Description

TECHNICAL FIELD

[0001] The present application relates to door and window fittings, and more particularly to a guide wheel assembly and a guide wheel device. BACKGROUND

[0002] Push-pull doors and windows have the advantages of simplicity, beauty, wide view and high light transmittance, but their sealing performance is poor due to their sliding structure, which limits the use of push-pull doors and windows to some extent. The emergence of side pressure doors and windows solves the shortcoming of poor sealing performance of push-pull doors and windows. The side pressure system of side pressure doors and windows makes the door / window leaf body translate laterally (in the thickness direction of the leaf body) to press the outer frame to form a seal, thus having the performance of side-hung doors and windows and the advantage of large light transmittance of push-pull doors and windows.

[0003] However, in the existing side pressure push-pull door and window system on the market, there is a gap between the upper guide wheel body and the door / window frame guide rail. When the leaf body is opened and a reciprocating force perpendicular to the leaf body is applied, the leaf body will swing due to the gap between the wheel body and the guide rail, generating noise and affecting the use effect of the door and window. CONTENT OF THE UTILITY MODEL

[0004] The technical problem to be solved by the present application is to provide a guide wheel assembly and a guide wheel device that can automatically compensate for the gap between the guide wheel and the guide rail, in view of the above-mentioned defects of the prior art.

[0005] To solve the technical problem, the present application provides a guide wheel assembly in a first aspect, comprising a support seat and a guide wheel rotatably mounted above the support seat. The support seat is provided with an anti-swing block, which is slidably mounted above the support seat in a laterally elastic manner, and has a tendency to always extend outwardly to the lateral side of the support seat beyond the guide wheel.

[0006] According to one embodiment of the guide wheel assembly of the first aspect of the present application, the support seat is provided with a mounting seat, and a laterally extending mounting groove is formed in the mounting seat. The anti-swing block is slidably mounted in the mounting groove, and a resilient member is abutted between the lateral inner end of the anti-swing block and the lateral inner end of the mounting groove. The elastic force of the resilient member causes the lateral outer end of the anti-swing block to extend outwardly to the lateral side of the support seat beyond the guide wheel.

[0007] According to one embodiment of the guide wheel assembly of the first aspect of the present application, the anti-swing block has an abutment head extending outwardly to the lateral side of the mounting seat. The lateral outer end of the abutment head forms an abutment surface, and an inclined action surface is formed above the abutment surface and inclined inwardly.

[0008] According to one embodiment of the guide wheel assembly of the first aspect of the present application, the front and rear sides of the anti-swing block perpendicular to the sliding direction are provided with limiting protrusions, the front and rear sides of the mounting groove are provided with limiting strips, and notches are formed in the limiting strips for the limiting protrusions to be inserted into; after the anti-swing block is inserted into the notches in the limiting strips by the limiting protrusions, the anti-swing block is slid laterally outward by the elastic member, so that the limiting protrusions are in abutment with the limiting strips from top to bottom.

[0009] According to one embodiment of the guide wheel assembly of the first aspect of the present application, the elastic member is a compression spring, and the lateral inner end of the anti-swing block is provided with a mounting hole for mounting one end of the compression spring.

[0010] According to one embodiment of the guide wheel assembly of the first aspect of the present application, the guide wheel includes two guide wheels arranged at the two ends of the support seat in the front-rear direction perpendicular to the lateral direction, and the anti-swing block is mounted on the support seat between the two guide wheels.

[0011] To solve the technical problems, the present application provides a guide wheel device in a second aspect, which includes a base and a guide wheel assembly laterally slidably mounted in the base, wherein the guide wheel assembly is the aforementioned guide wheel assembly.

[0012] According to one embodiment of the guide wheel device of the second aspect of the present application, a slide groove extending laterally and through the base is formed, and the two ends of the support seat of the guide wheel assembly are formed into slide blocks slidably mounted in the slide groove in cooperation with the slide groove.

[0013] The guide wheel assembly and the guide wheel device of the present application have the following beneficial effects: the guide wheel assembly according to the embodiments of the present application is provided with a laterally elastically loaded anti-swing block on the support seat of the guide wheel, which is elastically forced to protrude outward beyond the guide wheel to abut against the side wall of the guide rail after the guide wheel is mounted in the guide rail, thereby automatically compensating for the assembly gap between the guide wheel and the guide rail. When the guide wheel device using the guide wheel assembly is applied to a side pressure door and window system, the gap between the guide wheel and the guide rail can be eliminated, the door / window leaf can be prevented from swinging, the use effect of the door / window can be improved, and customer satisfaction can be increased.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application, and are not used to limit the present application. And, the examples in the present application and the features in the examples can be combined with each other without conflict.

[0021] Figure 1 and Figure 2 respectively show the overall structure and partial exploded structure schematic view of the guide wheel device 100 according to an embodiment of the present application. Referring to Figure 1 and Figure 2 , the guide wheel device 100 is mainly composed of a guide wheel assembly 10 and a base 20, and the guide wheel assembly 10 is laterally slidably installed in the base 20. When the guide wheel device 100 is applied to a side pressure door and window system, the base 20 is fixed on the door and window leaf body, and the guide wheel assembly 10 is installed on the outer frame guide rail 200 (see Figure 4 ) through the guide wheel 12. Operating the door and window handle can make the guide wheel assembly 10 and the base 20 relatively slide laterally through the force transmission of the hardware components of the door and window, so as to realize the lateral translation of the door and window leaf body. This specific implementation is already a prior art, and will not be described in detail in the present application.

[0022] Specifically referring to Figure 1As shown, the guide wheel assembly 10 further comprises a support base 11 and two guide wheels 12 rotatably mounted above the support base 11. The base 20 is provided with a slide groove 21 extending laterally through the base 20, and the support base 11 is provided with slide blocks 111 at both ends thereof in the front-rear direction perpendicular to the lateral direction, and the support base 11 is slidably mounted in the slide groove 21 through the slide blocks 111 at both ends thereof to realize lateral sliding relative to the base 20. In specific implementation, the slide groove 21 and the slide blocks 111 can be a T-shaped groove and a T-shaped slide block as in the illustrated embodiment, or other sliding fitting structures such as dovetail grooves and dovetail slide blocks.

[0023] Referring again to Figure 1 As shown, the support base 11 is provided with mounting posts 112 at both ends thereof at the upper portion of the support base 11, and the two guide wheels 12 are rotatably mounted on the mounting posts 112 by, for example, riveting. The support base 11 is further provided with a mounting base 13 between the two guide wheels 12, and a swing-preventing block 14 is slidably mounted in the mounting base 13 in an elastically loaded manner along the lateral direction of the support base 11. The swing-preventing block 14 has a tendency to always extend outward beyond the guide wheels 12 under the action of the elastic force.

[0024] Referring in particular to Figure 2 and Figure 3 As shown, the mounting base 13 is provided with a mounting groove 131 extending laterally therein, and the swing-preventing block 14 is slidably mounted in the mounting groove 131. The swing-preventing block 14 is provided with a mounting hole 144 at the lateral inner end thereof, and one end of an elastic member 15 (for example, a compression spring) is accommodated in the mounting hole 144, and the other end of the elastic member 15 abuts against the lateral inner end of the mounting groove 131, so as to apply an elastic force to the swing-preventing block 14 to make the lateral outer end of the swing-preventing block 14 extend outward beyond the guide wheels 12. Specifically, the swing-preventing block 14 is provided with an abutting head 141 extending outward beyond the mounting base 13 in the lateral direction, and the lateral outer end of the abutting head 141 is provided with an abutting surface 142 and an action inclined surface 143 inclined inward above the abutting surface 142. During the process of mounting the guide wheel assembly 10 into the guide rail 200 through the guide wheels 12, referring to Figure 4 As shown, when the two guide wheels 12 of the guide wheel assembly 10 are mounted from below the guide rail 200 along the first side wall 201 of the guide rail 200, the second side wall 202 on the other side of the guide rail 200 will first abut against the action inclined surface 143 on the abutting head 141 of the swing-preventing block 14 extending laterally, and a lateral action force is generated to push the swing-preventing block 14 inward, the swing-preventing block 14 slides inward along the mounting groove 131 to retract, the elastic member 15 is compressed, and the swing-preventing block 14 will not affect the mounting of the upper frame of the guide wheel 12. After the upper frame, the swing-preventing block 14 extends outward beyond the guide wheels 12 under the action of the elastic force of the elastic member 15 rebounding, and the abutting surface 142 on the abutting head 141 of the swing-preventing block 14 abuts against the second side wall 202 of the guide rail 200, so as to automatically compensate for the assembly gap between the guide wheels 12 and the guide rail 200, and avoid swinging.

[0025] Referring again to Figure 2 In combination Figure 3 As shown, the front and rear sides of the anti-swing block 14 perpendicular to the lateral sliding direction are provided with limiting protrusions 145, and the front and rear sides of the mounting groove 131 of the mounting base 13 are provided with limiting strips 132, and the limiting strips 132 are provided with notches 133 corresponding to the limiting protrusions 145 of the anti-swing block 14. When the anti-swing block 14 is mounted into the mounting groove 131 through the limiting protrusions 145 aligned with the notches 133, the elastic member 15 is compressed, and when the limiting protrusions 145 of the anti-swing block 14 are inserted into the notches 133 below the limiting strips 132, the elastic member 15 is rebounded by the elastic force, and the anti-swing block 14 is slid laterally outward along the mounting groove 131, so that the limiting protrusions 145 are misaligned with the notches 133 and abut against the limiting strips 132 upward and downward. In this way, the anti-swing block 14 can slide laterally along the mounting groove 131, and the anti-swing block 14 is prevented from being detached from the mounting groove 131, and the stability of the lateral sliding of the anti-swing block 14 is improved.

[0026] The guide wheel assembly 10 according to the above-mentioned embodiments of the present application is provided with the laterally elastically loaded slidable anti-swing block 14 on the support base 11 of the mounting guide wheel 12, and the guide wheel 12 is extended to abut against the guide rail. When the guide wheel device 100 using the guide wheel assembly 10 is used for the side-hinged door and window, the assembly gap between the guide wheel 12 and the guide rail 200 can be automatically compensated, and the swing of the door and window leaf body is avoided.

[0027] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application should be included in the protection scope of the present application.
