Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1:

[0025] Reference Figures 1-3 This utility model provides a bolt locking point structure for an integrated lock on a security door, comprising:

[0026] The first pin locking point transmission box 4 is located at the top or bottom of the inner side wall of the door body 1. The first transmission rod 41 is vertically slidably arranged inside the first pin locking point transmission box 4 and is provided with a reverse transmission structure. The input end of the reverse transmission structure is connected to the main lock box 3 through the transmission bar 2, and the output end of the reverse transmission structure is connected to the first transmission rod 41. The end of the first transmission rod 41 is fixedly connected with a locking point 6 for inserting into the door frame.

[0027] The second pin locking point transmission box 5 is located at the top or bottom of the inner side wall of the door body 1. The second pin locking point transmission box 5 is vertically slidably connected to the second transmission rod 51 and is provided with a co-directional transmission structure. The input end of the co-directional transmission structure is connected to the main lock box 3 through the transmission bar 2, and the output end of the co-directional transmission structure is connected to the second transmission rod 51. The end of the second transmission rod 51 is fixedly connected to a locking point 6 for insertion into the door frame.

[0028] The main function of the reverse transmission mechanism is to link the main lock box 3 and the first transmission rod 41, so that when the main lock box 3 drives the transmission bar 2 to move, the first transmission rod 41 can move in the opposite direction to the transmission bar 2, realizing the linkage between the main lock box 3 and the first transmission rod 41. The main function of the same-direction transmission mechanism is to link the main lock box 3 and the second transmission rod 51, so that when the main lock box 3 drives the transmission bar 2 to move, the second transmission rod 51 can move in the same direction as the transmission bar 2, realizing the linkage between the main lock box 3 and the second transmission rod 51. Overall, this utility model provides a structure for a first pin lock point transmission box and a second pin lock point transmission box, enabling existing integrated locks on the market to quickly achieve transmission connection with the reverse transmission mechanism and the same-direction transmission mechanism. This allows for quick and convenient installation of top and bottom locking points inside any door, without the need to develop new lock bodies, reducing costs while increasing the security of the anti-theft door.

[0029] Further optimization of the scheme: the reverse transmission structure includes a rocker plate 42, the middle of which is hinged to the first pin locking point transmission box 4. The two ends of the rocker plate 42 are respectively provided with first slots 46. The first transmission mechanism is provided on the side of the first pin locking point transmission box 4 away from the first transmission rod 41. The end of the first transmission rod 41 away from the locking point 6 and the first transmission mechanism are respectively fixedly connected with first pins 45. The two first pins 45 are respectively hinged in the two first slots 46.

[0030] In a further optimized scheme, the first transmission mechanism includes a first movable plate 43 that is vertically slidably connected to the first pin locking point transmission box 4, a first pin 45 that is fixedly connected to the first movable plate 43, the first movable plate 43 and the first transmission rod 41 are respectively located at both ends of the rocker plate 42, a first slot 44 is provided on the side of the first movable plate 43 away from the rocker plate 42, one end of the transmission bar 2 is fixedly connected in the first slot 44, and the other end of the transmission bar 2 is connected to the main lock box 3.

[0031] like Figure 1 and Figure 2 As shown, in this embodiment, the entire transmission bar 2 is linked with the main lock box 3. When the door needs to be locked, the main lock box 3 pushes the transmission bar 2 down. The downward movement of the transmission bar 2 causes the first moving plate 43 to move down. At the same time, the first moving plate 43 presses down on one end of the rocker plate 42, causing the other end of the rocker plate 42 to lift the first transmission rod 41, raising the locking point 6 to the door frame to achieve the door locking effect.

[0032] Further optimization of the scheme: the co-directional transmission structure includes a first rocker section and a second rocker section connected by transmission. The first rocker section includes a first secondary rocker 52, the middle of which is hinged to the second pin locking point transmission box 5. One end of the first secondary rocker 52 is provided with a second slot 56, and the other end of the first secondary rocker 52 is fixedly connected to a third pin 58. A second transmission mechanism is provided on the side of the second pin locking point transmission box 5 away from the second transmission rod 51. The second slot 56 is connected to the second transmission mechanism by transmission, and the third pin 58 is connected to the second rocker section by transmission.

[0033] The scheme is further optimized. The second rocker section includes a second secondary rocker 57. The middle part of the second secondary rocker 57 is hinged in the second pin locking point transmission box 5. The two ends of the second secondary rocker 57 are respectively provided with third slots 59. The end of the second transmission rod 51 away from the locking point 6 is fixedly connected to a second pin 55. The second pin 55 and the third pin 58 are respectively hinged in the two third slots 59.

[0034] The scheme is further optimized. The second transmission mechanism includes a second moving plate 53 that is vertically slidably connected inside the second pin locking point transmission box 5. The second moving plate 53 and the second transmission rod 51 are located on the two sides inside the second pin locking point transmission box 5, respectively. A fourth pin 510 is fixedly connected to the second moving plate 53. The fourth pin 510 is hinged in the second slot 56. A second slot 54 is opened on the side of the second moving plate 53 away from the first auxiliary rocker plate 52. One end of the transmission bar 2 is fixedly connected in the second slot 54. The other end of the transmission bar 2 is connected to the main lock box 3.

[0035] like Figure 1 and Figure 3 As shown, when the door needs to be locked, the main lock box 3 pushes the transmission bar 2 downward, and the downward movement of the transmission bar 2 drives the second moving plate 53 downward. At the same time, the second moving plate 53 presses down on one end of the first auxiliary rocker 52, causing the other end of the first auxiliary rocker 52 to rise and lift the left end of the second auxiliary rocker 57. Meanwhile, the right end of the second auxiliary rocker 57 moves down, and the locking point 6 is lowered to the door frame by moving the second transmission rod 51 downward, thus achieving the door locking effect.

[0036] Example 2:

[0037] An anti-theft door includes the aforementioned anti-theft door integrated lock pin locking point structure. When the transmission bar 2 is a whole piece that moves up and down with the main lock box 3, the top and bottom of the door body 1 are respectively fixedly connected to the first pin locking point transmission box 4 and the second pin locking point transmission box 5, and the two ends of the transmission bar 2 are respectively connected to the reverse transmission structure and the same direction transmission structure.

[0038] like Figure 4As shown, when the main lock box 3 locks the door, it simultaneously pulls the upper and lower transmission bars 2 towards the middle. At this time, the first pin locking point transmission box 4 is installed at the top and bottom of the door body 1, respectively. Thus, when the door is locked, the transmission bar 2 moves towards the middle, pulling the first transmission rod 41 out of the door body 1 and inserting it into the door frame to achieve the locking effect.

[0039] Example 3:

[0040] The difference between this embodiment and embodiment two is that when the transmission bar 2 is set to be two bars, one above the other, that move simultaneously with the main lock box 3 when they retract or expand, the top and bottom of the door body 1 are respectively fixedly connected to the first pin locking point transmission box 4 or the second pin locking point transmission box 5, and the two ends of the two transmission bars 2 are respectively connected to two sets of reverse transmission structures or two sets of same-direction transmission structures.

[0041] like Figure 5 As shown, when the main lock box 3 locks the door, it simultaneously pushes the upper and lower transmission bars 2 to both sides. At this time, the second pin locking point transmission box 5 is installed at the top and bottom of the door body 1, respectively. Thus, when the door is locked, the transmission bars 2 move to both sides, pushing the first transmission rod 41 out of the door body 1 and into the door frame to achieve the locking effect.
