Abstract
Description
Technical Field
[0001] This utility model relates to the field of rebound hammer technology, and more specifically to a rebound hammer that can be stably placed on a wall. Background Technology
[0002] The basic principle of a rebound hammer is to use a spring to drive a hammer. The hammer strikes a spring rod that is in perpendicular contact with the concrete surface with constant kinetic energy, causing local concrete deformation and absorbing some energy. The other part of the energy is converted into the rebound kinetic energy of the hammer. When all the rebound kinetic energy is converted into potential energy, the hammer rebounds to its maximum distance. The instrument displays the maximum rebound distance of the hammer as the rebound value (the ratio of the maximum rebound distance to the initial length of the spring).
[0003] Current technology has shortcomings: During the use of the rebound hammer, the impact rod needs to be in close contact with the wall, and the test is carried out by the internal impact hammer striking the impact rod. However, the impact rod has a simple structure and cannot accurately control the angle between the impact rod and the wall, which affects the test results. At the same time, the existing impact rod has a small contact area with the wall, so the friction is small and it is easy to slip during use, which also affects the test results. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a rebound hammer that can be stably placed on a wall to solve the problems existing in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a rebound hammer capable of stable placement on a wall, comprising a rebound hammer mechanism, and further comprising: an adjustment mechanism, a first connecting rod mechanism, an anti-slip mechanism, and a second connecting rod mechanism. The inner side wall of the rebound hammer mechanism is movably connected to the side of the first connecting rod mechanism, and the inner side wall of the rebound hammer mechanism is movably connected to the side of the second connecting rod mechanism. The bottom end of the anti-slip mechanism is movably connected to the top end of the first connecting rod mechanism. The rebound hammer mechanism includes a rebound hammer body, and a striking rod is movably connected to the top end of the rebound hammer body. A placement hole is provided in the fixed striking area of the rebound hammer body. The first connecting rod mechanism includes a connecting rod body, and the side of the connecting rod body is movably connected to the side of the placement hole. The anti-slip mechanism includes an anti-slip seat, and the bottom end of the anti-slip seat is movably connected to the top end of the connecting rod body by a pin. The anti-slip seat has a ring structure, and the central axis of the anti-slip seat is in a straight line with the striking rod. An anti-slip groove is provided at the top end of the anti-slip seat.
[0006] Furthermore, a pressure spring is fixedly connected to the bottom end of the connecting rod body, and the bottom end of the pressure spring is fixedly connected to the bottom end of the placement hole.
[0007] Furthermore, the inner side wall of the rebound spring body is movably connected to the side of the second connecting rod mechanism. The structure of the second connecting rod mechanism is the same as that of the first connecting rod mechanism. The adjustment mechanism includes a threaded column, the side of which is threadedly connected to the inner side wall of the second connecting rod mechanism. A connecting block is movably sleeved on the top of the threaded column, and a slider is movably connected to the top of the connecting block via a pin. A groove is provided at the bottom of the anti-slip seat, and the side of the groove is movably connected to the side of the slider.
[0008] Furthermore, the bottom of the anti-slip base is provided with a scale corresponding to the position of the slide groove, and the side of the slider is provided with a marking line corresponding to the position of the scale.
[0009] Furthermore, the slide groove has a T-shaped structure, and a roller is movably sleeved on the side of the slider, with the bottom end of the roller movably connected to the bottom end of the slide groove.
[0010] Furthermore, a fixing block is fixedly sleeved on the side of the threaded column, and a fixing nut is threadedly connected to the side of the threaded column.
[0011] The technical effects and advantages of this utility model are as follows:
[0012] 1. This utility model increases the contact area with the wall by tightly attaching the top of the anti-slip seat to the wall and ensuring that the entire top of the anti-slip seat is in contact with the wall, thereby increasing the friction between the anti-slip seat and the wall, preventing the impact rod from sliding, and maintaining a suitable angle between the impact rod and the wall, which helps to improve the accuracy of the test results.
[0013] 2. In this utility model, when the top of the anti-slip base is tightly attached to the wall, the top of the pressure block first contacts the wall, causing the pressure block to retract into the mounting hole and contact the pressure switch. The pressure switch controls the indicator light to emit a green light. When a gap appears between the anti-slip base and the wall, the return spring pushes the pressure block upward, separating the pressure block from the pressure switch. The pressure switch then controls the corresponding indicator light to emit a red light, indicating that a gap exists between the anti-slip base and the wall. Therefore, only when all four indicator lights emit green light does it indicate that the entire top of the anti-slip base is in contact with the wall, allowing for detection. Conversely, if the gap is not clear, the device can be adjusted, facilitating device adjustment and improving work efficiency.
[0014] 3. This utility model loosens the fixing nut, drives the threaded column to rotate through the fixing block, and causes the threaded column to move up and down along the inner wall of the second connecting rod mechanism through the thread, so that the slider slides along the slide groove, thereby driving the anti-slip seat to rotate along the top pin of the connecting rod body. The inclination angle between the anti-slip seat and the spring rod is determined by the position of the scale marked by the side marking line of the slider. Then, the fixing nut is tightened to fix the threaded column, which helps to improve the flexibility of the equipment. Attached Figure Description

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The rebound device that can be stably placed on a wall according to this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0022] Reference Figures 1 to 5This utility model provides a rebound hammer that can be stably placed on a wall, including a rebound hammer mechanism 1, and further including: an adjustment mechanism 2, a first connecting rod mechanism 3, an anti-slip mechanism 4, and a second connecting rod mechanism 5. The inner side wall of the rebound hammer mechanism 1 is movably connected to the side of the first connecting rod mechanism 3, and the inner side wall of the rebound hammer mechanism 1 is movably connected to the side of the second connecting rod mechanism 5. The bottom end of the anti-slip mechanism 4 is movably connected to the top end of the first connecting rod mechanism 3. The rebound hammer mechanism 1 includes a rebound hammer body 101, and a striking rod 102 is movably connected to the top end of the rebound hammer body 101. A placement hole 103 is provided in the fixed-point rolling of the rebound hammer body 101. The first connecting rod mechanism 3 includes a connecting rod body 301, and the side of the connecting rod body 301 is movably connected to the side of the placement hole 103. The anti-slip mechanism 4 includes an anti-slip seat 401, and the bottom end of the anti-slip seat 401 is connected to the connecting rod body 301. The top of the anti-slip seat 401 is connected by a pin. The anti-slip seat 401 has a ring structure. The central axis of the anti-slip seat 401 is on the same straight line as the impact rod 102. The top of the anti-slip seat 401 is provided with an anti-slip groove. According to the usage requirements, the adjustment mechanism 2 is adjusted so that the anti-slip seat 401 rotates along the pin at the top of the connecting rod body 301, so that the anti-slip seat 401 and the impact rod 102 maintain a suitable angle, so that the top of the anti-slip seat 401 is pressed tightly against the wall, and the entire top of the anti-slip seat 401 is in contact with the wall, increasing the contact area with the wall, thereby increasing the friction between the anti-slip seat 401 and the wall, preventing the impact rod 102 from sliding, and maintaining a suitable tilt angle between the impact rod 102 and the wall. When in use, push the rebound hammer body 101 to press the impact rod 102 tightly against the wall, start the rebound hammer body 101 so that the impact hammer inside the rebound hammer body 101 hammers the impact rod 102, and tests the wall strength.
[0023] A pressure spring 302 is fixedly connected to the bottom end of the connecting rod body 301. The bottom end of the pressure spring 302 is fixedly connected to the bottom end of the placement hole 103. When the rebound device body 101 is pushed to make the impact rod 102 stick tightly to the wall, the first connecting rod mechanism 3 and the second connecting rod mechanism 5 are both retracted into the rebound device body 101 to ensure that the impact rod 102 is in contact with the wall.
[0024] The inner side wall of the rebounder body 101 is movably connected to the side of the second connecting rod mechanism 5. The structure of the second connecting rod mechanism 5 is the same as that of the first connecting rod mechanism 3. The adjustment mechanism 2 includes a threaded column 201. The side of the threaded column 201 is threadedly connected to the inner side wall of the second connecting rod mechanism 5. A connecting block 205 is movably sleeved on the top of the threaded column 201. A slider 202 is movably connected to the top of the connecting block 205 through a pin. A groove 404 is provided at the bottom of the anti-slip seat 401. The side of the groove 404 is movably connected to the side of the slider 202. Rotating the threaded column 201 causes it to move up and down along the inner wall of the second connecting rod mechanism 5 through the thread, thereby causing the slider 202 to slide along the groove 404. This causes the anti-slip seat 401 to rotate along the top pin of the connecting rod body 301 and maintain a suitable tilt angle with the impact rod 102.
[0025] The bottom of the anti-slip seat 401 is provided with a scale 405 corresponding to the position of the slide groove 404, and the side of the slider 202 is provided with a marking line corresponding to the position of the scale 405. The angle between the spring rod 102 and the wall is determined by pointing to the scale 405 through the marking line.
[0026] The slide groove 404 has a T-shaped structure. The side of the slider 202 is movably fitted with a roller 204. The bottom end of the roller 204 is movably connected to the bottom end of the slide groove 404. When the slider 202 slides along the slide groove 404, the roller 204 rolls along the slide groove 404, reducing the friction between the slider 202 and the slide groove 404.
[0027] The threaded column 201 is fixedly sleeved with a fixing block 203 on its side, which facilitates the rotation of the threaded column 201. The threaded column 201 is threadedly connected to a fixing nut 206 on its side. After the threaded column 201 is adjusted, the fixing nut 206 is tightened so that the bottom end of the fixing nut 206 is tightly attached to the top end of the second connecting rod mechanism 5 to fix the threaded column 201.
[0028] Among them, the first connecting rod mechanisms 3 on both sides are symmetrically distributed along the spring rod 102. The line connecting the center of the adjustment mechanism 2 and the center of the anti-slip seat 401 is perpendicular to the line connecting the center of the first connecting rod mechanisms 3 on both sides, ensuring that after the anti-slip seat 401 rotates along the connecting rod body 301, the spring rod 102 always passes through the center of the anti-slip seat 401.
[0029] The anti-slip base 401 has four mounting holes 406 at its top. A return spring 407 is fixedly connected to the bottom of each mounting hole 406, and a pressure block 402 is fixedly connected to the top of each return spring 407. A buffer spring 409 is fixedly connected to the bottom of each mounting hole 406, and a pressure switch 408 is fixedly connected to the top of each buffer spring 409. An indicator light 403 is fixedly connected to the bottom of the anti-slip base 401 corresponding to the position of the pressure block 402. The four pressure blocks 402 are evenly distributed on the top of the anti-slip base 401. When the top of the anti-slip base 401 is pressed against the wall, the top of each pressure block 402 contacts the wall first, causing the pressure block 402 to engage with the wall. Block 402 is inserted into the mounting hole 406, making the pressure block 402 contact with the pressure switch 408. The pressure switch 408 controls the indicator light 403 to emit a green light. When a gap appears between the anti-slip seat 401 and the wall, the return spring 407 pushes the pressure block 402 upward, causing the pressure block 402 to separate from the pressure switch 408. The pressure switch 408 controls the corresponding indicator light 403 to emit a red light, indicating that there is a gap between the anti-slip seat 401 and the wall. Therefore, only when all four indicator lights 403 emit a green light does it indicate that the entire top of the anti-slip seat 401 is in contact with the wall, which can be detected. Otherwise, the equipment needs to be adjusted.
[0030] The working principle of this utility model is as follows: According to usage requirements, loosening the fixing nut 206 causes the threaded post 201 to rotate via the fixing block 203. The threaded post 201 moves up and down along the inner wall of the second connecting rod mechanism 5 via the thread, causing the slider 202 to slide along the slide groove 404. This causes the anti-slip seat 401 to rotate along the top pin of the connecting rod body 301. The tilt angle between the anti-slip seat 401 and the spring rod 102 is determined by the position of the marking line on the side of the slider 202 pointing to the scale 405. Then, tightening the fixing nut 206 fixes the threaded post 201, pressing the top of the anti-slip seat 401 tightly against the wall. When a gap appears between the anti-slip seat 401 and the wall, the return spring 407 pushes the pressure block 402 upwards, separating the pressure block 402 from the pressure switch 408. The pressure switch 408 then controls... The corresponding indicator light 403 emits a red light, indicating that there is a gap between the anti-slip seat 401 and the wall. Adjust the equipment until all four pressure blocks 402 are in contact with the wall. Then, the pressure blocks 402 are retracted into the mounting holes 406, making the pressure blocks 402 contact the pressure switch 408. The pressure switch 408 controls the indicator light 403 to emit a green light. Therefore, only when all four indicator lights 403 emit a green light does it indicate that the entire top of the anti-slip seat 401 is in contact with the wall, and testing can be performed. Push the rebound hammer body 101 towards the wall. At this time, the connecting rod body 301 and the second connecting rod mechanism 5 are retracted into the placement hole 103, so that the impact rod 102 is tightly attached to the wall. Start the rebound hammer body 101 so that the impact hammer inside the rebound hammer body 101 hammers the impact rod 102 and tests the wall strength.
[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.
