In the embodiment of the utility model, the pressing strip comprises a strip-shaped pressing strip main body 100, at least 2 pressing pieces 200 are connected to the pressing strip main body 100, a connecting piece 300 which can be connected with a frame 400 is arranged on the pressing strip main body 100 or the pressing piece 200, the pressing piece 200 presses the mask 500 under the condition that the connecting piece 300 is connected with the frame 400, so that the mask 500 is pressed on the frame 400, a first side 103 of the pressing piece 200 is contacted with the frame 400, and as the pressing strip main body 100 is a deformable structural member, the shape of the pressing strip main body 100 can be changed by controlling whether the pressing strip main body 100 is deformed or not and controlling the deformation direction and the deformation amount of the pressing strip main body 100, so that the pressing strip main body 100 is matched with frames 400 with various shapes, and the first side 103 is of a micro-arc structure, therefore, the arc length of the first side 103 is short, the first side 103 can be matched with frames 400 with different sizes and even the frames 400 with shapes can be adapted. It can be seen that the first side 103 of the flexible molding body 100 and the first side 103 of the micro-arc structure of the present embodiment can adapt the molding to the frame 400 with various shapes, so as to adapt the molding to the lamp with various shapes.

The layering of this embodiment is adapted to square lamps and lanterns, oval lamps and lanterns, circular lamps and lanterns of different diameters etc.. Taking the round lamp fitting with the batten of the embodiment as an example, four battens can be selected during installation, each batten main body 100 is bent into an arc shape matched with the round lamp fitting, and after the battens are attached to the inner peripheral wall of the frame 400 of the lamp fitting, the connecting piece 300 is connected with the frame 400, so that the pressing piece 200 presses the mask 500. If the lamp is a square lamp, four pressing strips can be selected, and the pressing strips are directly attached to the inner peripheral wall of the frame 400 without bending the pressing strip main body 100. Of course, in the actual installation, one pressing bar, three pressing bars and the like can be selected, and the utility model is not limited to the pressing bars.

In an alternative embodiment, the arc length of the first side 103 is 10mm to 40mm. In this embodiment, the arc length of the first side 103 is greater than 10mm, so that the pressing member 200 has a larger contact area with the mask 500, thereby ensuring that the pressing member 200 stably presses against the mask 500. Further, the radius of the first side 103 is larger than 100mm, which may improve the fit of the first side 103.

To improve the connection stability between the bead and the frame 400, in an alternative embodiment, the pressing member 200 includes a pressing plate 220 and a first inserting protrusion 230, where the first inserting protrusion 230 extends from an edge of the pressing plate 220 toward the first side 101 to form a relatively bent structure with the pressing plate 220, the pressing plate 220 is used to press the mask 500, the pressing plate 220 has a first side 103 and a second side 104, the first inserting protrusion 230 is an arc-shaped structural member, and the first inserting protrusion 230 is used to be in inserting engagement with the inserting groove 430 of the frame 400. In an alternative embodiment, the arc length of the first mating protrusion 230 is 10mm to 40mm and the radius is greater than 100mm.

In this embodiment, the pressing member 200 includes a pressing plate 220 and a first inserting protrusion 230, the pressing plate 220 is used for pressing the mask 500, and the first inserting protrusion 230 can be inserted into the inserting groove 430 of the frame 400 to improve the connection strength between the pressing bar and the frame 400, thereby improving the connection stability between the pressing bar and the frame 400. It should be noted that the first plugging protrusion 230 may be located above or below the pressing plate 220, which is not limited by the present utility model. In addition, the first plugging protrusion 230 in the present embodiment is an arc-shaped structure, and the length of the pressing member 200 is shorter, so that the arc length of the first plugging protrusion 230 is also shorter, and therefore the first plugging protrusion 230 can be adapted to the plugging grooves 430 with different sizes and arc shapes, and even to the plugging grooves 430 extending along a straight line. It can be seen that the first inserting protrusion 230 of the present embodiment can be adapted to the frame 400 with various shapes when it is an arc-shaped structure, so that the pressing bar is adapted to the lamps with various shapes.

In an alternative embodiment, the bead may be injection molded, and to facilitate demolding of the bead, it is common for at least a portion of the bead structure to have a draft angle, such as: the pressing plate 220 is provided with a demoulding slope, the demoulding direction is parallel to the width direction of the pressing plate 220, and one end of the pressing plate 220 connected with the pressing bar main body 100 extends to the other end of the pressing plate 220, in this case, the cross section area of the pressing plate 220 gradually decreases along the demoulding direction, and the required demoulding slope is also larger due to the larger thickness of the pressing plate 220, which can cause the plate surface of the pressing plate 220 to be too inclined, so that the contact length between the pressing plate 220 and the mask 500 can be reduced, and the pressing reliability of the pressing plate 200 to the mask 500 can be reduced.

In an alternative embodiment, the bottom surface of the pressing plate 220 is provided with a plurality of pressing ribs 210, the plurality of pressing ribs 210 are spaced along the extending direction of the pressing bar main body 100, and the pressing ribs 210 extend along the width direction of the pressing plate, the thickness of the pressing ribs 210 is smaller than that of the pressing plate 220, and the pressing ribs 210 are used for pressing the mask 500. In this embodiment, when the pressing member 200 presses the mask 500 of the lamp, the bottom surface of the pressing plate 220 faces the mask 500, a plurality of pressing ribs 210 are disposed at intervals on the bottom surface of the pressing plate 220, the pressing ribs 210 are used for pressing the mask 500, and the thickness of the pressing ribs 210 is smaller than that of the pressing plate, so that the demolding slope required by the pressing ribs 210 is smaller, which can reduce the slope of the pressing surface of the pressing ribs 210, so that a longer contact length exists between the pressing ribs 210 and the mask 500, and the reliability of pressing the mask 500 by the pressing member 200 is ensured.

To enhance the reliability of the compression bead against the mask 500, in an alternative embodiment, it further comprises: the pressing pieces 110 are located between the adjacent 2 pressing pieces 200 and are distributed at intervals along the extending direction of the pressing strip main body 100, the pressing pieces 110 are arranged on the pressing strip main body 100, and the pressing pieces 110 and the pressing pieces 200 protrude out of the pressing strip main body 100 on the same side of the pressing strip main body 100 in the width direction of the pressing strip main body 100. The width direction of the molding body 100 herein means the width direction of the molding body 100 when the molding body 100 is not yet deformed, and the width direction of the pressing member 200 is parallel to the width direction of the molding body 100.

The pressing piece 110 is used to press the mask 500 together with the portion of the pressing piece 200 protruding from the molding body 100 in the case where the connecting piece 300 is connected to the frame 400.

In addition, after the force application points of the pressing strips to the mask 500 are increased, the areas of the mask 500 adjacent to the force application points can be prevented from arching relative to the mounting convex part 410, so that gaps between the partial areas of the mask 500 and the mounting convex part 410 are eliminated, and mosquitoes and dust are prevented from entering the frame 400.

In an alternative embodiment, in the width direction of the molding body 100, one of the edges of the molding body 100 is bent to form the second insertion protrusion 120, and the second insertion protrusion 120 is used to be inserted into the insertion groove 430 of the frame 400. In this embodiment, the second insertion protrusion 120 formed by the molding body 100 can be inserted into the insertion groove 430 of the frame 400, so as to improve the connection strength between the molding and the frame 400. It should be noted that, when the present embodiment is combined with the technical solution that the pressing member 200 includes the pressing plate 220 and the first inserting protrusion 230, the bending direction of the pressing member 200 and the bending direction of the pressing member 100 may be the same, that is, the first inserting protrusion 230 and the second inserting protrusion 120 are located on the same side of the pressing member 100, and two end surfaces of the second inserting protrusion 120 are respectively attached to the corresponding first inserting protrusion 230, so that the first inserting protrusion 230 and the second inserting protrusion 120 may share the same inserting groove 430.

Further, among the more than 2 pressure-resisting members 200, at least 2 pressure-resisting members 200 are respectively located at two ends of the pressure-resisting member main body 100, so that the pressure-resisting member main body 100 and the pressure-resisting member 200 of the part can be formed into a split structure, and are connected by means of welding, bonding, clamping, threaded connection and the like, when the pressure-resisting member main body 100 and the pressure-resisting member 200 are formed into a split structure, the materials of the pressure-resisting member main body 100 and the pressure-resisting member 200 can be different, so that when the pressure-resisting member main body 100 is formed into a deformable structural member, the pressure-resisting member 200 is not easy to deform, and the reliability of the pressure-resisting member 200 for pressing the mask 500 can be increased.

In an alternative embodiment, the connection member 300 includes an elastic member 310, a first end of the elastic member 310 is connected to the molding body 100 or the pressing member 200, a second end of the elastic member 310 is connected to the frame 400, and the elastic member 310 is elastically deformed to press the pressing member 200 against the mask 500 when the connection member 300 is connected to the frame 400. In this embodiment, the connecting piece 300 includes an elastic piece 310, a first end of the elastic piece 310 is connected to the molding body 100 or the pressing piece 200, after a second end of the elastic piece 310 is connected to the frame 400, the elastic piece 310 can be elastically deformed, so as to apply a force to the pressing piece 200 in a first direction, which is a direction extending from the pressing piece 200 to the mask 500, so as to press the mask 500 on the frame 400, that is, the elastic piece 310 can indirectly press the mask 500 by virtue of an elastic force generated by self deformation, so that the pressing force of the pressing piece 200 to the mask 500 can be increased, and the reliability of pressing the mask 500 by the pressing piece can be increased. In addition, since the elastic member 310 is elastically deformable, the position of the second end of the elastic member 310 is adjustable, so that the installation position of the connection member 300 can be adjusted, thereby improving the installation flexibility of the molding. The elastic deformation of the elastic member 310 may be compressive or tensile.

In an alternative embodiment, the connector 300 further includes a clamping plate 320, where one plate surface of the clamping plate 320 is connected to the second end of the elastic member 310, and a clamping portion 321 is disposed on the clamping plate 320, and the clamping portion 321 is used to be clamped with the clamping slot 420 of the frame 400. In this embodiment, the clamping plate 320 has two plate surfaces disposed opposite to each other in the thickness direction thereof, one of the plate surfaces of the clamping plate 320 is connected with the second end of the elastic member 310, the clamping plate 320 is provided with a clamping portion 321, when the connecting member 300 needs to be connected with the frame 400, only the clamping portion 321 needs to be clamped with the frame 400, and when the connecting member 300 needs to be detached from the frame 400, only the clamping portion 321 needs to be separated from the frame 400 to be matched with the frame 400, so that the assembly difficulty between the connecting member 300 and the frame 400 can be reduced. When the engaging portion 321 engages with the frame 400, the elastic member 310 is elastically deformed. In an alternative embodiment, the locking portion 321 may be a locking protrusion or a locking recess, and in the case that the locking portion 321 is a locking protrusion, the locking portion 321 may be locked with the locking groove 420 of the frame 400.

In an alternative embodiment, the elastic member 310 is a spring, and a portion of the spring protrudes in a thickness direction of the spring to form a bump. In the embodiment, the elastic member 310 is a spring plate, and compared with a spring, the spring plate has higher structural strength and is not easy to damage; in addition, a part of the elastic sheet is provided with a bulge part in a protruding mode along the thickness direction of the elastic sheet, and therefore the elastic sheet is easier to drive to deform. Of course, the elastic member 310 may be a spring, an elastic sleeve, or the like.

Further, the first end of the elastic member 310 is connected to the pressing member 200, the clamping portion 321 is disposed at the first end of the clamping plate 320, the elastic member 310 is disposed between the pressing member 200 and the clamping plate 320, and the bulge portion protrudes in a direction away from the clamping portion 321.

Further, the second side 104 of the pressing member 200 and the second end of the clip plate 320 each protrude from the ridge in the width direction of the molding body 100. In the present embodiment, the protrusion does not protrude from the second side 104 and the locking plate 320 in the width direction of the molding body 100, so that the protrusion is prevented from interfering with the components located in the central region of the mask 500.

In an alternative embodiment, the locking plate 320 has a third side 322 and a fourth side 323 opposite to each other, where the third side 322 is opposite to the protruding direction of the bump, and the third side 322 is a cambered surface protruding away from the fourth side 323, and the third side 322 of the locking plate 320 is used to contact the frame 400 when the locking portion 321 is locked with the frame 400. In an alternative embodiment, third side 322 has an arc length of 10mm to 40mm and a radius of greater than 100mm.

In the present embodiment, since the length of the locking plate 320 is shorter, the arc length of the third side surface 322 is also shorter, and therefore the third side surface 322 can be adapted to the arc-shaped frame 400 with different dimensions, and even to the frame 400 extending along a straight line. It can be seen that the third side 322 of the present embodiment is a frame 400 with an arc surface capable of adapting to various shapes, so that the pressing bar is adapted to various shapes of lamps.
