Abstract

The utility model provides a crucible tong which is formed by connecting a pair of tong bodies through a pin shaft, wherein the tong bodies are symmetric in shapes, and therefore a left tong head, a right tong head, a left handle and a right handle are formed. The front ends of the left tong head and the right tong head are provided with clamping parts which are perpendicular to the left tong head and the right tong head, wherein the clamping parts are tightly attached. Rubber rings are fixedly connected on the inner side of the left tong head and on the inner side of the right tong head. The left tong head and the right tong head are respectively provided with a clamping arc matched with the shapes of articles to be clamped. Holding parts of the left handle and the right handle are provided with thermal insulating layers. The crucible tong is simple in structure, convenient to use, capable of being used for taking the articles in a high temperature state, safe and stable.

Description

Crucible tongs

Technical field

The utility model relates to a kind of crucible tongs.

Background technology

Crucible tongs are common tools of productive life, because the crucible of the crucible after the calcination or generation chemical reaction is in the condition of high temperature, need to it be taken off with crucible tongs, in use, be in the crucible under the condition of high temperature, extreme temperatures, the operator need to take off crucible fast.At present on the market the clamping part of crucible tongs is generally with crucible that a face contacts or the line face contacts, impetus crucible certain a bit on or the contact of a certain position, cause the crucible local pressure easily to damage, also may not clamp high temp objects, cause the danger of scald.The operator may wear mitten in use, because the defensive position that puts on one's gloves can be dumb, possible clamping does not live crucible, has greatly increased the danger of scalding.

The utility model content

Problem according to the prior art existence, the utility model provides a kind of crucible tongs, caliper by a pair of shape symmetry is formed by connecting by bearing pin, form left binding clip, right binding clip, left handle and right handles, the front end of described left binding clip and right binding clip has the clamping part vertical with right binding clip with described left binding clip, and described clamping part fits tightly.

The inboard of described left binding clip and right binding clip is fixedly connected with rubber ring.

Described left binding clip and right binding clip have the clamping circular arc that matches with the gripping object shape.

Gripping place of described left handle and right handles has thermal insulation layer.

The utility model is simple in structure, and is easy to use, the object of can taking under the condition of high temperature, and safety and firmness.

Description of drawings

Fig. 1 is top view of the present utility model.

Fig. 2 is side view of the present utility model.

Among the figure: 1. left binding clip; 2. right binding clip; 3. left handle; 4. right handles; 1.1. rubber ring; 1.2. circular arc; 1.3. clamping part; 2.2 thermal insulation layer.

The specific embodiment

For making the technical solution of the utility model and advantage clearer, below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is known complete description:

Crucible tongs as shown in Figure 1 and Figure 2, caliper by a pair of shape symmetry is formed by connecting by bearing pin, form left binding clip 1, right binding clip 2, left handle 3 and right handles 4, the front end of left binding clip 1 and right binding clip 2 has the clamping part 1.3 vertical with described left binding clip 1 and right binding clip 2, and described clamping part 1.3 fits tightly.

Further, as shown in Figure 1, the inboard of left binding clip 1, right binding clip 2 is fixedly connected with rubber ring 1.1, rubber ring 1.1 has elasticity, excessive damage caught object prevents from exerting oneself in clamping process, rubber ring 1.1 also plays the frictional force that increases between crucible tongs and clipped object in addition, makes crucible tongs more firmly clamp object.

Further, as shown in Figure 1: left binding clip 1, right binding clip 2 have the clamping circular arc 1.2 that matches with the gripping object appearance, make crucible tongs can firmly clamp object to be pressed from both sides.

Improve the most technical scheme; as shown in Figure 2; left handle 3 and right handles 4 have thermal insulation layer 2.2 for user's gripping place; this is better to having played protective effect in use; if clamping high temperature object, crucible tongs may reach uniform temperature in moment, owing to having thermal insulation layer 2.2; in use, hold the effect that protection has namely been played at thermal insulation layer 2.2 places.

The utility model provides a kind of crucible tongs simple in structure, and the objects such as crucible of not only can taking easily, and using method simple and flexible have played safe effect.

The above; it only is the better specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or change according to the technical solution of the utility model and utility model design thereof, all should be encompassed within the protection domain of the present utility model.
