Description
Technical field
The present invention relates to a kind of safety plate pull-out test instrument.
Background technology
Car insurance sheet is also known as automobile inserted sheet electric fuse, and insert type fuse can be divided into: extra small inserted sheet electric fuse, small size automobile fuse, medium size automobile fuse, large size automobile fuse, effect is protection circuit (circuit) and electrical equipment.
Safety plate is plugged on automobile, so after safety plate molding, need safety plate carries out plug test, and in reality production, be all some more large-scale equipment for what test, not only acquisition cost is higher, and compare occupation of land side, use all cumbersome, it is not easy to moved every time, place to use is more fixing, and the cost of maintaining is also higher.
Summary of the invention
The technical problem to be solved in the present invention is: in order to overcome the deficiencies in the prior art, it is provided that a kind of simple in construction, cost of manufacture is low, easy to use and flexible, and the safety plate pull-out test instrument that floor space is little.
The technical solution adopted for the present invention to solve the technical problems is: a kind of safety plate pull-out test instrument, including top board, clamp assemblies, stress assembly and counterweight, described clamp assemblies is fixed on below top board, described clamp assemblies includes two the symmetrical fixtures in left and right, the opposite face of described two fixtures is equipped with clamping part, described clamping part offers the groove that the plastic part surface with safety plate top matches, described two fixtures connect by the first bolt is fixing, described stress assembly is arranged on below clamp assemblies, described stress assembly includes two pieces of force blocks being hinged, the locating piece that the top of the opposite face of described two force blocks is provided with and space between two pins of safety plate bottom matches, two force block lower ends are provided with the second bolt, described counterweight is hung on the second bolt.
Installing in order to convenient, described top board offers chute, described clamp top is provided with and matches with chute
Slide block, fixture and top board are slidably connected.
In order to increase frictional force, it is prevented that stress assembly drops, the locating piece surrounding of described two force blocks has concaveconvex structure.
The invention has the beneficial effects as follows: body encapsulation and the pin of safety plate are fixed respectively by this safety plate pull-out test instrument by clamp assemblies and stress assembly, carry out pull-out test by counterweight, not only deft design, and cost of manufacture is low, floor space is little, uses and is convenient to flexibly.

In figure: 1. top board, 2. fixture, 3. the first bolt, 4. force block, 5. the second bolt, 6. counterweight, 7. locating piece, 8. chute, 9. slide block, 10. safety plate.
Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, and the basic structure of the present invention is only described in a schematic way, and therefore it only shows the composition relevant with the present invention.
As shown in Figures 1 to 3, a kind of safety plate pull-out test instrument of the present invention, including top board 1, clamp assemblies, stress assembly and counterweight 6, described clamp assemblies is fixed on below top board 1, described clamp assemblies includes two the symmetrical fixtures 2 in left and right, the opposite face of described two fixtures 2 is equipped with clamping part, described clamping part offers the groove that the plastic part surface with safety plate 10 top matches, described two fixtures 2 connect by the first bolt 3 is fixing, described stress assembly is arranged on below clamp assemblies, described stress assembly includes two pieces of force blocks being hinged 4, the locating piece 7 that the top of the opposite face of described two force blocks 4 is provided with and space between two pins of safety plate 10 bottom matches, locating piece 7 surrounding of described two force blocks 4 has the concaveconvex structure of strip.Two force block 4 lower ends are provided with the second bolt 5, and described counterweight 6 is hung on the second bolt 5.
Offering chute 8 on described top board 1, one of fixture 2 top in two pieces of fixtures 2 is provided with the slide block 9 matched with chute 8, and this fixture 2 is slidably connected with top board 1.
Need safety plate 10 is tested, then the Plastic Package position on safety plate 10 top be fixed on the holding position of two fixtures 2 because the encapsulation of safety plate 10 to be afterbody big, middle part is slightly narrow.It practice, all offer, on the relative face of two fixtures, the circular hole mated with the first bolt 3, two fixtures 3, through two circular holes, are then clamped, thus being clamped by safety plate 10 by the first bolt 3.nullThe Main Function of stress assembly is the metal pins clamping safety plate 10 bottom，Because the spacing of two metal pins of safety plate 10 is less at two pin mouths，So arranging locating piece 7 between two force blocks 4 of stress assembly，Locating piece 7 mates space bigger between two metal pins，Metal pins just can be made to block，Thus being fixed between two force blocks 4，Actually，The lower end of two force blocks 4 is arc，And two arc be that concave surface is relative，Two cambered surfaces all offer the circular hole mated with the second bolt 5，Two force blocks 4 are clamped by the second bolt 5，Because two force blocks 4 are hinged，Namely two force blocks 4 can rotate along reticule，Clamp by the metal pin of safety plate 10，Then on the second bolt 5, hang up the counterweight 6 of corresponding weight，Can be achieved with the test to safety plate 10 drawing holding capacity.
Compared with prior art, body encapsulation and the pin of safety plate 10 are fixed respectively by this safety plate pull-out test instrument by clamp assemblies and stress assembly, carry out pull-out test by counterweight 6, not only deft design, and cost of manufacture is low, floor space is little, uses and is convenient to flexibly.
With the above-mentioned desirable embodiment according to the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not necessarily departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content in description, it is necessary to determine its technical scope according to right.
