Description

Technical Field

[0001] The present invention relates to a disassembly and assembly tool for a star-shaped handle screw, and in particular to a disassembly and assembly tool for a star-shaped handle screw of a squeegee of a floor scrubber. Background Art

[0002] A floor scrubber is a common cleaning tool for cleaning the floor. It has high cleaning efficiency and can greatly reduce the labor intensity of cleaning personnel, so the application of floor scrubbers is becoming more and more extensive. In particular, floor scrubbers are increasingly used in workshops.

[0003] In a floor scrubber, a squeegee is an effective device for removing sewage from the ground. The main function of the squeegee is to create a sealed space by contacting the ground, and use the rubber strip to scrape some of the sewage from the ground through the fan to recover it into the sewage tank of the floor scrubber. Usually, the squeegee and the floor scrubber frame can be connected by a star-shaped handle screw.

[0004] When using a floor scrubber in a workshop, in order to clean the dirt on the squeegee in time to ensure the good operation of the floor scrubber, it is usually stipulated that the squeegee needs to be disassembled for cleaning after each floor scrubbing. However, such disassembly usually requires manual rotation of the star handle screw. Especially due to the large number of floor scrubbers in the workshop, such manual rotation of the star handle screw has a very low operating efficiency.

[0005] Moreover, long-term operation will cause the star handle screws to rust, and the squeegee is easily hit due to its protruding position, causing the screw position to shift. Therefore, when the above situation occurs, the star handle screws are difficult to disassemble and install manually. Therefore, it is often necessary to use a hammer to hit the side of the star handle to disassemble and install the star handle screws. Utility Model Content

[0006] The purpose of the present disclosure is to provide a disassembly and assembly tool for a star-handle screw, in particular a disassembly and assembly tool for a star-handle screw of a squeegee of a floor scrubber, by which the disassembly and assembly efficiency of the star-handle screw can be improved while ensuring that the star-handle screw is intact, and the star-handle screw can be easily disassembled and assembled, thereby making it easier and more efficient to clean components using such star-handle screws, such as the squeegee of a floor scrubber.

[0007] Therefore, the present disclosure provides a disassembly and assembly tool for a star-handle screw, wherein the star-shaped handle of the star-handle screw has two opposite grooves, and is characterized in that the disassembly and assembly tool comprises: a rotating base, the rotating base having a geometric center line; a clamping portion, the clamping portion having a first fixed rod and a second fixed rod, the first fixed rod and the second fixed rod are fixedly connected to one side of the rotating base and are arranged symmetrically about the geometric center line of the rotating base; and a rotating portion, the rotating portion is fixedly connected to the other side of the rotating base and is thus arranged opposite to the clamping portion, and the rotating portion includes a rotating handle.

[0008] With the disassembly tool according to the present disclosure, since each fixing rod of the clamping part can be clamped to two opposite grooves of the star handle of the star handle screw, the star handle screw is rotated by rotating the rotating base and thus each fixing rod by using the rotating handle of the rotating part. Therefore, with the disassembly tool according to the present disclosure, the star handle screw can be rotated not only from a distance but also with a small force, so the efficiency of disassembling and assembling the star handle screw can be improved and the star handle screw can be easily disassembled and assembled.

[0009] In some embodiments, the rotating base is configured as a rectangular plate, thereby making it possible to simply implement the rotating base.

[0010] In some embodiments, the first fixing rod and the second fixing rod extend from the rotating base at an increasing distance from the geometric center line of the rotating base. Thus, the spacing between the first fixing rod and the second fixing rod can be changed, so that the disassembly tool according to the present disclosure can be adapted to star-shaped handle screws of different sizes.

[0011] In some embodiments, the maximum distance between the first fixing rod and the second fixing rod is greater than the distance between the two opposite grooves of the star-shaped handle, and the minimum distance between the first fixing rod and the second fixing rod is less than the distance between the two opposite grooves of the star-shaped handle, thereby ensuring the adaptability of the disassembly and assembly tool according to the present disclosure.

[0012] In some embodiments, the first fixing rod and the second fixing rod have a circular cross section, thereby not only being able to simply realize the first fixing rod and the second fixing rod, but also being able to adapt to various shapes of grooves of the star-shaped handle screw.

[0013] In some embodiments, the rotating part includes a force-enhancing rotating rod as the rotating handle and a connecting rod connecting the force-enhancing rotating rod to the rotating base. Thus, not only can a small force be applied to rotate the star-shaped handle screw, but the operator can also disassemble and assemble the star-shaped handle screw from a longer distance, especially while standing, so that the operator's operation is more convenient.

[0014] In some embodiments, the star-shaped handle screw is configured to mount the squeegee of the floor scrubber on the floor scrubber frame. Therefore, the disassembly and assembly tool according to the present disclosure can be particularly used for disassembling the star-shaped handle screw of the squeegee of the floor scrubber.

[0018] The following description sets forth specific details to facilitate a full understanding of the present disclosure. However, the present disclosure can be implemented in a variety of other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present disclosure. Therefore, the present disclosure is not limited to the specific embodiments disclosed below.

[0021] As mentioned above, directly rotating the star handle of the star handle screw by hand to disassemble the star handle screw has a very low operating efficiency. In addition, if the star handle screw is rusted and / or the position of the star handle screw is shifted, a greater force is required to disassemble the star handle screw, making it difficult to disassemble the star handle screw.

[0022] In view of this, the present disclosure is dedicated to providing a disassembly tool that can quickly disassemble and assemble a star-handle screw while ensuring that the star-handle of the star-handle screw is intact. Since the star-handle 20 of the star-handle screw has at least two opposite grooves 21, 22 (see Figure 2 ), therefore, the disassembly and assembly tool according to the present invention utilizes two fixing rods to effectively fix the star-shaped handle and can easily realize the rapid disassembly and assembly of the star-shaped handle screw by rotating the force-enhancing rotating rod.

[0023] For the convenience of description, a disassembly and assembly tool 10 for a star-shaped handle screw according to an embodiment of the present disclosure is taken as an example for description below.

[0024] Reference Figure 1 and Figure 2 , which respectively show a stereoscopic view of a disassembly tool 10 for a star-shaped handle screw according to an embodiment of the present disclosure and a cross-sectional view of the disassembly tool 10 when rotating the star-shaped handle screw. The disassembly tool 10 can be particularly used for a star-shaped handle 20 having two opposite grooves. However, it is also conceivable that the disassembly tool 10 can also be used for handles of any other shape having two opposite grooves.

[0025] The disassembly tool 10 according to the present disclosure may include a rotating base 100 , a clamping portion 200 , and a rotating portion 300 .

[0026] The rotating base 100 may have a geometric centerline.

[0027] The clamping part 200 may have a first fixing rod 210 and a second fixing rod 220. The first fixing rod 210 and the second fixing rod 220 may be fixedly connected to one side of the rotating base 100 and arranged symmetrically about a geometric center line of the rotating base 100.

[0028] The rotating portion 300 may be fixedly connected to the other side of the rotating base 100 and thus be arranged opposite to the clamping portion 200. The rotating portion may include a rotating handle.

[0029] Since the first fixing rod 210 and the second fixing rod 220 of the clamping part 200 can be clamped to the two opposite grooves 21 and 22 of the star handle 20 of the star handle screw, the star handle screw is rotated by rotating the rotating base 100 and thus rotating the first fixing rod 210 and the second fixing rod 220 using the rotating handle of the rotating part 300. The disassembly tool disclosed in the present invention can not only rotate the star handle screw remotely but also with less force, so the efficiency of disassembling the star handle screw can be improved and the star handle screw can be easily disassembled.

[0030] According to some embodiments of the present disclosure, the rotating base 100 may be configured as a flat rectangular plate having a certain thickness, so that the rotating base 100 may be simply implemented.

[0031] According to some embodiments of the present disclosure, the first fixing rod 210 and the second fixing rod 220 may extend from the rotating base 100 at an increasingly greater distance relative to the center line of the geometric shape of the rotating base 100. Therefore, the farther the first fixing rod 210 and the second fixing rod 220 are from the rotating base 100, the greater the spacing between the first fixing rod 210 and the second fixing rod 220.

[0032] Star handle screws of different sizes can be adapted by changing the spacing between the first fixing rod 210 and the second fixing rod 220. When the spacing between the two opposite grooves 21, 22 of the star handle 20 of the star handle screw is large, the first fixing rod 210 and the second fixing rod 220 can be shallowly inserted into the two opposite grooves 21, 22 of the star handle 20. When the spacing between the two opposite grooves 21, 22 of the star handle 20 of the star handle screw is small, the first fixing rod 210 and the second fixing rod 220 can be deeply inserted into the two opposite grooves 21, 22 of the star handle 20.

[0033] In this regard, it is advantageous that the maximum distance between the first fixing rod 210 and the second fixing rod 220 can be greater than the distance between the two opposite grooves 21 and 22 of the star handle 20, and the minimum distance between the first fixing rod 210 and the second fixing rod 220 can be less than the distance between the two opposite grooves 21 and 22 of the star handle 20. In this way, the adaptability of the disassembly and assembly tool according to the present disclosure can be ensured.

[0034] According to some embodiments of the present disclosure, the first fixing rod 210 and the second fixing rod 220 may have a circular cross section, thereby not only being able to simply implement the first fixing rod 210 and the second fixing rod 220, but also being able to adapt to various shapes of grooves of the star-shaped handle screw.

[0035] According to some embodiments of the present disclosure, the rotating part 300 may include a force-enhancing rotary rod 310 as the rotating handle and a connecting rod 320 connecting the force-enhancing rotary rod 310 with the rotating base 100. Thus, the star-shaped handle screw can be rotated by applying only a small force through the force-enhancing rotary rod 310. In addition, through the connecting rod 320, the operator can disassemble and assemble the star-shaped handle screw from a longer distance, especially while standing, so that the operator's operation is more convenient.

[0036] According to some embodiments of the present disclosure, the star-shaped handle screw may be configured to install the squeegee of a floor scrubber on the frame of the floor scrubber. In other words, the disassembly and assembly tool according to the present disclosure may be particularly used for disassembling the star-shaped handle screw of the squeegee of the floor scrubber.

[0037] In summary, according to the present disclosure, a disassembly and assembly tool is realized, which can not only quickly disassemble and assemble the star-shaped handle screw, but also has a simple structure, is easy to use and has a low manufacturing cost. In addition, the disassembly and assembly tool according to the present disclosure can be used for star-shaped handle screws with star-shaped handles, and can also be used for screws with handles of any other shape including two opposite grooves.

[0038] The features disclosed in this application document may be important and may be implemented for the implementation of the embodiments in different design solutions not only individually but also in any combination. The present disclosure is not limited to the embodiments shown, but includes or extends to all technical equivalents that may fall within the effective scope of the attached claims.
