Description

Technical Field

[0001] This utility model relates to a clamp, specifically an active locking clamp. Background Technology

[0002] Existing pipe clamps mainly include bolt-fixed and clamp-type types, and are primarily used in:

[0003] 1. Electronics Industry: In the production of finished electronic products, such as televisions, radios, and DVDs, quick-release clamps are needed for the insertion, mounting, and testing of circuit boards. In addition, these clamps are also used in the production of wiring harnesses for electronic products, equipment, and household appliances.

[0004] 2. Pipeline Repair and Maintenance: Quick-locking pipe clamps are particularly suitable for localized repair and maintenance of pipeline systems. Whether the pipe is small or large diameter, a tight fit and seal can be achieved through the quick-locking mechanism, thereby restoring the pipeline to its normal function.

[0005] 3. Other industrial sectors: Quick-closing pipe clamps can be useful in any workstation involving mass production and requiring positioning and clamping. For example, they are used in the maintenance of pipelines on motorcycles, bicycles, and unmanned vessels.

[0006] However, these clamps have certain limitations in use, such as cumbersome and time-consuming installation and disassembly processes, and high skill requirements for operators. Therefore, there is a need to propose a quick-to-use active locking clamp for ease of use and adjustment. Utility Model Content

[0007] The purpose of this utility model is to provide an active locking clamp to solve at least one of the above-mentioned problems, thereby overcoming the limitations of the prior art where the clamp disassembly process is cumbersome, time-consuming, and requires high skill levels from the operator. This solution enables the clamp to be used and operated quickly, and the operator can lock and unlock it by simply pressing.

[0008] The objective of this utility model is achieved through the following technical solution:

[0009] An active locking clamp includes a base, a pressure lever, and a locking rod;

[0010] The middle part of the pressure lever is movably connected to the base via a third pin; the front part of the pressure lever has a hole structure.

[0011] The tail of the locking rod is movably connected to the base via a second pin; the tail of the locking rod is connected to the hole structure via a first pin; the pressure lever is connected to the first pin via the hole structure, thereby realizing the transmission connection between the pressure lever and the locking rod.

[0012] Preferably, the hole structure is a strip hole, and the first pin is slidably fitted with the strip hole;

[0013] When the clamp is in the locked state, the first pin is located inside the slot at the end away from the third pin.

[0014] When the fixture is not locked, the first pin is located inside the slot near the end of the third pin.

[0015] When the clamp switches between the locked and unlocked states, the first pin slides inside the slot and drives the locking rod to rotate around the second pin.

[0016] Preferably, the clamp further includes a locking latch and an unlocking lever;

[0017] The tail of the locking buckle is connected to the inside of the base through an elastic element; the tail of the pressure lever is provided with a limiting groove for extending into the front of the locking buckle; when the clamp is in the locked state, the locking buckle extends into the limiting groove of the pressure lever; when the clamp is in the unlocked state, the locking buckle separates from the limiting groove of the pressure lever.

[0018] The unlocking rod slides into the base, with the tail of the unlocking rod extending out of the base and the front of the unlocking rod facing the front of the locking buckle; the unlocking rod is used to press the front of the locking buckle to retract the locking buckle.

[0019] Preferably, the front part of the locking buckle is configured as a first inclined surface, and the front part of the unlocking rod is configured as a second inclined surface; by pushing the unlocking rod into the base, the second inclined surface presses against the first inclined surface, thereby pushing the locking buckle to press against the elastic element, and realizing the separation of the locking buckle from the limiting groove of the pressure lever.

[0020] Preferably, the first inclined plane is parallel to the second inclined plane.

[0021] Preferably, the elastic element is a spring.

[0025] Preferably, the clamp is in a locked state, and the base, pressure lever, and locking rod form an arc.

[0026] The working principle of this utility model is as follows:

[0027] In use, by pressing the tail of the lever, the lever rotates around the third pin, and through the cooperation between the first pin and the hole structure, it drives the locking rod to rotate around the second pin, thereby realizing the unlocking and locking of the active locking clamp.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. Convenient installation and disassembly: The double lever mechanism between the base, pressure lever and locking rod enables quick fixing and disassembly of the clamp. The clamp can be locked and unlocked by simply pressing the pressure lever or unlocking rod, improving the convenience of equipment inspection, maintenance and debugging.

[0030] 2. Excellent locking capability: The locking buckle design ensures that the locking structure with locking rod will not be accidentally opened or fail to hold due to external environmental factors when locked.

[0031] 3. Lower cost and maintenance difficulty: With a simple and reliable mechanical structure, it has a longer lifespan compared to clamps that require manual disassembly. Attached Figure Description

[0037] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0038] Example

[0039] An active locking clamp, such as Figure 1-4 As shown, it includes a base, a pressure lever 3, and a locking lever 4;

[0040] The middle part of the pressure lever 3 is movably connected to the base via a third pin 9; the front part of the pressure lever 3 is provided with a hole structure 10;

[0041] The tail of the locking rod 4 is movably connected to the base via the second pin 8; the tail of the locking rod 4 is connected to the hole structure 10 via the first pin 7; the pressure lever 3 is connected to the first pin 7 via the hole structure 10, thereby realizing the transmission connection between the pressure lever 3 and the locking rod 4.

[0042] More specifically, in this embodiment:

[0043] This active locking clamp, such as Figure 1-4 Specifically, it includes a base, a pressure lever 3, a locking lever 4, a locking buckle 5, and an unlocking lever 6.

[0044] The base includes an upper base 2 and a lower base 1, which together form a semi-circular or nearly semi-circular annular cylindrical cavity. The pressure lever 3, locking rod 4, locking buckle 5, and unlocking rod 6 are located inside this cavity. The locking rod 4 extends from the front end of the base, and the unlocking rod 6 extends from the side of the base. Furthermore, the middle part of the base and its inner wall surface are provided with an extension hole to accommodate the extension of the pressure lever 3, allowing the clamp to apply pressure to the pressure lever 3 and drive its rotation when an object is inserted. A dovetail groove is provided at the rear of the base for connecting the clamp to an external structure.

[0045] The lever 3 is connected to the base at its middle position via a third pin 9, and the lever 3 can rotate around the third pin 9; a limit groove is provided at the tail of the lever 3 to receive the locking latch 5 to lock the lever 3 when it is rotated to the locked position; a hole structure 10 is provided at the front of the lever 3, specifically, as shown in the figure. Figure 3 As shown, the hole structure 10 is a strip hole.

[0046] A pair of locking rods 4 are provided, located on the upper and lower sides of the pressure lever 3 respectively. The locking rods 4 are connected to the base at their tail (near the front of the pressure lever 3) via a second pin 8, allowing the locking rods 4 to rotate around the second pin 8. Furthermore, the locking rods 4 also have a first pin 7 at their tail, which extends into a sliding fit within a hole structure 10 at the front of the pressure lever 3. Therefore, when the pressure lever 3 rotates, the movement of this hole structure 10 will cause the first pin 7 and the locking rods 4 to move (rotate), realizing the transmission between the pressure lever 3 and the locking rods 4. The locking rods 4 extend from the front end of the base, as shown... Figure 3 As shown, in the locked state, the base, pressure lever 3, and locking rod 4 together form a superior arc, specifically a 3 / 4 circle, to achieve a stable lock on the pipe contained therein.

[0047] The locking buckle 5 is assembled inside the base. Specifically, it is movably assembled inside the base via an elastic element (spring) and located at the tail of the pressure lever 3. When the pressure lever 3 is in the locked position, the locking buckle 5 extends into the limiting groove under the elastic force of the spring. The tail of the locking buckle 5 is connected to the inside of the base via a spring (the base is designed with an internal space to fully accommodate the locking buckle 5 and the spring, so that the pressure lever 3 can rotate flexibly in the non-locked state, at which time the front end of the locking buckle 5 abuts against the outer surface of the pressure lever 3). Its front part is designed as a slope (first slope) for cooperating with the unlocking rod 6.

[0048] Unlock lever 6, as Figure 4 As shown, it is located on the side of the base and slides with the base. The tail of the unlocking rod 6 extends out of the base and can be pushed in by external force; the front of the unlocking rod 6 is designed as a slope (second slope), which is opposite to the first slope of the locking buckle 5; a protruding ring is provided in the middle of the unlocking rod 6 to form a limit with the base, preventing the unlocking rod 6 from being pulled out directly from its interior. The unlocking rod 6 and the locking buckle 5 are arranged perpendicularly, and the front of the unlocking rod 6 is specifically a triangular prism structure, with the second slope parallel to the first slope (having the same slope), and the right angle surface abutting the outer wall of the pressure lever 3 (in the locked state). Then, by pushing the unlocking rod 6 into the base, the second slope presses against the first slope to apply pressure to the locking buckle 5, causing the locking buckle 5 to retract. When the unlocking rod 6 is fully pushed in, the locking buckle 5 separates from the limiting groove, and the pressure lever 3 regains its mobility, realizing the unlocking of the pressure lever 3.

[0049] When using this active locking clamp: Place the object to be locked against the inner surface of the base. The object will directly push the tail of the pressure lever 3, causing the pressure lever 3 to rotate around the third pin 9. This, in turn, through the cooperation of the hole structure 10 and the first pin 7, drives the locking rod 4 to rotate around the second pin 8 towards the base, thus locking. When the pressure lever 3 is pushed into the locked state (fully retracted into the base), the locking buckle 5 is not blocked by the tail wall of the pressure lever 3. Therefore, under the action of the spring, the locking buckle 5 extends into the limiting groove at the tail of the pressure lever 3 to lock the pressure lever 3. When unlocking is required, push the unlocking rod 6 into the base. Under the squeezing action of the second inclined surface against the first inclined surface, the locking buckle 5 disengages from the limiting groove and is pressed back into the internal space of the base. At this point, the pressure lever 3 is unlocked. Subsequently, the clamp or the object can be removed, and all structures can be reset.

[0050] The above description of the embodiments is provided to enable those skilled in the art to understand and use the utility model. It will be apparent to those skilled in the art that various modifications can be easily made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present utility model is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present utility model without departing from its scope should be within the protection scope of the present utility model.
