[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 5This utility model provides a technical solution: a heat metering device, including a metering instrument 1. A frame 2 is mounted at the front end of the metering instrument 1. An adjustment assembly is installed inside the frame 2. Two connecting rods 3 are mounted on the adjustment assembly. Two rotating columns 9 are mounted on each of the two connecting rods 3. Clamping plates 4 are mounted on each of the two rotating columns 9. Fixing grooves 10 are formed on each of the two clamping plates 4, which are inclined from the left and right sides towards the center. A driving assembly is mounted on the connecting rods 3. The driving assembly drives two gears 15 to rotate the rotating columns 9 and clamping plates 4, clamping the delivery pipe and causing the clamping rod 17 to be held in place by a spring. Under the elastic force of 19, it resets and inserts into the corresponding card hole 20 cavity, thereby fixing the position of rack 13, and thus fixing the angle of gear 15, rotating column 9 and clamping plate 4, thereby realizing the installation of the device. This solves the problem that the installation of heat metering equipment is complicated and troublesome, requiring the tightening of multiple bolts to complete the installation of the metering equipment, which consumes a lot of time. By adjusting the setting of the components, the distance between the two fixed components can be adjusted, which can be conveniently adjusted according to the actual installation situation, improving the flexibility of the device in use.

[0023] In this embodiment, the driving assembly includes a limiting assembly, a rack 13, gears 15, and a fixing assembly. The limiting assembly is located at one end of the connecting rod 3, and the rack 13 is located at the end of the assembly away from the connecting rod 3. Two gears 15 are respectively fixedly sleeved on the outer walls of the two rotating columns 9 and are meshed with each other. The fixing assembly is located on the rear side of the connecting rod 3. A top plate 14 is provided at the front end of the rack 13. When the rack 13 slides backward under the limiting action of the limiting groove 11 and the limiting block 12, since both gears 15 are meshed with the rack 13, the two gears 15 can drive the rotating columns 9 and the clamping plate 4 to rotate and clamp the conveying pipe. The clamping rod 17 is reset and inserted into the corresponding clamping hole 20 under the elastic force of the spring 19, thereby fixing the position of the rack 13 and fixing the angle of the gears 15, the rotating columns 9, and the clamping plate 4. This solves the problem that the installation of heat metering equipment is complicated and troublesome, requiring the tightening of multiple bolts to complete the installation of the metering equipment, which consumes a lot of time.

[0024] In this embodiment, the limiting component includes a limiting groove 11 and a limiting block 12. The limiting groove 11 is opened at one end of the connecting rod 3. The limiting block 12 is slidably embedded in the inner cavity of the limiting groove 11 and fixedly connected to the rack 13. Under the combined action of the limiting groove 11 and the limiting block 12, the rack 13 can always slide along a straight line. The inner cavity of the limiting groove 11 and the outer wall of the limiting block 12 are adapted to each other and are both in the shape of a "T". This ensures that one end of the limiting block 12 is always embedded in the inner cavity of the limiting groove 11, which improves the stability of the limiting component during use and prevents the limiting block 12 from disengaging from the inner cavity of the limiting groove 11, causing the rack 13 to disengage from the gear 15.

[0025] In this embodiment, the fixing assembly includes a fixing plate 16, a locking rod 17, a limiting plate 18, a spring 19, and locking holes 20. The fixing plate 16 is disposed on the outer wall of the connecting rod 3. The locking rod 17 is slidably inserted into the middle of the fixing plate 16. The limiting plate 18 is disposed at the end of the locking rod 17 away from the rack 13. The spring 19 is sleeved on the outer wall of the locking rod 17, and both ends of the spring 19 are fixedly connected to the fixing plate 16 and the limiting plate 18, respectively. Multiple locking holes 20 are all opened at the bottom end of the limiting block 12, and at the rack 13... When sliding backward, the locking rod 17 can be aligned with the corresponding locking hole 20. Under the elastic force of the spring 19, the limiting plate 18 can push the locking rod 17 upward to slide into the inner cavity of the locking hole 20, thereby fixing the position of the rack 13, and fixing the angle of the gear 15, the rotating column 9 and the clamping plate 4, thus realizing the installation of the device. This solves the problem that the installation and operation of heat metering equipment is complicated and troublesome, requiring the tightening of multiple bolts to complete the installation of the metering equipment, which consumes a lot of time.

[0026] In this embodiment, the top of the locking rod 17 is inclined, so that when the inner wall of the locking hole 20 presses the inclined surface of the locking rod 17, the locking rod 17 can slide downward, causing the spring 19 to stretch and generate corresponding elastic deformation, thereby generating corresponding elastic force.

[0027] In this embodiment, the adjustment assembly includes a lead screw 5, a knob 6, a guide rod 7, and a sliding plate 8. One end of the lead screw 5 is rotatably connected to the bottom of the inner cavity of the frame 2 via a bearing, and the other end of the lead screw 5 extends to the top of the frame 2 and is fixedly connected to the knob 6. The guide rod 7 is disposed in the inner cavity of the frame 2. Two sliding plates 8 are respectively screwed to the upper and lower sides of the outer wall of the lead screw 5 and are respectively fixedly connected to two connecting rods 3. Rotating the knob 6 causes the knob 6 to drive the lead screw 5 to rotate, thereby causing the opposing threads on the upper and lower sides of the outer wall of the lead screw 5 to generate opposing thread rotational forces. Under the limiting action of the guide rod 7, the two sliding plates 8 slide relative to each other simultaneously, allowing the distance between the two fixed components to be adjusted. This allows for convenient adjustment of the distance between the two fixed components according to the actual installation situation, improving the flexibility of the device during use.

[0028] In this embodiment, the threads on the upper and lower sides of the outer wall of the lead screw 5 are arranged opposite to each other, thereby generating a relative thread rotation force between the opposite threads on the upper and lower sides of the outer wall of the lead screw 5, so that the two slide plates 8 slide relative to each other simultaneously under the limiting action of the guide rod 7.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
