Description

Technical Field

[0001] This utility model relates to the field of hot water equipment technology, and in particular to a hot water equipment and a suspension structure therefor. Background Technology

[0002] Electric water heaters are experiencing strong growth in market share due to their safety, hygiene, and lack of pollution.

[0003] Currently, before installing an electric water heater, expansion bolts need to be installed on the wall to suspend it.

[0004] The following is a reference to the appendix. Figure 1 This document describes the structure of an expansion bolt 1 used for suspending an electric water heater in the related art and its installation process. It should be understood that the description of the related art herein is intended in part to provide useful background for understanding the art. However, this background art portion may also include viewpoints, concepts, or knowledge that were not part of what a person skilled in the art knew or understood prior to the corresponding valid application date of the subject matter disclosed herein.

[0005] Reference Figure 1 As shown, the expansion bolt 1 includes a screw 11, a spring sleeve 12 sleeved on the screw 11, and a movable nut 13. The movable nut 13 is located at the inner end and is threadedly connected to the screw 11. The spring sleeve 12 has multiple springs, and the openings of the multiple springs face the movable nut 13.

[0006] When installing expansion bolt 1, first drill a deep hole in the wall that matches the diameter and length of expansion bolt 1. Then, hammer expansion bolt 1, with the spring in a contracted state, into the deep hole. Then, rotate screw 11. At this time, moving nut 13 will move forward (outside the deep hole). Under the support of moving nut 13, the spring expands outward. The greater the distance that moving nut 13 moves forward, the larger the diameter of the spring expansion. In this way, the friction between the spring and the deep hole can be used to fix expansion bolt 1 in the deep hole of the wall.

[0007] However, the expansion bolt 1 in the above solution can only be used on relatively hard walls such as cement walls and brick walls. It cannot reliably fix soft walls such as wood walls and foam walls. This is because the hardness of soft walls is relatively small compared to cement walls and brick walls. The expansion bolt 1 is fixed in the deep hole by the friction between the spring and the deep hole. Thus, when an outward force is applied to the expansion bolt 1, the expanding spring can expand the inner wall of the deep hole drilled in the soft wall, causing the friction between the spring and the deep hole to decrease. This makes the expansion bolt 1 loose, which is not conducive to the stable installation of the electric water heater.

[0008] In view of the above, this utility model is hereby proposed. Utility Model Content

[0009] The technical problem to be solved by this utility model is to overcome at least some of the shortcomings of the prior art and provide a suspension structure for hot water equipment. By setting a fixed sleeve assembly and a movable sleeve assembly with a spring on the transmission rod, the movable sleeve assembly moves towards the fixed sleeve assembly under the transmission action of the transmission rod as the transmission rod rotates around its axis in a first direction. This causes the spring to expand outward under the support of the fixed sleeve assembly. When an outward force is applied to the suspension structure, the spring is stuck in the wall, making the suspension structure less prone to loosening and improving the installation stability of the hot water equipment.

[0010] To solve the above-mentioned technical problems, the first aspect of this utility model is to provide a suspension structure for a hot water equipment, comprising:

[0011] A transmission rod, which is rotatable about its axis, has an inner end and an outer end;

[0012] A fixed sleeve assembly is sleeved on the transmission rod near the outer end; and

[0013] A movable sleeve assembly is located on the side of the fixed sleeve assembly facing the inner end and is threadedly connected to the transmission rod. The movable sleeve assembly has at least two spring pieces, the openings of which face the outer end and can expand radially under the support of the fixed sleeve assembly.

[0014] In some embodiments, the movable sleeve assembly includes:

[0015] A drive nut is threadedly connected to the transmission rod, and a limit part is provided on the drive nut; and

[0016] A spring sleeve, the first end of which is limited and connected to the limiting part, and the second end of which forms the at least two springs.

[0017] In some embodiments, the limiting portion is a plurality of limiting protrusions that are arranged circumferentially along the drive nut and extend axially;

[0018] The first end of the spring sleeve is provided with a plurality of limiting grooves that correspond one-to-one with the plurality of limiting protrusions.

[0019] In some embodiments, the transmission rod is a lead screw, the movable sleeve assembly is threadedly connected to the lead screw, and the outer end of the lead screw is connected to a hook for suspending the hot water equipment.

[0020] In some embodiments, a stop is provided between the lead screw and the hook;

[0021] The fixed sleeve assembly includes a fixed sleeve and a baffle sleeve sleeved on the transmission rod. The fixed sleeve is used to expand the at least two spring pieces, and the baffle sleeve is sandwiched between the fixed sleeve and the stop block.

[0022] In some embodiments, the fixed sleeve has a guide portion at one end facing the at least two spring pieces for guiding the at least two spring pieces to slide toward the fixed sleeve.

[0023] In some embodiments, the end of the retaining sleeve facing the at least two spring tabs is configured as a tapered cylinder, which constitutes the guide portion.

[0024] In some embodiments, the outer wall of the fixing sleeve is configured to abut against the inner wall of the mounting hole for mounting the suspension structure.

[0025] In some embodiments, the lead screw, the hook, and the stop are integrally formed.

[0026] A second aspect of this utility model also provides a hot water device, including a suspension structure for a hot water device as described above.

[0027] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art.

[0028] (1) The suspension structure for hot water equipment provided by this utility model is provided by setting a fixed sleeve assembly and a movable sleeve assembly with a spring piece on the transmission rod. During the process of the transmission rod rotating around its axis in the first direction, the movable sleeve assembly moves towards the fixed sleeve assembly under the transmission action of the transmission rod, so that the spring piece expands outward under the support of the fixed sleeve assembly. When an outward force is applied to the suspension structure, the spring piece is stuck in the wall, and the suspension structure is not easy to loosen, thereby improving the installation stability of the hot water equipment.

[0029] (2) The suspension structure for hot water equipment provided by this utility model can prevent the drive nut from slipping and spinning by connecting the drive nut with the spring sleeve.

[0030] (3) The suspension structure for hot water equipment provided by this utility model has a guide part for guiding the spring to slide towards the fixed sleeve assembly at one end of the fixed sleeve assembly, which is conducive to the outward expansion of the spring.

Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0040] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0041] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] As described in the background section, existing expansion bolts used for suspending electric water heaters cannot be stably fixed to soft walls, thus hindering the stable fixing of the water heater. Based on this, the present invention provides a suspension structure for a hot water device, including a transmission rod, a fixed sleeve assembly, and a movable sleeve assembly. The transmission rod is rotatable about its axis and has an inner end and an outer end. The fixed sleeve assembly is sleeved on the transmission rod near the outer end. The movable sleeve assembly is located on the side of the fixed sleeve assembly facing the inner end and is threadedly connected to the transmission rod. The movable sleeve assembly has at least two spring pieces, the openings of which face the outer end and can expand radially under the support of the fixed sleeve assembly. In the above solution, by setting a fixed sleeve assembly and a movable sleeve assembly with a spring on the transmission rod, the movable sleeve assembly moves towards the fixed sleeve assembly under the transmission action of the transmission rod as the transmission rod rotates around its axis in the first direction. This causes the spring to expand outward under the support of the fixed sleeve assembly. When an outward force is applied to the suspension structure, the spring is stuck in the wall, making the suspension structure less prone to loosening and improving the installation stability of the hot water equipment.

[0043] The preferred technical solution for the suspension structure of hot water equipment provided by this utility model is described below with reference to the accompanying drawings.

[0044] Figure 2 The structure of a suspension structure 100 for an electric water heater according to the present invention is shown; Figure 3 It shows Figure 2 Exploded view of the structure Figure 4 It shows Figure 3 A magnified view of the structure at point A in the middle.

[0045] like Figure 2 and Figure 3 As shown, the suspension structure 100 for a hot water equipment includes a transmission rod 110, a fixed sleeve assembly 140, and a movable sleeve assembly 150. The transmission rod 110 is rotatable about its axis and has an inner end and an outer end. The fixed sleeve assembly 140 is sleeved on the transmission rod 110 near the outer end, and the fixed sleeve assembly 140 and the transmission rod 110 do not move relative to each other in the axial direction. The movable sleeve assembly 150 is located on the side of the fixed sleeve assembly 140 facing the inner end and is threadedly connected to the transmission rod 110. The movable sleeve assembly 150 has at least two spring pieces 153, the openings of which face the outer end and can expand radially under the support of the fixed sleeve assembly 140.

[0046] In the above-described scheme, the suspension structure 100 can be installed in a mounting hole of a mounting base, with the inner end of the transmission rod 110 extending into the mounting hole. The transmission rod 110 has threads and rotates around its axis within the mounting hole. The movable sleeve assembly 150 is threadedly connected to the transmission rod 110, and the movable sleeve assembly 150 can translate axially along the transmission rod 110 under the transmission action of the transmission rod 110. The fixed sleeve assembly 140 cannot move axially relative to the transmission rod 110. It should be noted that this invention does not specifically limit whether the fixed sleeve assembly 140 can rotate circumferentially relative to the transmission rod 110. When the transmission rod 110 is subjected to an external force and rotates around its axis in the first direction, the movable sleeve assembly 150 moves towards the fixed sleeve assembly 140 under the transmission action of the transmission rod 110. This causes the spring piece 153 to expand outward under the support of the fixed sleeve assembly 140, and the suspension structure 100 is fixed by the friction between the spring piece 153 and the wall of the mounting hole. When an outward force is applied to the suspension structure 100, the spring piece 153 is engaged with the wall of the mounting hole, making the suspension structure 100 less prone to loosening and improving the installation stability of the hot water equipment.

[0047] It should be noted that when the suspension structure 100 needs to be removed from the mounting hole, a reverse force can be applied to the transmission rod 110 to make the transmission rod 110 rotate around its axis in a direction opposite to the first direction. Under the transmission action of the transmission rod 110, the moving sleeve assembly 150 moves away from the fixed sleeve assembly 140. After the spring piece 153 loses the support of the fixed sleeve, it will retract inward and not engage with the hole wall of the mounting hole, so that the suspension structure 100 can be removed from the mounting hole.

[0048] It is understood that the first direction is the direction in which the movable sleeve assembly 150 is screwed out. Depending on the direction of the thread, the movable sleeve assembly 150 can be screwed out in a clockwise direction or in a counterclockwise direction. This utility model does not impose any restrictions here.

[0049] The aforementioned mounting base can be a wall, mounting plate, or other structure. It should be noted that the suspension structure provided by this utility model can be used on both rigid and flexible walls.

[0050] In some embodiments, the movable sleeve assembly 150 includes a drive nut 151 and a spring sleeve 152. The drive nut 151 is threadedly connected to the transmission rod 110, and a limiting portion is provided on the drive nut 151. The first end of the spring sleeve 152 is limitedly connected to the limiting portion, and the second end of the spring sleeve 152 forms the at least two springs 153.

[0051] Specifically, the spring sleeve 152 has a long cylindrical structure. The first end of the spring sleeve 152 is connected to the drive nut 151 for limiting. Two to six slits are opened at the second end of the spring sleeve 152 to form multiple spring pieces 153. When the transmission rod 110 is subjected to an external force and rotates around its axis in the first direction, the drive nut 151 drives the spring sleeve 152 to move closer to the fixed sleeve assembly 140 under the transmission action of the transmission rod 110, preventing the drive nut 151 from slipping and spinning freely.

[0052] As an example, refer to Figure 4 As shown, the limiting portion consists of a plurality of limiting protrusions 155 arranged circumferentially along the drive nut 151 and extending approximately axially; wherein, the first end of the spring sleeve 152 is provided with a plurality of limiting grooves 154 corresponding one-to-one with the plurality of limiting protrusions 155. When assembling the suspension structure 100, the spring sleeve 152 can be first sleeved on the transmission rod 110, and then the drive nut 151 can be screwed onto the transmission rod 110 from the inner end of the transmission rod 110 for a certain distance, and then the plurality of limiting grooves 154 of the spring sleeve 152 can be engaged with the limiting protrusions 155 on the drive nut 151.

[0053] It should be noted that the shape and quantity of the limiting protrusion 155 and the limiting groove 154 can be adapted to the model of the suspension structure 100, and this utility model does not impose any restrictions here.

[0054] In some implementations, refer to Figure 2As shown, the transmission rod 110 is a lead screw, and a hook 120 is connected to the outer end of the lead screw. The hook 120 is used to suspend the hot water equipment. The drive nut 151 of the movable sleeve assembly 150 is threadedly connected to the lead screw. When installing the suspension structure 100, a force can be applied to the hook 120 to cause the transmission rod 110 to rotate around its axis. The hook 120 can be configured as an inclined arm, a bent hook, or other shape that cooperates with the bracket of the hot water equipment.

[0055] Furthermore, a stop 130 is provided between the lead screw and the hook 120; wherein, the fixed sleeve assembly 140 includes a fixed sleeve 141 and a baffle 142 sleeved on the transmission rod 110, the fixed sleeve 141 is used to expand the at least two spring pieces 153, and the baffle 142 is sandwiched between the fixed sleeve 141 and the stop 130.

[0056] The function of the aforementioned stop 130 and baffle 142 is to stop the fixed sleeve 141 and prevent the fixed sleeve 141 from axially displacing with the lead screw under the action of the movable sleeve assembly 150, which would be detrimental to the expansion of the spring piece 153.

[0057] In some embodiments, the outer wall of the fixing sleeve 141 is configured to abut against the inner wall of the mounting hole for mounting the suspension structure 100. As can be understood from the above description, the outer diameter of the fixing sleeve 141 matches the inner diameter of the mounting hole, while the outer diameters of the drive nut 151 and the spring sleeve 152 are slightly smaller than the outer diameter of the fixing sleeve 141, so that the drive nut 151 can move the spring sleeve 152 axially under the drive of the lead screw.

[0058] As an example, the lead screw, the hook 120, and the stop 130 are integrally formed. Optionally, the above-mentioned integral structure is made of 304 stainless steel or 316 stainless steel to ensure a firm and reliable installation.

[0059] In some embodiments, the end of the fixing sleeve 141 facing the at least two spring pieces 153 is provided with a guide portion for guiding the at least two spring pieces 153 to slide towards the fixing sleeve 141, preventing the spring pieces 153 from being stuck by the fixing sleeve 141. For example, the end of the fixing sleeve 141 facing the at least two spring pieces 153 is provided as a tapered cylinder 1411, and the tapered cylinder 1411 constitutes the guide portion. Optionally, the cone angle of the tapered cylinder 1411 is approximately in the range of 10° to 20°.

[0060] Furthermore, before the spring piece 153 expands, the front end of the spring piece 153, i.e., the end facing the fixed sleeve 141, can rest on the tapered cylinder 1411. In other words, before the suspension structure 100 is inserted into the mounting hole, the drive nut 151 can be manually tightened so that the spring piece 153 on the spring sleeve 152 and the tapered cylinder 1411 have a certain interference distance in the axial direction. At this time, the spring sleeve 152, the fixed sleeve 141, and the baffle 142 are sandwiched between the drive nut 151 and the stop block 130, and the spring sleeve 152, the fixed sleeve 141, and the baffle 142 cannot move in the axial direction relative to the lead screw. This state is the initial state of the suspension structure 100.

[0061] Specifically, a matching mounting hole is drilled on the mounting base according to the diameter, length, and other dimensions of the suspension structure 100. Then, the suspension structure 100, excluding the hook 120, stop 130, and baffle 142, is hammered into the mounting hole. A force is then applied to the hook 120, causing the lead screw to rotate around its axis in a first direction, causing the drive nut 151, which is threadedly connected to the lead screw, to unscrew outwards. When the drive nut 151 pushes the spring sleeve 152 outwards, multiple springs 153 expand outwards against the tapered cylinder 1411 of the fixed sleeve 141. The greater the outward movement of the spring sleeve 152, the larger the opening diameter of the springs 153, allowing them to fit into the wall of the mounting hole. Since the opening direction of the spring piece 153 is in the same direction as the outward pulling force, when an outward force is applied to the suspension structure 100, the spring piece 153 will be locked in the wall of the mounting hole, making it difficult to pull the mounting structure out of the mounting hole.

[0062] It should be noted that the diameter and length of the suspension structure 100 can be selected according to the water tank capacity of the hot water equipment and the material of the wall to which it is installed. The diameter of the suspension structure 100 is generally between 6 and 12 mm. For hot water equipment with a smaller water tank capacity, a smaller diameter suspension structure 100 can be selected, while for hot water equipment with a larger water tank capacity, a larger diameter suspension structure 100 is required to ensure stability. The length of the suspension structure 100 is usually between 50 and 120 mm. The selection of the length of the suspension structure 100 should take into account the thickness of the wall and the installation location of the hot water equipment. When the wall is thinner, a shorter length of suspension structure 100 can be selected; when the wall is thicker, a longer length of suspension structure 100 is required to ensure that the suspension structure 100 can penetrate the wall and provide sufficient support.

[0063] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
