Description

Technical Field

[0001] This utility model relates to the field of lock-related technology, and in particular to a lock frame with a buffer and anti-collision function. Background Technology

[0002] The lock frame, also known as the lock body, is the shell structure that wraps around the transmission components in a lock. It mainly provides protection for the transmission components and is also the structure assembled with the door. It is an indispensable and important component of a lock.

[0003] Existing locks with square latches extend from the lock frame and insert into the keyhole on the door frame via an internal transmission structure to lock the door. However, most existing lock frames have through holes on the guide plates that fit the square latch, preventing it from moving laterally. Furthermore, the internal transmission structure lacks buffering components for the square latch. This results in the square latch failing to retract into the lock frame after opening, causing it to impact the door frame during closing. The resulting vibrations can easily damage the square latch and cause misalignment or breakage of the internal transmission structure, rendering the lock frame and internal transmission structure unusable. Therefore, there is room for improvement. Utility Model Content

[0004] The purpose of this utility model is to provide a lock frame with a buffer and anti-collision function to solve the problem mentioned in the background art that the existing lock frame does not have a component structure to buffer the latch lock, which causes the latch lock to fail to retract into the lock frame and the door to directly drive the latch lock to impact the door frame when the door is closed, resulting in vibration that can easily damage the door, door frame, lock frame and internal transmission structure.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a lock frame with buffer and anti-collision function, comprising a lock frame body, a guide plate fixedly connected to the front of the lock frame body, a square groove opened on the front of the guide plate, a transmission structure provided on the inner wall of the lock frame body, the transmission structure comprising a square tongue slide plate slidably connected to the inner wall of the lock frame body, a buffer component connected to the square tongue slide plate, and a square tongue lock connected to the buffer component. The buffer assembly includes a first buffer mechanism and a second buffer mechanism. The first buffer mechanism is used to reduce the impact force between the latch lock and the door frame when the latch lock is not closed. The second buffer mechanism is used to provide buffer protection for the lock frame body and the internal transmission structure.

[0006] Preferably, the first buffer mechanism includes a positioning frame, which is fixedly connected to the side of the square tongue slide plate near the guide plate. The square tongue lock is slidably connected to the inner wall of the square groove, and the width of the square groove is greater than the width of the square tongue lock. A buffer groove and a triangular groove are provided on the side of the positioning frame away from the square tongue slide plate. A positioning shaft is fixedly connected to the inner wall of the buffer groove. A first buffer spring is sleeved on the surface of the positioning shaft. A locking circular plate is fixedly connected to the right end of the positioning shaft. A slider is slidably connected to the inner wall of the buffer groove. The side of the slider away from the positioning frame is fixedly connected to the square tongue lock. When the square tongue lock hits the door frame, it can move in the square groove and drive the slider to squeeze the first buffer spring, thereby providing a certain buffering effect on the square tongue lock and the door.

[0007] Preferably, the buffer groove is connected to the triangular groove, the thickness of the slider is greater than the thickness of the buffer groove, the slider is slidably connected to the surface of the positioning shaft, the left end of the first buffer spring overlaps with the right side of the slider, the end of the first buffer spring away from the slider overlaps with the left side of the locking circular plate, and the diameter of the locking circular plate is greater than the diameter of the positioning shaft. The two ends of the first buffer spring are respectively squeezed and restricted by the slider and the locking circular plate, which deforms on the surface of the positioning shaft and absorbs energy from the impact.

[0008] It should be noted that since the diameter of the locking plate is larger than the diameter of the positioning shaft, the slider will not detach from the surface of the positioning shaft during the rightward movement. Furthermore, the space on the left side of the locking plate is sufficient to support the deformation of the first buffer spring, preventing the first buffer spring from detaching from the surface of the positioning shaft.

[0009] Preferably, the second buffer mechanism includes a circular shaft, which is fixedly connected to the inner bottom wall of the triangular groove. Two movable blocks are slidably connected to the right inner wall of the triangular groove. Two second buffer springs are sleeved on the surface of the circular shaft. The two movable blocks can slide on the surface of the circular shaft to squeeze the second buffer springs, causing the second buffer springs to deform.

[0010] Preferably, both movable blocks are slidably connected to the surface of the circular shaft, and the opposite ends of the two second buffer springs overlap with the opposite backs of the two movable blocks respectively. The ends of the two second buffer springs away from the movable blocks overlap with the inner bottom wall and the inner top wall of the triangular groove respectively. Due to the restriction effect of the inner wall of the triangular groove, the two movable blocks can slide stably on the surface of the circular shaft without deflection.

[0011] Preferably, a first rotating frame is fixedly connected to the left side of each of the two movable blocks, a fixed rod is fixedly connected to the inner wall of the first rotating frame, and a transmission plate is rotatably connected to the surface of the fixed rod.

[0012] Preferably, two second rotating frames are fixedly connected to the right side of the slider. A locking rod is fixedly connected to the inner wall of each of the two second rotating frames. The locking rod is rotatably connected to the end of the transmission plate away from the fixed rod. During the movement of the slider to the right, it can drive the two second rotating frames to the right, thereby applying power to the two movable blocks through the transmission plate that rotates with the fixed rod and the locking rod, thereby driving the two movable blocks to move away from each other and compress the second buffer spring.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This lock frame with buffer and anti-collision function, through the setting of the first buffer mechanism, can reduce the impact of the square tongue lock hitting the door frame on the door body and the lock structure on the door body by using the square tongue lock to drive the slider to move to the right and cooperate with the locking round plate to squeeze the first buffer spring during use. At the same time, it can also avoid damage to the square tongue lock by impact, thereby improving the buffer and anti-collision protection effect on the door body, lock frame body and the transmission structure inside the lock frame body.

[0014] 2. This lock frame with buffer and anti-collision function, through the setting of the second buffer mechanism, when the door body drives the square latch to hit the door frame with excessive force, the first buffer spring cannot completely absorb the impact force. At this time, the slider can drive the two second rotating frames to move to the right during the rightward movement. The two second rotating frames cooperate with the locking rod and the transmission plate, and achieve transmission compression of the first rotating frame through the fixed rod. After being compressed, the two first rotating frames can drive the two movable blocks to move away from each other on the surface of the circular shaft, thereby compressing the two second buffer springs. The two second buffer springs can increase the energy absorption effect of the impact force, thereby further improving the protection effect of the door body, door frame, lock frame body and internal transmission structure, and extending the service life of the lock frame body and internal transmission structure.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: Example 1: A lock frame with buffer and anti-collision function includes a lock frame body 1, a guide plate 2 is fixedly connected to the front of the lock frame body 1, a square groove 3 is opened on the front of the guide plate 2, and a transmission structure is provided on the inner wall of the lock frame body 1. The transmission structure includes a square tongue slide plate 4 slidably connected to the inner wall of the lock frame body 1, a buffer component 5 is connected to the square tongue slide plate 4, and a square tongue lock 6 is connected to the buffer component 5. The buffer assembly 5 includes a first buffer mechanism 51 and a second buffer mechanism 52. The first buffer mechanism 51 is used to reduce the impact force between the square latch lock 6 and the door frame when the square latch lock 6 is not closed. The second buffer mechanism 52 is used to provide buffer protection for the lock frame body 1 and the internal transmission structure.

[0019] Furthermore, the first buffer mechanism 51 includes a positioning frame 5101, which is fixedly connected to the side of the square tongue slide plate 4 near the guide plate 2. The square tongue lock 6 is slidably connected to the inner wall of the square groove 3, and the width of the square groove 3 is greater than the width of the square tongue lock 6. A buffer groove and a triangular groove are provided on the side of the positioning frame 5101 away from the square tongue slide plate 4. A positioning shaft 5102 is fixedly connected to the inner wall of the buffer groove. A first buffer spring 5103 is sleeved on the surface of the positioning shaft 5102. A locking circular plate 5104 is fixedly connected to the right end of the positioning shaft 5102. The inner wall of the groove is slidably connected to a slider 5105. The side of the slider 5105 away from the positioning frame 5101 is fixedly connected to the square tongue lock 6. The buffer groove is connected to the triangular groove. The thickness of the slider 5105 is greater than the thickness of the buffer groove. The slider 5105 is slidably connected to the surface of the positioning shaft 5102. The left end of the first buffer spring 5103 overlaps with the right side of the slider 5105. The end of the first buffer spring 5103 away from the slider 5105 overlaps with the left side of the locking round plate 5104. The diameter of the locking round plate 5104 is greater than the diameter of the positioning shaft 5102. When the square latch 6 is not closed, during the closing process, the door body will cause the square latch 6 to directly impact the door frame. At this time, due to the squeezing effect of the door frame, the square latch 6 can move to the right within the square groove 3. The square latch 6 causes the slider 5105 to move to the right, thereby causing the slider 5105 to squeeze the first buffer spring 5103 on the surface of the positioning shaft 5102. The first buffer spring 5103 is squeezed by the slider 5105 on the left and blocked by the locking round plate 5104 on the right, which can generate deformation, thereby absorbing the impact force and reducing the impact force on the door body and the lock on the door body. At the same time, it can also protect the square latch 6 itself.

[0020] Example 2: The second buffer mechanism 52 includes a circular shaft 5201, which is fixedly connected to the inner bottom wall of a triangular groove. Two movable blocks 5202 are slidably connected to the right inner wall of the triangular groove. Two second buffer springs 5203 are sleeved on the surface of the circular shaft 5201. Both movable blocks 5202 are slidably connected to the surface of the circular shaft 5201, and the opposite ends of the two second buffer springs 5203 respectively overlap with the opposite back surfaces of the two movable blocks 5202. The ends of the two second buffer springs 5203 away from the movable blocks 5202 are... Do not overlap with the inner bottom wall and inner top wall of the triangular groove. The left side of each of the two movable blocks 5202 is fixedly connected to a first rotating frame 5204. The inner wall of the first rotating frame 5204 is fixedly connected to a fixing rod 5205. The surface of the fixing rod 5205 is rotatably connected to a transmission plate 5206. The right side of the slider 5105 is fixedly connected to two second rotating frames 5207. The inner wall of each of the two second rotating frames 5207 is fixedly connected to a locking rod 5208. The locking rod 5208 is rotatably connected to the end of the transmission plate 5206 away from the fixing rod 5205. When the force of the door body driving the square tongue lock 6 to hit the door frame is too great, the first buffer spring 5103 still cannot completely absorb and buffer the impact force even with its extreme deformation. At this time, during the rightward movement of the slider 5105, it can drive the two movable blocks 5202 to move away from each other on the surface of the circular shaft 5201 through the cooperation of the second rotating frame 5207, the locking rod 5208 and the transmission plate 5206. The two movable blocks 5202 can squeeze the second buffer spring 5203 on the surface of the circular shaft 5201. The two second buffer springs 5203 increase the energy absorption effect of the impact force, thereby reducing the impact of vibration on the door body, door frame, lock frame body 1 and internal transmission structure, further improving the protection effect of the lock frame body 1 and internal transmission structure, and extending the service life of the lock frame body 1.

[0021] Working principle: Under normal use, the square tongue slide plate 4 can drive the square tongue lock 6 to pass through the square slot 3 and insert into the door frame through the positioning frame 5101 and the slider 5105, realizing the locking function of the door. When the square tongue lock 6 fails to retract into the square slot 3 and the door hits the door frame, the square tongue lock 6 directly impacts the door frame. At this time, the square tongue lock 6 is impacted by the door frame and moves to the right within the square slot 3. The square tongue lock 6 can drive the slider 5105 to move to the right on the surface of the positioning shaft 5102 and cooperate with the locking round plate 5104 to compress the first buffer spring 5103. The first buffer spring 5103 can absorb the impact force, thereby preventing the square tongue lock 6 from being damaged by impacting the door frame. In addition, When the impact force is too great and causes the first buffer spring 5103 to deform to its limit, the slider 5105 can move to the right and, through the cooperation of the two second rotating frames 5207, the locking rod 5208 and the transmission plate 5206, drive the two movable blocks 5202 to move away from each other on the surface of the circular shaft 5201. At this time, the two movable blocks 5202 can be driven by the transmission effect of the transmission plate 5206, squeezing the two second buffer springs 5203 on the surface of the circular shaft 5201. The two second buffer springs 5203 increase the energy absorption effect, thereby effectively reducing the vibration impact on the door body, lock frame body 1 and internal transmission structure when the impact force is too great, and providing good protection for the lock frame body 1 and internal transmission structure.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
