DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] See also Figure 1-Figure 5A linear sliding module for office furniture includes a locking strip 500, a slide groove 501 and a sliding module. The locking strip 500 and the slide groove 501 are arranged in parallel. The sliding module is slidably arranged along the length direction of the locking strip 500 and the slide groove 501. It includes a mounting member 502 and a locking tongue 503 and an elastic member 504 arranged on the mounting member 502. The locking tongue 503 is movably connected to the mounting member 502 and is used for locking and cooperating with the locking strip 500. The elastic member 504 presses the locking tongue 503 toward the locking strip 500. The slide groove 501 is used to guide the locking tongue 503 to move so that the locking tongue 503 is unlocked from the locking strip 500 when the sliding module reaches the sliding limit state.
[0024] Continue reading Figure 2-Figure 4 In one embodiment of the present invention, the locking bar 500 is a ratchet bar structure, and the locking tongue 503 has a ratchet portion 5030 for engaging with the locking bar 500. The ratchet is an oblique tooth, and when the ratchet bar structure engages with the ratchet portion 5030, the ratchet structure enables the sliding module to move toward the inclined side of the ratchet, but not to move toward the other side.
[0025] Continue reading Figure 1-Figure 2 In one embodiment of the present utility model, the lock tongue 503 has a lock tongue shaft 5034 , and the lock tongue shaft 5034 is rotatably connected to the circular hole on the mounting member 502 .
[0026] Continue reading Figure 1-Figure 2 In one embodiment of the utility model, the mounting member 502 is a shell structure, the lock tongue 503 and the elastic member 504 are both arranged inside the mounting member 502, the elastic member 504 is preferably a torsion spring, and the mounting member 502 has a cylinder for mounting the elastic member 504, one end of the elastic member 504 is connected to the lock tongue 503 for squeezing the lock tongue 503.
[0027] Continue reading Figure 3-Figure 4 In one embodiment of the utility model, the lock tongue 503 has a locking groove 5031 and an unlocking groove 5032, and the locking groove 5031 and the unlocking groove 5032 are arranged adjacent to each other with a raised triangular slope therebetween. The locking groove 5031 is further away from the ratchet portion 5030 than the unlocking groove 5032.
[0028] When one end of the elastic member 504 is matched with the locking groove 5031, since the locking groove 5031 is far away from the ratchet portion 5030, the elastic member 504 can squeeze the lock tongue 503 toward the locking strip 500 for a greater distance, so that the lock tongue 503 is locked and matched with the locking strip 500. When one end of the elastic member 504 is matched with the unlocking groove 5032, since the unlocking groove 5032 is closer to the ratchet portion 5030, the distance that the elastic member 504 squeezes the lock tongue 503 toward the locking strip 500 is relatively short, and the lock tongue 503 will not be locked with the locking strip 500, that is, the elastic member 504 puts the lock tongue 503 in an unlocked state. The function of the slide groove 501 is to guide the lock tongue 503 to switch between the state in which the locking groove 5031 cooperates with the elastic member 504 and the state in which the unlocking groove 5032 cooperates with the elastic member 504, that is, to enable one end of the elastic member 504 to break through the triangular slope from the locking groove 5031 and enter the unlocking groove 5032, and to enable the elastic member 504 to break through the triangular slope from the unlocking groove 5032 and enter the locking groove 5031.
[0029] Continue reading Figure 1 and Figure 2 In one embodiment of the utility model, a lock tongue 503 has a lock tongue unlocking portion 5033, and the lock tongue unlocking portion 5033 is a convex column structure. The slide groove 501 is an annular structure, and a trapezoidal groove body is formed inside. The inclined surfaces on both sides of the trapezoidal groove body are guide surfaces 5010, and the guide surfaces 5010 are used to cooperate with the lock tongue unlocking portion 5033. When the lock tongue unlocking portion 5033 moves along the guide surfaces 5010, the guide surfaces 5010 guide the lock tongue unlocking portion 5033 to move in a direction away from the locking strip 500, thereby driving the lock tongue 503 to unlock the locking strip 500.
[0030] Continue reading Figure 1 and Figure 2 In one embodiment of the present invention, a limiting groove 5020 is provided on the mounting member 502 , and the limiting groove 5020 is slidably matched with the locking tongue unlocking portion 5033 .
[0031] In another embodiment of the present invention, the present invention further comprises a linear bracket, and the locking strip 500 and the slide groove 501 are arranged on the linear bracket.
[0032] by Figure 5 Take this as an example to introduce the method of using the utility model:
[0033] Figure 5The middle upper backrest is installed on the back bracket through a lifting seat, and the sliding module of the utility model is arranged on the lifting seat. The locking strip 500 and the slide groove 501 of the utility model are fixedly arranged on the back bracket. When the utility model is in an unlocked state, the upper backrest can be moved up and down, and the sliding module will move therewith. When the utility model is in a locked state, the height of the upper backrest is locked, and the upper backrest can only be moved in the inclined direction of the ratchet of the locking strip 500, and cannot be moved in the opposite direction. The ratchet of the locking strip 500 is inclined upward, so the upper backrest can only be moved upward.
[0034] Under normal circumstances, the ratchet portion 5030 of the lock tongue 503 is engaged with the locking strip 500, and the utility model is in a locked state. The elastic member 504 cooperates with the locking groove 5031. Due to the characteristics of the ratchet, the sliding module can drive the upper backrest and the lifting seat to slide in the ratchet tilt direction of the locking strip 500. When stopping, the elastic member 504 will make the ratchet portion 5030 and the locking strip 500 engage again. When the sliding module slides to the extreme position, the lock tongue unlocking portion 5033 encounters the guide surface 5010. Under the guidance of the guide surface 5010, the lock tongue unlocking portion 5033 and the lock tongue 503 move away from the entirety The locking strip 500 rotates in the direction of the locking strip 500, and as the locking tongue 503 rotates, the elastic member 504 breaks through the triangular slope and enters the unlocking groove 5032, thereby completing the unlocking and maintaining the locking tongue 504 in the unlocked state. At this time, the upper backrest and the lifting seat can be slid in the opposite direction to any position along with the sliding module, and the locking tongue unlocking portion 5033 of the locking tongue 503 drives the locking tongue 503 to rotate in the opposite direction under the guidance of the guide surface 5010, so that the elastic member 504 returns from the state of matching with the unlocking groove 5032 to the state of matching with the locking groove 5031. After the sliding module stops, under the action of the elastic member 504, the utility model is locked again.
[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
