[0004] In response to the above-mentioned related content, it is believed that the following technical defects exist: in the process of using the concrete rebound tester to detect different positions of the wall in order to obtain the value of the wall position, it is found that when the angle between the detection head on the concrete rebound tester and the wall is offset, the tested value will have a large deviation from the accurate value. This also results in the need for workers to repeatedly judge whether there is a deviation between the detection head of the concrete rebound tester and the wall during the detection process using the concrete rebound tester, which also affects the efficiency of wall detection. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that when a concrete rebound tester is used to detect different positions of a wall to obtain the value of the wall position, it is found that when the angle between the detection head of the concrete rebound tester and the wall is offset, the tested value will have a large deviation from the accurate value, which also leads to the need for workers to repeatedly judge whether there is a deviation between the detection head of the concrete rebound tester and the wall during the detection process using the concrete rebound tester, which also leads to the disadvantage of affecting the efficiency of wall detection.

[0006] In order to solve the above technical problems, the utility model provides a concrete rebound tester, comprising: a rebound tester body, a detection head is installed at one end of the rebound tester body, a supporting device is provided on the arc surface of the rebound tester body, and the supporting device comprises a fixing ring, the fixing ring is fixedly connected to the rebound tester body, a side of the fixing ring close to the detection head is fixedly connected with a plurality of fixing blocks, a plurality of the fixing blocks are provided with the same connecting ring on a side close to the fixing ring, a plurality of connecting grooves are provided on a side of the connecting ring close to the fixing block, a plurality of the fixing blocks are respectively interference-connected with the plurality of connecting grooves, both ends of the arc surface of the connecting ring are fixedly connected with connecting blocks, an adjusting rod is slidably penetrated through the inner wall of the connecting block, a spring is sleeved on the arc surface of the adjusting rod, both ends of the spring are fixedly connected to the adjusting rod and the connecting block, respectively, and a same contact ring is fixedly connected to one end of the two adjusting rods away from the spring.

[0007] The effect achieved by the above components is: when using the detection head on the rebound tester body to test the wall, it is necessary to test the wall at different test points on the wall through the detection head, and finally remove the highest value and the three lowest values ​​of the three test points, and then find the average value of the remaining values ​​to complete the final detection value of the wall. However, in the process of testing different positions of the wall to obtain the value of the wall position, it is found that when the angle between the detection head and the wall is offset, the tested value will have a large deviation from the accurate value. This also leads to the need for workers to repeatedly judge whether there is a deviation between the detection head and the wall during the detection process, which will affect the efficiency of wall detection. Connect the connecting groove on the connecting ring and the connecting block on the fixing ring. After the connection is made, the connecting ring can be installed on the fixing ring. At this time, the detection head is used to contact the wall. The contact ring will contact the wall first. The worker only needs to fit the contact ring to the wall to avoid the deviation between the detection head on the rebound tester body and the wall. Press the rebound tester body, and the connecting rod slides in the connecting block, and moves with the rebound tester body, thereby driving the contact ring to move in the direction of the rebound tester body. At this time, the spring is in a stretched state, and the wall can be detected by the detection head. After the detection, the spring recovery will drive the connecting rod and the contact ring to move, so that the angle between the detection head and the wall can be adjusted by the support device next time.

The metal block installed on the fixing ring and the magnetic block installed on the connecting ring can guide the fixing block and the connecting groove to align through the magnetic force between the two before the fixing block and the connecting groove are connected, thereby improving the connection efficiency between the fixing block and the connecting groove.

[0010] Preferably, a plurality of contact blocks are fixedly connected to a side of the contact ring away from the adjusting rod, and the plurality of contact blocks are evenly distributed on the contact ring.

[0011] The effects achieved by the above components are: when the contact ring is used to contact the wall surface, the contact block installed on the contact ring can improve the stability of the connection between the contact ring and the wall, and the contact block can improve the use effect of the contact ring.

[0012] Preferably, the adjusting rod is a titanium alloy rod.

[0013] The effect achieved by the above components is that the surface of the adjusting rod made of titanium alloy is relatively hard, which also makes it difficult for the surface of the adjusting rod to deform after long-term use, and has a longer service life.

[0015] The effect achieved by the above components is: when using the rebound tester body to test the wall, it is found that there are many test points that need to be tested on the wall, which causes the workers to forget the test point positions when testing. At this time, the workers need to measure the same test point positions on the wall for a second time. The second test will waste a lot of time and affect the detection process. When detecting the monitoring point position of the wall, push the marker pen upward. The movement of the marker pen will drive the card block to slide out of the card slot. The limit ring is connected to the rebound tester body through a connecting rod, so that the marker pen can be taken out of the limit ring, and the marker pen can be used to mark the test points that have been tested, which can effectively avoid the situation of forgetting the test points.

[0016] Preferably, both end side walls of the slot are fixedly connected with elastic pads, and the cross-section of the elastic pads is rectangular.

[0017] The effect achieved by the above components is that when the card block contacts the card slot, the elastic pad installed in the card slot can improve the tightness of the connection between the card block and the card slot, thereby improving the stability of the marker pen in the limiting ring.

[0018] Preferably, a plurality of auxiliary blocks are fixedly connected to the arc surface of the marker pen, and the plurality of auxiliary blocks are evenly distributed on the arc surface of the marker pen.

[0019] The effect achieved by the above components is that when using a marker pen to mark the wall position that has been inspected, the auxiliary block installed on the marker pen can increase the friction between the hand and the marker pen body, thereby improving the efficiency of using the marker pen.

[0032] In the embodiments of the present invention, please refer to Figure 2 and Figure 3The supporting device 2 includes a fixing ring 201, which is fixedly connected to the rebound tester body 1. A side of the fixing ring 201 close to the detection head 4 is fixedly connected with a plurality of fixing blocks 202. A same connecting ring 203 is provided on a side of the fixing ring 201 close to the fixing block 202.

The plurality of fixing blocks 202 are respectively interference-connected with the plurality of connecting grooves 204. Both ends of the arc surface of the connecting ring 203 are fixedly connected with connecting blocks 205. An adjusting rod 206 is slidably penetrated through the inner wall of the connecting block 205. A spring 207 is sleeved on the arc surface of the adjusting rod 206. Both ends of the spring 207 are respectively fixedly connected with the adjusting rod 206 and the connecting block 205. The ends of the two adjustment rods 206 away from the spring 207 are fixedly connected to the same contact ring 208. When the detection head 4 on the rebound tester body 1 is used to test the wall, it is necessary to test the wall at different test points on the wall through the detection head 4, and finally remove the highest value and the three lowest values ​​of the three test points, and then calculate the average value of the remaining values ​​to complete the final detection value of the wall. However, in the process of testing different positions of the wall to obtain the value of the wall position, it is found that when the angle between the detection head 4 and the wall is offset, the tested value will have a large deviation from the accurate value. This also leads to the need for workers to repeatedly judge whether there is a deviation between the detection head 4 and the wall during the detection process. , which will affect the efficiency of wall detection. The connecting groove 204 on the connecting ring 203 is connected with the fixing block 202 on the fixing ring 201, and the connecting ring 203 can be installed on the fixing ring 201. At this time, the detection head 4 is used to contact the wall, and the contact ring 208 will contact the wall first. The worker only needs to fit the contact ring 208 with the wall to avoid the deviation between the detection head 4 on the rebound test body 1 and the wall. Press the rebound test body 1, and the adjustment rod 206 slides in the fixing block 202, and moves with the rebound test body 1, thereby driving the contact ring 208 to move in the direction of the rebound test body 1. At this time, the spring 207 is in a stretched state, and the wall can be detected through the detection head 4. After the detection, the spring 207 will restore and drive the adjustment rod 206 and the contact ring 208 to move, so that the angle between the detection head 4 and the wall can be adjusted by the support device 2 next time. The support device 2 can prevent the detection head 4 from deviating from the wall when in use, thereby affecting the detection value. The two ends of the side of the fixing ring 201 close to the fixing block 202 are fixedly connected with metal blocks 211, and the connecting ring 203 is fixedly connected with two magnetic blocks 210 on the side close to the fixing ring 201. The two magnetic blocks 210 are respectively adsorbed with the two metal blocks 211. When the fixing ring 201 is connected to the connecting ring 203, the fixing block 202 needs to be inserted into the connecting groove 204 before the connection between the fixing ring 201 and the connecting ring 203 can be completed.The metal block 211 installed on the fixing ring 201 and the magnetic block 210 installed on the connecting ring 203 can guide the fixing block 202 to align with the connecting groove 204 through the magnetic force between the two before the fixing block 202 and the connecting groove 204 are connected, which can improve the connection efficiency between the fixing block 202 and the connecting groove 204. A plurality of contact blocks 209 are fixedly connected to the side of the contact ring 208 away from the adjusting rod 206. The plurality of contact blocks 209 are evenly distributed on the contact ring 208. When the contact ring 208 is used to contact the wall surface, the contact blocks 209 installed on the contact ring 208 can improve the stability of the connection between the contact ring 208 and the wall. The contact blocks 209 can improve the use effect of the contact ring 208. The adjusting rod 206 is a titanium alloy rod. The surface of the rod body of the adjusting rod 206 made of titanium alloy is relatively hard, which also makes it difficult for the surface of the rod body of the adjusting rod 206 to deform after long-term use, and has a long service life.

[0033] In the embodiments of the present invention, please refer to Figure 4 and Figure 5 The auxiliary device 3 includes a connecting rod 31, which is fixedly connected to the rebound tester body 1. One end of the connecting rod 31 away from the rebound tester body 1 is fixedly connected to a limit ring 32. Both ends of the side of the limit ring 32 are provided with a card slot 33. A marker pen 35 slides through the limit ring 32. Both ends of the arc surface of the marker pen 35 are fixedly connected with a card block 34. The two card blocks 34 are slidably connected to the two card slots 33 respectively. When the rebound tester body 1 is used to test the wall, it is found that there are many test points that need to be tested on the wall, which causes the workers to forget the test point positions when testing. At this time, the workers need to measure the same test point position of the wall twice. The secondary test will waste a lot of time and affect the detection process. When the monitoring point position of the wall is detected, the marker pen 35 is pushed upward. The movement of the marker pen 35 will drive the card block 34 to slide out of the card slot 33, and the limit ring 32 passes through the connecting rod 3 1 is connected to the rebound tester body 1, so that the marker pen 35 can be taken out from the limiting ring 32, and the marker pen 35 can be used to mark the test points that have been tested, which can effectively avoid the situation of forgetting the test points. The side walls of both ends of the slot 33 are fixedly connected with elastic pads 37, and the cross-section of the elastic pad 37 is rectangular. When the block 34 contacts the slot 33, the elastic pad 37 installed in the slot 33 can improve the tightness of the connection between the block 34 and the slot 33, thereby improving the stability of the marker pen 35 in the limiting ring 32. The arc surface of the marker pen 35 is fixedly connected with a plurality of auxiliary blocks 36, and the plurality of auxiliary blocks 36 are evenly distributed on the arc surface of the marker pen 35. When the marker pen 35 is used to mark the wall position that has been tested, the auxiliary block 36 installed on the marker pen 35 can increase the friction between the hand and the pen body of the marker pen 35, thereby improving the efficiency of using the marker pen 35.

[0034] The working principle of a concrete rebound tester provided by the utility model is as follows: when the rebound tester body 1 needs to be used to detect the concrete wall surface, the connecting groove 204 on the connecting ring 203 is connected with the connecting block 205 on the fixing ring 201, and the connecting ring 203 can be installed on the fixing ring 201. At this time, the detection head 4 is used to contact the wall, and the contact ring 208 will contact the wall first. The worker only needs to fit the contact ring 208 with the wall to avoid the deviation between the detection head 4 on the rebound tester body 1 and the wall. Press the rebound tester body 1, and the connecting rod 31 slides in the connecting block 205 and moves with the rebound tester body 1, thereby driving the contact ring 208 to move in the direction of the rebound tester body 1. At this time, the spring 207 is in a stretched state, and the wall can be detected by the detection head 4. After the detection, the spring 207 is restored to drive the adjustment rod 206 and the contact ring 208 to move, so that the angle between the detection head 4 and the wall can be adjusted by the support device 2 next time. The support device 2 can prevent the detection head 4 from deviating from the wall when in use, thereby affecting the detection value. When the fixing ring 201 is connected to the connecting ring 203, the fixing block 202 needs to be inserted into the connecting groove 204 before the connection between the fixing ring 201 and the connecting ring 203 is completed. The metal block 211 installed on the fixing ring 201 and the magnetic block 210 installed on the connecting ring 203 can guide the fixing block 202 and the connecting groove 204 to be connected by the magnetic force between the two before the fixing block 202 and the connecting groove 204 are connected. The connection groove 204 is aligned to improve the connection efficiency between the fixed block 202 and the connection groove 204. When the contact ring 208 is used to contact the wall surface, the contact block 209 installed on the contact ring 208 can improve the stability of the connection between the contact ring 208 and the wall. The contact block 209 can improve the use effect of the contact ring 208. The surface of the adjusting rod 206 made of titanium alloy is relatively hard, which also makes it difficult for the surface of the adjusting rod 206 to deform under long-term use, and has a longer service life.

[0035] When the wall is tested using the rebound tester body 1, it is found that there are many test points that need to be tested on the wall, which causes the worker to forget the test point position when testing. At this time, the worker needs to measure the same test point position of the wall twice. The secondary test will waste a lot of time and affect the detection process. When the monitoring point position of the wall is detected, the marker pen 35 is pushed upward. The movement of the marker pen 35 will drive the card block 34 to slide out of the card slot 33. The limit ring 32 is connected to the rebound tester body 1 through the connecting rod 31, so that the marker pen 35 can be removed from the limit ring 32. The marker pen 35 can be taken out and the test points that have been tested can be marked with the marker pen 35, which can effectively avoid the situation of forgetting the test points. When the block 34 contacts the card slot 33, the elastic pad 37 installed in the card slot 33 can improve the tightness of the connection between the block 34 and the card slot 33, thereby improving the stability of the marker pen 35 in the limiting ring 32. When the marker pen 35 is used to mark the wall position that has been tested, the auxiliary block 36 installed on the marker pen 35 can increase the friction between the hand and the pen body of the marker pen 35, thereby improving the efficiency of using the marker pen 35.
