Description

Technical Field

[0001] The utility model relates to the field of hinges, in particular to an L-shaped wire-passing hinge capable of supplying power. Background Art

[0002] Currently, all electronic locks on door panels on the market adopt two power supply modes: one is dry battery and the other is lithium battery. There is a risk of power outage at any time during use. At the very least, the user cannot return home (even if the lock factory is equipped with a mechanical key, power supply from a power bank cannot solve the need for electronic locks to be powered at any time), which brings a bad experience to customers. At worst, the poor fire resistance of the battery brings safety hazards. The weak power supply of electronic locks limits the electronic device as a security carrier and cannot be equipped with too many other security electronic devices, such as smoke sensors, fire alarms, expulsion alarms and other functions on the door panels, which does not meet people's safety needs. The weak power supply of electronic locks also leads to poor network signals and slow transmission speeds, making it difficult to truly realize the needs of smart furniture networking. Utility Model Content

[0003] The purpose of the utility model is to provide a door hinge with a door leaf power supply line, so as to solve the problems raised in the above background technology.

[0004] The technical solution adopted by the present invention is: an L-shaped wire-passing hinge with power supply, comprising a first hinge blade, a second hinge blade and a hollow rotating shaft, the first hinge blade and the second hinge blade both having a hinge portion and a mounting portion, the hinge portion being arranged on one side of the mounting portion, the length of the mounting portion being longer than the length of the hinge portion, a plurality of mounting holes connected to a door leaf or a door frame being provided in the mounting portion, the hinge portion being provided with a threading hole at a position close to the end portion, the hinge portion of the first hinge blade being sleeved on the top of the hollow rotating shaft, the threading hole thereof being higher than the top of the hollow rotating shaft, the hinge portion of the second hinge blade being sleeved on the bottom of the hollow rotating shaft, the threading hole thereof being lower than the bottom portion of the hollow rotating shaft.

[0005] Furthermore, a blocking steel ring is sleeved on the outer side of the hollow rotating shaft, and the blocking steel ring can enable the hinge parts of the first hinge blade and the second hinge blade to be sleeved into the corresponding positions of the hollow rotating shaft.

[0006] Furthermore, the ends of the hinged parts of the first hinge blade and the second hinge blade are both provided with sealing covers, which can prevent foreign matter from entering the interior of the hollow shaft and affecting normal use.

[0007] Compared with the prior art, the beneficial effects of the present invention are as follows: the power-supply L-shaped wire-through hinge is generally installed in the middle position between the door leaf and the door frame. The power cord enters the hollow shaft through the wire-through hole on the side of the first hinge blade and extends out from the wire-through hole on the second hinge blade, completing a wire-through action to provide stable and continuous power for the electronic equipment on the door body, thereby solving the existing problems raised in the background technology, and thus there will be no phenomenon that the electronic equipment has poor network signals and slow transmission speeds due to weak power supply, which makes it difficult to truly realize the needs of smart furniture networking.

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] like Figures 1 to 5The invention relates to an L-shaped wire-passing hinge with power supply, comprising a first hinge blade 10, a second hinge blade 20 and a hollow shaft 30. The first hinge blade 10 and the second hinge blade 20 both have a hinge portion 11 and a mounting portion 12. The hinge portion 11 is provided on one side of the mounting portion 12. The length of the mounting portion 12 is longer than the length of the hinge portion 11. The mounting portion 12 is provided with a plurality of mounting holes 13 connected to the door leaf or door frame. The hinge portion 11 is provided with a threading hole 14 at a position near the end. The hinge portion 11 of the first hinge blade 10 is sleeved on the top of the hollow shaft 30, and its threading hole 14 is higher than the top of the hollow shaft 30. The hinge portion 11 of the second hinge blade 20 is sleeved on the bottom of the hollow shaft 30, and its threading hole 14 is lower than the bottom of the hollow shaft 30.

[0016] During use, when the power cord 15 supplying power between the door frame and the door leaf needs to pass through the hinge, the power cord 11 first enters the interior of the hollow rotating shaft 30 from the wire hole 14 of the first hinge blade 10, and then extends to the wire hole 14 of the second hinge blade 20 and then passes outward to complete the wire passing, so that the hinge can realize the hinge connection between the door frame and the door leaf while also allowing the power cord to pass through.

[0017] The outer side of the hollow rotating shaft 30 is sleeved with a blocking steel ring 31 , and the blocking steel ring 31 enables the hinge parts 11 of the first hinge blade 10 and the second hinge blade 20 to be sleeved into corresponding positions of the hollow rotating shaft 30 .

[0018] The ends of the hinged portions 11 of the first hinge blade 10 and the second hinge blade 20 are both provided with sealing covers 16 , which can prevent foreign matter from entering the interior of the hollow shaft 30 and affecting normal use.

[0019] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
