A pre-embedded box with adjustable pre-embedding depth

Abstract

The invention discloses an embedded box with an adjustable embedding depth. The embedded box with the adjustable embedding depth comprises a box body and an adjustment ring. The box body comprises a head. The adjustment ring is provided with installation holes. The head is provided with an adjustment external thread. A plurality of clamping ports are formed in each circle of the adjustment external thread. The inner wall of the adjustment ring is provided with an adjustment internal thread matched with the adjustment external thread and a groove used for breaking the adjustment internal thread. An elastic arm is arranged in the groove. Fixing bosses matched with the clamping ports are arranged at the free end of the elastic arm. A sliding groove is formed between the elastic arm and the wall of the groove. A sliding block is installed in the sliding groove. According to the embedded box with the adjustable embedding depth, each circle of the adjustment external thread is provided withthe multiple corresponding clamping ports so that each thread pitch fixing boss can be selectively matched with one of the multiple clamping ports, namely each thread pitch adjustment ring can be selectively fixed in one of multiple positions correspondingly; and under the same distance condition, the embedded box can have more position adjustment points, the embedding depth adjustment precision is higher, and the fine adjustment function can be achieved.

Description

technical field [0001] The invention relates to the technical field of household sanitary products, in particular to a pre-embedded box. Background technique [0002] In order to have a beautiful appearance and save space, the pipes and control valves of existing water equipment such as showers or bathtubs in bathrooms are often buried in the wall in a concealed way, and only the control knobs are exposed on the wall surface to facilitate the waterway. broken control. There is an existing pre-embedded box, which includes a box body and an adjusting ring set on the box body. When pre-embedding, the box body can be fixed to the wall through the adjusting ring. In order to adjust the pre-embedded depth of the pre-embedded box in the wall, the box The outer wall is provided with a number of card slots arranged in the axial direction of the box body, and the adjustment ring is provided with protrusions that cooperate with the card slots. By selecting different card slots and pro...

There is an existing pre-embedded box, which includes a box body and an adjusting ring set on the box body. When pre-embedding, the box body can be fixed to the wall through the adjusting ring. In order to adjust the pre-embedded depth of the pre-embedded box in the wall, the box The outer wall is provided with a number of card slots arranged in the axial direction of the box body, and the adjustment ring is provided with protrusions that cooperate with the card slots. By selecting different card slots and protrusions, the axial direction of the adjustment ring set on the box body can be adjusted. position, so as to achieve the purpose of adjusting the embedded depth of the embedded box; however, because the slots of this embedded box are set along the axial direction, the distance between the slots can only be adjusted each time. However, in order to ensure that the adjustment ring and the box body The connection reliability is high, and the card slot cannot be set too small, and the width is often more than 10mm. Therefore, the adjustment of the embedded depth is not fine enough, and it is difficult to achieve the desired effect in many cases.

Moreover, in order to connect with external water pipes and facilitate the installation of control valves, a valve body seat is installed inside the box body. The valve body seat includes a seat core for installing a control valve, and several pipe interfaces for connecting external water pipes are arranged around the seat core. At the same time, the box body is provided with a water inlet and outlet at the position corresponding to the pipe interface, and the pipe interface is inserted at the water inlet and outlet. There is also a large piece of rubber to fix the seal; however, with this structure, when the water pipe connected to the pipe interface is subjected to external force, because the rubber is soft and easy to deform, it is prone to the problem of poor sealing, so leakage will still occur question
