Abstract

The utility model relates to a disposable plastic locking clamp, which comprises an upper clamping body, and a lower clamping body, wherein, the upper clamping body and the lower clamping body are connected into integration through an elastic ring, the contacting surface of the inner side of the integration is provided with locking teeth in intermeshing engagement, and the connections of each clamping bodies are respectively provided with a longitudinal locking device and a latitudinal limited device. The utility model has the advantages of simple structure, and convenient operation. After the utility model is locked, if a destructive breakdown is not acted on the utility model, a clamping position can not be opened and optionally changed, so the locking is firm and reliable.

Description

Disposable plastic locking folder

The utility model relates to a kind of geometrical clamp, particularly a kind of disposable plastic locking folder that is used for the clamping article.

Often use some anchor clamps to come the clamping article in daily life.Existing anchor clamps mainly contain spiral rod type brandreth folder, spring plastic processing frame, medical hemostatic folder etc.These anchor clamps are used in corresponding place according to actual instructions for use.But in some places, often need use the anchor clamps locking articles, and not allow random changing position in case lock rear plate as industries such as medical treatment.Existing above-mentioned anchor clamps locking rear plate can arbitrarily be shifted one's position, and can't satisfy the requirement that position, locking back no longer changes.

The purpose of this utility model provides a kind of disposable plastic locking folder, and it is simple in structure, uses is easy to operate, and the locking back is damaged without destructiveness, can't open or arbitrarily changes the clamping position, and locking firmly, reliably.

The purpose of this utility model is achieved in that this device comprises upper and lower clamp, the upper and lower clamp that wherein utilizes elastic ring to link into an integrated entity, its inboard contact-making surface has intermeshing locking teeth, and each clamp bound fraction has vertical locking device and cross spacing device respectively.

Because the utility model adopts elastic ring to connect upper and lower clamp, so can make the open original state of Qi Baote, compares with existing anchor clamps, and is simple in structure, and easy to operate during the clamping article.Because of its contact-making surface has intermeshing locking teeth, there are vertical locking device and cross spacing device in the joint portion, thus its be behind the lock-out state combination very firmly, reliable, damage without destructiveness, can't open, can not arbitrarily change the clamping position, can reach the instructions for use of latched position fully.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a kind of concrete structure schematic diagram of the utility model.

Fig. 2 is the vertical view of Fig. 1.

Fig. 3 is that the A of Fig. 1 is to partial view.

Fig. 4 is that the B of Fig. 1 is to partial view.

Root a tree name Fig. 1-4 describes concrete structure of the present utility model in detail.This device adopts plastic material to make upper clamp 4, lower clamp 6, and the two utilizes elastic ring 5 to link into an integrated entity, and makes it to be in all the time open original state.Inboard contact-making surface at upper and lower clamp all is processed with intermeshing locking teeth 3, locks therebetween article not play, non-displacement by intermeshing tooth.There are vertical locking device and cross spacing device in the joint portion of upper and lower clamp, can determine concrete structure according to actual instructions for use.In the present embodiment, vertically locking device adopts dovetail type tensioning hook 1 and barb groove 8, and cooperatively interacting links together vertically locks; The cross spacing device adopts pin 2 and the retaining groove 7 cooperatively interact, can not produce lateral displacement after making upper and lower clamp locking.The contact-making surface of pin 2 and retaining groove 7 can be the plane, also can be the inclined-plane.This cross spacing device also can be located at connecing between edged surface of upper and lower clamp, and a tooth middle part is provided with horizontal convex tendon therein, in the another side tooth transverse concave groove is set, and convex tendon and groove are cooperatively interacted, and reaches spacing purpose.Vertically also available other version of locking device makes it back can't the unlatching without the destructiveness damage of locking and gets final product.This device clamping is convenient, firm.

Claims

1, a kind of disposable plastic locking folder comprises upper and lower clamp, it is characterized in that the upper and lower clamp that utilizes elastic ring to link into an integrated entity, and its inboard contact-making surface has intermeshing locking teeth, and each clamp bound fraction has vertical locking device and cross spacing device respectively.
