Description

Technical Field

[0001] This application relates to the field of logistics transportation auxiliary equipment technology, specifically a fixed bracket for logistics distribution. Background Technology

[0002] In the logistics and distribution industry, delivery vehicles (such as vans and electric tricycles) need to be frequently loaded with goods of various specifications and sizes. Due to the high frequency of delivery and the common practice of mixed loading of goods, the goods are prone to displacement or tipping during transportation. Therefore, a fixed support structure is required to ensure that the goods are stably placed in the vehicle compartment.

[0003] The current mainstream design scheme for cargo fixing brackets is as follows: a vertical rod-shaped bracket is installed on the side of the stacked cargo, and at the same time, an additional horizontal rod-shaped bracket is installed on the side of the vertical bracket away from the cargo, corresponding to the middle position of the vertical bracket. The horizontal bracket provides lateral support to the middle of the vertical bracket, thereby improving the stress strength and deformation resistance of the middle of the vertical bracket, and thus enhancing the fixing effect on the cargo.

[0004] However, in practical applications, because both the vertical and horizontal supports are slender rod-like structures—their length is much greater than their cross-sectional dimensions (i.e., their slenderness ratio is extremely high)—these structures inherently have weak bending resistance and are prone to bending deformation under external forces. When goods inside the vehicle shake due to transport bumps and impact the vertical supports laterally, the middle of the vertical supports, even with the support of the horizontal supports, is subjected to the impact force and is still prone to significant bending deformation. This causes the vertical supports to fail to continuously and stably hold the goods in place, ultimately leading to the failure of the goods to be secured, making it difficult to meet the requirements for cargo stability during logistics and distribution.

[0005] Therefore, this application provides a fixable bracket for logistics distribution to solve the above problems. Utility Model Content

[0006] This application provides a fixable bracket for logistics distribution, aiming to solve the problems mentioned in the background art, such as the fact that the vertical and horizontal supports of the existing cargo fixing brackets are all slender rod-shaped structures with a very large slenderness ratio and weak bending resistance. When the cargo in the carriage is subjected to lateral impact due to the bumps and swaying during transportation, the vertical support is still prone to bending and deformation in the middle, even with the support of the horizontal support, which ultimately leads to the failure of cargo fixing and makes it difficult to meet the requirements of logistics distribution for cargo fixing stability.

[0007] To achieve the above objectives, this application provides the following technical solution: a fixed support for logistics distribution, comprising a first sleeve, a first extension rod that moves axially within the first sleeve, and a drive mechanism for driving the first extension rod to move up and down along the first sleeve. The lower end of the first sleeve and the upper end of the first extension rod are both fixedly connected to a first foot support plate. To improve resistance to the middle of the first sleeve, an inclined support assembly is provided on the first sleeve. The inclined support assembly includes a second extension rod hinged to the top of the first sleeve and a second sleeve fitted onto the bottom of the second extension rod. A second foot support plate is hinged to the bottom of the second sleeve. The second sleeve and the second extension rod are also connected via the drive mechanism. The drive mechanism includes a frame plate fitted onto the first or second extension rod and fixedly connected to the first or second sleeve, a rotating shaft rotatably inserted into the frame plate, a rack fixedly connected to the first or second extension rod, and a gear fixedly fitted onto the rotating shaft for meshing with the rack. A crank handle is fixedly connected to the right end of the rotating shaft. In use, the drive mechanism drives the second extension rod to move along the second sleeve, adjusts the overall length of the second extension rod and the second sleeve, and then adjusts the angle of the oblique support, so that the second foot support plate is stably attached to the vehicle body, and finally forms an oblique support for the middle part of the first sleeve and the first extension rod, enhancing the force-bearing capacity of this part.

[0008] Preferably, to improve the stability of the first and second support plates in contact with the vehicle body, anti-slip and wear-resistant pads are fixedly connected to the outer ends of both the first and second support plates. This enhances the stability of the first and second support plates in contact with the vehicle body, prevents the first and second support plates from sliding on the vehicle body surface, reduces wear between the first and second support plates and the vehicle body, and extends the service life of the support plates.

[0009] Preferably, the anti-slip and wear-resistant pad is a rubber pad. This further enhances the anti-slip effect and wear resistance of the first and second foot support plates in contact with the vehicle body, and the elasticity of the rubber material can adapt to the slight unevenness of the vehicle body surface, enhancing the fit between the foot support plates and the vehicle body, and further improving contact stability.

[0010] Preferably, to prevent the gears from reversing during use, the left end of the frame plate has a groove, within which a ratchet fixedly fitted onto the left end of the rotating shaft is located. A pawl is rotatably mounted within the groove to prevent the ratchet from rotating clockwise, and the pawl engages with the ratchet. A spring is fixed between the pawl and the inner wall of the groove. This prevents the gears from reversing during use, avoiding accidental movement of the first or second extension rod along the first or second sleeve due to gear reversal, ensuring the bracket maintains a stable support state and guaranteeing effective cargo securing.

[0011] Preferably, to facilitate disengagement of the pawl's movable end from the ratchet, one end of the pawl's shaft passes through the frame plate and is fixedly connected to a knob. This allows the operator to quickly disengage the pawl's movable end from the ratchet, facilitating adjustments to the position of the first or second extension rod (such as retracting the bracket or adjusting the support height), thus improving the ease of bracket operation.

[0012] Preferably, to increase the friction between the hand and the first sleeve during carrying the bracket, multiple anti-slip protrusions are fixedly connected to both the left and right ends of the first sleeve. This increases the friction between the hand and the first sleeve during carrying, preventing slippage and allowing the operator to hold and carry the bracket stably, thus reducing the risk of the bracket falling during transport.

[0013] This application uses a diagonal support assembly to provide diagonal support for the vertically installed first sleeve and first extension rod, effectively improving the support force in the middle of the bracket and preventing the first sleeve and first extension rod from bending in the middle due to impact during cargo transportation, thus further ensuring that the cargo remains stable.

[0014] This application uses a ratchet and pawl mechanism to prevent the gears from reversing during the use of the bracket, thus avoiding accidental movement of the first or second extension rod along the first or second sleeve due to gear reversal. This ensures that the bracket always maintains a stable support state and guarantees the effective fixation of the goods. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0018] Example 1 This embodiment provides a fixable bracket for logistics distribution, such as... Figure 1-6 As shown, the bracket includes a first sleeve 1, a first extension rod 2 that moves axially within the first sleeve 1, and a drive mechanism 3 for driving the first extension rod 2 to move up and down along the first sleeve 1. The lower end of the first sleeve 1 and the upper end of the first extension rod 2 are both fixedly connected to first support plates 4. To improve the resistance to the middle of the first sleeve 1, a diagonal support assembly 5 is provided on the first sleeve 1. The diagonal support assembly 5 includes a second extension rod 51 hinged to the top of the first sleeve 1 and a second sleeve 52 fitted at the bottom of the second extension rod 51. A second support plate 53 is hinged to the bottom of the cylinder 52. The second sleeve 52 and the second extension rod 51 are also connected via a drive mechanism 3. The drive mechanism 3 includes a frame plate 31 for mounting on the first extension rod 2 or the second extension rod 51 and fixedly connected to the first sleeve 1 or the second sleeve 52, a rotating shaft 32 rotatably inserted into the frame plate 31, a rack 33 fixedly connected to the first extension rod 2 or the second extension rod 51, and a gear 34 fixedly mounted on the rotating shaft 32 for meshing with the rack 33. A crank handle 35 is fixedly connected to the right end of the rotating shaft 32. The inclined support assembly 5 can provide inclined support for the vertically installed first sleeve 1 and the first extension rod 2, effectively improving the support force in the middle of the support, preventing the first sleeve 1 and the first extension rod 2 from bending in the middle due to impact during cargo transportation, and further ensuring that the cargo remains stable. In use, the drive mechanism 3 drives the second extension rod 51 to move along the second sleeve 52, adjusts the overall length of the second extension rod 51 and the second sleeve 52, and then adjusts the angle of the oblique support, so that the second foot support plate 53 is stably attached to the vehicle body, and finally forms an oblique support for the middle part of the first sleeve 1 and the first extension rod 2, enhancing the force-bearing capacity of this part.

[0019] To improve the stability of the first support plate 4 and the second support plate 53 in contact with the vehicle body, anti-slip and wear-resistant pads 6 are fixedly connected to the outer ends of both the first support plate 4 and the second support plate 53. This enhances the stability of the first support plate 4 and the second support plate 53 in contact with the vehicle body, prevents the first support plate 4 and the second support plate 53 from sliding on the vehicle body surface, and reduces wear between the first support plate 4 and the second support plate 53 and the vehicle body, thus extending the service life of the support plates. When the bracket is installed and fixed, the anti-slip and wear-resistant pads 6 are in direct contact with the vehicle body surface; their anti-slip properties increase the friction between the first support plate 4 and the second support plate 53 and the vehicle body, preventing the support plates from shifting on the vehicle body; their wear-resistant properties reduce wear when the support plates are in contact with the vehicle body, ensuring the structural integrity of the support plates.

[0020] The anti-slip and wear-resistant pad 6 is made of rubber. It further enhances the anti-slip effect and wear resistance of the first foot support plate 4 and the second foot support plate 53 in contact with the vehicle body. The elasticity of the rubber material can adapt to the slight bumps and depressions on the vehicle body surface, enhance the fit between the foot support plate and the vehicle body, and further improve the contact stability.

[0021] To prevent gear 34 from reversing during use, a groove is provided at the left end of the frame plate 31. A ratchet 36, fixedly mounted on the left end of the rotating shaft 32, is installed within the groove. A pawl 37, rotatably positioned within the groove to allow the ratchet 36 to rotate clockwise, engages with the ratchet 36. A spring 38 is fixed between the pawl 37 and the inner wall of the groove. This design prevents gear 34 from reversing during use, avoiding accidental movement of the first extension rod 2 or the second extension rod 51 along the first sleeve 1 or the second sleeve 52 due to gear 34 reversal, ensuring the support remains stable and guaranteeing effective cargo securing. Spring 38 applies elastic force to pawl 37, so that pawl 37 always presses against ratchet 36, restricting ratchet 36 from rotating clockwise; since ratchet 36 and gear 34 are both fixedly mounted on shaft 32, when ratchet 36 is restricted from rotating, shaft 32 cannot rotate clockwise, thereby preventing gear 34 from rotating clockwise in reverse, avoiding gear 34 from driving rack 33 (fixed on first extension rod 2 or second extension rod 51) to move, and ensuring the stability of extension rod position.

[0022] To facilitate disengagement of the movable end of the pawl 37 from the ratchet 36, a knob 39 is fixedly connected to one end of the pawl 37 via a shaft that passes through the frame plate 31. This allows the operator to quickly disengage the movable end of the pawl 37 from the ratchet 36, facilitating adjustments to the position of the first extension rod 2 or the second extension rod 51 (e.g., retracting the bracket or adjusting the support height), thus improving the ease of bracket operation. When adjusting the position of the first extension rod 2 or the second extension rod 51, the operator manually rotates the knob 39. The knob 39 causes the shaft of the pawl 37 to rotate on the frame plate 31, causing the movable end of the pawl 37 to rotate around the shaft and disengage from the ratchet 36, releasing the rotational restriction on the ratchet 36 and the rotating shaft 32. At this time, the operator can turn the crank handle 35 to rotate the rotating shaft 32 and the gear 34. Through the meshing of the gear 34 and the rack 33, the position of the first extension rod 2 or the second extension rod 51 can be adjusted. After adjustment, the knob 39 is released, and the spring 38 pushes the pawl 37 back to its original position and re-engage the ratchet 36.

[0023] To increase the friction between the hand and the first sleeve 1 during carrying of the bracket, multiple anti-slip protrusions 11 are fixedly connected to both the left and right ends of the first sleeve 1. This increased friction prevents slippage when holding the first sleeve 1, allowing the operator to hold and carry the bracket stably and reducing the risk of it falling during transport. When carrying the bracket, the operator's hand contacts the left and right ends of the first sleeve 1. The anti-slip protrusions 11 extend from the surface of the first sleeve 1, increasing the roughness of the contact surface and thus increasing the friction between the hand and the first sleeve 1. This prevents the bracket from slipping during gripping and ensures stability during carrying.

[0024] To facilitate the folding, storage, and carrying of the inclined support assembly 5, a U-shaped bracket is fixedly connected to the bottom of the first sleeve 1, and the bottom of the second sleeve 52 is engaged with the U-shaped bracket.

[0025] It should be noted that many of the standard parts used in this application are available on the market, while non-standard parts can be specially customized. The connection method used in this application is also a very common method in the mechanical field, and will not be described in detail here.

[0026] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
