And the height of the heating body is regulated in a non-manual regulation mode, so that the lifting is stable.
To the fixed form of test tube, adopt test tube clamp 301 centre gripping, can use to consolidate the not unidimensional test tube, and only carry out the removal of horizontal direction to the test tube, can avoid the breakage problem that misoperation caused.
The supporting net 201 of the device can be taken out, and the test tube clamp 301 can be close to or far away from the heating area of the heating body through the control of the telescopic arm 401, so that the device can heat a beaker or a test tube independently according to the experiment requirement, and the experiment equipment is saved.
The front side wall of the protective cover 101 is made of transparent glass material, so that the height of the heating body can be observed conveniently, and the adjustment is facilitated.
With respect to the specific actuation of the telescopic arm 401, the telescopic arm 401 comprises a rod 402, a first adjustment bladder 403 and a return spring 405.
The rod body 402 horizontally and movably penetrates through the side wall of the protective cover 101, the inner end of the rod body is fixed with the test tube clamp 301, the outer end of the rod body is fixed with a stop block, and the part of the rod body 402 extending out of the protective cover 101 is arranged in a shell fixed with the protective cover 101. First regulation gasbag 403 is arranged in the casing, an external trachea that has first valve 404 that has on the air cock of first regulation gasbag 403, the trachea can be connected with the air pump, can extrude the body of rod 402 and move to the inboard after first regulation gasbag 403 inflates the inflation. The return spring 405 is sleeved on the rod 402 between the stopper and the sidewall of the shield 101 and is compressed as the rod 402 moves horizontally inward.
When the flexible arm 401 of needs inwards extends, first valve 404 is opened, and the air pump is aerifyd to first regulation gasbag 403 in for extrude the body of rod 402 inwards to remove after first regulation gasbag 403 expands, make the test tube be located the heating body top, reset spring 405 is compressed this moment, aerifys the back that finishes, and first valve 404 is closed and is carried out the pressurize to first regulation gasbag 403, can remove the air pump. After the experiment is finished, the first valve 404 is opened to deflate and contract the first adjusting air bag 403, and the return spring 405 is reset to drive the rod 402 to move outwards. The telescopic form is simple, the rod body 402 only moves in the horizontal direction, and the falling phenomenon cannot occur.
As for a specific driving form of the lifting portion, as shown in fig. 3, the lifting portion includes a lower fixing sleeve 502, an upper movable sleeve 503, and a second regulating airbag 504. The lower fixing sleeve 502 is vertically arranged, the top of the lower fixing sleeve 502 is open, the upper movable sleeve 503 is sleeved with the lower fixing sleeve 502, the top of the upper movable sleeve 503 is sealed, and the protection seat 501 is fixed at the top of the upper movable sleeve 503. The second adjusting air bag 504 is arranged in the inner cavity of the lifting part, and an air nozzle of the second adjusting air bag 504 is externally connected with an air pipe with a second valve 505, and the air pipe can be connected with an air pump. After the second adjusting airbag 504 is inflated, the upper movable sleeve 503 can be pushed to move upwards along the lower fixed sleeve 502, the corresponding parts of the lower fixed sleeve 502 and the lower fixed sleeve 502 are provided with long holes for air pipes to pass through, and the movement of the upper movable sleeve 503 is not influenced by the air pipes. The maximum travel of the upper movable sleeve 503 does not disengage the lower fixed sleeve 502.
When the upper movable sleeve 503 needs to move upwards, the second valve 505 is opened, the air pump inflates air into the second adjusting air bag 504, so that the upper movable sleeve 503 is pressed upwards after the second adjusting air bag 504 expands, the upper movable sleeve 503 moves upwards along the lower fixed sleeve 502, after the heating body moves to a proper position, the air pump stops inflating, the second valve 505 is closed to maintain the pressure of the second adjusting air bag 504, and the air pump is removed. After the belt test is finished, the second valve 505 is opened, the second adjusting air bag 504 is deflated and contracted, and the heating body moves downwards.
The air pump in the device is preferably manual, so that the cost is low, the operation is stable, and the participation enthusiasm of experimenters is increased.
In order to enable the heating body to be located at the central part of the protective cover 101, the temperature of a space formed by the protective cover 101 is uniform, and the heating effect is improved, therefore, the lower end of the lifting part is fixed on a base 601, the outer edge of the base 601 protrudes out of the lifting part, and the inner cavity of the protective cover 101 is matched with the outer edge of the base 601. Through the cooperation of base 601 and protection casing 101, still be favorable to the stability of protection casing 101, be difficult for empting.
Further, the base 601 is a polygonal structure, and after the base 601 is matched with the protection cover 101, the protection cover 101 cannot rotate, so that the position between the heating part of the beaker and the heating body is fixed in the experimental process.
When the base 601 is in a circular structure, in order to prevent the protection cover 101 from rotating, the relative position between the test tube and the heating body is changed, as shown in fig. 4, a slot 602 in the shape of "L" is formed in the side wall of the base 601, an insertion block 104 is fixed at the bottom inside the protection cover 101, and the insertion block 104 can enter from the vertical part of the slot 602 and enter into the horizontal part of the slot 602 along with the rotation of the protection cover 101.
The above is only the preferred embodiment of the present invention, and any person can make some simple modifications, deformations and equivalent replacements according to the present invention, all fall into the protection scope of the present invention.
