Description

Technical Field

[0001] The utility model relates to the technical field of telescopic springs, in particular to a durable telescopic spring. Background Art

[0002] A spring is a mechanical part that works by utilizing elasticity. It deforms under the action of an external force and returns to its original shape when the force is removed. There are many types of springs, mainly classified by shape: coil springs, scroll springs, leaf springs, and special-shaped springs. A telescopic spring is a type of spring whose main feature is its ability to expand and contract in length under the action of an external force and return to its original length when the force is removed. This type of spring is widely used in many fields.

[0003] Publication number CN204647103U discloses a telescopic spring device, in which a first engaging portion and a second engaging portion limit the maximum telescopic length of a first telescopic rod and a second telescopic rod, thereby limiting the maximum tensile length of the spring; a second spring and a support plate inside the second telescopic rod limit the maximum compression length of the first telescopic rod and the second telescopic rod, and have a buffering effect, thereby protecting the spring from damage due to excessive compression; however, the elasticity of the telescopic spring may change in a high or low temperature environment, resulting in the telescopic spring failing to achieve the desired effect, which is quite inconvenient. For this reason, we propose a durable telescopic spring. Utility Model Content

[0004] The purpose of the utility model is to provide a durable telescopic spring.

[0005] In order to solve the problems raised in the above background technology, the utility model provides the following technical solutions: a durable telescopic spring, comprising a fixed end, an upper end of the fixed end is equipped with an adjusting plate, one end of the fixed end is equipped with a turning handle, one end of the turning handle is equipped with a rotating column, one end of the rotating column is equipped with a first bevel gear, a stabilizing block is installed on one side of the inner wall of the fixed end, one end of the first bevel gear is provided with a second bevel gear, the center of the upper end of the second bevel gear is equipped with a spiral rod, the upper end of the fixed end is equipped with a first mounting column near the four corners, and the side wall of the first mounting column is provided with a positioning groove near the upper side;

[0006] A first mounting plate is installed on the upper end of the adjustment plate, a spring is provided at the center of the upper end of the first mounting plate, a second mounting plate is installed on the upper end of the spring, second mounting columns are installed at the four corners of the upper end of the first mounting plate, and a movable end is installed on the upper end of the second mounting column.

[0007] Preferably, the handle is fixedly connected to the rotating column, and the rotating column passes through the fixed end and the stabilizing block, and the rotating column is fixedly connected to the first bevel gear.

[0008] Preferably, the first bevel gear is meshed with the second bevel gear, and both the first bevel gear and the second bevel gear are located inside the fixed end.

[0009] Preferably, the second bevel gear is fixedly connected to the spiral rod, the spiral rod passes through the fixed end, the adjustment plate and the first mounting plate, and the spiral rod is threadedly connected to the adjustment plate.

[0010] Preferably, a fixing block is installed on the inner side of the first mounting column, a first fixing plate and a second fixing plate are installed on both sides of the fixing block respectively, a first mounting block is installed on both sides of the first fixing plate and the second fixing plate, a second mounting block is installed on both sides of the fixing block, a first bolt is provided on the upper end of the first mounting block, and limiting plates are installed on both sides of the fixing block, and second bolts are provided through the surface of each limiting plate.

[0011] Preferably, the fixing block is slidably connected to the first mounting column, and the first fixing plate and the second fixing plate are movably connected to the positioning groove.

[0012] Preferably, the first bolt passes through the first mounting block and the second mounting block, and the first bolt is threadedly connected to the first mounting block and the second mounting block.

[0013] The above technical solution is adopted, by rotating the handle, so that the handle drives the second bevel gear to rotate under the cooperation of the rotating column and the first bevel gear. At this time, when the second bevel gear rotates, it drives the adjusting plate to slide upward on the first mounting column through the spiral rod. Then, when the adjusting plate slides, it pushes the first mounting plate to move together, thereby reducing the distance between the first mounting plate and the second mounting plate, increasing the elasticity of the spring, and vice versa, reducing the elasticity of the spring. When the elasticity is adjusted to the required level, it stops, so that the durable telescopic spring can adjust the elasticity of the spring to adapt to different working environments.

[0014] By adopting the above technical solution, the restriction of the limiting plate on the first bolt is cancelled by loosening the second bolt, and then the first bolt is loosened to eliminate the fixation between the first mounting block and the second mounting block, and then the first fixing plate and the second fixing plate are pulled to separate the first fixing plate and the second fixing plate from the fixing block, and then the fixing block is pulled to make the fixing block slide out from the first mounting post, so that the obstruction of the fixing block to the second mounting plate disappears, and then the second mounting plate is pulled to pull the spring and the first mounting plate out, thereby completing the disassembly, and vice versa, and the installation is completed, and the cooperation of the second bolt and the limiting plate prevents the first bolt from rotating during use, so that the durable telescopic spring can quickly load and unload the fixing block and the first mounting post, making it convenient to replace the internal spring.
