Description

Technical Field

[0001] This utility model relates to the field of door lock technology, and more specifically, to a minimalist door lock with a key. Background Technology

[0002] A door lock, as the name suggests, is a tool used to lock a door to prevent others from opening it. There are many types of door locks, and the requirements for door locks vary in different situations. Ordinary households generally use anti-theft door locks, which are highly secure and relatively inexpensive. Currently, most commonly used door locks are equipped with a handle and a lock base. The handle is rotated and mounted on the lock base, which is then fixed to the door body with screws. Furthermore, current door locks consist of a lock body, fasteners, a handle assembly, and a lock cylinder assembly. The lock body is embedded in the door panel and fixed with fasteners.

[0003] Most door locks have complex structures, resulting in the presence of door handles and lock seats on the door panel after installation. This leads to a lower overall aesthetic appeal and simplicity, failing to meet the current demand for modern minimalism.

[0004] Currently, there are some minimalist door locks on the market, consisting of four parts: lock body, outer handle, inner handle, and transmission rod. The lock body is inserted into a slot in the door panel. The inner and outer handles are connected by the transmission rod passing through the lock body. A push block on the inner handle drives a locking block fixedly connected to the push block to move linearly, thereby realizing the locking and unlocking functions. When installed on the door panel, only the handle is exposed, which is more aesthetically pleasing and simple.

[0005] However, this minimalist door lock does not have a lock cylinder assembly, and the lock's clutch function can only be operated from the inside handle, which cannot meet the user's needs. Utility Model Content

[0006] The purpose of this utility model is to provide a minimalist door lock that can meet user needs and improve user experience.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] This utility model provides a minimalist keyless door lock, including a lock body, an outer handle, an inner handle, and a transmission rod.

The term "connection" can refer to a direct connection or an indirect connection via intermediate components (elements). The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments". Definitions of other terms will be given in the following description.

[0035] It should be noted that the concepts of "first" and "second" mentioned in this utility model are only used to distinguish between devices, modules or units, and are not used to limit these devices, modules or units to necessarily be different devices, modules or units, nor are they used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0036] See Figures 1 to 11This utility model provides a minimalist door lock with a key, including a lock body 100, an outer handle 200, an inner handle 300, a transmission rod 500, and a lock cylinder assembly 400. The outer handle 200 and the inner handle 300 each include a handle head and a handle integrally formed with the handle head. The handle heads of the two are distributed on both sides of the lock body 100 and connected by the transmission rod 500. The lock cylinder assembly 400 is, for example, a pin tumbler lock cylinder, which is located inside the outer handle 200, and a keyhole (not shown, the same below) is exposed on the handle head 211 of the outer handle 200.

[0037] Please combine Figure 6 The transmission rod 500 is provided with a push block 521, a locking block 522 and a transmission column 523 in sequence along its length. The push block 521 is located at one end of the transmission rod 500, the transmission column 523 is located at the other end of the transmission rod 500, and the locking block 522 is located in the middle of the transmission rod 500 and can slide along the length of the transmission rod 500 to engage or disengage with the clutch block 110 in the lock body 100 when the push block 521 or the transmission column 523 is pushed.

[0038] It should be noted that, please refer to... Figure 9 When the locking block 522 engages with the clutch block 110, rotating the handle 212 can cause the bolt inside the lock body 100 to extend or retract, thereby unlocking or locking the door. When the locking block 522 disengages from the clutch block 110, rotating the handle will cause the transmission rod 500 to spin freely and will not cause the bolt of the lock body 100 to extend or retract, and the lock will be in a locked state.

[0039] Please combine Figure 2 The lock cylinder assembly 400 includes a lock cylinder body 410 and a drive cylinder 420 connected axially.

[0040] The lock cylinder body 410 includes an outer lock cylinder and an inner lock cylinder rotatably embedded in the outer lock cylinder. The outer lock cylinder is fixed inside the handle head of the outer handle 200. The inner lock cylinder has a keyhole into which a matching key can be inserted to drive the inner lock cylinder to rotate relative to the outer lock cylinder.

[0041] The drive cylinder 420 is a cylindrical shape with a drive hole 421 on its peripheral wall. The drive cylinder 420 is connected to the inner lock cylinder of the lock cylinder body 410 away from the keyhole and can rotate synchronously with the key. The transmission column 523 abuts against the inner wall of the drive hole 421 and slides along the inner wall of the drive hole 421 when the drive cylinder 420 rotates, causing the locking block 522 to engage or disengage from the clutch block 110.

[0042] Correspondingly, the handle head of the inner handle 300 is provided with a clearance hole for the push block 521. The push block 521 protrudes from the clearance hole for the user to push, thereby driving the locking block 522 to move linearly.

[0043] In one embodiment, the drive cylinder 420 has an end plate at one end facing the lock cylinder body 410, and an insertion hole 422 is provided on the end plate. The lock cylinder body 410 has an insertion protrusion 411 at one end away from the keyhole, and the insertion protrusion 411 is inserted into the insertion hole 422.

[0044] In one embodiment, the drive hole 421 is a quadrilateral hole, and the transmission column 523 is slidably switched to abut against a pair of diagonals with the longer diagonal of the quadrilateral hole.

[0045] Optionally, two sides of the quadrilateral hole are horizontally arranged on the drive cylinder 420, and the two parallel sides are arranged along the axis of the drive cylinder 420 and are parallel to the end face of the drive cylinder 420; the other two sides are inclinedly arranged on the peripheral wall of the drive cylinder 420, and their side lengths may be the same or different.

[0046] Please combine Figure 10 and Figure 11 When the lock is locked, the locking block 522 is separated from the clutch block 110, the pushing block 521 is located on the side of the inner handle 300 away from the outer handle 200, the keyhole is tilted to the upper left, and the transmission column 523 abuts against the corner of the drive hole 421 away from the keyhole. When it is necessary to open the lock, the locking block 522 and the clutch block 110 need to be engaged first. At this time, by inserting the key into the keyhole, the key can drive the inner lock cylinder and the drive cylinder 420 to rotate to the right, thereby creating a relative displacement between the drive cylinder 420 and the transmission column 523. The transmission column 523 slides along the inner wall of the drive hole 421 from a corner away from the keyhole to a corner close to the keyhole, so that the drive cylinder 420 drives the transmission column 523 to move along the length direction, thereby driving the locking block 522 to engage with the clutch block 110 of the lock body 100. At this time, the handle can be rotated to retract the lock tongue of the lock body 100, thereby unlocking. After unlocking, the push block 521 is located on the inner handle 300 near the outer handle 200, with the keyhole tilted to the upper right. Figure 1 As shown.

[0047] When the lock is in the open state and needs to be locked, the inner lock cylinder and drive cylinder 420 are turned to the left by the key, so that the transmission rod 523 slides along the inner wall of the drive hole 421 from one corner near the key hole to one corner away from the key hole, thereby causing the locking block 522 to separate from the clutch block 110 of the lock body 100. At this time, when the handle is turned, the transmission rod 500 will spin freely and the lock tongue will not retract into the lock body 100.

[0048] It should be noted that during the opening process of the lock, the transmission column 523 slides along a horizontal side and a diagonal side away from the keyhole to a corner end near the keyhole; during the locking process of the lock, the transmission column 523 slides along a horizontal side and another diagonal side near the keyhole to a corner end away from the keyhole.

[0049] In addition, the above embodiments use a quadrilateral drive hole 421 to illustrate the working process of the drive hole 421 of this application, but it does not mean that the drive hole 421 can only be a quadrilateral hole. The drive hole 421 can also be other shapes that can cause the transmission column 523 to move back and forth along the axial direction of the drive cylinder 420. The quadrilateral drive hole 421 should not be regarded as a limitation on the structure of the drive hole 421.

[0050] Please combine Figure 2 and Figure 4 In one embodiment, the outer handle 200 is further provided with a hollow handle pad 220. The handle pad 220 includes an integrally formed mounting base 221 and a guide block 222. The mounting base 221 is used to fix the handle head. The guide block 222 is generally cylindrical and has a guide notch 2221 extending along the axial direction of the guide block 222. The guide block 222 is inserted into the drive cylinder 420. The transmission rod 500 passes through the handle pad 220. The transmission column 523 is embedded in the guide notch 2221 and slides along the guide notch 2221, thereby limiting the transmission column 523 to slide linearly along the guide notch 2221, and further limiting the transmission column 523 to slide along the length direction of the transmission rod 500, so as to prevent the transmission rod 500 from rotating synchronously when the drive cylinder 420 rotates.

[0051] In one embodiment, the guide notch 2221 is formed along one end face of the guide block 222 away from the mounting base 221 and extends toward the mounting base 221.

[0052] Please combine Figure 3 In one embodiment, the handle head 211 is provided with a mounting cavity 2111. The end of the mounting cavity 2111 away from the lock cylinder body 410 forms a first step 2112 inward. A threaded mounting hole is provided on the first step 2112. The mounting seat 221 abuts against the first step 2112 and is connected to the threaded mounting hole by means of a screw.

[0053] In one embodiment, a limiting step 2222 is formed on the outer periphery of the end of the guide block 222 that is connected to the mounting base 221, and the end of the drive cylinder 420 abuts against the limiting step 2222.

[0054] In one embodiment, the handle head 211 has a second step 2113 formed on the inner side of one end of the lock cylinder body 410. A flange 412 is formed on the outer periphery of the end of the lock cylinder body 410 near the drive cylinder 420. The end of the lock cylinder body 410 with the keyhole protrudes from the first step 2112, and the flange 412 abuts against the second step 2113, thereby completing the limiting of the lock cylinder body 410.

[0055] By setting limit steps 2222, first step 2112 and second step 2113, and setting flange 412 on lock cylinder body 410, the positioning of lock cylinder body 410, drive cylinder 420 and handle pad 220 in handle head is completed, avoiding axial displacement of inner lock cylinder and drive cylinder 420 during rotation, achieving precise transmission on the one hand, and reducing noise on the other.

[0056] Please combine Figure 2 and Figure 6 In one embodiment, the transmission rod 500 includes a groove 510 with a mounting groove and a rod 520 embedded in the mounting groove and slidable relative to the groove 510. The pushing block 521, the locking block 522 and the transmission column 523 are all provided on the rod 520.

[0057] In one embodiment, the locking block 522 is integrally formed with the rod body 520, and the pushing block 521 and the transmission column 523 are detachably connected to the rod body 520. By detachably assembling the pushing block 521 and the transmission column 523 with the rod body 520, different pushing blocks 521 and transmission columns 523 can be replaced to adapt to the needs of locks of different specifications and to meet the different aesthetic needs of users.
