Description

Technical Field

[0001] This utility model relates to the field of mechanical connection technology, and specifically to a mechanical connection component. Background Technology

[0002] Mechanical connection components, as indispensable parts in modern mechanical equipment, are widely used for connection and transmission between various moving mechanisms. By installing them on two moving parts, stable transmission and relative motion between the two parts are achieved. This allows the parts to rotate, translate, and perform other actions in response to the movement of another part, thereby meeting the requirements for synchronous motion between the parts and improving the overall stability and coordination of operation.

[0003] However, existing mechanical connection assemblies typically use bolts to fix components together. This necessitates the use of tools and significant time for bolt removal and installation when frequent disconnection is required between components or when switching connections with different components. This process is cumbersome and inefficient, and repeated disassembly and reassembly can cause thread wear, affecting connection accuracy and structural strength, ultimately impacting the reliability and lifespan of the connection. Therefore, this invention proposes a mechanical connection assembly that allows for quick connection and disconnection. Summary of the Invention

[0006] Furthermore, the quick-release assembly includes a locking block and a releasing block. The locking block and the releasing block are slidably mounted on the fixing member and the connecting member respectively by a reset spring and a support spring. The connecting member is provided with a limiting groove that cooperates with the locking block and the releasing block.

[0007] Furthermore, guide rods are provided on both sides of the block, and the connector is provided with guide grooves that cooperate with the guide rods.

[0008] Furthermore, one end of the connector is provided with a positioning groove that mates with the fixing member, and one end of the fixing member is provided with a positioning block that mates with the positioning groove.

Detailed Implementation

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0016] In this embodiment, refer to Figure 1 - Figure 4 The mechanical connection assembly specifically implemented includes a connector 1 and a rotating component 2. The rotating component 2 is rotatably mounted on one end of the connector 1, and the other end of the connector 1 is provided with a detachable fixing component 4 via a quick-release assembly 3. Both the rotating component 2 and the fixing component 4 have positioning holes at one end that cooperate with moving parts, for quick positioning and fixing with the moving parts.

[0017] In use, the quick-release assembly 3 separates the connector 1 from the fixing part 4. The fixing part 4 is then installed on the moving part, replacing the direct connection between the connector 1 and the moving part. Subsequently, the rotating part 2 at the other end of the connector 1 is connected and fixed to another moving part. The quick-release assembly 3 then reconnects and locks the fixing part 4 to the connector 1, connecting the two moving parts. Thus, the movement of one moving part drives the other to move synchronously, achieving a linkage effect. When disassembly is required, simply operate the quick-release assembly 3 to release the lock, allowing the fixing part 4 to quickly separate from the connector 1, thereby disconnecting the two moving parts and enabling independent movement.

[0018] In this embodiment, the quick-release assembly 3 includes a locking block 31 and a releasing block 32. The locking block 31 and the releasing block 32 are slidably mounted on the fixing member 4 and the connecting member 1 respectively via a return spring 33 and a support spring 34. The connecting member 1 is provided with a limiting groove 11 that cooperates with the locking block 31 and the releasing block 32. Guide rods 321 are provided on both sides of the releasing block 32, and the connecting member 1 is provided with guide grooves 12 that cooperate with the guide rods 321. The cooperation between the guide rods 321 and the guide grooves 12 ensures that the releasing block 32 remains stable during sliding, avoiding displacement or jamming, thereby ensuring smooth and reliable unlocking action.

[0019] There are two locking blocks 31, two unlocking blocks 32, and two limiting grooves 11, symmetrically arranged on both sides of the fixing member 4 and the connecting member 1. The fixing member 4 is provided with a mounting groove for accommodating the two locking blocks 31. The two locking blocks 31 are respectively installed at both ends of the mounting groove. The return spring 33 is located between the two locking blocks 31 and abuts against them, so that the two locking blocks 31 move away from each other under the action of the return spring 33 and protrude out of the outside of the mounting groove, thereby cooperating with the limiting groove 11 to realize the automatic locking function.

[0020] Two unlocking blocks 32 are slidably installed in two limiting grooves 11 by bolts. A support spring 34 is located between the limiting grooves 11 and the unlocking blocks 32, and abuts against them, allowing the unlocking blocks 32 to slide outward under elastic action, providing space for the locking block 31 to smoothly engage with the limiting grooves 11 and complete the locking. The end of the unlocking block 32 away from the limiting grooves 11 extends radially outward to form a pressing block 322. Two guide rods 321 are integrally formed on both sides of the pressing block 322, so that when the pressing block 322 is subjected to force, it can drive the unlocking block 32 to move smoothly along the sliding direction of the guide rods 321, thereby ensuring smooth unlocking action and avoiding jamming or deflection, which would affect the reliability of the unlocking operation. The outer side of the pressing block 322 is provided with anti-slip texture to increase the friction when the finger applies force, improve the operating feel, and prevent slippage when pressing, ensuring the stability and convenience of the unlocking operation.

[0021] In this embodiment, one end of the connector 1 is provided with a positioning groove 13 that mates with the fixing member 4, and one end of the fixing member 4 is provided with a positioning block 41 that mates with the positioning groove 13. A guide structure 14 that mates with the locking block 31 is provided on one side of the positioning groove 13. Two release blocks 32 and a limiting groove 11 are respectively provided on both sides of the positioning groove 13, and two locking blocks 31 are symmetrically provided on both sides of the positioning block 41.

[0022] The dimensional fit between the positioning groove 13 and the positioning block 41 ensures precise alignment during assembly, guaranteeing the connection accuracy between the connector 1 and the fixing part 4 and preventing shaking or loosening during use.

[0023] In use, the positioning block 41 is aligned with the positioning groove 13 and inserted. Under the guidance of the guide structure 14, the locking block 31 is gradually pressed into the mounting groove, thus preventing interference between the locking block 31 and the edge of the positioning groove 13, which would affect the smooth insertion of the positioning block 41. Once the positioning block 41 is fully inserted into the positioning groove 13, the locking block 31, with the cooperation of the positioning block 41 and the positioning groove 13, is precisely aligned with the limiting groove 11. Under the elastic action of the return spring 33, it automatically pops out and locks into the two limiting grooves 11, thereby achieving a secure lock between the connecting member 1 and the fixing member 4.

[0024] When it is necessary to disconnect the connection between the connector 1 and the fixing part 4, simply press the pressing block 322 of the two release blocks 32 at the same time, so that the two release blocks 32 slide inward and squeeze the locking block 31 to overcome the elastic force of the return spring 33 and retract into the mounting groove, disengaging from the limiting groove 11. At this time, the locking state between the positioning block 41 and the positioning groove 13 is released, and the disassembly can be completed simply by pulling the positioning block 41 out of the positioning groove 13. The operation is simple and quick.

[0025] During installation, simply inserting the positioning block 41 into the positioning slot 13 completes the connection between the connector 1 and the fixing part 4, requiring no additional operation. Disconnection is achieved simply by pressing and pulling the connector 1 and fixing part 4. The entire connection and disconnection process requires no tools, saving time and effort while making the connection and separation between the two components more efficient and convenient, thus improving the overall smoothness of operation and user experience.

[0026] One end of the rotating component 2 is provided with a rotating block 21, and one end of the connecting component 1 is provided with a rotating groove 15 that mates with the rotating block 21. The rotating block 21 is a stepped shaft structure, and the rotating groove 15 is a stepped groove structure that matches the stepped shaft. Through the cooperation of the stepped shaft structure and the stepped groove, the rotating block 21 cannot be disengaged after being embedded in the rotating groove 15, and can only rotate around the axis within the rotating groove 15, thereby realizing the rotational connection between the connecting component 1 and the rotating component 2, while preventing axial loosening of the two during use.

[0027] The rotating block 21 is provided with a plurality of angle limiting holes 22 around its axis, and the connecting member 1 is provided with limiting pins 16 that cooperate with the plurality of angle limiting holes 22. In this embodiment, the plurality of angle limiting holes 22 are divided into three groups, each group corresponding to different rotation angle positions. One group of limiting holes corresponds to rotation positioning of 0°, 120° and 240°, the second group corresponds to rotation positioning of 0°, 90°, 180° and 270°, and the third group corresponds to rotation positioning of 45°, 135°, 225° and 315°.

[0028] Three sets of angle limiting holes 22 are arranged at intervals along the axial direction of the rotating block 21. The connecting part 1 has three threaded holes corresponding to the three sets of angle limiting holes 22. In use, the limiting pin 16 is screwed into the corresponding threaded hole and inserted into the corresponding angle limiting hole 22 to lock the rotating part 2 at a specific angle. This meets the needs of fixed angle use in different application scenarios. When the fixed angle is not needed, simply remove the limiting pin 16 to allow the rotating part 2 to return to a free rotation state, facilitating easy adjustment of the angle.

[0029] The layered design of the three sets of angle limiting holes 22 avoids structural strength reduction or interference problems caused by too many angle limiting holes 22 on the same plane, while facilitating quick and flexible selection of angle settings according to actual needs, and avoiding positioning difficulties caused by overly dense layout of limiting holes.

[0030] The other end of the rotating component 2 is provided with a reference block 23 that mates with the component. The reference block 23 is used to achieve precise positioning with the component, ensuring that the component can move accurately in conjunction with the movement of another component, and avoiding misalignment or poor movement caused by installation errors. The reference block 23 can adopt a concentric, eccentric, cam, or irregular structure design to adapt to the movement trajectory of different components, improve the diversity and adaptability of linkage, and enhance the stability and reliability of positioning.

[0031] The connector 1 consists of two symmetrically arranged connecting blocks 17. Each connecting block 17 has a semi-circular stepped groove at one end. When the two connecting blocks 17 are closed, the two semi-circular stepped grooves join to form a rotating groove 15 to accommodate the rotating block 21. The two connecting blocks 17 are fastened with screws, confining the rotating block 21 within the rotating groove 15, allowing it to rotate only around its axis. This structural design not only achieves stable installation and reliable rotation of the rotating block 21, but also simplifies the machining of the rotating groove 15, thereby reducing production costs and improving assembly efficiency.

[0032] The beneficial effects of this utility model are as follows: by fixing the fixed part 4 and the rotating part 2 to the two moving parts respectively, and by using the quick-release assembly 3 to quickly lock and separate the fixed part 4 and the connecting part 1, the two moving parts can be quickly connected or disconnected without the use of any tools, thereby improving the efficiency of mechanical assembly and disassembly, making the operation more convenient and efficient, and avoiding the problem of thread wear caused by frequent disassembly and assembly, which would affect the reliability and service life of the connection.
