Description

Technical Field

[0001] This utility model relates to the field of double-sided erasing technology, and more specifically, to a magnetically adjustable double-sided eraser to prevent hand pinching. Background Technology

[0002] Magnetic glass cleaners are currently widely used for cleaning glass doors and windows. For glass doors and windows of different thicknesses, people either use glass cleaners with different magnetic attraction models, or glass cleaners with adjustable magnetic force. For example, the applicant previously disclosed patent number 201520921106.5, entitled "A Magnetic Glass Cleaner Adjustment Device". The reserved annular groove hole of this device is too short, which results in the magnetic force adjustment column rotating at too small an angle, affecting the number of steps on the stepped surface. If the number of steps is too small, the magnetic adjustment is not fine enough. If the number of steps is too large, the step length is too short, and it is easy to slip. Utility Model Content

[0003] To overcome the above deficiencies, this utility model provides a magnetic anti-pinch double-sided eraser that overcomes or at least partially solves the above technical problems.

[0004] This utility model provides a magnetically adjustable anti-pinch double-sided eraser, including a main eraser and a secondary eraser. The main eraser and the secondary eraser are magnetically attracted to each other. The main eraser includes an upper shell, an end plate and a magnet assembly. The upper shell is connected to the end plate and also includes a magnetic force adjustment drive gear. The magnetic force adjustment drive gear is connected to a handle on its side and is movably connected to the upper shell by a pin.

[0005] The upper shell has a hollow cavity structure. The upper surface of the upper shell has an inwardly recessed deep groove, and the lower end of the groove is connected to a central shaft. A magnetic adjustment column is fitted over the deep groove. The outer surface of the magnetic adjustment column is provided with a spiral groove. One side of the spiral groove is set as a step. The top of the magnetic adjustment column is provided with a gear, which meshes with the magnetic adjustment drive gear.

[0006] The magnet assembly is provided with a circular hole that matches the magnetic force adjustment column. A raised slider is provided on the inner wall of the circular hole. One side of the slider is configured as a second step corresponding to the step of the spiral groove. The magnet assembly is movably connected to the magnetic force adjustment column through the circular hole.

[0007] Preferably, the upper shell is further provided with two sliding pillars, which are respectively placed on both sides of the deep groove. The magnet assembly is provided with two sliding holes that match the sliding pillars. A cylinder is provided at the center of the inner wall of the end plate. Second fixing pillars that match the sliding pillars are provided on both sides of the cylinder. The sliding pillars pass through the sliding holes and are connected to the second fixing pillars.

[0008] Preferably, the magnetic adjustment column passes through the circular hole of the magnet assembly and is connected to the cylinder.

[0009] Preferably, a torsion spring is provided on the magnetic adjustment column, with one end of the torsion spring fixed on the magnetic adjustment column and the other end fixed on the central shaft.

[0010] Preferably, the non-stepped side of the spiral groove is configured as a smooth surface.

[0011] Preferably, the inner cavity of the magnet assembly is divided into four cavities by a partition, and the magnets are all placed in the cavities of the magnet assembly.

[0012] The present invention provides a magnetically adjustable, anti-pinch double-sided eraser, the beneficial effects of which include:

[0013] 1. When the magnet assembly is in the position of large or maximum magnetic attraction, reverse the upper shell so that the spiral groove of the magnetic force adjustment column faces upward. Under the action of gravity, the magnet assembly presses the spiral groove of the magnetic force adjustment column, forcing the magnetic force adjustment column to rotate, or under the action of the torsion spring, the magnetic force adjustment column rotates, or both work simultaneously. At this time, the magnetic force adjustment column rotates, thereby driving the gear to rotate to the position of minimum magnetic attraction, reducing the magnetic attraction between the main and auxiliary wipers of the glass cleaner to the minimum. This can effectively prevent the main and auxiliary wipers from being pinched by the large magnetic attraction when they are attracted to each other without gap, and it can also prevent the main and auxiliary wipers from being attracted by the large magnetic force and difficult to separate.

[0014] 2. During operation, attach the main and auxiliary cleaning tools to the glass to be cleaned. By turning the lever, the gear rotates in the direction of maximum magnetic attraction, which in turn drives the magnetic adjustment drive gear to rotate. The magnetic adjustment column rotates accordingly. At this time, the spiral groove of the magnetic adjustment column presses against the slider of the magnet assembly, causing the magnet assembly to move downwards. The entire magnet assembly moves downwards in the direction of maximum magnetic attraction until it reaches the appropriate magnetic attraction position. When the desired attraction is achieved, stop turning the lever. The second step rests on the step of the magnetic adjustment column, and the downward movement stops. Because both the gear and the magnetic adjustment drive gear are circular, this rotation angle is large, resulting in a larger rotation angle of the magnetic adjustment column. Consequently, the number of steps increases, and each step becomes longer and shorter, increasing the fineness of magnetic adjustment and making it less likely for the first and second steps to disengage.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Reference Figures 1-6 This utility model provides a technical solution: a magnetic anti-pinch double-sided wiper, including a main wiper and a secondary wiper, the main wiper and the secondary wiper are magnetically attracted to each other. The main wiper includes an upper shell 1, an end plate 2 and a magnet assembly 3. The upper shell 1 is connected to the end plate 2. It also includes a magnetic force adjustment drive gear 10. The magnetic force adjustment drive gear 10 is connected to a lever 11 on its side. The magnetic force adjustment drive gear 10 is movably connected to the upper shell 1 through a pin 9.

[0025] The upper shell 1 has a hollow cavity structure. The upper surface of the upper shell 1 is provided with an inwardly recessed deep groove 4. The lower end of the groove 4 is connected to a central shaft 24. The deep groove 4 is fitted with a magnetic adjustment column 5. The outer surface of the magnetic adjustment column 5 is provided with a spiral groove 6. One side of the spiral groove 6 is set as a step 7. The top of the magnetic adjustment column 5 is provided with a gear 8. The gear 8 meshes with the magnetic adjustment drive gear 10.

[0026] The magnet assembly 3 is provided with a circular hole 12 that matches the magnetic force adjustment column 5. A raised slider 13 is provided on the inner wall of the circular hole 12. One side of the slider 13 is configured as a second step 14 corresponding to the step 7 of the spiral groove 6. The magnet assembly 3 is movably connected to the magnetic force adjustment column 5 through the circular hole 12.

[0027] Furthermore, the upper shell 1 is provided with two sliding pillars 15, which are respectively placed on both sides of the deep groove 4. The magnet assembly 3 is provided with two sliding holes 16 that match the sliding pillars 15. The inner wall of the end plate 2 is provided with a cylinder 22 at its center. The cylinder 22 is provided with second fixing pillars 17 that match the sliding pillars 15 on both sides. The sliding pillars 15 pass through the sliding holes 16 and are connected to the second fixing pillars 17.

[0028] Furthermore, the magnetic adjustment column 5 passes through the circular hole 12 of the magnet assembly 3 and is connected to the cylinder 22.

[0029] Furthermore, a torsion spring 23 is provided on the magnetic adjustment column 5, with one end of the torsion spring 23 fixed on the magnetic adjustment column 5 and the other end fixed on the central shaft 24.

[0030] Furthermore, the non-stepped side of the spiral groove 6 is set as a smooth surface.

[0031] Furthermore, the inner cavity of the magnet assembly 3 is divided into four cavities 19 by the partition 18, and the magnets 21 are all placed in the cavities 20 of the magnet assembly 3.

[0032] Specifically, the working process or principle of this magnetic anti-pinch double-sided wiper is as follows: If the magnet assembly 3 is in a position with large or maximum magnetic attraction, the upper shell 1 is reversed so that the spiral groove 6 of the magnetic force adjustment column 5 faces upward. Under the action of gravity, the magnet assembly 3 presses the spiral groove 6, forcing the magnetic force adjustment column 5 to rotate, or under the action of the torsion spring 23, the magnetic force adjustment column 5 rotates, or both work simultaneously. At this time, the magnetic force adjustment column 5 rotates, thereby driving the gear 8 to rotate to the position with the minimum magnetic attraction, reducing the magnetic attraction between the main wiper and the auxiliary wiper to the minimum. This can effectively prevent the main and auxiliary wipers from pinching the hand due to the large magnetic attraction when they are attracted to each other without gap, and it can also prevent the main and auxiliary wipers from being attracted by large magnetic force and difficult to separate. During operation, the main and auxiliary wipers are attached to the glass to be cleaned. The lever 11 is used to rotate the gear towards the direction of maximum magnetic attraction, which in turn drives the magnetic adjustment gear. The magnetic adjustment column rotates accordingly. At this time, the slider 13 on the circular hole 12 of the magnet assembly 3 moves step by step along the spiral groove 6, causing the entire magnet assembly 3 to slide towards the direction of maximum magnetic attraction until it reaches the appropriate magnetic attraction position. Once the desired attraction is achieved, the lever 11 is stopped. When the main and auxiliary wipers are removed from the glass and the main wiper is flipped over, the magnet assembly 3, under the influence of gravity, presses against the spiral groove 6, forcing the magnetic adjustment column 5 to rotate, or under the torsion of the torsion spring 23, causes the magnetic adjustment column 5 to rotate, or both simultaneously. In this case, the magnetic adjustment column 5 rotates, thereby driving the gear 8 to rotate to the position of minimum magnetic attraction. Since both the gears and the magnetic adjustment drive gear are circular, the rotation angle is large, which in turn increases the rotation angle of the magnetic adjustment column, resulting in more steps and each step becoming longer and shorter. This increases the fineness of the magnetic adjustment and makes it less likely for the steps to slip off between each other.
