Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to a door and window positioning wheel device. Background Technology

[0002] As a core functional component for ensuring the smooth movement of door and window sashes, the positioning wheel device's structural design and installation method directly affect construction efficiency and reliability. Existing positioning wheel devices generally employ a four-component linkage structure consisting of a fixed base, a sliding base, a steering transmission mechanism, and a sliding rod. In practice, installers must first slide the sliding rod separately into a pre-fabricated groove on the lower side wall of the door / window frame's wheel groove. Then, the sliding base assembly of the positioning wheel device is embedded into the wheel groove. Subsequently, the mechanical coupling between the steering transmission mechanism and the sliding rod, and the rigid connection between the fixed base and the door / window frame, are established sequentially through threaded connections.

[0003] However, the existing positioning wheel device adopts a split assembly method, which is not only cumbersome to operate, but also presents certain operational difficulties in connecting the slide rod and the steering transmission mechanism due to the limited space of the wheel groove after the positioning wheel device is embedded in the wheel groove. Utility Model Content

[0004] In view of this, the present invention provides a door and window positioning wheel device to solve the problems of the existing positioning wheel device, which adopts a split assembly method, which is not only cumbersome to operate, but also has certain operational difficulties in connecting the slide rod and the steering transmission mechanism due to the limited space of the wheel groove after the positioning wheel device is embedded in the wheel groove.

[0005] To achieve one, some, or all of the above objectives, or other objectives, this utility model proposes a door and window positioning wheel device, including a base, a slide block, a cam transmission assembly, and a slide rod. A pulley is provided on the lower side wall of the base. The slide block is slidably connected to the upper side wall of the base. A positioning structure is provided on the upper side wall of the slide block. The slide rod is laid along the length of the base on the upper side wall of the slide block and is slidably connected to the slide block through the positioning structure. The positioning structure restricts the slide rod to slide only along the length of the base. The cam transmission assembly is disposed on the upper side wall of the slide block. The slide rod is drivenly connected to the cam transmission assembly. Sliding the slide rod can drive the slide block to slide along the width of the base via the cam transmission assembly.

[0006] Preferably, the positioning structure is a positioning element, and at least two positioning elements are provided and distributed along the length direction of the slide. The positioning element is nail-shaped and fixedly mounted on the upper side wall of the slide with its tip facing down. The slide rod has a number of positioning holes that penetrate its top and bottom side walls along its length direction. The positioning holes correspond one-to-one with the positioning elements and are arranged along the length direction of the slide rod. The positioning element is slidably connected in the corresponding positioning hole, and its head abuts against the upper side wall of the slide rod.

[0007] Preferably, there are two positioning members, which are symmetrically arranged at the front and rear ends of the slide.

[0008] Preferably, the tip of the positioning member is screwed to the upper side wall of the slide by a thread.

[0009] Preferably, a first sliding groove is formed on the upper side wall of the slide block along its length direction, penetrating its left and right end walls, the positioning member is fixedly disposed on the bottom wall of the first sliding groove, and the sliding rod is slidably connected in the first sliding groove.

[0010] Preferably, the upper side wall of the slide block is provided with a protrusion, and the first slide groove is formed on the protrusion.

[0011] Preferably, the cam transmission assembly includes a drive block and a drive shaft. A second slide groove is formed on the upper side wall of the slide along the length direction. The drive block is slidably connected in the second slide groove. A drive port is formed on the drive block, penetrating its top and bottom side walls. An avoidance opening is formed on the bottom wall of the second slide groove. The drive shaft is fixed on the upper side wall of the base. The top end of the drive shaft passes through the avoidance opening and is slidably connected in the drive port. The lower side wall of the slide rod is fixed to the upper side wall of the drive block. Sliding the drive block can drive the drive shaft to slide from one end of the drive port to the other end. The reaction force of the drive shaft on the inner wall of the drive port drives the slide to slide along the width direction of the base.

[0012] Preferably, the slide bar and the drive block are connected by rivets.

[0013] Preferably, the top end of the drive shaft is slidably connected to the inner wall of the drive port via a bearing.

[0014] Implementing the embodiments of this utility model will have the following beneficial effects:

[0015] After adopting the above-mentioned door and window positioning wheel device, during use, the sliding rod is first slidably connected to the upper side wall of the slide block through the positioning structure. At the same time, the sliding rod and the cam transmission assembly are driven and connected. The sliding rod and the cam transmission assembly can be connected by adhesive, screws, or snap-fit. Then, the assembled door and window positioning wheel device is directly inserted into the wheel groove on the upper side wall of the door and window frame from top to bottom, so that the sliding rod extends into the groove at the bottom of the wheel groove. Finally, the upper side wall of the door and window frame and the slide block are fixedly connected by screws to complete the installation. This optimizes the installation logic of the door and window positioning wheel device, changing the traditional sliding connection of the sliding rod to the door and window frame to a direct sliding connection with the slide block. This avoids the connection between the sliding rod and the cam transmission assembly being limited by the narrow space of the wheel groove, and reduces the installation difficulty of the door and window positioning wheel device.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings of this invention are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0022] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0024] like Figure 1-2As shown, a door and window positioning wheel device includes a base 1, a slide 2, a cam transmission assembly 3, and a slide rod 4. A pulley 11 is provided on the lower side wall of the base 1. The slide 2 is slidably connected to the upper side wall of the base 1, and a positioning structure is provided on the upper side wall of the slide 2. The slide rod 4 is laid on the upper side wall of the slide 2 along the length direction of the base 1 and is slidably connected to the slide 2 through the positioning structure. The positioning structure restricts the slide rod 4 to slide only along the length direction of the base 1. The cam transmission assembly 3 is disposed on the upper side wall of the slide 2, and the slide rod 4 is drivenly connected to the cam transmission assembly 3. Sliding the slide rod 4 can drive the slide 2 to slide along the width direction of the base 1 via the cam transmission assembly 3. In use, the slide rod 4 is first slidably connected to the upper side wall of the base 1 through the positioning structure. On the upper side wall of the slide block 2, the sliding rod 4 and the cam transmission assembly 3 are simultaneously driven and connected. The sliding rod 4 and the cam transmission assembly 3 can be connected by adhesive, screws, or snap-fit. Then, the assembled door and window positioning wheel device is simply inserted directly into the wheel groove on the upper side wall of the door and window frame from top to bottom, so that the sliding rod 4 extends into the groove at the bottom of the wheel groove. Finally, the upper side wall of the door and window frame and the slide block 2 are fixedly connected by screws to complete the installation. This optimizes the installation logic of the door and window positioning wheel device, changing the sliding rod 4 from the traditional sliding connection with the door and window frame to a direct sliding connection with the slide block 2. This avoids the connection between the sliding rod 4 and the cam transmission assembly 3 being restricted by the narrow space of the wheel groove, and reduces the installation difficulty of the door and window positioning wheel device.

[0025] It is understood that the positioning structure can be any or a combination of slots, holes, etc., that can restrict the slide rod 4 to the upper side wall of the slide block 2, and make the slide rod 4 only slide along the length direction of the slide block 2; the cam transmission component 3 refers to any transmission component that achieves reversing transmission through inclined plane sliding and extrusion. The cam transmission component 3 can be purchased through market channels and will not be described in this embodiment; the slide block 2 itself is fixedly connected to the door and window frame, and the two have the same motion state. Therefore, the slide rod 4 is slidably connected to the slide block 2, and its transmission properties on the door and window are not changed. When in use, the user can drive the slide rod 4 to slide through the door handle, and use the cam transmission component 3 to drive the slide block 2 to slide along the width direction of the base 1, thereby driving the door and window on the door and window positioning wheel device to move horizontally and close tightly.

[0026] Furthermore, the positioning structure is a positioning element 5. There are at least two positioning elements 5, which are distributed along the length direction of the slide block 2. The positioning element 5 is nail-shaped and fixedly installed on the upper side wall of the slide block 2 with the tip facing down. The slide rod 4 has a number of positioning holes 41 that penetrate its top and bottom side walls along its length direction. The positioning holes 41 correspond one-to-one with the positioning elements 5 and are arranged along the length direction of the slide rod 4. The positioning element 5 is slidably connected in the corresponding positioning hole 41, and its head abuts against the upper side wall of the slide rod 4 so that the slide rod 4 can only slide along its length direction by limiting the positioning element 5. At the same time, the head of the positioning element 5 is used to restrict the slide rod 4 from disengaging from the positioning element 5.

[0027] Furthermore, there are two positioning elements 5, which are symmetrically arranged at the front and rear ends of the slide block 2.

[0028] Furthermore, the positioning element 5 is a nail with external threads only at its tip. Its tip is screwed to the upper side wall of the slide block 2 through the threads, and the unthreaded part of its body is slidably connected to the inner wall of the positioning port 41.

[0029] Furthermore, a first groove 22 is provided on the upper side wall of the slide block 2 along its length direction, which passes through its left end wall and right end wall. The positioning member 5 is fixedly installed on the bottom wall of the first groove 22. The slide rod 4 is slidably connected in the first groove 22 so as to support the slide rod 4 through the inner wall of the first groove 22, so that the slide rod 4 slides more smoothly.

[0030] Furthermore, a protrusion 21 is provided on the upper side wall of the slide block 2, and a first sliding groove 22 is opened on the protrusion 21. The width of the protrusion 21 is smaller than the width of the sliding groove on the upper side wall of the door and window frame. Therefore, when the door and window positioning wheel device is inserted into the wheel groove on the upper side wall of the door and window frame from top to bottom, the protrusion 21 will extend into the sliding groove together with the slide rod 4.

[0031] Furthermore, the cam transmission assembly 3 includes a drive block 31 and a drive shaft 32. A second slide groove 23 is provided on the upper side wall of the slide block 2 along the length direction. The drive block 31 is slidably connected in the second slide groove 23. A drive port 311 is provided on the drive block 31, penetrating its top and bottom side walls. An avoidance port 24 is provided on the bottom wall of the second slide groove 23. The drive shaft 32 is fixed on the upper side wall of the base 1. The top end of the drive shaft 32 passes through the avoidance port 24 and is slidably connected in the drive port 311. The lower side wall of the slide rod 4 is fixed to the upper side wall of the drive block 31. The sliding slide rod 4 can drive the drive block 31 to slide in the second slide groove 23, forcing the drive shaft 32 to slide relative to one end of the drive port 311 to the other end. The reaction force of the drive shaft 32 on the inner wall of the drive port 311 drives the slide block 2 to slide along the width direction of the base 1, thereby driving the door and window to close. The drive block 31 can be purchased through market channels and will not be described in this embodiment.

[0032] Furthermore, the slide bar 4 is connected to the drive block 31 by rivets 6.

[0033] Furthermore, the top end of the drive shaft 32 is slidably connected to the inner wall of the drive port 311 via the bearing 7 to reduce the sliding friction between the two and make the drive shaft 32 slide more smoothly in the drive port 311.

[0034] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model.
