Technical Field

[0001] The utility model relates to the technical field of mechanical connectors, and particularly relates to a connection component with a limit. Background Art

[0002] With the continuous development of social economy and social science and technology, interactive devices, such as displays, integrated terminals, instruments, etc., are becoming more and more miniaturized and integrated. During use, brackets are often required for cooperation to facilitate installation and fixation, angle adjustment, and easy observation and use.

[0003] In the prior art, as disclosed in the application number CN202323023560.2, a movable bracket assembly is provided. A first rotation hole is formed in the middle of the rotation installation mechanism, and a bolt is inserted through the rotation hole. The inner end of the bolt passes through the top of the connecting piece and is fixed by a nut; the rotating body is clamped below the connecting piece, and rotating arms are respectively arranged on both sides below the connecting piece. Mounting holes are correspondingly arranged in the connecting piece below, the rotating body and the rotating arms, and fixing bolts are inserted through the mounting holes to realize the relative rotation of the connecting piece and the rotating arms.

[0004] Its structure is simple and has a high adaptability. At the same time, it can also realize left - right rotation connection and up - down rotation connection. However, the applicant found in actual use and research and development that although the movable bracket can realize left - right rotation connection and up - down rotation connection, its locking force is poor, and it is easy to loosen and slip during rotation connection, resulting in poor stability. Summary of the Utility Model

[0005] I. Technical Problems to be Solved

[0006] Aiming at the deficiencies of the prior art, the utility model provides a connection component with a limit, which can have a strong locking force and stability while being able to rotate left - right and up - down after the interactive device is installed, and can ensure the stability of the rotation adjustment of the interactive device.

[0007] II. Specific Technical Solutions

[0008] A connection component with a limit includes a base, a connecting piece, and a mounting seat arranged in sequence. The first end of the connecting piece rotates up and down on one side of the base, and the second end of the connecting piece rotates left - right and is connected to one side of the mounting seat. A first limiting member is arranged on the first end. The side of the base connected to the first end sinks to form an arc - shaped supporting edge, and when the first end rotates up and down on the base, the first limiting member moves closely along the supporting edge.

[0009] Implementation principle, working principle: The connection component in this solution is mainly used for the installation of interactive devices. The base is connected to the bracket, and the interactive device is fixed on the mounting base by bolts. During specific applications, the angle of the interactive device can be adjusted by adjusting the angle of the connecting piece on the base. When the connecting piece rotates up and down, since the first limiting piece always abuts against the arc-shaped supporting edge, it can support the connecting piece and the interactive device connected thereto, preventing it from loosening and directly falling, which affects its stability. The supporting edge is formed by sinking, and both sides of it can limit the rotation range of the first limiting piece to prevent the connecting piece from rotating too much and becoming loose.

[0010] Preferably: A first mounting hole is provided at the end of the first end. A first locking knob is provided on one side of the base. One end of the first locking knob is provided with a first locking screw. The first locking screw passes through the base and the first mounting hole, and a locking nut is cooperatively provided at the end of the first locking screw. The beneficial effect of this preference is that by rotating the locking knob, it is convenient to adjust the angle of the connecting piece and also convenient for the disassembly and assembly between the connecting piece and the base.

[0011] Preferably: A second mounting hole is provided in the middle of the first end. The second mounting hole is used for the installation of the first limiting piece. The first limiting piece is one of a screw or a pin. The center of rotation of the up and down rotation of the connecting piece is the same as the center of the supporting edge. The beneficial effect of this preference is that through the setting of the pin and the screw, the disassembly and assembly are convenient, and the position and the central angle of the supporting edge of the first limiting piece can ensure the support of the supporting edge on the first limiting piece.

[0012] Preferably: A third mounting hole is provided on the side of the mounting base connected to the connecting piece. The second end of the connecting piece is matched with the third mounting hole. A second locking knob is provided on the mounting base. A second locking screw is formed on the second locking knob. The second locking screw abuts against the second end of the connecting piece through a threaded hole on the side wall of the mounting base. The beneficial effect of this preference is that the second end of the connecting piece is connected in a shaft-hole matching manner, which is convenient for the rotational setting of the connecting piece. Among them, through the cooperation of the second locking knob and the second locking screw, the second end of the connecting piece and the mounting base can be stably connected, and at the same time, the angle between the second end and the mounting base can be simply and conveniently adjusted to achieve left and right rotation.

[0013] As a preference, a receiving portion is formed by sinking on one side of the end of the connecting piece. A second limiting piece is further provided outside the mounting base. The second limiting piece extends into the receiving portion through a threaded hole on the side wall of the mounting base. The beneficial effect of this preference is that through the setting of the second limiting piece, the position and the rotation angle of the second end of the connecting piece can be restricted, avoiding the rotation angle of the connecting piece being too large and affecting the installation stability of the interactive device.

[0014] As a preference, the second limiting member is any one of a screw or a pin.

[0015] As a preference, a spring piece is further arranged on the outer side of the mounting base. The fixed end of the spring piece is fixed on the mounting base through the second limiting member. A catch ball is fixedly arranged at the movable end of the spring piece. A through hole is further arranged on the side wall of the mounting base. The catch ball passes through the through hole and abuts against the second end of the connecting member. The beneficial effect of this preference is that through the arrangement of the spring piece, the catch ball and the side wall of the connecting member can be closely attached, so as to form support and fixation of the connecting member, further improving the connection stability between the connecting member and the mounting base.

[0016] As a preference, accommodation grooves are further arranged at intervals in the circumferential direction of the second end of the connecting member. The accommodation grooves are matched with the catch balls. The beneficial effect of this preference is that through the cooperation between the accommodation grooves and the catch balls, the relative sliding between the catch balls and the second end of the connecting member can be prevented, so as to avoid affecting the connection stability between the two.

[0017] As a preference, a fixing screw is further arranged on the side wall of the mounting base. The fixing screw is used for fixedly arranging the middle part of the spring piece on the mounting base. The beneficial effect of this preference is that through the cooperation of the fixing screw and the second limiting member, the spring piece can be better attached to the outer wall of the mounting base, and the spring piece can better make the catch ball and the connecting member fit, with better stability.

[0018] The beneficial effects of the present utility model are as follows:

[0019] 1. Through the cooperation of the supporting edge and the first limiting member, the connection between the connecting member and the base can be supported, effectively avoiding the detachment and slipping of the interaction device when there is slight looseness between the connecting member and the base. At the same time, through the cooperation between the connecting member and the mounting base, the second locking screw, the spring piece and the catch ball, the detachment after the connection between the connecting member and the mounting base can be avoided, effectively ensuring its stability.

Detailed implementation mode

[0029] The following elaborates on the preferred embodiments of the present utility model in conjunction with the drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] As Figure 1 shown:

[0031] A connection component with a limit is used to install an interaction device on a bracket or a required use position, such as Figure 1 , from left to right, mainly composed of a base 1, a connecting piece 2 and a mounting seat 3; during implementation, as Figure 1 and Figure 2 shown, the first end 4 of the connecting piece 2 rotates up and down on one side of the base 1. In this embodiment, the first end 4 of the connecting piece 2 is connected to the base 1 by a pivoting method, where the base 1 is used to connect the mounting bracket of the interaction device; the second end 5 of the connecting piece 2 is rotatably connected to one side of the mounting seat 3, specifically by a shaft-hole cooperation method.

[0032] Specifically, as Figure 1 and Figure 2 shown, a first mounting hole 8 is provided at the end of the first end 4 of the connecting piece, and a first locking knob 9 is provided on the outside of the base 1; as Figure 3, one end of the first locking knob 9 is integrally formed with a first locking screw 10. The other end of the first locking screw 10 passes through the base 1 and the first mounting hole 8, and a locking nut 11 is arranged at the end of the first locking screw 10. The locking nut 11 and the first locking knob 9 are respectively arranged on both sides of the base 1. By adjusting the first locking knob 9, the tightness between the connecting member 2 and the base 1 can be adjusted.

[0033] During implementation, specifically as Figure 1 and Figure 4 , a first limiting member 6 is arranged on the first end of the connecting member 2. A second mounting hole 12 is formed in the middle of the first end. The second mounting hole 12 is a threaded hole, and the first limiting member 6 is a screw or a pin that matches the second mounting hole 12; a circular arc-shaped supporting edge 7 is formed by sinking on the side of the base 1 connected to the first end 4. When the first end 4 rotates on the base 1, the first limiting member 6 moves closely against the supporting edge 7. The supporting edge 7 will support the connecting member 2 and the interactive device connected thereto through the first limiting member 6. The center of the up-and-down rotation of the connecting member 2 is the same as the center of the supporting edge 7, ensuring that it can move closely against the supporting edge 7 and preventing it from loosening and directly falling off.

[0034] During implementation, as Figure 1 , Figure 5 and Figure 6 shown, a third mounting hole 13 is formed on the side of the mounting seat 3 connected to the connecting member 2. The second end 5 of the connecting member 2 is matched with the third mounting hole 13. The middle of the second end 5 contracts inward to facilitate the limit and anti-detachment between the second end 5 and the mounting seat 3. A second locking knob 14 is arranged on the mounting seat 3. A second locking screw 15 is formed on the second locking knob 14. The second locking screw 15 passes through the threaded hole on the side wall of the mounting seat 3 and abuts against the second end of the connecting member 2, specifically against the position where the middle of the second end 5 contracts inward.

[0035] During implementation, as Figure 6 , a receiving portion is formed by sinking on one side of the end of the connecting member 2. A second limiting member 16 is also arranged outside the mounting seat 3. Specifically, the second limiting member 16 is any one of a screw or a pin. In this embodiment, it is a long screw threadedly connected to the mounting seat 3. The second limiting member 16 extends into the receiving portion through the threaded hole on the side wall of the mounting seat 3. Through the setting of the second limiting member 16, the position and rotation angle of the second end 5 of the connecting member 2 can be restricted, preventing the rotation angle of the connecting member 2 from being too large and affecting the installation stability of the interactive device.

[0036] 3. During implementation, as Figure 6As shown, in order to make the connection between the connecting member 2 and the mounting base 3 more stable, a spring piece 17 is further provided on the outer side of the mounting base 3. In this embodiment, the fixed end of the spring piece 17 is fixed to the outer wall of the mounting base 3 by a second limiting member 16, and a detent 18 is fixedly provided at the movable end of the spring piece 17. A through hole is further provided on the side wall of the mounting base 3, and the detent 18 passes through the through hole and abuts against the second end 5 of the connecting member 2. The connecting member 2 and the mounting base 3 are stably connected together by the elastic recovery of the spring piece 17. During implementation, such as Figure 2 , in order to prevent relative sliding between the detent 18 and the second end 5 of the connecting member 2, a plurality of receiving grooves 19 are evenly spaced in the circumferential direction of the second end 5 of the connecting member 2. The cooperation between the detent 18 and the plurality of receiving grooves 19 can prevent slippage and affect the locking effect. During implementation, in order to maintain the elastic force of the spring piece 17, a fixing screw 20 is further provided on the side wall of the mounting base. The fixing screw 20 fixes the middle part of the spring piece 17 on the mounting base 3.

[0037] Through the cooperation of the supporting edge 7 and the first limiting member 6, this solution can form a support for the connection between the connecting member 2 and the base 1, effectively preventing the interactive device from falling off and slipping when there is a slight looseness between the connecting member 2 and the base 1. At the same time, through the cooperation between the connecting member 2 and the mounting base 3, the second locking screw 15, the spring piece 17 and the detent 18, it can prevent the connecting member 5 from falling off after being connected to the mounting base 6, effectively ensuring its stability. The structure of this solution is more stable, has a large locking force, can bear a large gravity, can meet the connection requirements of more specifications of interactive devices, and its structure can also achieve rotational limiting in a specific range in all directions. Its product structure is simple, can be quickly produced and assembled, and the production efficiency is greatly improved.
