Description
Technical Field
[0001] The utility model relates to the field of home furnishing manufacturing, in particular to a connection structure of a swing rod and a telescopic core rod. Background Art
[0002] The existing Chinese utility model patent with publication number CN218355243U and titled "An electromagnetically driven swinging iron frame" discloses that the driving part includes a driving plate fixed to the outer peripheral surface of the telescopic core rod, the driving plate is made of iron, and the driving plate is located between two guide seats on the same side. The front end face of the driving plate is fixed to a connecting rod parallel to the telescopic core rod, and the front side of the connecting rod is fixed to a driving shaft perpendicular to the telescopic core rod. Bearings are installed on both sides of the driving shaft, and a driving block is arranged on the outside of the bearing. The bottom of the driving block is provided with a slide groove with an open bottom side, and the slide groove is used for the rolling of the bearing. The top of the driving block is fixed to the driving rod. However, when the bearing rolls in the slide groove, it can only fit with the side wall on one side of the slide groove, and a gap needs to be left with the side wall on the other side of the slide groove. This gap causes the telescopic core rod and the driving rod to not move synchronously, and there is a sense of jamming, which affects the product quality. Utility Model Content
[0003] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a connection structure between a swing rod and a telescopic core rod, which can ensure the synchronization of the movement of the telescopic core rod and the swing rod, thereby eliminating the sense of jamming and improving product quality.
[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the connection structure of the swing rod and the telescopic mandrel of the utility model is:
[0005] A connection structure between a swing rod and a telescopic core rod comprises a telescopic core rod and a swing rod, wherein a transmission rod is arranged between the telescopic core rod and the swing rod, wherein one end of the transmission rod is pivotally connected to the telescopic core rod through a first connecting piece, and the other end of the transmission rod is pivotally connected to the swing rod through a second connecting piece.
[0006] Preferably, the first connecting member is a rod end joint bearing, which is fixed to the end of the telescopic mandrel and is pivotally connected to the transmission member via a bolt assembly.
[0007] Preferably, the second connecting member includes a connecting piece 1 fixedly connected to the swing rod, the connecting piece 1 is fixedly connected to a connecting piece 2, and the connecting piece 2 is pivotally connected to the transmission rod through a rivet.
[0008] Preferably, a bearing is sleeved on the outer side of the rivet, and the bearing is installed on the transmission rod or the connecting block.
[0009] Preferably, a limiting boss is provided on one side edge of the bearing outer ring, and a washer is provided on the end surface of the bearing inner ring opposite to the limiting boss.
[0010] Compared with the prior art, the utility model has the following advantages:
[0011] 1. The telescopic mandrel and the swing rod are connected more closely through the transmission rod to ensure the synchronization of the movement of the telescopic mandrel and the swing rod, thereby eliminating the sense of jamming and improving product quality. In addition, the structure is simplified and the production cost is reduced.
[0012] 2. The telescopic mandrel is connected to the transmission rod through a rod end joint bearing, which can reduce the difficulty of assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Among them, 1 is a telescopic core rod, 11 is a first connecting piece, 2 is a swing rod, 21 is a second connecting piece, 211 is a connecting piece 1, 212 is a connecting piece 2, 3 is a transmission rod, 31 is a through hole, 4 is a bolt assembly, 5 is a rivet, 6 is a bearing, 61 is a limiting boss, 62 is a washer, 7 is a winding coil, and 8 is a linear bearing. DETAILED DESCRIPTION
[0017] The present invention is further explained below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that these implementation methods are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading the present invention, various equivalent forms of modifications to the present invention by those skilled in the art all fall within the scope defined by the claims attached to this application.
[0018] like Figure 1-3As shown, a connection structure of a swing rod and a telescopic mandrel comprises a telescopic mandrel 1 and a swing rod 2, a transmission rod 3 is arranged between the telescopic mandrel and the swing rod, the right end of the transmission rod is pivotally connected to the telescopic mandrel through a first connecting member 11, the first connecting member is a rod end joint bearing, the rod end joint bearing is fixed to the end of the telescopic mandrel, the rod end joint bearing is pivotally connected to the transmission member through a bolt assembly 4, the left end of the transmission rod is pivotally connected to the swing rod through a second connecting member 21, the second connecting member comprises a connecting piece 1 211 welded to the swing rod, the connecting piece 1 is fixedly connected to the connecting piece 212 by bolts, and the connecting piece The second connecting piece is pivotally connected to the transmission rod through a rivet 5, and a bearing 6 is sleeved on the outer side of the rivet. The bearing is installed on the transmission rod. A through hole 31 for accommodating the bearing is provided on the transmission rod. A limiting boss 61 is welded on the edge of the outer ring of the bearing facing away from the transmission rod. The outer diameter of the limiting boss is larger than the diameter of the through hole, so that the rivet can rivet the connecting piece 2 and the transmission rod together. A washer 62 is welded on the end face of the inner ring of the bearing opposite to the limiting boss. The washer separates the connecting piece 2 and the transmission rod to avoid direct contact between the connecting piece 2 and the transmission rod, which is beneficial to the relative rotation between the two, reduces the mutual wear between the two, and improves the service life.
[0019] The specific working process and principle of the utility model are as follows: the winding coil 7 is energized to generate a magnetic field, the telescopic mandrel is attracted to move to the right along the linear bearing 8, the rod end joint bearing pulls the transmission part, the transmission part pulls the swing rod to move to the upper right to a certain height, the winding coil is powered off, the telescopic mandrel loses its attraction, the swing rod falls back due to gravity and moves to the upper left, at which time the transmission part pulls the telescopic mandrel to move to the left, so that the swing rod can perform a "pendulum motion". The utility model tightly connects the swing rod and the telescopic mandrel through the transmission rod, has high synchronization, no jamming during operation, improves product quality, and has a simpler structure, saving manufacturing costs.
