[0031] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0032] This specific embodiment is a push-button type self-locking quick clamp, the structural diagram of which is shown below. Figures 1-6 As shown.

[0033] Example 1

[0034] The push-button type self-locking quick clamp includes a quick clamp 1, a lock seat 2, and a self-locking mechanism 3. The lock seat 2 is fixedly installed on the quick clamp 1, and the self-locking mechanism 3 is installed on the lock seat 2. The self-locking mechanism 3 is used to keep the quick clamp 1 in a locked state after it is pressed and locked.

[0035] By setting a self-locking mechanism 3, this utility model can keep the quick clamp 1 locked after it is pressed and locked, and the self-locking mechanism 3 can press against the handle of the quick clamp 1, so that the handle of the quick clamp 1 cannot move. This allows the quick clamp 1 to clamp the product, thereby avoiding the risk of the product during processing.

[0036] The self-locking mechanism 3 includes a sliding rod 301 slidably installed inside the lock seat 2, a spring 302 sleeved on the sliding rod 301, a pull rod 303 installed at one end of the sliding rod 301, an extension rod 304 fixedly installed at the other end of the sliding rod 301, and a pressure rod 305 installed on the extension rod 304 for locking the quick clamp 1.

[0037] The lock base 2 has a cavity 201 and a through groove 202 that communicates with the cavity 201.

[0038] The sliding rod 301 and the extension rod 304 are slidably installed inside the cavity 201 and the through groove 202. The outer surface of the pull rod 303 is fixedly connected with an external thread, and the cavity 201 is fixedly installed with an internal thread that mates with the external thread. The pull rod 303 is threadedly installed inside the cavity 201. Through the engagement of the external thread and the internal thread, the pull rod 303 can move inside the cavity 201 when it is rotated.

[0039] A handle 306 is fixedly installed at the end of the pull rod 303 away from the sliding rod 301. The handle 306 facilitates the rotation of the pull rod 303.

[0040] When the handle 306 is rotated clockwise, the pull rod 303 is threaded inside the cavity 201. When the pull rod 303 is rotated clockwise, it can move towards the quick clamp 1. During the movement, the pull rod 303 can drive the sliding rod 301 and the extension rod 304 to move towards the quick clamp 1 inside the cavity 201 and the through groove 202. The extension rod 304 drives the pressure rod 305 to move towards the quick clamp 1.

[0041] Similarly, when the handle 306 is rotated counterclockwise, the lever 303 is moved away from the quick clamp 1.

[0042] The lock seat 2 is provided with a guide mechanism for supporting and guiding the sliding rod 301; the guide mechanism includes a guide block 307 fixedly installed on the sliding rod 301 and a guide groove 203 formed on the lock seat 2 to cooperate with the guide block 307;

[0043] During the sliding process, the sliding rod 301 drives the guide block 307 to slide inside the guide groove 203 opened in the lock seat 2. With the cooperation of the guide block 307 and the guide groove 203, it can not only guide the movement of the sliding rod 301, but also support the sliding rod 301.

[0044] The extension rod 304 has a threaded hole at the end away from the sliding rod 301, and the pressure rod 305 is threadedly connected to the extension rod 304.

[0045] When the lever 303 is rotated clockwise, the pressure lever 305 is moved toward the quick clamp 1. When the pressure lever 305 moves to the position corresponding to the pressure handle of the quick clamp 1, since the pressure lever 305 is threaded to the extension rod 304, rotating the pressure lever 305 clockwise will cause the pressure lever 305 to move toward the pressure handle of the quick clamp 1 until the pressure lever 305 presses against the pressure handle of the quick clamp 1. Under the action of the pressure lever 305, the pressure handle of the quick clamp 1 can be kept locked.

[0046] When the quick clamp 1 no longer needs to be locked, first rotate the pressure lever 305 counterclockwise to move the pressure lever 305 away from the pressure handle of the quick clamp 1, and then rotate the pull rod 303 counterclockwise to reset the sliding rod 301, the extension rod 304 and the pressure lever 305.

[0047] Example 2

[0048] The similarities between this embodiment and Embodiment 1 will not be repeated here. The difference between this embodiment and Embodiment 1 is that the self-locking mechanism 3 includes a sliding rod 301 slidably installed inside the lock seat 2, a spring 302 sleeved on the sliding rod 301, a pull rod 303 fixedly installed at one end of the sliding rod 301, an extension rod 304 fixedly installed at the other end of the sliding rod 301, and a pressure rod 305 installed on the extension rod 304 for locking the quick clamp 1.

[0049] Spring 302 is located inside cavity 201. One end of spring 302 contacts one side of pull rod 303, and the other end of spring 302 contacts the inner wall of cavity 201.

[0050] When the quick clamp 1 needs to be kept locked, the lever 303 is pushed towards the quick clamp 1 by the handle 306. As the lever 303 slides inside the cavity 201, it drives the sliding rod 301 and the extension rod 304 to move synchronously towards the quick clamp 1. The sliding rod 301 drives the guide block 307 to slide inside the guide groove 203. During the movement of the lever 303 towards the quick clamp 1, the spring 302 is compressed. When the guide block 307 disengages from the guide groove 203, it rotates 90 degrees counterclockwise so that the guide block 307 contacts the lock seat 2, preventing the spring 302 from being locked. Under the restoring force of 2, the pull rod 303, sliding rod 301, extension rod 304 and pressure rod 305 are reset as a whole. When the guide block 307 is disengaged from the guide groove 203, the pressure rod 305 corresponds to the pressure handle of the quick clamp 1. After rotating 90 degrees counterclockwise, the pressure rod 305 changes from the vertical direction to the horizontal direction. Then, rotating the pressure rod 305 clockwise makes the pressure rod 305 press against the pressure handle of the quick clamp 1, so that the pressure handle of the quick clamp 1 cannot move, thus keeping the pressure handle of the quick clamp 1 locked. This allows the quick clamp 1 to clamp the product, thereby avoiding risks to the product during processing.

[0051] When the quick clamp 1 no longer needs to be locked, first rotate the pressure rod 305 counterclockwise to disengage it from the pressure handle of the quick clamp 1. Then, rotate the pull rod 303 clockwise through the handle 306 to rotate the pull rod 303, sliding rod 301, extension rod 304, pressure rod 305, and guide block 307 as a whole by 90 degrees. The pressure rod 305 rotates from a horizontal state to a vertical state. After the guide block 307 rotates 90 degrees, it corresponds to the position of the guide groove 203. At this time, under the restoring force of the spring 302, the pull rod 303 is pushed to move away from the quick clamp 1. The pull rod 303 drives the sliding rod 301, extension rod 304, and pressure rod 305 to move away from the quick clamp 1, thus releasing the lock on the pressure handle of the quick clamp 1.

[0052] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
