DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] The purpose of the present invention is to provide a double-locking password storage box lock to solve the problems existing in the above-mentioned prior art. It can lock small personal belongings in the storage box and can also lock the storage box itself to a fixed position such as a tree, a railing, a pillar, etc.

[0040] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] In order to temporarily store small portable items and lock the storage box for storing these items, this embodiment provides a double-locking password storage box lock, such as Figure 1 to Figure 12 As shown, it includes a lower shell 23, a top cover 24, a password part, a gate lock and a steel cable assembly 2, a storage cavity is formed in the lower shell 23, and a spring tongue lock hole 14 is opened on the upper side wall of the lower shell 23; a rotatable locking device is provided at the bottom of the top cover 24, and a spring tongue 12 is connected to the locking device; the top cover 24 can be rotatably connected to the top side wall of the lower shell 23, and when rotated to a set position, the end of the spring tongue 12 can be inserted into the spring tongue lock hole 14 to achieve the first level of locking.

[0042] The password part of this embodiment is arranged on the top cover 24, which includes a password wheel 6 component and a hand wheel. When the password wheel 6 component is turned to the set sequence, the hand wheel can drive the locking device to rotate and drive the spring tongue 12 to retreat to disengage from the spring tongue lock hole 14; the gate lock is arranged in the connecting ears 21 on both sides of the outside of the top cover 24, and includes a steel cable gate 26 and a steel cable gate button 25. The steel cable gate button 25 is movably inserted into the bottom through hole of the connecting ear 21; the two ends of the steel cable assembly 2 can be respectively inserted into the gate lock from the top through holes of the two connecting ears 21, and the steel cable gate button 25 rises to the inside of the connecting ear 21. When the lower shell 23 and the top cover 24 are first locked, the bottom of the connecting ear 21 abuts against the top of the limiting ear 22 on the same side, and the cable gate button 25 is lifted to the inside of the connecting ear 21, and the second locking is achieved through the gate lock and the cable assembly 2. When unlocking, it is necessary to first contact the first lock, and then rotate the top cover 24 in the opposite direction so that the connecting ear 21 and the limiting ear 22 are no longer docked, and then the second locking can be started.

[0043] In one embodiment, in order to realize the locking function of the steel cable assembly 2, in this embodiment, the lower part of the steel cable brake button 25 is a columnar structure, which can be inserted into the bottom through hole of the connecting ear 21, and a U-shaped groove 2501 is provided on the top of the steel cable brake button 25, and a positioning groove 2502 is provided on the side walls of the openings on both sides of the U-shaped groove 2501, and a steel cable brake 26 is provided on the outer side of the openings on both sides of the U-shaped groove 2501, and the end of the steel cable brake 26 away from the steel cable brake button 25 is connected to a first elastic member, and the first elastic member of this embodiment is a first spring 27. The steel cable assembly 2 includes a steel cable body 201 and a steel cable plug 202, and the steel cable body 201 is fixed with a steel cable plug 202 at both ends. The end of the steel cable plug 202 is a smooth arc structure, and the side wall of the steel cable plug 202 is provided with an annular groove 2 03. The arc surface structure at the end of the steel cable plug 202 extends to the bottom of the annular groove 203, so that when the steel cable plug 202 is inserted into the U-shaped groove 2501 of the steel cable gate button 25, the steel cable gates 26 on both sides can be buckled in the annular groove 203 to lock the steel cable plug 202. The top of the annular groove 203 is a horizontal top wall structure. Therefore, after the steel cable plug 202 is locked by the steel cable gate 26, it cannot pass out from the other end. When the bottom of the steel cable gate button 25 goes up to the inside of the connecting ear 21, the positioning groove 2502 is at the same height as the steel cable gate 26. Under the elastic force of the first spring 27, the steel cable gate 26 can be driven horizontally into the positioning groove 2502. An inwardly concave arc groove is provided at the end of the steel cable gate 26, and the arc groove can contact and connect with the side wall of the annular groove 203 of the steel cable plug 202 to achieve locking. At this time, if the steel cable plug 202 is located in the U-shaped groove 2501 of the steel cable brake button 25, its annular groove 203 is locked by the steel cable brake 26. If the steel cable plug 202 is not located in the U-shaped groove 2501, since the first spring 27 drives the steel cable brake 26 to move horizontally inward to the positioning groove 2502, the space between the two steel cable brakes 26 becomes smaller. When the steel cable plug 202 is inserted into the through hole at the top of the connecting ear 21, the smooth arc surface structure at the bottom of the steel cable plug 202 can squeeze the two steel cable brakes 26 open. The two wire rope gates 26 squeeze the first spring 27 and retreat, and the wire rope plug 202 continues to move downward into the space between the two wire rope gates 26 until the wire rope gate 26 is at the same height as the annular groove 203 of the wire rope plug 202. The wire rope gate 26 is engaged in the annular groove 203 under the restoring force of the first spring 27. The fixed wall and the bottom wall of the annular groove 203 are both horizontal structures. Therefore, no matter the wire rope plug 202 is pulled outward or pushed inward, it cannot be moved due to the limiting effect of the two wire rope gates 26 in the annular groove 203, so the wire rope plug 202 is locked.

[0044] In order to unlock the cable plug 202, a first inclined surface 2601 is provided on the upper part of the cable brake 26 away from the first spring 27 in this embodiment, and a second inclined surface 2503 with the same inclined direction as the first inclined surface 2601 is provided on the upper side wall of the positioning groove 2502 of the cable brake button 25. When the cable brake 26 is engaged with the annular groove 203 under the restoring force of the first spring 27, the first inclined surface 2601 and the second inclined surface 2503 are in contact and connected; when there is no limit at the bottom of the connecting ear 21, the cable assembly 2 is pushed downward from the outside, so that the cable plug 202 is brought into contact with the cable assembly 2. The cable brake button 25 is moved downward synchronously. During the process, the second inclined surface 2503 of the upper side wall of the positioning groove 2502 of the cable brake button 25 squeezes the first inclined surface 2601 above the end of the cable brake 26 to move relatively. During the process, the cable brake 26 squeezes the first spring 27 to retreat. When the bottom of the cable brake button 25 extends out from the bottom through hole of the connecting ear 21, the cable brake 26 is squeezed to disengage from the positioning groove 2502, and the end of the cable brake 26 is limited to the outer side wall of the upper part of the cable brake button 25. At this time, the end of the cable brake 26 is out of the annular groove 203, and the lock on the cable plug 202 is released. , the cable plug 202 can be pulled out from the connecting ear 21 to achieve unlocking; when the top cover 24 is fixedly connected to the lower shell 23 and once locked, the bottom of the connecting ear 21 of the top cover 24 abuts against the top of the limiting ear 22 of the lower shell 23. At this time, the through hole at the bottom of the connecting ear 21 is sealed, and the bottom of the cable brake button 25 is squeezed into the connecting ear 21 and cannot be extended. Therefore, the first inclined surface 2601 and the second inclined surface 2503 cannot move up and down relative to each other. Therefore, at this time, the cable brake 26 moves horizontally to the positioning groove 2502 of the same height under the elastic force of the first spring 27, locking the cable plug 202. The annular groove 203 is engaged with the steel cable plug 202, thereby locking the steel cable plug 202. Under the elastic force of the first spring 27, no matter whether the steel cable plug 202 is pulled outward or pushed inward, the end of the steel cable gate 26 cannot be separated from the annular groove 203, and the steel cable plug 202 is firmly locked. Before inserting the steel cable plug 202, the steel cable body 201 is wrapped around a tree trunk, a railing, etc., and then the two steel cable plugs 202 are respectively inserted into the corresponding connecting ears 21 to achieve locking. Then, the storage box can be locked as a whole at a tree trunk, a railing, etc. to prevent theft.

[0045] In order to make the overall operation of the gate lock smoother and the connection more stable, a steel cable gate bracket 28 is designed in this embodiment. A bracket connecting plate 2801 extending outward is provided at the bottom of the steel cable gate bracket 28. The bracket connecting plate 2801 is fixedly connected to the bottom of the connecting ear 21 by screws. A bracket cavity that passes through from top to bottom is opened in the steel cable gate bracket 28, and openings are provided on both sides of the bracket cavity. The openings are larger than the cavities on both sides of the U-shaped groove 2501 of the steel cable gate button 25. The steel cable gate 26 is located at the openings on both sides of the bracket cavity, so that the steel cable gate 26 can freely enter and exit through the openings; the steel cable gate button 25 is movably arranged in the bracket cavity, and a first limiting protrusion 2802 is provided on the inner wall of the through hole at the bottom of the bracket cavity. The lower side of the U-shaped groove 2501 of the steel cable gate button 25 A second limiting protrusion 2504 is provided on the wall. When the bottom of the cable gate button 25 extends out of the bottom through hole of the connecting ear 21, the first limiting protrusion 2802 and the second limiting protrusion 2504 abut against each other, which can limit the cable gate button 25 and prevent it from completely detaching from the connecting ear 21 from the bottom of the connecting ear 21; a stopper 13 is provided on the bracket connecting plate 2801, and a slot is formed between the stopper 13 and the side wall of the cable bracket with an opening, and a spring top sheet 29 is fixedly inserted in the slot, one end of the first spring 27 is connected to the spring top sheet 29, and the other end is connected to the cable gate 26, so that the first spring 27 and the spring top sheet 29 can provide horizontal elastic force for the cable gate 26, and can push the cable gate 26 to move horizontally to the positioning groove 2502 of the cable gate button 25.

[0046] In order to achieve a single lock of the lower shell 23 and the top cover 24, a cover 16 is fixedly provided at the bottom of the top cover 24 in this embodiment, a locking device and a spring tongue 12 are provided between the top cover 24 and the cover 16, a cover 16 hole is provided on the side wall of the cover 16, and the end of the spring tongue 12 can pass through the cover 16 hole and be inserted into the spring tongue lock hole 14; the locking device of this embodiment includes a spring tongue turntable 11 fixedly connected to the hand wheel, an arc-shaped track hole 1101 is opened on the spring tongue turntable 11, a spring tongue bracket 1 is slidably connected in the arc-shaped track hole 1101, and the spring tongue bracket 1 is provided with a spring tongue at one end away from the arc-shaped track hole 1101. The spring tongue 12 cavity is movably arranged in the spring tongue 12 cavity, and one end of the spring tongue 12 is connected to the bottom of the spring tongue 12 cavity by a second elastic member, and the second elastic member is a second spring 15. When the top cover 24 is connected to the lower shell 23, when the top cover 24 just starts to rotate on the upper part of the lower shell 23, the end of the spring tongue 12 is pressed tightly by the side wall of the lower shell 23, and the spring tongue 12 retreats from the cover 16 hole to squeeze the second spring 15. At this time, the spring tongue 12 retracts into the spring tongue 12 cavity. When the top cover 24 rotates to the bottom, the cover 16 hole and the spring tongue lock hole 14 of the lower shell 23 are coaxial. At this time, under the elastic force of the second spring 15 The spring tongue 12 moves outward, passes through the cover 16 hole, and is inserted into the spring tongue lock hole 14 to achieve a single lock of the lower shell 23 and the top cover 24. The top cover 24 is provided with two symmetrical spring tongue 12 structures and a spring tongue bracket 1 structure. Similarly, the lower shell 23 is also provided with two spring tongue lock holes 14, so that the two spring tongues 12 can be inserted into the corresponding spring tongue lock holes 14 at the same time, so that the locking effect is better; the hand wheel of this embodiment can drive the spring tongue turntable 11 to rotate. When the password wheel 6 assembly rotates to the set position, the hand wheel drives the spring tongue turntable 11 to rotate. Since the spring tongue turntable 11 is provided with a smooth The arc-shaped track hole 1101, so the tongue bracket 1 movably connected with the arc-shaped track hole 1101 of the tongue turntable 11 moves along the arc-shaped track hole 1101 when the tongue turntable 11 rotates. Since the tongue bracket 1 is radially limited by the cover 16, its relative movement with the arc-shaped track hole 1101 at this time is axial movement, and then the tongue bracket 1 moves axially back and forth synchronously, which can drive the tongue 12 to retreat to disengage from the tongue lock hole 14. At this time, the lower shell 23 and the top cover 24 are unlocked, and the top cover 24 can be twisted in the reverse direction to open the top cover 24 and the lower shell 23, so as to facilitate taking out the items in the storage cavity.

[0047] In order to achieve a single-locking effect, the handwheel of this embodiment includes a handwheel shell 9, a handwheel holder 8 and a handwheel password frame 10.
