Technical Field
[0001] The utility model relates to the technical field of door locks, and particularly to the structure of a new type of indoor door lock in the technical field of door locks. Background Art
[0002] Indoor door locks include bedroom door locks, balcony door locks, bathroom door locks, etc. The usage scenarios of indoor door locks are indoors. Their anti-theft requirements are not so strict, and their structures are relatively simple, with an anti-lock function. Indoor door locks are basically installed in each room, bedroom, balcony, and bathroom, and their installation quantity is relatively large. There are the following areas that need further improvement in the current indoor door locks on the market:
[0003] 1. Aluminum alloy glass doors are common indoor doors. Most of the indoor door locks used adopt a two-way rotation structure, that is, the door can be opened by rotating the handle upward or downward. Through the cooperation of a two-way return torsion spring and a positioning dial, a reset structure after the handle rotates is formed with the limiting part on the panel. When the handle rotates downward and upward for a long time, the return torsion spring will undergo fatigue deformation. The positioning dial is generally made by stamping iron sheets, while the panel of the door lock is generally processed from aluminum. The material hardness of the positioning dial is higher than that of the handle. The positioning dial collides with the limiting part on the panel for a long time, resulting in a notch on the limiting part of the panel, thus causing a change in the reset angle of the dial. Coupled with the considerable self-weight of the handle, over time, the handle will sag, unable to maintain a horizontal line, affecting the use comfort and aesthetics of the indoor door lock. Seriously, it will also lead to the embarrassing situation that the indoor door lock can be opened by gently touching the handle, reducing the overall service life of the indoor door lock.
[0004] 2. Some high-end indoor doors use wooden doors and are matched with mid-to-high-end indoor door locks. The inner handle and the inner panel, and the outer handle and the outer panel are assembled and fixed during production, and the orientations of the inner handle and the outer handle are also fixed. During the installation process, for different door opening methods, such as different situations of left-inside opening, right-inside opening, left-outside opening, and right-outside opening of the indoor door, the installation position or the handle orientation of the indoor door lock is different. Most mid-to-high-end indoor door locks are single-direction locks (that is, the handle of the indoor door lock can only rotate downward), and the rotation direction of their handles is also different. Therefore, when installers install indoor door locks, it is easy to have the situation that the purchased indoor door lock does not correspond to the installation position or the handle orientation of the indoor door. For the manufacturers of indoor door locks, due to the inability to determine the usage quantities of different installation positions or handle orientations of indoor door locks, they cannot accurately produce and stock up, and the production and operation costs are also relatively increased.
[0005] In view of the above problems, a structure of a new type of indoor door lock is specifically developed. Content of the Utility Model

The paddle is moved toward the lock rod and the lock rod is pressed downward through the lock column until the lock rod is inserted into the anti-lock hole of the panel to form an anti-lock structure. The front end of the lock column can be set at an angle to make it more convenient for the lock column to lock the lock rod. The inner door handle is locked or unlocked by pushing the paddle of the inner handle. The structure of the anti-locking function is realized by the lock rod of the inner handle and the anti-locking hole of the panel. The inner surface of the interior door is identical to the outer panel structure and can be interchanged. When there are various confusing ways to open the interior door, there will be no situation where the wrong interior door lock is purchased. The panel is provided with a rotating hole, the rotating hole is equipped with a lock cylinder, the lock cylinder is connected to a square shaft, one end of the lock cylinder is provided with a lock seat, the other end is provided with a rotating seat, the rotating seat of the lock cylinder passes through the rotating hole of the panel and is equipped with a torsion spring, a one-way clamp ring, and a clamp spring to form a one-way downward rotation of the lock cylinder on the panel. The installation structure, the one-way clamping ring restricts the lock cylinder to only be able to do a one-way downward rotation structure, the inner handle and the outer handle can only be rotated downward, the torsion spring forms a horizontal reset structure for the lock cylinder and the inner handle and the outer handle after they are rotated downward, the torsion spring can also be provided with a surplus reset elastic force, the horizontal reset state of the handle is more stable, effectively preventing the handle of the traditional indoor door lock from sagging or failing to maintain a horizontal state; the lock seat is provided with a mounting hole 1, the inner handle and the outer handle are provided with a mounting hole 2, the mounting hole 2 of the outer handle is the same as the inner handle, and it is not necessary to indicate it in the drawings, the inner handle and the outer handle are respectively connected to the panel through the mounting hole 1 and the mounting hole 2 A detachable installation structure is formed, and the inner handle and panel or the outer handle and panel are all structures that can be detached and assembled separately. During the installation process, since the inner and outer panel structures of the interior door are the same, the panel can be installed first, and then the inner and outer handles can be installed accordingly according to the opening method of the interior door and the direction of the handle. The installation is more convenient. The anti-lock structure of the traditional interior door lock is set on the panel and lock core on the inner surface of the interior door, or the handle and panel are an integrated structure, and the inner panel and the outer panel are not interchangeable. Since there are relatively many interior door locks installed and the door opening methods are different, it is easy to purchase the wrong interior door lock.
[0041] In the utility model, the lock cavity is provided with a rebound hole, the upper part of the rebound hole is provided with a rebound part, the lower part of the rebound hole is provided with a locking part, the diameter of the rebound part is larger than the diameter of the locking part, the lock rod is provided with a bullet head and a rod body, the top of the bullet head is arc-shaped, the diameter of the bullet head is larger than the diameter of the rod body, the rod body is sleeved with a spring inserted into the rebound hole to form a rebound installation structure of the lock rod in the rebound hole, when the paddle is pushed toward the direction of the lock rod and the lock rod is pressed downward through the lock column until the lock rod is inserted into the anti-lock hole of the panel, the indoor door lock forms an anti-lock structure.
[0042] In the utility model, the paddle is provided with a paddle handle, the inner handle is provided with a lock window, the paddle handle is installed on the lock window and a locking and unlocking structure is formed by horizontally paddle-pulling the paddle handle.
[0043] In the present utility model, the rotating seat is provided with a sleeve, and the one-way clamp is provided with a clamping head and a limiting part. After the one-way clamp is inserted into the rotating seat, a linkage structure is formed by the clamping head and the sleeve. The panel is provided with a limiting column, and the one-way clamp cooperates with the limiting column of the panel through the limiting part to form a one-way limited rotation structure for downward rotation. Even in the case of an erroneous operation to turn the handle upward, the one-way clamp and the limiting part force the handle to be unable to rotate upward, thus avoiding the fatigue phenomenon of the traditional two-way torsion spring that is prone to horizontal reset in the upward direction, resulting in the handle being unable to reset to a horizontal state and thus sagging; the torsion spring is provided with an inner end clamping head and an outer end clamping head, the inner end clamping head of the torsion spring is inserted into the sleeve, and the outer end clamping head of the torsion spring conflicts with the limiting column of the panel, thereby forming a composite structure after the lock core is rotated on the panel.
[0044] In the utility model, the paddle is provided with an elastic positioning head, and the lock cavity is provided with a positioning recess. The elastic positioning head and the positioning recess cooperate to form a positioning structure for the paddle after horizontally shifting. When the paddle is shifted toward the lock rod, the elastic positioning head slides to the positioning recess of the lock cavity to form a positioning state of the paddle in the lock cavity, thereby realizing the anti-locking function.
[0045] In the present invention, the pick is fixed in the lock cavity by a cover, and the cover can be fixed to the handle by screws to ensure the smooth sliding of the pick in the lock cavity; the handle is provided with a face cover, and the face cover is provided with a magnetic sheet or a film, and the face cover is arranged on the inner handle and the outer handle by magnetic attraction or by gluing the film. If the face cover is arranged by magnetic attraction, a magnetic block can be installed on the inner handle or the outer handle by screws to form a magnetic attraction structure for the face cover, and the face cover increases the aesthetics of the indoor door lock.
[0046] In this new model, the panel is provided with mounting holes, and the panels are mounted with screws through the mounting holes and the anti-locking holes, and there is a remaining anti-locking space in the anti-locking holes. The anti-locking holes of the panel are simultaneously used for the panel mounting structure on the inner and outer surfaces of the interior door and the anti-locking structure formed by the locking rod of the handle and the panel, so that the inner handle and the outer handle can be interchanged and both can realize the anti-locking function, and the installation method of the interior door lock is realized by first installing the panel and then installing the inner handle and the outer handle. The installation error of the interior door lock will not occur, and the installation is more convenient.
[0047] In the utility model, the square shaft is provided with a top cap through the shaft rod and the spring, the paddle is provided with an inclined portion, and the outside handle is provided with an emergency unlocking hole. When the shaft rod is not subjected to external force, the shaft rod will not generate a pushing force on the top cap, and the top cap will not generate a pushing force on the inclined portion of the paddle. The outside handle is provided with an emergency unlocking hole accordingly. When an emergency situation occurs and the interior door lock needs to be opened from the outside of the interior door, the shaft rod is pressed through the emergency unlocking hole of the outside handle until the top cap presses the inclined portion of the paddle. After the inclined portion of the paddle is pressed, it slides in the opposite direction of the lock rod, thereby forming an unlocked state of the interior door lock, and the interior door can be opened through the outside handle.
[0048] In the present invention, the rotating seat cover is provided with a rubber ring, which is located between the rotating seat and the panel. The rubber ring effectively reduces the friction sound between the rotating seat and the panel, thereby improving the comfort of rotating the handle.
[0049] Working principle: When it is necessary to install the interior door lock of the utility model, first install the two panels on the door body through the installation holes and the anti-lock holes by using screw clamps, and then determine the corresponding installation positions or handle directions of the inner handle and the outer handle according to the door opening method, and install the inner handle and the outer handle through the installation hole 1 of the lock seat and the installation hole 2 of the inner handle and the outer handle respectively, thus realizing the installation of the interior door lock; when it is necessary to anti-lock, the paddle is pushed toward the lock rod through the dial handle, and the lock column of the paddle presses the lock rod downward until the lock rod is inserted into the anti-lock hole of the panel, and the interior door lock forms an anti-lock structure. When it is necessary to unlock, the paddle is pushed in the opposite direction of the lock rod through the dial handle, and the lock column of the paddle cancels the downward force on the lock rod, and the lock rod rebounds and withdraws from the anti-lock hole of the panel, and the interior door lock is in the unlocked state, and the door can be opened by turning the inner handle or the outer handle.
[0050] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
