[0031] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.
[0032] Reference Figure 1 and Figure 2 As shown, a convenient standard concrete specimen clamping device according to an embodiment of the utility model comprises: a first rod 100 and a second rod 200, wherein the first rod 100 comprises a first gripping rod 110, a first clamping rod 120, and a first connecting rod 130 connecting the first gripping rod 110 and the first clamping rod 120, the first clamping rod 120 is provided with a first suction cup 121, and an end of the first gripping rod 110 away from the first connecting rod 130 is connected to a first rotating portion 111; the second rod 200 comprises a second gripping rod 210, a second clamping rod 220, and a second connecting rod 230 connecting the second gripping rod 210 and the second clamping rod 220. 30. The second gripping rod 210 is spaced apart from the first gripping rod 110. The second connecting rod 230 is provided with a second rotating portion 211, which is rotatably connected to the first rotating portion 111. The second clamping rod 220 is provided with a second suction cup 221, which is arranged opposite to the first suction cup 121. The second rod member 200 is configured such that when the second gripping rod 210 moves around the second rotating portion 211 toward the first gripping rod 110, the second clamping rod 220 moves toward the first clamping rod 120, so that the first suction cup 121 and the second suction cup 221 clamp the object to be clamped, so that the user can clamp the specimen with one hand, which is more convenient to use.
[0033] It is worth understanding that, when in use, the first suction cup 121 and the second suction cup 221 are placed on two opposite sides of the concrete specimen respectively, and by holding the second holding rod 210 and the first holding rod 110, and holding the second holding rod 210 with force, the second rotating portion 211 of the second holding rod 210 rotates around the first rotating portion 111 to drive the second suction cup 221 to move toward the first suction cup 121. The user can hold the first holding rod 110 and the second holding rod 210 with one hand at the same time, and can directly lift the concrete specimen with one hand, which is more convenient to use; the clamping device absorbs the concrete component through the first suction cup 121 and the second suction cup 221. When the first suction cup 121 and the second suction cup 221 are close to the side wall of the concrete specimen, they will be tightly absorbed to the concrete specimen due to the pressure difference, so as to reduce the pressure required to be applied by the user, and the clamping device can achieve a labor-saving effect.
[0034] Reference Figure 1 and Figure 2 As shown, in some specific embodiments of the present invention, the second suction cup 221 is rotatably connected to the second clamping rod 220 , and the rotation axis of the second suction cup 221 is in the same direction as the rotation axis of the second rotating portion 211 .
[0035] It should be noted that when the second suction cup 221 is adsorbed on the side wall of the concrete specimen, if the adsorption surface of the second suction cup 221 is at a certain angle to the side wall of the concrete specimen, the adsorption effect of the second suction cup 221 will be affected, and the safety of use will be reduced. Specifically, the first rod 100 is fixedly arranged, so that the first suction cup 121 is fixedly arranged, and the first suction cup 121 only needs to ensure that the adsorption surface is perpendicular to the ground to fully fit the side wall of the concrete specimen. The second rod 200 can rotate relative to the first rod 100 to drive the second suction cup 221 to approach or move away from the first suction cup 121. During the rotation of the second rod 200, it will undoubtedly cause the adsorption surface of the second suction cup 221 to rotate at a certain angle, thereby reducing the adsorption effect of the second suction cup 221.
[0036] Therefore, in this embodiment, the second suction cup 221 is rotatably connected to the second clamping member, and can rotate in the same direction as the second rotating portion 211. When the second rod 200 rotates a certain angle through the second rotating portion 211, the second suction cup 221 can be connected to the rotating position of the second clamping member by rotation, and the position of the adsorption surface of the second suction cup 221 can be adjusted, so that the adsorption surface of the second suction cup 221 is always parallel to the side wall of the concrete specimen, so that the adsorption surface of the second suction cup 221 is fully in contact with the side wall of the concrete specimen, and the adsorption effect is maintained.
[0037] Reference Figure 1 and Figure 2As shown, in some specific embodiments of the present invention, the convenient standard concrete specimen clamping device also includes: an angle adjustment component, which connects the second clamping rod 220 and the second suction cup 221 to adjust the angle of the first suction cup 121 relative to the second suction cup 221.
[0038] It is worth to understand that the angle of the second suction cup 221 is adjusted by the angle adjustment member 300 to achieve the rotational connection between the second suction cup 221 and the first clamping rod 120 .
[0039] In this embodiment, the angle adjustment assembly includes a fixed plate 310 connected to the first clamping rod 120 and a rotating plate 320 rotatably connected to the fixed plate 310, and the rotating plate 320 is connected to the second suction cup 221. Specifically, a rotating shaft hole is provided on a side of the fixed plate 310 facing the rotating plate 320, and a rotating shaft rod is provided on a side of the rotating plate 320 facing the fixed plate 310, and the rotating shaft rod is rotatably provided in the rotating shaft hole and can rotate around the rotating shaft hole.
[0040] Reference Figure 1 and Figure 2 As shown, in some specific embodiments of the present invention, the fixed plate 310 and the rotating plate 320 are spaced apart, and a reset assembly 330 is provided between the fixed plate 310 and the rotating plate 320 , and the reset assembly 330 is used to reset the second suction cup 221 relative to the first suction cup 121 .
[0041] It should be noted that when the convenient standard concrete specimen clamping device clamps concrete specimens of different sizes, the amplitude of each rotation of the second rod 200 is not consistent, so that the position of the rotating plate 320 after each rotation is uncertain. Sometimes, the position of the rotating plate 320 needs to be actively corrected for normal use.
[0042] Therefore, through the reset assembly 330 between the fixed plate 310 and the rotating plate 320, the rotating plate 320 can be actively reset to the initial position, thereby realizing automatic reset of the rotating plate 320 without manual correction, which is more convenient to use.
[0043] Reference Figure 1 and Figure 2 As shown, in some specific embodiments of the present invention, the reset assembly 330 includes a first elastic member 331 and a second elastic member 332. The interval space between the rotating plate 320 and the fixed plate 310 is divided into a first space 333 and a second space 334 with the rotation axis of the rotating plate 320 as the boundary. The first elastic member 331 is arranged in the first space 333, and the second elastic member 332 is arranged in the second space 334.
[0044] It is worth understanding that the first elastic member 331 and the second elastic member 332 are used together to limit the rotating plate 320, so that after the rotating plate 320 rotates a certain angle under the action of external force, the first elastic member 331 and the second elastic member 332 both store a certain elastic potential energy. When the external force is removed, the first elastic member 331 and the second elastic member 332 can automatically return to the initial position under the action of the stored elastic potential energy, which is more convenient to use.
[0045] Reference Figure 1 and Figure 2 As shown, in some specific embodiments of the present invention, the second rod member 200 includes at least two second clamping rods 220, each second clamping rod 220 is provided with a second suction cup 221, all second clamping rods 220 are connected to the second connecting rod 230, and the second clamping rods 220 are arranged at intervals along the rotation axis of the second rotating part 211.
[0046] In this embodiment, the number of the second clamping rods 220 is two, and each second clamping rod 220 is provided with a second suction cup 221. The concrete specimen is fixed by a plurality of second suction cups 221 to improve the clamping effect of the convenient standard concrete specimen clamping device. The number of the second clamping rods 220 may also be three or more, and the second clamping rods 220 may also be provided with two or more second suction cups 221.
[0047] In addition, the number of the first clamping rods 120 is also two, and they are opposite to the second clamping rods 220 one by one. When clamping, the concrete specimen is subjected to more uniform force to avoid local force and damage to the specimen, and the clamping effect is better.
[0048] Reference Figure 1 and Figure 2 As shown, in some specific embodiments of the present invention, the outer circumference of the first gripping rod 110 is covered with a first gripping sleeve 112 , and the outer circumference of the second gripping rod 210 is covered with a second gripping sleeve 212 .
[0049] It is worth understanding that the first gripping sleeve 112 and the second gripping sleeve 212 provide protection, so that the user can directly use the portable standard concrete specimen clamping device without gloves, which is more convenient to use. In addition, the outer peripheral surface of the first gripping sleeve 112 can be provided with an anti-slip layer, and the outer peripheral surface of the second gripping sleeve 212 can also be provided with an anti-slip layer to further improve the gripping effect.
[0050] Reference Figure 1 and Figure 2 As shown, in some specific embodiments of the present invention, one end of the first holding rod 110 away from the first connecting rod 130 is connected to the first rotating rod 140 , and one end of the first rotating rod 140 away from the first connecting rod 130 is provided with a first rotating portion 111 .
[0051] It is worth understanding that the first gripping rod 110 is rotatably connected to the second connecting rod 230 via the first rotating rod 140, so that the distance between the first gripping rod 110 and the second gripping rod 210 is more controllable, making it easier to set the distance between the first gripping rod 110 and the second gripping rod 210 to be appropriate for the user to hold.
[0052] Reference Figure 1 and Figure 2 As shown, in some specific embodiments of the present invention, the second rod 200 includes a third connecting rod 240, which connects the second holding rod 210 and the same end of the second connecting rod 230, and a portion of the second connecting rod 230 is parallel to the second holding rod 210 and spaced apart.
[0053] It is worth understanding that the second gripping rod 210 and the second connecting rod 230 are separated by the third connecting rod 240, and a portion of the second connecting rod 230 is parallel to the second gripping rod 210, so that the distance from the second gripping rod 210 to the second rotating portion 211 is increased, and the second gripping rod 210 only needs a small amount of force to achieve the same rotational torque as before, thereby saving effort and facilitating use by users.
[0054] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
