Abstract
Description
Technical Field
[0001] This utility model relates to the field of automatic umbrella switch technology, and in particular to an automatic umbrella push-type umbrella opening device. Background Technology
[0002] Existing automatic umbrellas typically open and close by pressing a button. These umbrellas typically include a central stem, an upper recess, a mounting base, and a lower recess. The upper and lower recesses are mounted on the upper and lower ends of the central stem, respectively. The mounting base is fitted over the lower end of the lower recess. A notch is located on the outer wall of the central stem. The mounting base contains a hook and a control switch that moves the hook towards the notch. The control switch has a U-shaped piece, a pressure plate, and a return spring. An opening extending vertically is located on the outer wall of the mounting base. The U-shaped piece lies horizontally with its open end facing the opening. A hook protrudes from the inner wall of the U-shaped piece at the U-bend, allowing it to extend into the notch. A return spring is mounted on the outer wall of the U-shaped piece at the U-bend, lying horizontally with one end fixed to the U-shaped piece and the other end inserted into and fixed within the mounting base. The pressure plate is located at the opening and is mounted on the mounting base in a manner that allows the U-shaped piece to move horizontally along the inward and outward directions of the mounting base, causing the hook to enter or disengage from the notch. When using it, press the tab to disengage the hook from the notch and open the umbrella.
[0003] However, the button on this type of push-button umbrella poses a certain danger, as it is easily triggered and can be accidentally opened during transportation. Furthermore, accidental activation of the opening switch or dropping the umbrella can easily cause it to open, posing a safety hazard to the user. Therefore, an automatic push-type umbrella opening device is developed to prevent accidental activation of the umbrella switch. For example, the automatic push-type umbrella opening device with application number 2024213078624 includes an outer shell, an inner shell, and a switch. The outer shell is fitted over the inner shell. The switch has an inner sliding sleeve and an outer push block. The inner sliding sleeve is fitted into the inner shell in a manner that allows it to slide laterally along the inner shell. The inner shell has a limiting structure that restricts the vertical movement of the inner sliding sleeve. An exposure hole is provided on the outer wall of the inner shell facing away from the tensioning element to expose the inner sliding sleeve. A tensioning element is provided between the outer wall of the inner sliding sleeve and the inner wall of the inner shell. The side wall is provided with a limiting mechanism that can extend into the recessed opening under the umbrella. The outer push block is installed outside the inner shell in a way that can be pushed up and down. The outer shell has an operating hole for the outer push block to be partially exposed and can be pushed up and down on the outer shell. The tensioning member is arranged laterally opposite to the outer push block. The bottom surface of the inner translation sleeve has a guide block within the exposed hole range. The side of the guide block facing the outer push block is a guide inclined surface that slopes downward from top to bottom. The side of the outer push block facing the exposed hole is provided with a push block located below the guide block. The push block is provided with a pulley structure that slides into the guide inclined surface and slides along the guide inclined surface as the outer push block moves upward. In application, the outward push block moves axially upwards. The up-and-down movement of the outward push block causes the pulley to push the inner translation sleeve backwards, causing the inner translation sleeve to move backwards. This compresses the tensioning element, separating the limiting mechanism from the umbrella notch, thus opening the umbrella. After opening, the inner translation sleeve returns to its forward position due to the return force of the tensioning element, while the outward push block returns to its downward position due to its own weight and the return force of the inner translation sleeve. However, the pushing force of the inner translation sleeve is a back-and-forth motion, while the downward push of the outward push block is a vertical motion. This lack of downward force prevents the outward push block from fully returning to its original position.
[0004] In view of this, the inventors of this case conducted in-depth research on the problem, which led to the creation of this case. Utility Model Content
[0005] The purpose of this invention is to provide an automatic umbrella push-type umbrella opening device to solve the problem that the push block of the existing umbrella opening device cannot fully return.
[0006] To achieve its purpose, this utility model adopts the following technical solution:
[0007] An automatic umbrella-pushing type opening device includes an outer shell, an inner shell, and a switching component. The outer shell is fitted over the inner shell. The switching component has an inner translation sleeve and an outer push block. The inner translation sleeve is embedded in the inner shell in a manner that allows it to translate laterally along the inner shell. The outer push block is confined within the outer shell in a manner that allows it to be pushed up and down along the outer wall of the inner shell and pushes the inner translation sleeve to translate laterally. The outer shell has an operating hole for partially exposing the outer push block and allowing it to be pushed up and down on the outer shell. The device is characterized in that: an elastic restoring element capable of generating elastic restoring force is provided above and / or below the inner translation sleeve within the outer shell; the outer push block has a cooperating structure that, with the up and down pushing action of the outer push block, acts on the elastic restoring element to generate a pre-restoring force; and the outer push block and the inner translation sleeve have a pushing structure that, with the up and down pushing action of the outer push block, allows the inner translation sleeve to translate laterally.
[0008] With the position of the push block as the front, the elastic return member is vertically arranged above and / or below the inner translation sleeve, with one end of the elastic return member in contact with the inner shell and the other end in contact with the mating structure, which is located between the elastic return member and the inner translation sleeve.
[0009] An exposed hole is provided on the front outer side wall of the inner housing to expose the front side of the inner translation sleeve. The exposed hole is within the operating hole range, and the inner bottom surface and / or the inner top surface of the exposed hole are recessed to provide a receiving groove that leads to the front side of the inner housing. The elastic recovery member is erected in the receiving groove, and the rear side of the push block is provided with an upper pressing block on the bottom surface of the upper elastic recovery member at the position corresponding to the upper receiving groove, and / or the rear side of the push block is provided with a lower pressing block on the top surface of the lower elastic recovery member at the position corresponding to the lower receiving groove. The upper pressing block and / or the lower pressing block constitute the above-mentioned mating structure.
[0010] The front side of the inner translation sleeve is provided with an inclined surface, and the rear side of the outer push block is provided with a push block that is opposite to the inner translation sleeve and slides into the inclined surface as the outer push block is pushed up and down and slides along the inclined surface to move the inner translation sleeve backward. The inclined surface and the push block constitute the above-mentioned push structure.
[0011] The lower end of the front side of the inner translation sleeve is provided with a first inclined surface that slopes downward from top to bottom. The first inclined surface is the aforementioned inclined surface, and the pushing block is located below the first inclined surface.
[0012] The upper end of the front side of the inner translation sleeve is provided with a second inclined surface that slopes upward from bottom to top. The second inclined surface is the aforementioned inclined surface, and the pushing block is located above the second inclined surface.
[0013] The front side of the inner translation sleeve is provided with an upper inclined surface that slopes upward from bottom to top and a lower inclined surface that slopes downward from top to bottom. The upper and lower inclined surfaces are spaced apart and form a horn space that gradually narrows from front to back. The pushing block falls into the horn space. The upper and lower inclined surfaces constitute the aforementioned inclined surfaces.
[0014] The front side of the inner translation sleeve is recessed between the upper and lower inclined surfaces, and has an accommodating opening that leads to the hollow cavity of the inner translation sleeve. The rear part of the pushing block is within the accommodating opening.
[0015] The pushing block is a convex arc block that bulges backward.
[0016] The push block is a strip-shaped sheet extending in the vertical direction, and the push block is a strip-shaped arc-shaped block extending in the width direction of the push block and protruding backward. A circular slider is rotatably mounted on the strip-shaped arc-shaped block, the outer wall of which extends in the same arc direction as the outer wall of the strip-shaped arc-shaped block.
[0017] This novel automatic umbrella-opening device, when applied, involves pushing the outer push block upwards or downwards. Through the interaction between the outer push block and the pushing structure on the inner sliding sleeve, the inner sliding sleeve moves horizontally along its sides, causing the limiting mechanism of the inner sliding sleeve to disengage from the umbrella notch, thus opening the umbrella. After opening, releasing the thrust on the outer push block causes the outer push block and its pushing structure to reset under the action of the elastic return member. When the outer push block is pushed upwards to activate the opening device, the outer push block and its pushing structure reset downwards; when the outer push block is pushed downwards to activate the opening device, the outer push block and its pushing structure reset upwards. Compared to existing technologies, the elastic return member generates a pre-restoring force on the bottom and / or top surface of the inner sliding sleeve, ensuring the outer push block fully returns to its original position.

[0030] To further explain the technical solution of this utility model, a detailed description is provided below in conjunction with the accompanying drawings.
[0031] The automatic umbrella-pushing type umbrella opening device of this utility model, in embodiment one, is as follows: Figures 1-5As shown, the device includes an outer shell 1, an inner shell 2, and a switch. The outer shell 1 is fitted over the inner shell 2. The switch has an inner translation sleeve 3 and an outer push block 4. The inner translation sleeve 3 is fitted inside the inner shell 2 so as to be able to translate laterally along the inner shell 2. The outer push block 4 is positioned inside the outer shell 1 so as to be able to push up and down along the outer wall of the inner shell 2 and push the inner translation sleeve 3 to translate laterally. The outer shell 1 has an operating hole 100 for partially exposing the outer push block 4 and for pushing it up and down on the outer shell 1. Specifically, the inner translation sleeve 3 has an arc-shaped block 31 and two horizontal blocks 32. There are two horizontal blocks 32 and two arc-shaped blocks 31. The two horizontal blocks 32 are arranged at intervals relative to each other. The horizontal block 32 extends along the front-to-back direction, and the two arc-shaped blocks 31 are respectively located on the front and rear sides of the horizontal block 32. The two arc-shaped blocks 31 are positioned between the two horizontal blocks 32 and are arranged opposite each other, with their convex arc surfaces facing away from each other. Among the two arc-shaped blocks 31, the arc-shaped block 31 on the front side is the front arc-shaped block 311, and the arc-shaped block 31 on the rear side is the rear arc-shaped block 312. That is, the front arc-shaped block 311 protrudes forward, and the rear arc-shaped block 312 protrudes backward. Both the outer shell 1 and the inner shell 2 are hollow structures that extend vertically. The upper inner wall of the inner shell 2 has a limiting groove that extends along the inner wall of the inner shell and allows the inner translation sleeve 3 to be fitted inside. A tension spring extending in the front-rear direction and connected to the rear inner wall of the limiting groove is provided on the rear side of block 312. A limiting block 3121 that can extend into the umbrella notch is protruding from the front inner wall of the rear arc-shaped block 312. An exposure hole is provided on the front outer wall of the inner shell 2 to expose the front side of the front arc-shaped block 311. The exposure hole is within the range of the operating hole 100. A translation groove is recessed in the front side wall of the inner shell 2. The translation groove is a strip-shaped groove extending in the vertical direction. The exposure hole is within the range of the translation groove. The push block 4 is within the range of the translation groove, and the vertical dimension of the translation groove is greater than the vertical dimension of the push block 4, i.e., the push block 4 is larger than the vertical dimension of the push block 4. Block 4 has an arc-shaped plate 41 and a pushing protrusion 42. The arc-shaped plate 41 is a strip-shaped convex arc structure that extends in the vertical direction and protrudes forward. The pushing protrusion 42 extends in the vertical direction and is located on the front side of the arc-shaped plate and falls into the range of the operating hole 100. The arc-shaped plate 41 is able to be pushed up and down in the translation groove and is limited to the translation groove range by the outer shell 1 sleeved outside the inner shell 2. The installation method of the outer shell 1 and the inner shell 2, the installation method of the inner translation sleeve 3 laterally translating in the inner shell, and the method of the outer push block 4 being pushed up and down along the outer side wall of the inner shell 2 and limited to the outer shell 1 are all known technologies and will not be described in detail here.
[0032] The outer shell 1 is provided with an elastic restoring element (not shown in the figure) above and / or below the inner translation sleeve 3, which can generate an elastic restoring force. The outer push block 4 is provided with a matching structure that, with the up and down pushing action of the outer push block 4, causes the elastic restoring element to generate a pre-restoring force. Specifically, the elastic restoring element is a vertically arranged compression spring. There are two elastic restoring elements, which are respectively vertically arranged above and below the inner translation sleeve 3. The opposite ends of the two elastic restoring elements are in contact with the inner shell 2, and the opposite ends of the two elastic restoring elements are in contact with the matching structure. The components are in contact, and the mating structure is located between the elastic return member and the inner translation sleeve. That is, both the inner bottom surface and the inner top surface of the exposed hole are recessed with receiving grooves 200 that extend to the front side of the inner housing 2. The elastic return member is vertically positioned within the receiving groove 200. Of the two elastic return members, the elastic return member above the inner translation sleeve 3 is the upper elastic return member, and the elastic return member below the inner translation sleeve 3 is the lower elastic return member. The receiving groove has a first groove 201 and a second groove 202, both of which are strip-shaped structures extending in the vertical direction. The inner diameter of the first groove 201 is larger than the inner diameter of the second groove 202. The two second grooves 202 are located between the two first grooves 201. The elastic recovery member stands upright in the first groove 201. The mating structure allows it to be pushed up and down along the second groove in the second groove 202. The upper receiving groove is the upper receiving groove, and the upper elastic recovery member stands upright in the first groove of the upper receiving groove. The lower receiving groove is the lower receiving groove, and the lower elastic recovery member stands upright in the first groove of the lower receiving groove. The rear side of the arc-shaped plate 41 corresponds to... An upper pressing block 51 protrudes from the second groove 202 of the upper receiving groove, positioned on the bottom surface of the upper elastic return member. A lower pressing block 52 protrudes from the rear side of the arc-shaped sheet 41, corresponding to the position of the second groove 202 of the lower receiving groove, positioned on the top surface of the lower elastic return member. The upper pressing block 51 and the lower pressing block 52 constitute the aforementioned mating structure. The lower end of the upper elastic return member is connected to the upper pressing block 51, and the upper end of the upper elastic return member is connected to the bottom of the upper receiving groove. The upper end of the lower elastic return member is connected to the lower pressing block 52, and the lower end of the lower elastic return member is connected to the bottom of the lower receiving groove. In application, if pushing the outer push block upwards can activate the entire umbrella opening device, a finger applies an upward pushing force to the outer push block 4. When the outer push block 4 is pushed upwards, the upper elastic return member is compressed, and then the force applied to the outer push block is released, causing the upper elastic return member to reset. The upper elastic return member applies a downward force to the upper pressing block 51, pushing the upper pressing block 51 downwards, and the outer push block 4 resets downwards. Conversely, if the outer push block can activate the entire umbrella opening device when pushed down, the finger applies a downward force to the outer push block. When the outer push block 4 is pushed down, the lower elastic return member is compressed, releasing the force applied to the outer push block. The lower elastic return member resets, and the lower elastic return member applies an upward force to the lower pressure block 52, pushing the lower pressure block 52 upward. The outer push block 4 resets upward.
[0033] The outer push block 4 and the inner translation sleeve 3 are provided with a pushing structure that allows the inner translation sleeve 3 to move laterally as the outer push block 4 is pushed up and down. Specifically, the front side of the inner translation sleeve 3 is provided with an inclined surface 6, and the rear side of the arc-shaped plate 41 is provided with a pushing block that is opposite to the inner translation sleeve 3 and slides into the inclined surface 6 as the pushing protrusion 42 is pushed up and down, and slides along the inclined surface 6 to move the inner translation sleeve 3 backward. The inclined surface 6 and the pushing block constitute the above-mentioned pushing structure, that is, the front side of the front arc-shaped block 311 is provided with an upwardly inclined surface 61 that slopes from bottom to top and a pushing block that slopes from bottom to top. The upper inclined surface 61 and the lower inclined surface 62 are arranged at intervals from top to bottom, and the upper inclined surface 61 and the lower inclined surface 62 form a horn space that gradually narrows from front to back. The pushing block falls into the range of the horn space. The upper inclined surface 61 and the lower inclined surface 62 constitute the aforementioned inclined surface 6. The front side of the inner translation sleeve 3 is recessed between the upper inclined surface 61 and the lower inclined surface 62 and has a receiving opening 300 that leads to the hollow cavity of the inner translation sleeve 3. The rear part of the pushing block is within the range of the receiving opening 300. The pushing block is a rearward convex arc block 71. In application, the upward push of the protrusion 42 causes the arc-shaped plate 41 to move upward along the translation groove, and the convex arc block 71 moves upward along the upper inclined surface 61. The convex arc surface of the convex arc block 71 contacts the upper inclined surface 61. As the convex arc block 71 moves upward, the upper inclined surface 61 is squeezed backward, causing the inner translation sleeve 3 to move backward. Since the distance between the upper inclined surface 61 and the rear side wall of the arc-shaped plate 41 gradually decreases from bottom to top, while the front-back dimension of the convex arc block 71 is fixed, the convex arc block 71 squeezes the upper inclined surface 61 upward when it moves upward. At the same time, the inner translation sleeve 3 is limited to horizontal movement by the vertical restriction groove. Therefore, when the convex arc block 71 enters the distance between the upper inclined surface 61 and the rear side wall of the arc-shaped plate 41, the convex arc block 71 generates a backward force on the upper inclined surface 61 when it moves from bottom to top, causing the inner translation sleeve 3 to move backward. Similarly, when the convex block 42 is pushed down, the arc-shaped plate 41 moves down along the translation groove, and the convex arc block 71 moves down along the lower inclined surface 62. The convex arc surface of the convex arc block 71 contacts the lower inclined surface 62. As the convex arc block 71 moves down, the lower inclined surface 62 is squeezed backward, causing the inner translation sleeve 3 to move backward. Since the distance between the lower inclined surface 62 and the rear side wall of the arc-shaped plate 41 gradually decreases from top to bottom, while the front-back dimension of the convex arc block 71 is fixed, the convex arc block 71 squeezes the lower inclined surface 62 downward when it moves down. At the same time, the inner translation sleeve 3 can only move horizontally due to the limitation of the groove in the vertical direction. Therefore, when the convex arc block 71 enters the distance between the lower inclined surface 62 and the rear side wall of the arc-shaped plate 41, the convex arc block 71 generates a backward force on the lower inclined surface 62 when it moves from top to bottom, causing the inner translation sleeve 3 to move backward. In this way, the inner translation sleeve 3 can be used to activate the entire parachute opening device by pushing the outer push block 4 upwards and by pushing the outer push block 4 downwards.
[0034] In this novel automatic umbrella-pushing type opening device, when the outer push block 4 is pushed upward, the convex arc block 71 moves upward from the accommodating opening 300 along the upper inclined surface 61. During the continuous upward movement of the convex arc block 71, it presses backward against the upper inclined surface 61, causing the inner translation sleeve 3 to move backward. This causes the limiting block 3121 of the inner translation sleeve 3 to disengage from the umbrella notch, thus opening the umbrella. Simultaneously, the upper pressure block 51 moves upward along the second groove of the upper accommodating groove, following the outer push block 4. The upper pressure block 51 applies an upward force to the upper elastic return member, compressing it upward. The lower pressure block 52 moves upward along... The second groove of the lower receiving slot moves upward with the push block 4, and the lower pressing block 52 applies an upward force to the lower elastic return member, which is stretched upward. After the umbrella opens, the force on the push block 4 is released, the upper elastic return member is released, and the reaction force of the upper elastic return member on the upper pressing block 51 generates a downward pushing force on the upper pressing block 51. The upper pressing block 51 moves downward along the second groove of the upper receiving slot, and the convex arc block 71 slides downward along the upper inclined surface 61 into the receiving opening 300. The push block 4 then resets downward, and both the upper and lower elastic return members are reset to an uncompressed state. Similarly, when the outer push block 4 is pushed down, the convex arc block 71 moves downward from the receiving opening 300 along the lower inclined surface 62. As the convex arc block 71 moves downward continuously, it presses backward against the lower inclined surface 62, causing the inner translation sleeve 3 to move backward. This causes the limiting block 3121 of the inner translation sleeve 3 to disengage from the umbrella notch, thus opening the umbrella. At the same time, the lower pressing block 52 moves downward along the second groove of the lower receiving groove, following the outer push block 4. The lower pressing block 52 applies a downward force to the lower elastic recovery member, compressing it downward. The upper pressing block 51 moves downward along the second groove of the upper receiving groove. The groove moves downward with the push block 4, and the upper pressure block 51 applies a downward force to the upper elastic return member, causing the upper elastic return member to stretch downward. After the umbrella opens, the force on the push block 4 is released, the lower elastic return member is released, and the reaction force of the lower elastic return member on the lower pressure block 52 generates an upward pushing force on the lower pressure block 52, causing the lower pressure block 52 to move upward along the second groove of the lower receiving groove. The convex arc block 71 slides upward along the lower inclined surface 62 into the receiving opening 300, and the push block 4 then resets upward. Both the upper and lower elastic return members are reset to an uncompressed state. Compared with the prior art, through the guiding cooperation of the inclined surface and the convex arc block, pushing the push block 4 upward or downward can cause the limiting block 3121 to disengage from the umbrella notch, thus realizing the opening of the umbrella. When the outer push block 4 is pushed upward, it can automatically reset downward due to the action of the upper elastic return member, and can reset more quickly under the stretching of the lower elastic return member; when the outer push block 4 is pushed downward, it can automatically reset upward due to the action of the lower elastic return member, and can reset more quickly under the stretching of the upper elastic return member.
[0035] The automatic umbrella-pushing type umbrella opening device of this utility model, in embodiment two, is as follows: Figure 6As shown, the difference between this and Embodiment 1 is that the inclined surface of the inner translation sleeve 3 is only a single inclined surface that slopes downwards from top to bottom. Specifically, the bottom front surface of the inner translation sleeve 3 has a first protrusion 33, the pressing block is located below the first protrusion 33, the inclined surface 6 has a first inclined surface 331 located on the front side of the first protrusion 33 and sloping downwards from top to bottom, and the lower elastic recovery member is located below the first protrusion 33; or the first inclined surface 331 is directly provided on the lower end of the front side of the inner translation sleeve 3, or the aforementioned first inclined surface sloping downwards from top to bottom is directly provided on the lower end of the front side of the inner translation sleeve 3. In application, the outer push block 4 is pushed up, and the convex arc block 71 moves upwards along the first inclined surface 331. During the continuous upward movement of the convex arc block 71, the convex arc block 71 presses the first inclined surface 331 backwards, causing the inner translation sleeve 3 to move backwards, causing the limiting block 3121 of the inner translation sleeve 3 to disengage from the umbrella notch, thus opening the umbrella.
[0036] The automatic umbrella-pushing type umbrella opening device of this utility model, in embodiment three, is as follows: Figure 7 As shown, the difference between this embodiment and Embodiment 1 is that the inclined surface of the inner translation sleeve 3 is only one inclined surface that slopes upward from bottom to top. Specifically, the top front surface of the inner translation sleeve 3 has a second protrusion 34, the upper pressing block is above the second protrusion 3, the inclined surface 6 has a second inclined surface 341 that is located on the front side of the second protrusion 34 and slopes upward from bottom to top, and the pushing block is above the second inclined surface 6; or the aforementioned second inclined surface 341 that slopes upward from bottom to top is directly provided on the upper end of the front side of the inner translation sleeve 3. In application, the outer pushing block 4 is pushed down, and the convex arc block 71 moves downward along the second inclined surface 341. During the continuous downward movement of the convex arc block 71, the convex arc block 71 presses the second inclined surface 341 backward, causing the inner translation sleeve 3 to move backward, so that the limiting block 3121 of the inner translation sleeve 3 disengages from the umbrella notch, thus opening the umbrella.
[0037] The automatic umbrella-pushing type umbrella opening device of this utility model, in embodiment four, is as follows: Figures 8-9As shown, the difference between this embodiment and Embodiment 1 lies in the specific structure of the pushing block; specifically, the pushing protrusion 42 is a rectangular structure extending in the vertical direction, and the pushing block is a strip-shaped arc-shaped block 72 extending along the width direction of the pushing protrusion 42 and protruding backward. A circular slider 721 is rotatably mounted on the strip-shaped arc-shaped block 72, the outer wall of which extends in the same arc direction as the outer wall of the strip-shaped arc-shaped block 72. That is, the circular slider 721 has a sliding wheel and a sliding shaft. The sliding wheel is rotatably sleeved on the sliding shaft, and the two ends of the sliding shaft are... The strip-shaped arc block 72 has a strip-shaped connecting groove and a limiting groove recessed on its rear outer side wall, extending beyond both ends of the sliding wheel. The strip-shaped connecting groove extends along the width direction of the arc-shaped plate 41, and its extension direction is perpendicular to the axis of the inner translation sleeve 3. The limiting groove is located in the middle of the strip-shaped connecting groove, and extends beyond both ends of the limiting groove. The sliding shaft is embedded in the strip-shaped connecting groove, and the sliding wheel is located in the limiting groove. The surface of the sliding wheel is similar to the curvature of the convex arc surface of the strip-shaped arc block. In application, when the outer push block 4 is pushed up or down, the strip-shaped arc block 72, in conjunction with the sliding wheel, makes the upward or downward push of the outer push block 4 smoother.
[0038] The automatic umbrella-pushing type umbrella opening device of this utility model, in embodiment five, is as follows: Figures 10-12 As shown, the difference between this embodiment and Embodiment 2 is that the mating structure only includes the aforementioned upper pressure block 51, without the lower pressure block 52, and only the aforementioned upper elastic recovery member is provided, without the lower elastic recovery member; specifically, the inner top surface of the exposed hole of the inner shell 2 is recessed with the aforementioned upper receiving groove that extends to the front side of the inner shell 2, and the mating structure includes an upper pressure block 51 located on the upper rear side of the arc-shaped sheet 41, the upper pressure block 51 being located in the lower end of the upper receiving groove, the upper elastic recovery member being located in the upper end of the upper receiving groove, the lower end of the upper elastic recovery member being connected to the upper pressure block 51, and the upper end of the upper elastic recovery member being connected to the bottom of the upper receiving groove. In application, this structure is suitable for the external push block 4 to push up and start the umbrella opening device. When the external push block 4 is pushed up, the convex arc block 71 presses the first inclined surface 331 backward, so that the inner translation sleeve 3 moves backward and realizes the opening of the umbrella. After the umbrella is opened, the upper elastic return member can push the upper pressure block 51 downward, so that the external push block 4 moves downward and resets.
[0039] The automatic umbrella-pushing type opening device of this utility model, in embodiment six, differs from embodiment three in that: the mating structure only includes the aforementioned lower pressing block 52, without the upper pressing block 51, and only the aforementioned lower elastic recovery member is provided, without the upper elastic recovery member; specifically, the inner bottom surface of the exposed hole of the inner shell 2 is recessed with the aforementioned lower receiving groove that leads to the front side of the inner shell 2, and the mating structure includes the lower pressing block 52 located on the lower rear end of the arc-shaped plate 41, the lower pressing block 52 being located in the upper end of the lower receiving groove, the lower elastic recovery member being located in the lower end of the lower receiving groove, the upper end of the lower elastic recovery member being connected to the lower pressing block 52, and the lower end of the lower elastic recovery member being connected to the bottom of the lower receiving groove. In application, this structure is suitable for use when the outer push block 4 is pushed down to activate the umbrella opening device. When the outer push block 4 is pushed down, the convex arc block 71 presses the second inclined surface 341 backward, causing the inner translation sleeve 3 to move backward and open the umbrella. After the umbrella opens, the lower elastic return member can push the lower pressure block 52 upward, causing the outer push block 4 to move upward and reset. In this new invention, the elastic return member is located above and / or below the inner translation sleeve, the corresponding matching structure is matched with the elastic return member, and the specific structure of the pushing structure is adapted according to actual needs and user habits. Only a few embodiments are listed here, and not all are listed.
[0040] The product form of this utility model is not limited to the illustrations and embodiments in this case. Any appropriate changes or modifications made to it based on similar ideas should be considered as not departing from the patent scope of this utility model.
