Door and window transfer device for testing the three properties of doors and windows

Abstract

This utility model discloses a door and window transfer device for testing the three properties of doors and windows. The device includes a rectangular base with rollers, and railings with clamping mechanisms on both sides of the base for flexibly clamping the doors and windows from both sides during transfer. In the middle of the base, multiple synchronously lifting rollers driven by a linkage mechanism are located. During operation, the lifting rollers are raised by a crank handle, lifting the doors and windows off the base, allowing them to slide into the testing equipment with low friction due to the rolling of the lifting rollers, greatly reducing the labor intensity during positioning. This utility model, by integrating clamping, lifting, and roller conveyor functions, effectively solves the problems of low efficiency, poor safety, and difficulty in alignment associated with traditional manual handling and flatbed truck transfer.

Description

Technical Field

[0001] This utility model relates to the field of auxiliary technology for building door and window testing, specifically a door and window transfer device for testing the three properties of doors and windows. Background Technology

[0002] In the three-property testing of building doors and windows, the doors and windows to be tested need to be transferred from the storage area and precisely installed onto fixed testing equipment. Currently, this transfer process mostly relies on manual handling or the use of ordinary flatbed carts. Manual handling is not only labor-intensive and inefficient, but also poses a high safety risk for large doors and windows. Furthermore, the edges or glass of the doors and windows are easily damaged during handling, affecting the accuracy of the test results. While using ordinary flatbed carts is less labor-intensive, they lack effective securing measures, making the doors and windows prone to swaying and tipping over during transport. In addition, when aligning the doors and windows with the installation port of the testing equipment, ordinary flatbed carts cannot make fine adjustments to height and position, leading to alignment difficulties. This requires multiple people to repeatedly pick up and adjust the doors and windows. Even after adjustment, personnel need to push the doors and windows from the flatbed cart onto the testing equipment, a process that is labor-intensive due to friction. Therefore, there is an urgent need for a specialized device that can safely and efficiently transfer doors and windows and assist in precise positioning. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a door and window transfer device for testing the three properties of doors and windows. It can not only replace manual labor to achieve safe and stable transfer of doors and windows, effectively prevent shaking, tipping and product collision during transportation, but also has lifting and roller conveyor functions to solve the prominent problems of high friction, high labor intensity and difficulty in positioning of doors and windows when finally aligned at the testing station.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a door and window transfer device for testing the three properties of doors and windows, including a base, a roller at the bottom of the base, the base being a rectangular frame structure, railings on both sides of the base, and a clamping mechanism at the top of the railings; The base has multiple lifting rollers in the middle that can be raised and lowered synchronously.

[0005] In a preferred embodiment, the outer walls on both sides of the base are provided with support rod seats, the support rod seats are provided with vertical threaded holes, and a screw rod passes through the threaded holes; The lower end of the screw is provided with a pad.

[0006] In a preferred embodiment, the two ends of the roller shafts of the plurality of lifting rollers are respectively installed on the inner sides of two strips, and a first hinge seat is provided on the outer side of the strips; A guide rod is inserted under the base, and two sliding cylinders are provided on the guide rod. A second hinge seat is provided on the sliding cylinder. The first hinge seat and the second hinge seat are connected by a connecting rod, with both ends of the connecting rod hinged to the first hinge seat and the second hinge seat respectively.

[0007] In a preferred embodiment, there are two guide rods, one of which has two threads with opposite directions of rotation. Two sliding cylinders are located on the two threads and are threadedly engaged with the guide rod.

[0008] In a preferred embodiment, the two sliding cylinders on the same side are connected by a straight rod.

[0009] In a preferred embodiment, one end of a threaded guide rod extends to the outside of one side of the base, and a manual crank is provided on that end of the guide rod.

[0010] In a preferred embodiment, the clamping mechanism includes a fixed inner sleeve and a movable outer sleeve. The fixed inner sleeve is fixed to the horizontal part of the railing, and the movable outer sleeve is sleeved outside the fixed inner sleeve and can rotate axially relative to the fixed inner sleeve. A torsion spring is provided between the movable outer sleeve and the fixed inner sleeve.

[0011] In a preferred embodiment, a bracket is fixedly provided on the outside of the movable outer sleeve, and a flexible sleeve roller is provided on the bracket.

[0012] The door and window transfer device for testing the three properties of doors and windows provided by this utility model has the following beneficial effects by adopting the above structure: (1) By using the lifting roller mechanism, the door and window can be disengaged from the device base by operating the lifting roller when the transfer is in place. The rolling friction of the roller greatly reduces the resistance to push the door and window into the detection equipment, making the final positioning operation easy and quick. (2) The clamping mechanism on both sides of the railing can be used to flexibly clamp the doors and windows from both sides during the transfer process, effectively preventing them from shaking or tipping over. This ensures operational safety and avoids damage to the doors and windows due to collisions. Attached Figure Description

[0017] like Figure 1-3 In the present invention, a door and window transfer device for testing the three properties of doors and windows includes a base 1, a roller 2 at the bottom of the base 1, the base 1 having a rectangular frame structure, railings 15 on both sides of the base 1, and a clamping mechanism 16 at the top of the railings 15. The base 1 is provided with multiple lifting rollers 6 that can be raised and lowered synchronously in the middle.

[0018] In a preferred embodiment, the outer walls on both sides of the base 1 are provided with support rod seats 3, the support rod seats 3 are provided with vertical threaded holes, and screws 4 are inserted through the threaded holes; The lower end of the screw 4 is provided with a pad 5.

[0019] In a preferred embodiment, the two ends of the roller shafts of the plurality of lifting rollers 6 are respectively installed on the inner sides of two strip plates 7, and a first hinge seat 8 is provided on the outer side of the strip plates 7; A guide rod 12 is inserted below the base 1. Two sliding cylinders 9 are provided on the guide rod 12. A second hinge seat 10 is provided on the sliding cylinder 9. The first hinge seat 8 and the second hinge seat 10 are connected by a connecting rod 11. The two ends of the connecting rod 11 are respectively hinged to the first hinge seat 8 and the second hinge seat 10.

[0020] In a preferred embodiment, there are two guide rods 12, one of which has two threads 13 with opposite directions of rotation. The two sliding cylinders 9 are located on the two threads 13 and are threadedly engaged with the guide rod 12 through the threads 13.

[0021] In a preferred embodiment, the two sliding cylinders 9 on the same side are connected by a straight rod.

[0022] In a preferred embodiment, one end of a guide rod 12 with the thread 13 extends to the outside of one side of the base 1, and a manual crank handle 14 is provided on that end of the guide rod 12.

[0023] In a preferred embodiment, the clamping mechanism 16 includes a fixed inner sleeve 161 and a movable outer sleeve 162. The fixed inner sleeve 161 is fixed on the horizontal part of the railing 15, and the movable outer sleeve 162 is sleeved outside the fixed inner sleeve 161 and can rotate axially relative to the fixed inner sleeve 161. A torsion spring is provided between the movable outer sleeve 162 and the fixed inner sleeve 161.

[0024] In a preferred embodiment, a bracket 163 is fixedly provided on the outside of the movable outer sleeve 162, and a flexible sleeve roller 164 is provided on the bracket 163.

[0025] Based on the above embodiments, when performing door and window transfer operations: The operator first moves the device to the storage position of the door or window to be transferred via the bottom rollers 2. By cranking the hand crank 14, the guide rod 12 with the reverse thread 13 drives the sliding cylinders 9 on both sides to move towards each other, which in turn pushes the strip 7 and the multiple lifting rollers 6 installed on it to descend via the connecting rod 11, so that the top surface of the lifting rollers 6 is lower than the bottom plane of the door or window.

[0026] The doors and windows are vertically hoisted or lifted to the middle of the device base 1, so that their bottoms are placed directly on the frame of the base 1. At this time, the clamping mechanisms 16 on the side rails 15 can be rotated. Specifically, the operator moves the bracket 163, causing the movable outer sleeve 162 to rotate outward against the force of the torsion spring, making room for the doors and windows to be positioned. After positioning, the bracket 163 is released, and under the action of the torsion spring, the movable outer sleeve 162 returns to its original position, causing the flexible sleeve roller 164 on it to fit tightly against the side frames of the doors and windows, achieving flexible clamping and limiting, and preventing the doors and windows from shaking or tipping over during transportation.

[0027] After being transported to the vicinity of the testing equipment installation port, the screws 4 on both sides of the base 1 can be rotated to make the lower pad 5 contact the ground, thus firmly supporting the entire device and preventing it from moving during the alignment process.

[0028] Then, crank the hand crank 14 again, causing the guide rod 12 to drive the sliding cylinder 9 to move in the opposite direction. This, in turn, pushes the strip plate 7 upward via the connecting rod 11, thereby simultaneously lifting multiple lifting rollers 6. The lifting rollers 6 lift the door / window away from the frame of the base 1. At this point, the weight of the door / window is entirely borne by the lifting rollers 6, and they are no longer in contact with the base 1. The operator can then easily push the door / window, using the rolling motion of the lifting rollers 6 to slide it with low friction into the installation port of the testing equipment, completing a precise and labor-saving alignment and installation.
