For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0020] Please refer to Figure 1 - Figure 2 , Figure 1 - Figure 2Schematically shows a preload adjustment assembly for a bicycle shock absorber according to the present utility model.
[0021] In an embodiment of the present utility model, which is applied to a preload adjustment assembly for a bicycle shock absorber, it is characterized in that it includes an outer cover 1 and a housing 6, an adjustment strut 2, an adjustment screw 3, and a spring 7 disposed inside the outer cover 1 and the housing 6. The adjustment strut 2 is disposed at the top end inside the outer cover 1. A spring 7 is connected to the lower end of the adjustment strut 2, and the spring 7 is fixed to the bottom of the housing 6.
[0022] The adjustment strut 2 is threadedly connected to the adjustment screw 3. The adjustment strut 2 is provided with a protrusion corresponding to the groove of the outer cover 1, and the protrusion restricts the rotation between the adjustment strut 2 and the outer cover 1.
[0023] Among them, the adjustment strut 2 is responsible for supporting the spring 7.
[0024] Among them, the spring 7 adopts a coil spring. The more it is compressed, the greater the elastic force generated by the spring 7. Therefore, the softness and hardness of the shock absorber are determined by the elastic force of the spring 7.
[0025] Furthermore, the outer cover 1 is provided with a middle hole, and the head of the adjustment screw 3 passes through the outer cover 1 with the middle hole.
[0026] Among them, the threaded part of the adjustment screw 3 is larger than the middle hole of the outer cover 1, ensuring that during the adjustment process, the adjustment screw 3 can smoothly pass through the outer cover 1, and at the same time, it can also increase the relative stability between the adjustment screw 3 and the outer cover 1.
[0027] Among them, the threaded part being larger than the middle hole can increase the friction with the outer cover 1 and improve the stability.
[0028] Furthermore, the end of the adjustment screw 3 is provided with a first groove with a rubber ring. The first groove cooperates with the middle hole to form a seal, and the middle hole has a second groove corresponding to the rubber ring, which makes the adjustment screw 3 not easy to fall off and does not hinder rotation.
[0029] Among them, in another embodiment of the present utility model, an elastic retaining ring can be installed at the end of the adjustment screw 3 instead of the rubber ring to axially fix the elastic retaining ring to the outer cover 1.
[0030] Furthermore, it also includes an adjustment knob 4 and a screw 5. The adjustment knob 4 is fixedly connected to the head of the adjustment screw 3 through the screw 5.
[0031] Among them, the adjustment knob 4 drives the adjustment screw 3 to rotate.
[0032] Among them, the protrusion restriction between the adjustment strut 2 and the outer cover 1 makes the adjustment strut 2 can only move along the thread direction of the adjustment screw 3. At this time, the adjustment strut 2 extends or retracts the total length of the adjustment spring 7 in the housing 6 under the action of the thread.
[0033] Furthermore, the outer cover 1 and the outer shell 6 are rigidly connected by threads.
[0034] Among them, the use of rigid threaded connection makes the assembly and disassembly of the outer shell 6 and the outer cover 1 simple and easy, without the need to use special tools or complex operations.
[0035] Among them, the tightened threaded connection helps to lock the adjustment position.
[0036] The beneficial effects of the present utility model: The present utility model replaces the original plastic slider with the adjusting screw 3, and through the cooperation of the adjusting strut 2 and the adjusting screw 3, converts the friction between the original spring 7 and the plastic slider into the frictional force of the thread, so that the overall strength is improved. In addition, a corresponding rubber ring groove is provided on the middle hole of the outer cover 1, so that the adjusting screw 3 is not easily disengaged while not hindering the rotation of the adjusting screw 3.
[0037] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation. An element defined by the statement "comprising a..." does not exclude the presence of additional identical elements in the process, method, article or device comprising said element.
[0038] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
