Description

Technical Field

[0001] This application relates to the field of fluid transport equipment technology, and in particular to a tarpaulin pump with an adjustable handle. Background Technology

[0002] As a core device for treating water accumulation on tarpaulins, tarpaulin pumps are widely used in outdoor activities, swimming pool canopies, warehousing, and logistics. Their core function is to automatically pump away rainwater accumulated on the tarpaulin surface, preventing damage or deformation due to overload caused by the weight of the water. With the significant increase in the frequency of use and mobility of tarpaulin pumps, the industry's requirements for portability and safety are continuously rising. The handle, as a key component for moving and operating the tarpaulin pump, is crucial; its design directly impacts the user experience and practical value of the equipment.

[0003] To facilitate the movement of tarpaulin pumps, handles are typically installed on them. Most existing tarpaulin pumps use a fixed handle design, which is directly fixed to the top or side of the pump body via welding, forming a rigid structure integrated with the pump body. For ease of daily carrying, the fixed handle usually leaves space at the top of the pump body for gripping.

[0004] Regarding the aforementioned technologies, the fixed handle has a part that protrudes from the pump housing. When the tarpaulin pump is not in use, it is prone to colliding with other objects, which may damage the handle or cause the tarpaulin pump to tip over due to the collision. Utility Model Content

[0005] To avoid the problem of the fixed handle protruding from the pump housing and being easily damaged by collision or causing the shed pump to tip over when it is placed, this application provides a shed pump with an adjustable handle.

[0006] The adjustable handle shed pump provided in this application adopts the following technical solution: An adjustable handle tarpaulin pump includes a pump housing and a housing handle. The housing handle is provided with a plug-in end that engages with the pump housing. The pump housing has a sliding groove that engages with the plug-in end. The plug-in end is provided with an elastic piece and has an elastic groove for the elastic piece to deform and contract. The elastic piece has a limiting ball head for abutting against the pump housing on the side near the pump housing.

[0007] By adopting the above technical solution, the plug end of the housing handle is plugged into the sliding groove of the pump housing, so that the housing handle can be moved and adjusted relative to the pump housing, making it convenient to retract the handle to avoid collision damage and prevent the shed pump from tipping over; when the handle is needed, the housing handle is pulled outward, and the limiting ball head abuts against the outer wall of the pump housing to limit the position of the housing handle and ensure the stability of the housing handle position.

[0008] Optionally, the shed pump in this application further includes a limiting structure for restricting the plug end from disengaging from the sliding groove. The limiting structure includes a limiting protrusion disposed on the inner wall of the sliding groove and a limiting block disposed on the end of the plug end and abutting against the limiting protrusion. The limiting block is provided with a fixing member that is fixedly connected to the handle of the housing.

[0009] By adopting the above technical solution, when the housing handle is pulled outward to the maximum extension length, the limiting block abuts against the limiting protrusion on the inner wall of the sliding groove, which can prevent the plug end from coming out of the sliding groove; the fixing component realizes a stable connection between the limiting block and the plug end, ensuring the long-term reliable operation of the limiting structure.

[0010] Optionally, the fixing member is a fixing screw, the limiting block has a through hole for the fixing screw to pass through, and the plug end has a threaded through hole corresponding to the through hole and threadedly engaged with the fixing screw.

[0011] By adopting the above technical solution, the fixing screw passes through the through hole and the threaded through hole and is locked in place, which can realize the detachable installation of the limit block and the plug end: during installation, the screw is quickly locked, and during disassembly, the screw can be unscrewed to separate the limit block and the plug end, which facilitates the subsequent maintenance and replacement of the sliding groove or the plug end.

[0012] Optionally, the limiting block is provided with positioning posts on both sides of the through hole, and the plug-in end is provided with a mounting through hole for the positioning posts to be inserted.

[0013] By adopting the above technical solution, the positioning post and the mounting through hole can pre-position the limiting block before the fixing screw is installed, ensuring that the through hole of the limiting block is aligned with the threaded through hole of the plug end, and further improving the connection stability between the limiting block and the plug end.

[0014] Optionally, the housing handle is provided with anti-slip stripes on the side facing the pump housing.

[0015] By adopting the above technical solution, the anti-slip stripes can increase the coefficient of friction between the operator's hand and the housing handle. Especially when the hands are wet or when carrying the canvas pump, it can effectively prevent the canvas pump from slipping and falling off, thus improving the safety and stability of holding the pump.

[0016] Optionally, a limiting ring is provided inside the pump housing to abut against the bottom end of the limiting block. When the limiting block abuts against the limiting ring, a lifting gap is formed between the anti-slip stripe and the pump housing.

[0017] By adopting the above technical solution, the limiting ring can limit the housing handle from being pushed too far into the sliding groove: when the limiting block abuts against the limiting ring, the housing handle cannot be pushed in any further. At this time, the lifting gap between the anti-slip stripe and the pump housing can ensure that the hand can be quickly inserted into the lifting gap to pull the housing handle during subsequent use, taking into account both the storage when idle and the convenience when in use.

[0018] Optionally, a support base is installed at the bottom of the pump housing, and an abutment block is provided on the side of the pump housing near the support base. The abutment block and the bottom wall of the pump housing form a sliding groove, and an extension block that inserts into the sliding groove is provided on the side of the support base near the pump housing.

[0019] By adopting the above technical solution, the support base is connected to the pump housing by inserting an extension block into the sliding groove, thereby achieving a fixed connection between the support base and the pump housing. The support base can reduce the probability of the shed pump shifting when placed. At the same time, the structure of the sliding groove facilitates the quick assembly and disassembly of the support base, and the base can be replaced separately when it is worn, reducing maintenance costs.

[0020] Optionally, the sliding groove is an arc-shaped groove, and one end of the sliding groove is open.

[0021] By adopting the above technical solution, the shed pump can rotate the support base in the arc-shaped sliding groove, so that the extension block can be disengaged from the sliding groove. The open end makes it easy to remove the extension block, which simplifies the assembly process of the support base and improves the disassembly efficiency.

[0022] Optionally, the abutting block is provided with a first inclined surface, and the extension block is provided with a second inclined surface adapted to the first inclined surface.

[0023] By adopting the above technical solution, the cooperation between the first inclined surface and the second inclined surface can guide the extension block to be inserted into the sliding groove: when inserted, the two inclined surfaces slide against each other, reducing the jamming area between the extension block and the abutment block. At the same time, the inclined surface cooperation can also form a self-locking effect after assembly, enhancing the connection reliability between the pump housing and the support base.

[0024] Optionally, the support base is provided with a sliding ball, and the support base is provided with a limiting protrusion for limiting the sliding ball.

[0025] By adopting the above technical solution, the sliding ball can convert the sliding friction between the support base and the canvas into rolling friction, making it easier for the canvas pump to move on the canvas, especially suitable for scenarios that require frequent adjustment of the pump body position; the limiting protrusion can limit the displacement of the sliding ball, prevent the ball from falling out of the support base, and ensure that the ball always rolls in the groove formed by the limiting protrusion, thus ensuring the stable movement of the support base.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The adjustment of the housing handle within the pump housing is achieved through the cooperation of the plug end and the sliding groove. When not in use, the handle is pushed into the groove to reduce the protruding part of the housing handle and reduce the collision of the housing handle, effectively alleviating the problem of easy collision of traditional fixed handles. At the same time, the setting of elastic plate and limit ball head can make the handle stable in a suitable position after adjustment, which is convenient for use. 2. The limiting structure prevents the plug end from disengaging from the sliding groove, the positioning post enables quick alignment of the through hole and the threaded through hole, and the anti-slip stripes improve grip safety and enhance the user experience; 3. The design of the sliding groove of the support base, the inclined surface of the extension block and the abutment block, and the sliding ball not only facilitates the disassembly and assembly of the support base and the pump housing, but also facilitates the movement of the canvas pump on the canvas, further improving the practicality and portability of the canvas pump.

[0035] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0036] This application discloses a canopy pump with an adjustable handle.

[0037] Reference Figure 1 and Figure 2 The adjustable handle shed pump includes a pump housing 1 and a housing handle 2. The pump housing 1 has a extraction structure, which is consistent with the structure of existing water pumps and will not be described further in this application. Figure 1 The axis of the pump housing 1 is vertical. An automatic switch 16 for sensing water level is installed in the middle of the pump housing 1, and the automatic switch 16 is electrically connected to the extraction structure of the tarpaulin pump. When the water level exceeds the threshold, the automatic switch 16 transmits a signal to the extraction structure to automatically pump out the water accumulated on the tarpaulin.

[0038] Reference Figure 3 The handle 2 is slidably disposed on the top of the pump housing 1, and has a plug-in end 21 that engages with the pump housing 1. The pump housing 1 has a sliding groove 11 that engages with the plug-in end 21. The plug-in end 21 has an elastic piece 22, and the plug-in end 21 has an elastic groove 23 for the elastic piece 22 to deform and contract. The elastic piece 22 is generally rectangular, and its bottom is integrally formed with the plug-in end 21. Except for the connection point with the elastic piece 22, the plug-in end 21 has through grooves communicating with the elastic groove 23 on its periphery. The side of the elastic piece 22 near the pump housing 1 has a limiting ball head 221 for abutting against the pump housing 1.

[0039] Reference Figure 3 and Figure 4 The plug end 21 has two states in the sliding groove 11: extended and retracted. When the plug end 21 is in the retracted state, the limiting ball head 221 is in the sliding groove 11. At this time, the elastic plate 22 is squeezed and contracted into the elastic groove 23 by the inner wall of the sliding groove 11. When the user pulls the housing handle 2 upward, and after the limiting ball head 221 is disengaged from the sliding groove 11, the elastic plate 22 rotates away from the elastic groove 23 under its elastic reset action, so that the limiting ball head 221 abuts against the top of the pump housing 1. At this time, the plug end 21 is in the extended state.

[0040] Reference Figure 4The shed pump in this embodiment also includes a limiting structure for preventing the plug-in end 21 from dislodging from the sliding groove 11. The limiting structure includes a limiting protrusion 12 disposed on the inner wall of the sliding groove 11 and a limiting block 25 fixedly connected to the end of the plug-in end 21 and used to abut against the limiting protrusion 12. The limiting protrusion 12 is integrally formed with the pump housing 1, and the limiting protrusion 12 is symmetrically arranged along the axis of the sliding groove 11, with two sets of limiting protrusions 12 on both sides of the axis. The limiting block 25 is generally rectangular, with part of the top surface of the limiting block 25 abutting against the bottom of the plug-in end 21, and the remaining part abutting against the limiting protrusion 12. The housing handle 2 abuts against the limiting protrusion 12 through the limiting block 25, so that when the housing handle 2 is pulled up, the risk of the plug-in end 21 dislodging from the sliding groove 11 is reduced, that is, when the limiting block 25 and the limiting protrusion 12 abut against each other, the housing handle 2 is in the maximum extended state.

[0041] Reference Figure 5 The limiting block 25 is provided with a fixing member that is fixedly connected to the handle 2 of the housing. The fixing member is a fixing screw 251. The limiting block 25 has a through hole 252 for the fixing screw 251 to pass through, and the plug end 21 has a threaded through hole 211 that corresponds to the through hole 252 and is threadedly engaged with the fixing screw 251. The fixing screw 251 passes through the through hole 252 and is threadedly locked in the threaded through hole 211, which allows the limiting block 25 and the plug end 21 to be detachably installed.

[0042] The limiting block 25 has positioning posts 253 on both sides of the through hole 252, and the insertion end 21 has a mounting through hole 212 for inserting the positioning posts 253. The positioning posts 253 have guide slopes 2531 to facilitate insertion into the through hole 252. The cooperation between the positioning posts 253 and the mounting through hole 212 can pre-position the limiting block 25 before installing the fixing screw 251, ensuring that the through hole 252 of the limiting block 25 is aligned with the threaded through hole 211 of the insertion end 21.

[0043] Reference Figure 4 The handle 2 of the housing has anti-slip stripes 24 on the side facing the pump housing 1. These stripes are evenly spaced to increase the coefficient of friction between the operator's hand and the handle 2, effectively reducing the risk of the pump slipping off. Inside the pump housing 1, there is a limiting ring 13 that abuts against the bottom of the limiting block 25. When the limiting block 25 abuts against the limiting ring 13, a lifting gap is formed between the anti-slip stripes 24 and the pump housing 1. That is, when the limiting block 25 and the limiting ring 13 are in contact, the handle 2 is in its maximum retracted state. The contact between the limiting block 25 and the limiting ring 13 prevents the insertion end 21 from excessively entering the sliding groove 11. The lifting gap ensures that the operator's hand has space to grip the handle 2 when it is subsequently lifted.

[0044] Reference Figure 1 , Figure 2and Figure 6 A support base 3 is installed at the bottom of the pump housing 1, and the support base 3 is generally disc-shaped. The bottom of the pump housing 1 has an abutment block 14, which forms a sliding groove 15 with an open end with the bottom wall of the pump housing 1. The sliding groove 15 is an arc-shaped groove. The support base 3 has an extension block 31 on the side near the pump housing 1 that inserts into the sliding groove 15. The abutment block 14 has an L-shaped cross-section, and the side of the abutment block 14 facing the extension block 31 has a first inclined surface 141 for guiding insertion into the sliding groove 15. The extension block 31 is generally a combination of a trapezoidal block and a rectangular block, and the extension block 31 has a second inclined surface 311 adapted to the first inclined surface 141. In this embodiment, the bottom of the pump housing 1 has two sets of abutment blocks 14, which are symmetrically arranged along the axis of the pump housing 1. A pull block 34 for fixing a rope is installed on the side of the support base 3 away from the extension block 31, which allows the operator to drag the tarpaulin pump on the tarpaulin.

[0045] When installing the support base 3, the cooperation between the first inclined surface 141 and the second inclined surface 311 can guide the extension block 31 into the sliding groove 15. When disassembling the support base 3, simply move the extension block 31 along the sliding groove 15 to the opening, and remove the extension block 31 from the sliding groove 15 to disassemble the support base 3.

[0046] Reference Figure 7 The bottom of the support base 3 is equipped with three sets of sliding balls 32, and the support base 3 has limiting protrusions 33 for limiting the sliding balls 32. The limiting protrusions 33 are arranged in three equal parts circumferentially along the axis of the sliding balls 32, and the three sets of limiting protrusions 33 form a sliding groove 331 that restricts the sliding balls 32 from disengaging from the support base 3. The sliding balls 32 can convert the sliding friction between the support base 3 and the fabric into rolling friction, making it easier for the fabric pump to move on the fabric.

[0047] The implementation principle of an adjustable handle tarpaulin pump according to an embodiment of this application is as follows: When the housing handle 2 needs to protrude from the pump housing 1, the limiting ball head 221 abuts against the outer wall of the pump housing 1, stabilizing the position of the housing handle 2. At this time, the tarpaulin pump can be moved by pulling the housing handle 2. When the housing handle 2 needs to retract into the pump housing 1, pressing the housing handle 2 causes the elastic piece 22 to be squeezed by the inner wall of the sliding groove 11, deforming and retracting into the elastic groove 23. When the insertion end 21 moves along the sliding groove 11 to abut against the abutting ring, the anti-slip stripe 24 of the housing handle 2 forms a lifting gap with the top of the pump housing 1. At this time, the tarpaulin pump is placed on the tarpaulin or in an idle state. The lifting gap provides space for the operator to hold the housing handle 2 when moving the tarpaulin pump next time.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
