Description

Technical Field

[0001] The present invention relates to the technical field of shower rooms, and more particularly to a connecting structure for a shower door frame. Background Art

[0002] During the construction of a shower room, the guide rail and the door frame edge need to be connected to each other to construct a complete door frame, and the door frame also needs to be fixedly connected to the wall. In the existing shower door frame structure, generally, the wall connector is first connected and fixed to the wall, and then the border shell for adjusting the installation gap between the door frame and the wall is connected and fixed to the guide rail through corresponding fasteners. Finally, the guide rail together with the border shell is connected to the wall connector. However, since the installation position needs to be continuously adjusted during the installation process to meet the installation requirements, there is usually an adjustment gap left in the connection holes between the border shell and the wall connector, and it is relatively common in the industry to use elongated screw holes for screw connection and fixation. It is not difficult to see that a large amount of redundant hole space will be left after the screws are installed in this elongated screw hole. This exposed screw hole not only affects the overall beauty of the door frame, but also makes the waterproof performance of the door frame poor due to the influence of the screw hole. Additionally, in the existing frame connection structure, usually the guide rail is connected to the border shell separately, and the border shell and the wall connector are connected through another connection structure, resulting in cumbersome installation steps and low installation efficiency. Summary of the Invention

[0003] The problem solved by the present invention is to provide a connecting structure for a shower door frame to overcome the defects in the prior art, making the installation between the guide rail, the border shell and the wall connector simpler, and enabling easy adjustment of the installation position, effectively improving the installation efficiency.

[0004] To solve the above problems, the present invention provides a connecting structure for a shower door frame, including a guide rail, a wall connector and a border shell. A connecting seat is installed at the end of the guide rail, and the other end of the connecting seat is connected to the border shell. An installation groove is provided on the wall connector, and a connecting block and an adjusting component are provided on the connecting seat. When the connecting block is fitted into the installation groove, the adjusting component is used to adjust the width dimension of the connecting block to achieve locking or loosening of the connecting block along its width direction with the installation groove.

[0005] The connection structure of the present invention has the following advantages compared with the prior art:

[0006] In the connection structure of the present invention, the installation and fixation between the guide rail, the frame shell and the wall connector can be achieved by only using a connection seat, a connection block and an adjustment component, which effectively simplifies the installation process and improves the installation efficiency. Specifically, when the adjustment component drives the connection block to increase in size in the width direction, the connection block expands outward in the width direction and locks on the two inner walls of the installation groove. At this time, the fixed connection of the three components of the guide rail, the wall connector and the frame shell can be achieved by using a connection seat structure, which is very convenient. On the contrary, when the adjustment component drives the connection block to reduce in width, the connection block is separated from the two inner walls of the installation groove to achieve the loosening of the connector and the installation groove, that is, to achieve the unlocking between the connection seat and the wall connector. At this time, the position between the frame shell and the wall connector can be adjusted, which is very convenient.

[0007] Furthermore, the connecting block includes two locking blocks arranged at intervals, and the adjusting assembly includes a supporting block and an adjusting block. When the adjusting block drives the supporting block to move between the two locking blocks, the two locking blocks are elastically deformed in the width direction and expanded to abut against and lock with the mounting groove. In the above structure, the two locking blocks are squeezed by the supporting block to expand outward in the width direction, so that the two locking blocks are tightly locked with the inner wall of the mounting groove. This driving method has a simple structure and is easy to drive, and the supporting block can provide an increased force to make the locking block and the inner wall of the mounting groove more firmly locked.

[0008] As an improvement, the connection seat is provided with a channel extending along its length direction, a guide rod is slidably inserted into the channel, and the support block is connected to one end of the guide rod near the locking block; an operation hole connected to the channel is provided on the side wall at the other end of the connection seat, and the adjustment block is mounted in the operation hole and cooperates with one end of the guide rod away from the locking block; a avoidance hole is provided on the side wall of the guide rail corresponding to the operation hole. In the above improved structure, the extension and retraction of the guide rod can be achieved by operating the adjustment block, thereby driving the support block to be tightened between the two locking blocks or to be separated from the two locking blocks. The structure is simple, and in this structure, the adjustment block can be operated through only one avoidance hole on the outer wall of the guide rail, which is convenient to operate.

[0009] In a further improvement, the end of the guide rod away from the support block is provided with a rack distributed along its axial direction, the adjustment block is a cylindrical knob, and the outer wall of the knob is provided with active teeth distributed circumferentially and meshing with the rack. In the above structure, the adjustment block is a cylindrical knob, and the outer wall of the knob is provided with active teeth, so that the adjustment block and the guide rod are adjusted in the form of meshing of gears and racks, that is, when adjusting, only the adjustment block needs to be rotated to achieve the extension and retraction of the guide rod, thereby driving the movement of the support block, and finally achieving the locking and loosening of the locking block and the installation groove.

[0010] Further improved, a positioning hole is provided at the center of the bottom of the operation hole, and a positioning convex column that cooperates with the positioning hole is convexly provided on the inner end surface of the knob. In the above improved structure, the arrangement of the positioning hole and the positioning convex column makes the installation position of the adjusting block in the operation hole more accurate, and has better stability when rotating the adjusting block, ensuring the smoothness of the cooperation between the driving gear and the rack.

[0011] Further improved, the connecting seat includes a first connecting portion and a second connecting portion. The first connecting portion is inserted and fitted in the installation cavity at the end of the guide rail; one side of the frame housing surrounds the outside of the wall connecting member, and the other side is provided with a fitting groove for the second connecting portion to be snap-fitted. The connecting block is arranged at one end of the second connecting portion away from the first connecting portion. In the above improved structure, the connecting seat is set into two parts, which are respectively installed with the guide rail and the frame housing, and the second connecting portion and the frame housing are connected by a snap-fit form without fasteners, making the installation of the three components more convenient and fast.

[0012] Further improved, a positioning convex plate that bends inward and extends vertically is provided on the inner wall of the fitting groove, and a positioning groove that cooperates with the positioning convex plate is provided on the outer wall of the second connecting portion. In the above improved structure, the arrangement of the positioning convex plate and the positioning groove makes the snap-fit of the connecting seat and the frame housing more convenient, and can also limit the position of the guide rail and the frame housing in the horizontal direction after connection.

[0013] Further improved, a partition is provided between the first connecting portion and the second connecting portion. When the two ends of the connecting seat are respectively connected to the guide rail and the frame housing, both sides of the partition are abutted against the outer walls of the guide rail and the frame housing. The partition provided in the above improved structure avoids direct contact between the guide rail and the frame housing during installation, thus playing a role in preventing scratching.

[0014] Further improved, a decorative cover for covering the outer wall of the avoidance hole is detachably provided on the guide rail, and a plug-in column is provided at one end of the decorative cover close to the frame housing, and a plug-in hole for the plug-in column to be inserted and fitted is provided on the frame housing. In the above improved structure, the added decorative cover not only covers the avoidance hole, improves the aesthetics, but also plays a waterproof role; on the other hand, the cooperation between the plug-in column and the plug-in hole enables the guide rail and the frame housing to be limited in the vertical direction after connection.

[0015] Further improved, two positioning blocks are provided on the connecting seat, and a channel for the plug-in column to pass through is provided between the two positioning blocks; positioning card slots are provided on the outer side walls of the two positioning blocks, and positioning buckles that cooperate with the positioning card slots are provided on the inner wall of the decorative cover. In the above structure, the decorative cover is detachably installed by a snap-fit form without using fasteners, and is convenient for disassembly and assembly. Description of the Drawings

Detailed implementation manners

[0025] To make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention will be given with reference to the accompanying drawings.

[0026] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by terms such as "bottom", "outer wall", "inner wall", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. Additionally, in the description of the present invention, the terms "first" and "second" are only for convenience of description and differentiation, and do not have specific meanings.

[0027] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the term "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0028] As Figure 1 、 2 shown, the present invention provides a connecting structure for a shower door frame, including a guide rail 1, a wall connector 2, and a frame housing 3. A connecting seat 4 is installed at the end of the guide rail 1, and the other end of the connecting seat 4 is connected to the frame housing 3. An installation groove 5 is provided on the wall connector 2, and a connecting block 6 and an adjustment component are provided on the connecting seat 4; when the connecting block 6 is fitted into the installation groove 5, the adjustment component is used to adjust the width dimension of the connecting block 6 to achieve locking or loosening of the connecting block 6 along its width direction with the installation groove 5. Specifically, when the adjustment component drives the dimension of the connecting block 6 in the width direction to increase, the connecting block 6 expands and locks on the two inner walls of the installation groove 5 in the width direction. At this time, the fixed connection of the three elements of the guide rail 1, the wall connector 2, and the frame housing 3 can be realized through a connecting seat 4 structure, which is very convenient; on the contrary, when the adjustment component drives the width dimension of the connecting block 6 to decrease, the connecting block 6 is separated from the two inner walls of the installation groove 5 to achieve the loosening of the connecting block 6 from the installation groove 5, that is, to unlock between the connecting seat 4 and the wall connector 2. At this time, the position between the frame housing 3 and the wall connector 2 can be adjusted.

[0029] As Figure 3As shown, the connection block 6 in this embodiment includes two locking blocks 6.1 arranged at intervals, and the adjustment assembly includes a support block 7 and an adjustment block 8. When the connection seat 4 is inserted and fitted in the installation groove 5, the support block 7 is driven to move between the two locking blocks 6.1 by operating the adjustment block 8, and the locking block 6.1 is driven to elastically deform and expand in the width direction until it abuts and locks against the installation groove 5. On the contrary, when it is necessary to drive the connection seat 4 and the installation groove 5 to loosen, just reversely operate the adjustment block 8 to drive the support block 7 to disengage from between the two locking blocks 6.1. When the support effect of the support block 7 is lost, the two locking blocks 6.1 are deformed and reset inwardly, so that the outer walls of the two locking blocks 6.1 are disengaged from the inside of the installation groove 5.

[0030] More specifically, in order to better achieve the locking effect between the locking block 6.1 and the mounting groove 5 in the above structure, tooth pressures 6.1.1 are provided on the outer walls of the two spaced locking blocks 6.1, and correspondingly, inverted teeth 5.1 matching the tooth pressures 6.1.1 are provided on the two inner side walls of the mounting groove 5. In this embodiment, for the convenience of processing, preferably, a mounting base is detachably mounted on the end of the wall connector 2, and the mounting groove 5 is provided on the mounting base. Of course, in other embodiments, the mounting groove 5 can also be directly processed on the body of the wall connector 2.

[0031] In the above structure, further, as Figure 2 , 5 As shown, a channel 9 extending along the length direction is provided on the connection seat 4, a guide rod 10 is slidably inserted in the channel 9, and the support block 7 is connected to one end of the guide rod 10 near the locking block 6.1; an operation hole 11 connected to the channel 9 is provided on the side wall at the other end of the connection seat 4, and the adjustment block 8 is mounted in the operation hole 11 and cooperates with one end of the guide rod 10 away from the locking block 6.1; and a avoidance hole 1.1 is provided on the side wall of the guide rail 1 corresponding to the operation hole 11. In this structure, the guide rod 10 is a strip of metal plate, and the support block 7 is a plastic injection molded part. Specifically, the support block 7 is connected to one end of the guide rod 10 by secondary injection molding, and a corresponding through hole is also provided at the end of the guide rod 10. During the secondary injection molding, the rubber material can enter the through hole, thereby ensuring the connection strength between the secondary injection molded support block 7 and the guide rod 10. Of course, in other embodiments, it is also possible to directly use metal materials to form the support block 7 and the guide rod 10 as one piece.

[0032] In this structure, the axial movement of the guide rod 10 can be achieved by directly operating the adjustment block 8 through the avoidance hole 1.1, thereby causing the support block 7 to be stuck between the two locking blocks 6.1 or to be disengaged from the two locking blocks 6.1. In this structure, the adjustment block 8 cooperates with the guide rod 10, specifically, the end of the guide rod 10 away from the support block 7 is provided with a rack 10.1 distributed along its axial direction, the adjustment block 8 is a cylindrical knob, and the outer wall of the knob is provided with active teeth 8.1 distributed circumferentially and meshing with the rack 10.1. By rotating the adjustment block 8 forward and reversely, the axial telescopic movement of the guide rod 10 can be achieved under the meshing action of the active teeth 8.1 and the rack 10.1. More specifically, for the convenience of operation, a fitting portion for cooperating with an operating tool is provided on the outer end face of the adjustment block 8, such as a slot, a cross slot or other structures.

[0033] In the above structure, in order to make the active tooth 8.1 more accurately match with the rack 10.1 when the adjustment block 8 is installed in the operation hole 11, a positioning hole 11.1 is provided at the bottom center of the operation hole 11, and a positioning boss 8.2 matching with the positioning hole 11.1 is provided on the inner end surface of the knob. Figure 3 , 6 shown.

[0034] In addition, in order to facilitate the connection between the connecting seat 4 and the guide rail 1 and the frame shell 3, the connecting seat 4 includes a first connecting portion 4.1 and a second connecting portion 4.2, wherein the first connecting portion 4.1 is inserted into the installation cavity at the end of the guide rail 1; one side of the frame shell 3 is arranged outside the wall connector 2, and the other side is provided with a fitting groove 3.1 for fitting the second connecting portion 4.2, and the connecting block 6 is arranged at an end of the second connecting portion 4.2 away from the first connecting portion 4.1. In this structure, after the connecting seat 4 and the guide rail 1 and the frame shell 3 are installed, the end face of the guide rail 1 is in contact with the side wall of the frame shell 3. In actual use, the guide rail 1 and the frame shell 3 are generally aluminum profiles. In order to prevent the connecting end faces of the guide rail 1 and the frame shell 3 from being scratched, the structure of the connecting seat 4 is optimized in this embodiment. Specifically, Figure 3 As shown, a partition plate 4.3 is provided between the first connection portion 4.1 and the second connection portion 4.2. When the two ends of the connection seat 4 are respectively connected to the guide rail 1 and the frame shell 3, the two sides of the partition plate 4.3 are respectively against the outer wall of the guide rail 1 and the frame shell 3. This structure avoids direct contact between the guide rail 1 and the frame shell 3, thereby playing a role in preventing scratches. In the above structure, when the upper end of the frame shell 3 is connected to the guide rail 1, the fitting groove 3.1 is opened at the upper end of the frame shell 1, and when the lower end of the frame shell 3 is connected to the guide rail 1, the fitting groove 3.1 is opened at the lower end of the frame shell 1. In this embodiment, only the connection structure between the upper end of the frame shell 3 and the right end of the guide rail 1 is specifically described.

[0035] like Figure 2As shown in the figure, in order to further improve the installation speed and simplify the installation process, in this embodiment, the first connecting portion 4.1 is inserted and fitted with an installation cavity preset at the end of the guide rail 1, and a corresponding fastener 14 is provided on the upper end surface of the first connecting portion 4.12. The connection strength between the connecting seat 4 and the guide rail 1 is further enhanced by the fastener 14, and the fastener 14 is arranged at the top of the shower room frame, without affecting the aesthetics of the overall structure.

[0036] On the other hand, in this structure, a positioning convex plate 3.2 that bends inward and extends vertically is provided on the inner wall of the fitting groove 3.1, and a positioning groove 4.2.1 that cooperates with the positioning convex plate 3.2 is provided on the outer wall of the second connecting portion 4.2, thereby realizing a detachable insertion structure between the connecting seat 4 and the frame housing 3. Specifically, during installation, first insert the connecting seat 4 into the guide rail 1, then insert the guide rail 1 and the connecting seat 4 together into the fitting groove 3.1 on the frame housing 3 vertically, and finally, by operating the adjusting block 8, drive the two locking blocks 6.1 on the connecting seat 4 into the installation groove 5 of the wall connector 2 pre-installed on the wall. This is very convenient. During the whole process, no fasteners are required between the connecting seat 4 and the frame housing 3, effectively simplifying the installation process and improving the installation efficiency. Moreover, the vertical insertion structure adopted in this structure can also limit the horizontal direction of the connection structure between the guide rail 1 and the frame housing 3, preventing horizontal deviation.

[0037] In addition, in the above structure, since an avoidance hole 1.1 for a professional tool to pass through to operate the adjusting block 8 is provided on the side wall of the guide rail 1, from the perspective of the overall shower room frame, the aesthetics is affected to a certain extent, and shower water is likely to enter the operation hole, affecting the service life of the adjusting component. Therefore, in this embodiment, a decorative cover 12 for covering the avoidance hole 1.1 is detachably provided on the guide rail 1, and a plug-in post 12.1 is provided at one end of the decorative cover 12 close to the frame housing 3, and a plug-in hole 3.3 for the plug-in post 12.1 to be inserted and fitted is provided on the frame housing 3. After such a setting, the decorative cover 12 realizes the functions of waterproofing and improving aesthetics, and can also limit the vertical direction of the connection structure between the guide rail 1 and the frame housing 3, as Figure 2 、 7 shown. Further, in the above structure, in order to facilitate the disassembly and assembly of the decorative cover 12, an arc-shaped inner groove 12.2 is provided on the outer surface of the decorative cover 12 on the side far from the plug-in post 12.1, so that a better force application point can be provided when manually disassembling and assembling the decorative cover 12.

[0038] As Figure 3As shown, two positioning blocks 13 are provided on the connecting seat 4. Specifically, the two positioning blocks 13 are arranged on the outer end surface of the first connecting portion 4.1 near the partition plate 4.3, and a channel for the insertion column 12.1 to pass through is provided between the two positioning blocks 13; furthermore, a notch communicating with the channel is also formed on the partition plate 4.3 between the first connecting portion 4.1 and the second connecting portion 4.2; in addition, positioning card slots 13.1 are provided on the outer side walls of the two positioning blocks 13, and positioning buckles 12.2 matching with the positioning card slots 13.1 are provided on the inner wall of the decorative cover 12, so that the disassembly and assembly of the decorative cover 12 are more convenient and no fasteners are required.

[0039] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will all fall within the protection scope of the present invention.
