Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, specifically to a lifting rod press-start structure. Background Technology

[0002] A noodle cooker is a kitchen appliance used for cooking noodles, dumplings, or blanching food. It is suitable for places with high customer traffic such as noodle shops, restaurants, and canteens. Different types of food need to be cooked separately in different noodle baskets. Therefore, noodle cookers are generally equipped with an automatic lifting system for the noodle baskets. However, in the humid environment of the kitchen with accumulated oil fumes, the start switch of the existing automatic lifting system is prone to water ingress and failure. Moreover, the signal wire of the start switch will be repeatedly folded as the lifting rod moves back and forth. After a period of use, the signal wire is prone to fatigue and breakage. Therefore, the service life of the automatic lifting system is relatively short and has certain limitations. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a lifting rod press-start structure that is simple in structure, small in size, highly reliable and stable, and has a long service life.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A lifting rod press-activated structure includes a lifting rod, an end cover, a micro switch, and an end cap. The end cover has a mounting hole, and the micro switch is disposed in the mounting hole. The end cover is disposed at the upper end of the lifting rod, and the end cap is disposed at the upper end of the lifting rod and covers the end cover. The inner wall of the pressing surface of the end cap is formed with a first protrusion for abutting against the upper surface of the end cover, and a second protrusion is formed on the inner side of the first protrusion for abutting against the micro switch.

[0006] As a further improvement to the above technical solution:

[0007] The lifting rod has a cavity, and the end cap has a plug and an inner extension. The inner extension passes through the cavity, and the plug abuts against the end of the lifting rod.

[0008] The lifting rod is provided with several sets of through holes, and the inner extension of the tube is provided with several sets of positioning holes. Fasteners pass through the through holes and are inserted into the positioning holes so that the end cap is fixedly connected to the lifting rod.

[0009] The inner side wall of the end cap is formed with a limiting protrusion for abutting against the plug, and a deformation chamber is formed on the side of the end cap away from the plug.

[0010] The plug has a recessed cavity, the mounting hole is located in the recessed cavity, the second boss can be deformed by the pressing surface of the end cap and extend into the mounting hole and abut against the micro switch, and the first boss can be deformed by the pressing surface of the end cap and extend into the recessed cavity and abut against the upper end surface of the recessed cavity.

[0011] The mounting hole is provided with a limiting groove, and the micro switch is provided with a limiting protrusion. The limiting protrusion abuts against the limiting groove so that the micro switch is positioned in the mounting hole.

[0012] The end cap is a one-piece molded structure and is made of flexible material.

[0013] The flexible material is silicone.

[0014] Compared with the prior art, the advantages of this utility model are:

[0015] The microswitch of this utility model's lifting rod press-start structure is installed inside the end cover, which is mounted on the lifting rod. An end cap is also mounted on the lifting rod and covers the end cover, effectively preventing water or oil from entering the microswitch and causing malfunction. A first protrusion and a second protrusion are formed on the inner side of the pressing surface of the end cap. When the lifting rod needs to be controlled to move, the user can directly press the pressing surface of the end cap, causing the first and second protrusions to move closer to the end cover. When the second protrusion contacts the microswitch, the microswitch sends an action signal to the drive device, causing the lifting rod to perform the corresponding action. Simultaneously, the first protrusion contacts the upper surface of the end cover, preventing the second protrusion from excessively squeezing the microswitch. Furthermore, the signal wire of the microswitch passes through the mounting hole and extends into the lifting rod, avoiding repeated folding or squeezing of the signal wire, which helps extend the service life of the microswitch. It has the advantages of simple structure, small size, high reliability and stability, and good ease of use. Attached Figure Description

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 5 As shown, the lifting rod press-start structure of this embodiment includes a lifting rod 1, an end cover 2, a micro switch 3, and an end cap 4. The end cover 2 has a mounting hole 201, and the micro switch 3 is disposed in the mounting hole 201. The end cover 2 is disposed at the upper end of the lifting rod 1, and the end cap 4 is disposed at the upper end of the lifting rod 1 and covers the end cover 2. The inner wall of the pressing surface of the end cap 4 is formed with a first boss 401 for contacting the upper surface of the end cover 2, and the inner side of the first boss 401 is formed with a second boss 402 for contacting the micro switch 3. The microswitch 3 of the lifting rod press-activated structure is installed inside the end cover 2, which is mounted on the lifting rod 1. The end cap 4 is mounted on the lifting rod 1 and covers the end cover 2, effectively preventing water or oil from entering the microswitch 3 and causing malfunction. A first protrusion 401 and a second protrusion 402 are formed on the inner side of the pressing surface of the end cap 4. When it is necessary to control the lifting rod 1 to move up and down, the user can directly press the pressing surface of the end cap 4, causing the first protrusion 401 and the second protrusion 402 to move closer to the end cover 2. When the second protrusion 402 touches the microswitch 3... When the micro switch 3 comes into contact, it sends an action signal to the drive device, causing the lifting rod 1 to perform a corresponding action. At the same time, the first protrusion 401 comes into contact with the upper surface of the end cover 2, which can prevent the second protrusion 402 from excessively squeezing the micro switch 3. Moreover, the signal line of the micro switch 3 passes through the mounting hole 201 and extends into the lifting rod 1, avoiding repeated folding or squeezing of the signal line, which helps to extend the service life of the micro switch 3. It has the advantages of simple structure, small size, high reliability and stability, and good ease of use.

[0025] Preferably, the lifting rod 1 has a cavity 101, and the end cap 2 has a plug 202 and an inner extension 203. The inner extension 203 passes through the cavity 101, and the plug 202 abuts against the end of the lifting rod 1, which can effectively improve the connection stability of the end cap 2 on the lifting rod 1 and enhance the reliability of the press-to-start structure.

[0026] Preferably, the lifting rod 1 is provided with several sets of through holes 102, and the inner extension 203 is provided with several sets of positioning holes 204. Fasteners pass through the through holes 102 and are installed in the positioning holes 204 so that the end cap 2 is fixedly connected to the lifting rod 1. This has the advantages of simple structure and convenient and quick assembly and disassembly.

[0027] Preferably, the inner side wall of the end cap 4 is formed with a limiting protrusion 403 for abutting against the plug 202, and a deformation chamber 404 is formed on the side of the end cap 4 away from the plug 202. In this embodiment, the limiting protrusion 403 is formed on the inner side wall of the end cap 4. When the end cap 4 is installed on the lifting rod 1, the limiting protrusion 403 can abut against the plug 202 of the end cap 2, making it convenient for the operator to install the end cap 4 in a suitable position. The deformation chamber 404 is formed on the side of the end cap 4 near the pressing surface. The wall thickness of the deformation chamber 404 is relatively thin, making it easy to deform under external force. This allows the user to press the pressing surface with their finger, thereby driving the second protrusion 402 to abut against the micro switch 3 to activate the device, resulting in good ease of use.

[0028] Preferably, the plug 202 has a cavity 205 formed therein, and the mounting hole 201 is located within the cavity 205. The second protrusion 402 can be deformed by the pressing surface of the end cap 4 and extend into the mounting hole 201 to abut against the micro switch 3. The first protrusion 401 can be deformed by the pressing surface of the end cap 4 and extend into the cavity 205 to abut against the upper end surface of the cavity 205. In this embodiment, by providing the cavity 205 on the plug 202, the distance between the first protrusion 401 and the upper end surface of the plug 202, as well as the distance between the second protrusion 402 and the micro switch 3, is increased. That is, the pressing surface of the end cap 4 needs to undergo a large deformation to trigger the micro switch 3, which can effectively prevent accidental activation.

[0029] Preferably, a limiting groove 206 is provided in the mounting hole 201, and a limiting protrusion 301 is provided on the micro switch 3. The limiting protrusion 301 abuts against the limiting groove 206 to position the micro switch 3 within the mounting hole 201. In this embodiment, when the micro switch 3 is installed inside the end cover 2, it can be directly placed in the mounting hole 201. The abutment between the limiting protrusion 301 and the limiting groove 206 keeps the micro switch 3 in a stable vertical position within the mounting hole 201. The limiting groove 206 provides support when the micro switch 3 is pressed, ensuring its normal operation. During maintenance and replacement, the micro switch 3 can be easily lifted out of the mounting hole 201, offering the advantages of convenient and quick installation and removal, and high maintenance efficiency.

[0030] Preferably, the end cap 4 is a one-piece molded structure made of flexible material. In this embodiment, the end cap 4 is mainly molded by a one-piece injection molding process, which has the advantages of good quality stability and low cost.

[0031] Preferably, the flexible material is silicone. In this embodiment, the end cap 4 is made of silicone, which is an environmentally friendly and safe food-grade material that does not contain toxic substances, has a wide applicable temperature range, and is suitable for use in the noodle basket lifting device of a noodle cooker. Moreover, silicone has good resilience and tear resistance, which can effectively extend the service life of the end cap 4.

[0032] The above description is merely a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. For those skilled in the art, improvements and modifications obtained without departing from the technical concept of this utility model should also be considered within the protection scope of this utility model.
