Detailed Description

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the embodiments will be briefly described below. It is obvious that the drawings in the following description are only some embodiments of the invention, and that for a person skilled in the art, other drawings can be derived from them without inventive effort.

In describing embodiments of the present invention, the terms "longitudinal," "lateral," "up," "down," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and other terms are used in an orientation or positional relationship shown in the associated drawings for convenience in describing the invention and for simplicity in description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and are not to be construed as limiting the invention.

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments, which are not repeated herein, but the present invention is not limited to the following embodiments.

Fig. 1 schematically shows a part of a seal according to an embodiment of the invention. The utility model discloses a sealing member is confined loop forming element, and the shape of every cross section is the same in the loop forming element. For clarity, fig. 1 shows only a section or portion of the annular seal and shows this portion as a straight section. In practice, each portion of the annular seal may be curved to a certain degree of curvature. According to the utility model discloses an annular sealing member mainly used gate among the irrigation and water conservancy facility and the sealing between the frame of complex and the base of frame and supporting frame with it. Fig. 2 is a cross-sectional view schematically showing a sealing member according to an embodiment of the present invention.

As can be seen from fig. 1 and 2, the seal comprises an abutment 1, a connecting portion 2 and two water stop strips 3, which are all shaped as coaxial rings. The cross-section of the seal is substantially in the shape of the Chinese character 'dry'. The connecting portion 2 is connected to the abutting portion 1 perpendicularly based on the abutting portion 1 and extends in a direction away from the abutting portion 1. The two water stop strips 3 extend perpendicularly to the connecting portion 2 in directions away from each other on the basis of the connecting portion 2. The sealing strip 3 is then responsible for the main bearing, since the sealing element cooperates with the clamping groove of the frame 4 (see fig. 4), so that the sealing element cannot disengage. And the length of sealing rod 3 is short then to lean on intensity with the holding of draw-in groove and is low excessively, and length overlength then is difficult for inserting the sealing member in the draw-in groove, consequently the utility model discloses a sealing rod 3's both ends and top are leaned on portion 1 and are controlled both ends (whole loop forming element ring width direction promptly) and flush in figure 2, and most laborsaving when guaranteeing to peg graft, and have sufficient holding and lean on intensity. In the present embodiment, the water stop strip 3 has a rectangular cross section. And, the cross section of the connection part 2 is rectangular. The cross-sectional shape of the connecting part 2 is not necessarily rectangular, but may be, for example, square or other shapes according to different use conditions. The portion of the connecting portion 2 between the abutting portion 1 and the water stop 3 may not be a continuous, closed annular support portion, but may be a connecting rib or a reinforcing rib (i.e., support portions provided at intervals) provided between the abutting portion 1 and the water stop 3. This portion does not provide a sealing function by itself, but merely integrally interconnects the backrest 1 and the water stop strip 3. The part of the connecting portion 2 on the other side of the water stop 3 is required to provide a sealing function, and therefore the free end face thereof must be a continuous annular surface.

In the installation and use state, the free end surface of the connecting part 2, the water stop strip 3 and the surface of the abutting part 1 corresponding to the free end of the connecting part 2 are sealing surfaces and abut against the inner side and the outer side of the frame 4 respectively to realize the sealing function. As can be seen from the above-described structure of the sealing member according to the present invention, such a sealing member has a sealing surface on a cross section. Thereby creating multiple sealing effects of one seal. An independent seal is formed at the free end face of the connecting part 2, and a labyrinth seal is formed between two water stop strips 3 extending from the connecting part 2 and the sealing surface of the abutting part 1 adjacent to the water stop strips. With this structure, the seal provides reliable sealing performance. Furthermore, the abutment 1 is the main part of the overall seal, providing rigidity and strength to the seal, while the connecting part 2 is primarily intended to provide support for the two water stop strips 3 and a sealing surface on the front or free end face thereof.

Fig. 2 shows an embodiment of a cross section of a seal according to the invention. In this embodiment, the long side of the cross section of the abutting portion 1 is 8mm (dimension a in fig. 2), and the wide side is 5mm (dimension b in fig. 2). The cross-sectional broadside dimension of the connecting portion 2 is 4mm (dimension d in fig. 2). The distance from the end face of the connecting part 2 away from the abutting part 1 to the water stop strip 3 is 6mm (dimension c in fig. 2). The water stop 3 has a cross-sectional width dimension of 1.5mm (dimension f in fig. 2). The dimension from the upper end surface of the connecting portion 2 to the lower end surface of the abutting portion 1 is 14.5mm (dimension e in fig. 2).

Fig. 3 is a front view of a flat gate incorporating a seal according to an embodiment of the present invention. Fig. 3 shows that the flat lock gate includes a base 6, a frame 4 supported on the base 6, and a gate 5 slidable up and down in the frame 4. The sealing element of the present invention is installed on the frame 4, and is respectively located at two positions (i.e. the inner and outer sides of the frame 4), and the specific matching manner with the frame 4 is shown in fig. 4. Utilize the utility model discloses a during the sealing member, the inside and outside both sides of frame 4 all need be equipped with the connecting portion 2 of shape and sealing member and 3 shape complex draw-in grooves of stagnant water strip, and the sealing member can form the draw-in groove cooperation with frame 4 when the installation. Most sealing members need special pressing plates to be installed on the frame 4 in the prior art, and the utility model discloses a sealing member is equipped with two sealing strips 3, consequently need not the pressing plate also can block in the draw-in groove of frame 4 when using, and it is very convenient to install. And the sealing member is the integral annular structure, need not hot melt bonding when the installation to make the sealing member do not have the seam, not fragile, this kind of mode is more environmental protection moreover. To sum up, the utility model discloses a sealing member simple structure, processing is convenient. In addition, a special die is not needed for producing the pressing plate, so that the installation cost is effectively reduced, and the manufacturing cost is saved.

The utility model discloses a when the inboard on the frame was installed to the sealing member in frame 4 (be B position), connecting portion 2 was outwards, and when installing in the outside of frame 4 (be A position), connecting portion 2 was inwards. Two rubber materials's sealing member install back on frame 4 as above-mentioned mode, form the extrusion with gate 5 and base 6 respectively to can form the quintuple surface of water with the draw-in groove of frame 4, the difficult seepage phenomenon that takes place has good stagnant water effect.

The above description is only one embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
