Description

Technical Field

[0001] The utility model relates to a common toilet cover quick pivoting structure. Background Art

[0002] An ordinary toilet cover is composed of an upper cover and a seat ring through a hinge shaft. For example, a Chinese utility model patent (CN201213769Y) discloses a slow-drop toilet cover installation structure, in which the seat 1 and the cover 2 are pivotally connected, and a connecting shaft 5 and a slow-drop rotating shaft 4 are coaxially inserted into the seat sleeve 1.1 and the mounting hole 3 of the cover sleeve. The connecting shaft 5 has an annular groove 5.1 in the radial direction, and the seat sleeve 1.1 has a bayonet 1.2 that communicates with the mounting hole 3 at the position of the annular groove 5.1. The lock 6 is buckled into the bayonet 1.2 and the annular groove 5.1, so that the connecting shaft 5 cannot move axially, so that the connecting shaft 5 and the slow-drop rotating shaft 4 can be pivotally connected and fixed in the seat sleeve mounting hole 3 of the cover 2. The problems existing in the pivot connection structure of this toilet cover are:

[0003] 1. For public health places in some populous developing countries, due to the large population mobility, high frequency of use, and short time of using the toilet, the use of the slow-falling shaft 4 also increases the manufacturing and sales cost of the entire toilet cover. Therefore, for some economically backward developing countries, the slow-falling shaft 4 of the toilet cover is not necessary.

[0004] 2. Since the seat ring sleeve 1.1 is provided with a bayonet 1.2, the connecting shaft 5 is provided with an annular groove 5.1, and a lock 6 needs to be added, the mold development cost of this toilet is increased, the product has many parts and components, and the structure is complex, resulting in higher assembly and production costs than ordinary toilet covers. In addition, the lock 6 and the bayonet 1.2 cooperate to form a gap on the surface of the sleeve 1.1 that is easy to hide dirt and grime, affecting the hygienic use of the seat plate 1. Utility Model Content

[0005] The utility model provides a common toilet cover quick pivoting structure, which can effectively solve the above problems.

[0006] The utility model is achieved in this way:

[0007] A common toilet cover quick pivot structure, comprising a seat ring sleeve and an upper cover sleeve; further comprising a pivot sleeve that coaxially connects the seat ring sleeve and the upper cover sleeve together so as to allow the upper cover and the seat ring to pivot and rotate; the pivot sleeve is composed of an integrally formed convex ring portion and a tube portion, the tube portion has at least one boss on its circumference, and a limiting groove for the boss to be engaged is provided on the outer side of the seat ring sleeve;

[0008] When the pivot sleeve is inserted into the aligned seat ring sleeve and upper cover sleeve from the inside, the convex ring portion of the pivot sleeve contacts and presses against the inner surface of the pivot hole of the seat ring sleeve, and the boss on the tube portion is engaged in the limiting groove to axially lock the pivot sleeve between the seat ring sleeve and the upper cover sleeve.

[0009] As a further improvement, the limiting groove is in the shape of an annular step extending from the outside of the seat ring sleeve to the inside; when the seat ring sleeve rotates around the pivot sleeve, the limiting groove can avoid the boss.

[0010] As a further improvement, the number of bosses on the circumferential side of the pivot sleeve portion is two and they are symmetrically arranged on both sides of the tube portion.

[0011] As a further improvement, at least two symmetrically arranged air-avoiding slits are provided through the circumferential side of the tube portion and extend from the end of the tube portion toward the boss; when the tube portion slides into the pivot hole of the seat ring sleeve, the boss is subjected to pressure from the wall of the pivot hole, causing the tube portion to undergo radial elastic bending inward with the air-avoiding slit as the central axis; when the boss on the tube portion moves to the limiting groove, the tube portion is deformed and restored, and the boss is snapped into the limiting groove.

[0012] As a further improvement, an axial hole penetrating the convex ring portion and the tube portion is provided on the pivot sleeve, and the axial hole can be used for the transverse axis section on the ceramic toilet support to be inserted and installed.

[0013] As a further improvement, the end surface of the convex ring portion is provided with a guide surface which is connected with the shaft hole and is in a flared shape.

[0014] The beneficial effects of the utility model are:

[0015] The utility model does not use a slow-drop rotating shaft, uses fewer parts, has a simple and reliable structure and function, and has a low manufacturing cost. The upper cover sleeve and the seat ring sleeve are quickly connected in series to prevent falling off using a pivot sleeve, and it is very convenient to pivot the upper cover and the seat ring together for assembly. The surfaces of the upper cover sleeve and the seat ring sleeve are smooth and have no gaps that may cause dirt, so that the toilet cover plate as a whole is both beautiful and easy to clean, and is very suitable for use in public health places in developing countries with relatively backward economic development.

[0024] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0025] like Figure 1 to Figure 6 As shown, a common toilet cover quick pivot structure includes a seat ring sleeve 21 and an upper cover sleeve 11; it also includes a pivot sleeve 30 that coaxially connects the seat ring sleeve 21 and the upper cover sleeve 11 together so that the upper cover 10 and the seat ring 20 can be pivoted and rotated. The pivot sleeve 30 is composed of an integrally formed convex ring portion 31 and a tube portion 32. The tube portion 32 has at least one boss 321 on its circumference, and a limiting groove 212 for the boss 321 to engage is provided on the outer side of the seat ring sleeve 21; when the pivot sleeve 30 is inserted from the inside into the aligned seat ring sleeve 21 and the upper cover sleeve 11, the convex ring portion 31 of the pivot sleeve 30 contacts and presses against the inner edge of the pivot hole 211 of the seat ring sleeve 21, and the boss 321 on the tube portion 32 engages in the limiting groove 212, so as to axially lock the pivot sleeve 30 between the seat ring sleeve 21 and the upper cover sleeve 11. The utility model only uses a pivot sleeve 30 to quickly connect the upper cover sleeve 11 and the seat ring sleeve 21 together. The assembled upper cover sleeve and the seat ring sleeve have smooth surfaces and no gaps for dirt, which not only improves the overall aesthetics of the cover plate, but also facilitates subsequent cleaning.

[0026] The structures of the various components of the utility model are described below.

[0027] like Figure 2 to Figure 5As shown, in this embodiment, there are two bosses 321 on the circumferential side of the tube portion 32 of the pivot sleeve 30 and they are symmetrically arranged on both sides of the tube portion 32. The limiting groove 212 is in the shape of an annular step from the outside to the inside of the seat ring sleeve 21. When the seat ring sleeve 21 rotates around the pivot sleeve 30, the limiting groove 212 can make way for the boss 321 to avoid space, so that the seat ring 20 can rotate smoothly.

[0028] like Figure 2 to Figure 5 As shown, at least two symmetrically arranged air-avoiding slits 322 are provided on the circumference of the tube portion 32 and extend from the end of the tube portion 32 toward the boss 321; when the tube portion 32 slides into the pivot hole 211 of the seat ring sleeve 21, the boss 321 thereon is subjected to the pressure of the wall of the pivot hole 211, causing the tube portion 32 to undergo radial elastic bending inward with the air-avoiding slit 322 as the central axis; when the boss 321 on the tube portion 32 moves to the limiting groove 212, the tube portion 32 is deformed and reset, and the boss 321 is snapped into the limiting groove 212, thereby realizing the axial locking installation of the pivot sleeve 30.

[0029] like Figure 2 and Figures 4 to 6 As shown, the pivot sleeve 30 is provided with an axial hole 301 which passes through the convex ring portion 31 and the tube portion 32. The axial hole 301 can be used for the transverse axis section 41 on the ceramic toilet support 40 to be inserted and installed; the end face of the convex ring portion 31 is provided with a guide surface 302 which is connected with the axial hole 301 and is in a flared shape. Such a design makes it convenient for the transverse axis section 41 to be centrally inserted into the axial hole 301 by touching and sliding the guide surface 302.

[0030] Combine the following Figure 1 to Figure 6 The working principle of the utility model is described in detail, and the utility model is used to realize the rapid serial connection and anti-detachment of the upper cover 10 and the seat ring 20.

[0031] During installation, the pivot sleeve 30 is inserted into the seat ring sleeve 21 and the upper cover sleeve 11 which are aligned and placed in sequence, and the boss 321 on the tube portion 32 slides into the pivot hole 211 of the seat ring sleeve 21, and the tube portion 32 extending into the upper cover sleeve 11 is elastically bent inward until the boss 321 is engaged with the limiting groove 212. At this time, the convex ring portion 31 of the pivot sleeve 30 forms a contact pressure with the inner edge surface of the pivot hole 211, thereby completing the rapid serial installation of the upper cover 10 and the seat ring 20.

[0032] The above embodiments are only used to illustrate the present invention, not to limit the present invention. A person skilled in the art may make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also fall within the scope of the present invention and be defined by the claims.
