Abstract
The utility model relates to a positioning column structure for proofing the loosing of a silica gel safety contact of a financial POS machine. The positioning column structure includes a positioning column main body in interference fit with the silica gel safety contact, and the positioning column structure is characterized in that a plurality of protruding ribs are distributed on the periphery of the positioning column main body. The positioning column structure provided, being simple in structure, can better clamp the silica gel safety contact with the silica gel positioning column at the upper cover or the lower cover to increase the rotation friction and clamping force, and thereby the production efficiency cannot be influenced because of the coming off of the silica gel safety contact during the production process.
Description
Technical field
The utility model relates to the plastic cement reference column structure that a kind of silica gel safety contact that prevents financial POS machine inside gets loose, and is applicable in various financial POS machine upper and lower covers the structural design of the plastic cement reference column for assembling the silica gel safety contact.
Background technology
All be provided with a plurality of silica gel safety contacts on financial POS machine, after the POS machine is disassembled privately, software systems newspaper attack automatically when silica gel safety contact and motherboard contact are contactless, make the disabler of POS machine, need again transfer to dress Software tool under POS machine issuer can re-use, thereby increases the security performance of POS machine.
The silica gel safety contact is all that design and installation is on the plastic cement reference column of upper cover or lower cover, the plastic cement reference column is that the light face is cylindrical, with the silica gel safety contact, adopt the interference mode to coordinate, but, because both contacts area are little, clamping force is little, in factory-assembled POS machine production run, before each parts such as mainboard and upper and lower covers are not assembled together fully, because production line vibration or operator rock while taking upper and lower covers, the silica gel safety contact just is easy to get loose drop, and causes affecting production efficiency.
The utility model content
The purpose of this utility model is to provide a kind of reference column structure that prevents that financial POS machine silica gel safety contact from getting loose, and contributes to solve in POS machine procedure for producing the problem that the silica gel safety contact easily gets loose.
The technical solution of the utility model is: a kind of reference column structure that prevents that financial POS machine silica gel safety contact from getting loose, comprise and the reference column main body of silica gel safety contact interference fit, it is characterized in that: the perimembranous of described reference column main body is evenly equipped with some protrusion muscle.
Wherein, described protrusion muscle is 8, and the xsect of described reference column main body becomes the rice font.
Described protrusion muscle is 6, and the xsect of described reference column main body becomes blossom type.
The perimembranous of described reference column main body also is evenly equipped with 4 brace rods.
Interference fit between described silica gel safety contact and reference column main body is controlled in 0.05-0.3mm.
The utility model has the advantage of: the utility model is simple in structure, can better the plastic cement reference column of silica gel safety contact and upper cover or lower cover be tightened, strengthen rotation friction and clamping force, avoid silica gel safety contact in procedure for producing come off and affect production efficiency.
The accompanying drawing explanation
The structural representation that Fig. 1-3 are the utility model embodiment.
Embodiment
For above-mentioned feature and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below.
With reference to figure 1, Fig. 2 and Fig. 3, the utility model relates to a kind of reference column structure that prevents that financial POS machine silica gel safety contact from getting loose, and comprises and the reference column main body 1 of silica gel safety contact interference fit, and the perimembranous of described reference column main body 1 is evenly equipped with some protrusion muscle 2.
Above-mentioned protrusion muscle 2 is 8, and the xsect of described reference column main body becomes the rice font, as Fig. 1.
Above-mentioned protrusion muscle 2 is 6, and the xsect of described reference column main body becomes blossom type, as Fig. 3.
The perimembranous of above-mentioned reference column main body 1 also is evenly equipped with 4 brace rods 3.
Above-mentioned silica gel safety contact and the interference fit between the reference column main body are controlled in 0.05-0.3mm.
Specific implementation process:
Fig. 1 shows first embodiment of the present utility model:
The plastic cement reference column coordinates with the silica gel safety contact, and the location column length has meter font to protrude totally 8 of ribs.The internal diameter of safety contact is ￠ 3.5mm, the protrusion rib external diameter of reference column is ￠ 3.8mm, the face of cylinder of not protruding is ￠ 3.6mm, utilize scalability and the plastic cement reference column wringing fit of silica gel safety contact to clamp, effectively strengthen the friction force between safety contact and reference column, particularly spin friction power.
Fig. 3 shows second embodiment of the present utility model:
The plastic cement reference column coordinates with the silica gel safety contact, and the location column length has totally 6 of blossom type ribs.The internal diameter of safety contact is ￠ 3.5mm, the protrusion rib external diameter of reference column is ￠ 3.8mm, the face of cylinder of not protruding is ￠ 3.6mm, utilize scalability and the plastic cement reference column wringing fit of silica gel safety contact to clamp, effectively strengthen the friction force between safety contact and reference column, particularly spin friction power.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model
