the lock sleeve 820 comprises a fixed disc 821, a movable cap 822, an elastic member 823 and a clamping rod 824, wherein the fixed disc 821 and the movable cap 822 are of a tubular structure with a single-side opening, the movable cap 822 is sleeved on the fixed disc 821, the elastic member 823 is arranged between the fixed disc 821 and the movable cap 822, the clamping rod 824 penetrates through the fixed disc 821 and the movable cap 822 along the radial direction of the fixed disc 821, the rod body of the clamping rod 824 is suspended in the inner cavity of the fixed disc 821, a movable groove 821a is formed in the position, penetrated by the clamping rod 824, of the fixed disc 821, the movable groove 821a extends along the axial direction of the fixed disc 821, the elastic member 823 provides elastic force to push the movable cap 822 to be far away from the fixed disc 821, and when the relative distance between the fixed disc 821 and the movable cap 822 is the farthest, the clamping rod 824 abuts against the lower groove wall of the movable groove 821a, as shown in fig. 8; when the movable cap 822 is pressed to slide the movable cap 822 along the movable groove 821a, and the fixed plate 821 is located at a closest distance from the movable cap 822, the locking lever 824 moves from the lower end of the movable groove 821a to the upper end of the movable groove 821a, as shown in fig. 12.

The locking procedure of the foot mount module 800 is described as follows:

before use, the lock sleeve 820 is required to be mounted on the preassembled position of the portable mobile lighting fixture 10, namely, the lock sleeve 820 is required to be fixed on a construction apparatus which is required to be fixed with the portable mobile lighting fixture 10, the fixing plate 821 is provided with a flange, the fixing plate 821 can be locked on the construction apparatus through the matching of the mounting hole on the flange and the bolt, and the opening of the fixing plate 821 faces outwards; the lock cylinder 810 is pulled up, and the protective rubber pad 530 presses the outer wall of the guide rod 812 to provide elastic force due to interference fit between the through hole 532 and the guide rod 812, so that the lock ring 813 is maintained in the receiving hole 531, as shown in fig. 8.

The portable mobile lighting fixture 10 is placed in the pre-installed position of the locomotive (or other construction equipment) and the locking collar 813 is aligned with the opening of the fixed plate 821, and at this time, the operating cap 811 is pressed to drive the lock cylinder 810 down along the through hole 532, so that the lock cylinder 810 enters the inner cavity of the fixed plate 821 until the lock cylinder 810 abuts against the locking bar 824 in the inner cavity of the fixed plate 821, as shown in fig. 9.

The operating cap 811 is then gripped and screwed so that the lock cylinder 810 is rotated, and when the notch of the rising groove 813a is aligned with the catch 824, the lock cylinder 810 can be further lowered and the catch 824 can be fitted into the rising groove 813a, as shown in fig. 10.

Further lowering of the lock cylinder 810 is performed by continuing to screw the operating cap 811, and the process blocking rod 824 slides along the rising groove 813a from the end of the lock cylinder 810 away from the guide rod 812 to the position close to the inflection point 813c until the lower end face of the operating cap 811 is attached to the supporting base 520, and after the lock cylinder 810 is lowered, the guide rod 812 changes position in the rising groove 813a, see fig. 10 and 11, and the guide rod 812 does not reach the inflection point 813 c.

When the operating cap 811 is continuously screwed, the lock cylinder 810 is blocked by the supporting foot seat 520 and does not descend any more, and the torsion applied by the user to the operating cap 811 acts on the clamping rod 824 through the ascending groove 813a, so that an upward pulling force is generated to drive the movable cap 822 to ascend relative to the fixed disc 821, at this time, the elastic member 823 is compressed, and the clamping rod 824 moves from the lower end of the movable groove 821a to the upper end of the movable groove 821 a; when the guide rod 812 is displaced to the inflection point 813c, the movable cap 822 is lifted up, as shown in fig. 12.

Continuing to screw the operation cap 811, the locking lever 824 enters the sinking groove 813b from the rising groove 813a, and since the sinking groove 813b extends in the opposite direction to the rising groove 813a, the locking lever 824 descends relative to the fixed plate 821, and at this time, the elastic member 823 starts to stretch to drive the movable cap 822 to descend relative to the fixed plate 821, and when the user removes the torsion force applied to the operation cap 811, the elastic member 823 provides an elastic force to hold the locking lever 824 in the sinking groove 813b, and the locking is completed, as shown in fig. 13.

Because the locking force between the lock cylinder 810 and the lock sleeve 820 is mainly the elastic force provided by the elastic piece 823, better buffering performance is provided between the lock cylinder 810 and the lock sleeve 820, vibration generated during operation of construction equipment can be fully absorbed, loosening caused by non-human intervention can be effectively avoided, and the portable lighting lamp 10 is more firmly fixed.

The unlocking steps of the above-mentioned foot rest fixing module 800 are as follows:

referring to fig. 13, when the foot fixing module 800 is in the locked state, the locking rod 824 is embedded in the sinking groove 813 b.

The operation cap 811 is rotated reversely, at this time, the locking lever 824 moves along the sinking groove 813b toward the inflection point 813c, the torsion applied to the operation cap 811 acts on the locking lever 824 through the groove wall of the sinking groove 813b, so that an upward pulling force is generated to drive the movable cap 822 to rise relative to the fixed plate 821, at this time, the elastic member 823 is compressed, and the locking lever 824 moves from the lower end of the movable groove 821a to the upper end of the movable groove 821 a; when the guide rod 812 is displaced to the inflection point 813c, the movable cap 822 is lifted up, as shown in fig. 12.

Referring to fig. 11 and 10 in sequence, after passing through the inflection point 813c, the locking lever 824 enters the rising groove 813a, and at this time, the elastic force exerted by the elastic member 823 and the torsion acting on the operating cap 811 drive the locking lever 824 to move from one end of the rising groove 813a, which is close to the guide rod 812, to the notch position of the rising groove 813a, and disengage from the rising groove 813a at the notch of the rising groove 813a, so that the lock cylinder 810 continuously rises in the process.

After the guide rod 812 is separated from the rising groove 813a, the lock cylinder 810 and the lock sleeve 820 are not connected with each other any more, the lock cylinder 810 can be pulled up by applying a vertical upward pulling force to the operation cap 811, the lock ring 813 is pulled out from the inner cavity of the fixed disc 821 and returns to the storage hole 531 at the bottom of the protection rubber cushion 530, at this time, after unlocking is completed, the portable lighting fixture 10 can be lifted up by holding the hand piece 510.

The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
