Description

Technical Field

[0001] The utility model relates to an electronic candle lamp, and more specifically, to an electronic candle lamp for tombs. Technical Background

[0002] To cope with complex weather conditions, existing electronic candle lamps for tombs often require them to be placed in a sealed transparent container. For example, patent application number 201020286179.9, filed with the State Intellectual Property Office of China on August 5, 2010, describes a solar-powered sacrificial lamp comprising an electronic candle having a sealed outer shell with an outer wall patterned to reflect the sacrificial content. The outer shell comprises a lamp cover and a transparent lamp housing. A solar panel is located on top of the lamp cover. The electronic candle houses a control circuit board and a rechargeable battery. The solar panel is electrically connected to the control circuit board, which is in turn electrically connected to the rechargeable battery. The output of the control circuit board is connected to a light-emitting diode (LED). Depending on the usage scenario, the size and height of the transparent container vary. To meet the individual needs of different customers, the connecting rod used to hang the candle lamp has a variety of lengths and specifications, which increases logistics costs for subsequent packaging, storage, and transportation. Summary of the Invention

[0003] In order to overcome the above defects, the technical problem that the present invention needs to solve is: to provide an electronic candle lamp for tombs that can change the actual length of the connecting rod according to different needs, thereby significantly reducing the logistics costs of the electronic candle lamp for tombs in subsequent packaging, storage and transportation.

[0004] The technical solution adopted by the utility model to solve its technical problems is: an electronic candle lamp for tombs, which includes a connecting rod, one end of the connecting rod is connected to a power supply device, and the other end of the connecting rod is connected to the candle lamp, the connecting rod includes an outer connecting rod and an inner connecting rod, the inner connecting rod is sleeved in a hollow cavity of the outer connecting rod, the cavity of the outer connecting rod includes an inserting cavity that is snap-connected to the inner connecting rod and a positive cavity and a negative cavity that are inserted with a first conductor and extend axially, the outer side surface of the inner connecting rod at the position of the positive cavity and the negative cavity is provided with an axially extending groove, a conductor is provided in the groove, and a circuit position touch switch is provided between the first conductor and the conductor. This technical solution utilizes the connection between the outer rod and the inner rod to realize the retractable length of the connecting rod, unifying multiple specifications within 2 times the length of the outer rod into one specification, and at the same time reducing the size and variety of the packaging box, thereby greatly reducing the subsequent logistics costs of packaging, storage, transportation, etc.; the connection between the outer rod and the inner rod is achieved by a snap connection, the purpose of which is to enable the outer rod and the inner rod to be reliably positioned at the length required by the customer; a positive electrode cavity and a negative electrode cavity in which a first conductor is inserted are provided in the outer rod, and grooves with conductors are respectively provided at the positions corresponding to the positive electrode cavity and the negative electrode cavity on the inner rod, the purpose of which is to arrange the power supply circuit constituting the candle lamp in the two channels of the connecting rod, which can not only fully utilize the function of the connecting rod, simplify the structural layout of the power supply circuit, and reduce manufacturing costs, but also physically isolate the positive and negative circuits in the power supply circuit, thereby ensuring that the entire power supply circuit will not have unexpected conditions during operation, thereby improving the reliability of the product. As the name suggests, the circuit position touch switch determines the on / off state of the circuit based on the relative positions of the relevant parts of the circuit switch. The purpose of setting the circuit position touch switch between the first conductor and the conductor is to use the relative positions of the connecting outer rod and the connecting inner rod to determine the relative positions of the first conductor and the conductor, and then control the on / off state of the entire power supply circuit. In this way, the entire power supply circuit can be cut off at the desired position, simplifying the consumer's operation process and ensuring the reliability of power off.

[0005] As a further technical solution, the groove comprises a U-shaped conductive groove, the conductor comprises a second conductor and a third conductor, the second conductor and the third conductor are arranged side by side and abut against each other in the U-shaped conductive groove, the U-shaped conductive groove of the connecting inner rod near the power supply device or the candle lamp is provided with a recess, the recess is provided with a rotatable and conductive rolling element, the second conductor passes through the recess and extends outward, the end of the third conductor facing one end of the recess is located outside the recess, the outer periphery of the second conductor located at the recess is coated with an insulating material, the closest distance between the outer surfaces of the first and second conductors is greater than the diameter of the rolling element, and the closest distance between the outer surfaces of the first and third conductors is less than the diameter of the rolling element, the connecting outer rod is provided with a through hole at the position of the rolling element that matches the rolling element, and the circuit position touch switch comprises the first conductor, the second conductor, the third conductor, and the rolling element. The groove can be a square groove or a special-shaped groove. The present technical solution adopts a U-shaped conductive groove, which facilitates the abutment assembly and snap connection of the second and third conductors. The pit is an arc-shaped pit, which facilitates the rolling of the rolling body. The pit is set at the position of the connecting inner rod close to the power supply device or the candle lamp. Its purpose is to ensure that the circuit position touch switch is in the power-off state when the connecting inner rod is flush with the connecting outer rod at the same end. The end of the third conductor facing one end of the pit is located on the outside of the pit. The outer peripheral side of the second conductor located in the pit is coated with an insulating material. The insulating material can isolate the electrical connection between the second conductor and the rolling body. The closest distance between the outer surfaces of the first conductor and the second conductor is greater than the diameter of the rolling body, which can ensure the reliability of the circuit position touch switch being powered on. The closest distance between the outer surfaces of the first conductor and the third conductor is less than the diameter of the rolling body, which can ensure the reliability of the circuit position touch switch being powered on. The connecting outer rod is provided with a through hole at the position of the rolling body, which can facilitate the assembly of the rolling body and provide space for the elastic deformation of the first conductor.

[0006] As a further technical solution, the outer connecting rod is connected to the power supply device, and the inner connecting rod is connected to the candle lamp. Of course, it is also possible to connect the outer connecting rod to the candle lamp and the inner connecting rod to the power supply device, but this technical solution is conducive to the layout and configuration of the various parts of the tomb electronic candle lamp and facilitates assembly, and also conforms to people's aesthetic taste.

[0007] As a further technical solution, the positive and negative electrode cavities are located on opposite sides of the inner connecting rod. The other two opposite outer sides of the inner connecting rod are each provided with a guide groove. A first stopper is provided on the end of the guide groove proximate to the power supply device. The outer connecting rod is provided with a guide rib that matches the guide groove at the location of the guide groove. A second stopper is provided on the end of the guide rib proximate to the candle lamp. The provision of the first and second stoppers prevents the outer and inner connecting rods from unexpectedly disengaging during stretching.

[0008] As a further technical solution, the open end of the U-shaped conductive groove is also provided with an axially extending arcuate groove, and the two side walls of the arcuate groove are evenly distributed axially with multiple protrusions that match the steel balls. This facilitates the reliable positioning of the connecting rod and the connecting rod to the required length by the customer.

[0009] As a further technical solution, the first conductor is an elastic metal sheet.

[0010] As a further technical solution, the second conductor is a metal wire, and the insulating material is insulating varnish.
