DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0025] In the description of the utility model, it is understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the utility model.

[0026] Please refer to Figure 1 , a kind of field surgical instrument lighting device is shown in the figure, its structure is similar to prior art device, mainly by a as main support and directly contact ground bottom plate 1 is constituted.

[0027] In addition, the bottom plate 1 is provided with support rod 2, the upper end of support rod 2 is provided with lighting lamp 3. This design supports lighting lamp 3 through support rod 2, and the vertical height of support rod 2 determines the height of lighting lamp 3. In this way, the height of lighting lamp 3 can be flexibly adjusted according to the actual demand of operation, so as to achieve the best lighting effect.

[0028] Meanwhile, lighting lamp 3 and support rod 2 are connected through damping rotation, and the angle of lighting lamp 3 is adjusted and controlled by using frictional resistance, so as to ensure that the irradiation direction of lighting lamp 3 meets the expectation. The design improves the flexibility of lighting lamp 3, and also ensures the stability and reliability of the lighting effect.

[0029] As Figure 1 And Figure 2 As can be seen, unlike prior art devices, in order to facilitate the adjustment of the vertical height of support rod 2, the device adopts a plurality of driven rods 201 arranged in an upper and lower row to form support rod 2.

[0030] The lowermost driven rod 201 is connected with the bottom plate 1 through rotation, and adjacent driven rods 201 are also connected through rotation. These driven rods 201 present a unique structure of broken line after vertical plane projection. This unique structure design enables support rod 2 to bend and adjust in multiple dimensions, that is, by controlling the angle between the center line of each driven rod 201 and the horizontal plane, the vertical height of support rod 2 is adjusted, so as to provide more flexible position adjustment space for lighting lamp 3.

[0031] Specifically, as Figure 2As shown, each driven rod 201 is fixedly connected with a half gear 202 on one side close to the adjacent driven rod 201, and the two adjacent half gears 202 are in meshing transmission with each other. Through the meshing transmission of the half gears 202, when one driven rod 201 rotates, it can drive the adjacent driven rod 201 to rotate, realizing the cooperative action between the plurality of driven rods 201, so that the device can realize the synchronous control of the angles between the center lines of the plurality of driven rods 201 and the horizontal plane by controlling the angle between the center line of a single driven rod 201 and the horizontal plane, thereby facilitating the overall adjustment of the shape and angle of the support rod 2.

[0032] In addition, the device is provided with a positioning frame 203 between the two adjacent driven rods 201, and a positioning shaft 206 with a horizontal center axis is arranged on the upper and lower sides of the positioning frame 203, and the positioning shaft 206 is rotatably connected with the corresponding half gear 202. The clever configuration of the positioning frame 203 and the positioning shaft 206 not only provides stable support and precise positioning for the half gear 202, but also ensures the stability and reliability of the transmission system, and effectively maintains the relative positional relationship between the driven rods 201.

[0033] As shown in Figure 2 , Figure 3 , Figure 4 To realize the control of the angle of the center line of a single driven rod 201, the device is provided with a height limiting mechanism between the lowermost driven rod 201 and the bottom plate 1.

[0034] Specifically, the height limiting mechanism includes a positioning rod 5. The lower end of the positioning rod 5 is rotatably connected with the bottom plate 1, and the upper end is fixedly connected with a limiting piece 4. This design enables the device to maintain stability and accuracy when adjusting the height.

[0035] Meanwhile, a corresponding limiting groove 204 is formed on the driven rod 201 for the limiting piece 4, and the limiting piece 4 is precisely inserted into the limiting groove 204. With the restraining action of the limiting groove 204, a stable triangular structure is naturally formed among the lowermost driven rod 201, the positioning rod 5 and the bottom plate 1, thereby effectively restraining and controlling the angle of the center line of the driven rod 201 by utilizing the inherent stability of the triangle.

[0036] Further, in order to fully realize the angle control of the center line of the limiting piece 4, the restraining limiting groove 204 of the device includes a moving groove 2042 and a positioning groove 2041, wherein the center line of the moving groove 2042 is parallel to the center line of the corresponding driven rod 201, and the relative position between the limiting piece 4 and the driven rod 201 can be changed through the moving groove 2042, that is, the angle of the center line of the driven rod 201 can be changed.

[0037] In addition, there are multiple positioning grooves 2041. These positioning grooves 2041 are located on the side of the moving groove 2042 away from the positioning rod 5 and are arranged at equal intervals along the length of the moving groove 2042. The limiting member 4 is embedded in the positioning groove 2041. With the help of the gravitational potential energy of the driven rod 201 itself, it is ensured that it is fully embedded and stable in the normal state and does not fall off. Thus, the relative position of the limiting member 4 and the driven rod 201 is precisely controlled by the positioning groove 2041.

[0038] Furthermore, in order to minimize the minimum height of the lighting fixture 3 in the folded state, a through groove 205 is provided on the lowest driven rod 201. The width of the through groove 205 is greater than the width of the positioning rod 5. In this way, in the folded state, the positioning rod 5 can be smoothly inserted into the through groove 205, avoiding travel interference with the driven rod 201 and ensuring that the center line of the driven rod 201 is nearly parallel to the horizontal plane.

[0039] Therefore, the constraint limiting member 4 of this device has a cylindrical structure, and a limiting groove 204 is respectively opened at both axial ends of the limiting member 4. This design not only enhances the stability and reliability of the limiting member 4, but also ensures its flexibility and convenience during use.

[0040] Furthermore, in order to adapt to the lateral width ratio of the lighting fixture 3 and the support rod 2, and to ensure that the device can fully support the lighting fixture 3 and prevent shaking during use, the upper side of the base plate 1 is constrained by the device, and a support rod 2 is set at each of the front and rear ends. The lighting fixture 3 is supported by the two support rods 2.

[0041] Therefore, this device has a follower rod 7 connected to the upper ends of the two support rods 2. The follower rod 7 is rotatably connected to the lighting fixture 3 through damping. This design not only gives the lighting fixture 3 excellent flexibility, but also ensures constant and reliable lighting effect.

[0042] Furthermore, such as Figure 5 As shown, in order to ensure the stability of this device in actual use, multiple positioning pins 6 are fixedly connected to the lower side of the base plate 1 along the vertical axis. The multiple positioning pins 6 are distributed in a rectangular array on the lower side of the base plate 1. This allows the positioning pins 6 to be inserted into the ground or other supports in the field environment, thereby significantly improving the overall stability and durability of the lighting device.

[0043] In practical applications, this utility model is as follows:

[0044] Lighting fixture 3 angle adjustment mechanism: When it is necessary to adjust the angle of the lighting fixture 3, thanks to the precise damping rotation connection design between the lighting fixture 3 and the follower rod 7, users can easily achieve fine control of the lighting angle.

[0045] The height adjusting mechanism of the lighting lamp 3: when adjusting the height of the lighting lamp 3, by rotating the lowermost driven rod 201 (i.e. lifting the lighting lamp 3 upward), the multiple driven rods 201 will rotate cooperatively by the meshing transmission principle of the half gear 202, so as to realize the rapid adjustment of the height of the lighting lamp 3. In this process, the limiting piece 4 on the positioning rod 5 will move in the moving groove 2042. When the lighting lamp 3 reaches the predetermined height, the user releases the pulling force on the lighting lamp 3, the driven rod 201 rotates downward due to the gravity (the included angle between the driven rod 201 and the horizontal plane decreases), and the limiting piece 4 is automatically embedded in the positioning groove 2041, at this time, the height of the lighting lamp 3 is fixed, which ensures the stability of the adjustment.

[0046] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
