Description

Technical Field

[0001] This utility model belongs to the field of sunshade umbrella technology and relates to a handrail shell for a sunshade umbrella. Background Technology

[0002] Sun umbrellas are everyday items used for sun protection, commonly found in courtyards, public places, and other rest areas. As people's living standards continue to improve, the use of sun umbrellas is becoming increasingly widespread, providing people with a more comfortable leisure environment. The armrest shell is an important component of a sun umbrella, housing both the locking mechanism and the cord retraction mechanism.

[0003] Patent application number CN202410301682.3 discloses a handrail shell structure for an outdoor umbrella. The outdoor umbrella includes a pillar, and the handrail shell structure includes a shell slidably connected to the pillar. The shell includes a left half shell and a right half shell that are interlocked and fixed together. Both the left half shell and the right half shell protrude to form an annular mounting ring. It also includes two interlocking connecting half shells that can be fixed together with a diagonal rod. The connecting half shell includes an annular rotating ring that is arranged one-to-one with the mounting ring. The rotating ring is sleeved on the corresponding mounting ring and rotates along the mounting ring. A hand crank assembly is rotatably connected to the shell, and the hand crank assembly is located in the inner space of the mounting ring.

[0004] The above-mentioned handrail shell structure still has shortcomings: the handrail shell is locked to the upright by a horizontally extended pin. During use, the pin needs to bear a large load vertically. The snap-fit ​​seam of the handrail shell is exactly opposite to the vertical pin. This makes the structure of the left and right halves of the shell at the pin easy to deform after a period of use, which affects the movement of the pin. Summary of the Invention

[0005] This utility model addresses the aforementioned problems in existing technologies by providing a handrail shell for a sunshade. The technical problem this utility model aims to solve is that the existing handrail shell structure of sunshades is easily deformed by the vertical load of the pin.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A parasol armrest shell includes a left half shell and a right half shell that interlock. The edges of the left half shell and the right half shell have left and right notches, respectively. The left and right notches together form a through hole for a pin to pass through. The left half shell has two support plates integrally formed on its inner side, protruding towards the right half shell. The two support plates are arranged at intervals at the upper and lower edges of the left notch. The right half shell has a positioning groove communicating with the right notch on its inner side. The support plates are all vertically positioned in the positioning groove.

[0008] The interlocking design of the left and right halves facilitates assembly by simply inserting the components and then snapping them together. The left and right notches, when combined, form a through hole for the positioning and passage of the existing pin, allowing the pin to move within the hole to lock and unlock the armrest shell and the pillar. Two spaced-apart support plates are integrally connected to the inside of the left half, positioned at the upper and lower edges of the left notch. A positioning groove is provided on the inside of the right half, vertically positioning the two support plates within it. When the pin passes through the through hole and interacts with the armrest shell, it is directly constrained and supported vertically by the integrated support plate. This provides superior structural stability, reducing deformation under vertical stress. Furthermore, the outer side of the support plate is further constrained by the inner wall of the positioning groove, preventing deformation. This ensures the interlocking structure of the left and right halves maintains sufficient structural strength at the pin shaft, guaranteeing stable pin movement.

[0009] In the armrest shell of the aforementioned sunshade, the outer ends of both support plates abut against the bottom surface of the positioning groove. This ensures that after the left and right halves of the shell are engaged, the outer ends of the support plates are constrained by the bottom surface of the positioning groove, compressing the potential deformation space of the support plates and thus ensuring structural stability.

[0010] In the armrest shell of the aforementioned sunshade, the through hole is circular, and the bottom surface of the positioning groove has an arc-shaped positioning surface. The cross-sectional shape of the positioning surface matches the shape of the right notch. The circular through hole is compatible with commonly used cylindrical pins, which helps to create a certain positioning constraint effect on the outer periphery of the pin, making the position and direction of the pin more stable during axial movement and reducing the phenomenon of off-center loading caused by pin misalignment.

[0011] In the armrest shell of the aforementioned sunshade umbrella, the left and right halves of the shell each have vertically arranged elongated left and right sliding strips, respectively. These left and right sliding strips are abutted against each other in the left-right direction. The left and right notches are located in the middle sections of the left and right sliding strips, respectively. Both the left and right sliding strips have coaxially arranged, through-hole mounting holes. This abutment of the left and right sliding strips, along with the connecting piece passing through the mounting holes, secures the sliding component to the frame, facilitating a stable sliding fit with the existing support column and making the armrest shell more stable and reliable during its up-and-down movement along the column.

[0012] In the armrest shell of the aforementioned sunshade, both the upper and lower ends of the left slide bar have annular bosses protruding towards the right slide bar. The mounting hole extends through to the end face of the annular boss. The mounting hole on the right slide bar is a stepped hole, and the annular boss is positioned and inserted into the mounting hole on the right slide bar. In this way, the annular bosses at both the upper and lower ends of the left slide bar and the mounting holes of the right slide bar form a vertical positioning. While achieving fixed installation, it can also provide external protection and vertical positioning reinforcement for the insertion relationship between the support plate located in the middle section and the positioning groove, ensuring a stable and reliable fit between the support plate and the positioning groove.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] During use, the handle shell of this sunshade allows the pin to be directly constrained and supported by the integrated structural support plate in the vertical direction. The support plate has better structural stability, and when the support plate is under force, its outer side can also be constrained and supported by the inner wall of the positioning groove, which prevents the support plate from deforming after being subjected to vertical load. This ensures that the interlocking structure of the left and right half shells maintains sufficient structural strength at the pin shaft, which helps to ensure the stable and reliable shape of the through hole and allows the pin to move smoothly without deflection.

[0022] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0023] like Figure 1 , Figure 2 As shown, the armrest shell of this sunshade includes a left half shell 1 and a right half shell 2 that interlock. Both the left half shell 1 and the right half shell 2 are injection molded parts. The edges of the left half shell 1 and the right half shell 2 have left notches 11 and right notches 21, respectively. The left notches 11 and right notches 21 together form a through hole 3 for the pin to pass through. The through hole 3 is circular. The edges of the left half shell 1 and the right half shell 2 have vertically arranged elongated left slides 13 and right slides 24, respectively. The left slides 13 and right slides 24 are close to each other in the left-right direction. The left notches 11 and right notches 21 are located in the middle sections of the left slides 13 and right slides 24, respectively. Both the left slides 13 and right slides 24 have coaxially arranged and through mounting holes 4.

[0024] like Figure 2 , Figure 3 As shown, the inner side of the left half shell 1 has two support plates 12 integrally formed protruding towards the right half shell 2. The two support plates 12 are arranged at intervals at the upper and lower edges of the left notch 11. The left slide bar 13 has annular bosses 14 protruding towards the right slide bar 24 at both the upper and lower ends. The mounting hole 4 extends through to the end face of the annular bosses 14.

[0025] like Figure 4 As shown, the inner side of the right half shell 2 has a positioning groove 22 that communicates with the right notch 21. The bottom surface of the positioning groove 22 has an arc-shaped positioning surface 23, and the cross-sectional shape of the positioning surface 23 is adapted to the shape of the right notch 21. The mounting hole 4 on the right slide bar 24 is a stepped hole with the larger end facing inward.

[0026] like Figure 5 , Figure 6 As shown, the support plates 12 are both vertically positioned within the positioning grooves 22, and the outer ends of both support plates 12 abut against the bottom surface of the positioning grooves 22. The annular boss 14 is positioned and inserted into the mounting hole on the right slide bar 24.

[0027] After the left half shell 1 and the right half shell 2 are fastened together, the pin inserted into the through hole 3 is constrained by the two support plates 12 on its upper and lower sides respectively. The support plate 12 and the left half shell 1 are an integral structure, so that the position where the support plate 12 contacts the pin is a complete structure with better support strength, so that the through hole 3 for the axial movement of the pin can maintain a stable shape and avoid the pin from tilting.
