Description

Technical Field

[0001] The invention relates to the technical field of password lock elements, in particular to a drop-resistant and shock-proof password lock. Background Art

[0002] A combination lock is a type of lock that uses a series of numbers or symbols to open. Some combination locks only use a dial, while others turn a set of dial rings engraved with numbers to directly drive the mechanism inside the lock.

[0003] Combination locks are extremely common in life and most people have used them. The operating mode of their internal machinery is now mature and the operating principle is widely known. Traditional combination locks are easily affected by the external environment due to their wide range of usage scenarios. For example, when transporting objects, when the locked object overturns, it is easy to cause bumps to the combination lock and damage to the corners. At this time, it can only be replaced. Currently, there is a product that attaches an anti-fall pad to the combination lock to protect the corners of the combination lock from damage, which solves this problem. However, based on daily life experience, due to the wide range of usage scenarios and strong applicability of combination locks, they are more affected by the use environment. In addition to the direct overturning of the locked object, there are still factors that affect the long-term use of the combination lock under natural use conditions. Ordinary combination lock devices have weak response functions to the influence of external factors in daily life, the overall practicality of the components is not strong, and the actual long-term use experience needs to be improved.

[0026] At the same time, the structure is set to make the pressure sealing effect of the rubber ring adaptable, that is, the sealing firmness of the connection opening between the lock body and the lock rod can be achieved for locked parts of different thicknesses, achieving the preset sealing effect. In general, the adaptability of the component is stronger;

[0027] And through the arrangement of locking plate one and locking plate two, when maintaining the pressing state on the rubber ring, locking plate two maintains a fit state with the parallel edge of the incomplete gear, that is, locking plate two can provide additional protection for maintaining the pressing state of the rubber ring, and it is not easy to separate from the rubber ring by itself due to structural damage.

[0028] 3. The present invention makes the device self-locking in actual operation through the arrangement of the ratchet groove, the locking rod and the main shaft. The overall operation is simple and meets the practical requirements of small-volume components. It can be operated with one hand during use. The driving and unlocking methods are both on the side, which also reduces the width of the component accordingly and allows it to be used for a longer time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] 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.

[0041] For example, see Figures 1 to 10 The present invention provides a drop-resistant and shock-proof password lock, comprising a lock body 1 and a lock rod 2. The corners of the lock body 1 are covered with drop-resistant pads 3, and the rod wall of the lock rod 2 is sleeved with a limit plate 4.

[0042] See also Figure 1 The thickness of the anti-fall pad 3 is adapted to the size of the lock body 1, and the surface of the anti-fall pad 3 is provided with anti-slip patterns. By limiting the material and size of the anti-fall pad 3, the overall volume of the component is prevented from being too large, which affects the actual padlock effect.

[0043] See also Figure 2 The inner wall of the lock body 1 is embedded with an anti-rust component, which is specifically a gas phase anti-rust rod 36. The gas phase anti-rust rod 36 volatilizes the anti-rust gas to form a protective layer inside the lock body 1, thereby preventing the internal components from rusting and preventing the combination lock from being unusable due to corrosion.

[0044] Adaptive components are provided on both sides of the lock body 1. A rubber ring 5 is embedded in the lock body 1. The lock rod 2 passes through the rubber ring 5. Sealing components are provided on both sides of the rubber ring 5. The sealing components include an extrusion ring 6.

[0045] The adapting component comprises an extruding component and two groups of transmission components, both of which are in transmission connection with the extruding component, and the adapting component further comprises a self-locking component and a driving component.

[0046] In this embodiment, when in use, the locked object is locked by the cooperation between the lock body 1 and the lock rod 2. The working principles of the lock body 1 and the lock rod 2 and the password unlocking principle are mature in the prior art and will not be repeated here. The anti-fall pad 3 is provided to prevent the password lock device from being damaged by collision with the overturning of the locked object. After the person locks the object, the driving component and the self-locking component can be synchronously cooperated to drive the extrusion component to operate, so that the limit plate 4 is displaced along the rod diameter direction of the lock rod 2, thereby reducing the gap between the lock body 1 and the lock rod 2, so that the lock body 1 is firmly fixed on the locked object, avoiding the lock body 1 from colliding and shaking during the transportation of the object, and thus making it difficult to bump during use, thereby ensuring the long-term practicality of the lock body 1;

[0047] At the same time, the two groups of transmission parts operate synchronously, and the two extrusion rings 6 are displaced synchronously to squeeze the rubber ring 5, so that the rubber ring 5 is tightly attached to the lock rod 2, so that the connection opening between the lock rod 2 and the lock body 1 is closed, avoiding the influence of external factors such as rain during use, causing water to flow from the lock rod 2 into the lock body 1, ensuring the long-term use of the lock body 1 and avoiding rust inside the lock body 1.

[0048] See also Figures 1 to 6 , Fig.10 The extrusion component includes a body 7, which is fixedly connected to the surface of the lock body 1. The inner wall of the body 7 is rotatably connected to a main shaft 8, and the shaft wall of the main shaft 8 is fixedly connected to a gear 9. The inner wall of the body 7 is fixedly connected to a limit rod 10, and the rod wall of the limit rod 10 is slidably connected to a rack row 11. The teeth of the rack row 11 are meshed with the teeth of the gear 9. The lower end of the rack row 11 is fixedly connected to a plate 12, and an opening 1 is provided on the surface of the plate 12 for the limit rod 10 to pass through. The bottom surface of the plate 12 is fixedly connected to two rods 13, and the two rods The inner wall of component 13 is fixedly connected with an adaptable spring 14, the inner walls of the two rod components 13 are slidably connected with rod component 2 15, the rod walls of the two rod components 2 15 are slidably connected with plate component 2 16, plate component 2 16 is fixedly connected to the inner wall of the main body 7, the rod walls of the two rod components 2 15 are slidably connected to the inner wall of the main body 7, the surface of plate component 2 16 is fixedly connected to the lower end of the limit rod 10, the plate component 2 16 and the opposite side of the plate component 1 12 are jointly fixedly connected with a reset spring 17, and the ends of the two rod components 2 15 are fixedly connected to the surface of the limit plate 4.

[0049] In this embodiment, by rotating the main shaft 8, the gear 9 is rotated, so that the rack row 11 moves vertically downward along the rod wall of the limit rod 10, and the vertical downward movement of the rack row 11 can synchronously drive the plate 12 to move downward synchronously, thereby driving the two rods 13 to move downward synchronously, and then through the transmission of the two adaptive springs 14, the two rods 2 15 are synchronously moved vertically downward, and then the limit plate 4 is pushed to move vertically downward, so as to press the connecting piece of the locked object until the connecting piece of the locked object is close to the inner wall of the lock body 1. At this time, the lock body 1 and the locked object remain firmly, so that the lock body 1 will not shake when the locked object is moved. This can make the device not easy to bump during use, and its practicality is improved.

[0050] It is worth noting that when the lock body 1 and the locked object are firmly connected, the state of the limit plate 4 is kept unchanged by the self-locking component, and in this state, the return spring 17 remains compressed.

[0051] See also Figures 3 to 7 The transmission component includes a shaft body 18, an incomplete gear 19 is fixedly connected to the shaft wall of the shaft body 18, the end of the shaft body 18 is rotatably connected to the inner wall of the main body 7, two hinged rods 20 are fixedly connected to the shaft wall of the shaft body 18, and the ends of the two hinged rods 20 are hingedly connected to a hinged rod 21, and the rod wall of the hinged rod 21 is provided with a notch matched with the shaft body 18, a piston rod 22 is hingedly connected to the end of the hinged rod 21, and a piston cylinder assembly 23 is fixedly connected to the end of the piston rod 22, a short shaft group 24 is fixedly connected to the side wall of the rack row 11, and a locking plate 25 and a locking plate 26 are fixedly connected to the side wall of the rack row 11.

[0052] In this embodiment, during the vertical downward movement of the rack row 11, the short shaft group 24, the locking plate 1 25 and the locking plate 2 26 will also be driven to move downward synchronously. At this time, the locking plate 1 25 will first be disengaged from the parallel side of the incomplete gear 19. At this time, as the short shaft group 24 continues to move downward, it will cooperate with the teeth of the incomplete gear 19, and will push the incomplete gear 19 to rotate until the short shaft group 24 is disengaged from the teeth of the incomplete gear 19. At this time, the parallel side of the incomplete gear 19 is in contact with the surface of the locking plate 2 26. In this way, during the vertical downward movement of the rack row 11, the incomplete gear 19 can be deflected 180°, thereby driving the shaft body 18 to deflect, and then through the transmission of the two hinged rods 1 20, the hinged rod 21 is operated, and then the piston rod 22 is pushed to displace along the inner wall of the piston cylinder assembly 23.

[0053] It is worth noting that, since the wall of the second hinge rod 21 is provided with a notch matched with the shaft body 18 and the width of the wall of the second hinge rod 21 is larger than the cross-sectional diameter of the shaft body 18 , the second hinge rod 21 does not affect the deflection of the shaft body 18 .

[0054] See also Figures 3 to 7 The sealing component includes a delivery pipe 27, which is buried in the inner wall of the lock body 1. Both piston cylinder assemblies 23 are fixedly connected to the delivery pipe 27. The surface of the extrusion ring 6 is fixedly connected with a push rod group 28, which is slidably connected to the inner wall of the delivery pipe 27. The delivery pipe 27 is filled with hydraulic oil 29.

[0055] In this embodiment, during the operation of the above-mentioned piston rod 22, the hydraulic oil 29 can be pushed. Through the transmission of the hydraulic oil 29, the push rod group 28 can be displaced, and then the extrusion ring 6 can be displaced in the direction of the rubber ring 5. In this way, the rubber ring 5 can be squeezed, and the connection opening between the locking rod 2 and the lock body 1 can be closed, avoiding the influence of external factors such as rain during use, causing water to flow from the locking rod 2 into the lock body 1, thereby ensuring the long-term use of the lock body 1 and avoiding rust inside the lock body 1.

[0056] It is worth noting that, by adopting the above-mentioned method, when the thickness of the locked object is different, the limit plate 4 will not be too close to the inner wall of the lock body 1. During this process, since the internal structure of the body 7 is still in operation, the two adaptation springs 14 can be gradually compressed to adapt to this stage. That is, during this process, the rack row 11 can continue to move downward until its parallel edge fits the surface of the second locking plate 26, thereby completing the pressing of the rubber ring 5.

[0057] From the above, it can be seen that through the setting of the structure, on the one hand, the pressure effect on the locked object will not fail as the thickness increases, but the pressure strength will increase accordingly. At the same time, the pressure seal of the rubber ring 5 is adaptable, that is, the sealing firmness of the connecting opening between the lock body 1 and the locking rod 2 can be achieved for locked parts of different thicknesses, and the preset sealing effect can be achieved. Generally speaking, the adaptability of the components is stronger and the practicality is further improved.

[0058] Embodiment 2, based on the above embodiment:

[0059] See also Figures 3 to 8 The self-locking component includes a main shaft 30, which is spline-type slidably connected to the inner wall of the main shaft 8. Both sides of the body 7 are provided with openings 2 and 3 for the two ends of the main shaft 30 to pass through respectively. The shaft arm of the main shaft 30 is fixedly connected with a self-locking spring 31, and the end of the self-locking spring 31 is fixedly connected with a locking rod 32. The end of the locking rod 32 is rotatably connected to the shaft arm of the main shaft 30. A ratchet groove 33 is provided on the inner wall of the opening 2, and the end of the locking rod 32 is in contact with the groove wall of the ratchet groove 33.

[0060] In this embodiment, the main shaft 2 30 can be rotated and the main shaft 8 can be driven to rotate through the spline sliding connection between the main shaft 2 30 and the main shaft 1 8. During the rotation of the main shaft 2 30, the locking rod 32 is synchronously driven to move. At this time, during the downward movement of the rack row 11, the ratchet groove 33 will not block the locking rod 32. At this time, the self-locking spring 31 is deformed. When the limit plate 4 completes the restriction on the locked object, the locking rod 32 can be restricted by the ratchet groove 33, so that the main shaft 2 30 cannot rotate reversely, thereby maintaining the state of the limit plate 4.

[0061] See also Fig. 9 The driving component includes a twisting wheel 34, which is spline-slidably connected to the shaft arm of the main shaft 30, and the end of the twisting wheel 34 is rotationally connected to the surface of the main body 7. The end of the main shaft 30 is fixedly connected to a driving spring 35, and the end of the driving spring 35 is fixedly connected to the inner wall of the twisting wheel 34.

[0062] In this embodiment, the second spindle 30 can be driven to rotate by rotating the knob 34 through the spline sliding connection between the knob 34 and the second spindle 30. When unlocking is required, the second spindle 30 exposed on the other side of the body 7 can be pressed, so that the locking rod 32 is displaced and interlaced with the ratchet groove 33. At this time, the knob can be rotated in the reverse direction.

[0063] After the reset is completed, the pressing finger is directly released to quickly reset through the driving spring 35.

[0064] In summary, through the structural setting, the device can be self-locking in actual operation, the overall operation is simple, and it meets the practical requirements of small-volume components. It can be operated with one hand during use. The driving and unlocking methods are on the side, which also reduces the width of the component accordingly.

[0065] Working principle: When the drop-resistant and shock-proof password lock is in use, the locked object can be locked through the cooperation between the lock body 1 and the locking rod 2. The drop-resistant pad 3 can prevent the password lock device from being damaged by collision as the locked object overturns. After the person locks the object, the knob 34 can be rotated synchronously to make the limit plate 4 displace along the rod diameter direction of the locking rod 2, thereby reducing the gap between the lock body 1 and the locking rod 2, so that the lock body 1 is firmly fixed on the locked object, avoiding the lock body 1 from colliding and shaking during transportation, and thus making it less likely to be bumped during use, thereby ensuring the long-term practicality of the lock body 1. At the same time, the two extrusion rings 6 are displaced synchronously to squeeze the rubber ring 5, so that the rubber ring 5 is close to the locking rod 2, so that the connection opening between the locking rod 2 and the lock body 1 is closed, avoiding the influence of external factors such as rain during use, causing water to flow from the locking rod 2 into the lock body 1, ensuring the long-term usability of the lock body 1, and avoiding rust inside the lock body 1.

[0066] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
