Description

Dumbbells with quick weight adjustments

The invention relates to the technical field of a weight-adjustable dumbbell structure, especially a kind of dumbbell that can quickly adjust the weight plate to achieve the purpose of conveniently adjusting the weight.

A known dumbbell structure with adjustable weight, as shown in Taiwan Publication No. M627768 "Adjustable Weight Dumbbell" patent, which mainly uses two clamping shafts to pass through multiple weight plates respectively and then tighten the screws to lock them on one handle. to achieve the purpose of combining and fixing the plurality of weight plates at the two ends of the handle to form a dumbbell for use. Then the two clamping shafts can be screwed out of the two ends of the handle to facilitate the removal of the weight sheet or the replacement of weight sheets of different weights, and then the two clamping shafts can be screwed tightly to adjust the dumbbell. purpose of weight.

Therefore, when adjusting the weight of this known dumbbell structure that can adjust the weight, the two clamping shafts need to be rotated for multiple turns to release the weight sheets for removing or replacing the weight sheets, and when the weight sheets are installed After the corresponding weight sheets, it is necessary to rotate the two clamping shafts in reverse for multiple turns before tightening and restricting these weight sheets, so that the multiple weight sheets can be combined and fixed on the two ends of the handle, so it will cost a lot of money to adjust. It takes a lot of time to rotate the two clamping shafts, which results in time-consuming and labor-intensive shortcomings.

In view of this, the author of this work developed and designed this creation based on the above-mentioned problems, in-depth conception, and active research and improvement.

The main purpose of this creation is to solve the problem of conventional weight-adjustable dumbbells. When adjusting the weight, the two clamping shafts need to be rotated multiple times to unscrew and release or tighten the weight plates, which causes time-consuming weight adjustment. The problem of effort and so on.

The dumbbell that can quickly adjust the counterweight described in this creation includes a grip, multiple counterweight plates, two locking parts and two buckle modules. Wherein, the handle includes a tube body. The plurality of counterweight plates can be arranged side by side at the two ends of the handle respectively, and each of the plurality of counterweight plates has a combination hole through them. The two locking parts respectively include a screw rod and a head, and the screw rods of the two locking parts can be inserted into the two ends of the tube body through the coupling holes of the corresponding plurality of weight plates, And the head can be made to lean against the outer surface of the outermost weight plate. The two buckle modules are respectively combined with the two ends of the pipe body, and can be driven into a state of being screwed with the two locking pieces, and can be driven into a state of releasing the two screw rods.

The dumbbell that can quickly adjust the counterweight provided by this creation can form a quick-release structure with the two buckle modules at both ends of the handle and the two lock pieces, so that the two lock pieces can be quickly pulled out Or insert the two ends of the handle, especially after the two locking parts are inserted into the two ends of the handle, it only needs to rotate less than one turn to achieve the effect of fine-tuning and locking, so the multiple counterweights can be replaced quickly pieces, in order to achieve the purpose of quick and convenient weight adjustment.

The plurality of counterweight plates 30 can be set to various weights respectively, and can be arranged side by side on the outsides of the two abutment plates 14 respectively. Each counterweight plate 30 has a combination hole 31 through, and the two opposite sides are respectively There is a corresponding positioning block 32 and a positioning groove 33, the positioning block 32 can be embedded in the corresponding positioning groove 141 of the abutment plate 14 or embedded in the positioning of another weight plate 30 In the slot 33 , the positioning slot 33 can be used for the positioning block 32 of another weight plate 30 to be embedded.

The two locking pieces 40 can respectively combine and fix the plurality of counterweight plates 30 on the outside of the two abutment plates 14, each locking piece 40 includes a screw rod 41 and a head 42, and the screw rod 41 can be worn Through the combination holes 31 of the weight plates 30, the through holes 140 of the abutment plate 14 on the corresponding side and the through holes 130 of the shell cover 13 on the corresponding side, they are inserted and combined in one end of the tube body 11, So that the head 42 can abut against the outer surface of the outermost weight plate 30 . Wherein, when the buckle 21 is at the buckle position, the external thread of the screw rod 41 can be screwed with the buckle projection 212 of the buckle 21, and when the buckle 21 is at the release position, the The locking protrusion 212 of the locking member 21 is separated from the external thread of the screw rod 41 .

Please refer to Fig. 4 to Fig. 6, which means that when the driver 22 is pulled upwards, one end will push the buckle 21 below to swing from the buckle position to the release position. The plurality of buckle projections 212 of the fastener 21 will be disengaged The outer thread of the screw rod 41 of the locking member 40, so that the locking member 40 can be quickly drawn out to release the plurality of weight plates 30, and then for conveniently removing or replacing the plurality of weight plates 30, and in the When the buckle 21 is at the release position, the screw 41 of the lock 40 can also quickly pass through the replaced plurality of weight plates 30 and be inserted into one end of the tube body 11, and then the The driver 22 is pulled downwards, so that the elastic force of the restoring elastic body 23 bounces the buckle 21 from the release position back to the buckle position, and then the plurality of buckle protrusions 212 of the buckle 21 are engaged. Buckle in the external thread of the screw rod 41 of the locking member 40 to form a screwed state, and then fine-tune and tighten the locking member 40 to complete the weight adjustment of the dumbbell, so it is very fast to adjust the weight convenient.

In this creation, the two abutment plates 14 are hexagonal, the shape of the two positioning grooves 141 is a smaller hexagon corresponding to the two abutment plates 14, and the shape of the plurality of counterweight plates 30 is opposite Should two abut against plate 14 and be hexagonal, this positioning block 32 is corresponding to this positioning groove 141 and is hexagonal, and this positioning groove 33 is corresponding to this positioning block 32 and is hexagonal, thereby can make The plurality of counterweight plates 30 can be assembled in corresponding alignment directions. Certainly, in this creation, the two abutment plates 14, the two positioning grooves 141, the plurality of weight plates 30, the positioning blocks 32 and the positioning grooves 33 can be other corresponding polygons, and this is no longer provided separately. Let's go into details one by one.

The dumbbell that can quickly adjust the counterweight provided by this creation can form a quick release structure by the two buckle modules 20 at the two ends of the handle 10 and the two lock parts 40, so that the two lock parts 40 can be quickly withdrawn or inserted into the two ends of the handle 10, especially after the two lock parts 40 are inserted into the two ends of the handle 10, it only needs to rotate less than one circle to achieve the effect of fine-tuning locking, so it is convenient The plurality of weight stacks 30 can be quickly replaced, In order to achieve the purpose of fast and convenient weight adjustment.

Please refer to Fig. 7, which is another embodiment of the above-mentioned dumbbell that can quickly adjust the weight. The two shell covers 13 are screwed on the two shells 12 . Moreover, the two locking members 40 can also pass through the plurality of weight plates 50 removed from the old dumbbells, so as to be combined with the two ends of the handle 10, so that various shapes and specifications of the old dumbbells can be effectively utilized. The plurality of weight stacks 50.

To sum up, since this creation has the above-mentioned advantages and practical value, and no similar products have been published among similar products, it has met the requirements for application for a new model patent, and the application should be filed in accordance with the law.
