Description

Technical Field

[0001] This utility model belongs to the field of ultrasonic heat meter technology, specifically an ultrasonic heat meter with room temperature monitoring function. Background Technology

[0002] An ultrasonic heat meter measures flow rate using ultrasonic waves and calculates the consumed heat energy based on the temperature difference between the supply and return water. It is widely used for heating metering in residential and public buildings.

[0003] Currently, existing ultrasonic heat meters are usually connected to external pipes using flange connections, which require multiple bolts and nuts for fixing. During installation and maintenance, each bolt and nut needs to be tightened or loosened individually, which is cumbersome and time-consuming, especially in confined spaces where disassembly and assembly are even more inconvenient. Utility Model Content

[0004] In view of the above situation and to overcome the shortcomings of the prior art, this utility model provides an ultrasonic heat meter with room temperature monitoring function, which effectively solves the problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ultrasonic heat meter with room temperature monitoring function, comprising a connecting pipe, a meter body fixedly connected to the top of the connecting pipe, a room temperature monitoring device body fixedly connected to the front side of the meter body, external pipes provided on both sides of the connecting pipe, threaded sleeves rotatably connected to both sides of the connecting pipe, the inner wall of the threaded sleeves being connected to the external threads of the external pipes, insertion rods fixedly installed on the upper and lower parts of both sides of the connecting pipe, sealing gaskets movably sleeved on the outside of the insertion rods on both sides, and limit mechanisms provided on both sides of the connecting pipe.

[0006] Preferably, the limiting mechanism includes a hollow annular seat fixedly sleeved on the outside of the connecting pipe, a support rod symmetrically connected inside the hollow annular seat, a movable plate slidably sleeved on the outside of the support rod, a spring fixedly connected to one side of the movable plate, one end of the spring fixedly connected to the inner wall of the hollow annular seat, and the spring sleeved on the outside of the support rod.

[0007] Preferably, a positioning rod is fixedly connected to one side of the movable plate, and one side of the positioning rod extends through to the outside of the hollow annular seat. One side of the movable plate extends through to the outside of the hollow annular seat, and an annular plate is provided on the outside of the hollow annular seat. The inner wall of the annular plate is fixedly connected to one side of the movable plate.

[0008] Preferably, the hollow annular seat has rectangular holes at both the top and bottom, and the outer side of the moving plate slides in contact with the inner wall of the rectangular holes.

[0009] Preferably, slots are provided on both the upper and lower parts of one side of the external pipe, and the insertion rod is engaged with the slot.

[0010] Preferably, one side of the threaded sleeve is provided with a ring-shaped array of positioning grooves, and the positioning rod is engaged with the positioning grooves.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model uses a rotating threaded sleeve to move the threaded external pipe to one side, causing the insertion rod to move away from the slot. This allows for manual tightening or loosening without the need for tools, making the operation more convenient.

[0013] 2. This new type of device moves a sliding annular plate to one side, which in turn moves a movable plate to one side. Simultaneously, the spring is compressed, and the movable plate moves a positioning rod to one side, moving the positioning rod away from the positioning groove on the threaded sleeve. This limits the positioning of the threaded sleeve, prevents it from loosening, and improves the practicality of the device. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example 1, by Figures 1-5 The present invention includes a connecting pipe 1, a meter body 2 fixedly connected to the top of the connecting pipe 1, a room temperature monitoring device body 3 fixedly connected to the front side of the meter body 2, external pipes 4 provided on both sides of the connecting pipe 1, threaded sleeves 5 rotatably connected to both sides of the outside of the connecting pipe 1, the inner wall of the threaded sleeves 5 being threadedly connected to the outside of the external pipes 4, insertion rods 6 fixedly installed on the upper and lower parts of both sides of the connecting pipe 1, sealing gaskets 7 movably sleeved on the outside of the insertion rods 6 on both sides, and limit mechanisms 8 provided on both sides of the outside of the connecting pipe 1.

[0024] The limiting mechanism 8 includes a hollow annular seat 801 fixedly sleeved outside the connecting pipe 1. A support rod 802 is symmetrically connected inside the hollow annular seat 801. A movable plate 803 is slidably sleeved outside the support rod 802. A spring 805 is fixedly connected to one side of the movable plate 803. One end of the spring 805 is fixedly connected to the inner wall of the hollow annular seat 801. The spring 805 is sleeved on the outer side of the support rod 802. A positioning rod 804 is fixedly connected to one side of the movable plate 803. One side of the positioning rod 804 extends through to the outside of the hollow annular seat 801. One side of the movable plate 803 extends through to the outside of the hollow annular seat 801. An annular plate 806 is provided outside the hollow annular seat 801. The inner wall of the annular plate 806 is fixedly connected to one side of the movable plate 803.

[0025] A movable plate 803 is slidably sleeved on the outside of the support rod 802. The movable plate 803 can slide flexibly along the axis of the support rod 802. A spring 805 is fixedly connected to one side of the movable plate 803. One end of the spring 805 is fixedly connected to the inner wall of the hollow annular seat 801 and is sleeved on the outside of the support rod 802. This allows the spring 805 to generate a uniform elastic force when the movable plate 803 slides, providing a reset power for the movable plate 803.

[0026] The hollow annular seat 801 has rectangular holes 807 at both the top and bottom. The outer side of the movable plate 803 slides in contact with the inner wall of the rectangular hole 807. The upper and lower parts of one side of the external pipe 4 have slots 10. The insertion rod 6 is engaged with the slot 10. The threaded sleeve 5 has a ring array of positioning grooves 9 on one side. The positioning rod 804 is engaged with the positioning grooves 9.

[0027] The positioning grooves 9 are arranged at equal angular intervals. When the positioning rod 804 is engaged in the positioning grooves 9 at different positions, the rotation angle of the threaded sleeve 5 can be precisely limited.

[0028] Working principle: In use, by sliding the annular plate 806 to one side, the annular plate 806 drives the moving plate 803 to one side, while compressing the spring 805. The moving plate 803 drives the positioning rod 804 to one side, so that the positioning rod 804 is away from the positioning groove 9 on the threaded sleeve 5. Then, the threaded sleeve 5 is rotated, and the threaded sleeve 5 drives the threaded external pipe 4 to one side, so that the insertion rod 6 is away from the slot 10, which can quickly assemble and disassemble the connecting pipe 1 and the external pipe 4.
