Abstract
A weight clamp for physics teaching includes two elastic clamp plates, wherein one ends of the two elastic clamp plates are connected, and the other ends thereof are both provided with clamping devices; each clamping device includes a connecting part and a fixed part; one ends of the connecting parts are connected with the elastic clamping plates, and the other ends thereof are connected with the inward-concave fixed parts; a fixed groove is formed in the fixed part; a plurality of No.1 non-skid threads are uniformly arranged in the fixed groove; a hand pressing groove is formed on the elastic clamp plate adjacent to the clamping device; and a plurality of No.2 non-skid threads are uniformly arranged in the hand pressing groove. The weight clamp for the physics teaching has a strong clamping force and an excellent anti-skidding effect.
Description
Technical field
The utility model relates to a kind of physical teaching aid, relates in particular to a kind of counterweight clamp that is used for physics teaching, specifically is applicable to the difficulty that reduces the counterweight of taking, and improves the efficient of Physical Experiment.
Background technology
At present, when carrying out physics experiment teaching, usually need use balance and counterweight; When using counterweight, need counterweight be picked up from box with on the pallet that is put into balance with tweezers, but because counterweight is heavier; And smooth surface; Common tweezers are usually landing when taking counterweight, not only fragile counterweight, and can reduce teaching efficiency.
The Chinese patent Granted publication number is CN201350604Y; Granted publication day is that the utility model patent on November 25th, 2009 discloses the vertical counterweight tweezers that a kind of physics teaching experiment is used; It is processed by plastics or metal; Its feature is to be respectively equipped with the leg hook that bends inwards in the lower end of two tweezers legs, and the leg hook is vertical with the tweezers leg, on the leg hook, also is provided with arc folder mouth.Though utility model can be laborsaving when taking counterweight, because it can only be through an arc folder mouthful clamping counterweight, contact area is very narrow, chucking power very a little less than, in use, counterweight still comes off easily.
Summary of the invention
The purpose of the utility model is to overcome more weak defective and the problem of chucking power that exists in the prior art, provides a kind of chucking power the stronger counterweight clamp that is used for physics teaching.
For realizing above purpose, the technical solution of the utility model is: a kind of counterweight clamp that is used for physics teaching, and this counterweight clamp comprises two Elastic clamping plates, and an end of said two Elastic clamping plates interconnects, and the other end is provided with a clamping device; Said clamping device comprises connecting portion and fixed part, and an end of connecting portion is connected with Elastic clamping plate, and the other end is connected with fixed part, and fixed part is the inner concave shape structure.
The set inside of said fixed part has holddown groove, evenly is provided with many non-skid threads in this holddown groove.
The manufactured materials of said fixed part is elastic metal sheet or elastoplast plate.
The position of nearly clamping device is provided with and presses the hand groove on the said Elastic clamping plate, and this is by evenly being provided with many No. two non-skid threads in the hand groove.
Compared with prior art, the beneficial effect of the utility model is:
1, because an a kind of end that is used for two Elastic clamping plates of counterweight clamp of physics teaching of the utility model interconnects, and the other end is provided with a clamping device, and this clamping device comprises connecting portion and fixed part, an end of connecting portion is connected with Elastic clamping plate; The other end is connected with fixed part, and fixed part is the inner concave shape structure, during use; Directly contact with counterweight through fixed part,, thereby can obtain preferably with the head of counterweight and cooperate because fixed part is the inner concave shape structure; Simultaneously, the length of fixed part is longer, thereby major part that can clamping counterweight head; Thereby obtain stronger grip, security is higher, difficult drop-off.Therefore the chucking power of the utility model is stronger.
2, because being provided with, a kind of counterweight clamp position of nearly clamping device on Elastic clamping plate that is used for physics teaching of the utility model presses the hand groove; This is by evenly being provided with many No. two non-skid threads in the hand groove; During use; Be difficult for to slide with can guaranteeing to point through finger, thereby be convenient to point the bigger chucking power of transmission by contacting of hand groove, and then the enhancing grip.Therefore the chucking power of the utility model is stronger.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: Elastic clamping plate 1, clamping device 2, connecting portion 21, fixed part 22, holddown groove 23, non-skid thread 3, press hand groove 4, No. two non-skid threads 5.
The specific embodiment
Below in conjunction with the description of drawings and the specific embodiment the utility model is done further detailed explanation.
Referring to Fig. 1, a kind of counterweight clamp that is used for physics teaching, this counterweight clamp comprises two Elastic clamping plates 1, and an end of said two Elastic clamping plates 1 interconnects, and the other end is provided with a clamping device 2; One of special feature of the utility model is: said clamping device 2 comprises connecting portion 21 and fixed part 22, and an end of connecting portion 21 is connected with Elastic clamping plate 1, and the other end is connected with fixed part 22, and fixed part 22 is the inner concave shape structure.This design is convenient to improve the chucking power of the utility model.
The set inside of preferred immobilization portion 22 has holddown groove 23, evenly is provided with many non-skid threads 3 in this holddown groove 23.This design is convenient to anti-skidding, to improve grip.
The manufactured materials of preferred immobilization portion 22 is elastic metal sheet or elastoplast plate.This design is convenient to transmit chucking power.
The position of nearly clamping device 2 is provided with and presses hand groove 4 on the preferred elastomeric clamping plate 1, and this is by evenly being provided with many No. two non-skid threads 5 in the hand groove 4.This design is convenient to anti-skidding, to improve grip.
During use, finger is pinned by hand groove 4 power is passed to Elastic clamping plate 1, by Elastic clamping plate 1 power is passed to the fixed part 22 in the clamping device 2 again, then by the firm head of clamping counterweight of fixed part 22, thus the fixing counterweight of taking.
Therefore the utility model not only chucking power is stronger, and skidproof effect is better.
The above is merely the preferred embodiments of the utility model; The protection domain of the utility model does not exceed with above-mentioned embodiment; As long as the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or changed, all should include in the protection domain of putting down in writing in claims.
