Description
[technical field]
The utility model relates to a kind of nut drawing force test structure, particularly relates to a kind of nut drawing force test structure.
[background technology]
When production has the product of nut, usually can carry out the pulling capacity test of nut, to detect the firm degree of nut.
Currently used test structure sees also Fig. 1, and Fig. 1 illustrates the nut drawing force test structure schematic diagram into prior art, and described structure has pull bar 100, and the one end has drawing hole 101, and the other end has test screw 102.
Please in conjunction with consulting Fig. 2, Fig. 2 illustrates the nut drawing force test structure application schematic diagram into prior art.Described test screw 102 is fixed in the nut 104 of product 103, described drawing hole 101 1 ends are hooked by spring balance 105 and carry out the pulling capacity test.
Yet, adopt said structure can have following shortcoming, when described nut 104 diameters hour, then described test screw 102 corresponds to small diameter, described test screw 102 processing difficulties (are for example worked as for below the M2.5, also be that diameter is during less than 2.5mm), and easy loss when test, because described structure is structure as a whole, cost of idleness is high after damaging, and described structure is and described nut 104 models structure one to one, and is therefore can not one multiplex, bad adaptability.
In view of this, be necessary to develop a kind of nut drawing force test structure in fact, to address the above problem.
[summary of the invention]
Therefore, the purpose of this utility model provides a kind of nut drawing force test structure, solves existing structure processing difficulties, fragile, and damages the problem that cost is high, application is single.
In order to achieve the above object, the nut drawing force test structure that the utility model provides, this structure comprises:
Pull bar, the one end has the drawing hole;
Be connected and fixed bar, the one end is fixed in described pull bar away from described drawing hole one end, and described being connected and fixed has external thread on the bar;
Abutment sleeve, one end have the internal thread that extends in it, and described screw-internal thread fit is fixed the described described external thread that is connected and fixed on the bar, and the described abutment sleeve other end has hanging platform;
Screw, it has thread and screw terminal, and described screw is located in the described abutment sleeve, and described thread has hanging platform one end by described abutment sleeve and exposes, and described screw terminal is subject to described hanging platform, and described thread cooperates with described nut shape.
Optionally, described pull bar has fixedly internal thread away from described drawing hole one end, is fixed with the described external thread that is connected and fixed bar.
Optionally, described pull bar and describedly be connected and fixed the structure that bar is formed in one.
Optionally, described pull bar is radially offered and penetrated in described drawing hole along described pull bar.
Optionally, the thread diameter of described screw is less than 2.5 millimeters.
Compared to prior art, utilize nut drawing force test structure of the present utility model, when using, described screw is inserted in the described abutment sleeve, again with describedly be connected and fixed the fixing described pull bar of bar one end, the other end screws in described abutment sleeve, so that described screw is compacted, and the screw terminal of described screw is stopped by described hanging platform, described thread is exposed by described abutment sleeve, again described thread is fixed in described nut, application of force drawing is carried out in described drawing hole to described pull bar, and then reaches the purpose of pull-out test.Because what be used for being fixed with described nut is the screw of commonly using, therefore processing is simple, and other element and described screw are separate element, after damaging, therefore described screw easily changes, cost is low, again owing to can reach by changing described screw the test of the nut that is applied to different-diameter, so range of application is wider.

[embodiment]
Please jointly consult Fig. 3-Fig. 5, Fig. 3 illustrates and is nut drawing force test structure one preferred embodiment schematic diagram of the present utility model, nut drawing force test structure of the present utility model one preferred embodiment decomposing schematic representation, nut drawing force test structure one preferred embodiment of the present utility model application schematic diagram.
In order to achieve the above object, the nut drawing force test structure that the utility model provides in the present embodiment, is used for the nut 209 on the test products 210, and this structure comprises:
Pull bar 200, the one end has drawing hole 201;
Be connected and fixed bar 202, the one end is fixed in described pull bar 200 away from described drawing hole 201 1 ends, and described being connected and fixed on the bar 202 has external thread;
Screw, it has thread 207 and screw terminal 208, and described screw is located in the described abutment sleeve 203, and described thread 207 has hanging platform 205 1 ends by described abutment sleeve 203 and exposes, described screw terminal 208 is subject to described hanging platform 205, described thread 207 and described nut 209 form fit.
