Description

Technical Field

[0001] The utility model relates to the technical field of locks, and in particular to a lock body structure and a door lock. Background Art

[0002] A door lock is usually provided with an anti-lock knob. When the door leaf is closed, the anti-lock knob is turned in a preset direction, and the rotation of the door handle is restricted, that is, it is in an anti-lock state. However, the connection structure between the anti-lock knob and the handle in the existing door lock is relatively complex and has poor stability. When in use, the connection structure is prone to misalignment and other faults, affecting the anti-lock function. In addition, for some locks, such as locks with a single magnetic lock tongue, or locks with multiple lock tongues with an anti-lock lock tongue, when in use, if the door leaf is in an open state, the lock tongue related to the anti-lock function will usually retract into the inside of the lock. At this time, if someone mistakenly turns the anti-lock knob, the door handle will not be able to rotate, thereby affecting the normal use of the door lock. Utility Model Content

The same reference numerals in the figures represent the same or similar parts, and thus their repeated descriptions will be omitted. It should be noted that in the present disclosure, the terms "including", "configured with", and "set in" are used to express the meaning of open-ended inclusion, and mean that in addition to the listed elements / components / etc., there may be other elements / components / etc.; the terms "first", "second", etc. are only used as marks, and are not restrictions on the number or order of their objects; the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0026] Unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0027] In this embodiment, a lock body structure is disclosed. Please refer to Figures 1 to 4 The lock structure includes: a housing 1, a lock tongue 2, a lock tongue slider 3, an inner nut 5, an outer nut 6 and a locking block 4. The housing 1 can be formed by buckling two parts, and a space for accommodating other components is formed in the middle. Only one half of the housing 1 is shown in each figure to show its internal structure. A lock tongue hole is provided on one side of the housing 1, and the lock tongue 2 is slidably arranged on the side. The lock tongue 2 is retracted in the lock tongue hole to realize unlocking and locking.

[0028] The lock tongue slider 3 is slidably disposed in the housing 1, one end of which is connected to the lock tongue 2 and slides synchronously with the lock tongue 2, and an unlocking portion 31 is formed on the side of the lock tongue slider 3. The sliding assembly between the lock tongue slider 3 and the housing 1 and the sliding assembly between other structures in the following text can be realized by using structures such as slide grooves, slide rails, and slide rods in the prior art, and the details are not repeated. In this embodiment, the lock tongue 2 is a magnetic tongue, which can slide to the outside of the housing 1 when it is opposite to the lock tongue buckle box 10 with a magnet. Specifically, when it is opposite to the lock tongue buckle box 10, it can be attracted by the magnet in the lock tongue buckle box 10 and automatically move to the lock tongue buckle box 10 to achieve locking.

[0029] The inner and outer handles 5 and 6 are coaxially rotatably arranged in the housing 1, and can be connected to the handle of the door when in use, and the user can rotate the two handle handles through the handle. The inner and outer handles 5 and 6 will face the inner and outer sides of the door leaf respectively when actually installed, and are respectively connected to the inner handle and the outer handle, and the user can rotate one of the handles inside or outside the door.

[0030] The outer periphery of the inner peach 5 is formed with a first projection 51 opposite to the unlocking portion 31. When the unlocking portion 31 is in the locked state, the unlocking portion 31 is on the rotation path of the first projection 51 along the first direction. At this time, the inner peach 5 is rotated in the first direction, and the first projection 51 can abut against the unlocking portion 31, thereby driving the lock tongue slider 3 to slide toward the unlocking side to achieve unlocking. The outer periphery of the outer peach 6 is annularly formed with a second projection 61 and a third projection 62, wherein the second projection 61 is opposite to the unlocking portion 31. When the unlocking portion 31 is in the locked state, the unlocking portion 31 is on the rotation path of the second projection 61 along the first direction. At this time, the outer peach 6 is rotated in the first direction, and the second projection 61 can abut against the unlocking portion 31, thereby driving the lock tongue slider 3 to slide toward the unlocking side to achieve unlocking.

[0031] The locking block 4 is rotatably disposed in the housing 1, and a fourth protrusion 41 is formed on its outer periphery. The fourth protrusion 41 is located on the rotation path of the first protrusion 51 along the second direction, and is located on the rotation path of the third protrusion 62 along the first direction. When the inner detent 5 rotates along the second direction, the first protrusion 51 abuts against the side of the fourth protrusion 41, driving the locking block 4 to rotate along the first direction, and then the end face of the fourth protrusion 41 abuts against the side of the third protrusion 62. At this time, the length direction of the fourth protrusion 41 is the tangential direction of the outer detent 6, which can limit the rotation of the outer detent 6.

[0032] For details, please refer to Figures 2a to 3c , Figure 2a The lock body structure is in the initial unlocking state, wherein the lock tongue 2 is retracted into the housing 1, and the lock tongue slider 3 slides to the right side of the housing 1. When the lock tongue 2 is moved into the lock tongue buckle box 10, the lock tongue slider 3 moves to the left, and finally presents Figure 2b In the state shown in FIG. 1 , the unlocking portion 31 is opposite to the first protrusion 51 and the second protrusion 61. If the inner plunger 5 is rotated clockwise, the first protrusion 51 abuts against the unlocking portion 31 and drives the lock tongue slider 3 to slide rightward, and the lock tongue 2 is moved into the housing 1, and the lock is unlocked; if the outer plunger 6 is rotated clockwise, the second protrusion 61 abuts against the unlocking portion 31 and drives the lock tongue slider 3 to slide rightward, and the lock tongue 2 is moved into the housing 1, and the lock is unlocked as well. Figure 2c That is, the process of unlocking by rotating the outer peach 6 clockwise is shown.

[0033] In the locked state, the lock structure can be locked by turning the inner lever 5 counterclockwise, and the outer lever 6 cannot be turned clockwise to unlock it. Figure 3aWhen the inner peach 5 rotates counterclockwise, the first protrusion 51 abuts against the side of the fourth protrusion 41, driving the locking block 4 to rotate clockwise, and the end face of the corresponding fourth protrusion 41 rotates to the side of the third protrusion 62. At this time, when the outer peach 6 rotates clockwise, the third protrusion 62 abuts against the end face of the fourth protrusion 41, and cannot drive the locking block 4 to rotate. Therefore, the outer peach 6 cannot rotate clockwise either, that is, reverse locking is achieved.

[0034] In the reverse locking state, since the locking block 4 only limits the outer peach 6, the lock can also be unlocked by rotating the inner peach 5 clockwise.

[0035] The lock body structure in this embodiment eliminates the anti-locking knob in the traditional door lock, and directly utilizes the cooperation between the inner peach 5 and the locking block 4, and the anti-locking and unlocking functions can be realized when the inner peach 5 is rotated forward / reverse. The structure inside the lock body is simplified, the stability of the lock body during operation is improved, and the lock body structure can be ensured to operate stably for a long time.

[0036] In this embodiment, the fourth projection 41 is arranged on the lower side of the first projection 51 and the upper side of the third projection 62, so that when the inner peach 5 is rotated counterclockwise, the locking block 4 can be driven to rotate clockwise to limit the outer peach 6. Correspondingly, the above-mentioned first direction refers to the clockwise direction in the accompanying drawings, and the second direction refers to the counterclockwise direction in the accompanying drawings. In other embodiments, the positional relationship between the inner peach 5, the outer peach 6 and the locking block 4 can also be changed according to actual needs, and when finally unlocking and locking, the inner peach 5 is also rotated in two opposite directions.

[0037] It should be noted that when the lock body structure is in the unlocked state, that is, when the lock tongue 2 moves into the housing 1, if the inner peach 5 is rotated counterclockwise in the above manner, the lock body structure will also be in the reverse locked state. At this time, the outer peach 6 and the outer handle connected thereto will not be able to rotate, affecting the normal use of the lock body structure. For this reason, a fifth projection 52 is also formed on the inner peach 5, and a limited position portion 32 is formed on the lock tongue slider 3. When the lock tongue 2 enters the housing 1 with the lock tongue slider 3, the limited position portion 32 abuts against the fifth projection 52, restricting the rotation of the inner peach 5 in the counterclockwise direction, and then reverse locking cannot be achieved. In other words, when the lock tongue 2 moves into the housing 1, the lock body structure cannot be placed in the reverse locked state by rotating the inner peach 5, thereby avoiding the phenomenon of reverse locking caused by mistaken operation by the user when the door leaf is opened.

[0038] Furthermore, in this embodiment, an unlocking push rod 7 is also provided in the housing 1, which is used to release the locked state when the inner handle is unlocked in the locked state. Figure 3b and Figure 3cThe unlocking push rod 7 is synchronously slidably arranged in the housing 1 with the lock tongue slider 3, and its left end is fixedly connected to the lock tongue 2. A sixth protrusion 42 is formed on the outer periphery of the locking block 4. In the reverse locking state, the rotation of the outer peach 6 is limited. At this time, when the inner peach 5 is unlocked by rotating clockwise, the unlocking push rod 7 will be driven by the lock tongue 2 to move to the unlocking side (i.e., the right side in the figure), and abut against the side of the sixth protrusion 42, driving the locking block 4 to rotate counterclockwise so that the fourth protrusion 41 is away from the third protrusion 62, and finally reaches the side of the first protrusion 51, i.e. Figure 3c At this moment, the rotation restriction of the outer peach 6 is released, and the locking block 4 returns to the initial position simultaneously, and the subsequent inner peach 5 rotates counterclockwise to continue to realize the anti-locking.

[0039] In other embodiments, the setting positions of the unlocking push rod 7, the locking block 4, and the sixth protrusion 42 can also be changed according to actual needs. It is only necessary to ensure that the unlocking push rod 7 can abut against the side of the sixth protrusion 42 when moving toward the unlocking side, and drive the locking block 4 to rotate so that the fourth protrusion 41 is away from the third protrusion 62, so that the inner lever 5 can be used to simultaneously achieve unlocking and releasing the anti-lock.

[0040] In this embodiment, an unlocking peach 8 is rotatably provided between the inner peach 5 and the outer peach 6, and it rotates coaxially with the inner peach 5. An unlocking groove 82 is formed at the axis of the unlocking peach 8, and a groove 81 is formed on one side of the unlocking peach 8 and is sleeved on the fourth protrusion 41, so that the unlocking peach 8 and the locking block 4 can rotate synchronously, that is, the two can be regarded as meshing and connected together. A through hole opposite to the unlocking groove 82 is provided on the outer peach 6. The user can use a preset tool on the outside to extend into the unlocking groove 82 in the housing 1 to rotate the unlocking peach 8, and then rotate the locking block 4 to make the fourth protrusion 41 away from the third protrusion 62, so as to release the reverse lock.

[0041] Figure 4 The process of emergency unlocking by unlocking the peach 8 is shown. Figure 3a By comparing the reverse locking state shown, it can be seen that rotating the unlocking lever 8 clockwise can cause the locking block 4 to rotate counterclockwise, and then the fourth protrusion 41 moves away from the third protrusion 62 and reaches the side of the first protrusion 51, thereby releasing the reverse locking state.

[0042] In addition, in this embodiment, a return spring 9 is further provided in the housing 1, the left end of which is connected to the lock tongue 2, and indirectly applies a force toward the unlocking side to the lock tongue slider 3. Figure 2a and Figure 2b As shown, the return spring 9 applies a force toward the right to the lock tongue slider 3. When the lock tongue 2 and the lock tongue slider 3 are not subjected to other external forces, the return spring 9 can pull the lock tongue 2 into the housing 1 to prevent the lock tongue 2 from colliding with the user or other objects.

[0043] For the lock body structure in this embodiment, there are two paddles connected to the handle, instead of sharing one paddle for the inner and outer handles. Therefore, the inner and outer handles connected to the paddles can rotate independently. During actual installation, there are left-opening and right-opening forms of the door leaf. Correspondingly, the inner paddle 5 in the lock body structure will be on the inner and outer sides of the door leaf respectively in these two situations. The realization of the above functions is achieved by connecting the inner paddle 5 to the inner handle. If it is directly connected to the outer handle, the above functions cannot be achieved. Therefore, in order to ensure that the lock body structure can be applied to both left-opening and right-opening door leaves, specific improvements are made to the structures of the inner paddle 5 and the outer paddle 6. Please refer to the following for details. Figure 1 A seventh protrusion 53 is formed on the inner clutch 5 and is opposite to the third protrusion 62. An inner abutment portion 511 protruding toward the outward clutch 6 is formed axially on the first protrusion 51. An outer abutment portion 611 protruding toward the inward clutch 5 is formed axially on the second protrusion 61. The locking block 4 is axially slidably arranged in the housing 1. The user can adjust the position of the locking block 4 according to the actual opening direction of the door leaf.

[0044] Specifically, in this embodiment, the fourth protrusion 41 is located on the rotation path of the inner abutment portion 511 and the third protrusion 62. When the inner shifting peach 5 is rotated counterclockwise, the inner abutment portion 511 thereon drives the locking block 4 to rotate, and then the fourth protrusion 41 abuts against the third protrusion 62 to limit the rotation of the outer shifting peach 6. In this structural form, the inner shifting peach 5 of the lock body structure is arranged on the inner side close to the door leaf, and the outer shifting peach 6 is arranged on the outer side close to the door leaf.

[0045] When it is necessary to arrange the inner lever 5 near the outer side of the door leaf and the outer lever 6 near the inner side of the door leaf to adapt to the door opening direction, the user only needs to slide the locking block 4 axially so that the fourth protrusion 41 thereon is in the rotation path of the outer abutment portion 611 and the seventh protrusion 53. At this time, the outer lever 6 is rotated counterclockwise, and the outer abutment portion 611 thereon drives the locking block 4 to rotate, and then the fourth protrusion 41 abuts against the seventh protrusion 53 to limit the rotation of the inner lever 5, and the reverse locking function can also be realized on the inner side of the door.

[0046] It should be noted that the relevant structure for realizing the axial sliding of the locking block 4 is not the innovation of this technical solution, and the relevant structure already exists in the prior art, such as opening a through hole on the shell 1, and then using a tool to push the locking block 4 to move, so the relevant structure will not be described in detail.

[0047] In addition, in this embodiment, a door lock is also disclosed, comprising the above-mentioned lock body structure, an inner handle and an outer handle. One end of the inner handle passes through the housing 1 and is connected to the inner lever 5, and one end of the outer handle passes through the housing 1 and is connected to the outer lever 6. The user can rotate the inner lever 5 by rotating the inner handle, and rotate the outer handle to rotate the outer lever 6, so as to realize various functions in the above-mentioned lock body structure.

[0048] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
