Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model protecting tube;
Fig. 2 is the using state figure of the utility model protecting tube;
Fig. 3 is that the A-A of Fig. 2 is to cutaway view;
Fig. 4 is the schematic cross-section of embodiment 2 protecting tube.
Embodiment
In figure: 1, easily sting top layer, 2, antipricking layer, 3, elasticity location internal layer, 4, elasticity retaining band, 5, test port, 6, binding post, L, retaining band root are to the air line distance of test port.
Embodiment 1
As can be seen from Figure 1, protecting tube body of the present utility model is hollow elongated tubular shape thing, and the annular tube wall of protecting tube is made up of three-layer insulated Rotating fields, is followed successively by easily thorn top layer 1, antipricking layer 2, elasticity location internal layer 3 from outside to inside;
Being positioned at protecting tube tube wall outermost easy thorn top layer 1 cross section is closed loop configuration; Be sleeved under using state on binding post and play insulating protection effect, this easily stings top layer and is made up of transparent plastics or plastic cement material; The test port that can pass through top layer and antipricking layer and internal layer during use observes binding post structure and suit situation.
The cross section of the elasticity location internal layer 3 of antipricking layer 2 and tube wall inboard is " C " shape structure, the sidewall of antipricking layer 2 and elasticity location internal layer 3 is equipped with the position corresponding longitudinal strip test port 5 overlapped mutually, according to different binding post and testing apparatus, the width of this test port 5 is 1.5 ~ 5mm, passes to facilitate test test pencil; The outer surface on described easy thorn top layer 1 and test port 5 corresponding section are provided with the tag line of entry of stab wound;
Antipricking layer 2 adopts bundle weave or sheet plastic to make, and during protecting tube suit binding post, plays a supporting role and can prevent tube wall from surprisingly being cut.
Be positioned at the elasticity location internal layer 3 of body innermost layer, the inwall of its test port both sides is provided with the elasticity retaining band 4 running through whole piece protecting tube;
The present embodiment is less than 16mm(overall dimension to be applicable to diameter) protecting tube of binding post, an elasticity retaining band is respectively established in these protecting tube internal layer test port both sides, article two, elasticity retaining band 4 is symmetrical centered by test port lays, and elasticity retaining band 4 be all positioned at internal layer 3 opening side, elasticity location 1/2nd circumferential inner walls on (namely elasticity retaining band 4 is all positioned at the half-circle area that cylindric internal layer has test port 5 side); After body suit binding post, this elasticity retaining band 4 and the internal layer generation deformation of elasticity location are fastened on cylinder and prevent from coming off; The height of elasticity retaining band 4 should be less than or equal to the air line distance of root (test port side) to test port 5 port of this retaining band, height≤the L(L of elasticity retaining band is the air line distance of retaining band root to test port as shown in Figure 1), to guarantee that elasticity retaining band 4 can not block test port 5 after falling down completely.
Elasticity location internal layer 3 and elasticity retaining band 4 use elasticity and the good silica gel material of deformation to make; The utility model shown in Fig. 2 ~ Fig. 3 in a state of use, protecting tube is sleeved on the binding post 6 of brace, elasticity location internal layer 3 and elasticity retaining band 4 produce convex-concave deformation with binding post outline shape, utilize self elastic packaging and clip on binding post 6 cylinder, prevent protecting tube accidental; Because elasticity retaining band 4 symmetry is laid in the both sides of elasticity location internal layer test port, therefore depress binding post 6 away from test port (in eccentric shape) on elasticity retaining band 4 top after suit, play safety effect.
When in overhaul of the equipments work, when needing to measure equipment, penetrate with the test pencil of the testing apparatuss such as the universal instrument entry of stab wound tag line along top layer, the most advanced and sophisticated strip test port by antipricking layer and elasticity location internal layer of test pencil passes, and the metal cartridge of conflict binding post 6 is measured, and measures simple to operation, effectively avoid the troublesome operation opening, wrap up tested binding post, guarantee that the electric binding post in flakes of whole maintenance process is in state of insulation all the time, protection effect is good, safe and reliable.
Embodiment 2
For the protecting tube that diameter is more than 16mm binding post, because caliber is comparatively thick, elasticity retaining band is set up in test port both sides.
The present embodiment difference from Example 1 is that internal layer 3 test port both sides, body elasticity location respectively arrange two elasticity retaining bands 4, sees Fig. 4; Retaining band is symmetrical centered by test port to be laid, and flexible retaining band be all positioned at 1/2nd circumference of internal layer test port side; Also can according to be suitable for binding post diameter and distinctive appearance structure, respectively set up Article 3 elasticity retaining band in internal layer 3 test port both sides, elasticity location and meet use needs, namely the test port both sides of internal layer respectively arrange three elasticity retaining bands.
The height of described each bar elasticity retaining band 4 is all less than or equal to the air line distance of the root of this elasticity retaining band self near test port side to test port 5 port.
The present embodiment other technologies feature is identical with embodiment 1.
The utility model structure is simple, and cost is low, and the protection body of elongated tubular is easy to carry, deposits; Model scene according to binding post during use intercepts suitable length, to electric joint pin Rapid Implementation insulating protection in flakes; Utilize the feature of the elasticity retaining internal layer natural resiliency deformation inside tube wall, same protecting tube is made to be applicable to the binding post of Multiple Type, increase the scope of application, also reusable, solve prior art protection method and implement the problems such as loaded down with trivial details, the operating time is long, protection effect is unstable, dismounting is inconvenient, the scope of application is less.
Finally should be noted that: above embodiment is not intended to limit for illustration of the technical solution of the utility model; those skilled in the art modifies to execution mode or carries out equivalent replacement to portion of techniques feature; and do not depart from the essence of technical solutions of the utility model, all should be encompassed within the utility model scope required for protection.
