Abstract
Description
Technical Field
[0001] This utility model relates to the field of building component connection testing, and in particular to a testing device for prefabricated building component connections. Background Technology
[0002] The prefabricated building component connection testing device is a device used to test the connection parts of components in prefabricated buildings. It can measure relevant parameters such as connection gaps and evaluate connection quality to ensure the safety and reliability of prefabricated buildings.
[0003] Existing technologies, such as CN208476119U, describe a device for detecting the connection accuracy of prefabricated building components. This device includes a ruler body with tempered glass embedded in its top. Two vernier sliding grooves are symmetrically formed on the outer wall of the ruler body, and a vernier body is movably connected to each groove. Two sliding pins are symmetrically arranged on both sides of the bottom of the vernier body, and these pins are located inside the sliding grooves. This device improves the accuracy of the detection. By installing a lead screw and nut and a fastening lead screw on the vernier body, it facilitates the fixation between the vernier body and the ruler body, making it easier to save and fix data during measurement. In low-light conditions, the use of a switch, an LED bulb, and a battery pack allows for convenient illumination of the tempered glass via the LED bulb, facilitating the transmission of measurement data and improving practicality.
[0004] To address the issue of insufficient equipment length when testing connection accuracy, conventional equipment may be too short when dealing with gaps that are too long, leading to inaccurate measurements and significant deviations in the test results. This results in a failure to accurately reflect the actual situation of the connection gaps in prefabricated building components, increasing subsequent repair costs and safety hazards. Therefore, improvements are needed. Utility Model Content
[0005] The purpose of this invention is to solve the problem of insufficient equipment length when testing connection accuracy in the prior art, and to propose a testing device for the connection of prefabricated building components.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a prefabricated building component connection detection device, comprising a ruler body, a connecting block, a vernier body, a marking block, and a scale plate. The connecting block is fixedly connected to the surface of the ruler body, the vernier body is slidably connected to the inner wall of the ruler body, the marking block is fixedly connected to the surface of the vernier body, and the scale plate is fixedly connected to the surface of the ruler body. An adjustment device is provided on the surface of the connecting block. The adjustment device includes a sliding groove and a square frame. The sliding groove is formed on the inner wall of the connecting block, and the square frame is slidably connected to the surface of the sliding groove. A connecting plate is fixedly connected to one end of the square frame.
[0007] Furthermore, linkage blocks are fixedly connected to both sides of the connecting plate, and sliding rods are fixedly connected to the surface of the linkage blocks.
[0008] Furthermore, a stop block is fixedly connected to the end of the slide rod away from the linkage block, a limit block is fixedly connected to the surface of the connecting block, and the slide rod is slidably connected to the inner wall of the limit block.
[0009] Furthermore, a return spring is sleeved and connected to the surface of the slide rod. One end of the return spring is fixedly connected to the surface of the stop block, and the end of the return spring away from the stop block is fixedly connected to the surface of the limiting block.
[0010] Furthermore, the surface of the vernier body is provided with a limiting device, which includes a roll of cloth and a protrusion. The roll of cloth is disposed above the body of the ruler. The protrusion is fixedly connected to the upper surface of the vernier body. The protrusion is fixedly connected to one end of the roll of cloth. A fixing block is fixedly connected to the upper surface of the connecting block. A roller is rotatably connected to the surface of the fixing block. The roll of cloth is wound around the surface of the roller.
[0011] Furthermore, a connecting rod is fixedly connected to one end of the reel, a tension spring is fixedly connected to the inner wall of the fixing block, and a fixing strip is fixedly connected to the end of the tension spring away from the fixing block.
[0012] Furthermore, a fixing plate is fixedly connected to one end of the fixing strip, and a positioning block is fixedly connected to the surface of the fixing plate. The positioning block is inserted into the inner wall of one end of the roll.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0014] 1. In this utility model, by setting an adjustment device, when the user pulls the connecting plate during use, the connecting plate drives the square frame to slide out of the slide groove. At the same time, the slide rod slides under the restriction of the limiting block, and the return spring is compressed and deformed in turn. At this time, the connecting block is in an extended state. By setting an adjustment device, the length of the connecting block is effectively extended, which plays a role in flexibly adapting to gaps of different lengths. When general equipment is used for testing, when faced with gaps that are too long, the equipment may be too short, resulting in inaccurate measurements and large deviations in the test results. This makes it impossible to truly reflect the actual situation of the connection gaps of prefabricated building components, increasing subsequent repair costs and safety hazards. This adjustment device effectively avoids the quality risks caused by testing errors and improves the reliability of equipment testing.
[0015] 2. In this utility model, by setting a limiting device, when the user pulls the fixed plate during use, the fixed plate causes the tension spring to deform under force, and the positioning block disengages from the inner wall of the roll. At this time, the user inserts the vernier body into the gap, and the vernier body slides, simultaneously moving the fixed block. Then, the user holds the connecting rod and rotates it according to the fabric roll, and the connecting rod drives the roll to rotate, and the roll retracts the fabric. By setting a limiting device, the position of the vernier body is effectively fixed, which prevents the vernier body from sliding during the detection process and affecting the detection accuracy. In general detection equipment, the existing fixed vernier usually uses a nut and screw to abut against the scale plate. After long-term use, the scale plate will wear, which may cause the scale plate to become blurred and the scale to be difficult to see. This limiting device can quickly and accurately fix the vernier body, improving the convenience of the equipment. Attached Figure Description

[0023] Please see Figures 1-5This utility model provides a technical solution: a prefabricated building component connection detection device, including a ruler body 1, a connecting block 2, a vernier body 3, a marking block 4 and a scale plate 5. The connecting block 2 is fixedly connected to the surface of the ruler body 1, the vernier body 3 is slidably connected to the inner wall of the ruler body 1, the marking block 4 is fixedly connected to the surface of the vernier body 3, the scale plate 5 is fixedly connected to the surface of the ruler body 1, and an adjustment device 6 is provided on the surface of the connecting block 2.
[0024] The specific settings and functions of the adjustment device 6 and the limit device 7 will be explained in detail below.
[0025] In this embodiment: the adjusting device 6 includes a slide 61 and a square frame 62. The slide 61 is formed on the inner wall of the connecting block 2. The square frame 62 is slidably connected to the surface of the slide 61. A connecting plate 63 is fixedly connected to one end of the square frame 62.
[0026] The effect achieved by the above components is that by setting the square frame 62, it is easier to extend the length of the connecting block 2, thereby making it easier for users to detect gaps.
[0027] Specifically, linkage blocks 64 are fixedly connected to both sides of the connecting plate 63, and sliding rods 65 are fixedly connected to the surface of the linkage blocks 64.
[0028] The effect achieved by the above components is that by setting the connecting block 2, the connecting plate 63 can be moved while the sliding rod 65 is moved.
[0029] Specifically, a stop block 66 is fixedly connected to the end of the slide rod 65 away from the linkage block 64, and a limit block 67 is fixedly connected to the surface of the connecting block 2. The slide rod 65 is slidably connected to the inner wall of the limit block 67.
[0030] The effect achieved by the above components is that by setting the limiting block 67, it is convenient to limit the sliding of the slide rod 65.
[0031] Specifically, a return spring 68 is sleeved and connected to the surface of the slide rod 65. One end of the return spring 68 is fixedly connected to the surface of the stop block 66, and the end of the return spring 68 away from the stop block 66 is fixedly connected to the surface of the limit block 67.
[0032] The effect achieved by the above components is that by setting the return spring 68, the function of automatic reset of the square frame 62 can be easily realized.
[0033] Specifically, the surface of the vernier body 3 is provided with a limiting device 7, which includes a roll of cloth 71 and a protrusion 72. The roll of cloth 71 is located above the body 1. The protrusion 72 is fixedly connected to the upper surface of the vernier body 3 and to one end of the roll of cloth 71. A fixing block 73 is fixedly connected to the upper surface of the connecting block 2. A roller 74 is rotatably connected to the surface of the fixing block 73. The roll of cloth 71 is wound around the surface of the roller 74.
[0034] The effect achieved by the above components is that, by setting the cooperation between the roll cloth 71 and the roll shaft 74, the stretching and winding of the roll cloth 71 can be used to intuitively reflect the moving distance of the vernier body 3 when the vernier body 3 slides, while accurately limiting the sliding range of the vernier body 3.
[0035] Specifically, a connecting rod 75 is fixedly connected to one end of the scroll 74, a tension spring 76 is fixedly connected to the inner wall of the fixing block 73, and a fixing strip 77 is fixedly connected to the end of the tension spring 76 away from the fixing block 73.
[0036] The effect achieved by the above components is that by setting the connecting rod 75, it is convenient for the user to rotate the shaft.
[0037] Specifically, a fixing plate 78 is fixedly connected to one end of the fixing strip 77, and a positioning block 79 is fixedly connected to the surface of the fixing plate 78. The positioning block 79 is inserted into the inner wall of one end of the scroll 74.
[0038] The effect achieved by the above components is that by setting the positioning block 79, it is easy to fix the roller 74, thereby keeping the cloth 71 taut and stably limiting the position of the vernier body 3.
[0039] Working principle: When using the equipment, the user pulls the connecting plate 63, which then drives the square frame 62 to slide out of the slide groove 61. At the same time, the slide rod 65 slides under the restriction of the limiting block 67, and the return spring 68 is compressed and deformed in turn. At this time, the connecting block 2 is in an extended state. By setting the adjustment device 6, the length of the connecting block 2 is effectively extended, which plays a flexible role in adapting to gaps of different lengths. When general equipment is used for testing, when the gap is too long, the equipment may be too short, resulting in inaccurate measurement and a large deviation in the test results. This makes it impossible to truly reflect the actual situation of the connection gaps of prefabricated building components, increasing subsequent repair costs and safety hazards. The adjustment device 6 effectively avoids the quality risks caused by testing errors and improves the reliability of equipment testing.
[0040] When using the equipment, the user pulls the fixing plate 78, which in turn causes the tension spring 76 to deform under force. The positioning block 79 then detaches from the inner wall of the scroll 74. At this point, the user inserts the ruler body 1 into the gap, causing the vernier body 3 to slide, simultaneously moving the fixing block 73. The user then grips and rotates the connecting rod 75 according to the condition of the rolled cloth 71. The connecting rod 75 then rotates the scroll 74, which in turn retracts the rolled cloth 71. By setting the limiting device 7, the position of the vernier body 3 is effectively fixed, preventing slippage during the measurement process and ensuring accuracy. In general testing equipment, existing fixed verniers typically use a nut and screw to abut against the scale plate 5. Over time, this can cause wear on the scale plate 5, potentially leading to blurred or illegible graduations. This limiting device 7 can quickly and accurately fix the vernier body 3, improving the equipment's convenience.
