Observing construction vehicles in operation is awe-inspiring, showcasing the power of machinery and technology. They are used for transportation, excavation, emergency repairs, and even combat.

[0003] To record the machine's working time from start to stop, helping users calculate machine output and understand its operation, timers are typically installed inside engineering vehicles. These timers are usually installed within the vehicle's cargo compartment. During operation, the vehicle vibrates, and the timer's wiring is generally secured by two contact points and a screw and nut. However, the nut can come loose during prolonged vibration, causing instability in the timer's wiring. To address this issue, a timer protection structure is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a protective structure for a timer, which solves the problem that timers are generally installed inside engineering vehicles. During the operation of engineering vehicles, vibrations will occur. The wiring of the timer is usually achieved by two contacting contacts and then being fixed by screws and nuts. However, the nuts may fall off during long-term vibration, resulting in unstable wiring of the timer.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a protective structure for a timer, comprising a timer body, a clamping seat, and a connecting wire. A plurality of first connecting pieces are fixedly connected to the rear surface of the timer body. One end of the connecting wire is fixedly connected to a second connecting piece. A pressure rod is fixedly connected to the top surface of the inner wall of the clamping seat, and a pressure ring is fixedly connected to the bottom end of the pressure rod. A limit rod is fixedly connected to the bottom surface of the inner wall of the clamping seat. The first and second connecting pieces are both mounted on the circumferential side of the limit rod. A rotating shaft is fixedly connected to one side of the timer body. A torsion spring and a clamping plate are connected to the circumferential side of the rotating shaft. The clamping plate and the clamping seat are both fixedly connected to the torsion spring. A plurality of slots are provided on one side of the timer body, and insert rods are installed in the slots. The insert rods are fixedly connected to the clamping plate.

[0007] Preferably, sealing gaskets are adhered to both sides of the timer body.

[0008] Preferably, the insertion rod slides into the slot.

[0009] Preferably, the clamping plate is rotatably connected to the rotating shaft, and the clamping seat is made of elastic plastic.

[0010] Preferably, a plurality of elastic metal sheets are fixedly connected to the peripheral side of the clamping seat.

[0011] Preferably, both the first and second contact plates are slidably engaged with the limiting rod, and the first and second contact plates are electrically connected.

[0012] Preferably, the pressure ring is sleeved on the circumferential side of the limiting rod, and the pressure ring and the limiting rod are in sliding engagement.

[0013] This utility model has the following beneficial effects:

[0014] This invention features a clamping seat, a clamping plate, a pressure ring, and a limiting rod. The clamping plate is rotated; the clamping seat, made of elastic plastic and C-shaped, can be opened to allow two contact pieces to fit around the limiting rod. The clamping seat is then returned to its original position, aligning with the limiting rod. The pressure ring, made of rubber, effectively absorbs vibration, preventing the contact pieces from detaching due to vibration. Under the action of a torsion spring, the clamping plate resets, and the insertion rod is inserted into the slot to fix the clamping plate. This provides a supporting force to the timer body from the side, making the clamping seat more stable. An elastic metal sheet provides a supporting force to the timer body from the other side, effectively preventing the wiring from coming loose due to vibration. A sealing gasket seals both sides of the clamping seat, preventing dust from falling onto the contact pieces and causing poor contact.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0024] Please see Figure 1-4 As shown, this utility model is a timer protection structure, including a timer body 1, a clamping seat 2, and a connecting wire 3. Sealing gaskets 10 are glued to both sides of the timer body 1. By setting the sealing gaskets 10, the two sides of the clamping seat 2 can be sealed to prevent dust from falling on the connecting pieces and causing poor contact. Several first connecting pieces 4 are fixedly connected to the rear surface of the timer body 1. One end of the connecting wire 3 is fixedly connected to a second connecting piece 5. Several elastic metal pieces 6 are fixedly connected to the peripheral side of the clamping seat 2. The first connecting pieces 4 and the second connecting pieces 5 are both slidably engaged with the limiting rod 13. The first connecting pieces 4 and the second connecting pieces 5 are electrically connected. A pressure rod 11 is fixedly connected to the top surface of the inner wall of the clamping seat 2. A pressure ring 12 is fixedly connected to the bottom end of the pressure rod 11. A limiting rod 13 is fixedly connected to the bottom surface of the inner wall of the clamping seat 2. The first connecting pieces 4 and the second connecting pieces 5 are both installed on the peripheral side of the limiting rod 13.

[0025] A rotating shaft 7 is fixedly connected to one side of the timer body 1. A torsion spring 8 and a clamping plate 9 are connected to the circumferential side of the rotating shaft 7. The clamping plate 9 and the clamping seat 2 are both fixedly connected to the torsion spring 8. Several slots are provided on one side of the timer body 1. Insert rods 14 are installed in the slots and slide with the slots.

[0026] The insertion rod 14 is fixedly connected to the clamping plate 9. By setting the clamping seat 2, clamping plate 9, pressure ring 12 and limiting rod 13, the clamping plate 9 is rotatably connected to the rotating shaft 7. The clamping seat 2 is made of elastic plastic. When the clamping plate 9 is rotated, the clamping seat 2, which is made of elastic plastic and has a C-shaped structure, can be pried open. The two contact pieces are then placed on the periphery of the limiting rod 13. Then the clamping seat 2 is restored. At this time, the position of the pressure ring 12 is adapted to the position of the limiting rod 13. The pressure ring 12 is placed on the periphery of the limiting rod 13 and can press the two contact pieces tightly. The pressure ring 12 is made of rubber, which can effectively absorb vibration and prevent the two contact pieces from falling off due to vibration.

[0027] Under the action of the torsion spring 8, the clamping plate 9 is reset, and the insertion rod 14 is inserted into the slot to fix the clamping plate 9, so that the clamping plate 9 provides a clamping force to the timer body 1 from the side, making the clamping seat 2 clamp more stable. The elastic metal sheet 6 can provide a clamping force to the timer body 1 from the other side, which can effectively prevent the timer body 1 from falling off due to vibration. The pressure ring 12 is sleeved on the circumferential side of the limiting rod 13, and the pressure ring 12 and the limiting rod 13 slide together.

[0028] like Figure 1-4 As shown, the method of using a timer protection structure of this utility model is as follows: When using this utility model, the clamping seat 2 is made of elastic plastic and has a C-shaped structure, which can be pried open. The two contact plates are then placed around the periphery of the limiting rod 13. The clamping seat 2 is then restored. At this time, the position of the pressure ring 12 is adapted to the position of the limiting rod 13. The pressure ring 12 is placed around the periphery of the limiting rod 13 and can press the two contact plates tightly. The pressure ring 12 is made of rubber, which can effectively absorb vibration and prevent the two contact plates from being damaged due to vibration. If the clamping plate 9 falls off, it will reset under the action of the torsion spring 8. The insertion rod 14 will be inserted into the slot to fix the clamping plate 9, so that the clamping plate 9 provides a holding force to the timer body 1 from the side, making the clamping seat 2 more stable. The elastic metal sheet 6 can provide a holding force to the timer body 1 from the other side, which can effectively prevent the wiring of the timer body 1 from falling off due to vibration. Then, the sealing gasket 10 is glued on to seal both sides of the clamping seat 2, preventing dust from falling on the contact plate and causing poor contact.
