Description

1 TARIFF LOCKING MECHANISM FOR TRAILER SLIDING DOORS Technical Area The invention relates to a sliding rear design for trailer-semi-trailer vehicles used in road transport. a mechanical locking mechanism used when mechanically locking the door 5 It is related to. State of the Art In road transport, trailers and semi-trailers are used to transport cargo safely. These are important elements for transporting the vehicles safely. Sliding rear doors facilitate loading and unloading of these vehicles. It is a structure that facilitates unloading operations. 10 The sliding rear doors are equipped with a locking mechanism, and these mechanisms... They are available in manual or automatic locking systems. In manual locking, the user... After closing the door, lock it using the handle or button. This process... It guarantees that the door remains fixed in place and will not open. Automatic locking is also important. When the door closes, the mechanism automatically engages and locks the door securely. It closes in this way. In current technology, trailer-semi-trailer vehicles have a rear section located at the back of the vehicle. mechanical lock systems used in addition to the existing lock systems of sliding doors It is located there. Even if the user unlocks the locks used on the vehicle door, this lock remains open. The sliding door will not lift up. This locking system, also called a concealed lock, has these 20 features. Someone unaware of the lock's existence cannot open the door. This hidden feature is present in current technology. The disadvantage of the lock is its complex and cumbersome structure. For the locking system... It is too long and unnecessarily increases the weight of the vehicle. This is both cost-effective. It also creates problems in terms of user ergonomics. In conclusion, due to the negative aspects described above and the current solutions regarding issue 25 Due to its shortcomings, an improvement in the relevant technical field is necessary. It has been made. The purpose of the invention 2 The invention was created by drawing inspiration from existing situations and overcoming the aforementioned drawbacks. It aims to solve the problem. The main purpose of the invention is to create a sliding mechanism located at the rear of trailer and semi-trailer vehicles. The goal is to develop a mechanical lock that allows the door to be locked. Another aim of the invention is to offer an ergonomic and cost-effective mechanical lock. 5 Another aim of the invention is to offer a lightweight mechanical lock that does not increase the weight of the vehicle. To fulfill the purposes described above, the invention is a trailer-semi-trailer trailer. a device used to mechanically lock the sliding rear door of vehicles It has a mechanical locking mechanism, the feature of which is;  The rear sliding door of the vehicle, which carries the elements of the mechanism, is located at the bottom. a lock mechanism that connects to the bottom of the door outer casing,  It has a monolithic structure with the outer casing, located inside the outer casing. an inner casing that accommodates the locking mechanism,  By touching the sliding rear door, the sliding rear door will lock. 15 a locking tongue that provides and  It has a one-piece structure with the locking tongue, the sliding rear of the locking tongue the movement that allows the door to be locked a locking lever It includes. 20 The structural and characteristic features and all the advantages of the invention are given in the figures below. This becomes clearer thanks to the detailed explanation written with references to these figures. This will be understood as such, and therefore the evaluation will also take these forms and detailed explanations into account. This should be done taking that into consideration. Figures That Will Help Understand the Discovery 25 Figure 1 is a top perspective view of the mechanical lock that is the subject of the invention. Figure 2 shows the appearance of the mechanical lock after it has been broken open. 3 Figure 3 shows a bottom view of the mechanical lock that is the subject of the invention. Figure 4 shows the mechanical lock, the subject of the invention, mounted on the underside of the vehicle. Figure 5 shows a representative view of the locking mechanism from the rear of the trailer. Explanation of Part References 1. Locking mechanism 5 10. Outer casing 20. Inner body 21. Keyhole 22. Body housing 23. Connection holes 10 30. Locking tongue 40. Locking lever 50. Sliding rear door Detailed Description of Find In this detailed explanation, the locking mechanism (1) which is the subject of the invention is preferred 15 Their structures are explained solely to facilitate a better understanding of the subject. The sliding rear of trailer-semi-trailer vehicles is shown in Figures 1 and 3. The invention's mechanical locking mechanism is used when the door (50) is mechanically locked. The locking mechanism (1) in its most basic form; an outer body (10), an inner body (20), a locking It consists of a tongue (30) and a locking lever (40). 20 The outer casing (10) mentioned in the locking mechanism (1) is the element of the mechanism. carry it on top and lock it on the underside of the lower sliding rear door (50) of the vehicle. It provides the connection of the mechanism (1). The mentioned inner body (20) is the outer body. It is connected and has a monolithic structure by means of (10). However 4 The inner body (20) is located inside the outer body (10) and is the bearing for the locking operation. is doing. A locking tongue (30) to provide the locking function in the locking mechanism (1) It is located. The locking tongue holds by contacting the sliding rear door (50) and the sliding It ensures the rear door (50) is locked. Here, the necessary 5 is placed on the locking tongue (30). There is a locking lever (40) that provides mechanical drive. The aforementioned locking lever (40) is welded with a locking tongue and has a monolithic structure and the locking tongue (30) is sliding It enables the rear door (50) to be moved in order to lock it. In one application of the invention, the locking mechanism (1) consists of the inner body (20) of the locking tongue (30) 10 It can move horizontally forward or backward towards the sliding rear door (50) inside. It includes a lock hole (21) configured on the inner body (20) which provides. together with the locking lever (40) fixed inside the inner body (30) in the locking position. and the locking tongue (30) must remain in constant contact with the sliding rear door (50). It has a body housing (22) which enables it to be. It also has an inner body (20) and a locking mechanism. 15 located on the lever (40) and the mechanism locking the sliding rear door (50) in the case of alignment, the mechanism is exposed to an external influence mounting holes that allow the use of an external padlock to prevent blocking (23) It contains. The working principle of the locking mechanism (1) which is the subject of the invention is as follows: The locking mechanism of the invention (1) is located at the lower left rear of the vehicle as shown in Figure 4. It is located in that area. Because it has a hidden lock feature, it is not visible from the outside. It is not visible. To activate or deactivate the lock, you must bend down under the vehicle and Intervention must be made from below. The locking mechanism (1) must be made from below the vehicle to be intervened. It is mounted onto the structure. The connection mechanism to the vehicle forms the outer frame. and is provided by the outer housing (10) which holds the parts together. Locking lever (40) 25 The locking tongue (30) moves horizontally back and forth inside the inner body (20) relative to the vehicle floor. It does this. When the locking lever (40) pushes the locking tongue (30), it provides the locking function. It is fitted into the housing (22). Thus, locking is possible without external interference. The lever (40) is held in a fixed position. At the moment of locking and the locking lever (40) When the body is seated in the housing (22), the mounting holes (23) are aligned. 30 In this case, if desired, the operator can attach a hanger lock to the connection holes (23). the locking lever (40) coming out of the housing (22) by external intervention It can be blocked. The locking lever (40) on the body is required to open the sliding rear door (50). It should be lifted out of its housing (22) and the locking tongue (30) should be slid into the rear door. (50) contact must be cut off.
