Description

Technical Field

[0001] This utility model relates to the field of polycarbonate sheet installation, and in particular to a lockable and easy-to-install PC polycarbonate sheet. Background Technology

[0002] Polycarbonate (PC) solid sheets are widely used in many fields such as building skylights, awnings, greenhouses, sound barriers, advertising signs, and equipment protective covers due to their excellent light transmittance, impact resistance, weather resistance, and lightweight properties. However, in practical applications, the efficiency of installation, ease of operation, sealing reliability, and potential damage to the sheets during installation have always been pain points that the industry urgently needs to address.

[0003] Existing installation methods include through-hole fixing with screws / bolts, which is the most traditional method. It requires drilling holes in the board and then using screws or bolts with washers, pressure blocks and other fasteners to fix the board to the support frame. The main drawback of this method is that it requires multiple steps such as positioning, drilling, installing fasteners and applying torque, which is time-consuming and labor-intensive, especially when installing over a large area, it is inefficient.

[0004] Secondly, metal or plastic strips are used to cover the edges of the panels, and the strips are fixed to the frame with screws. This method avoids directly drilling holes in the panels, but it still has drawbacks: additional accessories such as strips, sealing strips, connecting brackets, and a large number of fastening screws are required, and the installation requires multiple steps such as precisely aligning the panels, placing the sealing strips, installing the strips, and tightening the screws, which is not simple to operate. At the same time, the exposed strips and screw heads may affect the overall aesthetics. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a lockable and easy-to-install PC endurance board to solve the technical problems in the prior art.

[0006] To achieve the above objectives, this utility model provides a lockable and easy-to-install PC endurance board, comprising:

[0007] The plate has an upper reinforcing rib embedded integrally on its upper end face and a lower reinforcing rib embedded integrally on its lower end face.

[0008] The locking sleeve is horizontally and laterally slidably connected to the plate body through the upper and lower reinforcing ribs;

[0009] At least one positioning hole is provided on the upper reinforcing rib;

[0010] At least one through hole is provided on the locking sleeve, and a positioning pin slides through the through hole, one end of the positioning pin being able to be inserted into the positioning hole;

[0011] A retaining ring is fixed to the surface of the positioning pin;

[0012] A spring is fitted into the middle of the positioning pin, with its two ends abutting against the top wall of the through hole and the fixing ring, respectively.

[0013] Preferably, the lower end of the locking sleeve is provided with a T-shaped groove, and the upper reinforcing rib is configured as an outwardly convex T-shaped structure that slides in conjunction with the T-shaped groove.

[0014] Preferably, the upper end of the locking sleeve is provided with an L-shaped groove, and the lower reinforcing rib is configured as an inwardly concave L-shaped structure that slides in conjunction with the L-shaped groove.

[0015] Preferably, both the upper and lower reinforcing ribs are made of stainless steel profiles.

[0016] Preferably, there are multiple perforations, and the positions of the multiple perforations correspond one-to-one with the positions of the adjacent positioning holes.

[0017] Preferably, the end of the positioning pin has a guide slope, and the end of the upper reinforcing rib has a chamfer that matches the guide slope.

[0018] Preferably, a limiting block is fixedly installed at the bottom of the positioning hole, and the limiting block has an inclined surface on the side facing the positioning pin that matches the guide slope.

[0019] Preferably, the method further includes a fixing buckle, which is detachably installed at both ends of the plate and the locking sleeve, and the fixing buckle has a through groove that matches the cross-sectional shape of the lower reinforcing rib.

[0020] Preferably, the end of the locking sleeve is provided with a countersunk threaded groove, and the fixing buckle is threadedly connected to the countersunk threaded groove by a screw.

[0021] The beneficial effects of this utility model are as follows: The easy-to-install PC endurance board using the locking mechanism of this utility model, through the setting of components such as the board body, upper reinforcing rib, and positioning pin, can limit the upward lifting of the board body and enhance the stability of the board body installation by cooperating with the T-shaped groove on the locking sleeve and the upper reinforcing rib of the outward T-shaped structure, and with the L-shaped groove on the locking sleeve and the lower reinforcing rib of the inward L-shaped structure. In addition, after the locking sleeve is installed on the upper reinforcing rib on the upper part of the board body, the positioning pin is inserted into the positioning hole to form a firm mechanical interlock, preventing the board body from lifting and lateral disengagement, thus enhancing the stability of the installation. Moreover, through this sliding insertion installation method, the installation of PC endurance board is extremely quick. The key locking steps are automatically completed by the cooperation of positioning pin and spring, shortening the installation time and reducing the intensity of manual labor.

[0022] By using components such as lower reinforcing ribs, locking sleeves, and fixing clips, after the two plates are installed in the T-slots and L-slots of the locking sleeve, the PC endurance board in the L-slot is restricted by the lower reinforcing ribs at the bottom to move the top of the positioning pin out of the through hole, thus hiding the positioning pin inside the through hole. After being detachably installed at both ends of the assembled plates and locking sleeves by the fixing clips, the whole structure achieves an aesthetically pleasing effect and prevents accidental opening.

[0033] The first aspect of this utility model proposes a lockable and easy-to-install PC endurance board, such as... Figure 1-5 As shown, it includes:

[0034] Plate 1, with an upper reinforcing rib 101 embedded in the upper end face and a lower reinforcing rib 102 embedded in the lower end face;

[0035] The locking sleeve 2 is horizontally and laterally slidably connected to the plate body 1 through the upper reinforcing rib 101 and the lower reinforcing rib 102;

[0036] At least one positioning hole 4 is provided on the upper reinforcing rib 101;

[0037] At least one through hole 3 is provided on the latch sleeve 2, and a positioning pin 5 slides through the through hole 3, one end of the positioning pin 5 can be inserted into the positioning hole 4;

[0038] The retaining ring 6 is fixed to the surface of the positioning pin 5;

[0039] Spring 7 is fitted into the middle of positioning pin 5, and its two ends abut against the top wall of through hole 3 and fixing ring 6 respectively.

[0040] During the installation of PC endurance boards, first align the upper reinforcing rib 101 on the upper end face of the board 1 with and insert it into the T-slot 201 on the locking sleeve 2. Push the board 1 horizontally to the predetermined position. As the board 1 moves, the chamfer at the end of the upper reinforcing rib 101 on the upper end face of the board 1 presses against the inclined surface at the bottom of the positioning pin 5, pushing the positioning pin 5 to temporarily move upward against the force of the spring 7. The spring 7 is compressed and contracted. With the continued pushing of the board 1, when the upper reinforcing rib 101 is pushed into place, the positioning pin 5 automatically slides down under the action of the spring 7 and gets into the positioning hole 4 inside the upper reinforcing rib 101. The top moves into the perforation 3, forming a strong mechanical interlock to prevent the plate 1 from lifting up and coming out laterally, thus enhancing the stability of the installation. The lower reinforcing rib 102 on the lower end face of another plate 1 is slid horizontally into the L-shaped groove 202 on the locking sleeve 2, so that the lower reinforcing rib 102 at the bottom of the other plate 1 restricts the top of the positioning pin 5 from moving out of the perforation 3, thereby hiding the positioning pin 5 inside the perforation 3, which has the effect of being aesthetically pleasing and preventing accidental opening. The insertion method makes the installation of PC endurance board extremely quick, so as to facilitate the installation between multiple plates 1, further shortening the installation time and reducing the intensity of manual labor.

[0041] In this embodiment, a T-slot 201 is provided at the lower end of the locking sleeve 2, and the upper reinforcing rib 101 is configured as an outwardly protruding T-shaped structure that slides and engages with the T-slot 201. It should be noted that, since both the T-slot 201 and the upper reinforcing rib 101 are T-shaped, after the plate 1 is slidably inserted into the T-slot 201 at the bottom of the locking sleeve 2 via the upper reinforcing rib 101, the upward lifting of the plate 1 can be restricted, enhancing the stability of the plate 1 installation.

[0042] In this embodiment, the upper end of the locking sleeve 2 is provided with an L-shaped groove 202, and the lower reinforcing rib 102 is configured as a concave L-shaped structure that slides with the L-shaped groove 202. It should be added that, since both the L-shaped groove 202 and the lower reinforcing rib 102 are L-shaped, after the plate 1 is slidably inserted into the L-shaped groove 202 at the upper part of the locking sleeve 2 through the lower reinforcing rib 102 at the lower end, the upward lifting of the plate 1 can be further restricted.

[0043] In this embodiment: both the upper reinforcing rib 101 and the lower reinforcing rib 102 are stainless steel profiles. The upper reinforcing rib 101 and the lower reinforcing rib 102 are 304 / 316L austenitic stainless steel profiles, which can enhance the connection strength between the upper and lower ends of the plate 1.

[0044] In this embodiment, multiple through holes 3 are provided, and the positions of the multiple through holes 3 correspond one-to-one with the positions of adjacent positioning holes 4. It should be noted that by having multiple through holes 3 corresponding one-to-one with multiple positioning holes 4, multiple positioning pins 5 can lock the upper end of the plate 1, further improving the stability of the installation between the locking sleeve 2 and the plate 1.

[0045] In this embodiment, the end of the positioning pin 5 has a guide slope, and the end of the upper reinforcing rib 101 has a chamfer that matches the guide slope. When the plate 1 is pushed into the locking sleeve 2 through the upper reinforcing rib 101 at the top, the bottom slope of the positioning pin 5 and the chamfer of the upper reinforcing rib 101 reduce the friction between them, making it easier to push the positioning pin 5 upward and facilitate the pushing of the plate 1 into place.

[0046] In this embodiment, a limiting block 8 is fixedly installed at the bottom of the positioning hole 4. The limiting block 8 has an inclined surface on the side facing the positioning pin 5 that matches the guide slope. It should be noted that by setting the limiting block 8, the rotation of the positioning pin 5 is restricted when the PC endurance board vibrates frequently. When disassembling the board body 1 and the locking sleeve 2, by continuing to push the locking sleeve 2, the bottom slope of the positioning pin 5 can be pressed against the corresponding inclined surface of the limiting block 8, which facilitates the upward movement of the positioning pin 5 under pressure, thereby facilitating the subsequent disassembly of the positioning pin 5.

[0047] In this embodiment, a fixing buckle 9 is also included. The fixing buckle 9 is detachably installed at both ends of the plate 1 and the locking sleeve 2, and the fixing buckle 9 has a through groove that matches the cross-sectional shape of the lower reinforcing rib 102. During the installation of the plate 1, the locking sleeve 2 is first slid onto the upper reinforcing rib 101 installed on the upper end of the plate 1, and then the fixing buckle 9 is installed on both sides of the locking sleeve 2 with bolts to restrict the movement of the plate 1. At this time, when installing another plate 1, the lower reinforcing rib 102 at the lower end of the other plate 1 can be slidably inserted into the L-shaped groove 202 at the top of the locking sleeve 2 through the through groove on the fixing buckle 9, so as to realize the splicing of the two plates 1, so as to facilitate the installation between two adjacent plates 1.

[0048] In this embodiment, the end of the locking sleeve 2 is provided with a countersunk threaded groove, and the fixing buckle 9 is threadedly connected to the countersunk threaded groove by a screw. It should be noted that, since the threaded groove is a countersunk hole, the bolt is hidden after the fixing buckle 9 is installed in place, which enhances the aesthetics.
