Description

Technical Field

[0001] This utility model relates to the field of pipeline connection technology, and in particular to a water conservancy pipeline connection device. Background Technology

[0002] In water conservancy projects, plastic pipes are widely used due to their advantages such as corrosion resistance, light weight, and ease of installation. In order to take advantage of their thermoplasticity and achieve efficient and firm connections, these plastic pipes are connected by heat fusion, and heat fusion machines are used in the connection process.

[0003] Currently, existing hot melt machines use heating plates to melt and fuse pipe joints at high temperatures. Because the heating plates are very hot, they need time to cool down even after the connection is completed. During this process, if workers accidentally touch the pipe joints, they will be burned by the heating plates, posing a certain safety hazard. To address this issue, we propose a water pipe connection device. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a water conservancy pipeline connection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A water conservancy pipeline connection device includes a hot-melt machine body, a heating plate connected to the inner side of the hot-melt machine body, and heating heads symmetrically distributed on the front and back sides of the heating plate. Rotating plates are connected to the front and rear ends of the hot-melt machine body through bearings, and protective covers are provided on the side walls of the rotating plates. A slot is opened inside the hot-melt machine body, and a connecting spring is connected to the inner wall of the slot. The other end of the connecting spring is connected to a connecting plate, and an abutment block is connected to the upper side of the connecting plate.

[0007] Preferably, a limiting block is connected to the inner side of the abutment block, and a limiting groove adapted to the limiting block is provided inside the protective cover.

[0008] Preferably, there are two sets of limiting blocks and limiting grooves, and the two sets of limiting blocks and limiting grooves are symmetrically distributed about the central axis of the rotating plate.

[0009] Preferably, the inner wall of the slot is connected to a connecting rod, and the interior of the connecting plate is provided with a movable slot adapted to the connecting rod.

After the device is used, the rotating plate and the protective cover work together to shield the heating plate and heating head, effectively preventing workers from accidentally touching the high-temperature heating plate and thus preventing their skin from being burned. This effectively improves the safety of the device during use.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A water conservancy pipeline connection device includes a hot melt machine body 1. A heating plate 2 is connected to the inner side of the hot melt machine body 1, and heating heads 12 are symmetrically distributed on both sides of the heating plate 2. The connection method of the heating plate 2 and heating heads 12 to the pipeline is existing technology and will not be described in detail here. The front and rear ends of the hot melt machine body 1 are respectively connected to rotating plates 3 through bearings, and the side walls of the rotating plates 3 are provided with protective covers 4. Since the rotating plates 3 are connected to the hot melt machine body 1 through bearings, the rotation requirements of the rotating plates 3 can be met. The interior of the hot melt machine body 1 has a slot 5, and the inner wall of the slot 5 is connected to a connecting spring 6. The other end of the connecting spring 6 is connected to a connecting plate 7, and the upper side of the connecting plate 7 is connected to an abutment block 14. In use, the abutment block 14 and the limiting block 9 cooperate with each other to facilitate the operator to limit the rotating plate 3 when it is rotated to a suitable angle. The height of the rotating plate 3 and the protective cover 4 is greater than the height of the heating plate 2 to achieve the protection effect of the heating plate 2.

[0023] Furthermore, refer to Figure 3 It can be seen that the inner side of the abutment block 14 is connected to the limiting block 9, and the inside of the protective cover 4 is provided with a limiting groove that matches the limiting block 9. When the heating plate 2 needs to be used, the operator can rotate the rotating plate 3 and the protective cover 4 180 degrees and move them to the side of the handle of the hot melt machine body 1 to expose the heating plate 2 and the heating head 12. After use, the operator can rotate the protective cover 4 to the side wall of the heating plate 2 for protection. Through the cooperation of the limiting block 9 and the limiting groove, the limiting effect on the rotating plate 3 can be improved.

[0024] Furthermore, refer to Figure 3 It can be seen that there are two sets of limiting blocks 9 and limiting grooves, and the two sets of limiting blocks 9 and limiting grooves are symmetrically distributed about the central axis of the rotating plate 3. By opening the two sets of limiting blocks 9 and limiting grooves, the limiting effect on the rotating plate 3 can be further guaranteed.

[0025] Furthermore, refer to Figure 4 It can be seen that the inner wall of the slot 5 is connected to the connecting rod 8, and the inside of the connecting plate 7 is provided with a moving groove that matches the connecting rod 8. Through the setting of the connecting rod 8 and the moving groove, the lateral guiding operation of the connecting plate 7 can be realized, thereby ensuring the reliability of the lateral movement of the connecting plate 7.

[0026] Furthermore, refer to Figure 1 and Figure 3 It can be seen that the protective cover 4 has two sets of grooves symmetrically arranged inside, and both sets of grooves are equipped with mesh plates 11. During use, the mesh plates 11 will not affect the normal dissipation of airflow, so as to ensure the normal heat dissipation of the heating plate 2.

[0027] Furthermore, refer to Figure 3 It can be seen that the inner side of the rotating plate 3 is connected to the slide bar 10, and the end of the protective cover 4 is provided with a mating groove that matches the slide bar 10. The side wall of the protective cover 4 is connected to the slide bar 10 by bolts. During use, the T-shaped slide bar 10 and the mating groove cooperate with each other, so that the staff can easily remove the protective cover 4 from the side of the rotating plate 3. This allows the staff to regularly remove the protective cover 4 and the grid plate 11 for cleaning, thereby effectively improving the convenience of using the device. The bolts ensure the tightness of the connection between the rotating plate 3 and the protective cover 4, thus preventing the protective cover 4 from moving easily during the connection process.

[0028] Furthermore, refer to Figure 3 It can be seen that the protective cover 4 is set with a U-shaped structure, and the side walls of the protective cover 4 are symmetrically connected with rubber strips 13. When in use, because the protective cover 4 is set with a U-shape, it can achieve the protection effect of heating plate 2. With the setting of rubber strips 13, the edge of the protective cover 4 can be protected.

[0029] Working Principle: When using this utility model, the operator can first place the device in a suitable position, and then manually pull the abutment block 14 to drive the connecting plate 7 to slide along the inner wall of the slot 5. At this time, the limiting block 9 connected to the inner side of the abutment block 14 can be pulled out from the limiting groove opened inside the rotating plate 3 to release the limitation on the rotating plate 3. Then the operator can rotate the protective cover 4 so that it rotates 180 degrees together with the rotating plate 3. Then the operator can start the hot melt machine body 1 and use the multiple sets of heating heads 12 connected to the side wall of the heating plate 2 to heat the pipe interface, thereby facilitating the subsequent connection operation of the pipe. After use, the operator can pull the abutment block 14 again to rotate the protective cover 4 back to the side wall of the heating plate 2 to achieve the protection operation of the heating plate 2 and the heating head 12, thereby effectively preventing the operator from accidentally touching and being burned. The above is the complete working principle of this utility model.
