Description

Technical Field

[0001] This utility model relates to the field of sliding door technology, and in particular to a sliding door. Background Technology

[0002] Interior design strives for a cohesive and unified aesthetic, aiming to minimize elements that disrupt the overall style. This has led to the development of optimized door locks designed to accommodate doors with concealed designs.

[0003] Current door locks have standard lengths, and doors also have standard thicknesses. The length of the lock cylinder is usually based on the thickness of the door. When this traditional lock cylinder is installed on the door, one or both ends will protrude from the surface of the door panel.

[0004] A concealed sliding door is a type of door that is pulled out when closed and pushed into the wall when opened. The opening width of the door panel is slightly larger than the thickness of the door panel. Existing door locks installed on concealed sliding doors are longer than the opening width of the door panel, resulting in a wider opening and a poorer visual concealment effect. Therefore, it is necessary to develop a sliding door in which the thickness of the door lock and the door panel are approximately the same.

[0005] This lock cylinder is shorter than existing door locks, making it suitable for concealed sliding doors without interfering with openings in the door panel. Utility Model Content

[0006] To address the aforementioned shortcomings, the purpose of this utility model is to propose a door lock that optimizes the lock cylinder body and lock cylinder drive shaft, thereby reducing the length of the lock cylinder body and lock cylinder drive shaft, thus optimizing the overall length of the lock cylinder.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] A sliding door includes a door panel and a door lock. The side end of the door panel has a receiving cavity for accommodating the door lock, and the door lock is accommodated in the door lock receiving cavity.

[0009] A key opening is provided at the position corresponding to the door panel and the inner lock cylinder, extending outward from the door lock receiving cavity, and the inner lock cylinder is received in the key opening;

[0010] A handle opening is provided on the door panel corresponding to the handle, extending outward from the door lock cavity. A handle receiving position is recessed on the door panel surface corresponding to the handle opening. The handle is located in the handle receiving position, and the handle's pivot is installed on the lock cylinder through the handle opening.

[0011] Preferably, it also includes a concealed handle, wherein the concealed handle is installed on the inside of the door panel and is correspondingly installed at the handle opening position, and the pivot of the handle passes through the corresponding concealed handle and is installed in the lock cylinder; the handle is accommodated in the concealed handle;

[0012] The concealed handle on the outside of the door panel is installed at the key opening position, and the inner lock cylinder passes through the key opening into the corresponding concealed handle.

[0013] Preferably, the lock cylinder includes a lock cylinder base and an inner lock cylinder;

[0014] The lock cylinder base has a through hole along its length. The right end of the inner lock cylinder extends into the left end of the through hole. The left end of the inner lock cylinder corresponds to the left end extending into the through hole. The end face of the left end of the inner lock cylinder is provided with a key slot, which is distributed along the length of the inner lock cylinder.

[0015] Preferably, it also includes a lock cylinder cam and an inner lock cylinder rotating shaft;

[0016] The lock cylinder base has a notch that divides the through hole into two sections. The lock cylinder cam is located in the notch. The end face of the lock cylinder cam has a guide through hole. The right end of the inner lock cylinder rotating shaft extends into the right end of the guide through hole through the through hole. The left end of the inner lock cylinder rotating shaft extends into the left end of the guide through hole and engages with the inner lock cylinder rotating shaft. The handle is fixedly installed on the right end of the inner lock cylinder rotating shaft.

[0017] The left end face of the inner lock cylinder rotating shaft is provided with a groove, and the two side walls of the groove respectively penetrate the outer side of the inner lock cylinder rotating shaft. The guide through hole is provided with an annular sleeve, and the right end of the guide through hole is provided with a guide protrusion. The groove and the guide protrusion are in a transmission cooperation, and the left end face of the inner lock cylinder rotating shaft abuts against the right end face of the annular sleeve.

[0018] Preferably, the inner lock cylinder rotating shaft has a cylindrical sliding cavity along the center line, and a circular sliding hole is opened at the center of the lock cylinder cam corresponding to the sliding cavity. A sliding docking cavity is opened at the right end of the inner lock cylinder to the left, and the sliding hole corresponds to the sliding docking cavity. The sliding cavity, sliding hole and sliding docking cavity constitute a sliding channel, and the clutch sliding cylinder is slidably fitted into the sliding channel.

[0019] The left end of the clutch sliding cylinder is provided with a key receiving groove. The key receiving groove is opened on the side walls on both sides of the clutch sliding cylinder. The key receiving groove extends from the inside of the clutch sliding cylinder to the outer side and corresponds to the key slot.

[0020] The upper side of the clutch sliding cylinder is provided with a clutch protrusion, which is located in the front left section of the clutch sliding cylinder. The sliding hole is provided with a clutch groove adapted to the clutch protrusion. A spring is provided at the right end of the clutch sliding cylinder. One end of the spring is pressed against the closed end of the sliding cavity, and the other end of the spring is pressed against the left end of the clutch sliding cylinder.

[0021] The stroke of the sliding docking cavity is consistent with the length of the key receiving groove and the length of the clutch protrusion. The sliding hole is located on the right side of the sliding docking cavity of the clutch groove. In the natural state, the clutch groove does not form a transmission engagement with the clutch protrusion.

[0022] In the transmission state, the key is inserted into the clutch sliding cylinder through the key slot, and the end of the key is accommodated in the key receiving groove of the clutch sliding cylinder. The key pushes the clutch sliding cylinder to slide to the right, and the clutch protrusion slides into the clutch groove to form a transmission assembly.

[0037] The components include: door panel 100, door lock 200, lock cylinder 210, lock cylinder base 211, inner lock cylinder 212, through hole 213, key slot 214, handle 215, lock cylinder cam 216, inner lock cylinder rotating shaft 217, notch 218, slot 219, guide through hole 2110, ring sleeve 2111, guide protrusion 2112, sliding cavity 221, sliding hole 222, sliding docking cavity 223, clutch sliding cylinder 230, key receiving slot 231, clutch protrusion 232, clutch groove 233, spring 234, baffle 235, guide rod 236, outer baffle 237, concealed handle 300, and rotating cover 400. Detailed Implementation

[0038] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0039] like Figure 1 As shown, a sliding door includes a door panel 100 and a door lock 200. The side end of the door panel 100 has a receiving cavity for accommodating the door lock 200, and the door lock 200 is accommodated in the door lock receiving cavity. One end of the lock cylinder 210 of the door lock 200 is an inner lock cylinder 212, and the other end is a handle 215.

[0040] A key opening is provided on the door panel 100 at the position corresponding to the inner lock cylinder 212, extending outward from the door lock receiving cavity, and the inner lock cylinder 212 is received in the key opening;

[0041] A handle opening is provided on the door panel 100 from the door lock receiving cavity outward at the position corresponding to the handle 215. A handle receiving position is provided in the recess of the door panel surface corresponding to the handle opening. The handle 215 is located in the handle receiving position. The rotating shaft of the handle 215 is installed on the lock cylinder 210 through the handle opening.

[0042] The solution sets the length of the lock cylinder and the lock handle within the thickness of the door panel, reducing the interference caused by the sliding door handle and lock cylinder protruding from the door panel surface. In actual use, reducing the protrusion on one side of the door panel reduces the gap between the side corresponding to the opening of the door panel receiving space and the door panel, thus achieving a better effect. If the protrusions on both sides of the door panel are reduced, when the sliding door is retracted into the door panel receiving space, the smaller gap between the two sides of the door panel and the door panel receiving space will achieve a better concealment effect.

[0043] like Figure 2-3 As shown, it also includes a concealed handle 300. The concealed handle 300, which is concealed on the inside of the door panel, is installed at the corresponding handle opening position. The pivot of the handle 215 passes through the corresponding concealed handle and is installed in the lock cylinder 210. The handle 215 is accommodated in the concealed handle 300.

[0044] The concealed handle 300 on the outside of the door panel is installed at the key opening position, and the inner lock cylinder 212 passes through the key opening into the corresponding concealed handle 300.

[0045] The proposed solution involves creating a recess in the door panel and concealing a handle 300 within it. This ensures that both the handle 215 and one end of the keyhole of the inner lock cylinder 212 are within the concealed handle 300, thus adding a door panel handle without exceeding the thickness of the door panel. In the alternative solution without using the concealed handle 300, only one keyhole is exposed on the side of the door panel corresponding to the inner lock cylinder 212, providing a better concealment effect.

[0046] like Figure 4 As shown, the lock cylinder 210 includes a lock cylinder base 211 and an inner lock cylinder 212;

[0047] The lock cylinder base 211 has a through hole 213 along its length. The right end of the inner lock cylinder 212 extends into the left end of the through hole 213. The left end of the inner lock cylinder 212 corresponds to the left end extending into the through hole 213. The end face of the left end of the inner lock cylinder 212 is provided with a key slot 214. The key slot 214 is distributed along the length of the inner lock cylinder 212.

[0048] The lock cylinder used in the solution is a key-rotation lock cylinder. The inner lock cylinder 212 rotates relative to the lock cylinder base 211, driving the structure inside the lock cylinder base 211 to achieve locking and releasing.

[0049] like Figure 5As shown, it also includes a lock cylinder cam 216 and an inner lock cylinder rotating shaft 217;

[0050] The lock cylinder base 211 has a notch 218 that divides the through hole 213 into two sections. The lock cylinder cam 216 is located in the notch 218. The end face of the lock cylinder cam 216 has a guide through hole 2110. The inner lock cylinder rotating shaft 217 extends into the right end of the guide through hole 210 through the right end of the through hole 213. The left end of the inner lock cylinder rotating shaft 217 extends into the left end of the guide through hole 2110 and engages with the inner lock cylinder rotating shaft 217. The handle 215 is fixedly installed on the right end of the inner lock cylinder rotating shaft 217.

[0051] The left end face of the inner lock cylinder rotating shaft 217 is provided with a groove 219. The two side walls of the groove 219 respectively penetrate the outer side of the inner lock cylinder rotating shaft 217. The guide through hole 2110 is provided with an annular sleeve 2111. The right end of the guide through hole 2110 is provided with a guide protrusion 2112. The groove 219 and the guide protrusion 2112 are in a transmission engagement. The left end face of the inner lock cylinder rotating shaft 217 abuts against the right end face of the annular sleeve 2111.

[0052] The lock cylinder cam 216 is the mechanism that actuates the inner bolt of the door lock 200. When unlocking, the purpose of rotating the inner lock cylinder 212 and the inner lock cylinder rotating shaft 217 is to drive the lock cylinder cam 216 to rotate by a certain angle. When opening the door from the outside, the key is used to drive the inner lock cylinder 212 to rotate, which in turn drives the lock cylinder cam 216 to rotate. When opening the door from the inside, the handle 215 is used to drive the inner lock cylinder rotating shaft 217 to drive the lock cylinder cam 216 to rotate. When the inner lock cylinder rotating shaft 217 rotates, the slot 219 drives the lock cylinder cam 216 to rotate synchronously through the guide protrusion 2112 and the guide through hole 2110. The left end face of the inner lock cylinder rotating shaft 217 abuts against the right end face of the annular sleeve 2111, which can constrain the degree of freedom of the lock cylinder cam 216.

[0053] like Figure 6 and Figure 8 As shown, the inner lock cylinder rotating shaft 217 has a cylindrical sliding cavity 221 along its center line. The center of the lock cylinder cam 216 has a circular sliding hole 222 corresponding to the sliding cavity 221. The right end of the inner lock cylinder 212 has a sliding docking cavity 223 extending to the left, and the sliding hole 222 corresponds to the sliding docking cavity 223. The sliding cavity 221, the sliding hole 222, and the sliding docking cavity 223 constitute a sliding channel, and the clutch sliding cylinder 230 is slidably fitted into the sliding channel.

[0054] The clutch sliding cylinder 230 is provided with a key receiving groove 231 at its left end. The key receiving groove 231 is opened on the side walls on both sides of the clutch sliding cylinder 230. The key receiving groove 231 extends from the inside of the clutch sliding cylinder 230 to the outer side and corresponds to the key slot 214.

[0055] The upper side of the clutch sliding cylinder 230 is provided with a clutch protrusion 232, which is located in the front left section of the clutch sliding cylinder 230. The sliding hole 222 is provided with a clutch groove 233 adapted to the clutch protrusion 232. The right end of the clutch sliding cylinder 230 is provided with a spring 234, one end of which abuts against the closed end of the sliding cavity 221, and the other end of which abuts against the left end of the clutch sliding cylinder 230.

[0056] The stroke of the sliding docking cavity 223 is consistent with the length of the key receiving groove 231 and the length of the clutch protrusion 232. The sliding hole 222 is located on the right side of the sliding docking cavity 223 of the clutch groove 233. In the natural state, the clutch groove 233 does not form a transmission engagement with the clutch protrusion 232.

[0057] In the transmission state, the key is inserted into the clutch sliding cylinder 230 through the key slot, and the end of the key is accommodated in the key receiving groove 231 of the clutch sliding cylinder 230. The key pushes the clutch sliding cylinder 230 to slide to the right, and the clutch protrusion 232 slides into the clutch groove 233 to form a transmission assembly.

[0058] The sliding channel formed by the sliding cavity 221, the sliding hole 222, and the sliding docking cavity 223 provides sliding space for the clutch sliding cylinder 230. When the key is used to open the lock, the key head is inserted into the key receiving groove 231 through the inner lock cylinder 212, and the key head and the inner lock cylinder 212 form a transmission engagement. However, at this time, the clutch protrusion 232 of the clutch sliding cylinder 230 needs to slide further to the right into the clutch groove 233 so that the clutch sliding cylinder 230 can rotate synchronously when the key is turned. Then, the clutch sliding cylinder 230 drives the lock cylinder cam 216 with the clutch groove 233 to rotate, thereby realizing the unlocking. After the key is reset and pulled out, the clutch sliding cylinder 230 returns to its original position. At this time, when the handle 215 is used to drive the inner lock cylinder rotating shaft 217, the clutch sliding cylinder 230 will not rotate synchronously with the rotation of the lock cylinder cam 216.

[0059] like Figure 7 and Figure 8 As shown, the clutch sliding cylinder 230 is cylindrical, with an opening at the left end. A baffle 235 is slidably disposed inside the circular cavity. A guide rod 236 is provided to the right of the baffle 235. The guide rod is installed on the outer baffle 237 through a guide rod hole opened at the right end of the clutch sliding cylinder 230. The outer baffle is slidably disposed in the sliding cavity 221.

[0060] One end of the spring 234 abuts against the outer baffle 237, and the other end abuts against the closed end of the sliding cavity 221.

[0061] In its natural state, the baffle 235 rests against the right end of the inner lock cylinder 212 located inside the lock cylinder base 211. The baffle 235 is pushed open only after the key is inserted into the key receiving slot 231, thereby sealing and protecting the lock cylinder's engagement and disengagement structure.

[0062] Furthermore, the length of the inner lock cylinder rotating shaft 217 does not exceed the lock cylinder base 211.

[0063] Since the handle 215 of the lock cylinder is directly installed with the inner lock cylinder rotating shaft 217, there is no additional shaft to increase the length, and the length of the inner lock cylinder rotating shaft is also limited to the same length as the lock cylinder base 211. Compared with the traditional lock cylinder, the length of the lock cylinder proposed in this solution is reduced. Therefore, this lock cylinder can be used for thinner bus doors and concealed pocket doors.

[0064] In addition, the inner lock cylinder 212 is a leaf lock cylinder.

[0065] In addition, a rotating cover 400 is installed on the key opening, which is used to cover the inner lock cylinder 212 inside the key opening.

[0066] Because of the rotating cover 400, visually, the outside of the door only has a small keyhole (16mm in diameter) with the rotating cover. After opening the rotating cover, the key passes through the small keyhole and is directly inserted into the lock cylinder hidden inside the door panel, activating the key's combination teeth to lock / unlock. When the door is not being opened with a key, the rotating cover 400 can be rotated to cover the inner lock cylinder 212, effectively concealing the lock cylinder. The lock cylinder is not obviously exposed on the door, which is somewhat deceptive.

[0067] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
