Description

Technical Field

[0001] The utility model relates to the technical field of concrete testing equipment, in particular to a concrete test block clamping device. Background Art

[0002] A search revealed prior art patent number CN107310936A, which provides the following technical solution: a clamping device comprising: a connecting block with a movable hole on one side; a gripping rod fixed to the connecting block; a fixed splint fixed to the bottom of the connecting block; and a movable splint with a connecting rod fixed to one side of the movable splint, the connecting rod being pivotally connected to the movable hole of the connecting block via a rotating shaft and rotatable within the movable hole. A gravity block is fixed to the connecting rod near the movable splint; the side of the fixed splint facing the movable splint is provided with a relief pattern, and the side of the movable splint facing the fixed splint is also provided with a relief pattern to enhance friction and ensure stable clamping.

[0003] It can be seen from this that the above scheme is to use the movable splint to rotate on the fixed block so that the movable splint moves toward the fixed splint to achieve clamping of the concrete test block. Although the clamping task can be achieved, its clamping force is unreliable. In particular, it relies entirely on the gravity of the movable splint and the counterweight block to achieve the clamping operation during the clamping process. However, first of all, the concrete test block is heavy and is prone to slipping during the lifting process. Secondly, it is necessary to maintain a stable moving speed and no shaking should occur, otherwise it will cause the concrete test block to fall. Utility Model Content

[0004] The purpose of the utility model is to provide a novel concrete test block clamping device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new concrete specimen clamping device, comprising a support member, one end of the support member is connected to a first clamping plate axis pin, and the other end of the support member is connected to a second clamping plate axis pin; a pull rod is also provided in the middle of the support member, and the pull rod is connected to a connecting seat after passing through the support member; one side of the connecting seat is connected to a first transmission rod axis pin, and the other side of the connecting seat is connected to a second transmission rod axis pin; the end of the first transmission rod away from the connecting seat is connected to the first clamping plate axis pin, and the end of the second transmission rod away from the connecting seat is connected to the second clamping plate axis pin.

[0006] As a preferred technical solution of the present invention: the pull rod is adaptively connected to the threaded hole provided in the connecting seat through the threaded portion provided thereon.

[0007] As a preferred technical solution of the present invention: a spring is further provided between the connecting seat and the supporting member; wherein one end of the spring abuts against the supporting member, and the other end of the spring abuts against the connecting seat.

[0008] As a preferred technical solution of the present invention: a support platform is further provided on one end of the connecting seat facing the spring, and a limiting hole is further provided on one side of the supporting member facing the spring.

[0009] As a preferred technical solution of the present invention: both the first clamping plate and the second clamping plate are provided with rubber pads, and the rubber pads are movably mounted on the first clamping plate and the second clamping plate.

[0010] As a preferred technical solution of the present invention: a grip ring is further provided at one end of the pull rod away from the support member.

[0011] By adopting the above technical solution, the beneficial effects of the present invention are as follows: 1. When the connecting base moves upward, the power of the pull rod is transmitted to the first clamping plate and the second clamping plate through the first transmission rod and the second transmission rod, respectively, so that the first clamping plate and the second clamping plate move toward each other, thereby achieving the device to clamp the concrete test block. Based on this, the device can quickly clamp the concrete test block by pulling the pull rod upward, thereby improving the device's clamping efficiency for the concrete test block.

[0012] 2. As the pull rod is lifted, the clamping force of the first and second clamping plates on the concrete test block can be effectively increased, thereby more reliably clamping the concrete test block to prevent the concrete test block from falling during movement. Conversely, the concrete test block can be released by loosening the pull rod. BRIEF DESCRIPTION OF THE DRAWINGS

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limitations on the present invention. In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation on the present invention.

[0020] See also Figure 1-5 , the utility model provides an embodiment: a new concrete test block clamping device, including a support member 1, one end of the support member 1 is axially pinned to a first clamping plate 2, and the other end of the support member 1 is axially pinned to a second clamping plate 3; a pull rod 5 is also provided in the middle of the support member 1, and the pull rod 5 is connected to a connecting seat 7 after passing through the support member 1; one side of the connecting seat 7 is axially pinned to a first transmission rod 8, and the other side of the connecting seat 7 is axially pinned to a second transmission rod 10; the end of the first transmission rod 8 away from the connecting seat 7 is axially pinned to the first clamping plate 2, and the end of the second transmission rod 10 away from the connecting seat 7 is axially pinned to the second clamping plate 3.

[0021] To sum up, as the pull rod 5 is lifted, the clamping force of the first clamping plate 2 and the second clamping plate 3 on the concrete test block 4 can be effectively increased, so that the concrete test block 4 can be clamped more reliably to prevent the concrete test block 4 from falling during movement. Conversely, the concrete test block 4 can be released by loosening the pull rod.

[0022] In addition, when the connecting base 7 moves upward, the power of the pull rod 5 is transmitted to the first clamping plate 2 and the second clamping plate 3 through the first transmission rod 8 and the second transmission rod 10, respectively, so that the first clamping plate 2 and the second clamping plate 3 move toward each other, thereby achieving the device clamping the concrete test block 4. Based on this, the device can quickly clamp the concrete test block by pulling the pull rod 5 upward, thereby improving the device's clamping efficiency for the concrete test block.

[0023] Based on this, compared with the utility model patent previously applied for by our company (patent number: 2023223639921), this device can reliably clamp the concrete test block 4 when used, and the clamping method is simpler and more convenient.

[0024] Among them, the elastic force value of spring 9 can only prompt the pull rod 5 to move downward when there is no external force on the pull rod 5. The main purpose of setting spring 9 is to automatically extend during the downward movement of the pull rod 5 to assist the two clamping plates to unfold. Therefore, the structure of spring 9 is only an auxiliary structure. During the clamping process, it is locked by the connecting seat 7, so the structure of spring 9 is also stable. Its working principle when used is as follows: first, after the pull rod 5 is stretched, the spring 9 is subjected to force. At this time, the upward movement of the pull rod 5 is used to fully realize the clamping of the two clamping plates on the test block. Only when the external force on the pull rod 5 disappears can the spring 9 be reset. Therefore, after the pull rod 5 is subjected to force, the structure of spring 9 is stable in a compressed state, so it will not cause the test block to fall.

[0025] Furthermore, since the pull rod 5 is adapted to be connected to the threaded hole 71 provided in the connecting seat 7 through the threaded portion 51, after the first clamping plate 2 and the second clamping plate 3 are clamped on the concrete test block 4, the position of the first clamping plate 2 and the second clamping plate 3 can be locked by twisting the pull rod 5 to prevent the first clamping plate 2 and the second clamping plate 3 from falling off due to loosening.

[0026] On the basis of the above scheme, a spring 9 is further provided between the connecting seat 7 and the support member 1; wherein, one end of the spring 9 abuts against the support member 1, and the other end of the spring 9 abuts against the connecting seat 7. Therefore, when the pull rod 5 moves upward, the spring 9 is compressed. Conversely, when the external force of the pull rod 5 disappears, the spring 9 is reset. In this process, the reset of the spring 9 can be used to cause the first splint 2 and the second splint 3 to move away from each other, so as to realize the expansion of the first splint 2 and the second splint 3.

[0027] Furthermore, since the end of the connecting seat 7 facing the spring 9 is also provided with a support platform 70, and the side of the support member 1 facing the spring 9 is also provided with a limiting hole 11, the two ends of the spring 9 are reliably restricted to ensure the stable expansion of the first splint 2 and the second splint 3.

[0028] Furthermore, since rubber pads 6 are provided on both the first plywood 2 and the second plywood 3, and the rubber pads 6 are movably installed on the first plywood 2 and the second plywood 3, specifically, bolts are passed through the two plywoods and connected to the rubber pads 6, therefore, in addition to enhancing the friction between the two plywoods and the concrete test block 4, it also facilitates the installation and replacement of the rubber pads 6.

[0029] In addition, in order to facilitate the user to hold the pull rod 5 securely, a grip ring 50 is provided at the end of the pull rod 5 away from the support member 1. At the same time, the outside of the grip ring 50 can also be wrapped with a silicone pad, which makes it easier for the user to hold it tightly and can also prevent the grip ring 50 from slipping during the gripping process.

[0030] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
