Description

Technical Field

[0001] This utility model relates to the field of brackets, specifically to a dual-purpose bracket for a desk lamp and a mobile phone. Background Technology

[0002] Currently, the lower end of the bracket connects to the base, and the upper end connects to the lamp body or phone holder. To adjust the illumination direction, screen orientation, or camera shooting direction, the bracket incorporates a joint structure, allowing the lamp body or phone holder to adjust its angle relative to the base. Existing joint structures include a movable joint and a fixed joint. Bolts are passed through the movable and fixed joints, and tightening the bolts to a certain degree causes the bolts to axially clamp the movable and fixed joints. Therefore, it is necessary to manually overcome the friction between the movable and fixed joints to allow them to swing relative to each other. In other words, the movable joint... The fixed joint achieves relative stillness through static friction between the two. However, after a period of use, the bolts may loosen, which will significantly reduce the static friction. This will cause the relative angle between the moving joint and the fixed joint to creep easily, or even cause the moving joint and the fixed joint to loosen and fail to support the weight of the lamp body or mobile phone, thus failing to achieve the effect of adjusting the angle. Alternatively, after a period of use, the friction surfaces of the moving joint and the fixed joint may wear, also causing the moving joint and the fixed joint to loosen. Therefore, the existing bracket technology has problems with insufficient durability and poor angle positioning effect, and it is necessary to improve it. Summary of the Invention

The joint assembly includes a fixed joint and a movable joint. The fixed joint forms a fixed hinge joint, and the movable joint forms a movable hinge joint. The fixed hinge joint is hinged to the movable hinge joint via a hinge shaft. The movable hinge joint forms a circumferential positioning tooth groove, which is circumferentially distributed around the hinge shaft. A locking pin is slidably connected to the fixed joint. One end of the locking pin engages with the corresponding circumferential positioning tooth groove. A compression spring is provided within the fixed joint for pushing the locking pin into the circumferential positioning tooth groove, and one end of the compression spring is connected to the locking pin.

[0006] Preferably, the circumferential positioning groove is an arc-shaped groove, and one end of the chuck is formed with a ball needle tip that is adapted to the circumferential positioning groove.

Detailed Implementation

[0021] The present invention will now be further described with reference to the accompanying drawings.

[0022] The bracket of this utility model, such as Figures 1 to 3 As shown, the device includes a rod 1, with a joint assembly 4 connected to the end of the rod 1. The joint assembly 4 includes a fixed joint 41 and a movable joint 42. The fixed joint 41 forms a fixed hinge joint 412, and the movable joint 42 forms a movable hinge joint 422. Figure 4 As shown, the fixed hinge joint 412 is hinged to the movable hinge joint 422 via the hinge shaft 47. It should be noted that only... Figure 4 The hinge shaft 47 is schematically drawn. For example, one end of the hinge shaft 47 forms a head, and the corresponding other end of the hinge shaft 47 is screwed with a nut, such as... Figure 3 As shown, the fixed hinge joint 412 has a fixed hinge hole 4121, and the movable hinge joint 422 has a movable hinge hole 4221. The hinge shaft 47 passes through the fixed hinge hole 4121 and the movable hinge hole 4221. The movable hinge joint 422 and the fixed hinge joint 412 (in the axial direction of the hinge shaft 47) are positioned between the head of the hinge shaft 47 and the nut. Thus, the movable joint 42 can swing relative to the fixed joint 41 about the axis of the hinge shaft 47 (that is, the "fixed" in the fixed joint 41 is relative to the movable joint 42). Figures 3 to 5 As shown, the movable hinge joint 422 has a circumferential positioning tooth groove 4201, which is circumferentially distributed around the hinge axis 47. The circumferential positioning tooth grooves 4201 can be evenly spaced. A locking pin 43 is slidably connected to the fixed joint 41. One end of the locking pin 43 engages with the corresponding circumferential positioning tooth groove 4201. The fixed joint 41 is provided with a compression spring 46 for pushing the locking pin 43 into the circumferential positioning tooth groove 4201. One end of the compression spring 46 is connected to the locking pin 43. Figure 4As shown, since one end of the locking pin 43 engages with the corresponding circumferential positioning groove 4201, and the elastic restoring force of the compression spring 46 is applied to the circumferential positioning groove 4201 through the locking pin 43, the locking pin 43 prevents the movable joint 422 from swinging around the hinge axis 47. The relative angle between the movable joint 42 and the fixed joint 41 can be stably maintained, that is, the movable joint 42 and the fixed joint 41 are not prone to relative creeping swing. Therefore, the angular positioning effect of the movable joint 42 and the fixed joint 41 of this utility model is better. Since the swing resistance of the movable joint 42 is not mainly provided by the friction between the movable joint 42 and the fixed joint 41, but by the chuck 43 directly blocking the movable joint 422 in the swing tangential direction of the movable joint 422, the combination structure of the chuck 43 and the circumferential positioning tooth groove 4201 enables the movable joint 42 to be positioned relative to the fixed joint 41 in the circumferential direction of the hinge shaft 47. The concave-convex matching structure of the chuck 43 and the circumferential positioning tooth groove 4201 has low sensitivity to wear (compared to the prior art), so it has good durability.

[0023] When it is necessary to swing the movable joint 42 relative to the fixed joint 41, the movable joint 42 is swung by hand, causing the edge of the groove of the circumferential positioning tooth groove 4201 to push open the locking pin 43, so that the locking pin 43 slides relative to the fixed joint 41. Under the drive of the locking pin 43, the compression spring 46 is further elastically compressed and deformed, so that the locking pin 43 can pass over the groove of the circumferential positioning tooth groove 4201. When the locking pin 43 reaches an adjacent circumferential positioning tooth groove 4201, the elastic restoring force of the compression spring 46 pushes the locking pin 43 into the circumferential positioning tooth groove 4201. In this way, the movable joint 42 can complete the angle adjustment.

[0024] like Figure 1 As shown, for example, the bracket of this utility model has two rods 1 and three joint components 4. The rods 1 can be hollow rods, such as... Figures 1 to 3 As shown, (in the vertical direction) a fixed plug 411 is formed at the lower end of the fixed joint 41 of the middle joint assembly 4. The fixed plug 411 is integrated with the fixed hinge joint 412. The fixed plug 411 is inserted into the upper end of the lower rod 1. A movable plug 421 is formed at the upper end of the movable joint 42 of the middle joint assembly 4. The movable plug 421 is integrated with the movable hinge joint 422. The movable plug 421 is inserted into the lower end of the upper rod 1. Figure 1 As shown, the lower end of the movable joint 42 of the joint assembly 4 located in the lower position has a lower connecting portion 2 for inserting into the base 99, and the upper end of the fixed joint 41 of the joint assembly 4 located in the lower position is inserted into the lower end of the rod 1 located in the lower position; as shown Figure 1As shown, the upper end of the movable joint 42 of the joint assembly 4 in the upper position is formed with an upper connecting part 3 for connecting the mobile phone clamp 97 or the lamp body 98, and the lower end of the fixed joint 41 of the joint assembly 4 in the upper position is inserted into the upper end of the rod body 1 in the upper position; thus, the support of the utility model can realize three-axis swing positioning, and thus the mobile phone clamp 97 or the lamp body 98 can be translated and positioned, so that the positioning function is relatively rich.

[0025] Figure 7 The application of the lower connecting part 2 inserted into the base 99 and the upper connecting part 3 inserted into the mobile phone clamp 97 is shown by way of example, Figure 8 The application of the lower connecting part 2 inserted into the base 99 and the upper connecting part 3 hinged to the lamp body 98 is shown by way of example.

[0026] Further, as shown in Figure 4 and Figure 5 , the circumferential positioning tooth groove 4201 is provided as a circular arc tooth groove, that is, the bottom of the circumferential positioning tooth groove 4201 is in an arc shape, as shown in Figure 3 and Figure 4 , one end of the clamping needle 43 is formed with a ball needle head 431 matched with the circumferential positioning tooth groove 4201, so that the ball needle head 431 and the circumferential positioning tooth groove 4201 can be well matched, which is conducive to the stable clamping of the ball needle head 431 to the circumferential positioning tooth groove 4201, and specifically, the ball needle head 431 can be formed with a hemispherical surface, and the radius of the hemispherical surface is equal to the radius of the bottom of the circumferential positioning tooth groove 4201, as shown in Figure 4 , so that when the movable joint 42 is swung and positioned by hand, the groove edge part of the circumferential positioning tooth groove 4201 can be relatively easily slid to the top end of the ball needle head 431 guided by the ball needle head 431, thereby reducing the jamming during the swing and positioning of the movable joint 42.

[0027] Further, as shown in Figure 5 , the circumferential positioning tooth groove 4201 is axially single-sidedly penetrated through the movable hinge joint 422, that is, in the direction parallel to the axis of the hinge shaft 47, one side of the circumferential positioning tooth groove 4201 is formed with a tooth groove side wall 4202, and the other side of the circumferential positioning tooth groove 4201 is provided as an open structure, and the adjacent tooth groove side walls 4202 are integrally connected, thus being conducive to increasing the structural strength of the circumferential positioning tooth groove 4201 and avoiding the circumferential positioning tooth groove 4201 being easily damaged to cause unstable clamping of the circumferential positioning tooth groove 4201 to the ball needle head 431.

[0028] Further, as shown in Figure 3 , the fixed hinge joint 412 is formed with an axial positioning groove 4122, as shown in Figure 1 , the movable hinge joint 422 is inserted into the axial positioning groove 4122, as shown in Figure 2 and Figure 3As shown, the movable hinge joint 422 is inserted into the axial positioning groove 4122 along the radial direction of the hinge shaft 47, that is, in the axial direction of the hinge shaft 47, the movable hinge joint 422 is blocked by the axial positioning groove 4122 when moving to both sides, and the axial positioning groove 4122 is provided with a clamping pin mounting hole 4101, as shown in Figure 3 As shown, the bottom of the axial positioning groove 4122 is provided with a clamping pin mounting hole 4101, as shown in Figure 4 As shown, the clamping pin 43 is slidingly arranged in the clamping pin mounting hole 4101, and the compression spring 46 is arranged in the clamping pin mounting hole 4101, during which the compression spring 46 can elastically stretch and contract in the clamping pin mounting hole 4101, and the other end of the clamping pin 43 is provided with a pin handle 432, and a step is formed between the pin handle 432 and the ball needle head 431, the pin handle 432 is inserted into the compression spring 46, one end of the compression spring 46 abuts against the step, and the other end of the compression spring 46 abuts against the bottom of the clamping pin mounting hole 4101, by arranging the clamping pin mounting hole 4101 at the bottom of the axial positioning groove 4122, the clamping pin 43 and the circumferential positioning tooth groove 4201 can be hidden in the axial positioning groove 4122, and the combination structure of the clamping pin 43 and the circumferential positioning tooth groove 4201 can be prevented from being easily damaged by external objects.

[0029] Further, as shown in Figure 2 and Figure 3 As shown, a gasket 44 is arranged between the inner wall of the axial positioning groove 4122 and the movable hinge joint 422, and the hinge shaft 47 passes through the gasket 44, as shown in Figure 5 As shown, the two sides (in the axial direction of the hinge shaft 47) of the movable hinge joint 422 are respectively provided with recesses 4222, and the gasket 44 is fitted into the corresponding recesses 4222, that is, the recesses 4222 are circular recesses, the recesses 4222 have a radial positioning effect on the gasket 44, the inner wall of the axial positioning groove 4122 is in contact with the gasket 44, and the gasket 44 can be made of polytetrafluoroethylene, and since the fixed joint 41 has a small friction with the gasket 44, the relative swing resistance between the fixed joint 41 and the movable joint 42 can be reduced, which is beneficial to the flexible swing positioning of the joint assembly 4.

[0030] Further, as shown in Figures 4 to 6 The joint assembly 4 is provided with a wire clamp groove 45, so that the wire can be pressed into the wire clamp groove 45, for example, the wire between the base 99 and the lamp body 98 is positioned in the wire clamp groove 45, and in the process of pressing the wire into the wire clamp groove 45, the wire clamp groove 45 can be elastically expanded to a small extent, for example, the wire clamp groove 45 can be arranged close to the end of the rod body 1, as shown in Figure 6As shown, for example, the fixed joint 41 and the moving joint 42 of the joint assembly 4 in the middle position are integrally formed with a wire clip groove 45, the fixed joint 41 of the joint assembly 4 in the lower position is integrally formed with a wire clip groove 45, and the fixed joint 41 of the joint assembly 4 in the upper position is integrally formed with a wire clip groove 45.
