing cost is higher than that of the 2 first elastic elements 25, but its stability is relatively good; there are 4 first elastic elements 25, which are respectively set on the four sides of the connecting shaft 19. The structure of the 4 first elastic elements 25 is more complex and the manufacturing cost is higher than that of the 3 first elastic elements 25, but its stability is relatively good.

[0066] Please see Figure 13-15 In this embodiment, a second elastic element 26 is further included. A first receiving portion 27 is provided on the connecting shaft 19 at a position corresponding to the middle section of the first elastic element 25. The second elastic element 26 is installed in the first receiving portion 27. One end of the second elastic element 26 abuts against the connecting shaft 19, and the other end of the second elastic element 26 abuts against the middle section of the first elastic element 25. By additionally providing the second elastic element 26 and positioning it corresponding to the middle section of the first elastic element 25, this embodiment further enhances the elastic force on the connecting shaft 19 and the rotating wheel portion 21, and improves the stability of the connection between the connecting shaft 19 and the rotating wheel portion 21. At the same time, the design of the second elastic element 26 can reduce the damage to the first elastic element 25 caused by elastic deformation, thereby extending the service life of the first elastic element 25 and thus improving the service life of the entire door and window handle structure.

[0067] The second elastic element 26 can be a spring. Using a spring for the second elastic element 26 eliminates the need for additional specific production and manufacturing of the second elastic element 26, thereby reducing the manufacturing cost of the entire device, shortening the manufacturing cycle of the entire device, and improving the production efficiency of the product.

[0068] Please see Figure 16 and Figure 17In this embodiment, two fixing members 28 are also included. The two ends of the first elastic member 25 are respectively connected to the two ends of the connecting shaft 19 via the fixing members 28. At least one end of the first elastic member 25 is provided with an elongated hole (not shown in the figure), and the fixing member 28 is disposed within the elongated hole to accommodate the displacement caused by the deformation of the first elastic member 25. This embodiment achieves the fixation of the first elastic member 25 to the connecting shaft 19 through the two fixing members 28, solving the problem that when the connecting shaft 19 rotates while the first elastic member 25 remains stationary, the rotation of the connecting shaft 19 applies an additional torque to the first elastic member 25, thereby damaging the first elastic member 25. Simultaneously, it solves the problem that this additional torque would cause the first elastic member 25 to rotate 90°, resulting in the first elastic member 25 being unable to provide the elastic force for the tight contact between the connecting shaft 19 and the rotating wheel 21, thus causing the handle 18 to droop and wobble. Furthermore, the fixing method of this embodiment using two fixing members 28 is superior to the fixing method using the receiving groove 24. The method is more reliable. In this embodiment, the first elastic element 25 is fixed to the connecting shaft 19 by two fixing members 28. When the first elastic element 25 is compressed, the distance between its two ends does not change. Instead, it bears the force through overall deformation. Since the distance between the two ends of the first elastic element 25 does not change, there is no friction between it and the connecting shaft 19, so as not to damage the first elastic element 25 and the connecting shaft 19. At the same time, the fixing members 28 prevent the first elastic element 25 from sliding along the length direction of the connecting shaft 19, so that the connecting shaft 19 cannot be tightly abutted against the rotating wheel part 21, which would cause the handle to shake and droop.

[0069] It should be noted that the different structural designs in the above embodiments can be combined according to the actual use scenario, thereby improving the installation convenience of the entire door and window handle installation structure and optimizing the user experience. As for other combined structural designs, this application will not elaborate on them one by one.

[0070] This invention discloses a lock cylinder cover 4 mounting structure, comprising: a lock body 1 and a lock cylinder cover 4. The lock body 1 is mounted on a door leaf 5. A lock cylinder 2 is detachably mounted on the lock body 1 via a connector 3. The lock cylinder cover 4 is inserted into the end position of the lock cylinder 2 and installed in the mounting hole of the door leaf 5. When the connector 3 is tightened to secure the lock cylinder 2, the lock cylinder 2 pulls the lock cylinder cover 4 along the tension direction of the connector 3 to press against the mounting hole of the door leaf 5. This invention achieves installation by using the connection between the lock cylinder 2 and the lock cylinder cover 4 when the lock cylinder 2 is tightened to the lock body 1 via the connector 3, thereby pulling the lock cylinder cover 4 against the mounting hole of the door leaf 5, eliminating the need for other connecting parts and greatly improving installation efficiency. In addition, by adjusting the position of the connecting shaft 19 and the handle 18 through the fastener 22, the handle can press against the handle cover 20 to be installed on the door leaf 5, making the overall structure more compact, optimizing the user experience and simplifying the installation process.

[0071] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably.
