Description
Technical Field
[0001] The utility model relates to the field of ground support and / or counterweight, and in particular to a plane counterweight plate. Background Art
[0002] At present, temporary paving of the ground often uses large steel plates to lay directly, which makes it too heavy and requires large equipment to construct, which is not suitable for some special occasions or personal use needs; the applicant initially wanted to open grooves or convex strips on the side of the plate along its length direction, and realize the connection and assembly between the plates through concave-convex matching (which can be understood as dovetail matching), while avoiding the problem of individual plates warping up, but the problem that follows is that this assembly method requires the plates to slide along their plane direction to achieve docking, such as in the field-shaped assembly (divided into There are four quadrants, and one-to-one sliding fit assembly can be achieved between the first and second quadrants, and between the second and third quadrants). However, due to its structure, the last plate (the fourth quadrant needs to be compatible with the first and third quadrants at the same time) can only slide in one of the sides and cannot be compatible with the other side (that is, after sliding and docking with the side of the first quadrant, it cannot be sliding and docking with the side of the third quadrant). At the same time, in some occasions where the space in the length and width directions is limited, it may be impossible to provide space for the plate before assembly, so there are substantial problems in assembly. Utility Model Content
[0003] Based on the above problems, the utility model aims to provide a flat counterweight plate which is easy to assemble, suitable for improving the pressure-bearing effect and flatness of the ground, and at the same time provides pressure for counterweighting.
[0004] In view of the above problems, the following technical solutions are provided: a flat counterweight plate, comprising a plate body, the plate body being polygonal, the front of the plate body being provided with fan-shaped / semicircular grooves at the positions of the edges of the outer contour thereof, the center of the fan-shaped / semicircular groove being perpendicular to the front of the plate body and being colinear with the edges of the side of the plate body, the fan-shaped / semicircular groove being buckled with the fan-shaped / semicircular groove of another plate body to form a revolving groove; the radius / diameter of the outer groove wall of the fan-shaped / semicircular groove or the revolving groove at the position close to the bottom of the fan-shaped / semicircular groove is smaller than that at the position close to the bottom of the fan-shaped / semicircular groove; The radius / diameter at the top of the fan-shaped / semicircular groove forms a tightening inclined surface; a half stud with a semicircular cross-section is provided at the center of the fan-shaped / semicircular groove, the center of the half stud is concentrically arranged with the center of the fan-shaped / semicircular groove, and the half stud is buckled with the half stud in the fan-shaped / semicircular groove of another plate body to form a whole stud; it also includes a nut, the center of the nut is provided with an internal thread that is threadedly engaged with the whole stud, and the outer side wall of the nut and the bottom surface are provided at the junction with the tightening inclined surface of the fan-shaped / semicircular groove or the rotary groove.
[0005] In the above structure, sector / semicircular grooves and half studs are provided at the positions of the side edges of the plate body. When the plate bodies are spliced, the sector / semicircular grooves form a rotary groove, and the half studs form complete studs. By screwing a nut onto the complete stud, the pressing inclined surface abuts against the outer conical surface. At this time, the force generated by the abutment of the pressing inclined surface against the outer conical surface causes the bottom positions of the sides of the plate body to abut tightly against each other. The tops of the half studs of the two plate bodies tend to separate, but this tendency is restricted by the internal thread, thereby realizing the reliable butt joint between the plate bodies by using this structure. At the same time, the flatness and butt joint rigidity between adjacent plate bodies can be guaranteed. Since the plate bodies do not need to be assembled by side sliding in this splicing method, it is not restricted by the size of the site. Since the plate bodies are made into a split type, the overall weight is reduced, and one person can carry and assemble them. Even if the thickness of the plate body is increased to improve the overall rigidity, its quality can still ensure convenience by reducing the length and width dimensions of the plate body.
[0006] The present utility model is further configured such that the upper end surface of the half stud or the complete stud is lower than or equal to the height of the notch of the sector / semicircular groove or the rotary groove.
[0007] In the above structure, it is avoided that the half stud or the complete stud protrudes outward and affects the flatness of the assembled plate body.
[0008] The present utility model is further configured such that when the outer conical surface abuts against the outer groove wall of the sector / semicircular groove or the rotary groove, the upper end surface of the nut is lower than or equal to the height of the notch of the sector / semicircular groove or the rotary groove.
[0009] In the above structure, it is avoided that the nut protrudes outward and affects the flatness of the assembled plate body.
[0010] The present utility model is further configured such that the upper end surface of the nut is provided with torsion pits uniformly distributed along its circumferential direction.
[0011] In the above structure, the number of torsion pits is preferably an even number, which is used to adapt to a wrench for disassembling and assembling the nut.
[0012] The present utility model is further configured such that the cone half angle of the pressing inclined surface with respect to the central axis of the sector / semicircular groove is 30 degrees - 60 degrees.
[0013] In the above structure, the cone half angle of the pressing inclined surface with respect to the central axis of the sector / semicircular groove is preferably 45 degrees.
[0014] The present utility model is further configured such that the depth of the sector / semicircular groove is 1 / 2 to 2 / 3 of the thickness of the plate body.
[0015] In the above structure, the depth of the sector / semicircular groove is preferably 2 / 3 of the thickness of the plate body, and the thickness of the nut is preferably 1 / 2 of the thickness of the plate body, ensuring that when the nut is flush with or slightly lower than the notch height of the sector / semicircular groove or the rotary groove, there is a pre-tightening gap between the bottom of the nut and the bottom of the sector / semicircular groove, ensuring the reliable abutment of the pressing inclined surface and the outer conical surface.
[0016] The present utility model is further configured such that the plate body is an aluminum alloy plate or a steel plate.
[0017] In the above structure, the plate body can select different materials according to needs. The aluminum alloy plate features lightness, and the steel plate features a weight counterweight effect.
[0018] The present utility model is further configured such that the plate body is quadrilateral or hexagonal; one or more sector / semicircular grooves are provided on the side line of the plate body, and when there are multiple sector / semicircular grooves, they are arranged at intervals along the length direction of the side line.
[0019] In the above structure, the plate body is preferably a regular quadrilateral; at least two sector / semicircular grooves are preferably provided on each side line.
[0020] The present utility model is further configured such that identification marks are provided in pairs at the positions of the side lines of the plate body that face each other.
[0021] In the above structure, since the threads of the half studs need to be butt-jointed when combined into a complete stud, in order to ensure that the starting positions of the helical lines of the unified threads are the same (which can be achieved through combined milling), the identification marks are used to determine the docking direction of the plate body, so as to ensure that the half stud on the left side of the plate body can be combined with the half stud that originally belonged to the left side of another plate body but reaches the right side due to rotation to form a complete stud, and at the same time, the half stud on the upper side of the plate body can be combined with the half stud on the lower side of the plate body to form a complete stud, thereby meeting the splicing of the plate body.
[0022] The present utility model is further configured such that the identification marks are offset from the midpoint of the corresponding side line and are symmetric or mirror-symmetric with respect to the mid-plane between the side lines that face each other.
[0023] In the above structure, it is used to distinguish the orientation of the plate body, avoiding the situation where the helical lines are discontinuous due to the 180-degree rotation of the plate body, resulting in the docking of the half stud on the left side of the present plate body with the half stud that originally belonged to the left side of another plate body but reaches the right side due to rotation.
[0024] The beneficial effects of the present utility model:
[0025] 1. Sector / half-round grooves and half studs are provided at the positions of the edges of the plate body. When the plate bodies are spliced, the sector / half-round grooves form a rotary groove, while the half studs form a complete stud. By screwing a nut onto the complete stud, the pressing inclined surface abuts against the outer conical surface. At this time, the force generated by the abutment of the pressing inclined surface and the outer conical surface causes the bottom positions of the sides of the plate bodies to abut tightly against each other. Although the tops of the half studs of the two plate bodies tend to separate, this trend is restricted by the internal thread. Thus, this structure is used to achieve reliable docking between the plate bodies, and at the same time, the flatness and docking rigidity between adjacent plate bodies can be ensured. Since the plate bodies do not need to be assembled by side sliding in this splicing method, there is no limitation by the size of the site. Since the plate bodies are made in a split form, the overall weight is reduced, and one person can carry and assemble them. Even if the thickness of the plate body is increased to improve the overall rigidity, its quality can still ensure convenience by reducing the length and width dimensions of the plate body.
[0026] 2. It is applicable to surfaces that are not suitable for local large pressure, such as certain large-area wooden board surfaces, and is used for bearing by laying the plate bodies.
[0027] 3. It is required to have weight and a smooth plane - for certain short-term road surfaces, such as grasslands, sandy lands, muddy roads, etc.
[0028] 4. The counterweight is stable and does not slip, and can be used as a counterweight, which is applicable to occasions where counterweight is required but height occupation is not allowed.
[0029] 5. The assembly is simple, and it is applicable to occasions such as families, camping, offices, etc. to adjust the nature of the ground. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following combines the accompanying drawings and embodiments to further describe in detail the specific implementation manners of the present utility model. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model
[0039] Refer to Figures 1 to 7 As Figures 1 to 7 shown, a planar counterweight plate includes a plate body 10. The plate body 10 is polygonal. Sector / semicircular grooves 11 are provided at the positions of the side lines of the outer contour on the front surface of the plate body 10. The center of the sector / semicircular groove 11 is perpendicular to the front surface of the plate body 10 and collinear with the side line of the side surface of the plate body 10. The sector / semicircular groove 11 and the sector / semicircular groove 11 of another plate body 10 are buckled to form a rotary groove 12; the radius / diameter of the outer groove wall of the sector / semicircular groove 11 or the rotary groove 12 at a position close to the bottom of the sector / semicircular groove 11 is smaller than the radius / diameter at a position close to the top of the sector / semicircular groove 11 to form a pressing inclined surface 13; a half stud 14 with a semicircular cross-section is provided at the center of the sector / semicircular groove 11. The center of the half stud 14 is concentric with the center of the sector / semicircular groove 11. The half stud 14 and the half stud 14 in the sector / semicircular groove 11 of another plate body 10 are buckled to form an integral stud 15; it further includes a nut 20. An internal thread 21 that is in threaded engagement with the integral stud 15 is provided at the center of the nut 20. An external conical surface 22 that abuts and fits with the pressing inclined surface 13 of the sector / semicircular groove 11 or the rotary groove 12 is provided at the junction of the outer side wall and the bottom surface of the nut 20
[0040] In the above structure, sector / semicircular grooves 11 and half studs 14 are provided at the positions of the respective side edges of the plate body 10. When the plate bodies 10 are spliced with each other, the sector / semicircular grooves 11 form a rotary groove 12, and the half studs 14 form complete studs 15. By screwing the nut 20 with the complete stud 15, the pressing inclined surface 13 abuts against the outer conical surface 22. At this time, the force generated by the abutment of the pressing inclined surface 13 and the outer conical surface 22 causes the bottom positions of the sides of the plate body 10 to abut against each other tightly. The tops of the half studs 14 of the two plate bodies 10 will show a tendency to separate, but this tendency is restricted by the internal thread 21. Thus, the reliable docking between the plate bodies 10 is realized by using this structure, and at the same time, the flatness and docking rigidity between adjacent plate bodies 10 can be guaranteed; since the plate body 10 does not need to be assembled by side sliding in this splicing method, it is not restricted by the size of the site; since the plate body 10 is made into a split type, the overall weight is reduced, and one person can carry out the handling and assembly. Even if the thickness of the plate body 10 is increased to improve the overall rigidity, its quality can be ensured for convenience by reducing the length and width dimensions of the plate body 10.
[0041] In this embodiment, the upper end surface of the half stud 14 or the complete stud 15 is lower than or equal to the notch height of the sector / semicircular groove 11 or the rotary groove 12.
[0042] In the above structure, the upper end surface of the half stud 14 or the complete stud 15 is flush with the notch height of the sector / semicircular groove 11 or the rotary groove 12, so as to avoid the protrusion of the half stud 14 or the complete stud 15 from affecting the flatness of the assembled plate body 10.
[0043] In this embodiment, when the outer conical surface 22 abuts against the outer groove wall of the sector / semicircular groove 11 or the rotary groove 12, the upper end surface of the nut 20 is lower than or equal to the notch height of the sector / semicircular groove 11 or the rotary groove 12.
[0044] In the above structure, when the outer conical surface 22 abuts against the outer groove wall of the sector / semicircular groove 11 or the rotary groove 12, the upper end surface of the nut 20 is equal to the notch height of the sector / semicircular groove 11 or the rotary groove 12, so as to avoid the protrusion of the nut 20 from affecting the flatness of the assembled plate body 10.
[0045] In this embodiment, the upper end surface of the nut 20 is provided with torsion pits 23 evenly distributed along its circumferential direction.
[0046] In the above structure, the number of the torsion pits 23 is preferably an even number, which is used to adapt to the wrench (solid in the figure) for disassembling and assembling the nut 20.
[0047] In this embodiment, the cone half angle a of the pressing inclined surface 13 relative to the center axis of the sector / semicircular groove 11 is 30 degrees - 60 degrees.
[0048] In the above structure, the cone half angle of the pressing inclined surface 13 relative to the center axis of the sector / semicircular groove 11 is preferably 45 degrees.
[0049] In this embodiment, the depth of the sector / semicircular groove 11 is 1 / 2 to 2 / 3 of the thickness of the plate body 10.
[0050] In the above structure, the depth of the sector / semicircular groove 11 is preferably 2 / 3 of the thickness of the plate body 10, and the thickness of the nut 20 is preferably 1 / 2 of the thickness of the plate body 10. When the nut 20 is level with or slightly lower than the notch height of the sector / semicircular groove 11 or the rotary groove 12, a pre-tightening gap is left between the bottom of the nut 20 and the bottom of the sector / semicircular groove 11 to ensure the reliable contact between the pressing inclined surface 13 and the outer conical surface 22.
[0051] In this embodiment, the plate body 10 is an aluminum alloy plate or a steel plate.
[0052] In the above structure, the plate body 10 can be made of different materials according to needs. Aluminum alloy plates are mainly for lightness, and steel plates are mainly for counterweight effect.
[0053] In this embodiment, the plate body 10 is quadrilateral or hexagonal; one or more sector / semicircular grooves 11 are provided on the side line of the plate body 10, and when there are multiple sector / semicircular grooves 11, they are arranged at intervals along the length direction of the side line.
[0054] In the above structure, the plate body 10 is preferably a regular quadrilateral; at least two sector / semicircular grooves 11 are preferably provided on each side line.
[0055] In this embodiment, identification marks 16 are provided in pairs at positions on the opposite side lines of the plate body 10.
[0056] In the above structure, when the half studs 14 are combined into a complete stud 15, the threads need to be butt-jointed with each other. Therefore, to ensure that the starting positions of the helical lines of the unified threads are the same (which can be achieved by compound milling), the identification marks 16 are used to determine the docking direction of the plate body 10, so as to ensure that the half studs 14 on the left side of the plate body 10 and the half studs 14 on the right side of another plate body 10 that originally belonged to its left side can be combined into a complete stud 15, and at the same time, the half studs 14 on the upper side of the plate body 10 and the half studs 14 on the lower side of the plate body 10 can be combined into a complete stud 15, thus meeting the splicing of the plate body 10.
[0057] In this embodiment, the identification marks 16 are offset from the midpoint of the corresponding side line and are symmetric or mirror-symmetric with respect to the mid-plane between the opposite side lines.
[0058] In the above structure, it is used to distinguish the orientation of the plate body 10 and avoid the situation where the helical lines are not continuous due to the 180-degree rotation of the plate body 10, resulting in the docking of the half studs 14 on the left side of this plate body 10 and the half studs 14 on the right side of another plate body 10 that originally belonged to its left side but reached the right side due to rotation.
[0059] The beneficial effects of the present utility model:
[0060] 1. Sector / semicircular grooves 11 and half studs 14 are provided at the positions of each side edge of the plate body 10. When the plate bodies 10 are spliced together, the sector / semicircular grooves 11 form a rotary groove 12, and the half studs 14 form a complete stud 15. By screwing the nut 20 with the complete stud 15, the pressing inclined surface 13 abuts against the outer conical surface 22. At this time, the force generated by the abutment of the pressing inclined surface 13 and the outer conical surface 22 causes the bottom positions of the sides of the plate body 10 to abut tightly against each other. The tops of the half studs 14 of the two plate bodies 10 will tend to separate, but this tendency is restricted by the internal thread 21. Thus, the reliable butt joint between the plate bodies 10 is realized by using this structure, and at the same time, the flatness and butt joint rigidity between adjacent plate bodies 10 can be guaranteed. Since the plate body 10 does not need to be assembled by side sliding in this splicing method, it is not restricted by the size of the site. Since the plate body 10 is made into a split type, the overall weight is reduced, and one person can carry and assemble it. Even if the thickness of the plate body 10 is increased to improve the overall rigidity, its quality can be ensured for convenience by reducing the length and width dimensions of the plate body 10.
[0061] 2. It is applicable to the surface where local large pressure is not suitable, such as some large-area wooden board surfaces, and is used for bearing by laying the plate body 10.
[0062] 3. It is required to have weight and a smooth plane, such as some short-term road surfaces, such as grasslands, sandy lands, muddy roads, etc.
[0063] 4. The counterweight is stable and does not slide, and can be used as a counterweight, and is applicable to the occasions where counterweight is required but does not occupy height.
[0064] 5. The assembly is simple, and it is applicable to occasions such as families, camping, offices, etc. to adjust the nature of the ground.
[0065] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present invention, several improvements and modifications can be made. These improvements and modifications made under the above assumptions should also be regarded as the protection scope of the present invention.
