Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
Referring to fig. 1 to 5, the present embodiment provides a technical solution: a barbell capable of being quickly disassembled and assembled comprises a main rod 2, a plurality of weight plates 3 are assembled at two ends of the main rod 2 through a quick assembly part 1, the quick assembly part 1 comprises a fixing sleeve 1.10, two pressure plate covers 1.5 which are oppositely arranged are arranged in one end of the fixing sleeve 1.10, each pressure plate cover 1.5 protrudes out of the fixing sleeve 1.10, two sides of each pressure plate cover 1.5 are respectively connected with a workpiece taking pressure plate 1.4, the workpiece taking pressure plates 1.4 on the upper side and the lower side of the same side are clamped on the same shifting block 1.3, the two shifting blocks 1.3 are respectively clamped on the two shifting blocks 1.3 through a reset spring 1.2 and a pressure spring positioning plate 1.1, the pressure spring positioning plate 1.1 is fixed on the fixing sleeve 1.10, one end of each pull rod 1.6 is respectively clamped on the two shifting blocks 1.3, a rotatable weight plate stop block 1.7 is arranged in each pull rod 1.6, the two weight plate stop blocks 1.7 which are oppositely arranged up and down are in a group, the upper end and the lower end of each weight, the tail end of the fixed sleeve 1.10 is provided with an end sleeve 1.9.
The two weight plate stoppers 1.7 which are oppositely arranged up and down are connected through a cylindrical pin 1.7.4, a torsion spring 1.8 is sleeved on the cylindrical pin 1.7.4, the two weight plate stoppers 1.7 rotate by taking the cylindrical pin 1.7.4 as a center, namely, the other ends of the two weight plate stoppers 1.7 can be opened or closed.
The quick assembly and disassembly of the weight plates are realized by the following modes: the pressing plate cover 1.5 is pinched inwards, at the moment, the pressing plate cover 1.5 drives the part taking pressing plate 1.4 to move the shifting block 1.3 rightwards, the shifting block 1.3 and the pull rod 1.6 are assembled together through the assembling hole 1.6.1, and at the moment, the pull rod 1.6 also moves rightwards synchronously. A plurality of holes 1.6.2 with slopes are arranged on the pull rod 1.6, each hole 1.6.2 with slopes corresponds to the weight plate stop 1.7, and the boss 1.7.1 on the weight plate stop 1.7 protrudes out of the hole 1.6.2 with slopes. When the pull rod 1.6 moves rightwards, the boss 1.7.1 on the weight plate stop block 1.7 is pressed downwards through the hole 1.6.2 with the slope on the pull rod, so that the weight plate stop block 1.7 rotates downwards along the cylindrical pin 1.7.4 with immovable central positioning, the top end of the weight plate stop block 1.7 is the outer boss 1.7.2, when the outer boss 1.7.2 rotates downwards and is lower than the outer contour of the fixed sleeve 1.10, the weight plate 3 can be assembled or disassembled smoothly due to no shielding piece, and the purpose of quick disassembly and assembly can be achieved. After the weight plates 3 are assembled, the pressing plate cover 1.5 is loosened, the reset pressure spring 1.2 fixed on the pressure spring positioning plate 1.1 pushes the shifting block 1.3 to push out the workpiece taking pressing plate 1.4 leftwards, and therefore the pressing plate cover 1.5 is jacked up to restore the original position. Meanwhile, the pull rod 1.6 also returns to the original position leftwards, at the moment, the weight plate stop block 1.7 returns to the original position due to the elasticity of the torsion spring 1.8, and the outer boss 1.7.2 is exposed out of the outer contour of the fixed sleeve 1.10 and can block the weight plate 3 from sliding out.
In order to prevent misoperation or failure of the torsion spring 1.8 and cause personal injury caused by falling of the counterweight weight plate 3 in use, the anti-loosening boss 1.6.3 is particularly arranged on the pull rod 1.6. If, as shown in fig. 5, a malfunction or failure of the torsion spring occurs during use, such that the weight plate stops 1.7 move inwardly in the direction of the arrows, the tension rods 1.6 are held in place by the pressure of the return compression spring 1.2. The lower corner 1.7.3 of the weight plate stop 1.7 is blocked by the anti-loosening boss 1.6.3 on the pull rod 1.6, so that the weight plate stop 1.7 is guaranteed not to move any more, and the weight plate 3 is guaranteed not to drop. When preparing to dismantle counter weight plate 3, because pull rod 1.6 just drives weight plate dog 1.7 internal rotation when pulling right, when lower angle 1.7.3 of weight plate dog 1.7 moved to the position of locking boss 1.6.3 on original pull rod 1.6, locking boss 1.6.3 had been along with pull rod 1.6 and has been moved to the right side this moment, has left the neutral position for lower angle 1.7.3 of weight plate dog 1.7, so weight plate dog 1.7 can rotate to the position smoothly this moment. At this time, the outer boss 1.7.2 rotates downward to be lower than the outer contour of the fixed sleeve 1.10, so that the weight plates 3 can be smoothly taken down.
In order to ensure the strength of the product, the soft end sleeve is arranged at the outermost end of the quick-release assembly, and the effects of buffering and preventing collision damage can be achieved.
In order to guarantee that the product is used smoothly, clearance fit is adopted in the assembly of quick detach sub-assembly and mobile jib, and fixed cover 1.10's link is inside to be equipped with fixed boss 1.10.1 promptly, is equipped with fixed recess 2.1 on the terminal surface of mobile jib 2, and fixed boss 1.10.1 is clearance fit with fixed recess 2.1, guarantees that the quick detach sub-assembly can freely rotate on the mobile jib but can not drop. And the weight plates adopt the conventional integral structure, so that the eccentric phenomenon caused by an open structure is avoided.
The locking structures capable of being locked and loosened quickly are designed on the two sides of the barbell rod, so that the weight plates can be assembled and disassembled quickly, and the locking bosses are arranged on the locking structures, so that the weight plates cannot fall off due to spring failure or misoperation in the using process. The invention not only can save the time for users to adjust the weight plates, but also can improve the safety and comfort of use.
