Description

Technical Field

[0001] This utility model relates to the field of electrical engineering technology, and in particular to a plug protective sleeve. Background Technology

[0002] Traditional plugs often have exposed metal prongs due to improper insertion or removal, which can lead to electric shocks to children, the elderly, and other vulnerable groups. In humid environments, they can also cause short circuits and fires, and related safety accidents occur frequently. As many countries and my country have introduced requirements for plug insulation protection in their national standards, plug protective sleeves have emerged to avoid electrical risks and ensure safe use.

[0003] In the existing technology, the existing double-ended plug protective sleeves usually use a fixed size that can only fit specific plug models, resulting in poor versatility. Users need to stock multiple specifications of products to meet the protection needs of different double-ended plugs.

[0004] Therefore, a plug protective sleeve is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a plug protective sleeve that can solve the problems of poor universality and unstable fixation of existing plugs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a plug protective sleeve, comprising two ABS protective sleeves arranged horizontally, an adjustment mechanism movably connected to the outer side of each ABS protective sleeve, and an adaptive component movably connected to the inner side of each ABS protective sleeve. The adjustment mechanism includes a support slider, which is fixedly connected to the top and bottom of the ABS protective sleeve. A support plate is slidably connected to the outer side of the support slider. The two ABS protective sleeves are symmetrically arranged about the support plate. An adjustment component is movably connected to the top of each of the two ABS protective sleeves.

[0007] Preferably, the adaptive component includes two arc-shaped fixing rods, which are respectively disposed on the inner side of the ABS protective sleeve, and the two arc-shaped fixing rods are arranged symmetrically from top to bottom.

[0008] Preferably, the two arc-shaped fixing rods are fixedly connected to supporting slide rods on opposite sides, and the two sets of supporting slide rods are slidably connected to the top and bottom of the ABS protective sleeve, respectively, and penetrate through the ABS protective sleeve.

[0009] Preferably, a compression spring is sleeved on the outer side of the support slide rod, and the compression spring is located on the section of the support slide rod located inside the ABS protective sleeve.

[0010] Preferably, the adjustment component includes two linkage blocks, which are respectively fixedly connected to the top of the ABS protective sleeve, and a threaded sleeve is fixedly connected to the inner side of the linkage block.

[0011] Preferably, the inner side of the threaded sleeve is threaded with a bidirectional adjusting screw, which is rotatably connected to the rear side of the support plate.

[0012] Preferably, a protective shell is fixedly connected to the rear side of the support plate, and the protective shell is disposed on the outside of the bidirectional adjusting screw.

[0013] Preferably, anti-slip pads are fixedly connected to the opposite sides of the two arc-shaped fixing rods.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This application, by setting up an adjustment mechanism, abandons the fixed size design of existing double-ended plug protective sleeves and adopts two sets of ABS protective sleeves with relatively long initial length, width and thickness. The support slider and the support plate form an equidistant sliding connection. With the help of the rear bidirectional adjustment screw driving the threaded linkage block, the two protective sleeves can slide synchronously inward and outward to flexibly adjust the spacing. This can not only adapt to different models of double-ended plugs, effectively solving the problem of poor universality of traditional products that requires users to keep multiple specifications in stock, but also achieve dust protection by the support plate fitting against the plug insertion surface after plugging. It takes into account both the flexibility of adaptation and the practicality of protection, and improves the ease of use.

[0016] 2. This application, by setting up an adaptive component, uses the ABS protective sleeve with its initial longer length and width to adapt to different models of pins of the same thickness. At the same time, the built-in symmetrical arc-shaped fixing rods solve the problem of loosening of the plug due to the extra length and width. When the pin is plugged in, it squeezes the arc surface of the arc-shaped fixing rod, causing it to move to both sides and drive the support slide rod to compress the compression spring, thereby forming an inward elastic clamping force. This achieves a stable plugging effect through elastic limiting while flexibly adapting to different pins, thus taking into account both adaptability and protective stability.

[0023] 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.

[0024] Please see Figure 1-5 The present invention provides the following technical solution:

[0025] A plug protective cover includes two ABS protective covers 1, which are horizontally arranged. An adjustment mechanism 2 is movably connected to the outer side of the ABS protective cover 1, and an adaptive component 3 is movably connected to the inner side of the ABS protective cover 1. The adjustment mechanism 2 includes a support slider 21, which is fixedly connected to the top and bottom of the ABS protective cover 1. A support plate 22 is slidably connected to the outer side of the support slider 21. The two ABS protective covers 1 are symmetrically arranged about the support plate 22. An adjustment component 23 is movably connected to the top of the two ABS protective covers 1.

[0026] In this embodiment: instead of using a fixed-size plug protective sleeve, two sets of ABS protective sleeves 1 with a relatively long initial length and width and the same thickness are used as the double-ended plug pin protection structure. The two ABS protective sleeves 1 are slidably connected to the support plate 22 at equal intervals through the support slider 21. With the help of the adjustment component 23, they can be adjusted synchronously inward or outward inside the support plate 22 through the support slider 21.

[0027] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, the adaptive component 3 includes two arc-shaped fixing rods 31, which are respectively disposed on the inner side of the ABS protective sleeve 1, and the two arc-shaped fixing rods 31 are arranged symmetrically from top to bottom.

[0028] Specifically, such as Figure 1 , Figure 2 , Figure 5As shown, two arc-shaped fixing rods 31 are fixedly connected to support slide rods 32 on opposite sides. The two sets of support slide rods 32 are slidably connected to the top and bottom of the ABS protective sleeve 1, and penetrate through the ABS protective sleeve 1.

[0029] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, a compression spring 33 is sleeved on the outer side of the support slide rod 32, and the compression spring 33 is located on a section of the support slide rod 32 located inside the ABS protective sleeve 1.

[0030] In this embodiment: because the initial length and width of the plug are relatively long and the thickness is consistent, in order to adapt to plugs of different models with the same thickness and to avoid loosening of the plug, the ABS protective sleeve 1 is provided with two sets of arc-shaped fixing rods 31 symmetrically arranged inside. The plug side located at the opening of the ABS protective sleeve 1 is arc-shaped and initially close to the center of the ABS protective sleeve 1. When the plug is plugged in, the arc surface of the arc-shaped fixing rod 31 is squeezed by the pushing force, causing the two arc-shaped fixing rods 31 to move to both sides, driving the outer support slide rod 32 to slide to the outside of the ABS protective sleeve 1 and press the compression spring 33 located in the inner section of the ABS protective sleeve 1 and sleeved on the outside of the support slide rod 32. This causes the arc-shaped fixing rod 31 to generate an inward circumferential tightening force, so as to achieve stable fastening of plugs of different models with the same thickness under the extra width and length settings, and complete the plug-in protection.

[0031] Specifically, such as Figure 3 , Figure 4 As shown, the adjustment component 23 includes two linkage blocks 2301, which are fixedly connected to the top of the ABS protective sleeve 1, and a threaded sleeve 2302 is fixedly connected to the inner side of the linkage block 2301.

[0032] Specifically, such as Figure 3 , Figure 4 As shown, the inner thread of the threaded sleeve 2302 is connected to a bidirectional adjusting screw 2303, which is rotatably connected to the rear side of the support plate 22.

[0033] In this embodiment: a bidirectional adjusting screw 2303 is provided on the rear side of the support plate 22 for rotational connection. The tops of the two ABS protective sleeves 1 are respectively threaded to the opposite sides of the threads of the bidirectional adjusting screw 2303 through the linkage block 2301 of the built-in threaded sleeve 2302. Manually turning the bidirectional adjusting screw 2303 can drive the linkage block 2301 to move inward or outward at the same time, so that the two ABS protective sleeves 1 can be adjusted inward or outward synchronously inside the support plate 22 through the support slider 21.

[0034] Specifically, such as Figure 1 , Figure 2 As shown, a protective shell 4 is fixedly connected to the rear side of the support plate 22, and the protective shell 4 is located on the outside of the bidirectional adjusting screw 2303.

[0035] Specifically, such as Figure 5 As shown, anti-slip pads 5 are fixedly connected to the opposite sides of the two arc-shaped fixing rods 31.

[0036] In this embodiment: the protective shell 4 can protect the bidirectional adjusting screw 2303 and prevent accidental injury to personnel. The anti-slip pad 5 can reduce the contact damage of the arc-shaped fixing rod 31 to the pins and increase the fastening stability.

[0037] Working Principle: Existing double-ended plug protective sleeves typically use fixed sizes that only fit specific plug models, resulting in poor versatility. Users need to stock multiple specifications to meet the protection needs of different double-ended plugs. To avoid this, fixed-size plug protective sleeves are no longer used. Instead, two sets of ABS protective sleeves 1 with relatively long initial length and width and uniform thickness are used as the double-ended plug pin protection structure. The two ABS protective sleeves 1 are no longer fixed at a fixed distance using a fixed structure, but are slidably connected to the support plate 22 at equal intervals via support sliders 21. Adjustment components 23 can be used to adjust the two... The ABS protective sleeves 1 can slide inwards or outwards simultaneously to adjust the distance between them, adapting to different models of double-ended plugs. After insertion, the support plate 22 fits against the plug surface, also providing dust protection. The main adjustment method involves a bidirectional adjusting screw 2303 rotatably connected to the rear of the support plate 22. The tops of the two ABS protective sleeves 1 are threaded to opposite sides of the bidirectional adjusting screw 2303 via a linkage block 2301 with an internal threaded sleeve 2302. When the bidirectional adjusting screw 2303 is manually turned, it drives the screws located on opposite sides of the thread. The linkage blocks 2301 on both sides move inward or outward simultaneously, thereby allowing the two ABS protective sleeves 1 to be adjusted simultaneously inward and outward within the support plate 22 via the support slider 21. Furthermore, due to their relatively long initial length, width, and consistent thickness, they can accommodate different types of pins of the same thickness. To prevent loosening during insertion, two sets of symmetrically arranged arc-shaped fixing rods 31 are provided inside the ABS protective sleeve 1. These arc-shaped fixing rods 31 are curved on the insertion side of the pin, i.e., at the opening of the ABS protective sleeve 1. Initially, the two arc-shaped fixing rods 31 are positioned close to the center of the ABS protective sleeve 1. When the pin is inserted, they move inward... The thrust and the compression of the arc surfaces of the two arc-shaped fixing rods 31 cause the two arc-shaped fixing rods 31 to move to both sides simultaneously. Under this compression, the support slide rod 32 on the outer side of the arc-shaped fixing rod 31 slides to the outside of the ABS protective sleeve 1, while pressing the compression spring 33 that is sleeved on the outer side of the support slide rod 32 and set in the inner section of the ABS protective sleeve 1. This causes the two arc-shaped fixing rods 31 to form an inward circumferential tightening force. After the corresponding length, elastic circumferential limiting is formed on both sides, achieving the effect of maintaining a stable tightening force even with extra width and length. This completes the plug protection, and in summary, it optimizes the plug protective sleeve.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
