Description

Technical Field

[0001] This utility model relates to the field of guide rails, and in particular to a multi-stop sunshade curtain guide rail structure. Background Technology

[0002] Currently, engineering vehicles, represented by cranes, need to travel on roads and perform hoisting operations. Operators need to stay in the control room for long periods of time, and the control room requires a high degree of visibility, with all four sides of glass allowing light to pass through, making sunshades essential.

[0003] Existing sunshades automatically retract after the outer shell is pulled out, and there are two main types of hanging methods:

[0004] (1) Using guide rod friction limit, the two ends of the sunshade curtain pull rod are designed with two rubber rings, which are fitted onto a long rod. When the sunshade curtain is pulled forward, the angle is slightly rotated downward, and the friction is small at this time. When the sunshade curtain needs to be locked, the front pull plate is released. At this time, the rubber ring and the surface of the guide rod generate a large friction force, thus achieving the limit effect of stopping and starting at will.

[0005] However, using guide rod friction limiters has proven to be prone to failure and loosening due to the reliance on rubber ring friction, poor material shock resistance, and the friction force being greatly affected by vibration.

[0006] (2) Using fixed hooks for limiting, the shading area can only be adjusted according to two gears, either full shading or half shading, and multiple limit blocks are required for installation.

[0007] However, the rebound is unguided and has a large retraction force, so if it slips out of your hand, it may cause minor injuries to your hand or head.

[0008] Therefore, it is necessary to develop a new type of sunshade curtain hanging structure to overcome the problems of existing technologies that use guide rod friction limit and fixed hook limit. Utility Model Content

[0009] Purpose of the utility model: In view of the shortcomings and defects of the existing technology, this utility model provides a multi-stop sunshade curtain guide rail structure, which uses hooks to limit the position and avoids the failure of the sunshade curtain locking mechanism; the guide rail can prevent the pull rod from falling off the track and facilitate users to hang and retrieve it.

[0010] Technical solution: The present invention provides a multi-stop sunshade curtain guide rail structure, characterized in that: it includes several sets of hooks, with adjacent sets of hooks equally spaced on the inner side of the guide rail, and the hooks correspond to the sunshade curtain hanging rods inside and outside the sunshade curtain body; the guide rail is provided with guide rail mounting holes at both ends.

[0011] The hook is L-shaped.

[0012] The hook is embedded inside the guide rail.

[0013] The guide rails include a right guide rail and a left guide rail, which are arranged symmetrically side by side.

[0014] The side of the sunshade curtain body is connected to the sunshade curtain retractor.

[0015] The sunshade curtain hanging rod is mounted on a hook, and the sunshade curtain hanging rod is set horizontally.

[0016] The guide rail is mounted in the crane operator's cab via a bracket.

[0017] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: The present invention adopts a guide rail structure with stop hooks distributed at certain intervals on the guide rail, which avoids occupying space and is suitable for double-layer sunshade curtains; the hook form of limiting is stable and reliable, avoiding the situation where the sunshade curtain lock fails due to unreliable friction limiting under the vibration of the whole machine; the guide rail form prevents rebound and hand injury, and the multi-stop hook design allows for flexible selection of the sunshade area.

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] The sunshade curtain of this utility model refers to a device used to effectively block direct sunlight within a passenger space. The guide rail is a track that provides guidance and restricts the movement of moving parts in a specified direction.

[0024] This utility model relates to a multi-position sunshade curtain guide rail structure, comprising several sets of hooks 1, with adjacent sets of hooks 1 evenly spaced on the inner side of the guide rail. The hooks 1 correspond to the sunshade curtain hanging rods inside and outside the sunshade curtain body 5. Guide rail mounting holes 2 are provided at both ends of the guide rail. The hooks 1 are L-shaped and are embedded inside the guide rail. The guide rail includes a right guide rail 3 and a left guide rail 4, which are symmetrically arranged side-by-side. The side of the sunshade curtain body 5 is connected to a sunshade curtain retractor 6. The sunshade curtain hanging rods are secured to the hooks 1 and are horizontally positioned. The guide rail is installed in the crane control room via a bracket.

[0025] This utility model discloses a horizontal guide rail structure for hanging sunshade curtain rods. Made entirely of alloy, it includes multiple sets of hooks evenly distributed at intervals on the inner side of the guide rail, allowing for more adjustable positions. These hooks, arranged at intervals on a single guide rail, correspond to the inner and outer sunshade curtain rods of a double-layered sunshade curtain. The design employs an embedded hook system within the guide rail, with multiple pairs of hooks arranged. This patented solution mainly includes a double guide rail structure, symmetrically designed, mounted on the left and right sides of the control room interior via brackets. Hook 1 is an L-shaped hook, hook 2 is the mounting hole for the guide rail, hooks 3 and 4 correspond to one side of the guide rail respectively, and hook 5 is the sunshade curtain body. After being pulled out from the sunshade curtain retractor (hook 6), the rod ends of the sunshade curtain are engaged with the L-shaped hooks in hook 1, stopping parallel and aligned, thus achieving multiple positioning limits for the sunshade curtain.
