Description

Technical Field

[0001] This utility model relates to the field of plastic chuck technology, and in particular to a plastic chuck with adjustable length. Background Technology

[0002] The development of plastic processing technology has also provided technical support for the production of plastic chucks. Advanced injection molding technology can manufacture plastic parts with complex shapes and high precision. By optimizing mold design and injection process parameters, the dimensional accuracy and quality stability of plastic chucks can be ensured. Therefore, a plastic chuck with adjustable length is needed.

[0003] Adjustable-length plastic chucks are made primarily of plastic and utilize a threaded rod and nut in conjunction with a telescopic adjustment mechanism. Rotating the screw moves the jaws axially or extends / contracts the sliding portion, which is then fixed by a positioning device, allowing for flexible adjustment of the chuck's clamping length over a wide range. Currently, adjustable-length plastic chucks require rotating an adjustment rod to move the jaws or slider, especially when significant length adjustments are needed, requiring multiple rotations and consuming considerable time. This is unsuitable for scenarios requiring high operational efficiency and frequent, rapid changes in chuck length. Existing solutions combine coarse and fine threads. For rapid, large adjustments, the coarse thread is used, achieving a larger length change with fewer rotations. When precise adjustments are needed, the fine thread is switched to ensure high accuracy. However, switching from coarse to fine threads requires an additional fork and conversion knob, increasing operational complexity. Operators need time to familiarize themselves with the switching process, and frequent switching can easily lead to misoperation, affecting adjustment efficiency and accuracy. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a plastic chuck with adjustable length, which aims to improve the problem that when switching from coarse to fine threads, additional shift forks and conversion knobs are required, increasing the complexity of operation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable-length plastic chuck, comprising a roller and two connecting plates. Connecting plates are connected to the left and right sides of the outer wall of the roller. A groove is formed in the middle of the outer wall of each of the two connecting plates.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of an adjustable-length plastic chuck, comprising a roller 1 and two connecting plates 3. Connecting plates 3 are evenly connected to the left and right sides of the outer wall of the roller 1. When length adjustment is required, the handle 23 is gripped, and a pulling or pushing force is applied to the two connecting plates 3. Since the rotating plate 9 rotates within the connecting groove 8, and the cross rod 6 is rotatably connected to the rotating plate 9, the angle between the cross rod 6 and the rotating plate 9 changes under the force, thus changing the distance between the two connecting plates 3. This achieves the adjustment of the distance between the connecting plates 3 connected to both ends of the roller 1, i.e., the adjustment of the entire chuck length. A groove 22 is provided in the middle of the outer wall of each of the two connecting plates 3, and a handle 23 is fixedly connected to the inner wall of each of the two grooves 22. A connecting post 4 is fixedly connected to the left side of the outer wall of the right connecting plate 3. A baffle 5 is fixedly connected to the left end of the inner wall of the connecting column 4. The connecting column 4 provides a fixed support point for the cross rod 6. The baffle 5 inside ensures the stability of the cross rod 6 installation. The cross rod 6 is fixedly connected to the middle of the left side of the outer wall of the baffle 5. The connecting column 7 is fixedly connected to the right side of the outer wall of the left connecting plate 3. The connecting groove 8 of the connecting column 7 provides rotation space for the rotating plate 9 and also limits the range of motion of the rotating plate 9, ensuring that the rotating plate 9 will not detach from the connecting groove 8 during the adjustment process, thereby maintaining the stability of the entire structure during the length adjustment process. The connecting groove 8 is opened at the right end of the inner wall of the connecting column 7. The rotating plate 9 is rotatably connected to the front side of the inner wall of the connecting groove 8. The outer wall of the rotating plate 9 is rotatably connected to the cross rod 6. The outer walls of the two connecting plates 3 are provided with fixing mechanisms 2, which are used to fix the devices on the equipment.

[0032] Reference Figure 1 , Figure 4 and Figure 5 The fixing mechanism 2 includes two sliding blocks 202, which are disposed on the inner wall of the connecting plate 3. The outer walls of the two connecting plates 3 are provided with grooves 201, and the inner walls of the two grooves 201 are slidably connected to the sliding blocks 202. The two sliding blocks 202 are disposed on the inner wall of the connecting plate 3 and can slide within the grooves 201 on the outer wall of the connecting plate 3, so that the sliding blocks 202 can move around the grooves 201. The front side of the outer wall of the two sliding blocks 202 is provided with mounting holes 203. The mounting holes 203 on the sliding blocks 202 are used to allow one end of the winding device to be inserted into the mounting holes 203 when the device needs to be wound, and to press the pressing block 205 to fix it and prevent it from falling off. The front and rear sides of the top of the two sliding blocks 202 are connected to the connecting post 3 204, and the top of the two connecting post 3 204 is slidably connected to the pressing block 205.

[0033] Reference Figure 1 , Figure 2 and Figure 3Limiting grooves 10 are provided on the upper and lower sides of the outer wall of the left connecting column 2 7. Limiting blocks 11 are fixedly connected to the upper and lower sides of the left end of the inner wall of roller 1. The outer walls of the two limiting blocks 11 are engaged with the limiting grooves 10. Limiting blocks 11 are provided on the upper and lower sides of the left end of the inner wall of roller 1. Limiting grooves 10 are provided on the upper and lower sides of the outer wall of connecting column 2 7. When roller 1 is installed, the limiting blocks 11 slide into the limiting grooves 10 and finally achieve engagement. Connecting blocks 12 are fixedly connected to the upper and lower sides of the middle part of the inner wall of the right connecting column 1 4. The inner walls of the two connecting blocks 12 are fixed. A spring 13 is connected, and the other end of the two springs 13 is fixedly connected to the left side of the outer wall of the baffle 5. When the roller 1 needs to be extended, the pushing force of the spring 13 can make it easy for the operator to pull. Multiple connecting holes 14 are opened on both the left and right ends of the roller 1. Multiple connecting blocks 15 are fixedly connected to the adjacent side of the two connecting plates 3. The outer wall of the multiple connecting blocks 15 is engaged with the roller 1, so that the roller 1 and the connecting plate 3 are relatively fixed in the circumferential direction, ensuring that the roller 1 can rotate together with the connecting plate 3.

[0034] Reference Figure 2 , Figure 3 and Figure 4 Multiple connection holes 16 are provided around the outer walls of the two connecting plates 3. Connecting blocks 17 are fixedly connected to the inner walls of the multiple connection holes 16. When this device needs to be installed on a fixed bracket or used in conjunction with other mechanical structures, the connecting parts of the external equipment can be docked with these connecting blocks 17. Protective rings 18 are fixedly connected to the outer walls of the two connecting plates 3. Multiple screws 19 are threaded around the outer walls of the two protective rings 18. The screws 19 are threaded to the outer walls of the connecting plates 3. The protective rings 18 serve to protect the connecting plates 3 and prevent damage to the connecting plates 3 from external collisions, friction or other factors. A connecting groove 20 is provided in the middle of the outer wall of the roller 1. A partition plate 21 is fixedly connected to the inner wall of the connecting groove 20. The connecting groove 20 is used to install some auxiliary components related to cable collection or sorting.

[0035] Working principle: When the length of the plastic chuck needs to be adjusted, the operator holds the handle 23 located in the groove 22 in the middle of the outer wall of the two connecting plates 3. Through the handle 23, a pulling or pushing force is applied to the two connecting plates 3, thereby initiating the length adjustment operation. The two connecting plates 3 are connected by connecting post 1 4 and connecting post 2 7, cross rod 6 and rotating plate 9 respectively. A baffle 5 is fixedly connected to the left end of the inner wall of connecting post 1 4 on the right connecting plate 3. The cross rod 6 is fixedly connected to the middle of the left side of the outer wall of the baffle 5. The rotating plate 9 is rotatably connected to the connecting groove 1 8 opened at the right end of the inner wall of connecting post 2 7 on the left connecting plate 3. The outer wall of the rotating plate 9 is rotatably connected to the cross rod 6. During the process of applying external force to the connecting plates 3, since the rotating plate 9 can rotate freely in the connecting groove 1 8 and forms a rotatable connection with the cross rod 6, the relative angle between the cross rod 6 and the rotating plate 9 will change accordingly under the action of pulling or pushing force. This change in the angle between the cross rod 6 and the rotating plate 9 will change the distance between the two connecting plates 3.

[0036] Two sliding blocks 202 are set on the inner wall of the connecting plate 3 and form a sliding connection with the groove 201 opened on the outer wall of the connecting plate 3, so that the sliding blocks 202 can move along the groove 201. The front side of the outer wall of the sliding block 202 is provided with a mounting hole 203. When winding cables, one end of the winding device can be inserted into the mounting hole 203 to establish a connection with the sliding block 202. This allows the winding device to be relatively fixed on the entire chuck structure by relying on the sliding block 202. The top front and rear sides of each sliding block 202 are connected to the connecting post 3 204, and the pressing block 205 is slidably connected to the top of the connecting post 3 204. After inserting one end of the winding device into the mounting hole 203, it needs to be fixed to prevent it from falling out of the mounting hole 203 during use.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
