DETAILED DESCRIPTION

[0018] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0019] Example: like Figure 1-Figure 7 As shown, the present embodiment provides a large jacquard mechanism quick-detachable one-piece knitting machine, comprising a machine body 1 and a machine hood 2 installed on the upper end of the machine body 1, and a side frame 3 is fixed to the side end of the machine body 1 in the length direction; both ends of the side frame 3 are provided with vertical plug interfaces, and two plug-in rods 4 are provided on both sides of the machine hood 2, and each plug-in rod 4 is matched and plugged into a vertical plug interface along the vertical direction, and the positioning installation of the machine hood 2 is realized by the cooperation of the plug-in rod 4 and the vertical plug interface.

[0020] A locking mechanism is installed on both sides of the body 1, and a locking bar 100 in an initial state is slidably connected inside the locking mechanism to drive the locking bar 100 to slide in the locking mechanism by inserting the plug rod 4 into the vertical plug interface, and lock the plug rod 4 when the hood 2 abuts against the upper end of the body 1. Then, when the hood 2 is installed, the plug rod 4 will be inserted into the vertical plug interface as the hood 2 descends. When the hood 2 abuts against the body 1, the locking bar 100 directly locks the plug rod 4, thereby preventing the hood 2 from moving upward and ensuring the stability of the hood 2.

[0021] An unlocking mechanism controlled by a hand wheel 200 is installed between the body 1 and the locking mechanism, which drives the lock bar 100 to slide in the locking mechanism and return to its initial state through the control of the unlocking mechanism by the hand wheel 200, so that the hood 2 can be removed upwards, and the operation of the hand wheel 200 is also simple, convenient and fast.

[0022] When the hood 2 is installed, as the hood 2 falls, the plug-in rod 4 enters the vertical plug-in interface and triggers the locking mechanism at the same time. When the hood 2 abuts against the body 1, the locking bar 100 directly locks the plug-in rod 4, thereby preventing the hood 2 from moving upward, ensuring the stability of the hood 2. This is done in one step without the need for additional locking, which is simple and quick. When the hood 2 needs to be taken out upward, the hand wheel 200 can be directly turned to release the lock on the plug-in rod 4. This is simple and convenient, making it very quick to lock and unlock the hood 2, thereby improving efficiency and facilitating later maintenance.

[0023] As a preferred implementation scheme in this embodiment, it needs to be further explained that the locking mechanism includes a shell 101 installed on the body 1, and the shell 101 can be connected to the body 1 by bolts to realize the loading and unloading of the entire locking mechanism. The shell 101 is set with an opening on one side facing the side frame 3, and a first gear 102 that can drive the lock bar 100 to slide unidirectionally in the direction of the plug-in rod 4 is rotatably connected in the shell 101. For example, when the first gear 102 rotates forward, it can drive the lock bar 100 to slide in the direction of the plug-in rod 4, and when it is reversed, it has no effect on the lock bar 100. An avoidance opening is provided on the side frame 3, and a plurality of tooth grooves evenly distributed in the vertical direction are provided on one side of the plug-in rod 4 facing the locking mechanism. It can be understood that the plug-in rod 4 is a rack structure, and the first gear One side of 102 passes through the avoidance opening and matches and meshes with one side of the plug rod 4, so that when the plug rod 4 moves downward, it can drive the first gear 102 to rotate. At this time, the rotation of the first gear 102 can drive the locking bar 100 to slide in the direction of the plug rod 4; the locking bar 100 is provided with a plurality of teeth matching and meshing with one side of the plug rod 4 at one end of the plug rod 4, so that the teeth at one end of the locking bar 100 can mesh with the tooth grooves at one end of the plug rod 4, thereby locking the plug rod 4. At this time, if the plug rod 4 wants to move upward, it can push the locking bar 100 to slide in the opposite direction, and the upward force given to the locking bar 100 by the plug rod 4 is not enough to drive the locking bar 100 to slide, so the plug rod 4 can be locked by the locking bar 100, that is, the hood 2 is locked.

[0024] As a preferred implementation scheme in this embodiment, it needs to be further explained that the central axis of the first gear 102 is installed with the second gear 104 through the one-way bearing 103, so that when the plug rod 4 is inserted into the vertical plug interface and drives the first gear 102 to rotate, the first gear 102 can drive the second gear 104 to rotate synchronously, and the second gear 104 is spaced apart from the plug rod 4, so that the up and down movement of the plug rod 4 does not directly contact the second gear 104; the top surface of the lock bar 100 is provided with a plurality of tooth grooves evenly distributed along its sliding direction, and the lock bar 100 The top surface of 00 is matched and meshed with the second gear 104, so when the plug-in rod 4 moves downward, the first gear 102 can drive the second gear 104 to rotate, and the second gear 104 drives the lock bar 100 to move toward the plug-in rod 4 and lock the plug-in rod 4; when the hand wheel 200 is rotated and the lock bar 100 is controlled to slide in the opposite direction through the unlocking mechanism, the rotation of the second gear 104 will not drive the central axis of the first gear 102 to rotate, and will not affect the first gear 102 and the plug-in rod 4, and can also ensure that the rotating hand wheel 200 can control the lock bar 100 to return to its initial state.

[0025] As a preferred implementation scheme in this embodiment, it needs to be further explained that at least two first bearings 105 are installed in the housing 101, the inner ring of the first bearing 105 is installed in the housing 101 through the central axis, and the outer ring of the first bearing 105 is supported on the lower end of the lock bar 100, thereby making the sliding of the lock bar 100 smoother and reducing friction. It should be noted that in practice, the top of the lock bar 100 can also engage with the third gear, and the third gear is rotatably connected to the housing 101 through the bearing, so that the third gear always remains in an idling state, which will not affect the sliding of the lock bar 100, but can be limited above the lock bar 100, making the lock bar 100 more stable.

[0026] As a preferred implementation scheme in this embodiment, it needs to be further explained that the unlocking mechanism includes a connecting rod 201 threadedly connected to the other end of the locking bar 100, and the end of the connecting rod 201 away from the locking bar 100 is rotatably connected to the outer shell 101, and the handwheel 200 is transmission-connected to the connecting rod 201, so as to control the sliding of the connecting rod 201 through the handwheel 200 and drive the locking bar 100 to return to its initial state, and then when the handwheel 200 is rotated, the unlocking mechanism controls the rotation of the connecting rod 201, and the locking bar 100 is slidably connected in the outer shell 101, so the rotation of the connecting rod 201 can drive the locking bar 100 to slide and reset.

[0027] As a preferred implementation scheme in this embodiment, it needs to be further explained that the unlocking mechanism also includes a first bevel gear 202 and a second bevel gear 203 that mesh with each other, so that the first bevel gear 202 and the second bevel gear 203 can rotate synchronously, and the connecting rod 201 includes a rotating section and a sliding section that are connected to each other, and the rotating section is rotatably connected to the shell 101, that is, the connecting rod 201 is rotatably connected to the shell 101, and one end of the sliding section is slidably connected to the rotating section. For example, a through hole is provided on the rotating section, and one end of the sliding section is slidably connected to the through hole and can pass through the through hole. The middle part of the sliding section is coaxially connected to the first bevel gear 202 to ensure that the two can rotate synchronously, and the other end of the lock bar 100 is provided with a threaded hole, and the other end of the sliding section is threadedly connected to the threaded hole. In practice, the length of the threaded hole is relatively long, which ensures that the other end of the sliding section is always threadedly connected to The threaded hole at the other end of the locking bar 100 ensures the connection between the two. Because the locking bar 100 is slidably connected to the shell 101, when the sliding section rotates, the locking bar 100 can keep sliding and returning to the initial state. When the locking bar 100 slides in the direction of the plug-in rod, the locking bar 100 can be driven to rotate together without affecting the sliding of the locking bar 100. When the locking bar 100 abuts against the shell 101, the locking bar 100 returns to the initial state. A mounting groove is provided in the shell 101, and the width of the mounting groove is smaller than the width of the locking bar 100. When the locking bar 100 abuts against the shell 101, the locking bar 100 can be kept in the initial state. The first bevel gear 202 is rotatably connected to the mounting groove. The second bevel gear 203 is connected to the hand wheel 200 through the rotating rod 204. The rotating rod 204 is rotatably connected to the body 1 and the shell 101. The structure is simple and practical.

[0028] Preferably, a spring is provided in the threaded hole at the other end of the connecting rod 201, and the spring is used to abut the sliding section. After the locking bar 100 returns to the initial state, the hand wheel is continuously rotated to apply pressure to the sliding section using the spring force, so that the sliding section can be reset.

[0029] As a preferred implementation scheme in this embodiment, it needs to be further explained that the first bevel gear 202 is rotatably connected to the mounting groove through the second bearing 205, an annular protrusion is provided in the mounting groove, the inner ring of the second bearing 205 is connected to the annular protrusion, and the outer ring of the second bearing 205 is connected to the first bevel gear 202, thereby ensuring the flexibility of the first bevel gear 202.

[0030] As a preferred implementation scheme in this embodiment, it needs to be further explained that the end of the body 1 is detachably connected to the annular positioning platform 206 by bolts, which is convenient for loading and unloading. The handwheel 200 is rotatably connected to the annular positioning platform 206 through the third bearing 207, the inner ring of the third bearing 207 is connected to the handwheel 200, and the outer ring of the third bearing 207 is connected to the annular positioning platform 206, so as to ensure the flexibility of the handwheel 200.

[0031] As a preferred implementation scheme in this embodiment, it needs to be further explained that the side frame 3 is a U-shaped structure, and the lower end of the plug-in rod 4 is a conical structure with a cross-section that gradually increases from bottom to top. The structure is simple and practical, and at the same time can ensure that the plug-in rod 4 can stably enter the vertical plug interface.

[0032] As a preferred implementation scheme in this embodiment, it needs to be further explained that an inverted U-shaped handle is connected to the top of the hood 2, which makes it more convenient to control the loading and unloading of the hood 2 on the machine body 1.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
