Description

Technical Field

[0001] This utility model relates to the field of counterweight technology, and in particular to a balance counterweight structure. 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, the torque in the system is balanced, preventing tilting and excessive vibration, improving the stability of the system, and keeping it in a balanced state when subjected to external forces.

[0003] In order to better realize the function of balancing counterweight, a balancing counterweight structure is needed. The balancing counterweight structure is a device used to adjust the center of gravity of equipment and system. Its main function is to provide the necessary weight to achieve balance.

[0004] The existing counterweight structure has the following drawbacks:

[0005] Currently, most counterweights on the market are one-piece designs. To ensure the fit between the counterweight and the equipment to which it needs to be added, the shape of the counterweight must be selected based on the shape of the equipment. This greatly increases the workload and time required, and affects work efficiency.

[0006] Therefore, we propose a counterweight structure to address the problems mentioned above. Utility Model Content

[0007] The counterweight body has a connecting groove, in which a connecting block and a connecting rod are fixed. A second connecting rod, linked to the rotating shaft, causes the connecting rod to rotate synchronously when the counterweight is rotated. A rotating tube is used to connect the first connecting rods of multiple counterweights in series, achieving rotational connection through insertion until the required weight is achieved. For circular equipment, the counterweight naturally adapts to its shape. A flathead screwdriver is used in conjunction with the rotating shaft for fixation, maintaining rotational flexibility and adapting to different equipment needs. If precise adjustment of the counterweight is required, a weight-reducing hole is provided on the inner side of the counterweight body. A weight-reducing block is slidably connected. Through a limit slider and spring mechanism, a needle-like object is used to push the weight-reducing block, compressing it and causing it to slide into the limit hole and then fall down. This operation is repeated until the precise weight is achieved. This simplifies the process of selecting counterweights, reduces working time, improves work efficiency, and also enables precise counterweight control, thus solving the problems mentioned in the background technology.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a counterweight structure, comprising a counterweight body, a plurality of weight-reducing holes on the top of the counterweight body, a connecting groove on the front side of the counterweight body, a connecting block fixedly connected to the inner side of the connecting groove, a first connecting rod fixedly connected to the outer side of the connecting block, a rotating tube fixedly connected to the outer side of the counterweight body, a first fixing hole on the inner side of the rotating tube, a rotating groove on the front side of the counterweight body, and a weight-reducing mechanism provided in the weight-reducing holes.

[0009] Preferably, the weight reduction mechanism includes a weight reduction block, which is slidably connected to the inside of the weight reduction hole. A limit hole is formed inside the weight reduction block, and a spring is fixedly connected inside the limit hole. The other end of the spring is fixedly connected to a limit slider, and the limit slider is slidably connected to the limit hole.

[0010] Preferably, the outer side of the first connecting rod engages with the inner side of the rotating tube of another counterweight body, and the first connecting rod is rotatably connected to the rotating tube.

[0011] Preferably, an overflow groove is provided on the outer side of the counterweight body, the other end of the first connecting rod is rotatably connected to a rotating shaft, the other end of the rotating shaft is rotatably connected to a second connecting rod, and the rotating shaft and the second connecting rod are rotatably connected to the inside of the rotating tube in sequence.

[0012] Preferably, a second fixing hole is provided on the inner side of the rotating shaft, and a fixing screw is threaded into the second fixing hole. A slot is provided on the top of the fixing screw.

[0013] Preferably, the second fixing hole and the first fixing hole are holes of the same size and position, and both are threaded inside, and are fixed by threaded connection with the fixing screw.

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

[0015] 1. In this utility model, the main body of the counterweight has a connecting groove, in which a connecting block and a first connecting rod are fixed. The connecting rod is linked with the rotating shaft to form a second connecting rod. When the counterweight is rotated, the connecting rod rotates accordingly. The outer rotating tube is used for connecting multiple blocks. Rotational connection is achieved by insertion until the required weight is reached. For circular equipment, the connected counterweight naturally conforms to the shape when placed on the equipment. It is fixed by the rotating shaft and a flathead screwdriver without affecting rotational deformation. It adapts to different equipment, simplifies the selection of counterweight shape, and improves work efficiency.

[0016] 2. In this utility model, when more precise counterweight adjustment is required, the inner side of the counterweight block body is provided with multiple weight reduction holes, and a weight reduction block is slidably connected in the hole. The weight reduction block is connected to the weight reduction hole through a limiting slider with internal telescopic sliding limit. The weight reduction block to be removed is pushed with a needle-like object. The limiting slider is compressed under the action of the spring and slides into the limiting hole on the weight reduction block, and then slides down. The operation is repeated until the ideal weight is achieved, so as to realize precise counterweight control. Attached Figure Description

[0022] 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.

[0023] 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.

[0024] Example 1, as shown in the attached document Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a counterweight structure includes a counterweight body 1, a plurality of weight-reducing holes 3 on the top of the counterweight body 1, a connecting groove 4 on the front side of the counterweight body 1, a connecting block 8 fixedly connected to the inner side of the connecting groove 4, a first connecting rod 5 fixedly connected to the outer side of the connecting block 8, a rotating tube 7 fixedly connected to the outer side of the counterweight body 1, a first fixing hole 9 on the inner side of the rotating tube 7, a rotating groove 6 on the front side of the counterweight body 1, and a weight-reducing mechanism 2 provided in the weight-reducing holes 3.

[0025] The overall effect of Embodiment 1 is as follows: the connecting groove 4 is used to place the connecting block 8, making the whole square and easy to use. The connecting block 8 is used to connect the counterweight body 1 and the first connecting rod 5. Since the first connecting rod 5 is fixed on the connecting block 8, and the first connecting rod 5 is linked to the second connecting rod 14 by means of the rotational connection of the rotating shaft 15, the first connecting rod 5 will rotate synchronously when the counterweight body 1 is rotated. Since the rotating tube 7 is fixed on the outside of the counterweight body 1, when multiple counterweights need to be used at the same time, the first connecting rod 5 of one counterweight and its rotating shaft 15 and second connecting rod 14 are first inserted into the rotating tube 7 of another counterweight. At this time, the two counterweights are rotatedly connected to the rotating tube 7 through the first connecting rod 5, thereby realizing the combined use of multiple counterweights to meet different counterweight requirements, improving the flexibility and adaptability of the device in practical applications, and better coping with diverse working scenarios and conditions, providing stable and adjustable counterweight support for related operations.

[0026] Example 2, as Figure 2 and Figure 3 As shown, the weight reduction mechanism 2 includes a weight reduction block 201, which is slidably connected to the inside of the weight reduction hole 3. A limit hole 202 is opened inside the weight reduction block 201, and a spring 203 is fixedly connected inside the limit hole 202. The other end of the spring 203 is fixedly connected to a limit slider 204, and the limit slider 204 is slidably connected to the limit hole 202.

[0027] The effect achieved by the entire embodiment 2 is as follows: the limiting hole 202 is used to place the weight reduction block 201 and the spring 203. When the limiting slider 204 is pushed, it squeezes the spring 203 by pressing against the weight reduction groove 3, so that the limiting slider 204 and the spring 203 retract into the weight reduction groove 3, making the weight reduction work more convenient and smooth.

[0028] Example 3, as Figure 1 and Figure 2As shown, the outer side of the first connecting rod 5 engages with the inner side of the rotating tube 7 of the other counterweight body 1. The first connecting rod 5 is rotatably connected to the rotating tube 7. An overflow groove 12 is provided on the outer side of the counterweight body 1. The other end of the first connecting rod 5 is rotatably connected to a rotating shaft 15. The other end of the rotating shaft 15 is rotatably connected to a second connecting rod 14. The rotating shaft 15 and the second connecting rod 14 are rotatably connected to the inside of the rotating tube 7 in sequence. A second fixing hole 13 is provided on the inner side of the rotating shaft 15. A fixing screw 10 is threaded into the second fixing hole 13. A slot 11 is provided on the top of the fixing screw 10. The second fixing hole 13 and the first fixing hole 9 are holes of the same size and position, and both are threaded inside. They are fixed by being threadedly connected to the fixing screw 10.

[0029] The effect achieved by the entire embodiment 3 is as follows: the rotating shaft 15 and the rotating tube 7 ensure that the two counterweights can be fixed to each other without affecting their mutual rotation and shape change. The fixing screw 10 is used to fix the second fixing hole 13 and the first fixing hole 9, thereby fixing the two counterweights. The slot 11 can better rotate the fixing screw 10.

[0030] The working principle of the entire device is as follows: The counterweight body 1 has a connecting groove 4, within which a connecting block 8 is fixed. A first connecting rod 5 is fixed to the connecting block 8. The first connecting rod 5 is rotatably connected to a second connecting rod 14 via a rotating shaft 15. Therefore, when the counterweight body 1 is rotated, the first connecting rod 5 also rotates. Since a rotating tube 7 is fixed to the outside of the counterweight body 1, when multiple counterweights need to be used simultaneously, the first connecting rod 5 of one counterweight, along with its rotating shaft 15 and second connecting rod 14, is inserted into the rotating tube 7 of another counterweight. At this time, the two counterweights are rotatably connected via the first connecting rod 5 and the rotating tube 7. This process continues until the desired counterweight weight is achieved. When the device requiring the counterweight is circular, the already connected counterweight is placed on the device to be bonded. On the surface, the connected counterweight naturally takes on the required shape. Then, rotate the rotating shaft 15 so that the second fixing hole 13 on the rotating shaft 15 coincides with the first fixing hole 9 on the rotating tube 7. Then, use a flathead screwdriver to insert from the first fixing hole 9 into the fixing screw 10 in the second fixing hole 13. Since the fixing screw 10 has a slot 11, turn the fixing screw 10 to fix the rotating tube 7 and the rotating shaft 15 by threaded connection with the fixing screw 10. Since the rotating shaft 15 rotates with the first connecting rod 5, when the two counterweights are fixed, it does not affect their mutual rotation and shape change. This allows the shape of the counterweights to be changed according to the shape of the required counterweight equipment, reducing the need to select different shapes of counterweights for different equipment, reducing working time, and improving work efficiency.

[0031] When more precise counterweighting is required, multiple weight-reducing holes 3 are provided on the inner side of the main body 1 of the counterweight block. A weight-reducing block 201 is slidably connected in the weight-reducing hole 3. The weight-reducing block 201 is slidably connected to the weight-reducing hole 3 through the limiting slider 204 inside it. Therefore, by pressing any needle-like object against the weight-reducing block 201 to be removed and pushing it forcefully, the limiting slider 204 on the weight-reducing block 201 and the spring 203 fixed to it will compress themselves and the spring 203 into the limiting hole 202 on the weight-reducing block 201. At this time, the limiting slider 204 will slide down. Repeat the above operation until the required weight is reached, thereby achieving precise control of the required weight of the counterweight.

[0032] 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.
