Description

Technical Field

[0001] This utility model relates to the field of door lock technology, and in particular to a door lock that can hide the connecting parts of the front and rear locks while intuitively indicating the deadbolt status of the door lock. Background Technology

[0002] The deadbolt function is an important security feature of door locks. It allows users to enter a higher level of locking from the inside of the door through specific operations, thereby effectively preventing the door from being opened from the outside using conventional keys or technical means, and improving the level of security.

[0003] In existing technology, door locks with deadbolt function typically include an operable deadbolt component. Users operate the deadbolt component to switch between the deadbolt and unlocked positions to achieve or disengage the deadbolt state.

[0004] However, these types of locks have a common problem: users often find it difficult to quickly and intuitively determine whether the lock is deadbolted visually. For example, because the locks lack obvious indicators, users need to try turning the knob or pulling the handle to confirm whether the lock is deadbolted.

[0005] Furthermore, door locks generally consist of a front lock located on the outside of the door and a rear lock located on the inside of the door. The two are usually mechanically connected by connectors such as studs. Fasteners such as screws can be passed through the through holes on the rear lock and screwed into the studs connected to the front lock to fix the front and rear locks to the door panel.

[0006] The exposed screw holes for fasteners are aesthetically unappealing. Existing technology typically uses plugs of a similar color to the back lock housing to cover them; however, since these plugs are always visible, and their color and texture rarely match the housing, and there are gaps or discontinuities, they still look unsightly.

[0007] Other solutions exist, such as adding an additional removable cover to the rear lock to conceal the screw holes. However, this cover requires space for the deadbolt knob to rotate, necessitating a large circular hole, thus compromising the lock's aesthetics. Furthermore, the removable cover requires a detachable latching mechanism, increasing manufacturing costs and adding to assembly complexity. Utility Model Content

[0008] The purpose of this utility model is to solve at least one of the above-mentioned problems and / or other problems existing in the prior art.

[0009] To achieve the above objectives, according to one aspect of the present invention, a door lock is provided, comprising a front lock and a rear lock. The rear lock includes a housing and a deadbolt member, the housing being fixed to the front lock by fasteners; the deadbolt member is disposed on the side of the housing away from the front lock, the deadbolt member being operable to switch between a deadbolt position and an unlocked position; wherein the housing has a position indicator on the side away from the front lock, wherein the deadbolt member can obscure the position indicator when in one of the deadbolt and unlocked positions, and expose the position indicator when in the other of the deadbolt and unlocked positions.

[0010] According to one embodiment of the present invention, the locking member includes a pivot portion inserted into the housing and a handle portion connected to the pivot portion. The handle portion protrudes into at least one side in a long strip shape along the diameter direction of the pivot portion, so as to cover or expose the position indicator via the handle portion when the locking member rotates around the pivot portion.

[0011] According to one embodiment of the present invention, the rear lock further includes a handle extending into the housing, wherein the central axis of the handle's pivot and the central axis of the pivot of the anti-locking member extend parallel to each other in the same plane.

[0013] According to one embodiment of the present invention, the central axis of the first through hole is located in the plane, and the first through hole is disposed on the side of the rotating shaft opposite to the handle.

[0014] According to one embodiment of the present invention, the central axis of the first through hole is located on one side of the plane and is parallel to the plane.

[0015] According to one embodiment of the present invention, the housing is provided with two first through holes, which are respectively provided on both sides of the plane. The two position indicators are respectively provided at the corresponding first through holes. When the anti-locking member is in the anti-locking position or the locked position, the handle part covers the two position indicators.

[0016] According to one embodiment of the present invention, the housing includes a cover disposed on the side away from the front lock, and a second through hole on the cover communicates with the first through hole.

[0017] According to one embodiment of the present invention, the position indicator is disposed on the surface of the first through hole or the second through hole and covers the fastener.

[0018] According to one embodiment of the present invention, the position indicator indicates the locked or unlocked position by means of an indicative shape or indicative color.

[0019] According to one embodiment of the present invention, the position indicator is green and is exposed when the deadbolt is in the deadbolt position; or, the position indicator is red and is exposed when the deadbolt is in the unlocked position; or, the position indicator is provided with an unlock icon or a deadbolt icon.

[0020] According to one embodiment of the present invention, the anti-locking member rotates 90 degrees between the unlocked position and the anti-locked position.

[0021] This utility model of a door lock, through the cooperation of a deadbolt component and a position indicator, clearly displays the lock's deadbolt and unlock states, improving user convenience and identification efficiency.

[0028] Embodiments of the present invention are described below with reference to the accompanying drawings. In the following description, numerous specific details are set forth to enable those skilled in the art to more fully understand and implement the present invention. However, it will be apparent to those skilled in the art that implementations of the present invention may not include some of these specific details. Furthermore, it should be understood that the present invention is not limited to the specific embodiments described. Rather, the present invention can be conceived to be implemented with any combination of the features and elements described below, regardless of whether they relate to different embodiments. Therefore, the features, embodiments, and advantages described below are for illustrative purposes only and should not be construed as elements or limitations of the claims unless expressly set forth in the claims.

[0029] The terms "first" and "second" are used below to describe the elements of this application. These terms are used only to distinguish the individual elements and not to limit the nature, order, or number of these elements. The terms "comprising" and "having" are used to indicate an open-ended inclusion and mean that there may be additional elements / components besides those listed.

[0030] Figures 1 to 3 A door lock according to one embodiment of the present invention is shown. For example... Figures 1 to 3 As shown, the door lock according to this embodiment may include a front lock (not shown), a lock body 1, and a rear lock 2. The front lock is located on the outside of the door (i.e., the side of the door facing outwards), and the rear lock 2 is located on the inside of the door (i.e., the side of the door facing inwards). The rear lock 2 may include a housing 21 and a deadbolt member 22. A connector 3 is connected to the front lock, which may be, for example, a stud with internal threads at one end. Fasteners (not shown, such as screws) pass through a first through hole 23 on the housing 21 and are screwed into the internal threads of the connector 3, thereby fixing the front lock and the rear lock 2 together and fixing the front lock and the rear lock 2 together to the door.

[0031] The deadbolt member 22 is located on the side of the housing 21 away from the front lock and can be operated to switch between the deadbolt position and the unlock position by moving or rotating. Thus, when the deadbolt member 22 is in the deadbolt position, the door lock can only be opened from the inside, and when the deadbolt member 22 is in the unlock position, the door lock can be opened from either the inside or the outside.

[0032] In this embodiment, the door lock according to this embodiment may further include a position indicator 4. The deadbolt member 22 can obscure the position indicator 4 when it is in either the deadbolt or unlocked position, and can expose the position indicator 4 when it is in the other of the deadbolt and unlocked positions. Those skilled in the art will understand that the position indicator 4 can be configured in various ways. In this embodiment, the rear lock 2 may further include a cover 5 disposed on the side of the housing 21 opposite to the front lock, such as... Figures 1 to 3As shown. The cover 5 covers the lower half of the housing 21. The position indicator 4 can be disposed in the second through hole 51 on the cover 5 (i.e., Figure 2 The position indicator 4 (which can be in the form of a plug) is assembled with the cover 5 inside the second through hole 51. The first through hole 23 on the housing 21 corresponds to the second through hole 51. Therefore, the position indicator 4 not only indicates the deadbolt position but also conceals fasteners such as screws that pass through the first through hole 23, making the door lock more aesthetically pleasing.

[0033] Those skilled in the art will understand that although a separate cover 5 is provided in this example, the cover can be integrated with the housing and become part of the housing. In other words, the cover can also be omitted. It should be noted that although the position indicator 4 is provided in the second through hole 51 in the cover 5 in this specific embodiment, the way the position indicator 4 is provided is not limited to this. For example, when a cover 5 is provided, the second through hole 51 may not be provided in the cover 5, and it may be directly attached (e.g., pasted) to the appropriate position of the cover 5 to serve as an indicator; when a cover 5 is not provided, the position indicator 4 may be directly provided in the first through hole 23 of the housing 21 or on the surface of the first through hole 23, which can also cover the fastener to serve as a shield and hide it.

[0034] As an example, the position indicator 4 can serve as a schematic representation of the locked state. In this case, the position indicator 4 can be exposed when the locking member 22 is in the locked position or obscured when it is in the unlocked position, indicating whether the door lock is locked or unlocked. The position indicator 4 can also serve as a schematic representation of the unlocked state. In this case, the position indicator 4 can be exposed when the locking member 22 is in the unlocked position or obscured when it is in the locked position, indicating whether the door lock is unlocked or locked.

[0035] Compared to existing technologies, the door lock according to this embodiment, through the cooperation of the deadbolt component 22 and the position indicator 4, can clearly display the switch between the deadbolt and unlocked states of the door lock via the position indicator 4, improving user convenience and recognition efficiency. Furthermore, the position indicator 4 conceals the fasteners connecting the front and rear locks 2, providing status indication while also improving the door lock's appearance, making the product more appealing to users.

[0036] refer to Figure 2 and Figure 4As shown, the locking member 22 according to this embodiment may include a pivot portion 221 and a handle portion 222. A hole 24 is provided on the housing 21, and correspondingly, a hole 52 is provided on the cover 5. The pivot portion 221 passes through the hole 52 and the hole 24 and is inserted into the housing 21. The handle portion 222 protrudes into at least one side in a strip shape along the diameter direction of the pivot portion 221, allowing the handle portion 222 to rotate around the pivot portion 221 to rotate the locking member 22 between an unlocked position and a locked position. The range of motion of the handle portion 222 can be a fan-shaped area rotating through a certain angle (typically 90°). A position indicator 4 is provided within the extended length range of the handle portion 222 when the locking member 22 is in the locked or unlocked position, so that the position indicator 4 can be obstructed when the locking member 22 rotates around the pivot portion 221 to the unlocked or locked position.

[0037] like Figures 2 to 4 As shown, the rear lock 2 according to this embodiment may further include a handle 6. A first handle hole 25 is provided on the housing 21, and a second handle hole 53 is provided on the cover 5. The pivot 61 of the handle 6 passes through the second handle hole 53 and the first handle hole 25 and extends into the housing 21 to operate the door lock. Preferably, the central axis of the pivot 61 of the handle 6 and the central axis of the pivot portion 221 of the deadbolt member 22 can extend parallel to each other in the same plane α. For example, the central axis of the pivot portion 221 of the deadbolt member 22 is located directly above or directly below the central axis of the pivot 61 of the handle 6. As an example, the extension direction of the handle portion 222 of the deadbolt member 22 can be set to be perpendicular to the plane α when it is in the deadbolt or unlocked position. Alternatively, the extension direction of the deadbolt member 22 can be set to be along the L direction of the plane α when it is in the deadbolt or unlocked position.

[0038] exist Figures 1 to 4 In the illustrated embodiment, the central axis of the first through hole 23 lies within plane α. That is, within plane α, the central axis of the pivot portion 221 of the locking member 22, the central axis of the pivot 61 of the handle 6, and the central axis of the first through hole 23 are parallel to each other. Preferably, the first through hole 23 may be located on the side of the pivot portion 21 opposite to the pivot 61 of the handle 6. Figure 3 (As shown on the lower side). This allows the extending direction of the locking member 22 to be (as shown on the lower side). Figure 3 The vertical direction (in the image) is set so that when it extends along the plane α, it is in the unlocked position. At this time, the position indicator 4 serves as a schematic structure for the locked state, that is, the locking component 22 is rotated to the locked position. Figure 3 When the horizontal position is displayed, the position indicator 4 is exposed (e.g., green to indicate deadbolt or printed with a deadbolt pattern), indicating that the position is in the deadbolt position.

[0039] Figure 5Another embodiment according to the present invention is shown. In this embodiment, the central axis of the first through hole is located on one side of plane α and is parallel to plane α. That is, the first through hole is provided on one side of plane α, and the central axis of the pivot portion 221 of the locking member 22, the central axis of the pivot 61 of the handle 6, and the central axis of the first through hole are parallel to each other. As an example, the extension direction of the locking member 22 can be set such that it is in the locked position when extending in the L direction perpendicular to plane α. At this time, the position indicator 4 can serve as an indication of the unlocked state, i.e., in the... Figure 5 The location shown in the image, with its exposed position indicator, indicates that the device is in an unlocked state.

[0040] Continue to refer to Figure 5 As shown, preferably, the housing 21 according to this embodiment is provided with two first through holes, which are respectively provided on both sides of the plane α, and preferably symmetrically arranged on both sides of the pivot portion 221 of the locking member 22. Correspondingly, two position indicators 4 are provided at the two first through holes one to one. Thus, when the locking member 22 is in the locked position, the handle portion 222 extends from the pivot portion 221 to both sides in the diametrical direction, which can simultaneously block the two position indicators 4.

[0041] Of course, in other embodiments, if the extension direction of the locking member 22 is set to be perpendicular to the plane α in the L direction when it is in the unlocked position, the position indicator 4 can also be used as a schematic structure of the locking state. When the position indicator 4 is exposed, it indicates that it is in the locking state.

[0042] Preferably, in this embodiment, the housing 21 also includes a cover 5. The cover 5 has two second through holes that communicate with the first through hole. As described above, the two position indicators 4 are correspondingly positioned at the two second through holes, covering the surface of the second through holes, thus providing both position indication and coverage of the fasteners in the first through hole.

[0043] In the two embodiments described above, the position indicator 4 may indicate the locked or unlocked position in an indicative shape or indicative color.

[0044] As a specific example, such as Figure 1 As shown, the handle portion 221 of the deadbolt member 22 is set to the unlocked position when extending along plane α, and to the deadbolt position when extending perpendicular to plane α. When the position indicator 4 is green and located on the side of the pivot 61 of the pivot portion 221 away from the handle, the position indicator 4 is visible when the deadbolt member 22 is in the deadbolt position, indicating that the door lock is in a deadbolt state and is secure. Optionally, a deadbolt icon can also be provided on the position indicator 4.

[0045] As another specific example, such as Figure 5 As shown, the handle portion 221 of the deadbolt member 22 is set to the unlocked position when extending along plane α, and to the deadbolt position when extending perpendicular to plane α. When the two position indicators 4 are red and located on opposite sides of plane α, the two position indicators are visible when the deadbolt member 22 is in the unlocked position, indicating that the door lock is unlocked and therefore unsafe. Optionally, the position indicators 4 can also be equipped with an unlock icon.

[0046] The locking member 22 rotates 90° between the unlocked and locked positions, meaning that the longitudinal extension direction of the handle portion 222 is not limited to the unlocked / locked positions. Figure 1-5 The horizontal or vertical position shown is not explicitly stated. Conversely, as another example, the locked position can also be located at a 45-degree angle relative to the horizontal plane in the longitudinal extension direction of the handle portion 222, and the unlocked position is correspondingly located perpendicular to that position, and vice versa. Furthermore, exemplarily, such as... Figure 1-5 As shown, the handle 6, the deadbolt 22, and the position indicator 4 can be located in the lower part of the rear lock.

[0047] Various modifications and variations can be made to the embodiments disclosed above without departing from the scope or spirit of this invention. Other embodiments of this invention will be apparent to those skilled in the art based on the practice of this invention disclosed in this specification.
