Force-limiting damping device

Abstract

The invention provides a force-limiting damping device. The force-limiting damping device is provided with a body, a knocking piece, a damping elastic piece and a force limiting set, wherein the bodyis provided with a combining part and a holding part, the knocking piece is movably combined with the body and can move relative to the combining part, the knocking piece is provided with a sleeving part, a knocking part and a locking part, the sleeving part is movably combined with a sleeving hole of the combining part, the knocking part is arranged at one end of the sleeving part and located below the combining part, the locking part is combined with the sleeving part and abuts against the combining part, the damping elastic piece is arranged on the sleeving part in a sleeving mode and abutsagainst the combining part and the knocking part, and the force limiting set is arranged between the knocking piece and the body. Therefore, the force-limiting damping device which has the remindingeffect, has the improved vibration feeling and has the force application range capable of being adjusted according to needs is provided.

Description

technical field [0001] The invention relates to a force-limiting shock-absorbing device, in particular to a force-limiting shock-absorbing device which has a reminder effect, improves vibration experience, and can adjust the range of applied force as required. Background technique [0002] At present, the hammer or iron hammer used to strike the nail body in the wood, cement wall or metal plate in the industry will often bounce due to the reaction force when striking, which will not only shorten the striking surface of the hammer or iron hammer The time of contact with the nail body will easily cause the nail body to bend or deflect, and the reaction force of its immediate rebound will be converted into heat energy and noise loss, which will relatively reduce the effectiveness of the user's force. That is to say, the exerted force cannot be fully used on the nail body, so that the user needs to strike the nail body several times before the nail body can be knocked into and f...

Problems solved by technology

[0002] At present, the hammer or iron hammer used to strike the nail body in the wood, cement wall or metal plate in the industry will often bounce due to the reaction force when striking, which will not only shorten the striking surface of the hammer or iron hammer The time of contact with the nail body will easily cause the nail body to bend or deflect, and the reaction force of its immediate rebound will be converted into heat energy and noise loss, which will relatively reduce the effectiveness of the user's force. That is to say, the exerted force cannot be fully used on the nail body, so that the user needs to strike the nail body several times before the nail body can be knocked into and fixed in the board or wall, which increases relatively. The number of times of knocking and the time required; in addition, when the user holds the handle of a hammer or iron hammer, the bounce vibration generated during the knocking will also make the user feel uncomfortable; moreover, the current existing medical treatment With a hammer or surgical hammer, the percussion surface is mostly a rigid structure. Therefore, when the dentist uses the existing medical hammer or surgical hammer in artificial dental implant surgery, the rebound generated by the reaction force will not only It makes the doctor feel difficult to hold and uncomfortable, and the patient will feel pain because of the percussion force, and even concussion

[0003] In view of this, existing industrial hammers, iron hammers, medical hammers or surgical hammers, etc., the rigid percussion surface will produce an immediate rebound reaction force when used, not only will produce a considerable degree of noise and discomfort, It will also affect the smoothness and controllability of its operation, and it cannot provide a reminder of the strength of the force, and it cannot allow the user to tap within the corresponding force application range. The user feels that it is difficult to hold and uncomfortable, and it will cause the object or object to be subjected to vibration or discomfort, and the existing industrial hammers, hammers, medical hammers or surgical hammers, etc., cannot meet the needs of users. Make adjustments, relatively limit its practicability and flexibility, and there is room for improvement
