Abstract
A glove box clasp tooth engagement-type quick opening device comprises a cylinder with a glass cover plate on the nozzle of the cylinder. The cylinder is respectively connected with an inert gas steel cylinder and a vacuum pump through pipes. The cylinder is also connected with a vacuum gauge. The invention is characterized in that tooth blocks are evenly connected on the exterior margin of the nozzle; the upper end face of the nozzle is grooved; a seal rubber ring is arranged in the groove; the upper edge of a clasp is fit to the glass cover plate; tooth blocks which are the same with the tooth blocks arranged on the exterior margin of the nozzle are evenly connected on the inner side of the lower edge of the clasp; the cylinder is connected with a quick-opening valve. The utility model makes use of the courses of vacuum-pumping and filling shielding gas during using the glove box to achieve self-closing and safety requirement of the glove box tooth engagement quick-opening device without requiring to add an additional tightening device and a safety interlock. The utility model has the advantages of simple structure, convenient usage and excellent sealing property. The utility model is widely applicable to the operation for sealing production process of processing inflammable and explosive materials.
Description
Technical field
The utility model relates to the switching device of glove box, is specifically related to glove box snap ring Tooth-locked Quick Closure device.
Background technology
Glove box is widely used in physio-chemical study, the new material developmental research, many technical fields such as Development and Production of production and biological medicine, common glove box generally adopts the fastening bolt hermetically-sealed construction, the mounting or dismounting time is long, labour intensity is big, frequent mounting or dismounting make bolt impaired easily, can't satisfy the needs of frequent intermittent operation, especially to the processing of inflammable explosive article, need under inert gas shielding, produce, it is particularly important that the seal of glove box just seems, although existing Tooth-locked Quick Closure device can satisfy the requirement of fast opening and closing, but in order to reach sealing and safety requirements, usually need to step up device and safety interlocking, complex structure, economic performance is poor, is not suitable for large-scale industrialization and uses; Simultaneously in the scientific experiment process, increasing new material is extremely responsive to water, oxygen, the very difficulty that becomes is handled in operation and experiment to these materials, if it is poorly sealed or careless slightly, also can scientific research personnel's life security be worked the mischief, seriously restricted scientific research personnel's process of the test and test result.
Summary of the invention
The purpose of this utility model provides a kind of glove box snap ring Tooth-locked Quick Closure device, overcomes long, big, the frequent mounting or dismounting of labour intensity of existing glove box mounting or dismounting time and makes equipment impaired easily, and sealing is poor, shortcomings such as complex structure.
Glove box snap ring Tooth-locked Quick Closure device, glove box is a cylindrical shell, and there is glass cover-plate the nozzle top, and cylindrical shell is connected with inert gas steel cylinder, vavuum pump respectively through pipeline, also is connected with vacuum meter on the cylindrical shell, it is characterized in that:
A) at the uniform tooth piece that is connected with of nozzle outer rim, the nozzle upper surface has groove, and sealing rubber ring is set in the groove;
B) snap ring upper edge and glass cover-plate kiss connects, the inboard uniform tooth piece identical with the nozzle outer rim that be connected with in lower edge;
C) also be connected with quck-opening valve on the cylindrical shell.
Advantage of the present utility model and good effect are: utilize the process that vacuumizes and fill protective gas in the glove box use; realize closing certainly and safety requirements of glove box snap ring Tooth-locked Quick Closure device; and need not increase extra device and the safety interlocking of stepping up; simple in structure, easy to operate, favorable sealing property have obvious superiority.
Below in conjunction with drawings and Examples the utility model is done and to be described in further detail.
