Referring to fig. 1 to 10, an exterior wall paint scraper for construction, which is convenient to replace, comprises a handle 1 and a scraper 2.

As shown in fig. 1, the handle 1 includes a square plate structure at the front end and a long plate structure at the rear side to facilitate hand-held operation by a person.

The front end of the handle 1 is provided with a clamping groove 101; the clamping grooves 101 are arranged in parallel, go deep from the front end to the rear end and penetrate through the left side and the right side of the handle 1; the squeegee 2 is inserted into the holding groove 101.

The upper end surface of the handle 1 is provided with an elastic plate 3, and the front end part of the elastic plate 3 is elastically pressed on the upper surface of the scraper 2; the lower part of the rear end of the elastic plate 3 is provided with a locking component 4.

It can be understood that the front end of the elastic plate 3 provides a downward pressure to be in close contact with the squeegee 2; the rear end of the spring plate 3 provides downward pressure to depress the locking assembly 4.

In some embodiments, the spring plate 3 is pivotally connected to the handle 1.

Specifically, horizontal round rods 301 are arranged on two sides of the elastic plate 3, and the mounting seat plate 5 is arranged on the upper surface of the handle 1; each mounting seat plate 5 consists of two parallel perforated plates, and the horizontal round rod 301 is inserted into the mounting seat plate 5 to rotate.

Under the state that the scraper 2 is not installed at ordinary times, the front end of the elastic plate 3 is pressed downwards, and the height of the lower end face of the elastic plate is lower than the upper end face of the clamping groove 101; as shown in fig. 2 and 3.

At the same time, the locking assembly 4 is pressed and inserted downward into the clamping groove 101.

Thereby realizing synchronous pressure supply at the front end and the rear end in a daily state.

In some embodiments, the locking assembly 4 includes an insertion plate 401, a through square opening 402, a receptacle 403.

The insertion plate 401 is a planar plate structure and is fixedly connected to the lower portion of the elastic plate 3 near the rear end; the penetrating square opening 402 corresponds to the position of the inserting plate 401, is arranged on the handle 1 and penetrates into the clamping groove 101; the insertion hole 403 is provided in the squeegee 2 at a position corresponding to the position of the square-shaped opening 402.

It will be appreciated that for the through square 402, the socket 403 should be larger than the cross-section of the insert plate 401 to enable it to be inserted and lifted upwards.

That is, the front-to-back width of the insertion hole 403 should be greater than the front-to-back thickness of the insertion plate 401; the height of the insert plate 401 is greater than the depth of the through square opening 402.

Meanwhile, the left and right lengths of the through square opening 402 and the insertion hole 403 are matched with the left and right lengths of the insertion plate 401; in the use state, the left and right side surfaces of the insertion plate 401 are in sliding contact with the left and right inner walls of the through square opening 402 and the insertion hole 403, so that the squeegee 2 is locked in the left and right directions.

For the through square opening 402 and the insertion hole 403, the two can be set to be the same size; alternatively, the front and rear width of the insertion hole 403 may be smaller than the through square opening 402.

Please refer to fig. 3-7, which are schematic views illustrating the operation status of the installation scraper 2.

In this state, the insertion plate 401 penetrates downward through the through square opening 402 and is inserted into the insertion hole 403 by the pressure of the elastic plate 3.

Please refer to fig. 8-10, which are schematic views illustrating the unlocking state of the locking assembly 4.

The sliding and clamping of the vertical plate 201 and the vertical groove 102 limits the front and back movement of the scraper 2, and the matching locking component 4 completely limits the scraper 2.

When in use, the tail end of the elastic plate 3 is lifted from the left side or the right side of the handle 1, and the scraping plate 2 is inserted into the clamping groove 101; the vertical plate 201 is slidably clamped in the vertical groove 102; after the installation in place, the elastic plate 3 is loosened; in a natural state, the insertion plate 401 is snapped into the insertion hole 403.

Meanwhile, in the use process, the lower side of the front end of the scraper 2 is in contact with the wall surface, and the scraper 2 deforms upwards; the deformation can further press the vertical plate 201 through the elastic plate 3 to the rear end transfer part, and the stability is better ensured.

And, the elastic plate 3 providing the downward pressure can remarkably improve the bearing capacity of the scraper 2, enhance the durability and prolong the service life.

In some embodiments, two elastic plates 3 are provided, and the two elastic plates 3 are symmetrically provided at the upper end of the handle 1.

It is understood that one or two may be provided for the elastic plate 3; the operation is better under the state that one elastic plate 3 is arranged; in the state of setting up two elastic plates 3, stability and intensity are higher.

In some embodiments, the tail end of the elastic plate 3 is tilted upward to facilitate the operator to lift the tail end of the elastic plate 3 upward.

In some embodiments, the front end of the upper surface of the screed 2 is a ramp surface 202.

Preferably, the ramp surface 202 is in the form of an upwardly projecting arcuate surface.

In use, the front end of the blade 2 is inevitably worn gradually; the slope 202 is arranged so that the front end of the scraper 2 can be always kept in a pointed form during wear, thereby ensuring construction quality.

As shown in fig. 13; after the scraper blade 2 is used for a period of time, the lower end of the front side of the scraper blade is worn to form an inclined plane; the leading end of the ramp surface intersects the ramp surface 202 to form a point.

Referring to fig. 11 and 12, in some embodiments, the front end of the elastic plate 3 is provided with a downward-folding hook 302.

In match, the upper surface of the scraper 2 is provided with a groove 203, and the lower folding hook 302 is clamped in the groove 203; thus, the stability of the installation can be further ensured.

It is understood that the rear end of the lower hook 302 is in contact with the rear end surface of the groove 203 in the mounted state.

In the utility model, the scraper 2 which is installed in a sliding way realizes the quick replacement operation; the vertical plate 201 is clamped with the vertical groove 102 and matched with the locking component 4 to completely limit the scraper 2; the rear end of the elastic plate 3 is provided with a downward pressing locking assembly 4, so that unlocking can be realized by pulling up, and the elastic plate can be quickly and efficiently detached; the front end of the elastic plate 3 is provided with a downward-folded hook 302 matched with the groove 203, so that the stability of installation is further ensured; the deformation of the scraper 2 is transmitted to the rear end through the elastic plate 3, so that the vertical plate 201 can be further pressed down, and the stability is better ensured; the elastic plate 3 with downward pressure can obviously improve the bearing capacity of the scraper 2, enhance the durability and prolong the service life; the front end of the upper surface of the scraper blade 2 is a slope surface 202, and the front end of the scraper blade 2 is always kept in a tip form in abrasion, so that the construction quality is ensured.
