Description

Technical Field

[0001] This utility model relates to the field of base support frame technology, and in particular to an assembled base support frame. Background Technology

[0002] In the field of base support frame technology, traditional base support frames often rely on a single fixing structure or simple connectors when installing and fixing to the base.

[0003] During installation, these structures are prone to insecure fixing due to the lack of effective multi-coordination and stabilization mechanisms. This is especially true after external impact or long-term use, when the support frame and base are prone to loosening, affecting the overall stability of the structure. In addition, some support frames are not designed with ease of disassembly and assembly in mind, resulting in cumbersome and time-consuming operations when disassembly or replacement is required. The problem of unstable fixing during the installation of traditional support frames is particularly prominent, seriously affecting the safe operation and service life of the base and the upper equipment. Therefore, it is necessary to solve the above problems. 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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example: See Figure 1-6This utility model discloses an assembled base support frame, comprising a support frame 1 and two equidistant fixed platforms 2 fixed to the lower end of the support frame 1. The fixed platforms 2 facilitate the fixing of the support frame 1 and provide shear resistance to the support frame 1. A sliding cavity 14 with its lower end penetrating through the axis of the inner cavity of the fixed platform 2 is provided, through which a sliding block 6 is installed. A displacement cavity 7 is provided on the outer side of the sliding cavity 14, through which a T-shaped clamping piece 3 and a first spring 11 are installed. The displacement cavity 7 is located in the inner cavity of the fixed platform 2. Two main oil grooves 8 are provided in the support frame 1, each at the same end as the axis of the fixed platform 2, through which hydraulic oil is injected. An extrusion oil groove 9 is provided at the front end of the main oil groove 8, through which the hydraulic oil in the main oil groove 8 is used to squeeze the abutment block 4. A U-shaped opening is provided on the outer side of the top of the extrusion oil groove 9. The return oil groove 10 facilitates the return of hydraulic oil squeezed out of the oil groove 9 to the main oil groove 8; the other end of the return oil groove 10 is connected to the top of the main oil groove 8. Two T-shaped clamping pieces 3 adapted to their own curvature are installed on both sides of the fixed platform 2. The T-shaped clamping pieces 3 facilitate the effective fixation of the fixed platform 2, thereby stabilizing the support frame 1; and a sliding block 6 is slidably installed in the sliding cavity 14 opened in the inner cavity of the fixed platform 2. The sliding block 6 facilitates the compression of the T-shaped clamping pieces 3 to fix the T-shaped clamping pieces 3 to the base; the rear end of the T-shaped clamping piece 3 passes through the displacement cavity 7 and the side connecting the sliding cavity 14 so that the end of the T-shaped clamping piece 3 is located in the sliding cavity 14, and a first spring 11 is sleeved on the outer side of the rear end of the T-shaped clamping piece 3. The first spring 11 facilitates the provision of self-recovering driving force for the T-shaped clamping piece 3; the two ends of the first spring 11 abut against the two sides of the inner cavity of the displacement cavity 7.

[0022] In this invention, the upper end of the sliding block 6 is located inside the sliding cavity 14. The ends of the two T-shaped clamping pieces 3 abut against the upper sides of the sliding block 6, and a second spring 12 is sleeved on the outer side of the upper end of the sliding block 6. The second spring 12 facilitates the provision of driving force for the sliding block 6 to reset. The upper and lower ends of the second spring 12 abut against the top of the sliding cavity 14 and the upper ends of the T-shaped clamping pieces 3, respectively. A first one-way valve 13 with a driving structure is installed in the extrusion oil groove 9. The first one-way valve 13 facilitates the prevention of hydraulic oil in the extrusion oil groove 9 from flowing back to the main oil groove 8 directly through the first one-way valve 13. The one-way end of the first one-way valve 13 is connected to the main oil groove 8, which is connected to the extrusion oil groove 9. The inner cavity of the extrusion oil groove 9 is provided with an abutment groove 17, which facilitates the installation of the abutment block 4. A T-shaped abutment block is installed at the front end of the inner cavity of the extrusion oil groove 9. The connecting block 4 has its rear end penetrating the abutment groove 17, allowing it to easily engage with the inner side of the base to provide stability for the support frame 1. A third spring 16 is sleeved on the outer side of the rear end of the abutment block 4, providing driving force for its reset. The front and rear ends of the third spring 16 are located at the front and rear ends of the inner cavity of the abutment groove 17, respectively. A second check valve 15 with a spring structure is horizontally installed in the return oil groove 10, facilitating the return of hydraulic oil from the extrusion oil groove 9 to the main oil groove 8. The one-way end of the second check valve 15 is the extrusion oil groove 9, and a screw 5 is installed at its rear end. The screw 5 controls the flow rate of the return oil from the extrusion oil groove 9 to the main oil groove 8. The front end of the screw 5 abuts against the rear end of the spring structure of the second check valve 15.

[0023] Working Principle: When using this utility model, hydraulic oil is pre-filled into the main oil tank 8, extrusion oil tank 9, and return oil tank 10 at the time of product delivery. Each spring is in its initial state: the first spring 11 (sleeved to the rear end of the T-shaped clamping piece 3), the second spring 12 (sleeved to the upper end of the sliding block 6), and the third spring 16 (sleeved to the rear end of the abutment block 4) are all in a natural or slightly compressed state. The first one-way valve 13 (installed in the extrusion oil tank 9) has a unidirectional flow direction from the main oil tank 8 to the extrusion oil tank 9, preventing hydraulic oil from flowing back. The second one-way valve 15 (installed in the return oil tank 10) prevents the hydraulic oil in the return oil tank 10 from flowing back to the main oil tank 8 through the second one-way valve 15 because the screw 5 is tightly pressed against its own spring structure in the initial state, ensuring the hydraulic oil pressure in the extrusion oil tank 9. The force is stabilized; then the fixed platform 2 at the lower end of the support frame 1 is aligned with the preset slot of the base and pressed down, so that the fixed platform 2 is embedded in the slot; the sliding block 6 drives the T-shaped clamping piece 3 to clamp: when the fixed platform 2 is pressed down, the sliding block 6 in the sliding cavity 14 is pushed upward by the bottom of the slot of the base, and moves upward along the sliding cavity 14, compressing the second spring 12 (at this time, the second spring 12 stores the reset potential energy); during the upward movement of the sliding block 6, the upper two sides of its upper end squeeze the ends of the two T-shaped clamping pieces 3 respectively, forcing the T-shaped clamping pieces 3 to move outward along the displacement cavity 7 towards the outside of the fixed platform 2 (compressing the first spring 11, the first spring 11 stores the reset potential energy), and finally the outer end of the T-shaped clamping piece 3 extends out of the fixed platform 2 and tightly abuts against the inner wall of the slot of the base, realizing the initial clamping of the fixed platform 2 and the base, and providing lateral stability for the support frame 1;

[0024] Next, the sliding block 6 moves upward and simultaneously squeezes the hydraulic oil in the main oil tank 8. After being pressurized, the hydraulic oil in the main oil tank 8 enters the extrusion oil tank 9 through the first one-way valve 13 (due to the one-way flow restriction, the hydraulic oil cannot flow back in reverse). The hydraulic oil pressure in the extrusion oil tank 9 increases, pushing the T-shaped abutment block 4 forward along the extrusion oil tank 9. The front end of the abutment block 4 extends out of the extrusion oil tank 9 and engages with the preset position inside the base (at this time, the rear end of the abutment block 4 compresses the third spring 16, and the third spring 16 stores the reset potential energy), further strengthening the connection between the support frame 1 and the base. Stability is ensured to prevent the support frame 1 from shaking. After installation, under the continuous elastic force of the second spring 12 (attempting to push the sliding block 6 to reset) and the continuous elastic force of the first spring 11 (attempting to pull the T-shaped clamping piece 3 to reset), the T-shaped clamping piece 3 always maintains a pressing force against the inner wall of the base slot. At the same time, the hydraulic oil in the extrusion oil groove 9 maintains a stable pressure due to the check valve 13 and the closed state of the second check valve 15, so that the abutment block 4 continuously clamps against the inner side of the base under the thrust of the hydraulic oil. The double fixation ensures that the support frame 1 is stably installed.

[0025] When the support frame 1 needs to be disassembled, use an external hex wrench to turn the screw 5, causing the screw 5 to move outward and release the contact with the spring structure of the second one-way valve 15. At this time, the one-way ball of the second one-way valve 15 has a movable gap, the circuit oil groove 10 resumes conduction, and the hydraulic oil in the extrusion oil groove 9 can flow back to the main oil groove 8 through the circuit oil groove 10 and the second one-way valve 15. After the hydraulic oil pressure in the extrusion oil groove 9 decreases, the abutment block 4 moves backward along the extrusion oil groove 9 under the action of the reset force of the third spring 16, disengaging from the engagement with the inner side of the base. At the same time, the sliding block 6 moves backward under the action of the reset force of the second spring 12. The sliding block 6 moves downward along the sliding cavity 14, releasing the pressure on the end of the T-shaped clamping piece 3; under the restoring force of the first spring 11, the T-shaped clamping piece 3 moves along the displacement cavity 7 towards the inside of the fixed platform 2, disengaging from the contact with the inner wall of the base slot; finally, the sliding block 6, the T-shaped clamping piece 3, and the contact block 4 are all reset to their initial state, the clamping relationship between the fixed platform 2 and the base slot is released, and the support frame 1 can be easily removed from the base. Through the above process, the quick installation and fixation of the support frame 1 and the base and convenient disassembly are achieved, and the stability during use is ensured by the dual action of mechanical clamping and hydraulic assisted fixation.

[0026] 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.
