Description

Technical Field

[0001] The utility model relates to the field of ship seat installation, in particular to a ship seat installation base with a thread lock and a ship seat. Background Art

[0002] Generally speaking, a marine seat is composed of the following components: a seat body 100, a column 200 and a mounting base 300, such as Figure 1 and 2 As shown, the seat body 100 is mounted on the column 200, and the column 200 is inserted and fixed in the mounting base 300. The mounting base 300 is set on the deck, and a cylindrical straight sleeve 4 for mounting the column 200 and a threaded locking nut 5 welded to the bottom of the straight sleeve 4 are arranged inside. When installing the column 200, the column 200 is inserted into the straight sleeve 4 of the mounting base 300, and a threaded structure is arranged at the bottom of the column 200, which is connected with the threaded locking nut 5 by threading, so that the column 200 is fixedly installed in the mounting base 300.

[0003] During the production process of the installation base 300, it is necessary to weld the threaded lock nut 5 to the bottom of the straight sleeve 4. However, during the welding process, since the threaded lock nut 5 is a small part, it is often easy to weld it off-center on the straight sleeve 4, causing the threaded lock nut 5 to be eccentric with the straight sleeve 4. In this case, after the column 200 is inserted into the straight sleeve 4, the bottom external thread cannot be aligned and screwed with the threaded lock nut 5 at the bottom of the straight sleeve 4, making it impossible to install the seat column 200. Utility Model Content

[0004] In view of the defects in the prior art, the purpose of the utility model is to provide a marine seat mounting base and a marine seat with a built-in thread lock to solve the technical problem in the prior art that the thread lock nut is easily welded off-center on the straight sleeve, thereby causing the marine seat to fail to be installed on the deck.

[0041] First Embodiment

[0042] like Figure 4As shown, this embodiment provides a marine seat mounting base with a threaded lock, which is used to lock the column 200 for mounting the marine seat. The bottom end of the column 200 is provided with a second threaded portion 201, which is connected to the marine seat base with a threaded lock provided by this embodiment through threaded matching. The marine seat mounting base with a threaded lock comprises a mounting base 301 and a column mounting locking structure, wherein the column mounting locking structure is a hollow sleeve 302, the mounting base 301 is fixedly arranged on the deck, and a mounting hole is arranged at the center thereof, the hollow sleeve 302 is fixedly connected to the mounting base 301, and the hollow sleeve 302 extends axially in the mounting hole of the mounting base 301 for inserting the column 200. Different from the prior art, the inner side wall of the hollow sleeve 302 is integrally provided with a first threaded portion 305, and the first threaded portion 305 cooperates with the second threaded portion 201 arranged at the bottom of the column 300 so that the column 200 is locked and installed in the hollow sleeve 302. like Figure 4 , 5 As shown, the hollow sleeve 302 as a whole can be a cylindrical hollow straight sleeve with an inward-retracted bottom, having two upper and lower open ends, the first threaded portion 305 is located at the lower open end of the hollow straight sleeve, and the column 200 is inserted into the hollow sleeve 302 through the upper open end. The bottom of the hollow sleeve 302 is inward-retracted, that is, the diameter of its upper open end is larger than the diameter of its lower open end, and the diameter of the first threaded portion 305 at the lower open end matches the diameter of the second threaded portion 201 of the column 200. In addition, a hollow inner sleeve 306 is also provided in the hollow sleeve 302, and the column 200 is inserted into the inner sleeve 306 so that the column is tightly fitted in the hollow sleeve 302. An outer ring opening is also provided around the upper opening of the inner sleeve 306 . When the inner sleeve 306 is inserted into the hollow sleeve 302 , the outer ring opening at the top of the inner sleeve 306 is clamped on the mounting base plate 301 to fix it in the hollow sleeve 302 .

[0043] Different from the prior art, the column mounting locking structure in the marine seat mounting base with a threaded lock provided in this embodiment is a hollow sleeve 302 with a threaded structure, while the column mounting locking structure in the marine seat mounting base in the prior art, such as Figures 1 to 3As shown, it often includes two parts, a straight sleeve 4 and a threaded lock nut 5. The threaded lock nut 5 includes an internal thread. The threaded lock nut 5 is fixedly connected to the bottom of the straight sleeve 4 by welding. The straight sleeve 4 is used to accommodate the column 200, and the threaded lock nut 5 is used to cooperate with the second threaded portion 201 at the bottom of the column 200 to lock it. However, during the welding process of the threaded lock nut 5, it is often easy to have a welding deviation, that is, the welded threaded lock nut 5 and the straight sleeve 4 are not coaxial, resulting in that when the column 200 is inserted into the straight sleeve 4, the column external thread 201 at the bottom cannot be aligned and screwed with the threaded lock nut 5; at the same time, since the threaded lock nut 5 and the straight sleeve 4 are two separate parts, there is also a risk that the threaded lock nut 5 will fall off due to poor welding during the welding process. The bottom opening of the hollow sleeve 302 in the marine seat mounting base with a threaded lock provided in this embodiment is retracted, and the retracted portion of the hollow sleeve 302 at the lower opening end is provided with a first threaded portion 305, which can not only realize the same locking connection between the column 200 and the hollow sleeve 302 after being inserted into the hollow sleeve 302. At the same time, since the first threaded portion 305 at the bottom is integrally formed with the hollow sleeve 302, the first threaded portion 305 and the hollow sleeve 302 are of course concentric and coaxial, so there is no risk of welding deviation of the threaded lock cap 5 during welding and falling off after welding in the prior art, and at the same time, the number of component parts of the marine seat mounting base is reduced, and the production cost is reduced.

[0044] At the same time Figure 4 , Figure 5 As shown, a reinforcing ring 303 is arranged on the outer wall of the hollow sleeve 302, and the top of the reinforcing ring 303 is connected to the mounting base plate 301, so that the connection between the hollow sleeve 302 and the mounting base plate 301 is more stable, and the overall displacement of the hollow sleeve 302 in the horizontal direction is prevented.
