Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of standard connectors, in particular to a multi-head connector. Background Technique
[0002] At present, there are various alloy standard parts on the market, most of which are used to connect parts or components. The traditional multi-head connector includes a connecting plate and wing plates arranged on both sides of the connecting plate. The wing plates are fixed on the external tooling by bolts, and the parts are respectively connected to the connecting plate and the tooling by additional bolts. When using the above-mentioned connector, if the bolts on one-sided wing plate accidentally come out of the wing plate or are affected by external stress and come out of the wing plate, there is no longer a bolt connecting the one-sided wing plate to the tooling, resulting in the separation of the one-sided wing plate from the tooling and causing the connecting plate to swing along the other wing plate, causing the parts or components to move accordingly, thus affecting the operation of the tooling or equipment; when using the above-mentioned connector, if the additional bolts accidentally come out of the connecting plate or are affected by external stress and come out of the connecting plate, it will cause the separation of the parts from the connecting plate, and then cause the parts to fall. Content of the Utility Model
[0003] Aiming at the deficiencies of the prior art, the utility model provides a multi-head connector to solve the problem of low fixing strength of the traditional multi-head connector.
[0004] To achieve the above object, the utility model provides a multi-head connector, including a main board. Wing plates are arranged on both sides of the main board. Vertical plates are connected between the main board and the two wing plates. The main board is arranged parallel to the wing plates and the vertical plates are arranged perpendicular to the main board. Mounting holes penetrate through the main board and the two wing plates. A connecting bolt for threadedly cooperating with a pre-embedded hole on an external tooling is threadedly connected to the mounting hole on the main board. A first thread groove is circumferentially formed on the outer peripheral wall of the connecting bolt. An auxiliary bolt for cooperating with an external tooling is threadedly connected to the mounting hole on the wing plate. A limiting cavity is formed between the inner wall of the main board and the inner walls of the two vertical plates. A first limiting member for cooperating with the connecting bolt to prevent the wing plate from rotating clockwise and a second limiting member for cooperating with the connecting bolt to prevent the wing plate from rotating counterclockwise are arranged in the limiting cavity.
[0005] The advantages of adopting the above technical solution are as follows: The operator aligns the main board with the outer wall of the external tooling, so that the mounting holes on the main board are aligned with the preset holes on the external tooling. Then, the connecting bolts are screwed into the main board from the tooling, and the connecting bolts are threadedly connected with the preset holes, the mounting holes and the external parts in sequence, so as to realize the fixed positioning of the parts on the main board. Then, the operator screws in the auxiliary bolts to realize the positioning of the wing plate on the external tooling. In the above technology, through the setting of the first limiting member, it is used to cooperate with the connecting bolt after the connecting bolt is screwed in to prevent the wing plate from rotating clockwise, and the setting of the second limiting member is used to cooperate with the connecting bolt after the connecting bolt is screwed in to prevent the wing plate from rotating counterclockwise, so as to realize the fixation of the main board on the external tooling. At the same time, when the auxiliary bolt on the single-sided wing plate is separated from the wing plate, the single-sided wing plate will not be separated from the tooling, thus improving the stability and connection strength between the parts and the tooling.
[0006] The present utility model is further provided as follows: The first limiting member includes a limiting plate arranged in the limiting cavity. A through hole for threaded cooperation with the connecting bolt is provided on the limiting plate. Limiting grooves are provided on the inner walls of the two vertical plates. The two limiting grooves are arranged oppositely, and the radial cross-section of the limiting groove is arc-shaped. The radial cross-sections of the outer peripheral walls at both ends of the limiting plate are both arc-shaped. Both ends of the limiting plate are inserted and cooperated with the two limiting grooves respectively, and the outer peripheral walls at both ends of the limiting plate are in contact and cooperation with the inner peripheral walls of their respective corresponding limiting grooves.
[0007] The advantages of adopting the above technical solution are as follows: When the main board is aligned with the tooling, the operator places the limiting plate and makes the connecting bolt in threaded cooperation with the through hole, and screws in the limiting plate so that the limiting plate is attached to the outer wall of the external tooling and both ends of the limiting plate are respectively located in the two limiting grooves, that is, both ends of the limiting plate are inserted and cooperated with the two limiting grooves respectively, and the outer peripheral walls at both ends of the limiting plate are in contact and cooperation with the inner peripheral walls of their respective corresponding limiting grooves. When the auxiliary bolt on the single-sided wing plate is separated from the wing plate, due to the arc-shaped radial cross-section of the limiting plate and the contact and cooperation between the limiting plate and the limiting groove, it is difficult for the wing plate to swing or rotate, so as to keep the single-sided wing plate in its original state all the time, thus realizing the positioning of the wing plate. Through the setting of the above technology, the stability and connection strength are improved, and the phenomenon that the parts shake or become loose due to the shaking of the single-sided wing plate is avoided.
[0008] The present utility model is further provided as follows: A limiting collar is movably arranged in the limiting cavity. A through hole for threaded cooperation with the connecting bolt is penetrated on the limiting collar. The bottom wall of the limiting collar is in contact and cooperation with the top wall of the limiting plate.
[0009] The advantages of adopting the above technical solution are as follows: After the limiting plate is installed, the limiting collar can be sleeved on the connecting bolt, and the limiting collar is screwed in so that the bottom wall of the limiting collar is in contact and cooperation with the top wall of the limiting plate, so as to realize the fixation of the limiting plate, and further improve the stability of the limiting plate and the connection strength with the wing plate.
[0010] The present utility model is further provided with: mating grooves are formed in the inner peripheral walls of both of the vertical plates, both sides of each mating groove are smoothly connected to the side walls of the corresponding vertical plate in an arc shape, the radial cross-section of each mating groove is arranged in an arc shape, second threaded grooves are formed in the inner peripheral wall of each mating groove, third threaded grooves are circumferentially formed in the outer peripheral wall of the limiting collar, and the third threaded grooves are respectively in threaded cooperation with the two second threaded grooves.
[0011] The advantages of adopting the above technical solution are as follows: through the connection and cooperation of the second threaded groove and the third threaded groove, the connection between the limiting collar and the two vertical plates is realized, thereby improving the stability of the limiting collar in the limiting cavity and the connection strength with the vertical plates, so as to improve the limiting strength of the limiting plate and the stability of the limiting plate.
[0012] The present utility model is further provided with: the thread spiral direction of the third threaded groove is opposite to the spiral direction of the first threaded groove, and the limiting collar is the second limiting member.
[0013] The advantages of adopting the above technical solution are as follows: in the above technology, the thread spiral direction of the third threaded groove is opposite to the spiral direction of the first threaded groove, so as to realize the anti-reverse function, that is, after the connecting bolt passes through the preset hole, first sleeved the limiting collar at the end of the connecting bolt, then align the main board with the external tooling, and then through the threaded cooperation of the second threaded groove and the third threaded groove, rotate the main board so that the two vertical plates rotate along the axis of the limiting collar, thereby realizing the rotation of the main board, and then by rotating the limiting collar and the main board at the same time to realize the movement of the limiting collar and the abutment against the limiting plate, and at the same time realize the alignment of the main board and the wing plate with the outer wall of the external tooling, so as to facilitate installation. By setting the thread spiral direction of the third threaded groove to be opposite to the spiral direction of the first threaded groove, the rotation direction of the limiting collar when it is screwed out is opposite to the screwing-out direction of the connecting bolt, so as to improve the stability of the connecting bolt in the limiting cavity, avoid the connecting bolt from detaching from the main board and the external tooling, and thus improve the stability and connection strength of the parts on the external tooling.
