Description

Technical Field

[0001] The utility model relates to the technical field of thickness measurement, in particular to a plaster layer thickness measuring device. Background Art

[0002] Cement mortar is a mortar made of cement, fine aggregate and water in a certain proportion. In construction projects, cement mortar is used as a binder for block masonry materials in wall masonry and for indoor and outdoor plastering. Plastering is divided into advanced, intermediate and general plastering. Advanced plastering is generally 20-25cm thick and needs to be constructed in three times. The plastering layer cannot be too thick, otherwise cracks are prone to occur. Therefore, in advanced plastering operations, its thickness needs to be measured after each plastering in order to understand the construction status in a timely manner.

[0003] Patent CN220794178U discloses a plaster layer thickness measurement system, which transmits ultrasonic waves to the wall, receives ultrasonic reflection echo signals, converts ultrasonic reflection echo signals into electrical signals, and performs multiple signal processing to obtain the plaster layer thickness of the measured wall. Although the thickness value measured by this measurement system is accurate and does not damage the plaster layer, the system has a complex and precise structure, and has high use and maintenance costs, so it is not the first choice for micro-small enterprises and individual construction units. When using traditional tools to measure the thickness of the plaster layer, on different construction planes, due to the variability of the construction area and construction height, the horizontality and stability of the measuring equipment cannot be guaranteed, which affects the measurement accuracy and work efficiency.

[0004] At present, there is an urgent need for a plaster layer thickness measurement tool with simple structure, strong applicability, low cost and guaranteed measurement accuracy to improve the quality control of construction workers and managers on the construction site. Utility Model Content

[0005] Aiming at the technical problems that the existing devices for measuring the thickness of plaster layer have complex structures, high costs, or cannot adapt to various measurement environments and the measurement accuracy needs to be improved, the utility model provides a device for measuring the thickness of plaster layer.

[0006] The technical solution of this utility model is as follows:

[0007] A plaster layer thickness measuring device comprises a sleeve, a measuring rod is arranged along the central axis of the sleeve, one end of the measuring rod is connected to a push handle, and the other end is a tip for inserting into the plaster layer, a connecting rod is arranged on the measuring rod, a scale is fixed on the outer side of the sleeve, a sliding groove parallel to the scale is also arranged on the outer side of the sleeve, the other end of the connecting rod passes through the sliding groove and is connected to a pointer, and the pointer is used to indicate the scale on the scale;

[0008] It also includes legs and a base. There are at least two legs. The upper end of the leg is rotatably assembled on the outer side of one end of the sleeve through which the measuring rod passes. A ball head is arranged at the lower end of the leg. A groove matching the ball head is arranged at the top of the base. The ball head is slidably connected to the groove and can rotate in a universal direction.

[0009] Furthermore, a hinge seat is installed on the outer side of one end of the sleeve through which the measuring rod passes, the number of the hinge seats is consistent with the number of the legs, and the hinge seat is hinged to the legs.

[0010] Furthermore, a level is arranged on the outer side surface of the sleeve.

[0011] Furthermore, a light source is installed on the outer side of the end of the sleeve through which the measuring rod passes.

[0012] Furthermore, a light source is installed on the side of the scale opposite to the slide slot.

[0013] Furthermore, along the direction in which the measuring rod passes through the sleeve, a piston and a spring are sequentially sleeved on the measuring rod inside the sleeve.

[0014] The spring is limited by the inner side surface of the piston and the bottom end of the sleeve. During measurement, the spring and the piston increase the damping during the advancement process, thereby improving the stability of the measuring rod during the measurement process. After the measurement is completed, the elastic force of the spring pushes the measuring rod to automatically return to the inside of the sleeve.

[0015] Furthermore, the outer side of the piston is wrapped with a rubber layer.

[0016] Furthermore, the outside of the scale is covered with a transparent magnifying lens.

[0017] It is convenient for operators to read the data on the scale.

[0018] Furthermore, the minimum graduation value on the scale is 1 mm, 0.5 mm, 0.1 mm, 0.05 mm or 0.02 mm.

[0019] The beneficial effects of the utility model are:

[0020] The utility model provides a plaster layer thickness measuring device with simple structure, easy and accurate reading and strong applicability. When not in use, the measuring rod is stored in the sleeve, which will not accidentally injure the operator. The legs are detachable, which is convenient for storage and carrying. When in use, according to the specific conditions of the plaster layer, the operator can adjust the opening and closing angles of the legs and keep the bottom surface of the base completely in contact with the plaster layer. Compared with using the legs alone, the base can increase the force-bearing area of ​​the plaster layer. When the push handle is pressed with the same force, the pressure on the plaster layer becomes smaller, and the plaster layer thickness measuring device is not easy to sink into the plaster layer in the final setting state, thereby ensuring the stable state of the plaster layer thickness measuring device and improving the accuracy of the reading during measurement.

[0026] Example 1

[0027] Reference Figure 1-Figure 2A plaster layer thickness measuring device comprises a sleeve 4, wherein a measuring rod 2 is provided along the central axis of the sleeve 4, one end of the measuring rod 2 is connected to a push handle 1, and the other end is a tip for inserting into the plaster layer, and along the direction in which the measuring rod 2 passes through the sleeve 4, a connecting rod 5, a piston 3 wrapped with a rubber layer on the outside, and a spring 9 are provided on the measuring rod 2 inside the sleeve 4 in sequence, wherein the piston 3 and the spring 9 are sleeved on the measuring rod 2. A light source 13 is installed on the outside of the end of the sleeve 4 through which the measuring rod 2 passes, and the light source 13 is a non-plug-in LED lamp, a scale 7 is fixed on the outer side of the sleeve 4, and a slide groove parallel to the scale is also provided on the outer side of the sleeve 4, and the other end of the connecting rod 5 passes through the slide groove to connect a pointer 6, and the pointer 6 is used to indicate the scale on the scale 7, and the minimum graduation value on the scale 7 is 0.5 mm, and a light source 2 14 is installed on the side of the scale 7 opposite to the slide groove, and the light source 2 14 is a non-plug-in LED lamp, and the scale The outside of the ruler 7 is covered with a transparent magnifying lens, and a spirit level 10 is arranged on the outer side of the sleeve 4, and the spirit level 10 is a universal level bubble; it also includes legs 8 and a base 12, the number of legs 8 is two, and a hinge seat 11 is also installed on the outer side of one end of the sleeve 4 through which the measuring rod 2 passes, and the number of the hinge seats 11 is consistent with the number of the legs 8. The hinge seat 11 is hinged to the legs 8, and a ball head is arranged at the lower end of the leg 8. A groove adapted to the ball head is opened on the top of the base 12, and the ball head is slidably connected to the groove and can rotate universally.

[0028] Before measuring, assemble the legs 8 with other parts of the plastering layer thickness measuring device. If it is dim in the scene, you can turn on the non-plug-in LED lamp as a light source for the hinged fixation of the legs 8 and reading illumination. According to the position and area of ​​the plastering layer in the final setting state, the opening and closing position of the legs 8 is fixed by the hinge seat 11 and the hinged fixation of the legs 8. The ball head at the lower end of the leg 8 rotates universally in the base 12 to ensure that the bottom surface of the base 12 is completely in contact with the plastering layer. In order to make the two legs 8 at the same opening and closing angle and the reading is accurate, you can make fine adjustments while observing the universal bubble level on the sleeve 4. When the bubble in the universal bubble is at the center of the circle, the plastering layer thickness measuring device is considered to be in a horizontal and stable state.

[0029] When starting to measure, push the pushing handle 1. When the tip of the measuring rod 2 touches the plaster layer, record the reading of the pointer 6 on the scale 7. When the tip is inserted into the bottom of the plaster layer and cannot be pushed further, record the reading again. The difference between the two readings is the thickness of the plaster layer. During the pushing process, the friction between the piston 3 and the inner wall of the sleeve 4 and the resistance of the spring 9 can ensure the stability of the plaster layer thickness measuring device during the measurement process.

[0030] After the measurement is completed, the push handle 1 is released, and the elasticity of the spring 9 causes the measuring rod 2 to return to the inside of the sleeve. For easy storage, the supporting legs 8 can be disassembled.

[0031] Example 2

[0032] The difference from the first embodiment is that the number of the legs 8 is three, and the minimum graduation value on the scale 7 is 0.1 mm.
