[0026] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0027] Please refer to Figures 1 to 3 The dust collector test docking device shown in an embodiment of the application is arranged on a test box of a dust collector test device, and is used to dock with an air inlet pipe (not shown) of a dust collector 200. The dust collector 200 in this embodiment is a handheld dust collector. An end of a main cyclone separation unit of the dust collector 200 forms a dust cup portion. The main cyclone separation unit has a cup body 202 and an end cover 203 pivotally connected to the cup body 202. After the end cover 203 is opened, dirt in the dust cup can be poured out. The end cover 203 is fixed with the air inlet pipe. The end cover 203 is provided with a sealing member (not numbered) and a buckle structure. The buckle structure has a buckle slot 204. When the air inlet pipe and the pipe body are docked, a clamping hook on the pipe body is clamped in the buckle slot to achieve locking between the pipe body and the air inlet pipe. At this time, the sealing member is clamped between the pipe body and the end cover 203 to achieve a sealing effect.

[0028] The dust collector test docking device includes a fixing plate 10 arranged on the test box, a docking cylinder 20 fixed on the fixing plate 10, and a locking assembly arranged above the docking cylinder 20. The docking cylinder 20 is provided with a plug-in cavity 21 for inserting the air inlet pipe. The locking assembly includes a clamping piece 31 clamped in the buckle slot 204 of the dust collector 200 and an actuating piece driving the clamping piece 31 to rotate to be locked in the buckle slot 204. The dust collector test docking device uses the buckle slot 204 of the dust collector 200 itself. The clamping piece of the locking assembly is matched with the buckle slot 204 to achieve locking between the dust collector 200 and the docking cylinder 20. Since the clamping piece 31 is rotated to be locked in the buckle slot 204 by the actuating piece, the rotation direction of the clamping piece 31 is not the axial movement direction. Compared with the prior art, the positioning of the dust collector 200 is more stable, which can avoid affecting the air tightness between the air inlet pipe and the test box due to axial movement, and helps to improve the accuracy of the test results.

[0029] The docking cylinder 20 has a wall body 22 surrounding the plug-in cavity 21. An end of the wall body 22 forms a profiled surface 23 used to dock with a sealing ring on the dust collector 200. The profiled surface 23 is a hard structure. The profiled surface 23 and the sealing ring are matched to improve the air tightness.

[0030] In the embodiment, the locking assembly further comprises a transmission assembly which transmits the force of the actuating member to the buckle 31. The transmission assembly comprises a long strip-shaped plate body 33, the abutting cylinder 20 is formed with a protrusion 24, the middle part of the long strip-shaped plate body 33 is downwardly protruded to form a reverse boss 331, and the reverse boss 331 is installed on the protrusion 24 through a pin shaft. The buckle 31 is installed on one end of the long strip-shaped plate body 33, and the actuating member applies force on the other end of the long strip-shaped plate body 33. In the embodiment, the buckle 31 is a plastic member, and the long strip-shaped plate body 33 is an aluminum plate. The buckle 31 is fixed on the aluminum plate through a fastener. The strength of the long strip-shaped plate body 33 is improved through the aluminum plate, and the buckle 31 is set as a plastic member to avoid abrasion to the handheld vacuum cleaner 200. In other embodiments, the long strip-shaped plate body 33 and the buckle 31 can be formed as one part through aluminum injection molding, and then a resilient material is arranged on the buckle 31 to avoid abrasion to the handheld vacuum cleaner 200.

[0031] The long strip-shaped plate body 33 is similar to a seesaw. In order to move smoothly when moving up and down on both ends, the transmission assembly further comprises a guide rod which is vertically arranged below the long strip-shaped plate body 33, and the abutting cylinder 20 is formed with a guide groove into which the guide rod is inserted. Specifically, the guide rod comprises a first guide rod 341 and a second guide rod 342 which are respectively located on both sides of the pin shaft. The first guide rod 341 is arranged away from the buckle 31 compared with the second guide rod 342. The guide groove comprises a first guide groove 251 and a second guide groove 252 which are arranged corresponding to the first guide rod 341 and the second guide rod 342. Of course, in order to achieve the above purpose, in other embodiments, the guide groove can be arranged on the long strip-shaped plate body 33, that is, a guide hole is formed on the long strip-shaped plate body 33, and the guide rod is arranged on the abutting cylinder 20. In the embodiment, the actuating member is a resilient member (not shown) arranged in the first guide groove 251, specifically a spring. The resilient member is located below the first guide rod 341. The rotation of the buckle 31 is realized through the spring to realize the locking between the buckle 31 and the buckle groove, so as to reduce the control points of the whole test device, thereby the calculation amount of the control system of the test device can be reduced.

[0032] In the embodiment, in order to realize the unlocking between the buckle 31 and the buckle groove 204, the vacuum cleaner test docking device further comprises a pneumatic cylinder 32 which applies downward force to one end of the long strip-shaped plate body close to the actuating member. The pneumatic cylinder 32 has a cylinder body (not numbered) fixed on the fixed plate 10 through a mounting plate and a plunger (not numbered) installed in the cylinder body. The plunger has a free end located outside the cylinder body, and a roller 35 is installed on the free end. The roller 35 is located above the long strip-shaped plate body 33, so that the roller 35 applies the force of the pneumatic cylinder 32 to the long strip-shaped plate body 33.

[0033] When the air inlet pipe is inserted into the docking tube 20, the cylinder 32 drives the roller 35 to apply force to the long strip plate 33, so that the long strip plate 33 is kept in the Figure 3 As shown in the position, the spring is in a tensioned state, and its restoring force is less than the force exerted by the cylinder 32 on the long plate 33; when the air inlet pipe is inserted into the docking tube 20 and in place, the cylinder 32 is started, causing the roller 35 to move upward, and the force exerted by the roller 35 on the long plate 33 is cancelled. At this time, the restoring force of the spring causes the long plate 33 to rotate until the buckle 31 is snapped into the buckle groove 204, thereby achieving locking. Figure 2 Status shown.

[0034] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
