Description

Technical Field

[0001] The present disclosure relates to the technical field of dragging mechanisms, and in particular, to an adaptive mechanical dragging and docking mechanism. Background Art

[0002] Currently, most of the existing dragging mechanisms are motor-driven or magnetic dragging. Among them, the motor-driven dragging mechanism drags an object with a certain power. The heat generated by the rotation of the motor is likely to cause deformation of the dragging mechanism. Moreover, when the object to be dragged is heavy, it is easy to cause the rotation speed of the motor to decrease or disappear, thus causing irreparable damage to the dragging mechanism; while the magnetic dragging mechanism needs to build a circuit in advance and can only achieve dragging and docking after being powered on. Its use is limited, and both the manufacturing and maintenance costs are relatively high. Utility Model Content

[0003] To solve the above-mentioned technical problems, the present utility model provides an adaptive mechanical dragging and docking mechanism, which adopts an adaptive method and realizes dragging and docking through mechanical principles. It not only has a low cost, but also has a wide range of uses and is easy to operate.

[0004] The present disclosure provides an adaptive mechanical dragging and docking mechanism, including a pin seat, which is horizontally arranged. The pin seat has a pin hole and a stepped portion that gradually rises from the rear side of the pin hole to the rear end of the pin seat; a plug pin, which is vertically arranged, including an upper section and a lower section. The outer circumference of the lower section of the plug pin matches the pin hole, and the height of the lower section matches the height of the pin hole, so that the lower section of the plug pin can be inserted into the pin hole. Among them, a cut surface with a higher front side and a lower rear side is formed on the lower section of the plug pin; and a docking portion, in which a horizontal first pin hole, a second pin hole and a third pin hole that are vertical and coaxial are opened. The pin seat can be inserted into the docking portion through the first pin hole. The lower section of the plug pin is installed in the second pin hole, and the upper part of the upper section is installed in the third pin hole, so that the plug pin can move up and down in the docking portion through the second pin hole and the third pin hole and be inserted into the pin hole.

[0005] Further, the inclined surface of the stepped portion matches and interacts with the inclined surface of the lower section of the plug pin. When the plug pin is inserted into the pin hole and the pin seat is continuously pushed forward, the plug pin can be jacked up.

[0006] Further, a first magnet is arranged on the upper surface of the front side of the pin seat.

[0007] Further, a second magnet is arranged on the upper surface of the plug pin, and a third magnet is arranged on the top surface of the third pin hole. The second magnet and the third magnet have opposite polarities.

[0008] Further, a limiting portion is circumferentially arranged at the lower end of the upper section of the plug pin, and a spring is arranged between the limiting portion and the lower edge of the third pin hole.

[0009] Further, the material of the lower section of the plug pin is iron, cobalt, nickel or their alloys.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0023] In addition, the term "and / or" in this document is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this document generally represents an "or" relationship between the associated objects before and after.

[0024] The following refers to Figure 1 and Figure 2 to describe an adaptive mechanical dragging and docking mechanism provided by an embodiment of the present invention, which includes a pin seat 1, a plug pin 2, and a docking part 3. Among them, the pin seat 1 is horizontally arranged and has a plug pin hole 10 and a step part 11 that gradually rises from the rear side of the plug pin hole 10 to the rear end of the pin seat 1; the plug pin 2 is vertically arranged and includes an upper section and a lower section whose outer circumference matches the plug pin hole 10 and whose height matches the height of the plug pin hole 10. The lower section of the plug pin 2 can be inserted into the plug pin hole 10. Among them, a cut surface with a higher front side and a lower rear side is formed on the lower section of the plug pin 2; a horizontal first pin hole 30, a vertical second pin hole 31, and a third pin hole 32 are formed in the docking part 3. The second pin hole 31 and the third pin hole 32 are coaxial. The pin seat 1 is inserted into the docking part 3 through the first pin hole 30, and the plug pin 2 is installed in the second pin hole 31 and the third pin hole 32. Among them, the lower section of the plug pin 2 is installed in the second pin hole 31, and the upper part of the upper section is installed in the third pin hole 32, so that the plug pin 2 can move up and down vertically in the docking part 3 through the second pin hole 31 and the third pin hole 32 and be inserted into the plug pin hole 10 on the pin seat 1.

[0025] In this embodiment, when the pin seat 1 is not inserted into the docking part 3, the plug pin 2 is installed in the second pin hole 31 and the third pin hole 32. At this time, the bottom end of the lower section of the plug pin 2 abuts against the lower surface of the first pin hole 30, and a specific distance is left between the upper surface of the upper section of the plug pin 2 and the top surface of the third pin hole 32.

[0026] At this time, insert the pin seat 1 into the docking part 3 and apply a forward force to the pin seat 1. As Figure 2 shown, the docking mechanism is in the first position, that is, the initial position. Because a cut surface with a higher front side and a lower rear side is formed on the lower section of the plug pin 2, when the front end of the pin seat 1 contacts the inclined surface of the lower section of the plug pin 2, the plug pin 2 is pushed up by an upward force, and the pin seat 1 also continues to move forward. As Figure 3As shown, the docking mechanism is in the second position. When the pin seat 1 moves until the bottom end of the lower section of the bolt 2 abuts against the front side of the bolt hole 10, the bolt 2 drops downward into the bolt hole 10.

[0027] At this time, as Figure 4 shown, the docking mechanism is in the third position, i.e., the locked position, where the bolt 2 and the pin seat 1 are locked to each other, that is, the pin seat 1 and the docking part 3 are locked.

[0028] In this embodiment, the inclined surface of the stepped portion 11 matches the inclined surface of the lower section of the bolt 2. When the lower section of the bolt 2 is completely inserted into the bolt hole 10, the two inclined surfaces are on the same plane. At this time, when the pin seat 1 is pushed forward, the two inclined surfaces interact with each other. Specifically, the stepped portion 11 applies an upward force to the lower section of the bolt 2, pushing the bolt 2 upward, as Figure 5 shown, the docking mechanism is in the fourth position.

[0029] In this embodiment, a second magnet 20 is provided on the upper surface of the upper section of the bolt 2, and a third magnet 33 is provided at the corresponding position on the top surface of the top end of the third pin hole 32. The second magnet 20 and the third magnet 33 have opposite magnetic polarities. When the distance between the two magnets is reduced to a specific distance, due to the magnetic attraction force between the two magnets, the bolt 2 is attracted upward, and its upper surface abuts against the top surface of the top end of the third pin hole 32.

[0030] Among them, the upper section of the bolt 2, the docking part 3 and the pin seat 1 are all made of non-magnetic materials, and the lower section of the bolt 2 is made of magnetic material, usually iron, cobalt, nickel or their alloys.

[0031] The bolt 2 is pushed upward by the upward force applied by the stepped portion 11, and the pin seat 1 also continues to move forward accordingly. When the bottom end of the lower section of the bolt 2 abuts against the highest point of the stepped portion 11, the distance between the second magnet 20 on the upper surface of the bolt 2 and the third magnet 33 on the top surface of the top end of the third pin hole 32 is reduced to the specific distance at which the two magnets can attract each other. Under the action of the magnetic force of the second magnet 20 and the third magnet 33, the bolt 2 is attracted upward.

[0032] At this time, as Figure 6 shown, the docking mechanism is in the fifth position, i.e., the unlocked position, where the bolt 2 and the pin seat 1 are unlocked from each other, that is, the pin seat 1 and the docking part 3 are unlocked.

[0033] In this embodiment, a first magnet 12 is provided on the upper surface of the front side of the pin seat 1. When the bolt 2 is in the unlocked position, the second magnet 20 and the third magnet 33 attract each other. At this time, when the pin seat 1 is dragged backward, since there is no blocking object other than the pin seat 1 in the first pin hole 30, the pin seat 1 can move smoothly backward in the first pin hole 30 until the first magnet 12 is located below the bolt 2. Since the lower section of the bolt 2 is made of magnetic material, there is also an attraction force between the lower section of the bolt 2 and the first magnet 12.

[0034] In this embodiment, when the bolt 2 is in the unlocking position and the first magnet 12 is located below the bolt 2, the magnetic force between the lower segment of the bolt 2 and the first magnet 12 is greater than the magnetic force between the second magnet 20 and the third magnet 33, so that the bolt 2 can fall under the attraction of the first magnet 12. During this process, according to the actual situation, the distance between the bottom end of the lower segment of the bolt 2 and the first magnet 12 also needs to be considered. By reasonably setting the magnetic force magnitudes of the first magnet 12, the second magnet 20, and the third magnet 33, and the distance between the bottom end of the lower segment of the bolt 2 and the first magnet 12 when the bolt 2 is in the unlocking position, the bolt 2 can move up and down flexibly and be fixed.

[0035] In this embodiment, a specific distance is left between the first magnet 12 and the bolt hole 10, so that when the bottom end of the lower segment of the bolt 2 is located above the bolt hole 10, it is not affected by the first magnet 12.

[0036] In this embodiment, the bolt 2 falls under the attraction of the first magnet 12, and the bottom end of its lower segment abuts against the first magnet 12. At this time, continue to drag the socket 1 backward until it returns to the initial position as shown in Figure 2 shown.

[0037] In this embodiment, the force applied when pushing / dragging the socket 1 is much greater than the suction force between the lower segment of the bolt 2 and the first magnet 12, so that the movement of the socket 1 in the first pin hole 30 is not affected by the first magnet 12 and the lower segment of the bolt 2.

[0038] In this embodiment, a spring 4 is arranged on the outer periphery of the bolt 2. Specifically, a limiting portion 21 is circumferentially arranged at the lower end of the upper segment of the bolt 2, and the spring 4 is installed between the limiting portion 21 and the lower edge of the third pin hole 32, providing a buffering effect for the up and down movement of the bolt 2 in the second pin hole 31 and the third pin hole 32, preventing the bolt 2 from moving too far up or down and being accidentally attracted under the action of the magnet.

[0039] In this embodiment, the socket 1 and the docking portion 3 can be respectively installed on different devices or apparatuses. For example, the socket 1 can be installed on a robot, and the docking portion 3 can be installed on an object to be dragged, so as to realize the dragging of the object by the robot. Moreover, according to the length of the socket 1, the step portion 11, the bolt hole 10, and the position of the first magnet 12, the moving distance of pushing / dragging the socket 1 can be set in advance, further improving the docking accuracy of the docking mechanism.

[0040] According to the embodiments of the present disclosure, the following technical effects are achieved:

[0041] By providing the pin seat 1 and the pin 2 that can be inserted into the pin seat 1, the locking of the docking mechanism is simply achieved, the cost is reduced, and the scope of use is expanded; by providing the stepped portion 11 inclined surface and the lower section inclined surface of the pin 2 that cooperate with each other, the pin 2 can be easily jacked up, so as to achieve the unlocking of the docking mechanism; by providing the second magnet 20 and the third magnet 33, the unlocking of the docking mechanism is flexibly and simply achieved; by making the lower section of the pin 2 made of magnetic material and providing the first magnet 12 in the pin seat 1, the reset of the docking mechanism is flexibly and simply achieved; by providing the limiting portion 21 and the spring 4, a buffer is provided for the movement of the pin 2 in the docking mechanism, and the docking accuracy is improved; during the entire dragging process, it depends on the adaptive cooperation between the pin 2 and the pin seat 1, and the dragging docking can be achieved only through mechanical principles.
