The movable bracket 4 and the spring 5 are both located in the receiving cavity. By arranging the movable bracket 4 and the spring 5 in the receiving cavity to play a protective role, the service life of the movable bracket 4 and the spring 5 is extended, and the stability of the pipe pack rebound device is improved.

[0065] The first connecting component 32 corresponds to the spring 5 one by one, the first connecting component 32 is connected to the side of the baffle body 31 facing the spring 5, and the first connecting component 32 is integrally formed with the baffle body 31, the movable bracket 4 includes a bracket body 41 and at least one second connecting component 42, the bracket body 41 is slidably disposed on the bottom plate 1, the second connecting component 42 corresponds to the spring 5 one by one, the second connecting component 42 is connected to the bracket body 41, and the second connecting component 42 is integrally formed with the bracket body 41, and the two ends of the spring 5 are respectively connected to the first connecting component 32 and the second connecting component 42.

[0066] By integrating the first connecting component 32 with the baffle body 31 and integrating the second connecting component 42 with the bracket body 41, the baffle 3 and the movable bracket 4 do not need to be assembled and connected by bolts, etc., thereby saving the installation time of the pipeline pack rebound device. Moreover, the baffle 3 and the movable bracket 4 are both processed by casting. Since castings have a wide range of applications and are not limited by size, shape, and weight, parts with complex shapes can be produced. Therefore, only the baffle 3 and the movable bracket 4 need to be processed and manufactured, and there is no need to process and manufacture connecting components, bolts, and other parts separately. Compared with conventional machining processes, the number of parts is reduced, the number of parts of the pipeline pack rebound device is effectively reduced, the installation time of the pipeline pack rebound device is saved, and the cost is reduced.

[0071] The mounting member 33 has a mounting groove 331, and the rubber body is embedded in the mounting groove 331. One end of the rubber body will be embedded in the mounting groove 331, and the other end of the rubber body will be exposed outside the mounting groove 331, so that the rubber body is very convenient to install, and the structure is simple and easy to process.

[0073] The spring 5 needs to be sleeved on the second connecting part 42 and connected with the second connecting part 42. When the mobile bracket 4 and the spring 5 are assembled, the spring 5 will pass through the second guide part 421 and the second blocking part 422 and sleeved on the second connecting part 423. The second blocking part 422 will be tightly pressed against the spring 5 and prevent the spring 5 from escaping from the second connecting part 423, thereby realizing the connection between the mobile bracket 4 and the spring 5. The second guide surface of the second guide part 421 plays a guiding role, which is convenient for the passage of the spring 5. The structure is simple, the installation is convenient, and the stability is high. In this embodiment, the shape of the second guide part 421 is truncated cone. The structure is simple and the processing and manufacturing are convenient.

[0074] The outer surface of the second connecting member 42 has a second notch 424, which is recessed radially inward from the outer surfaces of the second blocking portion 422 and the second connecting portion 423 and is located in the second guide portion 421. When the movable bracket 4 and the spring 5 are assembled, the spring 5 will pass through the second guide portion 421 to facilitate passing, and then the second notch 424 will facilitate the spring 5 to pass through the second blocking portion 422 and be snap-connected with the second connecting portion 423, so that the installation is very convenient.

[0075] The pipeline package rebound device also includes a fixed seat bracket 6, the bottom of the fixed seat bracket 6 has a first protrusion 62 protruding downward, the fixed seat bracket 6 is provided with a through hole 61, the through hole 61 passes through the first protrusion 62 from the top surface of the fixed seat bracket 6, the end of the bracket body 41 is exposed outside the accommodating cavity, and the top surface of the end of the bracket body 41 has a positioning groove 411, the bracket body 41 is provided with a connecting hole 412, the connecting hole 412 passes through the bracket body 41 from the bottom of the positioning groove 411, the first protrusion 62 is inserted into the positioning groove 411, a fastener passes through the through hole 61 and is connected to the connecting hole 412, so as to realize the connection between the bracket body 41 and the fixed seat bracket 6.

[0076] When the fixed seat bracket 6 and the mobile bracket 4 are assembled, the fixed seat bracket 6 is inserted into the positioning groove 411 of the mobile bracket 4 through the first protrusion 62, so that there is no offset or misalignment between the fixed seat bracket 6 and the mobile bracket 4 during the assembly process, which greatly improves the installation accuracy of the pipeline pack rebound device; then the fastener is passed through the through hole 61 and connected to the connecting hole 412, so that the mobile bracket 4 is connected to the fixed seat bracket 6. Accurate positioning is achieved, and the stability of the pipeline pack rebound device is improved; at the same time, the installation is fast and convenient.

[0077] In this embodiment, the bottom of the bracket body 41 has a second protruding portion 413 protruding downward, and the connecting hole 412 penetrates the second protruding portion 413 from the bottom of the positioning groove 411. Since the second protruding portion 413 protrudes downward, the connecting hole 412 is arranged on the second protruding portion 413, so that the depth of the connecting hole 412 will be further lengthened, which effectively strengthens the connection area between the mobile bracket 4 and the fastener, and greatly improves the stability of the dresspack rebound device.

[0078] The shape of the connecting hole 412 is cylindrical, and the inner wall surface of the connecting hole 412 has an internal thread, which is connected to the fastener. In this embodiment, the fastener is a bolt, which passes through the through hole 61 and is connected to the internal thread of the connecting hole 412, thereby eliminating the use of nuts, facilitating installation and connection, and reducing costs. Among them, the inner diameter of the through hole 61 is greater than or equal to the inner diameter of the connecting hole 412. Preferably, the axis of the through hole 61 and the axis of the connecting hole 412 are located on the same straight line, which facilitates the installation and connection of the fixed seat bracket 6 and the mobile bracket 4.

[0079] In this embodiment, the through hole 61 includes a first hole 611 and a second hole 612. The first hole 611 is located on the second hole 612 and communicates with the top of the second hole 612. The bottom of the second hole 612 is inserted into the positioning groove 411 and communicates with the connecting hole 412. The bolt will pass through the first hole 611 and the second hole 612 in sequence and connect with the connecting hole 412. Among them, the shapes of the first hole 611 and the second hole 612 are both cylindrical, and the inner diameter of the first hole 611 is larger than the inner diameter of the second hole 612. It is easy to insert the bolt into the first hole 611, and then pass through the second hole 612 and connect with the connecting hole 412, which is very convenient to achieve installation and connection, thereby saving the installation time of the pipeline pack rebound device.

[0080] There are two first protrusions 62 and two through holes 61, which are respectively located at two ends of the fixed seat bracket 6. There are two connecting holes 412, which are respectively located at two ends of the mobile bracket 4.

The plate body 11 and the two positioning components 12 are processed by casting. Since castings have a wide range of applications and are not limited by size, shape, and weight, parts with complex shapes can be produced. Therefore, only the bottom plate 1 needs to be processed and manufactured, and there is no need to process and manufacture the plate body 11, the positioning components 12, etc. separately.
