Description

Technical Field

[0001] This utility model relates to a lock. Background Technology

[0002] Locks are commonly found on the market and are primarily used for sealing or theft prevention. Common locks include door locks and car locks. A typical car lock includes: 1. a lock body to prevent prying or sawing after locking; 2. a bolt to control the locking mechanism; and 3. a lock cylinder to move the bolt against the lock body, thus controlling the locking and unlocking of the car lock. The movement of the lock cylinder is generally controlled by a key.

[0003] In existing car locks, the rotation of the lock cylinder typically causes the latch (the hook at the rear of the cylinder) to rotate simultaneously, moving it into a groove in the lock body. However, in practice, the lock cylinder is often vertically oriented, meaning the latch at the rear of the cylinder is aligned with the lock body. This means the latch and the lock body are in the same direction, resulting in the lock being locked when the latch is engaged. If a car lock with this design is pulled in the opposite direction after being locked, there is a chance it will break, forcibly releasing the lock and causing damage. Summary of the Invention

[0004] In view of the above shortcomings, this utility model provides a lock with a reliable structure that is not prone to accidental loosening due to tensile force during use.

[0005] To achieve the above objectives, this utility model employs a lock, including a lock body, a lock rod, a lock cylinder, and a bolt. The bolt and lock cylinder are respectively distributed within the lock rod, and the lock cylinder and bolt are linked together. One end of the lock rod is connected to one end of the lock body, and the other end of the lock rod is detachably connected to the other end of the lock body. A lock hole is provided on the other end of the lock body. One end of the lock cylinder forms a lock drive part, and the other end is provided with a rotating pusher that rotates in conjunction with the drive of the lock cylinder. The bolt is horizontally distributed within the lock rod, with one end of the bolt abutting against the rotating pusher and the other end facing the lock hole. The bolt rotates through the rotating pusher, causing the bolt to extend out of the lock hole to lock or retract to unlock.

[0006] The present invention is further configured such that the lock rod includes a support, the lock cylinder passes through the support, the rotating push member passes through the support along with the lock cylinder, the lock tongue is distributed on one side of the rotating push member and is radially limited on the support, and the lock tongue slides axially within the support as the rotating push member rotates.

[0007] The present invention is further configured such that the support includes a limiting sleeve and an inner liner, the lock cylinder passes horizontally through the inner liner, and the rotating pusher passes horizontally through the inner liner along with the lock cylinder. The limiting sleeve is fitted outside the inner liner, and the limiting sleeve forms a limit on the lock cylinder and the rotating pusher falling out of the inner liner. The lock tongue is clamped between the limiting sleeve and the inner liner. The lock rod, the limiting sleeve, and the inner liner are respectively provided with lock rod through holes for the other end of the lock body to be inserted. The lock hole on the other end of the lock body that extends into the lock rod through hole and the lock tongue clamped between the limiting sleeve and the inner liner are distributed on the same straight line.

[0008] The present invention is further configured such that the lock rod also includes a lock rod seat and a lock rod cover, the support is located on the lock rod seat, the lock rod cover is provided outside the support and the open end of the lock rod cover is connected to the lock rod seat, the lock rod is connected to one end of the lock body through the lock rod seat, the other end of the lock body passes through the lock rod cover and the lock hole extends to one side of the lock tongue.

[0009] A protective cover is provided between the support and the lock rod cover, and a circumferential limiting mechanism and an axial sliding mechanism are also formed between the protective cover and the lock rod cover. The circumferential limiting mechanism limits the circumferential movement of the protective cover between the support and the lock rod cover, and the axial sliding mechanism allows the protective cover to slide axially between the support and the lock rod cover, thus enabling the lock drive unit to open or close on the lock rod.

[0010] The present invention is further configured such that a guide groove is provided on the lock tongue, and a guide slider is formed on the side of the inner liner frame facing the guide groove. The guide slider extends into the guide groove and is driven by the lock cylinder to execute a rotating pusher in a rotating linkage. Through the guide sliding cooperation between the guide slider and the guide groove, the lock tongue is guided to move towards the lock hole in the stage of extending for locking or retracting for unlocking.

[0011] The present invention is further configured such that a lock cylinder limiting block is formed on the side of the lock cylinder, and a lock cylinder anti-rotation limiting groove is provided on the inner liner for the lock cylinder limiting block to be engaged. The lock cylinder limiting block and the lock cylinder anti-rotation limiting groove are adapted to each other. Through the cooperation of the lock cylinder limiting block and the lock cylinder anti-rotation limiting groove, the circumferential rotation of the lock cylinder on the inner liner is limited.

[0012] The present invention is further configured such that the lock cylinder includes a lock cylinder fixing part and a lock cylinder rotating part that passes through the lock cylinder fixing part and performs a rotating locking or rotating unlocking action. The rotating push member is disposed on one side of the lock cylinder rotating part and is limited to the lock cylinder rotating part. The rotating push member includes a locking push part and an unlocking retraction avoidance part distributed on the side of the rotating push member. The locking push part and the unlocking retraction avoidance part are respectively distributed on the rotating trajectory line of the lock cylinder rotating part. The lock cylinder limiting block is distributed on the outer wall of the lock cylinder fixing part.

[0013] The present invention is further configured such that the circumferential limiting mechanism and the axial sliding mechanism are a protective cover limiting block formed on the protective cover relative to the side facing the lock rod cover, and a protective cover axial sliding groove opened on the lock rod cover relative to the protective cover and along the axial direction. The circumferential position of the protective cover limiting block and the protective cover axial sliding groove are adapted to each other, and the axial position is slidably set. The circumferential position adaptation setting forms a circumferential movement limit between the protective cover and the lock rod cover. The axial position sliding setting forms an axial sliding action between the protective cover and the lock rod cover, and constitutes the opening or closing of the lock drive part on the lock rod.

[0014] The present invention is further configured such that the lock drive part is a keyhole opened on the lock cylinder.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: When locking or unlocking the lock body and lock rod, the structure involves a keyhole on the lock body, a rotating pusher on the lock cylinder opposite the lock drive unit, and a bolt horizontally placed inside the lock rod. One end of the bolt abuts against the rotating pusher, while the other end faces the keyhole. This allows the lock involved in this utility model to rotate when the lock drive unit on the lock cylinder is driven by a key or other means, thereby causing the rotating pusher to rotate as well. When a certain amplitude is reached, the bolt is engaged in the keyhole, thus locking. Further rotation or reversal unlocks the bolt. Furthermore, when the lock is locked, the horizontally positioned bolt engaging in the keyhole makes it less prone to accidental loosening due to external force, compared to existing designs, thus ensuring the reliability of this utility model's design.

[0029] like Figure 1-13As shown, a specific embodiment of this utility model is a lock, including a lock body 1, a lock rod 2, a lock cylinder 4, and a bolt 6. The bolt 6 and the lock cylinder 4 are respectively distributed in the lock rod 2, and the lock cylinder 4 and the bolt 6 are linked together. One end of the lock rod 2 is connected to one end of the lock body 1, and the other end of the lock rod 2 is detachably connected to the other end of the lock body 1. A lock hole 11 is provided on the other end of the lock body 1. One end of the lock cylinder 4 forms a lock driving part a, and the other end is provided with a rotating pusher 7 that rotates in conjunction with the driving of the lock cylinder 4. The bolt 6 is horizontally distributed in the lock rod 2, and one end of the bolt 6 abuts against the rotating pusher 7, while the other end faces the lock hole 11. The bolt 6 rotates through the rotating pusher 7, forming the bolt 6 to extend out of the lock hole 11 to lock or retract to unlock. The lock driving part a is preferably a keyhole opened on the lock cylinder 4.

[0030] When locking or unlocking the lock body 1 and the lock rod 2, the structure involves a keyhole 11 on the lock body 1, a rotating pusher 7 on the lock cylinder 4 opposite to the lock drive part a, and a bolt 6 transversely placed inside the lock rod 2. One end of the bolt 6 abuts against the rotating pusher 7, while the other end faces the keyhole 11. This allows the rotating pusher 7 to be driven to rotate when the lock cylinder 4 is driven by a key or other means. The rotating action, when it reaches a certain range, can engage the bolt 6 into the lock hole 11, thus locking the device. Further rotating it to a certain range or in the opposite direction will disengage the bolt 6 from the lock hole 11, thus unlocking the device. Furthermore, when the lock is in the locked state, the locking mechanism of this invention, achieved by the horizontally positioned bolt 6 engaging the lock hole 11, makes it less prone to accidental loosening due to external pulling compared to existing locks, thus ensuring the reliability of the design.

[0031] like Figure 3-9 As shown in Figures 11-12, the lock rod 2 includes a support 5, the lock cylinder 4 passes through the support 5, the rotating pusher 7 passes through the support 5 along with the lock cylinder 4, and the latch 6 is distributed on one side of the rotating pusher 7 and is radially limited on the support 5. The latch 6 slides axially within the support 5 as the rotating pusher 7 rotates. Through the above-mentioned setting of the support 5, the lock cylinder 4 can be reliably set laterally, and the rotating pusher 7 can also be reliably set along with the lock cylinder 4. The corresponding latch 6 can also reliably slide axially within the support 5, thereby ensuring that the laterally set latch 6 can reliably lock and unlock within the lock cylinder 4 at the position of the lock body 1, thus ensuring the reliability of the lock design.

[0032] like Figure 3-9As shown in Figures 11-12, the support 5 includes a limiting sleeve 52 and an inner liner 53. The lock cylinder 4 passes horizontally through the inner liner 53, and the rotating pusher 7 passes horizontally through the inner liner 53 along with the lock cylinder 4. The limiting sleeve 52 is fitted onto the outside of the inner liner 53, and the limiting sleeve 52 forms a limit on the lock cylinder 4 and the rotating pusher 7 falling out of the inner liner 53. The lock tongue 6 is clamped between the limiting sleeve 52 and the inner liner 53. The lock rod 2, the limiting sleeve 52, and the inner liner 53 are all... Each lock body 1 has a through hole for inserting the other end of the lock rod 2. The lock hole 11 on the other end of the lock body 1, which extends into the through hole of the lock rod 2, and the lock tongue 6, which is sandwiched between the limiting sleeve 52 and the inner liner 53, are distributed on the same straight line. Through the above, the lock cylinder 4 and the lock tongue 6 can be reliably set and limited on the support 5, and the lock hole 11 of the lock body 1 extending into the lock rod 2 and the locking and unlocking actions of the lock tongue 6 are reliable.

[0033] like Figure 1-3 As shown in Figures 6, 8, 10, and 13, the locking rod 2 also includes a locking rod seat 22 and a locking rod cover 21. The support 5 is positioned on the locking rod seat 22. The locking rod cover 21 covers the outside of the support 5, and the open end 211 of the locking rod cover 21 is connected to the locking rod seat 22. The locking rod 2 is connected to one end of the lock body 1 through the locking rod seat 22. The other end of the lock body 1 passes through the locking rod cover 21, and the lock hole 11 extends to one side of the lock tongue 6. A protective cover 3 is provided between the support 5 and the locking rod cover 21, and the protective cover 3 is positioned between the locking rod cover 21 and the locking rod cover 21. It also includes a circumferential limiting mechanism and an axial sliding mechanism. The circumferential limiting mechanism limits the movement of the protective cover 3 between the support 5 and the lock rod cover 21. The axial sliding mechanism allows the protective cover 3 to slide axially between the support 5 and the lock rod cover 21, thus enabling the lock drive unit a to open or close on the lock rod 2. Through the above, a protective function can be provided on the lock to prevent accidental water or dust from entering the lock drive unit a, i.e., the keyhole of the lock.

[0034] like Figure 3-9 As shown in Figures 11-12, a guide groove 61 is provided on the latch 6. A guide slider 511 is formed on the side of the inner liner 53 facing the guide groove 61, and the guide slider 511 extends into the guide groove 61. The rotating push member 7 is driven by the lock cylinder 4 to rotate and rotate. Through the guide sliding cooperation between the guide slider 511 and the guide groove 61, the latch 6 moves towards the lock hole 11 to extend for locking or retract for unlocking. The latch 6 provided in the lock rod 2 can play a guiding role when locking or unlocking, thereby ensuring the reliable locking and unlocking of the lock involved in this utility model.

[0035] like Figure 3-5As shown in Figures 7 and 12, a lock cylinder limiting block 411 is formed on the side of the lock cylinder 4, and a lock cylinder anti-rotation limiting groove 512 is provided on the inner liner 53 for the lock cylinder limiting block 411 to engage. The lock cylinder limiting block 411 and the lock cylinder anti-rotation limiting groove 512 are adapted to each other. Through the cooperation of the lock cylinder limiting block 411 and the lock cylinder anti-rotation limiting groove 512, the circumferential rotation limit of the lock cylinder 4 on the inner liner 53 is formed. Through the above setting, the lock cylinder 4 can be reliably limited to the lock rod 2. That is, due to unreliable design, when the key is inserted into the keyhole for locking or unlocking operations, the entire lock cylinder 4 will not rotate. In other words, if the lock has the above situation, it will generally be considered that the lock is damaged.

[0036] like Figure 3-7 As shown in Figures 11-12, the lock cylinder 4 includes a lock cylinder fixing part 41 and a lock cylinder rotating part 42 that passes through the lock cylinder fixing part 41 and performs a rotating locking or rotating unlocking action. A rotating pusher 7 is disposed on one side of the lock cylinder rotating part 42 and is limited to the lock cylinder rotating part 42. The rotating pusher 7 includes a locking pusher 71 and an unlocking retraction avoidance part 72 distributed on the side of the rotating pusher 7. The locking pusher 71 and the unlocking retraction avoidance part 72 are respectively distributed on the rotation trajectory line of the lock cylinder rotating part 42. Lock cylinder limiting blocks 411 are distributed on the outer side wall of the lock cylinder fixing part 41. Through the above arrangement, the design reliability of the lock cylinder 4 can be further guaranteed. At the same time, the drive reliability of the rotating pusher 7 when pushing the bolt 6 is guaranteed. In the structural design of the rotating pusher 7, the preferred option is to design the rotating pusher 7 as a structure similar to an oblong block, that is, the locking pusher 71 is a semi-circular arc structure at both ends of the oblong block, and the unlocking retraction avoidance part 72 is a straight section in the middle of the oblong block.

[0037] like Figure 1-3 As shown in Figures 6, 8, 10, and 13, the circumferential limiting mechanism and the axial sliding mechanism are a protective cover limiting block 31 formed on the protective cover 3 relative to the side facing the lock bar cover 21, and a protective cover axial sliding groove 211 opened on the lock bar cover 21 relative to the protective cover 3 and in the axial direction. The circumferential position between the protective cover limiting block 31 and the protective cover axial sliding groove 211 is adapted, and the axial position is slidable. Through the adapted setting in the circumferential position, the protective cover 3 is circumferentially limited between the support 5 and the lock bar cover 21. Through the axial sliding setting, the protective cover 3 is axially slidable between the support 5 and the lock bar cover 21, and constitutes the opening or closing of the lock drive unit a on the lock bar 2. Through the above, the design of the protective cover 3 involved in the lock can be made reliable, and reliable limiting can be performed. The opening or closing of the keyhole can be reliably driven.
