fig. 2 is the local enlarger of first end of cap opener body of the utility model.

Detailed Description

The present invention is further described in detail below with reference to the drawings so that those skilled in the art can implement the invention with reference to the description.

It will be understood that terms such as "having," "including," and "comprising," as used herein, do not preclude the presence or addition of one or more other elements or groups thereof.

As shown in fig. 1-2, the utility model provides a cap opener for many rows of PCR pipes, include:

the first end of the cap opener body 1 is set to be a cylindrical structure, the second end 11 of the cap opener body 1 is set to be a round table-shaped structure, the first end 10 and the second end of the cap opener body 1 are respectively provided with a first cavity 12 and a second cavity 13, notches 14 are symmetrically arranged at the opening of the first cavity 12, and the notches 14 and the end face of the first cavity 12 form an included angle of 20-30 degrees.

In the above scheme, through second end 11 of uncapping ware body 1 sets up to round platform column structure, makes its external diameter be less than the external diameter of cylinder structure, thereby make the both ends of uncapping ware body 1, one end is thicker one end thinner, so that when uncapping single centrifuging tube, the different volumes of adaptation are the lid of the centrifuging tube of different lid footpath sizes promptly, through setting up cylinder structure end and being the breach 14 of contained angle with first cavity 12 terminal surface, thereby form the pointed end of 2 slopes, be convenient for be used for opening of lid on the multiple gang PCR pipe, wherein, the method that uncapping ware opened lid on single centrifuging tube and a plurality of gang PCR pipe respectively does:

1. opening of lid on single centrifuging tube, to the size of centrifuge tube lid footpath, select the suitable terminal surface of uncapping ware body 1, overlap first cavity 12 or second cavity 13 on the centrifuging tube lid, make 80% terminal surface of centrifuging tube lid arrange first cavity 12 or second cavity 13 in, at this moment, the open end of lid supports the inner wall of first cavity 12 or second cavity 13, the stress point as being pried up in proper order, the outside of first cavity 12 or second cavity 13 offsets with the top of the relative terminal surface of stress point and lid, thereby form the fulcrum of a lever, rotate to the fulcrum direction through uncapping ware body 1, thereby pry the lid open.

2. For opening the cover body of the multiple-row PCR tube, taking 8-row PCR tubes as an example: choose first end 10 of uncapping ware body 1 for use promptly cylindric structure end, insert two inserted positions on the left side or the right side of 8 ally oneself with row PCR pipes simultaneously with the both sides clamp end of 14 departments of breach, the left side is pried, and the right side is pried again, can open one set of 8 ally oneself with row PCR pipes.

Under the circumstances of the material of the comprehensive consideration lid itself and processing demand, under the circumstances that need not set up the stuck point through first cavity 12 or second cavity 13 inner face, can realize the atress and support, reduced the processing degree of difficulty of product, easily popularize and implement in batches, just the uncapping device has generated actual sample to satisfy operation requirement in using. The small and exquisite simple of cap opener overall structure, and accomodate the convenience, not only can be used for opening of single centrifuging tube lid, can be used to opening of many antithetical couplet row PCR pipe lid simultaneously, application scope is wider.

In a preferred embodiment, the inner diameter of the first cavity 12 is set to be 13-15mm, and the inner diameter of the second cavity 13 is set to be 9-11 mm.

In the above scheme, the inner diameter of the first cavity 12 is set to be 13-15mm, and the inner diameter of the first cavity 12 is taken to be 14mm so as to fit a 1.5/2ml tube cover. The inner diameter of the second cavity 13 is set to be 9-11mm, and the inner diameter of the first cavity 12 is 10mm to be matched with the cap of the 0.5/0.2ml tube.

In a preferable scheme, the height of the cap opener body 1 is set to be 85-100 mm.

In the above scheme, the lid opener body 1 is convenient to carry and store under the condition of utilizing the hand to bear force.

In a preferred embodiment, the wall thickness of the first cavity 12 and the second cavity 13 is set to be 1.3-1.6 mm.

In the above scheme, the arrangement of the wall thickness is beneficial to ensuring the covering surface and stress of the first cavity 12 or the second cavity 13 to the cover body when in use.

In a preferable scheme, the notch 14 is an arc-shaped notch 14, and the distance between the upper side and the lower side of the notch 14 is set to be 2-4 mm.

In the scheme, the arc-shaped notch 14 is favorable for inserting the clamping ends and reducing the sharpness of the contact point, and the 2-4mm distance between the upper side and the lower side of the notch 14 is more favorable for inserting the clamping ends at two sides of the notch 14 and meets the stress requirement.

In a preferred scheme, the length of the gap 14 accounts for 2/3-3/4 of the outer diameter of the first end of the cap opener body 1.

In the above scheme, when the two side clamping ends of the notch 14 are inserted into the multiple rows of PCR tubes, the other end of the notch 14 abuts against the cover body to serve as a fulcrum, and the length of the notch 14 is set, so that the prying action is more labor-saving.

In a preferable scheme, the outer side of the middle of the cap opener body 1 and the outer side of the first cavity 12 are both provided with an annular groove 15.

In the above scheme, through setting up annular groove 15, the frictional force when doing benefit to the handheld cap opener of increase prevents that the finger from perspiring and skidding, the opening of the lid of being convenient for.

While the embodiments of the invention have been described above, it is not intended to be limited to the details shown, or described, but rather to cover all modifications, which would come within the scope of the appended claims, and all changes which come within the meaning and range of equivalency of the art are therefore intended to be embraced therein.
