A kind of band shell cassette mechanism structure
Technical field
This utility model belongs to level technical field, particularly relates to a kind of band shell cassette mechanism structure.
Background technology
Level, or claim marker, it is a kind of to send horizontal or vertical visible laser, at target face subscript water filling horizontal line or the instrument of vertical line.Level is owing to possessing measurement miscellaneous function, so having many more accurate parts, precise part also can be carried out a range of being automatically adjusted location with compensator by himself.And level relatively greatly, surprisingly lands in outside environmental vibration; or during by impact, shock; owing to lacking protection; precise part and the instantaneous stress of compensator is excessive, displacement excessively; easily cause the compensator carried on level impaired, thus cause the parts such as compensator recovery deficiency, movement to be automatically adjusted the problems such as location is inaccurate.
Utility model content
This utility model is to overcome deficiency of the prior art, it is provided that a kind of reasonable integral structure, can effectively antidetonation, shock resistance, there is the band shell cassette mechanism structure of discretionary protection ability.
To achieve these goals, this utility model is by the following technical solutions:
nullA kind of band shell cassette mechanism structure,Including by left casing、The outer cage that right casing is assembled,Movement group it is provided with in described outer cage,Described movement group is provided with two left mounting posts、Two right mounting posts,Described left casing、Left side fixed plate it is respectively equipped with in right casing、Right side fixed plate,Described left casing is provided with two left snares,Described left mounting post is provided with left shock absorbing ring,Two left shock absorbing rings in two left mounting posts and two left snare one_to_one corresponding,In described left shock absorbing ring stretches into corresponding left snare and extrude mutually with corresponding left snare,Described left shock absorbing ring passes left side fixed plate,Described left side fixed plate is towards surface and the left chassis contact of left casing,Described right casing is provided with two right snares,Described right mounting post is provided with right shock absorbing ring,Two right shock absorbing rings in two right mounting posts and two right snare one_to_one corresponding,In described right shock absorbing ring stretches into corresponding right snare and extrude mutually with corresponding right snare,Described right shock absorbing ring passes right side fixed plate,Described right side fixed plate is towards surface and the right chassis contact of right casing,Described left side fixed plate、Right side fixed plate is all and horizontal plane.Outer cage is divided into left and right two halves, and the structure between movement group and outer cage is also separated, and but, is all used as skeleton by side fixed plate between it, utilizes the connection between shock absorbing ring with mounting post, snare to coordinate, and realizes location.Movement group can be carried out spacing by side fixed plate one; two supporting constructions being used as shock absorbing ring; shock absorbing ring can be allowed to be in all the time between movement group and outer cage; thus; when being given a shock, impacting; shock absorbing ring, as intermediary, can play strong shock absorbing, cushioning effect, protects the structures such as movement group.
As preferably, described movement group is provided with left mounting seat, right mounting seat, described left mounting seat is provided with left mounting groove, described right mounting seat is provided with right mounting groove, described left side fixed plate, fixed plate lower end, right side are equipped with lower protuberance, lower protuberance in the fixed plate of left side is stuck in left mounting groove, and the lower protuberance in the fixed plate of right side is stuck in right mounting groove.Left side fixed plate, fixed plate lower end, right side (lower protuberance) are separately fixed in two mounting grooves; and left side fixed plate, right side fixed plate are each passed by two shock absorbing rings; so having the effect of three-point fix; can guarantee that the stability of structure; and reduce the probability of shock absorbing ring displacement, maintain good damping, subtract punching, protected effect.
As preferably, described left casing is provided with groove under left housing, and described right casing is provided with groove under right shell, and described left mounting seat is under left housing within groove, and described right mounting seat is under right shell within groove.Groove under two shells is utilized to position two mounting seats respectively so that outer cage can preferably coordinate with movement group, contacts, position.
As preferably, described left shock absorbing ring includes that coaxial left ring support, left loop pillar, left ring support, left loop pillar are formed in one structure, and described left ring support is socketed in the left mounting post of correspondence, and described left loop pillar stretches in the left snare of correspondence;Described right shock absorbing ring includes that coaxial right ring support, right loop pillar, right ring support, right loop pillar are formed in one structure, and described right ring support is socketed in the right mounting post of correspondence, and described right loop pillar stretches in the right snare of correspondence.Although shock absorbing ring is integrated formed structure, but it is divided into two different pieces, for coordinating with different structure, so can improve the fitness between attachment structure, strengthen locating effect.
The beneficial effects of the utility model are: rational in infrastructure, relative symmetry, have shock absorbing ring structure, it is possible to play good damping, shock resistance, protected effect, are beneficial to maintain cassette mechanism structure and carry the service life of compensator structure;There is the left side auxiliary stopper structure such as fixed plate, right side fixed plate, the relatedness between overall structure can be strengthened, shock absorbing ring effectively can be positioned again, improve the stability in its work process.
