[0051] like Figure 1-Figure 8 As shown, an embodiment of the present invention provides a connection locking mechanism, comprising:

[0056] A connecting column 4, the upper portion of which is connected to the driving end of the electric tool; the bottom of which is threadedly connected to the upper portion of the inner cavity of the locking sleeve 2;

[0057] The pressure applying part 5 is connected to the connecting column 4 , and the pressure applying part 5 is rotatably connected to the pressure sleeve 3 .

[0058] In this embodiment, when the first device 6 and the second device 7 need to be locked, a power hand hook is used to hoist the power tool above the connection locking mechanism, so that the power tool is lowered until the driving end of the power tool is connected to the upper part of the connecting column 4, and the internal motor of the power tool is started, thereby driving the power tool connector to rotate clockwise relative to the locking sleeve 2, and utilizing the threaded connection between the bottom of the connecting column 4 and the upper part of the inner cavity of the locking sleeve 2 to realize the lowering of the connecting column 4, and the pressure-applying portion 5 descends with the connecting column 4 and drives the pressure-applying sleeve 3 to vertically descend relative to the locking sleeve 2, so that the conical cavity 32 contacts the multiple steel balls 23, and the ends of the multiple steel balls 23 are pushed through the multiple exposed holes 22 and stuck in the multiple locking grooves 11, thereby realizing the first device 6 and the second Locking of device 7; when the first device 6 needs to be separated from the second device 7, use a power hand hook to hoist the power tool above the connection locking mechanism, and lower the power tool until the driving end of the power tool is connected to the upper part of the connecting column 4, start the internal motor of the power tool, and then drive the power tool connecting head to rotate counterclockwise relative to the locking sleeve 2, and use the threaded connection between the bottom of the connecting column 4 and the upper part of the inner cavity of the locking sleeve 2 to make the connecting column 4 rise, and the pressure-applying part 5 rises with the connecting column 4 and drives the pressure-applying sleeve 3 to rise vertically relative to the locking sleeve 2; the conical cavity 32 is disengaged from the multiple steel balls 23, and the multiple steel balls 23 lose the extrusion force and disengage from the locking groove 11, thereby realizing the unlocking of the first device 6 and the second device 7.

[0059] The present invention needs to realize the disassembly, assembly and tightening operations of the first device 6 and the second device 7 in the hot chamber, modularize the structure of the connecting locking mechanism, and disassemble it into a connecting column 4, a pressure-applying part 5, a pressure-applying sleeve 3, a locking sleeve 2 and a locking vertical rod 1 that are connected and matched with each other, wherein the pressure-applying part 5 is connected to the connecting column 4, the pressure-applying part 5 is rotatably connected to the pressure-applying sleeve 3, the pressure-applying sleeve 3 is slidably connected to the outer side of the locking sleeve 2, and the above-mentioned components are connected to the first device 6 through the bottom of the locking sleeve 2; the bottom of the locking vertical rod 1 is connected to the second device 7, and at the same time, the upper part of the locking vertical rod 1 passes through the first device 6 and is slidably connected to the locking sleeve 2, and through the connection and cooperation between the components, the precise positioning between the first device 6 and the second device 7 is realized in disguise.

[0060] The upper part of the connecting column 4 is formed with a hexagonal joint, which is connected to the driving end of the electric tool. The electric tool is used to provide rotational power and can change the direction freely. The lower part of the connecting column 4 is formed with an external thread. The mechanical characteristics of the threaded connection can change the direction of the force to convert the rotational stress into the axial stress. The pressure part 5 is arranged on the connecting column 4 to follow the tightening or loosening of the thread to synchronize the circular motion and the axial motion. The pressure part 5 is rotatably connected to the pressure sleeve 3 to offset the rotational motion of the pressure part 5 and only retain the motion in the axial stress direction.

[0061] The locking sleeve 2 adopts the locking method of steel balls 23, and provides a large bearing capacity through the squeezing and locking action of the steel balls 23, thereby ensuring the stability and reliability of the connecting piece. In the locked state, the steel balls 23 can be evenly distributed on the contact surface of the connecting piece to form a stable locking force, thereby improving the rigidity and centering of the connecting piece, and further improving the accuracy of the device installation.

[0062] An avoidance cavity 31 is formed at the bottom of the inner cavity of the pressure sleeve 3, and the inner wall of the avoidance cavity 31 is away from the outer wall of the locking sleeve 2. The avoidance cavity 31 is used to block and limit the steel ball 23. A conical cavity 32 is formed between the avoidance cavity 31 and the inner cavity of the pressure sleeve 3. The conical surface of the inner wall of the conical cavity 32 is used to squeeze and push the ends of multiple steel balls 23 through multiple exposure holes 22 and get stuck in multiple locking grooves 11 when the pressure sleeve 3 descends, thereby achieving a locking effect. In summary, the present invention omits the positioning process by modularly arranging the fastening mechanism in the equipment, thereby solving the technical problem of low fastening effect caused by long-distance operation in the hot chamber.

[0063] like Figure 1 , Figure 3 , Figure 5 and Figure 7 As shown in FIG. 1 , in an optional embodiment of the present invention, the pressure applying portion 5 comprises:

[0064] A lower pressing plate 41, wherein the lower pressing plate 41 is formed on a side wall of the connecting column 4;

[0065] A first clamping ring 33, wherein the first clamping ring 33 is formed at the top of the inner cavity of the pressure sleeve 3;

[0066] A second snap ring 34, wherein the second snap ring 34 is formed at the top of the inner cavity of the pressure sleeve 3, the second snap ring 34 is located below the first snap ring 33, and the inner diameter of the second snap ring 34 is greater than the inner diameter of the first snap ring 33;

[0067] A shaft sleeve cover 51, wherein the shaft sleeve cover 51 is connected to the bottom surface of the lower pressure plate 41, the bottom surface of the shaft sleeve cover 51 abuts against the upper surface of the pressure sleeve 3, and the connecting column 4 passes through a first through hole 511 in the center of the shaft sleeve cover 51;

[0068] A third snap ring 52, wherein the connecting column 4 passes through a second through hole 521 in the center of the third snap ring 52, the third snap ring 52 is connected to the bottom surface of the shaft sleeve cover 51, and the third snap ring 52 is located inside the first snap ring 33;

[0069] The fourth snap ring 53, the connecting column 4 passes through the third through hole 531 in the center of the fourth snap ring 53, the fourth snap ring 53 is formed on the bottom surface of the third snap ring 52, the fourth snap ring 53 is located in the second snap ring 34, and the bottom surface of the first snap ring 33 is in contact with the top surface of the fourth snap ring 53.

[0070] In this embodiment, when the first device 6 and the second device 7 need to be locked, the connecting column 4 is rotated clockwise, and the threaded connection between the bottom of the connecting column 4 and the upper part of the inner cavity of the locking sleeve 2 is utilized to realize the lowering of the connecting column 4. The lower pressure plate 41 descends with the connecting column 4 and pushes the pressure sleeve 3 to move downward through the shaft sleeve cover 51. When the first device 6 and the second device 7 need to be unlocked, the connecting column 4 is rotated counterclockwise, and the threaded connection between the bottom of the connecting column 4 and the upper part of the inner cavity of the locking sleeve 2 is utilized to realize the rising of the connecting column 4. The fourth retaining ring 53 rises with the connecting column 4 and drives the first retaining ring 33 to rise, so as to pull the pressure sleeve 3 to move upward.

[0071] The lower pressing plate 41 is formed on the outer side of the connecting column 4 to rotate synchronously with the connecting column 4. The bottom surface of the lower pressing plate 41 abuts against the top surface of the shaft sleeve cover 51. The first clamping ring 33 is formed on the top of the pressure sleeve 3 to assist in pushing the pressure sleeve 3 to move downward, thereby squeezing the steel ball 23 inward to achieve the locking of the mechanism.

[0072] The shaft sleeve cover 51 is disposed between the lower pressure plate 41 and the first retaining ring 33. On the one hand, it is used to push the first retaining ring 33 downward under force, and on the other hand, it provides a seal for the upper part of the pressure sleeve 3. The center of the shaft sleeve cover 51 is provided with a first through hole 511. The first through hole 511 is used to penetrate and connect the connecting column 4, thereby improving the positioning accuracy of the device.

[0073] The first snap ring 33 and the second snap ring 34 are both formed on the top of the pressure sleeve 3, wherein the inner diameter of the second snap ring 34 is larger than the inner diameter of the first snap ring 33, and the second snap ring 34 is located below the first snap ring 33, so the two form a first stepped structure with a larger upper portion and a smaller lower portion on the top of the pressure sleeve 3, and the top of the pressure sleeve 3 is kept horizontal to fit closely with the shaft sleeve cover 51 to increase the force bearing area;

[0074] Correspondingly, the second through hole 521 and the third through hole 531 are respectively formed at the center of the third clamping ring 52 and the fourth clamping ring 53, and the connecting column 4 passes through the first through hole 511, the second through hole 521 and the third through hole 531 in sequence. The connecting column 4 is subjected to triple positioning calibration, which further improves the positioning accuracy of the device;

[0075] In terms of position, the third retaining ring 52 is connected to the bottom surface of the shaft sleeve cover 51, and the third retaining ring 52 is located in the first retaining ring 33. The fourth retaining ring 53 is formed on the bottom surface of the third retaining ring 52, and the fourth retaining ring 53 is located in the second retaining ring 34. The two correspondingly form a second step structure with a small upper part and a large lower part. The bottom surface of the first retaining ring 33 abuts against the top surface of the fourth retaining ring 53 to pull the pressure sleeve 3 to move upward, thereby returning the position of the steel ball 23 to the avoidance cavity 31, thereby realizing the locking release of the mechanism, and further improving the reliability of the connection locking mechanism.

[0076] like Figure 5 As shown, in an optional embodiment of the present invention, the lower pressure plate 41 is detachably connected to the shaft sleeve cover 51 via a first bolt 54 , and the shaft sleeve cover 51 is detachably connected to the third retaining ring 52 and the fourth retaining ring 53 via a second bolt 55 .

[0077] In this embodiment, in terms of connection, the lower pressure plate 41 is detachably connected to the shaft sleeve cover 51 through a first bolt 54, and the shaft sleeve cover 51 is detachably connected to the third retaining ring 52 and the fourth retaining ring 53 through a second bolt 55. On the one hand, the detachable connection structure is convenient for the inspection and replacement of parts. On the other hand, the connection path does not include the pressure sleeve 3, and the connecting column 4, the shaft sleeve cover 51, the third retaining ring 52 and the fourth retaining ring 53 form a whole to ensure the rotational connection with the pressure sleeve 3, so that the pressure sleeve 3 only moves up and down in the axial direction, thereby improving the operating stability of the connection locking mechanism.

[0078] like Figure 8 As shown, in an optional embodiment of the present invention, it also includes:

[0079] The mounting groove 71 is opened on the surface of the second device 7 , and a mounting side plate 12 is formed at the bottom of the locking vertical rod 1 . The mounting side plate 12 is installed in the mounting groove 71 by fastening bolts, and the upper surface of the mounting side plate 12 abuts against the second device 7 .

[0080] In this embodiment, the mounting groove 71 is arranged inside the second device 7 to place the mounting side plate 12. The mounting side plate 12 is installed in the mounting groove 71 by fastening bolts to position the locking vertical rod 1, and further accurately position the first device 6 and the second device 7. The upper surface of the mounting side plate 12 corresponds to the surface of the second device 7, so that the first device 6 and the second device 7 are tightly fitted, reducing working errors.

[0081] like Figure 1 , Figure 3 and Figure 6 As shown, in an optional embodiment of the present invention, it further includes: a connecting plate 8, the top surface of the connecting plate 8 is detachably connected to the bottom surface of the locking sleeve 2 through a fastening bolt, the bottom surface of the connecting plate 8 is detachably connected to the first device 6 through a fastening bolt, a fourth through hole 81 is formed on the surface of the connecting plate 8, and a fifth through hole 61 is formed on the first device 6;

[0082] The locking vertical rod 1 passes through the fifth through hole 61 and the fourth through hole 81 in sequence.

[0083] In this embodiment, the connecting plate 8 is arranged between the locking sleeve 2 and the first device 6, and is used as a buffer connection to prevent the pressure sleeve 3 from directly contacting the first device 6, thereby reducing mechanical damage and extending the service life. In addition, a fourth through hole 81 is provided on the surface of the connecting plate 8, and a fifth through hole 61 is provided on the first device 6. The locking vertical rod 1 passes through the fifth through hole 61 and the fourth through hole 81 in sequence and is slidably connected to the pressure sleeve 3. While the connecting plate 8 plays a connecting role, the axial position consistency of the fourth through hole 81 and the fifth through hole 61 improves the positioning accuracy and further increases the reliability of the device operation.

[0084] Preferably, a mounting boss is formed above the mounting side plate 12, and the mounting boss passes through the five through holes 61 of the first device 6. The diameter of the mounting boss is greater than the diameter of the locking vertical rod 1, so as to ensure the consistency of the axial positions of the fourth through hole 81 and the fifth through hole 61, and to achieve the abutment between the connecting plate 8 and the top surface of the mounting boss, thereby further improving the connection strength and the positioning accuracy.

[0085] like Figure 1 , Figure 3 and Figure 7 As shown, in an optional embodiment of the present invention, it also includes:

[0086] A fixing seat 9, wherein the fixing seat 9 is connected to the top surface of the pressure sleeve 3 by means of a fastening bolt, and the driving end of the electric tool abuts against the top surface of the fixing seat 9;

[0087] The edge of the fixing seat 9 is formed with a guide block 91 , and the guide block 91 is formed with a guide fillet 911 inwardly.

[0088] In this embodiment, the driving end of the power tool needs to be connected to the upper part of the connecting column 4 to drive the connecting column 4 to rotate synchronously. Preferably, the upper part of the connecting column 4 adopts a hexagonal joint to adapt to different access angles and has good stability and sealing. The fixing seat 9 is used to provide a bearing plane for the driving end of the power tool. The edge of the fixing seat 9 is formed with a guide block 91, and the guide block 91 further limits the driving end of the power tool to ensure that the driving end of the power tool is accurately plugged and connected to the connecting column 4. The guide fillet 911 formed inwardly on the guide block 91 is used for simple disassembly and replacement, which reduces the rigid collision between components and further improves the reliability of the operation of the device.

[0092] The positioning pin 25 is threadedly connected to the blind hole 24 , and the positioning pin 25 is slidably matched with the long slot 35 .

[0093] In this embodiment, the pressure sleeve 3 can be limited by the sliding cooperation between the positioning pin 25 and the long slot 35 to prevent the pressure sleeve 3 from rotating, so that the pressure sleeve 3 is driven by the pressure portion 5 to descend or rise relative to the locking sleeve 2, further achieving locking and contact locking, and ensuring smooth connection and locking; at the same time, the positioning pin 25 and the long slot 35 are used to limit the pressure sleeve 3 to prevent the pressure sleeve 3 from being separated from the locking sleeve 2 when rising;

[0094] The locating pin 25 is threadedly connected to the blind hole 24, which facilitates the installation and disassembly of the pressure sleeve 3 and the locking sleeve 2, thereby facilitating the installation and disassembly of the entire connection locking mechanism, thereby facilitating the maintenance or component replacement of the connection locking mechanism.

[0096] In this embodiment, the positioning pin 25 and the steel ball 23 are arranged on the locking sleeve 2, and the long groove 35 and the avoidance cavity 31 are arranged on the pressure sleeve 3. The relative position relationship between the positioning pin 25 and the long groove 35 is limited to define the relative position relationship between the steel ball 23 and the avoidance cavity 31. When the positioning pin 25 is located at the bottom of the long groove 35, the steel ball 23 corresponds to the avoidance cavity 31. At this time, the device is in a locking release state, so as to realize that the steel ball 25 is separated from the locking groove 11 without separating from the accommodating cavity 21; when the device is in a locked state, the positioning pin 25 is away from the bottom of the long groove 35. At this time, the steel ball 23 corresponds to the tapered cavity 32, thereby ensuring the locking effect of the device and further improving the reliability of the device.

[0097] like Figure 1-Figure 4 and Figure 7As shown, in an optional embodiment of the present invention, the avoidance cavity 31 and the tapered cavity 32 have a smooth transition;

[0098] The tapered cavity 32 and the inner cavity of the pressure sleeve 3 have a smooth transition.

[0099] In this embodiment, there is a smooth transition between the avoidance cavity 31 and the conical cavity 32, and there is a smooth transition between the conical cavity 32 and the inner cavity of the pressure sleeve 3, so that the steel ball 23 always maintains contact with the inner wall of the pressure sleeve 3 during the operation of the mechanism, avoiding jamming during movement and further improving the stability of the device operation.

[0100] like Figure 8 As shown, in an optional embodiment of the present invention, the inner wall of the locking groove 11 is a curved surface structure adapted to the steel ball 23 .

[0101] In this embodiment, the inner wall of the locking groove 11 is a curved surface structure adapted to the steel ball 23, so that when the device is relaxed, the steel ball 23 can easily escape with the help of the inclination angle of the curved surface structure, further improving the stability of the device operation.

[0102] In summary, the present invention provides a connection locking mechanism. In the preparation stage, the mounting side plate 12 at the bottom of the locking vertical rod 1 is set in the mounting groove 71 opened on the surface of the second device 7, and the upper surface of the mounting side plate 12 corresponds to the surface of the second device 7; the two sides of the connecting plate 8 are respectively connected to the bottom of the locking sleeve 2 and the first device 6, the connecting column 4 passes through the shaft sleeve cover 51 and the pressure sleeve 3 from the top, and then the third retaining ring 52 and the fourth retaining ring 53 are connected to the shaft sleeve cover 51 from the bottom, the lower pressure plate 41 is detachably connected to the shaft sleeve cover 51 by the first bolt 54, and the shaft sleeve cover 51 is connected to the lower pressure plate 41 by the first bolt 54. The third retaining ring 52 and the fourth retaining ring 53 are detachably connected through the second bolt 55, and the whole is rotatably connected with the pressure sleeve 3; the plurality of steel balls 23 are arranged inside the plurality of accommodating cavities 21 through the exposure hole 22, the lower end of the connecting column 4 is threadedly connected with the upper part of the inner cavity of the locking sleeve 2, the long groove 35 is aligned with the blind hole 24 and the positioning pin 25 is installed; finally, the upper part of the locking vertical rod 1 is sequentially passed through the first device 6, the connecting plate 8 and the lower part of the inner cavity of the locking sleeve 2 until the locking groove 11 corresponds to the accommodating cavity 21, and the fixing seat 9 is connected to the top surface of the pressure sleeve 3 by tightening bolts, and the preparation stage is completed;

[0103] During the working stage, when it is necessary to lock the first device 6 and the second device 7, the power hand hook is used to hoist the power tool above the connection locking mechanism, and the power tool is lowered to be completely placed on the fixing seat 9. The driving end of the power tool is accurately plugged and connected with the upper part of the connecting column 4 through the guiding effect of the fixing seat 9 and the guide block 91, and the internal motor of the power tool is started, thereby driving the power tool connector to rotate clockwise relative to the locking sleeve 2, and utilizing the threaded connection between the bottom of the connecting column 4 and the upper part of the inner cavity of the locking sleeve 2. The connection causes the connecting column 4 to descend. Due to the rotational connection relationship formed between the pressure-applying portion 5 and the pressure-applying sleeve 3, and the limiting and guiding function of the positioning pin 25 and the long groove (35), the pressure-applying portion 5 descends along with the connecting column 4 and drives the pressure-applying sleeve 3 to vertically descend relative to the locking sleeve 2. The conical cavity 32 contacts the plurality of steel balls 23, pushing the ends of the plurality of steel balls 23 to pass through the plurality of exposed holes 22 and get stuck in the plurality of locking grooves 11, thereby achieving the locking of the first device 6 and the second device 7.

[0104] When it is necessary to loosen the first device 6 and the second device 7, use a power hand hook to hoist the power tool above the connection locking mechanism, lower the power tool to be completely placed on the fixing seat 9, and through the guiding effect of the fixing seat 9 and the guide block 91, the driving end of the power tool is accurately plugged and connected with the upper part of the connecting column 4, and the internal motor of the power tool is started, thereby driving the power tool connector to rotate counterclockwise relative to the locking sleeve 2, and utilizing the threaded connection between the bottom of the connecting column 4 and the upper part of the inner cavity of the locking sleeve 2 to make the connecting column 4 rise. Due to the rotational connection relationship formed between the pressure-applying part 5 and the pressure-applying sleeve 3, and the limiting guiding effect of the positioning pin 25 and the long groove 35, the pressure-applying part 5 rises with the connecting column 4 and drives the pressure-applying sleeve 3 to rise vertically relative to the locking sleeve 2; the conical cavity 32 is disengaged from the plurality of steel balls 23, and the plurality of steel balls 23 lose the extrusion force and disengage from the locking groove 11, thereby realizing the release of the lock of the first device 6 and the second device 7.

[0105] By modularizing the fastening mechanism in the equipment, the positioning process is omitted, thus solving the technical problem of low fastening effect caused by long-distance operation in the hot chamber.

[0106] The above are preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
