Description

Wire guide locking device Technical Field

[0001] This utility model relates to the field of steel cord production technology, and more specifically to a wire guide frame locking device. Background Technology

[0002] Electroplated steel cord is a surface treatment method that forms an alloy layer on the metal surface using an electrolyte solution. This improves the metal surface's corrosion resistance, thermal shock resistance, oxidation resistance, mechanical strength, and conductivity, extending its service life. It can also be used to enhance surface appearance and wear resistance.

[0003] In the electroplating process of steel cord, the guide roller and the wire stop frame must be made of nylon material according to process requirements. The function of the wire stop frame is to cooperate with the guide roller to limit the steel wire passing through the guide roller, so as to prevent the steel wire from falling off the groove on the surface of the guide roller. As shown in Figure 1, the wire stop frame in the prior art includes a nylon frame body 03, a rod body 02 and a wire stop spring 01. The rod body 02 is inserted into the blind hole at the top of the nylon frame body 03 and is fixed and locked by screws 04.

[0004] It should be understood that during the wire feeding process, the tension of the wire on the surface of the wire guide wheel will change due to the change in the feeding speed. After the wire stop spring 01 is stressed, the rod body 02 is stressed and driven around the axis of the blind hole, causing the screw 04 to loosen. Due to the low strength of the nylon frame 03, the screw 04 and the nylon frame 03 will slip, causing loosening. Summary of the Invention

[0005] To address the technical problems existing in the wire guide frame in the prior art, this utility model proposes a wire guide frame locking device, comprising:

[0006] A support frame, wherein a through hole is provided at the first end of the support frame, and a blind hole is provided at the end face of the first end of the support frame extending along the axis of the support frame toward the through hole, wherein the axis of the through hole and the axis of the blind hole are perpendicular to each other and intersect each other.

[0007] The reinforcing member is constructed in a columnar shape, and the interior of the reinforcing member has an insertion hole and a fastening hole, the axes of the insertion hole and the fastening hole being perpendicular to each other and intersecting each other;

[0008] Fasteners are configured such that the fastening end can be connected to the fastening hole and extends into the cross-section of the insertion hole;

[0009] The strength of the reinforcing member is higher than that of the support frame. The reinforcing member can be inserted into the through hole, aligning the blind hole with the insertion hole, so that the rod inserted into the blind hole and the insertion hole can be pressed and fixed by the fastener.

[0010] Preferably, the farthest distance the blind hole extends from the first end of the support frame to the second end is greater than the farthest distance the through hole extends from the support frame to the second end, so that the blind hole forms a through-hole in the side wall of the through hole.

[0011] Preferably, the inner contour of the through hole matches the outer contour of the reinforcing member.

[0012] Preferably, the outer contour of the reinforcing member is a regular polygon or a circle.

[0013] Preferably, the diameter of the blind hole is the same as that of the insertion hole.

[0014] Preferably, the fastening hole is configured as an internally threaded hole that mates with the fastener.

[0015] Preferably, when the blind hole is aligned with the insertion hole, the end face of the reinforcing member is aligned with the outer wall of the support frame.

[0016] Preferably, the length of the fastener is less than or equal to the length of the through hole.

[0017] Preferably, the support frame is a nylon support frame.

[0018] Preferably, the reinforcing member is made of ferrous metal.

[0019] Compared with the prior art, the advantages of this utility model are:

[0020] The wire guide locking device proposed in this application is an improvement on the existing locking device. Reinforcing parts are added to the weak areas of the connection. With minimal improvement cost, it not only meets the process requirements, but also makes the parts wear-resistant and reliable due to the high connection strength between the fasteners and the reinforcing parts. This greatly reduces the possibility of the original nylon cover stripping when tightened, and reduces maintenance. Attached Figure Description

In the drawings, each identical or nearly identical component shown in the various figures may be denoted by the same reference numeral. For clarity, not every component is labeled in each figure. Embodiments of various aspects of the present invention will now be described by way of example and with reference to the accompanying drawings, wherein:

[0023] Figure 2 is a structural schematic diagram of the wire guide locking device shown in this utility model;

[0026] To better understand the technical content of this utility model, specific embodiments are provided below in conjunction with the accompanying drawings.

[0027] Referring to Figure 2, this utility model proposes a wire guide locking device, including a support frame 10, a reinforcing member 20, and a fastener 30. Due to process requirements, the support frame 10 in this application is a nylon support frame. Furthermore, to increase the connection stability of the wire guide spring 01 under stress, the reinforcing member 20 is made of ferrous metal.

[0028] Optionally, the reinforcing component 20 can be made of carbon steel, 45 steel, etc.

[0029] As shown in Figures 2 and 3, the first end of the support frame 10 is provided with a through hole 11, and the end face of the first end of the support frame 10 is provided with a blind hole 12 extending along the axis of the support frame 10 toward the through hole 11. The axis of the through hole 11 and the axis of the blind hole 12 are perpendicular to each other and intersect.

[0030] Thus, compared to the support frame in the prior art, the support frame 10 in this application has two holes at the upper end, namely a through hole 11 and a blind hole 12. The two holes intersect to form a cross-shaped channel, which facilitates the installation of the reinforcing member 20 in the through hole 11, and also allows the rod 02 to be inserted into the blind hole 12.

[0031] As shown in Figure 4, the reinforcing member 20 is constructed as a column. The interior of the reinforcing member 20 is provided with an insertion hole 22 and a fastening hole 21. The axes of the insertion hole 22 and the fastening hole 21 are perpendicular to each other and intersect.

[0032] The insertion hole 22 is used for inserting the rod 02, and the fastening hole 21 is used for inserting the fastener 30. The design of the insertion hole 22 and the fastening hole 21 perpendicularly intersecting each other allows the fastener 30 to contact the rod 02 inserted into the insertion hole 22 after insertion, and the rod 02 is fixed by the fastener 30.

[0033] Furthermore, the fastener 30 is configured such that the fastening end can connect to the fastening hole 21 and extend into the cross-section of the insertion hole 22.

[0034] Specifically, the fastener 30 is a screw, and the fastening end of the screw is the clamping surface at the front end of the screw. When the screw rotates in the fastening hole 21, its clamping surface continuously approaches the insertion hole 22. If the rod 02 is inserted into the insertion hole 22, the rod 02 can be clamped and fixed by the clamping surface of the screw.

[0035] The strength of the reinforcing member 20 is higher than that of the support frame 10. Preferably, the support frame 10 is a nylon support frame, and the reinforcing member 20 is made of ferrous metal.

[0036] As shown in Figure 2, the reinforcing member 20 can be inserted into the through hole 11, so that the blind hole 12 is aligned with the insertion hole 22, and the rod 02 inserted into the blind hole 12 and the insertion hole 22 can be pressed and fixed by the fastener 30.

[0037] Compared with the prior art, in this application, the fastener 30 is connected to the reinforcing member 20, and the insertion section 05 of the rod body 02 is connected to the reinforcing member 20 and the fastener 30. The fastener 30, the rod body 02 and the reinforcing member 20 are all made of metal, which ensures reliable connection and high stability. They will not loosen under stress. At the same time, this locking device not only meets the process requirements, but also has low modification costs and achieves a more reliable locking state.

[0038] As shown in Figure 2, the farthest distance of the blind hole 12 extending from the first end to the second end of the support frame 10 is greater than the farthest distance of the through hole 11 extending from the support frame 10 to the second end, so that the blind hole 12 forms a through hole in the side wall of the through hole 11.

[0039] That is, the lowest position of the blind hole 12 is lower than the lowest position of the through hole 11, so that the rod 02 can completely penetrate the through hole 11 and enter the bottom of the blind hole 12. This insertion method is beneficial for axial positioning of the reinforcing member 20.

[0040] In an optional embodiment, the inner contour of the through hole 11 matches the outer contour of the reinforcing member 20. Thus, when the reinforcing member 20 is inserted into the through hole 11, it will not rotate within the through hole 11, maintaining a relatively stable state, and this also facilitates the alignment of the insertion hole 22 with the blind hole 12.

[0041] In an optional embodiment, the outer contour of the reinforcement 20 is a regular polygon or a circle.

[0042] Preferably, the blind hole 12 and the insertion hole 22 have the same diameter. In this way, when the rod 02 is inserted into the blind hole 12 and the insertion hole 22, the reinforcing member 20 and the support frame 10 will not wobble relative to each other.

[0043] In an optional embodiment, the fastening hole 21 is configured as an internally threaded hole that mates with the fastener 30.

[0044] Preferably, when the blind hole 12 is aligned with the insertion hole 22, the end face of the reinforcing member 20 is aligned with the outer wall of the support frame 10. In this way, when a threaded fastener is screwed into the fastening hole 21 in the reinforcing member 20, the connection between the support frame 10, the reinforcing member 20, the fastener 30, and the rod 02 can be guaranteed to be stable.

[0045] In an optional embodiment, the length of the fastener 30 is less than or equal to the length of the through hole 11. This prevents the reinforcing member 20 from leaking out of the through hole 11 after the rod body 02 and fastener 30 are installed.

[0046] In conjunction with the above embodiments, the wire guide locking device proposed in this application is an improvement on the existing locking device. A reinforcing member is added to the weak area of ​​the connection. With a small improvement cost, it not only meets the process requirements, but also makes the parts wear-resistant and reliable due to the high connection strength between the fastener and the reinforcing member. This greatly reduces the possibility of the original nylon cover stripping when tightened, and reduces the amount of maintenance.

[0047] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
