Description

Technical Field

[0001] This utility model belongs to the field of knitting machinery technology and relates to a reinforced transfer needle. Background Technology

[0002] In the sock production process, the transfer needle needs to cooperate with the vertical knitting needles of the sock machine to transfer sock yarn as it moves axially. Existing transfer needles are prone to instability during movement due to external factors such as vibration. To overcome the shortcomings of existing technologies, various solutions have been proposed through continuous exploration. For example, Chinese patent discloses a novel transfer needle and transfer device [Application No.: 2025203735963], which includes a needle body with a hook at the front end. The novel transfer needle also includes a needle seat extending axially along the needle body and connected to the needle body via at least two mortise and tenon structures. The positions of the mortise and tenon structures are spaced apart along the axial direction of the needle body, so that the needle body is suspended and connected to the needle seat. The mating direction between the tenon and the mortise in the mortise and tenon structure is the axial direction of the needle body.

[0003] In the novel transfer needle described above, the needle body and needle seat are connected via a mortise and tenon joint. However, in actual production, the transfer needle needs to perform frequent axial reciprocating movements, and the working environment is subject to continuous vibration. This can easily lead to the failure of the connection between the needle body and the needle seat, causing the mortise and tenon joint to lose its axial constraint and ultimately resulting in the axial separation of the needle body and the needle seat. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems by providing a reinforced transfer needle.

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

[0006] A reinforced transfer needle includes a needle body, a hook tongue at the front end of the needle body, a needle seat at the top of the needle body for suspending the needle body, at least two positioning bodies distributed along the axial direction of the needle body on the needle body, and the positioning bodies are integrated with the needle body. The positioning bodies pass through the positioning groove of the needle seat, and one end of the positioning body is connected to the needle seat through a tenon and mortise structure that aligns along the axial direction of the needle body. A gap is formed between the other end of the positioning body and the positioning groove. At least one gap is provided with a stop member that can axially constrain the needle seat and limit the needle body to prevent the tenon and mortise structure from axially disengaging.

[0007] At least one stop member in the empty area can axially constrain the needle seat and the limiting needle body to prevent the mortise and tenon structure from axially separating. When the mortise and tenon structure fails and loosens, the physical blockage of the stop member can prevent the needle seat and the needle body from axially separating. The double insurance mechanism significantly improves the connection stability between the needle body and the needle seat and effectively prevents separation.

[0008] In the aforementioned reinforced transfer needle, the stop member includes an anti-displacement top body disposed at the other end of the positioning body and at least a portion of which is located in the positioning groove, capable of axially positioning the needle seat and the needle body.

[0009] The anti-shifting top acts directly between the needle holder and the needle body, providing a reliable axial constraint force, effectively preventing the loosening and separation of the tenon and mortise structure, and ensuring the connection stability between the needle body and the needle holder.

[0010] In the aforementioned reinforced transfer needle, one end of the anti-shifting top body is integrated with the positioning body and / or the needle body, the other end of the anti-shifting top body abuts against the other end of the positioning groove, and the height of the top surface of the anti-shifting top body is between the height of the bottom surface and the height of the top surface of the positioning groove.

[0011] The integrated design of the anti-shifting top body, positioning body, and / or needle body improves the overall strength of the structure. The stable support of the anti-shifting top body in the positioning groove forms an effective axial constraint. The height of the top surface of the anti-shifting top body is between the height of the bottom surface and the top surface of the positioning groove, avoiding interference with assembly and ensuring the stability and reliability of the anti-shifting top body in the positioning groove.

[0012] In the above-mentioned reinforced transfer needle, the needle seat is strip-shaped, the anti-shifting top is disposed on the rear end of the needle seat and the needle body, and the other end of the anti-shifting top is provided with a chamfer that facilitates the needle seat to bend and snap into place so that the other end of the positioning groove axially abuts against the other end of the anti-shifting top.

[0013] The stop mechanism is located at the rear end of both the needle holder and the needle body, making full use of the rear space and improving the overall structural stability. The chamfered design facilitates the installation and removal of the needle holder, improving installation efficiency.

[0014] In the aforementioned reinforced transfer needle, the anti-displacement top body includes a wedge, which is inserted into the empty area, with one side abutting against the positioning body and / or the needle body, and the other side abutting against the other end of the positioning groove.

[0015] The wedge structure is simple and easy to install. By inserting and abutting the wedge, axial constraint is achieved on the needle seat and the needle body, effectively preventing the loosening and separation of the tenon and mortise structure.

[0016] In the aforementioned reinforced transfer needle, the anti-displacement top body is welded or bonded to at least one of the positioning body, needle seat, or needle body.

[0017] By welding or bonding, the connection strength of the anti-displacement top body is further improved, effectively preventing the loosening and separation of the needle body and needle seat.

[0018] In the aforementioned reinforced transfer needle, the tenon and mortise structure includes a tenon groove provided on one end of the positioning body. The needle body and the needle seat move axially relative to each other to change the axial position of the positioning body and the positioning groove so that the tenon groove and the needle seat are tenoned together.

[0019] The mortise and tenon joint achieves axial relative movement, simplifying the installation process and improving installation efficiency. At the same time, the mortise and tenon structure can withstand larger axial forces, improving the stability of the connection.

[0020] In the aforementioned reinforced transfer pin, a stamping groove is provided between each tenon and the top surface of the pin body;

[0021] And / or, at least one end of the positioning groove is provided with an axial central protrusion located between the two sides, forming a retraction groove between the central protrusion and the side wall of the positioning groove.

[0022] The stamping process groove allows the tenon to fully engage with the pin seat during movement, effectively improving the accuracy and reliability of the tenon joint. The central protrusion serves as a rigid reference, constraining the axial position of the positioning body and preventing it from shifting. The recessed groove provides clearance, ensuring a complete fit between the tenon and the axial central protrusion.

[0023] In the aforementioned reinforced transfer needle, the width of the needle hub is greater than the width of the needle body.

[0024] It can provide more stable support and prevent the needle from tilting or twisting when subjected to force.

[0025] In the aforementioned reinforced transfer needle, the positioning body at the rear end of the needle body is provided with a force-bearing body for driving the axial movement of the needle body.

[0026] The needle body is also provided with a reset force receiving part at the rear end.

[0027] The design of the force-bearing body facilitates the external drive mechanism to apply axial force to the needle body, driving the needle body to move. The design of the reset force-bearing part facilitates the needle body to return to its original position after movement.

[0028] Compared with existing technologies, the advantages of this invention are: 1. The physical blocking of the stop component prevents the mortise and tenon structure from axially disengaging, and the double-safety mechanism significantly improves the connection stability between the needle body and the needle seat. 2. The needle seat is thinner and lighter, making assembly with the needle body simple and efficient. 3. It effectively reduces the risk of loose solder joints, thus extending the service life of the transfer needle. Attached Figure Description

Detailed Implementation

[0038] Example 1

[0039] like Figures 1-5 As shown, a reinforced transfer needle includes a needle body 1, a hook tongue 2 at the front end of the needle body 1, a needle seat 3 for suspending the needle body at the top of the needle body 1, at least two positioning bodies 4 distributed along the axial direction of the needle body 1 on the needle body 1, and the positioning bodies 4 are integrated with the needle body 1. The positioning bodies 4 pass through the positioning groove 5 of the needle seat 3, and one end of the positioning body 4 is connected to the needle seat 3 through a tenon structure 6 that is aligned along the axial direction of the needle body 1. A gap area 7 is formed between the other end of the positioning body 4 and the positioning groove 5. At least one gap area 7 is provided with a stop member 8 that can axially constrain the needle seat 3 and limit the needle body 1 to prevent the tenon structure 6 from axially disengaging.

[0040] In this utility model, the positioning body 4 is integrated with the needle body 1, and the positioning groove 5 of the needle seat 3 is inserted to form a preliminary suspension and limiting. The tenon and mortise structure 6 is connected along the axial direction of the needle body to achieve the preliminary fixation of the needle body 1 and the needle seat 3, and welding is used to enhance the connection strength.

[0041] Traditional welding processes are prone to failure due to unstable weld quality, which can lead to the failure of the connection between the needle body 1 and the needle seat 3. This causes the tenon and mortise structure 6 to lose its axial constraint, ultimately resulting in the axial separation of the needle body 1 and the needle seat 3.

[0042] In this embodiment, at least one stop member 8 within the empty area 7 can axially constrain the needle seat 3 and the limiting needle body 1, preventing the tenon structure 6 from axially separating. When the tenon structure 6 loosens due to welding failure, the physical obstruction of the stop member 8 can prevent the needle seat 3 from axially separating from the needle body 1. This double-safety mechanism significantly improves the connection stability between the needle body 1 and the needle seat 3, effectively preventing separation. Furthermore, it can effectively reduce the risk of weld loosening and effectively extend the service life of the transfer needle.

[0043] Specifically, combining Figures 1-3 As shown, the stop member 8 includes an anti-displacement top body 9 disposed at the other end of the positioning body 4 and at least part of which is located in the positioning groove 5, capable of axially positioning the needle seat 3 and the needle body 1.

[0044] The anti-displacement top body 9 is located at the other end of the positioning body 4, and at least part of it is located in the positioning groove 5. The anti-displacement top body 9 axially positions the needle seat 3 and the needle body 1 by means of physical blocking.

[0045] The anti-shifting top body 9 acts directly between the needle seat 3 and the needle body 1, providing a reliable axial constraint force, effectively preventing the loosening and separation of the tenon structure 6, and ensuring the connection stability between the needle body 1 and the needle seat 3.

[0046] Specifically, combining Figures 1-3 As shown, one end of the anti-slip top body 9 is integrated with the positioning body 4 and / or the needle body 1, and the other end of the anti-slip top body 9 abuts against the other end of the positioning groove 5, and the height of the top surface of the anti-slip top body 9 is between the height of the bottom surface and the height of the top surface of the positioning groove 5.

[0047] The integrated design of the anti-shifting top body 9 with the positioning body 4 and / or the needle body 1 improves the overall strength of the structure. The stable support of the anti-shifting top body 9 in the positioning groove 5 forms an effective axial constraint. The height of the top surface of the anti-shifting top body 9 is between the height of the bottom surface and the height of the top surface of the positioning groove 5, avoiding interference with assembly and ensuring the stability and reliability of the anti-shifting top body 9 in the positioning groove 5.

[0048] Specifically, combining Figures 1-5 As shown, the needle seat 3 is strip-shaped, and the anti-shifting top body 9 is set on the rear end of the needle seat 3 and the needle body 1. The other end of the anti-shifting top body 9 is provided with a chamfer 10 that facilitates the bending and insertion of the needle seat 3 so that the other end of the positioning groove 5 axially abuts against the other end of the anti-shifting top body 9.

[0049] The stop component 8 is set on the rear end of the needle holder 3 and the needle body 1, making full use of the space at the rear end and improving the stability of the overall structure. The chamfer 10 at the other end of the anti-slip top body 9 makes it easy for the other end of the positioning groove 5 to smoothly abut against the other end of the anti-slip top body 9 when the needle holder 3 is bent and inserted. The design of the chamfer 10 facilitates the installation and disassembly of the needle holder 3 and improves the installation efficiency.

[0050] In this embodiment, the needle holder 3 is thinner and lighter. In order to prevent the needle holder 3 from bending, three positioning bodies 4 are provided on the needle body 1 along the axial direction of the needle body 1. The needle body 1 is suspended and fixed under the needle holder 3 by three tenon and mortise structures 6.

[0051] Specifically, combining Figures 1-3 As shown, the anti-displacement top body 9 is welded or bonded to at least one of the positioning body 4, needle seat 3, or needle body 1.

[0052] like Figure 2 As shown at weld point A, in this embodiment, the other end of the anti-shifting top body 9 is welded to the other end of the positioning groove 5. By welding, the other end of the anti-shifting top body 9 and the other end of the positioning groove 5 are fixedly connected, which further improves the connection strength between the anti-shifting top body 9 and the positioning groove 5 and effectively prevents the loosening and separation of the needle body 1 and the needle seat 3.

[0053] Specifically, combining Figures 2-5 As shown, the mortise and tenon structure 6 includes a tenon groove 15 set on one end of the positioning body 4. The needle body 1 and the needle seat 3 move axially relative to each other to change the axial position of the positioning body 4 and the positioning groove 5 so that the tenon groove 15 and the needle seat 3 are tenoned together.

[0054] The mortise and tenon structure 6 is achieved by the tenon groove 15 on one end of the positioning body 4 and the tenon joint with the needle seat 3. By moving the needle body 1 and the needle seat 3 axially relative to each other, the axial position of the positioning body 4 and the positioning groove 5 is changed, so that the tenon groove 15 and the needle seat 3 are tenoned together, forming a preliminary fixation.

[0055] The mortise and tenon joint is achieved through axial relative movement, simplifying the installation process and improving installation efficiency. At the same time, the mortise and tenon structure 6 can withstand greater axial forces, improving the stability of the connection.

[0056] Specifically, combining Figure 2 and Figure 3 As shown, each tenon 15 is provided with a stamping process groove 16 between it and the top surface of the pin body 1;

[0057] And / or, at least one end of the positioning groove 5 is provided with an axial central protrusion 18 located between the two sides, and a retraction groove 17 is formed between the central protrusion 18 and the side wall of the positioning groove 5.

[0058] The stamping process groove 16 is widened, which reduces the local stress concentration caused by material accumulation during the stamping process, thereby reducing the possibility of cracking of the positioning body 4.

[0059] The stamping process groove 16 allows the tenon 15 to fully engage with the pin seat 3 when it moves, which can effectively improve the accuracy and reliability of the tenon joint.

[0060] The central protrusion 18 on at least one end of the positioning groove 5 serves as a rigid reference, which can constrain the axial position of the positioning body 4 and prevent it from shifting. The retraction groove 17 plays a role in making way to ensure a complete fit between the tenon 15 and the axial central protrusion 18.

[0061] Specifically, combining Figure 1 and Figure 3 As shown, the width of the needle holder 3 is greater than the width of the needle body 1.

[0062] The needle holder 3 protrudes from the side walls of the needle body 1 on both sides, forming a T-shaped structure. This provides more stable support and prevents the needle body 1 from tilting or twisting under force.

[0063] Specifically, combining Figures 1-4 As shown, the positioning body 4 at the rear end of the needle body 1 is provided with a force-receiving body 19 for driving the needle body 1 to move axially.

[0064] The needle body 1 is also provided with a reset force receiving part 20 at the rear end.

[0065] The force-receiving body 19 is provided to facilitate the external drive mechanism to apply axial force to the needle body 1 and drive the needle body 1 to move. The reset force-receiving part 20 is provided to facilitate the needle body 1 to return to its original position after movement.

[0066] After being subjected to force, the force-receiving body 19 can drive the needle body 1 to move along the axial direction of the needle body 1. The reset force-receiving part 20 includes a reset force-applying half-hole 21 provided on the rear end of the needle body 1. A tension spring, similar to the annular tension spring in a lip seal, can be provided in the reset force-applying half-hole 21. For details, please refer to the prior art. When the needle body 1 moves outward along the axial direction of the needle body 1, the tension spring is pulled outward and deformed, which can apply an axial inward reset force to the needle body 1, thereby causing the needle body 1 to move and reset along the axial direction of the needle body 1.

[0067] The working principle of this utility model is as follows: by moving the needle body 1 and the needle seat 3 axially relative to each other, the tenon groove 15 is tenoned with the needle seat 3. When the needle seat 3 is bent and inserted, the other end of the positioning groove 5 axially abuts against the other end of the anti-shifting top body 9. The anti-shifting top body 9 directly acts between the needle seat 3 and the needle body 1, providing a reliable axial constraint force. The other end of the anti-shifting top body 9 is fixedly connected to the other end of the positioning groove 5 by welding, ensuring that the tenon structure 6 will not loosen or detach.

[0068] Example 2

[0069] like Figures 6-8 As shown, the structure and working principle of this embodiment are basically the same as those of Embodiment 1. The difference is that the anti-displacement top body 9 includes a wedge 11, which is inserted into the empty area 7. One side abuts against the positioning body 4 and / or the needle body 1, and the other side abuts against the other end of the positioning groove 5.

[0070] The wedge block 11 has a simple structure and is easy to install. By inserting and abutting the wedge block 11, the axial constraint on the needle seat 3 and the needle body 1 is achieved, effectively preventing the loosening and separation of the tenon and mortise structure 6.

[0071] Specifically, combining Figures 6-8 As shown, the wedge 11 is inverted L-shaped and includes a vertical insertion end 12. A horizontal abutment end 13 is provided at the upper end of the vertical insertion end 12. One side of the vertical insertion end 12 abuts against the positioning body 4 and / or the needle body 1, and the other side abuts against the other end of the positioning groove 5. The bottom surface of the horizontal abutment end 13 abuts against the top surface of the needle seat 3. An easy-entry ramp 14 is provided at the lower end of the vertical insertion end 12. The easy-entry ramp 14 facilitates the insertion of the vertical insertion end 12.

[0072] like Figure 7 As shown in the welding point B, the bottom end of the vertical insertion end 12 is welded to the positioning body 4 to reinforce the connection.

[0073] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0074] Although this article uses terms such as needle body 1, hook tongue 2, needle seat 3, positioning body 4, positioning groove 5, tenon and mortise structure 6, empty area 7, stop component 8, anti-slip top body 9, chamfer 10, wedge block 11, vertical insertion end 12, horizontal abutment end 13, easy-entry slope 14, tenon groove 15, stamping process groove 16, retraction groove 17, axial center protrusion 18, force-bearing body 19, reset force-bearing part 20, reset force-applying half hole 21, welding point A, welding point B, etc., these terms are used only to more conveniently describe and explain the essence of this utility model; interpreting them as any kind of additional limitation would be contrary to the spirit of this utility model.
