Description

Technical Field

[0001] This utility model relates to the field of safety switch technology, and in particular to an integrated structure of a safety switch transmission mechanism. Background Technology

[0002] A safety switch is essentially a control device designed for certain equipment to ensure that the equipment always operates below (or equal to) its rated value or within its safe operating range. Taking a safety door switch as an example: A safety door switch consists of two interconnected parts: the switch body and the switch's operating mechanism. The switch body typically comprises a solenoid valve connected to a separate power source and a key that controls the solenoid valve's mechanical movement. The switch's operating mechanism, or core mechanism, directly controls whether the load is energized. The moving iron core of the solenoid valve is linked to the mechanical part of the operating mechanism, thereby controlling the connection of the electrical circuit.

[0003] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The diagram shows a safety switch with an existing structure, comprising a housing and a core component housed within the housing. The housing includes a front mounting shell 1 and a rear assembly shell 2. The core component includes a transmission element 3 installed inside the mounting shell. The distal end of the transmission element extends through a through hole at the end of the mounting shell and then through a mating hole in the assembly shell, extending into the assembly shell. In this structure, the mounting shell and the assembly shell are two independently designed components. The assembly shell consists of an independently designed assembly shell cover 4 and an assembly shell 5, which are then connected to the rear end of the mounting shell using connecting screws 6. The transmission element is assembled from an independently designed front section 7 and a rear section 8. The connection between the two is not stable or reliable, and the rear section of the transmission element has rearward-extending limiting supports on both sides, further complicating the design. The existing structure has a complex housing and transmission element design with poor integration; it also makes processing and assembly difficult, increasing manufacturing costs.

[0004] Therefore, how to design an integrated structure for a safety switch transmission mechanism that is simpler and more reasonable in design, easier to process and manufacture, and reduces manufacturing costs has become a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of the above-mentioned defects of the prior art, the technical problem to be solved by this utility model is how to design an integrated structure of a safety switch transmission mechanism that is simpler and more reasonable in structure design, easier to process and manufacture, and can reduce manufacturing costs.

[0006] To achieve the above objectives, this utility model provides an integrated structure for a safety switch transmission mechanism, including a housing and a core structure installed inside the housing; the housing includes a mounting shell with an overall rectangular box structure at the front end and an assembly shell with an overall rectangular box structure at the rear end; the core structure includes a transmission component disposed inside the mounting shell, with one end of the transmission component passing through a through hole at the end of the mounting shell and then passing through a mating hole in the assembly shell and extending into the assembly shell; the assembly shell includes an assembly shell with an overall rectangular box structure at the rear end and an open front end; characterized in that; the assembly shell also includes an assembly shell cover integrally formed and disposed at the rear end of the mounting shell with an overall rectangular box structure and an open rear side, such that the open end of the assembly shell cover is connected to the open end of the assembly shell.

[0012] As an optimization, the mounting shell includes a mounting shell with an overall rectangular box structure at the lower end and an open upper side, and a mounting shell cover is detachably installed at the open end of the mounting shell.

[0013] This makes the design of the mounting case simpler and more reasonable.

[0014] As an optimization, a sealing ring is provided between the mounting housing and the mounting cover.

[0015] In this way, by setting a sealing ring, the mounting housing and the mounting cover can be sealed.

Each of the two front sides of the mounting housing cover is provided with a mating block extending downward towards the front side, and a hinge protrusion is provided on the inner side of each mating block and is rotatably mated in the hinge groove. Furthermore, a fixing hole is provided at the front end of the mounting housing cover and a fastening screw is arranged thereon, so that the fastening screw can be threaded into the threaded mating hole of the mounting housing.

[0017] This design makes the connection between the mounting housing and the mounting cover simpler and more reliable, and also facilitates easy assembly and disassembly.

[0018] As an optimization, the transmission component includes a horizontally arranged front section with a cylindrical structure, a vertically upward-arranged middle section connected to the rear end of the front section, and a horizontally rearward-arranged rear section connected to the upper end of the middle section. The front section, middle section, and rear section are integrally formed.

[0019] In this way, the transmission components are designed as a single piece, which has better integrity compared to the original structure. It eliminates the need for the limiting supports on both sides, making the structural design simpler and easier to process and manufacture. Furthermore, it can save assembly steps, thereby reducing assembly costs.

[0020] As an optimization, a sealing groove is provided in the middle of the front section of the transmission component, and a sealing rubber ring is provided in the sealing groove.

[0021] In this way, by setting a sealing groove on the front section of the transmission component, the position of the sealing ring on the front section of the transmission component can be better restricted, and the sealing effect can also be improved.

[0022] As an optimization, the rear end face of the transmission component is designed with a spherical structure.

[0023] This design is simpler and more reasonable, and can better work in conjunction with the core structure inside the assembly housing.

[0024] As an optimization, an operating support plate is connected to the upper surface of the assembly housing. The upper end of the operating support plate has two mounting holes in a pair. The lower middle part of the operating support plate protrudes downward to form a plug-in plate and is inserted into the assembly housing through the plug-in hole on the upper surface of the assembly housing. The plug-in plate is provided with a clearance opening and a clearance notch.

[0026] In summary, the above-mentioned structure has the advantages of simpler and more reasonable structural design, easier processing and manufacturing, and reduced manufacturing costs. Attached Figure Description
