DETAILED DESCRIPTION
[0025] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0026] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.
[0027] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.
[0028] One of the preferred embodiments of the present application is as follows: Figures 1 to 7 As shown, a refrigeration accessory anti-theft cap includes an inner ring 5, an outer ring 3, a stopper 6 and an unlocking member 2. The inner ring 5 is detachably mounted on the refrigeration accessory, and the outer ring 3 is limitedly sleeved on the inner ring 5 through the stopper 6 and can rotate relatively. It should be known that the inner ring 5 can be installed on the refrigeration accessory to protect it, and when the inner ring 5 needs to be removed, the inner ring 5 needs to be operated. The outer ring 3 is sleeved on the inner ring 5 and can rotate, so when the outer ring 3 is operated (rotated), the inner ring 5 is stationary, thereby realizing an anti-theft function.
[0029] It should be noted that the refrigeration accessories here are described by taking the air conditioning valve core 1 as an example. Of course, in the following embodiments, the air conditioning valve core 1 is used as an example for description.
[0030] like Figure 1As shown, when disassembling the anti-theft cap, the unlocking member 2 and the inner ring 5 can be matched, and then the unlocking member 2 can be driven to drive the inner ring 5 to separate from the air conditioning valve core 1, so that the anti-theft cap can be disassembled, which is simple and convenient. In other words, when non-professionals operate (i.e., there is no unlocking member 2), due to the protective effect of the outer ring 3, the installed inner ring 5 cannot be disassembled from the air conditioning valve core 1, which can greatly improve its safety; at the same time, due to the setting of the unlocking member 2, the subsequent disassembly is also very convenient and fast.
[0031] The present application does not limit the specific structure of the limiter 6, and only provides a specific structure for reference below:
[0032] like Figure 4 As shown, corresponding clamping groove 1 9 and clamping groove 2 10 are arranged on the outside of the inner ring 5 and the inside of the outer ring 3; the limiter 6 includes a clamping spring 601, and the clamping spring 601 cooperates with both the clamping groove 1 9 and the clamping groove 2 10. Specifically, the rotational cooperation mode of the outer ring 3 and the inner ring 5 is: the clamping spring 601 is clamped in the clamping groove 1 9 and the clamping groove 2 10, so that the outer ring 3 and the inner ring 5 can be combined under the action of the clamping spring 601, and then the two are locked in the axial position, that is, the outer ring 3 cannot move along the axial direction of the inner ring 5, but the outer ring 3 and the inner ring 5 can rotate relative to each other.
[0033] Furthermore, in order to improve the convenience of installation between the outer ring 3 and the inner ring 5, as Figure 5 As shown, the retaining spring 601 includes a circular arc segment 6011 and a raised segment 6012 connected to each other. The circular arc segment 6011 cooperates with the first retaining slot 9 , and the raised segment 6012 cooperates with both the first retaining slot 9 and the second retaining slot 10 .
[0034] It can be understood that the installation method of the outer ring 3 and the inner ring 5 is as follows: first, the arc segment 6011 is sleeved in the slot 1 9 outside the inner ring 5, and then the inner ring 5 is inserted into the outer ring 3. Due to the squeezing effect of the outer ring 3, the raised segment 6012 will be bent and deformed and snap into the slot 1 9. When the clamping spring 601 moves to correspond to the slot 2 10, the raised segment 6012 will lose its limiting effect and then elastically reset, that is, the raised segment 6012 will restore its deformation and also snap into the slot 2 10, thereby realizing the outer ring 3 being rotatably sleeved on the inner ring 5. It can be seen that during installation, only the raised segment 6012 is elastically deformed, rather than the entire clamping spring 601, that is, only part of the clamping spring 601 is deformed, which greatly improves the convenience of installation between the two.
[0035] As a further description of the above embodiment: Figure 5As shown, the arc segment 6011 and the raised segment 6012 are formed in one piece. For example, an elastic metal rod is first bent into the arc segment 6011 , and then the end of the arc segment 6011 is bent outward to form the raised segment 6012 .
[0036] like Figure 5 As shown, the raised segments 6012 are preferably used in pairs, that is, the raised segments 6012 are respectively located at the two ends of the arc segment 6011, so that there are two raised segments 6012 to engage and limit the outer ring 3 and the inner ring 5, which effectively ensures the relative position stability between the outer ring 3 and the inner ring 5, and also enhances the overall structural strength of the product.
[0037] One of the embodiments of the present application is as follows: Figure 2 and Figure 3 As shown, the inner ring 5 and the air conditioning valve core 1 are installed in such a way that the two are matched with each other through threads. When installing the anti-theft cap, the inner ring 5 is driven to rotate in a spiral by the unlocking member 2 until it abuts against the air conditioning valve core 1. When removing the anti-theft cap, similarly, the inner ring 5 is driven to rotate in a reverse spiral by the unlocking member 2 to separate the inner ring 5 from the air conditioning valve core 1.
[0038] Of course, in order to improve the sealing performance of the anti-theft cap after installation, a sealing ring 7 is provided inside the inner ring 5. When the anti-theft cap is installed, that is, after the inner ring 5 is tightened on the air conditioning valve core 1, the sealing ring 7 is matched with the inner ring 5 and the air conditioning valve core 1, thereby achieving the sealing performance of the air conditioning valve core 1 and preventing air leakage.
[0039] In this embodiment, Figure 2 and Figure 4 As shown, the inner ring 5 and the unlocking member 2 cooperate in the following manner: an unlocking groove 8 is provided at one end of the inner ring 5, and an unlocking block 4 is provided at one end of the unlocking member 2. It should be known that the unlocking member 2 and the inner ring 5 are plugged and matched with each other through the unlocking block 4 and the unlocking groove 8. In other words, when the inner ring 5 needs to be rotated, the unlocking block 4 on the unlocking member 2 is inserted into the unlocking groove 8 on the inner ring 5, and the inner ring 5 can be driven to rotate through the unlocking block 4.
[0040] Of course, the unlocking slot 8 and the unlocking block 4 have various shapes and structures, but they should be non-circular structures, otherwise they will rotate relative to each other. On the other hand, an "uncommon" structure should also be adopted. If the unlocking slot 8 is a long strip structure, it is easy to remove the anti-theft cap with a commonly used screwdriver tool, which is less secure. Figure 7 As shown in (a), it can adopt a cam structure, such as Figure 7As shown in (b), it can adopt a regular hexagonal structure. Of course, other shapes can also be adopted, such as triangles, trapezoids, etc., that is, some shapes and structures that are not available in commonly used tools in life.
[0041] In this embodiment, in order to further improve the safety performance of the anti-theft cap, Figure 4 As shown, the end of the outer ring 3 is a closed structure, that is, the outer ring 3 covers the entire inner ring 5, so that the protection effect of the inner ring 5 is better, but it cannot affect the plug-in fit between the unlocking piece 2 and the inner ring 5. Therefore, a through groove 11 matching the unlocking block 4 is provided at the end of the outer ring 3, that is, the shape of the through groove 11 and the unlocking block 4 corresponds to each other, and then when the anti-theft cap is disassembled, the unlocking block 4 can pass through the through groove 11 (outer ring 3) and then cooperate with the inner ring 5 inside.
[0042] The working principle of the utility model is:
[0043] When installing the anti-theft cap: first insert the unlocking block 4 of the unlocking member 2 from the through groove 11 of the outer ring 3, so that the unlocking block 4 is plugged into the unlocking groove 8 on the inner ring 5, and then the inner ring 5 is driven by the unlocking member 2 to rotate in a spiral, so that the inner ring 5 is screwed and tightened on the air conditioning valve core 1, and finally the unlocking member 2 is pulled out, and the outer ring 3 is sleeved on the inner ring 5 and can rotate, so when the outer ring 3 is (rotated), the inner ring 5 is stationary, thereby realizing an anti-theft function. When disassembling the anti-theft cap, the same is true, that is, first the unlocking block 4 is plugged into the unlocking groove 8, and then the inner ring 5 is driven by the unlocking member 2 to rotate in the opposite direction until the inner ring 5 is separated from the air conditioning valve core 1.
[0044] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought.
