Description
Technical field
The utility model relates to chemical engineering experiment equipment, is specially a kind of test tube clamp.
Background technology
In the industry of pharmaceutical production, often need to test.The instrument that test tube often uses when being experiment, often uses test tube clamp when test tube of taking, and especially when heating, needs, with test tube clamp, line operate is lived in test tube clamping.Existing test tube clamp generally comprises two jig arm be hinged, and is provided with and makes two jig arm remain the spring of clamp position between two jig arm.Because the clip slot shape in jig arm immobilizes, when clamping less test tube, the deflection of spring is less, and the elastic force produced is less, thus makes the chucking power of jig arm to test tube less, the test tube that clamping that can not be very steady is less; When clamping larger test tube, the deflection of spring is comparatively large, makes the chucking power of jig arm to test tube excessive, easily crushes test tube.Thus, existing test tube clamp can only clamp a kind of test tube of diameter, when needing to clamp different test tubes, needing to carry out replacing test tube clamp, thus making troubles to user.
Utility model content
The purpose of this utility model is to provide a kind of test tube clamp, can only adapt to a kind of test tube of caliber to solve test tube clamp in prior art, uses inconvenient problem.
To achieve these goals, a kind of test tube clamp that the utility model provides, comprises the first jig arm and the second jig arm, the first jig arm and the second jig arm hinged, be connected with torsion spring between the first jig arm and the second jig arm, the second jig arm is provided with clip slot; It is characterized in that: also comprise governor motion, described governor motion comprises the clamping plate of arc, adjusting rod and gag lever post, described clamping plate and clip slot are oppositely arranged, one end and the clamping plate of described adjusting rod are rotationally connected, adjusting rod is threaded with the first jig arm, gag lever post and adjusting rod be arranged in parallel, and one end of gag lever post is connected with clamping plate, and gag lever post and the first jig arm are slidably connected.
Arrange clamping plate, match with the clip slot in the second jig arm during use holding test tubes.Adjusting rod is set, for regulating the distance between clamping plate and the first jig arm.Adjusting rod and clamping plate are rotationally connected, and adjusting rod can be relatively rotated with clamping plate, thus clamping plate can not be driven when adjusting rod is rotated to rotate.Adjusting rod is provided with thread segment, and adjusting rod is threaded with the first jig arm, is realized the axially-movable of adjusting rod by rotary regulating lever.The gag lever post parallel with adjusting rod being set, rotating for preventing clamping plate.Gag lever post and the first jig arm are slidably connected, and gag lever post can be moved with clamping plate.
Operation principle and the beneficial effect of this programme are: adjusting rod adopts with the first jig arm and is threaded, fix the first jig arm, rotary regulating lever, make adjusting rod along its axially-movable, thus drive clamping plate to move, due to being flexibly connected with the first jig arm of gag lever post, being connected with Boards wall simultaneously, clamping plate can only be moved along the axis direction of adjusting rod.When the test tube that clamping caliber is less, rotary regulating lever makes clamping plate away from the first jig arm, and when the first jig arm is opened in the second jig arm, the distance between clamping plate and clip slot is less, is suitable for clamping the less test tube of caliber; When the test tube that clamping caliber is larger, rotary regulating lever makes clamping plate near the first jig arm, and when the first jig arm and the second jig arm are opened, the distance between clamping plate and clip slot is comparatively large, thus is suitable for clamping the larger test tube of caliber.Described in front, by arranging governor motion on test tube clamp, thus make test tube clamp can adapt to clamp the test tube of different tube diameters.
Further, described clamping plate are provided with rubber layer near the face of clip slot.When clamping plate coordinate holding test tubes with clip slot, rubber layer can deform and surface area is increased under stress, thus the contact surface of clamping plate and test tube is increased, and is conducive to the pressure that reduction test tube bears.
Further, described rubber layer is provided with thermal insulation layer.When heating test-tube, be conducive to preventing the heat of test tube to test tube clamp transmission.
Further, described adjusting rod is provided with regulating handle away from one end of clamping plate.Convenient operation person rotary regulating lever.
Further, the end of described first jig arm is provided with link.Facilitate test tube clamp to hang to place, convenient operation person take.
Further, the length of described first jig arm is two times of the second jig arm.Make the weight saving of whole test tube clamp, be conducive to operating personnel's gravity that arm bears in use and reduce.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of a kind of test tube clamp of the utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
In figure: the first jig arm 1, second jig arm 2, gag lever post 3, adjusting rod 4, regulating handle 5, clamping plate 6, rubber layer 7, thermal insulation layer 8, torsion spring 9, clip slot 10, link 11.
A kind of test tube clamp as shown in Figure 1, the length comprising the first jig arm 1 and the second jig arm 2, first jig arm 1 is two times of the second jig arm 2.First jig arm 1 flushes with the upper end of the second jig arm 2, and bottom and first jig arm 1 of the second jig arm 2 are hinged.Be connected with torsion spring 9 between first jig arm 1 and the second jig arm 2, the middle part of the second jig arm 2 is provided with clip slot 10, and in the first jig arm 1, the position relative with clip slot 10 is provided with groove.The groove of the first jig arm 1 is provided with governor motion, and governor motion comprises the clamping plate 6 of arc, and clamping plate 6 and clip slot 10 are oppositely arranged, and the right flank of clamping plate 6 is provided with rubber layer 7, and the right flank of rubber layer 7 is provided with thermal insulation layer 8.The left side of clamping plate 6 is provided with adjusting rod 4, the middle part of the left surface of clamping plate 6 and the right-hand member ball-joint of adjusting rod 4.Adjusting rod 4 is provided with thread segment, and adjusting rod 4 is threaded with the first jig arm 1.The left end of adjusting rod 4 is provided with regulating handle 5.The upper and lower both sides of adjusting rod 4 are equipped with a gag lever post 3 in parallel, and gag lever post 3 and the first jig arm 1 are slidably connected, and the right-hand member of gag lever post 3 is threaded with clamping plate 6.The lower end of the first jig arm 1 is provided with link 11.
During use, when the test tube that clamping caliber is less, rotary regulating lever 4 makes clamping plate 6 away from the first jig arm 1, and when the first jig arm 1 and the second jig arm 2 are opened, the distance between clamping plate 6 and clip slot 10 is less, is suitable for clamping the less test tube of caliber; When the test tube that clamping caliber is larger, rotary regulating lever 4 makes clamping plate 6 near the first jig arm 1, and when the first jig arm 1 and the second jig arm 2 are opened, the distance between clamping plate 6 and clip slot 10 is comparatively large, thus is suitable for clamping the larger test tube of caliber.Thus need not change test tube clamp and just can clamp different test tubes, handled easily librarian use.
Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite not departing from the utility model structure; some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
