Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of door lock body, more particularly to a one-way control anti-lifting lock body structure. BACKGROUND

[0002] In order to simplify the locking step, there are many anti-lifting (uplifting) handles in the prior art to realize the locking of the lock body, for example, the anti-lifting locking lock body disclosed in the patent No. CN117052229B, both sides of the dial wheel are provided with rotationally connected square core pieces, the square core pieces on both sides are respectively connected with the inner handle and the outer handle on the door; the dial wheel is provided with a movable adapter, and the adapter has a first station and a second station, in the first station and when the square core piece rotates in the unlocking direction, the adapter is located on the unlocking rotation stroke of the square core piece and abuts against the square core piece to drive the rotation of the dial wheel; and the linkage part B can drive the adapter to move to the second station when the square core piece rotates in the locking direction, so that the adapter is separated from the unlocking rotation stroke of the square core piece.

[0003] However, it is found in use that the above-mentioned prior art still has some defects, first of all, the lock body of the above-mentioned patent can realize locking by anti-lifting (uplifting) of the outer handle or the inner handle, and such lock body structure is generally used for indoor magnetic attraction door locks, and the actual use of the indoor door is generally to lock by a person in the room, and a person outside the room rarely needs to lock. The existing structure often causes locking due to the anti-lifting misoperation of the outer handle, at this time, the person outside needs to use a key to open the door, which is relatively inconvenient. Secondly, there is another problem that the existing anti-lifting locking can be performed whether the door is open or closed, which corresponds to the magnetic attraction door lock, that is, the locking tongue does not affect the anti-lifting locking of the locking structure whether it is extended or retracted, which leads to that the door in the open state is easy to cause the lock body to be locked due to the anti-lifting misoperation, at this time, the door is automatically locked after being closed, the locking tongue is extended due to the magnetic attraction, and the door is automatically locked, but the locking at this time is not what the user expects.

[0004] Therefore, based on the above-mentioned problems in use, the present application is proposed to solve these problems, so that the use of the lock body is more in line with humanization, and the inconvenience caused by misoperation is avoided. SUMMARY

[0005] In view of the deficiencies of the prior art, the present application provides a one-way control anti-lifting lock body structure, the outer handle of which cannot be anti-lifted to lock, and the door cannot be anti-lifted to lock when it is not closed well, thereby avoiding the inconvenience caused by misoperation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a one-way controlled reverse lifting lock body structure, including a lock shell, a telescopic lock tongue and a driving component for driving the lock tongue inside the lock shell, characterized in that: the driving component includes a rotating dial and an inner chip and an outer chip rotatably disposed on both sides of the dial and respectively connected to the inner and outer handles, and the dial is provided with a lock block that can swing and abut or separate from the inner chip and the outer chip;

[0007] A transmission rod is provided between the inner and outer handles. The transmission rod includes an inner rod and an outer rod that rotate relative to each other. The inner rod connects the inner handle, the inner chip, and the dial, and makes the three rotate synchronously. The outer rod connects the outer handle and the outer chip, and makes the two rotate synchronously.

[0008] When the inner or outer handle is turned in the unlocking direction, the inner or outer chip can be driven to rotate the dial in the unlocking direction through the opposing lock block.

[0009] When the inner handle is rotated in the locking direction, the inner square lever drives the dial to rotate in the locking direction, causing the lock block to separate from both the inner and outer square chips.

[0010] The present invention is further configured such that: a blocking part is provided on the lock tongue, and a limiting part is provided on both the inner chip and the outer chip; when the lock tongue retracts into the lock housing, the blocking part abuts against the limiting part to prevent the inner chip and the outer chip from rotating in the locking direction.

[0011] The present invention is further configured such that: a fastening element is provided on the inner square rod, the fastening element being used to restrict the movement of the inner square rod in the axial direction.

[0012] The invention is further configured such that: a connecting rod is provided on the inner square rod, and the outer square rod is hollow, so that the connecting rod can pass through the outer square rod and extend to the outer handle; the outer handle is provided with a rotatable unlocking element, which is used to drive the connecting rod to rotate.

[0013] The present invention is further configured such that: the end of the connecting rod is provided with a special-shaped part, and the special-shaped part is circumferentially fixedly connected with the unlocking element.

[0014] The present invention is further configured such that: a switching pin is fixedly provided inside the lock housing, and an extension portion is provided on the lock block to abut against the switching pin; when the dial rotates in the locking direction, the switching pin drives the lock block to separate from the inner chip and the outer chip; when the dial rotates in the unlocking direction, the switching pin drives the lock block to abut against the inner chip and the outer chip.

[0015] The application is further provided with: the extension part includes a first end and a second end respectively located on both sides of the swing center of the lock block, so that when the first end and the switching pin abut and the second end and the switching pin abut, the lock block has opposite swing directions.

[0016] The application is further provided with: the lock block is provided with a telescopic clamping bead, and the dial is provided with two positioning grooves matched with the telescopic clamping bead, and the two positioning grooves correspond to the positions of the lock block when abutting against or separating from the inner square chip and the outer square chip respectively.

[0017] The application is further provided with: the lock shell is provided with a stroke limiting groove, and the inner square chip and the outer square chip are provided with protruding clamping blocks matched with the limiting groove, for restricting the rotation stroke of the inner square chip and the outer square chip.

[0018] In summary, the application has the following beneficial effects:

[0019] Compared with the prior art, the lock block relies on the rotation of the dial and the cooperation with the switching pin to realize the abutment or separation of the lock block and the inner square chip and the outer square chip, and the advantage is that the swing of the lock block is not driven by the inner square chip or the outer square chip, but relies on the cooperation of the dial and the switching pin, so that the inner square rod is connected with the inner handle, the inner square chip and the dial to be reversely lifted and locked, and the outer handle cannot be reversely lifted and locked, thereby avoiding misoperation.

[0020] Meanwhile, the application is also provided with a blocking part and a limiting part, so that when the lock tongue is located in the lock shell, the inner handle and the outer handle cannot be reversely lifted and locked, and the lock tongue must be extended after the door is closed, and then the inner handle and the outer handle can be reversely lifted and locked, and the advantage is that the door cannot be automatically locked after being closed due to misoperation when the door is opened, and when the door is closed but not completely closed and the lock tongue is not extended, the inner handle and the outer handle cannot be reversely lifted, thereby reminding the user that the door is not closed.

DETAILED DESCRIPTION

[0032] The application will be further described in detail below with reference to the drawings.

[0033] The embodiment discloses a one-way controlled anti-pulling lock body structure, as shown in the drawings, comprising a lock shell 1, a telescopic lock tongue 2 and a driving part 3 for driving the lock tongue 2 are arranged in the lock shell 1, the lock body structure is preferably applied to a magnetic lock body, the lock tongue 2 has a magnet, when the lock tongue 2 reaches the position of the door lock box, the lock tongue 2 is automatically stretched out under the action of the magnetic force, the driving part 3 is used for driving the lock tongue 2 to retract and realizing anti-pulling locking. Figures 1-10 In the embodiment, the driving part 3 comprises a dial 301 rotatably arranged and inner square chips 302 and outer square chips 303 rotatably arranged on both sides of the dial 301 and connected with inner and outer handles (not shown in the drawings), and the specific structure can be referred to Figure 7 A dial block 12 is arranged on the dial 301, a moving groove 13 is arranged on the lock tongue 2, and the movement of the lock tongue 2 is realized through the cooperation of the dial block 12 and the moving groove 13. In order to further realize the anti-pulling locking function, the dial 301 is provided with a lock block 4 capable of swinging and abutting or separating with the inner square chip 302 and the outer square chip 303, and the specific structure can be referred to Figure 2, transmission square rod 5 is arranged between the inner handle and the outer handle, the transmission square rod 5 includes inner square rod 51 and outer square rod 52 which rotate with each other, wherein the inner square rod 51 is connected with the inner handle, the inner square core 302 and the dial 301 and makes the three synchronous rotation, the outer square rod 52 is connected with the outer handle and the outer square core 303 and makes the two synchronous rotation; after cooperating with the locking block 4, when the inner handle or the outer handle rotates in the unlocking direction, the inner square core 302 or the outer square core 303 rotates synchronously, referring to Figure 3 and Figure 7 , the inner square core 302 and the outer square core 303 can drive the dial 301 to rotate in the unlocking direction after rotating through the abutting locking block 4; wherein the unlocking direction is the rotating direction when the inner handle and the outer handle are pressed down, and specifically to Figure 3 , the inner square core 302 rotates clockwise, Figure 7 , the outer square core 303 rotates counterclockwise.

[0034] referring to Figure 2 and Figures 4-5 , when the inner handle rotates in the locking direction, the inner square core 302 rotates synchronously, and the dial 301 can also rotate in the locking direction through the inner square rod 51, and the locking block 4 is separated from the inner square core 302 and the outer square core 303. Wherein the locking direction is the rotating direction when the inner handle is pulled up (upwardly pulled), and specifically to Figure 4 , the inner square core 302 rotates counterclockwise. After the handle is reset, the locking block 4 is in the state of Figure 5 and Figure 6 , the outer square core 303 is in idle rotation at this time, so the outer handle cannot open the door, and the door is in the locked state, and the inner handle can still drive the dial 301 to rotate due to the existence of the inner square rod 51, as shown in Figure 9 , in the process of rotating the dial 301, the locking block 4 will swing upward again and reset to the state of Figure 3 .

[0035] Through the design of the above structure, the inner handle of the present application can normally pull up and lock in reverse and press down and unlock, while the outer handle cannot pull up and lock in reverse, and can normally press down and unlock when unlocking, and cannot open the door after locking. It is more suitable for the application scene of indoor door, which greatly avoids the inconvenience caused by the outer handle that can pull up and lock in reverse.

[0036] Further, as the existing door has two directions of left opening and right opening, in order to improve the versatility, the inner square chip and the outer square chip have the same structure, and the division of the inner and outer is determined according to the actual room, the inner square rod 51 is installed on the side of the room, and the square chip on the side becomes the inner square chip, and the square chip on the other side naturally becomes the outer square chip. The advantage of the present application is that the segmented transmission square rod 5 is used for transmission, the inner square rod 51 synchronously drives the inner square chip 302 and the dial 301, and the position of the lock block 4 is changed by relying on the dial 301. The traditional reverse lifting locking structure is driven by the square chip to drive the similar lock block structure, and because the room door has two forms of left opening and right opening, the direction of the lock body structure needs to be adjusted, so the inner and outer square chips need to be made into a symmetrical structure. If the similar lock block structure is directly driven by the square chip to swing, because the inner and outer square chip structures need to be symmetrical, the outer handle can also realize reverse lifting locking, which is not expected in the present application. Therefore, the present application changes the thinking, relies on the segmented transmission square rod 5 to drive the dial 301 to swing the lock block 4, which avoids this problem. Thus, the present application realizes that the outer handle cannot reverse lifting locking on the basis of meeting the flexible adjustment versatility of the left opening door and the right opening door. This cannot be realized by the traditional reverse lifting locking door lock.

[0037] Further, referring to Figures 3-4 , the blocking portion 201 is arranged on the lock tongue 2, and the limiting portion 11 is arranged on the inner square chip 302 and the outer square chip 303. When the lock tongue 2 is retracted into the lock shell 1, the blocking portion 201 abuts against the limiting portion 11 to hinder the rotation of the inner square chip 302 and the outer square chip 303 in the locking direction. Figure 3 In the state shown in FIG. 6, the lock tongue 2 is in the retracted state, and obviously the inner square chip 201 cannot be rotated in the locking direction. Figure 4 In the state shown in FIG. 7, the lock tongue 2 is extended, and obviously the door has been closed. The lock tongue 2 is extended under the action of the magnetic force, the positions of the blocking portion 201 and the limiting portion 11 are disengaged, and the inner square chip 302 can be rotated in the locking direction, so as to realize locking.

[0038] The present application avoids the problem that the door is locked in advance due to the reverse lifting of the inner handle when the door is not closed, and the door is automatically locked when the door is closed and the lock tongue 2 is extended. The locking at this time is not expected by the user, but is caused by the misoperation. The advantage of the present application is that the door must be closed and the lock tongue must be extended before locking, so as to effectively solve the problem. At the same time, when the user closes the door but does not completely close it, the lock tongue is not extended, and the reverse lifting cannot be performed. Thus, the user is reminded that the door is not closed, and the safety is improved.

[0039] Further, referring to Figure 10The inner square rod 51 is provided with a buckle member 512, which cooperates with an external limiting member (not shown in the figure), for example, a spring pin, which does not hinder the circumferential rotation of the inner square rod 51, and only limits the axial position of the inner square rod 51. The inner square rod 51 is provided with a connecting rod 511, and the outer square rod 52 is hollow, so that the connecting rod 511 can pass out of the outer square rod 52 and extend to the outer handle, and the outer handle is provided with a rotatable unlocking element (not shown in the figure), which is used to drive the connecting rod 511 to rotate. In order to realize the unlocking outside the door, the outer handle is provided with a rotatable unlocking element, which can drive the connecting rod 511 to rotate, and in turn drive the inner square rod 51 and the dial 301 to rotate. This unlocking element can be a key cylinder, when a key is inserted outside the door, the inner square rod 51 can be directly driven to rotate, thereby driving the dial 301 to rotate, realizing that the door can also be unlocked with a key outside. As a further optimization, the end of the connecting rod 511 is provided with a special-shaped part 5111, which is circumferentially fixedly connected with the unlocking element. The special-shaped part 5111 can be square, triangular, or any structure with a part protruding, which can realize circumferential transmission, of course, the unlocking element can also be a screwdriver or other tool to realize rotation unlocking.

[0040] Further, in order to realize the above-mentioned dependence on the dial 301 to drive the lock block 4 to swing, the present application is fixedly provided with a switching pin 7 in the lock shell 1, and the lock block 4 is provided with an extension part 401 which abuts against the switching pin 7, referring to Figure 4 When the dial 301 rotates in the locking direction, the switching pin 7 drives the lock block 4 to separate from the inner square core 302 and the outer square core 303; referring to Figure 9 、 Figure 5 and Figure 3 When the dial 301 rotates in the unlocking direction, the switching pin 7 drives the lock block 4 to abut against the inner square core 302 and the outer square core 303. The extension part 401 includes a first end 4011 and a second end 4012 located on both sides of the swing center of the lock block 4, so that when the first end 4011 and the second end 4012 abut against the switching pin 7, the lock block 4 has opposite swing directions. Specifically, since the first end 4011 and the second end 4012 are located on both sides of the swing center, when the first end 4011 is subjected to the upward force of the switching pin 7, the lock block will swing downward to realize separation, and when the second end 4012 is subjected to the upward force of the switching pin 7, the lock block will swing upward to realize abutment. The present application makes the different ends of the lock block 4 act on the switching pin 7, so that the lock block 4 cooperates with the dial 301 to have different swing directions.

[0041] Further, in order to guarantee the stability of the position of the lock block 4 after swinging, the lock block 4 is provided with a telescopic clamping bead 402, and a spring cavity can be arranged in the lock block 4, the telescopic clamping bead 402 simply adopts a spring and a steel ball, the spring and the steel ball are installed in the spring cavity, and the steel ball part is extended out of the lock block, and meanwhile, the upper portion of the dial 301 is provided with two positioning grooves 3011 matched with the telescopic clamping bead 402, and the two positioning grooves 3011 correspond to the positions of the lock block 4 when the inner square chip 302 and the outer square chip 303 abut or separate.

[0042] Further, in order to constrain the rotating stroke of the inner square chip 302, the outer square chip 303 and the inner and outer handles, the lock shell 1 is provided with a stroke limiting groove 9, the inner square chip 302 and the outer square chip 303 are provided with protruding clamping blocks 10, and the clamping blocks 10 are matched with the limiting groove 9.
