Description

Technical Field

[0001] This invention relates to the field of garden irrigation technology, specifically to a novel automatic pipe retractor with a deceleration structure. Background Technology

[0002] Watering green plants typically involves using tap water pressure to deliver water through a pipe to the area needing irrigation. This water is then connected to a sprinkler system to irrigate crops, flowers, trees, vegetables, and orchards. The water source is usually located in a relatively fixed location, such as a faucet mounted on a wall or a valve on the lawn. After irrigation, the exposed pipes are prone to aging, cracking from being run over, or coming into contact with sharp objects. Furthermore, the pipe length is limited due to the large area being irrigated, and the need to frequently move the pipes to different locations makes dragging and retracting them inconvenient. Therefore, a device for storing and storing water pipes is needed.

[0003] There are many products available for garden sprinkler irrigation, and water hose carts come in various types, including push-type, hand-cranked, and foot-operated, all of which can meet certain usage requirements. However, due to the large number of areas requiring irrigation and the frequent relocation of these products, carrying them can be inconvenient. Some outdoor products cannot be secured, and the support frame may shift when the hose is pulled out, causing inconvenience to consumers. Therefore, these existing solutions do not meet current needs. To address this, we have proposed a new type of automatic hose retractor with a deceleration structure. Summary of the Invention

[0004] This invention provides a novel automatic hose reel with a deceleration structure, which ensures that the water hose can be neatly wound around it, and the orienter ensures that the water hose enters and exits in a straight line, thus avoiding tangling.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1 aims to address the inconvenience of carrying products due to the large number of locations requiring irrigation and frequent relocation, as well as the issue that some outdoor products cannot be securely fixed, causing the support frame to shift when the water hose is pulled out, resulting in inconvenience for consumers. Please refer to [link / reference]. Figures 1-6An automatic pipe winding device with a novel deceleration structure includes a wheel 110, a support frame 111, and a handrail 112. The handrail 112 is mounted on the support frame 111. The wheel 110 is located inside the support frame 111 and is used to wind up the water pipe. There are two wheels 110, and a fixing frame 113 is installed between the two wheels 110. The fixing frame 113 and the wheel 110 are both provided with fixing grooves 114. A pop rivet 115 for fixing the fixing frame 113 is inserted into the fixing groove 114. A base 116 is installed on the outside of the wheel 110. A pipe winding assembly 130 is provided on the support frame 111 and is located on the upper side of the wheel 110. A water inlet assembly 150 for water pipe inlet is provided on the side of the support frame 111.

[0028] A crank connecting rod 120 is rotatably inserted into the base 116 and the support frame 111. A crank connecting plate 121 is fitted over the crank connecting rod 120. A small crank glove 122 is inserted into the other end of the crank connecting plate 121. A small crank shaft 123 is inserted into the small crank glove 122. A crank nut 124 is threaded onto the external thread of the crank connecting rod 120. A crank bushing 125 is threaded onto the end of the small crank shaft 123. A groove 126 is provided on the side of the support frame 111. A wrench 127 is provided in the groove 126. One end of the wrench 127 is installed in the groove 126 through a pin 128. A pull rod spring 129 is provided in the groove 126. One end of the pull rod spring 129 is connected to the groove 126, and the other end of the pull rod spring 129 is connected to the wrench 127.

[0029] The tube winding assembly 130 includes a tube winding bracket 131 mounted on a support frame 111. Two tube winding brackets 131 are provided. A support rod 132 and a tube winding rod 133 are movably installed between the two tube winding brackets 131. The support rod 132 is located on the upper side of the tube winding rod 133. A tube winding wheel 134 is threaded onto the external side of the tube winding rod 133. An oriented device 135 is inserted into the tube winding wheel 134. A tube winding wheel buckle 156 is installed on the outside of the oriented device 135.

[0030] The user first turns on the water inlet assembly 150, connects the water source, and ensures that the water pipe can supply water normally. The automatic hose reel is then placed in the area requiring irrigation, ensuring that the support frame 111 is firmly placed on the ground. The structure of the base 116 and the support frame 111 ensures the stability of the device.

[0031] The user holds the handle 112 and, through the crank connecting rod 120 and the crank assembly crank connecting plate 121, small crank glove 122, small crank shaft 123, crank nut 124, and crank shaft sleeve 125, manually or automatically rotates the wheel 110 to wind the water pipe onto the wheel 110. The crank connecting rod 120 is fitted with a crank connecting plate 121, and the other end is connected to the small crank glove 122 and small crank shaft 123, which are fixed and adjusted by the threaded crank nut 124 and crank shaft sleeve 125. The user then manually or automatically rotates the wheel 110 through the crank connecting rod 120 and the crank assembly to pull the water pipe off the wheel 110. The water pipe enters the winding assembly 130 through the water inlet assembly 150. After entering through the water inlet assembly 150, the water pipe passes through the guide groove of the orienter 135 to ensure that it enters the winding wheel 134 in a straight line. The function of the orienter 135 is to prevent the water pipe from getting tangled or knotted on the pipe winding wheel 134.

[0032] When the user rotates the wheel 110, the winding wheel 134 also rotates. The grooves 126 or protrusions on the winding wheel 134 ensure that the water pipe is neatly wound around it. The winding wheel 134 is threaded onto the winding rod 133, ensuring stability and preventing it from slipping during rotation. The support rod 132 provides vertical support, ensuring the stability of the winding rod 133. The position and height of the support rod 132 can be adjusted according to the thickness of the water pipe to accommodate different irrigation needs. The winding wheel 134 is fastened to the outside of the orienter 135 for further securing the water pipe. The clamping device can be adjusted to ensure that the water pipe does not loosen or slip during winding.

[0033] After the user completes the irrigation task, the hand crank connecting rod 120 and the hand crank assembly are used to rotate the reel 110 in the opposite direction, winding the water hose back onto the reel 110. The hose winding wheel 134 continues to rotate, neatly winding the water hose onto the reel 110. The hose winding wheel 134 and the guide 135 ensure that the water hose does not become tangled or knotted during winding. These components work together to ensure that the water hose can be neatly wound onto the reel 110.

[0034] During the hose reel winding process, the user can adjust the position and status of the hose winding assembly 130 using a wrench 127 and a pull rod spring 129. One end of the wrench 127 is mounted in a groove 126 via a pin 128. A pull rod spring 129 is installed in the groove 126, with one end connected to the groove 126 and the other end connected to the wrench 127. These adjustments ensure the stability of the hose winding assembly 130 during the reel winding process and prevent the support from shifting.

[0035] In this embodiment: the water pipe is wound and fixed by the winding wheel 134 and the orienter 135. The groove 126 or protrusion design on the winding wheel 134 ensures that the water pipe can be neatly wound on it. The orienter 135 ensures that the water pipe enters and exits in a straight line and avoids tangling. The water pipe can be wound manually or automatically by means of components such as the crank connecting rod 120, crank connecting plate 121, small crank sleeve 122, small crank shaft 123, crank nut 124 and crank shaft sleeve 125. This allows the user to easily rotate the wheel 110 to pull the water pipe out or roll it back from the wheel 110. The operation is simple. The support frame 111 has a groove 126 on the side. The groove 126 is provided with a wrench 127 and a pull rod spring 129. The user can use these components to adjust the position and state of the winding assembly 130 to ensure the stability of the winding assembly 130 during the winding process and prevent the support from shifting.

[0036] Example 2 aims to address the potential issues of insufficient mobility or instability in the pipe winding assembly 130 during pipe winding. This example is an improvement upon Example 1. For details, please refer to [link to example]. Figures 1-6 A movable sleeve 136 is fitted over the support rod 132. Limiting plates 137 are installed at both ends of the movable sleeve 136. A limiting groove 138 corresponding to the winding rod 133 is opened at the bottom of the limiting plate 137. The movable sleeve 136 with the limiting groove 138 is located outside the winding rod 133. A fixing plate 139 is installed on the side of the winding bracket 131. A fixing rod 140 is installed on the fixing plate 139, and the fixing rod 140 is rotatably inserted into the support rod 132 and the winding rod 133.

[0037] The support frame 111 includes a front support 141, a rear support 142, a left support 143, and a right support 144. The right support 144 is installed on one side of the rear support 142, and the left support 143 is installed on the other side of the rear support 142. Lower supports 149 are sleeved at both ends of the rear support 142. Both the right support 144 and the left support 143 have first insertion slots 145. The top of the front support 141 is inserted into the first insertion slot 145, and the lower support 149 has a second insertion slot 146. The bottom ends of both the right support 144 and the left support 143 are inserted into the second insertion slots 146. It can be placed horizontally on lawns, has a low center of gravity, good stability, and will not slip when the water hose is pulled out during normal use. It remains relatively stable on any uneven ground.

[0038] By setting up a front support 141, a rear support 142, a left support 143, a right support 144, and a lower support, a more stable support frame is formed. The right support 144 and the left support 143 are provided with a first insertion slot 145. The top of the front support 141 is inserted into the first insertion slot 145. The lower support is provided with a second insertion slot 146. The bottom of the right support 144 and the left support 143 are both inserted into the second insertion slot 146. This multi-support design allows the device to be placed horizontally on the lawn with a low center of gravity and good stability. The product will not slip when the water pipe is pulled out.

[0039] In this embodiment, by adding a movable sleeve 136, a limiting plate 137, and a fixing plate 139 to the winding pipe assembly 130, the movable sleeve 136 is equipped with limiting plates 137 at both ends, and the bottom of the limiting plate 137 is provided with a limiting groove 138 corresponding to the winding pipe rod 133. The movable sleeve 136 of the limiting groove 138 is located on the outside of the winding pipe rod 133. The side of the winding pipe support 131 is equipped with a fixing plate 139, and a fixing rod 140 is installed on the fixing plate 139. The fixing rod 140 is rotatably inserted into the support rod 132 and the winding pipe rod 133, which not only increases the mobility of the winding pipe assembly 130, but also improves its stability, ensuring that the water pipe will not loosen or slip during the winding process.

[0040] Example 3 aims to address the potential problems of inconvenient pipe connections and insufficient sealing, which can lead to leaks during pipe winding and unwinding. This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 1-6 The water inlet assembly 150 includes a water inlet groove 151 formed on the left bracket 143. A bent pipe 152 is inserted into the water inlet groove 151. An inner clamping connector 153 is installed at the end of the bent pipe 152. A connector plastic coating 154 is connected to the end of the inner clamping connector 153. A water-stop ring 155 is installed between the inner clamping connector 153 and the connector plastic coating 154. The left bracket 143 and the right bracket 144 have mounting grooves 147 corresponding to the handrail 112. The bottom end of the handrail 112 is inserted into the mounting groove 147. A pipe plug 148 is installed in the mounting groove 147. The left bracket 143 and the right bracket 144 have mounting grooves 147 corresponding to the handrail 112. The bottom end of the handrail 112 is inserted into the mounting groove 147. A tube plug 148 is installed in the mounting groove 147 to ensure the fixed stability of the handrail 112. With the cooperation of the mounting groove 147 and the tube plug 148, the handrail 112 is more stable during use, and the user feels more comfortable and safe when holding the handrail 112.

[0041] In this embodiment: the water inlet assembly 150 includes a water inlet groove 151 opened on the left bracket 143, a bent pipe 152 is inserted into the water inlet groove 151, an inner clamping connector 153 is installed at the end of the bent pipe 152, a connector plastic coating 154 is connected to the end of the inner clamping connector 153, and a water stop ring 155 is installed between the inner clamping connector 153 and the connector plastic coating 154, which makes the connection of the water pipe more convenient. The installation of the water stop ring 155 improves the sealing of the connection and prevents water leakage during the winding and unfolding of the water pipe.
