Description

Technical Field

[0001] This utility model relates to the field of lock technology, specifically to a quick-install lock. Background Technology

[0002] Existing locks, especially those for interior doors, consist of a first handle mounted on a first panel and a second handle mounted on a second panel. During installation, the first and second handles are typically linked by a lock bar, and the first and second panels are connected and secured to the door body and latch assembly by bolts. This system presents the following problems.

[0003] 1. If the first and second handles are damaged, the first and second panels need to be removed to replace the handles. In addition, the bolts are exposed on the front of the first or second panel.

[0004] Second, some interior doors, such as bathroom doors, are mostly composed of glass and aluminum profile frames. Since the thickness and shape of the aluminum profiles used in different door bodies are different, the gap between the second and first panels of the lock and the aluminum profile is uncontrollable after the second and first panels are installed. When the gap is less than zero, the lock cannot be installed, and when the gap is too large, it is not aesthetically pleasing.

[0005] Third, most interior door locks only have an inner deadbolt function, while the outer deadbolt cannot be activated, making it impossible to quickly open the interior door in an emergency. Although some interior door locks do have an outer deadbolt function, they still require a key to unlock. In an emergency, the key is still needed to unlock the door. Utility Model Content

[0006] The purpose of this invention is to provide a quick-install lock with a handle and panel that can be installed separately.

[0007] The purpose of this utility model is achieved as follows.

[0008] A quick-install lock includes a first handle assembly, a second handle assembly, a lock bar, and a first panel assembly, a second panel assembly, and a latch assembly pre-installed on a door. The first handle assembly and one end of the lock bar are detachably connected and fixed. The second handle assembly contains a self-locking device, which includes a first fixed seat, a second fixed seat, at least one self-locking plate, and a self-locking spring. One of the opposing surfaces of the first and second fixed seats is a self-locking inclined surface, and the other is a flat surface. The self-locking spring and the self-locking plate are disposed between the first and second fixed seats. The self-locking spring causes the self-locking plate to tilt towards the self-locking inclined surface. The first fixed seat, the second fixed seat, and the self-locking plate are respectively provided with an axially aligned first lock hole, a second lock hole, and a third lock hole. The other end of the lock bar passes through the first panel assembly, the latch assembly, and the second panel assembly and is inserted into the first lock hole. When the lock bar passes through the third lock hole, the lock bar's thrust causes the self-locking plate to move towards the flat surface and align itself. The lock bar passes through the third lock hole and is inserted into the second lock hole. After the lock bar stops, the self-locking spring pushes the self-locking plate to tilt, causing the third lock hole to tilt and lock the lock bar.

[0009] Furthermore, the second handle assembly includes a second handle seat and a second handle body. The outer end face of the second handle seat and the inner side of one end of the second handle body are connected and fixed. A self-locking mounting cavity is formed between the second handle seat and the second handle body. The first fixing seat and the second fixing seat abut against the two ends of the mounting cavity, respectively. The side with the smallest gap between the self-locking inclined surface and the plane is clamped to one side of the self-locking piece. The plane with the largest gap between the self-locking inclined surface and the plane is provided with a fixing groove. The fixing groove is parallel to the lock bar. The self-locking spring is set in the fixing groove. One end of the self-locking spring abuts against the bottom surface of the fixing groove. The self-locking spring extends out of the fixing groove and abuts against the self-locking piece.

[0010] The first and second fixed seats limit the tilt angle of the self-locking plate, and the self-locking spring keeps the self-locking plate tilted to lock the lock bar.

[0011] Furthermore, the first and second fixed seats have a positioning protrusion on the side with the smallest distance between the self-locking inclined surface and the plane, and a positioning slot on the other side. The corresponding self-locking piece has a clearance notch. The positioning protrusion passes through the clearance notch and is inserted into the positioning slot. The self-locking piece swings relative to the positioning protrusion through the clearance notch.

[0012] The positioning protrusion and positioning slot realize the positioning and assembly of the first fixed seat, the second fixed seat and the self-locking piece, and restrict the swing direction of the self-locking piece, so as to facilitate the self-locking piece to lock the lock bar.

[0013] Furthermore, the self-locking mounting cavity and the self-locking device are connected in a limiting manner, and the second handle seat is provided with a fourth locking hole, which aligns with the second locking hole. The self-locking device is not easily rotated on its own, thus facilitating the alignment and insertion of the lock bar.

[0014] Furthermore, the first fixed base is provided with a positioning pin, and the second handle base is provided with a positioning hole. The positioning pin is inserted into the positioning hole to form the limiting connection.

[0015] The self-locking device and the self-locking mounting cavity limiting structure are simple and easy to assemble.

[0016] Furthermore, there are two self-locking plates. The side of the second handle assembly is provided with an unlocking socket that connects to the self-locking mounting cavity. The inner end of the unlocking socket faces the side with the largest distance between the self-locking inclined surface and the plane. When a foreign object is inserted into the unlocking socket, the self-locking plate is aligned and the lock bar is disengaged from the second lock hole.

[0017] Multiple self-locking plates enhance the stability of the locking bar. Meanwhile, the unlocking jack design makes it easy to align the self-locking plates, allowing the first and second handle components to be separated after self-locking, facilitating lock replacement.

[0018] Furthermore, the first handle assembly includes a first handle base and a first handle body. The outer end face of the first handle base is provided with a second mounting groove. The first handle base is provided with a fifth locking hole. The side of the first handle base is provided with a first fastening screw hole that communicates with the fifth locking hole. A first fastening screw is provided in the first fastening screw hole. The side of the lock bar is provided with a first fastening hole. The lock bar is inserted into the fifth locking hole. The first fastening hole is aligned with the first fastening screw hole. The first fastening screw is tightened. The tail of the first fastening screw is inserted into the first fastening hole.

[0019] The lock bar and the first handle base are quick and easy to install and assemble.

[0020] Furthermore, the lock bar has a square cross-section.

[0021] This invention allows the first and second handle components to be connected via a locking strip and a self-locking device, eliminating the need for tools and simplifying installation. Furthermore, the locking strip can only be inserted into the self-locking device, reducing the distance between the first and second handle components and ensuring they fit snugly against both sides of the door, enabling rapid installation. The first and second panel components are pre-installed with the door, while the first and second handle components are installed on-site, shortening construction time. Attached Figure Description

One end of the button 121 is linked to the deadbolt block 11, and the inner end of the push rod 8 is linked to the deadbolt block 11.

[0031] See Figure 6 and Figure 7As shown, in this embodiment, the first handle assembly 100 includes a first handle seat 14 and a first handle body 13. The inner side of the first handle body 13 is provided with a first mounting groove 131. Both sides of the first mounting groove 131 are provided with shaft grooves 132 and limiting grooves 133, which communicate with each other. The outer side of the first handle body 13 is provided with a first clearance hole 134 communicating with the first mounting groove 131. The outer end face of the first handle seat 14 is provided with a second mounting groove 141. The inner end face of the first handle seat 14 is provided with a second clearance hole 142 communicating with the second mounting groove 141 and a fifth locking hole 143. The outer end face of the first handle seat 14 is provided with a groove 144 on one side of the second mounting groove 141, with its opening facing the limiting groove 133. The bottom surface of the groove 144 is provided with a clearance groove 145 corresponding to the swing portion 129. The groove 144 is provided with third mounting grooves 146 on both sides corresponding to the clearance groove 145. The outer end face of the first handle base 14 and the inner side of one end of the first handle body 13 are fixed by screws. The first mounting groove 131 and the second mounting groove 141 are connected to form the mounting cavity 101. The button 121 is limited to rotating within the first mounting groove 131. The outer end of the button 121 extends out of the first handle body 13 through the first clearance hole 134. The deadbolt 11 is limited to moving within the second mounting groove 141. The deadbolt pin 111 of the deadbolt 11 extends into the second clearance hole 142.

[0032] The first handle base 14 has a first fastening screw hole 147 on its side that connects to the fifth lock hole 143. A first fastening screw 148 is provided in the first fastening screw hole 147. The lock bar 700 has a first fastening hole 702 on its side. The lock bar 700 is inserted into the fifth lock hole 143. The first fastening hole 702 is aligned with the first fastening screw hole 147. The first fastening screw 148 is tightened. The tail of the first fastening screw 148 is inserted into the first fastening hole 702, so that the first handle assembly 100 and the lock bar 700 are detachably connected at one end.

[0033] The rocker switch assembly 12 also includes a rotating shaft 122, a limiting shaft 123, a push rod 124, and a limiting spring 125. The two sides of the middle portion of the button 121 are rotatably connected via the rotating shaft 122 and the shaft groove 132. A swing portion 129 extends downward from the bottom surface of the middle portion of the button 121, and the limiting shaft 123 is fixedly mounted on the swing portion 129. The limiting spring 125 and the push rod 124 are disposed within the third mounting groove 146. The elastic force of the limiting spring 125 pushes the top of the push rod 124 to protrude from the bottom surface of the groove 144. When the button 121 rotates around the rotating shaft 122, the swing portion 129 swings within the clearance groove 145, causing the limiting shaft 123 to move within the groove 144. In the unlocked state, the limiting shaft 123 is on one side of the push rod 124. In the locked state, the moving limiting shaft 123 presses the push rod 124 back into the third mounting groove 146 and overcomes the elastic force of the limiting spring 125, thereby moving to the side of the push rod 124.

[0034] A first linkage shaft 126 is provided at the bottom of one end of button 121, and the first linkage shaft 126 is rotatably connected to the top of linkage rod 127.

Preferably, the deadbolt pin 111 is a metal deadbolt pin 111.

[0036] The first panel assembly 200 includes a first lock box 21 and a first decorative cover 22. The inner side of the first decorative cover 22 has a first movable groove 221, and the side of the first movable groove 221 has a first protruding buckle 222. The upper and lower sides of the first lock box 21 have first L-shaped slots 211. The first protruding buckle 222 is inserted into the first L-shaped slot 211, and the first lock box 21 is placed within the first movable groove 221. The tail of the first decorative cover 22 and the first lock box 21 are connected by a first adjusting screw 224. Specifically, the tail of the first lock box 21 has a first screw hole 212, and the first lock box 21 has a first clearance cavity 213 corresponding to the first screw hole 212. The first decorative cover 22 has a first countersunk hole 223. The tail of the first adjusting screw 224 passes through the first countersunk hole 223 and is threadedly connected to the first screw hole 212, and the head of the first adjusting screw 224 is placed within the first countersunk hole 223. The thickness of the head of the first decorative cover 22 decreases inward from back to front, forming a first abutment surface 20 on the end face of the head of the first decorative cover 22. In this embodiment, the first lock box 21 is provided with a first reset mechanism that is driven and cooperates with the lock bar 700. The first reset mechanism is prior art and will not be described in detail in this embodiment. The first decorative cover 22 is provided with a first clearance elongated hole 225 corresponding to the lock bar 700. The first lock box 21 is provided with a positioning hole 214 corresponding to the first clearance elongated hole 225.

[0037] The latch assembly 300 is disposed in the drive hole through which the lock bar 700 passes. The latch assembly 300 is prior art and will not be described in detail in this embodiment.

[0038] See Figure 2 and Figure 5As shown, the second panel assembly 400 includes a second lock box 41 and a second decorative cover 42. The inner side of the second decorative cover 42 has a second movable groove 421, and the side of the second movable groove 421 has a second protruding buckle 422. The upper and lower sides of the second lock box 41 have second L-shaped slots 411. The second protruding buckle 422 is inserted into the second L-shaped slot 411, and the second lock box 41 is placed within the second movable groove 421. The tails of the second decorative cover 42 and the second lock box 41 are connected by a second adjusting screw 424. The thickness of the head of the second decorative cover 42 decreases inward from back to front, so that the end face of the head of the second decorative cover 42 forms a second abutment surface 40. Specifically, the second lock box 41 has a second screw hole 412 at its tail end, and a second clearance cavity 413 corresponding to the second screw hole 412. The second decorative cover 42 has a second countersunk hole 423. The tail end of the second adjusting screw 424 passes through the second countersunk hole 423 and the second screw hole 412 and is threadedly connected. The head of the second adjusting screw 424 is placed in the second countersunk hole 423. In this embodiment, the second lock box 41 is provided with a second reset mechanism that is driven and cooperates with the lock bar 700. The second reset mechanism is prior art and will not be described in detail in this embodiment. The second decorative cover 42 has a second clearance elongated hole 425 corresponding to the lock bar 700.

[0039] See Figure 8 and Figure 9 As shown, the second handle assembly 500 has an exposed unlocking hole 50. The second handle assembly 500 contains a self-locking device 600. The second handle assembly 500 includes a second handle base 52 and a second handle body 51. The outer end face of the second handle base 52 and the inner side of one end of the second handle body 51 are connected and fixed. A self-locking mounting cavity 53 is formed between the second handle base 52 and the second handle body 51. The second handle base 52 has a fourth locking hole 54 and a positioning insertion hole 55. The unlocking hole 50, the fourth locking hole 54, and the positioning insertion hole 55 all communicate with the self-locking mounting cavity 53.

[0040] The self-locking device 600 includes a first fixed base 61, a second fixed base 62, two self-locking plates 63, and two self-locking springs 64. One of the opposing surfaces of the first fixed base 61 and the second fixed base 62 is a self-locking inclined surface 611, and the other is a flat surface 621. The self-locking springs 64 and the self-locking plates 63 are disposed between the first fixed base 61 and the second fixed base 62. The self-locking springs 64 cause the self-locking plates 63 to tilt towards the self-locking inclined surface 611. The first fixed base 61, the second fixed base 62, and the self-locking plates 63 are respectively provided with axially aligned first locking holes 610, second locking holes 620, and third locking holes 630. The self-locking device 600 is positioned within the self-locking mounting cavity 53, aligning the fourth locking hole 54 and the second locking hole 620. In this embodiment, the lock bar 700 has a square cross-section, and the corresponding first locking hole 610, second locking hole 620, third locking hole 630, fourth locking hole 54, and fifth locking hole 143 are all square holes. When the self-locking plate 63 is aligned, i.e., in a vertical position, the locking bar 700 can freely pass through the third locking hole 630. If the self-locking plate 63 is tilted, the third locking hole 630 tilts along with the self-locking plate 63, the gap between the locking bar 700 and the third locking hole 630 is eliminated, and the third locking hole 630 restricts the movement of the locking bar 700. The gap between the locking bar 700 and the third locking hole 630 determines the tilt angle required for the self-locking plate 63 to lock.

[0041] Specifically, the first fixing seat 61 and the second fixing seat 62 abut against both ends of the mounting cavity 101, respectively. The side with the smallest gap between the self-locking inclined surface 611 and the plane 621 clamps one side of the self-locking piece 63. The plane 621 with the largest gap between the self-locking inclined surface 611 and the plane 621 is provided with a fixing groove 623, which is parallel to the locking bar 700. A self-locking spring 64 is disposed within the fixing groove 623, with one end of the self-locking spring 64 abutting against the bottom surface of the fixing groove 623, and the self-locking spring 64 extending out of the fixing groove 623 to abut against the self-locking piece 63. One of the first fixing seat 61 and the second fixing seat 62, corresponding to the side with the smallest gap between the self-locking inclined surface 611 and the plane 621, is provided with a positioning protrusion 612, and the other with a positioning slot 622. The corresponding self-locking piece 63 is provided with a clearance notch 631, through which the positioning protrusion 612 passes and inserts into the positioning slot 622. The self-locking piece 63 swings relative to the positioning protrusion 612 through the clearance notch 631.

[0042] In this embodiment, the first fixing base 61 is provided with the self-locking inclined surface 611 and the positioning protrusion 612, and the self-locking inclined surface 611 is inclined away from the second fixing base 62. The second fixing base 62 is provided with the plane 621 and the positioning slot 622. The first fixing base 61 is provided with a positioning pin, which is inserted into the positioning hole 55 to form the limiting connection. The side of the second handle assembly 500 is provided with an unlocking hole 56 that communicates with the self-locking mounting cavity 53, and the inner end of the unlocking hole 56 faces the side with the largest distance between the self-locking inclined surface 611 and the plane 621.

[0043] Preferably, the second handle base 52 has a second fastening screw hole 57 on its side that connects to the fourth lock hole 54. A second fastening screw 58 is provided in the second fastening screw hole 57. The lock bar 700 has a second fastening hole 703 on its side. The lock bar 700 is inserted into the fourth lock hole 54. The second fastening hole 703 is aligned with the second fastening screw hole 57. The second fastening screw 58 is tightened. The tail of the second fastening screw 58 is inserted into the second fastening hole 703, so that the other end of the second handle assembly 500 and the lock bar 700 can be detachably connected, further improving the connection firmness of the first handle assembly 100, the lock bar 700 and the second handle assembly 500.

[0044] In this embodiment, the first panel assembly 200 and the second panel assembly 400 have the same structure and are arranged symmetrically inside and outside the door, that is, the first lock box 21 and the second lock box 41 have the same structure, and the first decorative cover 22 and the second decorative cover 42 have the same structure.

[0045] Universal lock installation process. The latch assembly 300 is installed into the door body, and the first panel assembly 200 and the second panel assembly 400 are respectively placed on the inner and outer sides of the door body. The first fixing box, the latch assembly 300, and the second fixing box are fastened to the door body with bolts. The first decorative cover 22 and the first lock box 21 are snap-fitted together, and the second decorative cover 42 and the second lock box 41 are snap-fitted together. The first decorative cover 22 and the second decorative cover 42 cover the bolts used to connect the first fixing box and the second fixing box.

[0046] The first handle assembly 100 aligns the locking bar 700 through the first clearance elongated hole 225 of the first decorative cover 22, the first lock box 21, the transmission hole of the latch assembly 300, the second lock box 41, and the second clearance elongated hole 425 of the second decorative cover 42 before inserting it into the second handle assembly 500 for connection. Specifically, the locking bar 700 is inserted into the first lock hole 610 from the fourth lock hole 54. When the locking bar 700 passes through the third lock hole 630, the pushing force of the locking bar 700 causes the self-locking plate 63 to move and align towards the plane 621. The locking bar 700 can then pass through the third lock hole 630 and continue to be inserted into the second lock hole 620. After the locking bar 700 stops being inserted, the self-locking spring 64 pushes the self-locking plate 63 to tilt, causing the third lock hole 630 to tilt and lock the locking bar 700. The outer end of the push rod 8 is inserted into the unlocking hole 50. During this process, as the locking bar 700 is inserted, the distance between the first handle assembly 100 and the second handle assembly 500 decreases, thereby achieving a self-locking connection between the first handle assembly 100 and the second handle assembly 500.

[0047] Tighten the first adjusting screw 224. The first adjusting screw 224 pushes the first decorative cover 22 to move, that is, the first decorative cover 22 moves relative to the first lock box 21 within the first L-shaped slot 211. The tail of the first adjusting screw 224 inserts into the first clearance cavity 213, so that the first abutting surface 20 of the head of the first decorative cover 22 abuts against the door body. During the movement of the first decorative cover 22, the lock bar 700 remains within the first clearance elongated hole 225. Tighten the second adjusting screw 424. The second adjusting screw 424 pushes the second decorative cover 42 to move, that is, the second decorative cover 42 moves relative to the second lock box 41 within the second L-shaped slot 411. The tail of the second adjusting screw 424 inserts into the second clearance cavity 413, and the second abutting surface 40 of the head of the second decorative cover 42 abuts against the door body (as shown in the profile). During the movement of the second decorative cover 42, the lock bar 700 remains within the second clearance elongated hole 425. This eliminates the installation gaps between the door body and the first panel assembly 200 and the second panel assembly 400. Generally, the latch assembly 300, the first panel assembly 200, and the second panel assembly 400 are pre-installed on the door body. The first handle assembly 100 and the second handle assembly 500 are then installed subsequently.

[0048] During the disassembly process of the first handle assembly 100 and the second handle assembly 500, an external object (such as a flathead screwdriver) is inserted into the unlocking socket 56 to align the self-locking plate 63, causing the locking bar 700 to disengage from the second locking hole 620. In the accompanying drawings of this embodiment, the self-locking plate 63 has a relatively large tilt angle to facilitate a visual understanding of the self-locking process of the first handle assembly 100 and the second handle assembly 500. In practice, the tilt angle is relatively small, and the self-locking plate 63 will not conform to the self-locking inclined surface 611; that is, a gap is left between the self-locking plate 63 and the self-locking inclined surface 611 for the insertion of an external object.

[0049] Universal lock usage process. The universal lock has a deadbolt state and an unlocked state. In the deadbolt state, pressing button 121 rotates the button 121, which in turn pushes the deadbolt block 11 closer to the bolt assembly 300 via the first linkage shaft 126, linkage rod 127, and second linkage shaft 128. The deadbolt block 11 drives the deadbolt pin 111 to move, extending out of the second clearance hole 142, passing through the first clearance elongated hole 225, and inserting into the positioning hole 214 of the first lock box 21. The positions of the first handle assembly 100 and the first panel assembly 200 are relatively fixed, that is, the first handle assembly 100 cannot be rotated, and consequently the lock bar 700 cannot be rotated, thus achieving the deadbolt purpose. Simultaneously, the rotation of button 121 drives the swing part 129 and the limiting shaft 123 to rotate. The limiting shaft 123 presses the top rod 124 back into the third mounting groove 146 and rotates against the elastic force of the limiting spring 125 until the limiting shaft 123 is located on the right side of the top rod 124. The spring force pushes the top rod 124 to reset. The top rod 124 restricts the movement of the limiting shaft 123 to the left side of the top rod 124, so that button 121 remains in the locked state.

[0050] In the unlocked state, pressing button 121 causes it to rotate in the opposite direction, pulling the anti-lock block 11 away from the latch assembly 300. The anti-lock block 11 then moves the anti-lock pin 111, disengaging it from the positioning hole 214 and the first clearance slot 225 and retracting it into the second clearance hole 142. This allows the first handle assembly 100 to rotate relative to the first panel assembly 200. Simultaneously, the rotation of button 121 causes the swing part 129 and the limiting shaft 123 to rotate. The limiting shaft 123 presses the top rod 124 back into the third mounting groove 146 and rotates against the spring force of the limiting spring 125 until the limiting shaft 123 is located to the left of the top rod 124. The spring force then pushes the top rod 124 back to its original position, restricting the movement of the limiting shaft 123 to the right side of the top rod 124, thus keeping button 121 in the unlocked state.

[0051] In this embodiment, the universal lock is mostly used for interior doors, such as bathroom doors. The first handle assembly 100 is usually located inside the bathroom, and the second handle assembly 500 is located outside the bathroom. The locking and unlocking of the universal lock are achieved through the first handle assembly 100.

[0052] Of course, in special circumstances, by inserting a foreign object into the unlocking hole 50 of the second handle assembly 500, the foreign object pushes the push rod 8 towards the push block, that is, the push rod 8 extends out of the third clearance hole towards the first contact slope. The push rod 8 presses against the first contact slope, causing the push block to move in the opposite direction. The first abutment surface 621 and the second abutment surface 621 disengage, and the first contact slope and the second contact slope come into contact. The elastic force of the anti-lock spring pushes the anti-lock block 11 to reset, that is, the anti-lock pin 111 disengages from the positioning hole 214 and the first clearance elongated hole 225 and retracts into the second clearance hole 142. The first handle assembly 100 can rotate relative to the first panel assembly 200, that is, the second handle assembly 500 can also rotate relative to the second panel assembly 400. This allows for convenient and quick opening of the lock, avoiding damage to the door and the lock.
