Description

Technical Field

[0001] This utility model relates to the field of turning connector technology, and in particular to a multi-angle adjustment structure for a support rod turning connector. Background Technology

[0002] In the modern construction and decoration industry, the support rod bend connector is a common connection device widely used in various curtain installation and curtain support tasks. However, in practical applications, the diversity of wall angles brings many challenges to the installation and adjustment of the support rod.

[0003] Traditional support rod bend connectors often only provide limited adjustment angles and cannot adapt to complex and varied wall angles. For example, when there are irregular corners on the wall, traditional connectors have difficulty achieving stable support and precise adjustment to adapt to the corner angle. Therefore, developing a support rod bend connector that can adapt to various wall angles has become an urgent problem to be solved. Utility Model Content

[0004] The purpose of this invention is to provide a multi-angle adjustable structure for a support rod turning connector. This turning connector can be adjusted according to different actual angles, ensuring stable support and precise adjustment at various angles.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a multi-angle adjustment structure for a support rod turning connector, including a left-turning component, a right-turning component, and a connecting block connecting the left-turning component and the right-turning component. The connecting block has two transition grooves, and each of the two transition grooves has a rotatable transition bolt. Each transition bolt is fixedly connected to the corresponding left-turning component and right-turning component. A driving chamber is provided between the two transition grooves. A slide rail communicating with the transition grooves is provided in the driving chamber. Locking pins are slidably provided in the slide rail. Each of the two locking pins includes two rods facing away from each other and heads facing towards each other. Each of the two transition bolts has several locking grooves arranged at intervals along its circumference. The locking grooves correspond to the slide rails. A locking mechanism for driving the two rods into or out of the locking grooves is provided in the driving chamber.

[0006] By adopting the above technical solution, the adapter bolt has several locking grooves arranged at intervals along its circumference. The locking grooves on the adapter bolt provide multiple angle adjustment locks for the left-turning and right-turning parts. By inserting the locking pin into the locking groove at the corresponding angle, the included angle between the left-turning and right-turning parts is locked, thereby ensuring stable support and precise adjustment at various angles.

[0007] The locking mechanism is further configured as follows: a cam is located in the drive chamber and disposed between two heads; a spring is sleeved on each rod; a rotating shaft extending outward is fixedly connected to the cam; a rotating block is fixedly disposed at one end of the rotating shaft extending outward; the ends of the two heads facing the cam are both abutting against the outer peripheral surface of the cam; one end of the spring is fixedly connected to the head and the other end is fixedly connected to the wall of the drive chamber.

[0008] By adopting the above technical solution, through the setting of cam, rotating shaft and rotating block, the rotating block is manually rotated, the rotating block drives the rotating shaft and cam to rotate, the rotation of the cam will control the heads of the two locking pins to move simultaneously, the rod moves along the slide under the push of the head until it enters the locking groove of the adapter bolt, and locks. The locking mechanism adopts an easy-to-operate design, and the operator can complete the locking and unlocking operations without additional tools; at the same time, through the setting of spring, the spring is compressed, the spring causes the two locking pins to move towards each other, providing a restoring force when unlocking. The spring is low in cost and has good practicality and reliability.

[0009] The cam is further configured such that its cross-section is elliptical, and each of the two heads facing the cam has an arc-shaped limiting groove, with the two ends of the longest radius of the cam matching the corresponding arc-shaped limiting groove.

[0010] By adopting the above technical solution and setting the arc-shaped limiting groove, when the two ends of the longest radius of the cam move into the corresponding arc-shaped limiting groove, the locking pin rod is in a stable state of being inserted into the locking groove, thus maintaining a stable locking state.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings.

[0018] refer to Figures 1 to 5 A multi-angle adjustable structure for a support rod turning connector includes a left-turning component 11, a right-turning component 12, and a connecting block 2 connecting the left-turning component 11 and the right-turning component 12. The connecting block 2 has two transition grooves 21, each containing a rotatable transition bolt 3. Each transition bolt 3 is fixedly connected to the corresponding left-turning component 11 and right-turning component 12. Both the left-turning component 11 and right-turning component 12 have a first through groove 32 and a hexagonal through groove 33. The transition bolt 3 passes sequentially through the hexagonal through groove 33, the transition groove 21, and the first through groove 32. A screw cap 7, threadedly connected to one end of the transition bolt 3, is located within the first through groove 32. The other end of the transition bolt 3... The ends are hexagonal and fit into hexagonal through slots, so that the two bolts 3 are fixed on the left-turning part 11 and the right-turning part 12 respectively. A drive chamber 22 is opened between the two transition slots 21. A slide 23 connecting the transition slots 21 is opened in the drive chamber 22. A locking pin 4 is slidably arranged in the slide 23. Each of the two locking pins 4 includes two rods 41 facing away from each other and heads 42 facing each other. Each of the two transition bolts 3 has several locking slots 31 arranged at intervals along its circumference. The locking slots 31 correspond to the slide 23. A locking mechanism is provided in the drive chamber 22 to drive the two rods 41 into or out of the locking slots 31.

[0019] The locking mechanism includes a cam 5 located within the drive chamber 22 and positioned between two heads 42; a spring 6 fitted onto each rod 41; a rotating shaft 51 extending outwards fixedly connected to the cam 5; and a rotating block 52 fixedly mounted on one end of the rotating shaft 51 extending outwards. The ends of the two heads 42 facing the cam 5 abut against the outer circumferential surface of the cam 5. One end of the spring 6 is fixedly connected to the head 42, and the other end is fixedly connected to the wall of the drive chamber 22. The cam 5 has an elliptical cross-section, and each of the two heads 42 has an arc-shaped limiting groove 421 on the side facing the cam 5. The two ends of the longest radius of the cam 5 are adapted to the corresponding arc-shaped limiting groove 421. When the two ends of the longest radius of the cam 5 move into the corresponding arc-shaped limiting groove 421, the rod 41 of the locking pin 4 is in a stable state of being inserted into the locking groove 31.

[0020] Overall workflow: For walls with different corner angles, first, manually rotate the left rotating part 11 or the right rotating part 12 around another rotating part. The left rotating part 11 or the right rotating part 12 will rotate around the adapter bolt 3. When the included angle between the left rotating part 11 and the right rotating part 12 is consistent with the corner of the wall, manually rotate the rotating block 52 90 degrees counterclockwise or clockwise. The rotating block 52 drives the rotating shaft 51 and the cam 5 to rotate. At this time, the two ends of the longest radius of the cam 5 push the two heads 42 at the same time, which will drive the two rods 41 to insert into the corresponding locking grooves 31 to lock the included angle between the left rotating part 11 and the right rotating part 12, thus locking the left rotating part 11. The fixed limit of the angle between the left-turning component 11 and the right-turning component 12 provides stable support. When it is necessary to change to other corners, the angle between the left-turning component 11 and the right-turning component 12 can be readjusted by manually rotating the rotating block 52 90 degrees counterclockwise or clockwise. The rotating block 52 drives the rotating shaft 51 and the cam 5 to rotate. At this time, the two ends of the longest radius of the cam 5 move away from the two heads 42 at the same time. The compressed spring 6 gets the restoring force, which makes the head 42 of the locking pin 4 move towards the two ends of the shortest radius of the cam 5, so that the rod part 41 of the locking pin 4 disengages from the locking groove 31, thereby opening up the angle between the left-turning component 11 and the right-turning component 12.

[0021] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
