Description

Technical Field

[0001] The invention relates to the technical field of HVAC pipe processing, in particular to auxiliary docking equipment for HVAC pipe installation. Background Art

[0002] The thickness and specifications of HVAC pipes can be changed according to requirements. Usually, when connecting, both ends of the duct are always connected to accessories (such as elbows and reducers). Generally, there are no grooves at both ends of HVAC pipes and they are equipped with sealing rings. HVAC equipment has been widely used in buildings in recent years. It can provide heating, ventilation, air conditioning and other functions to make the indoor air more comfortable and suitable for living. HVAC equipment needs to be installed with pipes during the installation process, so auxiliary docking equipment is needed to dock and install the pipes of HVAC parts.

[0003] At present, when using the auxiliary docking equipment for HVAC pipe installation on the market, it is necessary to heat the two pipes and then form a plug-in to complete the auxiliary docking of the two pipes. Only pipes of one model diameter can be docked each time. Therefore, the applicability of the docked pipes is poor, and batch docking of multiple models and diameters is impossible. Therefore, it is inconvenient to use. In the related technology, holes of different sizes are opened on the positioning plate to limit HVAC pipes of different sizes. However, in actual use, its function is relatively single. Not only can it not limit the HVAC pipes of the same model, but it can also not limit the HVAC pipes of other models, which brings inconvenience to use. Summary of the invention

[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0040] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0041] In addition, in this application, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0042] When using the auxiliary docking equipment for HVAC pipe installation, the two pipes need to be heated and then plugged in to complete the auxiliary docking of the two pipes. Only pipes of one model diameter can be docked at a time. Therefore, the applicability of the docked pipes is poor, and batch docking of multiple models and diameters is not possible, making it inconvenient to use.

[0043] In the related art, holes of different sizes are opened on the positioning plate to limit the HVAC pipes of different sizes. However, in actual use, its function is relatively single. It cannot limit the HVAC pipes of the same model, nor can it limit the HVAC pipes of other models, which brings inconvenience to use.

[0044] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides an auxiliary docking device for the installation of HVAC pipes. When it is needed, it is only necessary to adjust the height of the multiple clamps 124, turn on the electric push rod 122, and limit the HVAC pipes of different sizes. Through the adjustment mechanism 11, the clamps 124 and 126 are adjusted, and the HVAC pipes are pulled to move, which is convenient for subsequent docking operations, faster and more convenient, and improves the convenience of the device.

[0045] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0046] Combination Figure 1-Figure 6, the embodiment of the present application provides an auxiliary docking device for HVAC pipe installation, comprising: a box body 10, on which an adjustment mechanism 11 is arranged, a slide rail 15 is fixedly connected to the top of the box body 10, a clamping mechanism 12 is slidably connected to the slide rail 15, the adjustment mechanism 11 is used to adjust the position of the clamping mechanism 12, a resistance heating plate 13 is arranged on the top of the box body 10, and a heat conductive block 14 is installed on the top of the resistance heating plate 13; the clamping mechanism 12 comprises: a frame body 121, which is slidably connected to the slide rail 15 and connected to the adjustment mechanism 11, an electric push rod 122 is fixedly connected to the frame body 121, a mounting plate 123 is arranged at the output end of the electric push rod 122, a clamping block 124 is arranged at the bottom of the mounting plate 123, a mounting plate 2 125 is fixedly connected to the inner side of the frame body 121, and a clamping block 2 126 is fixedly connected to the top of the mounting plate 125; the mounting plate 123 A mounting block 20 is slidably connected inside, and a hole 21 is opened on the side of the mounting block 20. A round head rod 22 is slidably connected to the mounting plate 123. One end of the round head rod 22 is inserted into the hole 21. A spring 23 is sleeved on the outer side of the round head rod 22. The round head rod 22 is connected to the mounting plate 123 through the spring 23. A clamping block 124 is provided on the mounting plate 123. The round head rod 22 passes through the push plate 25. The mounting plate 123 is fixedly connected with a limit plate 130, and the limit plate 130 is slidably connected with a limit plate 21. A slot 32 is provided on the mounting block 20, and the limit plate 21 is connected to the limit plate 130 via a spring 233. One end of the limit rod 24 is inserted into the limit plate 130, and the outer side of the limit rod 24 is fixedly connected with a limit ring 40, and the limit ring 40 is connected to the limit plate 130 via a spring 31.

[0047] After the box 10 is installed at the designated position, the designated round-headed rod 22 is pulled outward to make the round-headed rod 22 slide outward and one end of the round-headed rod 22 slide outward, and the spring 1 23 is pulled to cancel the limit of the height of the designated mounting block 20, and then the corresponding mounting block 20 is directly pulled to make it slide downward from the mounting plate 123 and drive the clamping block 124 to slide. After adjusting the height of the clamping block 124, the round-headed rod 22 is released, and one end of the round-headed rod 22 is inserted into another hole 21 through the rebound force of the spring 1 23, and the mounting block 20 is fixed. The height of the plurality of mounting blocks 20 is fixed, and the heights of the plurality of mounting blocks 20 are adjusted in turn, so that the plurality of clamping blocks 124 are at different heights, and finally the HVAC pipe to be connected is placed on the clamping block 2 126, and the electric push rod 122 is turned on, so that the output end of the electric push rod 122 pushes the mounting plate 123 and the plurality of clamping blocks 124 to slide downward, so that the clamping blocks of different heights can clamp and fix the HVAC pipes of different sizes respectively, and the heights of the plurality of clamping blocks 124 can also be adjusted to the same height, so as to realize the clamping and limiting of multiple HVAC pipes of the same type at the same time, and finally the electric push rod 122 is turned on. The adjusting mechanism 11 is started to adjust the frame 121 in the clamping mechanism 12, so that the frame 121 slides on the box body 10, and the frame 121 is limited by the slide rail 15, so that the frame 121 drives the electric push rod 122, the mounting plate 123, the clamping block 124 and the HVAC pipe to move at the same time, and after the HVAC pipe contacts the heat conductive block 14 on the resistance heating plate 13, the resistance heating plate 13 is energized for heating, and then the resistance heating plate 13 heats the multiple heat conductive blocks 14, and the multiple heat conductive blocks 14 heat the outer wall of the HVAC pipe. In addition, a curved surface is provided on the heat conducting block 14, so that the end of the HVAC pipe on one side is deformed and the diameter is increased, which facilitates the subsequent insertion of the HVAC pipe on the other side into the deformed HVAC pipe. After heating is completed, the height of the resistance heating plate 13 is adjusted to make the resistance heating plate 13 lower than the clamping block 2 126, and then the adjustment mechanism 11 is opened again to connect the two groups of HVAC pipes; the push plate 25 can also be pulled to make the push plate 25 drive multiple round head rods 22 to slide outward at the same time, so as to adjust the height of multiple clamping blocks 1 124 at the same time, and the limit rod 24 plays a limiting role on the push plate 25.

[0048] When adjusting the height of the mounting block 20, the second limiting plate 31 is made to slide in the slot 32 to prevent the mounting block 20 from falling off from the first mounting plate 123. Conversely, when the mounting block 20 needs to be disassembled, the second limiting plate 31 is pushed to slide in the first limiting plate 30 and the second spring 33 in the first limiting plate 30 is squeezed until the second limiting plate 31 slides out of the slot 32, and then the mounting block 20 is directly taken out from the first mounting plate 123.

[0049] When removing the mounting block 20, first pull the limit rod 24 outward so that the limit rod 24 drives the limit ring 40 to slide outward, and at the same time pull the spring three 41 until one end of the limit rod 24 slides out of the limit plate one 30, cancel the limit on the limit plate two 31, and finally pull the mounting block 20 so that the side slot 32 is in direct contact with the chamfer on the limit plate two 31, so that the mounting block 20 pushes the limit plate two 31 to slide into the limit plate one 30, which is convenient for subsequent disassembly operations. Conversely, through the rebound force of the spring three 41, one end of the limit rod 24 is inserted into the limit plate one 30, which limits the limit plate two 31. When pulling the mounting block 20, the limit plate one 30 will not slide into the limit plate two 31, thereby preventing the mounting block 20 from detaching.

[0050] Specifically, the resistance heating plate 13 is based on the I2R loss principle, which stipulates that if a current of I ampere flows through a conductor with a resistance of R ohms, the power generated in the conductor in the form of heat is I2R, which causes the body to heat up. In the case of resistance heating, we can use alternating current (AC) or direct current (DC) for heating. Resistance heating is used in different electrical appliances and industrial processes, such as electric irons, electric heaters, drying of pottery, baking, heat treatment of metals, etc., which belongs to the prior art, so it will not be described in detail.

[0051] In some embodiments, a through hole is provided on the push plate 25 so that the push plate 25 can pull the round head rod 22 without affecting the normal use of the spring 1 23 .

[0052] In some embodiments, the clamp block 124 is provided with an arc surface, so that the clamp block 124 can be clamped and limited with HVAC pipes of various different diameters.

[0053] In some embodiments, a fixing plate 50 is provided on the resistance heating plate 13, and the fixing plate 50 is connected to the resistance heating plate 13 by bolts 52. A heat conductive block 2 51 is fixedly connected to the inner side of the fixing plate 50, and the heat conductive block 14 is installed on the top of the heat conductive block 2 51.

[0054] When the heat conducting block 14 needs to be disassembled, the bolts 52 are first disassembled, and then the fixing plate 50 is directly removed from the resistance heating plate 13, and vice versa for installation.

[0055] In some embodiments, a slider 60 is slidably connected inside the slide rail 15, a movable plate 61 is fixedly connected to the slider 60, the slider 60 is connected to the inner side of the slide rail 15 via a spring 62, and one end of the movable plate 61 is inserted into the resistance heating plate 13.

[0056] When adjusting the position of the frame 121, the frame 121 slides outward, and at the same time, it pushes the movable plate 61 to slide in the slide rail 15, pulls the slider 60, and the slider 60 squeezes the spring four 62, and finally the movable plate 61 slides out of the resistance heating plate 13. After the limit on the resistance heating plate 13 is cancelled, it is convenient to install and disassemble the resistance heating plate 13.

[0057] In some embodiments, the movable plate 61 is L-shaped, so that the frame 121 can push the movable plate 61 easily.

[0058] In some embodiments, a lifting mechanism is provided in the box body 10 for adjusting the height of the resistance heating plate 13 , and the resistance heating plate 13 is plugged into the output end of the lifting mechanism to facilitate disassembly of the resistance heating plate 13 .

[0059] In some embodiments, the adjustment mechanism 11 is composed of a motor, a screw rod, a slider, a sprocket and a chain. By turning on the motor, it is connected through the transmission of the chain and the sprocket, and at the same time drives multiple screw rods to rotate, so that multiple sliders drive multiple frames 121 to move, thereby realizing the adjustment of the position of the frame 121.

[0060] In some embodiments, a guide block is fixedly connected to the side of the mounting plate 123 to make the up and down sliding of the mounting plate 123 more stable.

[0061] In some embodiments, the heat conductive block 14, the clamp block 124 and the clamp block 2 126 are a group, and multiple groups are provided to achieve simultaneous positioning of multiple HVAC pipes.

[0062] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", "some examples", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification.

[0063] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0064] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
