DETAILED DESCRIPTION

[0033] Refer to the accompanying drawings Figures 1 to 9 The utility model discloses a spring floor cleaner makes further detailed instructions.

[0034] A spring floor cleaner, comprising a base 1 mounted on the ground and a locking assembly 2 mounted on the door panel, the base 1 is provided with a base upper cover 13; the base 1 is provided with a locking groove 11 matched with the locking assembly 2, the locking assembly 2 comprises a mounting seat 21 provided with a mounting cavity 211 and a locking column 22 and a locking spring 23 and an adjusting screw 24 mounted in the mounting cavity 211 from bottom to top, wherein the base 1 and the locking column 22 are both made of PA66 material;

[0035] The inner side wall of the upper end of the mounting cavity 211 is provided with an internal thread 2111, and the adjusting screw 24 is threadedly matched with the internal thread 2111;

[0036] The upper end of the locking spring 23 abuts against the adjusting screw 24, and the lower end thereof abuts against the upper end of the locking column 22;

[0037] When the door panel is opened to the corresponding position of the floor cleaner base 1, the locking column 22 slides into the locking groove 11 from the base 1 and is inserted into the locking groove 11 under the elastic force of the locking spring 23, and the locking column 22 and the locking groove 11 are matched to lock the door panel on the device to be positioned, realizing the positioning function of the floor cleaner on the door panel; when the door is closed inward, the locking column 22 is extruded upward by the side wall of the locking groove 11, the locking column 22 is separated from the locking groove 11, and the locking of the door panel is released; when the positioning force of the floor cleaner on the door panel needs to be adjusted, only the adjusting screw 24 needs to be twisted; the adjusting screw 24 is twisted upward, the compression force of the adjusting screw 24 and the locking column 22 on the locking spring 23 is reduced to reduce the elastic force of the locking spring 23, so that the locking force of the locking column 22 on the door panel is reduced, facilitating the door closing operation of people; the adjusting screw 24 is twisted downward, the compression force of the adjusting screw 24 and the locking column 22 on the locking spring 23 is increased to increase the elastic force of the locking spring 23, so that the locking force of the locking column 22 on the door panel is increased; the locking force of the floor cleaner on the door panel is adjustable, and the applicability of the product is improved.

[0038] The first guide surface 12 is arranged at the entrance of the base 1, and the lower end of the locking column 22 slides into the locking slot 11 along the first guide surface 12; the second guide surface 111 is arranged at the exit of the locking slot 11, and the lower end of the locking column 22 slides into the locking slot 11 along the second guide surface 111; the inclination angle of the second guide surface 111 is greater than that of the first guide surface 12.

[0039] During the process that the locking column 22 enters the locking slot 11 from the first guide surface 12, the first guide surface 12 compresses the locking column 22 upward, and when the locking column 22 moves to the position of the locking slot 11, the locking spring 23 drives the locking column 22 to fall into the locking slot 11 to lock the door plate.

[0040] When closing the door, only the door plate needs to be pushed, the locking column 22 slides out of the locking slot 11 along the second guide surface 111, and the locking column 22 is compressed upward, so that the locking column 22 moves upward and separates from the locking slot 11.

[0041] The end surface of the locking slot 11 is provided with a buffer pad 3, and the buffer pad 3 is made of TPU material; the buffer pad 3 reduces the impact sound of the locking column 22 and the base 1, so as to reduce the noise.

[0042] The mounting seat 21 is detachably mounted with a shell 25, both sides of the mounting seat 21 are provided with buckle grooves 212, the shell 25 is provided with buckles 251 matched with the buckle grooves 212, the buckles 251 and the corresponding buckle grooves 212 are matched to fix the shell 25 on the mounting seat 21; the upper end of the mounting seat 21 is provided with two upper clamping grooves 213, and the lower end of the mounting seat 21 is provided with lower clamping blocks 214 on both sides; the upper end of the shell 25 is provided with two upper clamping blocks 252, and the lower end of the shell 25 is provided with lower clamping blocks 214 on both sides; the upper clamping blocks 252 and the upper clamping grooves 213 are matched one by one, and the lower clamping blocks 253 and the lower clamping blocks 214 are matched one by one; through the buckles 251 and the buckle grooves 212, the upper clamping blocks 252 and the upper clamping grooves 213, and the lower clamping blocks 214 and the lower clamping grooves 253, the shell 25 is fixed firmly on the outside of the mounting seat 21, so as to avoid external dust from entering the locking assembly 2, and improve the appearance of the suction.

[0043] The two sides of the mounting seat 21 are provided with waist-shaped mounting holes 215, and the waist-shaped mounting holes 215 are arranged in the vertical direction to realize the vertical adjustment of the mounting seat 21; the installation position of the locking assembly 2 is adjusted conveniently.

[0044] The above merely is preferred implementation manner of the present application, the protection scope of the present application is not only limited to the above examples, and belongs to the technical scheme under the idea of the present application all belongs to the protection scope of the present application. It should be pointed out that, for ordinary skilled person in the art, under the premise of not departing from the principle of the present application, some improvements and decorations, these improvements and decorations should also be considered as the protection scope of the present application.
