Description

Technical Field

[0001] This utility model relates to the field of counterweight technology, and in particular to a ring-shaped combined counterweight. Background Technology

[0002] In mechanical equipment, counterweights are used to balance the weight of rotating or moving parts, reduce vibration and wear, improve mechanical efficiency and service life. By adding weight, they balance the torque in the system, prevent tilting and excessive vibration, improve the stability of the system, and keep it in a balanced state when subjected to external forces. In some cases, counterweights can be used to control the moving speed and response of the equipment.

[0003] To better realize the counterweight function, a ring-shaped combination counterweight is needed. The counterweight is a specially designed weight used to provide balance and stability in various machines, equipment and structures.

[0004] The existing ring-shaped combined counterweight has the following shortcomings:

[0005] Currently, all the ring-shaped combination counterweights on the market are assembled by inserting rods through the central hole. This is unstable, and the combined weight can easily reach its limit due to the length of the rods. When a larger weight is needed, it cannot be used.

[0006] Therefore, we propose a ring-shaped combined counterweight to solve the problems mentioned above. Utility Model Content

[0007] When assembling the ring-shaped combination counterweight, first connect the bottom of one counterweight to the top of another using a sliding engagement mechanism. Then, the elastic limit slider automatically pops out, completing the initial fixation of the two counterweights. Use a flathead screwdriver to rotate the threaded pin, pushing it out of the telescopic tube and screwing it into the threaded tube of the lower counterweight. This process can be repeated multiple times to achieve continuous assembly. If the required counterweight is less than the weight of a single counterweight, the screwing block can be rotated to separate the threaded connection between the weight-reducing column and the weight-reducing chamber, thereby reducing the total weight of the counterweight. This overcomes the limitations of traditional insert rod combinations and achieves precise counterweight adjustment, thus solving the problems mentioned in the background technology.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a ring-shaped combined counterweight, comprising a counterweight body, two connecting holes on the inner side of the counterweight body, a shock-absorbing column fixedly connected to the inner side of the connecting holes, a threaded pin slidably connected to the inner side of the shock-absorbing column, a rotating groove on the outer side of the threaded pin, a first rotating ring rotatably connected to the inner side of the rotating groove, a spring fixedly connected to the outer side of the first rotating ring, a second rotating ring fixedly connected to the top of the spring, a telescopic tube rotatably connected to the outer side of the second rotating ring, a threaded tube fixedly connected to the top of the telescopic tube, and a weight-reducing mechanism provided inside the counterweight body.

[0009] Preferably, the device includes a shock-absorbing block mechanism, which includes a weight-reducing chamber located on the outside of the counterweight block body. The weight-reducing chamber is threadedly connected to the inside of a threaded strip, and a weight-reducing column is fixedly connected to the inside of the threaded strip. A turning block is fixedly connected to the outside of the weight-reducing column.

[0010] Preferably, the outer side of the counterweight body has a flat surface, the top of the counterweight body has a slider groove, and the bottom of the inner side of the slider groove is fixedly connected to an elastic limiting slider.

[0011] Preferably, a movable groove is provided on the front side of the counterweight body, and a pull bolt is provided on the inner side of the movable groove.

[0012] Preferably, a pull ring is fixedly connected to the outer side of the pull bolt, and multiple anti-slip rings are fixedly connected to the outer side of the pull ring.

[0013] Preferably, the top of the counterweight body is provided with a T-shaped slide rail, and the bottom of the counterweight body is provided with a T-shaped slide groove, wherein the T-shaped slide rail and the T-shaped slide groove are slidably engaged.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, when using the combined ring counterweights, firstly, the bottom of one ring counterweight is slidably engaged with the top of another ring counterweight. The elastic limit slider automatically springs up to achieve the limit, and the two counterweights are initially fixed. Then, a flathead screwdriver is used to rotate the threaded nail, which is pushed out of the telescopic tube and threadedly connected to the threaded tube of the lower counterweight. Repeating this step can achieve infinite combination of counterweights, avoiding the limitation problem of the traditional stick insertion hole combination method.

[0016] 2. In this utility model, when the required counterweight is lower than the weight of a single ring-shaped counterweight block, the weight-reducing column is disengaged from the weight-reducing chamber by turning the turning block, thereby reducing the overall weight of the counterweight block and achieving precise and controllable counterweight adjustment.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention can also be implemented in other ways than those described herein, and therefore the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1, as shown in the attached document Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, a ring-shaped combined counterweight includes a counterweight body 1. Two connecting holes 17 are opened on the inner side of the counterweight body 1. A shock-absorbing column 3 is fixedly connected to the inner side of the connecting holes 17. A threaded pin 4 is slidably connected to the inner side of the shock-absorbing column 3. A rotating groove 5 is opened on the outer side of the threaded pin 4. A first rotating ring 6 is rotatably connected to the inner side of the rotating groove 5. A spring 8 is fixedly connected to the outer side of the first rotating ring 6. A second rotating ring 18 is fixedly connected to the top of the spring 8. A telescopic tube 9 is rotatably connected to the outer side of the second rotating ring 18. A threaded tube 10 is fixedly connected to the top of the telescopic tube 9. The outer side of the threaded tube 10 is fixedly connected to the bottom of the inner side of the shock-absorbing column 3. A weight-reducing mechanism 2 is provided inside the counterweight body 1.

[0026] The effect achieved by the entire embodiment 1 is as follows: the shock-absorbing column 3 is used to reduce vibration damage to the internal mechanism when the annular combined counterweight is under heavy use. A threaded tube 10 is fixed inside the shock-absorbing column 3. The threaded tube 10 can be threadedly fixed with the threaded nail 4. A telescopic tube 9 is fixed at the bottom of the threaded tube 10. A second rotating ring 18 rotates inside the telescopic tube 9. The second rotating ring 18 is fixed to the first rotating ring 6 by a spring 8. The first rotating ring 6 rotates with the threaded nail 4 through the rotating groove 5. The spring 8 is used to retract the threaded nail 4 into the shock-absorbing column 3. The threaded nail 4 is threadedly connected to the threaded tube 10 below.

[0027] Example 2, as Figure 2 and Figure 3 As shown, the damping block mechanism 2 includes a weight reduction chamber 201, which is located on the outside of the counterweight block body 1. A threaded bar 203 is threadedly connected to the inside of the weight reduction chamber 201. A weight reduction column 202 is fixedly connected to the inside of the threaded bar 203. A screwing block 204 is fixedly connected to the outside of the weight reduction column 202.

[0028] The overall effect of embodiment 2 is as follows: the weight reduction chamber 201 is used to place the weight reduction column 202, reducing the wear of the weight reduction column 202 and ensuring the accuracy of the added weight. The weight reduction column 202 is used to accurately control the added weight, making this annular combination counterweight block more effective. The threaded strip 203 connects the weight reduction column 202 to the weight reduction chamber 201 conveniently, making it easy to disassemble and assemble. The screwing block 204 facilitates the rotation of the weight reduction column 202.

[0029] Example 3, as Figure 1 and Figure 2As shown, a flat surface is provided on the outer side of the counterweight body 1, and a slider groove 11 is provided on the top of the counterweight body 1. An elastic limiting slider 12 is fixedly connected to the bottom of the inner side of the slider groove 11. A moving groove 13 is provided on the front side of the counterweight body 1. A pull bolt 14 is provided on the inner side of the moving groove 13. A pull ring 15 is fixedly connected to the outer side of the pull bolt 14. Multiple anti-slip rings 16 are fixedly connected to the outer side of the pull ring 15. A T-shaped slide rail is provided on the top of the counterweight body 1, and a T-shaped slide groove is provided on the bottom of the counterweight body 1. The T-shaped slide rail and the T-shaped slide groove slide and engage.

[0030] The overall effect of embodiment 3 is as follows: the slider groove 11 is used to place the elastic limiting slider 12. The elastic limiting slider 12 uses its own elasticity to stretch and extend, so that the annular combination counterweight blocks can be initially engaged when they are combined. The T-shaped slide rail at the top and the T-shaped slide groove at the bottom of the counterweight block body 1 make the combination docking more precise and controllable, which is conducive to the remaining combination fixing work. The pull bolt 14 is placed in the moving groove 13, which makes it easier to move the annular combination counterweight blocks. The pull ring 15 is conducive to pulling up the pull bolt 14. The anti-slip ring 16 plays an anti-slip role.

[0031] The working principle of the entire device is as follows: When the ring-shaped counterweights need to be used in combination, the bottom of one ring-shaped counterweight is first slidably engaged with the top of another ring-shaped counterweight. When the two ring-shaped counterweights are engaged, the elastic limit slider 12 springs up and engages in a limited position. At this time, the two ring-shaped counterweights overlap and are initially fixed in combination. Because a shock-absorbing column 3 is fixed inside the counterweight body 1, and a threaded tube 10 is fixed inside the shock-absorbing column 3, and a telescopic tube 9 is fixed at the bottom of the threaded tube 10, a second rotating ring 18 rotates inside the telescopic tube 9. The second rotating ring 18 is fixed to the first rotating ring 6 by a spring 8. The first rotating ring 6 rotates through the rotating groove 5 and the threaded nail 4. A flathead screwdriver is inserted into the hole inside the threaded tube 10, passes through the telescopic tube 9, and then is inserted into the screwing groove 7 on the threaded nail 4. At this time, the flathead screwdriver is pressed down to push the threaded nail 4 out of the telescopic tube 9 until it reaches the inside of the threaded tube 10 on the lower annular combination counterweight block. Then, the flathead screwdriver is turned to make the threaded nail 4 threadedly connected to the lower threaded tube 10. This process is repeated to achieve unlimited combination and counterweight of the annular combination counterweight block, overcoming the shortcoming of relying on inserting a stick into its own internal hole to achieve the upper limit of combination.

[0032] When the required weight of the counterweight is lower than the overall weight of a single ring-shaped counterweight block, the rotating block 204 is fixed with a weight-reducing column 202, which is fixed with a threaded strip 203 and connected to the weight-reducing chamber 201 opened on the inner side of the counterweight block body 1 through the threaded strip 203. At this time, rotating the rotating block 204 will cause the weight-reducing column 202 on it to rotate and disconnect from the weight-reducing chamber 201, so that the overall ring-shaped counterweight block can reduce part of its weight. This solves the problem of the shortcoming when the required weight of the counterweight is lower than the overall weight of a single ring-shaped counterweight block, making the weight of the counterweight more precise and controllable.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
