[0006] Preferably, the top of the mother body is connected to the coil via a fastener, the coil is surrounded by the outer wall of the top of the lock core, and the lock core is provided with a card slot, and the card slots are distributed at equal intervals on the lock core.

[0007] Preferably, the male body is provided with through holes, the through holes are distributed at equal intervals on the male body, the rollers are connected inside the through holes in an embedded manner, and the rollers are symmetrically distributed inside the through holes.

[0008] Preferably, the inner wall of the matrix is provided with a slide groove, and the slide grooves are distributed at equal intervals on the inner wall of the matrix. The slide grooves fit the rollers, and the rollers are slidably connected to the slide grooves.

[0009] Preferably, the roller fits into the slot, the slot is connected to the roller by snapping, and the slot fits into the through hole.

[0010] Preferably, the male body is slidably connected to the inside of the female body, and the bottom of the male body passes through the bottom of the female body and is located outside the female body.

[0011] Preferably, S1: a row of rollers is arranged on one side of the center line of the male body. Rollers of the same size correspond to a smaller male body diameter, which ultimately leads to a decrease in the strength of the male body.

[0012] S2: Or when the male body diameter is the same, the required roller diameter volume is larger, which will result in a reduction in the effective load-bearing portion of the male body;

[0013] S3: Therefore, two or more rows of rollers are set on both sides of the center line of the male body. In this way, the diameter of the multiple rows of rollers will be greatly reduced, and the relative diameter of the male body can be much larger.

Under the action of the coil, the lock core moves downward under the action of the pressure spring, and the lock core slot moves to one side of the roller, so that the roller has space to move. Under the action of external force, the male body is pushed to the middle by the inner wall of the female body. Since the male body and the female body lose the roller locking effect, the male body is separated from the original position of the female body for a distance or completely separated under the action of external force. When it needs to be locked again, the above steps can be repeated in reverse to restore the positions of each component to the locked state, so as to achieve the effect of fast connection and disconnection of the connection structure, which is simple and fast.

[0027] See also Figure 1-9 , a mechanical connection structure and a method for increasing its connection strength, comprising a male body 2, a female body 1 and a lock core 3, characterized in that: a male body 2 is provided inside the female body 1, a lock core 3 is provided inside the male body 2, the top of the lock core 3 passes through the top of the male body 2, the lock core 3 passes through the top of the female body 1, the lock core 3 is slidably connected to the male body 2 and the inside of the female body 1, a roller 6 is provided inside the male body 2, a pressure spring 5 is provided on the inner wall of the top of the female body 1, one end of the pressure spring 5 is connected to the female body 1, and the end of the pressure spring 5 away from the female body 1 is connected to the lock core 3, the male body 2 and the female body 1 are respectively fixed on the equipment to be used, under the action of the coil 4, the lock core 3 does not move, the connecting device is in a locked state, the roller 6 cannot move under the blocking action of the lock core 3 slot 7, the male body 2 and The mother body 1 is tightly combined, so that the connector is in a locked state. Under the action of the coil 4, the lock core 3 moves downward under the action of the pressure spring 5, and the slot 7 of the lock core 3 moves to one side of the roller 6, so that the roller 6 has space to move. Under the action of external force, the male body 2 is pulled and the roller 6 is pushed toward the middle by the inner wall of the mother body 1. Since the male body 2 and the mother body 1 lose the locking effect of the roller 6, the male body 2 is separated from the original position of the mother body 1 for a distance or completely separated under the action of external force. When it needs to be locked again, just repeat the above steps in reverse to restore the position of each component to the locked state, so as to achieve the effect of fast connection and disconnection of the connection structure, which is simple and fast. At the same time, this device has a simple structure and is easy to maintain and operate.

[0028] Specifically, the top of the mother body 1 is connected to the coil 4 through a fastener, and the coil 4 is surrounded by the outer wall of the top of the lock core 3. The lock core 3 is provided with a card slot 7, and the card slots 7 are distributed on the lock core 3 at equal intervals.

[0029] Through the above technical solution, the coil 4 is used to apply an axial force to the lock core 3, and can also be replaced by a different device capable of applying an axial force as needed.

[0030] Specifically, the male body 2 is provided with through holes 8 , which are distributed at equal intervals on the male body 2 . The rollers 6 are connected to the inside of the through holes 8 in an embedded manner, and the rollers 6 are symmetrically distributed inside the through holes 8 .

[0031] Through the above technical solution, four through holes 8 are respectively opened on the four sides of the male body 2 , and the through holes 8 are distributed on the male body 2 in a vertical manner.

[0032] Specifically, a slide groove 9 is opened on the inner wall of the mother body 1 , and the slide grooves 9 are distributed at equal intervals on the inner wall of the mother body 1 . The slide grooves 9 fit the rollers 6 , and the rollers 6 are slidably connected to the slide grooves 9 .

[0033] Through the above technical solution, the slide groove 9 is in a flared form, and one side of the roller 6 can be embedded in the inside of the slide groove 9. At the same time, when the male body 2 moves, the roller 6 can also move out of the inside of the slide groove 9, and then the inner wall of the mother body 1 will push the roller 6.

[0034] Specifically, the roller 6 fits into the slot 7 , the slot 7 is connected to the roller 6 by snapping, and the slot 7 fits into the through hole 8 .

[0035] Through the above technical solution, one side of the roller 6 can be embedded in the slot 7 of the lock core 3. At the same time, the upper and lower ends of the slot 7 are inclined. When the lock core 3 moves, the lock core 3 can push the roller 6 to move through the slot 7.

[0036] Specifically, the male body 2 is slidably connected to the inside of the female body 1 , and the bottom of the male body 2 passes through the bottom of the female body 1 and is located outside the female body 1 .

[0037] Through the above technical solution, the device for controlling the movement and position of the lock core 3 can be the coil 4 or any device that applies axial force to the lock core 3 .

[0038] Specifically, S1: a row of rollers 6 are arranged on one side of the center line of the male body 2. The rollers 6 of the same size correspond to a smaller diameter of the male body 2, which ultimately results in a decrease in the strength of the male body 2.

[0039] S2: Or in the case of the same diameter of the male body 2, the diameter and volume of the roller 6 need to be larger, which will result in a reduction in the effective load-bearing portion of the male body 2;

[0040] S3: Therefore, two rows or even more rows (2-4 rows) of rollers 6 are set on both sides of the center line of the male body 2. In this way, the diameter of the multiple rows of rollers 6 will be greatly reduced, and the diameter of the male body 2 can be much larger relative to the diameter of the male body 2. Under the condition of the same material, the strength will be correspondingly increased.

[0041] Through the above technical solution, the shape of the roller 6 can be replaced with a spherical or cylindrical shape as needed. When the roller 6 is a ball, two rollers 6 are placed inside each through hole 8 of the male body 2.

[0042] When in use, first fix the male body 2 and the female body 1 on the equipment to be used respectively. Under the action of the coil 4, the lock core 3 does not move, the connecting device is in a locked state, and the roller 6 cannot move under the blocking effect of the lock core 3 slot 7. The male body 2 is tightly combined with the female body 1, so that the connector is in a locked state. Under the action of the coil 4, the lock core 3 moves downward under the action of the pressure spring 5, and the slot 7 of the lock core 3 moves to the side of the roller 6, so that the roller 6 has space to move. Under the action of external force, the male body 2 is pulled and the roller 6 is pushed to the middle by the inner wall of the female body 1. Since the male body 2 and the female body 1 lose the locking effect of the roller 6, the male body 2 is separated from the original position of the female body 1 for a distance or completely separated under the action of external force. When it needs to be locked again, just repeat the above steps in reverse to restore the positions of each component to the locked state, and the work can be completed.
