Description

Technical Field

[0001] The utility model relates to a safe box door locking structure, in particular to an integrated door locking structure of a small safe deposit box. Background Art

[0002] The existing safe door locking structure includes a driving device arranged on the door panel and a door lock structure that closes and opens the door through the driving device. The door lock structure generally includes a slide plate, a latch connected to the slide plate, a lock for locking the slide plate, a driving structure for driving the slide plate to move, and other components. The assembly relationship is complicated, and the overall cost of the latch structure is high. For the safe door used in daily life, how to improve its economical and practical use is a problem that ordinary families are more concerned about.

[0003] For example, a Chinese utility model patent "Four-sided bolting mechanism for safe door" with patent number ZL200920117151.X (publication number CN201381698Y) discloses such a mechanism, including a door panel, a front slide connected with a front bolt head, an upper slide connected with an upper bolt head at the upper end, and a lower slide connected with a lower bolt head at the lower end; the front end of the connecting plate is connected to the front slide via a front transmission pin, and the rear end of the connecting plate is connected to the rear slide via a rear transmission pin. A driving mechanism for driving the front slide to move horizontally is provided on the door panel, and the driving mechanism for driving the front slide to move horizontally is: a shift fork which is rotatably arranged on the back of the door panel and driven to rotate by a key or a handle, and the other end of the shift fork is hinged to the waist-shaped hole on the front slide via a driving pin. Looking at the existing safe door lock structure, the slide, lock, and drive structure are all directly and scatteredly arranged on the door panel. Because the door panel is large and bulky, if the slide, lock, drive structure and other components are directly assembled on the door panel, the assembly and processing are relatively complicated. Furthermore, in the existing fork transmission mode, the fork must be arranged beside the front slide plate, which will cause the entire latch structure to be not compact and not suitable for small safe deposit boxes. In addition, the fork transmission has poor stability, is easily stuck, and is laborious to transmit.

[0004] In summary, the existing door lock structure is not suitable for small safe deposit boxes. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide an integrated door lock structure for a small safe deposit box in which a slide plate, a lock and a driving structure are integrated and none of them are directly arranged on the box door in view of the above-mentioned existing technical status.

[0006] The technical solution adopted by the utility model to solve the above technical problems is: an integrated door lock structure of a small safe deposit box, including a slide plate with a bolt head at the right end, a lock and a slide plate driving structure, characterized in that it also includes a cover for fixing to the back of the box door, the cover has a mounting cavity with an open lower end, the slide plate is constrained in the inner bottom surface of the cover and can move left and right, a through hole for the bolt head to pass through is opened on the right side wall of the cover, and the lock and the driving structure are both installed on the inner bottom surface of the cover.

[0007] As a further improvement, a circuit board is installed on the inner bottom surface of the cover, and a concave battery box is provided on the outer end surface of the cover. In this way, the door lock structure of the safe deposit box can be basically assembled on the cover.

[0008] In order to better constrain the slide plate in the installation cavity of the cover, the slide plate is provided with convex guide ribs arranged in the left and right directions at the upper and lower ends, the bottom surface of the cover is provided with support ribs extending outward, the slide plate is placed on the support ribs, and the bottom surface of the cover is also provided with retaining ribs arranged at intervals up and down, and the retaining ribs are arranged outside the guide ribs. The slide plate is constrained by the rib-groove matching method to ensure that the slide plate can be more stably placed in the cover and can only slide left and right.

[0009] Further improvement, the above-mentioned slide driving structure includes a gear seat, a transmission gear, and a knob. The slide has a left crossbeam, an upper crossbeam, and a lower crossbeam. The upper crossbeam and the lower crossbeam are located on the right side of the left crossbeam and are arranged at intervals. The gear seat is fixed to the inner bottom surface of the cover and is located between the upper crossbeam and the lower crossbeam. The transmission gear is installed on the gear seat and can be selected around its own axis. The driving shaft of the knob is plugged into the transmission gear so that the rotation of the knob can drive the transmission gear to rotate. The upper crossbeam or the lower crossbeam is provided with a rack part meshing with the transmission gear. The transmission gear and the slide form a gear rack transmission mode. The gear rack transmission has the advantage of stable transmission. Importantly, the gear seat is relatively fixed inside the cover and is located between the upper and lower crossbeams. The transmission gear is installed on the gear seat. It can be understood that the entire transmission structure is located inside the slide as a whole. This makes the entire latching structure more compact and suitable for use in small safe deposit boxes.

[0010] As an improvement, the above skateboard further has a right crossbeam, which is connected between the rear ends of the upper crossbeam and the lower crossbeam. The left crossbeam, the right crossbeam, the upper crossbeam and the lower crossbeam form a rectangular frame structure to enhance the overall strength of the skateboard.

[0011] In order to facilitate the quick installation of the transmission gear on the gear seat, the center of the gear seat has a first installation through hole, and the top surface of the transmission gear has at least two first elastic arms extending upward, and the first elastic arms pass through the first installation through hole and then buckle on the top of the gear seat. During installation, the transmission gear can be installed on the gear seat by simply passing the first elastic arm through the first installation through hole and buckling it on the top of the gear seat, ensuring that the transmission gear can rotate around its own axis relative to the gear seat.

[0012] As an improvement, the cross section of the driving shaft of the knob is flat, the top of the driving shaft has two second elastic arms spaced apart, the transmission gear has a second mounting through hole whose shape matches the driving shaft, the driving shaft is inserted into the second mounting through hole and the second elastic arm is buckled on the transmission gear. This structure makes it easy to install the knob on the transmission gear. When installing, just insert it upwards, the second elastic arm will automatically buckle the transmission gear to complete the installation, and the shape of the second mounting through hole in the transmission gear matches the flat hole of the driving rod, so that the rotation of the knob can drive the transmission gear to rotate.

[0013] As a further improvement, a top column with an arc bottom surface is fixed on the gear seat, and a plurality of pits arranged at intervals along the circumference are provided on the upper surface of the transmission gear, and the bottom surface of the top column matches the pits. The bottom surface of the top column matches the pits so that the rotation of the knob has a sense of jerking gear.

[0014] In order to facilitate the slide plate to cooperate with the lock, the slide plate is provided with a raised locking protrusion for forming a blocking match with the lock tongue of the lock. Due to the raised locking protrusion, the lock can be arranged in a front-to-back misaligned manner with the slide plate, and the lock can be arranged behind the slide plate without blocking the slide plate from sliding. The overall layout is more compact and more suitable for small safe deposit boxes.

[0015] As an improvement, the outer end surface of the cover is provided with a plurality of hooks, which enable the cover to have a hanging function, and valuables such as necklaces or keys can be hung on the back of the box door.

[0016] Compared with the prior art, the advantages of the present invention are: changing the conventional design of arranging these components on the door panel, the slide plate, lock and driving structure are all installed on the inner bottom surface of the cover, and a through hole for the bolt head to pass through is opened on the right side wall of the cover, so that the overall door lock structure forms a whole and is no longer installed separately. After the various components are assembled in the cover, it is only necessary to fix the cover to the back of the door of the safe deposit box, and the modular installation of the entire door lock structure is more convenient.

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] See also Figures 1 to 8 Shown is a preferred embodiment of the utility model.

[0027] An integrated door lock structure for a small safe deposit box includes a slide plate 2 with a bolt head 4 at the right end, a lock 9 and a slide plate driving structure, and also includes a cover 1 for fixing on the back of a box door 10. The cover 1 has a mounting cavity Q with an open lower end, and a plurality of hooks 15 are provided on the outer end surface of the cover 1. The slide plate 2 is constrained in the inner bottom surface of the cover 1 and can move left and right. A through hole 13 for the bolt head 4 to pass through is provided on the right side wall of the cover 1. The lock 9 and the driving structure are both installed on the inner bottom surface of the cover 1. The inner bottom surface of the cover 1 has a circuit board 7, and the outer end surface of the cover 1 is provided with a concave battery box 14.

[0028] The upper and lower ends of the slide plate 2 are provided with outwardly protruding guide ribs 22 arranged in the left and right directions. The bottom surface of the cover 1 is provided with outwardly extending support ribs 11. The slide plate 2 is placed on the support ribs 11. The bottom surface of the cover 1 is also provided with retaining ribs 12 arranged at intervals up and down. The retaining ribs 12 are blocked outside the guide ribs 22.

[0029] The skateboard driving structure includes a gear seat 3, a transmission gear 5, and a knob 6. The skateboard 2 has a left crossbeam 2a, an upper crossbeam 2b, a lower crossbeam 2c, and a right crossbeam 2d. The upper crossbeam 2b and the lower crossbeam 2c are located on the right side of the left crossbeam 2a and are arranged at intervals from top to bottom. The right crossbeam 2d is connected between the rear ends of the upper crossbeam 2b and the lower crossbeam 2c. The gear seat 3 fixes the inner bottom surface of the cover and is located between the upper crossbeam 2b and the lower crossbeam 2c. The transmission gear 5 is installed on the gear seat 3 and can be selected around its own axis. The driving shaft 61 of the knob 6 is plugged into the transmission gear 5 so that the rotation of the knob 6 can drive the transmission gear 5 to rotate. The upper crossbeam 2b or the lower crossbeam 2c is provided with a rack portion 21 meshing with the transmission gear 5.

[0030] The center of the gear seat 3 has a first mounting through hole 31, and the top surface of the transmission gear 5 has at least two first elastic arms 51 extending upward, and the first elastic arms 51 pass through the first mounting through hole 31 and are buckled on the top of the gear seat 3. The cross section of the driving shaft 61 of the knob 6 is flat, and the top of the driving shaft 61 has two second elastic arms 62 arranged at intervals. The transmission gear 5 has a second mounting through hole 52 whose shape matches the driving shaft, and the driving shaft 61 passes through the second mounting through hole 52 and the second elastic arm 62 is buckled on the transmission gear 5.

[0031] A top column 8 with an arc bottom is fixed on the gear seat 3 . A plurality of concave pits 53 arranged at intervals along the circumference are provided on the upper surface of the transmission gear 5 . The bottom surface of the top column 8 matches the concave pits 53 .

[0032] The slide plate 2 is provided with a protruding locking protrusion 23 for forming a blocking fit with the locking tongue 91 of the lock 9 .

[0033] The door lock structure changes the conventional design of setting these components on the door panel. The slide plate 2, the lock 9 and the driving structure are all installed on the inner bottom surface of the cover 1. The right side wall of the cover 1 is provided with a through hole 13 for the bolt head 4 to pass through, so that the overall door lock structure forms an integral whole and is no longer installed separately. After the components are assembled in the cover 1, it is only necessary to fix the cover 1 to the back of the door 10 of the safe deposit box. Figure 7 , 8 As shown, the modular installation of the entire door lock structure is more convenient.

[0034] By turning the knob 6, the transmission gear 5 is driven to rotate forward or reversely. Since the rack portion 21 on the upper beam 2b or the lower beam 2c is meshed with the transmission gear 5, the slide plate 2 is driven to slide left and right. The transmission mode of the gear rack has the advantage of smooth transmission. Since the gear seat 3 is fixed in the cover 1 and is located between the upper beam 2b and the lower beam 2c, the transmission gear 5 is installed on the gear seat 3. It can be understood that the entire transmission structure is located inside the slide plate 2 as a whole. This makes the entire latching structure more compact and suitable for use in small safe deposit boxes.
