Description

Technical Field

[0001] This application pertains to the field of electrical engineering, and in particular relates to a cabinet with a rail-mounted power connection mechanism. Background Technology

[0002] Common dressing tables or industrial cabinets are usually equipped with ambient lights or lighting that remain on when the drawers are opened. This function provides illumination in dark conditions and prevents accidental contact with other sharp objects during use, thus avoiding injury to the operator.

[0003] refer to Figure 1 This device combines an existing cabinet 1 and drawer 2. It mainly includes a cabinet 1 and a drawer 2 slidably connected within the cabinet 1. A conductive element 4 is installed between the cabinet 1 and drawer 2, allowing the cabinet 1 and drawer 2 to be connected to an external power source, thus powering the ambient light or ambient lighting inside drawer 2. Currently, the conductive element 4 is generally a spring wire 3. When drawer 2 is pulled out, the spring wire 3 can extend and retract to meet the power supply needs of drawer 2 in its sliding state relative to cabinet 1. Simultaneously, to maintain a compact internal wiring configuration, cable ties are typically used to secure the spring wire 3 in a designated position, leaving only the bending space for the spring wire 3.

[0004] During use, due to the fatigue life of the conductive element 4, frequent opening and closing of drawer 2 will cause the conductive element 4 to break, which will lead to the breakage of the spring wire 3, or the spring wire 3 may fall into the slide rail groove of drawer 2 and be pulled off, thus reducing the service life of the spring wire 3 and affecting the normal use of electrical components inside drawer 2. Utility Model Content

[0005] In order to improve the service life of conductive components and ensure that frequent opening and closing of drawers and cabinets does not affect the service life of conductive components, this application provides a cabinet with a guide rail power connection mechanism.

[0006] The cabinet with a guide rail power connection mechanism provided in this application adopts the following technical solution:

[0007] A cabinet with a guide rail power connection mechanism includes a cabinet body, a drawer slidably connected inside the cabinet body, and a conductive element disposed between the cabinet body and the drawer. Power is supplied between the cabinet body and the drawer through the conductive element. The conductive element includes a power transmission guide rail and a power transmission part. The power transmission guide rail is fixedly connected to the cabinet body, and the power transmission part is fixedly connected to the bottom of the drawer. The power transmission guide rail and the power transmission part are in contact connection.

[0008] By adopting the above technical solution, the cabinet effectively stores drawers, and ambient lights or lighting are installed in the drawers. The cabinet and drawers together protect the electrical components from external environmental factors such as dust, moisture, and debris. The conductive components can effectively connect the electrical components in different drawers, ensuring that all electrical components in the cabinet remain connected.

[0009] The conductive components, including the power transmission rail and the power transmission part, serve as direct transmission elements. The contact connection between the power transmission rail and the power transmission part can maintain the connection when the drawer and cabinet are pulled out and opened.

[0010] Optionally, the power transmission section is a power transmission wheel, which includes a wheel body and a mounting base on the outside of the wheel body. The mounting base is U-shaped, and the wheel body is hinged in the mounting base. The mounting base is fixedly connected to the drawer, and the wheel body is in contact with the power transmission guide rail.

[0011] By adopting the above technical solution, the power transmission wheel provides an actuator that is specifically connected to the power transmission guide rail. The mounting base that is hinged to the outside of the power transmission wheel can be fixed to the drawer, so that the electricity on the power transmission guide rail is transmitted to the drawer through the power transmission wheel. Under the weight of the drawer, the wheel body and the power transmission guide rail are always in contact, thereby ensuring the smooth flow of the circuit.

[0012] Optionally, multiple transmission wheels are provided, and the multiple transmission wheels are arranged at equal intervals along the length of the drawer.

[0013] By adopting the above technical solution, specifically, two power transmission wheels are set. The two power transmission wheels, which are equally spaced along the length of the drawer, can keep the cabinet and the drawer in contact with the power supply.

[0014] Optionally, the wheel body thickness ranges from 3.0mm to 4.0mm, the wheel body diameter ranges from 6mm to 10mm, and the mounting base thickness ranges from 0.6mm to 1.0mm.

[0016] Optionally, the power transmission section is a conductive plate, which is fixedly connected to the drawer and slidably engaged with the power transmission guide rail.

[0017] By adopting the above technical solution, a conductive plate is fixedly attached to the bottom of the drawer.

[0018] Optionally, the conductive plate includes a connecting base fixed to the drawer, with one end of the connecting base bent out to form a contact in a direction away from the drawer, and the contact being slidably connected to the power transmission rail.

[0019] By adopting the above technical solution, the conductive plate, as the execution component that specifically connects with the power transmission rail, includes a connecting base that is fixed to the drawer. One side of the connecting base is bent to form a contact point, which transmits the electricity on the power transmission rail to the drawer through the connecting base.

[0022] Optionally, two conductive elements are provided between each drawer and the cabinet, with the two conductive elements located on opposite sides of the drawer.

[0023] By adopting the above technical solution, conductive elements provide power supply connections for each drawer and cabinet.

[0024] Optionally, there are at least two connection points between the base and the drawer.

[0025] By adopting the above technical solution, the two fixing points can ensure the connection strength between the connecting base and the drawer.

[0026] Optionally, the conductive plate may be made of a highly conductive material.

[0027] By adopting the above technical solution, highly conductive materials can ensure the power supply efficiency between drawers and cabinets.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. The cabinet effectively stores drawers, with ambient lighting and ambient illumination installed inside. The cabinet and drawers together protect the electrical components from external environmental factors such as dust, moisture, and debris.

[0038] The following is in conjunction with the appendix Figure 2-5 This application will be described in further detail.

[0039] This application discloses a cabinet with a guide rail power connection mechanism.

[0040] Example 1

[0041] Reference Figure 2 and Figure 3 The cabinet with a guide rail power connection mechanism includes a cabinet body 1. Several drawers 2 are slidably connected from top to bottom inside the cabinet body 1. The cabinet body 1 is provided with a conductive element 4. The conductive element 4 includes a power transmission guide rail 41 and a power transmission part 42. The power transmission part 42 is fixedly connected to the drawer 2. The power transmission guide rail 41 is fixedly connected to the cabinet body 1. The power transmission part 42 is in contact with the power transmission guide rail 41 to supply power.

[0042] Each drawer 2 may have two sets of conductive elements 4, with the two sets of conductive elements 4 located on opposite sides of the drawer 2.

[0043] Reference Figure 2 and Figure 3 The power transmission section 42 is a power transmission wheel 421, which is rotatably connected to the bottom of the drawer 2. The outer edge of the power transmission wheel 421 is always in contact with the power transmission guide rail 41, and the power transmission wheel 421 is slidably connected to the power transmission guide rail 41.

[0044] Specifically, the power transmission wheel 421 includes a wheel body 4211, with a U-shaped mounting base 4212 on the outer side of the wheel body 4211. The wheel body 4211 is rotatably connected to the mounting base 4212. The bottom of the wheel body 4211 contacts and slides with the top of the corresponding power transmission rail 41. The current from the external power supply connected to the cabinet 1 is transmitted to the drawer 2 through the contact between the wheel body 4211 and the power transmission rail 41, thereby continuously powering the ambient light in the drawer 2. When the drawer 2 is pulled out, the wheel body 4211 slides on the power transmission rail 41, which enables continuous power supply and does not affect the service life of the conductive component 4, thus ensuring the service life of the wheel body 4211.

[0045] Of course, an installation groove 21 can also be opened at the bottom of drawer 2, and the power transmission wheel 421 can be embedded in the installation groove 21 and rotated and connected to drawer 2.

[0046] Multiple power transmission wheels 421 can be arranged at intervals along the length of drawer 2 on each side. This application takes two power transmission wheels 421 as an example for illustration. The two power transmission wheels 421 are located at the two ends of drawer 2 respectively.

[0047] The thickness of the wheel body 4211 can be between 3mm and 4mm, and in this application it can be 3.5mm, so as to ensure that the contact area between the wheel body 4211 and the power transmission rail 41 will not be welded together under high voltage.

[0048] The diameter of the wheel body 4211 ranges from 6mm to 10mm, and in this application it can be 8mm. The range of the wheel body 4211 diameter can ensure the amount of wear during the service life of the wheel body 4211, so as not to cause damage to the wheel body 4211 during its service life.

[0049] The thickness of the mounting base 4212 ranges from 0.6mm to 1.0mm, and in this application it can be 0.8mm; the wheel body 4211 is selected from 3mm to 4mm, and in this application it can be 3.5mm to ensure the support strength of the wheel body 4211.

[0050] The material of the power transmission part 42 is a highly conductive material, specifically oxygen-free copper, phosphorus deoxidized copper, or silver-copper alloy.

[0051] The implementation principle of Example 1 is as follows: the operator manually pulls out the drawer 2, and the power transmission wheel 421 located at the bottom of the drawer 2 slides on the power transmission guide rail 41 located in the cabinet 1 and always keeps in contact with the power transmission guide rail 41, thereby realizing continuous power supply, improving the service life of the conductive component 4, and ensuring that the frequent opening and closing of the drawer 2 and the cabinet 1 will not affect the service life of the conductive component 4.

[0052] Example 2

[0053] Reference Figure 4 and Figure 5 The difference between this embodiment and embodiment 1 is that the power transmission part 42 is a conductive plate 422, and the conductive plate 422 is fixedly connected to the drawer 2.

[0054] Specifically, the conductive plate 422 includes a connecting base 4221, which is fixed to the bottom of the drawer 2. One end of the connecting base 4221 is bent away from the drawer 2 to form a contact 4222, which is slidably connected to the power transmission rail 41.

[0055] Specifically, the contact 4222 is in contact with the power supply rail 41. The contact 4222 located at the bottom of the drawer 2 slides on the power supply rail 41 located inside the cabinet 1 and always maintains contact with the power supply rail 41, thereby achieving continuous power supply, improving the service life of the conductive element 4, and ensuring that the frequent opening and closing of the drawer 2 and the cabinet 1 will not affect the service life of the conductive element 4.

[0056] Multiple conductive plates 422 can be provided on each side of drawer 2 at intervals along the length of drawer 2. This application takes two conductive plates 422 as an example for illustration. The two conductive plates 422 are located at the two ends of drawer 2 respectively.

[0057] The diameter of wheel 4211 ranges from 5.8mm to 6.2mm, specifically, the diameter of wheel 4211 is 6.0mm; the width of connecting base 4221 is greater than the width of contact 4222, specifically, the length of connecting base 4221 ranges from 0.8mm to 1.2mm, specifically, the length of connecting base 4221 is 1.0mm; the length of contact 4222 ranges from 2.0mm to 3.0mm, specifically, the length of contact 4222 is 2.5mm.

[0058] Specifically, the fixing points are welding points, and there are two welding points.

[0059] The implementation principle of Example 2 is as follows: the conductive plate 422 is connected to the power supply rail 41 through contact. The conductive plate 422 located at the bottom of the drawer 2 slides on the power supply rail 41 located in the cabinet 1 and always keeps in contact with the power supply rail 41, thereby realizing continuous power supply, improving the service life of the contact 4222, and ensuring that the frequent opening and closing of the drawer 2 and the cabinet 1 will not affect the service life of the contact 4222.

[0060] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
