Description

Technical Field

[0001] The utility model belongs to the technical field of guide devices, and in particular relates to an acupuncture guide device. Background Art

[0002] The battery puncture test is an important experiment to determine the safety of the battery. By simulating the puncture situations that the battery may encounter during use, it is evaluated whether it will explode or leak, thereby ensuring the safety of the battery during use. The experimental steps include: 1. Sample placement: Place the battery to be tested on the laboratory bench; 2. Needle setting: Set the needle according to the experimental parameters; 3. Needle insertion: Insert the needle into the battery according to the set parameters and record the data; 4. Measure voltage: Record the voltage of the battery to be tested every 30 seconds; 5. Needle removal: After the needle insertion time reaches the set time, remove the needle from the battery; 6. Record data: Record the data of each experiment, including the appearance, volume, leakage, deformation, etc. of the battery;

[0003] The existing guide device for battery puncture test generally realizes guidance through a guide column and a guide ring. However, due to the influence of ambient temperature and impurities in the air, the guide is prone to jamming. Therefore, in order to ensure smooth guidance, it is necessary to add lubricating oil between the guide column and the guide ring in time. When applying lubricating oil to the existing guide device, it is often inconvenient to apply lubricating oil, which often causes the test environment to be polluted, and the application operation is not easy to carry out. Utility Model Content

[0004] In view of the problems raised by the above background technology, the purpose of the present utility model is to provide an acupuncture guiding device.

[0005] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0006] An acupuncture guide device comprises a guide post and a guide ring slidably matched with the guide post;

[0007] The inner cavity of the guide ring is recessed to form a first annular oil storage ring and a second annular oil storage ring, wherein the first oil storage ring is on the upper side and the second oil storage ring is on the lower side;

[0008] The guide ring is provided with a first oil guide chamber, a second oil guide chamber and a third oil guide chamber, the upper port of the first oil guide chamber is located on the upper surface of the guide ring, the lower port of the first oil guide chamber is connected to the top of the second oil storage ring, the upper port of the second oil guide chamber is connected to the bottom of the first oil storage ring, the lower port of the second oil guide chamber is connected to the top of the second oil storage ring, the upper port of the third oil guide chamber is connected to the bottom of the second oil storage ring, the lower port of the third oil guide chamber is connected to the lower surface of the guide ring, and when lubrication is required, the lower port of the third oil guide chamber is in a closed state.

[0009] It is further defined that the first oil guide chamber and the third oil guide chamber are coaxially distributed, and the first oil guide chamber and the second oil guide chamber are 180° apart with respect to the axis of the guide ring. Such a structural design enables the first oil guide chamber, the second oil guide chamber and the third oil guide chamber to be staggeredly distributed, and the lubricating oil entering from the first oil guide chamber can enter the second oil guide chamber only after flowing along the first oil storage ring, and the lubricating oil entering from the second oil guide chamber can enter the third oil guide chamber only after flowing along the second oil storage ring. The above structure forcibly stipulates the flow path of the lubricating oil, so that the lubricating oil can flow around the guide column, thereby expanding the distribution range of the lubricating oil, strengthening the coating on the circumferential direction of the guide column, and also enhancing the utilization rate of the oil storage space.

[0010] It is further defined that an oil outlet nozzle is provided at a position on the lower surface of the guide ring corresponding to the lower port of the third oil guide chamber. With such a structural design, when the lubricating oil in the first oil storage ring and the second oil storage ring needs to be drained out, the outward extension of the oil outlet nozzle provides an oil receiving point, which is convenient for the container to receive the oil.

[0011] It is further defined that the upper port of the first oil guide cavity is connected to the first oil plug, and the oil outlet nozzle is connected to the second oil plug. With such a structural design, the first oil plug and the second oil plug are used for blocking to prevent direct leakage of the lubricating oil, which does not achieve a good lubrication effect.

[0012] It is further defined that the guide ring is threadedly connected to the pressure ring, and the pressure ring and the guide ring clamp a carrier plate for installing the puncture needles. With such a structural design, the pressure ring is pressed down after being screwed together to fix the carrier plate.

[0013] It is further defined that the guide ring is provided with a threaded section, a plug-in section and a limiting section with increasing diameters from top to bottom, the pressure ring is provided with a threaded cavity cooperating with the threaded section and a accommodating cavity with a diameter larger than that of the plug-in section, the carrier plate cooperates with the plug-in section, the pressure ring is threadedly connected to the threaded section and presses down the carrier plate, and the limiting section is used to support the carrier plate. With such a structural design, the pressure ring is threadedly connected to the threaded section and then presses down the carrier plate, and the accommodating cavity prevents the pressure ring from interfering with the plug-in section when it moves downward.

[0014] The beneficial effects of the utility model are as follows: the lubricating oil is filled between the inner cavity of the guide ring and the outer ring of the guide column, and the guide ring moves up and down, and the lubricating oil can be automatically applied to the circumferential surface of the guide column. The entire lubrication operation is simple and quick, and can effectively avoid pollution of the test environment caused by manual application. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0028] like Figure 1-4 As shown, an acupuncture guide device of the utility model comprises a guide column 1 and a guide ring 2 which is slidably matched with the guide column 1;

[0029] The inner cavity of the guide ring 2 is recessed to form a first annular oil storage ring 24 and a second oil storage ring 25, wherein the first oil storage ring 24 is on the top and the second oil storage ring 25 is on the bottom.

[0030] The guide ring 2 is provided with a first oil guide chamber 26, a second oil guide chamber 27 and a third oil guide chamber 28. The upper port of the first oil guide chamber 26 is located on the upper surface of the guide ring 2, the lower port of the first oil guide chamber 26 is connected to the top of the second oil storage ring 25, the upper port of the second oil guide chamber 27 is connected to the bottom of the first oil storage ring 24, the lower port of the second oil guide chamber 27 is connected to the top of the second oil storage ring 25, the upper port of the third oil guide chamber 28 is connected to the bottom of the second oil storage ring 25, the lower port of the third oil guide chamber 28 is connected to the lower surface of the guide ring 2, and when lubrication is required, the lower port of the third oil guide chamber 28 is in a closed state.

[0031] In this embodiment:

[0032] Before lubrication, the guide ring 2 should be at a high position on the guide column 1, so that the lubricating oil can fall and flow through a larger length range of the guide column 1;

[0033] The lubricating oil is injected through the upper port of the first oil guide cavity 26, and enters the first oil storage ring 24 through the first oil guide cavity 26. The annular cavity structure of the first oil storage ring 24 allows the lubricating oil to be distributed around the circumference of the guide column 1. After the lubricating oil fills the first oil storage ring 24, it enters the second oil storage ring 25 through the second oil guide cavity 27. The lubricating oil is distributed around the circumference of the guide column 1 again. The lower port of the third oil guide cavity 28 is closed to prevent the lubricating oil from being continuously discharged downward.

[0034] At this time, the lubricating oil is filled between the inner cavity of the guide ring 2 and the outer ring of the guide column 1. The guide ring 2 moves up and down, and the lubricating oil can be automatically applied to the circumferential surface of the guide column 1. The entire lubrication operation is simple and quick, and can effectively avoid contamination of the test environment caused by manual application.

[0035] Preferably, the first oil guide chamber 26 and the third oil guide chamber 28 are coaxially distributed, and the first oil guide chamber 26 and the second oil guide chamber 27 are 180° apart with respect to the axis of the guide ring 2. Such a structural design enables the first oil guide chamber 26, the second oil guide chamber 27 and the third oil guide chamber 28 to be staggeredly distributed. The lubricating oil entering from the first oil guide chamber 26 can enter the second oil guide chamber 27 only after flowing along the first oil storage ring 24, and the lubricating oil entering from the second oil guide chamber 27 can enter the third oil guide chamber 28 only after flowing along the second oil storage ring 25. The above structure forcibly stipulates the flow path of the lubricating oil, so that the lubricating oil can flow around the guide column 1, expands the distribution range of the lubricating oil, strengthens the coating of the guide column 1 in the circumferential direction, and also strengthens the utilization rate of the oil storage space. In fact, other structural shapes that allow the lubricating oil to be distributed around the guide column 1 can also be considered according to specific circumstances.

[0036] Preferably, an oil outlet nozzle 29 is provided on the lower surface of the guide ring 2 at a position corresponding to the lower end of the third oil guide cavity 28. With this structural design, when the lubricating oil in the first oil storage ring 24 and the second oil storage ring 25 needs to be drained, the outward extension of the oil outlet nozzle 29 provides an oil receiving point, which is convenient for the container to receive the oil. In fact, other oil outlet structures can also be considered according to specific circumstances.

[0037] Preferably, the upper port of the first oil guide cavity 26 is connected to the first oil plug 5, and the oil outlet nozzle 29 is connected to the second oil plug 6. In this structural design, the first oil plug 5 and the second oil plug 6 are used for blocking to prevent the lubricating oil from leaking directly, which does not achieve a good lubrication effect. In fact, other closed structures can also be considered according to specific circumstances.

[0038] Preferably, the guide ring 2 is threadedly connected to the pressure ring 3, and the pressure ring 3 and the guide ring 2 clamp the carrier plate 4 for installing the needles. In this structural design, the pressure ring 3 is pressed down after being screwed together to fix the carrier plate 4. In fact, other structural shapes for clamping the carrier plate 4 can also be considered according to specific circumstances.

[0039] Preferably, the guide ring 2 is provided with a threaded section 23, a plug section 22 and a limit section 21 with increasing diameters from top to bottom, the pressure ring 3 is provided with a threaded cavity 31 matched with the threaded section 23 and a receiving cavity 32 with a diameter larger than the plug section 22, the carrier plate 4 is matched with the plug section 22, the pressure ring 3 is threadedly connected with the threaded section 23 and presses down the carrier plate 4, such a structural design, the pressure ring 3 is threadedly connected with the threaded section 23 and presses down the carrier plate 4, the receiving cavity 32 prevents the pressure ring 3 from interfering with the plug section 22 when it moves down, and the limit section 21 is used to receive the carrier plate 4. In fact, other structural shapes of the pressure ring 3 and the guide ring 2 can also be considered according to specific circumstances.

[0040] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
