Description

Technical Field

[0001] The utility model relates to the field of lock buckle hands, in particular to a lock buckle hand with unlocking operation. Background Art

[0002] A handle is a component installed on the door body to facilitate opening and closing the door. Common sliding doors with door locks are usually equipped with handles embedded in the door body on both sides.

[0003] With the development of technology, the function of handles is no longer simply limited to facilitating the opening and closing of doors. More and more handles are beginning to be integrated with lock cores, thus integrating the door lock and handle into one, which is more convenient for installation and can effectively save space on the door.

[0004] Among them, the Chinese patent with patent number ZL 202322007424.8 discloses "a hidden sliding door handle, comprising a door lock body, a front cover plate is installed on the front of the door lock body, a lock hole is embedded and installed on the lower edge of the front of the front cover plate, first magnets are embedded and installed on both sides of the front of the front cover plate, a handle front cover is installed on the outer cover of the front cover plate, first magnetic iron sheets are embedded and installed on both sides of the back of the handle front cover, a first handle groove is provided on the upper edge of the front of the handle front cover, a first card hole is opened on the lower edge of the front of the handle front cover, a lock body is installed on the left side of the door lock body, and a rear cover plate is provided on the back of the door lock body. The overall structure is simple, which is convenient for quickly assembling the door lock body and hiding the assembly screws in the front and rear covers of the decorative surface film handle consistent with the sliding door. The overall sliding door handle is better in concealment and installation beauty, and has high stability and practicality, and has certain promotion value."

[0005] Unlike the solution described in the above-mentioned patent, there is a problem with the existing lock handles on the market. Although the lock cylinder and the handle are integrated into a whole, the functions of the two are relatively independent and there is no linkage. Moreover, after the existing lock handle completes the unlocking by inserting the key into the lock cylinder, the door lock is opened and no other unlocking operations are required. This results in the lock handle being unable to cope with the situation where the door does not need to be locked but the door does not want to be opened easily. This also results in the poor applicability of the existing lock handle, and the situations in which it can be used are greatly limited, and it cannot be applied to various situations like ordinary door locks with handles. Summary of the invention

[0006] In order to overcome the disadvantage that the lock buckle handle in the prior art lacks an unlocking operation and thus has poor applicability, the utility model provides a lock buckle handle with an unlocking operation.

[0007] The technical solution of the utility model to solve the technical problem is: a lock buckle hand with unlocking operation, comprising:

[0008] The housing has a hand grip groove on the front side;

[0009] A lock core is rotatably disposed in the housing, and the lock core includes a lock hole exposed at the front side of the housing;

[0010] Also included are:

[0011] A lock rod is rotatably connected to the housing, the lock rod is used to form a connection with the lock tongue, and the rotation of the lock rod can drive the lock tongue to move to achieve locking and unlocking;

[0012] A trigger plate is movably disposed in the trigger groove, the trigger plate is connected to the lock rod, and the lock rod can be driven to rotate by operating the trigger plate;

[0013] A locking assembly, which is arranged between the lock core and the lock rod, the lock core and the locking assembly form a transmission connection, the rotation of the lock core can drive the locking assembly to change its position state, and the locking assembly has at least a locked position state and an unlocked position state;

[0014] When the locking assembly is in the locked position, the locking assembly acts on the locking rod to prevent the locking rod from rotating;

[0015] When the locking assembly is in the unlocking position, the effect of the locking assembly on the locking rod is released, and the locking rod can rotate.

[0016] The specific composition structure of the locking assembly is further that the locking assembly includes a locking plate, the locking plate can swing up and down relative to the locking rod, a locking hole is opened on the locking plate, a locking column is protruding on the outer side wall of the locking rod, the locking column is movably inserted in the locking hole, and the locking hole also includes a narrow section at the top and a wide section at the bottom;

[0017] When the locking plate swings downward, the locking column moves from the wide section of the locking hole to the narrow section;

[0018] When the locking plate swings upward, the locking column moves from the narrow section to the wide section of the locking hole.

[0019] The specific transmission method between the lock core and the locking plate is further that the locking plate can be rotatably mounted on the lock core, and the rear end of the lock core is also connected to a driving plate, a driving groove is provided on the driving plate, and a driven block is protruding from the locking plate. The driven block can move relative to the driving groove, and a driving protrusion is protruding from one end of the driving groove. The rotation of the driving plate can drive the driving protrusion to abut against the driven block, and push the driven block to cause the locking plate to swing.

[0020] The automatic reset structure of the locking plate is further provided with a mounting bracket for passing the lock core in the shell, the locking plate and the driving plate are both located on the rear side of the mounting bracket, a locking clip is also provided on the rear of the mounting bracket, abutment ribs are protruding on the rear side of the mounting bracket, one end of the locking clip forms an abutment fit with the abutment rib, and the other end forms an abutment fit with the side surface of the locking plate, the locking clip acts on the locking plate so that it always has a downward swinging movement tendency.

[0021] The rotational connection between the trigger plate and the shell is further provided in that an upper rotating shaft and a lower rotating shaft are integrally formed on the trigger plate, and both the upper rotating shaft and the lower rotating shaft are rotationally connected to the shell.

[0022] The connection method between the trigger plate and the locking rod is further that a connecting groove is recessed upwardly at the bottom of the lower rotating shaft, and the top of the locking rod is plugged into the connecting groove. A plurality of connecting blocks are also protruded from the top circumference of the locking rod, and the connecting blocks are movably arranged relative to the connecting groove. The groove wall of the connecting groove can form abutment with the connecting block and push the connecting block, so that the locking rod rotates with the lower rotating shaft.

[0023] The transmission process between the trigger plate and the locking rod is further developed. When the trigger plate is operated to unlock the door, the lower rotating shaft on the trigger plate rotates relative to the locking rod, and the connecting block also moves in the connecting groove. In this process, no transmission is formed between the trigger plate and the locking rod, so this stroke of the trigger plate is an empty stroke. When the trigger plate is rotated a certain angle relative to the locking rod, the connecting block moves to the groove wall of the connecting groove and forms an abutment fit. At this time, the trigger plate is continued to be operated to rotate it, and the groove wall of the connecting groove will push the connecting block to move accordingly, and the locking rod can be rotated. At this time, transmission is formed between the trigger plate and the locking rod, and continuing to rotate the trigger plate can drive the locking rod to complete the unlocking.

[0024] The installation position of the locking rod and the trigger plate in the shell is further, a rotating cavity is opened in the shell, the locking rod is inserted into the rotating cavity, the rotating cavity and the hand buckle groove are connected through a swing window, the trigger plate passes through the swing window to extend into the hand buckle groove, and the trigger plate can swing back and forth relative to the swing window.

[0025] The automatic reset structure of the trigger plate is further provided with a reset torsion spring in the rotating chamber, one end of the reset torsion spring abuts against the shell, and the other end of the reset torsion spring abuts against the trigger plate, and the reset torsion spring acts on the trigger plate to make it always have a tendency to swing backward.

[0026] The specific structure in the hand buckle groove is further that a hand buckle tendon is protruding at the groove opening in the hand buckle groove, the hand buckle tendon is located on the side of the hand buckle groove where a swing window is opened, and the hand buckle tendon is located in front of the trigger plate.

[0027] The housing has a further covering structure for the lock rod and the lock core. The housing is also detachably connected with a side cover for covering the lock rod and a rear cover for covering the lock core.

[0028] The specific door opening and closing process with the lock buckle in the utility model:

[0029] When opening the door, the key is inserted into the lock hole of the lock core and the lock core is rotated, so that the lock core drives the driving plate to rotate relative to the locking plate. When the driving protrusion on the driving plate abuts against the driven block on the locking plate, the driving plate continues to rotate and can push the locking plate to swing upward through the driving protrusion, so that the locking column moves from the narrow section in the locking groove to the wide section. At this time, the locking assembly is switched to the unlocked position. At this time, the operator extends his hand into the buckle groove and pulls the buckle plate to make it swing forward. When the buckle plate swings through the idle stroke, the buckle plate continues to rotate and can drive the lock rod to rotate and drive the lock tongue to complete the unlocking. Then, the operator holds the buckle tendon and pulls the door to make it click while pulling the buckle plate, so that the door can be opened.

[0030] When closing the door, the operator first puts his hand into the hand-buckle groove and pulls the trigger plate to make it swing forward, which can make the lock rod rotate and drive the lock tongue to complete the unlocking. Then, the operator holds the hand-buckle tendon while pulling the trigger plate and pulls the door to close it. Then, the trigger plate is released, and the trigger plate swings backward under the action of the reset torsion spring. At this time, the lock rod rotates and resets to drive the lock tongue to complete the locking, and the door closing action can be completed.

[0031] When the door needs to be locked after the lock rod is closed, the key can be inserted into the lock hole of the lock core and the lock core can be turned to drive the rotation to release the push of the locking plate. At this time, the locking plate will swing downward and reset under the action of the locking clip, and the locking column will also move from the wide section in the locking groove to the narrow section, and the locking assembly will switch to the locked position. At this time, even if the operator pulls the trigger plate, although the trigger plate can still swing due to the existence of the idle stroke, the narrow section of the locking groove blocks the rotation of the locking column, so the lock rod cannot rotate, and it cannot drive the lock tongue to unlock.

[0032] The beneficial effects of the utility model are:

[0033] 1. A lock rod for driving the lock tongue is provided, and a trigger plate for driving the lock rod is swung in the trigger groove, so that when the lock buckle is unlocked, not only the lock cylinder needs to be unlocked by a key, but also the trigger plate needs to be operated to drive the lock rod to complete the unlocking. Adding one step of unlocking action can ensure the safety of the lock buckle, thereby improving the applicability of the lock buckle;

[0034] 2. The swing of the hand button has an idle stroke. Therefore, even when the locking assembly is in the locked position, operating the hand button cannot unlock the door but can cause it to rotate, thereby effectively preventing someone from forcibly pulling the hand button when the door is locked and causing damage to the hand button.

[0035] 3. A hand buckle is provided in the hand buckle slot in front of the trigger plate. When the operator puts his hand into the hand buckle slot to operate the trigger plate, he can also hold the hand buckle at the same time, so that the operator can apply force to open the door, which facilitates the operation of the lock buckle and improves the user experience.

[0036] 4. The shell is also provided with a side cover and a rear cover. By opening the side cover and the rear cover, the lock rod and the lock core can be exposed, which can greatly facilitate the maintenance and repair of the lock buckle during subsequent use. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] Combination Figure 3 , Figure 4 and Figure 7 As shown, in this embodiment, an upper rotating shaft 22 and a lower rotating shaft 23 are integrally formed on the trigger plate 5 , and both the upper rotating shaft 22 and the lower rotating shaft 23 are rotatably connected to the housing 1 .

[0054] Among them Figure 5 As shown, in this embodiment, the bottom of the lower rotating shaft 23 is concavely provided with a connecting groove 24, the top of the locking rod 4 is plugged into the connecting groove 24, and a connecting block 25 is convexly provided on the top peripheral side of the locking rod 4. The connecting block 25 is movably arranged relative to the connecting groove 24, and the groove wall of the connecting groove 24 can abut against the connecting block 25 and push the connecting block 25, so that the locking rod 4 rotates with the lower rotating shaft 23. .

[0055] Among them Figure 6 As shown, in the present embodiment, when the trigger plate 5 is operated to unlock, the lower rotating shaft 23 on the trigger plate 5 rotates relative to the locking rod 4, and the connecting block 25 also moves in the connecting groove 24. In this process, no transmission is formed between the trigger plate 5 and the locking rod 4, so this stroke of the trigger plate 5 is an empty stroke. When the trigger plate 5 rotates a certain angle relative to the locking rod 4, the connecting block 25 moves to the groove wall of the connecting groove 24 and forms an abutment fit. At this time, the trigger plate 5 is continued to be operated to rotate it, and the groove wall of the connecting groove 24 will push the connecting block 25 to move accordingly, and the locking rod 4 can be rotated. At this time, transmission is formed between the trigger plate 5 and the locking rod 4, and continuing to rotate the trigger plate 5 can drive the locking rod 4 to complete the unlocking.

[0056] Among them Figure 7 As shown, in this embodiment, a rotating chamber 18 is opened in the shell 1, and the locking rod 4 is inserted into the rotating chamber 18. The rotating chamber 18 and the hand-catch slot 2 are connected via a swinging window 19. The trigger plate 5 passes through the swinging window 19 to extend into the hand-catch slot 2, and the trigger plate 5 can swing back and forth relative to the swinging window 19.

When the trigger plate 5 swings backward under the action of the reset torsion spring 20, the support claws 28 can abut against the inner side of the shell 1 to prevent the trigger plate 5 from continuing to swing backward, thereby preventing the trigger plate 5 from being too close to the bottom of the buckle groove 2.

[0061] The specific door opening and closing process with the lock buckle hand in this embodiment:

[0062] When opening the door, the key is inserted into the lock hole of the lock core 3 and the lock core 3 is rotated, so that the lock core 3 drives the driving plate 11 to rotate relative to the locking plate 6. When the driving protrusion 14 on the driving plate 11 abuts against the driven block 13 on the locking plate 6, the driving plate 11 continues to rotate and can push the locking plate 6 to swing upward through the driving protrusion 14, so that the locking column 8 moves from the narrow section 9 in the locking groove to the wide section 10. At this time, the locking assembly is switched to the unlocking position state b. At this time, the operator extends his hand into the buckle groove 2 and pulls the buckle plate 5 to make it swing forward. When the buckle plate 5 swings through the idle stroke, the buckle plate 5 continues to rotate and can drive the lock rod 4 to rotate and drive the lock tongue to complete the unlocking. Then, the operator holds the buckle tendon 21 and pulls the door to make it click while pulling the buckle plate 5, so as to complete the door opening action.

[0063] When closing the door, the operator first puts his hand into the hand-grip groove 2 and pulls the trigger plate 5 to make it swing forward, so that the lock rod 4 can rotate and drive the lock tongue to complete the unlocking. Then, the operator holds the hand-grip tendon 21 while pulling the door to close it, and then releases the trigger plate 5. The trigger plate 5 swings backward under the action of the reset torsion spring 20. At this time, the lock rod 4 rotates and resets to drive the lock tongue to complete the locking, and the door closing action can be completed;

[0064] When the lock rod 4 needs to be locked after closing the door, the key can be inserted into the lock hole of the lock cylinder 3 and the lock cylinder 3 can be rotated to release the push of the locking plate 6. At this time, the locking plate 6 will swing downward and reset under the action of the locking clip 16, and the locking column 8 will also move from the wide section 10 in the locking groove to the narrow section 9, and the locking assembly will switch to the locked position state a. At this time, even if the operator pulls the trigger plate 5, although the trigger plate 5 can still swing due to the existence of the idle stroke, the narrow section 9 of the locking groove blocks the rotation of the locking column 8, so the lock rod 4 cannot rotate, and it cannot drive the lock tongue to unlock.

[0065] The advantage of this embodiment is that a locking rod connected to the lock tongue is arranged in the shell, and the locking rod is driven by a trigger plate located in the trigger groove, so that during the unlocking process of the lock trigger, not only the lock cylinder needs to be unlocked by a key, but also the trigger plate needs to be triggered by hand to complete the unlocking. Adding this operation can make the lock trigger safer and more applicable.

[0066] The above specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
