[0044] like Figure 1-16 As shown, in one embodiment of the present invention, a field surgical lamp is provided, including a base 10, a storage box 20, a lamp pole 30, a lamp head 40, a telescopic rod 50, a magnet 60, four limit frames 70, a foot pedal 80, four rotating components 90, a first locking component 110 and a second locking component 120.

[0045] Four supporting legs 11 are respectively provided at the four corners of the base 10, and universal wheels 12 are installed at the bottom of the supporting legs 11. The storage box 20 is installed on the base 10, and the lamp pole 30 is a multi-stage detachable structure. The lamp pole 30 is inserted into the storage box 20 and can be stored in the storage box 20. The lamp head 40 is connected to the lamp pole 30 and can be stored in the storage box 20.

[0046] The telescopic rod 50 is installed on the base 10, and the movable end of the telescopic rod 50 can extend out of the base 10. The magnet 60 is fixed to the movable end of the telescopic rod 50. The four limit frames 70 correspond to the four supporting feet 11 respectively. The limit frames 70 are rotatably arranged on the supporting feet 11 and can abut against the ground. The foot pedal 80 is located on one side of the base 10, and the foot pedal 80 can move vertically. The four rotating components 90 correspond to the four limit frames 70 respectively. The rotating components 90 are used to drive the limit frames 70 to rotate until they abut against the ground after the foot pedal 80 moves down, or the rotating components 90 are used to drive the limit frames 70 to rotate after the foot pedal 80 moves up so that they are suspended.

[0047] The transmission assembly 100 is used for transmission connection between the foot pedal 80 and the four rotating assemblies 90. The first locking assembly 110 is used for locking the telescopic rod 50 after the foot pedal 80 moves down, or for unlocking the movable end of the telescopic rod 50 after the foot pedal 80 moves up. The second locking assembly 120 is used for locking the foot pedal 80 after the foot pedal 80 moves down, or for unlocking the foot pedal 80.

[0048] When the field operation lamp is used, the user first takes out the lamp pole 30 and the lamp head 40 from the storage box 20 and assembles them. After the assembly, the lamp pole 30 is inserted into the storage box 20 to fix the lamp pole 30. The plug-in fixing method of the lamp pole 30 and the storage box 20, and the connection method of the lamp head 40 and the lamp pole 30 are prior arts, which will not be described in detail in this embodiment.

[0049] Next, the user pulls out the movable end of the telescopic rod 50 to make the magnet 60 magnetically attracted to the bed frame of the operating bed. Then, the user steps on the foot pedal 80 to move the foot pedal 80 downward. During the downward movement of the foot pedal 80, the four rotating components 90 drive the limit frame 70 to rotate through the transmission component 100 until the limit frame 70 abuts against the ground (see Fig.16 ), thus, under the obstruction of the four limiting frames 70, the base 10 will not move easily, thus achieving the locking of the base 10.

[0050] When the foot pedal 80 moves downward, the first locking assembly 110 will lock the movable end of the telescopic rod 50. After the foot pedal 80 is lowered into place, the second locking assembly 120 will lock the foot pedal 80. In this way, the base 10 is locked and the movable end of the telescopic rod 50 is locked simultaneously.

[0051] The present embodiment discloses a field surgical lamp. After the magnet 60 magnetically attracts the bed frame of the operating bed, the base 10 and the movable end of the telescopic rod 50 can be locked by stepping on the foot pedal 80. Under the joint action of the magnet 60 and the four limit frames 70, the base 10 can be prevented from moving and the base 10 can be firmly connected to the operating bed, thereby improving the locking effect of the base 10 and the stability of the surgical lamp. At the same time, after the telescopic rod 50 is connected to the bed frame of the operating bed via the magnet 60, the position of the telescopic rod 50 is close to the ground, which reduces the obstruction to the doctor during the operation. In addition, since the lamp pole 30 and the lamp head 40 can be stored in the storage box 20, it is convenient to modularize the storage of the surgical lamp and improve the equipment deployment efficiency.

[0052] In one embodiment, the rotating assembly 90 includes a first gear 91, a first rack 92, a first pull rope 93 and a first reset member 94. The first gear 91 is connected to the limiting frame 70 and arranged coaxially. The first rack 92 is slidably fitted in the support leg 11 and meshes with the first gear 91. One end of the first pull rope 93 is connected to the first rack 92. The first reset member 94 is used to apply elastic force to the first rack 92 to reset the first rack 92 after it moves. When the foot pedal 80 moves downward, the transmission assembly 100 pulls the four first pull ropes 93 respectively to rotate the limiting frame 70 until it abuts against the ground.

[0053] Furthermore, the base 10 is provided with a first cavity, the support leg 11 is provided with a second cavity, the second cavity is connected to the first cavity, and the rotating assembly 90 is provided in the second cavity. The transmission assembly 100 includes a second rack 101, a first shaft 102, a second reset member 103 and a second gear 104. The second rack 101 is vertically slidably fitted in the first cavity and connected to the foot pedal 80. The first shaft 102 is rotatably provided in the first cavity, and the first pull rope 93 is wound around the first shaft 102 (see Figure 7 , the winding directions of two adjacent first pull ropes 93 are opposite). The second gear 104 is fixed on the first shaft 102 and meshes with the second rack 101. The second reset member 103 is used to apply elastic force to the second rack 101 to reset it after the foot pedal 80 moves downward. The second locking assembly 120 is used to lock the second rack 101 after the foot pedal 80 moves downward, or to unlock the second rack 101.

[0054] When the user steps on the pedal 80, the second rack 101 will also move downward synchronously, and driven by the second gear 104, the first shaft 102 will rotate, so that it can reel in the four first pull ropes 93. In this way, the first pull rope 93 will pull the first rack 92 to move, and drive the limit frame 70 to rotate through the first gear 91 until it abuts against the ground. At the same time, the first locking assembly 110 will lock the movable end of the telescopic rod 50, and the second locking assembly 120 will also lock the second rack 101, so as to maintain the locking state of the movable end of the telescopic rod 50 and the base 10.

[0055] During the movement of the first rack 92 and the second rack 101, the first reset member 94 applies a reset elastic force to the first rack 92, and the second reset member 103 applies a reset elastic force to the second rack 101. Therefore, after the user uses the second locking assembly 120 to release the locking state of the second rack 101, the first rack 92 and the second rack 101 are reset by the first reset member 94 and the second reset member 103, so that the limit frame 70 rotates off the ground and hangs in the air, and the foot pedal 80 also moves up and resets, and the first locking assembly 110 also releases the lock on the movable end of the telescopic rod 50. In this way, the user can move the surgical light after the magnet 60 is separated from the bed frame of the operating bed.

[0056] In one embodiment, the transmission assembly 100 further includes a second shaft 105 and a third gear 106. The second shaft 105 is rotatably disposed in the second cavity, and the second shaft 105 is arranged parallel to the first shaft 102. The third gear 106 is fixed on the second shaft 105, and the third gear 106 is disposed between the second rack 101 and the second gear 104. The third gear 106 is meshed with the second rack 101 and the second gear 104, respectively, and the diameter of the third gear 106 is greater than the diameter of the second gear 104.

[0057] Since the second rack 101 and the second gear 104 need to be transmitted through the third gear 106, and the diameter of the second gear 104 is smaller than the diameter of the third gear 106, therefore, by utilizing the speed-increasing principle of the large gear driving the small gear to rotate, the user only needs to step on the pedal 80 and move it downward a short distance to achieve rapid rotation of the rotating limit frame 70, thereby reducing the stroke of the pedal 80 and facilitating operation.

[0058] In one embodiment, see Figure 8-13 The telescopic rod 50 includes a first rod body 51 and a second rod body 52. ​​The first rod body 51 is arranged on the base 10, and the second rod body 52 is telescopically fitted in the first rod body 51. The magnet 60 is arranged at one end of the second rod body 52. ​​The outer wall of the second rod body 52 is provided with a limiting plate 53. The limiting plate 53 extends along the length direction of the second rod, and the limiting plate 53 extends out of the first rod body 51.

[0059] The first locking assembly 110 includes a first housing 111, a driving block 112, a second pull rope 113, a third reset member 114 and two clamping blocks 115. The first housing 111 is disposed on the first rod 51 and is located outside the base 10. The driving block 112 is slidably fitted in the first housing 111 along a direction parallel to the length direction of the first rod 51. The two clamping blocks 115 are slidably fitted on the first rod 51 and are located on both sides of the limiting plate 53. The sliding direction of the clamping blocks 115 is perpendicular to the sliding direction of the driving blocks 112. After the driving block 112 moves, the two clamping blocks 115 can move closer to or farther from each other.

[0060] One end of the second pull rope 113 is connected to the driving block 112, and the other end of the second pull rope 113 is extended into the first cavity and connected to the second rack 101. The third reset member 114 is arranged in the first housing 111, and the third reset member 114 is used to apply elastic force to the driving block 112, so that the driving block 112 is reset after moving toward the base 10. Specifically, two pins 116 are arranged on the driving block 112, and a first hole 117 is arranged on the clamping block 115. The end of the first hole 117 close to the base 10 is inclined toward the side away from the limiting plate 53, and each pin 116 is slidably fitted in a corresponding first hole 117.

[0061] When the second rack 101 moves downward, the second pull rope 113 is pulled, so that the second pull rope 113 pulls the driving block 112 to move toward the base 10, and the pin 116 pushes the inner wall of the first hole 117, so that the two clamping blocks 115 move closer to each other until the two clamping blocks 115 clamp the limit plate 53. In this way, the second rod body 52 cannot extend or retract relative to the first rod body 51, thereby achieving the locking of the second rod body 52.

[0062] When the driving block 112 moves toward the base 10, the third reset member 114 will further deform. Therefore, when the second rack 101 moves upward, the third reset member 114 will pull the driving block 112 to move toward the magnet 60, and the two pins 116 on the driving block 112 will also drive the two clamping blocks 115 to move away from each other, thereby releasing the limit plate 53, and thus achieving the unlocking operation of the second rod body 52.

[0063] In one embodiment, a support 13 is provided in the first cavity, and a stopper 118 is provided after the second pull rope 113 moves through the support 13, and the second pull rope 113 is in a tightened state. The first locking assembly 110 further includes a third pull rope 119, one end of the third pull rope 119 is connected to the stopper 118, and the other end of the third pull rope 119 is connected to the second rack 101, and the third pull rope 119 is in a relaxed state.

[0064] Since the distance between the clamping block 115 and the limiting plate 53 is very small, it is only necessary to move the clamping block 115 a short distance. Therefore, the above-mentioned structural design makes it possible for the third pull rope 119 to be in a taut state only after the second rack 101 moves downward a certain distance, so that the third pull rope 119 can pull the second pull rope 113 to move the driving block 112, thus satisfying the requirement that the two clamping blocks 115 can clamp the limiting plate 53 by moving a short distance.

[0065] In one embodiment, see Fig.14 and 15 The second locking assembly 120 includes a second housing 121, a lock pin 122, a fourth reset member 123, a connecting column 124 and a push block 125. The second housing 121 is disposed in the first cavity, the lock pin 122 movably penetrates the second housing 121, the second rack 101 is provided with a second hole 107 that can cooperate with the lock pin 122, the outer wall of the lock pin 122 located in the second housing 121 is provided with a limiting flange 126, the fourth reset member 123 is sleeved on the lock pin 122 and is located in the second housing 121. The connecting column 124 is arranged in parallel with the lock pin 122, one end of the connecting column 124 is connected to one end of the lock pin 122 away from the second rack 101, the other end of the connecting column 124 extends out of the base 10 and is connected to the push block 125, and the push block 125 is arranged on the same side as the foot pedal 80.

[0066] When the second rack 101 is in the initial state, the locking pin 122 is in contact with the second rack 101. When the second rack 101 moves downward, when the second hole 107 is aligned with the locking pin 122, the fourth reset member 123 pushes the limiting flange 126, so that the locking pin 122 is inserted into the second hole 107. In this way, the second rack 101 is locked, and the limiting frame 70 and the second rod body 52 are also in a locked state.

[0067] When unlocking is required, the user only needs to kick the push block 125, and the connecting column 124 will drive the lock pin 122 to exit the second hole 107. In this way, under the action of the second reset member 103, the second rack 101 will be driven to move upward, and the first reset member 94 will also pull the first rack 92 to reset, thereby driving the limit frame 70 to rotate to the suspended position. The third reset member 114 will also pull the driving block 112 to reset, and the driving block 112 will also drive the two clamping blocks 115 to move away from each other, thereby releasing the lock on the second rod body 52.
