Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

The preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

Aiming at the problem that the sealing strip is easy to fall off in the prior art, one measure for improving the problem is to fix the sealing strip by glue. Increase glue through the position that contacts at installed part and sealing strip promptly and glue glutinous to make the connection between installed part and the sealing strip more firm, and then reach the problem of solving the sealing strip and easily droing. However, in such a solution, it is not easy to apply glue at the contact position between the mounting member and the sealing strip, and although this can be achieved by filling the glue into the open slot, the amount of glue required is relatively large.

The inventor researches and discovers that the convex part matched with the sealing strip is arranged on the side wall of the open slot by changing the structures of the mounting part and the sealing strip, so that the convex part can block the open slot from being pulled out by the sealing strip, and further the sealing strip can be prevented from falling off.

The application provides a sealing strip anti-disengaging structure can be applied to different technical field, and especially, this application is applied to this structure with floor cleaning machine or scrubber for example ground cleaning equipment.

As shown in fig. 1 and 2, a sealing strip separation prevention structure 100 for one embodiment of the present application includes a mounting member 110. The mounting member 110 has a mating face 113 for mating with the mating member 101, the mating face 113 being partially recessed to form an open slot 111 for mounting the sealing strip 120. The side wall of the open groove 111 is provided with a convex portion 112 that protrudes toward the inside of the open groove 111.

It is understood that the material of the mounting member 110 may be selected according to the field to which the weatherstrip shedding prevention structure 100 is applied.

As shown in fig. 2, the opening groove 111 is opened on the surface of the mounting member 110 connected to the sealing strip 120 and is recessed in the surface. Optionally, the sealing strip 120 is in a closed ring structure, located on the side of the mounting member 110 connected to the other component, and surrounds the connecting area of the mounting member 110 and the other component to achieve a sealing effect. Since the opening groove 111 is used for mounting the sealing strip 120, the opening groove 111 is formed annularly on the surface of the mounting member 110.

In the above scheme, the convex portion 112 is arranged on the side wall of the opening groove 111, and the convex portion 112 is located inside the opening groove 111, so that the opening groove 111 is pulled out of the sealing strip 120 to cause obstruction, the effect of preventing the sealing strip 120 from falling is achieved, and the problem that the sealing strip 120 is easy to fall in the prior art is solved.

In the present embodiment, the projection 112 is formed in a ring shape, and a cross section of the projection 112 is shown in the drawing.

It should be noted that the protrusion 112 protrudes from the sidewall of the open groove 111 toward the inside of the open groove 111, and functions to hinder the sealing strip 120 from being pulled out of the open groove 111. The shape of the protrusion 112 may be set to influence the size of the obstruction of the sealing strip 120 from the opening groove 111 to some extent.

As shown in fig. 2, in a specific arrangement, a side of the protrusion 112 near the bottom of the opening groove 111 is an inclined surface 1121. The inclined surface 1121 extends from the side wall of the open groove 111 toward the middle of the open groove 111 in the process of extending toward the opening of the open groove 111.

It is understood that, as shown in fig. 1, the two protrusions 112 may serve as a passage for inserting or extracting the sealing strip 120 into or out of the open groove 111.

It should be noted that the inclined surface 1121 may be an inclined plane as shown in fig. 2 or an inclined arc surface, and the inclined direction thereof may also be expressed as extending from the side wall of the open groove 111 to the middle of the open groove 111 in the process of extending to the opening of the open groove 111.

The arrangement structure of the inclined surface 1121 can prevent the sealing strip 120 from being completely clamped in the opening groove 111 and being unable to be pulled out as far as possible, and can also be used as a demoulding inclined surface, which is convenient for demoulding in the forming process.

It will be appreciated that the protrusion 112 protruding from the sidewall of the open slot 111 can achieve the technical effect of preventing the sealing strip 120 from being pulled out of the open slot 111. In a specific arrangement, referring to fig. 1 and 2, the protrusion 112 is located near the opening end of the open slot 111 (i.e., the end away from the slot bottom).

The convex portion 112 is located at one end close to the opening of the open slot 111, and compared with a scheme that the convex portion 112 is arranged inside the open slot 111, the processing difficulty is lower no matter plastication molding or processing molding is adopted. Particularly, when plasticizing molding is adopted, the mold structure is simpler; when the processing molding is adopted, the processing procedure is more simplified.

Referring to fig. 1, 2, 5 and 6, the weather strip retaining structure 100 is shown disposed in a waste tank (also referred to herein as a tank) of a floor cleaning apparatus such as a sweeper or scrubber. In this embodiment, the weather strip escape prevention structure 100 includes a mounting member 110, specifically a rear cover, and a weather strip 120 interposed between the rear cover and a mating member 101, specifically a vehicle body side wall.

The face defining the mounting member 110 (i.e., the rear cover as shown in fig. 5 and 6) for facing the mating member 101 (i.e., the body side wall as shown in fig. 5 and 6) is a mating face 113 (as shown in fig. 5), and the opening groove 111 is recessed in the mating face 113. It will be appreciated that, in general, the mating surface 113 will contact the mating member 101 and be sealingly connected to the mating member 101 by the sealing strip 120. Thus, the side 1122 of the trough bottom of the distal opening 111 of the boss 112 should not protrude from the mating face 113 so as to interfere with the sealing of the mount 110 with the fitting 101.

In one arrangement, the side 1122 of the protrusion 112 may be slightly recessed from the surface of the mounting member 110 where the slot 111 is located. However, in the present embodiment, as shown in fig. 2, the side surface 1122 of the convex portion 112 is flush with the mating surface 113. With such an arrangement, the convex portion 112 does not affect the sealing between the mounting member 110 and the mating member 101, the processing process can be simplified, the process flow of processing the lower concave surface is not increased, the strength of the convex portion 112 can be ensured, and the convex portion 112 is prevented from being broken when the sealing strip 120 is pulled out of the mounting member 110.

Referring to fig. 1 and 2, in a specific arrangement, the number of the protrusions 112 is two, and the two protrusions are respectively disposed on two opposite sidewalls of the opening groove 111, so that when the sealing strip 120 is installed in the opening groove 111, the two protrusions 112 are respectively disposed on two sides of the sealing strip 120. The number of the protrusions 112 is two, and the protrusions 112 may be two annular strip-shaped protrusions 112 along the sidewall of the open slot 111, or each protrusion 112 may have a gap in the circumferential direction.

It should be noted that the two protrusions 112 may be symmetrically disposed at any height in the opening groove 111 as shown in fig. 2, or may be staggered at different heights in the opening groove 111.

By arranging the two convex parts 112 respectively arranged on the two opposite side walls of the opening groove 111, the stress on the two sides of the sealing strip 120 is more uniform when the sealing strip 120 is installed, and the phenomenon that the whole sealing strip 120 falls off due to the fact that the sealing strip 120 is single-side fallen off in the use process is avoided.

As shown in fig. 2, when the mounting member 110 is a plastic member, rotational molding may be used during manufacturing. The shaped part 200 in the rotational moulding mould of the mounting 110 can be referred to in figure 4. The rotational moulding process is that plastic raw material is added into mould, then the mould rotates along a rotation axis and revolves along another rotation axis continuously to heat the plastic raw material, so that the plastic raw material in the mould is coated, melted and adhered on the whole surface of the mould cavity gradually and uniformly under the action of gravity and heat energy to be moulded into the required shape, and then the product is obtained after cooling, shaping and demoulding. Unlike the conventional rotational molding process, the rotational molding of the mounting member 110 requires opening the mold when the mold and the mounting member 110 are not completely cooled to room temperature, and then cooling the mounting member 110 to room temperature.

Referring to fig. 4, the forming member 200 has a groove therein to match the protrusion of the mounting member 110. In the rotational molding process of the mounting member 110, since the mounting member 110 is not completely cooled and molded during mold opening and a certain plasticity is maintained, the mounting member 110 can be smoothly separated from the molding member 200 without changing the shape of the convex portion 112 of the mounting member 110 during the mold opening process in which the molding member 200 of the mold is separated from the mounting member 110.

As shown in fig. 1 and 3, in a specific arrangement, the sealing strip 120 is further included, and one end of the sealing strip 120 is provided with a mounting portion 121 capable of being inserted into the opening groove 111. The mounting portion 121 includes an inverted tooth 1211 that fits over the protrusion 112.

It will be appreciated that one end of the sealing strip 120 is provided with a mounting portion 121, the other end of which is configured to be adjustable in relation to the configuration of the other component to which the mounting member 110 is connected.

By arranging the inverted tooth 1211, the inverted tooth 1211 is matched with the convex part 112 to form a buckle structure together, so that the sealing strip 120 is blocked from being pulled out of the opening groove 111, and the effect of preventing the sealing strip 120 from falling off is achieved.

In one particular arrangement, the sealing strip 120 is made of a flexible material.

It is understood that the flexible material is a material with a certain softness and flexibility, and in this embodiment, the sealing strip 120 may be made of a rubber material.

By providing the sealing strip 120 with a flexible material, the sealing strip 120 can be smoothly inserted into the opening groove 111 through the convex portion 112, and can be smoothly pulled out from the opening groove 111 through the convex portion 112 in a situation where maintenance is required.

Referring to fig. 3, in a specific arrangement, the sealing strip 120 further includes an insertion head 1212. The inverted teeth 1211 are located on the sidewall of the insertion head 1212 and protrude from the sidewall of the insertion head 1212. The inverted tooth 1211 is disposed obliquely to the insertion head 1212, and the extending direction of the inverted tooth 1211 is inclined from one end of the sidewall near the insertion head 1212 to the other end in the direction along which the sealing strip 120 is inserted into the opening groove 111.

It will be appreciated that the inverted teeth 1211 project from the side walls of the insertion head 1212 such that the inverted teeth 1211 are closer to the side walls of the open slot 111 than the side walls of the insertion head 1212. The pawl 1211 is angled relative to the insertion head 1212 in a direction such that an inclined surface of the pawl 1211 is parallel to the inclined surface 1121 of the projection 112 of the mounting member 110.

By providing the inverted tooth 1211 obliquely, the frictional force between the inverted tooth 1211 and the convex portion 112 of the mounting member 110 can be increased, thereby increasing the resistance to the removal of the sealing tape 120 from the opening groove 111.

Referring to fig. 1 and 3, in a specific arrangement, two symmetrical inclined planes 1213 are provided at the end of the insertion head 1212 abutting against the bottom of the open slot 111. The extension direction of the inclined surface 1213 is inclined from the center line of the insertion head 1212 to both sides in the direction opposite to the direction in which the sealing tape 120 is inserted into the open groove 111.

With reference to fig. 1 and 3, the two inclined surfaces 1213 inclined from the center line of the cross section of the insertion head 1212 to both sides in the opposite direction to the direction in which the sealing strip 120 is inserted into the opening groove 111 form a "V" shaped structure, which can reduce the friction between the sealing strip 120 and the protrusion 112 and the sidewall of the opening groove 111 when the insertion head 1212 is inserted into the opening groove 111, so that the insertion head 1212 can enter the opening groove 111 more easily.

Referring to fig. 1 and 3, in a specific arrangement, the sidewall of the insertion head 1212 is provided with a plurality of slanted bars 1214 that are inclined in the same direction as the slanted surfaces 1213. The slanted bar 1214 abuts against the sidewall of the open slot 111 and is in interference fit with the sidewall of the open slot 111.

As shown in fig. 3, the slanted bar 1214 is parallel to the slanted surface 1213, on one hand, to reduce the friction between the sealing bar 120 and the protrusion 112 and the sidewall of the opening groove 111 when the insertion head 1212 is inserted into the opening groove 111, so that the insertion head 1212 can enter the opening groove 111 more easily, and on the other hand, to facilitate the demolding during the production process. The inclined strips 1214 are abutted against the side walls of the open slot 111 and are in interference fit with the side walls of the open slot 111, so that the friction force between the sealing strip 120 and the mounting piece 110 in the process of pulling the open slot 111 out of the insertion head 1212 is increased, the open slot 111 is pulled out of the sealing strip 120 to be blocked, the effect of preventing the sealing strip 120 from falling off is achieved, and the problem that the sealing strip 120 is prone to falling off in the prior art is solved.

Referring to fig. 5 and 6, a floor cleaning device 10 is shown according to an embodiment of the present application, including a seal strip retaining structure 100 as shown in any one of the above.
