DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] Embodiment 1: This embodiment provides a support base for an assembled building, specifically Figure 1-Figure 5 As shown, it includes a support seat 1 and a fixed column 2, the fixed column 2 is installed on the support seat 1, the support seat 1 includes a shell 101, a horizontal buffer unit is installed on the shell 101, and a vertical buffer unit and a support table 103 are installed on the horizontal buffer unit; the horizontal buffer unit includes a base 106, the base 106 is fixedly installed on the shell 101, a fixed buffer table 107 is installed on the base 106, the fixed buffer table 107 is slidably connected to a limiting sleeve 112, and the limiting sleeve 112 is slidably connected to a movable buffer table 110, and the function of the limiting sleeve 112 is to ensure that the fixed buffer table 107 and the movable buffer table 110 is coaxial, the limiting sleeve 112 is equipped with a ball pair sleeve 120, and the ball pair on the ball pair sleeve 120 is connected to a ball rod 116; the movable buffer platform 110 is equipped with a moving seat 115, the moving seat 115 is slidably connected to the second moving platform 114, the second moving platform 114 is slidably connected to the first moving platform 113, the ball rod 116 cooperates with the first moving platform 113, and the support platform 103 is installed on the first moving platform 113; a plurality of buffer cylinders are hinged on the housing 101, and the buffer cylinders are rotatably connected to the synchronous sleeve 119, and the synchronous sleeve 119 cooperates with the ball rod 116. The housing 101 is provided with an openable maintenance window for later maintenance.

[0026] When in use, first insert the fixed column 2 into the carrier, which can be an ordinary ground or a prefabricated foundation, etc., and then place the prefabricated building on the support platform 103. At this time, the support platform 103 is subjected to the pressure of the prefabricated building, and the vertical buffer unit starts to work to provide longitudinal support and buffering for the support platform 103. At the same time, due to the pressure on the vertical buffer unit, the movable buffer platform 110 begins to descend, that is, the movable buffer platform 110 and the fixed buffer platform 107 begin to move closer. Here, the length of the end of the ball rod 116 close to the synchronous sleeve 119 from the ball sleeve 120 is greater than the length of the end of the ball rod 116 close to the first movable platform 113 from the ball sleeve 120, so that the ball sleeve 120 is used as a fulcrum to form a lever.

[0027] When the building shakes due to situations including but not limited to earthquakes, the vertical buffer unit will buffer the longitudinal displacement of the building to prevent fractures in the connection; when horizontal shaking displacement occurs, the support platform 103 drives the first mobile platform 113 to slide on the second mobile platform 114, and the second mobile platform 114 slides on the mobile platform seat 115. The vertical sliding of the first mobile platform 113 and the second mobile platform 114 ensures that the first mobile platform 113 can move in all directions in the horizontal direction. When the first movable platform 113 moves, the first movable platform 113 will drive the end of the ball rod 116 to move, and at this time the ball rod 116 will swing at the connection with the ball pair sleeve 120. When the ball rod 116 swings, the ball rod 116 will drive the synchronous sleeve 119 to move in the horizontal plane. At this time, multiple buffer cylinder bodies 105 will buffer and hinder the movement of the synchronous sleeve 119, that is, they will apply resistance to the movement of the first movable platform 113, and finally achieve buffering of the movement of the support platform 103, so that the building on the support platform 103 can be slightly displaced to reduce the stress caused by the shaking on the building, and prevent the building from cracking and damage. The buffer cylinder 105 here has a reset function. When the shaking ends, the buffer cylinder 105 resets, so that the ball rod 116 drives the support platform 103 to reset, and the prefabricated building will return to the initial position; and due to the lever principle, and the longer length from the ball sleeve 120 to the end close to the synchronous sleeve 119 on the ball rod 116, it is more labor-saving when buffering the displacement of the support platform 103. Compared with the existing horizontal buffering that only uses a circular array of springs, this device is not easy to rust because it has no exposed springs, and later maintenance is more convenient; at the same time, the use of the lever principle can make buffering more labor-saving and convenient; based on the lever principle, the use of multiple buffer cylinders 105 hinged on the housing 101 can achieve all-round and dead-angle buffering of the support platform 103 moving in the horizontal plane, and the buffering effect is better.

[0028] Embodiment 2: This embodiment further expands the vertical buffer unit on the basis of the above embodiment. Figure 3-Figure 4As shown, the vertical buffer unit includes a buffer frame 104, a first connecting rod 108, and a second connecting rod 109. The buffer frame 104 is installed on the limiting sleeve 112. The limiting sleeve 112 is slidably connected to a slider 117. A longitudinal buffer spring 118 is arranged between the slider 117 and the limiting sleeve 112. One end of the second connecting rod 109 is rotatably connected to the movable buffer platform 110, and the other end is rotatably connected to the slider 117; one end of the first connecting rod 108 is rotatably connected to the fixed buffer platform 107, and the other end is rotatably connected to the slider 117.

[0029] When the prefabricated building is placed on the support platform 103, the support platform 103 is compressed, and the pressure is transmitted to the movable buffer platform 110 through the first mobile platform 113, the second mobile platform 114, and the mobile platform seat 115 in sequence. At this time, the movable buffer platform 110 presses down the second connecting rod 109, and the second connecting rod 109 pushes the slider 117 to move on the buffer frame 104. At this time, the longitudinal buffer spring 118 is compressed to achieve buffering of the support platform 103. At the same time, the movement of the slider 117 drives the first connecting rod 108, so that the buffer frame 104 and the limiting sleeve 112 move downward synchronously. During the descent of the limiting sleeve 112, the ball sub-sleeve 120 will be driven to make the ball rod 116 descend synchronously, and the ball rod 116 slides in the synchronous sleeve 119 and the first mobile platform 113. When the building shakes, the movable buffer platform 110 moves up and down, and at this time, the longitudinal buffer spring 118 will still buffer the movement of the slider 117.

[0030] Through the above arrangement, the spring between the movable buffer platform 110 and the fixed buffer platform 107 can be changed from vertical to horizontal, that is, the arrangement of the spring has a larger space and is not restricted by the original space.

[0031] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0032] Embodiment 3: This embodiment further expands the buffer cylinder on the basis of the above embodiment. Figure 6 As shown, the buffer cylinder includes a buffer cylinder body 105 and a buffer cylinder rod 122. The buffer cylinder rod 122 is slidably connected to the buffer cylinder body 105. The buffer cylinder body 105 is hinged on the shell 101. The buffer cylinder rod 122 is rotatably connected to the synchronization sleeve 119. The buffer cylinder rod 122 is provided with a piston plate 123, and the piston plate 123 divides the buffer cylinder body 105 into two cavities; the inner wall of the buffer cylinder body 105 is provided with a plurality of connecting oil grooves 121, and the connecting oil grooves 121 are shallow at both ends and deep in the middle. The oil in the two cavities is connected through the connecting oil grooves 121.

[0033] When the ball rod 116 swings, the synchronous sleeve 119 will also move horizontally. At this time, multiple buffer cylinder bodies 105 will be subjected to forces. According to the swinging direction of the ball rod 116, some buffer cylinder bodies 105 will be subjected to tension, while some buffer cylinder bodies 105 will be subjected to pressure. However, no matter what kind of force the buffer cylinder body 105 is subjected to, the piston plate 123 will move in the buffer cylinder body 105. The initial position of the piston plate 123 is in the middle of the connecting oil groove 121. At this time, the cross-sectional area of ​​the connecting oil groove 121 at the connecting point between the two cavities is the largest. After the piston plate 123 moves, the cross-sectional area of ​​the connecting oil groove 121 at the connecting point between the two cavities will be reduced. The longer the moving distance of the piston plate 123, the smaller the cross-sectional area of ​​the connecting oil groove 121 at the connecting point will be, that is, the resistance to the flow of oil between the two cavities will be greater, thereby achieving a buffering effect. When the shaking stops, the first reset spring 124 will reset the piston plate 123.

[0034] Through the above arrangement, the buffering effect of the buffer oil cylinder body 105 changes linearly. The more severe the support platform 103 shakes, the more obvious the buffering effect of the buffer oil cylinder body 105 is. That is, the buffering force can be adaptively changed according to the intensity of the shaking of the prefabricated building, and its buffering effect is better.

[0035] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0036] Embodiment 4: This embodiment further expands the fixing column 2 on the basis of the above embodiment. Figure 7-Figure 9 As shown, the fixing column 2 includes a fixing column body 201 , on which a pressing part and a pop-up part are installed; the pop-up part is ejected radially along the fixing column body 201 by using the pressing part, so that the fixing column 2 firmly holds the carrier.

[0037] The extrusion part includes an extrusion rod 202 and a second return spring 203. The extrusion rod 202 is slidably connected to the fixed column 201. The second return spring 203 is arranged between the extrusion rod 202 and the fixed column 201. The extrusion rod 202 is provided with a plurality of protrusion blocks 205. The pop-up part includes an pop-up claw seat 204. The pop-up claw seat 204 is rotatably connected to the fixed column 201. A plurality of pop-up claws 206 are rotatably connected to the pop-up claw seat 204. A spiral groove 207 is provided on the pop-up claw seat 204. The protrusion block 205 cooperates with the spiral groove 207.

[0038] When the extrusion rod 202 is compressed, the extrusion rod 202 moves downward. At this time, the raised block 205 on the extrusion rod 202 begins to slide in the spiral groove 207 on the pop-up claw seat 204, so that the pop-up claw seat 204 begins to rotate. When the pop-up claw seat 204 rotates, it will drive the pop-up claw 206 to move. Since a limiting hole for the pop-up claw 206 to pop out is provided on the fixed column 201, the pop-up claw 206 will extend out of the fixed column 201 when it moves, that is, the pop-up claw 206 will be embedded in the carrier, and the carrier here is ordinary soil ground. When the pop-up claw 206 is embedded therein, when the building is shaking, the device has better stability to prevent the support base 1 from tipping over.

[0039] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0040] Embodiment 5: This embodiment is further expanded on the basis of the above embodiment. Figure 7 As shown, the synchronous sleeve 119 is slidably connected to the extrusion plate 111 , the extrusion plate 111 cooperates with the ball rod 116 , and the extrusion plate 111 abuts against the extrusion rod 202 .

[0041] When the prefabricated building is placed on the support platform 103, the movable buffer platform 110 and the limiting sleeve 112 will move downward. When the limiting sleeve 112 moves downward, it drives the ball rod 116 to move downward. At this time, the ball rod 116 will squeeze the squeezing plate 111, and the squeezing plate 111 squeezes the squeezing rod 202, so that the pop-up claw 206 is automatically popped out after the prefabricated building is installed. When the prefabricated building is taken away, the ball rod 116 is reset upward, and the compressed second reset spring 203 will pop up and reset the squeezing rod 202, that is, the pop-up claw 206 will also retract, making it easy to take away the device.

[0042] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0043] Embodiment 6: This embodiment is further expanded on the basis of the above embodiment. Figure 2 As shown, a sealing ring 102 is provided between the housing 101 and the support platform 103. The sealing ring 102 is elastic, and when the support platform 103 is compressed, the sealing ring 102 is also compressed, thereby enhancing the sealing performance of the sealing ring 102 between the support platform 103 and the housing 101. The sealing with the sealing ring 102 can prevent rainwater from penetrating into the housing 101 and causing rust to the components.

[0044] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0045] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the protection scope of the present invention.
