Description

Technical Field

[0001] This invention relates to the field of liquid crystal display technology, specifically to a shock-resistant liquid crystal display. Background Technology

[0002] LCD screens are a common type of flat-panel display, generally used in television and computer screens. The advantages of LCD screens include low power consumption, small size, and low radiation. However, when LCD screens are used for outdoor displays or sales demonstrations, the unpredictable outdoor weather conditions pose certain safety hazards. Specifically, because LCD screens have a relatively high center of gravity and typically only have one or two support legs, they are prone to tipping over in windy conditions. Therefore, measures are needed to limit the tipping and overturning of LCD screens and prevent them from colliding with the ground and sustaining damage. This necessitates the use of impact-resistant LCD screens.

[0003] Existing impact-resistant LCD screens typically have elastic mechanisms at the bottom of the screen for added stability and safety. These mechanisms provide support and protection against damage from external environmental factors.

[0004] However, in actual use, the direction in which the LCD screen tilts or falls after being affected by wind is uncertain. Existing elastic devices, when used in conjunction with damping for protection, tend to generate stronger pulling forces in the opposite direction of the LCD screen's tilt, making it difficult for the LCD screen to return to a stationary state and affecting the display safety. In view of this, we propose an impact-resistant LCD screen. Summary of the Invention

[0005] The purpose of this invention is to provide a shock-resistant liquid crystal display screen to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a shock-resistant liquid crystal display screen, comprising a base, a connecting seat fixedly mounted on the upper surface of the base, a connecting ball rotatably mounted on the inner wall of the connecting seat, the bottom end of a support rod fixedly mounted on the top of the connecting ball, and a display screen body fixedly mounted on the top end of the support rod. A protective component is provided on the upper surface of the base, the protective component comprising:

[0007] A sliding sleeve is fitted on the outer wall of the support rod, and the end of a connecting rod is hinged to the arc-shaped outer wall of the sliding sleeve. The bottom end of the sleeve rod is hinged to the upper surface of the base.

[0008] A transmission plate is slidably installed on the inner wall of the sleeve rod. One end of a telescopic rod is fixedly connected to the side wall of the transmission plate, and the other end of the telescopic rod is fixedly connected to the side wall of a threaded slider. The end of a protective spring is fixedly connected to the side wall of the transmission plate.

[0009] A take-up roller, the end of which is rotatably mounted on the inner wall of the sleeve, a cable is wound around the arc-shaped outer wall of the take-up roller, and a guide ring is fixedly mounted on the inner wall of the sleeve.

[0010] The active bevel gear passes through the winding roller and is fixedly connected to the winding roller. An adjusting screw is rotatably installed on the inner wall of the sleeve rod, and a driven bevel gear is fixedly connected to the bottom end face of the adjusting screw.

[0011] Preferably, the connecting seat is provided with a torsion spring inside, and one end of the torsion spring is fixedly connected to the bottom spherical surface of the connecting ball, so that the display screen body can eventually return to a vertical state after being hit by external impact or affected by wind.

[0012] Preferably, the top inner wall of the connecting seat is provided with an inverted frustum-shaped groove, and the bottom inner wall of the groove is provided with a sliding groove that matches the connecting ball, so that the connecting ball can drive the support rod to deflect more and greater angles within the connecting seat.

[0013] Preferably, the outer wall of the connecting rod is square, and the inner wall of the top end of the sleeve is provided with a rectangular groove that matches the outer surface of the connecting rod. The connecting rod is slidably disposed inside the rectangular groove, so that the connecting rod can slide along the rectangular groove inside the sleeve.

[0014] Preferably, the telescopic rod is hollow inside, and the diameter of the internal cavity of the telescopic rod is larger than the outer diameter of the adjusting screw, so that the movement between the adjusting screw and the telescopic rod will not interfere with each other.

[0015] Preferably, the inner wall of the threaded slider has a through hole with a diameter that matches the outer diameter of the cable, so that the cable and the through hole inside the threaded slider can slide relative to each other without getting stuck.

[0016] Preferably, the guide ring has a channel hole at its center that matches the outer diameter of the cable, and the edge of the channel hole is rounded to avoid excessive wear on the outer surface of the cable and reduce the service life of the cable.

[0017] Preferably, a limiting ring is provided on the arc-shaped outer wall of the take-up roller to prevent the cable from moving excessively toward the driving bevel gear during take-up, thereby affecting the movement of the driving bevel gear and the driven bevel gear.

[0018] Preferably, the upper surface of the base is provided with a tensioning assembly, the tensioning assembly includes a hinge rod, the bottom end of the hinge rod is hinged to the upper surface of the base, and the top end of the hinge rod is fixedly connected to the bottom end of an elastic element.

[0019] Preferably, a positioning cavity is provided at the center of the sliding sleeve, and a positioning ball is provided inside the positioning cavity.

[0020] Compared with the prior art, the present invention provides a shock-resistant liquid crystal display screen, which has the following beneficial effects:

[0021] 1. This impact-resistant LCD screen is designed to prevent tipping and impacts caused by external environmental interference. It incorporates protective components that allow relative sliding between the connecting rod and the sleeve rod. The transmission mechanism inside the sleeve rod adjusts the deformation distance of the protective spring in that direction, ensuring it maintains good elastic protection without excessive compression. Excessive compression would prevent the conversion of elastic potential energy into kinetic energy, affecting the speed at which the screen returns to its original shape and reducing its safety.

[0022] 2. In order to ensure that the protective components can always keep the support rod in a vertically tightened state, the impact-resistant LCD screen is equipped with tensioning components that correspond one-to-one with the protective components. These components, together with elastic elements, exert a downward pulling force on the sleeve rod. When this pulling force is applied to the connecting rod and the sliding sleeve, it can better support and protect the support rod, thus ensuring the stability of the screen body.

[0023] 3. This impact-resistant LCD screen, in order to reduce excessive wear between the support rod and the sliding sleeve due to the supporting force of the protective components when the support rod tilts, has a positioning ball and a positioning cavity adapted to the positioning ball inside the sliding sleeve. This transforms the sliding friction between the support rod and the sliding sleeve into rolling friction, effectively reducing wear between the support rod and the sliding sleeve and improving the stability and service life of the device during use.

[0031] like Figure 1-6 As shown, the present invention provides a technical solution: a shock-resistant liquid crystal display screen, including a base 1, a connecting seat 2 fixedly installed on the upper surface of the base 1, a connecting ball 3 rotatably installed on the inner wall of the connecting seat 2, the bottom end of a support rod 4 fixedly installed on the top of the connecting ball 3, and a display screen body 5 fixedly installed on the top end of the support rod 4. A protective component is provided on the upper surface of the base 1, the protective component including a sliding sleeve 6, the sliding sleeve 6 is sleeved on the outer wall of the support rod 4, the end of a connecting rod 7 is hinged to the arc-shaped outer wall of the sliding sleeve 6, the bottom end of a sleeve rod 8 is hinged to the upper surface of the base 1, a transmission plate 9 is slidably installed on the inner wall of the sleeve rod 8, and a telescopic mechanism is fixedly connected to the side wall of the transmission plate 9. One end of the telescopic rod 10 and the other end of the telescopic rod 10 are fixedly connected to the side wall of the threaded slider 11. The side wall of the transmission plate 9 is fixedly connected to the end of the protective spring 12. The other end of the protective spring 12 is fixedly connected to the side wall of the threaded slider 11. The end of the take-up roller 13 is rotatably mounted on the inner wall of the sleeve rod 8. A cable 14 is wound around the arc-shaped outer wall of the take-up roller 13. A guide ring 15 is fixedly mounted on the inner wall of the sleeve rod 8. The take-up roller 13 is penetrated by a drive bevel gear 17, and the drive bevel gear 17 is fixedly connected to the take-up roller 13. An adjusting screw 18 is rotatably mounted on the inner wall of the sleeve rod 8. A driven bevel gear 19 is fixedly connected to the bottom end face of the adjusting screw 18.

[0032] In one embodiment of the present invention, the base 1 is disc-shaped and disposed at the bottom of the connecting seat 2 to increase the contact area between the base 1 and the ground. This ensures that the base 1 maintains a stable positioning effect on the ground regardless of the direction of deflection of the display screen body 5, thereby preventing the entire device from tipping over due to inertia. In addition, a torsion spring is provided inside the connecting seat 2, and one end of the torsion spring is fixedly connected to the bottom spherical surface of the connecting ball 3. This allows the torsion spring to be driven when the connecting ball 3 is subjected to the deflection force caused by the tilting of the support rod 4. This allows the torsion spring to guide the connecting ball 3 to return to its original position, ensuring that the display body 5 can eventually return to a vertical state after being impacted by external forces or affected by wind. At the same time, the top inner wall of the connecting seat 2 has an inverted frustum-shaped groove, and the bottom inner wall of the groove has a sliding groove that matches the connecting ball 3. This allows the connecting ball 3 to drive the support rod 4 to deflect at more and greater angles within the connecting seat 2, thus providing redundancy for the range where the display body 5 tilts due to external forces, and better ensuring the safety of the display body 5 in use.

[0033] In an embodiment of the present invention, a circular hole with a diameter matching the outer diameter of the support rod 4 is provided at the center of the sliding sleeve 6, and the support rod 4 passes through the circular hole. Furthermore, six sets of protective components are provided, arranged in a circular array around the center of the support rod 4. This ensures that when the support rod 4 and the display screen body 5 tilt or show a tendency to tilt due to external force, the multiple sets of protective components around the support rod 4 provide better support for the use and display safety of the display screen body 5. Simultaneously, the outer wall of the connecting rod 7 is square, and the inner wall of the top of the sleeve 8 has a rectangular groove that matches the outer surface of the connecting rod 7. Specifically, the connecting rod 7 slides inside the rectangular groove, allowing it to slide along the rectangular groove inside the sleeve 8. Further, the inner wall of the sleeve 8 has a rectangular receiving groove, and the outer surface of the transmission plate 9 is square, with the square outer surface of the transmission plate 9 matching the rectangular receiving groove, allowing the transmission plate 9 to only slide along... The sliding mechanism slides along the rectangular receiving groove. Similarly, the outer surface of the threaded slider 11 is designed to be exactly the same as that of the transmission plate 9, thereby guiding and restricting the movement of the threaded slider 11. Specifically, the threaded slider 11 can only slide horizontally along the inner wall of the rectangular receiving groove. At the same time, the telescopic rod 10 is hollow inside, and the diameter of the internal cavity of the telescopic rod 10 is larger than the outer diameter of the adjusting screw 18, so that the movement between the adjusting screw 18 and the telescopic rod 10 will not interfere with each other. Furthermore, the protective spring 12 is sleeved on the outside of the telescopic rod 10 so that the telescopic rod 10 can always guide and restrict the deformation of the protective spring 12. Specifically, when the protective spring 12 is compressed or stretched, it can only deform along the extension and retraction direction of the telescopic rod 10, and will not bend vertically under its own weight or when compressed, thereby ensuring that the protective spring 12 can always provide a stable transmission effect for the transmission plate 9.

[0034] In an embodiment of the present invention, the adjusting screw 18 is threadedly connected to the threaded slider 11, so that when the adjusting screw 18 rotates, the threaded slider 11 slides along the inner wall of the sleeve 8. Furthermore, the inner wall of the threaded slider 11 has a through hole with a diameter matching the outer diameter of the cable 14, allowing relative sliding between the cable 14 and the through hole in the threaded slider 11 without jamming, thus preventing interference from the threaded slider 11 on the contraction and stretching of the cable 14. Further, the guide ring 15 has a channel hole at its center that matches the outer diameter of the cable 14. Furthermore, the edges of the channel hole are rounded to avoid excessive wear on the outer surface of the cable 14, thus reducing its service life. The guide ring 15 prevents the movement of the cable 14 from interfering with the rotation of the driven bevel gear 19. Additionally, a limiting ring is provided on the arc-shaped outer wall of the take-up roller 13 to prevent the cable 14 from moving excessively towards the driving bevel gear 17 during winding, thereby affecting the movement of both the driving and driven bevel gears 17 and 19. Simultaneously, a spiral spring 16 is sleeved on the arc-shaped outer wall of the take-up roller 13, ensuring that the take-up roller 13 is always subjected to [certain conditions]. The spiral spring 16 provides a stable transmission effect. Furthermore, the driven bevel gear 19 meshes with the driving bevel gear 17 to achieve transmission. When the driving bevel gear 17 rotates, it drives the driven bevel gear 19 to rotate, which in turn drives the adjusting screw 18 to rotate. This changes the position of the threaded slider 11 inside the sleeve 8, thereby changing the compression state of the protective spring 12. When the display screen body 5 faces the sleeve 8 included in a certain protective component, it compresses the connecting rod 7 at that point. At this time, the transmission plate 9 slides along the inner wall of the sleeve 8 towards the bottom end of the sleeve 8 to apply pressure to the protective spring. When compression occurs at point 12, the cable 14 will rotate due to the elastic force of the spiral spring 16, causing the take-up roller 13 to rotate. This, in turn, causes the drive bevel gear 17 to rotate, which, in conjunction with the driven bevel gear 19 and the adjusting screw 18, changes the position of the threaded slider 11 within the sleeve 8. This, in turn, changes the compression state of the protective spring 12 in this direction, ensuring that it maintains good elastic protection without excessive compression. Otherwise, the elastic potential energy may be converted into kinetic energy, affecting the speed at which the display screen body 5 returns to its original shape and reducing the safety of the display screen body 5.

[0035] In addition, in order to ensure that the protective component can always keep the support rod 4 in a vertical position, a tensioning component is provided on the upper surface of the base 1. The tensioning component includes a hinge rod 20. The bottom end of the hinge rod 20 is hinged to the upper surface of the base 1, and the bottom end of the elastic member 21 is fixedly connected to the top end of the hinge rod 20.

[0036] In an embodiment of the present invention, six sets of tensioning components are provided, and the six sets of tensioning components are arranged one-to-one with the six sets of protective components, so that each set of protective components can provide support and protective clamping effect for the support rod 4 in the vertical direction. In addition, another set of hinge rods 20 is fixedly connected to the top of the elastic member 21. Specifically, the top of the other set of hinge rods 20 is hinged to the bottom outer wall of the sleeve rod 8, so that it works with the elastic member 21 to exert a downward pulling force on the sleeve rod 8, so that when the pulling force is applied to the connecting rod 7 and the sliding sleeve 6, it can better support and protect the support rod 4.

[0037] In addition, to reduce excessive wear between the support rod 4 and the sliding sleeve 6 due to the supporting force of the protective component when tilting, a positioning ball 22 is provided inside the sliding sleeve 6. Specifically, a positioning cavity is formed on the arc-shaped inner surface of the through hole at the center of the sliding sleeve 6. The positioning cavity is adapted to the positioning ball 22, so that when the positioning ball 22 is placed in the positioning cavity, a small part of it can be exposed. During installation, the end face of the positioning ball 22 abuts against the arc-shaped outer wall of the support rod 4, thereby turning the sliding friction between the support rod 4 and the sliding sleeve 6 into rolling friction, effectively reducing the wear between the support rod 4 and the sliding sleeve 6, and improving the stability and service life of the device during use.

[0038] In this invention, during use, when the display screen body 5 faces the sleeve rod 8 included in a certain protective component, the connecting rod 7 at that location is compressed. At this time, the transmission plate 9 slides along the inner wall of the sleeve rod 8 towards the bottom end of the sleeve rod 8 to compress the protective spring 12. Meanwhile, the cable 14, due to the elastic force of the spiral spring 16, drives the take-up roller 13 to rotate, thereby driving the driving bevel gear 17 to start rotating. This, in conjunction with the driven bevel gear 19 and the adjusting screw 18, changes the position of the threaded slider 11 within the sleeve rod 8, thereby changing the compression state of the protective spring 12 in this direction. This ensures that the spring 12 maintains good elastic protection without excessive compression, which could lead to the conversion of elastic potential energy into kinetic energy, affecting the speed at which the display screen body 5 returns to its original state and reducing the speed of the display screen body 5's recovery. For safety reasons, and to ensure that the protective components always keep the support rod 4 in a vertically pressed state, a number of tensioning components corresponding to the number of protective components are provided. These components, together with the elastic element 21, exert a downward pulling force on the sleeve rod 8. When this pulling force is applied to the connecting rod 7 and the sliding sleeve 6, it can better support and protect the support rod 4, ensuring the stability of the display screen body 5. Finally, to reduce excessive wear between the support rod 4 and the sliding sleeve 6 due to the supporting force of the protective components when the support rod 4 tilts, a positioning ball 22 and a positioning cavity adapted to the positioning ball 22 are provided inside the sliding sleeve 6. This transforms the sliding friction between the support rod 4 and the sliding sleeve 6 into rolling friction, effectively reducing wear between the support rod 4 and the sliding sleeve 6, and improving the stability and service life of the device during use.

[0039] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
