Description
Technical Field
[0001] This utility model relates to the field of rapid detection technology for the thickness of external wall insulation materials, specifically a rapid detection caliper for the thickness of external wall insulation materials. Background Technology
[0002] External wall insulation materials are functional materials used on building exterior walls, primarily to block heat transfer between indoor and outdoor spaces, reducing energy consumption and improving building energy efficiency. These materials maintain stable indoor temperatures by reducing heat conduction, convection, and radiation, thus lowering energy requirements for heating or cooling. A rapid thickness measurement caliper for external wall insulation materials is a professional measuring tool used for quickly and accurately measuring the thickness of such materials.
[0003] However, existing calipers for rapid thickness measurement of external wall insulation materials have the following drawbacks:
[0004] (1) The existing calipers for rapid detection of the thickness of external wall insulation materials have a weak function of accurate measurement. Most of the existing devices use the method of directly pulling the caliper to determine the position and then positioning the device. This may result in the continuous adjustment of the length of the caliper, causing the device to be inaccurate.
[0005] (2) The existing calipers for rapid thickness detection of external wall insulation materials have weak stability. The existing device needs to be placed against the surface of the insulation material and the calipers need to be inserted into it for measurement. Due to the hardness of the insulation material, the calipers may shake and tilt when inserted, resulting in poor measurement effect of the device. Utility Model Content
[0006] The purpose of this invention is to provide a caliper for rapid detection of the thickness of external wall insulation materials, so as to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a caliper for rapid detection of the thickness of external wall thermal insulation materials, comprising a precision adjustment component and a stabilization component. The precision adjustment component consists of a fixed frame, an adjustment shaft, a drive gear, a driven gear, a friction rod, a measuring scale, and a friction groove. The bottom of the fixed frame is rotatably connected to the adjustment shaft, the top of the adjustment shaft is fixedly connected to the drive gear, the outer surface of the drive gear meshes with the driven gear, the top of the driven gear is fixedly connected to the friction rod, the top of the fixed frame has a sliding groove, the inner wall of the sliding groove is slidably connected to the measuring scale, and the side of the measuring scale has a friction groove.
[0008] The stabilizing component consists of a support frame fixed to both sides of one end of the fixing frame and a reinforcing frame. The outer surface of the support frame is provided with an installation component, and the outer surface of the installation component is provided with a reinforcing frame.
[0009] Preferably, the measuring ruler has a scale line A on one side of its top, and the fixing frame has a scale line B on one side of its top. After the operator determines the position of the measuring ruler, they compare the scale line A and the scale line B on the fixing frame to make a reading.
[0010] Preferably, a stabilizing rod is fixedly connected to the bottom of the driven gear, and the bottom of the stabilizing rod is rotatably connected to one side of the inner bottom wall of the fixed frame. The stabilizing rod at the bottom of the driven gear is used to stabilize the rotation of the driven gear.
[0011] Preferably, a rectangular groove is provided at one end edge of the reinforcing frame, and an anti-slip pad is fixedly connected to the inner wall of the rectangular groove. Installing the anti-slip pad on the reinforcing frame can improve the stability of the device when it is supported.
[0012] Preferably, the fixed frame has movable grooves at the center of both ends, and the inner wall of the movable groove is slidably connected to both ends of the outer surface of the measuring ruler, so that the measuring ruler can move horizontally by passing through the movable grooves at both ends of the fixed frame.
[0013] Preferably, the measuring ruler has a fixing groove on its side edge, and a limit block is fixedly connected to the inner wall of the fixing groove. The limit block on the measuring ruler can prevent the measuring ruler from detaching from the fixing frame.
[0014] Compared with this device, the beneficial effects of this utility model are:
[0015] 1. This rapid thickness measurement caliper for external wall insulation materials, through the setup of a fixed frame, adjusting shaft, driving gear, driven gear, friction rod, measuring scale, and friction groove, allows the operator to insert the measuring scale into the insulation material. Rotating the adjusting shaft at the bottom of the fixed frame drives the driving gear, which in turn drives the driven gear, which in turn drives the friction rod at the top. This friction between the friction rod and the friction groove on the side of the measuring scale causes the measuring scale to move horizontally along the interior of the insulation material. This design allows for precise adjustment by the operator, improving the accuracy of the measurements.
[0016] 2. This rapid thickness measurement caliper for exterior wall insulation materials uses a fixed frame, support frame, reinforcement frame, and installation components. During use, the fixed frame has support frames on both sides. Workers need to press the support frames against the wall to ensure stability before inserting the measuring structure into the insulation material. Simultaneously, the installation components allow the reinforcement frame to be installed on the support frames, forming a stable frame. This design prevents the measuring structure from tilting during insertion due to the rigidity of the insulation material. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1-3As shown, this utility model provides a technical solution: a caliper for rapid detection of the thickness of external wall thermal insulation materials, including a precision adjustment component 1 and a stabilizing component 2. The precision adjustment component 1 consists of a fixed frame 101, an adjustment shaft 102, a driving gear 103, a driven gear 104, a friction rod 105, a measuring scale 106, and a friction groove 107. The bottom of the fixed frame 101 is rotatably connected to the adjustment shaft 102, and the top of the adjustment shaft 102 is fixedly connected to the driving gear 103. The outer surface of the driving gear 103 meshes with the driven gear 104, and the top of the driven gear 104 is fixedly connected to the friction rod 105. A sliding groove is provided on the top of the fixed frame 101, and a measuring scale 106 is slidably connected to the inner wall of the sliding groove. A friction groove 107 is provided on the side of the measuring scale 106. The caliper is adjusted by the fixed frame 101 and the adjustment shaft 102. The arrangement of the drive gear 102, driven gear 103, friction rod 105, measuring scale 106, and friction groove 107 allows the operator to insert the measuring scale 106 into the thermal insulation material during use. Rotating the adjusting shaft 102 at the bottom of the fixing frame 101 causes the driving gear 103 to rotate, which in turn drives the driven gear 104. The driven gear 104 then drives the friction rod 105 at the top, allowing friction transmission between the friction rod 105 and the friction groove 107 on the side of the measuring scale 106. This friction drives the measuring scale 106 to move horizontally along the interior of the thermal insulation material. This arrangement facilitates precise adjustment of the device by the operator, improving the accuracy of the measurements.
[0025] The stabilizing component 2 consists of a support frame 201 fixed to both sides of one end of the fixed frame 101 and a reinforcing frame 202. The outer surface of the support frame 201 is provided with an installation component 3, and the outer surface of the installation component 3 is provided with a reinforcing frame 202. With the fixed frame 101, support frame 201, reinforcing frame 202 and installation component 3, in use, the support frame 201 is fixed to both sides of the fixed frame 101. The operator needs to press the support frame 201 against the wall to stabilize the measuring structure when it is inserted into the thermal insulation material. At the same time, the reinforcing frame 202 can be installed on the support frame 201 through the installation component 3, so that the reinforcing frame 202 and the support frame 201 form a stable frame. This setting can prevent the measuring structure from tilting when it is inserted due to the thermal insulation material being too hard.
[0026] The measuring ruler 106 has a scale line A4 on one side of its top, and the fixing frame 101 has a scale line B5 on one side of its top. With the setting of the measuring ruler 106, scale line A4, fixing frame 101 and scale line B5, when in use, the staff determines the position of the measuring ruler 106 and compares the scale line A4 and the scale line B5 on the fixing frame 101 to make a reading.
[0027] A stabilizing rod 6 is fixedly connected to the bottom of the driven gear 104. The bottom of the stabilizing rod 6 is rotatably connected to one side of the inner bottom wall of the fixed frame 101. Through the arrangement of the driven gear 104, the stabilizing rod 6 and the fixed frame 101, the stabilizing rod 6 at the bottom of the driven gear 104 is used to stabilize the rotation of the driven gear 104 during use.
[0028] A rectangular groove is provided on one edge of the reinforcing frame 202, and an anti-slip pad 7 is fixedly connected to the inner wall of the rectangular groove. By setting the reinforcing frame 202 and the anti-slip pad 7, the stability of the device can be improved when the anti-slip pad 7 is installed on the reinforcing frame 202.
[0029] The fixed frame 101 has movable grooves at the center of both ends. The inner wall of the movable groove is slidably connected to the two ends of the outer surface of the measuring ruler 106. With the setting of the fixed frame 101 and the measuring ruler 106, the measuring ruler 106 will move horizontally through the movable grooves at both ends of the fixed frame 101 during use.
[0030] The measuring ruler 106 has a fixing groove on its side edge, and a limiting block 8 is fixedly connected to the inner wall of the fixing groove. With the setting of the measuring ruler 106 and the limiting block 8, the limiting block 8 on the measuring ruler 106 can prevent the measuring ruler 106 from detaching from the fixing frame 101 during use.
[0031] In this invention, the working steps of the device are as follows:
[0032] First step: The fixed frame 101 has support frames 201 fixed on both sides. The staff needs to press the support frames 201 against the wall to make the support frames 201 stable. The measuring structure is inserted into the thermal insulation material. At the same time, the reinforcing frame 202 can be installed on the support frame 201 through the installation component 3, so that the reinforcing frame 202 and the support frame 201 form a stable frame.
[0033] The second step: The staff inserts the measuring ruler 106 into the thermal insulation material, rotates the adjusting shaft 102 at the bottom of the fixing frame 101, so that the adjusting shaft 102 drives the driving gear 103 to rotate, so that the driving gear 103 drives the driven gear 104 to rotate, so that the driven gear 104 drives the friction rod 105 at the top to rotate, so that the friction rod 105 and the friction groove 107 on the side of the measuring ruler 106 perform friction transmission, so that the friction rod 105 drives the measuring ruler 106 to move horizontally, so that the measuring ruler 106 moves along the inside of the thermal insulation material.
