Screen bracket

This creation is about screen holders, especially a screen holder that is resistant to high loads.

Conventional screen brackets generally have a hinge for a fixed posture. The hinges of the hinges are often used as a damping function by the springs, and can use the elasticity of the spring to generate a reaction force or utilize the frictional force to generate a damping effect. A common practice is to press the hinge, for example, with a spring along the axial direction of the hinge, and a frictional force is generated between the hinge and the hinge by pressing the hinge at both ends of the spring. This method can be applied to a lightly loaded mechanism such as a mobile phone or a notebook computer. However, if it is used in a large screen, it is not enough to rely on the friction generated by the ends of the spring.

The purpose of the present invention is to provide a high-load-resistant screen support that generates friction by the friction inside the coil spring.

In order to achieve the above object, the present invention provides a screen bracket for arranging a screen on a fixture comprising a clamp, a link and a pivot structure. A clamp is used to clamp the fixture. One end of the connecting rod is connected to the screen, and the other end is pivotally connected to the clamp. The pivot structure includes a rotating shaft, a coil spring and a sleeve. The rotating shaft comprises a fixing section and a receiving section extending from the fixing section, the outer diameter of the fixing section is larger than the outer diameter of the receiving section, the connecting section is connected with the connecting rod, one end of the coil spring is sleeved on the fixing section, and the other end of the coil spring The extension cover is disposed outside the receiving section, the sleeve is rotatably sleeved on the receiving section and connected to the clamp, and the coil spring is wrapped around the outer edge of the sleeve.

Preferably, in the foregoing screen bracket, the sleeve is a hollow cylinder with two ends open.

Preferably, in the foregoing screen bracket, the coil spring is a cylindrical coil spring.

Preferably, in the foregoing screen bracket, the coil spring is a variable diameter coil spring.

Preferably, in the foregoing screen bracket, the fixing section is tightly fixed by the interference of the coil spring.

Preferably, in the foregoing screen holder, the coil spring has a tightening direction in the circumferential direction, and when the coil spring is twisted in the tightening direction, the inner diameter of the coil spring is reduced, and the coil spring is generated in the opposite direction to the tightening direction. A counter torque.

Preferably, in the foregoing screen bracket, when the sleeve rotates in the tightening direction with respect to the rotating shaft, the sleeve rotates the coil spring in the tightening direction by the static friction between the sleeve and the inner side of the coil spring, so that the coil spring is inside The diameter is reduced and the sleeve is forced.

Preferably, in the foregoing screen bracket, the coil spring is rotated by the sleeve and continues to twist in the tightening direction with respect to the rotating shaft. When the static friction force is maximized and the torque is less than the counter torque, the coil spring is released from the sleeve and returns without Load status.

Preferably, the aforementioned screen bracket has a socket formed in the fixing portion thereof, and the coil spring includes a plug portion that is inserted into the socket to fix the coil spring to the fixing portion.

Preferably, in the foregoing screen bracket, the coil spring is fixed to the fixed section.

Preferably, in the foregoing screen bracket, the outer diameter of the fixing section is slightly larger than the inner diameter of the coil spring, so that the coil spring is tightly fixed to the fixing section.

Preferably, the foregoing screen bracket further comprises a screen connecting member connected to the screen and pivoting the connecting rod to pivot the connecting rod to the screen.

Preferably, the aforementioned screen bracket, wherein the connecting rod comprises a second connecting member, the clamp comprises a first connecting member, the second connecting member is coupled to the rotating shaft, and the first connecting member is coupled to the sleeve.

Since the screen bracket of the present invention uses the inner side of the coil spring to force the sleeve to generate frictional force to achieve the effect of resisting mud, compared with the prior art, only the two ends of the spring are used to resist the friction of the hinge, and the screen bracket of the present invention is created. The resulting friction is much greater than conventional techniques and can withstand greater loads.

Referring to the first to third embodiments, a preferred embodiment of the present invention provides a screen holder for placing a screen 10 on a fixture (for example, a table), comprising: a clamp 100 and a link 200. A screen connector 201 and a pivot structure 300.

The clamp 100 is used for clamping a fixture, and the clamp 100 includes a first connector 110. The first connector 110 is bent from a metal piece, and has a U-shape and two side plates 101/102. A first opening 111 and a shaft hole 112 are disposed on the two side plates 101/102 respectively.

One end of the connecting rod 200 is pivotally connected to the screen connecting member 201, and the other end is provided with at least one second connecting member 210. The screen connecting member 201 locks the screen 10 to pivot the connecting rod 200 to the screen 10. In the present embodiment, the second connecting member 210 is preferably included. The second connecting member 210 is a metal piece. The second opening 211 is formed in a shape that is not circular.

The pivot structure 300 includes a rotating shaft 310, a coil spring 320 and a sleeve 330. The rotating shaft 310 includes a fixing portion 311 and a receiving portion 312 extending from the fixing portion 311. The outer diameter of the fixing portion 311 is larger than the outer diameter of the receiving portion 312, and the shaft hole 112 is sleeved on the fixed end portion 311. The two ends of the rotating shaft 310 extend from the ends of the fixing portion 311 and the receiving portion 312 respectively to form a rotating shaft connecting end 313. The radial cross-section of the two rotating shaft connecting ends 313 is preferably not circular. The radial cross-sectional shape of the rotating shaft connecting end 313 conforms to the second opening 211, and the rotating shaft connecting end 313 penetrates into the second opening 211, so that the second connecting member 210 and the rotating shaft 310 are supported to rotate circumferentially relative to each other. On each of the rotating shaft connecting ends 313, a nut 103 is respectively locked on the outer side of the second connecting member 210 to prevent the second connecting member 210 from coming out along the axial direction of the rotating shaft 310, and the second connecting member 210 is fixedly connected to the second connecting member 210. On the rotating shaft 310. Preferably, a gasket 104 is interposed between the nut 103 and the second connecting member 210.

The coil spring 320 is preferably a cylindrical coil spring (the present invention is not limited thereto, for example, a variable diameter coil spring having a different inner diameter of the two ends), and is coaxially sleeved outside the rotating shaft 310, preferably fixed. The outer diameter of the segment 311 is slightly larger than the inner diameter of the coil spring 320, and one end of the coil spring 320 is interfered with the fixed portion 311 to fix the coil spring 320 outside the fixed portion 311 (this creation does not limit the need to be tightly fixed) The outer diameter of the fixed section 311 may also be approximately equal to the inner diameter of the coil spring 320, and the other end is extended outside the receiving section 312 (if it is a variable diameter coil spring, one end of the smaller radius of the coil spring 320 and the fixed section) The 311 is forced to be fixed outside the fixed section 311, and the other end is extended outside the receiving section 312.

The coil spring 320 has a tightening direction in the circumferential direction. For example, when it is coaxially sleeved on the rotating shaft 310, the right-handed spring is spirally extended clockwise from the fixing section 311 along the axial direction of the rotating shaft 310 toward the rotating shaft connecting end 313. The clockwise direction of the self-fixing section 311 in the axial direction toward the shaft connecting end 313 is the tightening direction (the tightening direction of the left-handed spring is counterclockwise), and when the coil spring 320 is applied with a torque and twisted in the tightening direction, The inner diameter of the coil spring 320 is reduced and a counter torque is generated opposite to the tightening direction. When the coil spring 320 is twisted against the tightening direction, the inner diameter of the coil spring 320 is enlarged. Preferably, the tightening direction of the coil spring 320 is set to be the same as the torque direction formed by the weight of the screen 10 to the pivot structure.

The sleeve 330 is preferably a hollow cylinder having a two-end opening, the inner diameter of which is not smaller than the outer diameter of the receiving portion 312, and the outer diameter thereof is approximately equal to the inner diameter of the coil spring 320 (preferably, the outer diameter of the fixed portion 311 is slightly larger than The outer diameter of the sleeve 330, but the present creation is not limited thereto. One end of the sleeve 330 is a sleeve connecting end 331. The radial cross section of the sleeve connecting end 331 is preferably not circular and conforms to the first opening 111. The first opening 111 is sleeved on the sleeve connecting end 331. The first connecting member 110 and the sleeve 330 are supported to rotate in the circumferential direction. The sleeve 330 is rotatably sleeved on the bearing section 312 with respect to the rotating shaft 310 and located between the inner side of the coil spring 320 and the receiving section 312. The coil spring 320 extends from the fixing section and is wrapped around the outer edge of the sleeve 330. The outer surface of the sleeve 330 is brought into contact with the inner side of the coil spring 320.

Referring to the fourth and fifth figures, when the screen 10 provides a gravity such that the sleeve 330 rotates relative to the rotating shaft 310 along the tightening direction of the coil spring 320, between the sleeve 330 and the inside of the coil spring 320 Static friction, the sleeve 330 drives the coil spring 320 to twist in the tightening direction while applying a torque to the coil spring 320. The inner diameter of the coil spring 320 is reduced to tighten the sleeve 330, preventing the sleeve 330 from being tightened. The direction is rotated with respect to the rotating shaft 310, and the position of the link 200 is fixed.

When the screen 10 is pushed downward to cause the sleeve 330 to continue to rotate in the tightening direction relative to the rotating shaft 310, the static friction force is maximized to provide a torque less than the counter torque generated by the coil spring 320, the coil spring 320 is disengaged from the sleeve 330. Driven back to no load. When the coil spring 320 returns to the unloaded state, its counter torque disappears, and the sleeve 330 again drives the coil spring 320 to twist in the tightening direction by the static friction force to press the sleeve 330. When the screen 10 is pushed upward, the sleeve 330 drives the coil spring 320 to twist the coil spring 320 against the tightening direction, so that the inner diameter of the coil spring 320 is enlarged, and the friction between the coil spring 320 and the sleeve 330 is reduced. promote.

The screen bracket of the present invention increases the contact area by increasing the contact area with the inner side of the coil spring 320 to increase the frictional force, thereby increasing the contact area of the inner side of the coil spring 320 and the sleeve 330. The contact area between the two ends of the technical coil spring and the hinge is such that the frictional force generated by the pivotal structure of the screen holder is much larger than that of the conventional technology, and thus the load resistance is also high.
