Detailed Description

The utility model is further illustrated, but is not limited to, the following examples.

As shown in fig. 1 to 4, the present utility model discloses a base assembly, comprising: the base 1, the base 1 is provided with a plug connector 11 and an elastic clamping connector 12; the chassis 2, be provided with spliced eye 21 and joint structure on the chassis 2, plug connector 11 with spliced eye 21 grafting cooperation, joint structure with elasticity joint spare 12 joint cooperation. When the base 1 and the chassis 2 are installed, the plug connector 11 and the elastic clamping piece 12 are directly adopted for matching installation, so that the problem that the cooling fan is unreliable due to complicated installation and insufficient installation caused by the need of using a locking bolt in the prior art is avoided, the installation operation is simplified, the reliable structure of the cooling fan is ensured, and the user experience is improved.

When the chassis 2 is installed, the chassis 2 is firstly inclined, the positions of the inserting holes 21 and the inserting pieces 11 correspond, then the chassis 2 is moved to enable the inserting pieces 11 to be gradually inserted into the inserting holes 21 until the inserting pieces 11 and the inserting holes 21 are installed in place, then the chassis 2 is rotated to enable the clamping structure to be gradually close to the elastic clamping piece 12, after the clamping structure is abutted with the elastic clamping piece 12, the chassis 2 is continuously rotated, and therefore the elastic clamping piece 12 is matched with the clamping structure in a clamping mode, and the installation of the chassis 2 is completed.

As shown in fig. 2 and 3, the base 1 is provided with a protruding structure 13, the plug connector 11 is disposed on a side wall of the protruding structure 13, the chassis 2 is provided with an avoidance groove 22 for accommodating the protruding structure 13, and the plug hole 21 is disposed at a groove bottom of the avoidance groove 22. The protruding structure 13 can enable the base 1 to be far away from the side surface of the chassis 2 to form grooves for installing other structures, and can also facilitate the arrangement of the plug connector 11 and the matching of the plug connector 11 and the plug hole 21. When the plug 11 and the plug hole 21 are installed in place, the protruding structure 13 also basically moves into the avoiding groove 22, and as the chassis 2 is gradually rotated, the protruding structure 13 is gradually installed into the avoiding groove 22 until the clamping structure is matched with the elastic clamping piece 12 in a clamping way, and the protruding structure 13 is also just completely located in the avoiding groove 22.

In order to facilitate the plug connector 11 to slide towards the plug hole 21, a guide groove is formed in the side wall of the avoidance groove 22, the guide groove is communicated with the plug hole 21, and the plug connector 11 can slide into the plug hole 21 along the guide groove.

Because chassis 2 direct contact ground, can outstanding chassis 2 when in order to avoid elasticity joint spare 12 and joint structure to cooperate, consequently, be provided with holding tank 14 on the protruding structure 13, elasticity joint spare 12 movably set up in the holding tank 14, the joint structure set up in dodge in the groove 22, and when protruding structure 13 set up in dodge in the groove 22, the joint structure is located in the holding tank 14. The elastic clamping piece 12 is arranged in the accommodating groove 14, so that the clamping structure can be matched with the elastic clamping piece 12 in the accommodating groove 14 in a clamping way, and the elastic clamping piece 12 is prevented from protruding out of the chassis 2.

Further, the clamping structure comprises a mounting protrusion 23, a clamping groove 24 is formed in the mounting protrusion 23, a clamping protrusion 15 is formed in the elastic clamping piece 12, and the clamping protrusion 15 can be matched with the clamping groove 24 in a clamping mode. The mounting protrusion 23 can extend into the accommodating groove 14, so that the matching position of the clamping protrusion 15 and the clamping groove 24 is in the accommodating groove 14, and the elastic clamping piece 12 is prevented from protruding out of the chassis 2.

When the elastic clamping piece 12 is matched with the clamping structure in a clamping way, the elastic clamping piece 12 is positioned on one side of the clamping structure, and the clamping protrusion 15 is positioned in the clamping groove 24.

For the convenience, the clamping bulge 15 breaks away from the clamping groove 24, an avoidance hole 25 is formed in the bottom of the avoidance groove 22, the avoidance hole 25 is communicated with the clamping groove 24, and the elastic clamping piece 12 located in the clamping groove 24 is exposed to the side surface of the chassis 2, away from the base 1, through the avoidance hole 25. The user can extrude the elastic clamping piece 12 in the clamping groove 24 from the side direction of the chassis 2 away from the base 1, so that the clamping protrusion 15 is separated from the clamping groove 24, and the chassis 2 and the base 1 are convenient to detach.

In order to improve the fixing reliability between the chassis 2 and the base 1, the number of the mounting protrusions 23 is plural, the elastic clamping members 12 are in one-to-one correspondence with the mounting protrusions 23, and the openings of at least two clamping grooves 24 are oriented at an included angle. That is, the elastic clamping piece 12 and the mounting protrusion 23 are matched to generate extrusion force in at least two directions, so that the chassis 2 can be limited in at least two directions, and the fixing reliability of the chassis 2 and the base 1 is improved.

As shown in fig. 2, two mounting protrusions 23 are provided, openings of the two clamping grooves 24 are opposite, at this time, the two elastic clamping pieces 12 are respectively clamped with the corresponding clamping grooves 24, two extrusion forces with equal magnitudes and opposite directions are formed, and resultant force of the two extrusion forces is zero, so that reliable fixing of the chassis 2 and the base 1 is realized.

In order to further improve the fixing reliability of the chassis 2 and the base 1, the base assembly further comprises a bolt 3, a threaded hole 16 is formed in the base 1, a through hole 26 is formed in the chassis 2, and the bolt 3 is matched with the threaded hole 16 to fix the chassis 2 on the base 1. The user can directly rotate the bolt 3 without tools such as a screwdriver, so that the chassis 2 and the base 1 can be locked.

The chassis 2 is provided with a counterweight structure.

Casters are arranged on the chassis 2.
