Technical Field
[0001] This utility model relates to the field of umbrella products technology, and in particular to an automatic umbrella mounting base. Background Technology
[0002] Existing automatic umbrella mounting bases, such as the one described in application number 2022226023067, include a base body and a pressure plate. The base body has a hollow structure with openings at both ends, and openings are formed on the side walls of the base body. The pressure plate is mounted on the base body in a manner that allows it to translate inwards and outwards and is positioned at the openings. The base body is equipped with a reset device for controlling the return of the umbrella's bullet-shaped tip, with the translational direction of the pressure plate defined as the front-back direction. The reset device includes an elastic element and a pressing block, the pressing block being a hollow block with open upper and lower ends. The aforementioned pressing block is movably placed in the seat body in a manner that allows it to move up and down. The aforementioned elastic element is placed vertically in the seat body and below the pressing block, with the pressing block stacked on the aforementioned elastic element. The aforementioned opening is located on the front side wall of the seat body. The inner side wall of the pressing block is provided with a push block that can extend into the pressing hole of the central rod and support the outer umbrella rod. The outer side wall of the pressing block is provided with a guide block that protrudes outward. The inner side wall of the seat body is provided with a sliding groove that allows the guide block to extend into it and slide along the front-back direction and the up-down direction of the seat body. In addition, this mounting base also includes a hook structure that hooks with the locking hole of the outer umbrella pole. This hook structure has a U-shaped piece and a spring. The U-shaped piece is horizontally arranged in the base body in a way that allows it to move back and forth. The spring is located behind the U-shaped piece. The opening of the U-shaped piece faces the opening of the base body, which is equivalent to being set forward. The rear side of the pressure plate contacts the front end of the U-shaped piece. The inner wall of the U-shaped piece at the U-shaped bend has protruding locking teeth. The outer wall of the outer umbrella pole has locking holes for the locking teeth to engage. In application, pressing the pressure plate for the first time causes the U-shaped piece above the pressure block to move outward under the compression of the tension spring. The locking teeth of the U-shaped piece disengage from the locking holes of the outer umbrella rod, and the outer umbrella rod moves upward to open the umbrella. At this time, the compressed elastic element returns to its original position, the pressure block moves upward, and the push block falls into the pressure hole of the central rod. Pressing the pressure plate again pushes the umbrella bullet head to close the umbrella and pushes the outer umbrella rod downward. The downward movement of the outer umbrella rod causes the pressure block to be impacted and move downward under the compression of the columnar spring. The lower end of the outer umbrella rod abuts against the top surface of the push block. At the same time, the downward movement of the outer umbrella rod pushes the U-shaped piece outward. When the locking hole of the outer umbrella rod moves down to the locking teeth, the U-shaped piece moves inward under the reset of the tension spring, causing the locking teeth to engage in the locking hole again, thus closing the umbrella.
[0003] However, in the above-mentioned automatic umbrella mounting base, when the umbrella is closed, the lower end of the outer umbrella rod presses against the top surface of the push block. The push block is a small block that extends into the recess of the central rod. The downward pressure of the outer umbrella rod is entirely applied to the push block, which can easily lead to damage to the push block.
[0004] Furthermore, when installing the hook rod structure, the spring and U-shaped plate need to be installed together first, and then the spring and U-shaped plate are installed together in the seat. However, the U-shaped plate is relatively thin, the contact area between the spring and the U-shaped plate is small, the spring is not easy to fix, and after the spring makes repeated elastic movements, the spring is easy to deviate from the U-shaped plate, resulting in the U-shaped plate not fully returning to its original position.
[0005] In view of this, the inventors of this case conducted in-depth research on the problem, which led to the creation of this case. Summary of the Invention
[0006] The purpose of this utility model is to provide an automatic umbrella mounting base to solve the problem that the push block of the existing automatic umbrella mounting base is easily damaged.
[0007] Another objective of this invention is to provide an automatic umbrella mounting base to solve the problem of incomplete U-shaped plate repositioning in existing automatic umbrella mounting bases. To achieve its purpose, this utility model adopts the following technical solution: An automatic umbrella mounting base includes a base body, a pressure plate, a hook structure, and a reset device. The base body has a hollow structure with an opening on its side wall. The pressure plate is mounted on the base body and positioned at the opening, allowing it to translate along the inner and outer directions of the base body. The hook structure and reset device are mounted inside the base body, with the translational direction of the pressure plate as the front-back direction. The reset device includes a hook block and a lifting block. The lifting block is mounted on the pressure plate and exposed outside the pressure plate, allowing it to move up and down. Both the pressure plate and the lifting block are provided with an upward restoring force that occurs as the lifting block moves downward. The lifting and restoring force generating mechanism includes a lifting block with a support device inside the seat for pressing the outer umbrella rod onto it. The hook rod structure is located above the support device. The hook block is installed on the seat in a way that allows it to move back and forth and is located behind the pressure plate. The support device is located above the hook block. A translational restoring force generating mechanism is installed inside the seat to generate a forward restoring force as the hook block moves backward. The side of the hook block facing the opening has a limiting block that can extend into the pressing hole of the central rod. The lifting block is provided with a pushing structure that can push the hook block backward as the pressure plate moves backward.
[0008] The pressing plate is a strip-shaped arc plate extending in the vertical direction. The rear side of the pressing plate is recessed with a vertically penetrating rear lifting groove. The upper bottom of the rear lifting groove is recessed forward with a strip-shaped front lifting groove that extends to the outside of the top surface of the pressing plate. The front lifting groove extends in the vertical direction and penetrates in the front and back. The front part of the lifting block is slidably installed in the upper end of the front lifting groove. The lifting and restoring force generating mechanism is vertically limited between the lower groove wall of the front lifting groove and the front end of the lifting block. The rear part of the lifting block is vertically installed in the rear lifting groove. The pushing structure is located on the lower rear side of the lifting block and is arranged opposite to the hook block. The supporting device is located on the upper rear side of the lifting block and is suspended above the hook block.
[0009] The lifting block has a front lifting part and a rear lifting part, both of which are strip-shaped blocks extending in the vertical direction. The front lifting part is upright in the upper end of the front lifting groove. The left and right inner walls of the front lifting groove are both provided with guide strips extending in the vertical direction. The left and right sides of the front lifting part are recessed with guide grooves for the guide strips to extend into. The upper ends of the two guide strips are provided with anti-detachment blocks to prevent the front lifting part from falling out of the front lifting groove. The bottom surface of the front lifting part is recessed with an embedding groove. The inner bottom surface of the front lifting groove is provided with an embedding block opposite to the embedding groove. The lifting return force generating mechanism is a lifting spring. The upper end of the lifting spring is embedded in the embedding groove, and the embedding block extends into the lower end of the lifting spring. The rear lifting part is upright in the rear lifting groove, and the top surface of the rear lifting part is flush with the top surface of the pressure plate. The bottom surface of the rear lifting part is flush with the bottom surface of the pressure plate. The pushing structure is located at the lower rear end of the rear lifting part.
[0010] The support device has two support bars, both of which extend in the front-to-back direction and are spaced apart in the left-to-right direction on the upper rear side of the rear lifting part. The two support bars are located below the hook structure and within the range of the hook structure. There is a movable gap between the bottom surface of the support bar and the top surface of the hook block.
[0011] The base has an upper base, a lower base, and a mounting body between the upper and lower bases. The mounting body is a hollow cylindrical structure that extends vertically. The upper and lower bases respectively seal the bottom and top surfaces of the mounting body. The upper base has an upper through hole that extends vertically and allows the middle rod and outer umbrella rod to extend into it. The lower base has a lower through hole that allows the middle rod to extend outward. The front side of the mounting body has a recessed opening that communicates with the hollow cavity of the mounting body and extends vertically. The rear side of the pressure plate is parallel to the front side of the mounting body. The hook rod structure and hook block are installed in the mounting body.
[0012] A partition plate is horizontally arranged at the lower end of the mounting body. The partition plate is suspended above the top surface of the lower base body. The top surface of the partition plate is recessed with an outlet for the middle rod to extend outward. The outlet extends vertically and reaches the front side of the partition plate. A translation groove is formed between the partition plate, the top surface of the lower base body, and the inner side of the mounting body, allowing the hook block to move back and forth. The translational restoring force generating mechanism extends in the front-back direction and is located between the rear inner wall of the translation groove and the rear side of the hook block. The maximum dimension of the hook block in the front-back direction is smaller than the maximum distance in the front-back direction of the translation groove.
[0013] The hook block has a rear hook section and a front pushing section. Both the rear hook section and the front pushing section are strip-shaped structures. The rear hook section extends in the left-right direction. There are two front pushing sections, which extend in the front-back direction and are located on the left and right ends of the front side of the rear hook section, respectively. The limiting block is located on the front side of the rear hook section. There is a translation gap between the rear side of the rear hook section and the rear inner wall of the translation groove. A translation spring extending in the front-back direction is provided within the translation gap. This translation spring is a translation restoring force generating mechanism. The pushing structure is arranged opposite to the two front pushing sections.
[0014] The lower rear end of the lifting block is provided with a protrusion at the position in front of the two front pushing sections. The protrusion fits against the front of the front pushing section, and the two protrusions constitute the above-mentioned pushing structure.
[0015] The hook structure has a mounting block, a U-shaped piece, and an elastic element. The mounting block has a U-shaped structure with the front side open, and the front side of the mounting block is integrally formed with the upper rear side of the pressure plate. The inner wall of the seat body is recessed with a movable groove that communicates with the hollow cavity of the seat body and extends to the front side of the seat body. The mounting block is embedded in the movable groove in a way that allows it to move back and forth through the elastic element. The mounting block and the seat body are provided with a limiting structure to prevent the mounting block from completely moving out of the movable groove. The elastic element extends in the front-back direction and is disposed between the rear side of the mounting block and the rear inner side wall of the movable groove. The front end and rear end of the elastic element are respectively limited and connected to the rear side of the mounting block and the rear inner side wall of the movable groove through the mounting structure. The top surface of the mounting block is recessed with a slot that communicates with the hollow cavity of the mounting block. The U-shaped piece is embedded and limited in the slot. The front inner side wall of the U-shaped piece is protruding forward with a locking block that can extend into the pressing hole of the central rod.
[0016] The mounting block has protruding limiting strips extending vertically on both its left and right sides. The rear side walls of the movable groove have recessed limiting grooves extending horizontally and reaching the rear side of the seat. A partition block is formed between the two limiting grooves. The rear end of the elastic element is connected to the partition block for limiting. A limiting step surface is formed between the bottom of the two limiting grooves and the inner side wall of the movable groove. The limiting strip is located in the limiting groove, and the front side of the limiting strip is in contact with the limiting step surface. The limiting strip and the limiting groove constitute the above-mentioned limiting structure.
[0017] This novel automatic umbrella mounting base, in its application, when the umbrella is closed, causes the outer umbrella rod to move downwards, with its bottom pressing against the top surface of the support device. The lifting block moves downwards, and the lifting and restoring force generating mechanism generates an upward restoring force. This pushes the structure and the front side of the hook block, offset vertically to prevent accidental contact with the hook block. The first backward press of the pressure plate causes the hook structure to move backwards and disengage from the outer umbrella rod, allowing the outer umbrella rod to move upwards, thus opening the umbrella. At this time, the limiting block restricts the umbrella bullet head, the lifting block moves upwards, and the lifting and restoring force generating mechanism resets. The push structure and the hook block are then positioned opposite each other. The pressure plate is pressed backwards again, causing the push structure to press the hook block backwards. The hook block moves backwards, and the limiting block moves backwards and disengages from the pressing hole of the central rod, allowing the umbrella bullet head to reset, thus closing the umbrella. The outer umbrella rod is then pushed downwards, and the locking hole of the outer umbrella rod engages with the hook structure. The bottom surface of the outer umbrella rod presses against the top surface of the two support bars. The push structure and the front side of the hook block are offset vertically, thus closing the umbrella. Compared with existing technologies, when the outer umbrella rod and the hook rod structure are hooked together, the outer umbrella rod presses against the top surface of the support device. The downward pressure of the outer umbrella rod acts on the support device and not on the limiting block used to press the middle rod. This prevents the downward pressure of the outer umbrella rod from damaging the limiting block. Furthermore, the support device is mounted on the pressure plate. Even if damage occurs, only the lifting mechanism needs to be replaced, without disassembling and replacing the entire mounting base, resulting in lower maintenance costs. Attached Figure Description

[0025] To further explain the technical solution of this utility model, a detailed description is provided below in conjunction with the accompanying drawings.
[0026] An automatic umbrella mount, such asFigures 1-7 As shown, the device includes a base 1, a pressure plate 2, a hook rod structure 3, and a reset device. The base 1 has a hollow structure, and an opening 100 is provided on the side wall of the base 1. The pressure plate 2 is installed on the base in a manner that allows it to slide along the inside and outside of the base and is located at the opening 100. The hook rod structure 3 and the reset device are installed inside the base. Specifically, the base 1 has an upper base 11, a lower base 12, and a mounting body 13 located between the upper base 11 and the lower base 12. The mounting body 13 has a hollow cylindrical structure that extends vertically. The upper base 11 and the lower base 12 respectively seal the bottom and top surfaces of the mounting body 13. The upper base 11 has an upper through hole that extends vertically and allows the middle rod 111 and the outer umbrella rod 112 to extend into it. The lower base 12 has a lower through hole that allows the middle rod 111 to extend outward. The lower end of the middle rod 111 is connected to the lower base 11. The two components are connected together. The central rod 111 contains an umbrella bullet head 1111 for controlling the closing of the umbrella. The central rod 111 has a pressing hole corresponding to the lower end of the umbrella bullet head. The umbrella bullet head has a limiting groove, which forms a limiting step surface with the outer side of the umbrella bullet head. The front side of the mounting body 13 has an opening 100 that communicates with the hollow cavity of the mounting body 13 and extends in the vertical direction. The rear side of the pressure plate 2 is parallel to the front side of the mounting body 13. The hook rod structure 3 is installed in the mounting body 13. The specific installation structure of the umbrella bullet head 1111 and the method of closing the umbrella by pressing the umbrella bullet head 1111 are well known to those skilled in the art and will not be described in detail here. In application, the reset device activates the umbrella bullet head 1111 in the central rod to reset and complete the closing of the umbrella.
[0027] The improvement of this invention is that the reset device has a lifting block 4 and a hook block 5. The lifting block 4 is installed on the pressure plate 2 and exposed outside the pressure plate 2 in a way that allows it to move up and down. The pressure plate 2 and the lifting block 4 are provided with a lifting and restoring force generating mechanism that generates an upward restoring force as the lifting block 4 moves down. Specifically, the pressure plate 2 is a strip-shaped arc plate extending in the vertical direction. The rear side of the pressure plate 2 is recessed with a vertically penetrating rear lifting groove 200. The bottom of the upper end of the rear lifting groove 200 is recessed forward to provide a passage to the pressure plate. The front lifting groove 300, which is strip-shaped and extends vertically and runs through the front and back of the top surface of the plate 2, is slidably installed in the upper end of the front lifting groove 300. The lifting restoring force generating mechanism is vertically limited between the lower groove wall of the front lifting groove 300 and the front end of the lifting block 4. The rear part of the lifting block 4 is vertically installed in the rear lifting groove 200. That is, the lifting block 4 has a front lifting part 41 and a rear lifting part 42, both of which are strip-shaped blocks extending vertically. The front lifting part 41 is erected in the upper end of the front lifting groove 300. Guide strips 21 extending vertically are protruding from the left and right inner walls of the front lifting groove 300. The two guide strips 21 are arranged opposite each other, and anti-detachment blocks 211 protrude from the upper front sides of the two guide strips 21 to prevent the front lifting part 41 from detaching from the front lifting groove 300. Guide grooves 400 for the guide strips 21 to extend into are recessed on the left and right sides of the front lifting part 41. The guide grooves 400 extend vertically through the front lifting part 41. The bottom surface of the front lifting part 41 is recessed. An embedding groove 500 is provided. An embedding block 22, opposite to the embedding groove 500, protrudes upward from the inner bottom surface of the front lifting groove 300. The lifting restoring force generating mechanism is a lifting spring (not shown in the figure). The lifting spring is vertically positioned, with its upper end embedded in the embedding groove 500. The embedding block 22 extends into the lower end of the lifting spring. The rear lifting part 42 is vertically positioned within the rear lifting groove 200, with its top surface flush with the top surface of the pressure plate 2 and its bottom surface flush with the bottom surface of the pressure plate 2. In application, during the compression or release of the lifting spring, the lifting spring can drive the front lifting part 41 to move up and down within the front lifting groove 300, thereby driving the rear lifting part to move up and down within the rear lifting groove 200. Simultaneously, under the action of the anti-detachment block 211, when the lifting spring generates an upward restoring force, it can prevent the lifting block 4 from detaching from the pressure plate 2.
[0028] The lifting block 4 has a support device located inside the base 1 on which the outer umbrella pole 112 rests. The hook block 5 is located below the support device. Specifically, the support device is suspended above the rear end of the lifting block 4. The support device has two support bars 6, both extending in the front-to-back direction and spaced apart in the left-to-right direction on the upper rear side of the rear lifting part 42. The two support bars 6 are below and within the range of the hook structure 3, and there is a movable gap between the bottom surface of the support bars 6 and the top surface of the hook block 5. In application, when the outer umbrella pole 112 moves downward, the bottom surface of the outer umbrella pole presses against the top surface of the support bars 6. At this time, the lifting spring compresses downward, the lifting block 4 moves downward, and the two support bars 6 move downward. When the outer umbrella pole 112 moves upward, the lifting spring releases upward, the lifting block 4 moves upward, and the two support bars 6 move upward. The movable gap provides space for the vertical movement of the support device.
[0029] The hook block 5 is mounted on the base 1 in a way that allows it to move back and forth and is located behind the pressure plate 2. A translational restoring force generating mechanism is installed in the base to generate a forward restoring force as the hook block 5 moves backward. The side of the hook block 5 facing the opening 100 has a limiting block 7 that can extend into the pressing hole of the central rod. Specifically, a partition plate 131 is horizontally arranged inside the lower end of the mounting body 13. The partition plate 131 is suspended above the top surface of the lower base 12. The top surface of the partition plate 131 is recessed with an extension opening for the central rod 111 to extend outward. The extension opening extends vertically and downward to the front side of the partition plate 131. The top surface of the partition plate 131 and the lower base 12 are flush with the inner surface of the mounting body 13. A translation groove 600 is formed between the sides, allowing the hook block 5 to move back and forth within it. A translational restoring force generating mechanism extends along the front-back direction and is located between the rear inner wall of the translation groove 600 and the rear side of the hook block 5. The maximum front-back dimension of the hook block 5 is smaller than the maximum distance in the front-back direction of the translation groove 600. That is, the hook block 5 has a rear hook section 51 and a front pushing section 52. Both the rear hook section 51 and the front pushing section 52 are strip-shaped. The rear hook section 51 extends along the left-right direction, and there are two front pushing sections 52. The two front pushing sections 52 extend along the front-back direction and are located at the left and right ends of the front side of the rear hook section 51, respectively. The front pushing ends 52 and the rear hook section 51 are connected. The hook segment 51 is vertically arranged, and the limiting block 7 is located on the front side of the rear hook segment 51. The top surface of the limiting block 7 has an inclined surface 71 that slopes upward from front to back. There is a translational gap 700 between the rear side of the rear hook segment 51 and the rear inner wall of the translation groove 600. A translational spring (not shown in the figure) extending in the front-back direction is provided in the translational gap 700. This translational spring is a translational restoring force generating mechanism. The front end and rear end of the translational spring are respectively connected to the rear side of the rear hook segment 51 and the rear inner wall of the translation groove 600 through a mounting structure. That is, the rear side of the rear hook segment 51 is recessed with a front groove for the front end of the translational spring to be embedded and connected. The bottom of the front groove protrudes forward and is fitted with a front protrusion 511 that is connected to the front end of the translation spring. The rear inner wall of the translation groove 600 protrudes forward and is fitted with a rear protrusion 132 that is connected to the rear end of the translation spring. The front groove, the front protrusion, and the rear protrusion 132 constitute the above-mentioned mounting structure. A limiting block 521 protrudes to the right from the right side of the front pushing section 52 on the right side. The rear side of the limiting block 521 is an inclined surface that slopes from front to back and then to the left. The rear right inner side of the translation groove 600 is recessed with a limiting opening that extends in the front-rear direction and allows the limiting block 521 to move back and forth within it. The front inner wall of the limiting opening fits against the front side of the limiting block 521. In application, under the action of the translation spring, the hook block can move back and forth within the translation groove 600. The limiting opening and the limiting block 521 facilitate the installation of the hook block 5 within the translation groove 600.
[0030] The lifting block 4 is equipped with a pushing structure that can push the hook block 5 backward as the pressure plate 2 moves backward. Specifically, the pushing structure is located at the lower rear end of the rear lifting part 42, and is positioned on the lower rear end of the lifting block 4, opposite to the two front pushing sections 52. Both sides of the lower rear part of the rear lifting part 42 have protrusions 8 extending backward, and the two protrusions 8 respectively abut against the front sides of the two front pushing sections 52, forming the aforementioned pushing structure. In application, the protrusions 8 extend into the pressing holes of the central rod, and the bottom surface of the protrusions 8 presses against the limiting step surface of the umbrella bullet head. Pressing the pressure plate 2 backward compresses the translation spring, causing the hook block 5 to move backward. The protrusions 8 move backward, moving away from the limiting step surface of the umbrella bullet head, and the umbrella bullet head 1111 returns to its original position, completing the opening of the umbrella.
[0031] In this novel automatic umbrella mounting base, when the umbrella is closed, the outer umbrella rod 112 moves downward, and its bottom presses against the top surface of the two support bars 6. The lifting block 4 moves downward, the lifting spring is compressed, and the pushing structure is offset vertically from the front side of the hook block 5 to prevent accidental contact with the hook block 5. The first time the pressure plate 2 is pressed backward, the hook rod structure 3 moves backward and disengages from the outer umbrella rod, and the outer umbrella rod moves upward, thus opening the umbrella. At this time, the limiting block 7 restricts the umbrella bullet head 1111, the lifting block 4 moves upward, and the lifting spring... Release, push the structure and hook block 5 to be set up opposite each other, press the pressure plate 2 backward again, push the structure to press the hook block 5 backward, the hook block 5 moves backward, the limit block 7 moves backward and disengages from the pressing hole of the middle rod 111, the umbrella bullet head resets, and the umbrella is closed; push the outer umbrella rod 112 down, the locking hole of the outer umbrella rod 112 and the hook rod structure hook together, the bottom surface of the outer umbrella rod 112 presses against the top surface of the two support bars 6, the push structure and the front side of the hook block 5 are staggered, and the umbrella is closed. Compared with existing technologies, when the outer umbrella pole and the hook rod structure are hooked together, the outer umbrella pole presses against the top surface of the support device. The downward pressure of the outer umbrella pole acts on the support device and not on the limiting block 7 used to press into the middle rod. This prevents the downward pressure of the outer umbrella pole from damaging the limiting block 7. Furthermore, the support device is installed on the pressure plate 2. Even if damage occurs, only the lifting mechanism needs to be replaced, without disassembling and replacing the entire mounting base, resulting in lower maintenance costs in the later stages.
[0032] In this novel invention, the hook structure 3 is positioned above the support device. The hook structure 3 includes a mounting block 31, a U-shaped piece 32, and an elastic element 33. The mounting block 31 has a U-shaped structure with its front side open, and its front side is integrally injection molded with the upper rear side of the pressure plate 2. The inner wall of the seat 1 has a recessed movable groove 800 that communicates with the hollow cavity of the seat 1 and extends to the outer front side of the seat 1. The mounting block 31 is embedded in the movable groove 800 in a way that allows it to move back and forth via the elastic element 33. The installation method of the elastic element 33 is similar to that of a translation spring. Furthermore, the mounting block 31 and the seat 1... A limiting structure is provided to prevent the mounting block 31 from completely sliding out of the movable groove 800. Specifically, both sides of the mounting block 31 have protruding limiting strips 311 extending vertically. The front side of the limiting strips is an inwardly inclined surface from front to back. The rear sides of the movable groove 800 have recessed limiting grooves 900 extending longitudinally and reaching the rear side of the base 1. A partition block is formed between the two limiting grooves 900. The rear end of the elastic element 33 is connected to the partition block for limiting. A limiting step surface 133 is formed between the bottom of the two limiting grooves 900 and the inner wall of the movable groove 800. The limiting strips 311 are in the limiting position. Within the groove 900, the front side of the limiting strip 311 abuts against the limiting step surface 133, and the limiting strip 311 and the limiting groove 900 constitute the aforementioned limiting structure; the elastic element 33 extends along the front-rear direction and is disposed between the rear side of the mounting block 31 and the rear inner sidewall of the movable groove 800, and the front end and rear end of the elastic element 33 are respectively limited and connected to the rear side of the mounting block 31 and the rear inner sidewall of the movable groove 800 through the mounting structure. The elastic element 33 is a compression spring. The rear sidewall of the mounting block 31 has a recessed groove, and a front block 312 for embedding the front end of the compression spring is protruding in the groove. The rear inner sidewall of the movable groove 800 has a protruding embedded compression spring. The rear block, groove, front block, and rear block of the compression spring constitute the mounting structure of the elastic element 33. The mounting structure of the elastic element 33 is similar to that of the translation spring, and will not be described in detail here. The top surface of the mounting block 31 is recessed with a slot that communicates with the hollow cavity of the mounting block 31. The U-shaped piece 32 is embedded and confined within the slot. The front inner sidewall of the U-shaped piece 32 protrudes forward with a locking block 321 that can extend into the pressing hole of the central rod. The rear sidewall of the U-shaped piece 32 protrudes backward with an inserting block 322. The top surface of the mounting block 31 is recessed at the position of the inserting block 322 with an inserting groove for the inserting block 322 to be inserted. During assembly, the front end of the compression spring is first embedded in the front block 312, and the mounting block 322 of the U-shaped piece 32 is correspondingly embedded in the mounting groove, so that the U-shaped piece 32 is embedded in the slot. Then, the mounting block 31 is aligned with the moving groove 800, the rear end of the compression spring is embedded in the rear block, and the limiting strip 311 enters the limiting groove 900. When the mounting block 31 moves back and forth, under the action of the limiting strip 311, the entire hook structure 3 is not easy to detach from the base 1.In application, pressing the pressure plate 2 backward causes the mounting block 31, which is integrally formed with the pressure plate 2, to move backward as well. This compresses the translation spring, and the U-shaped piece 32, embedded in the top surface of the mounting block 31, also moves backward. This, in turn, causes the locking block 321 to move backward, disengaging it from the locking hole of the outer umbrella rod, thus opening the umbrella. Compared with existing technologies, the mounting block 31 ensures that the locking block 321 moves back and forth when the pressure plate 2 moves forward and backward. It also allows for a larger contact space between the elastic element and the mounting block 31, and the mounting structure prevents the elastic element from shifting. Furthermore, the U-shaped piece 32 can accurately reset after moving back and forth.
[0033] In this invention, preferably, the bottom surface of the rear lifting part 42 is recessed with a dividing groove extending in the vertical direction. The dividing groove divides the lower end of the rear lifting part 42 into two vertically arranged rods. The protrusion 8 is disposed on the lower rear end of the vertical rod, and the bottom of the rear lifting groove 200 is provided with two guide protrusions 23 protruding rearward. The two protrusions 8 are located between the two guide protrusions 23, and the right side of the guide protrusion 23 on the right side is in contact with the left side of the protrusion 8 on the right side, and the left side of the guide protrusion 23 on the left side is in contact with the right side of the protrusion 8 on the left side. In application, when the rear lifting part 42 moves up and down, the arrangement of the two guide protrusions 23 makes it less likely for the rear lifting part 42 to deviate from the rear lifting groove 200.
