[0026] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0027] like Figures 1 to 3 As shown, a wiring guide frame according to one embodiment of this utility model includes a pair of clamps 1 hinged together, a wire guide cover 2, and a sealing cover 3. A fixing bolt 101 connects the pair of clamps 1. The wire guide cover 2 is fixedly connected to one of the clamps 1. A pair of winding frames 201 are connected inside the wire guide cover 2. The pair of winding frames 201 are symmetrical and cooperate with each other for winding the wire. The wound wire is housed inside the wire guide cover 2. The sealing cover 3 covers the port of the wire guide cover 2.

[0028] The lead wire cover 2 can be fixed to the mass flow meter by the cooperation of a pair of clamps 1 and fixing bolts 101. The lead wire of the mass flow meter can be wound using a pair of winding frames 201. Covering the port of the lead wire cover 2 with the sealing cover 3 will store the wound lead wire inside the lead wire cover 2.

[0029] This application features a simple wiring structure for the lead wires, without complex transmission components, thus ensuring the normal service life of the lead wire cover 2 and enabling it to better guide the mass flow meter's lead wires. Simultaneously, housing the mass flow meter's lead wires within the lead wire cover 2 protects them from external environmental influences.

[0030] like Figures 1 to 3As shown, the lead wire cover 2 has a pair of notches 202, and the included angle between the pair of notches 202 ranges from 30° to 180°. The notches 202 are used for the passage of the lead wire so that other devices can be connected to the mass flow meter via the lead wire.

[0031] Preferably, the included angle between the pair of notches 202 is 180° to facilitate the passage of the lead wire.

[0032] Among them, multiple fixing seats 203 are fixedly connected to the lead wire cover 2. The lead wire cover 2, the winding frame 201 and the fixing seats 203 are integrally formed, which can ensure the integrity of the connection between the lead wire cover 2, the winding frame 201 and the fixing seats 203.

[0033] like Figures 1 to 3 As shown, multiple connecting seats 301 are fixedly connected to the sealing cover 3, and each connecting seat 301 corresponds one-to-one with a multiple fixing seat 203. Bolts 302 connect the connecting seats 301 and the fixing seats 203. The bolts 302 are used to fix the connecting seats 301 and the fixing seats 203, thereby fixing the sealing cover 3 to the port of the lead wire cover 2. Figure 1 The state shown. When the lead wire is wound on a pair of winding frames 201, the sealing cover 3 is used to cover the port of the lead wire cover 2, so that the lead wire can be stored in a relatively enclosed space to reduce the influence of the external environment on the lead wire.

[0034] The sealing cover 3 has a handle post 303 fixedly connected to the side away from the lead wire cover 2, which facilitates the separation of the lead wire cover 2 and the sealing cover 3.

[0035] In addition, a pair of sealing elements 304 are fixedly connected to the sealing cover 3. The pair of sealing elements 304 are respectively disposed in a pair of notches 202, and the sealing elements 304 are provided with clearance grooves 305. When the sealing cover 3 covers the port of the lead wire cover 2, the sealing elements 304 can be inserted into the notches 202. At this time, the lead wire can pass through the clearance grooves 305. By using the sealing elements 304, the opening area of ​​the notches 202 can be reduced, thereby further reducing the probability that the lead wire inside the lead wire cover 2 is affected by the external environment.

[0036] Specifically, the sealing cover 3, the connecting seat 301, the handle post 303, and the sealing component 304 are integrally formed.

[0037] like Figure 4 As shown, this utility model also discloses a mass flow meter, including a wiring guide frame and a mass flow meter body 4. The wiring guide frame is installed on the mass flow meter body 4 so as to guide the storage of the leads of the mass flow meter body 4.

[0038] In summary, this application utilizes the cooperation of a pair of clamps 1 and fixing bolts 101 to fix the lead wire cover 2 to the mass flow meter body 4, as shown below. Figure 4As shown. The lead wire of the mass flow meter body 4 can pass through one of the notches 202 and be wound on a pair of winding frames 201, with the other end of the lead wire passing through the notch 202.

[0039] The connector 301 is fixed to the fixing base 203 using bolts 302, and then the sealing cover 3 can be placed over the lead wire cover 2 port. Figure 4 The state shown is such that the lead wires of the mass flow meter body 4 can be stored in the relatively sealed space of the lead wire cover 2, making the lead wires less susceptible to the influence of the external environment.

[0040] This application features a simple wiring structure for the lead wires, without complex transmission components, thus ensuring the normal service life of the lead wire cover 2 and enabling it to better guide the mass flow meter's lead wires. Simultaneously, housing the mass flow meter's lead wires within the lead wire cover 2 protects them from external environmental influences.
