Description

Technical Field

[0001] The utility model relates to a connector, in particular to a cross-axis bolt connector, belonging to the technical field of cross-axis bolt connection. Background Art

[0002] Connectors are also called connectors. Mechanical properties: In terms of connection function, plugging and pulling force is an important mechanical property. The plugging and pulling force is divided into insertion force and extraction force (extraction force is also called separation force). The requirements of the two are different. The relevant standards have maximum insertion force and minimum separation force regulations, which shows that from the perspective of use, the insertion force should be small (thus there are low insertion force LIF and no insertion force ZIF structures), and if the separation force is too small, it will affect the reliability of the contact. The plugging and pulling force and mechanical life of the connector are related to the contact structure (positive pressure size), the quality of the coating on the contact part (sliding friction coefficient), and the contact arrangement size accuracy (alignment degree);

[0003] When the existing cross-axis bolt connector is in use, the cross-axis bolt is fixed by friction between the cross-axis bolt and the connector surface or by fixing bolts and other parts passing through the cross-axis bolt. The cross-axis bolt is easy to fall off during use, and the cross-axis bolt is inconvenient to disassemble and assemble. When the cross-axis bolt is partially broken inside the connector, it is not convenient to remove and replace the broken part.

[0004] In order to solve the above technical problems, a cross-axis bolt connector is proposed. Utility Model Content

[0005] In view of this, the utility model provides a cross-axis bolt connector to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial choice.

[0006] The technical solution of the utility model is implemented as follows: a cross-axis bolt connector, including a main body mechanism and a locking mechanism;

[0007] The main body mechanism comprises a connecting shaft, and a cross groove is integrally formed on one side of the connecting shaft;

[0008] The locking mechanism includes a locking sleeve and steel balls. The locking sleeve is sleeved on one side of the connecting shaft. The locking sleeve is threadedly connected to the connecting shaft. Four mounting grooves are evenly distributed inside the connecting shaft. The mounting grooves are connected to the cross grooves. The steel balls are evenly distributed on one side of the interior of the mounting grooves. A locking plate is slidably installed on one side of the interior of the mounting grooves.

[0009] Further preferably, a magnetic block is symmetrically fixedly connected to one side of the interior of the installation groove.

DETAILED DESCRIPTION

[0024] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0025] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0026] like Figure 1 As shown in FIG. 4 , an embodiment of the utility model provides a cross-axis bolt connector, which is composed of a main body mechanism 10 and a locking mechanism 20.

[0027] The main body mechanism 10 includes a connecting shaft 11, a pad 14 and a limit plate 15. A cross groove 12 is integrally formed on one side of the connecting shaft 11 for inserting the cross end of the cross-axis bolt into the connecting shaft 11. A slot 13 is integrally formed on one side of the connecting shaft 11. The pad 14 is engaged with the connecting shaft 11 through the slot 13. After the cross-axis bolt is connected to the connecting shaft 11, the external connection is locked and straightened by the pad 14 to make the connection between the cross-axis bolt and the connecting shaft 11 more stable. The limit plate 15 is fixedly connected to one side of the pad 14 to limit the depth of the pad 14 penetrating into the slot 13.

[0028] The locking mechanism 20 includes a locking sleeve 21, a steel ball 23 and a locking plate 24. The locking sleeve 21 is sleeved on one side of the connecting shaft 11. The locking sleeve 21 is threadedly connected to the connecting shaft 11 so that the locking sleeve 21 can move axially relative to the connecting shaft 11 when rotating. Four mounting grooves 27 are evenly spaced inside the connecting shaft 11. The mounting grooves 27 are connected to the cross groove 12. The steel balls 23 are evenly spaced and arranged on one side of the inside of the mounting grooves 27. The locking plates 24 are evenly spaced and arranged on one side of the inside of the mounting grooves 27. When the locking sleeve 21 moves, the steel balls 23 are squeezed so that the steel balls 23 drive the locking plate 24 to move. Through the locking plate 24 and the cross groove The cross-axis bolt in 12 is locked and fixed without the need for additional connecting parts. Slide grooves 16 are symmetrically and evenly distributed on one side of the inner part of the connecting shaft 11. A slider 17 is slidably connected inside the slide groove 16. One side of the slider 17 is fixedly connected to the locking plate 24. The locking plate 24 is limited by the slide groove 16 and the slider 17 to prevent the locking plate 24 from escaping from the mounting groove 27 and to enhance the stability of the locking plate 24 during movement. An anti-skid pad 25 is fixedly connected to one side of the locking plate 24 to enhance the friction between the contact surface of the locking plate 24 and the cross-axis bolt through the anti-skid pad 25 and to prevent the locking plate 24 from causing wear on the surface of the cross-axis bolt.

[0029] In one embodiment, in order to prevent the locking plate 24 from affecting the insertion of the cross-axis bolt, a magnetic block 26 is symmetrically fixedly connected to one side of the interior of the mounting groove 27. The locking plate 24 is made of a metal material that can be adsorbed by the magnetic block 26. The magnetic block 26 adsorbs the locking plate 24 to fix the initial position of the locking plate 24, thereby preventing the locking plate 24 from blocking the cross slot 12 and causing the cross-axis bolt to be unable to be inserted.

[0030] In one embodiment, in order to facilitate the rotation of the locking sleeve 21, key slots 22 are evenly spaced on one side of the locking sleeve 21.

[0031] When the utility model is working, the backing plate 14 is mounted on the cross end of the cross shaft bolt, and the cross end of the cross shaft bolt is inserted into the cross groove 12, so that the cross shaft bolt drives the backing plate 14 to be clamped into the clamping groove 13. When the cross shaft bolt is inserted, the magnetic block 26 absorbs the locking plate 24 to prevent the locking plate 24 from blocking the cross groove 12. After the cross shaft bolt is inserted into the connecting shaft 11, the locking sleeve 21 is rotated to move the locking sleeve 21 toward the steel ball 23, so that the locking sleeve 21 squeezes the steel ball 23. At this time, the steel ball 23 drives the locking plate 24 to the cross shaft bolt. The cross shaft bolt is moved in the direction, and the anti-skid pad 25 on one side of the locking plate 24 contacts with the cross shaft bolt to lock and fix the cross shaft bolt. After locking the cross shaft bolt, the limit plate 15 is knocked to make the pad 14 completely snap into the slot 13, and the external connection is locked and straightened to complete the connection of the cross shaft bolt. When removing the cross shaft bolt, the locking sleeve 21 is rotated in the opposite direction so that the locking sleeve 21 no longer squeezes the steel ball 23, and the magnetic block 26 absorbs the locking plate 24 so that the locking plate 24 no longer locks and fixes the cross shaft bolt, and the cross bearing can be pulled out.

[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
