Description

Technical Field

[0001] The utility model relates to the technical field of bathroom equipment, in particular to a button structure and a shower faucet. Background Art

[0002] At present, faucet button valve cores are widely used in shower faucets. Most of the button structures on the market now use a combination of valve core, connection seat, screws and button cover for installation, that is, the connection seat is directly locked on the button valve core with screws, and the button cover is fastened to the connection seat for connection and fixation. After connection, the valve core and the button are relatively fixed. This method of switching action is linear motion. In production, due to the accumulation of size or position tolerances and guiding factors, the edge of the button cover is prone to get stuck with the shell, resulting in the valve core not rebounding, resulting in a poor experience. In addition, the above installation method has high requirements on the processing accuracy and position of the part size. At the same time, the aperture of the shell and the button is often enlarged during design to increase the matching clearance to reduce key jamming. This method requires sacrificing the appearance of the product. Utility Model Content

[0028] Referring to Figures 1-5 , a key structure includes a key cap 100, a fixing sleeve 200, a key valve core 300 and a housing 400. The fixing sleeve 200 is made of plastic. A key hole 410 is formed on the housing 400. The fixing sleeve 200 is in a ring-shaped structure. The fixing sleeve 200 is coaxially arranged with the key hole 410. The fixing sleeve 200 is fixedly connected to the housing 400. The key cap 100 passes through the key hole 410 and the fixing sleeve 200. The key cap 100 is slidably connected to the fixing sleeve 200 along the axial direction. A first magnetic attraction member is provided on the pressing portion of the key valve core 300, and a second magnetic attraction member is provided on the key cap 100. The first magnetic attraction member and the second magnetic attraction member are attracted to each other.

[0029] The key valve core 300 of the present utility model is magnetically connected to the key cap 100, so that the key valve core 300 and the key cap 100 are not completely fixed, and the key cap 100 and the fixing sleeve 200 remain in a coaxial state. Even if the key valve core 300 and the key cap 100 are not coaxial due to manufacturing dimensions or installation reasons, during normal use, when the key cap 100 is operated to press the key valve core 300 to open and close, the key cap 100 will not get stuck with the housing 400. The present utility model reduces the influence of dimensional deviation on key jamming, has better operability, reduces the accumulation of dimension chains, reduces the requirements for the dimensions or position tolerances of related parts, is easier to control dimensions, and there is no need to increase the clearance between the key hole 410 and the key cap 100, making the clearance of the key uniform and beautiful.

[0030] In some embodiments of the present utility model, the fixing sleeve 200 is located behind the key hole 410. Positioning plates 420 for fixing the fixing sleeve 200 are provided on both sides of the key hole 410. The positioning plates 420 are fixed on the housing 400. Limiting grooves 421 are formed on the positioning plates 420. First positioning ribs 210 are provided on the outer peripheral wall of the fixing sleeve 200. The fixing sleeve 200 is installed on the positioning plates 420 through the cooperation of the first positioning ribs 210 and the limiting grooves 421.

[0031] In some embodiments of the present utility model, the limiting groove 421 is vertically arranged, and the lower part of the limiting groove 421 extends downward until it penetrates the bottom of the positioning plate 420 so that the limiting groove 421 has an opening facing downward, or the upper part of the limiting groove 421 extends upward until it penetrates the top of the positioning plate 420 so that the limiting groove 421 has an opening facing upward. When the opening of the limiting groove 421 faces downward, the fixing sleeve 200 is inserted into the positioning plate 420 from bottom to top; when the opening of the limiting groove 421 faces upward, the fixing sleeve 200 is inserted into the positioning plate 420 from top to bottom. The limiting groove 421 is used to limit the front-back movement of the fixing sleeve 200.

[0032] In some embodiments of the present utility model, second positioning ribs 220 are provided on the outer peripheral wall of the fixing sleeve 200, and the second positioning ribs 220 can abut against the side surface of the positioning plate 420. The second positioning ribs 220 are located on the left and right sides of the fixing sleeve 200 and respectively abut against the positioning plates 420 on the left and right sides, restricting the left-right movement of the fixing sleeve 200.

[0033] In some embodiments of the present utility model, a positioning hook 230 is provided on the upper or lower part of the fixing sleeve 200, a groove 430 is provided on the outer shell 400 and the groove 430 is located above or below the key hole 410. After the fixing sleeve 200 is installed on the positioning plate 420, the positioning hook 230 is clamped in the groove 430. The cooperation of the positioning hook 230 and the groove 430 restricts the up-down movement of the fixing sleeve 200.

[0034] In some embodiments of the present utility model, a sliding groove 240 is provided on the inner peripheral wall of the fixing sleeve 200, the sliding groove 240 is arranged along the axial direction of the fixing sleeve 200, a protrusion 110 is provided on the outer peripheral wall of the key cap 100, and the protrusion 110 is embedded in the sliding groove 240 and can move along the sliding groove 240. The cooperation of the sliding groove 240 and the protrusion 110 realizes the sliding connection between the fixing sleeve 200 and the key cap 100, ensuring that the key cap 100 will not rotate and can only move axially along the sliding groove 240.

[0035] In some embodiments of the present utility model, there are two or more protrusions 110 and they are distributed circumferentially along the key cap 100. The shapes or sizes of at least two protrusions 110 are different. The number of sliding grooves 240 is the same as the number of protrusions 110, and the sliding grooves 240 and the protrusions 110 are in pairwise cooperation. When marks need to be printed on the surface of the key cap 100, the protrusions 110 with different shapes or sizes can ensure that the key cap 100 is installed in the same direction, facilitating the workers not to make mistakes during assembly.

[0036] In some embodiments of the present utility model, an elastically deformable snap 250 is provided on the fixing sleeve 200. During the process of the button cover 100 passing through the fixing sleeve 200, the snap 250 is forced to abut against the outer peripheral wall of the button cover 100 and elastically expand until the deformation of the snap 250 is restored after the button cover 100 reaches the assembly position. The snap 250 is located at the rear end of the fixing sleeve 200. During installation, the button cover 100 is inserted into the fixing sleeve 200 from the back of the fixing sleeve 200, and a thrust is applied to deform and expand the snap 250. When the button cover 100 is installed inside the fixing sleeve 200, the snap 250 is disengaged from the button cover 100, and the snap 250 returns to its original state, so that the button cover 100 is retained inside the fixing sleeve 200 without falling off.

[0037] In some embodiments of the present utility model, the first magnetic member is a screw 500, and the screw 500 is threadedly connected to the pressing portion of the button valve core 300. The second magnetic member is a magnet 600. The magnet 600 is fixed inside the button cover 100 by means including but not limited to injection molding, snap connection, etc., so that the magnet 600 and the button cover 100 form a fixed assembly. Since the magnet 600 is provided on the button cover 100, the screw 500 will generate a mutual attraction with the button cover 100, realizing the connection between the button cover 100 and the button valve core 300.

[0038] A shower faucet includes the above button structure.

[0039] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model.
