TECHNICAL FIELD

[0001] The utility model relates to the technical field of line marker, concretely is concrete rebound test area line marker. BACKGROUND

[0002] The rebound method detects the concrete strength and cannot leave the measurement area selection, and the measurement points are evenly distributed in the measurement area range, and the net distance of adjacent two measurement points is not less than 20mm. The measurement area must be clear and meet the specification requirements. The measurement area arrangement of the rebound method for detecting the concrete strength is currently manually wall surface marking, and the measurement area is selected and rebounded according to the measurement area. At this time, manual selection and drawing of the measurement area cause great waste of manpower and material resources, and the detection efficiency needs to be improved. At present, the concrete strength on-site detection has many problems such as lack of equipment, simple measurement area marking and inconvenience. Therefore, at present, an operationally convenient and simply installed concrete strength measurement area marking device is urgently needed to save energy and detection time, effectively improve the detection efficiency and promote the scientification, standardization and systematization of the concrete strength detection. SUMMARY

[0003] In view of the above problems, the utility model provides a concrete rebound test area line marker to solve the problems in the background art.

[0004] To achieve the above object, the utility model provides the following technical scheme: a concrete rebound test area line marker, comprising a spray gun, a sealing cover connected with the nozzle of the spray gun, and a template provided at the tail end of the sealing cover, wherein the template is movably connected with the sealing cover.

[0005] The sealing cover comprises a first opening connected with the nozzle and a second opening connected with the template, wherein both sides of the second opening are provided with clamping grooves, the template is inserted with the sealing cover through the clamping grooves, and the shape and size of the template are the same as those of the second opening.

[0006] Further, the sealing cover is in the shape of a pyramid, the first opening is provided with an internal thread for threaded connection with the nozzle.

[0007] Further, the liquid sprayed from the nozzle can completely cover the second opening.

[0008] Further, any side wall of the sealing cover close to the second opening is provided with a liquid outlet, and the lower end of the liquid outlet is connected with a liquid storage box.

[0009] Further, an inclined surface is arranged between the liquid outlet and the liquid storage box.

[0010] Further, the liquid storage box is provided with a water-absorbing sponge.

[0011] Compared with the prior art, the utility model has the advantages of:

[0012] This invention features rapid spraying, clear test area lines, eliminates the need for markers or stamps / ink, is lightweight and flexible in combination, saves energy and testing time, effectively improves testing efficiency, and enhances the reliability and accuracy of tests.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] Example 1:

[0019] Depend on Figure 1 As shown, the concrete rebound test area marking device includes a spray gun 1, a sealing cover 2 connected to the nozzle of the spray gun 1, and a template 3 provided at the end of the sealing cover 2. The template 3 is movably connected to the sealing cover 2.

[0020] The sealing cover 2 is pyramidal in shape, including a first opening 21 connected to the nozzle and a second opening 22 connected to the template 3. The second opening 22 is larger than the first opening 21. The first opening 21 has internal threads for threaded connection with the nozzle. The second opening 22 has slots 23 on both sides, through which the template 3 is inserted into the sealing cover 2. Different templates 3 can be replaced as needed, and the insertion design facilitates template replacement. The template 3 has the same shape and size as the second opening 22. The liquid sprayed from the nozzle can completely cover the second opening 22.

[0021] In use, connect the first opening 21 of the sealing cover 2 to the spray gun 1, insert the template 3 into the second opening 22 through the slot 23, place the template on the concrete wall to be marked, and after the spray gun 1 sprays the paint, the paint is sprayed onto the template 3 through the sealing cover 2 and onto the wall through the perforation of the template 3 to form a mark.

[0022] Example 2:

[0023] Depend on Figure 2 As shown, the similarities between this embodiment and Embodiment 1 will not be repeated here. The difference is that: a liquid outlet 4 is provided on either side wall of the sealing cover 2 near the second opening 22, and a liquid storage box 5 is connected to the lower end of the liquid outlet 4. An inclined surface 6 is provided between the liquid outlet 4 and the liquid storage box 5. An absorbent sponge 7 is provided inside the liquid storage box 5.

[0024] After the paint sprayed from the spray gun 1 passes through the template 3, the excess paint will flow down the template 3, through the inclined surface 6 into the liquid collection box 5, where it will be absorbed by the water-absorbing sponge 7, thus preventing contamination of the concrete wall surface and making the painted lines clearer.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
