Description

Technical Field

[0001] The utility model relates to the technical field of locks, in particular to a rotary-open pop-up lock core and a door lock. Background Art

[0002] Mechanical locks are devices that can only be opened with a key. They have the functions of protection, management and even decoration, and are suitable for different occasions and needs. Some instrument or equipment cabinet doors are small in size and cannot be equipped with handles due to space constraints, especially instrument cabinets on trains. There are four main solutions in the prior art:

[0003] 1. Leaving the key on the lock cylinder when opening the door and using the key slightly tilted as a handle to open the door, this often causes the key or lock cylinder to deform, causing the key to slip off during the door opening process and the door cannot be opened, or causing the key or lock cylinder to be damaged and unable to open the door; in addition, train attendants carry multiple keys together and use them as handles to open the door, which is inconvenient;

[0004] 2. Use a flat, hard object to pry the door open between the door and the door frame. This will cause the door or door frame to deform or damage and make it more difficult to open the door.

[0005] 3. Use the attached Fig.16 The original lock core shown in the figure, when the lock is unlocked, the lock core partially pops out to be used as a door handle, but the original lock core has a large radial dimension, resulting in a large volume, which makes the space occupied too large, and the small space for structural optimization makes the lock core heavy, and the cabinet door is heavy and easily deformed, and the appearance is extremely inconsistent when used on a cabinet door with a smaller size;

[0006] 4. Installing a rebounder on the cabinet door makes it easier to open the cabinet door, but it will also increase the load-bearing capacity of the cabinet door and is more expensive, so it is not suitable for widespread application. Utility Model Content

DETAILED DESCRIPTION

[0057] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0058] See also Figure 1 , the embodiment of the utility model provides a rotary-open pop-up lock core, including a rotor structure and a fixed sleeve, the rotor structure is used to cooperate with the key and act on the unlocking structure 2 to realize the opening action, the fixed sleeve is used to install the lock core 1 on the door body 5, the fixed sleeve 12 includes a first end 1201 and a second end 1202 along the axial direction, when installed on the door body 5, when the door body 5 is closed, the first end 1201 is located on the outside of the door body 5, usually the first end 1201 is flush with the outer side of the door body 5 or is located near the outer side of the door body 5 (sometimes slightly concave on the outer side of the door body 5, sometimes slightly convex on the outer side of the door body 5) without affecting the outer space of the door body 5, the inner wall of the fixed sleeve 12 is provided with a limiting groove 124, the limiting groove 124 includes a third end 12401 and a fourth end 12402;

[0059] The rotor structure includes a first rotor assembly 11 and a second rotor assembly 13 that are axially slidably matched along the fixed sleeve 12. The first rotor assembly 11 is used to match with the key, and is used to connect with the second rotor assembly 13 to the unlocking structure 2. During the opening or locking process, the first rotor assembly 11 moves between the third end 12401 and the fourth end 12402 along the limiting groove 124, and the second rotor assembly 13 rotates back and forth along the circumferential direction of the fixed sleeve 12. When the key matches with the first rotor assembly 11 and an opening or locking action occurs, the first rotor assembly 11 drives the second rotor assembly 13 to rotate along the circumferential direction of the fixed sleeve 12, and at the same time, the first rotor assembly 11 moves between the third end 12401 and the fourth end 12402 under the action of the limiting groove 124.

[0060] In the locked state: the first rotor assembly 11 is located in the fixing sleeve 12, or the outer end surface of the first rotor assembly 11 is flush with the end surface of the first end 1201, or the outer end surface of the first rotor assembly 11 is convex from the end surface of the first end 1201 and close to the plane where the end surface of the first end 1201 is located, that is, in the locked state, the first rotor assembly 11 does not affect the outer space of the first end 1201, preferably located in the fixing sleeve 12 or the outer end surface of the first rotor assembly 11 is flush with the end surface of the first end 1201, the first rotor assembly 11 cooperates with the third end 12401, and the third end 12401 is used to limit the first rotor assembly 11 from opening by itself;

[0061] When in the open state: the outer end of the first rotor assembly 11 extends out of the first end 1201, that is, similar to the outer end of the first rotor assembly 11 popping out of the first end 1201 during the opening process, the extended portion can be used as a handle to open the door body 5 where the lock core 1 is located, the first rotor assembly 11 cooperates with the fourth end 12402, and relative sliding occurs between the first rotor assembly 11 and the second rotor assembly 13 during the extension process.

[0062] Through the limiting cooperation between the limiting groove 124 and the first rotor assembly 11 and the first rotor assembly 11 and the second rotor assembly 13 that slide with each other along the axial direction of the fixing sleeve 12, the outer end of the first rotor assembly 11 is extended out of the first end 1201 during the opening process, so that it can be used as a handle in the open state without the need for an additional ejector, thereby reducing costs. In the locked state, the outer end of the first rotor assembly 11 is retracted into the fixing sleeve 12 or close to the plane where the first end 1201 is located, so as to avoid affecting the outer space of the door body 5 when it is closed.

[0063] For the convenience of comparison with this embodiment, see the attached Fig.16 The original lock core 6 in the prior art includes an original fixed sleeve 66, an original rotating core 61, a sliding sleeve 62, an inner locking sleeve 63, an outer locking sleeve 64 and a second limiting pin 69. A second spring 65 is arranged between the inner end of the original rotating core 61 and the inner end of the inner locking sleeve 63. One end of the outer locking sleeve 64 is sleeved outside the inner locking sleeve 63, and a limiting protrusion 631 located outside the inner locking sleeve 63 cooperates with a limiting L groove 641 provided on the side wall of the outer locking sleeve 64. The outer end of the original rotating core 61 passes through one end of the sliding sleeve 62, and the outer end of the inner locking sleeve 63 passes through the other end of the outer locking sleeve 64. The sliding sleeve 62 and the outer locking sleeve 6 4 is fixedly connected by a second limiting pin 69, that is, the interior of the sliding sleeve 62 at least accommodates the inner end of the original rotating core 61, the inner end of the inner locking sleeve 63, and the second spring 65, and the sliding sleeve 62 and the outer locking sleeve 64 are fixedly connected as a whole by the second limiting pin 69, and the whole is slidably matched with the inner side wall of the original fixed sleeve 66 along the axial direction of the original fixed sleeve 66 through the second limiting pin 69. In the embodiment of the utility model, the lock core 1 includes a fixed sleeve 12 and a first rotor assembly 11 and a second rotor assembly 13 that slide with each other. Compared with the original lock core 6, the volume is smaller, see Fig.15 , the quality also decreases;

[0064] During the opening process, the original rotating core 61 drives the inner locking sleeve 63 to rotate, and the limiting protrusion 631 moves from one end to the other end along the limiting L groove 641. Under the action of the second spring 65, the original rotating core 61 drives the sliding sleeve 62, the second limiting pin 69 and the outer locking sleeve 64 to slide along the axial direction of the original fixed sleeve 66 and extend out of the corresponding end of the original fixed sleeve 66. In addition to the original rotating core 61 which serves as the rotor structure of the original lock core 6 (that is, it rotates relative to the original fixed sleeve 66 during the opening or locking process), the components that slide relative to the original fixed sleeve 66 along the axial direction also include the non-rotor structure sliding sleeve 62 and the outer locking sleeve 64. The structure is complex, and the volume of the components that slide relative to the original fixed sleeve 66 along the axial direction is large, the impact on the sliding part is large, and it is easy to cause damage to the components. Therefore, the requirements on the material of the components are high, and the quality is further increased.

[0065] See also Figure 1 , 3, 5, 6, in some preferred embodiments, the first rotor assembly 11 includes a rotating core 111, a rotating sleeve 112 and a first limiting pin 113;

[0066] The rotating core 111 includes a rotating core head 1113 arranged at one end of the axial direction. The rotating core head 1113 is used to cooperate with the key to realize the opening process. During the opening process, the key cooperates with the rotating core head 1113 to drive the rotating core 111 to rotate. Preferably, the key is a commonly used inner square or inner octagonal key in trains, and the corresponding rotating core head 1113 is a square head or an octagonal head.

[0067] One end of the rotating sleeve 112 is connected to the middle of the rotating core 111, and the other end is arranged around the outer side of the rotating core head 1113. The rotating sleeve 112 is added to the rotating core 111 to facilitate the use of a handle to apply force. In the open state, the end around the outer side of the rotating core head 1113 is used as a handle to open the door body where the lock core 1 is located;

[0068] The first limit pin 113 is inserted between the other axial end of the rotating core 111 and the second rotor assembly 13. The other end of the rotating core 111 and the second rotor assembly 13 slide in cooperation with the axial direction of the fixed sleeve 12. At least one axial end of the first limit pin 113 cooperates with the limit groove 124. Preferably, both axial ends of the first limit pin 113 cooperate with the limit groove 124. At this time, a limit groove 124 is correspondingly arranged on both sides of the side wall of the fixed sleeve 12.

[0069] The fixing sleeve 12 is cylindrical and hollow, see Figure 7 , 8The hollow part includes a telescopic groove 122 and a movable groove 123 along the axial direction. The inner diameter of the telescopic groove 122 is larger than the inner diameter of the movable groove 123. When in the locked state, the rotating sleeve 112 matches the telescopic groove 122, and the limiting groove 124 is arranged on the side wall of the movable groove 123. Preferably, the wall thickness of the movable groove 123 is greater than the wall thickness of the telescopic groove 122. The limiting groove 124 needs to be arranged in the movable groove 123. The larger wall thickness can ensure the structural strength of the limiting groove 124, while the inner wall of the telescopic groove 122 is smooth and not prone to damage caused by stress. The smaller wall thickness can achieve further weight reduction; the outer wall of the fixed sleeve 12 includes a door body connecting part 121 and an external threaded part 125. Preferably, the outer diameter of the door body connecting part 121 is not less than the outer diameter of the external threaded part 125. Usually, a through hole is arranged on the door body 5, and an internal thread is arranged at the through hole. The patterned disk 31 is used to install the lock core 1, the external threaded portion 125 is threadedly matched with the internal threaded disk 31, the door body connecting portion 121 matches the through hole on the door body 5, and further, the outer side of the telescopic groove 122 corresponds to the door body connecting portion 121, and the outer side of the movable groove 123 corresponds to the external threaded portion 125. The size of the through hole opened on the door body 5 can be relatively large, the hole opening is convenient and the weight of the door body 5 can be reduced. Therefore, the corresponding outer diameter at the door body connecting portion 121 can be relatively large, and the internal threaded disk 31 matched with the external threaded portion 125 usually needs to be additionally added to the door body 5, which is a weight-increasing item for the door body 5. Therefore, the relatively small external threaded portion 125 can be adapted to the smaller internal threaded disk 31 to achieve further weight reduction, and the larger wall thickness at the movable groove 123 can also ensure the structural strength of the threaded connection and ensure the service life of the lock core.

[0070] In some preferred embodiments, a second convex edge 126 is provided on the circumferential surface of the end of the door body connection portion 121 away from the external threaded portion 125, which is used to conceal the ugliness and facilitate the setting of a status mark 129, which is used to identify the open state and the locked state.

[0071] In some preferred embodiments, see Figure 1 , 9 , the rotating core 111 further includes:

[0072] The straight rod 1111 is arranged along the axis of the fixed sleeve 12, and the rotating core head 1113 is fixed at one axial end of the straight rod 1111. Preferably, the outer diameter of the straight rod 1111 is close to the outer diameter of the square head or the octagonal head. The volume of the main body of the first rotor assembly 11 is mainly determined by the radial size of the rotating core 111. The structure is simple, and the volume of the first rotor assembly 11 can be further reduced.

[0073] The insertion hole 1112 is provided at the other end of the straight rod 1111 in a direction perpendicular to the axis of the straight rod 1111, and the first stop pin 113 is inserted into the insertion hole 1112, which has a simple structure and a reasonable design;

[0074] And the first annular protrusion 1114 is arranged in the axial middle part of the straight rod 1111. The first annular protrusion 1114 is rotatably matched with the rotating sleeve 112. The first annular protrusion 1114 is rotatably connected with the rotating sleeve 112. When the first rotor assembly 11 moves back and forth along the axial direction of the fixed sleeve 12, direct contact between the core head 1113, the straight rod 1111 and the fixed sleeve 12 can be prevented or reduced, and the part of the core 111 extending out of the first end 1201, especially the core head 1113, can be protected in the open state, thereby improving the service life of the core 111.

[0075] Preferably, a first annular groove 1115 is circumferentially provided on the side of the first annular protrusion 1114, and a gasket 114 is arranged in the first annular groove 1115. The gasket 114 is rotatably matched with the rotating sleeve 112, and the gasket 114 is C-shaped, i.e., in an unsealed state, which is convenient for installation and can ensure the matching effect of the rotating support.

[0076] See also Figure 6 , 9 In some preferred embodiments, the rotating sleeve 112 includes a rotating sleeve body 1121 which is cylindrical and open at one end. The other end of the rotating sleeve body 1121 is sleeved on the outside of the first annular protrusion 1114 and rotatably cooperates with the first annular protrusion 1114. The open end of the rotating sleeve body 1121 is arranged on the circumferential outside of the rotating core head 1113 to form a key slot 1123. When the key cooperates with the rotating core head 1113, the key head is accommodated in the key slot 1123.

[0077] In some preferred embodiments, see Figure 6 , 9 A first protrusion 1122 is provided at the outer edge of the open end of the rotating sleeve body 1121 for convenient force application when used as a handle. Correspondingly, an adaption groove 127 corresponding to the first protrusion 1122 is provided at the end of the telescopic groove 122 away from the movable groove 123 .

[0078] In some preferred embodiments, a rubber ring 115 is provided between the outer circumferential surface of the rotating sleeve body 1121 and the side wall of the telescopic groove 122 to ensure the sealing of the interior of the lock core 1 and thereby increase the service life of the lock core 1.

[0079] In some preferred embodiments, see Figure 1 , 3, 5, 6, the second rotor assembly 13 includes a locking sleeve 133, one axial end of the locking sleeve 133 is slidably sleeved outside the rotating core 111, and the portion where the locking sleeve 133 and the rotating core 111 are slidably sleeved with each other is located in the fixed sleeve 12, the inner diameter of the main body of the second rotor assembly 13 depends on the outer diameter of the main body of the rotating core 111, that is, the inner diameter of the locking sleeve 133 can match the outer diameter of the straight rod 1111, the structure is simple and the volume is small, the other axial end of the locking sleeve 133 is used to connect the unlocking structure 2, the locking sleeve 133 and the second end 1202 are rotatably matched, preferably, the inner wall of the second end 1202 of the fixed sleeve 12 is provided with a transition portion 128, a rotating portion 1335 rotatably matched with the adapter portion 128 is provided on the lock sleeve 133, a first oblong hole 1333 matched with the first limit pin 113 is provided on the side wall of the lock sleeve 133, and the length direction of the first oblong hole 1333 extends along the axial direction of the lock sleeve 133; preferably, the lock sleeve 133 includes a lock sleeve body 1331, and a second mounting groove 1332 provided at one end of the lock sleeve body 1331, the second mounting groove 1332 is slidably sleeved outside the rotating core 111, that is, the mounting groove 1332 is slidably sleeved outside the straight rod 1111 and slidably matched with the straight rod 1111 along the axial direction;

[0080] During the opening or locking process, the first limit pin 113 moves back and forth along the length direction of the first oblong hole 1333. The first oblong hole 1333 limits the relative sliding between the first rotor assembly 11 and the second rotor assembly 13. At the same time, it can also be used to limit the extended position of the first rotor assembly 11. In the locked state: the first limit pin 113 is located at the end of the first oblong hole 1333 close to the second end 1202; in the open state: the first limit pin 113 is located at the end of the first oblong hole 1333 away from the second end 1202.

[0081] In some preferred embodiments, see Figure 1 , 3 , 5, 6, the rotor structure also includes a first spring 14, the first spring 14 is arranged between the ends of the rotating core 111 and the locking sleeve 133 that are close to each other, when in the open state, the first rotor assembly 11 is limited to the fourth end 12402 by the first spring 14, and when in the locked state, the limiting effect of the third end 12401 on the first rotor assembly 11 is strengthened, thereby simplifying the limiting structure; preferably, a cavity is formed between the locking sleeve 133 and the rotating core 111, the cavity includes the second mounting groove 1332, or the cavity includes the second mounting groove 1332 and the first mounting groove 1116 opened at the corresponding end of the rotating core 111 (when the locking sleeve 133 is slidably sleeved on the outside of the rotating core 111, the first mounting groove 1116 and the second mounting groove 1332 form a cavity), the first spring 14 is placed in the cavity, one end of the first spring 14 is against the locking sleeve 133, and the other end is against the rotating core 111.

[0082] In some preferred embodiments, see Figure 7 ,8 The limiting groove 124 is L-shaped, the vertical portion of the L-shape is parallel to the axial direction of the fixing sleeve 12, and the horizontal portion is along the circumferential direction of the fixing sleeve 12. The vertical portion is between the first groove wall 1241 and the fourth groove wall 1244 which are parallel to each other. In the open state, the first limiting pin 113 is located between the first groove wall 1241 and the fourth groove wall 1244, and the horizontal portion is between the first groove wall 1241, the second groove wall 1242, and the third groove wall 1243. In the locked state, the first limiting pin 113 is located in the horizontal portion and is axially limited by the third groove wall 1243 and circumferentially limited by the second groove wall 1242.

[0083] In the locked state, under the action of the first spring 14, the end of the first limiting pin 113 is pressed against the third groove wall 1243 at the third end 12401 close to the second groove wall 1242 to limit the rotor structure.

[0084] During the opening process, the rotating core 111 rotates, driving the first limiting pin 113 to approach the first groove wall 1241 along the third groove wall 1243. When the first limiting pin 113 is located between the first groove wall 1241 and the fourth groove wall 1244, it slides along the first groove wall 1241 away from the second end 1202 under the action of the first spring 14, so that the rotating core 111 and the rotating sleeve 112 are "popped out".

[0085] In the open state, the rotating core 111 and the rotating sleeve 112 are limited by the first spring 14, and then the first limiting pin 113 is limited at the fourth end 12402 between the first groove wall 1241 and the fourth groove wall 1244, and the first limiting pin 113 is limited by the fourth groove wall 1244 to prevent the first rotor assembly 11 from rotating along the circumferential direction of the fixed sleeve 12, thereby preventing the lock tongue in the lock 4 from resetting;

[0086] During the locking process, the key can be used in conjunction with the core head 1113 to apply axial pressure to cause the first limit pin 113 to return along the first groove wall 1241 and the fourth groove wall 1244 to between the first groove wall 1241 and the second groove wall 1242, and then the core 111 can be rotated to reset the first limit pin 113. The rotating sleeve 112 can also be reset in the axial direction by pressing. At this time, the first limit pin 113 returns to between the first groove wall 1241 and the second groove wall 1242, and the first limit pin 113 is disengaged from the circumferential limit of the fourth groove wall 1244. During the process of resetting the lock tongue in the lock 4, the first limit pin 113 is driven to rotate circumferentially. At this time, stop applying force to the rotating sleeve 112 to complete the locking process, which is convenient to operate.

[0087] Furthermore, the L-shaped vertical portion penetrates the side wall of the fixing sleeve 12, and the penetrated portion facilitates the disassembly and assembly of the rotor structure. During the opening process or in the open state, the L-shaped vertical portion guides the axial sliding of the first rotor assembly 11, and the sliding position of the first rotor assembly 11 is limited by the first oblong hole 1333.
