Description

Lock box with adjusting structure

This creation is about a kind of lock, especially about an electronic lock box.

The electronic lock box refers to a lock with a solenoid valve arranged inside the lock box to unlock by electronic control. In general, in order to ensure that the electronic lock box can work smoothly even when the power is off, the electronic lock box is usually made to have the key unlocking function at the same time. When the power fails, the key can be used to unlock and open the door.

A rotating mechanism is provided inside the conventional electronic lock box, and two handles (representing the inner and outer sides of the door) of the electronic lock box are respectively provided with a handle, each of the handles is connected to the rotating mechanism, and the rotating mechanism is also connected to the The lock tongue is power connected, so that the handle can drive the rotation mechanism to rotate and the lock tongue is displaced and retracted in order to realize the door opening function. In the real environment, for security considerations, at least one side of the electronic lock box needs to be set as the access control surface. Before opening the door from this side, certain verification procedures such as password verification or fingerprint recognition must be passed, and the solenoid valve will only operate after passing. Unlock it. At this time, before the solenoid valve is actuated and unlocked, the handle as the access control surface should not be able to directly and unimpededly drive the rotation mechanism to rotate. An existing method is to jam the handle so that it cannot be turned before unlocking. However, if the handle is damaged by an external force at this time, the internal mechanism of the electronic lock box will be damaged. Therefore, a more ideal approach is to make the handle and the rotating mechanism form an idling state that is not linked. However, because different users and installation environments have different requirements, no matter from the perspective of manufacturing or use, It is best to allow the user to adjust the idling or linkage of the handle and the rotating mechanism on either side according to their needs. Furthermore, the electronic lock box can be divided into fail-safe or fail-secure according to the operating mode of the solenoid valve. The so-called power-off opening refers to the situation in which power is not supplied to the solenoid valve. The electronic lock box is in an unlocked state, and the user can freely open the door; when power is supplied to the solenoid valve, the electronic lock box is in a locked state and the door is locked. The power transmission is just the opposite. The electronic lock box is in the locked state when no power is supplied to the solenoid valve; when the power is supplied to the solenoid valve, the electronic lock box is in the unlocked state. The existing electronic lock box may have the function that allows users to adjust the above two working modes. For example, the patent precedent No. M556764 "Electronic Lock Box" approved by the author, which is capable of adjusting the above two working modes Function.

However, when adjusting the above two working modes in the previous patent, a part of the housing needs to be disassembled to expose the internal parts of the electronic lock box before the mode adjustment screw can be used to switch modes, so it does not have an easy-to-adjustable rotation. The structural design of the linkage between the mechanism and the handles on both sides results in a lack of flexibility in use.

Therefore, how to improve the above-mentioned shortcomings is the technical difficulty that the creators of this case want to solve.

In view of the above, the purpose of this creation is to solve and improve the problems and deficiencies in the traditional use.

In order to achieve the above objectives, the author provides a lock box with an adjustment structure, which includes: a housing, a bolt mechanism, a rotation mechanism, and a mode switching mechanism. The bolt mechanism is provided in the housing; the rotation mechanism is provided in the housing, and the rotation mechanism is power connected with the bolt mechanism; and the mode switching mechanism is provided in the housing, and the mode switching mechanism includes It includes a linear actuator with adjustable position, a driven mechanism, a cam mechanism and a clamping mechanism, the driven mechanism is respectively power connected with the linear actuator and the cam mechanism, and the clamping mechanism is arranged in Between the cam mechanism and the rotating mechanism, the mode is switched by adjusting the position of the linear actuator.

Preferably, the linear actuator is fixed on a positioning seat, and the positioning seat is provided with a first positioning hole, a second positioning hole, and a third positioning hole at intervals.

Preferably, the first positioning hole is locked by a first positioning member, and the second positioning hole or the third positioning hole is locked by a second positioning member.

Please refer to FIG. 3 in conjunction. Specifically, the positioning seat 45 is provided with a first positioning hole 451, a second positioning hole 452, and a third positioning hole 453 at intervals. The first positioning hole 451 and the second positioning hole 452 are spaced apart. Both the third positioning hole 453 can be a screw hole. The first positioning hole 451 corresponds to the movable hole 11 of the housing 1, and the second positioning hole 452 (or the third positioning hole 453) corresponds to the fixing hole 12 of the housing 1. In this way, the first positioning member 13 penetrates the movable hole 11 of the housing 1 and is locked to the first positioning hole 451 of the positioning base 45, and the positioning base 45 can be moved by moving the first positioning member 13 Sliding along the first direction X; the second positioning member 14 penetrates the fixing hole 12 of the housing 1 and is locked to the second positioning hole 452 (or the third positioning hole 453) of the positioning seat 45, so that The positioning base 45 is locked on the housing 1 and cannot be slid.

The driven mechanism 42 is respectively power connected with the linear actuator 41 and the cam mechanism 43. The clamping mechanism 44 is arranged between the cam mechanism 43 and the rotating mechanism 3, and the clamping mechanism 44 can extend into the rotating mechanism 3. In a groove 32 of the rotation mechanism, the cam mechanism 43 and the rotation mechanism 3 are in a linked unlocked state; or the locking mechanism 44 can be far away from the groove 32 of the rotation mechanism 3, so that the cam mechanism 43 and the rotation mechanism 3 are in an idling state that does not interlock with each other. In addition, the linear actuator 41 can drive the driven mechanism 42 to move linearly along the first direction X, the driven mechanism 42 can drive the cam mechanism 43 to move linearly along the second direction Y, and the cam mechanism 43 can drive the clamping mechanism. The mechanism 44 moves linearly in the second direction Y.

The driven mechanism 42 has a bottom 421 and a top 422, and the top 422 and the bottom 421 are parallel. The bottom 421 of the driven mechanism 42 is respectively provided with a first guide hole 423 and a second guide hole 424 along the first direction X.

The cam mechanism 43 is also provided with an inverted V-shaped groove 433. The V-shaped groove 433 is provided with a first straight section 434 inclined from upper left to lower right and a second straight section 435 inclined from upper right to lower left, and the first straight line The section 434 is connected with the second straight section 435.

The mode switching mechanism 4 also includes a second guide post 46, a third guide post 47, a fourth guide post 48 and a fifth guide post 49. The second guide post 46 penetrates through the second guide hole 424 of the driven mechanism 42 and is fixed to the housing 1, for example by screw connection; the third guide post 47 penetrates through the second guide hole 424 of the cam mechanism 43 The three guide holes 431 are fixed to the housing 1; the fourth guide post 48 penetrates the fourth guide hole 432 of the cam mechanism 43 and is fixed to the housing 1; the fifth guide post 49 penetrates The coupling hole 425 of the driven mechanism 42 and the V-shaped groove 433 of the cam mechanism 43 are provided so that the fifth guide post 49 can slide in the V-shaped groove 433, so that each guide post can provide The effect of guiding the driven mechanism 42 or the cam mechanism 43 to stably move linearly in the first direction X or the second direction Y.

The following explains the working principle of the creation of mode switching to switch the electronic lock box to the power-off or power-on mode of operation: please refer to Figure 4 and Figure 5, and cooperate with Figure 3, in this When the linear actuator 41 is not energized (ie, powered off), if the user wants to set the electronic lock box to the power-on operation mode, firstly take out the second positioning hole 452 and the fixing hole 12 The second positioning member 14 moves the first positioning member 13 so that the positioning seat 45 slides along the first direction X, and then the second positioning member 14 is locked into the fixing hole 12 and the third positioning seat. Positioning hole 453. At this time, the operation mode will be switched to power transmission ON. In this way, the spring 411 of the linear actuator 41 drives the driven mechanism 42 to move away from the linear actuator 41, because the fifth guide post 49 is to pass through the coupling hole 425 of the driven mechanism 42 and the V-shaped groove 433 of the cam mechanism 43, and the inclination directions of the first straight section 434 and the second straight section 435 of the V-shaped groove 433 are opposite. The five guide post 49 moves from the first straight section 434 of the V-shaped groove 433 to the second straight section 435, so the driven mechanism 42 and the fifth guide post 49 can use the cam principle to drive the cam mechanism 43 away from the rotation mechanism 3. When the locking mechanism 44 moves away from the groove 32 of the rotation mechanism 3, the cam mechanism 43 and the rotation mechanism 3 are in a non-interlocking idling state, so the door cannot be opened and is in a locked state. When the linear actuator 41 is energized, the linear actuator 41 can drive the driven mechanism 42 to move closer to the linear actuator 41, because the fifth guide post 49 penetrates the driven mechanism 42 The coupling hole 425 and the V-shaped groove 433 of the cam mechanism 43, the fifth guide post 49 moves from the first straight section 434 of the V-shaped groove 433 into the second straight section 435, the driven mechanism 42 and the fifth guide post 49 The cam mechanism can be used to drive the cam mechanism 43 and the clamping mechanism 44 to move closer to the rotation mechanism 3. The clamping mechanism 44 extends into the groove 32 of the rotation mechanism 3, so that the cam mechanism 43 and the rotation mechanism The rotating mechanism 3 is in a linked unlocked state, so that it meets the functional requirements of the power transmission on mode.

Please refer to Figures 6 and 7, and in conjunction with Figure 3, if the user wants to set the lock to the power-off operation mode, the second positioning hole 452 and the fixing hole 12 can be taken out first. 14, and then move the first positioning member 13 to make the positioning seat 45 slide along the first direction X, which Then lock the second positioning member 14 into the fixing hole 12 and the second positioning hole 452 of the positioning seat. At this time, the operation mode will be switched to power-off, and the spring 411 of the linear actuator 41 drives the slave The moving mechanism 42 moves away from the linear actuator 41, because the fifth guide post 49 penetrates the coupling hole 425 of the driven mechanism 42 and the V-shaped groove 433 of the cam mechanism 43, and the V-shaped groove The inclination directions of the first straight section 434 and the second straight section 435 of 433 are opposite, the fifth guide post 49 moves into the second straight section 435 of the V-shaped groove 433, so the driven mechanism 42 and the fifth guide post 49 The cam mechanism can be used to drive the cam mechanism 43 to move closer to the rotation mechanism 3. The locking mechanism 44 extends into the groove 32 of the rotation mechanism 3, so that the cam mechanism 43 and the rotation mechanism 3 become linked Unlock (unlock) state. When the linear actuator 41 is energized, the linear actuator 41 can drive the driven mechanism 42 to move closer to the linear actuator 41, because the fifth guide post 49 penetrates the driven mechanism 42 The coupling hole 425 and the V-shaped groove 433 of the cam mechanism 43, the fifth guide post 49 moves into the second straight section 435 of the V-shaped groove 433, the driven mechanism 42 and the fifth guide post 49 can be driven by the principle of cam The cam mechanism 43 is displaced in a direction away from the rotation mechanism 3, and the locking mechanism 44 leaves the groove 32 of the rotation mechanism 3, so that the cam mechanism 43 and the rotation mechanism 3 are in a non-linked idling state, so the door cannot be opened. It is in a locked state, so that it meets the functional requirements of the power-off mode.

In this way, the present invention allows users to easily adjust the linkage state of the rotating mechanism, and work modes such as power-off or power-on without disassembling the casing, greatly improving the flexibility and efficiency of use.
