The tablet hardness detector adopts the structure that a front cover is arranged at the front end of a cylinder body; a testing seat is arranged at the front end of the front cover; a testing probe is arranged at the center of the front cover; the testing probe is connected with the front cover in a sliding manner; a spring arranged inside the cylinder body is connected with the tail end of the testing probe; a baffle is arranged at the tail end of the spring; a rear cover is arranged at the tail end of the cylinder body; the rear cover is in threaded connection with a screw; the front end of the screw is arranged inside the cylinder body and the end part of the screw is fixedly connected with a rotary table; the rotary table and the baffle are connected with each other through a ball joint; the tail end of the screw is arranged behind the rear cover and fixedly connected with a handle; a pointer chute is formed on the cylinder body; the tail end of the testing probe is connected with a front pointer; the baffle is connected with a rear pointer; and length scales are formed on one side of the pointer chute. The tablet hardness detector has the advantages of simple structure, safe and reliable detection process, convenient use and easy disassemble and maintenance.
Description
Technical field
The utility model relates to pharmaceutical test technique with the apparatus field, specifically a kind of tablet hardness detecting device.
Background technology
General, the quality of medicinal tablet directly influences the security of its drug effect and medication.Therefore can be divided into inspection aspect three of chemistry, physics and the hygienes in the quality check of tablet.At the inspection of physics aspect, comprise outward appearance, mass discrepancy, hardness, disintegration time limited and Packing Condition etc.Especially tablet has suitable hardness, in order to avoid broken or wearing and tearing in processes such as packing, transportation.The disintegration of hardness and tablet and stripping also have substantial connection.The testing tool at the tablet hardness index under prior art exists is of all kinds, but all relatively fuzzyyer and inaccurate to the test result of hardness.How to design in one statement more intuitively and can reflect that maybe the apparatus of test result is the big event that the drug abuse test aspect remains to be researched and developed.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of tablet hardness detecting device is provided.
The technical solution of the utility model realizes in the following manner, this tablet hardness detecting device, its structure is that barrel front end is provided with protecgulum, the protecgulum front end is provided with the examination seat, the protecgulum center is provided with test point, test point and protecgulum are slidingly connected, the test point end is connected with the spring that is arranged in the cylindrical shell, spring end is provided with baffle plate, and barrel tip is provided with bonnet, and bonnet is connected with a screw flight, screw front end is arranged in the cylindrical shell and the end is fixedly connected with rotating disk, rotating disk is connected by ball pivot with baffle plate, and the screw rod end is arranged at the bonnet rear, the terminal fixedly connected jug of screw rod; Offer the pointer chute on the cylindrical shell, the test point end is connected with prior pointer, and baffle plate is connected with backpointer, and pointer chute one side is carved with the length scale.
Protecgulum is connected with cylinder screw.
Bonnet is connected with cylinder screw.
The beneficial effect that the utility model is compared with prior art produced is:
This tablet hardness detector design is reasonable, simple in structure, testing process is safe and reliable, easy to use, be easy to dismounting and safeguard.It utilizes the character of spring to realize mensuration to the dynamics of a compelling force of tablet, thereby comes the hardness property that reflects tablet of standard.This tablet hardness detecting device is stuck in tablet to be measured between test point and the examination seat in use earlier, the distance of two pointers before and after record and the calculating, rotating handles then, make the screw rod propelling spring that advances, spring is given external force of test point under stressed effect, force the broken tablet of test point, the distance of two pointers before and after this moment record and calculating, the elasticity coefficient that the difference of priority two numerical value is multiplied by spring is exactly the deformation power of spring, promptly is the numerical value reflection to the strength of tablet externally applied forces.So test, simple and convenient, the result is accurate, and test is fast.
