Description

Technical Field

[0001] The utility model relates to a transfer rack, in particular to an optical glass substrate transfer rack, and belongs to the technical field of transfer racks. Background Art

[0002] Optical glass substrate is a kind of amorphous optical medium material that can transmit light. Light passing through it can change the propagation direction, phase and intensity, etc. It is often used in optical instruments or mechanical systems. Optical glass substrates are usually transported through special transfer racks. During the transportation process, in order to prevent the optical glass substrate from tipping forward and overturning, the optical glass substrate is generally placed tilted in the direction of the support rack with its back against the support rack connected to the handle, or the transfer rack is slightly tilted toward the rear of the support rack when dragging it, so as to avoid the optical glass substrate from tipping forward and causing damage, thereby realizing the transportation of the optical glass substrate.

[0003] However, some larger optical glass substrates are also very heavy, and the support frame can hardly bear the weight of the optical glass substrate. Or the transfer frame is tilted and pulled, and the transfer frame relies heavily on the rear universal wheels to contact the ground for support. When the weight is too high, the universal wheels will slide backwards, causing the transfer frame to drive the optical glass substrate to tilt backward and overturn, causing damage to the optical glass substrate. Therefore, the existing transfer frame has poor stability, and because the operator stands behind the optical glass substrate, the optical glass substrate will tilt backward and overturn and hit the operator, which can easily cause a safety accident.

After sliding to a suitable position, the position of the support rod 11 is fixed with the limiting structure 8. At this time, the universal wheel 9 at the bottom end of the mounting plate 12 contacts the ground, forming a support point in contact with the ground.

[0023] As a technical optimization solution of the present utility model, the overall structure of the insertion rod 802 is an inverted "U" structure, the end cross-section of one end of the insertion rod 802 that is slidably connected to the connecting block 801 is a "T"-shaped structure, and the connecting block 801 is an inverted "U"-shaped structure; the end cross-section of the connecting block 801 is a "T"-shaped structure, which prevents the insertion rod 802 from slipping off the connecting block 801 when the insertion rod 802 is pulled upward.

[0026] As a technical optimization scheme of the utility model, the cross-section of the bracket 1 is an "L"-shaped structure, and a pallet 6 is installed on the bracket 1. The pallet 6 is inclined, and the installation height of the pallet 6 on one side facing the support frame 4 is lower than the installation height on the other side, and a plurality of grooves 16 are equidistantly provided on the pallet 6; since the pallet 6 is inclined toward the support frame 4, when the optical glass substrate is loaded on the transfer rack, the bottom end of the optical glass substrate contacts the pallet 6 and is perpendicular to the pallet 6, so the inclination direction of the optical glass substrate is opposite to the inclination direction of the pallet 6, so that the optical glass substrate contacts the support frame 4 backward, which can effectively prevent the optical glass substrate from tipping forward and overturning to cause damage, thereby improving the stability of the transfer rack.

[0027] As a technical optimization solution of the utility model, a handle 13 is installed on one side of the support frame 4, and a rubber sleeve 14 is provided on the handle 13.

Four universal wheels 9 are installed on the bottom end of the bracket 1; the handle 13 is convenient for operation during transportation, the setting of the rubber sleeve 14 increases the friction between the handle 13 during operation, and the setting of the rubber strip 17 and the rubber pad 15 increases the friction between the support plate 6 and the support frame 4 and the optical glass substrate, thereby preventing the optical glass substrate from slipping off the transport rack.

[0028] When the utility model is in use, first pull the insertion rod 802 upward, the insertion rod 802 slides out of one of the limiting holes 804 and no longer engages with the limiting hole 804, and at the same time the insertion rod 802 drives the second spring 803 to contract, and then use the other hand to pull the mounting plate 12, the mounting plate 12 drives the support rod 11 to slide outward on the bracket 1, and when it slides to a suitable position, the insertion rod 802 is released, the second spring 803 is reset, and drives the insertion rod 802 to engage with one of the limiting holes 804, so that the position of the support rod 11 is fixed, and at this time the universal wheel 9 at the bottom end of the mounting plate 12 The support plate 6 is tilted toward the support frame 4, and the optical glass substrate is pressed against the support frame 4. When the optical glass substrate is loaded on the transfer rack, the optical glass substrate is pressed against the support frame 4 backward. When the support frame 4 is subjected to force, the mounting plate 12 at the end of the support rod 11 drives the universal wheel 9 to press against the ground, thereby decomposing the gravity borne by the support frame 4, effectively preventing the optical glass substrate from tipping over backward, improving the stability of the transfer rack, improving flexibility, improving operating efficiency, and reducing safety risks during operation. Since the support plate 6 is tilted toward the support frame 4, when the optical glass substrate is loaded on the transfer rack , the bottom end of the optical glass substrate contacts the support plate 6 and is perpendicular to the support plate 6, so the inclination direction of the optical glass substrate is opposite to the inclination direction of the support plate 6, so that the optical glass substrate contacts the support frame 4 backward, which can effectively prevent the optical glass substrate from tipping forward and tipping over, causing damage, and improve the stability of the transfer frame; when the transfer frame is no longer in use, pull the guide rod 702 upward to drive the block 701 to move upward, the block 701 is no longer engaged with the slot 705, and then push the handle 13 forward, the handle 13 drives the support frame 4 to rotate in the direction of the support plate 6 until the support frame 4 contacts the support plate 6, Then, pull the insertion rod 802 upward so that the insertion rod 802 no longer engages with one of the limiting holes 804, and push the mounting plate 12 toward the inside of the bracket 1. The mounting plate 12 drives the support rod 11 to slide toward the inside of the bracket 1. When only the last limiting hole 804 of the support rod 11 is left outside the bracket 1, release the insertion rod 802, and the second spring 803 resets, driving the insertion rod 802 to engage with the last limiting hole 804, thereby fixing the support rod 11 and preventing the support rod 11 from sliding out when the transfer rack is placed, thereby storing the transfer rack and reducing the space occupied by the transfer rack.
