Description

Technical Field

[0001] The utility model relates to the technical field of table lamps, in particular to a table lamp base fixing mechanism which is convenient for disassembly and assembly. Background Art

[0002] Table lamps are a common lighting tool, usually used for indoor lighting. They are small and lightweight, and can be easily placed on a table or other places. The light source of a table lamp can be a light bulb, LED lamp, or other types of lamps. The design of table lamps varies, ranging from simple modern style to retro classical style. Some table lamps also have a dimming function, which can adjust the brightness as needed. In addition, some table lamps also have USB ports, which can easily charge devices such as mobile phones and tablets.

[0003] Compared with traditional desk lamps, portable desk lamps can be easy to move and install while maintaining the original lighting function. An existing desk lamp base is composed of a C-shaped frame and a screw rod installed on the frame. When in use, the C-shaped frame is stuck on the desktop, and then the screw rod is rotated. As the end of the screw rod gradually approaches and contacts the desktop, the end of the screw rod exerts pressure on the desktop until the frame is fixed on the desktop.

[0004] The above-mentioned table lamp base fixing method requires continuous rotation of the screw rod, especially for a thinner table top, the distance between the end of the screw rod and the bottom of the table top is large, the stroke of the end of the screw rod is far, and the operation is laborious.

[0005] Therefore, it is necessary to provide a table lamp base fixing mechanism that is easy to disassemble and assemble to solve the above technical problems. Utility Model Content

[0006] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a table lamp base fixing mechanism that is easy to disassemble and assemble, which can quickly fix the table lamp base on the desktop, making it convenient to install and disassemble the table lamp.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0008] A table lamp base fixing mechanism that is easy to disassemble and assemble includes: a clamping mechanism, the clamping mechanism includes a first clamping piece, a second clamping piece is provided on the upper end of the first clamping piece, a vertical plate is provided between the first clamping piece and the second clamping piece, a sliding rod is slidably provided on the first clamping piece, a spring is provided on the outer periphery of the sliding rod, a handle is provided at the lower end of the sliding rod, and the spring is in a compressed state.

[0009] Preferably, the surface of the sliding rod is in the shape of equidistant and parallel horizontal threads, the threaded surface of the sliding rod is provided with grooves along the long axis direction, a locking ring is movably mounted on the first clamp, a locking plate is provided on the inner wall of the locking ring, a buckle is fixed on the locking plate, and the buckle can be located in the groove.

[0010] Preferably, the horizontal threads on the surface of the slide rod are composed of annular sheets arranged at equal distances, the grooves are formed by partially breaking the annular sheets, the ends of the annular sheets at the breaking points are inclined, and the lower end of the buckle is arc-shaped.

[0011] Preferably, a clamp is provided at the upper end of the slide rod.

[0012] Preferably, a rubber pad is provided at the lower end of the second clamping piece, and a protrusion is provided on the surface of the rubber pad.

[0013] Preferably, a plastic lamp holder is provided at the upper end of the second clip.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] (1) The utility model achieves the effect of fixing the base of the desk lamp on the desktop by setting a spring and a slide rod. Compared with the existing method of fixing by a screw rod, the device fixes the base by a spring. In terms of operation, the screw rod needs to be rotated continuously to fix it, while the device only needs to be pulled and released after holding to achieve the fixing effect, which is more convenient to operate;

[0016] (2) The utility model realizes the sliding constraint effect of the slide bar on the first clamping piece by setting a locking ring and related components, and the thread on the slide bar is set along the entire length of the outer wall, so that the slide bar can be moved to any position of the slide bar height, thereby adapting to desktops of different thicknesses and achieving the effect of fixing the base on the desktop;

[0017] (3) When the locking ring of the utility model rotates to drive the locking plate and the buckle to rotate, the buckle starts to move from the annular disconnection point of the groove. Processing the end into a triangular inclined surface is conducive to the buckle moving through the inclined surface into the horizontal thread. Similarly, by designing the lower end of the buckle to be an arc shape compared with other planes, it is also convenient for the buckle to move into the horizontal thread.

DETAILED DESCRIPTION

[0026] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0027] First embodiment:

[0028] like Figure 1-5As shown, the table lamp base fixing mechanism provided by the utility model is convenient for disassembly and assembly, including: a clamping mechanism 100, the clamping mechanism 100 includes a first clamping piece 101, a second clamping piece 102 is provided at the upper end of the first clamping piece 101, a vertical plate 103 is provided between the first clamping piece 101 and the second clamping piece 102, this part of the device forms a U shape, and the U-shaped opening part is installed on the desktop, a sliding rod 104 is slidably provided on the first clamping piece 101, a spring 105 is provided on the periphery of the sliding rod 104, a handle 106 is provided at the lower end of the sliding rod 104, a clamping head 111 is provided at the upper end of the sliding rod 104, the clamping head 111 is fixed on the sliding rod 104, and the spring 105 is located between the clamping head 111 and the first clamping piece 101 The spring 105 is in a compressed state. When in use, the slide bar 104 and the clamp 111 are pulled downward by the handle 106. At this time, the spring 105 at the lower end of the clamp 111 is compressed by the pressure of the clamp 111, and the distance between the upper end of the clamp 111 and the second clamp 102 increases. When this distance is greater than the thickness of the desktop, the base is clamped on the desktop, that is, the desktop is clamped between the second clamp 102 and the clamp 111, and then the handle 106 is released. Under the elastic force of the spring 105, the slide bar 104 and the clamp 111 move upward until the clamp 111 contacts the lower end of the desktop and generates a certain pressure. At this time, the base is fixed on the desktop.

[0029] The base of the desk lamp is fixed on the desktop by setting devices such as spring 105 and sliding rod 104. Compared with the existing fixing method by screw rod, this device fixes the base by spring 105. In terms of operation, the screw rod needs to be continuously rotated to fix, while this device only needs to be pulled and released after tightening to achieve the fixing effect, which is more convenient to operate.

[0030] Second embodiment:

[0031] like Figure 2-6 As shown, the surface of the slide bar 104 is in the shape of equidistant and parallel horizontal threads. The threaded surface of the slide bar 104 is provided with grooves 107 along the long axis direction. A locking ring 108 is movably mounted on the first clamp 101. The movably mounted here means that it can be rotated but not moved. The specific implementation structure is as follows Figure 4As shown in the figure, a sliding groove is provided on the outer surface of the sliding rod 104, and a protrusion is provided on the inner wall of the locking ring 108, and the two are adapted to each other. The protrusion on the inner wall of the locking ring 108 can slide in the sliding groove of the sliding rod 104. The overall performance is that the locking ring 108 can rotate axially, while the up and down movement is constrained by the protrusion. A locking plate 109 is fixedly installed on the inner wall of the locking ring 108, and a buckle 110 is fixed on the locking plate 109. The buckle 110 can be located in the groove 107. During the up and down movement of the sliding rod 104, the buckle 110 slides in the groove 107. When the sliding rod 104 moves to a certain position, the locking ring 108 is rotated, and the locking ring 108 drives the locking plate 109 and the buckle 110 to rotate, and the buckle 110 enters between adjacent equidistant and parallel horizontal threads. Since the sliding rod 104 is hindered by the buckle 110, the sliding rod 104 cannot move up and down.

[0032] The locking ring 108 and related components are provided to realize the sliding constraint effect on the slide bar 104 on the first clamp 101, and the thread on the slide bar 104 is provided along the entire length of the outer wall, so that the slide bar 104 can be moved to any position of the height of the slide bar 104, thereby adapting to table tops of different thicknesses and achieving the effect of fixing the base on the table top.

[0033] Third embodiment:

[0034] like Figure 5-6 As shown, the horizontal threads on the surface of the slide rod 104 are composed of annular sheets arranged at equal distances, the groove 107 is formed by partially breaking the annular sheet, the end of the annular sheet at the break is a slope, and the lower end of the buckle 110 is arc-shaped.

[0035] When the locking ring 108 is rotated to drive the locking plate 109 and the buckle 110 to rotate, the buckle 110 starts to move from the annular disconnection of the groove 107. Processing the end into a triangular inclined surface is conducive to the buckle 110 moving into the horizontal thread through the inclined surface. Similarly, by designing the lower end of the buckle 110 to be an arc compared with other planes, it is also convenient for the buckle 110 to move into the horizontal thread.

[0036] Fourth embodiment:

[0037] like Figure 2 As shown, a rubber pad 112 is provided at the lower end of the second clamp 102, and a protrusion is provided on the surface of the rubber pad 112. When in use, the rubber pad 112 contacts the upper surface of the desktop, and a large pressure is generated when clamping. The rubber pad 112 is softer than the second clamp 102 made of plastic or metal materials and can protect the desktop.

[0038] Fifth embodiment:

[0039] like Figure 1 , Figure 7As shown, a plastic lamp holder 200 is provided at the upper end of the second clip 102 . The plastic lamp holder 200 refers to a plastic metal strip in the prior art, which can be bent into a variety of shapes and has a certain supporting capacity. The lamp bead lighting part of the desk lamp is installed at the end of the plastic lamp holder 200 .

[0040] When in use, first pull the handle 106 downward to drive the slide bar 104 and the clamp 111 to move downward, the distance between the clamp 111 and the second clamp 102 increases, the base clamping part "opens", and then is placed on the desktop part, and then the handle 106 is released, and under the elastic force of the spring 105, the slide bar 104 and the clamp 111 move upward to clamp the desktop, and finally the locking ring 108 is rotated to fix the position of the slide bar 104 to complete the fixation.

[0041] The above embodiment is only one of the preferred implementation modes of the present utility model and should not be used to limit the protection scope of the present utility model. Any changes or modifications that are made to the main design concept and spirit of the present utility model without any substantive significance, as long as the technical problems solved are still consistent with the present utility model, should be included in the protection scope of the present utility model.
