Description

Technical Field

[0001] The present application relates to the technical field of screw fixing structures, and specifically discloses a screw kit for fixing inclined parts. Background Art

[0002] In the assembly of industrial parts, the fixed connection between various parts is involved, including bolt connection, screw connection, etc. For screw connection, when it is necessary to fix the inclined plate on another horizontally placed part, such as the attached Figure 4 As shown, a screw commonly used in the prior art is used, and the bottom of the screw head is a plane. When the board is tilted, it is affected by the demoulding direction, and the screw hole on the horizontal part must be in a vertical direction. This causes the screw to be unable to be locked perpendicular to the board direction, resulting in point contact between the screw head and the board. The fixing effect is poor and the screw pressure is concentrated on one point on the board, resulting in increased pressure on the board, which can easily damage the board.

[0003] Therefore, in view of this, the inventor provides a screw kit for fixing a tilted part to solve the above-mentioned problem. Utility Model Content

[0004] The utility model aims to solve the problem that in the connection between the traditional horizontally placed parts and the inclined plate, when the screw connection mode is adopted, point contact is formed between the screw pan head and the inclined plate, which easily damages the plate.

[0005] In order to achieve the above-mentioned purpose, the basic scheme of the utility model provides a screw kit for fixing inclined parts, including a screw pan head and a screw shaft fixed to the bottom end of the screw pan head, an elastic ring is sleeved on the screw shaft below the screw pan head, and the outer diameter of the elastic ring is smaller than the outer diameter of the screw pan head.

[0006] Furthermore, the outer diameter of the screw pan head gradually increases along the connection between the screw pan head and the screw shaft toward the top end surface of the screw pan head.

[0007] Furthermore, the top end of the screw pan head is provided with an annular abutment that can abut against the elastic ring.

[0008] Furthermore, the bottom end surface of the annular abutment is a plane.

[0009] Furthermore, the screw shaft comprises an equal-diameter section fixedly connected to the screw pan head and a tapered section fixedly connected to the end of the equal-diameter section.

[0010] Furthermore, the elastic ring is specifically a rubber ring.

[0011] The principle and effect of this scheme are:

[0012] 1. Compared with the prior art, the present invention increases the contact area between the plate and the horizontally placed parts and the plate by adding an elastic ring, and the elastic ring is fixed between the plate and the screw head by directly inserting the screw into the screw hole of the part.

[0013] 2. Compared with the prior art, the utility model adjusts the position of the rubber ring to maintain surface contact when fixing the inclined board, and decomposes the vertical locking force into forces perpendicular to the board and in another direction through the rubber ring, thereby protecting the board and strengthening the fixing effect of the board, solving the problem that in the connection between the traditional horizontally placed parts and the inclined board, point contact is formed between the screw pan head and the inclined board when the screw connection method is used, which easily damages the board.

[0019] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0020] The reference numerals in the drawings of the specification include: part 1, screw hole 2, screw pan head 3, rubber ring 4, plate 5, annular abutment 6, equal diameter section 7, conical section 8, existing screw pan head 9.

[0021] A screw kit for fixing a tilted part, the embodiment of the invention is as follows Figure 1 and Figure 2 As shown:

[0022] The screw head comprises a screw pan head 3, a screw shaft integrally formed at the bottom end of the screw pan head 3, and an elastic ferrule sleeved on the screw shaft below the screw pan head 3. In this embodiment, the elastic ferrule is specifically a rubber ferrule 4.

[0023] The outer diameter of the screw pan head 3 gradually increases along the connection between the screw pan head 3 and the screw shaft toward the top end surface of the screw pan head 3 , and the outer diameter of the rubber ring 4 is smaller than the outer diameter of the top end of the screw pan head 3 .

[0024] An annular abutment platform 6 which can abut against the rubber ring 4 is integrally formed on the top of the screw pan head 3 , and the bottom end surface of the annular abutment platform 6 is a plane.

[0025] The screw shaft includes an equal-diameter section 7 integrally formed at the bottom of the screw pan head 3 and a tapered section 8 integrally formed at the end of the equal-diameter section 7. The tapered section 8 is inserted into the screw hole 2 of the part 1, and the screw is clamped by the equal-diameter section 7. The equal-diameter section 7 also serves to reserve a position for the rubber ring 4.

[0026] When the plate 5 is placed horizontally on the horizontally placed part 1, the rubber ring 4 is first put on the screw rod, and then the screw is inserted into the screw hole 2. The bottom of the rubber ring 4 contacts the plate 5, and the rubber ring 4 is under pressure and is located in the middle of the screw.

[0027] Example 2 Figure 3 As shown, when the plate 5 is tilted and placed on the horizontally placed part 1, the rubber ring 4 is first put on the screw rod, and then the screw is inserted into the screw hole 2. The bottom of the rubber ring 4 contacts the plate 5 and has a tilting tendency. When the screw pan head 3 continues to squeeze the rubber ring 4 downward, the inclined surface of the screw pan head 3 will squeeze the rubber ring 4 to deflect it. The inclined surface of the screw pan head 3 is supported by the deformation of the rubber ring 4 to keep it vertical. At the same time, the rubber ring 4 can also be used to squeeze the plate 5 to fix it on the part 1, ensuring that the plate is not damaged.

[0028] When installing boards with different inclinations, although the inclination of each board is different, it can be adjusted by the position of the rubber ring 4 to maintain surface contact. The rubber ring 4 decomposes the vertical locking force into forces perpendicular to the board and in another direction, which protects the board while strengthening the fixing effect of the board, replacing the current point contact between the existing screw pan head 9 and the board in the prior art.

[0029] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
