Description

Technical Field

[0001] The present invention relates to the technical field of folding brackets, and in particular to a portable folding bracket device and a detection device. Background Art

[0002] With the development of modern science and technology, a portable linear motion bracket has emerged. Its working principle is that the portable linear motion bracket is fixed in the working area. After the operator manually unfolds it through a rotating shaft, the linear screw motion module is used to realize the stable movement of the object carried at the end. The portable linear motion bracket has the characteristics of quick folding and easy carrying, and can quickly carry out operations under more remote and complex working conditions. Therefore, more and more devices and technologies need to be equipped with portable linear motion brackets.

[0003] In the field of safety detection, after the bracket is quickly unfolded in the detection area, the operator installs the detection device at the end of the linear screw motion module, and the linear screw motion module drives the detection device to move to realize the scanning detection of the object. At present, the bracket has the problems of too slow unfolding and storage speed, resulting in slow detection efficiency, and short stroke of the bracket, resulting in insufficient detection space. The reason is that after the stroke of the bracket becomes longer, the bracket becomes loose due to the clearance error of the rotating joint at the bottom, resulting in a decrease in stability. If the stability of the bracket is insufficient, the detection accuracy will be greatly reduced. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the problem that there is a clearance error at the rotating joint of the bracket in the prior art. When the stroke of the bracket becomes longer, the bottom rotating joint is easily loosened due to the clearance error, resulting in a decrease in the stability of the bracket. Furthermore, a portable folding bracket device and a detection device are provided, which greatly reduce the accumulated clearance error at the rotating joint of the bracket, thereby reducing the inertia during the movement of the bracket and improving the overall stability of the bracket.

[0005] To solve the above technical problem, the present invention provides a portable folding bracket device, including,

[0006] A first connecting seat, which is provided with a first fitting surface and a rotating shaft perpendicular to the first fitting surface. The first fitting surface is provided with an eccentric positioning pin, the circumferential surface of the rotating shaft is provided with a first pin hole, and the inner wall of the first pin hole is provided with a first inclined surface. The first inclined surface gradually approaches the center of the first pin hole along the length direction of the first pin hole, and the first inclined surface is located on the side of the first pin hole away from the first fitting surface;

The limiting groove is in a shape-matching fit with the eccentric positioning pin. The plug pin is movably connected to the first connecting piece. The plug pin is in a shape-matching fit with the first pin hole. The elastic element presses the plug pin along the radial direction of the rotating shaft, so that the plug pin abuts against the circumferential side surface of the rotating shaft. Wherein, when an external force drives the first connecting piece to rotate, the end of the plug pin abutting against the circumferential side surface slides into the first pin hole from the circumferential side surface. The plug pin slides along the first inclined surface, and the plug pin and the first connecting piece move along the direction close to the first fitting surface. The eccentric positioning pin is inserted into the limiting groove along the axial direction of the rotating shaft, and the first fitting surface is attached to the second fitting surface.

[0008] In an embodiment of the present invention, it further includes a limiting seat. The limiting seat includes two arm bodies arranged opposite to each other and a connecting part connecting the two arm bodies. The two arm bodies are fixedly connected to the limiting seat. The two arm bodies respectively abut against both sides of the plug pin. The end of the plug pin away from the rotating shaft is arranged opposite to the connecting part. One end of the elastic element is connected to the connecting part, and the other end of the elastic element is connected to the end of the plug pin away from the rotating shaft.

[0009] In an embodiment of the present invention, the two arm bodies respectively abut against both sides of the plug pin along the axial direction of the rotating shaft.

[0011] In an embodiment of the present invention, the first connecting piece is provided with a second pin hole penetrating through the assembly hole. The plug pin is movably inserted into the second pin hole, and the side pushing surface abuts against the inner wall of the second pin hole.

[0012] In an embodiment of the present invention, the plug pin is provided with a limiting head. The limiting head is located at the end of the plug pin away from the rotating shaft, and the size of the limiting head is larger than the size of the second pin hole.

[0013] In an embodiment of the present invention, the eccentric positioning pin is semi-embedded in the first fitting surface, and the axial direction of the eccentric positioning pin is parallel to the first fitting surface. The eccentric positioning pin is rotatably connected to the first fitting surface.

The first connecting seat is arranged at the output end of the X-axis linear module; the first Z-axis linear module is arranged on the first connecting member; the second Z-axis linear module is arranged at the output end of the first Z-axis linear module.

[0015] In an embodiment of the present invention, it further includes a base, and the X-axis linear module is arranged on the base.

Wherein, the second connecting seat is provided with a second limit pin, and the second connecting member is provided with a second locking groove.

The arc-shaped chute gradually rises along the direction where the limit hole is provided, and the spring pin is inserted into the arc-shaped chute and slides along the arc-shaped chute.

[0018] In an embodiment of the present invention, both the first fitting surface and the second fitting surface are perpendicular to the horizontal plane.

[0021] The above technical solution of the present invention has the following advantages compared with the prior art:

[0022] In the portable folding bracket device described in the present invention, an elastic element is used to press the latch along the direction of the rotating shaft.

[0035] The present invention will be further described below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present invention and be able to implement it, but the embodiments cited are not intended to limit the present invention. Embodiment

[0036] Referring to Figure 1 , Figure 3 , Figure 4 , Figure 8 and Figure 9 shown, in an embodiment of the present invention, a portable folding bracket device is disclosed, including,

[0037] A first connection seat 1, which is provided with a first fitting surface 3 and a rotation shaft 4 perpendicular to the first fitting surface 3. More specifically, the rotation shaft 4 is located on the first fitting surface 3. The first fitting surface 3 is provided with an eccentric positioning pin 2. The circumferential side surface of the rotation shaft 4 is provided with a first pin hole 5. The cross section of the first pin hole 5 is rectangular. The inner wall of the first pin hole 5 is provided with a first inclined surface 36. The first inclined surface 36 extends along the length direction of the first pin hole 5. The first inclined surface 36 gradually approaches the center of the first pin hole 5 along the length direction of the first pin hole 5, and the first inclined surface 36 is located on the side of the first pin hole 5 away from the first fitting surface 3;

[0038] The first connecting member 6 is provided with an assembly hole 7 through which the rotating shaft 4 passes. Therefore, the first connecting member 6 is rotatably connected to the rotating shaft 4, and the first connecting member 6 is locked to the rotating shaft 4 by a screw 33. The first connecting member 6 is further provided with a plug pin 8, an elastic element 35, and a second fitting surface 9. The elastic element 35 is preferably a spring. The second fitting surface 9 is parallel to and faces the first fitting surface 3. The second fitting surface 9 is provided with a limiting groove 10, and the number of the limiting grooves 10 matches the number of the eccentric positioning pins 2. When the first connecting member 6 rotates to the limiting position, the limiting grooves 10 face the eccentric positioning pins 2 respectively, and the limiting grooves 10 are in profile matching with the eccentric positioning pins 2; the plug pin 8 is movably connected to the first connecting member 6 and abuts against the circumferential surface, and the elastic element 35 always presses the plug pin 8 along the radial direction of the rotating shaft 4, so that the end of the plug pin 8 close to the rotating shaft 4 always abuts against the circumferential surface of the rotating shaft 4, so that the plug pin 8 can slide over the circumferential surface and automatically insert into the first pin hole 5 to fix the first connecting member 6 and the second connecting seat 22 into one body;

[0039] Specifically, when the bracket is unfolded, an external force drives the first connecting member 6 to rotate from the horizontal state to the vertical state. When the first connecting member 6 rotates to the limiting position, the plug pin 8 just slides to the first pin hole 5 and inserts into the first pin hole 5, and the first connecting member 6 and the first connecting seat 1 achieve the first locking. At this time, the eccentric positioning pin 2 faces the limiting groove 10 along the axial direction of the rotating shaft 4. As the plug pin 8 continuously inserts into the first pin hole 5, the plug pin 8 slides on the first inclined surface 36, and the acting force of the first inclined surface 36 on the plug pin 8 pushes the plug pin 8 and the first connecting member 6 backward, so that the plug pin 8 and the first connecting member 6 slide on the rotating shaft 4 along the direction close to the first fitting surface 3 until the eccentric positioning pin 2 inserts into the limiting groove 10, and the first fitting surface 3 and the second fitting surface 9 are completely fitted, and the first connecting member 6 and the first connecting seat 1 achieve the second locking. At this time, the gap between the first connecting member 6 and the first connecting seat 1 is greatly eliminated, the gap error at the moving joint of the bracket is reduced, the shaking of the first connecting member 6 is reduced, and the overall stability and unfolding efficiency of the bracket are improved; the limiting position refers to the position when the first connecting member 6 is in the vertical state.

[0040] Furthermore, both the first fitting surface 3 and the second fitting surface 9 are perpendicular to the horizontal plane.

[0041] Referring to Figure 3 and Figure 4 As shown, furthermore, in this embodiment, both the eccentric positioning pin 2 and the limiting groove 10 are provided with four. The four eccentric positioning pins 2 are evenly distributed around the rotating shaft 4. Among them, two eccentric positioning pins 2 are distributed on both sides of the rotating shaft 4 in the vertical direction, and the other two eccentric positioning pins 2 are distributed on both sides of the rotating shaft 4 in the horizontal direction;

[0042] Referring to Figure 1 and 10 as shown, in order to limit the latch 8 and improve the stability of the latch 8, a limit seat 16 is further included. The limit seat 16 includes two arm bodies 37 arranged opposite to each other and a connecting portion 17 fixedly connecting the two arm bodies 37. The two arm bodies 37 are fixedly connected to the limit seat 16. The two arm bodies 37 respectively abut against both sides of the latch 8 to play a role in limiting, ensuring that the latch 8 can slide smoothly. One end of the latch 8 far from the rotating shaft 4 is arranged opposite to the connecting portion 17, and the connecting portion 17 is used to further limit the latch 8 to prevent the latch 8 from detaching from the first connecting member 6. One end of the elastic element 35 is connected to the connecting portion 17, and the other end of the elastic element 35 is connected to the end of the latch 8 far from the rotating shaft 4.

[0043] Further, the two arm bodies 37 respectively abut against both sides of the latch 8 along the axial direction of the rotating shaft 4, aiming to stably transmit the acting force of the first inclined surface 36 to the first connecting member 6.

[0044] Referring to Figure 9 as shown, further, side pushing surfaces 13 and second inclined surfaces 11 are respectively arranged on both sides of the latch 8 along the axial direction of the rotating shaft 4. The side pushing surfaces 13 abut against the first connecting member 6, and the side pushing surfaces 13 can immediately transmit the acting force of the latch 8 to the first connecting member 6. The second inclined surfaces 11 are located on the side of the latch 8 far from the first fitting surface 3, and the second inclined surfaces 11 are parallel to the first inclined surfaces 36. The second inclined surfaces 11 play a guiding role to facilitate the end of the latch 8 close to the rotating shaft 4 to be smoothly inserted into the first pin hole 5. After the latch 8 is inserted into the first pin hole 5, the second inclined surfaces 11 are tightly attached to the first inclined surfaces 36 and slide along the first inclined surfaces 36, so that the latch 8 is tightly inserted into the first pin hole 5, ensuring that the gap between the first fitting surface 3 and the second fitting surface 9 is minimized.

[0045] Further, the side pushing surfaces 13 are arranged as planes, and the planes can completely fit the first connecting member 6 to improve the stability of the latch.

[0046] Referring to Figure 5 as shown, in order to make the structure of the bracket more compact, the first connecting member 6 is provided with a second pin hole 32 penetrating through the assembly hole 7. The latch 8 is slidably inserted into the second pin hole 32, and the side pushing surfaces 13 abut against the first connecting member 6 along the direction of the second fitting surface 9.

[0047] Referring to Figure 5As shown, in order to prevent the bolt 8 from being fully inserted into the second pin hole 32, a limit head 12 is provided on the bolt 8. The limit head 12 is located at one end of the bolt 8 away from the rotation axis 4, and the size of the limit head 12 is larger than that of the second pin hole 32. When the bolt 8 is fully inserted into the second pin hole 32, the limit head 12 abuts against the first connecting member 6.

[0048] Referring to Figure 1 As shown, the eccentric positioning pin 2 is semi-embedded in the first fitting surface 3, and the axial direction of the eccentric positioning pin 2 is parallel to the first fitting surface 3; the eccentric positioning pin 2 is rotatably connected to the first fitting surface 3, and the rotating eccentric positioning pin 2 can reduce the friction between the first fitting surface 3 and the second fitting surface 9, improving the efficiency of the bracket deployment and storage.

[0049] Referring to Figure 1 As shown, it further includes an X-axis linear module 18 and a first Z-axis linear module 19. The first connecting seat 1 is arranged at the output end of the X-axis linear module 18, and the first Z-axis linear module 19 is arranged on the first connecting member 6. The X-axis linear module 18 can drive the first Z-axis linear module 19 to move in the horizontal direction, and the first Z-axis linear module 19 can drive the object to be carried 21 in the vertical direction. The object to be carried 21 includes a scanning detection device, etc. Therefore, the scanning detection device can lift and translate to scan and detect objects of different heights and widths, greatly expanding the working space of the scanning detection device.

[0050] Referring to Figure 2 As shown, in order to further expand the height of the bracket, it further includes a second connecting member 23 and a second connecting seat 22 that are rotatably connected. The second connecting seat 22 is connected to the output end of the first Z-axis linear module 19, and the second connecting member 23 is used to further install a Z-axis linear module or the object to be carried 21. Among them, in order to ensure that the Z-axis linear module on the second connecting member 23 can be accurately rotated to the vertical state and improve the efficiency of the bracket deployment, the second connecting seat 22 is provided with a second limit pin 25, and the second connecting member 23 is provided with a second locking groove 24. When the second connecting member 23 rotates to the limit position, the second limit pin 25 just abuts against the second locking groove 24, and the second limit pin 25 is surrounded by the second locking groove 24 to prevent the second connecting member 23 from continuing to rotate. The limit position refers to the position when the Z-axis linear module is parallel to the first Z-axis linear module 19.

[0051] Referring to Figure 1As shown, further, it further includes a second Z-axis linear module 20. The second Z-axis linear module 20 is arranged on the second connecting member 23. The output end of the second Z-axis linear module 20 is connected with a carried object 21. The second Z-axis linear module 20 can further lift the height of the carried object 21 on the basis of the basic height of the first Z-axis linear module 19.

[0052] Referring to Figure 7 As shown, in order to ensure that the first connecting member 6 can be accurately rotated to the vertical state each time, the first connecting seat 1 is provided with a first limit pin 14, and the first connecting member 6 is provided with a first locking groove 15. When the first connecting member 6 rotates to the limit position, the first limit pin 14 just abuts against the first locking groove 15, and the first limit pin 14 is surrounded in the first locking groove 15 to prevent the first connecting member 6 from continuing to rotate.

[0053] Referring to Figure 1 As shown, in order to fix the bracket firmly in the working area, it further includes a base 29, and the X-axis linear module 18 is arranged on the base 29.

[0054] Referring to Figure 1 As shown, further, the base 29 is provided with a mounting seat 31 and a rangefinder 30 arranged on the mounting seat 31. The mounting seat 31 can adjust the height of the rangefinder 30. The X-axis linear module 18 is arranged on the base 29. The rangefinder 30 is preferably an infrared laser rangefinder. Usually, the scanning detection device includes a transmitting unit and a receiving unit. The transmitting unit and the receiving unit are respectively installed on two brackets. Therefore, the rangefinder 30 is used to detect the distance and levelness between its own bracket and another bracket, so that the operator can technically adjust the position of the base 29.

[0055] Referring to Figure 2 and Figure 6As shown, in order for the second connecting member 23 and the second connecting seat 22 to be automatically locked into a fixed integral body and improve the stability of the bracket rotating joint, the second connecting member 23 is provided with a spring pin 26, the second connecting seat 22 is provided with an arc-shaped chute 28 and a limiting hole 27 located at one end of the arc-shaped chute 28. The spring pin 26 is inserted into the arc-shaped chute 28 and can slide along the arc-shaped chute 28 and finally insert into the limiting hole 27, so that the second connecting member 23 and the second connecting seat 22 are locked. Specifically, the arc-shaped chute 28 is an arc-shaped groove, which can guide the spring pin 26; the bottom of the arc-shaped chute 28 gradually rises along the direction of the limiting hole 27, which can compress the spring pin 26 to ensure that the spring pin 26 can bounce into the limiting hole 27. When the spring pin 26 slides along the direction of the limiting hole 27, the spring pin 26 is gradually compressed by the bottom of the arc-shaped chute 28 from the natural state and slides into the limiting hole 27, and the spring pin 26 bounces into the limiting hole 27; when unlocking the second connecting member 23 and the second connecting seat 22, just pull out the spring pin 26.

[0056] Referring to Figure 2 As shown, it further includes a metal level 34 arranged on the X-axis linear module 18, and the metal level 34 is used to measure the verticality of the bracket. Embodiment

[0057] There is also provided a detection device, which includes the portable folding bracket device described above and a scanning detection device. The scanning detection device is used to perform scanning detection on the object to be detected. The scanning detection device is arranged at the output end of the second Z-axis linear module. After the portable folding bracket device is fully opened, the scanning detection device can be lifted and translated by the linear module to increase the scanning detection area of the scanning detection device.

[0058] The working principle of the detection device described in the present invention is:

[0059] When unfolded, after the bracket is fixed in the working area, the operator holds and lifts the second Z-axis linear module 20. Then, the second Z-axis linear module 20 and the first Z-axis linear module 19 start to automatically flip from the horizontal state to the vertical state. When the second Z-axis linear module 20 flips to be parallel to the first Z-axis linear module 19, the second locking groove 24 just rotates to the second limit pin 25 and is blocked to form a limit. At the same time, the spring pin 26 slides in the arc chute 28 and pops into the limit hole 27. Finally, the first Z-axis linear module 19 and the second Z-axis linear module 20 are fixed together. When the first Z-axis linear module 19 flips to the vertical state, the first locking groove 15 just rotates to the first limit pin 14 and is blocked to form a limit. At the same time, the plug pin 8 automatically inserts into the second pin hole 32. The first inclined surface 36 pushes the first connecting piece 6 close to the first connecting seat 1. After the eccentric positioning pin 2 inserts into the limit groove 10, the first fitting surface 3 and the second fitting surface 9 are completely fitted. Finally, the X-axis linear module 18 and the first Z-axis linear module 19 are fixed together. After the operator adjusts the levelness of the bracket, the scanning detection device is installed at the output end of the second Z-axis linear module 20. The X-axis linear module 18, the first Z-axis linear module 19, and the second Z-axis linear module 20 drive the scanning detection device to move up and down and horizontally, and the scanning detection device starts to perform detection. When storing, the operator first disassembles the scanning detection device, then manually retracts the spring pin 26 to release the locking of the first Z-axis linear module 19 and the second Z-axis linear module 20. Then, retract the plug pin 8 to release the locking of the first Z-axis linear module 19 and the X-axis linear module 18, and then flip the second Z-axis linear module 20 and the first Z-axis linear module 19 to the horizontal state to complete the storage.

[0060] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
