[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Of course, the specific embodiments described herein are only for explaining this utility model and are not intended to limit it.

[0017] It should be noted that, without conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0018] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] Example 1 See Figures 1 to 5 This utility model provides a concrete rebound detection area drawing device, including a gate-shaped frame 1, two guide cylinders 2 are fixedly installed on the horizontal crossbar 11 of the gate-shaped frame 1, and a sliding guide rod 3 is slidably installed in each guide cylinder 2. The lower end of the sliding guide rod 3 is fixedly connected to a stamp template 4 with a detection area graphic 41. Each sliding guide rod 3 is fitted with a spring 5 on its outer side. The upper and lower ends of the spring 5 are connected to the top of the sliding guide rod 3 and the horizontal crossbar 11, respectively. When the spring 5 is not in operation, it drives the sliding guide rod 3 to move upward and reset through elastic force, so that the stamp template 4 is suspended in the air and keeps a certain distance from the ground, avoiding wear or contamination caused by the stamp template 4 accidentally contacting the ground. A support crossbar 13 is fixedly installed at the bottom of the two uprights 12 of the portal frame 1. The support crossbar 13 is provided with an overlapping groove 6 for placing the inkpad box 7.

[0021] The upper ends of the two sliding guide rods 3 are fixedly connected by pressing crossbar 31.

[0022] Move the entire device to the concrete testing area, hold the pressing bar 31 and apply downward pressure to drive the two sliding guide rods 3 to slide synchronously in the guide cylinder 2, so that the stamp template 4 is in close contact with the concrete surface, and the stamp template 4 imprints the standard test area pattern 41 on the concrete surface.

[0023] The pre-made detection area graphic 41 using the stamp template 4 allows for the precise printing of a rebound detection area that meets the specifications in one go, eliminating errors from manual scribing, improving the reliability of detection data, and increasing construction efficiency compared to manual scribing.

[0024] A reinforcing rod 42 is provided between the stamp template 4 and the sliding guide rod 3.

[0025] The inkpad box 7 is equipped with an absorbent inkpad cotton 71, and protrusions 72 are fixedly provided on both sides of the inkpad box. The protrusions 72 are movably placed in the overlapping groove 6.

[0026] Align the protrusions 72 on both sides of the inkpad 7 with the overlapping grooves 6 on the support crossbar 12 of the portal frame 1, and push them horizontally until they are fully engaged, ensuring that the inkpad 7 is stably placed directly below the stamp template 4. Hold the pressing bar 31 and apply downward pressure to drive the two sliding guide rods 3 to slide synchronously in the guide cylinder 2, so that the stamp template 4 descends into the inkpad box 7, and the inkpad cotton 71 absorbs the ink evenly.

[0027] A handle 73 is provided at each of the two ends of the inkpad box 7.

[0028] The inkpad 7 can be lifted upward by the handle 73, which makes it easy for the user to draw on the concrete rebound test area. If the drawn pattern is not clear, the inkpad 7 can be placed in the overlap groove so that the inkpad can be absorbed on the stamp template 4.

[0029] When using this utility model, the entire device is moved to the concrete testing area, and the pressing bar 31 is held and pressed down to drive the two sliding guide rods 3 to slide synchronously in the guide cylinder 2, so that the stamp template 4 is in close contact with the concrete surface, and the stamp template 4 imprints the standard test area pattern 41 on the concrete surface.

[0030] The pre-made detection area graphic 41 using the stamp template 4 allows for the precise printing of a rebound detection area that meets the specifications in one go, eliminating errors from manual scribing, improving the reliability of detection data, and increasing construction efficiency compared to manual scribing.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
