Abstract
一种新型叉梯，分别在叉梯的四条腿上安装一个滚轮，叉梯腿金属管直径较大于滚轮直径，滚轮可伸入叉梯腿金属管内。滚轮由一个插入叉梯腿内部的金属杆支撑，在金属杆的中部套有弹簧，弹簧可随金属杆的上下移动伸缩，弹簧上端和下端被固定。在弹簧中部的位置，叉梯腿表面有一可旋进旋出叉梯腿金属管的螺丝，螺丝长度较长于弹簧直径，旋进可插入弹簧间隔。该新型叉梯通过滚轮实现叉梯移动，节省体力，方便快捷，提高了工作效率，降低了劳动强度。
The utility model relates to a new type of fork ladder. A roller is respectively installed on four legs of the fork ladder. The diameter of the metal pipe of the fork ladder leg is larger than that of the roller, and the roller can extend into the metal pipe of the fork ladder leg. The roller is supported by a metal rod inserted into the legs of the fork ladder. A spring is sheathed in the middle of the metal rod. The spring can expand and contract as the metal rod moves up and down, and the upper and lower ends of the spring are fixed. In the middle of the spring, there is a screw on the surface of the fork ladder leg that can be screwed in and out of the metal tube of the fork ladder leg. The length of the screw is longer than the diameter of the spring, and the screw can be inserted into the spring gap. The new type of fork ladder realizes the movement of the fork ladder through the rollers, saves physical strength, is convenient and quick, improves work efficiency and reduces labor intensity.
Description
Technical field
The utility model relates to a kind of Novel fork ladder, specifically is exactly a kind of fork ladder of convenient mobile carrying.
Background technology
Along with socioeconomic development, people pursue conveniently daily necessities more.The terraced generally use that obtains many workmans among life of fork increase the stability that the terraced quality of fork can effectively improve ladder, but quality is too large, is not easy to carrying and moves, and has brought inconvenience and trouble to people, has reduced efficiency, has increased labour intensity.
Summary of the invention
Be difficult for greatly the mobile problem of carrying in order to solve the terraced quality of existing fork, the utility model provides a kind of Novel fork ladder, realizes that by the spring wheel of pitching terraced bottom the carrying of fork ladder is moved, and has not only saved muscle power but also convenient and swift.
The technical scheme that its technical problem that solves the utility model adopts is: at four legs of fork ladder a roller is installed respectively, is pitched terraced leg metal tube diameter greater than roller diameter, roller can stretch in the terraced leg metal tube of fork.Roller is supported by a Metallic rod of inserting the terraced leg of fork inside, and cover has spring at the middle part of Metallic rod, and spring can be flexible with moving up and down of Metallic rod, and the spring top and bottom are fixed.Position at the spring middle part has spinning in and out to pitch the screw of terraced leg metal tube but pitch terraced leg surface, and screw length is longer than spring diameter, and precession can be inserted the spring interval.
The beneficial effects of the utility model are: this Novel fork ladder realizes that by roller the fork ladder is mobile, saves muscle power, and is convenient and swift, improved operating efficiency, reduced labour intensity.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Structure chart when Fig. 1 is the workman working roller is compressed on the fork ladder.
Fig. 2 is unmanned structure chart when pitching terraced upper roller without compression.
Among the figure: 1, the terraced leg metal tube of fork, 2, Metallic rod, 3, spring, 4, roller, 5, screw.
The specific embodiment
When the workman climbs up the fork ladder, pitch the roller 4 of terraced leg bottom owing to workman's pressure, Compress Spring 3 enters the terraced leg metal tube 1 of fork, and precession screw 5 blocks spring 3, prevents from moving up and down.When the workman gets off, screw out screw 5, roller stretches out the terraced leg metal tube 1 of fork under the pressure of spring, can carry movement.
Claims (3)
1. Novel fork ladder is characterized in that: at four legs of fork ladder rollers (4) are installed respectively, are pitched terraced leg metal tube (1) diameter greater than roller (4) diameter, roller (4) can stretch in the terraced leg metal tube of fork (1).
2. Novel fork according to claim 1 is terraced, it is characterized in that: roller (4) is supported by a Metallic rod (2) of inserting the terraced leg of fork inside, cover has spring (3) at the middle part of Metallic rod, spring (3) can be flexible with moving up and down of Metallic rod (2), and spring (3) top and bottom are fixed.
3. Novel fork according to claim 1 is terraced, it is characterized in that: the position at spring (3) middle part, but pitching terraced leg surface has spinning in and out to pitch the screw (5) of terraced leg metal tube (1), screw (5) length is longer than spring (3) diameter, and precession can be inserted spring (3) interval.
