Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of heating pipe testing, and particularly relates to a new type of heating pipe testing device. Background Technique
[0002] A heating pipe usually consists of an inner and an outer metal pipe, with an electric heating wire filled in the middle. When powered on, the current passes through the heating wire, generating a large amount of resistive heat. This heat is conducted to the metal pipe wall, increasing the temperature of the metal pipe wall. Part of the heat is radiated from the metal pipe wall, while most of the heat is transferred to the object or medium to be heated through convection.
[0003] Currently, the heating pipe testing on the market is all carried out after assembling the shell. First, connect the assembled heating pipe, connect the lower water inlet to the water inlet hose, and the upper water outlet to the drainage hose. Fix the heating body on the test bench, connect the water outlet NTC wire of the heating body to the test bench, detect the water temperature, clamp the power-on chuck to the terminal on the thermostat, and start the heating component of the device to be powered on for testing. For this solution, 1: If there is an abnormality in the heating pipe during the test, it is not easy to be detected because the heating pipe is already wrapped by the outer shell. 2: The operation of the employee is cumbersome and the efficiency is slow. 3: It is necessary to manually clamp the electric chuck to the terminal on the thermostat, and the operation is cumbersome. 4: The installation of the heating pipe and the connection method of the NTC wire are cumbersome. Content of the Utility Model
[0004] The purpose of the utility model is to provide a new type of heating pipe testing device to solve the problems raised in the above background technique.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A new type of heating pipe testing device includes a base. Above the base, a connecting plate is installed. Below the connecting plate, a slide rail is provided. A slider is slidably installed on the slide rail. One side of the slider is fixed with an L-shaped plate. On one side of the surface of the L-shaped plate, a positioning disk is installed. An upper sleeve and a lower sleeve are respectively provided on both sides. The lower sleeve passes through the L-shaped plate and is sleeved with an upper support column. Concentrically below the upper support column, a lower support column is provided; a heating pipe is placed between the upper support column and the lower support column. Contact pieces are provided at both ends of the heating pipe. A side plate is installed on the side of the L-shaped plate. Displacement rods are installed at both ends of the side plate. A contact point is provided at the bottom end of the displacement rod. A pushing mechanism is provided on the connecting plate, and the tail end of the pushing mechanism is installed in the upper sleeve. The pushing mechanism is used to drive the displacement of the slider.
[0007] Further, the direction of the contact point on the displacement rod is downward.
[0008] Furthermore, rubber rings are provided around the upper support column and the lower support column. The maximum displacement distance of the heating tube is limited by the rubber rings. When the adjusting slider is displaced, the two end surfaces of the heating tube will contact the rubber rings on the upper support column and the lower support column. Under the extrusion effect, the rubber rings form seals at both ends of the heating tube, ensuring the sealing effect inside the heating tube, effectively preventing external air, moisture or other impurities from entering the inside of the heating tube, and thus ensuring the purity of the internal environment of the heating tube.
[0009] Furthermore, a spring is sleeved on the displacement rod, and the spring acts between the contact point and the side plate.
[0010] Furthermore, a contact head is inserted into the side of the positioning disk, and the tail end of the contact head is connected to an NTC wire. The NTC wire usually consists of an NTC thermistor, a wire and a connector, and is used to measure and monitor the temperature change of the environment or equipment. The contact head enters the lower sleeve. When water is introduced into the heating tube, the water will enter the lower sleeve and be contacted by the contact head, so as to monitor the heating degree of the water temperature. In this way, there is no need to manually insert the NTC wire. After fixing the heating tube on the lower support column and the upper support column, when water is introduced, the water temperature can be directly measured by the NTC wire.
[0011] Furthermore, the pushing mechanism includes a double-headed frame. The top end of the double-headed frame is hinged with an L-shaped handle. The corner of the L-shaped handle is hinged with a connecting block. One end of the connecting block is hinged with a sliding rod. A cylindrical barrel is provided at the bottom of the double-headed frame. A round hole is provided at the top of the upper sleeve. The sliding rod passes through the cylindrical barrel and is connected in the round hole.
[0012] Furthermore, a positioning bolt is threadedly engaged with the outside of the upper sleeve. Insert the sliding rod into the round hole and tighten it with the positioning bolt, that is, the sliding rod is fixed to the upper sleeve. This installation method is simple in the installation process and can directly facilitate the subsequent disassembly of the slider, that is, the maintenance work of the equipment is convenient.
[0013] The technical solution of the present utility model has the following beneficial effects:
[0014] 1. By sliding the slider up and down, the distance between the upper support column and the lower support column can be easily adjusted, so that the heating tube can be conveniently installed between the two support columns. This operation method is simple and fast, reduces the operation difficulty, improves the work efficiency, and is applicable to heating tubes with different heights. Moreover, the upper support column and the lower support column can stably support the heating tube, ensuring that the heating tube will not shake or displace during the test.
[0015] 2. Slide the slider downward. The contacts at the bottoms of the two displacement rods will simultaneously contact two contact pieces on the outer wall of the heating tube. The contact pieces are positive and negative conductive pieces. The circuit is conducted by the displacement rods to supply power to the heating tube. When the contacts at the bottoms of the displacement rods contact the contact pieces, the springs will compress to provide a downward thrust, so that the contacts fit tightly with the contact pieces. This reduces signal interruption or weakening caused by poor contact.
[0016] 3. The contact head enters the lower sleeve. When water is introduced into the heating tube, the water will enter the lower sleeve and be contacted by the contact head, so as to monitor the heating degree of the water temperature. In this way, there is no need to manually insert the NTC wire. The heating tube is fixed on the lower support column and the upper support column, and when water is introduced, the water temperature can be directly measured by the NTC wire.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0025] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.
[0026] Embodiment 1:
[0027] Refer to Figure 1 , a new type of heating tube testing device, including a base 10, a connecting plate 12 is installed above the base 10, a slide rail 11 is provided below the connecting plate 12, a slider 14 is slidably installed on the slide rail 11, an L-shaped plate 15 is fixed on one side of the slider 14, a positioning disk 16 is installed on one side of the surface of the L-shaped plate 15, an upper sleeve 19 and a lower sleeve 20 are respectively provided on both sides, the lower sleeve 20 passes through the L-shaped plate 15 and is sleeved with an upper support column 26, and a lower support column 25 is concentrically provided below the upper support column 26;
[0028] In the above solution, elliptical grooves are provided on both sides of the base 10. The base 10 is installed on a vertical wall or a workbench, and bolts are driven into the elliptical grooves to stabilize the base 10. For the installation of the slide rail 11 and the slider 14, the slide rail 11 and the slider 14 can be rotated and arranged in structures such as T-shaped, rectangular, cylindrical, etc. to cooperate with each other to realize the installation of the slider 14 for displacement. When the slider 14 slides on the slide rail 11, it will synchronously drive the L-shaped plate 15, the positioning disk 16, and the upper support column 26 to move up and down. The lower support column 25 is installed on the horizontal surface of the workbench or the desktop.
[0029] A heating tube 30 is placed between the upper support column 26 and the lower support column 25. When testing the heating tube 30, first push the slider 14 upward. The upper support column 26 follows the slider 14 and moves upward, so that the distance between the upper support column 26 and the lower support column 25 increases. At this time, take the heating tube 30 to be tested. First, sleeve the bottom end of the heating tube 30 on the lower support column 25, and then move the slider 14 downward, that is, the distance between the upper support column 26 and the lower support column 25 becomes smaller, so that the top end of the heating tube 30 is sleeved on the upper support column 26, thus completing the installation and fixation of the heating tube 30. By sliding the slider 14 up and down, the distance between the upper support column 26 and the lower support column 25 can be easily adjusted, so that the heating tube 30 can be conveniently installed between the two support columns. This operation method is simple and fast, reduces the operation difficulty, and improves the work efficiency. Since the slider can flexibly adjust the distance between the support columns, the device can adapt to heating tubes of different lengths and sizes. This flexibility makes the device have a wider application range and can meet different test requirements. Moreover, the upper support column 26 and the lower support column 25 can stably support the heating tube 30 to ensure that the heating tube 30 will not shake or displace during the test. Water inlets and outlets (not clearly marked in the figure) are provided on the outer wall of the heating tube 30. Hoses are respectively connected to the water inlets and outlets. Water enters the inside of the heating tube 30 from the water inlet, and the functions of pumping and delivering water are completed by connecting an external water pump through the hose.
[0030] Further, rubber rings 33 are provided around the upper support column 26 and the lower support column 25. The maximum displacement distance of the heating tube 30 is limited by the rubber rings 33. When adjusting the displacement of the slider 14, the two end surfaces of the heating tube 30 will contact the rubber rings 33 on the upper support column 26 and the lower support column 25. Under the extrusion effect, the rubber rings 33 form a seal at both ends of the heating tube 30, ensuring the sealing effect inside the heating tube 30, effectively preventing external air, moisture or other impurities from entering the heating tube, and thus ensuring the purity of the internal environment of the heating tube. It also effectively prevents possible liquid leakage of the heating tube during the test, ensures the stability of the test environment, and improves the accuracy of the test.
[0031] Reference Figure 1 、 Figure 2 and Figure 6 As shown in, contact pieces 31 are provided at both ends of the heating tube 30. Side plates 151 are installed on the side surface of the L-shaped plate 15. Displacement rods 27 are installed at both ends of the side plates 151. Contact points 28 are provided at the bottom ends of the displacement rods 27, and the directions of the contact points 28 on the displacement rods 27 are downward;
[0032] In the above solution, according to Figure 6In it, the side plate 151 is fixed to the side of the L-shaped plate 15. Similarly, when the slider 14 moves, it will also drive the side plate 151 to move synchronously. When the slider 14 moves downward, the contacts 28 at the bottoms of the two displacement rods 27 will simultaneously contact two contact pieces 31 on the outer wall of the heating tube 30. The contact pieces 31 are positive and negative conductive pieces, and the circuit is conducted by the displacement rods 27 to supply power to the heating tube 30, thus completing the heating function of the heating tube 30. The water passing and power-on test of the heating tube 30 is completed.
[0033] Further, a spring 29 is sleeved on the displacement rod 27, and the spring 29 acts between the contact 28 and the side plate 151. When the contact 28 at the bottom of the displacement rod 27 contacts the contact piece 31, the spring 29 will compress to provide a downward thrust, so that the contact 28 fits tightly with the contact piece 31. Thus, the signal interruption or weakening caused by poor contact is reduced.
[0034] Further, a contact head 17 is inserted into the side of the positioning disk 16, and an NTC wire 18 is connected to the tail end of the contact head 17. The NTC wire 18 usually consists of an NTC thermistor, a wire and a connector, and is used to measure and monitor the temperature change of the environment or equipment. The contact head 17 enters the lower sleeve 20. When water is introduced into the heating tube 30, the water will enter the lower sleeve 20 and be contacted by the contact head 17, so as to monitor the heating degree of the water temperature. In this way, there is no need to manually insert the NTC wire. The heating tube 30 is fixed on the lower support column 25 and the upper support column 26, and when water is introduced, the water temperature can be directly measured by the NTC wire.
[0035] Embodiment 2:
[0036] Reference Figures 3 - 6 , a pushing mechanism is provided on the connecting plate 12, and the tail end of the pushing mechanism is installed in the upper sleeve 19. The pushing mechanism is used to drive the slider 14 to move. The pushing mechanism includes a double-headed frame 13. The top end of the double-headed frame 13 is hinged with an L-shaped handle 24. The corner of the L-shaped handle 24 is hinged with a link block 23. One end of the link block 23 is hinged with a sliding rod 22. A cylindrical barrel 131 is provided at the bottom of the double-headed frame 13, and a round hole 21 is provided at the top of the upper sleeve 19. The sliding rod 22 passes through the cylindrical barrel 131 and is connected in the round hole 21.
[0037] In the above solution, when it is necessary to adjust the displacement of the slider 14, one only needs to hold the L-shaped handle 24 with force by hand and flip the L-shaped handle 24. The link block 23 will pull the slide bar 22 to slide inside the cylinder 131. Since the slide bar 22 passes through the cylinder 131 and is connected to the round hole 21, the upper sleeve 19 will be driven to be stressed synchronously, that is, the upper sleeve 19 drives the slider 14 to displace synchronously. Flipping the L-shaped handle 24 can easily adjust the displacement of the slider 14. This operation method is simple and intuitive, without the need for complex tools or equipment. The L-shaped design of the L-shaped handle 24 enables the operator to precisely control the flipping angle and force, thereby achieving precise control of the displacement of the slider 14. This precise control helps to ensure that the heating tube 30 is accurately installed and fixed. Due to the linkage between the link block 23, the slide bar 22 and the upper sleeve 19, the force of the hand can be efficiently transmitted to the slider 14, so that a large displacement can be achieved with a small force. This not only saves the physical strength of the operator but also improves work efficiency.
[0038] Embodiment Three:
[0039] Reference Figure 3 , a positioning bolt 32 is engaged with the outer thread of the upper sleeve 19.
[0040] In this embodiment, the slide bar 22 is inserted into the round hole 21 and tightened by the positioning bolt 32, that is, the slide bar 22 is fixed to the upper sleeve 19. Such an installation method has a simple installation process and can directly facilitate the subsequent disassembly of the slider 14, that is, the maintenance work of the equipment is convenient.
[0041] The specific implementation process of this embodiment is as follows:
[0042] During use, when testing the heating tube 30, first push the slider 14 upward. The upper support column 26 follows the slider 14 to displace upward, so that the distance between the upper support column 26 and the lower support column 25 increases. At this time, take the heating tube 30 to be tested. First, set the bottom end of the heating tube 30 on the lower support column 25, and then displace the slider 14 downward, that is, the distance between the upper support column 26 and the lower support column 25 becomes smaller, so that the top end of the heating tube 30 is set on the upper support column 26, thus completing the installation and fixation of the heating tube 30. Displace the slider 14 downward, and the contacts 28 at the bottoms of the two displacement rods 27 will simultaneously contact two contact pieces 31 on the outer wall of the heating tube 30. The contact pieces 31 are positive and negative conductive pieces, and the displacement rods 27 conduct the circuit to supply power to the heating tube 30, thus completing the heating function of the heating tube 30.
[0043] When adjusting the displacement of the slider 14, one only needs to hold the L handle 24 with force by hand and turn the L handle 24. The link block 23 will pull the slide bar 22 to slide inside the cylinder 131. Since the slide bar 22 passes through the cylinder 131 and is connected to the round hole 21, the upper sleeve 19 will be driven to be stressed synchronously, that is, the upper sleeve 19 drives the slider 14 to displace synchronously.
