Description

Technical Field

[0001] This utility model relates to the assembly and connection of pagoda connectors and pipe fittings, and more particularly to a quick-connect device for pagoda connector pipes. Background Technology

[0002] In current automotive production, various high and low pressure oil pipes, air pipes, water pipes, automotive air conditioning pipes, automotive power steering pipes, oil pipes, and gasoline supply pipes are equipped with pagoda connectors at their ends to facilitate the connection between these pipes and corresponding accessories. These pipes are made of rubber, which is elastic but relatively hard. (See attached instruction manual.) Figure 5 As shown, the diameter of these pipe fittings is mostly between φ8mm and φ10mm. The pagoda connector is fitted onto the end of the pipe fitting. To facilitate the fitting of the pagoda connector into the pipe fitting end, a beveled guide surface is provided on the outer wall of the front end of the pagoda connector. The function of this beveled guide surface is to help the pagoda connector be smoothly inserted into the pipe fitting end. For good sealing, the pagoda connector and the inner wall of the pipe fitting are tightly fitted. However, the current fitting and assembly of the pagoda connector and the pipe fitting mainly relies on manual operation. The pagoda connector is manually inserted into the end of the pipe fitting. Because the pagoda connector and the inner wall of the pipe fitting are tightly fitted, it is difficult to press it in manually. It requires a lot of force. In addition, a rubber hammer is also needed to tap the pagoda connector to make it enter the pipe fitting. Since the force cannot be controlled, excessive external force will cause damage to the inside of the water pipe, affecting product quality, wasting manpower, and having low processing efficiency and increased production costs.

[0025] Example

[0026] Please refer to the instruction manual attached. Figure 1 and 2 As shown, the instruction manual is attached. Figure 1 and 2 The image shows a specific implementation example of a pagoda-shaped connector quick-connect device for pipelines, used as described in the appendix to the specification. Figure 5The pagoda-shaped connector 6 and the pipe fitting 7 are connected by a sleeve. This pagoda-shaped connector quick-connect device has a base 1 made of a profile, which is readily available and facilitates the assembly of bolts and screws, making component assembly convenient. A quick-pressing device that can move left and right is provided on the top of the base 1 near the right end. (See the attached instruction manual.) Figure 4 As shown, the quick-pressing device consists of a first push-pull clamp 3 and a quick-pressing head 31 disposed at the end of a first spindle 32 on the first push-pull clamp 3. It should be noted that existing push-pull clamps mainly consist of a fixed base, a spindle sleeved and connected to a movable base, and a movable handle hinged to the fixed base and connected to the spindle via a transmission mechanism. The movable handle can push the spindle to extend or retract relative to the fixed base. In this embodiment, the first push-pull clamp 3 is fixedly mounted on the base 1 via a base plate 11. The first push-pull clamp 3 is fixedly connected to the base plate 11 by bolts, and the base plate 11 is mounted on the base 1 by bolts. The first spindle 32 is arranged laterally along the length of the base 1, and is vertically parallel to the base 1. The handle on the first push-pull clamp 3 can operate the first spindle 32 to the left and right. The first mandrel 32 has a threaded hole 321 at the center of its end face. The quick-press head 31 consists of a top head 311 and a screw 312. The screw 312 is fixedly mounted on the center of the back of the top head 311, forming a T-shape. The top head 311 is used to push the pagoda connector 6 into the pipe fitting 7. The screw 312 is threaded into the threaded hole 321. The top head 311 is connected to the first mandrel 32 via the screw 312. Rotating the top head 311 can move and adjust the screw 312 within the threaded hole 321, thereby adjusting the left and right position of the top head 311 and facilitating the adjustment of the force applied to the pagoda connector 6. A support block 5 is fixedly connected to the top of the base 1 near its left end. The support block 5 corresponds left and right to the quick-press head 31. (See attached instruction manual). Figure 3 and 4As shown, the support block 5 consists of a fixed block 51 and a bracket 52. The fixed block 51 is fixedly installed on the base 1 by bolts. The bracket 52 is set on the top of the fixed block 51 and is welded or integrally formed. The top of the bracket 52 is provided with a groove 521 that opens upward and extends through its left and right ends. The end face of the groove 521 is V-shaped. The pipe fitting 7 with a pagoda connector 6 is placed on the groove 521 of the support block 5 (here, the pipe fitting 7 with the pagoda connector 6 is pre-fitted onto the end of the pipe fitting 7, but the two are not completely squeezed and inserted together). It should be noted that the pagoda connector 6 pre-installed at the end of the pipe fitting 7 placed on the groove 521 corresponds to the top head 11, and the center of the end of the pagoda connector 6 corresponds left and right to the center of the end of the top head 11. A bracket 2 with a "Π" structure at the end face is provided above the support block 5. The two sides of the bracket 2 are aligned with the front and rear sides of the base 1. The bracket 2 is bolted together and has a locking device on its top that can move up and down. Specifically, the locking device consists of a second push-pull clamp 4 and a lock head 41. The second push-pull clamp 4 is a conventional push-pull clamp, which is vertically fixed to the top of the bracket 2. The second spindle 43 of the second push-pull clamp 4 is vertically arranged and extends downward through the top of the bracket 2 and into the bracket 2. It should be noted that the top of the bracket 2 has a connecting hole that connects the top and bottom. The second spindle 43 passes through the connecting hole and is clearance-fitted with the connecting hole. The handle of the second push-pull clamp 4 can drive the second spindle 43 to move up and down. The lock head 4 is located inside the bracket 2, and its top is fixedly connected to the lower end of the second spindle 43. The lock head 4 corresponds vertically to the support block 5. The second spindle 43 can drive the lock head 4 to move up and down. See the appendix of the instruction manual. Figure 3As shown, the bottom of the lock head 41 is provided with a downward-facing slot 411 that extends through both its left and right ends. The end face of the slot 411 has an inverted "V" shape. The lock head 411 corresponds vertically to the slot 521. The downward-facing slot 411 can clamp and fix the pipe 7 placed in the bracket 521. In order to accommodate the clamping and fixing of pipes 7 of different diameters, the volume of the lock head 41 is smaller than the volume of the bracket 52. It can extend downward into the bracket 521. Furthermore, the top of the slot 411 and the bottom of the bracket 521 are both arc-shaped structures. This arc-shaped structure can better cooperate with the pipe 7 and avoid damaging the pipe 7. In order to finely adjust the height position of the lock head 41 on the second spindle 43 and ensure the best clamping effect of the lock head 41 on the pipe 7, a threaded adjustment hole is provided at the center of the lower end of the second spindle 43. An adjustment bolt 42 is provided in the threaded adjustment hole and is threadedly engaged with it. Rotating the adjustment bolt 42 can adjust its position in the threaded adjustment hole. The lock head 41 is fixedly connected to the lower end of the adjustment bolt 42. In order to ensure that the slot 411 at the bottom of the lock head 4 corresponds vertically with the slot 521 below, an adjustment screw 421 is screwed onto the outside of the adjustment bolt 42 to position it. After the adjustment screw 421 is adjusted to the approximate height position and the slot 411 at the bottom of the lock head 4 corresponds vertically with the slot 521, rotating the adjustment screw 421 can tighten the position of the adjustment bolt 42 on the second spindle 43.

[0027] In use, first, the pagoda connector 6 is embedded in the port of the end of the water pipe 7. Then, the pipe fitting 7 is placed in the groove 521. The locking head 41 is pushed downward by the second push-pull clamp 4. The locking head 4 clamps the pipe fitting 7 in the groove 521 and fixes it in place. Then, the first push-pull clamp 3 is pushed, and the quick-pressing head 31 is driven to move towards the support block 5 by the first spindle 32. The top head 311 pushes the corresponding pagoda connector 6 smoothly into the port of the pipe fitting 7, thus realizing the assembly of the pagoda connector 6 on the pipe fitting 7.

[0028] This pagoda-shaped connector quick-connect device has a simple structure and is easy to operate. It can be operated by a single person, saving labor costs and improving the assembly efficiency between the pipe fitting 7 and the pagoda connector 6. The insertion force between the pagoda connector 6 and the pipe fitting 7 is controlled, ensuring that the inner wall surface of the pipe fitting 7 port will not be damaged, thus improving the assembly quality of the product.

[0029] It should be emphasized that the above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
