Abstract
The utility model provides a novel test-tube stand for laboratories. The stand comprises a plurality of base plates arranged through the stack-up vertical rods connected in a supporting manner, wherein a plurality of positioning holes for accommodating and positioning test tubes are uniformly formed in the base plate. The stand is characterized in that a plurality of elastic pieces protruding out of the inner walls of the positioning holes are arranged in the positioning holes; the elastic pieces are connected from head to tail in sequence so as to form elastic washers sharing the same centers with the positioning holes and used for fixing the test tubes. According to the stand, as the elastic washers defined by the elastic pieces protruding out of the inner walls of the positioning holes provides certain suction and clamping force for the test tube walls, the test tubes are sucked and prevented form falling off the test tube stand when the test tube stand is inverted or being turned over, and the aim of the stand is reached.
Description
Technical field
The utility model relates to a kind of rack for test tube, relate in particular to a kind of rack for test tube be inverted or upset in can hold the use for laboratory test tube stand that test tube so that test tube can not depart from.
Background technology
The overwhelming majority only plays an effect of holding positioning test tube for the rack for test tube in the laboratories such as school instruction, scientific research institutions at present, the test tube being placed on rack for test tube can not be clamped, more can not flip upside down, when laboratory technician need to check in low speed automatic turning instrument in vitro the response situation of solution, current rack for test tube does not just reach requirement, therefore, the purpose of this utility model is to provide a kind of novel rack for test tube, make rack for test tube be inverted or upset in can hold test tube so that test tube can not depart from rack for test tube.
Utility model content
In order to solve the deficiency in background technology, the purpose of this utility model is to overcome the defect of background technology, and a kind of use for laboratory test tube stand is provided, and when rack for test tube is inverted or is overturn, test tube can not depart from rack for test tube.
For achieving the above object, the technical solution used in the present invention is: a kind of use for laboratory test tube stand, comprise several base plates that arrange by the stacked support and connection of vertical rod, on described base plate, be equipped with several for holding and locate the locating hole of described test tube, it is characterized in that: in described locating hole, be provided with the shell fragment that several protrude from its inwall, and several shell fragment head and the tail are connected to form the elastic washer for fixing described test tube concentric with described locating hole in turn, it also comprises the base that is positioned at base plate below described in minimum one deck, between described base and base plate also by described vertical rod support and connection, on described base, the position of corresponding described locating hole offers the blind hole identical with locating hole aperture separately, in described blind hole, be provided with pad, the material of described pad is a kind of in rubber or silica gel.
In preferred embodiment of the utility model, further comprise that described locating hole is through-hole structure.
In preferred embodiment of the utility model, further comprise that the aperture of locating hole is incomplete same described in several, and identical described locating hole interval, aperture being arranged on described base plate with row or same column uniformly.
In a preferred embodiment of the present invention, the material that further comprises described shell fragment is a kind of in rubber or silica gel.
In preferred embodiment of the utility model, further comprise between described vertical rod and base plate, base and be and removably connect.
In preferred embodiment of the utility model, further comprise on described base plate and be circumferentially also provided with several columns along it.
Usefulness of the present utility model is: a kind of use for laboratory test tube stand of the present utility model, by the shell fragment that protrudes from locating hole inwall, be enclosed the elastic washer that forms to the certain suction of test tube wall and chucking power, consequently it can not depart from rack for test tube to make rack for test tube when being inverted or overturning, can hold test tube, thereby reaches the purpose of this utility model.
accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of preferred embodiment of the present utility model.
In figure: 2, vertical rod, 4, base plate, 6, locating hole, 8, shell fragment, 10, elastic washer, 12, base, 14, blind hole, 16, pad, 18, column.
The specific embodiment
In order to make those skilled in the art person understand better the utility model scheme, and above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with embodiment and embodiment accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of use for laboratory test tube stand, comprise several base plates 4 that arrange by the stacked support and connection of vertical rod 2, the utility model for convenience, select two base plates 4 to be described, certainly be not limited to two, can be designed to as required three, four or more, on base plate 4, be equipped with several for holding the also locating hole 6 of positioning test tube, in locating hole 6, be provided with several shell fragments that protrudes from its inwall 8, and several shell fragments 8 head and the tail be connected to form in turn with locating hole 6 concentric for the fixing elastic washer 10 of test tube, wherein the material of shell fragment 8 is a kind of in rubber or silica gel, rubber or silica gel have good elasticity and pliability, between elastic washer 10 and test tube, be soft contact, make can not damage test tube in clamping process, the elastic washer 10 of elastic material that protrudes from locating hole 6 inwalls is to suction of test tube and chucking power, consequently it can not depart from rack for test tube to make rack for test tube when being inverted or overturning, can hold test tube, thereby reach the purpose of this utility model.
As a preferred version of the present utility model, locating hole 6 is through-hole structure, otherwise each base plate 4 is not just divided, and positive and negative all can holding test tubes.
As a preferred version of the present utility model, the aperture of several locating holes 6 is incomplete same, and uniform being arranged on base plate 4 with row or same column in locating hole 6 intervals that aperture is identical, aperture difference can accommodating fixedly different size test tube, be particularly suitable for using in the test site that needs different size test tube, saving takes up room.
As a preferred version of the present utility model, rack for test tube also comprises the base 12 that is positioned at minimum one deck base plate 4 belows, between base 12 and base plate 4 also by vertical rod 2 support and connection, the blind hole 14 that the position of corresponding locating hole 6 offers with locating hole 6 apertures are identical and position is corresponding separately on base 12, in blind hole 14, be provided with the pad 16 of rubber or silica gel material, during use, test tube is from the upper end that is inserted into successively, the pad 16 being arranged in blind hole 14 is same to suction of test tube and chucking power, better fixedly test tube, simultaneously, adopt the structure of blind hole to make the bottom of test tube can not touch the hard thing on testing stand or other contact-making surface, so that damage test tube.
