Description

Technical Field

[0001] The utility model relates to the field of installation and fastening, in particular to a flat plate connection mechanism. Background Art

[0002] The installation of two flat pieces is involved in many fields, such as escalators and construction. Taking the escalator field as an example, escalators are commonly installed in supermarkets, stations, airports, subway stations and other public places with concentrated passenger flow. It not only has a strong conveying capacity and can continuously transport passengers, but also has a beautiful appearance and is convenient to use. It has become one of the most commonly used means of transportation for people to travel. Guardrails, as the main components of escalators and moving walkways, can prevent passengers from tipping over or even falling to the sides, and are crucial to ensuring the operation of escalators and moving walkways.

[0003] The guardrail is composed of multiple sheet metal parts, so how to assemble it quickly and conveniently is particularly important. The existing guardrail cover and base plate are connected by screws and metal sliders. The cover is provided with a round hole matching the diameter of the screw, the base plate is provided with a long waist hole, and there is only one threaded hole on the metal slider. During assembly, the metal slider is first placed in the long waist hole of the base plate, and then the cover is installed. The screws pass through the round holes on the cover. The screws need to be aligned with the threaded holes on the metal slider to be locked. Therefore, the metal slider needs to be moved back and forth in the long waist hole of the base plate to find a suitable position to align with the screws, which is time-consuming and laborious.

[0004] In addition to the escalator field mentioned above, in the technical fields of automobiles, construction, etc., the installation of two flat pieces such as a cover plate and a bottom plate is also usually involved. However, there is currently no connection mechanism that facilitates the rapid assembly of two flat pieces. Utility Model Content

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] This embodiment provides a flat plate connection mechanism 100, which can be connected to two flat plate members (bottom plate and cover plate) through a connection member. The flat plate connection mechanism 100 is made of thermoplastic engineering plastics, such as polyamide (PA). This material has good strength and toughness, is easy to deform and press into during assembly, and ensures sufficient connection strength.

[0034] Figure 1 It is a structural schematic diagram of the flat plate connection mechanism in the embodiment of the utility model; Figure 2 It is a structural schematic diagram of the flat plate connection mechanism from another perspective in the embodiment of the utility model; Figure 3 It is a side view of the flat plate connection mechanism in the embodiment of the utility model.

[0035] like Figures 1 to 3As shown, the flat plate connection mechanism 100 includes a first locking portion 1, a second locking portion 2 and a base 3. The first locking portion 1 and the second locking portion 2 are symmetrically arranged at the left and right ends of the base 3. The first locking portion 1, the second locking portion 2 and the base 3 are integrally formed and form a U-shaped groove 4. The base 3 is provided with a plurality of base mounting holes 31 arranged in a straight line. In some embodiments, the inner wall of the base mounting hole 31 may be provided with a thread.

[0036] The first locking part 1 and the second locking part 2 both include a connecting plate 11, a vertical plate 12 and at least one undercut 13. One end of the vertical plate 12 is arranged on the base 3, and the other end is arranged on the connecting plate 11. The connecting plate 11 is nearly perpendicular to the vertical plate 12, and the connecting plate 11 is arranged to protrude from the vertical plate 12 in a direction away from the base mounting hole 31. In the figure, the inner sides of the vertical plates 12 on the left and right sides are provided with a plurality of arc grooves 14 arranged in a straight line. The arc grooves 14 on the left and right sides are arranged oppositely and form a plurality of connecting holes, and the plurality of connecting holes correspond to the plurality of base mounting holes 31 one by one and are arranged coaxially. The apertures of the connecting holes and the base mounting holes 31 are both smaller than the diameter of the connecting member 400. The connecting member 400 can be a screw. The screw can pass through the connecting hole and the base mounting hole 31 in sequence, and can be embedded in the inner wall material when the screw is driven in.

[0037] At least one process hole 15 is provided on the connecting plate 11, and the process hole 15 can be in other shapes such as a rectangle, a circle or a parallelogram. The process hole 15 corresponds to the undercut 13 one by one and is located directly above the undercut, which is convenient for demoulding. In other embodiments, one process hole 15 can correspond to multiple undercuts 13. The vertical plate 12 and the connecting plate 11 are provided with chamfers or rounded corners to facilitate the cooperation with the long waist-shaped mounting hole 201 of the bottom plate 200 and reduce stress concentration.

[0038] The undercut 13 is arranged on the outer side of the vertical plate 12, and is used to clamp the connecting plate 11 on the bottom plate. In this embodiment, the number of undercuts 13 on each vertical plate 12 is 2. The distance H between the undercut 13 and the connecting plate 11 matches the thickness of the bottom plate. The thickness of the undercut 13 is gradual, gradually widening from bottom to top, and can be in the shape of an inverted ladder, an inverted triangle, a cone, etc., so that the flat plate connection mechanism 100 is easy to insert into the long waist-shaped mounting hole 201 of the bottom plate 200. The distance between the outer side surfaces of the undercuts on the left and right sides is greater than the width of the mounting hole 201 of the bottom plate 200.

[0039] This embodiment also provides a tablet device 1000 .

[0040] Figure 4 It is a structural diagram of the flat plate connecting mechanism and two flat plate members (cover plate and bottom plate) assembled in the embodiment of the utility model; Figure 5 In the present utility model embodiment Figure 1 a cross-sectional view of the structure shown; Figure 6It is a simplified structural diagram of the bottom plate 200 in the embodiment of the utility model; Figure 7 It is a simplified structural diagram of the cover plate 300 in the embodiment of the present utility model.

[0041] Figure 4-7 The base plate 200 and cover plate 300 shown only show the shape of their mounting holes, and do not limit the length, width and other dimensions of the base plate and the cover plate, nor do they limit the ratio of these dimensions to the size of the mounting holes (the actual base plate and cover plate are very large in size, and only a small part including the mounting holes is taken here, and only a structural schematic diagram related to this application is provided).

[0042] like Figure 4 and Figure 5 As shown, the assembled tablet device 1000 at least includes a tablet connection mechanism 100, a bottom plate 200, a cover plate 300 and a connection member 400. Figure 6 As shown, the bottom plate 200 has a long waist-shaped mounting hole 201. Figure 7 As shown, the cover plate 300 has a circular mounting hole 301. The connecting member 400 passes through the circular mounting hole 301, the long waist-shaped mounting hole 201 and the base mounting hole 31 in sequence to connect the flat plate connecting mechanism 100 with the base plate 200 and the cover plate 300. The upper surface of the connecting plate 11 of the flat plate connecting mechanism 100 is in contact with the lower surface of the cover plate 300, the lower surface of the connecting plate 11 is in contact with the upper surface of the base plate 200, and the lower surface of the base plate 200 is in contact with the top surface of the undercut 13. The circular mounting hole 301 of the cover plate 300 is aligned with one of the several base mounting holes 31 of the flat plate connecting mechanism 100. In this embodiment, the connecting member 400 is a self-tapping screw.

[0043] In some embodiments, see Figure 8 and Fig. 9 , the connector 400 may also include an insert 401 and a fastener (not shown in the figure). The insert 401 is embedded in the base mounting hole 31, and may be embedded in the base mounting hole 31 by pressing, ultrasonic welding or injection molding. The insert 401 is provided with a threaded hole, and the insert 401 is threadedly connected with the fastener to lock the cover plate 300 and the base plate 200. The number of the inserts 401 may be multiple, corresponding to the number of the base mounting holes 31, and the multiple inserts 401 are respectively embedded in the base mounting holes 31. The insert 401 may also be an insert having multiple threaded holes arranged in a straight line, and the insert as a whole may be embedded in the base 3.

[0044] The assembly process of the flat plate connection mechanism 100, the bottom plate 200 and the cover plate 300 is as follows:

[0045] First, insert the base 3 of the flat plate connection mechanism 100 into the long waist hole 201 of the bottom plate 200, and then gradually press down. Due to the setting of the undercuts 13 of the vertical plates on the left and right sides (the total width of the outer side of the undercuts on both sides is greater than the width of the bottom plate mounting hole), the first locking part 1 and the second locking part 2 on the left and right sides of the U-shaped groove 4 gradually shrink toward the middle. When the undercuts 13 completely enter the lower part of the bottom plate 200, the first locking part 1 and the second locking part 2 on the left and right sides return to the initial state, and the bottom plate 200 is stuck between the undercuts 13 and the connecting plate 11. Then, install the cover plate 300 on the connecting plate 11, and finally lock it with screws 400. A plurality of linearly arranged base mounting holes 31 are provided on the flat plate connection mechanism 100, which are convenient for matching with the mounting holes 301 on the cover plate 300. The mounting holes 301 on the cover plate 300 are easily aligned with one of the several base mounting holes 31. The flat plate connection mechanism 100 in this embodiment solves the problem that the metal slider (equivalent to the nut) in the existing product needs to slide back and forth in the long waist hole 201 of the bottom plate 200, which makes it time-consuming and laborious to align the mounting holes 301 on the cover plate 300. The flat plate connection mechanism 100 in this embodiment is simple and convenient to assemble, which greatly improves the work efficiency.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, deformations and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
