Abstract
The utility model relates to a waterproof electronic digital display caliper. A sealed cavity is formed by a substrate and a hood on the caliper frame. A round moving grating, a round static grating, an electronic chip and a display screen are arranged in the sealed cavity. The round moving grating is connected with a gear shaft and a gear. A seal ring is arranged in the middle part of the gear shaft to ensure the sealing of the sealed cavity. The gear is meshed with the rack arranged on the side face of the caliper body. In this way, through the rack and the gear transmission theory, the linear displacement between the caliper body and the caliper frame against each other is changed into the capacitance signal variation between the round moving grating and the round static grating in the sealed cavity. Therefore, the waterproof performance of the electronic digital display caliper is guaranteed.
Description
Affiliated technical field
The utility model relates to the measurer of a kind of linear measure longimetry in the measurer industry, and this measurer especially can be prevented the infiltration of sealing, is a kind of a kind of waterproof digimatic calipers with high water resistance.
Background technology
At present, known digimatic calipers is made up of with the moving grid and the digital display chip that are installed on the chi frame the strip fixed grid that is installed on the blade.Because this technology is to form by holding the grid principle design, the strip fixed grid is mounted in the blade upper surface, and moving grid is mounted in chi frame upper surface, and the strip fixed grid that is installed on the blade is exposed to outside.As long as the user has media such as water, oil, cutting fluid to drop on the fixed grid surface in use, because the medium between moving, the fixed grid changes, digimatic calipers just can not be worked immediately, so the digimatic calipers environment for use requires harsh, can not contact water, wet goods medium, bring constant to the user.
Summary of the invention
Can not this weak point of waterproof in order to overcome existing digimatic calipers, the utility model provides a kind of waterproof digimatic calipers, this waterproof digimatic calipers can not only use under the environment that media such as water, oil, cutting fluid are arranged, and can use under water, has high water proofing property.
The technical scheme that its technical matters that solves the utility model adopts is: it is made up of blade parts, chi members of frame, electronic chip element, display window parts four big parts.The blade parts are made up of blade, tooth bar, and tooth bar is installed in the blade upper side, and adopt screw retention to link to each other each other.The chi members of frame is made up of chi frame, substrate, gear, gear shaft, circular moving grid, O-ring seal.Above the chi frame substrate is housed, gear shaft is housed on the substrate, gear is equipped with in the gear shaft lower end, and O-ring seal is equipped with in the centre, and circular moving grid is equipped with in the upper end, and gear shaft can freely rotate.Electronic chip element is made up of chip board, chip, circular fixed grid, and chip board and substrate are fixedly linked, and circular fixed grid and chip board are fixedly linked, and circular fixed grid is coaxial with circular moving grid, certain interval is arranged between up and down.The display window parts are made up of display screen, case, and display screen is installed on the case, and case and substrate are fixedly linked.Blade and chi frame adopt and are slidingly matched, and can freely spur each other.Major technique feature of the present utility model is: case is installed on the substrate, forms an annular seal space between the two, and circular fixed grid, circular moving grid, chip board, chip, display screen are housed in annular seal space.Circular moving grid is fixed on the gear shaft upper end, and gear is equipped with in the gear shaft lower end, gear shaft and substrate be the hole axle movingly.One O-ring seal is housed on gear shaft below the substrate, has guaranteed annular seal space and extraneous sealing.And be exposed at the wheel and rack that has only outside the annular seal space, thereby guaranteed the water-proof function of mechanism.
The condenser type that the utility model will not possess water-proof function moves, fixed grid is retrofitted in the annular seal space, and made circular moving, fixed grid into, and the high-accuracy mechanical tooth bar, the gear that are exposed to the outside come transmission accuracy, have so both guaranteed the measuring accuracy of slide calliper rule, have guaranteed the water proofing property of slide calliper rule again.
The beneficial effects of the utility model are, have both guaranteed the measuring accuracy of waterproof electronic caliper, have guaranteed its very high water proofing property again, and are simple in structure.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is original digimatic calipers synoptic diagram.
Fig. 2 is a front elevation of the present utility model.
Fig. 3 is the utility model cracking-off display window parts front views.
Fig. 4 is the I-I cut-open view of Fig. 2.
Fig. 5 is the partial enlarged drawing of Fig. 4.
Among the figure: (1) strip fixed grid (2) blade (3) chi frame (4) case
(5) display screen (6) substrate (7) chip (8) chip board
(9) tooth bar (10) gear (11) gear shaft (12) O-ring seal
(13) the circular moving grid of circular fixed grid (14)
Embodiment
In Fig. 3, substrate (6) is installed in chi frame (3) and goes up the plane, is fastenedly connected with screw between mutually, and form a rectangle slotted eye, blade (2) is installed in the rectangle slotted eye of substrate (6) and chi frame (3) formation, for being slidingly matched, can freely spur each other between blade (2) and the chi frame (3).Tooth bar (9) is installed in blade (2) upper side, tightens up with screw each other.Chip board (8) is installed on the substrate (6), tightens up with screw each other.
In Fig. 4, gear shaft (11) is installed in the hole of substrate (6), guarantee gear shaft (11) play not up and down, but gear shaft (11) is free to rotate.Gear shaft (11) lower end is gear (10), gear (10) and tooth bar (9) engagement.
In Fig. 5, a circular moving grid (14) is equipped with in gear shaft (11) upper end, and an O-ring seal (12) is housed in the middle of gear shaft (11), guarantees the cooperatively interact sealing in hole of substrate (6) and gear shaft (11).
In Fig. 4, chip (7) is installed on the chip board (8), and circular fixed grid (13) is installed on the chip board (8), and circular fixed grid (13) is concentric with circular moving grid (14), and certain interval is arranged up and down.
In Fig. 2, display screen (5) is contained on the case (4), does not have the gap each other and cooperates.
In Fig. 4, case (4) is contained on the chi frame (3), tightens up with screw.Case (4) forms an annular seal space with substrate (6).
When the user spurs blade (2), be contained in the also pulling thereupon of tooth bar (9) on the blade (2), then rotate with tooth bar (9) meshed gears (10) thereupon, the circular moving grid (14) that links to each other with gear shaft (11) simultaneously also rotates thereupon, just forms circular moving grid (14) and circular fixed grid (13) rotation each other at last.Like this when blade (2) and chi frame (3) each other during linear displacement, by the rack pinion transmission principle, become circular moving grid (14) and circular fixed grid (13) capacitance signal variation each other, electronic chip (7) carries out data processing according to the capacitance variations signal of input, last electronic chip (7) will be handled measurement data input panel (5), display screen (5) shows measurement data, and the gauger just can directly read the measurement data result on display screen (5).
