Dust Collector Barrel Buckle Mechanism for Quick Bag Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The replacement of dust collecting bags in bag-type dust collectors is cumbersome and time-consuming, requiring significant space and effort, which complicates the process and reduces user convenience.
Innovation Solution
A buckle mechanism is introduced, comprising a first retaining seat, second retaining seat, linking members, connecting rods, and a support unit with elastic members, allowing for easy assembly and disassembly of the dust collecting barrel through a toggle effect, enabling quick and secure fitting of the barrel under a barrel cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the fastening ring is used to secure the dust collecting bag to the first air outlet, then the dust collecting bag can be fixed tightly, but the replacement process becomes time-consuming and complicated
Solution Approach 1:
The fastening ring is divided into a ring body and a buckle mechanism. The buckle mechanism includes a buckle body with a first linking member connected to the ring body, and a buckle seat with a second linking member. This segmentation allows the fastening ring to be operated as a lever system, reducing the effort and time required for tightening and loosening operations while maintaining secure fixation of the dust collecting bag.
2Reliability
If the dust collecting bag is tightly fitted to the first air outlet, then the sealing and fixation are improved, but the user needs sufficient space and effort for replacement
Solution Approach 1:
The buckle mechanism transforms the static fastening ring into a dynamic lever system. The first linking member and second linking member form a toggle mechanism that provides mechanical advantage. When the user pulls the free end of the buckle, the linking members rotate and amplify the force, enabling easy tightening and loosening operations with minimal effort and space requirement.
3Adaptability or versatility
If the fastening ring is loosened to disengage the dust collecting bag, then the bag can be replaced, but the process requires significant space and effort
Solution Approach 1:
The buckle mechanism acts as an intermediary between the user and the fastening ring. The linking members serve as mechanical mediators that translate the user's pulling action into rotational motion of the buckle body, which then controls the engagement and disengagement of the fastening ring. This intermediary mechanism simplifies the operation by providing a lever arm that reduces the direct force and space requirements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The buckle mechanism significantly enhances the efficiency of assembling and disassembling the dust collecting barrel, allowing for easy operation without bending, thereby improving user convenience and reducing the time required for maintenance.
Implementation Method 1
The fixing rod is sleeved with an elastic member. The elastic member is located between the barrel cover and the support member.

AI summary
A buckle mechanism of a dust collecting barrel of a bag-type dust collector includes a first retaining seat and a second retaining seat. Two sides of the first retaining seat are provided with two first linking members. Two sides of the second retaining seat are provided with two second linking members. The first linking members and the second linking members are connected through two connecting rods. An operating rod is provided between the second linking members. A support unit is provided between the first linking members. The support unit is fixed to a barrel cover. The second linking members are driven to swing by the operating rod and the first linking members are linked so that the barrel cover is moved up and down to quickly complete the assembly and disassembly of a dust collecting barrel.
