Abstract
Description
Technical Field
[0001] This utility model relates to the field of support base technology, and in particular to an improved support base. Background Technology
[0002] As a structural component, the main function of a support base is to provide a stable support surface for bearing and fixing heavy objects or other structures. In various application scenarios, such as machinery, buildings, furniture, and display racks, support bases play a crucial role. Their design needs to comprehensively consider multiple aspects such as load-bearing capacity, stability, adaptability, durability, and aesthetics. In practical applications, the specific form and material selection of support bases will vary depending on the usage scenario and requirements.
[0003] Most existing support bases have relatively simple structures and poor shock absorption. This may result in heavy objects not being able to be stably placed on the support base in swaying environments (such as construction sites or earthquake sites). In other words, in swaying environments, the support base may not be able to effectively absorb and disperse the energy generated by earthquakes or mechanical vibrations, causing heavy objects to sway or even fall. Falling heavy objects may injure nearby people, damage equipment, or damage building structures, leading to serious safety accidents. Moreover, in construction sites, the falling of heavy objects caused by swaying will greatly reduce work efficiency (because extra time and effort are needed to reposition and secure the heavy objects). In addition, long-term swaying and vibration may damage the structure of the support base itself, thus greatly reducing the service life of the support base and making it impractical. Utility Model Content
[0004] The purpose of this invention is to solve the problem that existing support bases are mostly simple in structure and have poor shock absorption, which makes it impossible to place heavy objects stably in a shaking environment. Therefore, an improved support base is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An improved support base includes a cover plate, an upper fixing frame, and a lower fixing frame. The cover plate is provided with four sets of first nuts, and the cover plate is detachably mounted on the top of the upper fixing frame via the four sets of first nuts. The upper fixing frame is located above the lower fixing frame, and the lower fixing frame is provided with four sets of second nuts. The base also includes:
[0007] A connecting buffer mechanism is provided, which is located at the middle position on the opposite side of the upper fixed frame and the lower fixed frame, and is used to connect the upper fixed frame and the lower fixed frame and to buffer the shaking of the upper fixed frame.
[0008] Eight sets of pressure-resistant plates are fixedly installed on opposite sides of the upper and lower fixed frames in a symmetrical four-by-four configuration. The four sets of pressure-resistant plates on the upper fixed frame and the four sets of pressure-resistant plates on the lower fixed frame are equipped with a rolling mechanism, which enables the upper fixed frame to achieve stable displacement.
[0009] A spring stabilizing mechanism is provided on the upper and lower fixed frames to enable the upper fixed frame to maintain balance and stability when subjected to external forces.
[0010] Preferably, the connecting buffer mechanism includes two sets of mounting plates, which are respectively installed at the middle position on opposite sides of the upper fixed frame and the lower fixed frame, and a main spring is connected to both sets of mounting plates, with the main spring located between the two sets of mounting plates.
[0011] Preferably, the rolling mechanism includes four sets of upper arc discs and four sets of lower arc discs. The four sets of upper arc discs are respectively fixedly installed on the bottom ends of four sets of pressure-resistant plates on the upper fixed frame, and the four sets of lower arc discs are respectively fixedly installed on the top ends of four sets of pressure-resistant plates on the lower fixed frame. A set of pressure-resistant balls is placed between each of the four sets of upper arc discs and the four sets of lower arc discs, and the outer wall of the pressure-resistant balls is in contact with the inner wall of the upper arc discs and the lower arc discs, respectively.
[0012] Preferably, each of the four sets of lower arc disks is equipped with a soft spring at its top, and the four sets of lower arc disks are connected to the four sets of upper arc disks respectively through the soft springs, with the pressure-resistant ball located inside the soft spring.
[0013] Preferably, the spring stabilizing mechanism includes four sets of grooves and four sets of through slots. The four sets of grooves are formed at the top of the lower fixed frame and are located between every two sets of lower arc discs. The four sets of through slots are formed through the bottom of the upper fixed frame and are located between every two sets of upper arc discs. The positions of the four sets of grooves and the four sets of through slots correspond to each other. Lower fixing blocks are installed on the two opposite sidewalls of the four sets of grooves, and upper fixing blocks are installed on the two opposite sidewalls of the four sets of through slots. A first spring and a second spring are fixedly connected to the two sets of lower fixing blocks in each set of grooves, and the two sets of lower fixing blocks in each set of grooves are connected to the two sets of upper fixing blocks in each set of through slots through the first spring and the second spring, respectively.
[0014] Preferably, the first spring and the second spring are arranged alternately.
[0015] Compared with the prior art, the advantages of this utility model are:
[0016] 1. This utility model, through the setting of the rolling mechanism on the anti-pressure plate, enables the anti-pressure ball to move between the upper and lower arc plates when the environment in which the support base is located shakes (at which time a heavy object has been placed on the cover plate). Since the lower fixed frame is fixed, the upper fixed frame will produce a displacement opposite to the direction of shaking relative to the lower fixed frame, consuming the energy of shaking, thereby reducing the shaking of the upper fixed frame, thus ensuring the stability of the heavy object placed on the cover plate (i.e., achieving stable placement of the heavy object), effectively preventing the heavy object on the cover plate from falling off. Furthermore, through the setting of the soft spring between the upper and lower arc plates, a portion of the energy of the shaking of the upper fixed frame can be absorbed and consumed, thereby further reducing the shaking of the upper fixed frame and improving the stability of the entire support base.
[0017] 2. By incorporating a buffer mechanism, this utility model utilizes a main spring to absorb and disperse the instantaneous impact force when a heavy object is placed on the cover plate and the pressure-resistant ball is subjected to the impact force from the heavy object. This prevents the pressure-resistant ball from being damaged due to sudden high pressure, thereby protecting the structural integrity of the entire support base and extending its service life. Furthermore, the flexible connection of the main spring allows the support base to better absorb and disperse vibration energy when facing external vibrations, thus improving the overall shock resistance and stability of the support base. In addition, when the ground vibrates, the reaction force generated by the deformation of the main spring can dissipate the energy of the ground shaking, allowing the heavy object to stabilize more quickly, further improving the stability of the entire support base.
[0018] 3. This utility model, through the setting of the spring stabilizing mechanism, can form a stable connection between the upper and lower fixed frames by using the interlaced first and second springs. This connection can evenly distribute the external force on the upper fixed frame in any direction, thereby providing a stable and consistent buffering effect. This helps to maintain the balance and stability of the upper fixed frame, reducing its tilting or twisting caused by uneven force. Furthermore, if the first spring is subjected to a compressive force, the adjacent second spring will be subjected to a tensile force. The elastic forces generated by them can cancel out part of the torque, making the upper fixed frame more stable when subjected to force and less prone to rotation or tilting. This is more conducive to maintaining the stability of the upper fixed frame, and further improves the stability of the entire support base. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0025] Reference Figures 1 to 4 An improved support base includes a cover plate 1, an upper fixing frame 3, and a lower fixing frame 4. The cover plate 1 is provided with four sets of first nuts 2, and the cover plate 1 is detachably mounted on the top of the upper fixing frame 3 via the four sets of first nuts 2. The upper fixing frame 3 is located above the lower fixing frame 4. The lower fixing frame 4 is provided with four sets of second nuts 5, which allow the lower fixing frame 4 to be mounted on the ground. A connecting buffer mechanism is provided at the middle position of the opposite side of the upper fixing frame 3 and the lower fixing frame 4 to connect the upper fixing frame 3 and the lower fixing frame 4 and to buffer the shaking of the upper fixing frame 3. The connecting buffer mechanism includes two sets of mounting plates 11, which are respectively installed at the middle position of the opposite side of the upper fixing frame 3 and the lower fixing frame 4. A main spring 12 is connected to both sets of mounting plates 11, and the main spring 12 is located between the two sets of mounting plates 11. Four sets of pressure-resistant plates 10 are installed on opposite sides. The four sets of pressure-resistant plates 10 on the upper fixed frame 3 and the four sets of pressure-resistant plates 10 on the lower fixed frame 4 are equipped with a rolling mechanism to enable the upper fixed frame 3 to achieve stable displacement. The rolling mechanism includes four sets of upper arc discs 13 and four sets of lower arc discs 14. The four sets of upper arc discs 13 are respectively fixedly installed at the bottom of the four sets of pressure-resistant plates 10 on the upper fixed frame 3, and the four sets of lower arc discs 14 are respectively fixedly installed at the top of the four sets of pressure-resistant plates 10 on the lower fixed frame 4. A set of pressure-resistant balls 15 is placed between the four sets of upper arc discs 13 and the four sets of lower arc discs 14. The outer wall of the pressure-resistant balls 15 is in contact with the inner wall of the upper arc discs 13 and the lower arc discs 14, respectively. The top of each of the four sets of lower arc discs 14 is equipped with a soft spring 16, and the four sets of lower arc discs 14 are connected to the four sets of upper arc discs 13 through the soft springs 16. The pressure-resistant balls 15 are located inside the soft springs 16.
[0026] When the environment in which the support base is located shakes (at which time a heavy object has been placed on top of the cover plate 1), the anti-pressure ball 15 will move between the upper arc plate 13 and the lower arc plate 14 under the action of inertia. Since the lower fixed frame 4 is fixed, the upper fixed frame 3 will have a displacement opposite to the direction of shaking relative to the lower fixed frame 4, which consumes the energy of shaking and reduces the shaking of the upper fixed frame 3. This ensures the stability of the heavy object placed on the cover plate 1 and effectively prevents the heavy object on the cover plate 1 from falling. The soft spring 16 between the upper arc plate 13 and the lower arc plate 14 mainly serves to consume the energy of shaking. When the anti-pressure ball 15 moves between the upper arc plate 13 and the lower arc plate 14, the soft spring 16 will deform, thereby absorbing and consuming some of the energy of shaking. This energy consumption mechanism helps to further reduce the shaking of the upper fixed frame 3, thereby improving the stability of the entire support base.
[0027] The central main spring 12 enables a flexible connection between the upper fixed frame 3 and the lower fixed frame 4. This flexible connection firstly provides a certain buffering and support function. When a heavy object is placed on the cover plate 1, the pressure-resistant ball 15 will be subjected to impact force. The main spring 12 can absorb and disperse this instantaneous impact force, preventing the pressure-resistant ball 15 from being damaged due to sudden large pressure, thereby protecting the structural integrity of the entire support base and extending its service life. Secondly, through the flexible connection of the main spring 12, the support base can better absorb and disperse vibration energy when facing external vibrations, thereby improving the overall shock resistance and stability of the entire support base. Finally, when the ground vibrates (i.e., the surrounding environment shakes), the main spring 12 will deform, thereby generating a reaction force. This reaction force can effectively consume the energy of the ground shaking, allowing the heavy object to stabilize more quickly, thereby further improving the stability of the entire support base.
[0028] Reference Figures 2 to 4A spring stabilizing mechanism is provided on both the upper fixed frame 3 and the lower fixed frame 4 to ensure that the upper fixed frame 3 can maintain balance and stability when subjected to external force. The spring stabilizing mechanism includes four sets of grooves and four sets of through slots. The four sets of grooves are opened at the top of the lower fixed frame 4 and are located between every two sets of lower arc disks 14. The four sets of through slots are provided through the bottom of the upper fixed frame 3 and are located between every two sets of upper arc disks 13. The positions of the four sets of grooves and the four sets of through slots correspond to each other. Lower fixing blocks 9 are installed on the two opposite side walls of the four sets of grooves, and upper fixing blocks 8 are installed on the two opposite side walls of the four sets of through slots. A first spring 6 and a second spring 7 are fixedly connected to the two sets of lower fixing blocks 9 in each set of grooves, and the two sets of lower fixing blocks 9 in each set of grooves are connected to the two sets of upper fixing blocks 8 in each set of through slots through the first spring 6 and the second spring 7, respectively. The first spring 6 and the second spring 7 are staggered.
[0029] Since each set of first springs 6 and second springs 7 are installed in a staggered manner within the support base, and both ends of the first springs 6 and second springs 7 are connected to the upper fixing block 8 on the upper fixing frame 3 and the lower fixing block 9 on the lower fixing frame 4 respectively, they can distribute the external force relatively evenly regardless of the direction of the force applied to the upper fixing frame 3. This provides a stable and consistent buffering effect, helps maintain the balance and stability of the upper fixing frame 3, and reduces tilting or twisting caused by uneven force. Furthermore, if the first spring 6 is subjected to a compressive force, the adjacent second spring 7 will be subjected to a tensile force. The elastic forces generated by them can cancel out some of the torque, making the upper fixing frame 3 more stable when subjected to force and less prone to rotation or tilting. This design allows the support base to maintain good stability and reliability when subjected to various external forces, thereby further improving the overall stability of the support base.
[0030] In this utility model, the lower fixing frame 4 is fixed to the ground by the second nut 5, and the cover plate 1 is fixed together with the upper fixing frame 3 by the first nut 2. There are four pressure-resistant plates 10 in the middle of the upper fixing frame 3 and the lower fixing frame 4. The upper and lower pressure-resistant plates 10 are respectively provided with an upper arc plate 13 and a lower arc plate 14 in the middle. The pressure-resistant ball 15 and the soft spring 16 are sandwiched in the middle of the upper arc plate 13 and the lower arc plate 14.
[0031] When a heavy object is placed on top of the cover plate 1, and the environment in which the support base is located shakes, the anti-pressure ball 15 will move between the upper arc plate 13 and the lower arc plate 14 due to inertia. Since the lower fixed frame 4 is fixed, the upper fixed frame 3 will have a displacement opposite to the direction of shaking relative to the lower fixed frame 4, consuming the energy of shaking and thus reducing the shaking of the upper fixed frame 3. This ensures the stability of the heavy object placed on the cover plate 1 and effectively prevents the heavy object from falling off the cover plate 1. The soft spring 16 between the upper arc plate 13 and the lower arc plate 14 mainly serves to consume the energy of the shaking of the upper fixed frame 3. When the anti-pressure ball 15 moves between the upper arc plate 13 and the lower arc plate 14, the soft spring 16 will deform, thereby absorbing and consuming some of the shaking energy. This energy consumption mechanism helps to further reduce the shaking of the upper fixed frame 3, thereby improving the stability of the entire support base.
[0032] The central main spring 12 enables a flexible connection between the upper fixed frame 3 and the lower fixed frame 4. This flexible connection firstly provides a certain buffering and support function. When a heavy object is placed on the cover plate 1, the pressure-resistant ball 15 will be subjected to impact force. The main spring 12 can absorb and disperse this instantaneous impact force, preventing the pressure-resistant ball 15 from being damaged due to sudden large pressure, thereby protecting the structural integrity of the entire support base and extending its service life. Secondly, through the flexible connection of the main spring 12, the support base can better absorb and disperse vibration energy when facing external vibrations, thereby improving the overall shock resistance and stability of the entire support base. Finally, when the ground vibrates (i.e., the surrounding environment shakes), the main spring 12 will deform, thereby generating a reaction force. This reaction force can effectively consume the energy of the ground shaking, allowing the heavy object to stabilize more quickly, thereby further improving the stability of the entire support base.
[0033] Since each set of first springs 6 and second springs 7 are installed in a staggered manner within the support base, and both ends of the first springs 6 and second springs 7 are connected to the upper fixing block 8 on the upper fixing frame 3 and the lower fixing block 9 on the lower fixing frame 4 respectively, they can distribute the external force relatively evenly regardless of the direction of the force applied to the upper fixing frame 3. This provides a stable and consistent buffering effect, helps maintain the balance and stability of the upper fixing frame 3, and reduces tilting or twisting caused by uneven force. Furthermore, if the first spring 6 is subjected to a compressive force, the adjacent second spring 7 will be subjected to a tensile force. The elastic forces generated by them can cancel out some of the torque, making the upper fixing frame 3 more stable when subjected to force and less prone to rotation or tilting. This design allows the support base to maintain good stability and reliability when subjected to various external forces, thereby further improving the overall stability of the support base.
[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
