Description

Technical Field

[0001] This utility model relates to the technical field of posture correction devices, specifically to a gantry lamp. Background Technology

[0002] A study desk is a commonly used writing platform, and the lighting conditions of the study environment are an important factor affecting eyesight and posture. Insufficient light or uneven light distribution can cause users to unconsciously move closer to the desk, thus exacerbating poor posture. Therefore, in recent years, some study desks with lighting functions have appeared on the market.

[0003] The lighting fixtures on these study desks are usually fixed in position relative to the desktop. However, since the users of these study desks are mostly teenagers and children, whose heights vary greatly, they have different requirements for the lighting angle of the fixtures. Therefore, how to adapt to the different lighting angle requirements of teenagers and children of different heights has become a focus of consumer attention.

[0004] Therefore, developing a gantry lamp with a simple structure, convenient operation, and adjustable lighting angle is of great practical significance. Utility Model Content

[0005] This utility model proposes a gantry table lamp. By setting a first rotating shaft and a second rotating shaft at the beginning and end of the movable swing arm, the lamp head mechanism can form different relative positions with the movable swing arm and the connecting parts. Under the action of the first damping mechanism and the second damping mechanism, the relative position between the lamp head mechanism and the movable swing arm and the connecting parts can be fixed and positioned, and it is not easy to cause accidental displacement during use. This satisfies the different needs of users of different heights for the relative position of the lamp head mechanism and improves the adaptability of the product.

[0006] A gantry lamp designed for this purpose includes a lamp head mechanism, a movable swing arm, and a connector for connecting and cooperating with a lamp support. The two ends of the movable swing arm are connected and cooperate with the connector and the lamp head mechanism, respectively. A first rotating shaft and a first damping mechanism are provided between the connector and the movable swing arm. The movable swing arm can rotate relative to the connector around the first rotating shaft. The relative position between the movable swing arm and the connector is limited and fixed by the first damping mechanism. A second rotating shaft and a second damping mechanism are provided between the lamp head mechanism and the movable swing arm. The lamp head mechanism can rotate relative to the movable swing arm around the second rotating shaft. The relative position between the lamp head mechanism and the movable swing arm is limited and fixed by the second damping mechanism.

[0007] The first damping mechanism includes a first locking member, a limiting cavity, and a connecting part. The limiting cavity and the connecting part are respectively disposed on the connecting member and the movable rocker arm. The first locking member can tighten or loosen the limiting cavity to increase or decrease the static friction between the limiting cavity and the connecting part.

[0008] The first locking component includes a first locking screw, a first rotating shaft located at the central axis of the first locking screw, the first locking screw passing through the limiting cavity and the connecting part respectively, the first locking screw and the side wall of the limiting cavity are connected and engaged by a threaded structure, the limiting cavity can elastically deform, and the first locking screw tightens the limiting cavity by rotating forward or loosens the limiting cavity by rotating in reverse.

[0009] The second damping mechanism includes a second locking member and a connecting edge and a limiting groove that slide against each other. The limiting groove and the connecting edge are respectively disposed on the movable rocker arm and the lamp head mechanism. The second locking member can make the lamp head mechanism and the movable rocker arm move closer or further apart. When the lamp head mechanism and the movable rocker arm move closer together, the contact area and static friction between the connecting edge and the limiting groove increase. Alternatively, when the lamp head mechanism and the movable rocker arm move further apart, the contact area and static friction between the connecting edge and the limiting groove decrease.

[0010] The second locking component includes a second locking screw, a second rotating shaft located at the center of the second locking screw, the second locking screw passing through the tail end of the movable rocker arm and connected to the lamp head mechanism via a threaded structure, and the second locking screw causing the lamp head mechanism to move closer to or further away from the movable rocker arm by rotating forward or backward.

[0011] The lamp head mechanism is connected to corresponding movable swing arms on its left and right sides, and the two movable swing arms are connected to the lamp head mechanism to form a frame structure with left and right symmetry.

[0012] The inner side of the connector is hollow, and several ribs are distributed on the inner side of the connector, which are staggered with each other.

[0013] The lamp holder mechanism includes a lamp housing and a lighting mechanism and an electrical control mechanism disposed within the lamp housing, with the lighting mechanism and the electrical control mechanism being electrically connected.

[0014] The beneficial technical effects of this utility model are as follows:

[0015] By setting a first pivot and a second pivot at the beginning and end of the movable swing arm respectively, the lamp head mechanism can form different relative positions with the movable swing arm and the connecting parts. Under the action of the first damping mechanism and the second damping mechanism, the relative position between the lamp head mechanism and the movable swing arm and the connecting parts can be fixed and positioned, and it is not easy for accidental displacement to occur during use. This satisfies the different needs of users of different heights for the relative position of the lamp head mechanism and improves the adaptability of the product. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0026] See Figures 1-8 A gantry lamp includes a lamp head mechanism 1, a movable swing arm 2, and a connector 3 for connecting and cooperating with a lamp support 5. The two ends of the movable swing arm 2 are respectively connected and cooperating with the connector 3 and the lamp head mechanism 1. A first rotating shaft and a first damping mechanism are provided between the connector 3 and the movable swing arm 2. The movable swing arm 2 can rotate relative to the connector 3 around the first rotating shaft. The relative position between the movable swing arm 2 and the connector 3 is limited and fixed by the first damping mechanism. A second rotating shaft and a second damping mechanism are provided between the lamp head mechanism 1 and the movable swing arm 2. The lamp head mechanism 1 can rotate relative to the movable swing arm 2 around the second rotating shaft. The relative position between the lamp head mechanism 1 and the movable swing arm 2 is limited and fixed by the second damping mechanism.

[0027] A desk lamp support refers to a component that can be used to support a cage-door desk lamp, such as the tabletop of a desk or the outer frame of a monitor. These desk lamp supports only need to have a connecting structure on their surface that can mate with connector 3.

[0028] By setting a first rotating shaft and a second rotating shaft at the beginning and end of the movable swing arm 2 respectively, the lamp head mechanism 1 can form different relative positions with the movable swing arm 2 and the connecting piece 3. Under the action of the first damping mechanism and the second damping mechanism, the relative position between the lamp head mechanism 1 and the movable swing arm 2 and the connecting piece 3 can be fixed and positioned, and it is not easy for accidental displacement to occur during use. This satisfies the different needs of users of different heights for the relative position of the lamp head mechanism 1 and improves the adaptability of the product.

[0029] During use, the movable swing arm 2 can drive the lamp head mechanism 1 to rotate around the first rotating axis, thereby forming different relative positions with the connecting piece 3 and adjusting the relative height between the lamp head mechanism 1 and the connecting piece 3. At the same time, the lamp head mechanism 1 can also form different lighting angles by rotating around the second rotating axis. It can adjust both the relative height of the lamp head mechanism 1 and the lighting angle of the lamp head mechanism 1, making the overall adjustment effect more flexible and versatile, and able to adapt to more different application scenarios.

[0030] Furthermore, the first damping mechanism includes a first locking member 41, a limiting cavity 31, and a connecting part 21. The limiting cavity 31 and the connecting part 21 are respectively disposed on the connecting member 3 and the movable swing arm 2. The first locking member 41 can tighten or loosen the limiting cavity 31 to increase or decrease the static friction between the limiting cavity 31 and the connecting part 21. The first damping mechanism has a simple structure. The first locking member 41 can also serve as a connection for the connecting member 3 and the movable swing arm 2. At the same time, by controlling the tightness of the first locking member 41, the damping effect between the limiting cavity 31 and the connecting part 21 can be controlled, thus adapting to the needs of more different users.

[0031] Furthermore, the first locking member 41 includes a first locking screw, the first rotating shaft is located at the central axis of the first locking screw, the first locking screw passes through the limiting cavity 31 and the connecting part 21 respectively, the first locking screw is connected and engaged with the side wall of the limiting cavity 31 through a threaded structure, the limiting cavity 31 can elastically deform, the first locking screw tightens the limiting cavity 31 by rotating forward or loosens it by rotating in reverse, and the user can easily adjust the damping effect by tightening or loosening the first locking screw.

[0032] Furthermore, the second damping mechanism includes a second locking member 42 and a connecting edge 12 and a limiting groove 22 that slide against each other. The limiting groove 22 and the connecting edge 12 are respectively disposed on the movable swing arm 2 and the lamp head mechanism 1. The second locking member 42 can make the lamp head mechanism 1 and the movable swing arm 2 move closer or further apart. When the lamp head mechanism 1 and the movable swing arm 2 move closer together, the contact area and static friction between the connecting edge 12 and the limiting groove 22 increase. Alternatively, when the lamp head mechanism 1 and the movable swing arm 2 move further apart, the contact area and static friction between the connecting edge 12 and the limiting groove 22 decrease. The structure of the second damping mechanism is simple. The second locking member 42 can also serve as an installation connection between the movable swing arm 2 and the lamp head mechanism 1. At the same time, the first locking member 41 controls the contact area and static friction between the connecting edge 12 and the limiting groove 22, thereby controlling the damping effect between the lamp head mechanism 1 and the movable swing arm 2, adapting to the needs of more different users.

[0033] Furthermore, the second locking component 42 includes a second locking screw, the second rotating shaft is located at the center of the second locking screw, the second locking screw passes through the tail end of the movable rocker arm 2 and is connected to the lamp head mechanism 1 through a threaded structure, the second locking screw can make the lamp head mechanism 1 move closer or further away from the movable rocker arm 2 by rotating forward or backward, and the user can easily adjust the damping effect by tightening or loosening the second locking screw.

[0034] Furthermore, corresponding movable swing rods 2 are connected to the left and right sides of the lamp head mechanism 1, and the two movable swing rods 2 are connected to the lamp head mechanism 1 to form a frame shape structure with left and right symmetry, which improves the stability of the overall structure of the gantry lamp.

[0035] Furthermore, the inner side of the connector 3 is hollow, and several convex ribs 32 are distributed on the inner side of the connector 3. The convex ribs 32 are distributed in an alternating manner, which can not only achieve the lightweight of the connector 3, but also ensure that it has good structural strength and is not easily deformed under stress.

[0036] Furthermore, the lamp head mechanism 1 includes a lamp housing and a lighting mechanism and an electrical control mechanism disposed within the lamp housing. The lighting mechanism and the electrical control mechanism are electrically connected. The lamp head mechanism 1 as a whole can form an independently working module, eliminating the need for wiring within the connector 3 or the movable swing arm 2, thus simplifying the overall structure of the gantry lamp.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
