Description

Technical Field

[0001] The utility model relates to the field of locking parts, in particular to a petal nut. Background Art

[0002] Nuts are nuts, parts that are screwed together with bolts or screws for fastening. All manufacturing machinery must use a kind of petal nut element. According to different materials, it is divided into several types such as carbon steel, stainless steel, and non-ferrous metals (such as copper). Nuts are parts that tightly connect mechanical equipment. Through the inner thread, nuts and bolts of the same specifications can be connected together. There are two ways to form the outer knurling of embedded copper nuts. One kind of petal nut is made of copper raw materials and then produced on the upper equipment. Generally, the pattern of this method is straight. The other kind of petal nut is made of smooth round copper materials and tapped and embossed directly during the production process. This processing method can produce some non-standard knurled copper nuts. The shape of the embedded copper nut embossing can be selected by the user, such as mesh, eight-shaped embossing, herringbone embossing and other knurling patterns. There are many types of nuts, and there are nuts of different materials. Each type of nut has different specifications. Each screw also has its own mechanical properties and functions. It is usually made of reusable medium carbon steel.

[0003] When traditional nut petals are in use, the screw rotates to drive the thin sheets at the connection inward, and the soft sheets are bent and overlapped, so that the petal nut completes the clamping of the opened hole. However, these petal nuts will inevitably be removed during the maintenance process, and these soft sheets may be damaged after repeated expansion and contraction, resulting in the inability to continue the installation later, causing cost waste. In view of this, a petal nut is proposed. Utility Model Content

[0004] In order to solve at least one of the above-mentioned technical shortcomings, the utility model provides a petal nut, including an upper top plate, a rotatable locking petal plate connected below the upper top plate, the locking petals are connected in pairs through connecting pieces below, and a tightening nut is connected below the locking petals.

[0005] Furthermore, connecting grooves are provided on both sides of the locking petal, the inner wall of the connecting groove is provided with a through hole, a pressure rod is provided at the bottom of the upper top plate, and round rods symmetrical on both sides are provided at the bottom of the pressure rod, and the round rods are plugged into the through holes on the inner wall of the connecting groove.

[0006] Furthermore, four circular holes arranged in a circumferential array are arranged at the bottom of the upper top plate, and matching springs are connected in the circular holes. The bottom of the spring is fixed to the top of the pressure rod, and the diameter of the circular hole is equal to that of the pressure rod.

[0007] Furthermore, the outer wall of the upper top sheet is also provided with rectangular extension sheets arranged in a circumferential array.

[0008] Furthermore, protruding connecting shafts are provided on both sides of the upper and lower sides of the connecting piece, and the upper and lower connecting shafts are respectively plugged into the bottom of the upper locking petals and the top of the lower locking petals arranged in pairs. A matching shaft seat is provided on the top of the tightening nut, and the shaft seat is plugged into the bottom of the locking petals arranged below.

[0009] Beneficial effect: Align the upper top plate with the opened hole and use pliers to clamp the extension plate, screw in the matching screw downward, and when the screw is connected to the clamping nut, the screw continues to move downward, causing the two locking petals connected by the connecting piece to continue to move downward, so that the distance between the clamping nut and the upper top plate is gradually shortened. When the locking petals are gradually flush with the bottom of the upper top plate, the locking petals will simultaneously drive the four pressure rods at the bottom of the upper top plate to drive the spring into the preset aperture, thereby providing a downward advance pressure to the flush locking petals to improve the tightening effect of the nut.

[0010] The realization of the purpose, functional features and advantages of the present invention will be further described in conjunction with embodiments and with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0014] Please refer to Figure 1 to Figure 2 ;

[0015] The present embodiment provides a petal nut, including an upper top plate 1, a rotatable locking petal 2 is connected below the upper top plate 1, the locking petals 2 are connected in pairs through a connecting piece 3, and a compression nut 4 is connected below the locking petals 2; Figure 1 and Figure 2, connecting grooves 201 are provided on both sides of the locking petal 2, and the inner wall of the connecting groove 201 is provided with a through hole that is penetrated, and a pressure rod 103 is provided at the bottom of the upper top plate 1, and a round rod symmetrical on both sides is provided at the bottom of the pressure rod 103, and the round rod is plugged into the through hole on the inner wall of the connecting groove 201, and four circular holes arranged in a circumferential array are provided at the bottom of the upper top plate 1, and a matching spring 102 is connected in the circular hole, and the bottom of the spring 102 is fixedly arranged with the top of the pressure rod 103, and the diameter of the circular hole is equal to that of the pressure rod 103, and the outer wall of the upper top plate 1 is also provided with a rectangular extension piece 101 arranged in a circumferential array. At the same time, protruding connecting shafts are provided on the upper and lower sides of the connecting piece 3, and the upper and lower connecting shafts are respectively plugged with the bottom of the upper locking petal 2 arranged in pairs and the top of the locking petal 2 arranged below, and the top of the tightening nut 4 is provided with a matching shaft seat 401, and the shaft seat 401 is plugged into the bottom of the locking petal 2 arranged below;

[0016] In a specific embodiment, the number of extension pieces 101 is four, which is convenient for clamping with tool pliers to prevent instability when clamping the upper top piece 1. The upper top piece 1 is aligned with the opened hole and the extension piece 101 is clamped using pliers, and the matching screw is screwed in downward. When the screw is connected to the clamping nut 4, the screw continues to move downward, causing the two locking petals 2 connected by the connecting piece 3 to continue to move downward, so that the distance between the clamping nut 4 and the upper top piece 1 is gradually shortened. When the locking petal 2 is gradually flush with the bottom of the upper top piece 1, the locking petal 2 will simultaneously drive the four pressure rods 103 at the bottom of the upper top piece 1 to drive the spring 102 into the preset aperture, thereby simultaneously providing a downward advance pressure to the flush locking petal 2 to improve the tightening effect of the nut.

[0017] Furthermore, the added thickness of the two locking flaps 2 is smaller than the length of the connecting piece 3 , so as to prevent the locking flap 2 from getting stuck when it is almost flush with the bottom end of the upper top plate 1 .
