New Description: [New Technology Field] This creation is about a covered spring-loaded floor drop head, which is designed to meet the demand for water hole plugging of indoor floor drop heads that are not frequently drained. The use of a separate seat sleeve set in the water hole of the drop head seat as an interface enables the design of a set of alternative spring pressure stop plug sets, utilizing the elastic pressure-stop function of the spring-stop plug. It is easy to call for the control of the cover or the disengagement of the water hole according to the demand, in order to achieve the function of drainage and drainage. [Prior Art] Indoor floors such as wide rooms or living rooms do not always face the need for drainage. However, due to the necessity of drainage when occasionally cleaning the floor, it is usually planned to have a drainage pipe and set at the appropriate location. The water hole is drained, and the sewage generated by the cleaning floor is drained to restore the dry state of the floor. - As mentioned above, the use rate of the water hole is quite low, but it is an indispensable facility. It has its necessity. However, in order to achieve the drainage function, such a water hole will drain. The cover plate is designed with a drainage hole _, so that when the water head is not used for a long time, if it is not blocked, the odor of the drainage pipe will be dispersed indoors, and the pests will also be This will lead to the invasion of the room, forming a major concern for indoor environmental sanitation. In order to solve this kind of problem, some operators have designed the sinking hole as a submersible design. The original floor is buried in the predetermined part of the floor, and the head is lowered. The groove has a concave groove, a water drop hole is arranged at the center of the bottom of the groove, and a intercepting rib is formed in the water drop hole interval, and a check hole is formed in the intercepting rib to provide a plug cover for the 4 M413711 group. The plug cover screw is arranged on the bolt hole to block the water drop hole, so as to prevent odor and pests from invading the room, and at the same time, a cover plate is additionally disposed on the top of the drop head seat, and the cover surface is provided with a majority gap. Hole, but want to use When the drain function is used, the tool can be opened by the tool and then the plug cover can be removed from the water drop hole to restore its normal drainage function. After the arm is drained, the plug cover is only required to seal the water hole. At the same time, the cover plate is covered back to the drop head seat to return to the blocking state of the falling water hole. It can be seen from the above description that the existing floor water drop head is mainly designed to block the water drop hole by using the plug cover screw to be provided in the drop hole of the falling water hole in the water drop hole of the water head seat. Under this structural design, no matter whether it wants to restore the drainage function or the tight state of the floor drop head, it needs to be achieved by the screwing and unlocking operation of the plug cover, and the whole action is quite numb and time consuming, which causes it to be invisible. It is necessary to try to solve the improvement by the great inconvenience in use. [New content] There are 4 problems and lacks in the knowledge of the floor sinking. The creator has made special research and improvement, based on his years of experience and technology in related industries, and developed a covered elastic floor. The head, that is, its main purpose is to design through the structure, so that when the plug cover is blocked or detached from the water hole of the falling head seat, it can be achieved by a simpler pressure control method to give better utility. Convenience. The other purpose of this creation is to design the structure through the structure, so that it can use the sleeve of the alternative seat as the assembly interface, and it is easy to obtain the combination of the drop head seat and the spring-loaded water stop plug, giving it a simple group. Convenience. 5 M413711 In order to achieve the goal of the previous design, the design was designed with an alternative seat cover set in the water hole of the drop head seat to enable a set of alternative spring pressure stop plugs. In the design, the set of spring pressure water stop plugs are: a base body with a through hole, a pressure piece set inside the base shaft tube, a lifting member and a spring, and a plug cover locked to the pressure fixing member. The composition, using the elastic pressure opening and closing operation function of the elastic pressure stop plug, so that it can be easily controlled according to the demand - the cover cover or the disengagement relationship of the water drop hole to achieve the function of stopping and draining
