Description

Technical Field

[0001] This invention relates to a hinge screw with a built-in mounting tool holder. Background Technology

[0002] Currently, toilet seats on the market, whether ceramic or plastic, require screws for fastening, typically using expansion joints. The effectiveness of this fastening depends not only on the structural characteristics of the expansion joint itself, but also on the method of tightening the screw and the amount of force applied. Furthermore, the ease of tightening, the amount of force used, and the presence of anti-loosening mechanisms are also crucial parameters. Additionally, within the torque range that the screw and seat hinge can withstand, a greater tightening force reduces the likelihood of future loosening.

[0003] However, the old screw structure has the following disadvantages: 1. Tools are required to tighten it. In the absence of tools, it is difficult to achieve quick installation and maintenance. The tightening method is relatively simple and inconvenient to operate.

[0004] 2. The tightening torque is relatively small, making it difficult to achieve a large tightening torque using a screwdriver, which is inconvenient to use.

[0005] Therefore, this invention addresses the aforementioned problems. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a screw with a built-in installation tool base. The operator can choose to use the operating base or operating rod to screw the connecting screw into the connecting sleeve, or choose to use an external tool to screw the connecting screw into the connecting sleeve. It has multiple tightening methods, is easy to operate, and is highly practical.

[0007] This invention is achieved through the following technical solution: A self-mounting tool holder screw includes an operating base 1 and a connecting screw 2 for threaded connection with a connecting sleeve 3 and movable relative to the operating base 1. The operating base 1 is provided with a base through hole 11 for the connecting screw 2 to pass through. A co-movement mechanism 4 is provided between the operating base 1 and the connecting screw 2, which can cause the connecting screw 2 to be quickly screwed into the connecting sleeve 3 and locked when the operating base 1 is movable relative to the connecting sleeve 3. The connecting screw 2 is provided with an operating rod 5, which can be used by the operator to drive the connecting screw 2 into the connecting sleeve 3 when the co-movement mechanism 4 is released from the co-movement state between the operating base 1 and the connecting screw 2.

[0008] As described above, in a hinge screw with a built-in installation tool seat, the operating lever 5 is configured such that after the operator screws the connecting screw 2 into the connecting sleeve 3 by operating the base 1 and the synchronous mechanism 4, the operator can continue to screw the connecting screw 2 into the connecting sleeve 3 by operating the operating lever 5 to lock it in place.

[0009] As described above, a self-mounting tool seat hinge screw, wherein 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 and engaging with the synchronous locking position 41.

[0010] As described above, in a hinge screw with a built-in installation tool seat, the synchronous locking position 41 is an elastic synchronous buckle provided on the operating base 1, and the synchronous locking member 42 is a synchronous locking rod that is slidably provided on the connecting screw 2 and engages with the synchronous buckle.

[0011] As described above, a self-installing tool seat hinge screw is provided between the operating base 1 and the connecting screw 2, which is a limiting structure 6 used to prevent the connecting screw 2 from separating from the operating base 1 when the connecting screw 2 passes through the through hole 11 of the base.

[0012] As described above, a self-installing tool seat hinge screw, wherein the limiting structure 6 includes a limiting buckle 61 provided on the operating base 1 and a limiting protrusion 62 provided on the connecting screw 2 and engaged with the limiting buckle 61 for limiting.

[0013] As described above, a hinge screw with a built-in installation tool seat has a base rubber pad 12 at the bottom of the operating base 1.

[0014] As described above, in a type of hinge screw with a built-in mounting tool holder, the operating lever 5 is configured to slide radially along the connecting screw 2 to form a force-saving lever. As described above, a self-mounting tool seat hinge screw has a connecting protrusion 21 eccentrically provided on the upper end of the connecting screw 2, and a connecting through hole 22 provided on the connecting protrusion 21; the operating rod 5 includes an operating sliding section 51 that can slide and rotatably pass 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 protrusion 53 that can cooperate with the corresponding edge blocking of the connecting through hole 22 at the other end of the operating sliding section 51.

[0015] As described above, in a hinge screw with a built-in installation tool seat, the operating sliding section 51 is perpendicularly connected to the connecting screw 2, and the operating lever section 52 is arranged parallel to the connecting screw 2.

[0016] As described above, a hinge screw with a built-in installation tool seat also includes a flexible connecting sleeve 3.

[0017] Compared with the prior art, the present invention has the following advantages: 1. During installation, the operator first uses the operating base to quickly screw the connecting screw into the connecting sleeve. When the operating base can no longer screw the connecting screw into the connecting sleeve, the operating lever is then used to continue screwing the connecting screw into the connecting sleeve. Therefore, the structure of the present invention, which first uses the operating base to quickly screw the connecting screw into the preset position of the connecting sleeve, and then uses the operating lever to continue screwing the connecting screw into the connecting sleeve, can ensure a firm and reliable connection between the connecting screw and the connecting sleeve, while also being convenient to operate.

[0018] 2. This invention can be used to tighten screws into connecting sleeves using external tools according to installation requirements, or it can be used directly on the operating base and operating rods, providing multiple tightening methods and high practicality.

[0019] 3. The bottom of the operating base is equipped with a base rubber pad, which can prevent the operating base from rigidly contacting the external mounting part. At the same time, the elasticity of the base rubber pad, combined with the secondary reinforcement and locking of the operating rod, can ensure that it will not loosen during long-term use, with reliable structural connection, long service life, and good resistance to vibration and impact.

[0020] 4. In order to achieve high torque locking and convenient operation, the operating lever is configured to slide along the radial direction of the connecting screw to form a force-saving lever. Attached Figure Description

[0028] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0029] like Figure 1-7As shown, the present invention provides a self-mounting tool seat hinge screw, including an operating base 1 and a connecting screw 2 for threaded connection with a connecting sleeve 3 and movable relative to the operating base 1. The operating base 1 is provided with a base through hole 11 for the connecting screw 2 to pass through. A co-movement mechanism 4 is provided between the operating base 1 and the connecting screw 2, which can cause the connecting screw 2 to be quickly screwed into the connecting sleeve 3 and locked when the operating base 1 is movable relative to the connecting sleeve 3. The connecting screw 2 is provided with an operating rod 5, which can be used by the operator to drive the connecting screw 2 into the connecting sleeve 3 when the co-movement mechanism 4 is released from the co-movement state between the operating base 1 and the connecting screw 2. During installation, the operator first uses the operating base to quickly screw the connecting screw into the connecting sleeve. When the operating base can no longer screw the connecting screw into the connecting sleeve, the operating lever is then used to continue screwing the connecting screw into the connecting sleeve. Therefore, the structure of this invention, which first uses the operating base to quickly screw the connecting screw into the preset position of the connecting sleeve, and then uses the operating lever to continue screwing the connecting screw into the connecting sleeve, can ensure a firm and reliable connection between the connecting screw and the connecting sleeve, while also being convenient and versatile in operation.

[0030] like Figure 1 , 2 As shown in Figures 4 and 5, the upper end of the connecting screw 2 retains a slot for a screwdriver to ensure that the traditional locking method can be used by the operator to tighten it with external tools such as a screwdriver. It also facilitates the electric locking during the installation process.

[0031] This invention has the advantages of compact structure, strong locking capability, and the ability to retain the traditional screwdriver locking method.

[0032] like Figure 3 , 4 As shown, a reinforcing washer is provided between the operating base 1 and the upper end of the connecting screw 2. The operating base 1 has a receiving cavity that communicates with the base through hole 11 and is used to accommodate the upper end of the connecting screw 3.

[0033] To ensure a more secure lock, the operating lever 5 is configured such that after the operator screws the connecting screw 2 into the connecting sleeve 3 via the operating base 1 and the synchronous mechanism 4, the operator can continue to screw the connecting screw 2 into the connecting sleeve 3 via the operating lever 5 to lock it in place.

[0034] To ensure stable synchronous engagement between the operating base 1 and the connecting screw 2, the synchronous engagement mechanism 4 includes a synchronous locking position 41 disposed on the operating base 1 or the connecting screw 2, and a synchronous locking member 42 movably disposed on the connecting screw 2 or the operating base 1 and capable of locking into the synchronous locking position 41. In this embodiment, the synchronous locking member 42 is composed of an operating lever 5, which simplifies the structure, is reasonably designed, and reduces manufacturing costs.

[0035] To ensure stable engagement between the synchronous locking lever and the synchronous locking buckle, the synchronous locking position 41 is an elastic synchronous locking buckle provided on the operating base 1, and the synchronous locking member 42 is a synchronous locking lever that is slidably provided on the connecting screw 2 and engages with the synchronous locking buckle.

[0036] To prevent the connecting screw from separating from the operating base and ensure normal subsequent use, a limiting structure 6 is provided between the operating base 1 and the connecting screw 2 to prevent the connecting screw 2 from separating from the operating base 1 when it passes through the through hole 11 of the base. The limiting structure 6 includes a limiting buckle 61 provided on the operating base 1 and a limiting protrusion 62 provided on the connecting screw 2 and engaging with the limiting buckle 61.

[0037] To facilitate smooth and convenient assembly, the limiting buckle 61 and the limiting protrusion 62 are provided with guide slopes.

[0038] The operating base 1 has a base rubber pad 12 at the bottom, which can prevent the operating base from rigidly contacting the external mounting part. At the same time, the elasticity generated by the base rubber pad, combined with the secondary reinforcement and locking of the operating rod, can achieve long-term use without loosening, reliable structural connection, long service life, and good resistance to vibration and impact.

[0039] like Figure 3 , 4 As shown, a positioning mechanism is provided between the base pad 12 and the operating base 1. The positioning mechanism includes a positioning hole on the bottom of the operating base 1 and a positioning protrusion on the base pad 12 that can be inserted into the positioning hole for positioning. This positioning engagement between the positioning protrusion and the positioning hole ensures that the base pad 12 is precisely fitted to the bottom of the operating base 1, preventing misalignment or displacement. In this embodiment, the positioning engagement between the positioning protrusion and the positioning hole also allows the base pad 12 and the operating base 1 to move synchronously.

[0040] To achieve high-torque locking and convenient operation, the operating lever 5 is configured to slide along the radial direction of the connecting screw 2 to form a force-saving lever. For easier locking, the upper end of the connecting screw 2 is eccentrically provided with a connecting protrusion 21, and the connecting protrusion 21 is provided with a connecting through hole 22; the operating rod 5 includes an operating sliding section 51 that is slidably and rotatably inserted 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. Wherein, as Figure 6 , 7 As shown, it also includes a dust cover, and the operating sliding section 51 is slidably and rotatably inserted through the connecting through hole 22, which makes it easy to rotate the operating sliding section 51 so that the operating rod section 52 is parallel to the upper end face of the connecting screw 2, thereby making it easy for the dust cover to cover and store the operating rod 5.

[0041] For better operation and locking, the operating sliding section 51 is perpendicularly connected to the connecting screw 2, and the operating lever section 52 is parallel to the connecting screw 2.

[0042] To ensure a more secure connection and locking, a flexible connecting sleeve 3 is also included.
