Description

Technical Field

[0001] This utility model relates to the field of lock technology, and in particular to a lock for bathroom use. Background Technology

[0002] Locks are widely used in various fields as door and window sealing devices. With the development of the times, locks now play not only a protective role, but also an indispensable role in management and decoration, especially the lever locks installed on most doors today.

[0003] Existing locks have T-shaped blocks and T-shaped slots on the panel. The T-shaped blocks are difficult to demold during production due to their shape, resulting in a high defect rate and high cost. Utility Model Content

[0004] Therefore, there is a need to provide a bathroom lock that solves the technical problem of existing locks having T-shaped blocks and T-slots on the panel, where the T-shaped blocks are difficult to demold during production due to their shape, resulting in a high defect rate and high cost.

[0005] To achieve the above objectives, this utility model provides a bathroom lock, comprising:

[0006] Lock cylinder assembly;

[0007] Two sets of handle assemblies are provided. The inner handle assembly passes through the lock cylinder assembly and connects to the outer handle assembly. The two sets of handle assemblies are located on both sides of the bathroom panel. The handle assembly includes a handle, a panel, a positioning post, a cover, and a positioning sleeve. The handle is installed on the outer side of the panel. The inner side of the panel is provided with three or more positioning posts. The cover is equipped with positioning sleeves at the corresponding positions of the three or more positioning posts. The positioning sleeves are positioned and connected to the positioning posts. The cover is used to contact the bathroom panel.

[0008] Unlike existing technologies, the technical solution of this application has three or more positioning posts on the inner side of the panel, which are positioned and connected to positioning sleeves installed on the cover. The shape of the positioning posts, compared to T-shaped blocks, makes demolding easier during production, reducing the defect rate and thus lowering costs. Furthermore, the cover, designed for contact with the bathroom panel material, can replace the original adhesive strip, providing both anti-slip properties and a more aesthetically pleasing appearance.

[0009] In one embodiment of this utility model, the cover is fitted to the panel, and the outer edge of the cover is smaller than the outer edge of the panel.

[0010] In this way, the cover fits snugly against the inner side of the panel, and the two are connected by a positioning sleeve and a positioning post. In addition, by making the outer edge of the cover smaller than the outer edge of the panel, the cost of the cover is reduced, and the cover is more aesthetically pleasing when hidden by the panel.

[0011] As one embodiment of this utility model, a positioning post is provided at each of the four corners of the inner side of the panel.

[0012] Thus, by setting four positioning posts and four positioning sleeves to cooperate, the positioning connection between the cover and the panel is more stable.

[0013] In one embodiment of this utility model, the positioning post is a cylinder or a frustum.

[0014] Therefore, by setting the positioning pin as a cylinder or frustum, it is easier to demold and easier to cooperate with the positioning sleeve to strengthen the connection.

[0015] As one embodiment of this utility model, the bathroom lock also includes a safety component, which is installed inside the inner handle and controls the locking or unlocking of the lock cylinder component.

[0016] In this way, a locking cylinder assembly can be installed on the inside of the safety component to lock the bathroom panel and prevent unauthorized entry.

[0017] In one embodiment of this utility model, the safety assembly includes two locking members, a pushing member, and a pushing slider. Two locking holes are provided on the handle. The two locking members are parallel to a first direction and are correspondingly installed in the locking holes. One end of each locking member faces the pushing member. The pushing member is installed inside the handle and has a pushing slider mounted on it. A sliding groove is provided on the inner side of the handle, allowing the pushing slider to slide within the sliding groove along a second direction. Two spaced-apart unlocking grooves and a locking groove are provided on the pushing member. The unlocking grooves accommodate the locking members, causing them to retract along the first direction to unlock the lock cylinder assembly. The locking grooves allow the locking members to extend along the first direction to lock the lock cylinder assembly. The first direction is perpendicular to the second direction.

[0018] Thus, a pusher and two locking elements are provided, so that the two locking elements work together to lock the lock cylinder assembly, thereby preventing the safety mechanism from failing.

[0019] In one embodiment of this utility model, one end of the two locking members is hemispherical, and the locking groove is an arc-shaped groove.

[0020] Thus, the two locking components are designed with a hemispherical shape at one end that mates with the pushing component, facilitating the engagement between the pushing and locking components. Furthermore, the locking groove is an arc-shaped groove that fits snugly against the hemispherical shape, making it easy to accommodate the locking component.

[0021] As one embodiment of this utility model, the bathroom lock also includes a frame, on which a clamping groove is provided extending in a third direction. The clamping groove is used to install on the bathroom panel, and the frame has a latch hole in the clamping groove that cooperates with the lock cylinder assembly.

[0022] Thus, by setting the clamping groove, it is easy to clamp the frame onto the bathroom panel.

[0023] As one embodiment of this utility model, the lock cylinder assembly includes a lock cylinder shell and a lock tongue. The lock cylinder shell passes through the clamping groove, and the lock tongue is movably installed inside the lock cylinder shell. The position of the lock tongue is aligned with the lock tongue hole, and the lock tongue hole accommodates the lock tongue.

[0024] Thus, the bathroom panel can be opened or closed by the cooperation of the latch hole and the latch.

[0025] In one embodiment of this utility model, the cover and the positioning sleeve are integrally formed.

[0026] Therefore, by making the cover and positioning sleeve integrally molded, it is easier to demold during production, and the integral molding structure is more stable.

[0027] The above description of the utility model is merely an overview of the technical solution of this application.

[0051] Existing locks have T-shaped blocks and T-shaped slots on the panel. The T-shaped blocks are difficult to demold during production due to their shape, resulting in a high defect rate and high cost.

[0052] In view of this, this application provides a bathroom lock, including a lock cylinder assembly and two sets of handle assemblies 1; the inner handle assembly 1 passes through the lock cylinder assembly and is connected to the outer handle assembly 1. The two sets of handle assemblies 1 are located on both sides of the bathroom panel 100. The handle assembly 1 includes a handle 11, a panel 12, a positioning post 13, a cover 14 and a positioning sleeve 15. The handle 11 is installed on the outer side of the panel 12. The inner side of the panel 12 is provided with three or more positioning posts 13. The cover 14 is equipped with positioning sleeves 15 at the corresponding positions of the three or more positioning posts 13. The positioning sleeves 15 are positioned and connected to the positioning posts 13. The cover 14 is used to contact the bathroom panel 100.

[0053] According to some embodiments of this application, please refer to Figures 1 to 9 This embodiment relates to a bathroom lock, including a lock cylinder assembly and two sets of handle assemblies 1; the inner handle assembly 1 passes through the lock cylinder assembly and is connected to the outer handle assembly 1. The two sets of handle assemblies 1 are located on both sides of the bathroom panel 100. The handle assembly 1 includes a handle 11, a panel 12, a positioning post 13, a cover 14, and a positioning sleeve 15. The handle 11 is installed on the outer side of the panel 12. The inner side of the panel 12 is provided with three or more positioning posts 13. The cover 14 is equipped with positioning sleeves 15 at the corresponding positions of the three or more positioning posts 13. The positioning sleeves 15 are positioned and connected to the positioning posts 13. The cover 14 is used to contact the bathroom panel 100.

[0054] The lock cylinder assembly can be located on one side of the bathroom panel 100 or at one end of the bathroom panel 100. The lock cylinder assembly is an existing lock cylinder structure, so it will not be described in detail.

[0055] The inner handle assembly 1 is the handle assembly 1 inside the bathroom panel 100, and the corresponding outer handle assembly 1 is the handle assembly 1 outside the bathroom panel 100. The bathroom panel 100 can be a door or window panel, or any other panel that can be fitted with locks.

[0056] The inner side of panel 12 is provided with three or more positioning posts 13. For example, the inner side of panel 12 is provided with three positioning posts 13, which are arranged in a triangle, and the triangular structure is more stable.

[0057] The technical solution of this application provides three or more positioning posts 13 on the inner side of the panel 12, and the positioning posts 13 are positioned and connected to the positioning sleeves 15 installed on the cover 14. The shape of the positioning posts 13, compared to T-shaped blocks, makes demolding easier during production, reducing the defect rate and thus lowering costs. Furthermore, the cover 14 is provided for contact with the bathroom panel 100, replacing the original adhesive strip, providing both anti-slip properties and a more aesthetically pleasing appearance.

[0058] like Figure 3 As shown, the cover 14 fits into the panel 12, and the outer edge of the cover 14 is smaller than the outer edge of the panel 12.

[0059] Thus, the cover 14 fits snugly against the inner side of the panel 12, and the two are positioned and connected by the positioning sleeve 15 and the positioning post 13. In addition, by setting the outer edge of the cover 14 to be smaller than the outer edge of the panel 12, the cost of the cover 14 is reduced, and the cover 14 is more aesthetically pleasing when hidden by the panel 12.

[0060] like Figure 4 and Figure 5 As shown, a positioning post 13 is provided at each of the four corners of the inner side of the panel 12.

[0061] The cover 14 is also provided with four positioning sleeves 15 corresponding to the four positioning posts 13. In this way, the four positioning posts 13 and the four positioning sleeves 15 cooperate to make the positioning connection between the cover 14 and the panel 12 more stable.

[0062] like Figure 4 and Figure 5 As shown, the positioning post 13 is a cylinder or a frustum.

[0063] Thus, by setting the positioning post 13 as a cylinder or frustum, it is more conducive to demolding and easier to cooperate with the positioning sleeve 15 to strengthen the connection.

[0064] like Figure 6 As shown, the bathroom lock also includes a safety component 2. The safety component 2 is installed inside the inner handle 11 and controls the locking or unlocking of the lock cylinder component.

[0065] The safety component 2 can be an existing safety component 2, used to lock the bathroom panel 100. Thus, a locking cylinder assembly can be installed on the inside of the safety component 2 to lock the bathroom panel 100 and prevent unauthorized entry.

[0066] like Figure 7 and Figure 8 As shown, the safety assembly 2 includes two locking members 21, a pushing member 22, and a pushing slider 23. The handle 11 has two locking holes 112. The two locking members 21 are parallel to the first direction X and are correspondingly installed in the locking holes 112. One end of each locking member 21 faces the pushing member 22. The pushing member 22 is installed inside the handle 11, and a pushing slider 23 is mounted on it. A sliding groove 113 is provided on the inner side of the handle 11. The pushing slider 23 slides along the second direction Y within the sliding groove 113. The pushing member 22 has two spaced-apart unlocking grooves 221 and locking grooves 222. The unlocking grooves 221 accommodate the locking members 21, causing them to retract along the first direction X to unlock the lock cylinder assembly. The locking grooves 222 allow the locking members 21 to extend along the first direction X to lock the lock cylinder assembly. The first direction X is perpendicular to the second direction Y.

[0067] The handle 11 has a mounting hole 111, and the handle 11 has a locking hole 112 extending along the first direction X at each end of the mounting hole 111.

[0068] The push slider 23 is fixedly connected to the push member 22. The push slider 23 slides in the sliding groove 113 along the second direction Y, thereby driving the push member 22 connected to it to slide in the handle 11 along the second direction Y. This causes the unlocking groove 221 or locking groove 222 to engage with one end of the two locking members 21 to unlock or lock the lock cylinder assembly. One end of the two locking members 21 is closer to the push member 22, while the other end, farther from the push member 22, extends out to lock the lock cylinder assembly.

[0069] Thus, the pusher 22 and two locking members 21 are provided, so that the two locking members 21 work together to lock the lock cylinder assembly, thereby preventing the safety from failing.

[0070] like Figure 8 As shown, one end of the two locking elements 21 is hemispherical, and the locking groove 222 is an arc-shaped groove.

[0071] Thus, the two locking members 21 are designed with a hemispherical shape at one end that mates with the pushing member 22, facilitating the engagement of the pushing member 22 with the locking member 21. In addition, the locking groove 222 is an arc-shaped groove that fits into the hemispherical shape, making it easy to accommodate the locking member 21.

[0072] like Figure 9As shown, the bathroom lock also includes a frame 3, on which a groove 31 extending in the third direction Z is provided. The groove 31 is used to install on the bathroom panel 100. The frame 3 has a latch hole 32 in the groove 31 that cooperates with the lock cylinder assembly.

[0073] Thus, by setting the clamping groove 31, it is easy to clamp the frame 3 onto the bathroom panel 100.

[0074] According to some embodiments of this application, optionally, the lock cylinder assembly includes a lock cylinder shell and a bolt. The lock cylinder shell passes through the clamping groove 31, and the bolt is movably installed inside the lock cylinder shell. The position of the bolt is aligned with the bolt hole 32, and the bolt hole 32 accommodates the bolt.

[0075] Thus, the bathroom panel 100 can be opened or closed by the cooperation of the locking tongue hole 32 and the locking tongue.

[0076] According to some embodiments of this application, optionally, the cover 14 and the positioning sleeve 15 are integrally formed.

[0077] Thus, by integrally molding the cover 14 and the positioning sleeve 15, it is easier to demold during production, and the integral molding structure is more stable. Similarly, the panel 12 and the positioning post 13 can also be integrally molded.

[0078] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of patent protection for this utility model.
