Description
Technical field
The utility model relates to student appliance technical field, especially a kind of student experimenting thermometer fixed frame.
Background technique
Student is frequently necessary to thermometer measure fluid temperature when doing physically or chemically experiment, it is common practice to student
Hand-held thermometer, which is protruded into liquid, to be measured, and not only student is easy tired but also is not easy to student's reading, and notification number is
By setting lid and fixed link come fixed thermometer, this is solved the utility model of CN207050878U to a certain extent
State problem, but be limited by the structure, however it remains itself lack crystallized ability, hold in the jiggly situation of heating platform
It is also easy to produce the problem of tilt slide causes thermometer to contact beaker inner wall.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical disadvantages to provide a kind of student experimenting thermometer fixed frame,
The relative position for realizing that single unit system and beaker are kept fixed is pressed from both sides using arc, is realized that thermometer is fixed using fixed device, is adopted
The adjusting that thermometer height and horizontal position are realized with telescopic rod A, telescopic rod B, threaded rod and positioning sleeve, avoids thermometer from touching
Beaker inner wall.
The utility model solves the technical solution that technical problem uses are as follows: a kind of student experimenting thermometer fixed frame, packet
Parantheses clevis, telescopic rod A, telescopic rod B and fixed device, the setting of arc folder is convenient for device to be fixed on beaker outer wall, institute
It states arc folder upper end and is connected with telescopic rod A, regulating device height is convenient in the setting of telescopic rod A, and the upper end telescopic rod A is connected with screw thread
Bar, is socketed with telescopic rod B on threaded rod, and the setting of telescopic rod B avoids convenient for adjusting thermometer the distance between to telescopic rod A
Thermometer touches beaker inner wall, is bolted with hand nutting on threaded rod above telescopic rod B, the setting of hand nutting is convenient for adjusting
The angle of telescopic rod B, and then the angle of thermometer is controlled, telescopic rod A is outside up-thin-low-thick two-period form telescopic rod and its upper section
Side is socketed with spring A, and the both ends spring A are respectively and fixedly connected with the lower section of telescopic rod B and telescopic rod A, and the setting of spring A can stretch adjusting
Buffer function is played during bar A length, is provided with adjusting bolt on telescopic rod A and telescopic rod B, convenient for adjusting telescopic rod
The length of A and telescopic rod B, telescopic rod B right end are connected with fixed device, and fixed device is by fixed plate, spongy layer and spring B group
At fixed plate is symmetrically set with two and the opposite one end of two fixed plates is provided with the groove of semi-cylindrical, setting in groove
There is spongy layer, fixed thermometer is convenient in the setting of fixed plate, and the setting of spongy layer is convenient for protection thermometer, two fixed plates opposite one
Spring groove there are four being symmetrical arranged is held, is connected with spring B in opposite two spring eye, convenient for quickly release and fixed thermometer.
Beneficial effect possessed by the utility model is: the structure design of the utility model is reasonable, is realized using arc folder whole
The relative position that body device and beaker are kept fixed realizes that thermometer is fixed using fixed device, using telescopic rod A, telescopic rod
B, threaded rod and positioning sleeve realize the adjusting of thermometer height and horizontal position, and thermometer is avoided to touch beaker inner wall.
Detailed description of the invention
Attached drawing 1 is the structural schematic diagram of the utility model.
Attached drawing 2 is the top view that device is fixed in the utility model.
Attached drawing 3 is the top view of arc folder in the utility model.
Specific embodiment
1~attached drawing 3 is described below the utility model with reference to the accompanying drawing.
As shown in FIG. 1 to 3, the utility model includes arc folder 1, telescopic rod A3, telescopic rod B8 and fixed device 5, arc
Convenient for device to be fixed on beaker outer wall, the arc presss from both sides 1 upper end and is connected with telescopic rod A3, telescopic rod A3 for the setting of clevis 1
Setting be convenient for regulating device height, the upper end telescopic rod A3 is connected with threaded rod 4, telescopic rod B8 is socketed on threaded rod 4, stretches
The setting of bar B8 avoids thermometer touching beaker inner wall convenient for adjusting thermometer the distance between to telescopic rod A3, on threaded rod 4
Hand nutting 6 is bolted with above telescopic rod B8, the setting of hand nutting 6 controls convenient for adjusting the angle of telescopic rod B8
The angle of thermometer, telescopic rod A3 are that up-thin-low-thick two-period form telescopic rod and its upper section outer sheath are connected to spring A2, spring A2
Both ends are respectively and fixedly connected with the lower section of telescopic rod B8 and telescopic rod A3, and the setting of spring A2 can be during adjusting telescopic rod A3 length
Buffer function is played, adjusting bolt 7 is provided on telescopic rod A3 and telescopic rod B8, convenient for adjusting telescopic rod A3 and telescopic rod B8
Length, telescopic rod B8 right end is connected with fixed device 5, and fixed device 5 is by fixed plate 5-3, spongy layer 5-5 and spring B 5-1 group
Two are symmetrically set at, fixed plate 5-3 and two opposite one end fixed plate 5-3 are provided with the groove 5-4 of semi-cylindrical, it is recessed
