Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be combined with each other. The application will be described in detail below with reference to the drawings in connection with embodiments.
Referring to fig. 1 to 5 for specific structure, the present embodiment provides a technical solution: the utility model provides a quick assembly disassembly barbell, including mobile jib 2, a plurality of counter weight plates 3 have been assembled through quick sub-assembly 1 in the both ends of mobile jib 2, quick sub-assembly 1 includes fixed cover 1.10, be equipped with two clamp plate covers 1.5 of relative setting in the one end of fixed cover 1.10, every clamp plate cover 1.5 protrusion fixed cover 1.10, two clamp plate covers 1.5 both sides all are connected with and get a clamp plate 1.4, get a clamp plate 1.4 card from top to bottom on same shifting block 1.3 from same side, two shifting blocks 1.3 pass through reset spring 1.2 and pressure spring locating plate 1.1, pressure spring locating plate 1.1 is fixed on fixed cover 1.10, the one end of two pull rods 1.6 is blocked respectively on two shifting blocks 1.3, be equipped with can rotatory weight plate dog 1.7 in the pull rod 1.6, two relatively setting up and be a set of weight plate dog 1.7 from top to bottom, the upper and lower extreme of every weight plate dog 1.7 wears out fixed cover 1.10, can be equipped with the counter weight plate locating plate 1.1.1 through rotatory end cover 1.7, it is equipped with the counter weight plate 1.10 to dismantle through the rotation end cover 1.3.
The two weight plate check blocks 1.7 which are arranged up and down oppositely are connected through the cylindrical pin 1.7.4, the cylindrical pin 1.7.4 is sleeved with the torsion spring 1.8, and the two weight plate check blocks 1.7 rotate by taking the cylindrical pin 1.7.4 as the center, namely, the other ends of the two weight plate check blocks 1.7 can be opened or closed.
The weight plate is quickly assembled and disassembled by the following modes: the pressing plate cover 1.5 is pinched inwards, at the moment, the pressing plate cover 1.5 drives the workpiece 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 assembly hole 1.6.1, and at the moment, the pull rod 1.6 also moves rightwards synchronously. The pull rod 1.6 is provided with a plurality of holes 1.6.2 with slopes, each hole 1.6.2 with slopes corresponds to the weight plate block 1.7, and the boss 1.7.1 on the weight plate block 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 check block 1.7 is pressed downwards through the hole 1.6.2 with the slope, so that the weight plate check block 1.7 rotates downwards along the cylindrical pin 1.7.4 with the fixed center, the top end of the weight plate check block 1.7 is the outer boss 1.7.2, and when the outer boss 1.7.2 rotates downwards to be 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, thereby achieving the aim of quick disassembly. When the weight plate 3 is 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 the taking pressing plate 1.4 out leftwards, so that the pressing plate cover 1.5 is jacked to restore to the original position. Meanwhile, the pull rod 1.6 also returns to the left to return to the original position, 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 exposes out of the outer contour of the fixed sleeve 1.10, so that the weight plate 3 can be blocked from sliding out.
In order to prevent the weight plate 3 from falling off and personal injury caused by misoperation or failure of the torsion spring 1.8, a locking boss 1.6.3 is arranged on the pull rod 1.6. As shown in fig. 5, if a malfunction or failure of the torsion spring occurs in use, the weight plate block 1.7 is moved inward in the direction of the arrow, at which time the tie rod 1.6 remains in place due to the pressure of the return compression spring 1.2. The lower corner 1.7.3 of the weight plate block 1.7 is blocked by the anti-loose boss 1.6.3 on the pull rod 1.6, thereby ensuring that the weight plate block 1.7 does not move any more and ensuring that the weight plate 3 does not fall off. When the weight plate 3 is to be detached, the pull rod 1.6 pulls rightwards to drive the weight plate baffle block 1.7 to rotate inwards, and when the lower corner 1.7.3 of the weight plate baffle block 1.7 moves to the position of the anti-loosening boss 1.6.3 on the original pull rod 1.6, the anti-loosening boss 1.6.3 moves to the right side along with the pull rod 1.6, and a neutral position is reserved for the lower corner 1.7.3 of the weight plate baffle block 1.7, so that the weight plate baffle block 1.7 can rotate smoothly. At this time, the outer boss 1.7.2 rotates downward to be lower than the outer contour of the fixing sleeve 1.10, so that the weight plate 3 can be smoothly taken down.
In order to ensure the strength of the product, a soft end sleeve is arranged at the outermost end of the quick-release assembly, so that the effect of buffering and preventing collision damage can be achieved.
In order to ensure smooth product use, the quick-release assembly and the main rod are assembled by adopting clearance fit, namely, a fixing boss 1.10.1 is arranged inside the connecting end of the fixing sleeve 1.10, a fixing groove 2.1 is arranged on the end face of the main rod 2, and the fixing boss 1.10.1 and the fixing groove 2.1 are in clearance fit, so that the quick-release assembly can freely rotate on the main rod but cannot fall off. And the weight plate adopts a conventional integral structure, so that the eccentric phenomenon caused by an open structure is avoided.
According to the invention, the locking structures capable of being quickly locked and unlocked are designed on the two sides of the barbell bar, so that the weight plate can be quickly assembled and disassembled, and the locking bosses are arranged on the locking structures, so that the weight plate is prevented from falling off due to failure or misoperation of the spring in the use process. The invention can save the time for a user to adjust the weight plate, and can improve the use safety and comfort.
