Description

Technical Field

[0001] The utility model relates to a disc buckle frame support, in particular to a self-adaptive disc buckle frame support device. Background Art

[0002] When building a disc buckle frame, you need to lay the support first, then install the starting rod, and then build the mopping rod. After installing the mopping rod, you need to use a level to measure, and adjust the nut of the support to ensure that the sweeping rod is horizontal, and then gradually install the foundation pole, horizontal and vertical horizontal poles, etc. For flat working conditions, the construction of the disc buckle frame is relatively simple, but for sloped surfaces, the chassis of the existing disc buckle frame cannot fit the slope setting. In order to adapt to the slope, wooden wedges are usually inserted under the chassis, but due to the lack of a fixed connection between the wooden wedge and the chassis, it is easy to shift during use, and the slope of the ramp at the construction site is different. Using wooden wedges to support the chassis is not difficult to meet the support requirements at different angles, and the operation is difficult, and there are safety risks during use. In addition, at the construction site, wooden wedges are easy to lose, and remaking requires special cutting tools and wood, which also takes time and manpower, which will seriously reduce construction efficiency. Summary of the invention

[0003] The purpose of the utility model is to provide an adaptive disc buckle frame support device, which can be used for the construction of the disc buckle frame under flat working conditions and can also be used for the construction of the disc buckle frame under slope working conditions. Its ingenious structural design can make the base part automatically adapt to different slopes and can achieve stable support. The entire deformation process is simple and easy to operate, thereby solving the problems raised in the above-mentioned background technology.

[0004] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adaptive disc buckle frame support device, including a support rod with an external thread and an adjusting thread sleeve threadedly connected to the support rod, and a base is fixedly arranged at the lower end of the support rod. The base is an adaptive chassis assembly, including an upper fixed bottom plate and a lower flip bottom plate, wherein the support rod is vertically welded to the middle of the front of the fixed bottom plate, and is hingedly connected to the left end of the fixed bottom plate through a hinge; the flip bottom plate is parallel to the fixed bottom plate in a closed state, and can be flipped downward around the axis of the hinge under the action of gravity to fit the slope surface; the adaptive chassis assembly also includes a support rod assembly arranged on the right side of the flip bottom plate, and a limiting structure arranged on the fixed bottom plate, wherein the support rod assembly has a positioning portion, and when the flip bottom plate is flipped to fit the slope surface, the limiting structure can cooperate with the positioning portion and lock the support rod assembly, thereby limiting the upward movement of the support rod assembly.

[0005] In the above technical scheme, the base arranged at the lower end of the support rod includes a fixed base plate above and a flip base plate below, and the left end of the flip base plate is hingedly connected to the left end of the fixed base plate. Therefore, under the action of gravity, the flip base plate will automatically flip down to fit the slope surface under the constraint of the hinge, thereby achieving the purpose of the base adapting to the slope surface; in addition, a support rod assembly is arranged on the right side of the flip base plate, and a limiting structure is arranged on the fixed base plate. When the flip base plate is flipped into place, the limiting structure locks the support rod assembly by cooperating with the positioning part on the support rod assembly. At this time, the support rod assembly reversely supports the flip base plate that fits the slope surface. In this solution, the fixed base plate, the flip base plate, the support rod assembly and the limiting structure together constitute a new base, which as a whole occupies a small space, and when the flip base plate is in a closed state, it is parallel to the fixed base plate. At this time, the entire support device can support the disc buckle frame on the flat ground, and when the working environment is on a slope, the flip base plate can automatically fit the slope surface and remain stable under the action of the support rod assembly and the limiting structure, so it is suitable for slope surfaces. The deformation process is simple and easy to operate, and the state after deformation is stable, which can improve both construction efficiency and safety.

[0006] As a preferred solution, the hinge axis of the hinge is located between the fixed bottom plate and the flip bottom plate. When the flip bottom plate is in a closed state, there is a reserved space between the flip bottom plate and the fixed bottom plate, and the limiting structure is located in the reserved space; the support rod assembly is arc-shaped, and the center of the virtual circle where it is located is located on the axis of the hinge axis of the hinge, and the positioning portion is arranged on the inner arc surface of the support rod assembly. The limiting structure is arranged in the reserved space between the flip bottom plate and the fixed bottom plate, which can prevent cement and the like from falling on the limiting structure and affecting its function. The support rod assembly is arranged in the above arc shape so that when the flip bottom plate is flipped, the support rod assembly and the fixed bottom plate maintain the same distance, so that the support rod assembly and any positioning portion on the support rod assembly have the same matching relationship, thereby ensuring the stability of the locked state.

[0007] For the solution using an arc-shaped support rod assembly, it is preferred that the support rod assemblies have two and are symmetrically arranged in the width direction of the flip base plate; in addition, two limiting holes are arranged on the right side of the fixed base plate, the support rod assembly passes through the corresponding limiting holes, and the outer arc surface of the support rod assembly facing away from the positioning portion contacts the inner wall of the limiting hole, and when the support device is supported on the slope surface, the support rod assembly reversely supports the flip base plate below. At this time, the right side wall of the limiting hole provides supporting force to the support rod assembly, which can effectively prevent the support rod assembly from deforming to the right.

[0008] As a preferred embodiment, the support rod assembly includes a hinge seat at the bottom and a positioning strip at the top, wherein the hinge seat is fixedly arranged on the front side of the flip base plate, and its hinge axis is parallel to the hinge axis of the hinge part, and the lower end of the positioning strip is hingedly connected to the corresponding hinge seat, and the limit of its flipping to the right is that the entire support rod assembly presents the arc shape; when the flip base plate is in a closed state, the upper part of the hinge seat passes through the limiting hole, and the positioning strip can be flipped to the left to fit the front side of the fixed base plate, so that the entire adaptive chassis assembly can store the positioning strip, which can avoid the support rod assemblies that are tilted when the support device is stored in a centralized manner and hooked with each other; in addition, when the positioning strip is pressed on the fixed base plate, the positioning strip can play a limiting role, so that the flip base plate maintains a closed state parallel to the fixed base plate, and when the two positioning strips are flipped at the same time to be on the same arc line with the hinge seat below, the flip base plate will automatically fall.

[0009] As a preferred solution, a longitudinally penetrating avoidance hole is set on the fixed base plate, and a joystick is movably set in the avoidance hole. The lower end of the joystick is connected to the limiting structure, and the locking of the supporting rod assembly by the limiting structure can be released by pushing the joystick.

[0010] For a preferred solution of the support device using the above-mentioned positioning part and support rod assembly, the positioning part is preferably a plurality of positioning teeth arranged on the inner arc surface of the support rod assembly, the positioning teeth are arranged in the full length in the width direction of the support rod assembly, and a positioning slot is formed between adjacent positioning teeth, and the opening of the positioning slot faces the hinge axis of the hinge; the limiting structure includes an insert that movably fits the back of the fixed bottom plate, and also includes an elastic member, and the elastic member provides a rightward thrust to the insert, so that the right end of the insert is inserted into the corresponding positioning slot, thereby locking the support rod assembly. By pushing the insert backward, the insert is disengaged from the positioning strip, and the entire flip bottom plate can be smoothly flipped downward at this time. When the flip bottom plate is flipped to fit the slope surface, the right end of the insert is inserted into the corresponding positioning slot after the insert is released, thereby locking the support rod assembly.

[0011] As a preferred solution, a prefabricated screw hole is longitudinally arranged on the plug-in component, and the operating rod is a reset screw with a threaded section at the lower end, and the threaded section is installed in cooperation with the prefabricated screw hole. By tightening the reset screw, the positioning plate can be made to fit tightly against the fixed base plate, thereby fixing the positioning plate. Therefore, it can be ensured that the positioning plate locks the support rod assembly stably and reliably, preventing the support device from accidentally loosening during construction.

[0012] As a preferred solution, the side of the positioning slot facing the hinge is the bottom surface of the slot, and in the width direction of the support rod assembly, the bottom surface of the slot is constructed as a bilaterally symmetrical inverted V-shaped slope, so that the middle of the bottom surface of the slot is high and the two sides are low, and in the locked state, the right end surface of the positioning plate only contacts the middle of the bottom surface of the slot. When the positioning slot facing the plug-in is filled with fillers such as cement and soil, the positioning plate can be made to hit the filler by repeatedly pushing it backward and then releasing it. Since the bottom of the positioning slot is an inverted V-shaped bottom surface of the slot, when the positioning plate hits the cement filler, the cement filler will move to both sides along the bottom surface of the slot, so that the cement filler can be quickly cleaned off.

[0013] For another preferred scheme of the support device using the above-mentioned positioning part and support rod assembly, the positioning part is a meshing tooth arranged on the inner arc surface of the support rod assembly, and the meshing tooth is arranged along the entire length of the width direction of the support rod assembly; the limiting structure is a pawl mechanism arranged on the back side of the fixed base plate, and the pawl mechanism includes two pawls contacting the meshing teeth, and the two pawls are fixedly connected to the same mounting shaft, which is arranged along the width direction of the support rod assembly and movably installed in an axis seat arranged on the back side of the fixed base plate; a torsion spring is mounted on the mounting shaft, and the torsion spring provides a pre-tightening force for the pawl to rotate counterclockwise. During the process of flipping the flip base plate downward, as the support rod assembly moves downward, the meshing teeth will force the pawl to move in the clockwise direction, and under the action of the torsion spring, the pawl will quickly reset counterclockwise and contact the meshing teeth. In this process, the pawl will clean up the cement and other attachments between the meshing teeth. According to the working principle of the pawl, the support rod assembly can only move downward but not upward. Therefore, when the flip base plate is flipped to fit the slope surface, the pawl will touch the corresponding meshing teeth, thereby realizing the positioning of the flip base plate.

[0014] As a preferred solution, the operating rod is an operating handle, the lower end of which is fixedly connected to the mounting shaft, and the ratchet can be disengaged from the meshing teeth by pushing the operating handle to the right, so that the support device can be quickly disassembled and stored.

DETAILED DESCRIPTION

[0031] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0032] Figure 1 The schematic diagram of the planar structure of the first embodiment provided by the utility model is as follows: Figure 1 As shown, the adaptive disc buckle support device includes a support rod 1 with external threads and an adjusting threaded sleeve 2 threadedly connected to the support rod 1, and a base is fixedly arranged at the lower end of the support rod 1, wherein the adjusting threaded sleeve 2 includes an extension handle symmetrically arranged in the left and right in addition to the threaded sleeve in the middle, so as to manually rotate the adjusting threaded sleeve 2. The base of the adaptive disc buckle support device is the focus of this embodiment, which is a composite adaptive chassis component 3 different from the existing support, including an upper fixed bottom plate 4 and a lower flip bottom plate 5. Figure 8 As shown, a support rod 1 is vertically welded to the middle of the front of the fixed bottom plate 4. In order to improve the structural strength of the fixed bottom plate 4, four reinforcing ribs 41 are arranged around the support rod 1. The flip bottom plate 5 is hingedly connected to the left end of the fixed bottom plate 4 through a hinge 6. Figure 1 and Figure 2 It can be seen that the hinge 6 extends along the width direction of the flip base plate 5, and its hinge axis is located between the fixed base plate 4 and the flip base plate 5. When the flip base plate 5 is in a closed state, the flip base plate 5 remains parallel to the fixed base plate 4, and there is a reserved space between the two. Therefore, the disk buckle rack support device can support the disk buckle rack in a plane working condition like the existing support.

[0033] like Figure 3As shown, on the right side of the fixed bottom plate 4, two rectangular limiting holes 42 are symmetrically arranged in the width direction, and a waist-shaped avoidance hole 43 extending in the left-right direction is arranged between the limiting hole 42 and the adjusting threaded sleeve 2, wherein the limiting hole 42 is used for the support rod assembly 7 to pass through, and the avoidance hole 43 is used for the reset screw 8 to pass through, and the reset screw 8 is used to control the plug-in member arranged on the back of the fixed bottom plate 4. Specifically, the support rod assembly 7 is arranged at the right end of the flip bottom plate 5, and the setting position corresponds to the limiting hole 42 one by one.

[0034] like Figure 4 As shown, the support rod assembly 7 is an arc-shaped as a whole, the center of the virtual circle in which it is located is located on the axis of the hinge shaft of the hinge 6, and a positioning portion is provided on the inner arc surface of the support rod assembly 7 (i.e., the side close to the hinge 6); the entire support rod assembly 7 is divided into an upper positioning strip 71 and a lower hinge seat 73, wherein the hinge seat 73 is fixedly welded on the flip bottom plate 5, and as shown Figure 5 As shown, shoulders 78 are provided on both sides of the hinge seat 73 for keeping the flip bottom plate 5 and the fixed bottom plate 4 parallel and closed; Figure 5 As can be seen in the figure, the upper end of the hinge seat 73 is provided with a hinge shaft 75, and the positioning bar 71 is installed on the hinge shaft 75 through the hinge shaft hole 76 provided at the lower end, so that the positioning bar 71 can be turned to the left, and the limit of its turning to the right is that the entire support rod assembly 7 is in an arc shape. Figure 2 It can be seen that when the flip base plate 5 is in a closed state, the upper end of the hinge seat 73 is inserted into the corresponding limiting hole 42. At this time, the shoulder 78 supports the lower edge of the limiting hole 42, and the positioning strip 71 can be flipped to the top end to press on the fixed base plate 4. Therefore, the support rod assembly 7 in this embodiment can be folded and stored, and the positioning strip 71 at this time can play a limiting role, so that the flip base plate 5 maintains a closed state parallel to the fixed base plate 4. When the two positioning strips 71 are flipped at the same time to be on the same arc line with the hinge seat 73 below, the flip base plate 5 will automatically fall.

[0035] In the first embodiment, the positioning portion is composed of a plurality of positioning teeth 72. Figure 5 and Figure 6 It can be seen that in this embodiment, only the positioning teeth 72 are provided on the positioning strip 71, and are provided along the entire width direction of the positioning strip 71, and three-sided open positioning slots 74 are formed between these positioning teeth 72, and these positioning slots 74 are all oriented toward the hinge axis of the hinge 6. Figure 6 As shown, the bottom of the positioning slot 74 is a slot bottom surface 79 . In the width direction of the support rod assembly 7 , the slot bottom surface 79 is constructed as a left-right symmetrical inverted V-shaped slope surface, so that the middle of the slot bottom surface 79 is high and the two sides are low.

[0036] Based on the positioning strip 71 of the above structure, the plug-in member in the first embodiment adopts Figure 7The positioning plate 10 shown in the figure specifically has two parallel guide rails 11 symmetrically arranged in the width direction of the fixed base plate 4. The two sides of the positioning plate 10 are movably clamped in the guide rails 11 and the back side is in contact with the fixed base plate 4. A prefabricated screw hole 15 is arranged in the middle of the positioning plate 10. The lower end of the aforementioned reset screw 8 is threadedly connected to the prefabricated screw hole 15. Therefore, the positioning plate 10 can be controlled to move forward and backward by moving the reset screw 8 forward and backward. In addition, the positioning plate 10 can be fixed in contact with the fixed base plate 4 by tightening the reset screw 8 to lock the positioning plate 10. In addition, as Figure 7 As shown, two V-shaped springs 12 are arranged on the right side of the positioning plate 10, the middle part of the V-shaped spring 12 is sleeved on the central axis 13, the right end touches the limiting hole arranged on the right end face of the positioning plate 10, and the left end is pressed on the positioning axis 14, and the two V-shaped springs 12 are always in a compressed state. Therefore, the two V-shaped springs 12 will push the positioning plate 10 to move to the right until it is inserted into the corresponding positioning slot 74.

[0037] In the above-mentioned structure of the adaptive disk buckle support device, in order to improve the friction of the support on the slope surface, an anti-skid pad 9 (such as a rubber pad) is set on the back of the flip bottom plate 5, and the anti-skid pad 9 is installed by screws, which is convenient for regular replacement. In the case of building a disk buckle frame on a flat surface, the support device with the flip bottom plate 5 in a closed state is placed on the flat surface, and then the starting rod 100 is sleeved on the support rod 1, and then the sweeping rod is installed on the starting rod 100, and then the adjusting nut 2 is adjusted to make the sweeping rod horizontal. At this time, the anti-skid pad 9 is pressed tightly against the ground, and the use state of the entire support device is as follows: Fig. 9 As shown. In the case of installing the buckle frame on a slope, make the left end of the flip base plate 5 contact the slope surface (high place), then tighten the adjustment nut 2, and then flip the two folded positioning strips 71 to the right to the maximum angle, and then push the reset screw 8 to the left until the positioning plate 10 is separated from the support rod assembly 7. At this time, the entire flip base plate 5 will flip down to fit the slope surface under the action of gravity. At this time, release the reset screw 8, and the positioning plate 10 moves to the right under the push of the V-shaped spring 12 until the front end is inserted into the corresponding positioning slot 74, thereby locking the positioning strip 71. At this time, the flip base plate 5 is in Fig.10 The stable open state shown; since the outer arc surface of the positioning strip 71 contacts the side wall of the limiting hole 42, the limiting hole 42 can provide support for the positioning strip 71, thereby improving the anti-deformation ability of the positioning strip 71. In addition, after repeated use, the positioning slot 74 may be filled with cement. In this case, by moving the positioning plate 10 to the left and then releasing it, the positioning plate 10 can hit the cement filler. Since the bottom of the positioning slot 74 is an inverted V-shaped groove bottom surface 79, when hit, the cement filler will move to both sides along the groove bottom surface 79 (cracked or crushed due to uneven acceptance), so that the cement filler can be quickly cleaned.

[0038] The utility model also provides a second embodiment, and the difference between the second embodiment and the first embodiment lies in the positioning part and the limiting structure of the two. Fig.11 As shown, the positioning portion is a meshing tooth 741 provided on the inner arc surface of the positioning strip 71, and the meshing tooth 741 is also provided on the inner arc surface of the hinge seat 73. Fig.12 As shown, the limiting structure is a pawl mechanism arranged on the back of the fixed base plate 4, and the pawl mechanism includes two pawls pointing to the lower right, and the two pawls 101 are fixedly connected to the same mounting shaft 102, and the mounting shaft 102 is arranged along the width direction of the support rod assembly 7, and is movably installed in the shaft seat 103 arranged on the back of the fixed base plate 4; in addition, a torsion spring 104 is set on the mounting shaft 102, one end of the torsion spring 104 is limited by the shaft seat 103, and the other end is limited by the spring positioning block 10 on the mounting shaft 102, and provides a counterclockwise rotation preload force to the pawl 101, as shown in FIG. Fig.13 As shown, the end of the pawl 101 automatically meshes with the meshing tooth 741. It should be noted that, since the meshing tooth 741 is also provided on the hinge seat 73, the second embodiment can meet the small angle deflection requirements of the flip bottom plate 5, that is, it can adapt to any slope of 0°-15° (the maximum use angle of the support device in this embodiment is 15°). In addition, the joystick of the second embodiment is also different from that of the first embodiment. Fig.12 In the embodiment, the operating handle 81 passes longitudinally through the avoidance hole 43, and the lower end is fixedly connected to the mounting shaft 102. Fig.14 In the use state shown, when the support device needs to be disassembled, the operating handle 81 is pulled to the right to disengage the pawl 101 from the positioning strip 71. At this time, the disassembly and assembly can be completed by lifting the flip bottom plate 5 and then folding the positioning strip 71 to the left.

[0039] In the above two embodiments, two support rod assemblies 7 are used to support the fixed base plate 4, and the two support rod assemblies 7 are symmetrically arranged at positions close to the edge of the flip base plate 5, so that the fixed base plate 4 can maintain force balance during use. During construction, a starting rod 100 is installed on the top of each disc buckle frame support device (here, the starting rod 100 is directly mounted on the support rod 1, and the lower part is supported by the adjusting threaded sleeve 2, so the smaller the gap between the support rod 1 and the inner wall of the starting rod 100, the more stable the support device supports the disc buckle frame), the adjacent starting rods 100 are connected by a sweeping rod, and the upper basic rod is connected by a horizontal and longitudinal horizontal balance rod and a diagonal rod, so that the entire disc buckle frame forms a stable frame structure, and the lower disc buckle frame support device jointly supports the upper disc buckle frame, in this case, the damage of individual support devices will not affect the use of the entire disc buckle frame, but in order to ensure construction safety and eliminate safety hazards, the bearing capacity of the support rod assembly 7 can be increased by increasing the width and / or thickness, and this can also effectively extend the service life of the adaptive disc buckle frame support device.
