Technical Field
[0001] This utility model relates to the field of lock technology, and in particular to a locking mechanism that establishes a lock by capturing an impacting element with a claw. Background Technology
[0002] Existing locking mechanisms that use pawls to capture impacting elements to establish a lock are generally unlocked by manually operating a handle or lever to drive the pawls. The handle or lever extends beyond the lock housing and has a certain length, affecting the overall shape of the lock and requiring force to operate. This method is inconvenient in practical applications. Therefore, locking mechanisms are specially adjusted, designed, or selected for specific applications and environments, such as the need for locking and maintaining the position of the handle and door, and the proximity distance between the lock and the doorpost when the locking mechanism is activated. These factors also limit the widespread application of locking mechanisms. Summary of the Invention

[0025] The following will further explain the concept, specific structure and technical effects of the utility model in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of the utility model.
[0026] It should be noted that in the description of this utility model, the terms "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," which indicate directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These terms are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0027] See Figure 1 , 2 Figures 3, 4, 5, 6, and 7 are schematic diagrams of a preferred embodiment of this utility model. This utility model relates to a handle lock that enables the claw to capture an impacting element to establish a locking connection, while also providing a handle gripping function, greatly improving practicality and versatility to meet the needs of various applications. The handle lock comprises: a housing 1, a claw 2, a locking element 5, and an unlocking element 6.
[0028] The housing 1 has a receiving groove 11 and a handle 12 located on one side of the receiving groove. The receiving groove 11 has a notch 111. Furthermore, the handle 12 and the notch 111 of the receiving groove 11 are positioned opposite each other, which facilitates the construction of the handle 12 and makes it easier to grip, making closing and opening the door easier and more comfortable. Furthermore, the handle 12 is a U-shaped structure with a clearance through-hole, which facilitates finger insertion and gripping, resulting in a robust structure and stable grip. In this embodiment, the two ends of the handle 12 protrude opposite each other for connection to the door body, such as by using screws for fastening, facilitating disassembly and maintenance.
[0029] The latch 2 is assembled in the receiving groove 11 and can rotate relative to it in both directions. A first torsion spring 31 is introduced between the latch 2 and the housing 1, supporting the latch 2 and keeping it in a set locking posture. The latch 2 has a hook portion 21 and an anti-detachment portion 22. The hook portion 21 is in the form of a U-shaped groove, and receives the impact member 4 through the notch 111 of the receiving groove 11, thereby establishing a locking connection. The impact member 4 is set on the door frame. The impact member 4 can be built into the door frame or assembled from multiple parts, depending on the actual situation. Figure 5 , 6 As shown in Figure 7, the impact member 4 is in the form of a crossbar and is fixed to the door frame by a mounting bracket. When the door is closed, the impact member 4 impacts the pawl 2 by relative motion, overcoming the supporting force of the first torsion spring 31. The pawl 2 rotates relative to the impact member, and the impact member 4 slides into the hook opening 21. Then, the first torsion spring 31 supports the pawl 2 to rotate back to its original position and maintain the set locking posture, thereby capturing the impact member to establish the door lock state.
[0030] The locking member 5 is assembled in the receiving groove 11 and can rotate relative to it. A second torsion spring 32 is introduced between the locking member 5 and the housing 1. The second torsion spring 32 supports the locking member 5, keeping it in a set locked posture. The locking member 5 is provided with a locking part 51 and an unlocking part 52. In the locked posture, the locking part 51 is engaged with the anti-disengagement part 22 of the pawl 2, restricting the pawl from rotating in the corresponding direction and limiting the release of the impact member 4 from the hook part 21, which is the locking function.
[0031] The unlocking component 6 is assembled on the housing 1 and can move relative to it. The unlocking component 6 has an unlocking end 61 and a pressing end 62. The unlocking end 61 extends into the receiving groove 11 and drives the locking component 5, causing the locking part 51 to disengage from the anti-disengagement part 22, restoring the corresponding rotation of the pawl. At this point, by overcoming the supporting force of the first torsion spring 31, the pawl 2 rotates relative to the locking part 21, which then rotates outward and releases the impact member 4, thus unlocking the door and allowing it to be opened. The pressing end 62 extends to and protrudes from the handle part 12 for user operation. Thus, while holding the handle part 12, the user can press the pressing end 62 with their finger to drive the locking component 5 through the unlocking end 61, thereby unlocking the door. The pressing method for unlocking is easy and convenient.
[0032] In this embodiment, the receiving groove 11 is further provided with a guide block 7. The guide block 7 and the claw 2 are respectively located on the left and right sides of the impact direction of the impactor 4. The hook portion 21 of the claw 2 faces the guide block 7, and the guide block 7 has an inlet surface 71 facing the claw 2. This structural design facilitates the impactor 4 to slide in upon impact, and the hook portion 21 of the claw 2 can stably and effectively receive the impactor 4, improving the locking performance.
[0033] Figure 3 As shown, in this embodiment, the receiving groove 11 is composed of a U-shaped base 13 and a rear cover 14. The U-shaped base 13 and the handle 12 are integrally formed, resulting in good structural integrity and ease of manufacturing. The notch 111 of the receiving groove extends to both the U-shaped base 13 and the rear cover 14, matching the impact member 4 for impact and sliding into operation. The U-shaped base 13 is provided with multiple positioning posts 131, which are respectively inserted into positioning holes to match the claw 2, locking member 5, and guide block 7 for positioning and assembly, resulting in a convenient assembly and a compact and stable system between components. In this embodiment, the first torsion spring 31 and the second torsion spring 32 are also respectively sleeved on the corresponding positioning posts 131, facilitating positioning and assembly. The rear cover 14 is locked to the U-shaped base 13 by screws 8, which precisely lock into the pre-set threaded holes on the positioning posts 131, facilitating assembly and maintenance. This structural design achieves simplicity, compactness, and effective cost reduction, which is conducive to widespread application.
[0034] In this embodiment, the anti-detachment part 22 is a tooth protruding on the outer periphery of the claw, and the locking part 51 on the locking member 5 is a hook. The locking part 51 and the unlocking part 52 are respectively located at both ends of the rotation center of the locking member, making the locking member form a seesaw shape, which is convenient for pressing to unlock. The unlocking member 6 is located on the upper side of the unlocking part 52. The unlocking end 61 pushes the unlocking part 52 from top to bottom to drive the locking member 5 to rotate, so that the locking part 51 and the anti-detachment part 22 are disengaged.
[0035] Furthermore, the unlocking component 6 includes a pin 63, a compression spring 64, and a nut 65. The pin 63 is vertically installed in a pre-set mounting hole 15 on the housing 1. The lower end of the pin 63 forms an unlocking end 61 and extends into the receiving groove 11. The upper end of the pin 63 is connected to the nut 65 by a thread. A portion of the nut 65 protrudes from the handle 12 and forms a pressing end 62. The middle section of the pin 63 has a shoulder 631, which engages with a pre-set inner ring 151 in the mounting hole 15 to limit the axial displacement of the pin 63, which is the springback height of the pin 63 in this embodiment and returns it to its relative original state. The compression spring 64 is sleeved on the pin 63, with its lower end supporting the housing 1 and its upper end supporting the nut 65. The compression spring 64 provides the pin 63 with an elastic force for automatic reset. When pressed, the spring force of the compression spring 64 is overcome, causing the pin 63 to move downwards. The unlocking end 61 extends into the receiving groove 11 and presses against the unlocking part 52, thereby driving the locking member 5 to rotate, causing the locking part 51 to disengage from the anti-disengagement part 22, thus unlocking the device. When the press is released, the spring force of the compression spring 64 pushes the pin 63 upwards, achieving a reset, ready for the next press. After the pin 63 resets upwards, the unlocking end 61 withdraws from pressing against the unlocking part 52, and the locking member 5 maintains the set locking posture under the support of the second torsion spring 32, causing the locking part 51 to engage with the anti-disengagement part 22. The engagement of the locking part 51 and the anti-disengagement part 22 only restricts the rotation of the pawl in the corresponding direction, while the rotation direction of the pawl is unrestricted when the impact member 4 strikes, allowing the impact member 4 to engage the locking mechanism. When the impactor 4 impacts, the pawl 2 rotates and pushes against the locking member 5. When the impactor 4 slides into the hook 21, the hook 21 receives the impactor 4. The pawl 2 rotates back to its original position and maintains the set locking posture. The locking member 5 also maintains the set locking posture under the support of the second torsion spring 32, thereby capturing the impactor to establish the door lock state.
[0036] The handle lock provided by this utility model has both a handle gripping function and a function of capturing the impacting part with a claw to establish a locking connection. It also introduces an unlocking part, which can be unlocked by pressing, making it easy and convenient. The overall structure is simple and compact, which is convenient to manufacture and assemble. It can be applied to medical equipment, semiconductor equipment, small test chambers, constant temperature and humidity chambers, etc., and has strong practicality and versatility.
[0037] While the preferred embodiments of the present invention have been described above in conjunction with the accompanying drawings, the present invention should not be limited to the same structure and operation as described above and the accompanying drawings. For those skilled in the art, many equivalent improvements and variations can be made to the above embodiments through logical analysis, reasoning or limited experiments without exceeding the concept and scope of the present invention, but these improvements and variations should all fall within the scope of protection claimed by the present invention.
