Example 1:

referring to fig. 1, as a preferred embodiment of the present utility model, a sliding rod assembly is provided, which can be used in a frame of a crib as a side rail of the crib frame. The sliding rod assembly comprises a supporting rod 2 and a sliding rod 1, wherein the sliding rod 1 is slidably connected with the supporting rod 2 and has an up-and-down sliding stroke along the supporting rod 2, and in particular, in fig. 1, the sliding rod 1 has a sliding stroke along the supporting rod 2 in the direction of 'T1-T2'. In this embodiment, two support rods 2 are provided in opposite directions, a sliding rod 1 is provided between the two support rods 2, and both ends of the sliding rod 2 are slidably connected to the two support rods 1, respectively.

Referring to fig. 2-3, the sliding rod 1 comprises a sliding support 3 installed at the end of the rod body, a sliding block 31 is fixedly arranged on the sliding support 3, a sliding rail 21 is fixedly arranged on the supporting rod 2, and the sliding block 31 is slidably connected in the sliding rail 21 so as to realize sliding connection between the sliding rod 1 and the supporting rod 2. In this embodiment, the rod body of the sliding rod 1 is divided into two sections, and the two sections are connected by a lockable rotary joint 4, so that the sliding rod 1 can be folded or unfolded, and the sliding support 3 is rotatably connected with the rod body of the sliding rod 1. In other embodiments, if there is no requirement that the sliding rod be foldable, the sliding rod may be a single rod body, and the sliding support 3 is fixedly connected to the end of the rod body.

Referring to fig. 1-6, the support bar 2 in this embodiment acts as a sliding support, which is fixedly arranged relative to each other and thus acts as a fixing element. The slide bar 1 is slidable with respect to the support bar 2, and thus serves as a movable member. The locking mechanism 5 is installed between the fixed member (support lever 2) and the movable member (slide lever 1) for effecting locking or unlocking of the movement of the movable member with respect to the fixed member, in other words, the locking mechanism 5 is for effecting sliding locking or sliding unlocking of the slide lever 2. The locking mechanism 5 specifically includes a fixed slide 51, an unlocking key 52 and a latch member 54, where the fixed slide 51 is fixedly connected to the sliding support 3 through a threaded connection member, the fixed slide 51 is a hollow member and has a slide cavity, the unlocking key 52 is slidably fitted in the slide cavity of the fixed slide 51 up and down, the unlocking key 52 is provided with a containing cavity 523 for containing the latch member, the fixed slide 51 is provided with a first slide slot 512 extending left and right, a second slide slot 522 extending obliquely from top to bottom is provided on a side wall of the containing cavity 523, and a pin (not shown) passes through a through hole provided in the latch member 54 and is slidably connected in the first slide slot 512 and the second slide slot 522, so that the pin and the latch member 54 can be pushed to slide left and right along the first slide slot 512 by the oblique guiding action of the second slide slot 522 when the unlocking key 52 slides up and down. A pressing spring 55 (as a second elastic member) is provided at the upper end of the unlocking key 52, one end of the spring 55 acts on the slide mount 3, and the other end acts on the unlocking key 52 to apply a downward elastic force to the unlocking key 52. The support rod 2 is provided with a locking groove 22, and the locking groove 22 and the locking piece 54 are matched, so that the locking piece 54 can be elastically inserted and matched in the locking groove 22 to lock the sliding of the sliding rod 1 when moving up and down to the position corresponding to the locking groove 22. When the unlocking button 52 is pressed upward, the latch 54 can be disengaged from the locking groove 22, and the unlocking of the locking mechanism 5 is achieved. The locking groove 22 may be provided only in one or in plural from top to bottom, so as to lock the slide bar 1 at plural different heights.

The above structure of the lock mechanism 5 can be referred to another patent CN217814338U of the inventor.

In summary, the unlocking key 52 has a pressing stroke for unlocking the locking mechanism 5, but other locking mechanisms may be employed to realize the locking and unlocking functions, in addition to the specific locking mechanism 5 configuration proposed in the present embodiment, as long as the unlocking function is finally realized by one unlocking key.

As mentioned in the background, such a locking mechanism 5 with only one unlocking means (or only one unlocking step of pressing the unlocking key 52) is not secure. Therefore, this embodiment further improves the locking mechanism, referring to fig. 2-6, a slide way 521 is provided on the unlocking button 52, the push button 53 is slidably connected to the slide way 521 in the left-right direction, a blocking portion 511 is fixedly provided on the fixed slide way 51, the fixed slide way 51 is fixedly connected to the sliding support 3, and the blocking portion 511 is fixedly provided with respect to the sliding rod 1, so it is obvious that the blocking portion 511 may also be provided on the sliding support 3. The blocking portion 511 is a stopper structure integrally formed on the fixed rail 51 in this embodiment for ease of manufacture. A pressing spring 56 (as a first elastic member) is provided in the slide 521, and the pressing spring 56 acts on the push button 53 so as to protrude from the outer contour of the unlocking key 52 to oppose the blocking portion 511, so that the blocking portion 511 can block the movement of the push button 53 and the unlocking key 52 in the pressing stroke direction. When it is necessary to unlock the locking mechanism, the operations to be adopted are as follows: the push button 53 is pushed by a force applied transversely (left and right) to be staggered with the blocking part 511, and then the push button 53 and the unlocking key 52 assembled with the push button 53 are pushed vertically (upwards) to slide upwards, so that the unlocking of the locking mechanism 5 is realized. The compression spring 56 will further store energy during unlocking and act as a return member for the push button 53.

The locking mechanism 5 of the present embodiment requires two unlocking steps to unlock, and thus the security is high. In the present embodiment, the push button 53 has only one degree of freedom to slide laterally relative to the unlocking button 52, and the movement of the push button 53 in the up-down direction is restricted by the slide way 521, so that the push button 53 and the unlocking button 52 are pushed and interlocked with each other in the up-down direction. Therefore, although the lock mechanism 5 requires two unlocking steps for unlocking, the two unlocking steps are continuous, and the operator does not need to leave the push button 53 after pushing the push button 53 laterally, but only pushes the push button 53 upward immediately after changing the direction of application of force. In the whole unlocking process, the stress point is only one push button 53, and the operation is simple and convenient by one hand.

The compression springs 55, 56 may be replaced with other forms of resilient members, such as spring plates, tension springs, etc. in other embodiments, but the particular manner of installation may need to be adapted as will be generally understood by those skilled in the art.

In this embodiment, the blocking portion 511 is fixedly disposed at an outer side of the unlocking key 52, and the pressing spring 56 acts on the push button 53 to extend out of the outer contour of the unlocking key 52 to be opposite to the blocking portion 511, so as to limit the movement of the unlocking key 52. Of course, in other embodiments, the blocking portion 511 may be disposed inside the hollow unlocking key 52, but the installation of the push button 53 needs to be changed adaptively.

The sliding direction of the push button 53 is in the right-left direction perpendicular to the up-down direction in this embodiment, which is more convenient for the operator to apply force. In other embodiments, the sliding direction may be inclined, as long as the sliding direction intersects the vertical direction.

In addition to the sliding rod assembly of the present embodiment, the locking mechanism 5 with double locking function provided in the present embodiment may be used in other assembly structures of a fixed member and a movable member that need to be unlocked by a key, such as a door unlocked by a key.
