Description

Technical Field

[0001] This utility model relates to the field of material placement rack technology, specifically a material limiting bracket. Background Technology

[0002] With societal and industrial progress and increased market demand, a large number of materials and workpieces are produced. These materials and workpieces are used in mechanical equipment. When stacked, they are scattered and inconvenient to handle. Therefore, a material limiting bracket is needed to store and limit the materials and workpieces, facilitating management and transportation, and bringing convenience to various processes in the factory.

[0003] However, the existing material limiting brackets have the following drawbacks: since some materials have different heights and require different placement spaces, the spacing between the trays of most material limiting brackets is fixed, which is not convenient to adjust according to the height of the materials. This makes it inconvenient to place some materials that are too tall on the material limiting brackets, reducing the practicality of the material limiting brackets. Therefore, the existing material limiting brackets need to be improved. Utility Model Content

[0004] The purpose of this utility model is to provide a material limiting bracket to solve the problem mentioned in the background art that the spacing height between the trays of the current material limiting brackets on the market is fixed, which is inconvenient to adjust according to the height of the material, resulting in some materials that are too tall being inconvenient to be placed on the material limiting bracket.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a material limiting bracket, comprising a base and a slide groove, a positioning wheel installed below the base, side frames fixed at both ends of the base, the slide groove being opened on the inner side of the side frames, a support plate provided on one side of the side frame, adjusting blocks connected to both ends of the support plate, the slide groove and the adjusting blocks being slidably connected, an adjusting mechanism installed at both ends of the support plate, an insert block connected to one side of the adjusting mechanism, slots evenly distributed on the inner wall of the side frame near the slide groove, the adjusting mechanism comprising a slider, a screw, a first gear, a second gear and a knob, and a screw installed in the grooves at both ends of the support plate via bearings.

[0006] Preferably, a first gear is fixedly sleeved on the outer side of the screw, a second gear is meshed on one side of the first gear, and a knob is connected to one side of the second gear via a drive shaft.

[0007] Preferably, the screw and the insert are threaded together, the two sides of the insert are connected to sliders, and the sliders are slidably connected to the inner wall groove of the support plate.

[0008] Preferably, both ends of the tray are movably connected to baffles via a first rotating shaft, and the baffles are equipped with limit mechanisms at both ends near the side frame.

[0009] Preferably, one side of the limiting mechanism is connected to the side frame, and a return spring is installed on the outer side of the limiting mechanism.

[0010] Preferably, the limiting mechanism includes a limiting rod, a limiting pin, and a second rotating shaft. The two ends of the baffle are slidably connected to the second rotating shaft, and the reset spring is sleeved on the outside of the second rotating shaft.

[0011] Preferably, a limiting pin is movably sleeved on the outer side of the second rotating shaft, and limiting rods are provided on both sides of the side frame near the limiting pin.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. Equipped with an adjustment mechanism, rotating the knob drives the second gear to rotate, which in turn drives the first gear to rotate. The first gear then drives the screw to rotate, causing the insert block to engage with the screw thread. The insert block then moves to one side on the screw, simultaneously causing the slider to slide in the groove on the inner wall of the tray. This causes one end of the insert block to disengage from the slot, and then the tray is pushed upwards, causing the tray to drive the adjustment blocks at both ends to slide upwards in the slide groove. After sliding to the appropriate height, the adjustment mechanism drives the insert block to insert into the slot for limiting. This can quickly limit the height of the tray, making it convenient to adjust the spacing between trays. Materials of different heights can be placed on the same material limiting tray, improving the practicality of the material limiting tray.

[0014] 2. A limit mechanism and baffle are provided. The baffle is rotated by rotating shaft number one, with one end of the baffle rotating around shaft number one until it is perpendicular to the support plate. Then, shaft number two is pulled to compress the return spring. Subsequently, the limit pin is rotated clockwise or counterclockwise so that the locking pin is engaged with the limit rod. Then, shaft number two is released, causing the return spring to rebound and drive shaft number two back to its original position. The return spring provides a pulling force, causing the limit pin to abut against both ends of the side frame, improving the stability of the limit pin. The baffle prevents material from slipping, improving the safety of the material limit support. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 This utility model provides a technical solution: a material limiting bracket, including a base 1 and a slide 12. A positioning wheel 2 is installed below the base 1, and side frames 7 are fixed at both ends of the base 1. The slide 12 is opened on the inner side of the side frame 7, and a support plate 3 is provided on one side of the side frame 7.

[0024] Please see Figures 1-5 The pallet 3 has adjusting blocks 9 connected to both ends, and the slide groove 12 is slidably connected to the adjusting blocks 9. Adjusting mechanisms 8 are installed at both ends of the pallet 3, and a plug 10 is connected to one side of each adjusting mechanism 8. The side frame 7 has equally spaced slots 11 on its inner wall near the slide groove 12. The adjusting mechanism 8 includes a slider 801, a screw 802, a first gear 803, a second gear 804, and a knob 805. The pallet 3 has internal slots at both ends through which shafts pass. A screw 802 is mounted on the support. A first gear 803 is fixedly sleeved on the outside of the screw 802. A second gear 804 meshes with one side of the first gear 803. A knob 805 is connected to one side of the second gear 804 via a drive shaft. The screw 802 and the insert 10 are threaded together. Slider blocks 801 are connected to both sides of the insert 10. The sliders 801 are slidably connected to the groove on the inner wall of the support plate 3. The cross-sectional shape of the insert 10 is "L".

[0025] In practice, due to the varying heights of some materials, different placement spaces are required. However, the spacing between the trays 3 of most material limiting brackets is fixed, making it inconvenient to adjust according to the material height. This results in some excessively tall materials being difficult to place on the material limiting brackets, reducing their practicality. When it is necessary to adjust the spacing between the trays 3, the knob 805 can be rotated, causing the knob 805 to drive the second gear 804 to rotate. The second gear 804 then drives the first gear 803 to rotate, which in turn drives the screw 802 to rotate, causing the insert block 10 and the screw 802 to rotate. The screw 10 engages with the screw 802, and then moves to one side on the screw 802, while simultaneously driving the slider 801 to slide in the groove on the inner wall of the tray 3. This causes one end of the screw 10 to disengage from the slot 11, and then the tray 3 is pushed upward, causing the tray 3 to drive the adjusting blocks 9 at both ends to slide upward in the slide groove 12. After sliding to a suitable height, the adjusting mechanism 8 drives the screw 10 to be inserted into the slot 11 for limiting. This can quickly limit the height of the tray 3, making it convenient to adjust the spacing height between the trays 3. Materials of different heights can be placed on the same material limiting tray, improving the practicality of the material limiting tray.

[0026] Please see Figures 1-3 and Figure 6 The two ends of the pallet 3 are movably connected to baffles 6 via a first rotating shaft 4. Limiting mechanisms 5 are installed on the two ends of the baffles 6 near the side frame 7. One side of the limiting mechanism 5 is connected to the side frame 7. A return spring 13 is installed on the outer side of the limiting mechanism 5. The limiting mechanism 5 includes a limiting rod 501, a limiting pin 502, and a second rotating shaft 503. The two ends of the baffle 6 are slidably connected to the second rotating shaft 503. The return spring 13 is sleeved on the outer side of the second rotating shaft 503. The limiting pin 502 is movably sleeved on the outer side of the second rotating shaft 503. The side frame 7 is provided with limiting rods 501 on both sides near the limiting pin 502. The limiting rods 501 are evenly distributed on the side frame 7. The limiting pin 502 has a slot on the side near the limiting rod 501.

[0027] In practice, some material limiting brackets use ordinary placement plates to place materials, lacking protective structures around them. During the movement of the material limiting bracket, materials can easily slip off the placement plates. After placing the materials on the tray 3, the baffle 6 can be rotated by the first rotating shaft 4. One end of the baffle 6 rotates around the first rotating shaft 4 until it is perpendicular to the tray 3. Then, the second rotating shaft 503 is pulled to compress the return spring 13. Subsequently, the limiting pin 502 is rotated clockwise or counterclockwise so that the locking slot of the limiting pin 502 is engaged with the limiting rod 501. Then, the second rotating shaft 503 is released, causing the return spring 13 to rebound and drive the second rotating shaft 503 back to its original position. The return spring 13 can provide a pulling force, causing the limiting pin 502 to abut against both ends of the side frame 7, improving the stability of the limiting pin 502. The baffle 6 can prevent materials from slipping, thus improving the safety of the material limiting bracket.

[0028] Working principle: When using this material limiting bracket, firstly, the baffle 6 is opened by the limiting mechanism 5, exposing the placement surface of the tray 3. Then, the spacing height between the trays 3 is adjusted according to the height of the material. The height between the trays 3 is quickly adjusted and limited by the adjusting mechanism 8. Then, the material is placed on the upper surface of the tray 3, and the baffle 6 blocks both ends of the tray 3 to prevent the material from slipping. Then, the side frame 7 can be pushed to make the positioning wheel 2 roll on the ground, moving the material limiting bracket to other working areas. The setting of the limiting mechanism 5 and the adjusting mechanism 8 improves the practicality and safety of the material limiting bracket.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
