Description

Technical Field

[0001] This utility model relates to the field of building installation technology, specifically a high-precision level calibration device for building installation. Background Technology

[0002] Building installation refers to the process of assembling, fitting, and fixing various equipment, components, and facilities into or on a building according to design requirements during construction. It encompasses multiple aspects, including but not limited to electrical installation, water supply and drainage system installation, heating, ventilation, and air conditioning (HVAC) system installation, fire protection system installation, and intelligent system installation. Cable tray installation is one of the steps in electrical installation, and horizontal alignment is required during cable tray installation.

[0003] The existing leveling method involves installers using a bubble level. However, since the bubble in the bubble level is small and the distance between two cable trays is relatively far, when one person is installing the cable trays, the installer needs to repeatedly adjust the level of the cable trays and check the bubble level, which is inefficient. Therefore, a high-precision leveling device for building installation is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a high-precision level calibration device for building installation, which has the advantages of efficient calibration. It solves the problem that the bubble level of the bubble level is too small, and the distance between two cable trays is too far. When one person is setting it up, the installer needs to repeatedly adjust the level of the cable trays and check the level of the bubble, resulting in low calibration efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-precision level calibration device for building installation, comprising a sleeve, telescopic rods slidably mounted on both the left and right ends of the sleeve, placement blocks fixedly mounted on opposite sides of the two telescopic rods, a sector-shaped disk fixedly mounted at the bottom front end of the sleeve, an angle gauge provided on the front edge of the sector-shaped disk, a pointer rotatably mounted at the center of the front of the sleeve, three first guide blocks provided on the sector-shaped disk, first indicator lights fixedly mounted on both the left and right ends of the top of the sleeve, a second indicator light fixedly mounted at the center of the top of the sleeve, a positioning mechanism provided on the sleeve, and a battery fixedly mounted on the back of the sleeve.

[0006] Furthermore, the positioning mechanism includes snap-fit ​​holes, pressing plates, locking blocks, racks, and telescopic springs. Snap-fit ​​holes are provided at both ends of the front side of the sleeve. Racks are fixedly installed on the front sides of both telescopic rods. Two pressing plates are rotatably installed on the front side of the sleeve, on the side opposite to the two snap-fit ​​holes. Locking blocks are fixedly installed at the end of the pressing plates near the snap-fit ​​holes. The locking blocks pass through the snap-fit ​​holes and extend into the racks. The racks match the locking blocks. Telescopic springs are fixedly installed on the front side of the sleeve, above and below the pressing plates. The end of the telescopic springs away from the sleeve is fixedly connected to the pressing plates.

[0007] Furthermore, a second guide block is provided at the bottom of the back of the pointer. All three first guide blocks are fan-shaped guide blocks. The area of ​​the middle first guide block is smaller than that of the left and right first guide blocks. The first guide block and the second guide block are matched. The left first guide block is electrically connected to the left first indicator light. The right first guide block is electrically connected to the right first indicator light. The second indicator light is electrically connected to the middle first guide block.

[0008] Furthermore, the bottom of the placement block is provided with resistance-increasing grooves.

[0009] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0010] 1. This high-precision level calibration device for building installation, through the setting of guide blocks and indicator lights, allows the installation personnel to grasp the level status by observing the illumination of the indicator lights during level calibration, which facilitates the installation personnel in level calibration and achieves the purpose of efficient calibration. It solves the problem that the bubble of the bubble level is small and the distance between two cable trays is far, so when one person is installing, the installation personnel need to repeatedly adjust the level of the cable trays and check the level of the bubble, resulting in low calibration efficiency.

[0011] 2. This high-precision level calibration device for building installation can adjust the spacing of the placement blocks according to different cable tray spacings through the positioning mechanism, which improves the practicality of the device. Attached Figure Description

[0017] 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.

[0018] Please see Figure 1-4 This embodiment of a high-precision level calibration device for building installation includes a sleeve 1. Telescopic rods 2 are slidably installed on both the left and right ends inside the sleeve 1. Placement blocks 3 are fixedly installed on the opposite sides of the two telescopic rods 2. A fan-shaped disk 4 is fixedly installed at the bottom front end of the sleeve 1. An angle ruler 5 is provided on the front edge of the fan-shaped disk 4. A pointer 6 is rotatably installed at the front center of the sleeve 1. Three first guide blocks 7 are provided on the fan-shaped disk 4. First indicator lights 8 are fixedly installed on both the left and right ends of the top of the sleeve 1. A second indicator light 9 is fixedly installed at the top center of the sleeve 1. A positioning mechanism 10 is provided on the sleeve 1. A storage battery 11 is fixedly installed on the back of the sleeve 1.

[0019] A second guide block 61 is provided at the bottom of the back of the pointer 6. All three first guide blocks 7 are fan-shaped guide blocks. The area of ​​the middle first guide block 7 is smaller than that of the left and right first guide blocks 7. The first guide block 7 matches the second guide block 61. The left first guide block 7 is electrically connected to the left first indicator light 8. The right first guide block 7 is electrically connected to the right first indicator light 8. The second indicator light 9 is electrically connected to the middle first guide block 7.

[0020] It should be noted that the second conductor block 61, the first conductor block 7, the first indicator light 8, and the second indicator light 9 are all electrically connected to the battery 11. The first indicator light 8 is red, and the second indicator light 9 is green.

[0021] Specifically, when calibrating the cable tray level, first place the two placement blocks 3 at the center of the two cable trays. The pointer 6 swings on the sector disk 4 according to the level of the two cable trays. When the right cable tray is higher, the pointer 6 swings in the left half of the sector disk 4. At this time, the second guide block 61 contacts the first guide block 7 on the left and connects the circuit of the first indicator light 8 on the left, and the first indicator light 8 on the left lights up. Similarly, when the left cable tray is higher, the first indicator light 8 on the right will light up. When the two cable trays are level, the second indicator light 9 in the middle will light up. In this way, when the installation personnel perform level calibration, they can grasp the level by observing the lighting of the first indicator light 8 and the second indicator light 9, which facilitates the installation personnel in performing level calibration and achieves the purpose of efficient calibration.

[0022] In addition, by using the angle ruler 5 and pointer 6, the erection personnel can view the current horizontal offset angle and perform high-precision horizontal calibration.

[0023] In this embodiment, the positioning mechanism 10 includes a snap-fit ​​hole 101, a pressing plate 102, a locking block 103, a rack 104, and a telescopic spring 105. Snap-fit ​​holes 101 are provided at both the left and right ends of the front of the sleeve 1. A rack 104 is fixedly installed on the front of each of the two telescopic rods 2. Two pressing plates 102 are rotatably installed on the front of the sleeve 1, located on the opposite side of the two snap-fit ​​holes 101. A locking block 103 is fixedly installed at one end of the pressing plate 102 near the snap-fit ​​hole 101. The locking block 103 passes through the snap-fit ​​hole 101 and extends into the rack 104. The rack 104 matches the locking block 103. A telescopic spring 105 is fixedly installed on the front of the sleeve 1, above and below the pressing plate 102. The end of the telescopic spring 105 away from the sleeve 1 is fixedly connected to the pressing plate 102.

[0024] Specifically, pressing the pressing plates 102 on both sides stretches the telescopic spring 105. The pressing plates 102, along with the locking blocks 103, disengage from the rack 104. The telescopic rods 2 on both sides slide, adjusting the placement blocks 3 to the target spacing. Releasing the pressing plates 102 allows the telescopic springs 105 to reset and engage with the locking blocks 103 in the rack 104, fixing the telescopic rods 2 and the placement blocks 3. In this way, the spacing of the placement blocks 3 can be adjusted according to different cable tray spacings.

[0025] In this embodiment, the bottom of the placement block 3 is provided with resistance-increasing grooves.

[0026] Specifically, the friction coefficient between the placement block 3 and the placement surface can be increased by setting the friction-enhancing texture, thereby improving the stability of the device placement.
