Abstract
Combined type spoon is used in a kind of experiment, by bottom key bit, in the middle part of the shank of the key, key bit, key bit top, transverse axis, upper connecting rod, lower connecting rod, lower link, upper connecting rod and room groove form, by arranging bottom key bit, in the middle part of key bit and key bit top, overcoming existing spoon is equipped with too much, can not spoonful multiplex problem, the utility model is novel in design simultaneously, simple structure, production cost is low, is worthy to be popularized.
Description
Technical field
The utility model relates to chemistry and bioscience instrument field, and particularly combined type spoon is used in a kind of experiment.
Background technology
At present, the spoon of conventional use for laboratory is formed, during experiment, very according to needing the spoon choosing suitable dimension to add reducing to medicine primarily of key bit and key shank.But existing spoon specification is too much, can not be spoonful multiplex, is equipped with too much spoon, causes waste.
Summary of the invention
The purpose of this utility model is equipped with too much to overcome existing spoon, can not spoonful multiplex problem, the one experiment combined type spoon provided.
technical scheme:
The utility model by bottom key bit, in the middle part of the shank of the key, key bit, key bit top, transverse axis, upper connecting rod, lower connecting rod, lower link, upper connecting rod and room groove form.Bottom key bit, in the middle part of key bit and key bit upper group be combined as bottomless hemisphere face, with two be parallel to this hemisphere sphere bottom surface at a distance of being two these hemisphere faces of planar interception of this half radius of a ball 1/3rd, near and be 1/3rd these half radiuses of a ball with hemisphere face bottom surface distance apart from this hemisphere face bottom surface in two planes, the spherical crown intercepted is bottom key bit; Make perpendicular to the plane of hemisphere bottom surface the tangent plane that bottom key bit, bottom surface is round with one, be truncated in the middle part of key bit between tangent plane and Hang Liangge cross section, Yuanping City; Apart from the key bit top that is truncated between the cross section and tangent plane of hemisphere 1/3rd radius of a ball; The shank of the key is oval column, and the shank of the key is fixedly connected with bottom key bit, is provided with transverse axis in the middle part of the shank of the key perpendicular to the shank of the key axis, and cut end mutually with tangent plane in the middle part of key bit and be fixedly connected with lower connecting rod, lower connecting rod and lower link are fixedly connected on transverse axis, can rotate around transverse axis; Key bit top and tangent plane cut end mutually and are fixedly connected with upper connecting rod, and upper connecting rod and upper connecting rod are fixedly connected on transverse axis, can rotate around transverse axis; The shank of the key is provided with room groove away from key bit bottom end.
beneficial effect:
The utility model, by arranging bottom key bit, in the middle part of key bit and key bit top, overcomes existing spoon and is equipped with too much, can not spoonful multiplex problem, and the utility model is novel in design simultaneously, and simple structure, production cost is low, is worthy to be popularized.

Fig. 3 is the utility model schematic diagram when not using.
In figure: 1. bottom key bit, 2. the shank of the key, 3. in the middle part of key bit, 4. key bit top, 5. transverse axis, 6. upper connecting rod, 7. lower connecting rod, 8. lower link, 9. go up connecting rod, 10. room groove.
Detailed description of the invention
As shown in Figure 1-Figure 3, the utility model by bottom key bit 1, in the middle part of the shank of the key 2, key bit 3, key bit top 4, transverse axis 5, upper connecting rod 6, lower connecting rod 7, lower link 8, upper connecting rod 9 and room groove 10 form.Bottom key bit 1, in the middle part of key bit 3 and key bit top 4 combine as bottomless hemisphere face, with two be parallel to this hemisphere sphere bottom surface at a distance of being two these hemisphere faces of planar interception of this half radius of a ball 1/3rd, near and be 1/3rd these half radiuses of a ball with hemisphere face bottom surface distance apart from this hemisphere face bottom surface in two planes, the spherical crown intercepted is bottom key bit 1; Make the tangent plane of 1 bottom surface circle bottom key bit with one perpendicular to the plane of hemisphere bottom surface, between tangent plane and Hang Liangge cross section, Yuanping City, to be truncated in the middle part of key bit 3; Apart from the key bit top 4 that is truncated between the cross section and tangent plane of hemisphere 1/3rd radius of a ball; The shank of the key 2 is oval column, the shank of the key 21 to be fixedly connected with bottom key bit, is provided with transverse axis 5 in the middle part of the shank of the key 2 perpendicular to the shank of the key 2 axis, and in the middle part of key bit, 3 cut end mutually with tangent plane and are fixedly connected with lower connecting rod 7, lower connecting rod 7 and lower link 8 are fixedly connected on transverse axis 5, can rotate around transverse axis 5; Key bit top 4 and tangent plane cut end mutually and are fixedly connected with upper connecting rod 6, and upper connecting rod 6 and upper connecting rod 9 are fixedly connected on transverse axis 5, can rotate around transverse axis 5; The shank of the key 2 is provided with room groove 10 away from 1 end bottom key bit.
When using the utility model, 8 and upper connecting rod 9 is connected under only needing to press with hand, axle head in vertical with upper connecting rod 9 for lower connection 8 the shank of the key 2 is placed in room groove 10, because in the middle part of lower connection 8 and lower connecting rod 7 and key bit, 3 are fixedly linked, upper connecting rod 9 and upper connecting rod 6 and key bit top 4 are fixedly linked, and the utility model is its capacity maximum rating; In like manner, if desired reduce capacity, only axle head in vertical for lower link 8 the shank of the key 2 need be placed in room groove 10.
