Description

Technical Field

[0001] This utility model relates to the field of door and window lock technology, and in particular to a single-cylinder lock structure for doors and windows. Background Technology

[0002] Currently, to enhance the anti-theft performance of single-cylinder locks for doors and windows, a deadbolt structure is usually added to them. For example, Chinese patent literature discloses a technical solution with patent number 202222727066.3 entitled "A double-combination single-cylinder lock for frame-and-screen windows". This solution mainly includes a lock base with a groove, a sliding bar lock slidably disposed in the groove, and two sets of combination wheels rotatably disposed in the groove. The outer wall of the lock base is provided with an operating hole for operating the combination wheels. The combination wheels include an inner wheel and an outer wheel sleeved on the inner wheel. The outer wheel is provided with combination numbers. The inner wheel is provided with a through hole and a limiting notch. The sliding bar lock is provided with a protrusion with a limiting protrusion. The protrusion passes through the through hole, and the limiting protrusion can move in and out of the limiting notch. In use, the outer wheel is turned to rotate the inner wheel. Locking occurs when the limiting protrusion of the convex rod misaligns with the limiting notch of the inner wheel; unlocking occurs when the limiting protrusion of the convex rod aligns with the limiting notch of the inner wheel. However, in practical applications, it still has the following shortcomings:

[0003] First, because the solution uses a combination wheel to open and close the lock, users not only need to remember the password, but also need to get close to see the numbers to unlock it, making blind operation impossible and inconvenient.

[0004] Secondly, to allow the combination wheel to display the combination numbers, through holes, and limiting notches, this design requires splitting the combination wheel into an inner and outer wheel for separate manufacturing. This increases the number of structural components, the number of molds needed, and the overall cost, while also impacting the assembly efficiency of the single-cylinder lock. Furthermore, to ensure the inner wheel rotates with the outer wheel, separate fixing structures are required on both wheels, making the combination wheel's structure extremely complex and increasing the difficulty of development and production.

[0005] Therefore, given the aforementioned shortcomings and deficiencies in existing single-cylinder locks with anti-locking functions, the applicant believes it is essential to optimize and improve their structure in order to better meet people's application needs. Summary of the Invention

[0006] The purpose of this invention is to solve the above-mentioned problems and shortcomings by providing a single-cylinder lock structure for doors and windows with a deadbolt function. This single-cylinder lock structure is equipped with a deadbolt dial with a blocking part. The lock can be opened and closed simply by moving the deadbolt dial forward or backward, enabling blind operation and making the operation of opening and closing the lock more convenient. Furthermore, the deadbolt dial has a simple structure, is easy to develop and produce, and is easier to manufacture.

[0007] The technical solution of this utility model is implemented as follows: a door and window lock structure with a deadbolt function includes a lock base with a groove and a sliding bar lock slidably disposed in the groove. The feature is that it also includes a deadbolt wheel rotatably connected in the groove, and a passage gap is formed between the deadbolt wheel and the groove for the end of the sliding bar lock to slide through. The deadbolt wheel is also provided with a blocking part, and the blocking part can enter or leave the passage gap as the deadbolt wheel rotates, thereby locking or releasing the end of the sliding bar lock. The lock base is also provided with an operating hole for controlling the rotation of the deadbolt wheel.

[0008] Preferably, the anti-locking wheel is an arched wheel structure with a flat rear side, and the upper or lower end of the rear side of the anti-locking wheel constitutes a blocking part.

[0009] Preferably, the present invention further includes a mounting base embedded in the slide groove, the mounting base having mounting grooves respectively communicating with the operating hole and the passage gap, and the anti-locking dial being rotatably connected in the mounting groove.

[0010] Preferably, the mounting groove is provided with a limiting step, and the anti-locking dial is also provided with a limiting protrusion, the limiting protrusion abutting against the limiting step.

[0011] Preferably, the anti-locking dial is further provided with an opening locking groove and a closing locking groove, and the mounting groove is further provided with an elastic positioning element that can be embedded into the opening locking groove or the closing locking groove.

[0012] The beneficial effects of this utility model are as follows: Because the slide groove of this utility model is equipped with a locking dial with a blocking part, the blocking part can be moved in and out of the passage gap simply by moving the locking dial in the forward or reverse direction, thereby blocking or allowing the sliding bar lock to slide. Compared with the existing combination wheel, there is no need to set the combination numbers on the locking dial, yet it can still be used for unlocking and locking, enabling blind operation and making the operation of opening and closing the lock more convenient. Furthermore, through this structural design, the locking dial only needs to have a blocking part to achieve locking and unlocking, which greatly simplifies the structure of the locking dial, reduces the difficulty of its development and production, and makes its manufacturing easier.

[0018] like Figure 1 and Figure 3 As shown, the present invention discloses a door and window lock structure with a deadbolt function, comprising a lock base 1 with a groove 11 and a sliding bar lock 2 slidably disposed in the groove 11. To achieve the purpose proposed by the present invention, it further includes a deadbolt wheel 3 rotatably connected in the groove 11, and a passage gap 12 is formed between the deadbolt wheel 3 and the groove 11 for the end of the sliding bar lock 2 to slide through. The deadbolt wheel 3 is also provided with a blocking part 31, which can enter or leave the passage gap 12 as the deadbolt wheel 3 rotates, thereby locking or releasing the end of the sliding bar lock 2. The front surface of the lock base 1 is also provided with an operating hole 13 for controlling the rotation of the deadbolt wheel 3. The present invention is provided with a deadbolt wheel 3 with a blocking part 31, which can be used to open and close the lock by simply moving the deadbolt wheel 3 in the forward or reverse direction, enabling blind operation and making the operation of opening and closing the lock more convenient. Furthermore, the anti-locking dial 3 has a simple structure, is easy to develop and produce, and is easier to manufacture.

[0019] To further improve the structure of the anti-locking dial 3, such as Figure 5 As shown, the deadbolt wheel 3 is an arched wheel structure with a flush surface 32 on its rear side, and the upper or lower end of the rear side of the deadbolt wheel 3 forms a blocking part 31. Specifically, the lower end of the rear side of the deadbolt wheel 3 is the blocking part 31. This makes the structure of the deadbolt wheel 3 and the blocking part 31 simpler, more scientific and reasonable, and easier to manufacture. Moreover, by setting the deadbolt wheel 3 as an arched wheel structure with a flush surface 32, a passage gap 12 can be created between the flush surface 32 and the slide groove 11 without increasing the size of the slide groove 11, thus making the structure of the single-cylinder lock more compact. At the same time, the blocking part 31 and the deadbolt wheel 3 are an integral structure, resulting in higher structural reliability.

[0020] To make it easier to install the locking dial 3 in the slide groove 11, such as Figure 2 and Figure 3 As shown, the present invention also includes a mounting base 4 embedded in the slide groove 11. The mounting base 4 is provided with mounting grooves 41 that are respectively connected to the operation hole 13 and the passage gap 12. The anti-locking dial 3 is rotatably connected in the mounting groove 41.

[0021] To allow users to quickly know that the barrier 31 has entered the passage gap 12, such as Figure 4 As shown, the mounting groove 41 is provided with a limiting step 42, and the anti-locking dial 3 is also provided with a limiting protrusion 33, which abuts against the limiting step 42. This makes it easier for the user to perceive that the operation has been completed, improving the convenience of use.

[0022] To ensure that the deadbolt 3 can be positioned and maintained in its current state whether it is locking or unlocking, such as... Figures 3 to 5 As shown, the anti-locking dial 3 is also provided with an opening locking groove 34 and a closing locking groove 35, and the mounting groove 41 is also provided with an elastic positioning member 5 that can be embedded into the opening locking groove 34 or the closing locking groove 35. This makes operation more convenient.

[0023] To further improve the structure of the elastic positioning component 5, such as Figure 4 As shown, the mounting groove 41 also has a limiting hole 43 in its groove wall. The elastic positioning element 5 includes a spring 52 and a positioning ball 51 respectively arranged in the limiting hole 43. One end of the spring 52 elastically presses against the bottom of the limiting hole 43, and the positioning ball 51 is disposed at the other end of the spring 52, so that the positioning ball 51 can move in and out of the limiting hole 43 under the elastic pressing action of the spring 52 and can be embedded in the opening locking groove 34 or the closing locking groove 35. Through this structural design, the structure of the elastic positioning element 5 is simpler, more scientific and reasonable, and easier to manufacture.

[0024] To prevent slippage when turning the deadbolt dial 3, such as... Figure 5 As shown, the deadbolt wheel 3 is provided with anti-slip texture 36. This makes the use of the single-cylinder lock more reliable.

[0025] In order for the sliding bar lock 2 to automatically reset after unlocking, such as Figure 2 As shown, a return spring 6 is also provided between the sliding lock 2 and the anti-locking wheel 3 to allow the sliding lock 2 to slide back to its original position. Specifically, the two ends of the return spring 6 press against the mounting base 4 and the sliding lock 2, respectively. This makes operation more convenient.

[0026] To further improve the structure of the sliding bar lock 2, such as Figure 2As shown, the sliding bar lock 2 includes a locking member 21 and a slider 22 disposed at one end of the locking member 21. The locking member 21 is slidably disposed in the groove 11, and the slider 22 is slidably disposed in the passage gap 12. This makes the structure of the sliding bar lock 2 simpler, more scientific and reasonable, and easier to manufacture. Specifically, the slider 22 is an L-shaped block structure composed of a vertical plate and a horizontal plate. The horizontal plate of the slider 22 is disposed at one end of the locking member 21, and the vertical plate of the slider 22 is slidably disposed in the passage gap 12. Through this structural design, the sliding bar lock 2 can be slidably disposed in the passage gap 12 without increasing the size of the groove 11, thus making the structure of the single-bar lock more compact.

[0027] In practical applications, the slider 22 and the locking bar 21 are detachably connected together via a snap-fit ​​structure. Specifically, one end of the locking bar 21 has a snap-fit ​​recess, and the horizontal portion of the slider 22 has a snap-fit ​​protrusion, which snaps onto the snap-fit ​​recess.

[0028] In actual installation, to make it easier and more secure to install the lock base 1 into the pre-drilled holes in the doors and windows, such as... Figure 3 As shown, one end of the lock base 1 is provided with a positioning groove 14, and the other end of the lock base 1 is provided with a telescopic locking mechanism 15. Specifically, the mounting base 4 is located at the upper end of the lock base 1, the positioning groove 14 is located on the mounting base 4, and the telescopic locking mechanism 15 is located at the lower end of the lock base 1. During installation, the positioning groove 14 and the telescopic locking mechanism 15 are respectively engaged on both sides of the pre-drilled mounting holes in the door or window.

[0029] To further improve the structure of the telescopic clamping mechanism 15, such as Figure 3 As shown, the other end of the lock seat 1 is also provided with a slot that extends into the slide groove 11. The telescopic locking mechanism 15 includes a screw connector 151, a push block 152 with a first contact slope 154, and a locking member 153 with a second contact slope 155. The locking member 153 is slidably disposed in the slide groove 11, and the push block 152 is movably disposed in the slide groove 11, with the first contact slope 154 in contact with the second contact slope 155. One end of the screw connector 151 passes through the slide groove 11 and is screwed together with the push block 152, so that by turning the screw connector 151, the push block 152 is moved, and one end of the locking member 153 is pushed out of the slot of the slide groove 11. This makes the telescopic locking mechanism 15 simple in structure, scientifically reasonable, and easy to manufacture.

[0030] Specifically, the front surface of the lock base 1 has a through hole extending into the slide groove 11. The screw connector 151 is a screw structure with a nut at its other end. One end of the screw connector 151 passes through the through hole and is screwed onto the push block 152. By continuously tightening the screw connector 151 until it is clamped onto the lock base 1, the push block 152 will always push out the locking member 153, ensuring that one end of the locking member 153 remains extended outside the groove of the slide groove 11. This prevents the telescopic locking mechanism 15 from loosening after being fitted into the pre-set installation hole in the door leaf, resulting in a more secure installation. By providing the through hole on the front surface of the lock base 1, the telescopic locking mechanism 15 can be easily released, facilitating the removal of the lock base 1 from the door or window.

[0031] To prevent the clamping member 153 from loosening and falling off, the clamping member 153 is provided with an oblong hole extending from one end to the other, and the length direction of the radial cross-section of the oblong hole is the same as the sliding direction of the clamping member 153. The slide groove 11 is also provided with a limiting pin that passes through the oblong hole. This design does not affect the movement of the clamping member 153, and also prevents the clamping member 153 from loosening and falling off, making it very practical and reliable.
