Description

Technical Field

[0001] This utility model relates to the field of charging cable technology, and in particular to a cold-resistant cable anti-freezing protection structure. Background Technology

[0002] Charging piles, also known as electric vehicle charging stations or electric vehicle power supply equipment, are devices that provide electrical energy to electric vehicles, enabling them to store enough electricity to support their operation. Charging piles are divided into indoor and outdoor types. Outdoor charging piles refer to electric vehicle charging facilities installed in outdoor public places, mainly used to provide charging services for electric vehicles used outdoors.

[0003] Current outdoor charging stations suffer from cold temperatures during winter, causing cables to harden, age, or even break under prolonged low temperatures. To address this issue, we propose a cold-resistant cable anti-freeze protection structure. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a cold-resistant cable anti-freezing protection structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cold-resistant cable antifreeze protection structure includes a charging gun, a connecting cable connected to the end of the charging gun, and an antifreeze mechanism sleeved on the surface of the connecting cable. The outer surface of the antifreeze mechanism is wrapped with heat-insulating tape, and the two ends of the heat-insulating tape are fitted with limiting mechanisms. A cleaning mechanism is adsorbed on the side of the limiting mechanism.

[0007] Preferably, the antifreeze mechanism includes a snap-fit ​​sleeve, which is snapped onto the surface of the charging gun. An insulating cotton sleeve is glued to the inner wall of the snap-fit ​​sleeve, and an insulating aluminum foil pad is glued to the inner wall of the insulating cotton sleeve. The snap-fit ​​sleeve allows the insulating cotton sleeve and the insulating aluminum foil pad to be easily snapped onto the surface of the connecting cable.

[0008] Preferably, the limiting mechanism includes a compression sleeve, and the two ends of the thermal insulation strap are engaged with the compression sleeve. Both ends of the compression sleeve are fixedly connected to a mounting plate. The mounting plate is equipped with mounting bolts. The compression sleeve can conveniently engage the limiting thermal insulation strap and the end of the antifreeze mechanism.

[0009] Preferably, the inner wall of the extrusion sleeve is bonded with an anti-slip pad, and the surface of the anti-slip pad is provided with anti-slip texture, which can increase the friction on the inner side of the extrusion sleeve.

[0010] Preferably, the cleaning mechanism includes a movable ring, the surface of the thermal insulation strap is fitted with the movable ring, and the inner wall of the movable ring is glued with a cleaning scraper ring. The cleaning scraper ring glued to the inner wall of the movable ring can be used to easily clean the surface of the thermal insulation strap.

[0011] Preferably, the cross-section of the movable ring is circular, and magnetic rings are glued to both sides of the movable ring. By making the cross-section of the movable ring circular, it can be easily fitted onto the surface of the thermal insulation strap.

[0012] Preferably, a pull handle is fixedly connected to the surface of the movable ring, and the cross-section of the pull handle is U-shaped. The surface of the pull handle is covered with a rubber sleeve, which can easily improve the surface friction of the pull handle.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This device secures the connecting cable to the surface of the cable by engaging the insulating cotton sleeve and the heat-insulating aluminum foil pad. This provides convenient protection against freezing of the connecting cable. At the same time, the insulating tape wrapped around the surface of the engaging sleeve helps to limit its function and further improves the anti-freezing effect. The compression sleeve engages at both ends of the insulating tape and the engaging sleeve, and the installation bolts passing through the mounting plate facilitate the installation of the compression sleeve. Thus, the compression sleeve can conveniently limit the installation of the insulating tape and the engaging sleeve.

[0015] 2. This device increases the friction on the inner side of the extrusion sleeve by using an anti-slip pad bonded to the inner wall of the extrusion sleeve, and protects the surface of the insulation strap end. At the same time, by pulling the handle, the moving ring can move the cleaning scraper along the surface of the insulation strap, making it convenient to clean the surface of the insulation strap during use and improving the service life of the insulation strap. In addition, the moving ring drives the magnetic ring to be attracted to the extrusion sleeve, which facilitates the function of limiting the moving ring. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-4 A cold-resistant cable antifreeze protection structure includes a charging gun 1, a connecting cable 2 connected to the end of the charging gun 1, and an antifreeze mechanism 3 sleeved on the surface of the connecting cable 2. An insulation strap 4 is wrapped around the outer surface of the antifreeze mechanism 3, and a limiting mechanism 5 is sleeved on both ends of the insulation strap 4. The limiting mechanism 5 can conveniently limit the function of the insulation strap 4 and the two ends of the antifreeze mechanism 3. A cleaning mechanism 6 is adsorbed on the side of the limiting mechanism 5.

[0027] Furthermore, refer to Figure 1 and Figure 2 It can be seen that the antifreeze mechanism 3 includes a snap-fit ​​sleeve 31. The snap-fit ​​sleeve 31 is snapped onto the surface of the charging gun 1, and the inner wall of the snap-fit ​​sleeve 31 is glued with an insulation cotton sleeve 32. The inner wall of the insulation cotton sleeve 32 is glued with a heat-insulating aluminum foil pad 33. By snapping the snap-fit ​​sleeve 31 onto the surface of the connecting cable 2, the insulation cotton sleeve 32 and the heat-insulating aluminum foil pad 33 can keep the surface of the connecting cable 2 warm and prevent freezing.

[0028] Furthermore, refer to Figure 2 and Figure 3 It can be seen that the limiting mechanism 5 includes a compression sleeve 51, the two ends of the thermal insulation strap 4 are engaged with the compression sleeve 51, and the two ends of the compression sleeve 51 are fixedly connected with the mounting plate 52. The mounting plate 52 is equipped with mounting bolts 53. By passing the mounting bolts 53 through the mounting plate 52, the compression sleeve 51 can be conveniently limited.

[0029] Furthermore, refer to Figure 2 and Figure 3It can be seen that the inner wall of the extrusion sleeve 51 is bonded with an anti-slip pad 54, and the surface of the anti-slip pad 54 is provided with anti-slip texture. The anti-slip pad 54 can increase the stability of the extrusion sleeve 51 in locking and limiting.

[0030] Furthermore, refer to Figure 2 and Figure 4 It can be seen that the cleaning mechanism 6 includes a movable ring 61. The movable ring 61 is fitted on the surface of the insulation strap 4, and a cleaning scraper 63 is glued to the inner wall of the movable ring 61. The cleaning scraper 63 is driven by the movable ring 61 to slide along the surface of the insulation strap 4, which can facilitate the cleaning of the surface of the insulation strap 4.

[0031] Furthermore, refer to Figure 2 and Figure 4 It can be seen that the cross-section of the moving ring 61 is set as a ring shape, and both sides of the moving ring 61 are glued with magnetic rings 62. The magnetic rings 62 and the extrusion sleeve 51 are attracted to each other, which can facilitate the function of limiting the moving ring 61.

[0032] Furthermore, refer to Figure 2 and Figure 4 It can be seen that a pull handle 64 is fixedly connected to the surface of the moving ring 61, and the cross-section of the pull handle 64 is set in a U-shape. The surface of the pull handle 64 is covered with a rubber sleeve. By setting the cross-section of the pull handle 64 in a U-shape, the moving ring 61 can be easily pulled to slide along the surface of the thermal insulation strap 4.

[0033] Working principle: When the charging gun 1 is in use, according to the attached... Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4 By engaging the insulating cotton sleeve 32 and the heat-insulating aluminum foil pad 33 with the snap-fit ​​sleeve 31, the insulating strap 4 is wrapped around the surface of the snap-fit ​​sleeve 31, and the moving ring 61 and the cleaning scraper ring 63 are fitted onto the surface of the insulating strap 4. At the same time, the two sets of compression sleeves 51 are engaged with the anti-slip rubber pads 54 at both ends of the insulating strap 4, so that the mounting bolts 53 can pass through the mounting plate 52 to limit the installation of the compression sleeves 51. The moving ring 61 drives the magnetic ring 62 to be attracted to the compression sleeve 51, which can limit the function of the moving ring 61. When the surface of the insulating strap 4 needs to be cleaned, the pull handle 64 is pulled, which can make the moving ring 61 drive the magnetic ring 62 away from the compression sleeve 51, so that the moving ring 61 can drive the cleaning scraper ring 63 to clean the surface of the insulating strap 4.
