Description

Technical Field

[0001] The invention relates to the technical field of motorcycles, and in particular to a tool for installing a plastic fastener of a motorcycle. Background Art

[0002] Nowadays, the connection between the two plastic parts of motorcycles is through the connection method of metal sheet fasteners. In the process of pressing the metal sheet into the plastic column, it is difficult to control the column on the plastic part without being broken or skewed with ordinary tools. There will be problems such as difficulty in pressing in and pressing into place, which will cause the two plastic parts to not fit well enough. After long-term use, they will become loose and make noises. The plastic column may even break due to poor pressing of the metal sheet. Summary of the invention

[0003] The object of the present invention is to provide a motorcycle plastic fastener installation tool which improves the reliability of pressing a metal sheet into a plastic column in view of the deficiencies in the prior art.

[0004] To achieve this object, the present invention adopts the following technical solutions:

[0005] A motorcycle plastic fastener installation tool comprises a handle, a working pressure tube, an extension spring and an ejector structure; the handle is connected to the working pressure tube, the working pressure tube is a hollow cylindrical structure with an open bottom, the ejector structure and the extension spring are arranged in the working pressure tube, one end of the extension spring abuts against the top of the inside of the working pressure tube, and the other end abuts against the ejector structure;

[0006] The ejector structure includes an ejector portion and a pressing portion, both of which are cylindrical structures, the outer diameter of the pressing portion is consistent with the inner diameter of the working pressure tube, one end of the pressing portion is against the extension spring, and the center of the other end of the pressing portion is connected to the ejector portion.

[0007] As a further explanation, when the extension spring is compressed to the shortest state, the end of the ejector needle portion is accommodated in the working pressure tube.

[0008] To further explain, a first partition is provided inside the working pressure tube, and the first partition divides the interior of the working pressure tube into a first accommodating chamber and a second accommodating chamber; the extension spring and the pressing portion are arranged in the first accommodating chamber; a hole is opened in the middle of the first partition, and when the extension spring is in a natural state, the ejector pin portion passes through the first partition and is exposed from the bottom of the working pressure tube.

[0009] As a further explanation, the bottom of the working pressure tube is a chamfered structure inclined inwards.

[0010] To further explain, the chamfered structure has an inclination angle of 45°.

[0011] As a further explanation, the handle and the working pressure tube are connected via threads.

[0012] The beneficial effects of the present invention are as follows: when in use, the handle is pressed, and the handle transmits force to the metal plate through the working pressure tube. At the same time, the ejector part of the ejector structure is inserted into the plastic column to play a positioning role. As the pressure is pressed down, the ejector structure shrinks into the working pressure tube, and the plastic column also enters the working pressure tube. At the same time, the bottom of the working pressure tube presses the metal plate to the bottom of the plastic column, fixing the first plastic part and the second plastic part together. When pulled out, the ejector structure is separated from the plastic column, and the extension spring pushes the ejector structure out and resets it, which is convenient for the next press-fit. Under the positioning effect of the ejector structure and the working pressure tube on the plastic column, it will not tilt during the downward pressing process. The ejector part extends into the plastic column, indirectly strengthening the strength of the plastic column, and maintaining sufficient strength when the metal plate is pressed into the plastic column so as not to tilt, so that the metal plate and the plastic column always remain in a vertical state until the metal plate is pressed into place.

[0013] The motorcycle plastic fastener installation tool of the present invention prevents the plastic column from breaking and deforming, improves the reliability of plastic part connection, avoids updating the structure, and thus reduces the cost of modifying the mold.

DETAILED DESCRIPTION

[0020] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0021] like Figure 1-Figure 4As shown, a motorcycle plastic fastener installation tool comprises a handle 1, a working pressure tube 2, an extension spring 3 and an ejector structure 4; the handle 1 is connected to the working pressure tube 2, the working pressure tube 2 is a hollow cylindrical structure with an open bottom, the ejector structure 4 and the extension spring 3 are arranged in the working pressure tube 2, one end of the extension spring 3 abuts against the top of the inside of the working pressure tube 2, and the other end abuts against the ejector structure 4;

[0022] The ejector structure 4 includes an ejector portion 42 and a pressing portion 41. Both the pressing portion 41 and the ejector portion 42 are cylindrical structures. The outer diameter of the pressing portion 41 is consistent with the inner diameter of the working pressure tube 2. One end of the pressing portion 41 is against the extension spring 3, and the center of the other end of the pressing portion 41 is connected to the ejector portion 42.

[0023] The first plastic part 01 is provided with a perforation, and the second plastic part 02 is provided with a hollow plastic column 021. The first plastic part 01 is arranged at the top, and the second plastic part 02 is arranged at the bottom. The plastic column 021 of the second plastic part 02 passes through the perforation of the first plastic part 01. When using, the handle 1 is pressed, and the handle 1 transmits the force to the metal plate 03 through the working pressure tube 2. At the same time, the ejector part 42 of the ejector structure 4 is inserted into the plastic column 021 to play a positioning role. With the downward pressure, the ejector structure 4 shrinks into the working pressure tube 2, and the plastic column 021 also enters the working pressure tube 2. At the same time, the bottom of the working pressure tube 2 presses the metal plate 03 to the bottom of the plastic column 021, fixing the first plastic part 01 and the second plastic part 02 together. When pulling out, the ejector structure 4 is separated from the plastic column 021, and the extension spring 3 ejects the ejector structure 4 and resets it, which is convenient for the next press-fitting. Under the positioning effect of the ejector structure 4 and the working pressure tube 2 on the plastic column 021, the plastic column 021 will not tilt during the pressing process. The ejector part 42 extends into the plastic column 021, indirectly strengthening the strength of the plastic column 021, and maintaining sufficient strength when the metal plate 03 is pressed into the plastic column 021 so as not to tilt, so that the metal plate 03 and the plastic column 021 always remain in a vertical state until the metal plate 03 is pressed into place.

[0024] The motorcycle plastic fastener installation tool of the present invention prevents the plastic column 021 from breaking and deforming, improves the reliability of plastic part connection, avoids updating the structure, and thus reduces the cost of modifying the mold.

[0025] To further explain, when the extension spring 3 is compressed to the shortest state, the end of the ejector needle portion 42 is received in the working pressure tube 2 .

[0026] During the process from the insertion of the ejector pin 42 into the plastic column 021 to the completion of the pressing and fixing of the metal plate 03, the ejector pin 42 is always inserted into the plastic column 021. At the same time, the working pressure tube 2 can completely press the metal plate 03 to the bottom of the plastic column 021, reducing the gap between the metal plate 03 and the first plastic part 01, thereby achieving a better fixing effect.

[0027] Further explanation, a first partition plate 21 is provided inside the working pressure tube 2, and the first partition plate 21 divides the inside of the working pressure tube 2 into a first accommodating chamber 201 and a second accommodating chamber 202; the extension spring 3 and the pressing portion 41 are arranged in the first accommodating chamber 201; a hole is opened in the middle of the first partition plate 21, and when the extension spring 3 is in a natural state, the ejector pin portion 42 passes through the first partition plate 21 and is exposed from the bottom of the working pressure tube 2.

[0028] When the extension spring 3 is continuously compressed, the ejector structure 4 retracts into the working pressure tube 2. When the pressing portion 41 hits the first partition 21, the first partition 21 serves as the stop end, preventing the ejector structure 4 from continuing to shrink. At this time, the force of the working pressure tube 2 directly acts on the metal plate 03. This design can prevent the extension spring 3 from being over-compressed and causing the extension spring 3 to lose its elastic deformation restoring force. When the extension spring 3 is in a natural state, the ejector portion 42 passes through the first partition 21 and emerges from the bottom of the working pressure tube 2, making it convenient to align the ejector portion 42 with the plastic column 021.

[0029] For further explanation, the bottom of the working pressure tube 2 is a chamfered structure 22 inclined inwards.

[0030] When the metal plate 03 is pressed down with force, the inwardly inclined chamfered structure 22 causes the outer edge of the metal plate 03 to protrude upward, so that the metal plate 03 is deformed inward when pressed into the plastic column 021, so as to reduce scratches on the plastic column 021.

[0031] To further explain, the chamfered structure 22 has an inclination angle of 45°.

[0032] The inclination angle of 45° makes it easier to deform the metal plate 03 and press the first plastic part 01 and the second plastic part 02 .

[0033] To further explain, the handle 1 and the working pressure tube 2 are connected via threads.

[0034] The handle 1 and the working pressure tube 2 can be produced separately and then assembled, which is convenient for production and manufacturing.

[0035] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The content of this specification should not be understood as limiting the present invention.
