DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] As used herein, the phrases "in one embodiment," "according to one embodiment," "in some embodiments," and the like generally refer to the fact that the particular feature, structure, or characteristic following the phrase may be included in at least one embodiment of the present disclosure. Therefore, a particular feature, structure, or characteristic may be included in more than one embodiment of the present disclosure, so that these phrases do not necessarily refer to the same embodiment. As used herein, the terms "example," "exemplary," and the like are used to "serve as an example, instance, or illustration." Any implementation, aspect, or design described herein as "example" or "exemplary" is not necessarily to be construed as preferred or superior to other implementations, aspects, or designs. On the contrary, the use of the terms "example," "exemplary," and the like is intended to present concepts in a concrete manner.

[0025] After research, it was found that the male and female heads of the disadvantageous equipment of the prior art can be connected by a contact connection method. At this time, it is necessary to align and connect the male and female heads through other components so that they can be aligned and stably connected. For example, the first connecting part and the second connecting part are used to align and connect so that the male and female heads can be aligned and stably connected together. Since it is necessary to maintain a stable connection between the male and female heads, the sizes of the parts used for connection of the first connecting part and the second connecting part are adapted, so that the first connecting part and the second connecting part can be stably connected together. The first connecting part and the second connecting part need to be tightly connected together to maintain the stability of the connection. The size of the column of the second connecting part is almost the same as the size of the jack of the first connecting part, which makes it difficult to insert the second connecting part into the first connecting part, resulting in difficulty in installation.

[0026] However, due to the mismatch in size, the two are difficult to insert when plugged together, making installation difficult.

[0027] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0028] like Figure 1 and Figure 6As shown, at least one disclosed embodiment provides a joint positioning mechanism, comprising: a connecting frame 3, and a first connecting portion 1 arranged on the connecting frame 3; the first connecting portion 1 corresponds to an adapted second connecting portion 2, the second connecting portion 2 is arranged on a connecting plate, and the first connecting portion 1 is suitable for connecting the second connecting portion 2; the second connecting portion 2 comprises: a fixed sleeve 21 and a connecting column 22; one end of the fixed sleeve 21 is a connecting end, which is fixed on the connecting plate, and the other end of the fixed sleeve 21 is open; the connecting column 22 is inserted into the fixed sleeve 21, and the connecting column 22 is connected to the The fixed sleeve 21 is rotatably connected; one end of the connecting column 22 extends from the open mouth of the fixed sleeve 21; the connecting column 22 extends out of the fixed sleeve 21 so that the connecting column 22 can be inserted into the second sleeve 12; the connecting column 22 is suitable for being inserted into the second sleeve 12 of the first connecting part 1, and the connecting column 22 rotates during the insertion process; the first connecting part 1 and the second connecting part 2 are aligned and connected, so that the male and female heads corresponding to the equipment can be aligned and stably connected, and the two can be connected more smoothly and conveniently through rotation during the connection process of the first connecting part 1 and the second connecting part 2.

[0029] like Figure 2 and Figure 3 As shown, in an optional embodiment, a limiting ring 211 is provided on the inner wall of the fixed sleeve 21, and the limiting ring 211 is provided close to the connecting end of the fixed sleeve 21; the connecting column 22 passes through the limiting ring 211, and the outer wall of the connecting column 22 contacts the inner wall of the limiting ring 211; a first ring body 221 is provided on the connecting column 22, and the first ring body 221 is provided between the limiting ring 211 and the connecting end of the fixed sleeve 21, and there is a gap between the outer wall of the first ring body 221 and the inner wall of the fixed sleeve 21; the interior of the fixed sleeve 21 can be divided into two spaces by the limiting ring 211, and lubricating oil can be stored in the space between the limiting ring 211 and the connecting end of the fixed sleeve 21, and the lubricating oil can be lubricated during the process of inserting the connecting column 22 into the second sleeve 12, so as to facilitate the insertion of the connecting column 22.

[0030] In an optional embodiment, a movable sleeve 23 is sleeved on the connecting column 22, and the movable sleeve 23 is located between the outer wall of the connecting column 22 and the inner wall of the fixed sleeve 21; the movable sleeve 23 extends from the open mouth of the fixed sleeve 21; a first spring 231 is provided between the movable sleeve 23 and the side wall of the limiting ring 211; a protrusion 232 is provided on the inner wall of the movable sleeve 23; a spiral groove 222 is provided on the outer wall of the connecting column 22, and the protrusion 232 is located in the spiral groove 222, and the protrusion 232 is slidably connected with the spiral groove 222; the side of the movable sleeve 23 extending out of the fixed sleeve 21 is an inclined surface; when the protrusion 232 slides in the spiral groove 222, it drives the connecting column 22 to rotate ; During the insertion of the connecting column 22, the movable sleeve 23 will slide into the fixed sleeve 21, and during the sliding of the movable sleeve 23, the protrusion 232 will move along the spiral groove 222, so that the connecting column 22 rotates. Rotating the connecting column 22 during the insertion process can facilitate the insertion of the connecting column 22 into the second sleeve 12; when the movable sleeve 23 moves into the fixed sleeve 21, the first spring 231 will be compressed, so that the movable sleeve 23 can be reset through the first spring 231 after the connecting column 22 is pulled out of the second sleeve 12; the movable sleeve 23 does not rotate during the movement, for example, the movable sleeve 23 and the limit ring 211 are connected by the first spring 231 to avoid the rotation of the movable sleeve 23 and ensure the rotation effect of the connecting column 22.

[0031] In an optional embodiment, a plurality of flow channels 223 are provided inside the connecting column 22 along the axial direction of the connecting column 22; a through hole 224 corresponding to the flow channel 223 is provided on the first ring body 221 along the radial direction of the first ring body 221; the through hole 224 is communicated with the corresponding flow channel 223; an oil outlet is provided at the position where the connecting column 22 extends out of the fixed sleeve 21, and the oil outlet corresponds to and is communicated with the flow channel 223; lubricating oil is stored between the inner wall of the connecting end of the limiting ring 211 and the fixed sleeve 21; the lubricating oil stored between the connecting end of the limiting ring 211 and the fixed sleeve 21 enters the flow channel 223 through the through hole 224, and then flows out through the oil outlet Outlet flow channel 223; the flow channel 223 can be tilted downward, that is, the flow channel 223 located at the bottom of the connecting column 22 is tilted downward during the rotation of the connecting column 22, and the flow channel 223 is farther away from the connecting end of the fixed sleeve 21 and is lowered, so that the lubricating oil in the flow channel 223 can flow to the oil outlet, and when the through hole 224 rotates with the first ring body 221, the through hole 224 will rotate to the lower position of the first ring body 221. At this time, the lubricating oil can flow into the flow channel 223 through the through hole 224, and then flow along the inclined flow channel 223 to the oil outlet, and then flow out of the oil outlet. During the process of inserting the connecting column 22 into the second sleeve 12, the connecting column 22 can be slowly inserted to facilitate the outflow of the lubricating oil.

[0032] In an optional embodiment, a block 225 is provided in the oil outlet, and the block 225 protrudes from the side wall of the connecting column 22; the block 225 is slidably connected to the oil outlet; the side of the block 225 facing the movable sleeve 23 is an inclined surface; the block 225 closes the oil outlet when the block 225 protrudes from the side wall of the connecting column 22, and opens the oil outlet when the block 225 moves into the oil outlet. The size of the oil outlet and the size of the block 225 that can achieve this function can be adopted. For example, the cross-section of the oil outlet is trapezoidal, and the closer to the axis of the connecting column 22, the wider the trapezoid is; the cross-section of the block 225 is trapezoidal, and the closer to the axis of the connecting column 22, the wider the trapezoid is. When the block 225 extends out of the oil outlet, the side wall of the block 225 contacts the side wall of the oil outlet to close the oil outlet; when the block 225 is pressed and moves into the oil outlet, the side wall of the block 225 separates from the side wall of the oil outlet to open the oil outlet; a spring may be provided between the block 225 and the inner wall of the oil outlet, or a spring may be connected between the block 225 and the flow channel 223, so that the block 225 blocks the oil outlet when not pressed; the inclined surface of the block 225 contacts the inclined surface of the movable sleeve 23, and the inclined surface of the movable sleeve 23 supports the block 225, so as to prevent the block 225 from being pressed into the oil outlet when pressed, thereby preventing the oil outlet from opening.

[0033] like Figure 4 and Figure 5 As shown, in an optional embodiment, the first connecting part 1 includes: a first sleeve 11 and a second sleeve 12; one end of the first sleeve 11 is connected to the connecting frame 3, and the other end of the first sleeve 11 is open; the second sleeve 12 is inserted into the first sleeve 11, and both ends of the second sleeve 12 are open; the end of the second sleeve 12 close to the open end of the first sleeve 11 is located in the first sleeve 11; a second ring body 13 is provided between the first sleeve 11 and the second sleeve 12; the second ring body 13 is sleeved on the second sleeve 12; one end face of the second ring body 13 is flush with the open face of the first sleeve 11; when the connecting column 22 is inserted into the second sleeve 12, the second ring body 13 will contact the movable sleeve 23, and the movable sleeve 23 is blocked by the second ring body 13 so that the movable sleeve 23 moves into the fixed sleeve 21, so that the connecting column 22 rotates.

[0034] In an optional embodiment, a chamfer is provided on the inner wall of the second sleeve 12, and the chamfer is close to the open side of the first sleeve 11; the second sleeve 12 is adapted to the connecting column 22; a notch 14 is provided on the outer wall of the first sleeve 11; the chamfer of the second sleeve 12 can guide the end of the connecting column 22, so that the connecting column 22 can be aligned with the second sleeve 12, so that the connecting column 22 can be smoothly inserted into the second sleeve 12; the notch 14 is aligned with the tail end of the second sleeve 12, and the block 225 is aligned with the notch 14 when it is exposed from the second sleeve 12. After the block 225 is exposed from the second sleeve 12, the inner wall of the second sleeve 12 no longer hinders the block 225, and the block 225 is extended out of the oil outlet to block the oil outlet through the spring. At this time, the block 225 can contact the end face of the second sleeve 12 to prevent the connecting column 22 from being pulled out of the second sleeve 12.

[0035] When the second connection part 2 is not inserted into the first connection part 1, the first spring 231 is in a compressed state, the inclined surface of the movable sleeve 23 contacts the inclined surface of the block 225, and the inclined surface of the movable sleeve 23 supports the block 225. When the block 225 is pressed, the block 225 cannot move into the oil outlet due to the obstruction of the inclined surface of the movable sleeve 23, ensuring that the oil outlet is always kept in a closed state to prevent the lubricating oil from flowing out. In the process of inserting the second connection part 2 into the first connection part 1, the guide angle of the second sleeve 12 contacts the connecting column 2. 2, plays a guiding role for the connecting column 22, so that the connecting column 22 can be aligned with the second sleeve 12, and the second ring body 13 will first contact the movable sleeve 23 before the chamfer contacts the block 225. As the connecting column 22 is inserted into the second sleeve 12, the second ring body 13 will prevent the movable sleeve 23 from moving along with the connecting column 22, and the movable sleeve 23 will move into the fixed sleeve 21. At this time, the inclined surface of the movable sleeve 23 is separated from the inclined surface of the block 225. After the block 225 contacts the chamfer, it will be pressed by the chamfer so that the block 225 moves into the oil outlet. The oil outlet is opened, and the movement of the movable sleeve 23 causes the connecting column 22 to rotate, so that the connecting column 22 rotates during the insertion of the second sleeve 12 to facilitate the insertion of the connecting column 22, and after the lubricating oil flows out of the oil outlet, the rotation of the connecting column 22 will cause the lubricating oil to be smeared on the inner wall of the second sleeve 12, and the insertion of the connecting column 22 can also be facilitated by the lubricating oil. As the connecting column 22 is inserted, the block 225 will move out of the second sleeve 12, and at this time, the inner wall of the second sleeve 12 will not block the block 225. The reset of the spring causes the block 225 to extend out of the oil outlet again, blocking the oil outlet. At this time, the block 225 is aligned with the end face of the second sleeve 12. When the connecting column 22 is pulled out, the block 225 contacts the end face of the second sleeve 12 to prevent the connecting column 22 from being pulled out. A groove may be provided on the outer wall of the connecting column 22, which corresponds to the oil outlet, so that the block 225 can move into the oil outlet until it is flush with the outer wall of the connecting column 22, preventing the block 225 from protruding out of the connecting column 22 and causing the connecting column 22 to be unable to be inserted into the second sleeve 12.

[0036] At least one other disclosed embodiment also provides a device, including: the above-mentioned joint positioning mechanism, which is arranged on the device body; the connecting frame 3 in the joint positioning mechanism is connected to the device body, and the connecting frame 3 is provided with a female head corresponding to the first connecting part 1, and the connecting plate is provided with a male head corresponding to the second connecting part 2; when the first connecting part 1 is connected to the second connecting part 2, the male head and the female head are aligned and connected.

[0037] In an optional embodiment, at least two first connection parts 1 are provided on the connection frame 3; the female head corresponds to the first connection part 1; after the first connection part 1 is connected to the second connection part 2, the male head is connected to the female head; a spring can be provided on the female head, so that when the male head contacts the female head, the spring plays a buffering role to avoid the male head hitting the female head and causing damage to both. When the block 225 extends out of the second sleeve 12, the male head and the female head are connected in place. At this time, the elastic force of the spring will cause the connecting column 22 to have a tendency to be pulled out of the second sleeve 12, so that The block 225 will contact the end surface of the second sleeve 12 to prevent the connecting column 22 from being pulled out of the second sleeve 12, thereby maintaining a stable connection between the male head and the female head; at least two first connecting parts 1 and corresponding second connecting parts 2 are provided, so that when the two first connecting parts 1 and the corresponding second connecting parts 2 are aligned, the male head and the female head are also aligned, ensuring the alignment and connection of the male head and the female head and the stability of the connection. If there is only one first connecting part 1, it cannot be guaranteed that the male head and the female head are also in an aligned state when the first connecting part 1 and the corresponding second connecting part 2 are aligned and connected.

[0038] At least one other disclosed embodiment further provides a connection method using the above-mentioned connector positioning mechanism, including: when the first connection part 1 is connected to the second connection part 2, the male connector and the female connector are aligned and connected.

[0039] In summary, the joint positioning mechanism includes: a connecting frame 3, and a first connecting part 1 arranged on the connecting frame 3; the first connecting part 1 corresponds to an adapted second connecting part 2, the second connecting part 2 is arranged on the connecting plate, and the first connecting part 1 is suitable for connecting the second connecting part 2; the second connecting part 2 includes: a fixed sleeve 21 and a connecting column 22; one end of the fixed sleeve 21 is a connecting end, which is fixed on the connecting plate, and the other end of the fixed sleeve 21 is open; the connecting column 22 is inserted into the fixed sleeve 21, and the connecting column 22 is rotatably connected to the fixed sleeve 21; one end of the connecting column 22 extends from the open end of the fixed sleeve 21; the connecting column 22 is suitable for being inserted into the second sleeve 12 of the first connecting part 1, and the connecting column 22 rotates during the insertion process of the connecting column 22; the alignment and connection of the first connecting part 1 and the second connecting part 2 are realized, so that the male head and the female head corresponding to the equipment can be aligned and stably connected, and the rotation during the connection process of the first connecting part 1 and the second connecting part 2 makes the two more smoothly and conveniently connected.
