[0022] 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.

[0023] Please see Figures 1 to 4This embodiment of a simple connection structure for a silencer includes a duct silencer 1, a ventilation duct 2 on the left side of the duct silencer 1, glass wool 3 and a sealing sleeve 4 on the duct silencer 1, and a simple connection structure on the duct silencer 1. The ventilation duct 2 and the left side of the duct silencer 1 are inserted into each other. The sealing sleeve 4 is installed on the outer surface of the duct silencer 1 and is tightly attached to the left side of the ventilation duct 2. There are two simple connection structures, which are respectively installed at the top and bottom of the duct silencer 1.

[0024] Example 1: Please refer to Figures 1 to 4 In this embodiment, the simplified connection structure includes a positioning frame 51 fixedly installed on the ventilation duct 2, a support plate 52 installed on the duct silencer 1, a support component 53 installed on the duct silencer 1 to limit the sliding trajectory of the support plate 52, and a feeding component 54 fixedly installed on the duct silencer 1 to control the left and right movement of the support plate 52. The feeding component 54 includes a mounting sleeve and a linear actuator, which are fixedly connected. The mounting sleeve is fixedly installed on the duct silencer 1, and the telescopic end of the linear actuator is fixedly connected to one side of the support plate 52. The telescopic movement causes the support plate 52 to move left and right. A support frame 55 is fixedly installed on the support plate 52. A connecting rod 56 is rotatably installed between the front and rear side walls of the inner cavity of the support frame 55. A hook 57 is rotatably installed on the outer surface of the connecting rod 56, with one end hooking the positioning frame 51. The hook 57 includes a hook-shaped plate and a connecting cylinder. The hook plate and the connecting cylinder are fixedly connected. The connecting cylinder is rotatably installed on the outer surface of the connecting rod 56. One end of the hook-shaped plate passes through the positioning frame 51. By using the cooperation between the hook plate and the positioning frame 51, the ventilation duct 2 and the duct silencer 1 are connected. A locking component is installed on the support plate 52.

[0025] The support component 53 includes two linear slide rails and two sliders. The two linear slide rails are fixedly installed on the pipe silencer 1, and the two sliders are fixedly connected to the support plate 52. The two linear slide rails are slidably installed with the two sliders respectively, which facilitates support and restricts the sliding of the support plate 52, and reduces the friction of the support plate 52 movement.

[0026] Using the above technical solution, the ventilation duct 2 and the left side of the duct silencer 1 are connected. The sealing sleeve 4 is tightly attached to the left side of the ventilation duct 2 to provide a seal. The linear actuator in the feeding component 54 is activated, and its telescopic end pushes the support plate 52 to move. Due to the cooperation of the linear slide rail and the slider in the support component 53, the support plate 52 can only move linearly left and right along the linear slide rail, moving closer to the ventilation duct 2. As the support plate 52 moves, the support frame 55 also moves accordingly. The hook 57 is rotatably installed on the connecting rod 56 inside the support frame 55. When the support plate 52 moves to the appropriate position, the hook plate of the hook 57 is rotated to hook one end onto the positioning frame 51, realizing a preliminary connection between the ventilation duct 2 and the duct silencer 1 to a certain extent.

[0027] Example 2: Please refer to Figures 1 to 4 In this embodiment, the locking component includes a locking box 58 fixedly installed on the support plate 52. A positioning block 59 is slidably installed inside the locking box 58, with one end penetrating through the support plate 52 and extending into the pipe silencer 1. An electric push rod 60 for controlling the up and down movement of the positioning block 59 is fixedly installed inside the locking box 58. The positioning block 59 includes a locking block and a guide plate, which are fixedly connected. The guide plate is slidably installed inside the locking box 58. The telescopic end of the electric push rod 60 is fixedly connected to the guide plate, so that the telescopic movement of the electric push rod 60 can drive the positioning block 59 up and down to achieve the tightening and loosening operation.

[0028] The support plate 52 has a through groove, and the pipe silencer 1 has a lock hole. One end of the locking block passes through the through groove and extends into the inside of the lock hole, so that the locking block can be inserted into the inside of the pipe silencer 1, thereby locking the ventilation duct 2 and the pipe silencer 1.

[0029] By adopting the above technical solution, the linear driver of the starting feed component 54 is realized. The contraction of the linear driver drives the hook 57 to hook the positioning frame 51 and squeeze it towards the ventilation duct 2. The locking component starts to work, and the electric push rod 60 in the locking box 58 is activated. Its telescopic end drives the guide plate to move. The guide plate is fixedly connected to the locking block, so that the locking block moves down along the through groove and is inserted into the locking hole on the duct silencer 1, fixing the support plate 52 relative to the duct silencer 1, and further enhancing the connection stability between the ventilation duct 2 and the duct silencer 1.

[0030] The working principle of the above embodiments is as follows:

[0031] The silencer has a simple connection structure. The ventilation duct 2 is inserted into the left side of the duct silencer 1. The sealing sleeve 4 is tightly attached to the left side of the ventilation duct 2 to provide a seal. The linear actuator in the feed component 54 is activated, and its telescopic end pushes the support plate 52 to move. Due to the cooperation of the linear slide rail and the slider in the support component 53, the support plate 52 can only move left and right along the linear slide rail, moving closer to the ventilation duct 2. As the support plate 52 moves, the support frame 55 also moves. The hook 57 is rotatably installed on the connecting rod 56 inside the support frame 55. When the support plate 52 moves to the appropriate position, the hook plate of the hook 57 is rotated to hook the positioning frame 51 at one end, realizing a preliminary connection between the ventilation duct 2 and the duct silencer 1 to a certain extent.

[0032] The linear drive of the feed component 54 is activated. The retraction of the linear drive drives the hook 57 to hook the positioning frame 51 and press it towards the ventilation duct 2. The locking component starts to work. The electric push rod 60 in the locking box 58 is activated. Its telescopic end drives the guide plate to move. The guide plate is fixedly connected to the locking block, so that the locking block moves down along the through groove and inserts into the locking hole on the duct silencer 1, fixing the support plate 52 relative to the duct silencer 1, and further strengthening the connection stability between the ventilation duct 2 and the duct silencer 1.
