[0002] At present, most of the hanging basket limit switches on the market are fixed by bolts on the iron sheet on the back of the safety lock. However, due to the long-term exposure of the limit switch to the outside and the single fixing form, it is easy to cause the limit switch to fail, the electric bell cannot alarm, the circuit cannot be cut off and other problems, thus posing a great safety hazard. Utility Model Content

[0003] The utility model aims to provide a U-shaped square steel protection device for a hanging basket limit switch to solve the problems raised in the above-mentioned background technology.

[0005] In a preferred embodiment, bending portions are arranged opposite to each other on the two edges of the opening side of the U-shaped square steel, and the bending portions and the back and two side surfaces of the U-shaped square steel form a three-sided enclosure structure with an opening. The limit switch is located in the three-sided enclosure structure, and the cross-section of the limit switch is a rectangle. The distance between the two bending portions is smaller than the length of the cross-section of the limit switch.

[0006] In a preferred embodiment, two first bolt holes are spaced apart at the lower portion of the back side of the U-shaped square steel, and bolt assemblies are connected in the first bolt holes.

[0007] In a preferred embodiment, the width of the U-shaped square steel is 50 mm, and the width of each bending portion is 10 mm.

[0008] In a preferred embodiment, a second bolt hole is opened on one side of the U-shaped square steel, a bracket bolt is connected to the second bolt hole, and the length of the bracket bolt extending from the inner wall of the side of the U-shaped square steel is less than half the cross-sectional length of the limit switch.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows: the traditional practice uses the form of fixing the limit switch on the back iron sheet of the safety lock. Since there is only a single iron sheet on the back, it is impossible to effectively protect the limit switch, and the rigidity is insufficient, which easily causes the limit switch to tilt, resulting in limit switch failure. The U-shaped square steel protection device of the utility model can wrap the limit switch of the hanging basket safety lock on three sides to form a protection structure to ensure the fixing effect of the limit switch. The opening on one side can be used for routine inspection and maintenance of the limit switch, and there is no risk of tilting after installation. The device can be mass-produced in the factory, is easy to install, safe and reliable, and can be used in a turnover manner. At the same time, the hanging basket limit switch is effectively protected. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The technical solutions in the embodiments of the utility model are described clearly and completely below. The embodiments of the utility model and all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example 1

[0018] like Figures 1 to 4As shown, the U-shaped square steel protection device of the hanging basket limit switch of the preferred embodiment of the utility model is fixed on one side of the hanging basket safety lock, including: U-shaped square steel 1, 11-bending part, limit switch 2, bracket bolt 3, bolt assembly 4 and wire 5, wherein the U-shaped square steel 1 is arranged in the vertical direction, the front side of the U-shaped square steel 1 is the open side, and the back side of the U-shaped square steel 1 is fixed to the hanging basket safety lock through the bolt assembly 4. The limit switch 2 is inserted into the U-shaped groove of the U-shaped square steel 1 from top to bottom, and the bracket bolt 3 is inserted from the outside to the inside on one side of the U-shaped square steel 1, and extends to the bottom of the limit switch 2, and abuts against the bottom of the limit switch 2, so that the bracket bolt 3 serves as a support to support the limit switch 2. The wire 5 is arranged in the U-shaped groove and is connected to the line of the limit switch 2. By using the U-shaped square steel to wrap the limit switch on three sides, the probability of the limit switch tilting after touching the limit block multiple times is effectively reduced, the service life of the limit switch is improved, and the safety of the hanging basket construction is greatly improved.
