[0015] 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.
[0016] Please see Figures 1-6 The present invention provides the following technical solution: To address the problems of existing muffler housing placement racks, which are typically used in muffler housing production and are mostly rigidly fixed, making it inconvenient to adjust the placement height of the muffler housings and to support muffler housings of different sizes, this solution provides an adjustable muffler housing placement rack. The rack includes a support column 1, a fixed column 2, and a placement plate 10. The height adjustment mechanism consists of a movable horizontal column 4 that moves up and down above the support column 1, movable connecting sleeves 5 fixed at the front and rear ends of the movable horizontal column 4, and a connecting rod 9 fixed at the right end of the movable connecting sleeves 5. The height adjustment mechanism drives the connecting rod 9 to form a lifting structure above the support column 1. The adjustable length support mechanism consists of a placement block 11 that moves back and forth at the upper end of the placement plate 10, a linear guide rail 13 inserted into the middle of the placement block 11, and a movable rod 14 fixed at the lower end of the placement block 11. An anti-slip pad 12 is provided at the upper end of the placement block 11. like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a fixed column 2 is welded to the upper end of the support column 1, and the fixed columns 2 at both ends are connected by a connecting column 3. The placement plate 10 is set above the support column 1. First, the height of the connecting rod 9 can be adjusted by pulling the horizontal column 4 up or down. The horizontal column 4 causes the movable connecting sleeve 5 to slide up and down with the fixed column 2. The horizontal column 4, together with the movable connecting sleeve 5 and the connecting rod 9, moves up and down on the placement plate 10 at the upper end of the support column 1, which facilitates the adjustment of the placement height of the muffler housing. After the height adjustment is completed, the movable limiting sleeve 6 is moved. The movable limiting sleeve 6 slides on the outside of the movable horizontal column 4. The lower end of the movable limiting sleeve 6 is inserted into the fixing hole 8 at the corresponding position on the inner side of the fixed column 2 to limit the movement between the movable connecting sleeve 5 and the fixed column 2, thereby fixing the placement plate 10. Then, the fixing bolt 7 is rotated to limit the movement between the movable limiting sleeve 6 and the movable horizontal column 4. Based on the length of the muffler housing, such as Figure 1 , Figure 5 and Figure 6As shown, by pulling down the fixed plate 16, the fixed plate 16 slides against the movable rod 14, and the fixed plate 16 compresses the spring 15 downwards, causing the spring 15 to undergo elastic deformation. The middle part of the fixed plate 16 moves out of the connecting hole 17, thereby releasing the restriction between the movable rod 14 and the placement plate 10. Then, by pulling the movable rod 14, the movable rod 14 slides in the placement plate 10. At the same time, the movable rod 14 drives the placement block 11 to slide back and forth between the linear guide rail 13, thereby enabling the placement block 11 to be moved at both ends. The spacing between the bodies is adjusted to facilitate support for muffler housings of different sizes. After adjustment, the fixing plate 16 is released directly. At this time, the spring 15 returns to its elastic deformation, pushes the fixing plate 16 upward and inserts it into the corresponding connecting hole 17, limiting the movement between the movable rod 14 and the placement plate 10. Then, the muffler housing is placed on the placement block 11. At the same time, the upper end of the placement block 11 is provided with an anti-slip pad 12, which contacts the muffler housing to avoid scratching the muffler housing.
[0017] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
