Description

Technical Field

[0001] This utility model relates to the field of structural component fixing technology, specifically a quick fixing structure between structural components. Background Technology

[0002] In the fields of machining and structural design, the fixing structure between structural components is the most fundamental design element, and its quality directly affects the performance of the entire mechanical part. Traditional fixing structures between structural components mainly rely on welding, bolting, and riveting. While these structures perform well in terms of structural strength and stability, they still have certain limitations in terms of assembly and disassembly speed and flexibility. This is especially true when fixing large structural components, as there are many installation and disassembly points, resulting in poor flexibility and an inability to meet the needs of rapid assembly and disassembly. Summary of the Invention

[0003] To address the problems of numerous installation and disassembly points and poor flexibility in traditional fixing structures between structural components, this invention provides a new quick fixing structure between structural components.

[0004] This utility model is achieved using the following technical solution:

[0005] A quick-fixing structure between structural components includes an upper structural component, a lower structural component, a front component, and two rear components. The upper structural component is positioned above the lower structural component. The upper structural component has a front notch at the center of its bottom surface that mates with the front component. The bottom surface of the front component has two front threaded holes distributed laterally and arranged vertically. The front end of the lower structural component has two front through holes that mate with the two front threaded holes, and each of the two front through holes and the two front threaded holes is fitted with two front bolts. The rear end of the bottom surface of the upper structural component has two rear notches, each with horizontally arranged intermediate pressure blocks at both ends. The top surface of the lower structural component... The rear end is provided with two fixing grooves, and the top surface of the lower structural component is also provided with two protrusions. The two protrusions are located in front of the two fixing grooves and in the middle of the two rear notches respectively. The rear side of the two protrusions is flush with the rear side of the corresponding intermediate pressure block. Both protrusions are provided with rear threaded holes. The lower ends of the two rear components are respectively slidably adapted to the two fixing grooves. The upper ends of the two rear components are provided with forward-extending extensions. The two extensions are respectively located in the corresponding rear notches and are pressed against the corresponding intermediate pressure block and protrusions. Both rear components are provided with rear through holes. The rear through holes and rear threaded holes are adapted to rear bolts.

[0006] Instructions for use: During installation, first fix the front component to the lower structural component using the two front bolts, then install the upper structural component so that the front notch of the upper structural component abuts against the front component. Next, slide the two rear components from back to front into the space formed by the corresponding rear notch and fixing groove. Finally, fix the lower structural component, upper structural component, and rear components with the two rear bolts to complete the installation of the upper and lower structural components. This method requires few installation points and is quick and convenient. For disassembly, simply loosen the two front bolts and two rear bolts, then slide the upper structural component forward to separate the upper and lower structural components; or directly remove the two rear bolts and then slide the upper structural component backward to separate the upper and lower structural components. This method requires few removal points and is quick and easy.

[0007] Furthermore, the two rear components are arranged symmetrically about the front component, resulting in better structural stability.

[0008] Furthermore, the bottom surface of the rear end of the front component is a front slope that is arranged obliquely upward from front to back, which reduces frictional loss between the front component and the front notch, and also facilitates installation and disassembly.

[0009] Furthermore, the bottom surfaces of both extensions are first inclined surfaces that slope upwards from back to front, and the top surfaces of the intermediate pressure blocks are second inclined surfaces that are adapted to the first inclined surfaces on the extensions, which reduces frictional loss between the extensions and the intermediate pressure blocks, and also facilitates installation and disassembly.

[0010] Furthermore, the cross-sections of the two protrusions are both semi-circular, and the tops of the two protrusions are higher than the middle pressure block. The bottom surfaces of the two extensions are respectively provided with arc-shaped grooves that are adapted to the two protrusions, thus making the structure more specific and standardized.

[0011] Furthermore, the rear end of the top surface of the lower structural member is provided with a guide bar arranged in the front-to-back direction, and the rear end of the bottom surface of the upper structural member is provided with a guide groove that matches the guide bar, so as to facilitate the positioning of the upper and lower structural members in the left-to-right direction during installation.

[0012] Furthermore, the bottom surface of the intermediate pressure block is flush with the bottom surface of the upper structural component, making the structure more specific and standardized.

[0013] Furthermore, both the front notch and the two rear notches are square notches, making the structure more specific and standardized.

[0014] Furthermore, both the front and rear through holes are countersunk through holes, and both the front and rear bolts are countersunk bolts, making the structure more specific and standardized.

[0015] The beneficial effects of this utility model are as follows: The quick-fixing structure described in this utility model achieves quick fixation between structural components by changing the structure of the upper and lower structural components and cooperating with the front and rear components. At the same time, the embedded design of the front and rear components enables quick assembly and disassembly between structural components. With fewer assembly and disassembly points and high flexibility, it provides a new approach for quick fixation between structural components in the fields of machining and structural design.

[0031] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0032] like Figures 1 to 9As shown, a quick-fixing structure between structural components includes an upper structural component 1, a lower structural component 2, a front component 3, and two rear components 4.

The rear end of the top surface of the lower structural component 2 has two rear notches 12. The lower structural member 2 is provided with two fixing grooves 22 and two protrusions 23 on the top surface. The two protrusions 23 are located in front of the two fixing grooves 22 and in the middle of the two rear notches 12.

Then slide the two rear components 4 from back to front into the space formed by the corresponding rear notch 12 and the fixing groove 22. Finally, fix the lower structural component 2, the upper structural component 1, and the rear components 4 using two rear bolts, thus completing the installation of the upper structural component 1 and the lower structural component 2. There are few installation points, making installation quick and convenient. During disassembly, simply loosen the two front bolts and the two rear bolts, and then slide the upper structural component 1 forward to separate the upper structural component 1 and the lower structural component 2; or directly remove the two rear bolts, and then slide the upper structural component 1 backward to separate the upper structural component 1 and the lower structural component 2, thus completing the removal of the upper structural component 1 and the lower structural component 2.

The bottom surface of the two extensions 41 is respectively provided with arc-shaped grooves 44 that are adapted to the two protrusions 23, thus making the structure specific and standardized.

[0038] In specific implementation, the rear end of the top surface of the lower structural member 2 is provided with a guide bar 25 arranged in the front-back direction, and the rear end of the bottom surface of the upper structural member 1 is provided with a guide groove 15 that matches the guide bar 25, so as to facilitate the positioning of the upper structural member 1 and the lower structural member 2 in the left-right direction during installation.

[0039] In this specific embodiment, the bottom surface of the intermediate pressure block 13 is flush with the bottom surface of the upper structural component 1, thus making the structure more specific and standardized.

[0040] In this specific embodiment, the front notch 11 and the two rear notches 12 are all square notches, which makes the structure more specific and standardized.
