Abstract

This Innovation Patent is a kind of spring limit clamp which is mainly composed of body of the spring. A limit clamp is arranged between the upper leaf and the lower leaf. The limit clamp includes a top plate and a bottom plate. A vertical bar is arranged between the top plate and the bottom plate. The top plate, bottom plate and vertical bar are shaped as a jOCi±. The vertical bar is separated in the middle, with a buckle at the separation position. A lug with its diameter greater than that of the vertical bar is arranged at the tail end of the vertical bar. A plug-in piece is arranged at the connection right angle between the top plate and the vertical bar. This Innovation Patent is mainly used in some important sites. A limit clamp is arranged between upper and lower springs. When the spring is dragged to a limiting position, the limit clamp can be used to restrict the spring to be stretched again, so as to guarantee service life of the spring and normal operation of the equipment, increase safety and reduce costs.

Description

EDITORIAL NOTE 2014100686 There are two pages of description only Spring Limit Clamp Technical Field This Innovation Patent is a kind of spring limit clamp. Background Technology Generally, spring is used for shock absorption or in some important stretching machines. As each spring has an ultimate tensile position, it is easy to deform after being used for a long period. After exceeding ultimate tension of the spring, it will be permanently deformed, resulting in an effect on normal use of the spring and increase of maintenance costs. Description on the Invention The technical issue to be solved by this Innovation Patent is to provide a spring limit clamp which can limit the spring to be stretched again, so as to guarantee service life of the spring and normal operation of the equipment, increase safety and reduce costs. This Innovation Patent is realized through the following technical plan: a kind of spring limit clamp including body of the spring. A limit clamp is arranged between the upper leaf and the lower leaf. The limit clamp includes a top plate and a bottom plate. A vertical bar is arranged between the top plate and the bottom plate. The top plate, bottom plate and vertical bar are shaped as a jOCi±. The vertical bar is separated in the middle, with a buckle at the separation position. A lug with its diameter greater than that of the vertical bar is arranged at the tail end of the vertical bar. A plug-in piece is arranged at the connection right angle between the top plate and the vertical bar. As an optimized technical plan, the said plug-in piece is shaped as an jOLi±. The cross plate is arranged in the top plate, and the vertical bar and side wall of the spring are arranged in contact with each other. As an optimized technical plan, the said buckle is shaped as a Chinese letter jiOj i±, with openings at upper and lower ends. Internal diameter of the buckle is greater than that of upper and lower openings. As an optimized technical plan, magnet sheet is arranged at the contact surface of the top plate, bottom plate and lower & upper springs. Beneficial effects of the spring limit clamp are described as follows: this Innovation Patent is mainly used in some important sites. A limit clamp is arranged between upper and lower springs. When the spring is dragged to a limiting position, the limit clamp can be used to restrict the spring to be stretched again, so as to guarantee service life of the spring and normal operation of the equipment, increase safety and reduce costs. Description on the Attached Figure In order to interpret in an easier way, this Innovation Patent is described in details with the following specific implementation mode and attached figure. Fig. 1 shows the structural representation of this Innovation Patent. Specific Implementation Mode As shown in Fig. 1, the spring limit clamp includes body of the spring. A limit clamp is arranged between the upper leaf (1) and the lower leaf (7). The limit clamp includes a top plate (2) and a bottom plate (3). A vertical bar (5) is arranged between the top plate (2) and the bottom plate (3). The top plate (2), bottom plate (3) and vertical bar (5) are shaped as a jOCi±. The vertical bar (5) is separated in the middle, with a buckle (8) at the separation position. A lug (6) with its diameter greater than that of the vertical bar (5) is arranged at the tail end of the vertical bar (5). A plug-in piece (4) is arranged at the connection right angle between the top plate (2) and the vertical bar (5). As an optimized implementation mode, the said plug-in piece (4) is shaped as an jOLi±. The cross plate is arranged in the top plate (2), and the vertical bar and side wall of the spring are arranged in contact with each other, so as to prevent the limit clamp and the spring from sliding. In this implementation case, the buckle (8) is shaped as a Chinese letter jiOj i±, with openings at upper and lower ends. Internal diameter of the buckle is greater than that of upper and lower openings. When the spring is dragged to the limit position, lug of the vertical bar will block at upper and lower openings of the buckle to prevent the vertical bar from pulling out of the buckle. As an optimized technical plan, magnet sheet is arranged at the contact surface of the top plate, bottom plate and lower & upper springs to increase the contact strength between the limit clamp and the spring. Beneficial effects of the spring limit clamp are described as follows: this Innovation Patent is mainly used in some important sites. A limit clamp is arranged between upper and lower springs. When the spring is dragged to a limiting position, the limit clamp can be used to restrict the spring to be stretched again, so as to guarantee service life of the spring and normal operation of the equipment, increase safety and reduce costs. Above paragraphs are only about the specific implementation mode of this Innovation Patent. However, the scope of protection of this Innovation Patent is not limited to this description. Any change or replacement without creative work should be covered in the scope of protection of this Innovation Patent. Therefore, the scope of protection defined in the Claims prevails for that of this Innovation Patent.
