Description

Technical Field

[0001] This utility model relates to the field of comb technology, and in particular to a comb arm locking mechanism. Background Technology

[0002] The guide bar arm serves as a support structure for the guide bar, ensuring its stable installation within the machine. Simultaneously, it allows the guide bar to oscillate or move as needed to adapt to different weaving requirements. This oscillation or movement function enables the guide bar to accurately guide the yarn, forming the desired fabric structure.

[0003] Currently, traditional comb arm systems on the market are fixedly mounted on a hanger shaft, allowing the comb arm to swing by rotating the hanger shaft. However, during long-term operation, the contact surface between the comb arm and the hanger shaft will wear down, and under continuous stress, micro-cracks will appear in the comb arm material, leading to material fatigue, which in turn will propagate and cause the overall structure to loosen.

[0004] This reduces the tightness and stability of the comb arm connection, causing the comb arm to be unable to be stably locked onto the hanger shaft, preventing it from rotating synchronously with the hanger shaft. Therefore, a comb arm locking mechanism is urgently needed. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a comb arm locking mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The comb arm locking mechanism includes a hanging shaft, a comb arm, and a locking mechanism. The comb arm is fitted with a detachable locking mechanism by screws, and the comb arm is fixedly sleeved on the hanging shaft. Both the comb arm and the locking mechanism have circular inner cavities adapted to the hanging shaft. The locking mechanism has an adjustment notch with an adjustment column rotatably mounted on the adjustment notch, and the locking mechanism also has a side cavity.

[0008] Furthermore, in a preferred configuration, the locking mechanism has multiple through holes, and the comb arm has corresponding screw holes that are adapted to fit the through holes, and both the through holes and screw holes are adapted to fit screws.

[0009] Furthermore, in a preferred configuration, the locking mechanism has a through threaded cavity extending outward on one side of the adjustment notch, and a through cavity on the other side of the adjustment notch.

[0010] Furthermore, in a preferred configuration, the locking mechanism has a communicating anti-detachment cavity at the end of the through cavity, and the diameter of the anti-detachment cavity is larger than the diameter of the through cavity.

[0011] In addition, a preferred structure is that the adjusting column is rotatably inserted on both sides of the adjusting notch, and the end of the adjusting column is fixedly provided with an anti-dropping component corresponding to the anti-dropping cavity.

[0012] In addition, in a preferred configuration, the other end of the adjusting column extends out of the threaded cavity and is fixedly connected to the knob, and an external thread is adapted to fit the threaded cavity on the adjusting column.

[0013] The beneficial effects of this utility model are as follows: the comb arm is mounted on the hanging shaft and swings synchronously. By mounting the locking mechanism on the comb arm and controlling the locking mechanism to lock the hanging shaft twice through the adjusting column, the stability of the comb arm mounted on the hanging shaft can be improved, thereby improving the locking effect of the comb arm on the hanging shaft.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-7 The comb arm locking mechanism includes a hanging shaft 1, a comb arm 2, and a locking mechanism 3. The comb arm 2 is fitted with a detachable locking mechanism 3 via screws 5, and the comb arm 2 is fixedly mounted on the hanging shaft 1. Both the comb arm 2 and the locking mechanism 3 have corresponding circular inner cavities on the hanging shaft 1. The locking mechanism 3 has an adjustment notch 36, on which an adjustment post 4 is rotatably mounted. The locking mechanism 3 also has a side cavity 32.

[0024] The locking mechanism 3 has multiple through holes 31, and the comb arm 2 has corresponding screw holes 21 on each of the through holes 31. Both the through holes 31 and the screw holes 21 are compatible with screws 5. By passing the screws 5 through the through holes 31 and inserting them into the screw holes 21, the locking mechanism 3 can be fixedly installed on the comb arm 2.

[0025] The locking mechanism 3 has a through threaded cavity 33 on one side of the adjustment notch 36 and a through cavity 34 on the other side of the adjustment notch 36.

[0026] The locking mechanism 3 has a communicating anti-detachment cavity 35 at the end of the through cavity 34, and the diameter of the anti-detachment cavity 35 is larger than the diameter of the through cavity 34. The adjusting column 4 is rotatably inserted into both sides of the adjusting notch 36, and an anti-detachment component 41 is fixedly provided at the end of the adjusting column 4 corresponding to the anti-detachment cavity 35. The anti-detachment component 41 prevents the end of the adjusting column 4 from falling off from the other side of the adjusting notch 36, thus allowing the size of the adjusting notch 36 to be adjusted by rotating the adjusting column 4.

[0027] The other end of the adjusting column 4 extends from the threaded cavity 33 and is fixedly connected to the knob 43. The adjusting column 4 is provided with an external thread 42 corresponding to the threaded cavity 33. It is worth noting that the external thread 42 on the adjusting column 4 is not located near the through cavity 34. This is to prevent the external thread 42 from interfering with the rotation of the adjusting column 4 due to interference from the through cavity 34.

[0028] In this embodiment, the comb arm 2 is mounted on the hanging shaft 1 by an interference fit, so that the rotation of the hanging shaft 1 can drive the comb arm 2 to swing. It is worth noting that the specific structure and working method of the hanging shaft 1 and the comb arm 2 are existing technologies, and therefore will not be described in detail in this utility model.

[0029] Furthermore, after the comb arm 2 is installed, the user can assemble the locking mechanism 3 on one side of the comb arm 2 and insert the screw 5 through the through hole 31 into the screw hole 21, thereby fixing the locking mechanism 3 on the comb arm 2. The user can then use the locking mechanism 3 to lock the hanging shaft 1, thereby improving the stability of the comb arm 2 on the hanging shaft 1.

[0030] Furthermore, when the user needs to lock the hanging shaft 1 using the locking mechanism 3, they only need to use a wrench to turn the knob 43, causing the adjusting column 4 to rotate towards the threaded cavity 33. At this time, the anti-dislodgement part 41 on the adjusting column 4 can pull the other side of the adjusting notch 36, thereby reducing the size of the adjusting notch 36 by rotating the adjusting column 4, and thus simultaneously reducing the inner cavity size of the locking mechanism 3, so that the inner cavity of the locking mechanism 3 clamps the hanging shaft 1, thereby fixing the locking mechanism 3 in place inside the hanging shaft 1. In this way, the hanging shaft 1 can be locked a second time by the locking mechanism 3, thereby improving the installation stability of the comb arm 2 on the hanging shaft 1.

[0031] Furthermore, by setting the side cavity 32, the adjustability of the locking mechanism 3 can be improved, thereby enhancing the adjustment stroke of the adjustment notch 36 and improving the clamping effect of the locking mechanism 3 on the hanging shaft 1.

[0032] In this invention, the comb arm 2 is mounted on the hanging shaft 1 and swings synchronously. By mounting the locking mechanism 3 on the comb arm 2 and controlling the locking mechanism 3 to lock the hanging shaft 1 a second time through the adjusting column 4, the stability of the comb arm 2 mounted on the hanging shaft 1 can be improved, thereby improving the locking effect of the comb arm 2 on the hanging shaft 1.

[0033] 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.
