Technical Field
[0001] This utility model belongs to the field of stent technology, and specifically relates to a joint component and a stent. Background Technology
[0002] In daily life, stands can be used to mount various tools, such as microphones, cameras, or lamps. Since these tools need to be adjusted according to various usage environments, rotating joints are installed on the stands so that the stands themselves can change their angle, thereby causing the tools to change their placement angle.
[0003] In the prior art, the adjustment of the joint components of the support is achieved through a damping shaft. That is, one end of the two support arms is provided with a hinged support, and the other end is provided with a hinged arm. The hinged arm extends into the hinged support and is pivotally hinged to the hinged support. The adjustment of the joint components of the support is achieved through the damping shaft that is pivotally hinged.

Utility Model Content
[0005] The main objective of this invention is to provide a joint assembly and support for a bracket. The hinge arm of the rotating head is pivotally hinged to two hinge pins of the hinge joint. The diameters of the two hinge pins gradually increase in an inclined manner from the free end to the fixed end. Compared to traditional damping shafts, this not only increases the contact area generated during damping rotation, thus increasing the magnitude of rotational damping, but also, due to the inclined design of the increased contact area, increases the vertical pressure between the surfaces of the two hinge pins and the inner wall of the hinge perforation, further increasing the magnitude of rotational damping and extending the service life of the bracket's joint assembly. This is beneficial for the widespread adoption of brackets.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A joint assembly for a support includes: a hinge joint and a rotating head. The hinge joint includes: two mutually fixed semi-hinged joints, each of the two semi-hinged joints having a support arm at one end. The rotating head has a hinge arm at one end, the hinge arm extending into the space between the two support arms. Both of the support arms extend inward to form hinge posts. The hinge arms are provided with hinge holes. The free ends of the two hinge posts extend into the hinge holes from both sides and abut against each other, so that the hinge arms are pivotally hinged to the two support arms through the two hinge posts. The diameters of the two hinge pins gradually increase in an inclined manner from the free end to the fixed end. The inner diameter of the hinge hole is adapted to the diameter of the two hinge pins. After the free ends of the two hinge pins are fixedly connected, the surfaces of the two hinge pins abut against the inner wall surface of the hinge hole to increase the damping of the pivot hinge.
[0007] As a preferred embodiment of the joint assembly of the support, each of the two hinged columns is provided with a fixing hole that passes through the corresponding support arm. After the fixing bolt passes through the two fixing holes in sequence, the free ends of the two hinged columns are fixed to each other.
[0008] As a preferred embodiment of the joint assembly of the support, the free ends of the two hinge posts extend toward each other to form positioning protrusions. After the two hinge posts are fixed, the two positioning protrusions abut against the free ends of the corresponding hinge posts, and one side of the two positioning protrusions abuts against each other.
[0009] As a preferred embodiment of the joint assembly of the bracket, the joint assembly of the bracket further includes: a decorative cover; the outer side of the bracket arm is recessed inward at the position corresponding to the fixing perforation to form a mounting groove, the inner side of the decorative cover extends inward to form a fixing protrusion ring, and the fixing protrusion ring is embedded in the mounting groove for fixation.
[0010] As a preferred embodiment of the joint assembly of the support, the joint assembly of the support further includes: a damping torsion spring, the damping torsion spring comprising: two torsion spring bodies, both ends of the two torsion spring bodies extending outward to form snap-fit ends, the two torsion spring bodies being connected through the snap-fit ends located on the same side; the two ends of the hinge through-hole extending outward to form torsion spring sleeves, the two torsion spring bodies being respectively fitted onto the torsion spring sleeves on both sides of the hinge through-hole, one of the snap-fit ends of the two torsion spring bodies extending into the hinge joint for snap-fit, and the other extending into the rotating head for snap-fit.
[0011] As a preferred embodiment of the joint assembly of the support, the hinge joint is provided with a fixing post, and the snap-fit ends on one side of the two torsion spring bodies hook and snap onto the fixing post; the rotating head is provided with snap-fit grooves on both sides, and the snap-fit ends on the other side of the two torsion spring bodies hook onto the corresponding snap-fit grooves.
[0012] As a preferred embodiment of the joint assembly of the support, the rotating head is provided with a fixing groove, and one of the two hinge columns is provided with a limiting groove at the position corresponding to the fixing groove. The limiting bolt passes through the fixing groove and extends into the limiting groove and can slide in the limiting groove. One end of the limiting bolt abuts against the groove wall at one end of the limiting groove to limit the rotation angle of the rotation.
[0013] As a preferred embodiment of the joint assembly of the support, the joint assembly of the support further includes: two support tubes; both sides of the hinge joint and the free end of the rotating head are hollowed out to form elastic buckles, and the two support tubes are provided with locking interfaces at the positions corresponding to the elastic buckles.

[0015] A stent comprising at least one articulated component of a stent as described in any of the preceding claims.
[0016] The beneficial effects of this utility model are: This utility model provides a joint assembly and a support for a bracket, comprising: a hinge joint and a rotating head. The hinge joint includes: two mutually fixed semi-hinged joints, each with a support arm at one end; and a hinge arm at one end of the rotating head, extending into the space between the two support arms. The inner sides of the two support arms extend inward to form hinge posts, each with a hinge through-hole. The free ends of the two hinge posts extend into the hinge through-hole from both sides and abut against each other, thus pivotally connecting the hinge arms to the two support arms via the two hinge posts. The diameters of the two hinge posts gradually increase in an inclined manner from the free end to the fixed end. The inner diameter of the hinge through-hole matches the diameter of the two hinge posts. After the free ends of the two hinge posts are fixedly connected, the surfaces of the two hinge posts press against the inner wall surface of the hinge through-hole to increase the damping of the pivotal hinge. The above scheme uses a pivot hinge between the hinge arm of the rotating head and the two hinge pins of the hinge joint. The diameter of the two hinge pins gradually increases from the free end to the fixed end at an incline. Compared with the traditional damping shaft, this not only increases the contact area generated by damping during rotation and increases the magnitude of rotational damping, but also increases the vertical pressure between the surfaces of the two hinge pins and the inner wall of the hinge perforation due to the increased contact area at an incline. This further increases the magnitude of rotational damping and improves the service life of the joint components of the support, which is conducive to the promotion of the support.

Detailed Implementation
[0018] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0019] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a rotatable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0020] In daily life, stands can be used to mount various tools, such as microphones, cameras, or lamps. Since these tools need to be adjusted according to various usage environments, rotating joints are installed on the stands so that the stands themselves can change their angle, thereby causing the tools to change their placement angle.
[0021] In the prior art, the adjustment of the joint components of the support is achieved through a damping shaft. That is, one end of the two support arms is provided with a hinged support, and the other end is provided with a hinged arm. The hinged arm extends into the hinged support and is pivotally hinged to the hinged support. The adjustment of the joint components of the support is achieved through the damping shaft that is pivotally hinged.
[0022] However, after repeated use, the damping shaft of the joint components of the stent may become loose. If the damping shaft is not tightened in time, the function of adjusting the rotation angle of the joint components of the stent will fail, reducing the service life of the joint components of the stent and hindering the promotion of the stent.
[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, Embodiment 1 of this utility model provides a joint assembly 100 for a bracket, which includes: a hinge joint 10, a rotating head 20, a damping torsion spring 30, a decorative cover 40, and two support tubes 50. The hinge joint 10 includes: two mutually fixed semi-hinge joints 11, one end of each of the two semi-hinge joints 11 is provided with a bracket arm 111, the decorative cover 40 is respectively embedded on the outside of the two bracket arms 111, one end of the rotating head 20 is provided with a hinge arm 21, the hinge arm 21 extends into the space between the two bracket arms 111, the damping torsion spring 30 is sleeved on both sides of the hinge arm 21, one end of which is fixed inside the hinge joint 10, and the other end of which is fixed inside the rotating head 20. The two support tubes 50 are respectively installed on the free ends of the hinge joint 10 and the rotating head 20 for connection, fixation and support. Both of the two support arms 111 extend inward to form hinge posts 112. The hinge arm 21 is provided with a hinge hole 211. The free ends of the two hinge posts 112 extend into the hinge hole 211 from both sides and abut against each other, so that the hinge arm 21 is pivotally hinged to the two support arms 111 through the two hinge posts 112. The diameters of the two hinge posts 112 gradually increase in an inclined manner from the free end to the fixed end. The inner diameter of the hinge hole 211 is adapted to the diameter of the two hinge posts 112. After the free ends of the two hinge posts 112 are fixedly connected, the surfaces of the two hinge posts 112 are pressed against the inner wall surface of the hinge hole 211 to increase the damping of the pivot hinge.
[0024] In this utility model, the above-mentioned solution is adopted, in which the hinge arm 21 of the rotating head 20 is pivotally hinged to the two hinge posts 112 of the hinge joint 10, and the diameter of the two hinge posts 112 gradually increases from the free end to the fixed end in an inclined manner. Compared with the traditional damping shaft, this not only increases the contact area generated by damping during the damping rotation and increases the magnitude of rotational damping, but also increases the vertical pressure between the surface of the two hinge posts 112 and the inner wall surface of the hinge through hole 211 due to the increased contact area being inclined, further increasing the magnitude of rotational damping and further improving the service life of the joint assembly 100 of the bracket, which is conducive to the promotion of the bracket.
[0025] like Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, in order to fix the free ends of the two hinge columns 112, each of the two hinge columns 112 is provided with a fixing hole 1121 that passes through the corresponding support arm 111. After the fixing bolt passes through the two fixing holes 1121 in sequence, the free ends of the two hinge columns 112 are fixedly connected to each other.
[0026] To position and install the two semi-hinged joints 11, the free ends of the two hinge posts 112 extend toward each other to form positioning protrusions 1122. After the two hinge posts 112 are fixed, the two positioning protrusions 1122 abut against the free ends of the corresponding hinge posts 112, and one side of the two positioning protrusions 1122 abut against each other, thereby facilitating the positioning and installation of the two semi-hinged joints 11 and making the installation of the two semi-hinged joints 11 convenient and quick.
[0027] To avoid exposing the fixing bolts, the outer side of the support arm 111 is recessed inward at the position corresponding to the fixing through hole 1121 to form a mounting groove 1111. The inner side of the decorative cover 40 extends inward to form a fixing protrusion 41. The fixing protrusion 41 is embedded in the mounting groove 1111 for fixation. Thus, the decorative cover 40 covers the fixing bolts, further enhancing the aesthetic appeal of the joint assembly 100 of the support.
[0028] To install the damping torsion spring 30, the damping torsion spring 30 includes: two torsion spring bodies 31, both ends of which extend outward to form snap-fit ends 32, and the two torsion spring bodies 31 are connected by the snap-fit ends 32 located on the same side; the two ends of the hinge through hole 211 extend outward to form torsion spring sleeves 2111, and the two torsion spring bodies 31 are respectively sleeved on the torsion spring sleeves 2111 on both sides of the hinge through hole 211. One of the snap-fit ends 32 at both ends of the two torsion spring bodies 31 extends into the hinge joint 10 for snap-fit, and the other extends into the rotating head 20 for snap-fit, thereby installing the damping torsion spring 30 between the hinge joint 10 and the rotating head 20 to further increase the damping effect of rotation.
[0029] To fix both ends of the damping torsion spring 30, a fixing post 12 is provided inside the hinge joint 10, and the snap-fit ends 32 on one side of the two torsion spring bodies 31 hook onto the fixing post 12; the rotating head 20 is provided with snap-fit grooves 22 on both sides, and the snap-fit ends 32 on the other side of the two torsion spring bodies 31 hook onto the corresponding snap-fit grooves 22, thereby fixing both ends of the damping torsion spring 30 in the hinge joint 10 and the rotating head 20 respectively, thereby enhancing the damping effect of rotational damping.
[0030] To limit the rotation angle between the rotating head 20 and the hinge joint 10, the rotating head 20 is provided with a fixed through groove 23, and one of the two hinge columns 112 is provided with a limiting groove 1123 at the position corresponding to the fixed through groove 23. The limiting bolt passes through the fixed through groove 23 and extends into the limiting groove 1123 and can slide in the limiting groove 1123. One end of the limiting bolt abuts against the groove wall at one end of the limiting groove 1123 to limit the rotation angle.
[0031] In this utility model, the rotation angle between the rotating head 20 and the hinge joint 10 is preferably less than or equal to 30°. However, this is not limited to this utility model. The range of the rotation angle between the rotating head 20 and the hinge joint 10 is determined according to the specific application. The limiting groove 1123 and the limiting bolt cooperate with each other to limit the rotation angle between the rotating head 20 and the hinge joint 10. This utility model does not impose any limitations on this.
[0032] To install the two support tubes 50, both sides of the free ends of the hinge joint 10 and the rotating head 20 are hollowed out to form elastic buckles 13 and 24. The two support tubes 50 are provided with locking interfaces 51 at the positions corresponding to the elastic buckles. After the two support tubes 50 are sleeved on the corresponding hinge joint 10 and rotating head 20, the elastic buckles 13 and 24 engage with the corresponding locking interfaces 51, so that the two support tubes 50 can be detachably installed on the corresponding hinge joint 10 and rotating head 20.
[0033] For wiring of the joint assembly 100 of the bracket, a first wiring groove 14 is provided on one side of the hinge joint 10, which connects the inside of the support tube 50 with the external space. A second wiring groove 25 is provided on one side of the rotating head 20, which connects the inside of the support tube 50 with the external space. The two ends of the power supply located in the external space are connected to the corresponding support tube 50 through the first wiring groove 14 and the second wiring groove 25, thereby allowing the power line to pass through the joint assembly 100 of the bracket.
[0034] like Figure 11 As shown, the present invention also provides a bracket, which includes at least one joint assembly 100 of the bracket as described above.
[0035] The present invention has been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and alterations to these embodiments can be made without departing from the principles and spirit of the present invention, and these changes still fall within the protection scope of the present invention.
