Description

Technical Field

[0001] The utility model relates to the technical field of dust collector frames, in particular to a multi-section U-shaped frame connecting joint for a bag dust collector. Background Art

[0002] At present, when connecting the multi-section circular skeleton of the dust collector on the market, a rotary joint can be used as a connecting device, and it has a self-adjusting function for verticality. However, it is difficult to implement this form of rotation on the U-shaped skeleton. Therefore, the U-shaped skeleton joint is mainly connected by a guide plate and a buckle. Figure 1 As shown, this method uses a lot of accessories in production, has high requirements for welding technology, and during installation, the installation steps are relatively cumbersome, the processing size requirements are many, and it cannot self-adjust the verticality during use. In particular, the configuration skeleton size is long, generally 2 or 3 sections, connected by connectors. Since the connectors are manually welded, there are certain errors, which affects the verticality of the skeleton after installation, resulting in most of the skeleton bottoms contacting each other, resulting in collision wear during use and causing premature wear of the filter bag. Therefore, it is necessary to develop a connector that can reduce accessories, facilitate welding, easy installation, and easy adjustment, so that the verticality of the skeleton is not affected, thereby extending the service life of the matching filter bag.

[0018] The utility model is further described below.

[0019] Refer to the attached Figure 1-7 A multi-section skeleton connection joint for a bag dust collector includes a male part 1 and a female part 2. A self-locking part 12 is provided in the middle of the upper end of the male part 1, slots 11 are symmetrically provided on both sides of the male part 1, and plug-in parts 21 are symmetrically provided on the inner edges of both sides of the female part 2. The male part 1 and the female part 2 are plug-in connected through the plug-in parts 21 and the slots 11, and self-locking is achieved through the self-locking part 12.

[0020] In this preferred embodiment, the self-locking portion 12 includes a connecting portion A121, a stepped portion 122, and a bending portion 123. A connecting portion B23 is provided on the female component 2. The connecting portion B23 corresponds to the connecting portion A121 and is self-locked by bending the bending portion 123.

[0021] In this preferred embodiment, hollow portions 22 are symmetrically provided on both sides of the connecting portion B23.

[0022] In this preferred embodiment, the male component 1 and the female component 2 are connected in parallel.

[0023] In this preferred embodiment, a limiting protrusion 111 is provided at the end of the slot 11 .

[0024] During specific implementation, the male part 1 and the female part 2 are respectively located at the ends of the multi-section U-shaped skeleton. When connection is required, the plug-in part 21 on the female part 2 is inserted parallel to the slot 11 on the male part 1, and the position is limited by the limiting protrusion 111, and then the bending part 123 is bent to lock it. The material of the joint workpiece includes but is not limited to Q235 carbon steel, 304, 316L stainless steel, etc., with a thickness of 1-2mm. After the joint workpiece is connected, the gap between the male and female parts is 1-5mm. The gap of 1-5mm refers to the distance that can be naturally pulled vertically apart by its own weight after the connection is tightened, which facilitates the flexible self-adjustment of the skeleton in a naturally suspended state. If the gap is less than 1mm, it is difficult to install; if the gap is greater than 5mm, the installation is not tight and it is easy to shake in the operating state, causing wear on the filter bag and causing the connector to wear out and fail, bringing risks of use. The manufacturing methods of the joint workpiece include but are not limited to stamping, casting, etc. The self-locking function after the joint workpiece is connected does not limit the unilateral step self-locking design. The use of the above-mentioned multi-section U-shaped frame connection joint of the bag dust collector is more convenient in the production and processing of the frame. When installing multiple sections, the filter bag frame can be connected by simply plugging it in. It also has a self-adjusting function for verticality, which can better improve the verticality of the frame and extend the service life of the frame and bag.

[0025] The above embodiments of the present invention are merely examples to clearly illustrate the present invention, but are not intended to limit the scope of protection of the present invention. All equivalent technical solutions also fall within the scope of the present invention. The scope of patent protection of the present invention should be defined by the claims.
