[0030] Unless specifically stated or defined otherwise, the "first, second" used herein is merely used for the differentiation of names, and does not represent the specific quantity or order.
[0031] Unless specifically stated or defined otherwise, the term "and / or" used herein includes any and all combinations of one or more related listed items.
[0032] It should be noted that "fixed to", "connected to" in this paper can be directly fixed or connected to an element, or indirectly fixed or connected to an element.
[0033] The utility model embodiment provides a key locking device 100, such as Figures 1 to 7 As shown, the key locking device 100 includes: seat body 1, key column 2 and locking assembly 3.
[0034] The seat body 1 is provided with a slot 11, and the side wall of the seat body 1 is provided with a locking hole 12 in communication with the slot 11;The key column 2 is provided with a locking groove 21, and the key column 2 is detachably inserted into the slot 11 of the seat body 1;Wherein, the key column 2 is used for hanging mechanical key, the seat body 1 is the main part of the key locking device 100, the seat body 1 is provided with a slot 11 with one end opening, so that the key column 2 can be inserted into the slot 11 to be connected to the seat body 1, when the key column 2 is inserted into the slot 11 to the position, the locking groove 21 of the key column 2 is aligned with the locking hole 12, at this time, the locking assembly 3 can be locked to the key column 2 through the locking hole 12 and the locking groove 21.
[0035] The locking assembly 3 comprises a locking piece 31 and a driving device 32 which is independently arranged from the locking piece 31; the locking piece 31 is elastically arranged on the seat body 1 and slides along the locking hole 12 to be inserted into or separated from the locking groove 21; wherein the elasticity of the locking piece 31 helps it to keep good contact with the locking groove 21 when it is subjected to external force, and also facilitates its separation from the locking groove 21 in the unlocked state. The driving device 32 is movably arranged on the seat body 1 and acts on the locking piece 31 when it is in the first position or the second position; when the driving device 32 is in the first position, the locking piece 31 is inserted into the locking groove 21 to limit the key post 2 from separating from the insertion slot 11; when the driving device 32 is in the second position, the locking piece 31 is separated from the locking groove 21. Wherein the driving device 32 controls the movement of the locking piece 31 by acting on the locking piece 31 in the first position or the second position, and the driving device 32 can be designed in various forms as long as it can form a force acting on the locking piece 31, which is not particularly limited here. Since the driving device 32 can act on the locking piece 31 in the first position or the second position, the driving device 32 can limit the movement of the locking piece 31 to form a locked state or drive the locking piece 31 to move to form an unlocked state. Specifically, when the driving device 32 acts on the locking piece 31 in the first position, the locking piece 31 is inserted into the locking groove 21 to limit the key post 2 from separating from the insertion slot 11, and the driving device 32 prevents the locking piece 31 from separating from the locking groove 21 by its force, thereby locking the key post 2 to the seat body 1; when the driving device 32 moves to the second position, the driving device 32 is independently arranged relative to the locking piece 31, the force of the driving device 32 on the locking piece 31 disappears, and the locking piece 31 can be separated from the locking groove 21 under the action of external force, so that the key post 2 is unlocked from the seat body 1, and the key post 2 can be taken to the unlocking device for unlocking operation. Alternatively, when the driving device 32 acts on the locking piece 31 in the second position, the driving device 32 is independently arranged relative to the locking piece 31 in the first position, the force of the driving device 32 on the locking piece 31 disappears, and the locking piece 31 is inserted into the locking groove 21 under the action of its own elastic force to limit the key post 2 from separating from the insertion slot 11, thereby locking the key post 2 to the seat body 1; when the driving device 32 moves to the second position, the driving device 32 acts on the locking piece 31, and the driving device 32 drives the locking piece 31 to overcome its own elastic force to separate from the locking groove 21, so that the key post 2 is unlocked from the seat body 1.
[0036] Therefore, the key locking device 100 is provided by setting the locking piece 31 and the driving device 32 in cooperation, and by forming the acting force of the driving device 32 on the locking piece 31 in the first position or the second position, the movement state of the locking piece 31 can be controlled to lock the key column 2 to the seat body 1 or unlock the key column 2 from the seat body 1, effectively avoiding the operation of directly inserting or separating the output end 321 of the driving device 32 into or from the locking groove 21 to lock or unlock, thereby reducing the stress on the output end 321 of the driving device 32, effectively avoiding damage to the driving device 32, and the problem of poor locking.
[0037] In some embodiments, as Figures 2 to 5As shown, the locking assembly 3 further comprises a blocking piece 33, the blocking piece 33 is connected with the locking piece 31, and the output end 321 of the driving device 32 is at least partially arranged opposite to the blocking piece 33. When the output end 321 of the driving device 32 is not extended, the output end 321 is in a first position, the output end 321 of the driving device 32 is separated from the blocking piece 33, and the locking piece 31 is inserted into the locking slot 21 under the elastic action of itself to limit the key column 2 from being separated from the insertion slot 11. When the output end 321 of the driving device 32 is extended, the output end 321 is in a second position, the output end 321 of the driving device 32 pushes the blocking piece 33 and the locking piece 31 to move away from the locking slot 21 to be separated from the locking slot 21. It should be noted that the extension direction of the output end 321 of the driving device 32 is consistent with the moving direction of the locking piece 31, so that when the output end 321 of the driving device 32 is extended, the output end 321 can drive the blocking piece 33 and the locking piece 31 to move away from the locking slot 21 to be separated from the locking slot 21. Since at least a part of the output end 321 of the driving device 32 is arranged opposite to the blocking piece 33, the action of the driving device 32 will affect the state of the blocking piece 33. When the output end 321 of the driving device 32 is not extended, the blocking piece 33 will not be subjected to the pushing force from the driving device 32, so that the blocking piece 33 and the locking piece 31 connected thereto will remain in the original position unchanged. Under the elastic action of the locking piece 31 itself, the locking piece 31 will be firmly inserted into the locking slot 21 to prevent the key column 2 from being easily pulled out of the insertion slot 11, thereby maintaining the locked state. When unlocking is needed, the output end 321 of the driving device 32 starts to extend, and as the output end 321 of the driving device 32 extends, the output end 321 directly contacts the blocking piece 33 and applies a pushing force to push the blocking piece 33 and the locking piece 31 connected thereto to move away from the locking slot 21 to pull out the locking piece 31 from the locking slot 21, thereby releasing the restriction on the key column 2 and achieving the unlocking operation of the key column 2. Therefore, the locking assembly 3 cleverly realizes the conversion of the locking and unlocking functions through the interaction between the blocking piece 33 and the driving device 32, as well as the insertion and separation actions of the locking piece 31 under the elastic action, which not only ensures safety but also facilitates operation.
[0038] In some embodiments, the driving device 32 and the locking piece 31 are arranged side by side, and the blocking piece 33 extends outward in the radial direction of the locking piece 31, so that when the output end 321 of the driving device 32 is extended, the output end 321 can push the blocking piece 33 to drive the locking piece 31 to move. Wherein, the driving device 32 and the locking piece 31 are arranged side by side, which reduces the space occupation, making the whole device more compact, and the blocking piece 33 extends outward in the radial direction from the side wall of the locking piece 31, so that when the output end 321 of the driving device 32 is extended, the output end 321 can push the blocking piece 33 to drive the locking piece 31 to move.
[0039] In some embodiments, the opening direction of the locking groove 21 intersects with the insertion direction of the key post 2, i.e. the opening direction of the locking groove 21 is not the same direction as the insertion direction of the key post 2, preferably, the opening direction of the locking groove 21 is perpendicular to the insertion direction of the key post 2, specifically, the housing 1 is provided with the insertion slot 11 in the transverse direction, the outer wall of the key post 2 is radially recessed to form the locking groove 21, the housing 1 is provided with the locking hole 12 in the vertical direction, the locking member 31 is also vertically arranged, wherein the housing 1 is provided with a locking cavity below the locking hole 12, the locking member 31 moves up and down along the locking cavity, the housing 1 is provided with a driving cavity on one side of the locking cavity, the driving device 32 is located in the driving cavity, and the blocking member 33 extends from the locking cavity to the driving cavity. The locking groove 21 is a square groove, and one end of the locking member 31 inserted into the locking groove 21 is in a square structure matching the shape of the locking groove 21. The square structure of the locking member 31 and the square locking groove 21 provide strong resistance, and in combination with the above-mentioned opening direction of the locking groove 21 being not the same direction as the insertion direction of the key post 2, the key post 2 is difficult to be pulled out of the locking groove 21 even if external force is applied to the key post 2 (such as trying to pull out with pliers) in the non-unlocking state, effectively improving the security of the locked state.
[0040] In some embodiments, as Figure 3As shown, the first end of the key column 2 is provided with a locking hook 22 for hanging a mechanical key, the end face of the second end of the key column 2 is an inclined surface 23, and the locking groove 21 is arranged between the first end and the second end of the key column 2. During the process of inserting the key column 2 into the insertion slot 11, the locking piece 31 is elastically compressed under the guidance of the inclined surface 23, and when the key column 2 is inserted in place, the locking piece 31 is inserted into the locking groove 21 under the elastic action. Wherein, the first end of the key column 2 refers to the end of the key column 2 exposed to the seat body 1, that is, the outer end, and the second end of the key column 2 refers to the end of the key column 2 inserted into the insertion slot 11, that is, the inner end. The first end and the second end of the key column 2 correspond to the opposite ends of the key column 2. It should be noted that the key column 2 is mainly used for installing and locking a mechanical key, including a locking hook 22, a stop piece, an insertion piece and a circuit board. The locking hook 22 is used for hanging a mechanical key, and the stop piece and the insertion piece are used to form a loop with the locking hook 22. They are conventional structures and will not be described in detail here. When the circuit or software fails and the key needs to be taken out urgently, the key can be taken out by directly cutting off the locking hook 22. Wherein, when the key column 2 is inserted into the insertion slot 11, the first end is exposed to the seat body 1, and the second end is built-in in the insertion slot 11. Therefore, during the process of inserting the key column 2 into the insertion slot 11, the design of the inclined surface 23 of the second end enables the key column 2 to gradually guide the locking piece 31 to be elastically compressed when inserted, rather than suddenly hitting or being stuck, thereby improving the smoothness of the push-in locking. When the key column 2 is inserted in place, the locking piece 31 restores to the original shape under the elastic action and is inserted into the locking groove 21 on the key column 2 to form a lock.
[0041] In other embodiments, as Figure 5 and Figure 6As shown, the locking groove 21 is an arc-shaped groove, and the locking piece 31 is inserted into one end of the arc-shaped groove in an arc shape. When the output end 321 of the driving device 32 is extended, it is in the first position, and the output end 321 of the driving device 32 abuts against one end of the locking piece 31 away from the locking groove 21 to limit the locking piece 31 from being separated from the locking groove 21. When the output end 321 of the driving device 32 is not extended, it is in the second position, and the output end 321 of the driving device 32 is separated from the locking piece 31. The force applied to the key post 2 can make the locking piece 31 slide along the locking hole 12 to separate from the locking groove 21. As the locking groove 21 is designed as an arc-shaped groove, and the one end of the locking piece 31 inserted into the locking groove 21 is in an arc shape matching the arc-shaped groove, when the external force is applied to the key post 2, the locking piece 31 can smoothly move along the track of the arc-shaped groove, whether it is locked or unlocked and smoothly exits, and the transition is unobstructed. However, the shape of the locking groove 21 cannot effectively lock the locking piece 31, so the locking state of the locking piece 31 needs to be controlled by the driving device 32. Specifically, the output end 321 of the driving device 32 abuts against one end of the locking piece 31 away from the locking groove 21, so that after the locking piece 31 is inserted into the locking groove 21, even if the external force is applied to the key post 2, the movement of the locking piece 31 is limited due to the resistance of the driving device 32, preventing it from separating from the locking groove 21, thereby achieving the locking state. When the output end 321 of the driving device 32 is not extended, it no longer abuts against the locking piece 31, and the locking piece 31 loses the constraint of the driving device 32. At this time, the force applied to the key post 2 can make the locking piece 31 and the locking groove 21 separate, thereby achieving the unlocking state.
[0042] In some embodiments, as shown in Figure 5 and Figure 6 the movement track of the locking piece 31 is perpendicular to the movement track of the output end 321 of the driving device 32. It can be understood that the perpendicular arrangement of the locking piece 31 and the driving device 32 can reduce the space occupation, making the entire device more compact. Specifically, the seat body 1 is provided with the insertion slot 11 in the horizontal direction, and the seat body 1 is provided with the locking hole 12 in the vertical direction. The locking piece 31 is also vertically arranged, wherein the seat body 1 located below the locking hole 12 is provided with a locking cavity, and the locking piece 31 moves up and down along the locking cavity. The seat body 1 located below the locking cavity is provided with a driving cavity communicating with the locking cavity and arranged horizontally, and the driving device 32 is located in the driving cavity.
[0043] In some embodiments, the driving device 32 is a single-stable electromagnet, which is in an extended state when powered on and in a retracted state when powered off, having the characteristics of good stability, fast response, long service life and higher flexibility. Of course, in other embodiments, the driving device 32 can also be a double-stable electromagnet, which is not particularly limited here. In addition, the driving device 32 can also be other devices capable of forming a straight extension or retraction, such as an electric push rod, etc., which is not particularly limited here.
[0044] In some embodiments, the locking piece 31 is in abutment with the seat body 1 through the elastic member 4, so that the locking piece 31 is elastically arranged on the seat body 1. Among them, in a specific embodiment, as shown in Figures 2 to 4 , the locking piece 31 can be provided with a receiving groove 311, and the elastic member 4 such as a spring is received in the receiving groove 311, and the opposite ends of the elastic member 4 are respectively in abutment with the locking piece 31 and the seat body 1. Alternatively, in other embodiments, as shown in Figure 5 and Figure 6 , the elastic member 4 such as a spring can be sleeved outside the locking piece 31, and the opposite ends of the elastic member 4 are in abutment with the locking piece 31 and the seat body 1.
[0045] In some embodiments, as shown in Figure 2 and Figure 5 , the key column 2 is provided with an induction chip 24, the induction chip 24 stores key information, the seat body 1 is provided with an electric control board 5, after the key column 2 is inserted into the insertion slot 11 to the position, the electric control board 5 can identify the key information on the induction chip 24, and the electric control board 5 is in communication connection with the driving device 32. Among them, the electric control board 5 such as a circuit board is provided with an identification module for identifying the information of the induction chip 24, specifically, the electric control board 5 is connected to one side of the seat body 1 near the inner end of the insertion slot 11 through a connecting column, the electric control board 5 is used to control the state of the driving device 32 to control the locking piece 31 to enter the locking state to lock the key column 2 when the identification result is that the key information code is the matching key information, and is used to control the driving device 32 to switch the state to control the locking piece 31 to enter the release state without locking the key column 2 when the identification result is that the key information is the non-matching key information.
[0046] In some embodiments, as shown in Figure 2 and Figure 5 , the inner end of the insertion slot 11 is provided with a position detection piece 6, and after the key column 2 is inserted into the insertion slot 11 to the position, the key column 2 triggers the position detection piece 6, wherein the position detection piece 6 is a tactile switch arranged on the electric control board 5 such as a circuit board, and the key column 2 triggers the tactile switch after being inserted into the insertion slot 11 to the position, thereby realizing the function of detecting the insertion of the key column 2 to the position.
[0047] In some embodiments, as shown in Figure 2 and Figure 5 The inner end of the slot 11 is provided with an ejection slider 7, which is elastic and slides in the slot 11. When the key column 2 is inserted into the slot 11, the ejection slider 7 is elastically compressed at the inner end of the slot 11. When the locking member 31 is disengaged from the locking groove 21, the ejection slider 7 restores to eject the key column 2 from the slot 11. The inner end of the slot 11 corresponds to the end inside the slot 11, that is, the other end opposite to the slot opening of the slot 11. By providing the ejection slider 7 at the inner end of the slot 11, the ejection slider 7 is elastically compressed at the inner end of the slot 11 when the key column 2 is inserted into the slot 11. Specifically, when the ejection slider 7 is compressed by the key column 2, the end of the ejection slider 7 touches the micro switch on the control panel 5 to realize the function of detecting the insertion of the key column 2. When the control panel 5 identifies that the key information is not matched or the key column 2 needs to be unlocked for use, the ejection slider 7 ejects the key column 2 from the slot 11, which is convenient for taking and makes the operation feel good when the key column 2 is inserted and taken out. Specifically, the seat body 1 is provided with a guide hole near the inner end of the slot 11, the ejection slider 7 is provided with a guide column 71, a top plate 72 and an elastic body 73, the top plate 72 is connected with the guide column 71, the guide column 71 slides through the guide hole, and the opposite ends of the elastic body 73 are respectively abutted against the top plate 72 and the seat body 1.
[0048] In some embodiments, as shown in Figure 7 The seat body 1 can be provided with a plurality of slots 11, each slot 11 can lock a key column 2, and each key column 2 is provided with a locking assembly 3 for locking, so that a plurality of key columns 2 can be locked on one seat body 1, and each slot 11 is arranged in a row.
