DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0034] Please refer to Figures 1-11 The utility model provides a technical scheme: Embodiment 1

[0035] A mute slide lock device applied to a racket threading machine, including slide lock seat 1, the bottom of slide lock seat 1 is provided with slider 11 for being slidably clamped with slide rail 4, the both ends of slider 11 are rotatably provided with follow-up bearing 12 for being slidably contacted with the inner wall of slide rail 4, the ground of slide lock seat 1 is provided with mute plate 10 for being slidably contacted with slide rail 4, the inner bottom of slide lock seat 1 is provided with locking mechanism for driving slider 11 vertical lifting action, the top of slide lock seat 1 is provided with locking turntable 2 for controlling the action of locking mechanism;

[0036] The locking mechanism includes taper block 13, the inner bottom of slide lock seat 1 is provided with taper block sliding port 14, taper block 13 is vertically slidably clamped in taper block sliding port 14 and is connected with slider 11 at the bottom, inner boss 16 is fixed in slide lock seat 1, taper block sliding port 14 is throughly provided in inner boss 16, the outer ring of inner boss 16 and the inner wall of slide lock seat 1 are enclosed to form inner ring groove 15, movable inner ring 3 is sleeved in inner ring groove 15, adjusting stud 31 is threadedly provided in the right side wall of movable inner ring 3, push block 32 is slidably passed through inner boss 16 and is fixed in adjusting stud 31, push block 32 is slidably contacted with taper block 13, the right side of slide lock seat 1 is provided with vertical port for the outer end of adjusting stud 31 to leak out, turntable shaft 23 is vertically rotatably installed at the left side end of inner ring groove 15, the top of turntable shaft 23 is fixedly connected with locking turntable 2, cam 22 is fixedly connected with the middle part of turntable shaft 23, turntable shaft 23 is located in the 3 inner ring, and cam 22 is slidably contacted with the left side inner wall of movable inner ring 3;

[0037] During operation, the slide lock seat 1 relies on the sliding engagement of the slider 11 and the slide rail 4. The two-section follower bearings 12 greatly improve the smoothness of contact, effectively reduce the friction between the slider 11 and the guide rail, enhance the smoothness of the slider 11 during sliding, and reduce the sliding caused by the gap between the slider 11 and the inner wall of the guide rail during locking. The silent plate 10 is a polytetrafluoroethylene friction plate, which replaces the metal friction with the guide rail surface, improving the sensitivity of sliding and rotation, reducing friction noise, and reducing metal shavings caused by metal-to-metal friction, thus reducing the frequency of cleaning and maintenance. The slide lock seat 1 can drive the slider to lock at any position and in any direction on the guide rail groove, achieving stepless adjustment and ultra-quiet and ultra-lubricated sliding effect. When it is necessary to lock and limit the slide lock seat 1, rotating 2,2 drives the turntable shaft 23 to rotate, and the turntable shaft 23 drives the cam 22 to rotate. Figure 8 As shown, the cam 22 will drive the movable inner ring 3 to move laterally in the inner ring groove 15 to the left. As a result, the movable inner ring 3 will drive the push block 32 on the stud spring 33 to move laterally into the conical block slide 14. The push block 32 will lift the conical block slide 14, and the slider 11 connected to the bottom of the conical block slide 14 will also be lifted upward, thereby clamping the slider 11 and the sliding lock seat 1, realizing the position limitation of the sliding lock seat 1. The adjustment is convenient and quick. Moreover, the adjustable stud 31 can adjust the depth of insertion into the conical block slide 14, thereby changing the final height of the push block 32 driving the conical block 13 to rise, that is, changing the clamping degree of the slider 11 locking the guide rail, adapting to different clamping force requirements.

[0038] Among them, a side support spring 30 for pressing the cam 22 against the movable inner ring 3 is fixed between the right inner wall of the movable inner ring 3 and the outer wall of the inner boss 16, and a stud spring 33 for preventing the adjusting stud 31 from loosening is sleeved on the outer end of the adjusting stud 31.

[0039] During operation, the side support spring 30 can easily press the movable inner ring 3 against the cam 22, making it easier for the cam 22 to rotate and drive the movable inner ring 3 to perform displacement. The stud spring 33 is mainly used to facilitate the loosening of the stud 31.

[0040] The slider 11 has an inverted T-shaped cross section. The slider 11 slides through the slide rail 4 from bottom to top and is fixedly connected to the cone block 13. Two follower bearings 12 are installed side by side at both ends of the slider 11 relative to the inner groove wall of the slide rail 4. The follower bearings 12 are slidably connected to the inner groove wall of the slide rail 4.

[0041] During operation, the slider 11, together with the soundproof plate 10, clamps the slide rail 4 in the middle. By adjusting the extension of the slider 11 relative to the bottom of the slide lock seat 1, the clamping and loosening states can be achieved, thereby adjusting the relative sliding speed or locking state of the slide lock seat 1 on the slide rail 4.

[0042] The sliding lock base 1 has a vertically sliding locking pin 24 installed on it. The bottom of the locking pin 24 is provided with a locking pin spring 25. The bottom surface of the locking turntable 2 is provided with a locking slot 21 for locking the top of the locking pin 24. The top of the locking turntable 2 is provided with an unlocking push post 20 that slides into the locking slot 21.

[0043] When the locking turntable 2 is rotated to the pressing state, in order to prevent the locking turntable 2 from rotating without adjusting external force, the locking pin 24 will be inserted into the locking hole 21 in the pressing state position, thereby restricting the rotation of the locking turntable 2 and realizing the angle preservation function of the locking turntable 2.

[0044] Among them, a stop bar and a stop bar arc groove are provided between the bottom of the locking turntable 2 and the top of the sliding lock seat 1 to limit the rotation range of the locking turntable 2;

[0045] During operation, since the locking disc 2 only drives the cam 22 within a range of less than one semicircle to achieve the pushing function of the cam 22 on the movable inner ring 3, the locking disc 2 does not need to rotate. However, the lack of a limit on the locking disc 2 could easily lead to over-rotation. After the cam 22 reaches its most convex position and acts on the movable inner ring 3, it will retract, reducing the displacement of the movable inner ring 3. Therefore, it is best to limit the rotation angle of the locking disc 2. This setting also facilitates quick adjustment of the locking disc 2 and ensures that the operator understands the locking status. Figure 9 As shown, an arc-shaped groove, namely the stop bar arc groove, is opened at the bottom of the locking turntable 2. The stop bar is slidably inserted in the stop bar arc groove. The stop bar section at this position is fixedly installed on the top of the sliding lock seat 1. Thus, the rotation angle of the locking turntable 2 can be limited within a certain range. Example 2

[0046] The difference between this embodiment and Embodiment 1 is that:

[0047] The bottom of the locking turntable 2 is provided with a plurality of friction recesses 26 arranged along the circumferential direction;

[0048] When working, the lock pin 24 is located in the fully compressed state. When other working conditions require to slow down the sliding speed of the slide lock base 1 or improve the sliding damping effect of the slide lock base 1, the lock pin 24 can be embedded into the friction notch 26. When the locking turntable 2 is twisted by external force, the lock pin 24 can be directly unlocked from the friction notch 26 due to the elasticity of the lock pin 24 and the matching chamfer, so that the unlocking column 20 is not required to be additionally arranged for locking. The purpose is that when the slide lock base 1 is subjected to large damping or impact, the lock pin 24 can be instantly unlocked from the friction notch 26, the slide lock base 1 returns to the state of minimum friction, and the slide lock base 1 is conveniently and smoothly passed or bounced back, so that the direct damage to the structural member in the case of large damping or impact is overcome.

[0049] The locking turntable 2 is provided with a convenient adjusting knob.

[0050] When working, the knob is convenient to drive the locking turntable 2 to rotate.
