Description

Safety plate pull-out test instrument
Technical field
The utility model relates to a kind of safety plate pull-out test instrument.
Background technology
Car insurance sheet is also known as automobile inserted sheet fuse, and insert type fuse can be divided into: extra small inserted sheet fuse, small size automobile fuse, medium size automobile fuse, large size automobile fuse, and effect is protection circuit (circuit) and consumer.
Safety plate is plugged on automobile, so after safety plate is shaping, need to carry out plug test to safety plate, and in reality production, what be used for test is all that some are than relatively large equipment, not only acquisition cost is higher, and compare occupation of land side, use all cumbersome at every turn, be not easy to be moved, place to use is more fixing, and the cost of maintaining is also higher.
Utility model content
The technical problems to be solved in the utility model is: in order to overcome the deficiencies in the prior art, and provide a kind of structure simple, cost of manufacture is low, easy to use and flexible, and the safety plate pull-out test instrument that floor area is little.
The utility model solves the technical scheme that its technical matters adopts: a kind of safety plate pull-out test instrument, comprise top board, clamp assemblies, stressed assembly and counterweight, described clamp assemblies is fixed on below top board, described clamp assemblies comprises the symmetrical fixture in two, left and right, the opposite face of described two fixtures is equipped with clamping part, described clamping part offers the groove matched with the plastic part surface on safety plate top, described two fixtures are fixedly connected with by the first bolt, described stressed assembly is arranged on below clamp assemblies, described stressed assembly comprises two pieces of force blocks be hinged, the top of the opposite face of described two force blocks be provided with and safety plate bottom two pins between the locating piece that matches of space, two force block lower ends are provided with the second bolt, described counterweight is hung on the second bolt.
Conveniently install, 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 friction force, prevent stressed assembly from dropping, the locating piece surrounding of described two force blocks has concaveconvex structure.
The beneficial effects of the utility model are: this safety plate pull-out test instrument is fixed the body encapsulation of safety plate and pin respectively by clamp assemblies and stressed assembly, pull-out test is carried out by counterweight, not only deft design, and cost of manufacture is low, floor area is little, uses also flexibly very convenient.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of the utility model safety plate pull-out test instrument.
Fig. 2 is the structural representation of the utility model safety plate pull-out test instrument.
Fig. 3 is the explosive view of the utility model safety plate pull-out test instrument.
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.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figures 1 to 3, a kind of safety plate pull-out test instrument of the present utility model, comprise top board 1, clamp assemblies, stressed assembly and counterweight 6, described clamp assemblies is fixed on below top board 1, described clamp assemblies comprises the symmetrical fixture 2 in two, left and right, the opposite face of described two fixtures 2 is equipped with clamping part, described clamping part offers the groove matched with the plastic part surface on safety plate 10 top, described two fixtures 2 are fixedly connected with by the first bolt 3, described stressed assembly is arranged on below clamp assemblies, described stressed assembly comprises two pieces of force blocks be hinged 4, the top of the opposite face of described two force blocks 4 be provided with and safety plate 10 bottom two pins between the locating piece 7 that matches of space, 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.
Described top board 1 offers chute 8, and wherein one piece 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 to test safety plate 10, then the plastic package position on safety plate 10 top be fixed on clamping place of two fixtures 2 because the encapsulation of safety plate 10 to be afterbodys large, middle part is slightly narrow.In fact, the face that two fixtures are relative all offers the circular hole mated with the first bolt 3, two fixtures 3, through two circular holes, then clamp, thus are clamped by safety plate 10 by the first bolt 3.The Main Function of stressed 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 arrange locating piece 7 between two force blocks 4 of stressed assembly, locating piece 7 mates space larger between two metal pins, metal pins just can be made to block, thus be fixed between two force blocks 4, in fact, the lower end of two force blocks 4 is arc, and two arcs is that concave surface is relative, two cambered surfaces all offer the circular hole mated with the second bolt 5, two force blocks 4 clamp by the second bolt 5, because two force blocks 4 are hinged, namely two force blocks 4 can rotate along cross spider, metal pin by safety plate 10 clamps, then on the second bolt 5, hang up the counterweight 6 of corresponding weight, just can realize the test to safety plate 10 drawing holding capacity.
Compared with prior art, this safety plate pull-out test instrument is fixed the body encapsulation of safety plate 10 and pin respectively by clamp assemblies and stressed assembly, carries out pull-out test by counterweight 6, not only deft design, and cost of manufacture is low, floor area is little, uses also flexibly very convenient.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on instructions, must determine its technical scope according to right.
