Description

Technical Field

[0001] The utility model relates to the technical field of gas springs, in particular to a bidirectional rigid locking gas spring. Background Art

[0002] Bidirectional gas springs can achieve extension and compression in two directions and provide elastic support force, but existing bidirectional gas springs are difficult to maintain stability when stretched for a long time.

[0003] The reason for the instability is that when the piston is extended to fix the component in the desired position for a long time, the angle or position of the component may change due to slight external forces such as vibration or collision, thereby affecting the user experience.

[0004] In summary, we propose a bidirectional rigid locking gas spring to solve the above-mentioned problems. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-4A bidirectional rigid locking gas spring comprises a cylinder 1, wherein two retractable piston rods 11 are arranged inside the cylinder 1, and the front end of the piston rod 11 is fixedly connected to the top 12, and the upper end of the cylinder 1 is fixedly connected to the locking mechanism 2, and the locking mechanism 2 is provided with two locking rods 21 which follow the extension and contraction of the piston rod 11. The upper surface of the locking rod 21 is provided with a plurality of semicircular locking grooves 211, and the middle of the upper surface of the locking mechanism 2 is provided with a card slot 22, and the card slot 22 has the same shape as the locking groove 211. When the locking groove 211 matches the card slot 22, the two can be magnetically connected with a locking piece 3 inside. The locking mechanism 2 and the locking rod 21 are made of pure iron. When in use, when the piston rod 11 is extended to the desired position, the locking rod 21 is fixedly connected to the top 12, and the upper end of the cylinder 1 is fixedly connected to the locking mechanism 2. When the locking mechanism 2 and the locking rod 21 are in a fixed position and need to remain stable for a long time, the staff can insert the locking piece 3 into the locking groove 211 and the card slot 22. After insertion, the magnetic block 32 at the lower end of the locking piece 3 is magnetically connected with the locking mechanism 2 and the locking rod 21, and then firmly inserted into the locking groove 211 and the card slot 22. At this time, the locking rod 21 is locked, and the top 12 is locked by the fixing plate 121, so that the piston rod 11 remains in a rigid state, thereby greatly improving the stability, and the angle or position will not change due to external force. The insertion of the locking piece 3 can lock the two piston rods 11 synchronously. Even if the two piston rods 11 extend to different lengths, they can be locked synchronously as long as the locking groove 211 corresponds to the card slot 22.

[0020] Furthermore, a fixed plate 121 is fixedly connected to the outer surface of the top 12, and the front end of the locking rod 21 is against the fixed plate 121 and fixedly connected to the fixed plate 121. During use, when the piston rod 11 is extended, the locking rod 21 can be driven to extend along with it through the fixed plate 121. The locking rod 21 follows the piston rod 11 to extend and retract inside the locking mechanism 2 to facilitate subsequent locking.

[0021] Furthermore, fixed rings 13 are fixedly mounted on both sides of the outer surface of the cylinder 1, and the outer surface of the fixed ring 13 is fixedly connected to the lower end of the locking mechanism 2. When in use, the locking mechanism 2 is fixedly mounted on the fixed ring 13 and fixedly mounted on the upper end of the cylinder 1 through the fixed ring 13.

[0022] Furthermore, a handle 31 is fixedly connected to the upper surface of the locking piece 3, and a magnet 32 ​​is fixedly connected to the lower surface. When the magnet 32 ​​is inserted into the lock slot 211 and the card slot 22, it is magnetically fixed to the locking mechanism 2 and the locking rod 21. When in use, the design of the handle 31 can make it easier for the staff to operate the locking piece 3. When rigid locking is not required, just hold the handle 31 and pull up the locking piece 3 together with the magnet 32.

[0023] Working principle: The utility model is a bidirectional rigid locking gas spring. When in use, when the piston rod 11 is extended into place and needs to be maintained for a long time, the locking piece 3 is inserted into the lock groove 211 and the card slot 22, so that the magnetic block 32 is magnetically connected and fixed with the locking mechanism 2 and the locking rod 21 cast from pure iron. The insertion of the locking piece 3 locks the locking rod 21, and the fixed disk 121 locks the top 12, thereby maintaining the rigidity of the piston rod 11, greatly improving the stability, and making it difficult for external force to change its angle and position. When unlocking, hold the handle 31 to pull out the locking piece 3 together with the magnetic block 32, then the locking rod 21 is unlocked, and the piston rod 11 resumes its telescopic function.
