Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically a sampling device for building quality testing. Background Technology

[0002] Construction engineering refers to the physical engineering project formed by the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. Among them, "buildings" refer to projects with roofs, beams, columns, walls, foundations, and the ability to form internal spaces to meet people's needs for production, living, learning, and public activities.

[0003] A search revealed Chinese patent application number 202221827131.3, which discloses a sampling device for building quality testing. The device includes a front end of a housing, a rear end of a housing, a limiter, a drill housing, a drill bit, a pedal, and a threaded post. The inner wall of one end of the rear end of the housing is threaded. The drill bit is aligned with the desired sampling location, and then the pedal is pressed firmly to secure it. Existing sampling devices for building quality testing often have a simple structure, requiring workers to carry a large amount of auxiliary equipment. Sampling is time-consuming and laborious, inconvenient to operate, and inefficient. Furthermore, sampling generates a large amount of debris, significantly impacting the work site. Therefore, this new sampling device for building quality testing addresses the shortcomings of simple structures, the need for workers to carry a large amount of auxiliary equipment, the time-consuming and laborious nature of sampling, the inconvenience of operation, the low sampling efficiency, and the large amount of debris generated during sampling, which significantly impacts the work site.

[0004] Although the aforementioned patents address the problems mentioned in the background technology, such as the relatively simple structure, the need for workers to carry a large amount of auxiliary equipment, the time-consuming and laborious sampling, the inconvenience of operation and sampling, the low sampling efficiency, and the generation of a large amount of debris during sampling, which greatly affects the work site, in actual use, it is not convenient to carry out dust prevention treatment during sampling. Dust is easily generated during sampling, which affects the construction environment. At the same time, it is not convenient to cool down the drill bit during drilling and sampling, which leads to rapid wear of the drill bit and affects the service life of the device.

[0005] Therefore, it is necessary to modify it to effectively prevent dust generation during sampling, implement dustproof treatment, and cool the drill bit during drilling sampling to reduce drill bit wear and improve the service life of the device. Utility Model Content

It solves the problems of inconvenience in dustproofing during sampling, the easy generation of dust during sampling which affects the construction environment, and the difficulty in cooling the drill bit during drilling sampling, leading to rapid drill bit wear and reduced device lifespan.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sampling device for building quality inspection, comprising a chassis, a main rod fixedly connected to the left side of the chassis, handles fixedly connected to both the front and rear sides of the left end of the main rod, a dust cover slidably connected to the right side of the chassis surface, stabilizing mechanisms fixedly connected to the upper and lower sides of the left side of the dust cover, the left end of the stabilizing mechanism fixedly connected to the surface of the chassis, a drive motor slidably connected to the left side inside the chassis, a protective net fixedly connected to the right side of the chassis, the output end of the drive motor extending through the right side of the protective net and fixedly connected to a sampling drill bit located inside the dust cover, a plurality of fan blades located inside the chassis fixedly connected to the left side of the output end of the drive motor, a Velcro female attachment fixedly connected to the right side of the inner surface of the dust cover, an absorbent cotton sleeve provided on the right side inside the dust cover, a Velcro male attachment fixedly connected to the outer surface of the absorbent cotton sleeve, and the outer surface of the absorbent cotton sleeve being movably connected to the inner wall of the dust cover through the Velcro male and female attachments.

[0008] In a preferred embodiment of this invention, the stabilizing mechanism includes a support rod fixedly connected to the top and bottom of the chassis. The end of the support rod away from the chassis has a through-hole, and a stabilizing rod is slidably connected inside the hole. The right end of the stabilizing rod is fixedly connected to the left side of the dust cover, and a limiting piece is fixedly connected to the left end of the stabilizing rod. A first compression spring is sleeved on the surface of the stabilizing rod. The right end of the first compression spring is fixedly connected to the left side of the dust cover, and the left end of the first compression spring is fixedly connected to the right side of the support rod.

[0009] As a preferred embodiment of this utility model, a hinge seat is slidably connected to the right side of the bottom of the main body rod, and an electric telescopic rod is movably connected inside the hinge seat by bolts, with a rubber pad fixedly connected to the bottom end of the electric telescopic rod.

[0010] In a preferred embodiment of this invention, a stabilizing ring is fixedly connected to the surface of the drive motor, the outer surface of the stabilizing ring is slidably connected to the inner wall of the chassis, a buffer pad is fixedly connected to the left side of the drive motor, a second compression spring is fixedly connected to the left side of the buffer pad, and the left end of the second compression spring is fixedly connected to the left side of the inner wall of the chassis.

[0011] As a preferred embodiment of this utility model, a bearing is fixedly connected to the left side of the output end surface of the drive motor, and support plates are fixedly connected to all four sides of the right side of the inside of the housing. A sliding sleeve is fixedly connected to the inner side of the support plate, and the surface of the bearing is slidably connected to the inner wall of the sliding sleeve.

[0012] As a preferred embodiment of this utility model, T-shaped blocks are fixedly connected to the top and bottom of the left side of the dust cover inner wall, and T-shaped grooves that cooperate with the T-shaped blocks are opened on the top and bottom of the chassis, and the surface of the T-shaped blocks is slidably connected to the inner wall of the T-shaped grooves.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model involves removing the absorbent cotton sleeve from inside the dust cover, immersing it in water to fully absorb moisture, and then attaching it to the inside of the dust cover using Velcro straps. The length of the electric telescopic rod can be adjusted according to the height of the marked point, ensuring the rubber pad contacts the ground. The dust cover and sampling drill bit are then aligned with the marked point. The user holds the handle and pushes the device to the right, bringing the dust cover into contact with the building surface. Continuing to push the device brings the sampling drill bit into contact with the building, and then starting the drive motor to rotate the sampling drill bit for drilling and sampling. The fan blades rotate inside the casing, generating airflow within the dust cover to lift dust produced during drilling. Simultaneously, a protective mesh prevents cement debris from entering the casing and affecting the drive motor. Because the absorbent cotton sleeve fully absorbs moisture, dust is adsorbed onto its surface upon contact. Furthermore, after absorbing moisture, the cotton sleeve drips water onto the sampling drill bit as it rotates, reducing drill bit wear. This effectively prevents dust generation during sampling, providing dust protection. Additionally, the drill bit is cooled during drilling, reducing wear and extending the device's lifespan.

[0015] 2. This utility model, through the coordinated use of a support rod, a stabilizing rod, a limiting plate, and a first compression spring, ensures that when the sampling drill bit continuously rotates and enters the building interior, the right side of the dust cover adheres to the building surface. Due to the obstruction of the building, the dust cover moves to the left, causing the stabilizing rod to move to the left. The pressure generated by the first compression spring squeezes the left side of the dust cover, ensuring that the right side remains tightly adhered to the building surface. This prevents the right side of the dust cover from moving away from the building surface and affecting the dustproof effect. Attached Figure Description

Detailed Implementation

[0021] 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.

[0022] like Figures 1 to 4 As shown, this utility model provides a sampling device for building quality testing, including a housing 1. A main rod 2 is fixedly connected to the left side of the housing 1. Handles 3 are fixedly connected to both the front and rear sides of the left end of the main rod 2. A dust cover 4 is slidably connected to the right side of the housing 1. Stabilizing mechanisms 5 are fixedly connected to the upper and lower sides of the left side of the dust cover 4. The left end of the stabilizing mechanism 5 is fixedly connected to the surface of the housing 1. A drive motor 6 is slidably connected to the left side inside the housing 1. A protective net 7 is fixedly connected to the right side of the housing 1. The drive motor 6 outputs... The sampling drill bit 8 is fixedly connected to the right side of the protective net 7 at the outlet end and located inside the dust cover 4. Several fan blades 9 located inside the chassis 1 are fixedly connected to the left side of the output end surface of the drive motor 6. A Velcro female 10 is fixedly connected to the right side of the inner surface of the dust cover 4. A water-absorbing cotton sleeve 11 is provided on the right side inside the dust cover 4. A Velcro male 12 is fixedly connected to the outer surface of the water-absorbing cotton sleeve 11. The outer surface of the water-absorbing cotton sleeve 11 is movably connected to the inner wall of the dust cover 4 through the Velcro male 12 and the Velcro female 10.

[0023] refer to Figure 1The stabilizing mechanism 5 includes a support rod 13 fixedly connected to the top and bottom of the chassis 1. The end of the support rod 13 away from the chassis 1 has a through-hole, and a stabilizing rod 14 is slidably connected inside the hole. The right end of the stabilizing rod 14 is fixedly connected to the left side of the dust cover 4, and the left end of the stabilizing rod 14 is fixedly connected to a limiting piece 15. A first compression spring 16 is sleeved on the surface of the stabilizing rod 14. The right end of the first compression spring 16 is fixedly connected to the left side of the dust cover 4, and the left end of the first compression spring 16 is fixedly connected to the right side of the support rod 13.

[0024] As a technical optimization of this utility model, by setting up the support rod 13, the stabilizing rod 14, the limiting plate 15 and the first compression spring 16 in cooperation, when the sampling drill bit 8 continues to rotate and enters the building, the right side of the dust cover 4 is in contact with the building surface. Due to the obstruction of the building, the dust cover 4 moves to the left as a whole, which drives the stabilizing rod 14 to move to the left. The pressure generated by the first compression spring 16 squeezes the left side of the dust cover 4, so that the right side can always be in close contact with the building surface, avoiding the situation where the right side of the dust cover 4 moves away from the building surface and affects the dustproof effect.

[0025] refer to Figure 1 A hinge seat 17 is slidably connected to the right side of the bottom of the main rod 2. An electric telescopic rod 18 is movably connected inside the hinge seat 17 by bolts. A rubber pad 19 is fixedly connected to the bottom end of the electric telescopic rod 18.

[0026] As a technical optimization of this utility model, by setting the hinge seat 17, the electric telescopic rod 18 and the rubber pad 19 together, the length of the electric telescopic rod 18 can be adjusted according to the height of the drilling mark, so that the bottom of the rubber pad 19 contacts the ground. After the height of the electric telescopic rod 18 is adjusted, the bolt can be tightened so that the electric telescopic rod 18 is perpendicular to the main rod 2. When the device drills, the main rod 2 moves to the right, the hinge seat 17 slides at the bottom of the main rod 2, and the positions of the rubber pad 19 and the electric telescopic rod 18 remain unchanged, which provides support for the left end of the device, reduces the user's physical exertion, and makes it more convenient for the user to use.

[0027] refer to Figure 2 A stabilizing ring 20 is fixedly connected to the surface of the drive motor 6. The outer surface of the stabilizing ring 20 is slidably connected to the inner wall of the housing 1. A buffer pad 21 is fixedly connected to the left side of the drive motor 6. A second compression spring 22 is fixedly connected to the left side of the buffer pad 21. The left end of the second compression spring 22 is fixedly connected to the left side of the inner wall of the housing 1.

[0028] As a technical optimization of this utility model, by setting a stabilizing ring 20, a buffer pad 21 and a second compression spring 22 in combination, when the drive motor 6 starts and drives the sampling drill bit 8 to drill and sample, the sampling drill bit 8 will vibrate when it comes into contact with a hard building body. The second compression spring 22 and the buffer pad 21 can absorb and attenuate the vibration, reduce the impact of vibration on the drive motor 6, and avoid damage to the drive motor 6 due to vibration.

[0029] refer to Figure 4 A bearing 23 is fixedly connected to the left side of the output end surface of the drive motor 6. Support plates 24 are fixedly connected to the four sides of the right side inside the housing 1. A sliding sleeve 25 is fixedly connected to the inner side of the support plate 24. The surface of the bearing 23 is slidably connected to the inner wall of the sliding sleeve 25.

[0030] As a technical optimization of this utility model, the bearing 23, the support plate 24 and the sliding sleeve 25 are used in combination to support and protect the output end of the drive motor 6. When the device is running, the bearing 23 slides left and right inside the sliding sleeve 25, and the output end of the drive motor 6 rotates inside the bearing 23, so that the output end of the drive motor 6 can always be on the same axis as the sampling drill bit 8, avoiding the situation where the output end of the drive motor 6 swings when rotating, which would affect the rotation of the sampling drill bit 8.

[0031] refer to Figure 4 T-shaped blocks 26 are fixedly connected to the top and bottom of the left side of the dust cover 4. T-shaped grooves 27 that cooperate with the T-shaped blocks 26 are opened on the top and bottom of the chassis 1. The surface of the T-shaped blocks 26 is slidably connected to the inner wall of the T-shaped grooves 27.

[0032] As a technical optimization of this utility model, the T-shaped block 26 and the T-shaped groove 27 are used together to reinforce and limit the dust cover 4, so that the dust cover 4 can only slide on the right side of the surface of the chassis 1, and at the same time, it prevents the dust cover 4 from falling off the right side of the chassis 1 and affecting normal use.

[0033] The working principle and usage process of this utility model are as follows: The absorbent cotton sleeve 11 is removed from the inside of the dust cover 4 and then immersed in water to fully absorb moisture. The absorbent cotton sleeve 11 is then attached to the inside of the dust cover 4 using the Velcro female and male attachments 12. The length of the electric telescopic rod 18 can be adjusted according to the height of the marked point, ensuring the rubber pad 19 contacts the ground. The dust cover 4 and the sampling drill bit 8 are then aligned with the marked point for sampling. The user holds the handle 3 and pushes the device to the right, making the dust cover 4 fit against the building surface. Continuing to push the device brings the sampling drill bit 8 into contact with the building. The drive motor 6 is then started to rotate the sampling drill bit 8 for drilling and sampling. When motor 6 starts, it drives fan blade 9 to rotate inside the casing 1, generating airflow inside the dust cover 4 to lift dust generated during drilling. Simultaneously, the protective net 7 prevents cement debris from entering the casing 1 and affecting the operation of the drive motor 6. Because the absorbent cotton sleeve 11 fully absorbs moisture, dust is adsorbed onto its surface when in contact with it. After absorbing moisture, the absorbent cotton sleeve 11 drips water onto the surface of the sampling drill bit 8 as it rotates, reducing drill bit wear. This effectively prevents dust generation during sampling, providing dust protection. Furthermore, the cooling treatment of the drill bit during drilling and sampling reduces drill bit wear and extends the lifespan of the device.
