Description

Technical Field

[0001] This utility model relates to the field of hardware lock technology, specifically a push-pull type lever locking mechanism and a door lock. Background Technology

[0002] Push-pull handles are mechanisms that open and close doors by pushing or pulling the handle to control the extension and retraction of the latch. Currently, most existing push-pull handle mechanisms are configured with a single-latch lock body, and most of these single-latch lock bodies lack a locking function. Some push-pull handle mechanisms are configured with a double-latch lock body, where the normal opening and closing of the door is achieved by controlling the movement of the bevel latch, and the locking is achieved by controlling the movement of the square latch. However, double-latch lock bodies usually have complex structures. For example, invention patent CN109629911A discloses a push-pull door lock structure including a bevel latch and a square latch, which has a complex cooperation and transmission system to achieve both opening / closing and locking. How to simplify the existing push-pull handle locking structure and incorporate a locking function into a single-latch lock body is an urgent problem to be solved. Utility Model Content

[0003] The purpose of this utility model is to provide a locking mechanism and door lock for a push-pull handle, aiming to provide a locking solution suitable for a single-tongue lock body with a push-pull handle.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] The first aspect of this utility model provides a push-pull type handle locking mechanism, including a vertically arranged handle body and a mounting base. The lower end of the handle body is connected to the mounting base via a rotating component, and the rotating component is connected to a transmission component for controlling the movement of the latch bolt. The mechanism also includes a drive component connected to the mounting base. The drive component is operably disposed within the mounting base and is configured to abut against the rotating component and restrict the rotation of the rotating component when operated.

[0006] In a preferred embodiment, the mounting base includes a mounting top and a mounting base, which cooperate to form an installation space. The rotating component includes a connecting end and a rotating end. The connecting end is connected to the handle body, and the rotating end extends into the installation space and is rotatably connected to the transmission component installed in the installation space.

[0007] In a preferred embodiment, the transmission assembly includes a rotating shaft that rotatably engages with the rotating end and a paddle, the paddle extending into the rotating end and rotatably connected to the rotating shaft.

[0008] In a preferred embodiment, the drive assembly includes a rotating paddle and a follower block, both of which are movably connected to the mounting base. The position of the follower block corresponds to the rotating end of the rotating component. The rotating paddle is configured to interact with the user and to drive the follower block against the rotating end when operated by the user.

[0009] In a preferred embodiment, the rotating block includes a rotating body and a toggle block fixed to one side thereon. The follower block has a groove at a position corresponding to the rotating block that matches the structure of the toggle block, and the toggle block extends into the groove.

[0010] In a preferred embodiment, the rotating end of the rotating member is provided with at least two rows of vertical grooves distributed in the vertical direction, and the follower block is fixed with locking blocks corresponding to the upper and lower sides of the vertical grooves on the side facing the rotating member.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model 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. Therefore, they should not be construed as limitations on this utility model.

[0027] See Figure 1 This embodiment discloses a push-pull type handle locking mechanism, including a vertically arranged handle body 1 and a mounting base 2. The lower end of the handle body 1 is connected to the mounting base 2 via a rotating member 3, and the rotating member 3 is connected to a transmission component for controlling the movement of the latch bolt. The mounting base 2 is also connected to a drive component for interacting with the outside world. This drive component is operably disposed within the mounting base 2 and is configured to abut against the rotating member 3 when operated by the user, thereby controlling the rotation state of the rotating member 3.

[0028] Understandably, the door lock handle body 1 and the corresponding mounting base 2 and internal components are set into two sets, which are installed on the inner and outer sides of the door respectively. Since the structures on both sides are roughly the same (only the locking knob and lock cylinder structures are different), for the sake of simplicity, this embodiment only introduces the structure on one side.

[0029] Specifically, the handle body 1 has a protrusion fixed at its lower end, and the protrusion has a mounting groove for connecting the rotating component 3. In this embodiment, the rotating component 3 includes a connecting end 31 and a rotating end 32. The connecting end 31 is inserted into the mounting groove and fastened with screws, and the rotating end 32 is installed in the mounting base 2.

[0030] Mounting base 2 includes a mounting housing and a mounting top 21 and a mounting base 22 that are snapped into the mounting housing. The mounting top 21 and the mounting base 22 are connected by screws and cooperate to form a mounting space. The rotating end 32 of the rotating component 3 extends into the mounting space, and the transmission component is disposed in the mounting space.

[0031] The transmission assembly includes a rotating shaft 41 rotatably connected to the rotating end 32 of the rotating member 3, and a lever 42 connected to the rotating end 32. See details... Figure 2 and Figure 3The mounting housing and mounting top 21 are provided with mounting openings that are adapted to the rotating end 32. The rotating end 32 of the rotating component 3 extends into the mounting opening and further into the mounting space. The rotating end 32 is provided with a central through hole that rotatably engages with the rotating shaft 41. The rotating shaft 41 is inserted into the central through hole, thereby causing the rotating component 3 to be rotatably connected to the rotating shaft 41. The mounting top 21 is provided with slots for mounting the rotating shaft 41, and both ends of the rotating shaft 41 are engaged in the corresponding slots. Pushing the handle inward or pulling the handle outward can drive the connecting end 31 of the rotating component 3 to move up and down, thereby enabling the rotating component 3 to rotate slightly up and down synchronously with the rotating shaft 41 as the fulcrum.

[0032] The rotating end 32 has an opening groove 321 on the side facing the mounting base 22 that matches the paddle 42. The paddle 42 extends into the opening groove 321, and one end of it is rotatably connected to the rotating shaft 41. The rotating end 32 can drive the paddle 42 to move synchronously by rotating up and down, thereby achieving the driving cooperation with the tongue.

[0033] The drive assembly is also located within the installation space, and includes a rotating paddle 51 and a follower block 52.

[0034] Combination Figure 4 and Figure 5 The rotating lever 51 is connected to the lower part of the mounting base 22. It includes a rotating body 511 that is generally circular and a lever 512 fixed on one side. Correspondingly, the mounting base 22 and the mounting top 21 are provided with mounting slots that are adapted to the shape of the rotating body 511. The rotating body 511 is embedded in the mounting slot and can rotate relative to the mounting slot.

[0035] The follower block 52 is positioned above the rotating lever 51, corresponding to the position of the rotating member 3. The follower block 52 is embedded in the mounting base 22 and can move horizontally relative to the mounting base 22. The follower block 52 has a groove 521 at the position corresponding to the rotating lever 51, matching the structure of the lever block 512. The lever block 512 extends into the groove 521. Rotating the rotating lever 51 causes the lever block 512 to drive the follower block 52 to move horizontally. Through this horizontal movement, the follower block 52 can act on the rotating member 3 and control its rotation state, achieving a locking or unlocking effect.

[0036] For details, see Figure 6The follower block 52 and the rotating member 3 are positioned correspondingly. The follower block 52 is located near the mounting base 22, and the rotating member 3 is located near the mounting top 21, with the two being staggered. More specifically, the rotating end 32 of the rotating member 3 has at least two rows of vertical grooves 322 distributed in the vertical direction. The follower block 52 facing the rotating member 3 is fixed with locking blocks 522 corresponding to the upper and lower sides of the vertical grooves 322: an upper locking block and a lower locking block. The bottom surface of the upper locking block is on the same horizontal plane as the top surface of the rotating end 32, and the top surface of the lower locking block is on the same horizontal plane as the bottom surface of the rotating end 32. When the upper and lower locking blocks 522 correspond to the positions of the vertical grooves 322 of the rotating member 3, the rotating member 3 can rotate normally, which is the unlocked state. When the follower block 52 moves horizontally, causing the upper and lower locking blocks 522 to move out of the positions of the vertical grooves 322 and abut against the upper and lower surfaces of the rotating end 32, the rotation of the rotating member 3 can be restricted, thereby achieving locking.

[0037] The two sides of the card block 522 are equipped with chamfered guide structures to enable it to move normally and prevent motion interference.

[0038] See Figure 2 and Figure 7 To achieve precise control over the movement distance of the follower block 52, in this embodiment, a positioning post 6 is fixedly provided on the side of the follower block 52 facing the mounting base 22. The positioning post 6 has a spherical protrusion 61 facing the mounting base 22. Correspondingly, the mounting base 22 has a positioning groove 221 matching the spherical protrusion 61 on the side facing the follower block 52. The number of positioning grooves 221 corresponds to twice the number of positioning posts 6, respectively corresponding to the unlocking position and the locking position of the positioning posts 6. By setting the spacing between the two sets of positioning grooves 221, the follower block 52 is guided to achieve precise displacement.

[0039] Furthermore, in this embodiment, the center of the rotating body 511 is provided with a straight-line insertion hole 5111, which is used to cooperate with the lock cylinder and knob of the door lock for user interaction. For example, the outer lock cylinder or the inner knob of the door lock is connected to the same insert plate 7, which is inserted into the insertion hole 5111. Rotating the lock cylinder with the key or rotating the knob can drive the insert plate 7 to rotate, thereby causing the rotating lever 51 to rotate.
