Description

Technical Field

[0001] This utility model belongs to the field of outdoor equipment technology, specifically a sunshade opening and closing mechanism. Background Technology

[0002] With the rapid development of the tourism industry, pole umbrellas or hanging umbrellas, as outdoor leisure tools, are widely used in squares, beaches, parks and courtyards, providing people with comfortable leisure and shade spaces. Sun umbrellas are a type of sun protection product widely used outdoors in daily life. They are mainly composed of umbrella fabric, umbrella cap (some sun umbrellas do not have an umbrella cap), umbrella frame, umbrella pole and umbrella base. The umbrella fabric of traditional sun umbrellas is made by sewing together several small areas of sunshade fabric and covering and fixing them to the surface of the umbrella frame, so that it can be folded and stored with the umbrella frame.

[0003] Existing sun umbrella opening and closing mechanisms generally use umbrella cords or levers to drive the umbrella's related canopies to open and close. These are all continuous opening and closing mechanisms, which lack good restraint when closed, making them easy to be accidentally opened, affecting carrying and transportation. Moreover, after opening, an independent positioning mechanism is required to ensure its stability. However, in practice, this positioning mechanism is mostly implemented in the form of a slot and a bead, which is relatively simple. If the umbrella frame is subjected to force, it may break due to the obstruction of this positioning mechanism.

[0004] Therefore, it is necessary to develop a new type of opening and closing mechanism for sun umbrellas to address the shortcomings of existing technologies. Utility Model Content

[0005] To address the problems mentioned in the background section, this utility model provides a sunshade opening and closing mechanism with the advantages of automatic positioning and anti-collision protection.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sunshade umbrella opening and closing mechanism, including an umbrella column, a plurality of evenly distributed main support rods hinged to the upper end of the umbrella column, a positioning component located below the main support rods on the outside of the umbrella column, a plurality of evenly distributed secondary support rods hinged to the outside of the positioning component, the other end of the secondary support rods hinged to the middle of the main support rods near the umbrella column, and a handle fixedly connected to the bottom of the umbrella column; The positioning component includes a linkage component hinged to the end of the auxiliary support rod away from the main support rod. The bottom of the linkage component is connected to a control component. The control component is slidably sleeved on the outside of the umbrella column. The linkage component is also provided with an adjustment component, which is slidably snapped onto the outside of the umbrella column. The control assembly consists of a control sleeve, a buffer spring, and two locking structures embedded in the surface of the umbrella column. The control sleeve is movably fitted onto the outside of the umbrella column, and the buffer spring is fitted onto the outside of the umbrella column and connected between the control sleeve and the linkage assembly. The control sleeve is kept relatively stationary with the umbrella column through the locking structures.

[0007] Furthermore, the control sleeve has an easy-grip structure, and a groove is provided inside the control sleeve. The outer end of the locking structure extends to the outside of the umbrella column and is locked inside the groove on the control sleeve.

[0008] Furthermore, the locking structure includes a slot formed on the side of the umbrella column. The end of the slot near the axis of the umbrella column is a cylindrical cavity structure, and the end of the slot away from the axis of the umbrella column is a spherical cavity structure. The side of the spherical cavity structure away from the axis of the umbrella column extends to the outside of the umbrella column, and the center of the spherical cavity structure is located inside the umbrella column.

[0009] Furthermore, a retaining bead is movably installed inside the slot. The side of the retaining bead away from the umbrella column axis extends to the outside of the umbrella column through the slot and engages with the groove on the control sleeve. A positioning spring is also provided inside the slot to support and connect the retaining bead to the side near the umbrella column axis.

[0010] Furthermore, several of the auxiliary support rods and main support rods correspond one-to-one. The top of several of the main support rods is sewn with umbrella fabric. When unfolded, the umbrella fabric has a conical structure. The top of the umbrella fabric is fixed and sealed to the upper end of the umbrella column, and the lower end of the umbrella fabric is sewn to the surface of the main support rod.

[0011] Furthermore, the linkage assembly includes a linkage ring sleeved on the outside of the umbrella column and connected to the top of the buffer spring. The top of the linkage ring is connected to a linkage sleeve sleeved on the outside of the umbrella column, and the auxiliary support rod is hinged to the outer surface of the linkage sleeve.

[0012] Furthermore, the inner diameter of the linkage sleeve is larger than the outer circumferential diameter of the umbrella column, and the adjustment component is connected to the upper and lower ends of the linkage ring; The adjustment assembly consists of a control sleeve and an adjustment sleeve. The control sleeve is fixedly connected to the bottom of the linkage ring and sleeved on the outside of the buffer spring. The adjustment sleeve is fixedly connected to the top of the linkage ring and sleeved between the umbrella column and the linkage sleeve. The linkage sleeve is threaded onto the outside of the adjustment sleeve.

[0013] Furthermore, the outer surface of the umbrella column is provided with several evenly distributed positioning grooves. The inner side of the positioning grooves is slidably engaged with two positioning sliders, one above the other. The outer side of the umbrella column is movably sleeved with a positioning linkage ring located outside the upper positioning sliders. The outer side of the positioning sliders passes through the positioning grooves and extends to the outer side of the umbrella column and is fixedly connected to the inner side of the positioning linkage ring. The positioning linkage ring is movably sleeved inside the linkage ring. The lower positioning slider is fixedly connected to the inner side of the control sleeve.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: Due to the design of the control components, this invention, in conjunction with the control sleeve and the buffer spring, can control several auxiliary support rods to move upward through the linkage and adjustment components. Simultaneously, under the constraints of the umbrella column and the main support rod, the upward-moving auxiliary support rods can support the corresponding main support rods, thereby supporting the umbrella fabric. Under the constraint of the tapered umbrella fabric, the main support rod and auxiliary support rods ultimately reach the maximum opening angle. Thus, under the constraint of the locking structure on the control sleeve, the elastic restoring force of the buffer spring can achieve a cushioning effect on the umbrella fabric after opening. Moreover, after storage, there is no need for the complicated operation of rolling up the umbrella fabric and fixing it with straps.

[0015] Due to the adjustment component and the linkage component, the linkage sleeve can be adjusted up and down by rotating the control sleeve and adjustment sleeve. This changes the distance between the linkage sleeve and the control sleeve. When the control sleeve is connected to the corresponding locking structure after the umbrella is opened to the maximum angle, the elastic restoring force of the buffer spring is changed. This makes the umbrella suitable for different impact resistance environments, which not only improves the service life of the umbrella but also provides a certain degree of safety protection.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1 to 5 As shown, this utility model provides a sunshade umbrella opening and closing mechanism, including an umbrella column 1, with a plurality of evenly distributed main support rods 2 hinged to the upper end of the umbrella column 1, a positioning component 3 located below the main support rods 2 on the outside of the umbrella column 1, a plurality of evenly distributed secondary support rods 4 hinged to the outside of the positioning component 3, the other end of the secondary support rods 4 being hinged to the middle of the main support rods 2 on the side near the umbrella column 1, and a handle 5 being fixedly connected to the bottom of the umbrella column 1. The positioning component 3 includes a linkage component 31 hinged to the end of the auxiliary support rod 4 away from the main support rod 2. The bottom of the linkage component 31 is connected to a control component 32. The control component 32 is slidably sleeved on the outside of the umbrella column 1. The linkage component 31 is also provided with an adjustment component 33, which is slidably snapped onto the outside of the umbrella column 1. The control component 32 consists of a control sleeve 321, a buffer spring 322, and two locking structures embedded in the surface of the umbrella column 1. The control sleeve 321 is movably sleeved on the outside of the umbrella column 1, and the buffer spring 322 is sleeved on the outside of the umbrella column 1 and connected between the control sleeve 321 and the linkage component 31. The control sleeve 321 is relatively stationary with the umbrella column 1 through the locking structures. Due to the configuration of the control component 32, with the cooperation of the control sleeve 321 and the buffer spring 322, several auxiliary support rods 4 can be controlled to move upward through the linkage component 31 and the adjustment component 33. At the same time, under the constraint of the umbrella column 1 and the main support rod 2, the upward-moving auxiliary support rods 4 can support the corresponding main support rod 2, thereby opening the umbrella fabric. Under the constraint of the conical umbrella fabric, the main support rod 2 and the auxiliary support rods 4 can finally reach the maximum opening angle. Thus, under the constraint of the locking structure on the control sleeve 321, the elastic restoring force of the buffer spring 322 can achieve the effect of buffering the umbrella fabric after opening. Moreover, after storage, there is no need to perform the complicated operation of rolling up the umbrella fabric and fixing it with straps.

[0020] Among them, the control sleeve 321 is an easy-grip structure. The control sleeve 321 has a groove inside. The outer end of the locking structure extends to the outside of the umbrella column 1 and is locked inside the groove on the control sleeve 321.

[0021] The locking structure includes a slot 323 opened on the side of the umbrella column 1. The end of the slot 323 near the axis of the umbrella column 1 is a cylindrical cavity structure, and the end of the slot 323 away from the axis of the umbrella column 1 is a spherical cavity structure. The side of the spherical cavity structure away from the axis of the umbrella column 1 extends to the outside of the umbrella column 1, and the center of the spherical cavity structure is located inside the umbrella column 1. Due to the spherical cavity, the disengagement of the retaining ball 324 can be restricted. At the same time, with the cooperation of the cylindrical cavity, the retaining ball 324 can slide radially to disengage from the groove on the inner side of the control sleeve 321, while compressing the positioning spring 325.

[0022] The slot 323 contains a movable bead 324. The side of the bead 324 away from the axis of the umbrella column 1 extends through the slot 323 to the outside of the umbrella column 1 and is engaged in the groove on the control sleeve 321. The slot 323 also contains a positioning spring 325 that abuts against the side of the bead 324 that is close to the axis of the umbrella column 1. Due to the elastic restoring force of the positioning spring 325, the retaining ball 324 can further compress the positioning spring 325 to disengage from the control sleeve 321. At the same time, under the elastic restoring force of the retaining ball 324, the retaining ball 324 can automatically and timely engage in the inner groove of the control sleeve 321.

[0023] Among them, several auxiliary support rods 4 correspond one-to-one with the main support rods 2. The top of several main support rods 2 is sewn with umbrella cloth. When the umbrella cloth is unfolded, it has a conical structure. The top of the umbrella cloth is fixed and sealed to the upper end of the umbrella column 1, and the lower end of the umbrella cloth is sewn to the surface of the main support rod 2.

[0024] The linkage component 31 includes a linkage ring 311 that is sleeved on the outside of the umbrella column 1 and connected to the top of the buffer spring 322. The top of the linkage ring 311 is connected to a linkage sleeve 312 that is sleeved on the outside of the umbrella column 1. The auxiliary support rod 4 is hinged to the outer surface of the linkage sleeve 312.

[0025] Among them, the inner diameter of the linkage sleeve 312 is larger than the outer diameter of the umbrella column 1, and the adjustment component 33 is connected to the upper and lower ends of the linkage ring 311. The adjustment assembly 33 consists of an operating sleeve 331 and an adjusting sleeve 332. The operating sleeve 331 is fixedly connected to the bottom of the linkage ring 311 and is sleeved on the outside of the buffer spring 322. The adjusting sleeve 332 is fixedly connected to the top of the linkage ring 311 and is sleeved between the umbrella column 1 and the linkage sleeve 312. The linkage sleeve 312 is threaded onto the outside of the adjusting sleeve 332. Due to the setting of the adjustment component 33, in cooperation with the linkage component 31, and due to the limiting effect of the positioning slide groove 313 and the positioning slider 314 on the linkage ring 311, the rotation of the operating sleeve 331 and the adjustment sleeve 332 can achieve the purpose of adjusting the up and down movement of the linkage sleeve 312, thereby changing the distance between the linkage sleeve 312 and the control sleeve 321. As a result, when the control sleeve 321 is connected to the corresponding locking structure after the maximum opening angle, the elastic restoring force of the buffer spring 322 is changed, so that it can be used in environments with different impact resistance requirements, which not only improves the service life of the umbrella, but also has a certain safety protection performance.

[0026] The umbrella column 1 has several evenly distributed positioning grooves 313 on its outer surface. The positioning grooves 313 are slidably engaged with two upper and lower positioning sliders 314. The umbrella column 1 is movably sleeved with a positioning linkage ring 315 located outside the upper positioning sliders 314. The outer side of the positioning sliders 314 passes through the positioning grooves 313 and extends to the outside of the umbrella column 1 and is fixedly connected to the inner side of the positioning linkage ring 315. The positioning linkage ring 315 is movably sleeved inside the linkage ring 311. The lower positioning sliders 314 are fixedly connected to the inner side of the control sleeve 321. The positioning slider 314 can further improve the stability of the linkage component 31 and the control sleeve 321 when sliding, avoid the linkage component 31 and the auxiliary support rod 4 from shaking randomly during non-rotation adjustment, and limit the rotation of the control sleeve 321 to ensure that the groove inside the control sleeve 321 that slides up and down can be accurately engaged with the outside of the ball 324.

[0027] Working principle and usage process of this utility model: After holding the handle 5 with one hand, hold the control sleeve 321 with the other hand and control it to slide up and down along the surface of the umbrella column 1; When opening is required: While gripping the handle 5, control the control sleeve 321 to move upward. Under the restriction of the operating sleeve 331, the linkage ring 311 is pushed upward by the buffer spring 322, and several auxiliary support rods 4 are pushed upward by the linkage sleeve 312. Then, under the restriction of the upper end of the umbrella column 1 on the upper end of the main support rod 2, the rising auxiliary support rods 4 gradually support the corresponding main support rod 2. Finally, under the restriction of the umbrella cloth sewn on the outside of the main support rod 2, the main support rod 2 is supported by the auxiliary support rods 4 to the maximum opening angle. Then, continue to push the control sleeve 321 upward to further compress the buffer spring 322 to increase its elastic restoring force until the control sleeve 321 moves to the outside of the upper slot 323. Under the action of the elastic restoring force of the corresponding positioning spring 325, the locking ball 324 is locked into the slot on the inside of the control sleeve 321. When the top of the umbrella is accidentally hit, the main support rod 2 and the auxiliary support rod 4 can swing downward under the elastic restoring force of the buffer spring 322 to obtain cushioning. When it needs to be retracted: reverse the operation to move the control sleeve 321 to the lower end of the umbrella column 1 until the main support rod 2 and the auxiliary support rod 4 are pulled to be parallel to the umbrella column 1. At this time, the umbrella column 1, the main support rod 2 and the auxiliary support rod 4 are in contact with each other. Continue to pull the control sleeve 321 downwards so that the buffer spring 322 is further stretched under the restriction of the main support rod 2 and the auxiliary support rod 4, and its elastic restoring force is increased until the control sleeve 321 moves to the outside of the lower slot 323. Under the action of the elastic restoring force of the corresponding positioning spring 325, the locking ball 324 is locked into the slot on the inside of the control sleeve 321. At this time, the control sleeve 321 is located at the lower end of the main support rod 2. When the umbrella is moved, the main support pole 2, the secondary support pole 4 and the umbrella canopy will not open accidentally due to inertia or wind resistance, which greatly improves storage and portability. When it is necessary to control the support of the umbrella fabric after it is opened to the maximum angle, so as to resist impacts of different intensities, the main support rod 2, the auxiliary support rod 4 and the umbrella fabric are cushioned, while avoiding the impact from the user's body after the main support rod 2, the auxiliary support rod 4 and the umbrella fabric are deformed. Specifically, the control sleeve 331 is rotated so that, with the cooperation of the positioning slide groove 313, the positioning slider 314 and the positioning linkage ring 315, the linkage ring 311 is driven to rotate, which in turn drives the adjustment sleeve 332 to rotate. The rotation of the adjustment sleeve 332 can drive the linkage sleeve 312 to move up and down along the outside of the adjustment sleeve 332 under the restriction of the main support rod 2 and the auxiliary support rod 4, so as to change the distance between the linkage sleeve 312 and the control sleeve 321, and ensure that the elastic restoring force of the buffer spring 322 changes after the maximum opening angle.
