Description

Technical Field

[0001] The utility model relates to the technical field of inclinometer tubes, in particular to an inclinometer tube connection structure. Background Art

[0002] Inclinometer tubes are specially designed for underground pre-buried measurement. In actual engineering, they are usually used in conjunction with inclinometers to monitor deep soil displacement. This is also the most effective and intuitive monitoring method for reflecting deep soil deformation and displacement. Currently, this method has been widely used to monitor lateral displacement in tunnels, deep foundation pits, slopes, and the abutments, foundations, and bodies of concrete dams. During use, multiple inclinometer tubes usually need to be connected in series through a connecting structure.

[0003] In the prior art, when inclinometer tubes are installed and used, the most common method for connecting them to each other in engineering is sleeve connection, that is, the two inclinometer tubes are connected by a sleeve, and the sleeve and the inclinometer tube are fixed by self-tapping screws. However, the drilling force must be strictly controlled when drilling the inclinometer tube, otherwise it is very easy to cause the tube body to deform or even damage the inclinometer tube; at the same time, due to the influence of groundwater, the self-tapping screws are prone to corrosion, and groundwater, mud, etc. can easily enter the inclinometer tube along the gap, seriously affecting the monitoring accuracy of deep displacement, making it difficult to accurately measure the soil change value. Utility Model Content

[0004] The purpose of the utility model is to solve the problems in the prior art such as the complicated installation process of the inclinometer tube, the easy corrosion and loosening of the connection, the poor waterproof effect, and the decrease in stability and sealing after long-term use, and to propose an inclinometer tube connection structure.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An inclinometer tube connection structure includes an inclinometer tube body and a connecting sleeve sleeved on the outer wall of the connecting end of the inclinometer tube body. A plurality of groups of cantilevered elastic clips are evenly arranged on the outer wall of the inclinometer tube body. The inner walls at both ends of the connecting sleeve are provided with slots corresponding to the cantilevered elastic clips. The cantilevered elastic clips are engaged with the slots away from each other, and a sealing member is provided between the outer wall of the inclinometer tube body and the inner wall of the connecting sleeve.

[0007] In order to improve the waterproof sealing effect, preferably, the sealing member includes a first rubber pad and a second rubber pad, the first rubber pad is fixedly arranged on the outer wall of one end of the inclinometer tube body, and the second rubber pad is respectively fixedly arranged on the inner walls of both ends of the connecting sleeve, and the outer wall of the first rubber pad is against the inner wall of the second rubber pad.

[0008] In order to ensure a reliable connection between the inclinometer tube body and the connecting sleeve, preferably, a plurality of groups of guide bars are fixedly provided on the outer wall of the inclinometer tube body, and the plurality of groups of guide bars extend along the axis of the inclinometer tube body. Guide grooves corresponding to the guide bars are provided on the inner walls at both ends of the connecting sleeve, and the guide bars are slidably arranged in the guide grooves.

[0009] In order to facilitate the snap connection between the cantilevered elastic clip and the slot, a receiving slot is further provided at the bottom of the guide bar, one end of the cantilevered elastic clip is fixedly arranged on the inner top of the receiving slot, and the slot is provided on the inner wall of the guide slot.

[0010] Preferably, the cantilever elastic buckle is made of polypropylene plastic.

[0011] Preferably, the connecting sleeve is made of polyvinyl chloride.

[0012] Compared with the prior art, the present invention provides an inclinometer casing connection structure with the following beneficial effects:

[0013] 1. This inclinometer tube connection structure inserts the connecting ends of two inclinometer tube bodies into the connecting sleeve. Once properly connected, the cantilevered elastic buckle on the inclinometer tube body precisely engages with the slot on the inner wall of the connecting sleeve, facilitating quick connection of the inclinometer tube and improving work efficiency. Furthermore, a seal is provided between the outer wall of the inclinometer tube body and the inner wall of the connecting sleeve to prevent external liquids such as groundwater, rainwater, and mud from penetrating into the inclinometer tube body, improving waterproof performance and thereby ensuring the accuracy and reliability of monitoring data.

[0014] 2. This inclinometer tube connection structure, by fixing a guide bar on the outer wall of the inclinometer tube body, can ensure a reliable connection between the inclinometer tube body and the connecting sleeve, improve the connection strength, and avoid circumferential sliding between the connecting sleeve and the inclinometer tube body, which would cause torsional deformation of the cantilevered elastic buckle and shorten its service life. It can also improve the torsional strength of the inclinometer tube body itself.

[0015] The parts not mentioned in this device are the same as the existing technology or can be implemented by using the existing technology. The utility model inserts the connecting ends of the two inclinometer tube bodies into the connecting sleeve respectively. After being inserted into place, the cantilevered elastic buckle on the inclinometer tube body is just engaged with the groove on the inner wall of the connecting sleeve, which facilitates the rapid connection of the inclinometer tube.

[0023] Example:

[0024] Reference Figures 1-4A connecting structure for an inclinometer tube includes an inclinometer tube body 1 and a connecting sleeve 8 sleeved on the outer wall of the connecting end of the inclinometer tube body 1. When in use, the connecting ends of the two inclinometer tube bodies 1 are respectively inserted into the connecting sleeve 8. After being plugged into place, the cantilever elastic buckle 3 on the inclinometer tube body 1 is just engaged with the card groove 6 on the inner wall of the connecting sleeve 8 to realize the series connection of the two inclinometer tube bodies 1, facilitate the rapid connection of the inclinometer tubes, and improve work efficiency. The material of the connecting sleeve 8 is polyvinyl chloride, that is, PVC Tube, multiple groups of cantilever elastic buckles 3 are evenly arranged on the outer wall of the inclinometer tube body 1, and the cantilever elastic buckles 3 are provided with two to eight groups. Here, we prefer four groups, which are evenly distributed on the outer wall of the connecting end of the inclinometer tube body 1 in a circular shape. The inner walls of both ends of the connecting sleeve 8 are provided with card grooves 6 corresponding to the cantilever elastic buckles 3, that is, the inner walls of both ends of the connecting sleeve 8 are provided with four groups of card grooves 6 corresponding to the cantilever elastic buckles 3, and the cantilever elastic buckles 3 are kept away from the card grooves 6 for engagement, and A sealing member is provided between the outer wall of the inclinometer tube body 1 and the inner wall of the connecting sleeve 8. By providing the sealing member between the inclinometer tube body 1 and the connecting sleeve 8, the waterproof sealing effect can be improved, and the entry of groundwater or mud into the inclinometer tube body 1 along the gap can be reduced, thereby reducing the impact on the monitoring accuracy of deep displacement. During the connection process, the inclinometer tube body 1 is pressed into the connecting sleeve 8 in the direction in which the guide bar 2 and the guide groove 7 match. At this time, the four groups of cantilevered elastic buckles 3 are squeezed by the inner wall of the guide groove 7 and tilted toward the receiving groove. , and enters the guide groove 7 along with the guide bar 2 until it reaches the bottom end of the guide groove 7. At this time, the cantilever elastic buckle 3 reaches the position of the card slot 6 and is no longer squeezed by the inner wall of the guide groove 7. It automatically pops out into the card slot 6 and locks, realizing the rapid connection of the inclinometer tube body 1; at the same time, a seal is provided on the outer wall of the inclinometer tube body 1 and the inner wall of the connecting sleeve 8 to prevent external liquids such as groundwater, rainwater, mud, etc. from penetrating into the interior of the inclinometer tube body 1, thereby improving the waterproof performance and thus ensuring the accuracy and reliability of the monitoring data.

[0025] Reference Figure 2 and Figure 4 Here, we design the sealing member as a first rubber pad 4 and a second rubber pad 5. The first rubber pad 4 is fixedly arranged on the outer wall of the connecting end of the inclinometer tube body 1, and the second rubber pad 5 is respectively fixedly arranged on the inner walls of both ends of the connecting sleeve 8. Here, we use waterproof glue to fix the first rubber pad 4 and the second rubber pad 5 on the outer wall of the inclinometer tube body 1 and the inner wall of the connecting sleeve 8, and the outer wall of the first rubber pad 4 is abutted against the inner wall of the second rubber pad 5. When in use, by fixing the first rubber pad 4 on the outer wall of the connecting end of the inclinometer tube body 1 and fixing the second rubber pad 5 in the connecting sleeve 8, the outer wall of the first rubber pad 4 is fitted with the inner wall of the second rubber pad 5 to achieve a tight connection and improve the waterproof effect.

[0026] Reference Figure 1 and Figure 2 A plurality of guide strips 2 are fixedly provided on the outer wall of the inclinometer tube body 1. The guide strips 2 are provided in two to eight groups, preferably four groups. The four groups are evenly distributed on the outer wall of the inclinometer tube body 1 in a circumferential manner. The plurality of guide strips 2 extend along the axial direction of the inclinometer tube body 1. Guide grooves 7 corresponding to the guide strips 2 are provided on the inner walls of both ends of the connecting sleeve 8. The guide strips 2 are slidably provided in the guide grooves 7. When in use, by fixing the guide strips 2 on the outer wall of the inclinometer tube body 1, on the one hand, a reliable connection between the inclinometer tube body 1 and the connecting sleeve 8 can be ensured, the connection strength can be improved, and circumferential sliding between the connecting sleeve 8 and the inclinometer tube body 1 can be avoided, which would cause torsional deformation of the cantilevered elastic buckle 3 and affect the service life. In addition, the torsional strength of the inclinometer tube body 1 itself can be improved.

[0027] Reference Figure 2-Figure 4 A receiving groove is provided at the bottom of the guide bar 2, one end of the cantilevered elastic clip 3 is fixedly set on the inner top of the receiving groove, and the clip groove 6 is provided on the inner wall of the guide groove 7. When in use, by fixing the cantilevered elastic clip 3 on the guide bar 2, the impact on the overall structure and strength of the inclinometer casing body 1 can be reduced, and the processing is more convenient, thereby improving the use effect.

[0028] Reference Figure 4 The material of the cantilever elastic buckle 3 is polypropylene plastic or polyethylene. Here, we prefer polypropylene plastic, and the material of the inclinometer tube body 1 is also preferably polypropylene plastic. During the processing, the production difficulty can be reduced and the production efficiency can be improved.

[0029] In this utility model, when the inclinometer tube body 1 is constructed with an outer diameter of 70 mm, the connecting sleeve 8 is constructed with an outer diameter of 80 mm PVC pipe. To ensure reliable connection strength, the cantilevered elastic buckle 3 is preferably 15 mm long, 4 mm wide, and 2 mm thick. The bottom portion that enters the slot 6 is designed as a trapezoidal shape with a height of 3 mm and a depth of 3 mm. This design offers a simple structure, easy installation, and low manufacturing cost. Once connected, it effectively prevents the inclinometer tube from separating and effectively prevents rainwater and mud from entering the interior of the inclinometer tube during construction, ensuring more accurate and reliable monitoring data.
