Technical Field
[0001] The utility model relates to the technical field of window safety structures, and particularly relates to a window safety lock. Background Art
[0002] In modern life, locks are applied to a very large number of scenarios, such as objects that require a certain degree of safety protection, such as doors, windows, or cabinets. In the structure of a mechanical lock, holes are usually provided on the lock body, and mechanical components such as lock tongues are arranged along the outer circle of the holes, so that people can open the lock with a key on the outside of the lock, or directly activate the unlocking structure on the inside to open the lock. However, the above mechanical lock has the following problems: lawbreakers use a thin wire to pass through the hole on the outside of the lock to open it. This approach will, on the one hand, damage the lock, and on the other hand, cause the lock to lose its anti-theft function and have low safety protection. Therefore, a solution needs to be proposed for this problem. Content of the Utility Model
[0003] In view of the deficiencies of the prior art, the utility model provides a window safety lock, which can ensure the stability and safety of the window when locked and prevent it from being damaged from the outside.
[0004] The technical solution of the utility model is realized as follows:
[0005] A window safety lock includes a base, a stop seat, at least two lock members provided outside the stop seat, and at least two elastic members. The stop seat, the lock members, and the elastic members are all arranged on the base; at least two stop grooves are provided on the stop seat. The lock member includes a lock tongue and a lock handle. The lock tongue and the lock handle are respectively located on opposite sides outside the stop seat. When locked, the lock tongue is located in the stop groove; the lock handle is connected to the elastic member, and the elastic member is used to drive the lock handle to reset.
[0006] Preferably, the two stop grooves are respectively arranged on the left and right sides or the upper and lower sides of the stop seat, and the two lock tongues are arranged on the left and right sides or the upper and lower sides of the stop seat corresponding to the stop grooves.
[0007] Preferably, the elastic member is connected to the lock handle and the side wall of the base where the lock handle is located.
[0008] Preferably, a limiting member is further provided on the base. The limiting member is located between the lock handle and the stop seat, and the two ends of the elastic member are respectively connected to the limiting member and the lock handle.
[0009] Preferably, at least two limiting seats are further provided on the base. At least one limiting groove is provided on the limiting seat, and one end of the elastic member is arranged in the limiting groove and the other end is connected to the lock handle.
[0010] Preferably, the number of the limiting grooves on the limiting seat is 2, and the limiting grooves are provided with elastic members of the same number.
[0011] Preferably, it further comprises a button, one end of which is connected to the lock handle, and the other end of which extends out of the outer side of the base.
[0012] Preferably, the button and the lock handle are integrally formed or detachably connected.
[0013] Preferably, the cross-sectional shape of the base is rectangular or circular.
[0014] Compared with the prior art, the utility model has the following advantages:
[0015] The utility model is installed on the base where the window handle is located, wherein the rotating shaft of the handle passes through the stop seat and extends outside the utility model, and people open the window by turning the handle. When the handle needs to be turned, that is, when the safety lock needs to be opened, only the lock handles on the two locks need to be pressed at the same time, and the lock handles drive the corresponding lock tongues to move out of the stop grooves, so that the stop seat is no longer restricted by the lock tongue, so that people can turn the handle, wherein the elastic member is pulled while the lock handle moves, and undergoes elastic deformation; when the handle needs to be locked, the pressing of the lock handle is first released, and the force pressing the lock handle is removed. At this time, the elastic member is no longer subjected to external force, resets itself, and drives the lock handle to reset, and further drives the lock tongue to reset to the corresponding stop groove. When the elastic member is reset, the lock tongues of the two locks are both located in the corresponding stop grooves on the stop seat, and the lock tongues are clamped in the stop grooves. The two cooperate to fix the entire safety lock and the handle, so that they no longer move, thereby achieving the purpose of locking the handle. It should be noted that the lock cannot be opened by only pressing one lock handle to make one lock tongue disengage from the stop groove. The unlocking work can only be completed when both lock tongues leave the stop grooves. This structure can also prevent criminals from using a thin wire to pass through the stop seat from outside the window to open it, so that the lock cannot be destroyed from outside the window; and the mutual cooperation of the two locks and the stop grooves can only be opened through the above-mentioned specific method. This double locking structure can ensure the stability and safety of window locking. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
[0024] See Figures 1 to 5 , the present embodiment of the present utility model discloses a window safety lock, including a base 1, a stop seat 2, at least two locking members 3 provided outside the stop seat 2, and at least two elastic members 4. The stop seat 2, the locking members 3, and the elastic members 4 are all provided on the base 1; at least two stop grooves 21 are provided on the stop seat 2. The locking member 3 includes a locking tongue 31 and a locking handle 32. The locking tongue 31 and the locking handle 32 are respectively located on opposite sides outside the stop seat 2. When locked, the locking tongue 31 is located in the stop groove 21; the locking handle 32 is connected to the elastic member 4, and the elastic member 4 is used to drive the locking handle 32 to reset.
[0025] The number of the locking members 3 and the stop grooves 21 is preferably 2. To better illustrate the usage mode of the present utility model, the following descriptions are all based on the structure where the number of both the locking members 3 and the stop grooves 21 is 2.
[0026] The present utility model is installed on the base 1 at the position where the window handle is located. Among them, the rotating shaft of the handle passes through the positioning seat 2 and extends outside the present utility model, and people can open the window by rotating the handle. When it is necessary to rotate the handle, that is, when it is necessary to unlock the safety lock, only need to simultaneously press the lock handles 32 on the two lock members 3, and drive the corresponding lock tongues 31 through the lock handles 32 to move out of the positioning grooves 21, so that the positioning seat 2 is no longer restricted by the lock tongues 31, so that people can rotate the handle. Among them, the elastic member 4 is pulled while the lock handle 32 moves, and undergoes elastic deformation; when it is necessary to lock the handle, first release the pressing on the lock handle 32, remove the force pressing on the lock handle 32. At this time, the elastic member 4 is no longer subjected to an external force and resets itself. At the same time, it drives the lock handle 32 to reset, and further drives the lock tongue 31 to reset to the corresponding positioning groove 21. When the elastic member 4 completes the reset, the lock tongues 31 of the two lock members 3 are both located in the corresponding positioning grooves 21 on the positioning seat 2, and the lock tongues 31 are clamped in the positioning grooves 21, and the two cooperate to fix the entire safety lock and the handle, so that they no longer move, achieving the purpose of locking the handle. It should be noted that only pressing one lock handle 32 to make one lock tongue 31 disengage from the positioning groove 21 cannot unlock the lock. Only when both lock tongues 31 leave the positioning groove 21 can the unlocking work be completed, and this structure can also prevent criminals from using a thin wire to pass through the positioning seat 2 from outside the window to open it, so that the lock cannot be damaged from outside the window; and the mutual cooperation of the two lock members 3 and the positioning grooves 21 can only be opened through the above specific method. This double-locking structure can ensure the stability and safety of the window lock.
[0027] See Figure 5 , specifically, the positioning grooves 21 can also be provided on any two sides of the positioning seat 2. For example, taking the center of the positioning seat 2 as the origin of the coordinate axis, the positioning grooves 21 are provided on the due north and due east of the origin, or due east and due south, or due south and due west, or due west and due north, or due north and due south, or due east and due west, or are provided on the northeast and southeast sides according to the actual structure, or on the northwest and southwest sides. The position of the positioning grooves 21 is not limited to the above examples, and other positions that can achieve the same unlocking principle are also within the protection scope of the present utility model.
[0028] The preferred structure of the positioning grooves 21 and the lock members 3 in the present utility model is that the two positioning grooves 21 are respectively provided on the left and right sides or the upper and lower sides of the positioning seat 2, and the two lock tongues 31 are correspondingly provided on the left and right sides or the upper and lower sides of the positioning seat 2 corresponding to the positioning grooves 21. Correspondingly, the two lock handles 32 are respectively provided on the right and left sides or the lower and upper sides of the positioning seat 2. This structure enables people to unlock the lock only by using the force to press the lock handles 32 towards each other, which is very convenient.
[0029] Embodiment 1
[0030] See Figure 1, the elastic member 4 connects the lock handle 32 and the side wall of the base 1 where the lock handle 32 is located. In this structure, when unlocking is required, the lock handle 32 is pressed, and the corresponding lock tongue 31 leaves the stop groove 21. At this time, the lock handle 32 drives the elastic member 4 to undergo a tensile elastic deformation; when locking is required, the force pressing the lock handle 32 is removed. At this time, the elastic member 4 is not pressed by an external force and automatically retracts and resets, thereby driving the lock handle 32 and the lock tongue 31 to reset together to complete the locking work.
[0031] Embodiment 2
[0032] See Figure 2 , a limiting member 5 is further provided on the base 1. The limiting member 5 is located between the lock handle 32 and the stop seat 2, and both ends of the elastic member 4 are respectively connected to the limiting member 5 and the lock handle 32. Specifically, the number of the limiting members 5 is the same as the number of the locking members 3.
[0033] In this structure, when unlocking is required, the lock handle 32 is pressed, and the corresponding lock tongue 31 leaves the stop groove 21. At the same time, since one end of the elastic member 4 connected to the limiting member 5 limits it, the lock handle 32 compresses the elastic member 4 to cause it to undergo a retracting elastic deformation; when locking is required, the force pressing the lock handle 32 is removed. At this time, the elastic member 4 is not pressed by an external force and automatically stretches and resets, thereby driving the lock handle 32 and the lock tongue 31 to reset together to complete the locking work.
[0034] Preferably, 2 elastic members 4 are provided on a single limiting member 5, so that the mutual acting forces between the lock handle 32 and the elastic member 4 can be balanced, and the uneven force on the lock handle 32 during the process of pressing the lock handle 32 can be prevented from affecting the position matching work between the lock tongue 31 and the stop groove 21.
[0035] Embodiment 3
[0036] See Figures 3 - 4 , at least 2 limiting seats 6 are further provided on the base 1. At least 1 limiting groove 61 is provided on the limiting seat 6, one end of the elastic member 4 is arranged in the limiting groove 61, and the other end is connected to the lock handle 32. In this structure, when unlocking is required, the lock handle 32 is pressed, and the corresponding lock tongue 31 leaves the stop groove 21. At the same time, since one end of the elastic member 4 connected to the limiting groove 61 limits it, the lock handle 32 compresses the elastic member 4 to cause it to undergo a retracting elastic deformation; when locking is required, the force pressing the lock handle 32 is removed. At this time, the elastic member 4 is not pressed by an external force and automatically stretches and resets, thereby driving the lock handle 32 and the lock tongue 31 to reset together to complete the locking work. The difference between this embodiment and Embodiment 2 is that the limiting groove 61 can better limit the moving direction of the elastic member 4 when it undergoes elastic deformation, and has a better moving effect.
[0037] Further, the number of the limiting grooves 61 on the limiting seat 6 is two, and correspondingly, an equal number of elastic members 4 are provided in the limiting grooves 61. This structure can, on the one hand, balance the interaction force between the lock handle 32 and the elastic members 4, preventing the uneven force on the lock handle 32 during the pressing process from affecting the position matching operation between the lock tongue 31 and the stop groove 21.
[0038] Embodiment 4
[0039] See Figure 5 , the structure of the limiting seat 6, the limiting groove 61, and the limiting member 5 can also be provided on the base 1 at the same time. Just set the corresponding limiting groove 61 or limiting member 5 according to the actual structure of the lock member 3.
[0040] Further, a key 7 is further included. One end of the key 7 is connected to the lock handle 32, and the other end extends out of the outer side of the base 1. It is convenient for a human hand to press the lock handle 32 by holding the key 7, improving the convenience of pressing the lock member 3.
[0041] Further, the key 7 and the lock handle 32 are integrally formed or detachably connected. This structure can strengthen the connection stability between the key 7 and the lock handle 32, avoiding the loosening of parts and the inability to open the lock.
[0042] Further, the cross-sectional shape of the base 1 is rectangular or circular. Specifically, the rectangular base 1 is suitable for the structure where two lock members 3 are respectively arranged on opposite sides of the stop seat 2, such as the upper and lower sides, or the left and right sides; the circular base 1 is suitable not only for the structure where two lock members 3 are respectively arranged on opposite sides of the stop seat 2, but also for the structure where two lock members 3 are arranged on adjacent sides, such as the left and upper sides, the upper and right sides, the right and lower sides, and the lower and left sides.
[0043] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
