Description

Technical Field

[0001] The utility model relates to the technical field of button switches, in particular to a button switch. Background Art

[0002] The button on a push button switch can be designed to be both depressible and rotatable. This design allows the user to control the switch state by rotating the button, increasing operational flexibility and functionality. However, this design also results in a compact structure within the push button switch and a complex internal mechanical structure. Therefore, when adding a waterproof structure, the internal dimensions of the housing are often limited, resulting in a simple waterproof structure. After the button is rotated and pressed multiple times, the waterproof structure will be worn, resulting in a deterioration of the waterproof effect. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] See also Figures 1-6 The utility model provides a technical solution: a push button switch, comprising a housing 1, a rotary button 2 is provided on the top of the housing 1, and a waterproof mechanism 4 is provided between the housing 1 and the rotary button 2;

[0023] The waterproof mechanism 4 includes a connecting sleeve 1 401, a connecting sleeve 2 404, and a rotating seat 406. The connecting sleeve 1 401 is fixedly mounted on the bottom of the rotary button 2, and the rotating seat 406 is fixedly mounted on the outer wall of the shell 1. The inner wall of the connecting sleeve 1 401 is fixedly mounted with a mounting ring 402, and the bottom of the mounting ring 402 is fixedly mounted with a sealing ring 1 403. The top of the connecting sleeve 2 404 extends into the connecting sleeve 1 401, and the connecting sleeve 2 404 is rotatably sleeved on the shell 1. The top of the connecting sleeve 2 404 is pressed on the sealing ring 1 403. The connecting sleeve 1 401 and the connecting sleeve 2 404 are fixedly connected by connecting bolts 407. The bottom of the connecting sleeve 2 404 is fixedly mounted with a corrugated sleeve 405, and the corrugated sleeve 405 is sleeved on the shell 1. The bottom end of the corrugated sleeve 405 is fixedly connected to the movable end of the rotating seat 406. 5. The rotating seat 406 covers the joint between the shell 1 and the rotary button 2 to achieve waterproofing of the joint between the shell 1 and the rotary button 2. The connecting sleeve 1 401 and the connecting sleeve 2 404 are fixedly connected by the connecting bolt 407, so that the connecting sleeve 1 401 and the connecting sleeve 2 404 are detachable. At the same time, a mounting ring 402 is provided for mounting a sealing ring 1 403 to prevent water from entering the inner side of the connecting sleeve 1 401 from the connection between the connecting sleeve 1 401 and the connecting sleeve 2 404. The connecting sleeve 2 404 and the rotating seat 406 are connected by a corrugated sleeve 405, so that when the rotary button 2 is pressed, the connecting sleeve 1 401 and the connecting sleeve 2 404 move downward, thereby squeezing the corrugated sleeve 405. The corrugated sleeve 405 and the shell 1 are connected by the rotating seat 406, so that when the rotary button 2 is rotated, the corrugated sleeve 405 can rotate relative to the shell 1, thereby avoiding the problem of the corrugated sleeve 405 being excessively twisted and worn.

[0024] The rotating seat 406 includes a fixing ring 4061, which is fixedly mounted on the housing 1. A waterproof bearing 4062 is fixedly mounted on the outer wall of the fixing ring 4061. A connecting sleeve 3 4063 is fixedly mounted on the outer side of the waterproof bearing 4062. The connecting sleeve 3 4063 is the movable end of the rotating seat 406. The top of the connecting sleeve 3 4063 is fixedly connected to the bottom of the corrugated sleeve 405. The fixing ring 4061 is provided for mounting the waterproof bearing 4062. The fixing ring 4061 and the connecting sleeve 3 4063 are connected by the waterproof bearing 4062, so that the connecting sleeve 3 4063 can rotate relative to the housing 1, thereby allowing the corrugated sleeve 405 to rotate relative to the housing 1.

[0025] The outer wall of the housing 1 is fixedly mounted with an anti-slip cover 3, which makes it easy to hold the housing 1. The top of the rotary button 2 is provided with an identification arrow 8 for identifying the rotation position of the rotary button 2.

[0026] A connecting post 5 is fixedly mounted on the bottom of the second connecting sleeve 404. The bottom end of the connecting post 5 movably passes through the top of the third connecting sleeve 4063. A locking ring 6 is fixedly mounted on the outer wall of the connecting post 5. The locking ring 6 is located below the third connecting sleeve 4063. The second connecting sleeve 404 and the third connecting sleeve 4063 are connected by the connecting post 5, so that the second connecting sleeve 404 can move up and down relative to the third connecting sleeve 4063. However, when the second connecting sleeve 404 is driven to rotate, the third connecting sleeve 4063 can be driven to rotate synchronously. That is, the torsional force is not transmitted through the corrugated sleeve 405, which can more effectively avoid the problem of wear of the corrugated sleeve 405 due to torsion.

[0027] A groove is formed on the outer wall of the second connecting sleeve 404 on one side facing the first connecting sleeve 401. A second sealing ring 9 is fixedly installed inside the groove, which cooperates with the first sealing ring 403 to form a double layer of waterproofing, thereby improving the waterproofing effect of the joint between the first connecting sleeve 401 and the second connecting sleeve 404.

[0028] The top and bottom ends of the connecting bolt 407 are both threaded with nuts, and the outer wall of the nut is fixed with a protective cap 7. The end of the protective cap 7 is provided with a hexagonal groove. The protective cap 7 is provided to protect the connecting bolt 407, reduce the probability of the connecting bolt 407 being eroded by rainwater, and reduce the degree of corrosion of the connecting bolt 407.

[0029] Working principle: When in use, insert the top end of the connecting sleeve 2 404 into the connecting sleeve 1 401 until the top end of the connecting sleeve 2 404 is pressed on the sealing ring 1 403, and then use the connecting bolt 407 to fix the connecting sleeve 1 401 and the connecting sleeve 2 404 to complete the waterproofing of the joint between the shell 1 and the rotating button 2. When pressing the rotating button 2, the rotating button 2 drives the connecting sleeve 1 401 to move downward, and then drives the connecting sleeve 2 404 to move downward, so that the corrugated sleeve 405 is compressed. When the rotating button 2 is rotated, the rotating button 2 drives the connecting sleeve 1 401 to rotate, and then drives the connecting sleeve 2 404 to rotate. The rotation of the connecting sleeve 2 404 drives the connecting column 5 to rotate, and then drives the connecting sleeve 3 4063 to rotate synchronously, ensuring that the corrugated sleeve 405 will not twist.

[0030] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.
