DETAILED DESCRIPTION

[0023] The technical scheme of the utility model is further explained below through the drawings and examples.

[0024] In combination Figures 1 to 5 , the utility model provides a kind of portable pharmaceutical experiment measuring cylinder, including outer cylinder 1, the inside of outer cylinder 1 is equipped with placement ring 5, the top of placement ring 5 is equipped with two elastic sheets 7, the inner side of two elastic sheets 7 is equipped with multiple protrusions 8, the inner side of placement ring 5 is equipped with inner cylinder 6, the outer side of elastic sheet 7 is equipped with inner conical surface 4, the inner side of inner conical surface 4 is in contact with the outer side of elastic sheet 7, the top of inner conical surface 4 is equipped with threaded segment 3, the inner wall of outer cylinder 1 is equipped with screw groove, threaded segment 3 is connected with screw groove by screw thread.

[0025] With reference to Figures 1-4 , the top of threaded segment 3 is equipped with cylinder body 2, the top of cylinder body 2 is equipped with handle 9, one end of cylinder body 2 is located in the inside of outer cylinder 1, handle 9 is located in the outside of outer cylinder 1, one end of outer cylinder 1 is fixedly connected with fixing ring 12.

[0026] When carrying, first, the solution needed is measured, then, the solution is poured into the inside of inner cylinder 6, then, inner cylinder 6 is inserted to the inner side of placement ring 5 and elastic sheet 7, then, cylinder body 2 is placed into the inside of outer cylinder 1, then, handle 9 is rotated, handle 9 will drive cylinder body 2 to rotate, and since threaded segment 3 is connected with screw groove by screw thread, handle 9 drives cylinder body 2 to rotate and also synchronously descend at the same time, when cylinder body 2 descends, it also drives inner conical surface 4 to descend, at this time, inner conical surface 4 continuously contacts with elastic sheet 7, and continuously extrudes elastic sheet 7 when descending, so that elastic sheet 7 clamps inner cylinder 6, since protrusion 8 is elastic material and directly contacts with inner cylinder 6, it forms multiple-point flexible clamping to inner cylinder 6, which can effectively fix inner cylinder 6, prevent it from displacement or pouring due to shaking in carrying process, and also avoid damage to inner cylinder 6 due to rigid clamping.

[0027] When reaching destination, if inner cylinder 6 needs to be taken out, only need to rotate handle 9 reversely, cylinder body 2 will ascend, the extrusion force of inner conical surface 4 to inner cylinder 6 gradually reduces, elastic sheet 7 returns to initial state, and no longer exerts greater clamping force to inner cylinder 6, at this time, inner cylinder 6 can be easily taken out from the inner side of placement ring 5 and elastic sheet 7, so as to carry out subsequent experimental operation.

[0028] When rotating the handle 9, the state of the inner cylinder 6 should be observed continuously. Once it is felt that the inner cylinder 6 has been firmly fixed and there is no sign of any shaking or displacement, the rotation can be stopped. For example, when the outer cylinder 1 is shaken gently, the inner cylinder 6 can remain completely stationary, which indicates that the clamping force of the spring sheet 7 on the inner cylinder 6 is sufficient to effectively prevent the inner cylinder 6 from being displaced or tilted due to shaking during carrying.

[0029] The outer cylinder 1, the inner tapered surface 4 and the placement ring 5 protect the inner cylinder 6, reduce the risk of the inner cylinder 6 being broken due to collision during carrying and transportation, improve the overall impact resistance of the cylinder, reduce solution leakage and experiment interruption caused by cylinder breakage, facilitate carrying and ensure smooth experiment.

[0030] Reference Figures 3-5 A placement hole 13 is formed in the inside of the handle 9, and a blocking plug 10 is arranged in the inside of the placement hole 13. The bottom end of the blocking plug 10 is connected with a connecting rod 15, the bottom of the connecting rod 15 is connected with an elastic clasp 11, one end of the elastic clasp 11 is connected with a rod body 14, the elastic clasp 11 is located outside the cylinder body 2 and is in contact with the cylinder body 2. One end of the fixing ring 12 is fixedly connected with a connecting belt 16, one end of the connecting belt 16 is fixedly connected with the blocking plug 10, and the connecting belt 16 is made of flexible material.

[0031] When the inner cylinder 6 is fixed, the elastic clasp 11 has a certain elasticity and is internally provided with the rod body 14, so the elastic clasp 11 is sleeved outside the cylinder body 2 by using its own elasticity. At this time, the blocking plug 10 is inserted into the placement hole 13 of the handle 9. After the elastic clasp 11 is clamped, the elastic clasp 11 on both sides is pressed to make it close and lock (which is prior art). At this time, the elastic clasp 11 forms a stable locking structure with the cylinder body 2. Because the elastic clasp 11 is connected with the blocking plug 10, the blocking plug 10 can be stably arranged in the placement hole 13 and will not easily fall off or shift due to shaking, vibration or normal jolt during carrying and transportation. When carrying, only the connecting belt 16 on one side needs to be held to easily lift the entire portable pharmaceutical experiment cylinder.

[0032] Working principle: First, the solution measurement and the inner cylinder 6 preparation are performed. After the required solution is measured, it is poured into the inner cylinder 6, the inner cylinder 6 is inserted into the inside of the placement ring 5 and the spring sheet 7, and then the cylinder body 2 is placed into the outer cylinder 1. Then the handle 9 is rotated, the handle 9 drives the cylinder body 2 to rotate and descend, and the inner tapered surface 4 at the top of the cylinder body 2 descends and presses the spring sheet 7. The spring sheet 7 is elastically deformed, the elastic lugs 8 on the inside of the spring sheet 7 form flexible clamping on the inner cylinder 6, and the clamping force of the spring sheet 7 gradually increases with the continuous pressing of the inner tapered surface 4 until the inner cylinder 6 is firmly fixed. The rotation of the handle 9 is stopped after it is determined that the clamping degree is appropriate by observing that the inner cylinder 6 has no displacement or shaking when the outer cylinder 1 is shaken.

[0033] After that, the elastic snap ring 11 is sleeved outside the barrel 2 and is adhered by its elasticity, the plug 10 is inserted into the placement hole 13 of the handle 9, the two sides of the elastic snap ring 11 are pressed to be locked, since the plug 10 is connected with the elastic snap ring 11, the plug 10 is stably placed in the placement hole 13, and is prevented from falling off and moving due to external factors, at this time, the whole device is locked, and can be carried by holding the connecting belt 16.

[0034] When the inner barrel 6 needs to be taken out at the destination, the plug 10 and the elastic snap ring 11 are taken out first, then the handle 9 is reversely rotated, the barrel 2 is lifted, the extrusion force of the inner conical surface 4 on the inner barrel 6 is reduced, the elastic sheet 7 restores the original state and loosens the inner barrel 6, and then the inner barrel 6 can be taken out for subsequent experimental operation.

[0035] The above is only the preferred embodiment of the present application, and does not limit the technical range of the present application, so any slight modification, equivalent change and modification of the above embodiment according to the technical essence of the present application still belongs to the technical scheme of the present application.
