Description

Technical Field

[0001] This utility model relates to the field of foot switch technology, specifically to a self-locking protective cover foot switch structure. Background Technology

[0002] A foot switch is a switch that controls the on / off state of a circuit by stepping on it. It is used in control circuits where the hands cannot reach, thus replacing the need for hand operation. Foot switches are widely used in medical devices, stamping equipment, welding equipment, textile equipment, and printing machinery.

[0003] The existing foot switch structure still has shortcomings: the structural design is unreasonable, the protective cover of the existing foot switch cannot be locked, it is easy to be misoperated, and its practicality is poor. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a self-locking protective cover foot switch structure with reasonable structural design, self-locking protective cover, low risk of misoperation, convenient use and good practicality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-locking protective cover foot switch structure, including a base, a foot switch provided at the upper end of the base, a protective cover provided above the foot switch, and the rear end of the protective cover being hinged to the rear end of the base, characterized in that: a rotating shaft is provided between the rear end of the protective cover and the rear end of the base, and a torsion spring is sleeved on the rotating shaft, the rear end of the protective cover and the rear end of the base are hinged through the rotating shaft, and the protective cover is reset by the torsion spring;

[0006] A self-locking mechanism is provided between the front end of the upper end of the base and the front end of the lower end of the protective cover. The protective cover can be locked or released by stepping on it.

[0007] The present invention is further configured as follows: the self-locking mechanism includes a lock cylinder, a movable plate, a self-locking plate, a pin, a spring, and a ball bearing; the upper front end of the base is provided with a base hole aligned with the lock cylinder position; a connecting plate is integrally provided at one end of the lock cylinder; the connecting plate is connected and fixed to the lower front end of the protective cover by screws; a lock cylinder groove is provided inside the lock cylinder; the spring and the ball bearing are both installed in the lock cylinder groove, with the ball bearing located at the outer end of the spring; the self-locking plate is installed at the outer port position of the lock cylinder groove, and the self-locking plate is hinged by a pin; the movable plate is sleeved on the lock cylinder.

[0008] When the protective cover is stepped on, the movable plate and the base are displaced. The movable plate pushes the self-locking plate to rotate and compress the spring at the inner end of the ball bearing. When the protective cover is released, the self-locking plate rotates and locks against the inner wall of the base hole. When the protective cover is stepped on again, the movable plate moves and pushes the self-locking plate to flip and release the self-lock, thereby releasing the protective cover.

[0009] The present invention is further configured such that the free opening angle of the protective cover is 70°, and several anti-slip ribs are integrally provided on the upper surface of the protective cover.

[0010] The present invention is further configured such that: a plurality of foot pads are provided on the lower end surface of the base, and the upper end surface of the foot pads is integrally formed with the lower end surface of the base or is fixed by adhesive.

[0011] The present invention is further configured such that a lock is provided at the rear end of the base.

[0012] The beneficial effects of this utility model are: compared with the prior art, the structure of this utility model is reasonable, the protective cover and the base can be adapted to a variety of different foot switches, the protective cover is rotated by the pivot and the torsion spring is reset, and the protective cover can be locked and released by stepping on it multiple times during use. When the user does not use it, the protective cover can be locked to avoid accidental operation.

[0013] The protective cover can be opened at a free angle of 70° to accommodate the space required by various types of shoes.

[0014] When the protective cover is stepped on, the movable plate and the base are displaced. The movable plate pushes the self-locking plate to rotate, compressing the spring at the inner end of the ball bearing. When the protective cover is released, the self-locking plate rotates and locks against the inner wall of the base hole. When the protective cover is stepped on again, the movable plate moves, pushing the self-locking plate to flip and release the self-lock, thus releasing the protective cover. The protective cover is self-locking, not prone to accidental operation, easy to use, and highly practical.
