Description

Technical Field

[0001] The invention belongs to the technical field of building construction, in particular to an adjustable connecting seat for a multi-curved template. Background Art

[0002] During the casting process, the multi-curved structure needs to be coordinated with the template. However, the special-shaped structure of the multi-curved surface is difficult to be directly shaped by splicing. It also needs to be supported by additional auxiliary parts. The support is preferably an adjustable structure, which can make the template fit the multi-curved structure better and make the casting effect better. For indoor, for example, the inner wall of the pool is usually made into a curved shape for the sake of beauty. Usually, the operator will connect two adjacent wooden boards with hinges, and the curved surface contour can be initially constructed by combining multiple sets of hinges with multiple sets of wooden boards. The wooden boards connected by hinges need to be fixed with nails after the adjustment is completed to ensure the stability of the wooden boards after the fixing is completed. However, when the wooden boards are fixed, if the operator needs to adjust them again, the nails need to be removed again before the wooden boards can be rotated to adjust the angle between the two wooden boards. It is laborious and the angle cannot be flexibly adjusted and changed as needed.

[0003] Therefore, in order to solve the above problems, a multi-curved template adjustable connecting seat is proposed. Summary of the invention

The bottom end of the spring telescopic rod is hinged to the inner wall of the frame. A three-way pipe opening and an L-shaped pipe located above the three-way pipe opening are opened on the column. The bottom end of the U-shaped pipe is connected to the bottom of the frame. The top of the U-shaped pipe can be connected to two arc-shaped pipes through the three-way pipe opening. The arc-shaped pipe, the three-way pipe opening, the U-shaped pipe and the bottom of the frame are all filled with hydraulic oil. The center of the circle of the arc piston rod and the arc pipe is the docking point of the two sets of template bodies.

[0007] Initially, the column moves downward so that the three-way pipe opening is misaligned with the U-shaped pipe and the two groups of arc-shaped pipes respectively.

[0008] Preferably, the connecting assembly comprises a fixed plate fixedly connected to one end of the arc-shaped piston rod, the fixed plate is movably connected to a movable plate, a spring combination limiting rod is fixedly connected to the movable plate, the rod body of the spring combination limiting rod is movably sleeved inside the fixed plate, and the spring part of the spring combination limiting rod is used to support the tendency of the spring combination limiting rod to move toward another spring combination limiting rod;

[0009] The template body is mounted on the moving plate by screws.

[0010] Preferably, the movable plate is also provided with one-way slots at equal intervals, and an elastic piston rod is elastically connected to the inside of the arc-shaped piston rod. One end of the elastic piston rod is located inside the arc-shaped pipe and can contact the hydraulic oil inside the arc-shaped pipe, and the other end of the elastic piston rod is a one-way inclined block and can be inserted into the one-way slot.

[0011] Preferably, a spring member is further provided inside the arc-shaped pipe, and two ends of the spring member are fixedly connected to the arc-shaped pipe and the arc-shaped piston rod respectively.

[0012] Preferably, an L-shaped pipe is opened at the top of the column, hydraulic oil is stored inside the L-shaped pipe, and both ends of the L-shaped pipe are blocked by the inner wall of the frame in the initial state;

[0013] After the L-shaped pipe goes downward, one end thereof is connected with one of the arc-shaped pipes, and the other end is blocked by the inner wall of the frame.

[0014] Preferably, when the spring telescopic rod is pushed upward, the three-way pipe opening is respectively connected with two groups of arc pipes and one U-shaped pipe; when the spring telescopic rod is pushed downward, one end of the L-shaped pipe is connected with one of the arc pipes, and the other end is blocked by the inner wall of the frame.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The above scheme leaves a gap at one end of the two sets of template bodies, rotates the screw rod to push the piston plate to move, and the piston plate injects the hydraulic U-shaped pipe and the three-way pipe mouth at the bottom of the frame into the arc pipe, thereby pushing the arc piston rod to move, and driving the connecting assembly and the template body to rotate with the center of the arc pipe as the axis, to adjust the two sets of connecting assemblies and the template body respectively. When the angle adjustment of the two sets of connecting assemblies and the template body is completed, press the column downward to push the connecting column downward. When the top end of the spring telescopic rod becomes the bottom end, the three-way pipe mouth is dislocated with the arc pipe and the U-shaped pipe respectively, and the connecting column will also keep the relative position unchanged through the elastic force of the spring telescopic rod. At this time, the angle between the two template bodies is fixed, thereby ensuring that the operator can flexibly adjust and change the angle according to needs;

[0020] The above scheme is that after the three-way pipe mouth is misaligned with the arc pipe and the U-shaped pipe respectively, one end of the L-shaped pipe will be connected to one of the arc pipes and the other end will be blocked by the frame. Then, the rotary cover is rotated to drive the column to rotate, so that one end of the L-shaped pipe can be connected to the arc pipe and the other end of the L-shaped pipe can be connected to the U-shaped pipe. At this time, the operator can adjust the angle of one group and the connecting component by rotating the screw. After the adjustment is completed, the operator can fix the adjusted arc pipe, the connecting component and the template body by rotating the rotary cover back to its original position, thereby realizing the individual adjustment of the angle of one group of template bodies.

[0021] The above scheme makes the two groups of template bodies contact at one end relative to each other. At this time, the rotation of the connecting assembly will drive the template bodies to rotate synchronously, and make the ends of the template bodies that are close to each other squeeze each other and move away from each other. At this time, the template body will drive the movable plate to move in the direction away from the other group of template bodies, avoiding the situation that the template bodies cannot rotate due to no gap at one end relative to each other. At the same time, the movement of the movable plate will also cause the one-way slot to squeeze one end of the elastic piston rod to shrink into the inside of the arc-shaped piston rod. When the angle adjustment of the template body is completed, the elastic piston rod will be reset by its own elastic force and be stuck in one of the one-way slots, thereby avoiding the situation that the movable plate will be reset by the elastic force of the spring part of the spring combination limit rod.

[0032] 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.

[0033] like Figures 1 to 9 As shown, the present invention provides an adjustable connection seat for a multi-curved template, comprising an adjustment seat assembly 1 and a template body 3, and further comprising: a connection assembly 2, which is mounted on the adjustment seat assembly 1 and is used to connect the adjustment seat assembly 1 and the template body 3;

[0034] The adjusting seat assembly 1 includes a frame 11, a piston plate 12 is movably connected to the bottom of the frame 11, a screw 121 is connected to a bearing on one side of the piston plate 12, the screw 121 is threadedly connected to the inner wall of the frame 11 and one end extends to the outside of the frame 11, a U-shaped pipe 13 and an arc-shaped pipe 16 are fixedly connected to the frame 11, an arc-shaped piston rod 17 is movably connected inside the arc-shaped pipe 16, one end of the arc-shaped piston rod 17 extends to the outside of the arc-shaped pipe 16 and is connected to the connecting assembly 2, and a column 14 located above the piston plate 12 is movably connected inside the frame 11, and a connecting column is connected to the bottom bearing of the column 14 142, a spring telescopic rod 1421 in an inclined state is hinged inside the connecting column 142, the bottom end of the spring telescopic rod 1421 is hinged to the inner wall of the frame 11, a three-way pipe opening 15 and an L-shaped pipe 141 located above the three-way pipe opening 15 are opened on the column 14, the bottom end of the U-shaped pipe 13 is connected to the bottom of the frame 11, and the top of the U-shaped pipe 13 can be connected to two arc-shaped pipes 16 through the three-way pipe opening 15, and the arc-shaped pipe 16, the three-way pipe opening 15, the U-shaped pipe 13 and the bottom of the frame 11 are all filled with hydraulic oil, and the center of the circle of the arc piston rod 17 and the arc pipe 16 is the docking point of the two sets of template bodies 3;

[0035] Initially, the downward movement of the column 14 can cause the three-way pipe opening 15 to be misaligned with the U-shaped pipe 13 and the two sets of arc-shaped pipes 16;

[0036] By adopting the above scheme, a gap is left at the opposite end of the two groups of template bodies 3, and the screw 121 is rotated to push the piston plate 12 to move. The piston plate 12 will inject the hydraulic U-shaped pipe 13 and the three-way pipe mouth 15 at the bottom of the frame 11 into the arc pipe 16, thereby pushing the arc piston rod 17 to move, and driving the connecting component 2 and the template body 3 to rotate with the center of the arc pipe 16 as the axis to adjust the two groups of connecting components 2 and the template body 3 respectively. When the angle adjustment of the two groups of connecting components 2 and the template body 3 is completed, press the column 14 downward and push the connecting column 142 downward. When the top of the spring telescopic rod 1421 becomes the bottom end, the three-way pipe mouth 15 is respectively misaligned with the arc pipe 16 and the U-shaped pipe 13, and the connecting column 142 will also maintain the relative position unchanged through the elastic force of the spring telescopic rod 1421. At this time, the angle between the two template bodies 3 is fixed, thereby ensuring that the operator can flexibly adjust and change the angle according to needs.

[0037] like Figure 1-Figure 5 and Figure 8 As shown, the connecting assembly 2 includes a fixed plate 21 fixedly connected to one end of the arc-shaped piston rod 17, a movable plate 22 is movably connected to the fixed plate 21, a spring combination limiting rod 24 is fixedly connected to the movable plate 22, a rod body portion of the spring combination limiting rod 24 is movably sleeved inside the fixed plate 21, and a spring portion of the spring combination limiting rod 24 is used to support the tendency of the spring combination limiting rod 24 to move toward another spring combination limiting rod 24;

[0038] The template body 3 is mounted on the moving plate 22 by screws;

[0039] The movable plate 22 is also provided with one-way slots 23 at equal intervals, and the arc-shaped piston rod 17 is elastically connected to an elastic piston rod 171. One end of the elastic piston rod 171 is located inside the arc-shaped pipe 16 and can contact the hydraulic oil inside the arc-shaped pipe 16. The other end of the elastic piston rod 171 is a one-way inclined block and can be inserted into the one-way slot 23.

[0040] A spring member 161 is also provided inside the arc-shaped pipe 16, and two ends of the spring member 161 are fixedly connected to the arc-shaped pipe 16 and the arc-shaped piston rod 17 respectively;

[0041] By adopting the above scheme, by making the two groups of template bodies 3 contact at one end, the rotation of the connecting component 2 will drive the template bodies 3 to rotate synchronously, and make the ends of the template bodies 3 close to each other squeeze each other and move away from each other. At this time, the template body 3 will drive the movable plate 22 to move in the direction away from the other group of template bodies 3, avoiding the situation that the template body 3 cannot rotate due to the lack of gap at one end. At the same time, the movement of the movable plate 22 will also cause the one-way slot 23 to squeeze one end of the elastic piston rod 171 to shrink into the arc-shaped piston rod 17. When the angle adjustment of the template body 3 is completed, the elastic piston rod 171 will be reset by its own elastic force and be stuck in one of the one-way slots 23, thereby avoiding the situation that the movable plate 22 will be reset by the elastic force of the spring part of the spring combination limit rod 24.

[0042] It is worth mentioning that when the arc piston rod 17 needs to move in the opposite direction, the piston plate 12 is driven to move and extract the hydraulic oil in the arc pipe 16, the three-way pipe mouth 15 and the U-shaped pipe 13 by rotating the screw rod 121 in the opposite direction. At this time, the arc piston rod 17 is supported by the elastic force of the spring member 161. The extraction of the hydraulic oil inside the arc pipe 16 will first drive the elastic piston rod 171 to disengage from the U-shaped pipe 13, and then the arc piston rod 17 will shrink, thereby reversely adjusting the angle between the connecting component 2 and the template body 3. At this time, since the elastic piston rod 171 is disengaged from the one-way slot 23, the movable plate 22 and the template body 3 will move toward the other group of template bodies 3 under the elastic force of the spring part of the spring combination limit rod 24, thereby ensuring that when the two groups of template bodies 3 rotate in the opposite direction, the opposite ends can still maintain contact.

[0043] like Figure 3-Figure 9 As shown, an L-shaped pipe 141 is opened at the top of the column 14, and hydraulic oil is stored in the L-shaped pipe 141. Both ends of the L-shaped pipe 141 are blocked by the inner wall of the frame 11 in the initial state;

[0044] After the L-shaped pipe 141 moves downward, one end thereof is connected to one of the arc-shaped pipes 16, and the other end is blocked by the inner wall of the frame 11;

[0045] When the spring telescopic rod 1421 pushes upward, the three-way pipe opening 15 is connected with two groups of arc pipes 16 and one U-shaped pipe 13 respectively; when the spring telescopic rod 1421 pushes downward, one end of the L-shaped pipe 141 is connected with one of the arc pipes 16, and the other end is blocked by the inner wall of the frame 11;

[0046] The top bearing of the frame 11 is connected with a rotary cover 111. Four L-shaped pipes 141 are arranged in a circumferential array on the top of the frame 11. The rotary cover 111 is elastically connected with an elastic block 1111 that can be inserted into the bayonet 112. The top of the column 14 is spline-connected with the rotary cover 111.

[0047] A fine-tuning assembly 4 is also provided on the top of the fine-tuning assembly frame 11; the fine-tuning assembly 4 includes a cavity 41 opened on the top of the frame 11, a piston plate 42 is movably connected inside the cavity 41, a screw 43 is connected to the top bearing of the piston plate 42, the screw 43 is threadedly connected to the frame 11, and the top of the screw 43 extends to the top of the frame 11;

[0048] Hydraulic oil is stored inside the cavity 41 and the bottom end of the cavity 41 is connected to the L-shaped pipe 141;

[0049] By adopting the above scheme, after the three-way pipe opening 15 is misaligned with the arc pipe 16 and the U-shaped pipe 13 respectively, one end of the L-shaped pipe 141 will be connected to one of the arc pipes 16 and the other end will be blocked by the frame 11, and then the rotary cover 111 is rotated to drive the column 14 to rotate, so that one end of the L-shaped pipe 141 can be connected to the arc pipe 16, and the other end of the L-shaped pipe 141 can be connected to the U-shaped pipe 13. At this time, the operator can adjust the angle of one group and the connecting component 2 of the template body 3 by rotating the screw 121. After the adjustment is completed, the operator can fix the adjusted arc pipe 16, the connecting component 2 and the template body 3 by rotating the rotary cover 111 back to its original position, thereby realizing the individual adjustment of the angle of one group of template bodies 3;

[0050] At the same time, since the elastic block 1111 can be inserted into the slot 112, it is also convenient for operators to judge the accuracy of the rotation position.

[0051] The working principle and use process of the present invention:

[0052] When there is a gap at one end of the two sets of template bodies 3, the operator first fixes the frame 11 and connects the template body 3 with the adjustment seat assembly 1 through the connecting assembly 2. The operator rotates the screw 121 to push the piston plate 12 to move. The piston plate 12 will inject the hydraulic U-shaped pipe 13 and the three-way pipe mouth 15 at the bottom of the frame 11 into the arc pipe 16, thereby pushing the arc piston rod 17 to move, and drive the connecting assembly 2 and the template body 3 to rotate with the center of the arc pipe 16 as the axis to adjust the two sets of connecting assemblies 2 and the template body 3 respectively. When the angle adjustment of the two sets of connecting assemblies 2 and the template body 3 is completed, press the column 14 downward and push the connecting column 142 downward. When the top of the spring telescopic rod 1421 becomes the bottom end, the three-way pipe mouth 15 is respectively misaligned with the arc pipe 16 and the U-shaped pipe 13, and the connecting column 142 will also keep the relative position unchanged through the elastic force of the spring telescopic rod 1421. At this time, the angle between the two template bodies 3 is fixed;

[0053] When the three-way pipe opening 15 is misaligned with the arc pipe 16 and the U-shaped pipe 13 respectively, one end of the L-shaped pipe 141 will be connected to one of the arc pipes 16 and the other end will be blocked by the frame 11. When it is necessary to adjust the angle of one group of template bodies 3, the rotating cover 111 drives the column 14 to rotate, so that one end of the L-shaped pipe 141 can be connected to the arc pipe 16 and the other end of the L-shaped pipe 141 can be connected to the U-shaped pipe 13. At this time, the operator can adjust the angle of one group and the connecting component 2 of the template body 3 by rotating the screw 121. After the adjustment is completed, the operator can fix the adjusted arc pipe 16, the connecting component 2 and the template body 3 by rotating the rotating cover 111 back to its original position;

[0054] There is no gap between the two groups of template bodies 3 at one end. At this time, the rotation of the connecting component 2 will drive the template bodies 3 to rotate synchronously, and make the ends of the template bodies 3 that are close to each other squeeze each other and move away from each other. At this time, the template body 3 will drive the movable plate 22 to move in the direction away from the other group of template bodies 3, to avoid the situation where the template body 3 cannot rotate due to no gap at one end. At the same time, the movement of the movable plate 22 will also cause the one-way slot 23 to squeeze one end of the elastic piston rod 171 to shrink to the inside of the arc-shaped piston rod 17. When the angle adjustment of the template body 3 is completed, the elastic piston rod 171 will be reset by its own elastic force and be stuck in one of the one-way slots 23, thereby avoiding the situation where the movable plate 22 will be reset by the elastic force of the spring part of the spring combination limit rod 24.

[0055] When the arc piston rod 17 needs to move in the opposite direction, the piston plate 12 is driven to move by the reverse rotation of the screw rod 121 and the hydraulic oil in the arc pipe 16, the three-way pipe port 15 and the U-shaped pipe 13 is extracted. At this time, the arc piston rod 17 is supported by the elastic force of the spring member 161. The extraction of the hydraulic oil inside the arc pipe 16 will first drive the elastic piston rod 171 to disengage from the U-shaped pipe 13, and then the arc piston rod 17 will contract, thereby reversely adjusting the angle between the connecting component 2 and the template body 3. At this time, since the elastic piston rod 171 is disengaged from the one-way slot 23, the movable plate 22 and the template body 3 will move toward the other group of template bodies 3 under the elastic force of the spring part of the spring combination limit rod 24, thereby ensuring that when the two groups of template bodies 3 rotate in the opposite direction, the opposite ends can still maintain contact.
