Description

Technical Field

[0001] This utility model relates to the field of precision sheet metal parts technology, specifically a precision sheet metal part. Background Technology

[0002] Sheet metal processing is a comprehensive cold working process for thin metal sheets, including shearing, punching, cutting, compound cutting, bending, welding, riveting, splicing, and forming. Its most significant characteristic is that the thickness of the same part is consistent. Products processed through sheet metal processing are called sheet metal parts. The term "sheet metal part" generally varies across different industries and is often used in assembly contexts.

[0003] Existing sheet metal enclosures cannot be quickly and accurately connected and positioned, making sheet metal installation inconvenient and unable to provide effective drop protection. In the event of a fall, the protection of internal parts of the precision sheet metal enclosure will be compromised. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1-5As shown, this utility model provides a technical solution: a precision sheet metal part, including a housing 1, with limiting platforms 101 set at the four corners inside the housing 1, a connecting plate 4 fixedly connected to the outer side of the limiting platform 101, positioning plates 401 fixedly connected to both ends of the connecting plate 4, a limiting plate 403 fixedly connected to one end of the top of the positioning plate 401, and a mounting hole 402 opened at the other end of the top of the positioning plate 401, a positioning block 5 installed inside the mounting hole 402, and a spring 501 fixedly connected to the rear end of the positioning block 5. The rear end of the spring 501 is fixedly connected to the mounting block 502. An inner box plate 1 2 is movably installed between the positioning plate 401 and the limiting plate 403. Several shock-absorbing bosses 202 are provided in the middle of the inner box plate 1 2. Positioning grooves 201 are opened on the left and right sides of the rear end of the inner box plate 1 2. An inner box plate 2 3 is movably installed between the positioning plate 401 and the limiting plate 403. Several shock-absorbing bosses 302 are provided in the middle of the inner box plate 2 3. Positioning grooves 301 are opened on the left and right sides of the rear end of the inner box plate 2 3.

[0022] Furthermore, positioning groove 1 201, positioning groove 2 301, and positioning block 5 are all semi-circular structures with the same diameter.

[0023] The above technical solution facilitates quick installation and fixation of inner panel 1 2 and inner panel 2 3 by using positioning blocks 5 installed in positioning slots 1 201 and 2 301.

[0024] Furthermore, both the shock-absorbing boss 1 202 and the shock-absorbing boss 2 302 are semi-circular bosses with the same radius, and the radius is the distance from the bottom of the positioning plate 401 to the top of the limiting plate 403.

[0025] Through the above technical solution, both the shock-absorbing boss 202 and the shock-absorbing boss 302 can contact the inner wall of the housing 1 to dampen the vibrations experienced by the housing 1.

[0026] Furthermore, the connecting plate 4, the positioning plate 401, and the limiting plate 403 are formed by bending the same sheet metal.

[0027] The above technical solution enables the connecting plate 4, positioning plate 401 and limiting plate 403 to form an integrated structure, which facilitates the improvement of sheet metal production efficiency.

[0028] Furthermore, the connecting plate 4 is fixedly installed on the limiting platform 101 at the four corners of the box 1 by welding.

[0029] The above technical solution integrates the housing 1, connecting plate 4, inner box panel 1 2, and inner box panel 2 3 into a whole, ensuring that the connecting plate 4, inner box panel 1 2, and inner box panel 2 3 will not fall off during use.

[0030] Working principle: First, insert the inner box panel 2 slowly between the positioning plate 401 and the limiting plate 403. Due to the spring 501 at the rear end of the positioning block 5, the positioning block 5 will be squeezed into the mounting hole 402 when it contacts the inner box panel 2, which will not hinder the movement of the inner box panel 2. After the inner box panel 2 contacts the bottom of the inner side of the box 1, move the inner box panel 2 left and right so that the positioning groove 201 reaches the position of the positioning block 5. The spring 501 will pop the positioning block 5 out of the mounting hole 402 and into the positioning groove 201 to fix the inner box panel 2. Then, fix the inner box panel 3 through the above steps. The two inner box panels 2 and the two inner box panels 3 form a protective structure inside the box 1.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
