Description

Technical Field

[0001] The invention relates to the field of tie rod joint mechanisms, and more particularly to a quick-release spherical tie rod joint assembly. Background Art

[0002] At present, the connection method between the known pull rods is to connect them in series through pin holes. The two pull rods are connected by pins to achieve synchronous movement of the pull rods, which can realize the forward and backward movement of the pull rods. However, with the upgrading of the industry and the multifunctionalization of equipment, the pull rods connected by pin holes are very troublesome to disassemble and assemble, and professional tools are required. Especially for components with high replacement efficiency requirements, higher standards are put forward for the convenience of disassembly of equipment. Generally, the pull rod joints cannot be quickly disassembled, resulting in joints that need to be frequently disassembled, low disassembly efficiency and poor convenience. Summary of the invention

[0003] The object of the present invention is to provide a quick-release spherical tie rod joint assembly, thereby solving the problems of low assembly and disassembly efficiency and poor convenience of the tie rod joint mechanism in the prior art.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A quick-release ball-pull rod joint assembly is provided, comprising: an axially extending driving rod; an axially extending driven rod; a ball head connected to the top end of the driven rod; an axially extending ball seat, one end of the ball seat is connected to the driving rod, and the other end has a groove for accommodating the ball head and part of the driven rod, the top of the groove is open upward to facilitate the ball head and the driven rod to fall into the groove from above; and a limit block sleeved on the outer periphery of the ball seat; wherein the limit block is movable along the axial direction of the ball seat to open or close the groove, thereby realizing quick disassembly and assembly of the ball-pull rod joint assembly.

[0006] Preferably, the driving rod is threadedly connected to the ball seat.

[0007] Preferably, a locking nut is provided between the driving rod and the ball seat.

[0008] Preferably, the movement of the limiting block relative to the ball seat includes translational sliding and rotational sliding.

[0009] Preferably, the follower rod has a cylindrical profile.

[0010] Preferably, the outer diameter of the ball head is larger than the radial dimension of the driven rod.

[0011] Preferably, the outer surface of the limiting block has a chamfer.

[0012] According to the present invention, a quick-release spherical tie rod joint assembly is provided, which can not only tightly connect the tie rods, but also quickly unlock and separate the joints without tools, and is particularly suitable for tie rod connections with low coaxiality requirements.

[0013] In summary, the present invention provides a quick-release spherical tie rod joint assembly with improved disassembly and assembly efficiency, good portability, and a wide range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention is further described below in conjunction with specific examples. It should be understood that the following examples are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0018] Combination Figure 1 , Figure 2 , Figure 3 As shown in FIG. 1 , a quick-release ball-type tie rod joint assembly according to a preferred embodiment of the present invention is provided, comprising: a driving rod 1, a locking nut 2, a stopper 3, a ball seat 4, a driven rod 5 and a ball head 6. The ball head 6 is connected to the top of the driven rod 5, and one end of the ball seat 4 (i.e. Figure 1 The left end) is connected to the driving rod 1, and the other end (i.e. Figure 1 The right end) has a slot 41 for accommodating the ball head 6 and part of the driven rod 5, and the top of the slot 41 is open upward to facilitate the ball head 6 and the driven rod 5 to fall into the slot 41 from above; the limit block 3 is sleeved on the outer periphery of the ball seat 4 and can be moved along the axial direction of the ball seat 4, thereby opening or closing the slot 41 to realize the rapid disassembly and assembly of the spherical pull rod joint assembly.

[0019] According to the preferred embodiment, the driving rod 1 is threadedly connected to the ball seat 4, and the locking nut 2 is disposed between the driving rod 1 and the ball seat 4 to further lock the driving rod 1. Preferably, one end of the driving rod 1 has an external thread, one end of the ball seat 4 has an internal thread, and the locking nut 2 is sleeved on the outer surface of the end of the driving rod 1 and then locked by the ball seat 4.

[0020] According to the present invention, the movement of the limit block 3 relative to the ball seat 4 includes two modes: translation sliding and rotation sliding. It should be understood that as long as the axial movement of the limit block 3 can be achieved, the fast disassembly and assembly of the driven rod 5 can be achieved.

[0021] According to the preferred embodiment, the driven rod 5 has a cylindrical contour and the ball head 6 has a spherical contour.

[0022] Preferably, the outer diameter of the ball head 6 is larger than the radial dimension of the driven rod 5 , thereby limiting the driven rod 5 and preventing the driven rod 5 from axially coming out.

[0023] Also preferably, the outer surface of the limit block 3 has a chamfer to avoid scratching the operator, so as to further improve the safety of the component.

[0024] According to the quick-release spherical pull rod joint assembly provided in the above preferred embodiment, when the limit block 3 is located at the left end in the figure, as shown in FIG. Figure 2 As shown in FIG. 1 (i.e., the first state), the slot 41 is exposed. At this time, the ball head 6 and the driven rod 5 connected together are dropped into the ball seat 4 from above, and then the stop block 3 is moved to the connection between the ball head 6 and the ball seat 4, as shown in FIG. Figure 3 As shown (i.e., the second state), the ball head 6 can be constrained in the ball seat 4 to achieve the connection between the driven rod 5 and the driving rod 1. It should be understood that the reverse operation can achieve the rapid release of the driven rod 5 and the driving rod 1.

[0025] The above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. The above embodiments of the present invention can also be modified in various ways. All simple, equivalent changes and modifications made according to the claims and the description of the present invention fall within the scope of protection of the claims of the present invention. The contents not described in detail in the present invention are all conventional technical contents.
