Description

A kind of plate-shaped springs

Technical field

This utility model belongs to mechanical appliance technical field, is specifically related to a kind of plate-shaped springs.

Background technology

nullAt present，Plate-shaped springs is because of its superior load and guidance quality，It is widely used in car body elasticity original paper，In order to prevent plate-shaped springs at subpackage、In transport and vehicle traveling process, shell fragment produces dislocation，Generally sandwich at plate-shaped springs upper mounting plate shape spring，Common plate-shaped springs sandwiches，Including U type alligator clamp and the steel plate bullet shell fragment being mounted in it，Its U type alligator clamp is made up of bottom and two left and right arms，Steel plate bullet shell fragment is loaded in the U type groove of U type alligator clamp，The bottom rivet of steel plate bullet shell fragment is fixed on the U type trench bottom of U type alligator clamp，The left and right arms of U type alligator clamp uses screw to connect，If the plate-shaped springs adopted the structure sandwiches，The shell fragment that misplaces in vehicle traveling process directly will contact with the side of U type alligator clamp，Owing to U type alligator clamp is metal material，Dislocation shell fragment is also metal material，Rigidity friction will be produced between them，Send audible noise，Have a strong impact on car comfort，U-shaped alligator clamp can only solve the movement of shell fragment fore-and-aft direction simultaneously，The movement on shell fragment left and right directions can not be solved，Therefore，Need a kind of can solve shell fragment left and right directions move and be possible to prevent produce audible noise plate-shaped springs.

Utility model content

The purpose of this utility model is to provide a kind of plate-shaped springs, with the problem solving to propose in above-mentioned background technology.

For achieving the above object, this utility model following technical scheme of offer: a kind of plate-shaped springs, including the 4th shell fragment, described 4th shell fragment two ends are fixed with grasswort respectively, the 3rd shell fragment has been stacked gradually above described 4th shell fragment, second shell fragment and the first shell fragment, described 3rd shell fragment and the 4th shell fragment are connected by the first locating part colligation, described first shell fragment, second shell fragment, 3rd shell fragment and the 4th shell fragment are connected by the second locating part colligation, described first shell fragment, second shell fragment, in the middle part of 3rd shell fragment and the 4th shell fragment, side is all fixed with spacing preiection, described spacing preiection passes middle locating part opening, and be slidably connected with locating part.

Preferably, it is equipped with oil groove inside described first locating part and the second locating part.

Preferably, it is provided with inside described middle locating part between oil groove, and described middle locating part and spacing preiection and is provided with oil clearance.

Preferably, it is fixed with potassium steel wearing layer inside described middle locating part.

Technique effect of the present utility model and advantage: this plate-shaped springs, pass through spacing preiection, it is possible to prevent shell fragment movement in the lateral direction, simultaneously because be provided with oil groove inside the first locating part and the second locating part, it is possible to prevent shell fragment during movement and directly contacts between the first locating part and the second locating part, decrease friction, the generation of noise can be reduced simultaneously, oil groove it is again provided with inside locating part in Tong Shi, and it is provided with oil clearance between middle locating part and spacing preiection, equally reduces the generation of noise.Therefore, this utility model is reasonable in design, by a series of structure, so that the shell fragment of plate-shaped springs will not produce the movement on left and right directions, can also reduce the generation of noise simultaneously, improve impression when people use.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model；

Fig. 2 is middle locating part sectional view of the present utility model.

In figure: 1 grasswort, 2 first locating parts, 3 second locating parts, 4 spacing preiections, locating part, 6 first shell fragments, 7 second shell fragments, 8 the 3rd shell fragments, 9 the 4th shell fragments in 5.

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.

nullThis utility model provides a kind of plate-shaped springs as shown in Figure 1-2，Including the 4th shell fragment 9，Described 4th shell fragment 9 two ends are fixed with grasswort 1 respectively，The 3rd shell fragment 8 has been stacked gradually above described 4th shell fragment 9、Second shell fragment 7 and the first shell fragment 6，Described 3rd shell fragment 8 and the 4th shell fragment 9 are connected by the first locating part 2 colligation，Described first shell fragment 6、Second shell fragment 7、3rd shell fragment 8 and the 4th shell fragment 9 are connected by the second locating part 3 colligation，It is equipped with oil groove inside described first locating part 2 and the second locating part 3，Described first shell fragment 6、Second shell fragment 7、In the middle part of 3rd shell fragment 8 and the 4th shell fragment 9, side is all fixed with spacing preiection 4，Described spacing preiection 4 is through middle locating part 5 opening，And be slidably connected with locating part 5，It is fixed with potassium steel wearing layer inside described middle locating part 5，It is provided with oil groove inside described middle locating part 5，And it is provided with oil clearance between described middle locating part 5 and spacing preiection 4.

This plate-shaped springs, by spacing preiection 4, it is possible to prevent shell fragment movement in the lateral direction, simultaneously because be provided with oil groove inside the first locating part 2 and the second locating part 3, it be possible to prevent shell fragment during movement and directly contact between the first locating part 2 and the second locating part 3, decreasing friction, the generation of noise can be reduced simultaneously, it is again provided with inside locating part 5 in Tong Shi being provided with oil clearance between oil groove, and middle locating part 5 and spacing preiection 4, equally reduces the generation of noise.Therefore, this utility model is reasonable in design, by a series of structure, so that the shell fragment of plate-shaped springs will not produce the movement on left and right directions, can also reduce the generation of noise simultaneously, improve impression when people use.

Last it is noted that the foregoing is only preferred embodiment of the present utility model; it is not limited to this utility model; although this utility model being described in detail with reference to previous embodiment; for a person skilled in the art; technical scheme described in foregoing embodiments still can be modified by it; or wherein portion of techniques feature is carried out equivalent; all within spirit of the present utility model and principle; the any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
