Description

Dust bucket fastening device

technical field

The utility model relates to a dust suction bucket, in particular to a dust suction bucket fastening device.

Background technique

In order for workers to have a better working environment, at present, many sewing machines used in factories are equipped with dust collection devices, and plastic buckets are used in the dust collection devices to store thread ends, cloth scraps and dust. The dust collection mechanism of the dust collection device is installed on a bucket cover, so the bucket cover is fixed on the sewing machine. When the garbage is full, the garbage can be removed by removing the bucket body. In order to facilitate installation and take out of the bucket body, Usually, some clamping blocks are set on the outer wall of the barrel and some restricting blocks are set on the bottom of the lid. When installing, just rotate the barrel so that the clamping blocks are screwed into the bottom of the restricting block to engage with it, and the barrel can be fixed. on the lid. However, there are defects in the above-mentioned structure, that is, when the barrel body is installed, the barrel body and the barrel cover are often out of alignment, so that the clamping block cannot be screwed into the bottom of the limiting block when rotating, so the operation is inconvenient and time-consuming, thereby reducing the work. Efficiency, also inconvenient for the assembly of vacuum device and staving simultaneously.

Therefore, in view of the above defects, the designer designed a structure with an inclined surface on the clamping block, through the guidance of the inclined surface, the barrel body and the lid can be aligned smoothly, and the clamping block can be easily screwed into the bottom of the restricting block And engage with it.

Contents of the invention

In order to overcome the deficiencies of the prior art, the utility model provides an easy-to-use buckling device for dust collection barrels.

The technical scheme that the utility model solves its technical problem adopts is:

The buckling device of the vacuum bucket is characterized in that it includes a number of clamping blocks arranged on the outer wall of the barrel and a number of limiting blocks arranged on the bottom surface of the bucket cover, the limiting blocks are fixed on the bottom surface of the bucket cover through connecting fasteners, and the limiting The block can be locked with the clamping block through the rotation of the barrel lid, and the clamping block is provided with a first guiding slope.

The limiting block includes a main body and positioning parts and tongues respectively arranged on both sides of the main body. The edge of the bung is provided with a number of protruding parts, and the protruding parts are provided with positioning grooves. In the groove, the tongue protrudes from the edge of the bucket lid, and the main body is fixed on the bottom surface of the bucket lid through the connecting fastener, and the clamping block is locked with the tongue.

A limiting part is provided on the locking block, and the limiting block can be engaged with the limiting part.

The tongue is provided with a second guiding slope.

The beneficial effects of the utility model are: the buckling device of the vacuum bucket includes a plurality of clamping blocks arranged on the outer wall of the barrel and a plurality of restricting blocks arranged on the bottom surface of the barrel cover. When the barrel body and the barrel cover are closed, the restricting blocks can Through the rotation of the bung, it is rotated to the bottom of the clamping block and locked with the clamping block. When the bung is rotated in the opposite direction, the restricting block can be separated from the clamping block, thereby uncovering the bung. The above structure can be used conveniently and quickly. The bucket body and the bucket cover are closed or separated, so that it is convenient to clean up the garbage in the bucket, saving working time and improving work efficiency, and the clamping block has a slope structure, and the bucket body and the bucket cover can be smoothly aligned through the guidance of the slope In the center, and the clamping block is easily screwed into the bottom of the limiting block to engage with it.

Detailed ways

Referring to Fig. 1 to Fig. 3, the utility model discloses a buckling device for a vacuum bucket, which includes a plurality of clamping blocks 1 arranged on the outer wall of the barrel body 2 and a plurality of restricting blocks 4 arranged on the bottom surface of the barrel cover 3, specifically in this In the example, the clamping block 1 is provided with six pieces, which are evenly distributed on the outer wall of the barrel body 2, and three restricting blocks 4 are also uniformly distributed on the bottom surface of the barrel cover 3, and the number of the clamping blocks 1 is large so that the rotation of the restricting block 4 is relatively small. It is locked with the clamping block 1 at an angle of 1, and the limiting block 4 is fixed on the bottom surface of the bucket cover 3 through connecting fasteners. Through the rotation of the barrel cover 3, it is locked with the locking block 1.

As shown in the figure, the restricting block 4 includes a main body 5 and a positioning portion 6 and a tongue 7 respectively arranged on both sides of the main body 5. The bung 3 is provided with a plurality of protruding parts 8, and the protruding parts 8 are connected with the barrel. The cover 3 is integrally formed, and the protruding part 8 is provided with a positioning groove 9, and the positioning part 6 is located in the positioning groove 9, so that its relative position can be fixed when the limiting block 4 is installed, and the tongue part 7 protrudes from the edge of the barrel cover 3 , and the main body part 5 is fixed on the bottom surface of the bucket cover 3 through the connecting fasteners, and the clamping block 1 is locked with the tongue part 7 . Further, the tongue 7 is provided with a second guiding inclined surface, which can guide the barrel lid 3 to engage with the barrel body 2 .

As shown in the figure, the clamping block 1 is provided with a limiter 10, and the limiter 4 can be locked with the limiter 10, so as to prevent the limiter 4 from turning over and clamping due to excessive rotation when the barrel lid 3 rotates. The locked position of block 1 makes it difficult to engage. Further, the clamping block 1 is provided with a first guide slope 11, through the guidance of the first guide slope 11, avoiding the deformation of the barrel lid 3 or other reasons, the restricting block 4 is pushed to death by the clamping block 1 when it rotates, and cannot Rotate to below the clamping block 1.
