Abstract
Handcart switch cabinet insertion depth measuring appliance.Provide a kind of structure simple, can Quick Measurement the little handcart switch cabinet insertion depth measuring appliance of measuring error, comprise urceolus and push rod, described push rod can fit in described urceolus, and described outer tube rear end is provided with position limiting convex ring; Described push rod front end is provided with groove, and in described groove, adaptation has rubber band, and the external diameter of rubber band is consistent with urceolus internal diameter, and described putting back-end is provided with draw ring.Described push rod is provided with scale.Described putting back-end is also provided with threaded hole.The utility model structure is simple, after only urceolus need being put into handcart, promote push rod, namely the distance that push rod enters handcart is the degree of depth that handcart moving contact inserts static contact, convert not visible insertion depth to can be push rod and push the degree of depth, be marked with scale at push rod, directly can read and push distance, and ruler measurement need not be re-used, simple and fast.
Description
Technical field
The utility model relates to transformer station's handcart switch cabinet, is specifically related to a kind of handcart switch cabinet insertion depth measuring appliance.
Background technology
Handcart switch cabinet has the advantages such as volume is little, lightweight, cabinet outward appearance neat appearance, cabinet body structure is compact, floor area is little.But in use there is maximum deficiency is exactly: whether dynamic and static contact contraposition accurately cannot monitor.It is crucial that the dynamic and static contact of hands injured effectively contacts, if moving contact insertion depth not and virtual connection is touched, will cause contact temperature too high, cause surface oxidation to accelerate aggravation contact resistance again to increase, circulation like this, finally causes arcing, even blasts to cause fire to cause losing on a large scale.So handcart insertion depth is the basis ensureing dynamic and static contact reliable contacts.
Patent name is " a kind of Method and kit for detecting handcart switch cabinet insertion depth ", application number is the Chinese patent of " 201410262152.9 ", disclose a kind of Method and kit for detecting handcart switch cabinet insertion depth, the method first need measure the end of static contact (1) and the depth B of fixed contact pedestal (3) outer rim, chamfer contact point on moving contact (4) and the degree of depth R with moving contact (4) end, the degree of depth A of the end of the position after location-plate (2) is pushed and static contact (1), the degree of depth L of static contact (1) is inserted finally by the contact point calculating moving contact (4).The method step is complicated, and measuring speed is slow, and because what measure is length in not visible environment, poor accuracy.
Utility model content
For above-mentioned technical matters, the utility model provide a kind of structure simple, can Quick Measurement the little handcart switch cabinet insertion depth measuring appliance of measuring error.
The technical solution of the utility model is: comprise urceolus and push rod, and described push rod can fit in described urceolus, and described outer tube rear end is provided with position limiting convex ring; Described push rod front end is provided with groove, and in described groove, adaptation has rubber band, and the external diameter of rubber band is consistent with urceolus internal diameter, and described putting back-end is provided with draw ring.
Described push rod is provided with scale.
Described putting back-end is also provided with threaded hole.
The beneficial effects of the utility model are: measuring appliance structure is simple, after only urceolus need being put into handcart, promote push rod, namely the distance that push rod enters handcart is the degree of depth that handcart moving contact inserts static contact, convert not visible insertion depth to can be push rod and push the degree of depth, be marked with scale at push rod, directly can read and push distance, and ruler measurement need not be re-used, simple and fast.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model,
In figure, 1 is urceolus, and 11 is position limiting convex rings, and 2 is push rods, and 21 is draw rings, and 22 is grooves, and 23 is rubber bands, and 24 is threaded holes.
Embodiment
Below in conjunction with accompanying drawing, the utility model is illustrated.
As shown in Figure 1, handcart switch cabinet insertion depth measuring appliance, comprises urceolus 1 and push rod 2, and described push rod 2 can fit in described urceolus 1, is convenient to push rod 2 and moves in urceolus 1;
Described urceolus 1 rear end is provided with position limiting convex ring 11, can be fixed on handcart entrance;
Described push rod 2 front end is provided with groove 22, in described groove 22, adaptation has rubber band 23, the external diameter of rubber band 23 is consistent with urceolus 1 internal diameter, reach the object of push rod 2 smooth and easy motion in urceolus 1 whereby, enable the utility model be applicable to each electric substation simultaneously, and completely and fingertip close contact, the object reducing error can be reached;
Described push rod 2 rear end is provided with draw ring 21, facilitates staff to operate push rod 2.
Described push rod 2 is provided with scale, is convenient to directly read insertion depth, and does not need to use ruler measurement again, make measurement more quick.
Described push rod 2 rear end is also provided with threaded hole, is convenient for measuring device and extracts from fingertip.
During use, the utility model product is put into handcart entrance, the position limiting convex ring 11 of urceolus 1 makes urceolus be fixed on porch, and push till push rod 2 to push rod encounters moving contact, take reading, reading is handcart insertion depth L.
