Referring to fig. 1-6, an embodiment of the present utility model provides a desk lamp 100 capable of preventing a cable 130 from being pulled, including a lamp cap 110, a supporting component 120 and the cable 130; the support assembly 120 comprises a connecting piece 121, a lamp post 122, a bottom plate 123 and a cover plate 124, wherein one end of the connecting piece 121 is hinged with the lamp cap 110, the other end of the connecting piece is connected with the lamp post 122, and the bottom plate 123 and the cover plate 124 are covered and sleeved at the joint of the connecting piece 121 and the lamp post 122; the cover plate 124 is provided with a slot fastening port 1241, one end of the cable 130 is connected to the lamp cap 110, and the other end of the cable is bent through the slot fastening port 1241 to be connected with the lamp post 122. In a specific application, because the connecting piece 121 is hinged to the lamp cap 110, the connecting piece 121 is connected to the lamp post 122, so that the lamp cap 110 can perform pitching motion relative to the lamp post 122, at this time, the lamp cap 110 can pull the cable 130 to move, so as to avoid bad contact caused by damage and loosening of wires due to movement of the cable 130, a groove buckling opening 1241 is formed in the cover plate 124, the groove buckling opening 1241 is used for clamping the cable 130, wherein a part of the cable 130 is clamped in the groove buckling opening 1241 in a bending manner, so that the cable 130 between the cover plate 124 and the lamp post 122 cannot move, and thus, loosening of a wire head at a connection part with the lamp post 122 can be avoided, and in addition, because the cable 130 is bent to pass through the groove buckling opening 1241, movement of the cable 130 at the lamp cap 110 and the cover plate 124 can have a certain extensibility, so that tensile failure of the cable 130 is avoided.

In one possible embodiment, a portion of cable 130 abuts slot 1241 in a semi-arc shape. In particular applications, in order to make the cable 130 have good extensibility, so that the cable 130 can be stretched over the slot fastening opening 1241, a portion of the cable 130 is in a semicircular arc shape and is abutted in the slot fastening opening 1241, so that when the slot fastening opening 1241 and the cable 130 at the lamp cap 110 are extended, the diameter of the semicircular arc-shaped cable 130 is contracted, and when the slot fastening opening 1241 and the cable 130 at the lamp cap 110 are contracted, the diameter of the semicircular arc-shaped cable 130 is expanded, thereby meeting the requirement of extensibility of the cable 130.

In one possible embodiment, when the cover plate 124 is covered on the bottom plate 123, the cable 130 is clamped to the slot 1241. In a specific application, the cover plate 124 is detachably connected with the bottom plate 123, and when the cover plate 124 covers the bottom plate 123, the cable 130 is clamped in the slot fastening 1241, so that the cable 130 can be conveniently mounted.

In particular applications, in order to avoid excessive movement of the cable 130, the adaptor 111 of the light head 110 is disposed adjacent to the connection portion 112, so that the cable 130 can be limited in moving distance when the light head 110 makes pitching movement relative to the light pole 122.

In one possible embodiment, the connector 121 comprises a spherical head 1211 and a cylindrical body 1212, the spherical head 1211 being connected to the cylindrical body 1212, the adapter 111 being formed with a spherical cavity 1111 for mating with the spherical head 1211, the cylindrical body 1212 being connected to the lamp stem 122. In particular applications, in order to diversify the movement modes of the lamp cap 110 and the lamp post 122, such as the rotation of the lamp cap 110 relative to the lamp post 122, the relative movement relationship between the lamp cap 110 and the lamp post 122 is not limited to the pitching movement, so as to provide a wider range of illumination requirements, and therefore, the adapter 111 is formed with a spherical cavity 1111 that mates with the spherical head 1211 to realize a rotational connection.

In one possible embodiment, the cylindrical body 1212 defines a notch surface 12121, the notch surface 12121 being located at an end remote from the spherical head 1211, the notch surface 12121 being adapted to limit rotation of the connector 121 relative to the light stem 122. In particular applications, to avoid rotation of the cylindrical body 1212, the cylindrical body 1212 is formed with a notched surface 12121, and the notched surface 12121 may be machined by a milling cutter at an end remote from the spherical head 1211, thereby limiting rotation of the connector 121 relative to the light stem 122.

In one possible embodiment, one end of the cover plate 124 is provided with a cylindrical hole 1242 for inserting the cylindrical body 1212, a step 1243 is provided in the cylindrical hole 1242, and the step 1243 abuts against the notch surface 12121. In a specific application, the cover plate 124 is provided with a cylindrical hole 1242 for inserting the cylindrical body 1212, and a step 1243 is fixed in the cylindrical hole 1242, so that the step 1243 abuts against the notch surface 12121 to limit the rotation of the cylindrical body 1212, and further limit the rotation of the connecting piece 121 relative to the lamp post 122.

In one possible embodiment, a threaded bore 12122 is provided at an end of the cylindrical body 1212 proximate to the notched surface 12121, and the support assembly 120 further includes a fastener 125, the fastener 125 being coupled to the threaded bore 12122 by abutting the cover plate 124. In a specific application, in order to fix the connecting piece 121 on the cover plate 124, one end of the cylindrical body 1212 near the notch surface 12121 is provided with a threaded hole 12122, the supporting assembly 120 further includes a fastener 125, the fastener 125 abuts against the cover plate 124 and is connected with the threaded hole 12122, and the cover plate 124 is connected with the lamp post 122, so that the lamp post 122 is connected and fixed with the connecting piece 121.

In one possible embodiment, the base 123 is snap-connected to the lamp post 122, and the cable 130 is disposed between the base 123 and the lamp post 122. In a specific application, in order to connect the support assembly 120 with the lamp post 122, the bottom plate 123 is clamped and connected with the lamp post 122, and a portion of the cable 130 is received between the bottom plate 123 and the lamp post 122, so that the desk lamp 100 pulled by the cable 130 can be compact and convenient.
