Compared with prior art, drop resistant of the present utility model and the instrument shell structure for being easy to safeguard, installation and removal side
Just it is quick, by the way that instrument front end is stuck in neck, then connecting rod right-hand member is inserted into quick locknut, until procapsid
The fin bar of wall end and the groove of rear shell body wall end block completely, and now the external screw thread of connecting rod right-hand member also extends to quickly
Locking nut right-hand member is outer, and quick locknut is slidably connected with connecting rod, and the external screw thread of connecting rod right-hand member now plays
Limitation back casing separates with procapsid, and certainly, plastic net-board can also prop up instrument rear end in the presence of second spring, whole
The first spring and second spring and rubber seal can play three-level bradyseism effect, the first bullet when instrument housing falls
Spring and second spring play bradyseism effect to instrument, and rubber seal plays bradyseism effect to shell structure, so as to prevent instrument
With breaking for shell structure, also quickly connecting rod can be removed from back casing during instrument so as to quickly open when maintenance.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is scheme of installation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment is further described to the utility model, in the signal of this utility model
Property embodiment and explanation be used for explaining the utility model, but be not intended as to restriction of the present utility model.
A kind of drop resistant as shown in Figure 1 and Figure 2 and the instrument shell structure for being easy to safeguard, including procapsid 1, back casing 9,
The right side of procapsid 1 is provided with a circle fore shell body wall 2, and the end of fore shell body wall 2 is provided with fin bar 4, the lateral wall two of fore shell body wall 2
Side is located at the right side of procapsid 1 and is vertically and fixedly provided with connecting rod 8, and the right-hand member of connecting rod 8 is provided with external screw thread 81, the right-hand member of procapsid 1
Face is located at the neck being provided with fore shell body wall 2 for fixed instrumentation 17, vertical connection between the end of cell wall 6 of neck and instrument 17
There is the first spring 7, the procapsid 1 between neck is provided with transparency window 3, and the left side of back casing 9 is provided with a circle rear shell body wall
11, the end of rear shell body wall 11 is provided with the groove 12 being engaged with fin bar 4, and rubber seal 13, institute are provided with the groove 12
State be vertically and fixedly provided with the back casing 9 of the lateral wall both sides of rear shell body wall 11 be engaged with the external screw thread 81 of the front end of connecting rod 8 it is fast
Fast locking nut 10, after the fin bar 4 of the current end of housing wall 2 blocks completely with the groove 12 of the end of rear shell body wall 11, now
The external screw thread 81 of the right-hand member of connecting rod 8 is extended to outside the right-hand member of quick locknut 10, and now quick locknut 10 is slided with connecting rod 8
