Description

Technical Field

[0001] The invention belongs to the technical field of umbrellas, and in particular relates to a pulling umbrella. Background Art

[0002] The structure of an umbrella is just like its shape, including an umbrella cover, an umbrella frame and an umbrella handle. The umbrella cover is the outermost part of the umbrella, usually made of waterproof material such as nylon cloth, silk cloth, plastic cloth, etc., which is used to block rain and sun. The umbrella frame is the structure that supports the umbrella cover, which is composed of multiple ribs and sub-ribs connecting them. The ribs are usually made of metal (such as steel, aluminum) or plastic, which enable the umbrella to be folded and opened. The umbrella handle is the part that connects the umbrella cover and the handle, providing structural support for the entire umbrella. These parts work together to enable the umbrella to play its function of sheltering from wind and rain.

[0003] Existing umbrellas generally support the ribs through auxiliary ribs, and then the ribs support the umbrella surface, so they can all be defined as "supporting umbrellas". The support of each umbrella surface requires the cooperation of auxiliary ribs. The existence of auxiliary ribs will increase the overall weight of the umbrella and increase the burden. At the same time, the addition of auxiliary ribs also requires more materials and more complicated processes, which will lead to an increase in production costs. Too many auxiliary ribs will also make the design of the umbrella more complicated and bulky. The deformation and bending of the auxiliary ribs make the umbrella unable to open and close normally, which is also a major reason for the loss of functionality of current umbrellas, reducing the durability and reliability of the umbrella. Summary of the invention

[0004] The purpose of the present invention is to provide an umbrella pulling device, aiming to solve the above problems existing in the prior art.

[0010] In a preferred embodiment of the present invention, a reciprocating motor is installed at the bottom of the umbrella handle and the pull rod is replaced by the reciprocating motor. The umbrella handle is hollow and a pulley is provided on the top of the cavity. A chain is stretched between the output end of the reciprocating motor and the pulley. A sliding groove is provided on the outer circumferential wall of the umbrella handle. The chain is fixedly connected to the umbrella disc through the sliding groove, and the reciprocating motor lifts and lowers the umbrella disc through the chain.

[0016] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0017] Example: like Figure 1-7 As shown, this embodiment provides a pulling umbrella, including an umbrella handle 1 and an umbrella cover 2, on which an umbrella rib 3 for support is stretched, and an umbrella plate 4 is slidably connected to the upper part of the umbrella handle 1, and the umbrella plate 4 is rotatably connected to the end of the umbrella rib 3; A connecting plate is also fixedly mounted on the umbrella handle 1, a lower limit rope 6 is tied between the outer circumferential wall of the connecting plate and the umbrella rib 3, and an upper pull rope 7 is tied between the top of the umbrella handle 1 and the umbrella rib 3; The lower end surface of the umbrella plate 4 is also rotatably connected with a pull rod.

[0018] In a specific application scenario, the pull rod is pulled downward to drive the umbrella plate 4 to slide down synchronously, and the upper end surface of the umbrella ribs 3 and the umbrella cover 2 are pulled by the upper pull rope 7, and the lower end surface of the umbrella cover 2 is pulled by the lower limit rope 6 to realize the overall flipping of the umbrella ribs 3, and then the umbrella cover 2 is driven to expand outward to protect against wind and rain by the "pull plate drive" of the umbrella plate 4; at the same time, the umbrella plate 4 is lifted and driven by the transmission of the reciprocating motor and the chain, so that the umbrella pulling can not only be driven by hand, but also can be electrically controlled, which is more labor-saving and convenient; and in the process of rotating the output end of the reciprocating motor, one end of the upper pull rope 7 is pulled, and then the upper end surface of the umbrella ribs 3 is pulled upward by the "pull rope drive" of the upper pull rope 7, so that the umbrella ribs 3 and the umbrella cover 2 are unfolded. The following is a further description of the umbrella pulling of the present invention in combination with this application scenario.

[0019] Further, refer to Figure 1-7 The upper pull rope 7 is replaced by a metal support rod and both ends are rotatably connected to the top of the umbrella handle 1 and the middle of the umbrella rib 3 respectively.

[0020] In this embodiment, the upper lifting rope 7 is replaced with a support rod. The metal material and fixed length of the upper lifting rope 7 can withstand greater pressure and tension, effectively maintain the stability of the structure, and resist extrusion, bending and twisting in various directions, thereby forming a stable support for the ribs 3 and the umbrella cover 2, and improving the unfolding stability of the umbrella. At the same time, the two ends of the support rod are respectively connected to the top of the umbrella handle 1 and the middle of the ribs 3 to maintain flexibility during the unfolding of the umbrella cover 2, thereby avoiding the unfolding of the umbrella cover 2 due to the upper lifting rope 7. Jam.

[0021] For more details, see Figure 1-7 A handle is integrally provided at the bottom of the pull rod, and a limit groove is provided on the outer circumferential wall of the bottom end of the umbrella handle 1, and the limit groove and the handle are adapted and inserted and limited.

[0022] In this embodiment, in order to prevent the handle from resetting due to the self-weight of the umbrella cover 2 after the user is no longer driving it, resulting in the umbrella cover 2 being unable to remain unfolded stably, a limit groove is provided to match the handle and to be plugged in and limited. As a result, after the pull rod drives the umbrella cover 2 to unfold by pulling downward, it moves downward to the limit groove, and the handle at the bottom end of the pull rod is inserted into the limit groove to form an insertion position, thereby limiting the horizontal height of the pull rod, maintaining the horizontal stability of the pull rod, and thus maintaining the unfolding stability of the umbrella cover 2.

[0023] More preferably, referring to Figure 1-7 The umbrella surface 2 is arranged in a butterfly-wing waveform.

[0024] In this embodiment, the umbrella cover 2 is arranged in a butterfly-wing waveform so that the surface of the umbrella cover 2 is formed in a jumping shape, thereby facilitating the collection and drainage of rainwater, thereby facilitating the discharge of rainwater and helping to reduce the accumulation and retention of rainwater on the umbrella surface.

[0025] More preferably, referring to Figure 1-7 The number of the lower limit rope 6 and the upper pull rope 7 are both even and the number is the same. The lower limit rope 6 and the upper pull rope 7 are staggered and pull the upper end surface and the lower end surface of the umbrella surface 2 in opposite directions respectively.

[0026] In this embodiment, in order to maintain the stable expansion of the umbrella cover 2, the number of lower limit ropes 6 and upper lifting ropes 7 are set to be even and consistent, and the upper end surface and the lower end surface of the umbrella cover 2 are pulled in opposite directions respectively, so as to maintain the stable expansion of the umbrella cover 2 through the balance of tension, increase the bearing pressure of the umbrella cover 2, maintain the stable use of the umbrella cover 2 and prevent the umbrella cover 2 from being over-expanded.

[0027] Furthermore, refer to Figure 1-7 A reciprocating motor is installed at the bottom of the umbrella handle 1 and the pull rod is replaced by the reciprocating motor. The umbrella handle 1 is hollow and a pulley is provided on the top of the cavity. A chain is stretched between the output end of the reciprocating motor and the pulley. A slide groove is opened on the outer circumferential wall of the umbrella handle 1. The chain is fixedly connected with the umbrella disc 4 through the slide groove, and the reciprocating motor lifts and pulls the umbrella disc 4 through the chain.

[0028] In the present embodiment, in order to facilitate the use of the umbrella pulling device, which is more labor-saving and convenient, a reciprocating motor is installed at the bottom of the umbrella handle 1 to replace the pull rod, and a pulley is provided at the top of the cavity of the umbrella handle 1 and a chain is stretched, so that the user can start the reciprocating motor to drive the chain to transmit up and down, and the lifting and lowering drive of the umbrella disc 4 is realized through the fixed connection between the chain and the umbrella disc 4, so that the umbrella pulling device can not only be driven by hand pulling or hand cranking, but also can be electrically controlled; at the same time, in order to make the sliding of the umbrella disc 4 consistent with the transmission of the chain, a sliding groove is opened on the outer circumferential wall of the umbrella handle 1 for the chain and the umbrella disc 4 to maintain a fixed connection and slide synchronously, so as to realize the electric lifting and lowering control of the umbrella disc 4.

[0029] Furthermore, refer to Figure 1-7 The umbrella disc 4 is fixedly connected to the outer circumferential wall of the umbrella handle 1, and the output end of the reciprocating motor is directly wrapped and tied with the upper lifting rope 7. A flange bushing 13 is also fixedly installed on the inner top wall of the umbrella handle 1. The middle part of the flange bushing 13 has an opening for the upper lifting rope 7 to pass through and maintain a sliding connection.

[0030] In the present embodiment, in order to pull the upper end surface of the rib 3 upward by "pulling the rope drive" of the upper lifting rope 7, a flange bushing 13 is fixedly installed on the inner top wall of the umbrella handle 1 for the upper lifting rope 7 to pass through and maintain a sliding connection, thereby reducing the friction during the sliding process of the upper lifting rope 7, making the sliding of the upper lifting rope 7 smoother, and further facilitating the reciprocating motor output end to drive the rib 3 and the umbrella cover 2 to unfold by pulling the upper lifting rope 7.

[0031] More specifically, see Figure 1-7 A hanging ring is also fixedly installed in the middle of the umbrella rib 3, and the two opposing umbrella ribs 3 are tied together by only one lifting rope 7, and the lifting rope 7 passes through the hanging ring and then passes through the flange bushing 13 to be tied to the output end of the reciprocating motor.

[0032] In this embodiment, in order to further reduce the usage of the upper lifting rope 7, a hanging ring is provided in the middle of the umbrella rib 3 for the upper lifting rope 7 to bypass and pass through, so that the upper lifting rope 7 can be first connected to one umbrella rib 3, and then pass through the 13 flange bushing 13 and then through the hanging ring on the other opposite umbrella rib 3, and then pass through the 13 flange bushing 13 and be wrapped and tied with the output end of the reciprocating motor, so that one upper lifting rope 7 can pass through two opposite umbrella ribs 3 at the same time for synchronous pulling, making the unfolding of the umbrella more efficient and reducing the production cost.

[0033] It should be noted that point o in the drawings of the specification is the sliding point of the connecting disk, and the area between o1 and o2 is the sliding range of the connecting disk.

[0034] Working principle: When the umbrella of the present invention needs to be opened, the handle is first pulled downward by hand, and the top of the handle is connected to the umbrella plate 4, thereby driving the umbrella plate 4 to synchronously move and slide downward on the outer circumferential wall of the umbrella handle 1, thereby driving the end of the umbrella rib 3 rotatably connected to the umbrella plate 4 to synchronously slide down, and the middle part of the umbrella rib 3 is simultaneously tied by the lifting rope 7, pulling the upper end surface of the umbrella rib 3 and the umbrella surface 2, so that the umbrella rib 3 does not slide down as a whole, but rotates with the connection point of the umbrella rib 3 and the lifting rope 7 as the fulcrum to realize the overall flipping of the umbrella rib 3, and then the umbrella surface 2 is driven to expand outwards to protect against wind and rain by the "pull plate drive" of the umbrella plate 4; At the same time, the lower limit rope 6 is used to pull the lower end surface of the umbrella 2 to prevent the umbrella 2 from being over-expanded and to maintain the stability of the expansion of the umbrella 2. The top of the handle is connected to the umbrella plate 4 by rotation, so that the handle can be easily switched in angle during the process of pulling down and pushing to avoid being stuck. After the pull rod is pulled down to drive the umbrella 2 to unfold, it moves downward to the limit slot, and the handle at the bottom of the pull rod is inserted into the limit slot to form a plug-in position, thereby limiting the horizontal height of the pull rod and keeping the pull rod horizontal and stable, thereby preventing the handle from being reset due to the self-weight of the umbrella 2 after being driven by the user, resulting in the umbrella 2 being unable to remain unfolded and stable; At the same time, by replacing the upper pull rope 7 with a support rod, the metal material and fixed length of the upper pull rope 7 can withstand greater pressure and tension, effectively maintain the stability of the structure, resist extrusion, bending and twisting in various directions, thereby forming a stable support for the umbrella ribs 3 and the umbrella cover 2; In order to facilitate the use of the umbrella, a reciprocating motor is installed at the bottom of the umbrella handle 1 to replace the pull rod, a pulley is provided at the top of the cavity of the umbrella handle 1 and a chain is stretched, so that the user can start the reciprocating motor to drive the chain to transmit up and down, and the chain and the umbrella plate 4 are fixedly connected to realize the lifting and lowering drive of the umbrella plate 4, so that the umbrella can be pulled not only by hand or hand, but also by electric control, which is more labor-saving and convenient; In order to make the unfolding method of the pull umbrella more diverse, when the umbrella plate 4 is fixedly connected to the outer circumferential wall of the umbrella handle 1, the output end of the reciprocating motor is directly wound and tied with the upper lifting rope 7, and a 13-flange bushing 13 is provided for the upper lifting rope 7 to pass through and maintain a sliding connection, so as to reduce the friction force on the upper lifting rope 7. Therefore, during the rotation of the output end of the reciprocating motor, one end of the upper lifting rope 7 is pulled, and the other end of the upper lifting rope 7 is tied to the umbrella rib 3 through the 13-flange bushing 13, and then the upper end surface of the umbrella rib 3 is pulled upward by the "rope drive" of the upper lifting rope 7, so that the umbrella rib 3 is unfolded, and the umbrella cover 2 is driven to unfold as a whole to protect against wind and rain; At the same time, in the process of driving the upper lifting rope 7 by pulling the reciprocating motor, in order to further reduce the usage of the upper lifting rope 7, a hanging ring is set in the middle of the umbrella rib 3 for the upper lifting rope 7 to bypass and pass through, so that the upper lifting rope 7 can first be connected to one umbrella rib 3, and then pass through the 13 flange bushing 13 and then through the hanging ring on the other opposite umbrella rib 3, and then pass through the 13 flange bushing 13 and be wrapped and tied with the output end of the reciprocating motor, so that one upper lifting rope 7 can pass through two opposite umbrella ribs 3 at the same time for synchronous pulling, making the unfolding of the umbrella more efficient and reducing production costs.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
