Description

Technical Field

[0001] This invention relates to the technical field of umbrellas, and particularly to a telescopic umbrella handle. Background Technology

[0002] A folding umbrella is a portable umbrella that uses a foldable design for its ribs and canopy. Based on the number of folds, there are two-section folding umbrellas, three-section folding umbrellas, etc. The folded size is small and easy to carry, making it suitable for daily travel. In order to accommodate even smaller storage sizes, the handle is usually shortened to further reduce the length of the folding umbrella. However, the short handle cannot be fully supported by the hand, which can easily cause hand fatigue after prolonged use. Summary of the Invention

[0003] The purpose of this utility model is to provide a telescopic umbrella handle. The technical problem to be solved is to provide a telescopic umbrella handle that is convenient for hand grip when extended and convenient for umbrella storage when retracted.

[0004] To achieve the above objectives, the solution of this utility model is: a telescopic umbrella handle, comprising an umbrella handle body, a sleeve, and a handle base; The umbrella handle body is used to fix it to the end of the umbrella shaft; A sleeve, fitted over the main body of the umbrella handle; The handle is rotatably connected to the end of the sleeve opposite the umbrella shaft; One of the sleeve and the handle seat forms a helical connection with the umbrella handle body so that the umbrella handle body can extend or retract from the sleeve toward the umbrella shaft by means of its relative rotation with respect to the umbrella handle body. The other of the sleeve and handle seat forms a sliding connection with the umbrella handle body along the direction of extension and retraction of the umbrella handle body from the sleeve, and forms a circumferential engagement with the umbrella handle body to drive the umbrella handle body to rotate.

[0005] Furthermore, the sleeve is spirally connected to the umbrella handle body, and the handle seat is axially slidably connected to the umbrella handle body and circumferentially engaged, so that after the handle seat rotates relative to the sleeve, it can drive the umbrella handle body to rotate circumferentially.

[0006] Furthermore, a guide is formed on the handle base extending towards the umbrella handle body, and a sliding groove is formed on the guide. The sliding groove extends axially, and a pin protrudes from the outer side wall of the umbrella handle body. The pin is inserted into and slidably engaged in the sliding groove, so that the umbrella handle body is slidably set on the handle base and circumferentially engaged with the handle base.

[0007] Furthermore, the inner wall of the sleeve has a spiral groove extending circumferentially, the groove radially passes through the guide, the pin passes through the groove, and the end of the pin is inserted into the spiral groove, so that the umbrella handle body is spirally connected to the sleeve.

[0008] Furthermore, the two ends of the slide extend circumferentially to form limiting grooves. The two limiting grooves extend in opposite directions so that when the umbrella handle body is extended to its longest or retracted to its smallest position, the limiting grooves are used to restrict the axial movement of the pin.

[0009] Furthermore, the handle is shaped like a ping-pong ball, and its outer edge extends toward the sleeve to form an irregularly wavy annular baffle wall that surrounds the outer perimeter of the sleeve.

[0010] Furthermore, the sleeve and the shank are axially engaged, allowing the sleeve and the shank to rotate relative to each other only in the circumferential direction.

[0011] Furthermore, the sleeve is axially slidably connected to the umbrella handle body and circumferentially engaged, and the handle seat is helically connected to the umbrella handle body so that after the handle seat rotates relative to the umbrella handle body, it can drive the umbrella handle body to extend or retract from the sleeve in the direction of the umbrella shaft.

[0012] Furthermore, the pins can be detachably installed on the umbrella handle body.

[0013] The beneficial effects of the present invention after adopting the above solution are as follows: one of the sleeve and the handle base forms a spiral connection with the umbrella handle body, so that the umbrella handle body can be extended or retracted from the sleeve in the direction of the umbrella shaft by the relative rotation of the sleeve and the umbrella handle body; the other of the sleeve and the handle base forms a sliding connection with the umbrella handle body along the direction of the umbrella handle body extending and retracting from the sleeve, and forms a circumferential engagement with the umbrella handle body, so that by driving the handle base to rotate relative to the sleeve, the umbrella handle body can be extended from the sleeve to lengthen the umbrella handle and make it easier to hold, or by driving the handle base to rotate in the opposite direction relative to the sleeve, the umbrella handle body can be retracted from the sleeve to shorten the length of the umbrella handle and make it easier to store.

[0019] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", "middle", "top", "bottom", "inner", "outer", etc., 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 application 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 application.

[0021] like Figure 1-4 As shown, this utility model provides a telescopic umbrella handle, including an umbrella handle body 1, a sleeve 2, and a handle base 3; The umbrella handle body 1 is used to fix it to the end of the umbrella pole 4. The end of the umbrella handle body 1 has a mounting hole 12 for mounting and fixing the end of the umbrella pole 4. The umbrella handle body 1 and the umbrella pole 4 can be fixedly connected or detachably installed, without specific restrictions. Sleeve 2 is fitted over the umbrella handle body 1. Sleeve 2 has a cylindrical structure and its inner wall is annular. The handle 3 is rotatably connected to the end of the sleeve 2 away from the umbrella rod 4. The handle 3 rotates circumferentially relative to the sleeve 2 around the axis of the sleeve 2. The sleeve 2 and the handle 3 are axially engaged, so that the sleeve 2 and the handle 3 can only rotate relative to each other in the circumferential direction. The axial engagement between the sleeve 2 and the handle 3 can be achieved by forming a slot on the top surface of the handle 3, with the side wall of the slot protruding radially inward to form a protrusion. The outer contour of the protrusion is arc-shaped. An annular groove that mates with the protrusion is formed on the side wall of the sleeve 2. After the bottom end of the sleeve 2 is inserted into the slot, the protrusion slides into the annular groove to form an axial engagement. Of course, in other embodiments, other engagement methods can also be used, without specific limitations.

[0022] One of the sleeve 2 and the handle seat 3 is spirally connected to the umbrella handle body 1, so that the umbrella handle body 1 can extend or retract from the sleeve 2 towards the umbrella shaft 4 by rotating relative to the umbrella handle body 1. The other of the sleeve 2 and the handle seat 3 is slidably connected to the umbrella handle body 1 along the direction of the umbrella handle body 1 extending from the sleeve 2 and retracting, and is circumferentially engaged with the umbrella handle body 1 to drive the umbrella handle body 1 to rotate, or to restrict the rotation of the umbrella handle body 1. The axis of the sleeve 2 is parallel to the direction of the umbrella handle body 1 extending from the sleeve 2 and retracting. In use, the handle seat 3 is driven to rotate circumferentially relative to the sleeve 2, so that the umbrella handle body 1 can extend from the sleeve 2 to lengthen the umbrella handle 5 for hand grip, or to retract the umbrella handle body 1 back into the sleeve 2 to shorten the umbrella handle 5 for easy storage.

[0023] The handle base 3 is shaped like a ping-pong ball, and its outer edge extends toward the sleeve 2 to form an irregular wave-like undulating annular baffle 34. The annular baffle 34 surrounds the outer perimeter of the sleeve 2, making the umbrella handle 5 aesthetically pleasing and easily recognizable.

[0024] Example 1 Key points combined Figure 3-4 As shown, the sleeve 2 is spirally connected to the umbrella handle body 1, and the handle seat 3 is axially slidably connected to the umbrella handle body 1 and circumferentially engaged, so that after the handle seat 3 rotates relative to the sleeve 2, it can drive the umbrella handle body 1 to rotate circumferentially. Specifically, the handle seat 3 extends towards the umbrella handle body 1 to form a guide member 31, and a groove 32 is formed on the guide member 31. The groove 32 extends axially, and a pin 11 protrudes from the outer side wall of the umbrella handle body 1. The pin 11 is inserted into and slidably engaged in the groove 32, so that the umbrella handle body 1 is slidably set on the handle seat 3 and circumferentially engaged with the handle seat 3. Of course, in other embodiments, the sliding engagement between the umbrella handle body 1 and the handle seat 3 is... The structure can also be such that the handle base 3 extends toward the umbrella handle body 1 to form a snap-fit ​​component, and a sliding groove for inserting the snap-fit ​​component is formed on the umbrella handle body 1. The snap-fit ​​component can slide axially in the sliding groove. The groove can be cross-shaped, triangular, etc., without specific limitations. Those skilled in the art can design and select according to specific circumstances. Preferably, the sliding groove 32 radially passes through the guide component 31, and the inner sidewall of the sleeve 2 has a spiral groove 21 extending circumferentially. The pin 11 passes through the sliding groove 32, and the end of the pin 11 is inserted into the spiral groove 21, so that the umbrella handle body 1 and the sleeve 2 are spirally connected.

[0025] In this specific embodiment, the guide member 31 is a ring-shaped structure that surrounds the outer periphery of the umbrella handle body 1. There are two sliding grooves 32, which are respectively arranged on opposite sides of the guide member 31. There are two pins 11, with one pin 11 slidingly engaged in one sliding groove 32, making the axial sliding between the umbrella handle body 1 and the handle seat 3 more stable. In use, the sleeve 2 is held and fixed, and then the handle seat 3 is rotated relative to the sleeve 2, which can drive the umbrella handle body 1 to rotate circumferentially, so that the pin 11 spirals up or spirals down along the extension direction of the spiral groove 21, thereby driving the umbrella handle body 1 to move axially to extend or retract from the sleeve 2.

[0026] Preferably, the pin 11 is detachably mounted on the umbrella handle body 1, the umbrella handle body 1 has a threaded hole, one end of the pin 11 has an external thread, and the pin 11 is screwed and fixed on the threaded hole, which facilitates disassembly to replace the pin 11. In other embodiments, the pin 11 can also be fixed by snap-fit, without specific limitations. Those skilled in the art can design according to specific circumstances.

[0027] Key points combined Figure 3 As shown, the two ends of the slide groove 32 extend circumferentially to form limiting grooves 33. The two limiting grooves 33 extend in opposite directions so that when the umbrella handle body 1 is extended to its longest or retracted to its smallest, the pin 11 slides into the limiting groove 33. The limiting groove 33 is used to restrict the axial movement of the pin 11.

[0028] Example 2 The difference between this specific embodiment and Embodiment 1 is that the sleeve 2 is axially slidably connected to the umbrella handle body 1, and the handle seat 3 is helically connected to the umbrella handle body 1. Specifically, the inner sidewall of the sleeve 2 extends axially to form a sliding groove, and there are multiple sliding grooves distributed in a circumferential ring array. The outer sidewall of the umbrella handle body 1 bulges radially outward to form a protrusion, which slides and engages with the sliding groove circumferentially. The handle seat 3 is helically connected to the umbrella handle body 1, and the handle seat 3 extends axially toward the umbrella handle body 1 to form a screw. The extension direction of the screw is parallel to the sliding groove. The extension direction is consistent. A threaded hole is formed on the umbrella handle body 1 to cooperate with the screw. The threaded hole extends axially and the length of the threaded hole matches the length of the screw. The specific length can be designed according to the extension length of the umbrella handle body 1 so that after the handle seat 3 rotates relative to the umbrella handle body 1, it can drive the umbrella handle body 1 to extend or retract from the sleeve 2 in the direction of the umbrella shaft 4. When in use, hold the sleeve 2 with your hand and rotate the handle seat 3 so that the handle seat 3 rotates circumferentially relative to the sleeve 2. Since the sleeve 2 and the umbrella handle body 1 are circumferentially engaged and limited, the umbrella handle body 1 can only move along the extension direction of the sliding groove.

[0029] The above description is only a preferred embodiment of this utility model and is not intended to limit the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
