As shown in fig. 1 to 3, according to an embodiment of the present utility model, there is provided a mechanical telescopic rod with an illumination function, the telescopic rod includes a telescopic rod body 1, and the body 1 is sequentially sleeved with a housing 101, a first rod body 102 and a second rod body 103 from outside to inside, and the sleeved structure realizes a basic telescopic function of the present application. For ease of illustration, the body 1 is extensible with one side as the top and the other side as the bottom for positional relationship. In contrast, the housing 101, the first stick body 102, and the second stick body 103 are respectively provided with a top and a bottom corresponding to the body 1. Wherein, the top of the second stick body 103 is provided with a replaceable connecting piece 3, and the telescopic stick is combined with other tools through the connecting piece 3 and provides an extended requirement for the other tools. In this embodiment, the connecting member 3 is screwed to the second stick body 103.

In order to maintain or release the telescopic state of the telescopic rod, a locking assembly and a bolt 104 matched with the locking assembly are arranged in the body 1. The locking assembly comprises a spring assembly 106, and at least one spring assembly 106 is arranged on the first rod 102 and the second rod 103. The latch 104 includes a pressing portion 10401 and a plunger 10402, where the plunger 10402 is inserted from the bottom of the body 1 along the axis of the body 1, and cooperates with the above-mentioned elastic piece assembly 106 to lock or release the first stick body 102 and the second stick body 103 on the body 1 relatively.

Specifically, as shown in fig. 4 to 6, taking the first stick body 102 as an example, the elastic piece assembly 106 includes two elastic pieces 10601 arranged opposite to each other, the elastic pieces 10601 are provided with a semicircular drum portion 10602 and a guiding portion 10603, the guiding portion 10603 is provided with a circular guiding hole 10604, and a tensioning spring 10606 is disposed between the two elastic pieces 10601. The side wall of the bottom of the first stick body 102 is provided with two guiding holes 10605 matching with the elastic pieces 10601, the elastic pieces 10601 are disposed in the guiding holes 10605, and the drum portion 10602 is disposed outwards. Grooves 10607 are formed on the top inner wall of the housing 201 and cooperate with the drum portion 10602 of the elastic sheet 10601, and preferably, the grooves 10607 are annular. The cooperation of the drum 10602 and the groove 10607 performs a locking function. In the locked state, the two elastic sheets 10601 are sprung outwards in the radial direction under the action of the spring 10606, so that the drum portions 10602 of the elastic sheets 10601 are embedded into the grooves 10607, and the centers of the guide holes 10605 of the two elastic sheets 10601 are deviated from the axle center of the first stick body 102. At the time of unlocking, the plunger 10402 is inserted into the guide hole 10605. Under the action of the plunger 10402, the two elastic pieces 10601 move radially inward, and the drum portion 10602 of the elastic piece 10601 is disengaged from the groove 10607, thereby completing the unlocking operation.

In some embodiments, the grooves 10607 may be provided along the axis, so that the stick body may be provided with a plurality of locking points during the retraction process, so as to better control the retraction length.

A first spring 105 is sleeved outside the plunger 10402 between the pressing portion 10401 and the bottom end of the housing 101, one end of the first spring 105 abuts against the bottom of the housing 101, and the other end abuts against the pressing portion 10401. The first spring 105 is used for automatically resetting after the latch 104 is unlocked, so that the situation that the plunger 10402 remains in the spring assembly 106 when the first rod 102 or the second rod 103 is in a locking position and needs to be locked, for example, is avoided, and the spring assembly 106 cannot realize the locking function.

After assembly, sleeve 205 may reciprocate within first pocket 20101 and second pocket 20102. One end of the sleeve 205, which is close to the second cavity 20102, is provided with a convex ring 20501, the convex ring 20501 is in clearance fit with the inner wall of the second cavity 20102, and the outer diameter of the convex ring 20501 is larger than the inner diameter of the first cavity 20101. Thus, the junction of the first pocket 20101 and the second pocket 20102 defines a boundary of one direction of motion of the male ring 20501. One end of the pressing member 204 is provided with an annular connecting portion 20401 protruding outwards, the pressing member 204 directly abuts against the second cavity 20102 after entering the third cavity 20103, and the circuit assembly 202 is placed in the third cavity 20103 and the circuit assembly 202 and the pressing member 204 are fixed through the lamp cover 203. The other movement boundary of the male ring 20501 is defined by the attachment portion 20401 of the compression member 204 after assembly. When the sleeve 205 reciprocates relative to the housing 201, the body of the follower 204 will extend into the sleeve 205 and, opposite, the body of the follower 204 will reciprocate within the sleeve 205.

In some embodiments, the connecting portion 20401 of the pressing element 204 is provided with a first external thread, and the end portion of the second cavity 20102 near the side of the third cavity 20103 is provided with a first internal thread matching the connecting portion 20401.

In some embodiments, the battery is a chargeable and dischargeable storage battery, and the circuit assembly 202 is provided with a charging and discharging interface, and the interface is connected to the circuit board. Corresponding openings are reserved on the housing 201 for the switch key 207 and the interface.

In order to improve the waterproof performance of the lighting device 2, waterproof gaskets, which are usually made of rubber, are disposed between the second cavity 20102 and the pressing member 204, and between the circuit assembly 202 and the lamp cover 203.

The lighting device 2 is detachably disposed at the bottom of the telescopic rod body 1, in some embodiments, the bottom of the housing 101 of the body 1 is provided with a second external thread, and the inner wall of the sleeve 205, which is far away from one end of the convex ring 20501, is provided with a second internal thread, and the second external thread is connected with the second internal thread in a matching manner, so that the lighting device 2 is mounted on the body 1. At this time, the sleeve 205 is integrally connected with the housing 101 of the body 1.

In use, when extended, the first and second sticks 102, 103 may be pulled outwardly. The first stick body 102 and/or the second stick body 103 are locked under the set position and the action of the spring assembly 106. If it is desired to retract the lighting device 2, the sleeve 205 is relatively at rest, and thus the housing 201, the presser 204, etc. of the lighting device 2 will move inwardly. The compression member 204 applies pressure to the latch 104 and the plunger 10402 inserts into the spring assembly 106 to unlock it. The above operations are repeatedly performed, and the first stick body 102 and/or the second stick body 103 are sequentially unlocked and then retracted.

In some embodiments, for the above operation, during retraction, the lighting device 2 will be reset simultaneously with the reset of the latch 104 by the first spring 105. However, in order to achieve a better effect, the second spring 206 is sleeved outside the main body of the pressing member 204, one end of the second spring 206 abuts against the convex ring 20501 of the sleeve 205, and the other end abuts against the connecting portion 20401 of the pressing member 204. In this way, the sleeve 205 will remain on the side close to the first cavity all the time without the effect of external force and will allow a quick resetting of the lighting device 2 during the retraction operation.

The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
