Description

Technical Field

[0001] This utility model relates to the field of locking device manufacturing technology, and in particular to a locking device for a shaped block connecting screw. Background Technology

[0002] In current extrusion molding, due to the special nature of the profiles, some profiles need to be pulled out, and the upper plate of the shaping block needs to be removed from the water tank. When pulling, the shaping block is put back into the water tank. This operation will cause the connecting screws of the shaping block to fall out, and the connecting screws need to be reinstalled when pulling.

[0003] The variety of profiles can result in screws of varying lengths, which can easily lead to incorrect screw installation by fitters, thus prolonging the traction time and increasing the operator's workload. Therefore, reducing the traction time and the operator's workload is one of the key factors for the practicality of this device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a locking device for connecting screws of a shaping block. This device prevents the connecting screws from coming loose and falling off, and greatly improves the accuracy and efficiency of subsequent installation of the connecting screws.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A locking device for a connecting screw of a shaping block is disclosed. The shaping block includes a first shaping part and a second shaping part. The second shaping part has an installation hole through which the connecting screw passes. The connecting screw includes a columnar first connecting part and a second connecting part. The outer diameter of the second connecting part is smaller than that of the first connecting part, and the first connecting part and the second connecting part are arranged coaxially. A locking component is also provided inside the installation hole. The locking component extends into the installation hole and is located on the movement path of the first connecting part.

[0007] Preferably, the locking assembly includes a first locking part and a second locking part, and an elastic element is disposed between the first locking part and the second locking part.

[0008] Preferably, the first locking part and the second shaping part are detachably connected.

[0009] Preferably, a release block is fixed to the outer wall of the second connecting part. The release block is located near the first connecting part, and the locking component is controlled to retract during the movement of the second connecting part.

[0010] Preferably, the release block includes at least an arcuate surface and a straight surface, the arcuate surface being disposed along the circumferential surface of the second connecting portion, and the straight surface facing the locking assembly.

[0011] Preferably, the first end of the arc-shaped surface is flush with the second connecting portion.

[0012] Preferably, the second end of the arc-shaped surface is flush with or at least partially protrudes from the surface of the first connecting portion.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] By modifying the repositioning of the connecting screw, the connecting screw is positioned at the repositioning point, preventing it from disengaging from the locking assembly. However, it can move easily up and down at the repositioning point, thus achieving the screw's connection function while preventing it from falling off. This greatly improves the accuracy and efficiency of subsequent screw installation. Attached Figure Description

[0019] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0020] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0021] To address the problems mentioned in the background art, see Appendix Figure 1 - Appendix Figure 3 A locking device for connecting screws of a shaping block is disclosed. The shaping block includes a first shaping part 100 and a second shaping part 200. The second shaping part 200 has a mounting hole 210 through which a connecting screw 300 passes. The first shaping part 100 and the second shaping part 200 can be fixed to each other by the connecting screw 300 to form a relatively stable whole. There can be two mounting holes 210, which can lock and limit the first shaping part 100 and the second shaping part 200 from two far apart positions, and can ensure the locking and fixing of a long shaping block.

[0022] Specifically, the connecting screw 300 includes a columnar first connecting portion 310 and a second connecting portion 320. The outer diameter of the second connecting portion 320 is smaller than that of the first connecting portion 310. The first connecting portion 310 and the second connecting portion 320 are arranged coaxially. Compared with the first connecting portion 310, there is a gap around the second connecting portion 320. A locking component 400 is also provided inside the mounting hole 210. The locking component 400 extends into the mounting hole 210 and is located on the movement path of the first connecting portion 310.

[0023] By setting the locking component 400, the second connecting part 320 can pass through and move normally, while the first connecting part 310 can be locked and positioned. The first connecting part 310 can be locked and limited at the lower position to prevent the connecting screw 300 from coming out of the mounting hole 210.

[0024] With the above structural design, after the second connecting part 320 is unscrewed, the connecting screw 300 is positioned inside the mounting hole 210 under the limit of the locking component 400, which prevents the connecting screw 300 from coming off. At the same time, the second connecting part 320 here is relatively long and can move linearly along a certain length of space, which meets the needs of disassembling and installing the connecting screw 300.

[0025] Specifically, the locking assembly 400 includes a first locking part 410 and a second locking part 420. An elastic element is provided between the first locking part 410 and the second locking part 420. The elastic element can be selected as a spring. Under the action of the above structure, the second locking part 420 can abut against the surface of the second connecting part 320, which can further prevent the first connecting part 310 from moving out.

[0026] Meanwhile, under the action of the elastic element, the second locking part 420 here has a certain amount of room for movement, which can lock and limit the second connecting parts 320 of different sizes, thereby improving the adaptability of the overall structure.

[0027] Furthermore, the first locking part 410 is detachably connected to the second shaping part 200. An installation opening is provided on the side wall of the second shaping part 200. The first locking part 410 can be threadedly connected to the installation opening. It should be noted that the installation opening is preferably arranged perpendicular to the installation hole 210.

[0028] A release block 321 is fixed on the outer wall of the second connecting part 320. The release block 321 is located on the side close to the first connecting part 310. During the movement of the second connecting part 320, the locking component 400 is controlled to retract by the release block 321.

[0029] With the above structural design, it is not necessary to completely remove the locking component 400 during the process of completely removing the connecting screw 300. Moving the second connecting part 320 controls the release block 321 to move to the side of the locking component 400 to control the locking component 400 to retract, thereby removing the restriction of the locking component 400 on the first connecting part 310 and realizing the free removal of the connecting screw 300.

[0030] The release block 321 here includes at least an arc-shaped surface and a straight surface. The arc-shaped surface is arranged along the circumferential surface of the second connecting part 320, and the straight surface faces the locking component 400. By setting the arc-shaped surface, after the second connecting part 320 drives the first connecting part 310 to move to a predetermined position, the second connecting part 320 can be controlled to rotate around a predetermined angle, thereby controlling the locking component 400 to retract.

[0031] During the rotation of the second connecting part 320 around the axis, the thickness of the disengaging block 321 gradually increases. When the thickest part of the disengaging block 321 is opposite to the locking component 400, the locking component 400 is completely retracted into the mounting opening. At this time, the first connecting part 310 can move freely in the mounting hole 210 and be completely discharged.

[0032] Furthermore, the first end of the arc-shaped surface is flush with the second connecting portion 320; the second end of the arc-shaped surface is flush with or at least partially protrudes from the surface of the first connecting portion 310. Through the above arrangement, the first end of the arc-shaped surface can smoothly contact the locking component 400. At the same time, after rotating a predetermined angle, the second locking portion 420 can be flush with the surface of the disengaging block 321 and the first connecting portion 310. The restriction of the second locking portion 420 on the first connecting portion 310 is removed, and it can move freely.

[0033] The threaded end of the connecting screw 300 can be set to be tapered. As the connecting screw 300 moves inward, the tapered structure can guide the locking component 400, enabling the rapid assembly of the connecting screw 300 when the locking component 400 is installed in place.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
