Description

Technical Field

[0001] This utility model relates to the technical field of anti-loosening structures, and in particular to wedge block positioning anti-loosening structures. Background Technology

[0002] The wedge-shaped positioning and anti-loosening structure is a mechanical structure that utilizes the deformation characteristics of a wedge-shaped part to achieve positioning and anti-loosening. The wedge mechanism is an important mechanical principle, its working principle based on the deformation characteristics of a wedge-shaped part. A wedge-shaped part typically has a triangular shape with an included angle of less than 90 degrees between its two sides. When the wedge-shaped part is subjected to external force, its inclined surface deforms, thereby transmitting, positioning, and fixing the force along the inclined surface. Because the wedge can only move linearly and cannot rotate, its degrees of freedom are zero, which ensures the accuracy and stability of force transmission, positioning, and fixing.

[0003] For example, in the prior art represented by the anti-loosening structure disclosed in the utility model patent with application number CN202323646241.7, its main structure includes a fixing plate, a threaded groove, an anti-loosening ring, a top groove, an insert rod, a locking block, a limiting groove, and a limiting strip. The anti-loosening structure achieves its function through the cooperation of the fixing plate, threaded groove, anti-loosening ring, top groove, insert rod, locking block, limiting groove, and limiting strip.

[0004] Traditional wedges are easily shaken out during vibration, leading to their loss, and they are also inconvenient for replacing the screen. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a wedge-shaped anti-loosening gasket that prevents the screw from loosening and falling off due to vibration. This anti-loosening gasket has a unique multi-functional design that can prevent the spontaneous loosening and weakening of the bolts connected by the anti-loosening gasket. When there is insufficient space for longitudinal hammering of the wedge block and hammering is not possible, the screw can be removed, the limiting plate can be removed, and the wedge block can be pried out laterally with a pry bar, thus improving the practicality of the equipment.

[0006] This utility model's wedge positioning and anti-loosening structure includes an angle iron; it also includes a limiting plate, a nut, an anti-loosening washer, and a screw. The nut is welded to the angle iron, and a limiting plate is fixed to one side of the nut with a screw to restrict the lateral displacement of the wedge. Because vibration can cause the screw to loosen and fall off, we use an anti-loosening washer. This anti-loosening washer adopts a unique multi-functional design to prevent the spontaneous bolts connected to the anti-loosening washer from loosening and weakening. It has both excellent Lodilock wedge effect and special spring effect, which can provide additional safety for applications operating under extreme conditions. When replacing the screen, if there is insufficient space for longitudinal striking of the wedge and hammering is not possible, the screw can be removed, the limiting plate can be removed, and the wedge can be pried out laterally with a pry bar, improving the practicality of the equipment.

[0007] Preferably, the utility model also includes an angle iron, which is L-shaped in cross section; the angle iron supports the nut, and the L-shaped cross section design helps to enhance the overall stability and support capacity of the structure and improve the practicability of the equipment.

[0008] Preferably, the utility model also includes a limiting plate, which is located at the right side of the angle iron and the nut; the limiting plate limits the lateral displacement of the wedge, thereby improving the practicability of the equipment.

[0009] Preferably, the utility model also includes a nut, which is located on the angle iron, at the left side of the limiting plate, and is welded to the angle iron; the interior of the nut is provided with threads; the wedge anti-loosening structure is realized through the cooperation of the nut, the lock washer and the screw rod, thereby improving the practicability of the equipment.

[0010] Preferably, the utility model also includes a lock washer, which is installed on the screw rod and located at the right side of the limiting plate; the lock washer is designed in a unique multifunctional manner, which can prevent the spontaneous loosening and attenuation of the screw rod connection; the lock washer has excellent LoeTlo wedge effect and special spring effect, which can provide additional safety protection for applications operating under extreme conditions, thereby improving the practicability of the equipment.

[0011] Preferably, the utility model also includes a screw rod, which is provided with threads and has a limiting plate at the right part and is rotatably installed in the interior of the nut at the left part; the screw rod is rotated into the interior of the nut by the staff, and the limiting plate limits the lock washer, thereby realizing the function of the lock washer and improving the practicability of the equipment.

[0012] Compared with the prior art, the utility model has the beneficial effects that: because the screw rod may be shaken off in the vibration, the lock washer is adopted, which is designed in a unique multifunctional manner, which can prevent the spontaneous loosening and attenuation of the lock washer connection; the lock washer has excellent LoeTlo wedge effect and special spring effect, which can provide additional safety protection for applications operating under extreme conditions; when the screen is disassembled and replaced, the wedge cannot be used for hammering due to insufficient longitudinal knocking space, at this time, the screw rod can be removed, the limiting plate can be removed, and the wedge can be pried out horizontally with a crowbar, thereby improving the practicability of the equipment.
