Abstract
The utility model discloses a mechanism locking a testing nib for a clicking and scribing experimental machine. The mechanism includes a fixing bracket, a testing nib bracket penetrates the fixing bracket, and a weight pallet is fixed at the top of the testing nib bracket and locked with the fixing bracket through a locking piece. The mechanism realizes the locking of the testing nib and the fixing bracket, and completely prevents the testing nib from having adverse conditions like rotation during a test.
Description
Technical field
The utility model relates to a kind of click line experimental machine, particularly relates to a kind of test nib locking mechanism of clicking the line experimental machine.
Background technology
In existing click line experimental machine, the locking mechanism of test nib as shown in Figure 1, test pen head bracket 2 ' is arranged in the fixed support 1 ', test nib 3 ' is fixedly arranged on the bottom of test pen head bracket 2 ', and the top of test pen head bracket 2 ' also is provided with a weight tray 4 ', is used to place counterweight 5 ' to pressurize to testing nib 3 '.But, because test pen head bracket 2 ' only is arranged in the fixed support 1 ', at test pen head bracket 2 ' with A-A ' direction (as shown in Figure 1) be axis with respect to the rotation of fixed support 1 ' then without any the inhibition means.Therefore, when clicking the work of line experimental machine, above-mentioned rotation can take place in not timing ground in test pen head bracket 2 ', and because test nib 3 ' is fixedly arranged in the test pen head bracket 2 ', thereby cause in test is carried out, test nib 3 ' also can be ensued rotation, easily damage is brought on the surface of specimen, influences precision of test result.
Summary of the invention
The technical problems to be solved in the utility model is in order to overcome the defective that the test nib rotates easily in the prior art, the test nib locking mechanism that provides a kind of click that can avoid the test pen hair to give birth to rotation to rule experimental machine.
The utility model solves above-mentioned technical matters by following technical proposals:
A kind of test nib locking mechanism of clicking the line experimental machine, it comprises a fixed support, is equipped with a test pen head bracket in this fixed support, and the top of this test pen head bracket is installed with a weight tray, its characteristics are that this weight tray and this fixed support lock mutually by a locking piece.
Preferably, this locking piece is a single-head screw, this weight tray downside is provided with first perforate with internal thread, the externally threaded end that has of this single-head screw revolves adaptedly and is located in this first perforate, the position that this is support bracket fastened to be positioned under this first perforate is provided with one second perforate, and the externally threaded end that do not have of this single-head screw is inserted in this second perforate adaptedly.
Positive progressive effect of the present utility model is: by a locking piece weight tray and fixed support are locked mutually, and because weight tray is the top that is fixedly arranged on the test pen head bracket, and the test nib is fixedly arranged in the test pen head bracket, thereby just realized the locking between test nib and the fixed support, the rough sledding of having avoided the test nib in test is carried out, to rotate up hill and dale, reduce even eliminated of the damage of test nib, guaranteed precision of test result test sample surface.
Description of drawings
Fig. 1 is the structural representation of the test nib locking mechanism of existing click line experimental machine.
Fig. 2 is the structural representation of the test nib locking mechanism of click line experimental machine of the present utility model.
Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As shown in Figure 2, the test nib locking mechanism of click line experimental machine of the present utility model comprises a fixed support 1, be equipped with a test pen head bracket 2 in this fixed support 1, the bottom of this test pen head bracket 2 is installed with a test nib 3, the top of this test pen head bracket 2 is installed with one and is used to place the weight tray 4 of compression weight 5, especially, this weight tray 4 locks by a locking piece mutually with this fixed support 1.
Still as shown in Figure 2, this locking piece can select to adopt a single-head screw 6, correspondingly, at these weight tray 4 downsides the one first perforate (not shown) with internal thread is set, so that the externally threaded end that has of this single-head screw 6 revolves adaptedly and is located in this first perforate, in addition, in the position that is positioned under this first perforate of this fixed support 1 one second perforate 7 is set, so that the externally threaded end that do not have of this single-head screw 6 is inserted in this second perforate 7 adaptedly.Design by this single-head screw 6, make and lock mutually between weight tray 4 and the fixed support 1, and because weight tray 4 is the tops that are fixedly arranged on test pen head bracket 2, and test nib 3 is fixedly arranged in the test pen head bracket 2, thereby just realized the locking between test nib 3 and the fixed support 1, the rough sledding of having avoided the test nib in test is carried out, to rotate up hill and dale, reduce even eliminated of the damage of test nib, guaranteed precision of test result test sample surface.
Though more than described embodiment of the present utility model, but those skilled in the art is to be understood that, these only illustrate, and under the prerequisite that does not deviate from principle of the present utility model and essence, can make numerous variations or modification to these embodiments.Therefore, protection domain of the present utility model is limited by appended claims.
Claims (2)
1. test nib locking mechanism of clicking the line experimental machine, it comprises a fixed support, be equipped with a test pen head bracket in this fixed support, the top of this test pen head bracket is installed with a weight tray, it is characterized in that this weight tray and this fixed support lock mutually by a locking piece.
2. the test nib locking mechanism of click line experimental machine as claimed in claim 1, it is characterized in that, this locking piece is a single-head screw, this weight tray downside is provided with first perforate with internal thread, the externally threaded end that has of this single-head screw revolves adaptedly and is located in this first perforate, the position that this is support bracket fastened to be positioned under this first perforate is provided with one second perforate, and the externally threaded end that do not have of this single-head screw is inserted in this second perforate adaptedly.
