UTILITY MODEL CONTENTS

[0003] The utility model discloses a door lock knob reset mechanism and door lock to solve the above technical problem, set up the installation body and the first magnetic attraction end and the second magnetic attraction end that can be magnetically attracted, so that the knob can rotate on the installation body, and when the first magnetic attraction end rotates close to the second magnetic attraction end, it can be rotated to the target position, which is simple and can effectively align the corresponding unlocking position and locking position.

[0004] Meanwhile, the structure can realize modular assembly, is simple in structure and convenient to assemble, simplifies the assembly process, and has fewer components, so that the machining cost is reduced.

[0005] To achieve the above utility model purposes, the technical scheme adopted by the utility model is as follows:

[0006] A door lock knob reset mechanism comprises a knob, and further comprises a positioning mechanism coaxially arranged with the knob and movably connected with the knob.

[0007] The knob is provided with a first magnetic attraction end, and the positioning mechanism comprises an installation body movably connected with the knob and a second magnetic attraction end arranged on the installation body and magnetically attracted with the first magnetic attraction end to rotate and complete alignment.

[0008] Meanwhile, the structure can realize modular assembly, is simple in structure and convenient to assemble, simplifies the assembly process, and has fewer components, so that the machining cost is reduced.

[0009] Preferably, the first magnetic end includes a first magnet provided on the knob; the second magnetic end includes a second magnet provided on the mounting body and magnetically attracted to the adjacent first magnet.

[0010] Preferably, the second magnetic end further includes a third magnet provided on the mounting body and magnetically attracted to the adjacent first magnet. The first magnet is magnetically attracted to the second magnet and the third magnet respectively; the first magnet, the second magnet and the third magnet are provided, and after rotating the knob, the first magnet is driven to rotate around the axis until it approaches the second magnet or the third magnet, the first magnet is magnetically attracted, thereby driving the knob to rotate, so that the knob rotates to the target position, that is, the position where the second magnet is provided or the position where the third magnet is provided. This operation is simple and can effectively align the corresponding unlocking position and locking position.

[0011] Preferably, the second and third magnets are sequentially arranged on a single circular ring, with the axis of the positioning mechanism as the center, and the first magnet is projected onto the circular ring along the axial direction of the knob. The circumferentially arranged second and third magnets cooperate with the first magnet to achieve magnetic attraction and alignment. Because they are projected onto the circular ring, the rotational path of the first magnet overlaps with that of the circular ring, facilitating the first magnet approaching the second or third magnet to rotate the knob, thereby aligning the knob to the corresponding switch position and lock position.

[0012] Preferably, the first magnet is arranged on the side of the knob facing the positioning mechanism, and the second magnet and the third magnet are both arranged on the side of the mounting body facing the knob. The first magnetic end and the second magnetic end are arranged facing each other with a short distance to facilitate magnetic attraction.

[0013] Preferably, the first magnet is positioned at the edge of one side of the knob; the second and third magnets are positioned circumferentially around the edge of the positioning mechanism, with the center of the positioning mechanism as the center. Positioning the first, second, and third magnets at the edge allows the knob to automatically align at a wider angle, avoiding the situation where the knob is positioned close to the axis and automatically rotates to the target position at a smaller angle, thus increasing the adjustable margin.

[0014] Preferably, the first magnets are arranged in groups on the same straight line;

[0016] The third magnets are arranged in groups on the same straight line passing through the axis of the mounting body;

[0017] The second and third magnets are arranged circumferentially with the mounting body as the axis. The first, second and third magnets are arranged in groups, wherein the second magnets in the group are arranged vertically, corresponding to the unlocked state;

[0018] The third magnets arranged in groups are arranged horizontally, which corresponds to the locked state. By rotating the knob provided with the first magnets arranged on the same straight line, it is rotated to be magnetically attracted to the unlocked position or the locked position. Then, the knob is rotated to the target position due to the action of magnetic attraction, so that the target position of the knob is adapted to the second magnet setting position or the third magnet setting position.

[0019] Preferably, the connecting line of the second magnets and the connecting line of the third magnets are perpendicular to each other. The second magnets and the third magnets are arranged perpendicular to each other so that the knob can reach the unlocked position and the locked position with a certain interval to avoid mutual interference.

[0020] Preferably, the mounting body is provided with a matching groove that matches one side of the knob. Providing the matching groove is conducive to positioning the knob, reducing the difficulty of assembly work, improving production efficiency, streamlining the assembly process, involving fewer parts, and facilitating reduced processing costs.

[0021] Preferably, the mounting body is provided with a first section and a second section alternately arranged with its axis as the center of a circle at the second magnetic end;

[0022] The first interval is set at an angle of 40°; the second interval is set at an angle of 50°. The first interval corresponds to the line connecting the second magnet location and the axis of the mounting body, or the line connecting the third magnet location and the axis of the mounting body, as the axis of symmetry. When the knob is rotated to the first interval, it is effectively magnetically attracted and rotated to the unlocked or locked position, facilitating alignment and reset. The second interval is also set as a non-magnetic interval or a position where the magnetic attraction is weak and does not cause the knob to rotate, preventing accidental knob rotation when it is not required.

[0023] A door lock comprises a door lock knob reset mechanism as described above, a connecting shaft, and a door lock body connected to the door lock knob reset mechanism, wherein the door lock body is connected to the positioning mechanism, the knob is connected to the connecting shaft, and the connecting shaft is coaxially movably connected to the mounting body.

[0024] The knob is connected to the mounting body through a connecting shaft so that the knob is coaxially movably connected, which facilitates the rotation operation of the knob. At the same time, this structure can realize modular assembly, has a simple structure and is easy to assemble, streamlines the assembly process, involves fewer parts, and facilitates reducing processing costs.

[0036] In order to more clearly illustrate the technical scheme in the embodiment of the utility model or prior art, specific implementation ways of the utility model will be explained below with reference to the drawings. Obviously, the drawings in the following description are only some embodiments of the utility model, and for those skilled in the art, other drawings can be obtained according to these drawings without creative labor, and other implementation ways can be obtained.

[0037] The technical scheme of the utility model will be introduced in detail below with specific embodiments.

[0038] Referring to Figures 1 to 6 As shown in the figure, a door lock knob reset mechanism comprises a knob 1 and a positioning mechanism coaxially arranged with the knob 1 and movably connected.

[0039] The knob 1 is provided with a first magnetic end, and the positioning mechanism includes a mounting body 2 movably connected to the knob 1, and a second magnetic end disposed on the mounting body 2 and magnetically attracted to the first magnetic end so as to rotate and align the knob 1. The mounting body 2 and the corresponding first and second magnetic ends allow the knob 1 to rotate on the mounting body 2 and, when the first magnetic end rotates close to the second magnetic end, the knob 1 is rotated to the target position. This simple operation allows for effective alignment of the corresponding unlocked and locked positions.

[0040] At the same time, this structure can be assembled in a modular manner, has a simple structure and is easy to assemble, simplifies the assembly process, involves fewer parts, and is easy to reduce processing costs.

[0041] The first magnetic end includes a first magnet 11 disposed on the knob 1 ; the second magnetic end includes a second magnet 22 disposed on the mounting body 2 and magnetically attracted to the adjacent first magnet 11 .

[0042] The second magnetic end also includes a third magnet 23 provided on the mounting body 2 and magnetically attracted to the adjacent first magnet 11. The first magnet is magnetically attracted to the second magnet and the third magnet respectively; the first magnet 11, the second magnet 22 and the third magnet 23 are provided, and after rotating the knob 1, the first magnet 11 is driven to rotate around the axis until it approaches the second magnet 22 or the third magnet 23. The first magnet 11 is magnetically attracted and drives the knob 1 to rotate, so that the knob 1 rotates to the target position, that is, the position where the second magnet 22 or the third magnet 23 is provided. This operation is simple and can effectively align with the corresponding unlocking position and locking position.

[0043] The second and third magnets 22 and 23 are arranged sequentially on a circular ring, centered around the positioning mechanism's axis. The first magnet 11 is projected onto this ring along the knob's axial direction. The circumferentially arranged second and third magnets 22 and 23 cooperate with the first magnet 11 to achieve magnetic attraction and alignment. Because they are projected onto this circular ring, the rotational path of the first magnet 11 overlaps with that of the circular ring. This allows the first magnet 11 to approach the second and third magnets 22 and 23, rotating the knob 1 and aligning the knob to the corresponding open and close positions.

[0044] The first magnet 11 is disposed on the side of the knob 1 facing the positioning mechanism, and the second magnet 22 and the third magnet 23 are both disposed on the side of the mounting body 2 facing the knob 1. The first magnetic end and the second magnetic end are disposed opposite each other with a short distance to facilitate magnetic attraction.

[0045] The first magnet 11 is positioned at the edge of one side of the knob 1; the second and third magnets 22 and 23 are positioned around the edge of the positioning mechanism, circumferentially with the center of the positioning mechanism as the center. Positioning the first, second, and third magnets at the edges allows the knob to automatically align at larger angles, avoiding the situation where the knob is positioned close to the axis and automatically rotates to the target position at smaller angles, thus increasing the adjustable margin.

[0046] The first magnets 11 are arranged in groups on the same straight line;

[0047] The second magnets 22 are arranged in groups on the same straight line that passes through the axis of the mounting body 2;

[0048] The third magnets 23 are arranged in groups on the same straight line that passes through the axis of the mounting body 2;

[0049] The second magnet 22 and the third magnet 23 are arranged circumferentially with the mounting body 2 as the axis. The first magnet 11, the second magnet 22 and the third magnet 23 are arranged in groups, wherein the second magnet 22 is arranged vertically, which corresponds to the unlocked state;

[0050] The third magnets 23 arranged in groups are arranged horizontally, which corresponds to the locked state. By rotating the knob provided with the first magnets 11 arranged on the same straight line, it is rotated to be magnetically attracted to the unlocked position or the locked position. After that, the knob 1 is rotated to the target position due to the action of magnetic attraction, so that the target position of the knob is adapted to the setting position of the second magnet 22 or the setting position of the third magnet 23.

[0051] The connecting line of the second magnets 22 and the connecting line of the third magnets 23 are perpendicular to each other. The second magnets 22 and the third magnets 23 are arranged perpendicular to each other, so that the knob 1 has a certain interval between the unlocking position and the locking position to avoid mutual interference.

[0052] The mounting body 2 is provided with a matching groove 21 that matches one side of the knob 1. The matching groove 21 is provided to facilitate positioning of the knob 1, reduce the difficulty of assembly operation, improve production efficiency, streamline the assembly process, involve fewer parts, and facilitate reducing processing costs.

[0053] The mounting body 2 is provided with a first section 24 and a second section 25 alternately arranged with its axis as the center of the circle at the second magnetic end;

[0054] The first section 24 is set at an angle of 40°; the second section 25 is set at an angle of 50°. The first section corresponds to the line connecting the second magnet 22 and the axis of the mounting body 2, or the line connecting the third magnet 23 and the axis of the mounting body 2, as the axis of symmetry. When the knob 1 is rotated to the first section 24, it is effectively magnetically attracted and rotated to the unlocked or locked position, facilitating alignment and reset. The second section 25 is also set as a non-magnetic section or a section where the magnetic attraction is weak and does not cause the knob 1 to rotate, preventing accidental knob rotation when it is not needed.

[0055] A door lock includes a door lock knob reset mechanism, a connecting shaft 4, and a door lock body 3 connected to the door lock knob reset mechanism. The door lock body 3 is connected to the positioning mechanism, the knob 1 is connected to the connecting shaft 4, and the connecting shaft 4 is coaxially movably connected to the mounting body 2.

[0056] The knob 1 is connected to the mounting body 2 via a connecting shaft 4, so that the knob 1 is coaxially movably connected, facilitating the knob's rotation. This structure also allows for modular assembly, a simple structure, ease of assembly, streamlined assembly processes, fewer components involved, and reduced processing costs. Specifically, the connecting shaft 4 is movably connected to the knob 1 via a screw 5.

[0057] The cross section of the knob 1 facing the positioning mechanism is circular, and the cross section of the mounting groove 21 facing the knob 1 is correspondingly circular.

[0058] In this technical solution, the second magnets 22 are arranged vertically, and the third magnets 23 are arranged horizontally. The second magnets 22 are arranged in groups of two, and the third magnets 23 are arranged in groups of two. The second magnets 22 arranged vertically correspond to the unlocked state of the door lock, and the third magnets 23 arranged horizontally correspond to the locked state of the door lock. At the same time, the corresponding locked or unlocked positions can be adjusted according to actual production needs.

[0059] This technical solution can solve the problem of not being able to accurately return to the unlocked or locked position in the absence of a spring elastic device; at the same time, it can reduce processing costs when the requirements for component processing accuracy and assembly tolerance are relatively low; it can solve the problems of complex structures, numerous parts and components, and complicated production and assembly in the past, and can streamline the process.

[0060] The installation method is as follows:

[0061] The first magnet is mounted on the knob 1 to form a knob assembly;

[0062] The rear lock housing assembly, i.e. the door lock body, is mounted on the rear lock housing by the second magnet 22 and the third magnet 23 to realize the device;

[0063] The knob assembly is installed in the rear lock housing assembly, and the connecting shaft is installed on the reverse side and fixed by screws, which has a simple structure and low cost;

[0064] The implementation process is as follows:

[0065] The principle of precise knob reset: the knob is pre-installed with 2 magnets, and the corresponding slots of the rear lock shell are pre-installed with 4 magnets. Assuming that the knob is in the locked state at the beginning, that is, when the small dot of the knob is aligned with the locked icon of the rear lock shell, Figure 4 As shown; turn the knob clockwise or counterclockwise by hand. There are two ways to rotate the angle. In method 1, rotate the knob ① directly to 90° and then release your hand. Under the attraction of the magnet, the small dot on the knob will accurately align with the unlock icon of the rear lock shell; in method 2, rotate the knob 70° to 90° close to the unlock icon, that is, it is in the effective position of the first interval; then release your hand. Under the attraction of the magnet, the knob will automatically return to its original position and accurately align with the unlock icon of the rear lock shell, as shown Figure 5 As shown; this device uses the principle that magnets in the same direction repel each other and in opposite directions attract each other to solve the problem of door lock knob reset and inaccuracy.

[0066] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
