Description

Technical Field

[0001] This utility model relates to the field of support structure technology, specifically to an elastic base. Background Technology

[0002] refer to Figure 1 As shown, an existing elastic base includes a horizontally mounted mounting plate with four independent elastic support members fixed at the four corners of its lower side. When the mounting plate bears a supported object or is subjected to downward pressure, the four elastic support members simultaneously undergo compressive deformation, converting the pressure into elastic potential energy, thereby achieving a buffering and shock-absorbing effect and preventing the supported equipment from directly bearing rigid impacts.

[0003] However, the existing elastic bases still have the following problems in actual use: Because the elastic deformation capacity of the elastic support has an inherent limit, the maximum pressure it can withstand is limited by material properties and structural strength. When the downward pressure on the mounting plate exceeds the ultimate bearing capacity of the elastic support, the deformation of the elastic support will exceed its elastic recovery range, easily leading to irreversible deformation or even breakage. This damage not only causes the elastic buffering function of the base to fail, but may also cause the mounting plate to tilt due to inconsistent deformation of the support, thereby reducing the stability of the supported equipment and even causing equipment damage or safety hazards.

Detailed Implementation

[0026] 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.

[0027] For reference as follows Figures 1-4 The present invention will be described as follows: Example: The elastic base of this application forms a support structure that combines support stability and overload protection through the structural design of multiple components such as the base body 1, mounting plate 2, fasteners, elastic support bars 8, and cover 14.

[0028] An elastic base includes a base body 1 made of plastic. The base body 1 has a rectangular structure with a square cross-section. The square cross-section design provides a uniform installation reference for the circumferentially arranged elastic support bars 8, ensuring that the force of each support point is balanced.

[0029] The base 1 has through holes 3 running through its upper and lower sides. The through holes 3 are assembly interfaces that mate with the upper and lower end fixing parts. The inner diameter of the through holes 3 is precisely matched with the outer diameter of the threaded tube 4 in the fixing parts, ensuring the coaxiality and connection stability after the threaded tube 4 is inserted, and providing a structural basis for the adjustment function of the subsequent mounting plate 2 and support bolts 7.

[0030] The upper side of the base 1 is provided with a mounting plate 2, which is the direct carrier for equipment installation. The mounting plate 2 is a plate structure and has mounting holes 13, which enable fixed connection with the supported equipment.

[0031] The upper and lower ends of the base 1 are respectively connected to fasteners, which are made of metal.

[0032] The fastener includes a screw tube 4, with an annular fixing plate 5 connected to the edge of one end of the screw tube 4. The screw tube 4 is adapted to be inserted into the through hole 3. The fixing plate 5 is fixedly connected to the base 1 by screws. The fixing plate 5 is provided with a connecting hole 9, and the upper and lower end faces of the base 1 are respectively provided with fixing holes 10 corresponding to the connecting hole 9.

[0033] The fastener is connected to the base 1 by screws via a fixing plate 5. The connecting hole 1 on the fixing plate 5 is precisely aligned with the fixing hole 1 on the base 1 to ensure the rigidity of the connection between the fastener and the base 1. The threaded tube 4 is inserted into the through hole of the base 1 to form radial positioning and prevent the fastener from shifting under stress. This design, in which "metal components bear the core stress and plastic base 1 provides basic support," leverages the advantages of different materials while reducing overall manufacturing costs, thus conforming to the economic principles of engineering design.

[0034] Considering the limitations of the plastic base 1 in terms of threaded connection and load-bearing strength, metal fasteners are set at the upper and lower ends of the base 1. These fasteners serve as connection hubs and simultaneously realize three major functions: "structural reinforcement, thread adaptation, and position adjustment".

[0035] The fastener adopts an integrated structure of "screw tube 4 + fixing plate 5", both made of metal materials (such as ordinary carbon steel or stainless steel) and have sufficient strength and thread load-bearing capacity. Among them, the screw tube 4 is a cylindrical tubular structure with internal threads machined on the inner wall, serving as the connection carrier for subsequent studs 6 or support bolts 7; the fixing plate 5 is a ring structure, welded to one end edge of the screw tube 4 or integrally formed, and its function is to achieve a fixed connection with the base 1 through screws, transferring the force of the metal fastener to the base 1.

[0036] The mounting plate 2 has a stud 6 on its lower side that is threaded to the screw tube 4 located on the upper side. This design gives the mounting plate 2 the ability to be adjusted vertically, allowing for precise adjustment according to the installation height requirements of the equipment and enhancing the flexibility of the base.

[0037] The stud 6 fixed to the lower side of the mounting plate 2 forms a threaded pair with the threaded tube 4 of the fixing member on the upper side of the base 1. Since the threaded tube 4 is rigidly connected to the base 1 through the fixing plate 5, rotating the mounting plate 2 will cause the stud 6 to move up and down along the axis of the threaded tube 4, thereby changing the height of the mounting plate 2 relative to the base 1. The mounting hole 13 provided on the mounting plate 2 is used to fix it to the supported equipment. After the height of the mounting plate 2 is adjusted, its position can be kept stable by the self-locking characteristic of the thread.

[0038] The lower screw tube 4 is internally threaded with a support bolt 7. By rotating the support bolt 7, the protrusion height of its lower end can be precisely adjusted, thereby changing the position of the lowest support point of the entire base.

[0039] It also includes elongated elastic support bars 8, which are made of bent steel plates. The upper end of the elastic support bar 8 is fixedly connected to the side of the base 1 (by screws), and there are four elastic support bars 8 arranged at intervals around the circumference of the base 1. In the working state, the elastic support bar 8 mainly absorbs the pressure transmitted by the mounting plate 2 through its own bending deformation.

[0040] The cross-section of the base 1 is square, and elastic support bars 8 are connected to the four sides of the base 1.

[0041] The upper end of the elastic support bar 8 is provided with a second connection hole 11, and the side of the base body 1 is provided with a second fixing hole 12 corresponding to the second connection hole 11.

[0042] When the base is subjected to normal pressure, the elastic support bar 8 bends outward under pressure. At this time, the extension length of the pre-set support bolt 7 ensures that its lower end maintains a gap with the support surface, allowing the elastic support bar 8 to freely perform its buffering function. When the pressure on the mounting plate 2 exceeds the elastic limit of the elastic support bar 8 (i.e., the critical pressure at which the steel plate material is about to undergo plastic deformation), the bending amplitude of the elastic support bar 8 reaches its maximum value, and its lower end will contact the lower end face of the support bolt 7 to form a rigid support. At this time, the subsequent increase in pressure will be mainly borne by the rigid structure composed of the support bolt 7, the screw tube 4, and the base 1. The stress on the elastic support bar 8 is limited within the elastic recovery range, thereby avoiding irreversible plastic deformation or fracture damage due to overload.

[0043] It also includes a downward-opening cover 14, which is a rectangular structure. The cover 14 covers the upper end of the base 1, and the upper end of the elastic support bar 8 is located inside the cover 14. The inner and outer sides of the upper end of the elastic support bar 8 are respectively attached to the base 1 and the cover 14. This attached structure forms a radial constraint on the upper end of the elastic support bar 8, limiting the lateral displacement of the upper end of the elastic support bar 8 during bending deformation, ensuring that the deformation of the four elastic support bars 8 remains synchronized, avoiding uneven force due to the displacement of a single support bar, and thus ensuring the horizontal state of the mounting plate 2.

[0044] The upper side wall of the cover 14 is provided with a through hole 15 for the stud 6 to pass through. A spring 16 is sleeved on the stud 6. The upper end of the spring 16 abuts against the cover 14, and the lower end of the spring 16 abuts against the fixing plate 5. The spring 16 will apply an upward elastic force to the cover 14, so that the upper side of the cover 14 abuts against the lower side of the mounting plate 2.

[0045] The upper end of the spring 16, which is sleeved on the stud 6, abuts against the upper side wall of the cover 14, and the lower end abuts against the fixing plate 5 of the upper fixing member. In its natural state, the spring 16 is in a pre-compressed state, and the upward elastic force it generates continuously acts on the cover 14, ensuring that the upper side of the cover 14 is always in close contact with the lower side of the mounting plate 2, forming surface contact. This contact method differs from traditional point contact or line contact support structures, effectively dispersing the pressure transmitted by the mounting plate 2.

[0046] When the supported equipment experiences instantaneous loads or vibrations, the force on the mounting plate 2 can be evenly transmitted to the spring 16 and the underlying seat 1 structure through the contact surface of the cover 14, preventing deformation of the mounting plate 2 caused by localized stress concentration. The surface contact cooperation of the cover 14 in limiting the upper end of the elastic support bar 8 effectively suppresses the horizontal swaying of the mounting plate 2, ensuring that the supported equipment remains in a stable installation state. In addition, the elastic force of the spring 16 can compensate for the assembly gap between the mounting plate 2 and the cover 14, further improving the tightness of the connection.

[0047] The side wall of the cover 14 is provided with deformation grooves 17 that run through its inner and outer sides and bottom. The number and position of the deformation grooves 17 correspond to the elastic support strips 8. When the elastic support strips 8 bend and deform, they may come into contact with and collide with the cover 14. The deformation grooves 17 allow the cover 14 to deform accordingly.

[0048] The lower end of the elastic support bar 8 is fitted with a rubber sleeve 18. The rubber sleeve 18 can act as a buffer when the support bar contacts the support surface, while preventing the metal support bar from directly rubbing against the ground and causing wear, thus reducing noise during use.

[0049] Based on the design and functional analysis of the above components, the technical advantages of this flexible base can be summarized in the following five points: 1. The adjustable support bolts 7 form a rigid protective limit for the elastic support bar 8. By controlling the sinking range of the base 1, the elastic support bar 8 is effectively prevented from being damaged due to excessive deformation. This solves the problem of fatigue failure of elastic components that is prone to occur in traditional elastic bases and extends the overall service life.

[0050] 2. The mounting plate 2 achieves height adjustment through the threaded connection between the stud 6 and the upper fixing part, and the support bolt 7 achieves support height adjustment through the threaded connection with the lower fixing part. The dual adjustment function enables the base to adapt to different equipment installation heights and site conditions, making it highly versatile.

[0051] 3. The plastic base 1 achieves lightweight and easy molding, the metal fasteners strengthen the threaded connection and load-bearing strength, the elastic steel plate support bar provides reliable elastic performance, and the rubber sleeve and spring 16 help to achieve buffering and noise reduction. The performance advantages of each material are fully utilized, while reducing manufacturing costs.

[0052] 4. The cover 14 completely covers the upper end of the elastic support bar 8 and the key parts of the fastener, effectively isolating dust and debris. At the same time, the deformation groove 17 adapts to the deformation of the support bar to avoid rigid collisions. The synergistic effect of the spring 16 and the cover 14 further enhances the stability of the mounting plate 2.

[0053] 5. Convenient and efficient assembly and maintenance: All components are connected by screws, making the assembly process simple and requiring no special tools; vulnerable parts such as elastic support bar 8 and spring 16 can be disassembled and replaced individually, reducing maintenance difficulty and cost.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
