Description

Technical Field

[0001] This invention relates to the field of safe technology, and more specifically, to a multi-point emergency relocking latch mechanism. Background Technology

[0002] With the increasing demand for security insurance, safes, vaults, and other security devices, serving as the last line of defense, are increasingly being used in people's lives. From ancient caves used to store flint, stone tools, shells, and seeds, to the treasure chests used to store money, clothing, land deeds, documents, medical texts, imperial edicts, military tallies, and the imperial seal, to modern safes used to store gold and silver jewelry, precious stones, documents, and antiques, China has become the world's largest market for both commercial and civilian safes. The development of security devices also reflects economic and scientific progress. To improve the security of these devices, many manufacturers are now adding heavy-duty locking mechanisms to their core structures.

[0003] Application CN201911271701.8 discloses a split-type dual-drive door pin structure, including: a door panel, a main board, the main board being slidably mounted on the inner surface of the door panel; an electric push rod and an execution control board, the electric push rod being mounted on the main board; a door pin fixing plate, the door pin fixing plate having a door pin, which is slidably mounted on one side of the door panel and fixed to the push rod head of the electric push rod, the door being opened / closed by the electric push rod pushing the door pin fixing plate; a main board rack, the main board rack being fixed on the main board, the extension direction of the rack being consistent with the sliding direction of the main board; and a key lock, the key lock including a lock cylinder passing through the door panel and a gear axially fixed to the lock cylinder, the gear meshing with the main board rack, the emergency opening / closing being achieved by turning the gear with a key. This door pin structure eliminates the need for a door handle during emergency opening, and by adding a relocking mechanism, prevents the key lock from being forcibly opened by damage, thus improving overall security.

[0004] However, in actual use, it has been found that safes equipped with emergency unlocking mechanisms have a significantly reduced level of protection. While the current heavy-duty locking mechanisms are sufficient to handle most situations when the safe is forcibly opened, there is still room for improvement, especially for high-value items. The protection level of the safe equipment must be raised to the limit. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a multi-point emergency relocking latch mechanism to solve one or more of the above-mentioned problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A multi-point emergency relocking latch mechanism includes a cabinet with a door lock mechanism, wherein the door lock mechanism is provided with multiple locking mechanisms;

[0008] The front end of the door lock mechanism is provided with a metal front plate and a glass front plate, and the glass front plate is located in front of the metal front plate;

[0009] The right end of the metal front plate is provided with a limiting sliding groove that is symmetrical in the upper and lower parts and runs through the front and back.

[0010] The door lock mechanism is equipped with a metal rear plate at its rear end;

[0011] The multiple locking mechanisms are distributed and installed on the metal rear plate and the metal front plate;

[0012] The trigger end of the multiple locking mechanism passes through the metal front plate and is confined to the glass front plate;

[0013] After the glass front panel breaks, the multi-lock mechanism is triggered and locks the door lock mechanism in both horizontal and vertical directions.

[0014] Furthermore, the door lock mechanism includes

[0015] The door lock moving plate has symmetrical inclined grooves on its left side, and the inclined grooves tend to converge towards the left end. Notch grooves are opened at the top and bottom of the left side respectively.

[0016] A horizontal door tongue is located at the left end of the door lock moving plate, and the other end is embedded in the horizontal door tongue groove of the cabinet.

[0017] The vertical tongue is symmetrically and slidably set in different inclined slots, and the other end is embedded in the vertical tongue slot of the cabinet body;

[0018] Rotate the handle, and its end passes through the cabinet, the glass front panel, the metal front panel, the door lock moving plate in sequence and is rotatably connected to the metal rear panel;

[0019] A switch plate is fixedly mounted on the rotating handle, with a notch at the top and the upper end tilted to the left, located between the door lock moving plate and the metal front plate;

[0020] The switch pin has one end connected to the front of the door lock moving plate and the other end inserted into the notch of the switch plate;

[0021] The rotation of the handle pushes the switch pin and the door lock moving plate to move horizontally, thereby causing the horizontal and vertical door tongues to engage or disengage from the corresponding door tongue slots of the cabinet.

[0022] Furthermore, the left end of the front side of the door lock moving plate is provided with a first pop-out limiting plate that is symmetrically arranged vertically. The first pop-out limiting plate has a through first pop-out limiting groove, which is a groove that is narrower on the left and wider on the right. The first pop-out limiting plate is offset from the multi-lock mechanism.

[0023] Furthermore, a through second pop-out limiting groove is provided at the opposite ends of the two vertical door tongues. The second pop-out limiting groove has a structure that is narrower near the center and wider near the end edge.

[0024] Furthermore, the multi-locking mechanism includes

[0025] A sliding stop is symmetrically and slidably disposed on the back of the metal front plate and slides along the limiting sliding groove. An elastic element in a stretched state is provided between the two sliding stops. An elastic pin passing through the metal front plate is provided on the front of the sliding stop and the elastic pin is engaged in the groove on the back of the glass front plate.

[0026] A pop-out stop is symmetrically positioned on the backward-bending folded plate on the metal front plate. It is connected to the inner side of the end of the folded plate through a compressed elastic element. The front of the pop-out stop passes through the metal front plate through an elastic pin and is embedded in a slot on the back of the glass front plate.

[0027] The pop-out stop is also provided with a through-cavity, which houses a reinforcing spring pin. The front end of the reinforcing spring pin is pressed against the back of the metal front plate by an elastic element, and the rear end of the reinforcing spring pin is pressed against the front of the door lock moving plate. The door lock moving plate is also provided with a through-cavity reinforcing slot, which is perpendicularly aligned with the reinforcing spring pin and the height difference does not exceed the compression amount of the elastic element of the pop-out stop. The reinforcing spring pin is located between the reinforcing slot and the folding plate.

[0028] Furthermore, both the sliding block and the pop-out block are aligned with the door lock moving plate, and the pop-out block is also aligned with the notch groove.

[0029] Furthermore, the multi-locking mechanism also includes

[0030] The first pop-out pin is symmetrically connected to the front of the metal rear plate by an elastic element in a compressed state, and is aligned with the center of the wide groove of the first pop-out limiting groove. It has a column pin structure that is narrow at the front and wide at the back. The maximum width of the first pop-out pin is the same as the maximum width of the first pop-out limiting groove, and the minimum width of the first pop-out pin is not greater than the minimum width of the first pop-out limiting groove.

[0031] The second pop-out pin is symmetrically connected to the front of the metal rear plate by an elastic element in a compressed state, and is aligned with the center of the wide groove of the second pop-out limiting groove. It has a pin structure that is narrow at the front and wide at the back. The maximum width of the second pop-out pin is the same as the maximum width of the second pop-out limiting groove, and the minimum width of the second pop-out pin is not greater than the minimum width of the second pop-out limiting groove.

[0032] Furthermore, both the first ejector pin and the second ejector pin pass through the metal front plate and press against the back of the glass front plate.

[0033] Furthermore, after the elastic element is released, the widest part of the first pop-out pin is engaged in the first pop-out limiting groove, and the widest part of the second pop-out pin is engaged in the second pop-out limiting groove.

[0034] Furthermore, the door lock mechanism also includes

[0035] A safety lock is symmetrically mounted on the metal front plate.

[0036] A locking device is provided on the door lock movable plate;

[0037] The safety lock is vertically aligned with and interlocked with the locking device. A keyhole is provided on the cabinet body, and the keyhole is aligned with and connected to the safety lock.

[0038] In summary, the present invention has the following beneficial effects:

[0039] 1. The cabinet is protected against theft by a combination of multiple methods, including a key-matching safety lock, a door lock mechanism controlled by the door handle, and a multi-lock mechanism that can be triggered under the control of the glass front panel.

[0040] 2. The multi-locking mechanism uses vertical sliding and forward and backward pop-out compression to limit the movable parts of the door lock mechanism controlled by the door handle, providing multi-angle, three-dimensional, misaligned explosion-proof protection.

[0041] 3. The glass front panel cannot be restored after it is broken. Therefore, the device is a one-time trigger structure with no emergency reset mechanism. In an emergency, it can effectively slow down the progress of forced opening of the cabinet and greatly improve the protection level of the latch mechanism. Attached Figure Description

[0053] Example:

[0054] The following is in conjunction with the appendix Figure 1-10 The present invention will be described in further detail below.

[0055] Multi-point emergency relocking latch mechanism, such as Figure 1-6As shown, the main frame is a cabinet 20 with a door lock mechanism 10. Inside the cabinet 20 is the main mechanism—a multi-lock mechanism 30. At the front of the door lock mechanism 10, a glass front plate 50 and a metal front plate 40 are arranged sequentially from front to back; that is, the metal front plate 40 is positioned between the glass front plate 50 and the door lock mechanism 10. At the rear of the door lock mechanism 10 is a metal rear plate 60. The multi-lock mechanism 30 is divided into four parts, which are respectively installed on the metal rear plate 60 and the metal front plate 40. The different structures are mainly installed by bolt connections. The trigger end of the multi-lock mechanism 30 passes through the metal front plate and is restrained on the glass front plate 50. In other words, the multi-lock mechanism 30 is in an abnormal restraint state, restricted by the glass front plate 50. Once the glass front plate 50 breaks, the relevant mechanisms are triggered to restrain the door lock mechanism 10 from both horizontal and vertical directions, thus achieving explosion-proof and anti-theft functions.

[0056] The latch mechanism mainly comprises three protective systems. Two of these systems are located in the door lock mechanism 10: one is a normal safety lock 17 structure that requires a key to open, and the other is a cabinet door structure that is manually opened by a handle. The present invention further adds a multiple locking mechanism 30 to these two systems to protect the existing two protective systems.

[0057] The door lock mechanism 10 includes a door lock moving plate 11, a horizontal latch 12, a vertical latch 13, a rotating handle 14, a switch plate 15, and a switch pin 16. The door lock moving plate 11 is the core of the door lock mechanism 10; it is a horizontally movable plate located between the metal front plate 40 and the metal rear plate 60. The left side of the door lock moving plate 11 has vertically aligned oblique grooves 111, which run from right to left and from top to bottom, meaning the two oblique grooves 111 tend to converge towards the left end. The top and bottom ends of the left side of the door lock moving plate 11 have recessed notches 112, serving as contact points for the subsequent multi-lock mechanism 30 to trigger and restrict the door lock moving plate 11. The horizontal latch 12 is located at the left end of the door lock moving plate 11, and its end can be inserted into the horizontal latch 12 groove of the door cabinet. The vertical door tongues 13 are symmetrically arranged, with one end engaging the corresponding oblique groove 111. The vertical door tongues 13 can slide as a whole, and the other end is also embedded in the vertical door tongue groove of the cabinet. The door tongue and door tongue groove are conventional designs for cabinet door structures and will not be described in detail. The rear end of the rotating handle 14 passes through the cabinet body 20, the glass front panel 50, the metal front panel 40, and the door lock moving plate 11 in sequence, and is rotatably connected to the metal rear panel 60. A switch plate 15 is fixedly installed on the rotating handle 14. The top of the switch plate 15 has a notch, and the notch end of the switch plate 15 is designed to be offset to the left relative to the rotating handle 14. The switch plate 15 is located between the door lock moving plate 11 and the metal front panel 40, and the switch plate 15 and the rotating handle 14 rotate synchronously. A switch pin 16 is provided on the front of the door lock moving plate 11. The front end of the switch pin 16 is inserted into the notch of the switch plate 15. In this way, the door lock moving plate 11 and the rotating handle 14 form a linkage structure through the switch plate 15 and the switch pin 16. That is, the rotation of the rotating handle 14 will drive the switch pin 16 to move together with the door lock moving plate 11, which in turn will drive the horizontal door tongue 12 and the vertical door tongue 13 to be inserted into or removed from the door tongue groove on the door cabinet.

[0058] The door lock mechanism 10 also includes two safety locks 17 disposed on the metal front plate 40. The two safety locks 17 are arranged symmetrically vertically, and each safety lock 17 has a corresponding locking device 18. The two locking devices 18 are arranged symmetrically vertically and opposite to each other on the door lock moving plate 11. The safety locks 17 and the locking devices are vertically aligned and interlocked to form a complete mechanical safety door lock structure. A keyhole is opened on the cabinet 20, which is aligned with the front and back of the safety locks 17. The keyhole is inserted to control the interlocking or unlocking of the key lock and the locking device.

[0059] The multi-locking mechanism 30 has four triggering areas, which are classified into sliding and pop-out vertical plane displacement and forward and backward pop-out horizontal plane displacement according to the locking type.

[0060] In the vertical plane displacement, the multi-locking mechanism 30 corresponds to the sliding block 31 and the pop-out block 32. A symmetrical and continuous limiting sliding groove 41 is provided on the right end of the metal front plate 40. There are two sliding blocks 31, symmetrically arranged on the back of the metal front plate 40, sliding along the limiting sliding groove 41. The sliding blocks 31 are connected by an elastic element. In the untriggered state, the elastic element is stretched and tightened, ensuring that the sliding blocks 31 do not interfere with the movement path of the door lock moving plate 11 and hinder its movement. An elastic pin is provided on the front of the sliding block 31. The elastic pin passes through the metal front plate 40 and is engaged in a slot on the north side of the glass front plate 50, forming a limiting and relocking structure on the right end of the door lock moving plate 11.

[0061] The metal front plate 40 has backward-bending folding plate members 42 at its upper and lower left ends. Two pop-out blocks 32 are connected to the bottom surface of the top of each folding plate member 42 via elastic elements. The elastic elements are in a compressed state. A spring-loaded pin is provided on the front of each pop-out block 32. The spring-loaded pin passes through the metal front plate 40 and is engaged in a slot on the north side of the glass front plate 50, forming a restrictive relocking structure on the left end of the door lock moving plate 11.

[0062] Both the sliding stop 31 and the pop-out stop 32 are aligned with the door lock moving plate 11, meaning that these three are in the same vertical plane and tend to intersect. The pop-out stop 32 must also be aligned vertically with the notch 112.

[0063] In terms of horizontal displacement, the multi-lock mechanism 30 corresponds to the first ejector pin 33 and the second ejector pin 34. The left end of the front of the door lock moving plate 11 is provided with a symmetrically positioned first ejector limiting plate 113. The first ejector limiting plate 113 has a through-hole first ejector limiting groove 114, which is narrower on the left and wider on the right. The first ejector limiting plate 113 is offset from the first ejector pin 33. The first ejector pin 33 is symmetrically connected to the front of the metal rear plate 60 via elastic elements, aligned with the center of the first ejector limiting groove 114. The pin cap is positioned towards the rear, and the overall shape is narrower and longer at the front and wider and shorter at the back. The maximum width of the first ejector pin 33 is the same as the maximum width of the first ejector limiting groove 114, and the minimum width of the first ejector pin 33 must not be less than the minimum width of the first ejector limiting groove 114. This ensures that the first ejector pin 33 has sufficient displacement in the front-to-back direction after being triggered, and that the pin cap is promptly engaged in the first ejector limiting groove 114. The first ejector pin 33 restricts the door lock moving plate 11.

[0064] The structure of the second pop-out pin 34 is similar to that of the first pop-out pin 33, except that the second pop-out limiting groove 131 is formed on the opposite ends of the two vertical tongues 13. The second pop-out limiting groove 131 is narrower on the side near the center and wider on the side near the end. The second pop-out pin 34 restricts the vertical tongues 13.

[0065] The first ejector pin 33 and the second ejector pin 34 both pass through the metal front plate 40 and press against the back of the glass front plate 50.

[0066] In addition, to enhance the stability of the multi-lock mechanism 30, the main limitation is on the door lock moving plate 11 after the pop-out block 32 pops out. Since the door lock moving plate 11 mainly slides left and right, while the pop-out block 32 pops out relative to the center, these two trends are opposite. The elastic element of the pop-out block 32 is easily pulled to the left. The most significant characteristic of an elastic element is its ability to stretch in all directions, which inevitably introduces a certain amount of error in its structure. This means that the door lock moving plate 11 can still actually shift a small distance. To prevent this phenomenon, such as... Figure 10 As shown, a through-cavity is formed at the center of the left side of the pop-out block 32, housing a reinforcing spring pin 321. The length of the reinforcing spring pin 321 is no greater than the depth of the cavity. The front end of the reinforcing spring pin 321 is pressed against the back of the metal front plate 40 by an elastic element, and the rear end is pressed against the front of the door lock moving plate 11, ensuring that the reinforcing spring pin 321 is completely retracted into the cavity in normal operation. Correspondingly, a through-cavity reinforcing slot 115 is also formed on the door lock moving plate, located on the path of the pop-out block 32. This ensures that after the pop-out block 32 is triggered and popped out by the elastic element, the reinforcing spring pin 321 housed in the cavity can change from being in contact with the door lock moving plate 11 to being aligned with the reinforcing slot 115. Due to the removal of the restriction of the door lock moving plate 11, the reinforcing spring pin 321 automatically pops out and extends into the reinforcing slot 115, providing horizontal and left-right blocking reinforcement for the pop-out block 32 and improving the restriction effect.

[0067] When an attempt is made to force the cabinet open, the immense external impact will shatter the internal glass front panel 50, triggering the multiple locking mechanism 30. At this point, the internal structure of the cabinet will... Figure 7-9 As shown, the elastic elements in the four areas release, the first ejector pin 33 ejects forward, and its widest point is engaged in the first ejector limiting groove 114. The second ejector pin 34 also ejects forward, and its widest point is engaged in the second ejector limiting groove 131. The sliding block 31 moves towards the center, intercepting the movement path of the right section of the door lock moving plate 11. The ejector block 32 moves towards the door lock moving plate 11 and is engaged in the notch groove 112, restricting the displacement of the door lock moving plate 11. The multiple locking mechanism 30 restricts the door lock mechanism 10 from four areas. In addition, the interlocking of the safety lock 17 and the locking device 18, and the physical and mechanical structural restrictions of the vertical door tongue 13 and the horizontal door tongue 12, make it difficult to break the safety device and steal the valuables inside in a short time, thus improving the level of protection.

[0068] It should be noted that this specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
