An LED lamp holder

Abstract

The application discloses an LED lamp holder and belongs to the technical field of lamp holders. Mainly comprising: a base, a supporting column fixedly installed on the upper end of the base, a fastening assembly movably and limitingly installed on the middle part of the upper end of the supporting column, a lamp holder fixedly installed on the upper end of the fastening assembly, and a shaft fixing assembly fixedly installed on the middle part of the upper end of the two sides of the supporting column. After a period of friction adjustment, the stability of the lamp holder is poor after the angle adjustment. First, the knob is rotated to drive the threaded column to rotate. Under the threaded connection of the threaded column and the second threaded hole, the threaded column is inserted into the middle part of the inner cavity of the second threaded hole and the second insertion hole, so that one end of the threaded column abuts against the lower end outer surface of the inner column body, thereby compensating for the problem that the friction force of the internal connecting mechanism and the external connecting mechanism becomes small after a long time of friction rotation, and the lamp holder is kept stable after the angle adjustment.

Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to an LED lamp holder. Background Technology

[0002] LED light stands are primarily used to fix and support LED lighting fixtures. Their basic structure includes a main frame and fixing devices, and they are commonly made of plastic, aluminum alloy, or steel. These light stands are suitable for indoor dry areas, humid areas, and outdoor scenarios, and are widely used in home, commercial, industrial, and outdoor lighting applications.

[0003] Currently, the LED lamp holders used in homes are mainly folding table lamps. Folding table lamps adjust their angle by using the friction of their internal structure. This method leads to wear and tear on the internal structure of the LED lamp holder after a period of use, resulting in insufficient friction and the internal structure being unable to support the adjusted angle of the lamp holder.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0005] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide an LED lamp holder that solves the problem that after a period of use, the internal structure of the LED lamp holder is worn, the friction is insufficient, and the internal structure cannot support the angle after the lamp holder is adjusted.

[0006] The technical solution adopted by this application to solve its technical problem is: an LED lamp holder, including a base and a support column fixedly installed on the middle of one side of the upper end of the base, a fastening component is movablely limited and installed in the middle of the upper end of the support column, a lamp head is fixedly installed on the outer surface of the upper end of the fastening component, and a threaded shaft fixing component is respectively fixed in the middle of the upper two sides of the outer wall of the support column.

[0007] The fastening assembly includes an internal connecting mechanism and an external connecting mechanism coaxially nested on the outer surface of the internal connecting mechanism, with a screw-fixed screw mechanism at the lower middle of the external connecting mechanism.

[0008] Furthermore, the support column includes a column and connecting holes respectively opened in the middle of the upper part of the outer wall on both sides of the column, and the two ends of the groove of the connecting hole are respectively opened with first threaded holes.

[0009] Furthermore, the internal connection mechanism includes an inner column and first insertion holes respectively opened at the middle of both ends of the outer wall of the inner column.

[0010] Furthermore, the external connection mechanism includes an outer column and a second insertion hole opened in the middle of the lower end of the outer column, a connecting block fixedly installed in the middle of the upper end of the outer column, a fixing short block fixedly installed in the middle of the outer surface of the lower end of the outer column, and a second threaded hole opened in the middle of the lower end of the fixing short block.

[0011] Furthermore, the screwing mechanism includes a knob and a threaded post fixedly installed at the middle of the upper end of the knob.

[0012] Furthermore, the shaft fixing assembly includes a fixed long block and fixing screw holes opened in the middle of both sides of the fixed long block. The middle of the inner cavity of the fixing screw hole is connected to a screw by a thread, and a stop block is fixedly connected to the middle of one side of the fixed long block.

[0013] The beneficial effects of this application are as follows: The LED lamp holder provided by this application uses an internal connecting mechanism, an external connecting mechanism, a lamp holder, a knob, a threaded column, a second threaded hole, and a second insertion hole in cooperation, so that one end of the threaded column abuts against the lower outer surface of the inner column, thereby compensating for the problem that the friction between the internal connecting mechanism and the external connecting mechanism decreases after long-term frictional rotation. This setting makes the lamp head remain stable after the angle is adjusted.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0024] like Figure 1 As shown, an LED lamp holder includes a base 1 and a support column 2 fixedly installed on the middle of one side of the upper end of the base 1. A locking component 4 is movablely limited and installed in the middle of the upper end of the support column 2. A lamp head 3 is fixedly installed on the outer surface of the upper end of the locking component 4. The locking component 4 is set for adjusting and fixing the angle of the lamp head 3. The upper sides of the outer wall of the support column 2 are respectively threaded to fix shaft fixing components 5.

[0025] like Figure 2 As shown, the locking assembly 4 includes an internal connecting mechanism 41 and an external connecting mechanism 42 coaxially nested on the outer surface of the internal connecting mechanism 41. The lower middle part of the external connecting mechanism 42 is threaded to fix a screwing mechanism 43. The internal connecting mechanism 41 is configured to provide a friction object for the external connecting mechanism 42 and support the locking assembly 4. The external connecting mechanism 42 is configured to generate friction with the internal connecting mechanism 41 to adjust and fix the lamp head 3 at an angle. The screwing mechanism 43 is configured to increase or decrease the friction between the internal connecting mechanism 41 and the external connecting mechanism 42.

[0026] like Figure 2 As shown, the support column 2 includes a column 21 and connecting holes 22 respectively opened in the middle of the upper part of the outer wall on both sides of the column 21. The two ends of the groove of the connecting hole 22 are respectively opened with first threaded holes 23. The connecting hole 22 is set to play a role in limiting the movement of the internal connecting mechanism 41.

[0027] like Figure 3 As shown, the internal connection mechanism 41 includes an inner column 411 and first insertion holes 412 respectively opened at the middle of both ends of the outer wall of the inner column 411. The two ends of the inner column 411 pass through the middle of the connection hole 22 respectively.

[0028] like Figure 3 As shown, the external connection mechanism 42 includes an outer column 421 and a second insertion hole 422 opened in the middle of the lower end of the outer column 421. A connecting block 423 is fixedly installed in the middle of the upper end of the outer column 421, and a fixing short block 424 is fixedly installed in the middle of the outer surface of the lower end of the outer column 421. A second threaded hole 425 is opened in the middle of the lower end of the fixing short block 424. The outer column 421 generates friction with the inner column 411 through rotation, which plays a role in adjusting the angle and stabilizing the connecting block 423. The connecting block 423 is used to fix the lamp head 3 and the outer column 421.

[0029] The two ends of the external connection mechanism 42 are movable limiters installed at the middle of the upper end of the inner wall of the support column 2.

[0030] like Figure 3 As shown, the screwing mechanism 43 includes a knob 431 and a threaded post 432 fixedly installed in the middle of the upper end of the knob 431. The knob 431 is designed so that rotation under external conditions first drives the threaded post 432 to rotate. Then, the threaded post 432 and the threaded hole 425 cooperate with each other. The threaded post 432 passes through the middle of the inner cavity of the second threaded hole 425 and the second insertion hole 422, and abuts against the lower outer surface of the inner post 411, so that the contact area between the outer surface of the inner post 411 and the inner surface of the outer post 421 increases, thereby increasing the friction and fixing the adjustment angle.

[0031] In this application, the sliding friction between the internal connecting mechanism 41 and the external connecting mechanism 42, with the external connecting mechanism 42 fixedly connected to the lamp holder 3, serves to adjust and stabilize the angle of the lamp holder 3. After a period of frictional adjustment using the internal connecting mechanism 41 and the external connecting mechanism 42, wear occurs at the connection point, resulting in poor stability of the lamp holder 3 after angle adjustment. At this point, by first rotating the knob 431, the threaded post 432 is rotated, and the threaded connection between the threaded post 432 and the second threaded hole 425 is established. Under the action, the threaded post 432 penetrates into the middle of the inner cavity of the second threaded hole 425 and the second insertion hole 422, so that one end of the threaded post 432 abuts against the lower outer surface of the inner post 411, thereby compensating for the problem that the friction between the inner connecting mechanism 41 and the outer connecting mechanism 42 decreases after long-term frictional rotation. By setting the threaded post 432, the contact area between the outer surface of the inner post 411 and the inner surface of the outer post 421 is increased, which increases the friction. This setting makes the lamp head 3 remain stable after the angle is adjusted.

[0032] like Figure 3 and Figure 4 As shown, the shaft fixing assembly 5 includes a fixing block 51 and fixing screw holes 52 opened in the middle of both sides of the fixing block 51. The middle of the inner cavity of the fixing screw hole 52 is connected to a screw 53 by thread. The middle of one side of the fixing block 51 is fixedly connected to a stop block 54. The screw 53 is set so that the screw 53 can be rotated by the thread structure of the fixing screw hole 52 and the screw 53. The screw 53 passes through the middle of the inner cavity of the fixing screw hole 52 and the first threaded hole 23 for fixing, which plays the role of thread fixing the fixing block 51. The stop block 54 can play the role of fixing the first insertion hole 412 by inserting into the first insertion hole 412.

[0033] In this application, when the LED lamp holder needs to replace or repair parts, the screw 53 is first rotated in the reverse direction using a screwdriver or other tools. After the screw 53 is removed from the middle of the inner cavity of the first threaded hole 23 and the fixing screw hole 52, the fixing block 51 is removed, and the stop block 54 is also removed from the middle of the inner cavity of the first insertion hole 412. At this time, the internal connecting mechanism 41 is installed in the middle of the inner cavity of the connecting hole 22. Since the lamp head 3 and the fastening assembly 4 are installed in the middle of the upper inner wall of the support column 2 through the internal connecting mechanism 41, after the internal connecting mechanism 41 is removed from the middle of the inner cavity of the connecting hole 22, the lamp head 3 and the fastening assembly 4 can move freely. This setting can easily realize the replacement or repair of the internal connecting mechanism 41 or other internal parts.

[0034] In summary: By using the knob 431, threaded post 432, second threaded hole 425, second insertion hole 422, inner post 411, and outer post 421 in combination, one end of the threaded post 432 abuts against the lower outer surface of the inner post 411, thereby compensating for the problem of reduced friction between the internal connecting mechanism 41 and the external connecting mechanism 42 after long-term frictional rotation. The threaded post 432 increases the contact area between the outer surface of the inner post 411 and the inner surface of the outer post 421, thereby increasing the friction. This design ensures that the lamp head 3 remains stable after the angle is adjusted. By using the screw 53, first threaded hole 23, fixing screw hole 52, fixing long block 51, stop block 54, first insertion hole 412, internal connecting mechanism 41, connecting hole 22, lamp head 3, fastening component 4, and support post 2 in combination, this design allows for easy replacement or repair of the internal connecting mechanism 41 or other parts.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
