Technical Field
[0001] This utility model relates to the field of anti-fall guide rail technology, specifically a rigid anti-fall guide rail with mortise and tenon structure. Background Technology
[0002] Currently, when workers install, inspect, or maintain lines on power and communication poles and other equipment, they must wear safety belts and then slide the safety belts onto the fall arrest rails on the power and communication poles and other equipment to provide protection.
[0003] For segmented, assembled rigid fall arrestor rails, installation requires individual sections to be attached to power and communication poles and other equipment until adjacent components are fully assembled to form the segmented rigid fall arrestor rail. In the event of a fall, the rail bears a sudden and significant lateral and longitudinal pressure, which may cause the connections between each segment to loosen and detach, leading to a safety accident. Furthermore, when a lower segment of the rigid fall arrestor rail is installed at the bottom of an upper segment, a single person must not only ensure the lower segment remains secure but also tighten the connection, making this extremely difficult and significantly impacting installation efficiency. Therefore, we have introduced a mortise and tenon structure rigid fall arrestor rail. Utility Model Content
[0004] The purpose of this utility model is to provide a rigid anti-fall guide rail with a mortise and tenon structure to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a rigid anti-fall guide rail with mortise and tenon structure, comprising a T-shaped guide rail body, wherein the T-shaped guide rail body comprises a guide rail plate and a connecting plate in the middle of the guide rail plate;
[0006] The connecting plate has a plug-in slot and a plug-in plate at both ends, and the connecting plate has a first M-shaped slot and a second M-shaped slot on the side of both ends, and the plug-in plate has a first V-shaped slot on both sides, and the plug-in slot has a second V-shaped slot on both side walls.
[0007] After the plug plate is inserted into the corresponding plug slot, the snap-fit assembly at the end of the plug plate achieves the initial fixation between the upper and lower adjacent T-shaped guide rail bodies. Finally, the tenon assembly is used to rivet and fix the first tenon formed by the first M-shaped groove and the second M-shaped groove, as well as the second tenon formed by the first V-shaped groove and the second V-shaped groove.
[0008] Preferably, the inner wall of the insertion slot is further provided with an inner groove, and the side of the inner groove is provided with a slot;
[0009] The buckle assembly includes a fixing plate at the end of the plug-in plate and oblique buckles at both ends of the V-shaped reserved groove in the middle of the fixing plate.
[0010] The fixing plate is inserted into the corresponding inner groove, and the angled buckle is fastened in the corresponding slot.
[0011] Preferably, the fixing plate is provided with a first opening, the inner groove is provided with a second opening that mates with the first opening, the plug plate is provided with a third opening, a set of bolts on the tenon assembly extends through the first and second openings and is locked with nuts, and another set of bolts on the tenon assembly extends through the third opening and is locked with nuts.
[0012] Preferably, the tenon assembly includes a first side plate and a second side plate;
[0013] The first side panel includes a first side clamping plate and a first tenon protrusion and a second tenon protrusion fixed on the first side clamping plate;
[0014] The second side panel includes a second side clamping plate and a first tenon groove and a second tenon groove formed on the second side clamping plate;
[0015] The first tenon protrusion extends through the first mortise and then engages with the first mortise groove, and the second tenon protrusion extends through the second mortise and then engages with the second mortise groove.
[0016] Preferably, the first side clamping plate is further provided with a first reserved hole for the protruding bolt to pass through, and the second side clamping plate is also provided with a second reserved hole for the protruding bolt to pass through.
[0017] Compared with existing technologies, the advantages of this invention are as follows: During installation, the snap-fit assembly quickly and initially fixes the lower T-shaped guide rail body to the upper T-shaped guide rail body, preventing the lower T-shaped guide rail body from falling off the bottom of the upper T-shaped guide rail body, thus reducing the positioning difficulty and time cost during installation. This initial fixation facilitates the subsequent connection of the tenon assembly and the tightening of bolts, improving installation efficiency.
[0018] Furthermore, operators can relatively easily disassemble adjacent T-shaped guide rail bodies using the snap-fit assembly, making the disassembly operation more convenient.
[0019] This utility model employs a mortise and tenon structure, such as a first tenon groove formed by a first M-shaped groove and a second M-shaped groove, and a second tenon groove formed by a first V-shaped groove and a second V-shaped groove, in conjunction with a first tenon protrusion, a second tenon protrusion, a first tenon groove, and a second tenon groove. This mortise and tenon structure has excellent seismic resistance, effectively dispersing external forces and preventing rapid structural damage when subjected to vibration or impact. Moreover, the mortise and tenon connection method allows the guide rail to have good stability in all directions, ensuring that the guide rail will not easily shift during use. Compared with simple planar connections, the mortise and tenon structure can provide greater friction and interlocking force, making it less likely for adjacent T-shaped guide rail bodies to shift relative to each other during use, thus ensuring the overall structural stability of the guide rail.

[0033] 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.
[0034] Example:
[0035] Please see Figure 1-12 This utility model provides a technical solution:
[0036] A rigid anti-fall guide rail with mortise and tenon structure includes several sets of T-shaped guide rail bodies that are connected to each other. The T-shaped guide rail body includes a guide rail plate 1 and a connecting plate 2 in the middle of the guide rail plate 1. The guide rail plate 1 and the connecting plate 2 are integrally formed.
[0037] The two ends of the connecting plate 2 are respectively provided with a plug-in groove 7 and a plug-in plate 3. The two sides of the connecting plate 2 are respectively provided with a first M-shaped groove 12 and a second M-shaped groove 18. The two sides of the plug-in plate 3 are provided with a first V-shaped groove 13, and the two side walls of the plug-in groove 7 are provided with a second V-shaped groove 17.
[0038] The inner wall of the insertion slot 7 is also provided with an inner groove 8, and the side of the inner groove 8 is provided with a slot 20;
[0039] The snap-fit assembly includes a fixing plate 4 at the end of the plug-in plate 3 and oblique snap-fits 16 at both ends of the V-shaped reserved groove 15 in the middle of the fixing plate 4.
[0040] The fixing plate 4 is inserted into the corresponding inner groove 8, and the angled buckle 16 is snapped into the corresponding slot 20.
[0041] The snap-fit assembly consists of a fixing plate 4, a V-shaped pre-drilled groove 15, and an angled snap fastener 16. During installation, the engagement of the angled snap fastener 16 with the groove 20 quickly and initially secures the lower T-shaped guide rail body to the upper T-shaped guide rail body, preventing the lower T-shaped guide rail body from falling off the bottom of the upper T-shaped guide rail body, thus reducing positioning difficulty and time costs during installation. This initial fixation facilitates subsequent tenon assembly connection and bolt tightening, improving installation efficiency.
[0042] When the fixing plate 4 is inserted into the corresponding inner groove 8, the angled buckle 16 needs to engage with the slot 20. The presence of the V-shaped pre-reserved groove 15 gives the fixing plate 4 a certain degree of elastic deformation capability. During insertion, the angled buckle 16 is squeezed by the inner wall of the inner groove 8. At this time, the V-shaped pre-reserved groove 15 allows the fixing plate 4 to undergo a certain degree of elastic deformation, enabling the angled buckle 16 to smoothly enter the slot 20. After insertion, the fixing plate 4 returns to its elastic deformation, and the angled buckle 16 is firmly locked in the slot 20, achieving the initial fixation of the adjacent T-shaped guide rail body.
[0043] The V-shaped pre-drilled groove 15 helps to disperse the stress on the angled buckle 16 during the buckling process. When the angled buckle 16 is subjected to external force, the V-shaped pre-drilled groove 15 can evenly distribute the stress to other parts of the fixing plate 4, avoiding stress concentration that could damage or loosen the angled buckle 16. This ensures a more stable and reliable buckling connection between the angled buckle 16 and the slot 20, and ensures that adjacent T-shaped guide rail bodies can maintain relative positional stability during the initial fixing stage.
[0044] Because the V-shaped pre-drilled groove 15 provides elasticity to the fixing plate 4, operators can relatively easily apply a certain external force to the angled buckle 16 during installation and disassembly, causing it to enter or disengage from the groove 20. This makes the initial fixing and disassembly of adjacent T-shaped guide rail bodies more convenient, improving the efficiency of installation and maintenance.
[0045] After the plug plate 3 is inserted into the corresponding plug slot 7, the snap-fit assembly at the end of the plug plate 3 is used to achieve the initial fixation between the upper and lower adjacent T-shaped guide rail bodies. Finally, the tenon assembly is used to rivet and fix the first tenon 22 formed by the first M-shaped groove 12 and the second M-shaped groove 18 and the second tenon 21 formed by the first V-shaped groove 13 and the second V-shaped groove 17.
[0046] The tenon assembly includes a first side plate 9 and a second side plate 5;
[0047] The first side panel 9 includes a first side clamping plate 92 and a first tenon protrusion 94 and a second tenon protrusion 93 fixed on the first side clamping plate 92.
[0048] The second side panel 5 includes a second side clamping plate 52 and a first tenon groove 54 and a second tenon groove 53 opened on the second side clamping plate 52.
[0049] The first tenon protrusion 94 extends through the first mortise 22 and is inserted into the first tenon groove 54, and the second tenon protrusion 93 extends through the second mortise 21 and is inserted into the second tenon groove 53.
[0050] The guide rail employs a mortise and tenon structure, such as the first tenon 22 formed by the first M-shaped groove 12 and the second M-shaped groove 18, and the second tenon 21 formed by the first V-shaped groove 13 and the second V-shaped groove 17, which are matched with the first tenon protrusion 94, the second tenon protrusion 93, the first tenon groove 54, and the second tenon groove 53. This mortise and tenon structure has good seismic performance, effectively dispersing external forces and preventing rapid structural damage when subjected to vibration or impact. Moreover, the mortise and tenon connection method allows the guide rail to have good stability in all directions, ensuring that the guide rail will not easily shift during use.
[0051] The first tenon protrusion 94 is inserted into the first mortise 22 formed by the first M-shaped groove 12 and the second M-shaped groove 18, and the second tenon protrusion 93 is inserted into the second mortise 21 formed by the first V-shaped groove 13 and the second V-shaped groove 17. This tenon and mortise joint structure greatly enhances the connection strength between adjacent T-shaped guide rail bodies. The tight fit between the tenon and the mortise effectively resists external forces in various directions, such as tension, compression, and shear forces. Compared to simple planar connections, the tenon and mortise structure provides greater friction and interlocking force, making it less likely for adjacent T-shaped guide rail bodies to shift relative to each other during use, thus ensuring the overall stability of the guide rail structure.
[0052] The tenon protrusion and mortise provide excellent positioning and guiding. During installation, the first tenon protrusion 94 can be accurately inserted into the corresponding first mortise 22 and first tenon groove 54, and the second tenon protrusion 93 can be accurately inserted into the corresponding second mortise 21 and second tenon groove 53, providing a precise positioning reference for the installation of adjacent T-shaped guide rail bodies. This helps ensure the installation accuracy of the guide rails, enabling them to maintain straightness and perpendicularity after installation and ensuring their normal operation.
[0053] Although mortise and tenon joints provide a strong connection, the tenon can be relatively easily removed from the mortise through proper handling when disassembly and repair are needed. Compared to some non-removable connection methods such as welding or riveting, the removability of mortise and tenon joints makes it easier to repair and replace parts when the guide rail malfunctions or needs replacement, reducing maintenance costs and time.
[0054] The fixing plate 4 is provided with a first opening 14, the inner groove 8 is provided with a second opening 19 that mates with the first opening 14, the plug plate 3 is provided with a third opening 11, a set of bolts 10 on the tenon assembly extends through the first opening 14 and the second opening 19 and is locked with nuts 6, and another set of bolts 10 on the tenon assembly extends through the third opening 11 and is locked with nuts 6.
[0055] The first side clamping plate 92 is also provided with a first reserved hole 91 for passing through the protruding bolt 10, and the second side clamping plate 52 is also provided with a second reserved hole 51 for passing through the protruding bolt 10.
[0056] The reliability of the guide rail connection is further enhanced by tightening the various components with bolts 10 and nuts 6. The bolt connection can be adjusted in tightness as needed to ensure a tight connection and prevent safety hazards caused by loosening during long-term use. At the same time, the bolt connection facilitates disassembly and maintenance, allowing for convenient replacement and repair if problems occur during use.
[0057] Specifically, during use, the initial connection is as follows: When installing the guide rail, insert the upper plug-in plate 3 of the connecting plate 2 of the lower T-shaped guide rail body upwards into the corresponding plug-in groove 7 at the lower end of the connecting plate 2 of the upper T-shaped guide rail body. Simultaneously, the fixing plate 4 at the end of the plug-in plate 3 inserts into the inner groove 8 on the top wall of the plug-in groove 7. At this time, the angled buckle 16 on the fixing plate 4 will engage within the slot 20, achieving initial fixation between adjacent upper and lower T-shaped guide rail bodies. This initial fixation method ensures the guide rail remains relatively stable during further installation.
[0058] Tenon assembly connection: After initial fixing, a more secure connection is achieved using a tenon assembly. The tenon assembly consists of a first side panel 9 and a second side panel 5. The first tenon protrusion 94 on the first side panel 9 passes through the first mortise 22 formed by the first M-shaped groove 12 and the second M-shaped groove 18 and then engages in the first tenon groove 54 of the second side panel 5; the second tenon protrusion 93 passes through the second mortise 21 formed by the first V-shaped groove 13 and the second V-shaped groove 17 and then engages in the second tenon groove 53.
[0059] Bolt tightening: After the initial connection of the tenon assembly is completed, bolts 10 are used for final tightening. One set of bolts 10 passes sequentially through the first reserved hole 91 of the first side clamping plate 92, the first opening 14 of the fixing plate 4, the second opening 19 of the inner groove 8, and the second reserved hole 51 of the second side clamping plate 52, and is then locked with nuts 6; another set of bolts 10 passes sequentially through the first reserved hole 91 of the first side clamping plate 92, the third opening 11 of the plug-in plate 3, and the second reserved hole 51 of the second side clamping plate 52, and is then locked with nuts 6. The tightening of bolts and nuts makes the entire connection structure more robust, ensuring that the guide rail will not loosen during use.
[0060] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
