Description

Technical Field

[0001] This utility model relates to the field of acupuncture machines, and in particular to an adjustable double-sided acupuncture machine. Background Technology

[0002] For example, patent publication number CN217536319U discloses an adjustable needle-punching machine, including a main body. A sliding rail is fixedly connected to one side of the inner wall of the main body, and one side of the sliding rail is slidably connected to a slider. A fixing block is fixedly connected to one side of the inner wall of the main body, and a groove is formed on one side of the fixing block. One end of a spring A is fixedly connected to one side of the inner wall of the groove, and the other end of the spring A is fixedly connected to one side of a clamping plate. The clamping plate is slidably connected to the inner wall of the groove. A connecting plate is fixedly connected to one side of the fixing block, and a hydraulic cylinder is fixedly connected to one side of the inner wall of the main body. An adjustable needle-punching device is provided at the output end of the hydraulic cylinder. By setting an adjustable needle-punching device, the operator can manually move the moving block left and right, causing the moving block to move along two sets of guide rods, thereby changing the position of the needle. This allows the position of the needle to be changed according to the actual situation of the blanket, making the needle-punching more precise at the position of the blanket that needs to be processed.

[0003] It uses a locking block to lock and limit the left and right movement of the movable block, and the locking block is supported and limited by a spring. The sliding locking block squeezes the spring, causing the locking block to separate from the locking teeth on the bracket, so that the position of the movable block and the needle can be adjusted. However, when the hydraulic cylinder drives the bracket and the movable block to move up and down, the locking block will separate from the bracket under its own weight and inertia. This will cause the locking block to lose its limiting function, reduce the stability of the movable block's positioning, and make it difficult to stably lock and limit the movable block after the adjustment limit.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides, for example Figure 1-4 The adjustable double-sided needle punching machine shown includes a main body 1, with mounting frames 2 symmetrically arranged on the main body 1. Hydraulic cylinders are symmetrically fixedly mounted on the main body 1, driving the mounting frames 2 and needle units 4 to reciprocate, thereby performing needle punching on the product. The needle units 4 are slidably arranged inside the mounting frames 2. Each needle unit 4 includes a mounting block 41, a puncture needle 42, a fixing frame 43, a locking assembly 44, and a limiting assembly 45. The puncture needle 42 is fixedly connected to the end of the mounting block 41, which is slidably disposed inside the mounting frame 2. Guide rods are symmetrically fixedly connected inside the mounting frame 2. The guide rod and the mounting block 41 are slidably interlocked, thereby releasing the restriction of the mounting block 41 by the snap-fit ​​component 44. The mounting block 41 slides on the outer wall of the guide rod, which can change the working position of the mounting block 41 and the puncture needle 42. The fixing frame 43 is fixedly connected to the end of the mounting block 41. The snap-fit ​​component 44 is snapped between the fixing frame 43 and the mounting frame 2. The limiting component 45 is disposed inside the fixing frame 43. The limiting component 45 is used to brake and limit the snap-fit ​​component 44. The limiting component 45 uses a blocking limiting method to brake and limit the snap-fit ​​component 44, and the limiting component 45 will not affect the braking and limiting of the snap-fit ​​component 44 due to up and down movement.

[0028] Specifically, the snap-fit ​​assembly 44 includes a connecting block 441, a limiting snap-fit ​​tooth 442, and a snap-fit ​​tooth strip 443. The outer wall of the connecting block 441 is slidably inserted into the fixing frame 43. The limiting snap-fit ​​tooth 442 is fixedly connected to the side of the connecting block 441 away from the mounting block 41. The limiting snap-fit ​​tooth 442 is fixedly connected to the inside of the mounting frame 2. The limiting snap-fit ​​tooth 442 and the snap-fit ​​tooth strip 443 are engaged. That is, when the limiting snap-fit ​​tooth 442 and the snap-fit ​​tooth strip 443 are engaged, the fixing frame 43 can be snapped and limited, thereby positioning the mounting block 41 and the puncture needle 42.

[0029] In particular, the limiting assembly 45 includes a fixed plate 451, a connecting rod 452, and a limiting plate 453. The fixed plate 451 is fixedly connected to the side of the inner wall of the fixed frame 43. The limiting plate 453 is slidably connected to the fixed plate 451 through the connecting rod 452. That is, the limiting plate 453 can only move horizontally inside the fixed frame 43 and will not slide up and down relative to the fixed frame 43. Therefore, when the limiting plate 453 presses and limits the connecting block 441, it can ensure the stability of the engagement between the connecting block 441 and the limiting tooth 442 and the toothed strip 443. The top of the limiting plate 453 is connected to the connecting block 441. 1. The limiting plate 453 is fixedly sleeved on the outer wall of the connecting rod 452. The outer wall of the connecting rod 452 is slidably inserted and sleeved with the fixing plate 451. The bottom of the connecting block 441 is symmetrically provided with slots 457 that match the connecting rod 452. That is, when the sliding limiting plate 453 and the connecting block 441 are misaligned, the connecting block 441 slides into the fixing frame 43, so that the limiting tooth 442 separates from the toothed strip 443. At this time, the connecting block 441 can be sleeved on the outer wall of the connecting rod 452 through the slot 457, so as to prevent the connecting rod 452 from affecting the movement of the connecting block 441.

[0030] Furthermore, a handle 458 is symmetrically fixedly connected to one side of the connecting block 441. The handle 458 can drive the connecting block 441 to slide and reset. The handle 458 is located between the fixed plate 451 and the fixed frame 43. A limit spring 454 is slidably sleeved on the outer wall of the connecting rod 452. There are two connecting rods 452, two limit springs 454, and two fixed plates 451. The limit plate 453 is located between the two fixed plates 451. The connecting plate 455 and the limit block 456 are located between the two fixed plates 451. On one side of the back, a connecting plate 455 is fixedly connected to one end of the connecting rod 452, and a limiting spring 454 is located between the connecting plate 455 and the fixed plate 451. A limiting block 456 is fixedly connected to the other end of the connecting rod 452. Thus, under the action of the limiting spring 454, the connecting plate 455 and the limiting block 456, the limiting plate 453 can be stably located at the bottom of the connecting block 441. By squeezing the connecting plate 455, the connecting rod 452 can drive the limiting plate 453 to slide and be misaligned with the connecting block 441.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
