Description

Technical Field

[0001] The utility model relates to a hinge screw for a toilet seat with an integrated installation tool. Background Art

[0002] At present, on the market, toilet seat hinges, ceramics, plastics, etc. need to be fastened with screws, and usually expansion rubber columns, etc. are used for fastening. In addition to the key structural features of the rubber column itself, the way of tightening the screw and the magnitude of the tightening operation force are also very key factors; in addition, the ease of the screwing operation, how much force to use for screwing, and whether there is a loosening prevention structure designed are also very key parameters. In addition, within the torque range that the screw and the hinge can withstand, the greater the tightening force, the less likely it is to loosen subsequently.

[0003] However, the existing screw structures have the following disadvantages:

[0004] 1. Tools are required to tighten. In the case of lack of tools, it is difficult to achieve quick installation and maintenance. The tightening method is relatively single and the operation is inconvenient.

[0005] 2. The locking torque is small. It is difficult to achieve large torque locking with a screwdriver tool, and it is inconvenient to use.

[0006] Therefore, the present utility model is studied and proposed in view of the above problems. Summary of the Utility Model

[0007] The purpose of the present utility model is to overcome the deficiencies of the prior art and provide a hinge screw for a toilet seat with an integrated installation tool. The operator can choose to act on the operation base or the operation rod to act on the connecting screw to screw it into the connecting sleeve column, or can also choose to act on the connecting screw to screw it into the connecting sleeve column by operating an external tool. It has multiple tightening methods, is easy to operate, and has high practicability.

[0008] The present utility model is realized by the following technical solutions:

[0009] A hinge screw for a toilet seat with an integrated installation tool, comprising an operation base 1 and a connecting screw 2 for threadedly connecting with a connecting sleeve column 3 and capable of moving relative to the operation base 1. A base through hole 11 for the connecting screw 2 to pass through is provided on the operation base 1. A synchronous movement mechanism 4 is provided between the operation base 1 and the connecting screw 2, which can act on the connecting screw 2 to quickly screw into the connecting sleeve column 3 and lock when the operation base 1 moves relative to the connecting sleeve column 3; an operation rod 5 for the operator to use to drive the connecting screw 2 to screw into the connecting sleeve column 3 is provided on the connecting screw 2 when the synchronous movement state between the operation base 1 and the connecting screw 2 is released by the synchronous movement mechanism 4.

[0010] As described above, in a seat screw with a self-installing tool, the operating rod 5 is configured so that after the operator operates the base 1 and the synchronous mechanism 4 to screw the connecting screw 2 into the connecting sleeve 3, the operator can continue to screw the connecting screw 2 into the connecting sleeve 3 through the operating rod 5 to lock it.

[0011] As described above, in a self-installing tool-mounted seat screw, the synchronous mechanism 4 includes a synchronous locking position 41 arranged on the operating base 1 or the connecting screw 2 and a synchronous locking member 42 which is movably arranged on the connecting screw 2 or the operating base 1 and can be locked with the synchronous locking position 41.

[0012] As described above, in a self-installing tool-mounted hinge screw, the synchronous locking position 41 is an elastic synchronous buckle arranged on the operating base 1, and the synchronous locking member 42 is a synchronous clamping rod slidably arranged on the connecting screw 2 and engaged with the synchronous buckle.

[0013] As described above, in the self-installing tool-mounted seat screw, a limiting structure 6 is provided between the operating base 1 and the connecting screw 2 for preventing the connecting screw 2 from separating from the operating base 1 when the connecting screw 2 passes through the base through hole 11.

[0014] As described above, in the self-installing tool-mounted seat screw, the limiting structure 6 includes a limiting undercut 61 provided on the operating base 1 and a limiting convex ring 62 provided on the connecting screw 2 and cooperating with the limiting undercut 61 for limiting purpose.

[0015] As described above, for a seat screw with a self-installing tool, a base rubber pad 12 is provided at the bottom of the operating base 1.

[0016] As described above, the self-installing tool seat screw, the operating rod 5 is configured to slide along the radial direction of the connecting screw 2 to form a labor-saving rod.

[0017] As described above, in a seat hinge screw with a self-installing tool, a connecting protrusion 21 is eccentrically provided at the upper end of the connecting screw 2, and a connecting through hole 22 is provided on the connecting protrusion 21; the operating rod 5 includes an operating sliding section 51 slidably and rotatably penetrated through the connecting through hole 22 and an operating rod section 52 connected to one end of the operating sliding section 51, and the other end of the operating sliding section 51 is provided with a blocking protrusion 53 that can cooperate with the corresponding edge of the connecting through hole 22.

[0018] As described above, in the self-installing tool-equipped seat screw, the operating sliding section 51 is vertically connected to the connecting screw 2 , and the operating rod section 52 is arranged in parallel with the connecting screw 2 .

[0020] Compared with the prior art, the utility model has the following advantages:

[0021] 1. When the utility model is installed, the operator first screws the connecting screw into the connecting sleeve column through the operating base by a quick-action connection. When it is impossible to continue screwing the connecting screw into the connecting sleeve column through the operating base, the connecting screw is then screwed into the connecting sleeve column by the action of the operating rod. Therefore, the utility model first quickly screws the connecting screw into the preset position of the connecting sleeve column through the operating base, and then the connecting screw is screwed into the connecting sleeve column by the action of the operating rod. This structural method can ensure that the connection between the connecting screw and the connecting sleeve column is firm and reliable, and at the same time, the operation is convenient.

[0022] 2. The utility model can use external tools to act on the connecting screw to screw it into the connecting sleeve column according to the installation requirements, or directly act on the operating base and the operating rod, with multiple tightening methods and high practicability.

[0023] 3. A base rubber pad is provided at the bottom of the operating base, which can avoid the rigid contact between the operating base and the external installation part. At the same time, the elasticity generated by the base rubber pad combined with the secondary strengthening and locking of the operating rod can achieve no loosening after long-term use, reliable structural connection, long service life, and good resistance to vibration and impact.

[0024] 4. In order to achieve large-torque locking and convenient operation, the operating rod is configured to be slidable along the radial direction of the connecting screw to form a labor-saving rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0034] As Figure 1-7 shown, a hinge screw with a built-in installation tool seat of the present utility model includes an operation base 1 and a connection screw 2 that is threadedly connected to a connection sleeve column 3 and can move relative to the operation base 1. A base through hole 11 for the connection screw 2 to pass through is provided on the operation base 1. A synchronous movement mechanism 4 is provided between the operation base 1 and the connection screw 2, which can act on the connection screw 2 to quickly screw into the connection sleeve column 3 and lock when the operation base 1 moves relative to the connection sleeve column 3. An operation rod 5 is provided on the connection screw 2, which is used for the operator to use to drive the connection screw 2 to screw into the connection sleeve column 3 when the synchronous movement state between the operation base 1 and the connection screw 2 is released by the synchronous movement mechanism 4. When installing the present utility model, the operator first quickly screws the connection screw into the connection sleeve column through the operation base. When the connection screw cannot be screwed into the connection sleeve column continuously through the operation base, the connection screw is then screwed into the connection sleeve column continuously through the action of the operation rod. Therefore, through the structural method of first quickly screwing the connection screw into the preset position of the connection sleeve column through the operation base and then screwing the connection screw into the connection sleeve column continuously through the action of the operation rod, the present utility model can ensure that the connection between the connection screw and the connection sleeve column is firm and reliable, and at the same time, the operation is convenient and the operation methods are diversified.

[0035] As Figure 1 、 2 、4, and 5 shown, a slot for a screwdriver is reserved at the upper end of the connection screw 2 to ensure traditional locking methods, so that the operator can also use external tools such as a screwdriver to tighten, and it is also beneficial to the electric locking during the installation process.

[0036] The present utility model has the advantages of a compact structure, strong locking ability, and taking into account the advantages of the old screwdriver locking method.

[0037] As Figure 3 、 4 shown, a reinforcing gasket is provided between the operation base 1 and the upper end of the connection screw 2. Among them, a receiving cavity that is communicated with the base through hole 11 and is used for receiving the upper end of the connection screw 3 is provided on the operation base 1.

[0038] In order to lock more firmly, the operation rod 5 is configured such that after the operator screws the connection screw 2 into the connection sleeve column 3 through the operation base 1 and the synchronous movement mechanism 4, the operator can continue to screw the connection screw 2 into the connection sleeve column 3 through the action of the operation rod 5 to lock.

[0039] In order to ensure stable synchronous cooperation between the operating base 1 and the connecting screw 2, the synchronous mechanism 4 includes a synchronous locking position 41 provided on the operating base 1 or the connecting screw 2 and a synchronous locking member 42 movably provided on the connecting screw 2 or the operating base 1 and capable of locking with the synchronous locking position 41. In this embodiment, the synchronous locking member 42 is composed of the operating rod 5, which simplifies the structure, is reasonably designed, and reduces the manufacturing cost.

[0040] In order to ensure stable engagement between the synchronously moving card rod and the synchronously moving buckle, the synchronously moving locking position 41 is an elastic synchronously moving buckle provided on the operating base 1, and the synchronously moving locking member 42 is a synchronously moving card rod slidably provided on the connecting screw 2 and engaged with the synchronously moving buckle.

[0041] In order to prevent the connection screw from being separated from the operating base to ensure subsequent normal use, a limiting structure 6 is provided between the operating base 1 and the connection screw 2 to prevent the connection screw 2 from being separated from the operating base 1 when the connection screw 2 is inserted into the base through hole 11. The limiting structure 6 includes a limiting undercut 61 provided on the operating base 1 and a limiting convex ring 62 provided on the connection screw 2 and limitedly matched with the limiting undercut 61.

[0042] In order to facilitate smooth assembly, the limiting undercut 61 and the limiting convex ring 62 are provided with guiding inclined surfaces.

[0043] The bottom of the operating base 1 is provided with a base rubber pad 12 to avoid rigid contact between the operating base and the external mounting portion. At the same time, the elasticity generated by the base rubber pad combined with the secondary reinforced locking of the operating rod can ensure that it will not loosen during long-term use, has a reliable structural connection, a long service life, and good resistance to vibration and impact.

[0044] like Figure 3 , 4 As shown, a positioning mechanism is provided between the base rubber pad 12 and the operating base 1, and the positioning structure includes a positioning hole provided on the bottom of the operating base 1 and a positioning protrusion provided on the base rubber pad 12 and insertable into the positioning hole for positioning. The positioning protrusion and the positioning hole are positioned to ensure that the base rubber pad 12 is accurately fitted to the bottom of the operating base 1 to avoid misalignment and offset. In this embodiment, the positioning protrusion and the positioning hole are positioned to ensure that the base rubber pad 12 is connected to the operating base 1 in a synchronous manner.

[0045] In order to achieve high torque locking and convenient operation, the operating rod 5 is configured to slide along the radial direction of the connecting screw 2 to form a labor-saving rod.

[0046] In order to facilitate the operation of locking, a connecting lug 21 is eccentrically provided at the upper end of the connecting screw 2, and a connecting through hole 22 is provided on the connecting lug 21; the operating rod member 5 includes an operating sliding section 51 slidably and rotatably passing through the connecting through hole 22 and an operating rod section 52 connected to one end of the operating sliding section 51, and a blocking lug 53 capable of blocking and cooperating with the corresponding edge of the connecting through hole 22 is provided at the other end of the operating sliding section 51. Among them, as Figure 6 , 7 shown, a dust cover is further included, and the operating sliding section 51 is slidably and rotatably passed through the connecting through hole 22, which facilitates rotating the operating sliding section 51 to make the operating rod section 52 parallel to the upper end face of the connecting screw 2, so as to facilitate the dust cover to cover and store the operating rod member 5.

[0047] In order to facilitate the operation of locking, the operating sliding section 51 is vertically connected to the connecting screw 2, and the operating rod section 52 is arranged parallel to the connecting screw 2.

[0048] In order to make the connection and locking more firm, a connective sleeve column 3 capable of elastic deformation is further included.
