Abstract
The invention discloses a mechanical protecting electronic digital display caliper rule. a protection frame is disposed on the upper part of the front side of the rule body for isolating the rule body from hand; the protection frame comprises a support and a rail or cover cap; the supports are disposed on both ends of the rule body; the rail or cover cap is disposed between the two supports to form a space from the front side of the rule body; the disposed height of the rail or cover cap is larger than the ruler frame. The mechanical protecting electronic digital display caliper in the present invention can protect the ruler body front side from contacting with the sweat or cooling agency on hand, or other substances containing electrolytes, thereby can prevent display function failure, guarantee the normal use of the electronic digital display caliper, consequently, achieves the advantages of wide suitable rang, convenient using, high popularity rate wide market prospect and high economic benefit.
Description
(1) technical field:
The present invention relates to digimatic calipers.
(2) background technology:
Digimatic calipers (abbreviation digital display calliper) is a kind of precision measurement of length instrument, and most capacitor grid transducers that adopt are made.The main part grizzly bar of capacitor grid transducer (adding a cover the copper-clad plate bar of plastic film behind the accurate groove) is affixed on the blade front, in use, sweat on the palm, cutting fluid or other contain electrolytical material, the capital is built-up on the grizzly bar in blade front, the conductive ion that these materials produce can shield fraud and hold the grid transducing signal, the normal Presentation Function of digimatic calipers was lost efficacy and causes and can not normally use.Therefore, although common digital display calliper introduced 30 to the market surplus year, domestic and international most of enterprises still are unwilling to use, and still prolong vernier caliper not high with precision, inefficiency.
In recent years, though the waterproof type electronic digital display calliper that adopts novel sensing principle (as magnetic induction sensor) to make is arranged on the market, because of its price height (being that common digital display calliper is more than 5 times) can not be popularized in the production scene and use.
(3) content of the present invention:
At the weak point of above-mentioned digimatic calipers, the purpose of this invention is to provide a kind of with the positive mechanical protection electronic digital display calipers of effectively isolating of blade with user's palm.
Can realize the mechanical protection electronic digital display calipers of above-mentioned purpose, comprise blade and the chi frame that is slidingly fitted on the blade, different is in the blade front shielded frame to be set.
Described shielded frame can have multiple mechanical structure form, wherein a kind of structure is connected and composed by railing or cover cap and bearing, bearing is loaded on the blade, railing or cover cap (removable or non-disconnectable) are connected on the bearing, the positive space that forms of railing or cover cap and blade effectively keeps apart railing or cover cap and blade front.
Palm grip railing or the cover cap and the blade back side during use, because railing or cover cap are kept apart palm and blade front, thereby prevent that the electrolyte substance such as sweat, cutting fluid on the palm is built-up on the grizzly bar in blade front, avoided the digimatic calipers Presentation Function to lose efficacy, guaranteed that it can normally use in the production scene.
Two bearings of general use in the said structure have maximum amount of movement for making the chi frame, and two bearings are located at blade two respectively, and cover cap or at least one railing place between two bearings.
For making things convenient for reading, cover cap is selected transparent material for use, perhaps selects the opacity material for use and offers the reading window thereon.
For not hindering the normal of chi frame to move, the spatial altitude of railing or cover cap is greater than the chi frame.
Advantage of the present invention:
1, simple in structure, be convenient to produce in enormous quantities.
2, cost is low.The protective frame cost that is increased is less than 1/10th of the whole chi cost of ordinary electronic digital display calliper, and the user is acceptant, the popularity rate height.
3, reliable effect is safeguarded simple.Can break down hardly, even accessory is also changed in accidental damage easily.
4, significant.Solved the key issue that long-term puzzlement digimatic calipers can not be used for the production scene, digimatic calipers precision height, advantage that detection efficiency is high have thoroughly been brought into play, created condition for the vernier caliper that replaces low precision, poor efficiency, market outlook are wide, and economic benefit is fairly obvious.
(4) description of drawings:
Figure 1 shows that the structural representation of one embodiment of the present invention.
Fig. 2 is the vertical view of Fig. 1.
Figure number sign: 1, blade; 2, chi frame; 3, bearing; 4, railing.
(5) embodiment:
Mechanical protection electronic digital display calipers of the present invention comprises blade 1, chi frame 2 and is located at the shielded frame of the positive top of blade 1, as shown in Figure 1 and Figure 2.
In Fig. 1, Fig. 2, shielded frame is made of two bearings 3 and two railings 4 (solid hopkinson bar or hollow tubular), two bearings 3 are individually fixed in the two ends of blade 1, two railings 4 place between two bearings 3, assign in the pin-and-hole relative on bearing 3 termination of railing 4, the height of two railings 4 is provided with unanimity, and is higher than the width that distance between 2, two railings 4 of chi frame equals blade 1.
Can replace two railings 4 with cover cap, cover cap is parallel to blade 1 and places between two bearings 3, and the termination of cover cap is engaged in the cotter way relative on the bearing 3, and the height of cover cap is higher than chi frame 2, and the cover cap width equals the width of blade 1.
In the mechanical protection electronic digital display calipers of the present invention, blade 1 back side and shielded frame constitute the position of controlling of operator when using.
Claims (5)
1, mechanical protection electronic digital display calipers, comprise blade (1) and with the chi frame (2) that blade (1) is slidingly matched, it is characterized in that: being provided with in blade (1) front can be with palm and the isolated shielded frame of blade (1).
2, mechanical protection electronic digital display calipers according to claim 1, it is characterized in that: described shielded frame comprises bearing (3) and railing (4) or cover cap, bearing (3) is located on the blade (1), railing (4) or cover cap are by bearing (3) support and connection, and railing (4) or cover cap and blade (1) front form the space.
3, mechanical protection electronic digital display calipers according to claim 2 is characterized in that: described bearing (3) is two, is located at blade (1) two respectively, and cover cap or at least one railing (4) are connected between two bearings (3).
4, mechanical protection electronic digital display calipers according to claim 3 is characterized in that: described cover cap is a transparent material, perhaps for offering the opaque material of reading window.
5, according to any one described mechanical protection electronic digital display calipers in the claim 2～4, it is characterized in that: the spatial altitude of described railing (4) or cover cap is greater than chi frame (2).
