[0002] In the fields of stone processing, construction and decoration engineering, the fixing and clamping of stone is an important task.

Secondly, the clamping strength and stability of some one-handed stone clamps are insufficient, and the stone cannot be effectively fixed, which easily causes the stone to slip or be damaged. In addition, the cost of such clamps is high, which is not conducive to promotion and application. Utility Model Content

DETAILED DESCRIPTION

[0025] The following embodiments are described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following embodiments do not represent all implementations consistent with the present application. They are only examples of systems and methods consistent with some aspects of the present application as detailed in the claims.

[0026] Although one-handed stone clamps can clamp and fix stones with one hand, there are still many problems in actual use. First, the structural design of some one-handed stone clamps is not reasonable, which makes the operation inconvenient and cannot meet the needs of fast clamping and fixing, resulting in low work efficiency. Secondly, the clamping force and stability of some one-handed stone clamps are insufficient, and the stone cannot be effectively fixed, which easily causes the stone to slip or be damaged. In addition, the cost of such clamps is high, which is not conducive to promotion and application.

[0027] In order to solve the problem of low working efficiency of a one-handed stone clamp, the present application embodiment provides a one-handed stone clamp, see Figure 1 , Figure 1 The schematic diagram of the one-handed stone clamp provided in the present application includes: a handle 11, a force transmission rod 12, a main plate 21 and an auxiliary plate 23; wherein the main plate 21 and the auxiliary plate 23 are arranged between two force transmission rods 12, and the auxiliary plate 23 is arranged at the bottom of the main plate 21. Since the stone 22 is heavy, in order to improve the strength of the clamp, the handle 11, the main plate 21, the force transmission rod 12 and the auxiliary plate 23 can all be made of metal, such as ordinary carbon steel.

[0028] The force transmission rod 12 includes an arc portion 121 and a straight portion 122. The arc portion 121 is a circular arc. One end of the arc portion 121 is connected to the straight portion 122. In order to facilitate connection with the main splint 21 and the auxiliary splint 23, in some embodiments, the cross-sections of the arc portion 121 and the straight portion 122 may be rectangular. The two ends of the handle 11 are detachably connected to one end of the arc portion 121 of the force transmission rod 12 away from the straight portion 122. The handle 11 may be a round rod structure or a long rectangular plate, which is convenient for installation and gripping. In some embodiments, if the length of the clamped stone 22 is fixed, the handle 11 may also be fixed to the arc portions 121 of the two force transmission rods 12 by welding. The handle 11 is used for holding and applying force, and the arcuate portion 121 of the force transmission rod 12 is used for transmitting the force applied by the handle 11 to the main plate 21. By setting the force transmission portion of the force transmission rod 12 as an arcuate structure, a better force transmission effect can be provided, so that the force can be more effectively transmitted to the main plate 21.

[0029] See also Figure 2 , Figure 2The main plate structure schematic diagram provided in the present application, the main plate 21 includes a first surface 211, a second surface 212 and a third surface 213 connected in sequence, the first surface 211 is parallel to the third surface 213, the second surface 212 is perpendicular to the first surface 211 and the third surface 213 respectively, and the height of the first surface 211 is less than the height of the third surface 213. That is, the cross section of the main plate 21 composed of the first surface 211, the second surface 212 and the third surface 213 can be a U-shaped structure, and the heights of the two sides of the U are not equal. The side of the straight portion 122 is provided with a first connecting rod 13, and the two ends of the first surface 211 are hinged to the straight portion 122 through the first connecting rod 13. A through hole may be provided on the side of the straight portion 122, and connecting screw holes may be provided at both ends of the first surface 211, respectively. The first connecting rod 13 is threadedly connected to the connecting screw holes. A gap may be provided between the two ends of the first surface 211 and the two force transmission rods 12, respectively. For example, the gap may be 1 mm, so that the main plate 21 can rotate around the first connecting rod 13 as the axis, so that the first surface 211 of the main plate 21 is hinged to the straight portion 122 of the force transmission rod 12.

[0030] A second connecting rod 14 is also provided on the side of the straight portion 122, and the two ends of the auxiliary splint 23 are detachably connected to the straight portion 122 through the second connecting rod 14, for example, they can be fixed by threaded connection. It can be understood that the main splint 21 is provided at one end of the straight portion 122 close to the arcuate portion 121, and the auxiliary splint 23 is provided at one end of the straight portion 122 away from the arcuate portion 121. The auxiliary splint 23 can be a rectangular plate, and the length of the auxiliary splint 23 can be set to be greater than the length of the first surface 211. Exemplarily, the length of the auxiliary splint 23 can be equal to the length of the first surface 211 plus the above-mentioned gap, so that the two ends of the auxiliary splint 23 can be respectively fitted with the side of the force transmission rod 12, and fixed between the two force transmission rods 12 by the second connecting rod 14. Since the auxiliary clamping plate 23 is fixed between the two force transmission rods 12 to play an auxiliary clamping role, in the embodiment of the present application, there is no restriction on the width of the auxiliary clamping plate 23. For example, the width of the auxiliary clamping plate 23 can be set equal to the height of the first surface 211, and the second connecting rod 14 can be set in the center.

[0031] It can be understood that the first surface 211 , the second surface 212 and the third surface 213 of the main plate 21 form a groove, and the groove faces the side of the main plate 21 away from the arc-shaped portion 121 , and the stone 22 is disposed in the groove. When it is necessary to clamp the stone 22, one end of the stone 22 is placed in the groove of the main splint 21, and the handle 11 is held. Since the first surface 211 of the main splint 21 is hinged to the force transmitting rod 12, and the height of the first surface 211 is less than the height of the third surface 213, under the action of gravity, the third surface 213 is tightened in the direction close to the auxiliary splint 23, and the main splint 21 generates a downward oblique force. Since the auxiliary splint 23 is fixed to the bottom of the main splint 21, the handle 11 is lifted, and the auxiliary splint 23 can limit the stone 22 below the main splint 21, thereby providing a force in the opposite direction of the clamping force of the main splint 21, so that the stone 22 is clamped, and under the influence of the gravity of the stone 22, the clamping force between the third surface 213 of the main splint 21 and the auxiliary splint 23 reaches the maximum value.

[0032] See again Figure 1 See also Figure 3 , Figure 1 The thickness of the stone 22 clamped therein is close to the distance between the first surface 211 and the third surface 213, and is thick stone. Figure 3 The thickness of the stone 22 clamped therein is much different from the distance between the first surface 211 and the third surface 213, and the stone is thin. Figure 3 The state of the auxiliary clamp 23 and the main clamp 21 when the stone 22 is clamped can be more intuitively reflected in the figure. The stone clamp provided by the embodiment of the present application can not only clamp stones 22 of different thicknesses, but also can clamp the stone 22 by lifting the handle 11 with one hand without other operations, which is convenient and fast, can improve the work efficiency of clamping the stone by the clamp, and solve the problem of low work efficiency of the one-hand stone clamp.

[0033] In some embodiments, connection holes may be provided at both ends of the handle 11, and fixing screw holes may be provided on the bottom surface of the arc-shaped portion 121, so that the handle 11 can be detachably connected to the arc-shaped portion 121 through the connection holes and the fixing screw holes, for example, the connection and fixing can be performed by bolts. The connection holes may be elongated holes, and by providing the connection holes as elongated holes, the distance between the two force transmission rods 12 may be adjusted.

[0034] It should also be noted that the arc of the arc portion 121 is a minor arc, that is, the arc of the arc portion 121 is an arc smaller than a semicircle, and the angle between the straight portion 122 and the line connecting the two ends of the arc portion 121 is less than or equal to 90°. The line connecting the two ends of the arc portion 121 is the chord of the arc of the arc portion 121. By setting the angle between the straight portion 122 and the line connecting the two ends of the arc portion 121 to be less than or equal to 90°, the force of holding the handle 11 can be reduced, so that the operator can lift the stone 22 with less effort. At the same time, the clamping force of the auxiliary clamping plate 23 and the main clamping plate 21 can be increased, and the reliability of clamping can be increased. The arc portion 121 and the straight portion 122 can be integrally formed. By integrally forming the arc portion 121 and the straight portion 122 to manufacture the force transmission rod 12, the strength of the force transmission rod 12 can be improved, and the probability of cracking or breaking of the force transmission rod 12 during long-term use can be reduced.

[0035] In some embodiments, the distance between the bottom surface of the auxiliary clamping plate 23 and the second surface 212 can be set to be greater than or equal to one third of the height of the stone 22 to further increase the stability and reliability of the clamping, so that the stone 22 is reliably fixed and the probability of the stone 22 slipping or being damaged is reduced.

[0036] A plurality of limiting holes 123 are provided on the side of the straight portion 122, and the two ends of the auxiliary clamping plate 23 are detachably connected to one of the limiting holes 123. Connecting screw holes can also be provided at the two ends of the auxiliary clamping plate 23, so that the auxiliary clamping plate 23 is fixed to the straight portion 122 between the two force transmission rods 12 by the second connecting rod 14 through the connecting screw holes and the limiting holes 123. It should be noted that the auxiliary clamping plate 23 can be selected to be connected to which limiting hole 123 according to the height of the stone 22, and it is only necessary to meet that the distance between the bottom surface of the auxiliary clamping plate 23 and the second surface 212 is greater than or equal to one third of the height of the stone 22. By providing a plurality of limiting holes 123, it is only necessary to change the position where the auxiliary clamping plate 23 is fixed without replacing the force transmission rod 12, so that stones 22 of different heights can be clamped, and the versatility of the force transmission rod 12 can be improved.

[0037] See again Figure 2 , the two ends of the second surface 212 are respectively provided with a clearance groove 214. In some embodiments, the clearance groove 214 may be a rectangular structure, and a mounting hole is provided on one side of the clearance groove 214. The mounting hole is provided on one side of the clearance groove 214 near the end of the second surface 212. By providing mounting holes at both ends of the second surface 212, when the length of the stone 22 is long, in order to make the clamping more reliable, the two main splints 21 can be connected, and then the handle 11 and the auxiliary splint 23 of matching length can be replaced to clamp the stone 22. Since the weight of the stone 22 carried by one hand is limited, the number of spliced ​​main splints 21 is limited.

[0038] In some embodiments, the clamp further includes a buffer pad, which is disposed on a side of the third surface 213 close to the stone 22. The buffer pad may be made of rubber and has elasticity, which can, on the one hand, make the stone 22 more firmly clamped between the auxiliary clamping plate 23 and the main clamping plate 21, and on the other hand, increase the friction between the stone 22 and the third surface 213, further making the stone 22 reliably clamped between the auxiliary clamping plate 23 and the main clamping plate 21. In the embodiment of the present application, the position of the buffer pad is only described in words, and the buffer pad is not shown in the drawings.

[0039] It can be seen from the above technical scheme that the embodiment of the present application provides a one-handed stone clamp, including: a handle 11, a force transmission rod 12, a main splint 21 and an auxiliary splint 23; the main splint 21 and the auxiliary splint 23 are arranged between the two force transmission rods 12, and the auxiliary splint 23 is arranged at the bottom of the main splint 21. The force transmission rod 12 includes an arc portion 121 and a straight portion 122, the main splint 21 is hinged to the top of the straight portion 122, and the auxiliary splint 23 is fixedly connected to the bottom of the straight portion 122. The main splint 21 includes a first surface 211, a second surface 212 and a third surface 213 connected in sequence, and the first surface 211, the second surface 212 and the third surface 213 form a groove. When it is necessary to clamp the stone 22, one end of the stone 22 is placed in the groove of the main splint 21, the handle 11 is held, and the third surface 213 is tightened in the direction close to the auxiliary splint 23, and then the handle 11 is lifted to clamp the stone 22. Through the coordinated action of the handle 11, the force transmission rod 12, the main clamping plate 21 and the auxiliary clamping plate 23, the clamp can achieve the effect of single-handed operation, fast clamping and fixing of stones. The clamp provided by the present application can adapt to stones 22 of different sizes, is convenient and fast, can improve the working efficiency of clamping stones by the clamp, and solve the problem of low working efficiency of single-handed stone clamps.

[0040] Similar parts between the embodiments provided in this application can be referenced to each other. The specific implementation methods provided above are only a few examples under the general concept of this application and do not constitute a limitation on the protection scope of this application. For those skilled in the art, any other implementation methods expanded based on the scheme of this application without creative work belong to the protection scope of this application.
