Description
Technical Field
[0001] This utility model relates to the technical field of installation tool components, and in particular to an installation tool component for a charging pile gland. Background Technology
[0002] Charging piles function similarly to gas pumps at gas stations. They can be fixed to the ground or walls and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. They can charge various models of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles.
[0003] Among them, the application of the Gland connector in the charging pile is crucial. It is mainly used for the connection and sealing between the charging pile shell and the cable to ensure the electrical safety and protection performance of the charging pile.
[0004] However, the existing charging station header assembly structure and installation method have the following problems: 1. Inconvenient installation: Traditional cable gland assembly often requires the use of a regular wrench to tighten the nuts. In the confined space of charging stations, regular wrenches, due to their large size and inflexible shape, are difficult to maneuver within the limited space, leading to difficulties for installers and increasing installation time and labor costs. For example, in some charging stations' narrow wiring chambers, conventional wrenches cannot be easily inserted and tightened, resulting in extremely low installation efficiency for the cable glands.
[0005] 2. The locking nut of the gland head will rotate with the end of the gland head, thus preventing the gland head from locking.
[0006] Therefore, there is an urgent need for an installation tool assembly for charging pile glands that can significantly improve installation efficiency and save labor costs while locking the glands. Utility Model Content
[0007] In view of this, the technical problem to be solved by this utility model is to provide an installation tool assembly for charging pile glands, so as to solve the problems of existing charging pile glands not locking tightly, low installation efficiency, and high labor costs.
[0008] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: According to one aspect of the present invention, an installation tool assembly for a charging pile gland is provided. The charging pile includes a charging pile body and the gland, the gland including a gland end and a locking nut. The installation tool assembly includes a locking nut holder and a wrench. The locking nut holder is detachably engaged with the gap between the locking nut and the charging pile body for fixing the locking nut. The wrench includes a handle and a first connecting part. The first connecting part has a hexagonal groove and is connected to the gland end through the hexagonal groove. The handle is connected to the first connecting part.
[0009] Preferably, the cross-section of the outer peripheral wall of the locking nut is a regular hexagon, and the gap is formed between the first and second parallel edges of the locking nut and the charging pile body.
[0010] Preferably, the charging pile body includes a first groove and a second groove, the gland includes a first gland and a second gland, and the locking nut includes a first locking nut and a second locking nut. The first gland and the second gland are respectively spaced apart on the first groove and the second groove. The third and fourth parallel edges of the first locking nut have a first gap and a second gap corresponding to the side end face of the first groove. The fifth and sixth parallel edges of the second locking nut have a third gap and a fourth gap corresponding to the side end face of the second groove.
[0011] Preferably, the locking nut holder includes a first locking nut holder and a second locking nut holder, the first locking nut holder is in the shape of a "〔" and engages with the first gap and the second gap, and the second locking nut holder is in the shape of a "〔" and engages with the third gap and the fourth gap.
[0012] Preferably, the first locking nut holder and the second locking nut holder are connected as one unit through the second connecting part.
[0013] Preferably, when the first connecting portion is connected to the end of the gland, the first connecting portion covers the end of the gland.
[0014] Preferably, the assembly gap between the first connecting part and the end of the gland is 0.01 mm.
[0015] Preferably, a sealing ring and a gasket are provided between the gland and the charging pile body.
[0016] Preferably, the cross-section of the outer peripheral wall of the first connecting part is circular and connects to the socket angle of the hexagonal groove.
[0017] Preferably, the thickness of the end of the gland is a set value.
[0018] Compared with the prior art, the installation tool assembly for charging pile glands provided by this utility model has a locking nut holder. The locking nut holder can engage with the gap between the locking nut and the charging pile body and fix the locking nut. At this time, by manually turning the handle, the first connecting part is pushed to rotate, which in turn drives the end of the gland that cooperates with the first connecting part to rotate and tighten. The installation efficiency is high and the labor cost is low. Attached Figure Description

[0022] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0023] like Figures 1 to 3 As shown, Figure 1 This is a schematic diagram of the installation tool assembly for the charging pile gland provided in Embodiment 1 of the present invention, which is installed on the charging pile. Figure 2 This is a schematic diagram of an installation tool assembly for a charging pile gland that is separated from the charging pile, as provided in Embodiment 1 of this utility model. Figure 3 This is a schematic diagram of the wrench in an installation tool assembly for a charging pile gland provided in Embodiment 1 of this utility model.
[0024] In this embodiment, the charging pile includes a charging pile body 1 and a gland connector. The gland connector includes a gland connector end 31 and a locking nut 32. The installation tool assembly includes a locking nut holder 20 and a wrench 10. The locking nut holder 20 is detachably engaged with the gap between the locking nut 32 and the charging pile body 1 to fix the locking nut 32. The wrench 10 includes a handle 11 and a first connecting part 12. The first connecting part 12 has a hexagonal groove 121. The first connecting part 12 is connected to the gland connector end 31 through the hexagonal groove 121. The handle 11 is connected to the first connecting part 12.
[0025] In this embodiment, the side end face of the charging pile body 1 is provided with two spaced-apart first grooves 41 and second grooves 42. The cross-sections of the first grooves 41 and second grooves 42 are "[" shaped, and the side openings of the first grooves 41 and second grooves 42 face downwards. The gland includes a first gland and a second gland, which are detachably installed in the first groove 41 and the second groove 42, respectively. The locking nut 32 includes a first locking nut and a second locking nut, which are threaded to the gland and located on the side of the gland near the bottom end face of the first groove 41 and the second groove 42. The cross-section of the outer peripheral wall of the first locking nut and the second locking nut is a regular hexagon. Before using the locking nut holder 20, it is necessary to adjust the parallel third and fourth edges of the first locking nut to be parallel to the two side end faces of the first groove 41 to form an equally spaced first gap and a second gap; adjust the parallel fifth and sixth edges of the second locking nut to be parallel to the two side end faces of the second groove 42 to form an equally spaced third gap 421 and a fourth gap 422.
[0026] It is understood that in this embodiment, the first and second glands have the same structure, only differing in size. Similarly, the first and second grooves also have the same structure, differing only in size.
[0027] In some embodiments, the locking nut holder 20 includes a first locking nut holder 21 and a second locking nut holder 22. The first locking nut holder 21 is shaped like a "〔" and engages with a first gap and a second gap. Specifically, the first locking nut holder 21 has a first holder body 211 shaped like a "I" and a first engaging portion 212 and a second engaging portion 213 extending vertically from both ends of the first holder body 211 in the same direction. The second locking nut holder has a second holder body 221 shaped like a "I" and a third engaging portion 222 and a fourth engaging portion 223 extending vertically from both ends of the second holder body 221 in the same direction. The first engaging portion 212 extends into the first gap and engages in the first gap, while the second engaging portion extends into the second gap and engages in the second gap. The structure and arrangement of the second locking nut holder are the same as those of the first locking nut holder, and will not be described again here.
[0028] In this embodiment, the first locking nut holder 21 and the second locking nut holder 22 are connected as one unit via the second connecting portion 23. Specifically, the first holder body 211 and the second holder body 221 are integrated into a single structure. This configuration, compared to separate first holder body 211 and second holder body 221, provides greater static friction for either of the glands that needs to be tightened, thereby preventing slippage during the tightening process between the first connecting portion 12 and the gland end 31.
[0029] In this embodiment, the gland end 31 is provided with a hexagonal nut structure. When the first connecting part 12 is engaged with the gland end 31, the first connecting part 12 covers the hexagonal nut structure of the gland end 31. Specifically, the first connecting part 12 covers the hexagonal nut structure of the gland end 31 in the thickness direction. This arrangement provides a larger contact area between the first connecting part 12 and the gland end 31, which also provides greater static friction when tightening the gland, thus preventing slippage during the tightening process.
[0030] In this embodiment, the assembly gap between the first connecting part 12 and the end of the gland 31 is 0.01 mm. This setting is also to provide greater static friction when tightening the gland, so that the first connecting part 12 and the end of the gland 31 will not slip during the tightening process.
[0031] In this embodiment, a sealing ring and a gasket are provided between the charging head and the charging pile body 1, which serve to provide waterproofing, dustproofing, and cushioning.
[0032] In this embodiment, the cross-section of the outer end face of the first connecting portion 12 is circular and connects to the socket corner of the hexagonal groove 121. That is, the cross-section of the outer end face of the first connecting portion 12 is basically the size of the circumcircle of the hexagonal groove 121. This arrangement makes the first connecting portion 12 compact in size, facilitating the tightening of the gland head in the first groove 41 and the second groove 42.
[0033] In this embodiment, the thickness of the gland tip 31 is a predetermined value. This predetermined value is determined such that the first connecting portion 12 covers every unit of the gland tip 31 in the thickness direction, thus providing a fixed maximum static friction force. Simultaneously, the torque required to tighten the gland is also within a fixed small range. Dividing the torque required to tighten the gland by the maximum static friction force provided per unit length yields the minimum thickness of the gland tip 31, which is a few unit lengths. This length is the minimum value of the predetermined value.
[0034] The assembly steps for the gland are described below: 1. Thread the cable through the gland and tighten the lock nut 32; 2. Engage the first locking nut holder 21 and the second locking nut holder 22, which are connected as one unit, in the aforementioned first to fourth gaps 422; 3. Connect the first connecting part 12 of the wrench 10 to the end 31 of the gland head through the hexagonal groove 121 and apply appropriate torque to tighten the lock nut 32; 4. Finally, install the sealing ring and gasket between the gland and the charging pile body 1 to complete the assembly. Disassembly is done in reverse order.
[0035] This utility model provides an installation tool assembly for charging pile glands. By setting a locking nut holder 20, the locking nut holder 20 can engage with the gap between the locking nut 32 and the charging pile body 1 and fix the locking nut 32. At this time, by manually turning the handle 11, the first connecting part 12 is pushed to rotate, thereby driving the gland end 31 that cooperates with the first connecting part 12 to rotate and tighten. The installation efficiency is high and the labor cost is low.
[0036] Because the first connecting part 12 has a compact structure and can provide sufficient static friction for tightening the gland, it reduces installation time and labor costs, making the installation process smoother. For example, installing a gland might have taken 5 minutes previously, but with this new structure, installation can be completed in less than 1 minute.
[0037] This invention controls the maximum static friction between the first connecting part 12 and the gland end 31 by setting the thickness value of the gland end 31. It can be understood that this maximum static friction can be consistent with the torque required to tighten the gland. Thus, when the first connecting part 12 tightens the gland end 31 to the required torque, it will slip out and will not tighten further. This achieves precise control of the tightening torque. It effectively prevents the locking nut 32 from being tightened too much or too little, reducing the incidence of leakage faults caused by a loose locking nut 32 by more than 80%.
[0038] This invention utilizes multiple different first connecting parts 12 to adapt to various models and specifications of charging pile glands, reducing the types of installation tools and lowering tool management costs. For example, a charging pile manufacturer previously needed to prepare five different wrenches; with this technology, only one or two wrenches of this invention are required.
[0039] Due to the compact design of the first connecting part 12, the wrench 10 is less likely to come into contact with the cable, reducing the risk of scratching the cable sheath, better protecting the cable insulation performance, ensuring the safe and stable operation of the charging pile, and reducing the cost of repairing faults caused by cable damage.
[0040] The preferred embodiments of the present invention have been described above with reference to the accompanying drawings, but this does not limit the scope of the present invention. Those skilled in the art can implement the present invention in various modifications without departing from its scope and essence; for example, a feature of one embodiment can be used in another embodiment to obtain yet another embodiment. Any modifications, equivalent substitutions, and improvements made within the scope of the present invention's technical concept should be within the scope of the present invention.
