[0001] The utility model relates to the technical field of sliding door and window locks, in particular to a sliding window strip lock. Background Art

[0002] Sliding window bar lock is a kind of lock for sliding window, which prevents the window from being opened or closed accidentally. This kind of lock is usually installed on sliding window, locking the movement of window by physical or mechanical means.

[0003] After searching, the Chinese patent authorization number CN208122557U discloses a straight lock for sliding doors and windows with a locking structure. The straight lock for sliding doors and windows can lock or unlock the sliding part by driving the rotating part to rotate.

[0004] Although the above lock can lock the sliding member from the inside to prevent the lock from being accidentally opened from the inside, the above lock lacks an anti-pry structure to prevent the lock from being pried open from the outside. Once the lock is pried open from the outside, the thief can drive the rotating member and the shift fork from the outside to unlock the sliding window, which poses a safety hazard. Utility Model Content

[0005] The utility model aims to provide a sliding window strip lock, wherein the sliding part can be telescopically arranged on the inner side, so that the shift fork cannot be driven to unlock from the outer side, thereby improving the anti-pry performance of the sliding window.

[0006] In a first aspect, the utility model provides a sliding window strip lock, comprising:

[0007] A lock base, provided with a first hole, a second hole and a receiving cavity, wherein the first hole and the second hole are provided on opposite sides of the lock base, and the first hole and the second hole are both communicated with the receiving cavity;

[0008] A sliding member is arranged in the accommodating cavity, a shift fork is provided on one side of the sliding member, and the shift fork is movably arranged in the first hole, and a push-pull portion is provided on the other side of the sliding member, and the push-pull portion is telescopically arranged on the sliding member, and the push-pull portion can extend out of the second hole to limit the movement of the shift fork in the first hole.

[0009] The utility model provides a sliding window strip lock, in which the first hole of the lock seat can be installed toward the outside of the sliding window, and the second hole can be installed toward the inside of the sliding window. The sliding part is retractably arranged on the sliding member, and the user can only realize the movement of the sliding member in the accommodating cavity after pressing the sliding part from the inside to retract it into the second hole, thereby driving the shift fork to move in the first hole; and the sliding part can be engaged with the lock seat after extending out of the second hole to limit the movement of the shift fork in the first hole. The sliding window strip lock can lock the shift fork from the inside, and even if the lock is pried open from the outside by a thief, the shift fork cannot be driven from the outside to move and unlock, which helps to improve the anti-pry performance of the sliding window.

[0010] Further, the push-pull portion includes a first push-pull portion and a second push-pull portion, the first push-pull portion is arranged at an end of the sliding member away from the fork, and the second push-pull portion is arranged at an end of the sliding member close to the fork, and at least one of the first push-pull portion and the second push-pull portion can be telescopically arranged on the sliding member.

[0011] Furthermore, a T-shaped slot is provided on the sliding member, a T-shaped block is provided on the push-pull portion, the T-shaped block is clamped in the T-shaped slot, and an energy storage member is provided between the T-shaped block and the bottom of the T-shaped slot, the push-pull portion can drive the T-shaped block to move in the T-shaped slot so that the energy storage member accumulates driving force; the energy storage member can also release driving force to drive the push-pull portion to extend out of the second hole.

[0012] By adopting the above technical solution, the energy storage part can control the extension and retraction of the T-shaped card block in the T-shaped card slot. When the user presses the push-pull part to retract and unlock it, the energy storage part can accumulate driving force. When the sliding part needs to be locked, the user only needs to release the pressure on the push-pull part, and the energy storage part can release the driving force to drive the push-pull part to automatically extend out of the second hole for locking. This can avoid the situation where the user forgets to pull out the push-pull part, resulting in the loss of the anti-pry function, and is easy to use.

[0013] Furthermore, the number of the energy storage components is at least two, and at least two of the energy storage components are spaced apart in the T-shaped slot.

[0014] By adopting the above technical solution, the driving force of the energy storage members can be increased by increasing the number of energy storage members, which helps to reduce the occurrence of failure of the push-pull part to automatically extend due to insufficient driving force.

[0015] Further, the energy storage component is an elastic component; or, the energy storage component is a magnetic component.

[0016] Furthermore, it also includes a return spring, which is arranged between the sliding member and the lock seat. The push-pull part can drive the sliding member to move in the accommodating cavity so that the return spring accumulates elastic force; the return spring can also release elastic force to drive the sliding member to reset.

[0017] Furthermore, the number of the return springs is two, and the two return springs are respectively arranged on opposite sides of the sliding member.

[0018] Furthermore, the lock seat is also provided with a third hole, and the third hole is arranged on the side where the second hole is located. A rotatable locking portion is provided in the third hole, and a locking hole is provided on the locking portion. A locking shaft is provided at one end of the sliding member facing the locking hole, and the locking portion can be rotated to align the locking hole with the locking shaft for the locking shaft to be inserted and moved; the locking portion can also be rotated to limit the movement of the locking shaft.

[0019] By adopting the above technical solution, by driving the locking part to rotate relative to the locking shaft, when the locking hole is aligned with the locking shaft, the sliding part can move in the accommodating cavity; when the locking hole avoids the locking shaft, the side surface of the locking part abuts against the locking shaft, and the locking part can limit the movement of the sliding part in the accommodating cavity. The above solution can effectively prevent children from accidentally unlocking the door, thereby ensuring the personal safety of children.

[0020] Furthermore, it also includes a key, the key is provided with an insert block, the locking part is provided with a slot, the insert block can be inserted into the slot, so that the key drives the locking part to rotate.

[0021] Furthermore, a symmetrically arranged first elastic arc petal and a second elastic arc petal are also provided in the accommodating cavity, and a rotation limiting portion is also provided on the side of the locking portion facing away from the third hole. The circumference of the rotation limiting portion is sequentially provided with a first plane, a first limiting arc surface, a second plane and a second limiting arc surface, the first plane and the second plane are relatively arranged, the first limiting arc surface and the second limiting arc surface are symmetrically arranged, the shortest distance between the first elastic arc petal and the second elastic arc petal is h1, the distance between the first plane and the second plane is h2, and the maximum distance between the first limiting arc surface and the second limiting arc surface is h3, wherein h2

[0022] ​By adopting the above technical solution, by setting the first elastic arc petal, the second elastic arc petal and the rotation limiting portion, when the first limiting arc surface and the second limiting arc surface abut against the first elastic arc petal and the second elastic arc petal, the locking hole and the locking shaft are staggered, and when the first plane and the second plane are facing the first elastic arc petal and the second elastic arc petal, the locking hole is set toward the locking shaft; the user can control the relative position between the locking hole and the locking shaft by identifying the torque required to turn the key, so that the user can easily align the locking hole and the locking shaft.

[0023] As can be seen from the above, the sliding window strip lock provided by the utility model has a first hole of the lock seat that can be installed toward the outside of the sliding window, and a second hole that can be installed toward the inside of the sliding window. The push-pull portion is retractably arranged on the sliding member, and the user can only realize the movement of the sliding member in the accommodating cavity after pressing the push-pull portion from the inside to retract it into the second hole, thereby driving the shift fork to move in the first hole; and the push-pull portion can be engaged with the lock seat after extending out of the second hole to limit the movement of the shift fork in the first hole. The sliding window strip lock can lock the shift fork from the inside, and even if the lock is pried open from the outside by a thief, the shift fork cannot be driven from the outside to move and unlock, which helps to improve the anti-pry performance of the sliding window.
