The gear oil pump model casing can effectively store a gear oil pump, and separate large components and small components for standard management in teaching, thereby providing convenience for students to search for and distinguish corresponding components and raising learning quality; in addition, concentrated and standard management of components provides convenience for counting and searching, minimizes the possibility of loss, and furthermore effectively guarantees that the teaching oil pump can be repeatedly used in turn in different classrooms, so that college teaching cost can be reduced.
Description
Technical field
The utility model relates to the storage of teaching aid in teaching practice and receives case, the gear oil pump model casing that specifically a kind of teaching practice is used.
Background technology
The teaching method of China's tradition vocational education pattern is take " knowledge is as one's own department or unit ", emphasizes the science and systematicness of subject knowledge, focuses on the contact between new and old knowledge.But it has been ignored student ability and creationary cultivation, can not emphasize that with society the quality-oriented educations such as practical technical ability, knowledge innovation synchronize, be difficult to adapt to social development need.In view of this, most of middle and high duty universities and colleges have offered with student and have learned the practice course of suiting one's training.Wherein, practice course mechanical or nearly mechanical speciality is generally gear oil pump mapping, survey and draw by gear oil pump, make student understand method and the step of part mapping, with the correct free-hand drafting part of picture step sketch, draw part drawing according to part sketch with CAD again, grasp the graphic plotting skill of planar design, thereby cultivate student's actual operational capacity and team's interchange team sense and ability.
Teaching aid-the gear oil pump of putting into practice mechanical or nearly mechanical speciality is comparatively complicated mechanical principle parts, has more than ten to plant non-standard component and conventional part in its assembly, and the standard component (comprising screw, packing ring, nut, key, pin etc.) of more than 20.In teaching process, student need to carry out dismounting, mapping and assembling etc. repeatedly to gear oil pump, for adapt teaching requires and is convenient to the different students of class to use in turn study, management (be no matter the overall of assembling, or the split of dismounting) is received in the storage that need in teaching process, every sleeve gear oil pump be concentrated.But, receive management box owing to there is no at present the storage of special teaching gear oil pump, in actual teaching process, student is by scattered parts numerous on gear oil pump, mixed and disorderly stacking, situation is that those parts are concentrated in a chest preferably, this makes student in the time of study, need in numerous parts, to find corresponding mapping parts like " looking for a needle in a haystack ", not only look for that to get difficulty large, efficiency is low, affect Students ' Learning quality, and the type of these parts that are not easily distinguishable, mislead students study, further affect Students ' Learning quality, more seriously, this scattered, nonstandard stacking management very easily makes the small parts loss of being scattered, thereby affect the follow-up student's of class teaching practice, cause universities and colleges need to spend a large amount of funds and again buy more frequently the new teaching aid-gear oil pump of putting into practice, significantly increase the instruction cost of universities and colleges.
Summary of the invention
The purpose of this utility model is: for singularity and the deficiencies in the prior art of above-mentioned teaching practice, and the gear oil pump model casing of provide a kind of simple in structure, with low cost, durable in use, convenient management, concentrating standard, reliable and practical teaching practice to use.
The technical solution adopted in the utility model is: the gear oil pump model casing that a kind of teaching practice is used, receive teaching gear oil pump for storage, described model casing comprises open-topped casing and case lid, the inner chamber of casing is greater than the profile of gear oil pump, the top side wall of casing is hinged with multiple buttons that cover by hinge, the open top of the corresponding casing of size of described case lid, case lid is buckled on casing by covering padlock, by the shutoff of casing top.
The sidewall of described casing is provided with the deep trouth of indent, is equipped with the push-and-pull drawer box of coupling deep trouth profile in this deep trouth; On the casing of described deep trouth side, be hinged with solid box pin by hinge.
Described solid box pin is bending domes, and its outer end is flat and towards casing, Gu be provided with tensioning spring between the sidewall of the outer end of box pin and hinge or casing.
The rectangular shape of indent deep trouth end face on described wall box; Described push-and-pull drawer box is assemblied in by rail plate pair in the deep trouth of wall box, and the panel of push-and-pull drawer box is provided with drawing handle.
The deep trouth of described wall box is in the bottom of casing the position near corner.
In described push-and-pull drawer box, be provided with at least one dividing plate, push-and-pull drawer box be separated into multiple different storages and receive region.
Described casing is composited by the epoxy resin layer of inside and outside layer and the weaving steel wire mixolimnion in middle layer.
The top of described case lid is hinged with carrying handle by hinge.
The beneficial effects of the utility model are: said structure is simple, with low cost, long-lived model casing is for the teaching practice singularity of mechanical or nearly mechanical speciality and design, it can carry out effectively storage to gear oil pump and receive, and large parts while making to impart knowledge to students separate the management of standard with little parts, thereby facilitate student to find, distinguish corresponding parts, improve learning quality, and parts are concentrated, the management of standard, be conducive to check easily, find, the possibility of losing that makes to be scattered drops to minimum, and then effective guarantee teaching gear oil pump can be between different classes in turn, Reusability, reduce the instruction cost of universities and colleges, reliability is high, practical.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is a kind of structural representation of the present utility model.
Code name implication in figure: 1-push-and-pull drawer box; 2-casing; 3-case lid; 4-carrying handle; 5-cover button; Gu 6-box pin; 7-drawing handle.
Embodiment
Referring to Fig. 1: the utility model is received teaching gear oil pump for storage, and it comprises open-topped casing 2 and case lid 3.In order to adapt to weight, the guarantee structural strength and convenient for cleaning of gear oil pump, casing 2 adopts composite structure moulding, be casing 2 by the epoxy resin layer of inside and outside layer and the weaving steel wire mixolimnion in middle layer be composited (epoxy resin layer due to smooth, fine and smooth, without adsorbability, thereby be convenient to grease class dirt and clean); The inner chamber of casing 2 is slightly larger than the profile of the length of gear oil pump, and the top of four sidewalls of casing 2 is hinged with four (can be also three or two) by hinge can covering of upper and lower upset detain 5.Case lid 3 does not have weight-bearing function because of it, thereby it can adopt the molding structure of casing 2, can adopt other common molding structure yet; The open top of the corresponding casing 2 of size of case lid 3, the groove that the outer rim place, bottom surface of case lid 3 has correspondence, coupling casing 2 opening's edges fastens track, and case lid 3 cover buckles, on casing 2, by the open top shutoff of casing 2, and latch on casing 2 by covering button 5; The end face centre of case lid 3, by hinge be hinged with can 180 ° of upsets carrying handle 4, do not hindering under the prerequisite of use, be convenient to raise case lid 3 from casing 2.
