Description

Technical Field

[0001] The present invention relates to the technical field of lamp equipment, and in particular to a ceiling lamp and a use method thereof. Background Art

[0002] Ceiling lamps are a type of lamps. As the name suggests, they are called ceiling lamps because the top of the lamp is relatively flat and the bottom is completely attached to the roof when installed. In modern life, living space is limited, so ceiling lamps have gradually replaced chandeliers and become a fashionable choice for modern home decoration due to their space-saving, simple and textured features. However, there are also some problems with existing ceiling lamps during use, such as:

[0003] First, when ordinary lamp users install and use the lamp, they use several buckles arranged around the lamp frame to fix the lamp frame and the tray (set-top box). At this time, they need to manually turn several buckles to fasten the tray (set-top box). Not only does it require many operations, but it also requires at least two people to work together to install. If the buckles are not strong enough, it may also lead to problems such as loose fixation and large installation gap, which makes the ceiling lamp easy to shake.

[0004] Second, when ordinary lamps are installed and wired, the plug connector in the lamp frame assembly and the plug connector in the tray (set-top box) are connected by connecting male and female plugs. Therefore, each installation and disassembly requires manual plugging and unplugging, which makes disassembly and assembly inconvenient. If the power is forgotten to turn off during disassembly and assembly, electric shock may occur, endangering the life of the operator. If the power is turned off for disassembly and assembly, it will affect other electricity needs in the home.

[0005] In order to solve the above problems, many relevant technical solutions are disclosed in the prior art. After searching, a patent named replaceable quick-installation ceiling lamp is obtained, with application number 2017103751947 and publication date September 15, 2017. The patent comprises a mounting frame, a base, a light source assembly, a lampshade and a plurality of locking pieces. Both ends of the mounting frame are mounted on the base through locking pieces. The outer portion of the locking piece protrudes from the outer wall of the base. The inner wall of the lampshade is provided with a plurality of buckle parts. The locking piece protruding from the outer side of the base is snapped into the buckle parts. The base and the lampshade are mutually enclosed to form an accommodating space. The light source assembly is installed in the accommodating space. By providing the locking piece and the buckle part, the disassembly and assembly between the base and the lampshade are easier, and it is convenient to replace ceiling lamps of different sizes. The locking piece can lock the mounting frame on the base, and can also detachably connect the base and the lampshade. However, this solution still has the following shortcomings: in order to prevent the locking piece from disengaging from the buckle part in the reverse direction, an upward groove is provided on the buckle part. In actual use, if the depth of the groove is too small, it is difficult to achieve the desired locking and anti-reverse disengagement effect. If the depth of the groove is too large, it will inevitably cause the mounting frame to be translated in the reverse direction relative to the lampshade for a distance after being screwed into the buckle part. Due to the existence of this gap, the ceiling lamp is prone to shaking and cannot be securely locked.

[0006] In order to better solve the problem of fast and safe disassembly and assembly of ceiling lamps, people are in urgent need of a more reliable ceiling lamp. Summary of the invention

[0018] Preferably, elastic pulling wires are connected between the columns.

[0019] A method for using a ceiling lamp, comprising the following steps:

[0020] S1. Tray installation: Use fixing bolts to fix the tray on the building, pass the power supply wires reserved on the building through the through holes reserved on the tray, and insert them into the corresponding holes where the wiring springs are located;

[0021] S2. Install the lamp frame: the upper end surface of the sliding buckle on the lamp frame is an inclined surface, and the lower end surface is a horizontal surface. The sliding buckle is pressed against the position of the annular groove of the tray. When the lamp frame is pushed upward, an extrusion force is generated on the inclined surface. The radial component of the extrusion force compresses the first spring on the corresponding side, so that the sliding buckle is retracted into the lamp frame. When the sliding buckle moves up to the annular groove, the sliding buckle is ejected by the first spring and is clamped in the annular groove with its horizontal lower end surface, thereby fixing the lamp frame on the tray.

[0022] S3. Conductivity: When installing the lamp frame, the contacts on the lamp frame are inserted into the lamp connector and pressed against the conductive sheet to conduct current into the lamp frame; the conductive sheet includes an L-pole contact sheet and an N-pole contact sheet, and the N-pole contact sheet is a semicircular ring structure arranged on the periphery of the L-pole contact sheet; there are three contacts in total, arranged in a line, and a second spring is provided inside the contacts, and the second spring presses the contact tightly against the corresponding conductive sheet, and the middle contact is always in contact with the L-pole contact sheet; when rotating the lamp frame, the contacts on both sides can switch to contact with the N-pole contact sheet to ensure that at least one of the contacts is in contact with the N-pole contact sheet.

[0026] Preferably, the elastic pulling wire is arranged in the middle of the positioning claw to provide a larger torque to the positioning claw without interfering with the fit between the inwardly extending end and the slide-out slot and the slide-in slot.

[0027] 3. Beneficial effects

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] (1) The present invention adopts a modular assembly structure to integrate and optimize the assembly and coupling methods between the tray and the lamp frame, and between the power supply line and the lamp circuit, and integrates and fixes the plug-in circuit in the lamp connector. During coupling, the lamp can be connected by a connection method similar to that between a plug and a socket, thereby realizing quick wiring operation for lamp installation; a retractable sliding buckle is used to realize quick engagement with the annular groove, and a guide foot and an exit are provided. The sliding buckle is compressed by the guide foot so that the sliding buckle can slide to the exit, thereby realizing more convenient and efficient assembly and disassembly operations of the lamp frame.

[0030] (2) In order not to affect the rotation of the lamp frame relative to the tray, the present invention provides a fixed L-pole contact piece and a semicircular ring-shaped N-pole contact piece located on the periphery of the L-pole contact piece. There are three contacts in total, which are arranged in a line, and the middle contact is always in contact with the L-pole contact piece. When the lamp frame is rotated, the contacts on both sides can switch to contact with the N-pole contact piece, ensuring that at least one of the contacts is in contact with the N-pole contact piece, avoiding a gap during rotation, and ensuring connection when installed at any angle.

[0031] (3) The present invention flexibly installs the lamp connector on the tray through the third spring, and then adopts the method of cooperating the positioning claw with the slide-out slot and the slide-in slot to realize that the positioning claw pushes the lamp connector to retract, thereby realizing electrical isolation between the lamp frame and the tray, ensuring that the operator will not be electrocuted when the lamp has a short circuit or other fault.

[0032] (4) The present invention sets the groove depth of the slide-out groove and the slide-in slot to be smaller than the step surface width of the step structure. After the inwardly extending end slides out through the slide-out groove to the step surface, the inner side surface of the inwardly extending end is pressed against the outer side surface of the lamp connector. The size difference between the step surface and the slide-out groove and the slide-in slot is used as a blocking structure to prevent the inwardly extending end from sliding into the slide-out groove or the slide-in slot again, so that the operator can smoothly rotate the lamp frame to remove the lamp frame.

DETAILED DESCRIPTION

[0048] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below.

[0049] Example 1

[0050] like Figures 1 to 10 As shown, a ceiling lamp comprises a lamp frame 2 and a tray 1 mounted with the lamp frame 2, and the lamp frame 2 and the tray 1 are connected through the conductive sheet 3 and the contact 4 respectively mounted on the two. Specifically, a lamp connector 7 with integrated wires is mounted on the tray 1, and a wiring spring 701 connected to the power line and a conductive sheet 3 connected to the wiring spring 701 are provided on the lamp connector 7. The wiring spring 701 uses elastic force to press the power line inserted therebetween, so as to facilitate the quick connection of the line. The conductive sheet 3 comprises a wiring terminal and a coupling end connected to the wiring spring 701, and the coupling end is further divided into an L-pole contact sheet 301 connected to the live line and an N-pole contact sheet 302 connected to the neutral line. When the contact mounted on the lamp frame 2 contacts the corresponding L-pole contact sheet 301 and N-pole contact sheet 302, the current in the power line is sequentially transmitted to the contact 4 through the wiring spring 701, the conductive sheet 3, the L-pole contact sheet 301 and the N-pole contact sheet 302, so that the lamp source in the lamp frame 2 is electrically lit.

[0051] Furthermore, in order to enable the contact 4 to be reliably pressed against the corresponding L-pole contact piece 301 and the N-pole contact piece 302 to prevent poor contact or even breakdown and short circuit at the moment of power-on, the present invention has a second spring built into the contact 4. The second spring provides a holding force for the pressing of the contact 4, ensuring good contact and avoiding damage to the L-pole contact piece 301 and the N-pole contact piece 302.

[0052] Two sliding buckles 5 are installed inside the lamp frame 2 of the present invention. The two sliding buckles 5 are symmetrical about the central axis of the lamp frame 2. A first spring 6 is provided between the inner end of the sliding buckle 5 and the lamp frame 2. The two ends of the first spring 6 are respectively in contact with the lamp frame 2 and the sliding buckle 5 on the corresponding side. The movement path of the sliding buckle 5 is limited by the sliding track formed on the lamp frame 2. When in use, the first spring 6 can push the sliding buckle 5 out of the lamp frame 2; an annular groove 101 is provided on the inner side wall of the tray 1 of the present invention, and at least two exit openings 102 corresponding to the positions of the sliding buckles 5 are provided on the annular groove 101. A guide foot 103 protruding inwardly is provided on both sides of each exit opening 102, and the guide foot 103 is away from the exit opening 10 A guiding inclined surface which is smoothly connected with the annular groove 101 is formed on one side of 2, and the size of the annular groove 101 is matched with the size of the sliding buckle 5. When in use, the lamp frame 2 is pushed upward, and the inclined surface set on the sliding buckle 5 is squeezed and contracted by the tray 1. When the sliding buckle 5 of the lamp frame 2 moves up into the annular groove 101, the first spring 6 pops out the sliding buckle 5, and the lamp frame 2 is fixed on the tray 1 by utilizing the engagement between the sliding buckle 5 and the annular groove 101; when the lamp frame 2 needs to be rotated and removed, the sliding buckle 5 is slid to the guide foot 103 and continues to rotate. The guiding inclined surface compresses the sliding buckle 5 inward until the sliding buckle 5 slides over the guide foot 103 to the exit 102, and the lamp frame 2 is detached from the tray 1.

[0053] A method for using a ceiling lamp, comprising the following steps:

[0054] S1. Tray installation: Fix the tray 1 on the building with fixing bolts, pass the power supply wires reserved on the building through the through holes reserved on the tray 1, and insert them into the corresponding holes where the wiring spring pieces 701 are located;

[0055] S2. Install the lamp frame: the upper end surface of the sliding buckle 5 on the lamp frame 2 is an inclined surface, and the lower end surface is a horizontal surface. The sliding buckle 5 is pressed against the position of the annular groove 101 of the tray 1. When the lamp frame 2 is pushed upward, an extrusion force is generated on the inclined surface. The radial component of the extrusion force compresses the first spring 6 on the corresponding side, so that the sliding buckle 5 is retracted into the interior of the lamp frame 2. When the sliding buckle 5 moves up to the annular groove 101, the sliding buckle 5 is ejected by the first spring 6, and its horizontal lower end surface is stuck in the annular groove 101, so that the lamp frame 2 is fixed on the tray 1;

[0056] S3, conduction: when installing the lamp frame 2, the contact 4 on the lamp frame 2 is inserted into the lamp connector 7 and pressed against the conductive sheet 3 to conduct current into the lamp frame 2; the conductive sheet 3 includes an L-pole contact sheet 301 and an N-pole contact sheet 302, and the N-pole contact sheet 302 is a semicircular ring structure arranged on the periphery of the L-pole contact sheet 301; there are three contacts 4 arranged in a line, and a second spring is provided inside the contact 4, and the second spring presses the contact 4 tightly against the corresponding conductive sheet 3, and the middle contact 4 is always in contact with the L-pole contact sheet 301; when rotating the lamp frame 2, the contacts 4 on both sides can switch to contact with the N-pole contact sheet 302, ensuring that at least one of the contacts 4 is in contact with the N-pole contact sheet 302;

[0057] S4. Disassemble the lamp frame: rotate the lamp frame 2. When the sliding buckle 5 rotates to the guide foot 103 of the tray 1, the guide foot 103 pushes the sliding buckle 5 to retract into the interior of the lamp frame 2. When the sliding buckle 5 continues to rotate to the exit 102 of the tray 1, the lamp frame 2 is completely detached from the tray 1.

[0058] Example 2

[0059] like Figures 1 to 14As shown, on the basis of keeping the basic technical scheme of Example 1 unchanged, a third spring 9 is provided between the lamp connector 7 and the tray 1 of the present disclosure, the purpose of which is to achieve flexible positioning of the lamp connector 7 relative to the tray 1, a circle of step structures 702 is provided on the lower end surface of the lamp connector 7, and a plurality of sliding slots 703 are provided on the outer peripheral side surface of the step structure 702, the sliding slots 703 are arranged along the axial direction of the connector, and the lower end of the sliding slot 703 extends to the step surface of the step structure 702; the step structure 702 The outer peripheral side surface is also provided with slide-out grooves 704, which are equal in number to the slide slots 703 and are arranged one-to-one with the slide slots 703. The slide-out grooves 704 are all arched structures. The middle part of the slide-out groove 704 is connected to the upper end of the slide slot 703, and both ends of the slide-out groove 704 extend to the step surface of the step structure 702; the step surface width of the step structure 702 is greater than the groove depth of the slide-out groove 704 and the slide slot 703, so that a certain margin is left on the step surface of the slide-out groove 704 and the slide slot 703. The lamp frame 2 of the present disclosure is provided with two positioning claws 10, each of which includes a column 10a mounted on the lamp frame 2 and an inwardly extending end 10b arranged on the inner side of the column 10a, and the extending length of the inwardly extending end 10b is greater than the slide-out groove 704 or the groove depth of the slide-out groove 704, so as to ensure that the inwardly extending end 10b can be fully buckled in the slide-out groove 704 or the slide-out groove 704. When in use, the inwardly extending end 10b slides along the slide slot 703 to the uppermost end of the slide slot 703, that is, reaches the slide-out groove 704, and at this time the sliding buckle 5 is just buckled in the annular groove 101; it is required When the lamp frame 2 is rotated to be taken off, as the lamp frame 2 rotates, the inwardly extending end 10b slides along the arched slide-out groove 704, and the slide-out groove 704 gradually pushes the inwardly extending end 10b to the step surface of the step structure 702 with its inclined trajectory. Since the axial relative position of the lamp frame 2 and the tray 1 has not changed at this time, the inwardly extending end 10b does not actually move downward at this time, but pushes the lamp connector 7 upward, and the lamp connector 7 is pre-decoupled from the contact 4 by squeezing the third spring 9, thereby achieving early power off and ensuring the safety of electricity when the operator touches the lamp frame 2.

[0060] Furthermore, in order to ensure that the inwardly protruding end 10b is smoothly inserted into the sliding slot 703, the present invention connects an elastic pull wire 11 between the columns 10a and sets the column 10a in an area further outward than the actual mating position. At this time, the inwardly protruding end 10b will not protrude inward excessively to avoid being hindered by the step surface, thereby smoothly sliding into the sliding slot 703 on the corresponding side. As the lamp connector 7 is pressed downward, the elastic pull wire 11 is compressed and the column 10a is pulled inward and bent, so that the inwardly protruding end 10b is fully fitted with the sliding slot 703. When the lamp frame 2 is rotated, even if the inwardly protruding end 10b has slid to the step surface, since there is still a part on the step surface that has not been cut off by the sliding slot 704 and the sliding slot 703, this part can ensure that the inwardly protruding end 10b slides on the step surface without sliding into the sliding slot 704 or the sliding slot 703 again, thereby maintaining the pressure on the lamp connector 7 and keeping the lamp frame 2 in the power-off state.

[0061] Furthermore, in order to prevent the elastic pulling wire 11 from interfering with the contact 4 , the middle portion of the elastic pulling wire 11 is configured as an annular rigid structure so as to avoid the contact 4 .

[0062] A method for using a ceiling lamp, comprising the following steps:

[0063] S1. Installing the tray 1: Fix the tray 1 on the building with fixing bolts, pass the power supply wires reserved on the building through the through holes reserved on the tray 1, and insert them into the corresponding holes where the wiring spring pieces 701 are located;

[0064] S2, installing the lamp frame 2: the upper end surface of the sliding buckle 5 on the lamp frame 2 is an inclined surface, and the lower end surface is a horizontal surface. The sliding buckle 5 is pressed against the position of the annular groove 101 of the tray 1. When the lamp frame 2 is pushed upward, an extrusion force is generated on the inclined surface. The radial component of the extrusion force compresses the first spring 6 on the corresponding side, so that the sliding buckle 5 is retracted into the interior of the lamp frame 2. When the sliding buckle 5 moves up to the annular groove 101, the sliding buckle 5 is ejected by the first spring 6, and its horizontal lower end surface is stuck in the annular groove 101, so that the lamp frame 2 is fixed on the tray 1;

[0065] S3, conduction: when installing the lamp frame 2, the contact 4 on the lamp frame 2 is inserted into the lamp connector 7 and pressed against the conductive sheet 3 to conduct current into the lamp frame 2; the conductive sheet 3 includes an L-pole contact sheet 301 and an N-pole contact sheet 302, and the N-pole contact sheet 302 is a semicircular ring structure arranged on the periphery of the L-pole contact sheet 301; there are three contacts 4 arranged in a line, and a second spring is provided inside the contact 4, and the second spring presses the contact 4 tightly against the corresponding conductive sheet 3, and the middle contact 4 is always in contact with the L-pole contact sheet 301; when rotating the lamp frame 2, the contacts 4 on both sides can switch to contact with the N-pole contact sheet 302, ensuring that at least one of the contacts 4 is in contact with the N-pole contact sheet 302.

[0066] S4, accessory locking: when installing the lamp frame 2, the inwardly extending end 10b of the column 10a moves up along the corresponding sliding slot 703, and at the same time, the lamp frame 2 is pressed on the elastic pull wire 11 between the columns 10a, and the elastic pull wire 11 is gradually tightened to pull the column 10a inward, and the inwardly extending end 10b is completely buckled in the sliding slot 703;

[0067] S5, power off: when the lamp frame 2 is rotated out, the inwardly extending end 10b slides out along the slide-out groove 704 to the step structure 702. At the same time, the lamp connector 7 is pushed by the positioning claw 10 to compress the third spring 9 and shrink upward, so that the lamp connector 7 is decoupled from the contact 4.

[0068] S6. Disassemble the lamp frame 2: Rotate the lamp frame 2. When the sliding buckle 5 rotates to the guide foot 103 of the tray 1, the guide foot 103 pushes the sliding buckle 5 to retract into the interior of the lamp frame 2. When the sliding buckle 5 continues to rotate to the exit 102 of the tray 1, the lamp frame 2 is completely detached from the tray 1.

[0069] The elastic pulling wire 11 is arranged in the middle of the positioning claw 10 .
