Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: spring buckle for high-speed railway, including base 1 and bar spring 2, the upper end middle part welding of base 1 has slide 3, the inside slip of slide 3 has gag lever post 4, the upper end welding of gag lever post 4 has mount pad 5, the upper end right part welding of base 1 has detain seat 9, the upper portion of detaining seat 9 is rotated and is connected with fastener 10, bar spring 2 is M type structure, gag lever post 4's diameter is less than the middle part interval that is M type bar spring 2, the bottom of mount pad 5 is seted up flutedly, and the rubber pad is installed to the bottom of recess, when laminating with bar spring 2, reduce the wearing and tearing to bar spring 2.

Specifically, as shown in fig. 1 and 3, the head of the fastener 10 is in an L-shaped structure, and the head of the fastener 10 in the L-shaped structure can be attached to the right end of the fastener seat 9.

Specifically, as shown in fig. 1 and 2, a sliding sleeve 6 is welded at the left part of the upper end of a base 1, a sliding rod 7 is embedded in the sliding sleeve 6 in a sliding manner, a baffle 8 is welded at the upper end of the sliding rod 7, a bar-shaped spring 2 is arranged above the base 1, the head and the tail of the bar-shaped spring 2 are respectively placed at the upper ends of the baffle 8 and a buckling seat 9, and wavy lines are installed at the bottom end of the baffle 8, so that friction between the steel rail and the sliding sleeve is increased.

The working principle is as follows: when in use, firstly, a user needs to pull the baffle 8 upwards to enable the slide rod 7 at the lower end of the baffle 8 to slide upwards along the sliding sleeve 6, when the distance between the baffle 8 and the base 1 is in due time with the thickness of the side wing of the steel rail, the steel rail can be clamped between the base 1 and the baffle 8, at the moment, the bar spring 2 can tightly lock the steel rail on the base 1 through the baffle 8, the contact area of the spring buckle when the steel rail is locked with the buckle can be increased, under the condition that the pressure of the bar spring 2 to the steel rail is unchanged, the friction force between the steel rail and the buckle is improved, the baffle 8 is prevented from moving transversely relative to the steel rail, thereby improving the stability of the device when the steel rail is locked, secondly, the limiting rod 4 is pulled upwards, the tail part of the bar spring 2 in an M-shaped structure passes through the limiting rod 4 and is placed at the upper end of the buckle seat 9, the fastener 10 is rotated, the head part of the, through swivel nut and bolt, with fastener 10 and the closure of detaining seat 9, bar spring 2 is arranged in the recess that 5 bottoms of mount pad were seted up this moment, through swivel nut and bolt with bar spring 2 and the inseparable lock of mount pad 5, realized that this spring buckle is when 2 buckles to bar spring, can restrict bar spring 2 and move on the horizontal direction along base 1 to bar spring 2's middle part and afterbody are all buckled, have further promoted the buckle to 2 stability when buckles of bar spring.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
