Description

Technical Field

[0001] The utility model relates to the technical field of industrial cross bars, in particular to a reinforced connecting cross bar structure. Background Art

[0002] ‌Industrial connecting crossbars‌ generally refer to crossbars used to connect or fix different components in industrial equipment or machinery. These crossbars play a vital role in industrial applications, and their main functions include: 1. Connecting and fixing components‌: Industrial connecting crossbars fix different components together through bolts, nuts or other connectors to ensure the stability and safety of the mechanical structure; 2. Transmitting force and load‌: Crossbars transmit force and load through friction and positive pressure to ensure the normal operation of mechanical equipment. For example, the crossbars of a scaffolding transfer the load to the vertical poles through friction to maintain the stability of the structure‌; 3. Structural support‌: Crossbars play a supporting and stabilizing role in industrial structures to prevent structural deformation or collapse. For example, in zinc steel railings, crossbars and vertical poles are interspersed and combined to provide a stable connection between the upper and lower parts;

[0003] Existing industrial cross bars use a telescopic connecting cross bar structure according to different usage requirements. The telescopic industrial cross bar can be conveniently extended when in use and retracted for storage when not in use. It has a quick telescopic storage feature and is convenient for storage. However, due to the structural usage characteristics of the telescopic cross bar, the interior of its fixed rod needs to be hollow to ensure telescopicity. Therefore, the structural strength of the hollow fixed rod often has certain deficiencies and is prone to bending, which affects the service life. For this reason, the utility model proposes a reinforced connecting cross bar structure. Utility Model Content

[0010] Preferably, a limit spring is fixedly installed inside the inner trough body, a limit plug is fixedly installed on the top end of the limit spring, and the limit plug is slidably connected to the inner trough body.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The telescopic connecting cross bar of the utility model can be manually pulled out when in use and can be manually retracted when not in use. It has good rod extensibility, is convenient to use and store, has good use effect, and is easy to use.

[0013] The utility model adopts a double telescopic connection structure at both ends to ensure the telescopic properties of the connecting crossbar. At the same time, the fixing rod adopts a half-hollow structure design, which can effectively avoid the entire rod body from being hollow while ensuring the telescopic properties of the connecting rod. The tail end of the fixing rod is still a solid structure. Therefore, the semi-hollow structure design can effectively improve the structural strength of the tail end of the fixing rod, avoiding the problem of insufficient strength of the rod body caused by being completely hollow.

Since the end reinforcements adopt a trapezoidal structure design and the upper surface of the end reinforcements is higher than the outer end surface of the No. 1 fixing rod, the external forces in the up and down directions will directly act on the end reinforcements. The trapezoidal support legs of the end reinforcements can effectively provide force support for the external forces, avoiding the external forces directly acting on a certain point of the fixing rod, and having the effect of force conduction support, thereby effectively improving the compressive support of the external side of the fixing rod, making the force on the fixing rod more uniform, and having higher structural strength, thereby effectively avoiding bending and deformation of the rod body and improving the service life.

[0026] See also Figure 1-6 The utility model provides an embodiment: a reinforced connecting cross bar structure, including a No. 1 fixing rod 1, a No. 2 fixing rod 3 is provided on one side of the No. 1 fixing rod 1, the No. 1 fixing rod 1 and the No. 2 fixing rod 3 have the same structure and size, the No. 1 fixing rod 1 and the No. 2 fixing rod 3 are arranged in mirror image relative to each other, and an inner slide groove 4 for providing a telescopic space is opened inside the opposite end of the No. 1 fixing rod 1 and the No. 2 fixing rod 3;

[0027] A telescopic link 3 is slidably connected between the inner slide groove 4 of the No. 1 fixed rod 1 and the No. 2 fixed rod 3. The telescopic link 3 is a solid link, which makes it have good structural strength.

[0028] The depth of the inner groove 4 of the No. 1 fixed rod 1 and the No. 2 fixed rod 3 is half the length of the telescopic link 3. This structure allows the two ends of the telescopic link 3 to be retracted into the No. 1 fixed rod 1 and the No. 2 fixed rod 3. The specific state is shown in the attached manual. Figure 6 As shown;

[0029] The utility model adopts a double telescopic connection structure at both ends to ensure the telescopic properties of the connecting crossbar. At the same time, the fixing rod adopts a half-hollow structure design, which can effectively avoid the entire rod body from being hollow while ensuring the telescopic properties of the connecting rod. The tail end of the fixing rod is still a solid structure. Therefore, the semi-hollow structure design can effectively improve the structural strength of the tail end of the fixing rod, avoiding the problem of insufficient strength of the rod body caused by being completely hollow.

[0030] At the same time, in order to strengthen the structure of the No. 1 fixing rod 1 and the No. 2 fixing rod 3, please refer to the attached manual for details. Figure 2 and Figure 5 As shown, strip grooves 5 are formed on the outer walls of the No. 1 fixing rod 1 and the No. 2 fixing rod 3. Several side reinforcement columns 6 are fixedly installed in the strip grooves 5 on both sides by welding. Several end reinforcement members 7 are fixedly installed in the strip grooves 5 at the upper and lower ends by welding. Several side reinforcement columns 6 and end reinforcement members 7 are evenly spaced and distributed around the circumference.

[0031] Further, please refer to the attached manual for details. Figure 5 As shown, the end reinforcement member 7 adopts a trapezoidal structure design, and the upper surface of the end reinforcement member 7 is higher than the outer end surface of the No. 1 fixing rod 1;

[0032] This structural design, through the provision of the side reinforcement column 6, can effectively protect the horizontal sides of the fixing rod from external forces, effectively resist external impact, avoid deformation, and have a good structural reinforcement effect. At the same time, the side reinforcement column 6 can provide a certain strengthening support in the vertical direction, which can effectively improve the compressive support strength of the fixing rod and has good practicality.

[0033] The end reinforcement 7 provided can cooperate with the side reinforcement column 6 to improve the compressive resistance effect in the up and down directions. Since the end reinforcement 7 adopts a trapezoidal structure design, and the upper surface of the end reinforcement 7 is higher than the outer end surface of the No. 1 fixing rod 1, the external force in the up and down directions will directly act on the end reinforcement 7. The trapezoidal support legs of the end reinforcement 7 can effectively provide component support for the external force, avoiding the external force directly acting on a certain point of the fixing rod, and having the effect of force conduction support, thereby effectively improving the compressive support of the outside of the fixing rod, making the fixing rod more evenly stressed, and having higher structural strength, thereby effectively avoiding bending and deformation of the rod body and improving service life.

[0034] In this embodiment, in order to facilitate the fixed limit of the withdrawn telescopic connecting rod 3, a limit hole 8 for extending the limit is opened on the outer wall of the top of the No. 1 fixing rod 1 and the No. 2 fixing rod 3, and an inner groove 9 is opened inside the two ends of the telescopic connecting rod 3. The inner groove 9 adopts a circular groove structure design;

[0035] Furthermore, a limit spring 10 is fixedly installed inside the inner tank body 9, and a limit plug 11 is fixedly installed on the top of the limit spring 10, and the limit plug 11 is slidably connected to the inner tank body 9;

[0036] With this structural design, when the telescopic link 3 is pulled out, the limiting spring 10 in the compressed state inside it will pop out the limiting plug 11, so that the popped-out limiting plug 11 can be inserted into the limiting hole 8 of the fixed rod, thereby completing the withdrawal limit work of the telescopic link 3;

[0037] When retraction is required, the limit plug 11 is manually pressed to compress the limit spring 10 at the tail end of the limit plug 11 and disengage from the limit hole 8. At this time, one end of the telescopic link 3 can be retracted into the corresponding fixed rod to complete the retraction of the telescopic link 3.

[0038] As an optimized technical solution of the present invention, in order to limit the telescopic link 3 in the retracted state and prevent it from sliding out automatically, a tail limiting hole 8 can also be opened at the tail end of the fixed rod located in the inner slide groove 4, so that after the telescopic link 3 is retracted, the limiting plug 11 can be inserted into the limiting hole 8 at the tail end, thereby limiting and fixing the retracted state and preventing the telescopic link 3 from sliding out automatically.

[0039] Working principle: When the utility model is in use, the telescopic connecting rod 3 can be manually pulled out. When the telescopic connecting rod 3 is pulled out, the limiting spring 10 in the compressed state inside it will pop out the limiting plug 11, so that the popped-out limiting plug 11 can be inserted into the limiting hole 8 of the fixed rod, thereby completing the extraction limit work of the telescopic connecting rod 3. The specific extension state is shown in the attached manual. Figure 1 As shown, the normal use of the utility model can be guaranteed;

[0040] When it is necessary to retract, the limiting plug 11 is manually pressed to compress the limiting spring 10 at the tail end of the limiting plug 11 and disengage from the limiting hole 8. At this time, one end of the telescopic connecting rod 3 can be retracted into the corresponding fixed rod to complete the retraction of the telescopic connecting rod 3, thereby facilitating storage. The telescopic connecting cross bar of the utility model can be manually pulled out when in use and manually retracted when not in use. It has good rod extensibility, is convenient for use and storage, has good use effect, and is easy to use.

[0041] At the same time, the utility model adopts a double telescopic connection structure at both ends to ensure the telescopicity of the connecting crossbar. At the same time, the fixing rod adopts a half-hollow structure design, which can effectively avoid the hollow state of the entire rod body while ensuring the telescopicity of the connecting rod. The tail end of the fixing rod is still a solid structure. Therefore, the semi-hollow structure design can effectively improve the structural strength of the tail end of the fixing rod, avoiding the problem of insufficient strength of the rod body caused by the full hollowness.

[0042] The side reinforcement columns 6 provided in the present invention can effectively protect the external forces on both sides of the fixed rod from impact, effectively resist external impact, avoid deformation, and have a good structural reinforcement effect. At the same time, the side reinforcement columns 6 can provide a certain strengthening support in the vertical direction, which can effectively improve the compressive support strength of the fixed rod and have good practicality.

[0043] The end reinforcement 7 provided can cooperate with the side reinforcement column 6 to improve the compressive resistance effect in the up and down directions. Since the end reinforcement 7 adopts a trapezoidal structure design and the upper surface of the end reinforcement 7 is higher than the outer end surface of the No. 1 fixing rod 1, the external force in the up and down directions will directly act on the end reinforcement 7. The trapezoidal support legs of the end reinforcement 7 can effectively provide component support for the external force, avoiding the external force directly acting on a certain point of the fixing rod, and having the effect of force conduction support, thereby effectively improving the compressive support of the outside of the fixing rod, making the fixing rod more evenly stressed, and having higher structural strength, thereby effectively avoiding bending and deformation of the rod body and improving service life.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
