Detailed Description

The present invention is further described with reference to the following drawings and examples, which are not intended to limit the scope of the present invention.

In the present invention, words indicating directions, such as "front", "rear", "left", "right", "up", "down", etc., are used for convenience of describing the present invention according to the drawings, and are not intended to limit the scope of the present invention.

In order to solve the difficult problem of pasting of current resistance strain gauge, the utility model provides a portable resistance strain gauge pastes ware, it can paste resistance strain gauge evenly, firmly bridge surface, and its easy and simple to handle.

As shown in fig. 1-3, the portable resistance strain gauge sticker of the present invention includes a front plate 1, a rear plate 5, and a left side plate 6 and a right side plate 7 located between the front plate 1 and the rear plate 5.

The heights of the left side plate 6 and the right side plate 7 are smaller than the heights of the front side plate 1 and the rear side plate 5, so that a certain distance is reserved between the upper end and the lower end of the left side plate 6 and the upper end and the lower end of the right side plate 7 and between the upper end and the lower end of the front side plate 1 and the upper end and the lower end of the rear side plate 5.

An adhesive storage bin 9 with an opening at the upper end is also arranged between the left ends of the front side plate 1 and the rear side plate 5. The adhesive storage bin 9 is used for storing adhesive for adhering the resistance strain gauge.

Preferably, the lower surface of the adhesive reserve tank 9 is flush with the lower surfaces of the front and

rear side plates

1 and 5.

And a resistance strain gauge inlet 12 is arranged between the lower end of the front side plate 1 and the upper end of the adhesive storage bin 9. A resistance strain gauge can be manually inserted over the adhesive reserve 9 through the resistance strain gauge inlet 12.

A first rubber pressing wheel 10 is arranged above the adhesive storage bin 9. The front end and the rear end of the first rubber pinch roller 10 can be respectively installed on the front side plate 1 and the rear side plate 5 through a first rotating shaft 2. Thereby enabling the first rubber press wheel 10 to rotate.

Because the resistance strain gauge is manually inserted between the first rubber pressing wheel 10 and the adhesive storage bin 9, the rotation of the first rubber pressing wheel 10 drives the resistance strain gauge to pass through the adhesive storage bin 9, so that the bottom surface of the resistance strain gauge is uniformly coated with the adhesive.

And a second rubber pressing wheel 11 is arranged on the right side of the adhesive storage bin 9. The front end and the rear end of the second rubber pinch roller 11 can be respectively installed on the front side plate 1 and the rear side plate 5 through a second rotating shaft 3. Thereby, the second rubber press wheel 11 is enabled to rotate.

Preferably, the lowest end of the second rubber pressing wheel 11 is flush with the lower surfaces of the front side plate 1 and the rear side plate 5. Thus, when the portable electrical resistance strain gage applicator is placed on the surface of the bridge and pushed with force, the second rubber pinch roller 11 will rotate by virtue of the friction between it and the surface of the bridge.

In this way, under the driving of the first rubber pressing wheel 10, after the resistance strain gauge is uniformly coated with the adhesive on the bottom surface, the resistance strain gauge continues to advance and enters under the second rubber pressing wheel 11, so that the resistance strain gauge can be pressed on the surface of the beam body by the rotation of the second rubber pressing wheel 11, and the adhesion of the resistance strain gauge is realized.

The utility model discloses in, second rubber pinch roller 11 still is used for driving first rubber pinch roller 10 rotates.

For example, as shown in fig. 2 and 3, the first rubber pressing wheel 10 and the second rubber pressing wheel 11 are disposed adjacent to each other such that the rotation of the second rubber pressing wheel 11 can drive the first rubber pressing wheel 10 to rotate.

In the present invention, preferably, the portable resistance strain gauge sticker is further located on the compacting plate 8 between the front side plate 1 and the rear side plate 5. The compacting plate 8 is located above the first rubber pinch roller 10 and the second rubber pinch roller 11 and is used for compacting the first rubber pinch roller 10 and the second rubber pinch roller 11. The first rubber pressing wheel 10 and the second rubber pressing wheel 11 are pressed by the compacting plate 8, so that the first rubber pressing wheel 10 and the second rubber pressing wheel 11 can better act on the resistance strain gauge, the resistance strain gauge can be stretched flatly better, and the resistance strain gauge can be better driven to advance.

More preferably, an elastic mechanism is arranged between the compacting plate 8 and the left and

right side plates

6 and 7.

For example, the elastic mechanism includes a first spring 13 and a second spring 14. The first spring 13 is provided between the lower side of the compression plate 8 and the upper end of the left side plate 6. The second spring 14 is provided between the lower side of the compression plate 9 and the upper end of the right side plate 7.

Thus, as shown in fig. 2, in a normal state, that is, a non-operating state, the compression plate 8 does not press the first and

second rubber rollers

10 and 11 by the first and

second springs

13 and 14. As shown in fig. 3, in the operating state, by pressing the compacting plate 8, the elastic force of the first springs 13 and the second springs 14 is overcome, so that the compacting plate 8 can press on the first rubber pinch roller 10 and the second rubber pinch roller 11, thereby achieving flattening of the resistance strain gauge and further driving the resistance strain gauge to advance.

More preferably, the top of the compacting plate 8 is further provided with a pressing button 4. By means of the press button 4, pressing of the compacting plate 8 is facilitated.

As shown in fig. 4 to 6, in this embodiment, the second rubber pressing wheel 11 rotates the first rubber pressing wheel 10 by belt drive, unlike the first embodiment.

Wherein, a first belt pulley 15 is arranged on the first rotating shaft 2. And a second belt pulley 16 is arranged on the second rotating shaft 3. The first belt pulley 15 and the second belt pulley 16 are sleeved with a driving belt 17. Thus, the rotation of the second rubber pressing wheel 11 will drive the first rubber pressing wheel 10 to rotate through the driving belt 17.

The utility model discloses a portable resistance foil gage affixer can stretch flat resistance foil gage through first rubber pinch roller and second rubber pinch roller and make it keep leveling not curling pasting the in-process. Moreover, the adhesive can be automatically coated on the bottom surface of the resistance strain gauge through the first rubber pressing wheel and the adhesive storage bin, and the coating is uniform. Meanwhile, the resistance strain gauge is compacted by the second rubber pinch roller, so that the resistance strain gauge can be tightly attached.

The above embodiments of the present invention are merely examples for clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. It is not exhaustive here for all embodiments. All obvious changes or variations led out by the technical scheme of the utility model are still in the protection scope of the utility model.
