Description

Technical Field

[0001] The utility model relates to the field of door locks, in particular to a lock core assembly convenient for assembly. Background Art

[0002] The lock tongue is a component that directly plays a locking role in the lock, and is the ultimate executor of the entire door lock system.

[0003] At present, existing magnetic lock bodies all adopt the principle of attracting each other with opposite magnetic poles of magnets to realize the contraction of the lock core. Therefore, generally, a magnet is arranged on the lock tongue, and a magnet of another magnetic pole is arranged on the housing of the lock body. So, by turning the lock body knob, the push lock block can be pushed to drive the movement of the lock tongue magnet head to achieve locking. The Chinese utility model patent with the publication number CN221194629U discloses a stable lock core structure for a flat door, including: a housing, including a sliding channel and an outer gasket, the outer gasket is connected to the housing through an extension surface, the extension surface is provided with a fitting groove, and the sliding channel is provided with a positioning groove and a knob hole; a lock core assembly, located in the sliding channel, including a push block, a knob and a lock tongue, the push block consists of a connecting head and extension wings, the lock tongue wraps the connecting head and includes a magnetic block, and the knob is arranged between the extension wings; a tongue sleeve, located in the fitting groove and nested on the lock core assembly. The utility model provides a stable lock core structure for a flat door, providing users with a lock core for a flat door with a compact structure, accurate inward and outward movement of the locking magnet head without movement jitter and position deviation, and capable of protecting the magnetic magnet inside the lock tongue from direct external collision and wear.

[0004] For the above technical solution, the actual assembly process of the lock core structure is divided into the following steps: 1. Install the spring on the connecting head, and then usually connect the connecting head and the extension wings at both ends into the lock tongue, and then tighten the bolts to fix the connecting head and the extension wings at both ends in the lock tongue to achieve linkage, thus completing the assembly of the lock core assembly; 2. Put the assembled lock core assembly into the housing, at the same time assemble the driving knob and install the tongue sleeve to complete the assembly of the lock core structure; however, when assembling the lock core assembly with the existing structure, the side edges of the extension wings on both sides are arranged on both sides of the connecting head (for example, as shown in Figure 4 at this time, the extension wings are positioned by convex columns), which causes the worker to need to press the extension wings on both sides with two fingers at the same time and then send them into the lock tongue. Since the position held by the fingers is also the part that needs to be inserted into the lock tongue, the worker can only insert a part little by little and then release it during assembly, which greatly affects the assembly efficiency. At the same time, after the connecting head and the extension wings on both sides are completely inserted, the worker still needs to connect the connecting head and the lock tongue with screws, and then fix the connecting head and the extension wings on both sides in the lock tongue to complete the assembly of the lock core assembly. However, this screw connection method not only affects the assembly efficiency, but also easily causes the connecting head to come out before the screws are inserted, and the worker needs to always fix the lock tongue, and the assembly process is time-consuming and laborious. Summary of the Invention

[0005] The technical problem to be solved by the utility model is to provide a lock core assembly convenient for assembly in view of the above-mentioned deficiencies of the prior art.

[0006] To achieve the above object, the utility model provides the following technical solution: A lock core assembly convenient for assembly, including a lock tongue, a connecting head, extending wings arranged on both sides of the connecting head, and a fixing device for fixing the connecting head and the extending wings on both sides in the lock tongue. Slots for inserting the ends of the extending wings are provided on both sides of the connecting head. Stopping blocks for preventing the extending wings from detaching from the connecting head are arranged outside the connecting head corresponding to the slots. A positioning mechanism for restricting the axial movement of the extending wings relative to the connecting head is arranged between the connecting head and the extending wings on both sides.

[0007] With the above technical solution, during assembly, the ends of the extending wings are inserted into the slots of the connecting head. By using the positioning mechanism, the axial movement between the extending wings and the connecting head is restricted. At the same time, the setting of the stopping blocks outside the slots also prevents the extending wings at this end from moving in opposite directions. That is, at this time, the worker only needs to press the two extending wings at the other end with two fingers and apply force towards each other, so that the extending wing at one end of the slot uses the positioning mechanism as a fulcrum to output an outward-opening acting force, and this acting force is applied to the stopping block to connect the connecting head and the extending wings on both sides. At this time, the worker only needs to apply pressure at the end to lift the connecting head and insert it into the cavity of the lock tongue, and then complete the assembly through the fixing device. And when inserting into the lock tongue, the worker does not need to hold the connecting head with fingers during assembly, and the connecting head can be stably fixed with the extending wings on both sides, thereby realizing the rapid assembly of the lock core assembly, simplifying the assembly process, improving the assembly efficiency, and preventing the extending wings from detaching during the assembly process.

[0008] The above-mentioned lock core assembly convenient for assembly can be further set as follows: The positioning mechanism includes a positioning convex block protruding outward or a positioning groove recessed inward on the outer wall of the connecting head, and a positioning groove or a positioning convex block arranged at the extending wing and cooperating with the positioning convex block or the positioning groove for clamping. When the extending wing is inserted into the slot, the positioning groove and the positioning convex block are clamped.

[0009] With the above technical solution, the axial movement between the extending wings and the connecting head is restricted by clamping and fixing the positioning convex block or the positioning groove with the corresponding structure on the extending wing, and the positioning clamping and subsequent stable assembly are completed.

[0010] The above-mentioned lock core assembly convenient for assembly can be further set as follows: There is an obliquely arranged oblique slideway between the positioning groove or the positioning convex block at the connecting head and the slot, and a bent portion corresponding to the oblique slideway is arranged at one end of the extending wing inserted into the slot.

[0011] With the above technical solution, an inclined slideway is provided between the positioning structure of the connecting head and the slot. The extension wing is inserted along the inclined slideway, and the bending part corresponds to the inclined slideway, realizing self-guided insertion. Cooperating with the bending part at the end of the extension wing, smooth insertion is achieved, so that the extension wing that has completed the inclined insertion can have a certain anti-loosening characteristic. At the same time, due to the setting of the inclined slideway, the slot is misaligned and arranged at the inner position relative to the positioning convex block, so that the stop block does not need to protrude outwards, and remains on the same axis as the outer wall of the installed extension wing, making it not easy to loosen after being fixed to the locking tongue subsequently, improving the accuracy and convenience of assembly, and reducing manual adjustment during assembly.

[0012] The above-mentioned lock core assembly convenient for assembly can be further set as: an insertion port or an insertion block is provided at the slot, and an insertion block or an insertion port for cooperating with the insertion port or the insertion block is provided at the end of the extension wing.

[0013] With the above technical solution, an insertion port or an insertion block is respectively provided at the slot and the end of the extension wing to realize the cooperating insertion between the two. For example, the insertion block at the end of the extension wing is inserted into the insertion port in the slot to complete the fixation, guiding and positioning during the end insertion, and at the same time, the left and right limits are applied to its end, so that the positioning convex block can be set into different shapes (such as circular, oval), providing additional fixing methods, increasing the stability of the component and the reliability of assembly.

[0014] The above-mentioned lock core assembly convenient for assembly can be further set as: the slot is arranged at the middle position on both sides of the connecting head, so that a fulcrum part for the extension wing part to abut against is formed between the slot and the outer wall of the connecting head. The positioning convex block or the positioning groove is arranged on the fulcrum part, and an abutting part is provided at the extension wing corresponding to the fulcrum part. When the extension wing is inserted into the slot, the abutting part abuts against the fulcrum part, and the positioning convex block is inserted into the positioning groove.

[0015] With the above technical solution, slots are arranged in the middle of both sides of the connecting head, so that the part of the connecting head with the positioning convex block or the positioning groove forms a fulcrum part. Cooperating with the positioning structure and the abutting part of the extension wing, stable assembly is realized. In this way, when the extension wing is inserted into the slot, the abutting part and the fulcrum part have a large area of abutting parts. In this way, when the worker assembles, after pressing the end of the extension wing, this fulcrum part can be used as the fulcrum of the lever, so that the worker can apply a small force to the connecting head through the lever principle for stable assembly.

[0016] The above-mentioned lock core assembly convenient for assembly can be further set as: one end of the extension wing away from the bending part has a linkage part. A limiting stop part bent towards the end away from the connecting head is provided between the abutting part and the linkage part, and the length from the linkage part to the fulcrum part is greater than the length from the fulcrum part to the bending part.

[0017] With the above technical solution, a linkage part is provided at one end of the extended wing away from the bending part, enabling the linkage part to control the lock tongue through a later-assembled knob. The length from the linkage part to the fulcrum part is greater than the length from the fulcrum part to the bending part, optimizing the mechanical structure, enabling workers to apply a relatively small force to the connection head through the lever principle, enhancing the assembly stability of the lock core assembly, reducing shaking or displacement during the process. At the same time, the bent limit stop part, that is, the space between the enlarged two-sided extended wings, improves the subsequent assembly space, facilitates the lock core assembly, and can prevent the excessive movement of the extended wings during subsequent use, maintaining the stability of the lock core assembly.

[0018] The above-mentioned lock core assembly convenient for assembly can be further set as: the fixing device includes a plurality of grooves or buckles provided on the lock tongue and buckles or grooves provided on the connection head corresponding to and engaging with the grooves or buckles.

[0019] With the above technical solution, using the groove or buckle as the fixing device realizes the rapid fixation of the connection head and the lock tongue, simplifies the fixing process, and improves the assembly speed and the fixing stability of the component.

[0020] The above-mentioned lock core assembly convenient for assembly can be further set as: two grooves are provided at both ends of the lock tongue corresponding to the connection head, buckles cooperating with the grooves are provided at both ends of the connection head, and a guiding buckle surface that gradually becomes higher along the insertion direction of the connection head is provided at one end of the buckle facing the lock tongue.

[0021] With the above technical solution, by providing the guiding buckle surface, when the connection head is inserted into the lock tongue, it can be guided by the guiding buckle surface and then slide into the buckle, improving the smoothness during assembly and the assembly efficiency.

[0022] The above-mentioned lock core assembly convenient for assembly can be further set as: the connection head further includes a magnetic block, the magnetic block is fixedly arranged at the end of the connection head, a plurality of buffer holes are provided on the lock tongue corresponding to the magnetic block, a plurality of buffer blocks corresponding to the buffer holes are provided on the magnetic block, and after the buffer blocks pass through the buffer holes, part of them extends out of the lock tongue surface.

[0023] With the above technical solution, a magnetic block is provided at the end of the connection head, enabling it to be used as the lock core of a magnetic lock. Through the setting of the buffer holes and buffer blocks, when the magnetic lock works, it can buffer when attracting to another place, reducing impact and wear, extending the service life, and making the locking process quieter.

[0024] The beneficial effects of the present utility model are:

[0025] 1. Quick assembly: Through the design of slots and positioning structures, axial movement is restricted, the stability of components is increased, the assembly process of the connector and the extension wing is simplified. The design of the inclined slideway and the bending part realizes self-guided insertion, has certain anti-loosening characteristics, improves the reliability of the components, improves the assembly efficiency, enables workers not to continuously hold the connector part during assembly, but only need to apply pressure at the end to lift the connector and insert the locking tongue, which simplifies the operation. At the same time, the length from the linkage part to the fulcrum part of the extension wing is greater than the length from the fulcrum part to the bending part, optimizing the mechanical structure and reducing shaking or displacement.

[0026] 2. The buffer block on the magnet block extends out of the locking tongue surface after passing through the buffer hole, providing buffering during work, reducing impact and wear, and reducing the noise during locking.

[0027] 3. Using a card slot and a buckle as a fixing device simplifies the fixing process of the connector and the locking tongue, eliminates the need for screws for assembly, and enables rapid assembly.

Slots 21 for inserting the ends of the extension wings 3 are provided on both sides of the connecting head 2. Stop blocks 22 for preventing the extension wings 3 from detaching from the connecting head 2 are provided on the outside of the connecting head 2 corresponding to the slots 21. A positioning mechanism for restricting the axial movement of the extension wings 3 relative to the connecting head 2 is provided between the connecting head 2 and the extension wings 3 on both sides. The extension wings 3 have a bent portion 31, an abutting portion 32, a linkage portion 34, and a limiting stop portion 33 provided between the abutting portion 32 and the linkage portion 34. The positioning mechanism includes a positioning convex block 231 protruding outward on the outer wall of the connecting head 2 and a positioning groove 321 provided at the abutting portion 32 and cooperating with the positioning convex block 231 for clamping. When the extension wings 3 are inserted into the slots 21, the positioning groove 321 is clamped with the positioning convex block 231. An inclined slideway 211 obliquely arranged corresponding to the bent portion 31 is provided between the positioning convex block 231 and the slots 21 at the connecting head 2. An insertion block 212 is provided in the middle of the slots 21, and a socket 311 for cooperating with the insertion block 212 for insertion is provided on the bent portion 31. The slots 21 are arranged between the magnetic block 4 and the positioning convex block 231, so that a fulcrum portion 32 for the partial abutment of the extension wings 2 is formed between the slots 21 and the outer wall of the connecting head 2. The positioning convex block 231 is arranged on the fulcrum portion 23, and an abutting portion 32 is provided on the extension wings 3 corresponding to the fulcrum portion 23. When the extension wings 3 are inserted into the slots 21, the abutting portion 32 abuts against the fulcrum portion 23, and the positioning convex block 231 is inserted into the positioning groove 321.

[0034] As Figure 2 shown, one end of the extension wing 3 far from the bent portion 31 has a linkage portion 34. A limiting stop portion 33 bent towards the end far from the connecting head 2 is provided between the abutting portion 32 and the linkage portion 34. The length from the linkage portion 34 to the fulcrum portion 32 is a, and the length from the fulcrum portion 32 to the bent portion 31 is b, and a > b, thereby realizing a labor-saving lever.

[0035] As Figure 1 、 Figure 2 shown, the fixing device includes a plurality of card slots 11 provided on the lock tongue 1 and a buckle 20 provided on the connecting head 2 and corresponding to the card slots 11 for buckling. A guiding buckle surface 201 that gradually becomes higher along the insertion direction of the connecting head 2 is provided at one end of the buckle 20 facing the lock tongue 1. When the connecting head 2 is inserted into the lock tongue 1, the buckle 20 will be quickly inserted into the card slot 11 along the guiding buckle surface 201, directly completing the assembly.

[0036] As Figures 1 - 3As shown, the magnetic block 4 is fixedly arranged at the end of the adapter 2. A plurality of buffer holes 10 are formed in the lock tongue 1 corresponding to the magnetic block 4. A plurality of buffer blocks 41 corresponding to the buffer holes 10 are arranged on the magnetic block 4. After the buffer blocks 41 pass through the buffer holes 10, part of them extends out of the surface of the lock tongue 1. When the lock core assembly of the present utility model is used on the magnetic lock, during its closing process, the lock tongue 1 will be sucked out and inserted into the lock bolt to lock. At this time, the buffer blocks 41 will abut first, reducing the noise caused by the impact during the sudden magnetic attraction process and realizing a quiet door closing.

[0037] As Figures 1 - 3 As shown, when assembling the lock core assembly of the present utility model, the user first inserts the socket 311 of the extension wing 3 into the insert block 212 of the slot 21 of the adapter 2. During this process, the bending part 31 on the extension wing 3 should be aligned with the inclined slideway 211 in the slot 21 to achieve self-guided insertion. At the same time, the positioning groove 321 on the extension wing 3 is engaged with the positioning convex block 231 on the adapter 2 to achieve axial positioning. At this time, the worker only needs to hold the linkage part 34 at the end with two fingers of one hand and apply pressure towards each other. The length from the linkage part 34 to the fulcrum part 32 should be greater than the length from the fulcrum part 32 to the bending part 31, forming a labor-saving lever structure, and can easily and stably lift the adapter 2. At this time, a spring is sleeved on the spring column 24, and then it is aligned and inserted into the lock tongue 2. The buckle 20 will slide along the guiding buckle surface 201 and quickly insert into the card slot 11 to achieve quick buckling, thereby completing the assembly of the lock core assembly. The whole process is stable, convenient and labor-saving during the installation process, and can quickly increase the assembly efficiency.
