[0001] This utility model relates to the field of integrated lower shell equipment, and more particularly to a lower shell with an integrated support structure. Background Technology
[0002] In the structural design of various electronic devices, mechanical equipment, or precision instruments, the lower shell is a key component for load-bearing and protection. Its structural rationality directly affects the stability, reliability, and assembly efficiency of the overall equipment. In current reciprocating compressors, the support structure of the shell assembly consists of four parts: the shell, the inner support pin, the support block, and the compression spring. The inner support pin is welded to the bottom of the shell, the support block is assembled with the inner support pin, the bottom end of the compression spring cooperates with the support block, and the top end of the compression spring supports the core part, playing a supporting and vibration damping role.
[0003] The above-mentioned device has the following defects: the supporting structure of the housing assembly consists of four parts: lower shell, inner support pin, support block, and compression spring. The large number of components increases the material cost of the product. Secondly, the assembly process is cumbersome, time-consuming and labor-intensive, increasing labor costs. Therefore, an integrated supporting structure lower shell is proposed to solve the above problems. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a lower shell with an integrated support structure, which aims to improve the problems of cumbersome assembly steps, time-consuming and labor-intensive processes, and increased manpower and material costs in the prior art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a lower shell with an integrated support structure, comprising a lower shell, a ring fixedly installed on the upper surface of the lower shell, a support assembly disposed inside the lower shell, an auxiliary assembly disposed at the bottom of the lower shell, a splicing interface formed on the left surface of the lower shell, a positioning groove formed on the left surface of the splicing interface, the auxiliary assembly comprising an auxiliary block, a positioning plate fixedly connected to the bottom of the auxiliary block, a positioning hole formed on the upper surface of the positioning plate, multiple sets of magnetic strips fixedly connected to the upper surface of the positioning plate, and multiple sets of anti-slip textures formed on the lower surface of the positioning plate.
[0006] As a further description of the above technical solution: the support assembly includes a support column, the outer wall of the support column is sleeved with a compression spring, and a positioning ring is fixedly installed on the top end of the compression spring.

[0012] This utility model has the following beneficial effects:
[0013] 1.

[0021] 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.
[0022] Reference Figure 1 - Figure 2 This utility model provides an embodiment of an integrated support structure lower shell, including a lower shell 1. The lower shell 1 serves as the basic load-bearing component of the overall structure, integrating functional modules such as a ring 2, a support component 3, an auxiliary component 4, and a splicing interface 5, providing rigid support and sealing protection. A ring 2 is fixedly installed on the upper surface of the lower shell 1, serving as a docking reference with the upper shell to ensure concentricity and sealing during assembly. The support component 3 is provided inside the lower shell 1, and the auxiliary component 4 is provided at the bottom of the lower shell 1. A splicing interface 5 is provided on the left surface of the lower shell 1, serving as an insertion channel with other shell modules to realize modular expansion functionality. A positioning groove 6 is provided on the left surface of the splicing interface 5, which ensures the uniqueness of the angle when adjacent shells are docked through geometric limiting, avoiding assembly misalignment.
[0023] Reference Figure 2 - Figure 4 The auxiliary component 4 includes an auxiliary block 41, which is fixedly installed on the lower surface of the lower housing 1. The top corner of the outer wall of the auxiliary block 41 is set with a rounded corner structure. The rounded corner structure of the auxiliary block 41 disperses stress concentration and avoids assembly damage. The bottom of the auxiliary block 41 is fixedly connected to a positioning plate 42, which is integrally formed with the auxiliary block 41 and serves as the bottom mounting reference surface to support the fixing requirements of the magnetic strip 44 and the anti-slip texture 45. The upper surface of the positioning plate 42 is provided with a positioning hole 43, which is used to insert bolts or pins to achieve precise positioning with external equipment. Multiple sets of magnetic strips 44 are fixedly connected to the upper surface of the positioning plate 42. The magnetic strips 44 achieve quick pre-fixation with the metal base through magnetic adsorption, simplifying the assembly process. Multiple sets of anti-slip textures 45 are provided on the lower surface of the positioning plate 42. The outer surface of the anti-slip textures 45 is set with an S-shaped structure. The anti-slip textures 45 are distributed in an S-shaped array on the lower surface of the positioning plate 42 to increase the friction coefficient and prevent horizontal slippage during equipment operation.
[0024] Reference Figure 2 - Figure 4The support assembly 3 includes a support column 31, which is vertically fixed to the lower surface of the inner wall of the lower housing 1. It serves as the guide shaft of the compression spring 32, transmitting axial load and limiting lateral displacement. The support column 31 is fixedly installed on the lower surface of the inner wall of the lower housing 1. The outer wall of the support column 31 is fitted with a compression spring 32. A positioning ring 33 is fixedly installed on the top of the compression spring 32. The positioning ring 33 is fixed to the top of the compression spring 32 and is used to connect with external components such as motor shafts or transmission components to achieve dynamic positioning and shock absorption. The top of the compression spring 32 is fixedly installed on the lower surface of the positioning ring 33. The bottom of the compression spring 32 is fixedly installed on the outer wall of the support column 31. The compression spring 32 is fitted on the outer wall of the support column 31 and absorbs impact vibration through elastic deformation, providing floating support force for the positioning ring 33.
[0025] Working principle:
[0026] The upper housing or external equipment first forms an annular contact surface with "ring 2". The outer diameter of ring 2 and the inner diameter of the upper housing adopt a transition fit to ensure concentricity. The lower end face of ring 2 is glued or screwed to the upper surface of the lower housing 1, making the lower housing 1 the final load-bearing body of the entire docking force, preventing stress concentration from causing sealing failure. External rotating parts, such as motor shafts, are inserted into the inner hole of "positioning ring 33". Positioning ring 33 restricts the radial swing of the rotating parts through its inner hole tolerance. When the rotating parts generate axial impact, the force is transmitted along positioning ring 33 to "compression spring 32". Compression spring 32 is sleeved on the outer wall of "support column 31". The lower end of support column 31 is rigidly connected to the lower surface of the inner wall of lower housing 1 to form a fixed fulcrum. Under the guidance of support column 31, compression spring 32 generates controllable compression to absorb energy. After the impact disappears, compression spring 32 returns to its original position, and positioning ring 33 drives the rotating parts back to the design height to achieve dynamic balance. The top of support column 31 is chamfered to prevent the compression spring 32 from jamming when it is over-compressed.
[0027] When the whole machine needs to be fixed to the metal base, the positioning plate 42 at the lower end of the auxiliary block 41 is used as the reference surface. The positioning plate 42 and the auxiliary block 41 are integrally formed to ensure verticality. The top corner of the outer wall of the auxiliary block 41 adopts a rounded corner structure to disperse the stress concentration caused by handling or impact and avoid micro-cracks. The magnetic strip 44 is pre-glued to the upper surface of the positioning plate 42 in multiple arrays, and generates instantaneous magnetic attraction with the metal base to achieve "pre-fixation". This facilitates one-handed operation of the bolts. After the pre-fixation is completed, the bolts are locked through the positioning hole 43 to form a rigid connection between the positioning plate 42 and the base. The inner wall of the positioning hole 43 can be provided with a countersunk platform to prevent the bolt head from protruding. The lower surface of the positioning plate 42 is processed with "anti-slip texture 45". Its S-shaped groove further increases the friction coefficient after the bolt is locked, suppressing the horizontal micro-slippage generated during the operation of the equipment.
[0028] When multiple machines need to be connected in parallel, the corresponding housing boss is inserted using the "interface 5". Interface 5 is a rectangular through slot that provides a insertion and removal channel. During the insertion process, the boss key on the adjacent housing cooperates with the "positioning groove 6". The geometric contour of the positioning groove 6 is a unique asymmetrical shape to ensure the uniqueness of the angle and avoid misalignment. After the insertion is completed, a continuous rigid chain is formed between the lower housings 1. The ring 2 and the support component 3 remain coaxial along the entire chain to achieve synchronous vibration reduction of multiple machines.
[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
