Description

Monitor and its lifting base

technical field

The invention relates to a display, in particular to a height-adjustable display.

Background technique

Liquid crystal display has become the mainstream display device in electronic products. The main advantage of liquid crystal display is that it is smaller in size and lighter in weight than traditional cathode ray vacuum tube display. At present, many people install the liquid crystal display on the lifting base, so that the height of the liquid crystal display can be adjusted according to the preference of the user and the difference in viewing angle.

Please refer to FIG. 1 , which is a three-dimensional view of a traditional lifting base. The display is erected on the top plate 105 , and the base body 101 is hollow so that the elevating rod 103 is accommodated in the base body 101 . The seat body 101 is provided with a spring 107 with a certain force. One end of the constant force spring 107 is fixed to the base body 101 , and the other end is fixed to the lifting rod 103 . The constant force spring 107 is used to provide a resistance to resist the gravity of the display. Assume that the weight of the display is W, and the elastic force of the constant force spring 107 is F. When W is greater than F, the lifting rod 103 will descend to a balanced state. And when F is greater than W, the lifting rod 103 will rise to another equilibrium state. Therefore, if a user has adjusted the height of the lifting base according to his own preferences and viewing angles, when the display is mounted on its top plate 105, it is likely that the lifting rod 103 will be damaged due to the weight of the display being greater than or less than the elastic force of the constant force spring. The height cannot reach the height that the user originally hoped to achieve, which causes more troubles for the user to use.

Contents of the invention

In view of this, the purpose of the present invention is to provide a display and its lifting base, so that the user can adjust the height according to his needs, and the display can also be precisely adjusted to the user's desired position.

According to the purpose of the present invention, a display is proposed, including: a display body and a lifting base. The lifting base is fixedly connected to the display body, and the lifting base includes: a base, a lifting mechanism, an outer sleeve, an inner sleeve and a friction ring. The lifting mechanism is connected to the base. The outer sleeve is connected to the base and sleeved on the outside of the lifting mechanism. The inner sleeve is embedded in the outer sleeve. The friction ring is arranged between the outer sleeve and the inner sleeve. Wherein when the height of the lifting mechanism is adjusted, the friction ring provides a frictional force between the outer sleeve and the inner sleeve to fix the height of the lifting mechanism.

According to the purpose of the present invention, a lifting base of a display is further proposed, which includes: a base, a lifting mechanism, an outer sleeve, an inner sleeve and a friction ring. The lifting mechanism is connected to the base. The outer sleeve is connected to the base and sleeved outside the lifting mechanism, and the inner sleeve is embedded in the outer sleeve.

Detailed ways

Please refer to FIG. 2A and FIG. 2B at the same time. FIG. 2A is a perspective view of the display, and FIG. 2B is an exploded view of the lifting base. The display 200 includes: a display body 201 and a lifting base 203 . The lifting base 203 is fixedly connected to the display body 201 . The lifting base 203 includes: a base 205 , a lifting mechanism 207 (shown in FIG. 2B ), an outer sleeve 209 , an inner sleeve 211 , a friction ring 213 and a fixing portion 217 . The base 205 is used to bear the weight of the display body 201 and the lifting base 203 . Through the fixing portion 217 , the lifting base 203 can be fixedly connected to the inner sleeve 211 and the display body 201 . As shown in FIG. 2B , the lifting mechanism 207 includes: a base body 220 , a lifting rod and an elastic element 224 , and the lifting rods are, for example, a first lifting rod 222 a and a second lifting rod 222 b. The seat body 220 has at least one accommodating opening, such as a first accommodating opening 226a and a second accommodating opening 226b. The first lifting rod 222a and the second lifting rod 222b are movably disposed in the first accommodating opening 226a and the second accommodating opening 226b correspondingly. The elastic element 224 is preferably a constant force spring, one end of which is fixed to the base body 220 and the other end is fixed to the lifting rod to provide a restoring force against the weight of the display body 201 . Of course, the lifting rod is not limited to two rods, as long as it can support and adjust the height.

However, only the elastic element 224 is configured to resist the weight of the display body 201 , but the height of the lifting base 203 cannot be precisely controlled due to the tolerance of the elastic element. Therefore, in this embodiment, the friction ring 213 is configured so that the user can control the height of the lifting base 203 more precisely. Please refer to FIG. 3A , which shows a perspective view of the friction ring. The friction ring 213 has an inner bump and a guide block, and the inner bump is, for example, a first inner bump 231a and a second inner bump 231b. The guide blocks are, for example, the first guide block 233a and the second guide block 233b (shown in FIG. 4 ). A first opening 235a and a second opening 235b are defined on both sides of the first inner bump 231a and the second inner bump 231b. The first opening 235a and the second opening 235b are used to provide the deformation space of the first inner convex point 231a and the second inner convex point 231b, for example, the first inner convex point 231a and the second inner convex point 231b are compressed from the directions A1 and A2. The first opening 235a and the second opening 235b, the first inner protrusion 231a and the second inner protrusion 231b can move in directions A1' and A2' respectively.

Please refer to FIG. 3B , which shows a perspective view of the outer sleeve. The outer sleeve 209 includes: a guide rail 243 and an outer convex point. The outer bumps are, for example, the first outer bumps 241a and the second outer bumps 241b. The guide rail 243 is formed around the inner diameter of the outer sleeve 209 . Please refer to FIG. 3C and FIG. 4 , FIG. 3C shows a perspective view when the outer sleeve and the friction ring are separated, and FIG. 4 shows a perspective view when the outer sleeve and the friction ring are combined. When the engaging friction ring 213 is inside the outer sleeve 209 , the first guide block 233 a and the second guide block 223 b can slide in the guide rail 243 . Therefore, when the friction ring 213 is rotated, the first guide block 233a and the second guide block 233b then move along the guide rail 243, and when the first inner convex point 231a is close to the first outer convex point 241a, the first outer convex point 241a will be Compressing the first inner convex point 231a makes the first inner convex point 231a move inward. Similarly, the second outer bump 241b compresses the second inner bump 231b and moves inward. The first inner convex point 231a and the second inner convex point 231b pressed inward will resist the inner sleeve 211 (drawn in FIG. 2B ) to provide frictional force to the inner sleeve 211, and prevent the lifting base 203 from moving. altitude change.

The display and its base disclosed in the above-mentioned embodiments of the present invention can be used in different displays such as liquid crystal displays, plasma displays and vacuum tube displays. Through the friction force provided by the friction ring, users can precisely adjust the height of the display according to their needs and viewing angles, thereby increasing the core value of the product.

In summary, although the present invention has been disclosed in conjunction with the above preferred embodiment, it is not intended to limit the present invention. Any person familiar with the art can make various changes without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be defined by the claims.
