Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment, and in particular to a portable dust removal device. Background Technology

[0002] Liquid crystal displays (LCDs) are a type of flat panel display used in televisions and computers. Their advantages include low power consumption, small size, and low radiation. LCDs utilize a liquid crystal solution in two polarizing materials. When an electric current passes through the liquid, the crystals rearrange to achieve image formation. However, over time, dust accumulates on the surface of LCDs, causing the screen to become dim and the display quality to deteriorate. Therefore, a dust removal device is needed to wipe away the dust.

[0003] In the process of developing this application, the inventors discovered the following problems with the prior art:

[0004] In existing technologies, the display screen is usually cleaned by attaching a sponge or cleaning cloth to one end of a long rod. However, in existing technologies, the long rod and the base for mounting the sponge or cleaning cloth are usually fixed by screws. This design takes up a lot of space during transportation and storage, making it inconvenient to carry. Furthermore, it is inconvenient to clean and replace the sponge or cleaning cloth when it gets dirty.

[0005] Therefore, those skilled in the art have provided a portable dust removal device to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a portable dust removal device that enables quick disassembly, cleaning, and replacement of sponges, and reduces the overall size of the device during storage and transport, making it more convenient to carry and store.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A portable dust removal device includes a connecting plate, with hinge plates hinged to both sides of the upper surface of the connecting plate. A fixing member is embedded at the center of the upper surface of each of the two hinge plates. A locking mechanism is provided at the center of the front and rear end faces of the outer walls of each of the two fixing members. Each of the four locking mechanisms includes a fixing box. An insert is slidably disposed inside each of the four fixing boxes. A U-shaped rod is fixedly disposed on the front end face of each of the four inserts. A second spring is movably sleeved at both ends of the outer wall of each of the four U-shaped rods. A sliding rod is fixedly disposed at the center of the lower end of both sides of the inner wall of each of the two hinge plates.

[0009] Both sliding rods are movably sleeved with a No. 1 spring on their outer walls. A main rod is fixedly installed at the center of the lower end face of the connecting plate. External threaded tubes are fixedly sleeved at both ends of the outer wall of the main rod. A support mechanism is provided on the outer wall of the main rod. The support mechanism includes a sliding sleeve. Internal threaded tubes are rotatably installed at both ends of the outer wall of the sliding sleeve. Pull rods are hinged to both sides of the center of the outer wall of the sliding sleeve. A slider is hinged to one end of each of the two pull rods.

[0010] Furthermore, the sliding sleeve is slidably sleeved on the outer wall of the main body rod, and the two internally threaded tubes are respectively threadedly sleeved on the outer walls of the two externally threaded tubes.

[0011] Furthermore, the two sliders are respectively slidably sleeved on the outer walls of the two slide rods, and the two ends of the first springs are respectively fixedly connected to one side of the two sliders and one side of the inner wall of the two hinge plates.

[0012] Furthermore, both ends of the plurality of the second springs are respectively fixedly connected to the front end faces of the four inserts and the front end faces of the inner walls of the four fixing boxes.

[0013] Furthermore, slots are provided at the upper center of the front and rear end faces of the outer walls of the two hinge plates, and the four inserts are respectively embedded in the four slots.

[0014] Furthermore, grooves are provided at both ends of the lower end of the two fixing members, and the upper ends of the two hinge plates are respectively embedded in the four grooves.

[0015] Furthermore, the four fixing boxes are respectively fixedly installed at the center of the front and rear end faces of the outer wall of the two fixing members, and a sponge is fixedly installed at the center of the upper end face of each of the two fixing members.

[0016] This utility model has the following beneficial effects:

[0017] 1. The portable dust removal device proposed in this utility model can be rotated to disengage the lower end of the internal threaded tube from the lower end of the external threaded tube. Then, the sliding sleeve can be pulled upward to adjust the rotation angle of the two pull rods, thereby pushing the two hinge plates to flip and close. At this time, rotating the upper end of the internal threaded tube allows it to be threaded onto the outer wall of the upper end of the external threaded tube, thereby fixing the position of the sliding sleeve. This reduces the overall footprint of the device, making it easier to store and improving its portability.

[0018] 2. The portable dust removal device proposed in this utility model allows two U-shaped rods located at the front and rear ends of the same fixing component to be pulled forward and backward respectively. This causes two inserts to slide within two fixing boxes, allowing the two inserts to disengage from the two slots and compress four No. 2 springs. At this point, the fixing component can be pulled upward to remove it for cleaning and replacement of the sponge. After cleaning, the fixing component is re-embedded into the hinge plate, and the two U-shaped rods are released so that the two inserts are embedded into the two slots under the action of the No. 2 springs, fixing the position of the fixing component. This enables quick disassembly and replacement of the fixing component, facilitating the cleaning of the sponge. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1 to 4 One embodiment provided by this utility model:

[0027] A portable dust removal device includes a connecting plate 1. Hinged plates 4 are hinged to both sides of the upper surface of the connecting plate 1. Fixing members 3 are embedded in the center of the upper end of each of the two hinged plates 4. Locking mechanisms 8 are provided at the center of the front and rear ends of the outer walls of the two fixing members 3. Each of the four locking mechanisms 8 includes a fixing box 803. Inserts 804 are slidably arranged inside each of the four fixing boxes 803. U-shaped rods 801 are fixedly arranged on the front end of each of the four inserts 804. Second springs 802 are movably sleeved at both ends of the outer walls of the four U-shaped rods 801. Sliding rods 9 are fixedly arranged at the center of the lower ends of both sides of the inner walls of the two hinged plates 4.

[0028] Two sliding rods 9 are movably sleeved with a spring 10 on their outer walls. A main rod 6 is fixedly installed at the center of the lower end face of the connecting plate 1. External threaded tubes 5 are fixedly sleeved at both the upper and lower ends of the outer wall of the main rod 6. A support mechanism 7 is installed on the outer wall of the main rod 6. The support mechanism 7 includes a sliding sleeve 703. Internal threaded tubes 702 are rotatably installed at both the upper and lower ends of the outer wall of the sliding sleeve 703. Pull rods 701 are hinged on both sides of the center of the outer wall of the sliding sleeve 703. A slider 704 is hinged at one end of each of the two pull rods 701.

[0029] Specifically, the hinge plate 4 connects the fixing part 3, thereby changing the rotation angle of the hinge plate 4 through the support mechanism 7. This allows the fixing part 3 and the sponge 2 to be flipped and stored, reducing the footprint of the device and making it easier to carry and store. The locking mechanism 8 allows the hinge plate 4 and the fixing part 3 to be assembled, enabling quick disassembly of the fixing part 3 during use. By simplifying the disassembly and fixing of the sponge 2, it can be quickly removed for cleaning and replacement.

[0030] Reference Figure 1 , Figure 2 The sliding sleeve 703 is slidably sleeved on the outer wall of the main rod 6, and the two internally threaded tubes 702 are respectively threadedly sleeved on the outer walls of the two externally threaded tubes 5.

[0031] Specifically, by threading the internally threaded tube 702 onto the outer wall of the externally threaded tube 5, the position of the sliding sleeve 703 can be fixed.

[0032] Reference Figure 3 Two sliders 704 are respectively slidably sleeved on the outer walls of two slide rods 9, and the two ends of two No. 1 springs 10 are respectively fixedly connected to one side of the two sliders 704 and one side of the inner wall of the two hinge plates 4.

[0033] Specifically, when a single hinge plate 4 is subjected to force at one end near the connecting plate 1, the hinge plate 4 on the force-bearing side can rotate under force, so that the slider 704 slides along the slide rod 9 toward the first spring 10 and squeezes the first spring 10 while the position of the sliding sleeve 703 remains unchanged. At this time, the support angle of the force-bearing pull rod 701 can be changed, and then the two sponge wipers 2 with different angles can be used to clean and wipe the parts of the display screen surface and the display screen frame that are difficult to keep wiped in balance.

[0034] Reference Figure 4 Multiple No. 2 springs 802 are fixedly connected at both ends to the front ends of four inserts 804 and the front ends of the inner walls of four fixed boxes 803, respectively.

[0035] Specifically, when the U-shaped rod 801 is pulled to move the insert 804, the insert 804 will compress the second spring 802. When the U-shaped rod 801 is released, the elastic force of the second spring 802 can reset the insert 804.

[0036] Reference Figure 3 The two hinge plates 4 have slots 11 through the upper center of the front and rear ends of the outer wall, and four inserts 804 are respectively embedded in the four slots 11.

[0037] Specifically, the insert 804 is embedded inside the groove 11 to connect and fix the fastener 3 and the hinge plate 4.

[0038] Reference Figures 1 to 3 The two fasteners 3 have grooves at both ends of their lower front and rear sides, and the two hinge plates 4 are respectively embedded in the four grooves at both ends of their upper front and rear sides.

[0039] Specifically, by embedding the front and rear sides of the upper surface of the hinge plate 4 into the two grooves at the lower end of the fixing member 3, the position of the fixing member 3 can be initially fixed.

[0040] Reference Figure 1 , Figure 2 Four fixing boxes 803 are respectively fixedly installed at the center of the front and rear end faces of the outer wall of the two fixing parts 3, and a sponge 2 is fixedly installed at the center of the upper end face of the two fixing parts 3.

[0041] Specifically, the display screen can be cleaned by using two sponges 2, and the sponges 2 and the fixing parts 3 can be quickly disassembled by the locking mechanism 8.

[0042] Working principle: During cleaning, the hinge plate 4 on one side is subjected to force, causing it to rotate. This allows the slider 704 to slide along the slide rod 9 towards the first spring 10, compressing it, while the sliding sleeve 703 remains in place. This changes the support angle of the pull rod 701 on the force-bearing side. Two sponge wipes 2 with different angles can simultaneously wipe the sides of the display screen and the side bezels where the screen is difficult to balance. When the two hinge plates 4 are back on the same plane, the first spring 10 at the lower end of the hinge plate 4, which was flipped by the force, pushes the slider 704 back to its original position, thus resetting the pull rod 701 on that side. The cleaning process is complete. Pulling the U-shaped rod 801 causes the insert 804 to disengage from the groove 11. At this point, the fixing part 3 can be pulled upwards to remove it, making it easy to clean and replace the sponge 2 fixed on its upper surface. Then, rotate the lower internal thread tube 702 to disengage it from the lower external thread tube 5. At this point, the rotation angle of the two pull rods 701 can be changed by moving the sliding sleeve 703 upwards, which can then push the two hinge plates 4 to rotate and close. Then, rotate the upper internal thread tube 702 so that its threads are engaged with the outer wall of the upper external thread tube 5, thereby achieving the effect of fixing the position of the sliding sleeve 703. This reduces the footprint of the device, making it easier to carry and store.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
