Abstract
The utility model relates to a measure technology field, and specially relates to a steel lock fastener used for a measuring instrument box. The steel lock fastener used for a measuring instrument box is characterized by comprising a fastener ring and a fastener hook. The fastener hook comprises a base plate and a hook. The fastener ring comprises a hook ring, a fastener handle, a fixing hole and a base plate; the fixing hole is positioned in the base plate; the fastener handle is provided with a slit passing through the fixing hole; the fastener handle and the base plate are provided with apertures through which a spring assembly goes, and the fastener handle is hinged to the base plate in a fixed connection manner; and the hook ring passes through the aperture at the side surface of the fastener handle to be hinged to the fastener handle. The spring assembly tightly presses the hook ring to guarantee stability, the wear resistance is good, usage is convenient, installation is fast, and the replaceability is high.
Description
Technical field
The utility model relates to field of measuring technique, is specifically related to a kind of snap close piece of the steel for the surveying instrument case.
Background technology
Our the most frequently used instrument container is all some simple plastic buckles at present.For example the TCR802power total powerstation, simple and easy to use, and cost is also very cheap.The non-constant of the wearing quality of this instrument container fastener, fastener easily comes off and damages, and the fastener damaged can't be changed.Due to field operation in-site measurement situation complexity, it is improper that instrument container is placed, and runs into some and stumble and all can make fastener damage, and the most important thing is to cause breaking of instrument.
The utility model content
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art part, and a kind of snap close piece of the steel for the surveying instrument case is provided, and by spring assembly, supports the Button Handle structure, by being connected of clasp and clasp guaranteeing the firm of instrument container, wearing quality is good, easy to use, quick for installation.
Realization of the present utility model is completed by following technical scheme:
A kind of snap close piece of the steel for the surveying instrument case, it is characterized in that this fastener is comprised of clasp and clasp, described clasp consists of shackle, Button Handle and base plate, stator vertically is set on described base plate, described Button Handle is provided with slit, described slit and described stator plug-in mounting coupling, described Button Handle is connected with described base plate hinged, and described shackle and described Button Handle are articulated and connected.
Hinged place between described Button Handle and described base plate is provided with stage clip.
Described stator is provided with lockhole.
The utility model has the advantages that, but the built-in spring self-return of fastener, automatic fastening, fastening force is stable can not eject base plate easily, under judder, can locate not wavy
;what the utility model fastener adopted is that screw is installed, and is convenient to change the damage parts
;easy to use, quick for installation
;fastener can be gone up padlock, guarantees special messenger's special use, in the long-distance safety that can also guarantee instrument in service.
The accompanying drawing explanation
Accompanying drawing 1 is the utility model fastener installation position figure;
Accompanying drawing 2 is the utility model structural representation;
Accompanying drawing 3 is the utility model steel snap close piece Unclosing structure schematic diagram;
Accompanying drawing 4 is the utility model finished figure.
Embodiment
Below in conjunction with accompanying drawing, by embodiment, the utility model feature and other correlated characteristic are described in further detail, so that technician's of the same trade understanding:
As Figure 1-4, in figure, mark 1-13 is respectively: clasp 1, clasp 2, dull and stereotyped 3, link up with 4, shackle 5, Button Handle 6, stator 7, screw 8, stage clip 9, base plate 10, instrument container 11, slit 12, lockhole 13.
Embodiment: as Figure 1-4, the present embodiment fastener is for instrument container 11, and this fastener is the steel snap close piece, comprises clasp 1, clasp 2.Fix by screw 8 and instrument container 11 screws respectively on the flat board 3 of clasp 1 and the base plate 10 of clasp 2, be about to clasp 1 and clasp 2 and instrument container 11 fastened by screws.
Pull open in use Button Handle 6, shackle 5 is pushed ahead, shackle 5 and hook 4 are articulated, now extension spring 9 is in tensioning state, can make it automatically reset unclamping Button Handle 6 rear compression springs 9, and shackle 5 embeds in hook 4 and forms the state that strains at, stator 7 is through slit 12 simultaneously, and lockhole 13 is exposed outside slit, fastening force is stable guarantees its not flyout panel easily, under judder, can locate not wavy.Lockhole 13 places can arrange padlock, guarantee special messenger's special use, in the long-distance safety that can also guarantee instrument in service.The parts that can damage by unloading the screw quick-replaceable during each parts damages of fastener.
Fastener wearing quality in the present embodiment instrument container is good, and do not have obscission and occur, and also easy to use, quick for installation
;even it is improper that instrument container is placed, run into some instrument container fasteners of stumbling not fragile, even if also can replace easily while being damaged
;fastener can be gone up padlock, guarantees special messenger's special use, in the long-distance safety that can also guarantee instrument in service.
