Description

Technical Field

[0001] This utility model relates to the field of door and window accessories technology, specifically to an extremely narrow door and window lock. Background Technology

[0002] Casement windows refer to windows where the movable sash moves along a horizontal direction, hence the name "casement." Casement windows are widely used due to their advantages such as good ventilation, good sealing, sound insulation, heat preservation, and impermeability. With the development of the casement window industry, ultra-narrow casement window structures are now popular. Referring to an ultra-narrow casement window in publication number CN216008221U, this is achieved by using an ultra-narrow frame structure. The same principle applies to casement doors. At the same time, the casement window handle is one of the essential accessories for casement windows, mainly used to open and close the movable sash. Currently, casement window handles are installed on the front of the movable sash frame. However, traditional handle locks are too large to be used on the currently popular ultra-narrow movable sashes. The movable sash frame needs to have enough width to install the handle and its accessories, which limits the current ultra-narrow casement windows from being extremely narrow due to the limitations of the handle structure. Utility Model Content

[0003] To address the technical deficiencies in the background technology, this utility model proposes an extremely narrow door and window lock, which solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows:

[0004] An extremely narrow door and window lock includes a handle and a base. The base is mounted on the decorative surface of a movable sash. One end of the handle is hinged to the base. A locking point positioning structure is provided between the handle and the base.

[0005] The base is provided with a mounting groove that extends through its thickness direction, the front end of the handle extends into the mounting groove, and a movable shaft passes through the width direction of the mounting groove. The movable shaft passes through the width direction of the handle.

[0006] The locking point positioning structures are arranged in pairs and surround both sides of the movable shaft. Each locking point positioning structure includes an elastic element, a positioning ball, and a positioning groove. Positioning steel plates are provided on the inner walls of both sides of the mounting groove, and the positioning groove is opened on the positioning steel plates. A cavity for accommodating the elastic element and the positioning ball is opened on the side of the handle, and a steel sleeve is provided on the inner wall of the cavity.

[0007] As an improvement to the above solution, the positioning groove includes a starting positioning groove and an ending positioning groove, and the positions of the starting positioning groove and the ending positioning groove are arranged circumferentially around the outer edge of the movable shaft.

[0008] As an improvement to the above solution, the chamber has an opening facing outward, the elastic element is disposed at the bottom of the chamber, the positioning ball is disposed in the chamber near the opening, one end of the elastic element abuts against the bottom of the chamber, and the other end abuts against the positioning ball.

[0009] As an improvement to the above solution, the diameter of the positioning groove is smaller than the diameter of the positioning ball.

[0010] As an improvement to the above solution, the end of the handle is provided with a first extension and a second extension extending toward the mounting groove. The first extension and the second extension are arranged in parallel, and a drive shaft is provided between the first extension and the second extension. A roller is sleeved on the outer surface of the drive shaft.

[0011] As an improvement to the above solution, the front part of the handle is provided with a first baffle aligned with the groove opening of the mounting groove, and the rear part of the handle is provided with a second baffle extending vertically toward the bottom of the mounting groove.

[0013] As an improvement to the above solution, the base has downward-facing screw holes at both ends along its length, and screws are installed in the screw holes to connect with the aluminum material of the doors and windows.

[0014] The beneficial effects of this utility model are as follows: the handle is hinged to the base, and the handle is rotated up and down around the rotation axis, so that the transmission shaft at the front end of the handle moves the lock cylinder transmission plate up and down to lock the door and window. Compared with the traditional lever lock, the width of the base and the handle is narrowed, the transmission structure of the handle is simplified, and its volume is reduced, making it suitable for the currently popular ultra-narrow door and window frames. Furthermore, a pair of locking point positioning structures are added between the handle and the base to enhance the user's tactile feedback when the handle is open and closed. The user can clearly perceive the critical point of the handle rotation, effectively preventing the user from excessively rotating the handle. Attached Figure Description

Detailed Implementation

[0022] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0023] A window lock for an extremely narrow door includes a handle 1 and a base 2. The base 2 is mounted on the decorative surface of a movable sash. One end of the handle 1 is hinged to the base 2. A locking point positioning structure 4 is provided between the handle 1 and the base 2.

[0024] In the structure of the base 2, the base 2 has downward-facing screw holes 32 at both ends along its length. Screws 33 are provided in the screw holes 32. In use, the base 2 is embedded into the decorative surface of the openable fan light frame, and the base 2 is fixed in the light frame by screwing the screws 33 in the screw holes 32.

[0025] Furthermore, the base 2 includes a mounting groove 3 extending through its thickness direction. The mounting groove 3 is directly connected to the position of the lock cylinder transmission plate inside the optical engine. The front end of the handle 1 is extended into the mounting groove 3, and the front end of the handle 1 can be directly connected to the lock cylinder transmission plate.

[0026] Furthermore, a movable shaft 31 is provided along the width direction of the mounting groove 3. The movable shaft 31 is provided along the width direction of the handle 1 and is hinged to the handle 1. When the handle 1 is rotated, the handle 1 rotates around the movable shaft 31 as the axis, thereby opening or closing the door and window lock.

[0027] In the technical solution of the locking point positioning structure 4 of this utility model, the locking point positioning structure 4 is arranged in pairs and surrounds both sides of the movable shaft 31. During the rotation of the handle 1, it plays a dual positioning effect, enhances the mechanical feedback when the locking point reaches the designated position, and allows the user to clearly perceive whether the rotation angle of the handle 1 has reached the opening or closing angle, thereby avoiding the situation of excessive rotation of the handle 1.

[0028] Furthermore, in the above scheme, the locking point positioning structure 4 includes an elastic element 41, a positioning ball 42 and a positioning groove 43. The inner walls on both sides of the mounting groove 3 are provided with positioning steel plates 6, and the positioning groove 43 is opened on the positioning steel plates. The side of the handle 1 is provided with a cavity 5 to accommodate the elastic element 41 and the positioning ball 42, and the inner wall of the cavity 5 is provided with a steel sleeve 51.

[0029] It should be noted that, structurally, the chamber 5 has an opening facing outwards, the elastic element 41 is disposed at the bottom of the chamber 5, and the positioning ball 42 is disposed inside the chamber 5 near the opening. One end of the elastic element 41 abuts against the bottom of the chamber 5, and the other end abuts against the positioning ball 42. Under the elastic force of the elastic element 41, the positioning ball 42 slides toward the opening of the chamber 5, thereby abutting against the positioning groove 43 to achieve a positioning effect.

[0030] Furthermore, when the handle 1 is rotated, the positioning ball 42 is squeezed out of the positioning groove 43 in its initial position. When the handle 1 is rotated to the adjacent positioning groove 43, the positioning ball 42 is ejected again under the elastic force of the elastic member 41 and abuts against the positioning groove 43 to achieve positioning.

[0031] Furthermore, in the above scheme, the positioning groove 43 includes a starting positioning groove 431 and an ending positioning groove 432. The starting positioning groove 431 and the ending positioning groove 432 are arranged circumferentially around the outer edge of the movable shaft 31. When the handle 1 is in the closed state, the positioning ball 42 abuts against the starting positioning groove 43 under the action of the elastic element. When the handle 1 is rotated, the positioning ball 42 moves in a circular motion around the movable shaft 31 as the handle 1 rotates, moving from the starting positioning groove 431 to the ending positioning groove 432.

[0032] Furthermore, in the above scheme, the diameter of the positioning groove 43 is smaller than the diameter of the positioning ball 42.

[0033] Furthermore, in the above solution, the end of the handle 1 is provided with a first extension 11 and a second extension 12 extending toward the mounting groove 3. The first extension 11 and the second extension 12 are arranged in parallel. A transmission shaft 13 is provided between the first extension 11 and the second extension 12. A roller 131 is sleeved on the outer surface of the transmission shaft 13. By rotating the other end of the handle 1, the transmission shaft 13 at the front end of the handle 1 drives the roller 131 to move the lock cylinder transmission plate to realize the opening and closing of the door and window lock.

[0034] Furthermore, in the above solution, the front part of the handle 1 is provided with a first baffle 14 aligned with the groove opening of the mounting groove 3, and the rear part of the handle 1 is provided with a second baffle 15 extending vertically toward the bottom of the mounting groove 3. When the handle 1 is in the closed state, the first baffle 14 covers the gap between the upper part of the handle 1 and the base 2. When the handle 1 is in the open state, the second baffle 15 covers the gap between the lower part of the handle 1 and the base 2, effectively preventing the phone from being squeezed in the user's hand due to improper use.

[0035] Furthermore, in the above scheme, a first positioning steel plate 7 is provided between the side of the handle 1 with the cavity 5 and the inner wall of the mounting groove 3, and a second positioning steel plate 8 is provided between the other side of the handle 1 and the inner wall of the mounting groove 3. The first positioning steel plate 7 is provided with a positioning groove 43 corresponding to the position of the positioning ball 42.

[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
