Abstract
The utility model discloses a tweezers for centre gripping rock core, including centre gripping arm (2), its characterized in that: the clamping arm (2) is provided with an arc-shaped clamping end surface (4); the arc-shaped clamping end face (4) is used for increasing the contact area with the rock core; the problem of current ordinary tweezers slippage easily in the rock core centre gripping process for the experiment is solved.
Description
Technical Field
The utility model relates to a clamping tool, specifically a tweezers of centre gripping rock core is exclusively used in.
Background
In the rock core displacement experiment, the experimenter often uses ordinary tweezers to centre gripping rock core, but ordinary tweezers lack the obstacle, and the rock core can rock about in the tweezers, and easy slippage brings the inconvenience for the use.
Disclosure of Invention
In view of this, the utility model provides a tweezers for centre gripping rock core solves the problem of current ordinary tweezers slippage easily at the rock core centre gripping in-process for the experiment.
In order to achieve the above purpose, the forceps for holding a rock core comprises a holding arm, and is characterized in that:
the clamping arm is provided with an arc-shaped clamping end surface;
and the arc-shaped clamping end face is used for increasing the contact area with the rock core.
Preferably, the arc-shaped clamping end surface is provided with an anti-skid structure or an anti-skid component;
the anti-skidding structure or the anti-skidding component is used for increasing the friction force of the arc-shaped clamping end face in contact with the rock core.
Preferably, the anti-slip structure is an anti-slip tooth.
Preferably, the non-slip member is a rubber mat.
Preferably, a groove is arranged on the outer side wall surface of the clamping arm;
the groove is used for preventing the hand from slipping off the clamping arm.
Preferably, the groove is a rectangular groove.
Preferably, the groove has an anti-slip structure or an anti-slip part therein.
Preferably, the anti-slip structure is an anti-slip tooth;
the anti-slip part is a rubber mat.
Preferably, the upper end of the clamping arm is provided with a hanging ring.
The utility model discloses following beneficial effect has:
the utility model discloses a tweezers for centre gripping rock core designs traditional centre gripping terminal surface into the arc, on the one hand with the surface of rock core more laminate, on the other hand has increased the area of contact between the two; in addition, an anti-skid structure is designed on the clamping end face, so that the contact friction force between the clamping end face and the rock core is increased; therefore, the tweezers can effectively avoid the core slipping; simultaneously, still set up the groove structure who prevents the hand slippage on the centre gripping arm, increased the stability of operation.
Drawings
The above and other objects, features and advantages of the present invention will become more apparent from the following description of the embodiments of the present invention with reference to the accompanying drawings, in which:
fig. 1 is a schematic structural diagram of tweezers for holding a rock core according to an embodiment of the present invention.
Detailed Description
The present invention will be described below based on examples, but it should be noted that the present invention is not limited to these examples. In the following detailed description of the present invention, certain specific details are set forth in detail. However, for parts not described in detail, those skilled in the art can fully understand the present invention.
Furthermore, those skilled in the art will appreciate that the drawings are provided for purposes of illustrating the objects, features, and advantages of the invention and are not necessarily drawn to scale.
Also, unless the context clearly requires otherwise, throughout the description and the claims, the words "comprise", "comprising", and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is, the meaning of "includes but is not limited to".
Fig. 1 is a schematic structural diagram of tweezers for holding a rock core according to an embodiment of the present invention. As shown in figure 1, the tweezers for clamping the rock core comprise a clamping arm 2, wherein the clamping arm 2 is provided with an arc-shaped clamping end face 4, and the arc-shaped clamping end face 4 can increase the contact area between the tweezers and the rock core, so that the stability in the clamping process is improved, and the rock core is prevented from slipping off from the tweezers.
The arc-shaped clamping end face 4 is provided with an anti-slip structure, and the anti-slip structure is used for increasing the friction force of the arc-shaped clamping end face 4 contacting with the rock core. In fig. 1, the anti-slip structure is an anti-slip tooth 5. Of course, the anti-slip structure may be a rubber pad.
In fig. 1, a groove is provided on the outer side wall of the clamp arm 2 for preventing the hand from slipping off the clamp arm 2. The groove can be a rectangular groove 3, and anti-skid structures or anti-skid components such as anti-skid teeth or rubber pads and the like can also be arranged in the groove.
In fig. 1, the upper end of the gripping arm 2 has a suspension loop 1.
During the use, hold between the fingers thumb and forefinger in rectangular channel 3 of two centre gripping arms 2, two arc centre gripping terminal surfaces 4 of two centre gripping arms 2 front ends press from both sides respectively on the surface of rock core, and arc centre gripping terminal surface 4 is laminated more with the contact surface of rock core on the one hand, and on the other hand arc centre gripping terminal surface 4 is bigger with the area of contact of rock core, so, guarantees that the rock core does not follow the exposed core slippage of arc centre gripping terminal surface 4.
In addition, the arc-shaped clamping end face 4 is provided with the anti-skidding teeth 5, the friction force of the anti-skidding teeth 5 and the rock core can be increased when the anti-skidding teeth are in contact with the rock core, the rock core is further prevented from slipping, and the stability of the operation process is ensured.
After the use, the hanging ring 1 of the tweezers is hung at a fixed position in a laboratory, so that the tools can be conveniently stored and kept.
The above-mentioned embodiments are merely embodiments for expressing the invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several changes, substitutions, modifications, etc. can be made without departing from the spirit of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
