Description

Technical Field

[0001] This utility model relates to the field of mortise lock technology, and more specifically, to a mortise lock with adjustable installation thickness. Background Technology

[0002] A mortise lock is a type of door lock, also known as a mortise door lock. Its basic structure consists of three parts: a handle, a lock cylinder, and a lock body. As a common type of door lock, mortise locks are widely used in various buildings due to their compact structure and high security, and are mainly installed on interior doors and security doors.

[0003] Traditional mortise locks have a fixed distance between the cover plate and the lock body due to the overall length of the mortise, which can only fit doors of a specific thickness. Door thickness varies greatly in different scenarios, and existing mortise locks have poor adaptability and are not easy to adjust flexibly. When the door thickness does not match the lock's preset size, the door must be cut or filled, which not only increases the installation difficulty and time, but may also damage the structural integrity of the door, affecting its appearance and service life. Therefore, a mortise lock with adjustable installation thickness is proposed. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a mortise lock with adjustable installation thickness to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mortise lock with adjustable installation thickness, comprising a lock body and a lock body panel fixed to one side of the lock body. The lock body panel facilitates the installation and fixation of the lock body. A mortise is inserted into the middle of the lock body panel. The mortise is a key component connecting the handle and the bolt drive mechanism. The rotation of the handle drives the bolt to extend and retract, thereby locking and unlocking the lock. Symmetrical plates are arranged on both sides of the lock body. The plates are used to fix the lock body to the door, enhancing the connection strength between the lock body and the door, while protecting the door surface from damage during lock body installation. Mounting holes are provided at both ends of the plates. A screw and a bolt are inserted into the middle of the mounting holes. The mounting holes allow the plates to be fixedly connected to the door body by the screw and bolt. By adjusting the screw's insertion depth in the screw, the distance between the two plates can be adjusted to accommodate doors of different thicknesses.

[0006] A handle is rotatably connected to one side of the cover plate, providing a grip for the user. Rotating the handle causes the mortise to rotate, thus operating the lock. A square groove is provided on one side of one end of the handle, allowing the handle to be firmly connected to the mortise rod, ensuring that the rotation of the handle is effectively transmitted to the mortise rod. A fixing hole is provided on the other side of one end of the handle, with a sealing block and a connecting bolt in the center of the fixing hole. The fixing hole allows the connecting bolt to fix the handle to the mortise rod, preventing the handle from detaching from the mortise rod during use. The sealing block seals the fixing hole, preventing dust, moisture, etc., from entering the fixing hole and avoiding rusting and failure of the connecting bolt. The connecting bolt is used to fix the handle to the mortise rod.

[0007] A limiting block is fixedly connected to one end of the mortise, a spring is provided in the middle of the mortise, and insert rods are symmetrically inserted at both ends of the mortise. A limiting slider is fixedly connected to one end of each insert rod, and a threaded hole is provided at the other end of each insert rod. The limiting block restricts the installation position of the mortise within the lock body panel, ensuring the installation accuracy of the mortise. The spring provides elastic support for the insert rod, allowing it to extend and retract flexibly within the mortise while ensuring a tight fit between the insert rod and the square groove of the handle. The insert rod transmits the rotational torque of the handle to the mortise, thereby driving the bolt to extend and retract. The limiting slider restricts the extension and retraction range of the insert rod, preventing it from falling out of the mortise. The threaded hole allows the connecting bolt to be threadedly connected to the insert rod, thus fixing the handle and the insert rod.

[0008] Preferably, the lock body panel has mounting holes at both ends, and the screw and the screw cylinder are respectively inserted into the mounting holes of the two plates. One end of the screw and the screw cylinder is fixedly connected with a screw head. The mounting holes facilitate the installation and fixing of the lock body panel.

[0009] Preferably, the screw and the screw are corresponding, with one end of the screw extending into the inside of the screw and threadedly connected to the screw. The mounting holes are located on both sides of the lock body. By cooperating with the screw and the screw, the distance between the two plates can be adjusted by adjusting the screw's insertion depth inside the screw, thereby adapting to door bodies of different thicknesses.

[0010] Preferably, one end of the insert and one end of the handle correspond to each other, the cross-sectional shape of the insert and the rod is set to square, and the limiting slider is set in the middle of the insert, so that the rod can extend and retract flexibly in the insert, while ensuring that the rod and the square groove of the handle fit tightly.

[0011] Preferably, one end of the insert rod extends into the square groove at one end of the handle, and the size of the insert rod is adapted to the square groove. The insert rod is used to transmit the rotational torque of the handle to the insert core, thereby driving the latch to extend and retract.

[0012] Preferably, one end of the connecting bolt in the inner cavity of the fixing hole extends into the threaded hole and is threadedly connected to the threaded hole. The plug is embedded in the opening of the fixing hole. The threaded hole allows the connecting bolt to be threadedly connected to the insert rod, thereby fixing the handle to the insert rod.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model firstly adjusts the overall length of the insert by setting the insertion rod to drive the limiting slider to compress the spring, thereby adapting to the installation and use of door bodies of different thicknesses. Furthermore, by using the cooperation of the screw and the screw, the screw's screwing depth in the screw cylinder can be adjusted, which facilitates the installation and fixing of the panel and adapts to the door body thickness, improving the usage effect. The setting of the fixing hole allows the connecting bolt to fix the handle to the insertion rod, preventing the handle from detaching from the insertion rod during use and improving the connection strength.

[0015] 2. This utility model also uses a sealing block to seal the fixing hole, preventing dust, moisture, etc. from entering the fixing hole and avoiding the connecting bolts from rusting and failing. The mortise is a key component connecting the handle and the bolt drive mechanism. The rotation of the handle drives the bolt to extend and retract, realizing the locking and unlocking of the lock. The limit block restricts the installation position of the mortise in the lock body panel, ensuring the installation accuracy of the mortise. The limit slider restricts the extension and retraction range of the mortise rod, preventing the mortise rod from falling out of the mortise.

[0016] In summary, through the interaction of the above-mentioned functions, the overall length of the mortise can be easily adjusted to adapt to door bodies of different thicknesses for installation and use. It also facilitates the adjustment of the installation distance of the cover plate, making it convenient for combined installation and use without requiring additional processing of the door body, thus improving the versatility of the lock.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] As attached Figure 1-3 The diagram shows an adjustable mortise lock, comprising a lock body 1 and a lock body panel 2 fixed to one side of the lock body 1. The lock body panel 2 facilitates the installation and fixation of the lock body 1. A mortise 3 is inserted into the middle of the lock body panel 2. The mortise 3 is a key component connecting the handle 8 and the bolt drive mechanism. The rotation of the handle 8 drives the bolt to extend and retract, thereby locking and unlocking the lock. Two symmetrical plates 4 are arranged on both sides of the lock body 1. The plates 4 are used to fix the lock body 1 to the door body, enhancing the connection strength between the lock body and the door body, while protecting the door surface from damage during lock body installation. Mounting holes 5 are opened at both ends of the plates 4. A screw 6 and a screw 7 are inserted into the middle of the mounting holes 5. The mounting holes 5 allow the plates 4 to be fixedly connected to the door body through the screw 6 and screw 7. By adjusting the screw 7's screwing depth in the screw 6, the distance between the two plates 4 can be adjusted to accommodate door bodies of different thicknesses.

[0023] A handle 8 is rotatably connected to one side of the composite plate 4. The handle 8 provides a grip for the user. By rotating the handle 8, the mortise cylinder 3 is rotated, thereby realizing the operation of the lock. A square groove is provided on one side of one end of the handle 8. The square groove allows the handle 8 to be firmly connected to the mortise rod 13, ensuring that the rotation of the handle 8 can be effectively transmitted to the mortise rod 13. A fixing hole 9 is provided on the other side of one end of the handle 8. A sealing block 10 and a connecting bolt are provided in the middle of the fixing hole 9. The fixing hole 9 allows the connecting bolt to fix the handle 8 to the mortise rod 13, preventing the handle 8 from detaching from the mortise rod 13 during use. The sealing block 10 seals the fixing hole 9, preventing dust, moisture, etc. from entering the fixing hole 9 and avoiding the connecting bolt from rusting and failing. The connecting bolt is used to fix the handle 8 to the mortise rod 13.

[0024] A limiting block 11 is fixedly connected to one end of the mortise 3. A spring 12 is provided in the middle of the mortise 3. Insert rods 13 are symmetrically inserted at both ends of the mortise 3. A limiting slider 14 is fixedly connected to one end of the insert rod 13. A threaded hole 15 is provided at the other end of the insert rod 13. The limiting block 11 restricts the installation position of the mortise 3 in the lock body panel 2 to ensure the installation accuracy of the mortise 3. The spring 12 provides elastic support for the insert rod 13, allowing the insert rod 13 to extend and retract flexibly in the mortise 3. At the same time, it ensures that the insert rod 13 and the square groove of the handle 8 are tightly fitted. The insert rod 13 is used to transmit the rotational torque of the handle 8 to the mortise 3, thereby driving the bolt to extend and retract. The limiting slider 14 restricts the extension and retraction range of the insert rod 13 to prevent the insert rod 13 from falling out of the mortise 3. The threaded hole 15 allows the connecting bolt to be threadedly connected to the insert rod 13, thereby fixing the handle 8 and the insert rod 13.

[0025] As attached Figure 1 As shown, mounting holes are provided at both ends of the lock body panel 2. The screw 6 and screw 7 are respectively inserted into the mounting holes 5 of the two cover plates 4. One end of the screw 7 and the screw 6 is fixedly connected with a screw head. The screw 6 and the screw 7 correspond to each other. One end of the screw 7 extends into the inside of the screw 6 and is threadedly connected to the screw 6. The mounting holes 5 are located on both sides of the lock body 1. The mounting holes facilitate the installation and fixing of the lock body panel 2. By cooperating with the screw 6 and the screw 7, the distance between the two cover plates 4 can be adjusted by adjusting the screw 7's screwing depth in the screw 6, thereby adapting to door bodies of different thicknesses.

[0026] As attached Figure 1-3 As shown, one end of the mortise 3 corresponds to one end of the handle 8. The cross-sectional shape of both the mortise 3 and the rod 13 is set as a square. The limiting slider 14 is set in the middle of the mortise 3. One end of the rod 13 extends into the square groove at one end of the handle 8. The size of the rod 13 is adapted to the square groove. One end of the connecting bolt in the inner cavity of the fixing hole 9 extends into the threaded hole 15 and is threadedly connected to the threaded hole 15. The sealing block 10 is embedded in the opening of the fixing hole 9. The rod 13 is used to transmit the rotational torque of the handle 8 to the mortise 3, thereby driving the locking tongue to extend and retract, so that the rod 13 can extend and retract flexibly in the mortise 3, while ensuring that the rod 13 and the square groove of the handle 8 are tightly fitted. The setting of the threaded hole 15 allows the connecting bolt to be threadedly connected to the rod 13, thereby fixing the handle 8 and the rod 13.

[0027] The working principle of this utility model is as follows: When in use, the lock body panel 2 is installed on the side of the door through the mounting hole, so that the lock body 1 is embedded inside the door. Then, the two cover plates 4 are placed on both sides of the door. The mortise 3 is inserted into the middle of the lock body 1, so that the two ends of the mortise 3 pass through the middle of the cover plate 4. The square groove at one end of the handle 8 corresponds to the insertion rod 13, so that the two ends of the insertion rod 13 are inserted into the square groove on one side of the two handles 8.

[0028] Then insert the screw 6 and screw 7 into the mounting holes 5 of the composite plate 4 respectively. According to the thickness of the door, rotate the screw 7 to adjust the screw depth of the screw 7 in the screw 6 so that the distance between the two composite plates 4 matches the thickness of the door. Then insert the connecting bolt into the middle of the fixing hole 9 and into the threaded hole 15 to fix the handle 8 to the plug rod 13. Insert the sealing block 10 into the opening of the fixing hole 9 to complete the installation.

[0029] During installation, the overall length of the insert 3 will be automatically adjusted according to the thickness of the door. Specifically, the insert rod 13 drives the limit slider 14 to squeeze the spring 12, which can adjust the overall length of the insert 3. The limit block 11 can limit the installation position of the insert 3, thereby improving the installation and assembly effect.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
