Description

Technical Field

[0001] This utility model relates to the field of impact device technology, and in particular to a lamp impact device. Background Technology

[0002] A lamp impact device is a device that applies impact force to a lamp. It is often used to test the impact resistance of lamps to ensure that they can withstand mechanical impacts without being damaged during transportation, installation or use.

[0003] Existing lighting impact devices typically include an impact ball and a fixing plate for fixing the impact ball. By maintaining a certain distance between the lighting fixture (light fixture housing) and the fixing plate, the fixing effect of the fixing plate on the impact ball is eliminated, allowing the impact ball to fall onto the lighting fixture, thus completing the impact and testing work.

[0004] Currently, in order to ensure that the impact ball can accurately land on the lamp, a vertical cylinder is also installed on the fixed plate. The vertical cylinder is detachably connected to the fixed plate. This means that when installing the impact ball, the staff also need to remove the vertical cylinder from the fixed plate and hold the vertical cylinder until the impact ball is installed. Then, the vertical cylinder is reinstalled on the fixed plate, which makes the use of the impact device somewhat inconvenient. Utility Model Content

[0005] The main purpose of this utility model is to provide a lighting impact device, which aims to solve the problem in related technologies where the vertical cylinder needs to be held by hand when installing the impact ball, resulting in limited flexibility in the use of the impact device.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A lighting impact device includes a mounting plate, a vertical cylinder, and an impact ball. The mounting plate has a receiving cavity for accommodating the impact ball. The distance between the bottom of the receiving cavity and the end of the mounting plate close to the vertical cylinder is greater than the diameter of the impact ball. The vertical cylinder is rotatably connected to the mounting plate. The vertical cylinder has a rotating shaft for rotatably connecting to the mounting plate. There is a gap between the central axis of the rotating shaft and the central axis of the vertical cylinder and the central axis of the mounting plate.

[0008] Furthermore, the mounting plate is equipped with a limiting plate.

[0009] Furthermore, the longitudinal section of the rotating shaft has a "T" shaped structure.

[0010] Furthermore, the mounting plate is provided with a locking pin for fixing the vertical cylinder, and the locking pin is slidably connected to the mounting plate.

[0011] Furthermore, the vertical cylinder is provided with an abutment groove for cooperating with the locking pin.

[0012] Furthermore, a mating plate is provided at the end of the locking pin away from the vertical cylinder, and several elastic elements are provided between the mating plate and the mounting plate.

[0013] Furthermore, the end of the locking pin away from the impact ball is provided with a linkage inclined surface; the width of the end face of the locking pin close to the vertical cylinder is smaller than the width of the end face of the locking pin away from the vertical cylinder.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] This utility model's technical solution achieves a detachable connection between the vertical cylinder and the mounting plate by rotating them. Specifically, the vertical cylinder has a rotating shaft, which connects it to the mounting plate. A gap exists between the central axis of the rotating shaft, the central axis of the vertical cylinder, and the central axis of the mounting plate. Rotating the vertical cylinder allows it to detach from the mounting plate, eliminating any interference with the installation of the impact ball. After the impact ball is installed, the vertical cylinder is returned to its original position. During this process, the vertical cylinder, thanks to its connection to the mounting plate, can be suspended below it, eliminating the need for workers to hold the vertical cylinder while installing the impact ball. Compared to traditional lighting impact devices, this method is more convenient and flexible.

[0016] Meanwhile, the cavity depth of the receiving cavity on the mounting plate for installing and accommodating the impact ball is greater than the diameter of the impact ball, so that the impact ball will not form protrusions or bumps on the surface of the mounting plate after being installed in the mounting plate, thereby avoiding interference between the impact ball and the vertical cylinder and the mounting plate.

[0027] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0029] Example 1

[0030] like Figure 1 , Figures 4-5 As shown, this embodiment proposes a lamp impact device, which mainly includes a mounting plate 1, a vertical cylinder 2, and an impact ball 3. The mounting plate 1 is provided with a receiving cavity 11 for accommodating the impact ball 3. In this embodiment, the impact ball 3 is preferably fixed in the receiving cavity 11 by a magnetic structure such as an electromagnet. The specific way of fixing the impact ball 3 in the mounting plate 1 should be determined according to the actual mounting plate 1 used, and will not be described in detail in this embodiment.

[0031] The vertical cylinder 2 is rotatably connected to the mounting plate 1. Specifically, the vertical cylinder 2 is equipped with a rotating shaft 21 for rotatably connecting to the mounting plate 1. There is a gap between the central axis of the rotating shaft 21 and the central axis of both the vertical cylinder 2 and the mounting plate 1. Thus, by applying a force to the vertical cylinder 2, it can be made to rotate eccentrically relative to the mounting plate 1, causing the vertical cylinder 2 to detach from the mounting plate 1. This eliminates the obstruction and interference of the vertical cylinder 2 on the installation of the impact ball 3. After the impact ball 3 is installed, the vertical cylinder 2 is reset, completing the installation of the impact ball 3.

[0032] Correspondingly, the distance between the bottom of the receiving cavity 11 and the end of the mounting plate 1 that is close to the vertical cylinder 2 is greater than the diameter of the impact ball 3, so as to avoid the formation of protrusions or bumps on the surface of the mounting plate 1 after the impact ball 3 is installed, thereby avoiding the impact ball 3 from affecting the normal fit between the vertical cylinder 2 and the mounting plate 1.

[0033] Meanwhile, due to the rotational connection between the vertical cylinder 2 and the mounting plate 1, the vertical cylinder 2 can be constrained, so that the staff does not need to hold the vertical cylinder 2 during the installation of the impact ball 3, which greatly improves the ease of use and flexibility of this embodiment.

[0034] Correspondingly, the longitudinal section of the rotating shaft 21 is a "T" shaped structure, that is, a limiting block is provided between the rotating shaft 21 and the mounting plate 1. Through the limiting effect of the limiting block, the vertical cylinder 2 is prevented from detaching from the mounting plate 1 (the rotating shaft 21 detaches from the rotating hole on the mounting plate 1). The limiting block is preferably set on the end face of the rotating shaft 21 by welding, which ensures the structural stability of the overall structure of the rotating shaft 21. After the limiting block is fixedly set on the rotating shaft 21, when the limiting block is subjected to excessive force or the service life of the connection structure between the limiting block and the rotating shaft 21 is exhausted, the limiting block can be directly re-welded on the end face of the rotating shaft 21 to quickly repair this embodiment, thereby ensuring the normal operation of this embodiment.

[0035] like Figures 2-6 As shown, the mounting plate 1 is provided with a limiting plate 12. The presence of the limiting plate 12 helps to prevent the vertical cylinder 2 from displacing too far during the reset process, which would affect its reset accuracy and thus improve the reset efficiency of the vertical cylinder 2 (that is, when the vertical cylinder 2 and the limiting plate 12 come into contact with each other, it means that the vertical cylinder 2 has been reset).

[0036] Meanwhile, the mounting plate 1 is provided with a locking pin 4 for fixing the vertical cylinder 2. The locking pin 4 is slidably connected to the mounting plate 1, that is, the mounting plate 1 is provided with a sliding hole for the locking pin 4 to slide. The central axis of the sliding hole is perpendicular to the horizontal plane. In this way, the locking pin 4 located in the sliding hole can be reset under the action of gravity, so that the locking pin 4 can maintain a state of mutual contact with the reset vertical cylinder 2. By moving the locking pin 4, the locking pin 4 and the vertical cylinder 2 are made to abut against each other. Thus, during the operation of this embodiment, the vertical cylinder 2 is displaced by force, causing the impact ball 3 to deviate from the expected movement trajectory, thus ensuring the stable operation of the impact work.

[0037] The vertical cylinder 2 is provided with an abutting groove 22 for cooperating with the locking pin 4. The presence of the abutting groove 22 allows the locking pin 4 to abut against the vertical cylinder 2 in a surface contact manner, thereby increasing the contact area between the two and enabling the locking pin 4 to more effectively and reliably constrain the vertical cylinder 2.

[0038] A mating plate 41 is provided at the end of the locking pin 4 away from the vertical cylinder 2. The mating plate 41 is preferably integrally formed with the locking pin 4 to ensure the stability of the connection between the two. The presence of the mating plate 41 can also limit the locking pin 4, preventing the locking pin 4 from dislodging from the sliding hole under the action of gravity. Several elastic elements 5 are provided between the mating plate 41 and the mounting plate 1. The two ends of each elastic element 5 are fixedly connected to the mating plate 41 and the mounting plate 1, that is, the presence of each elastic element 5 restricts the movement distance of the locking pin 4, preventing the locking pin 4 from dislodging from the mounting plate 1 when the worker lifts the locking pin 4 (to remove the restraining effect of the locking pin 4 on the vertical cylinder 2 and to rotate the vertical cylinder 2), effectively ensuring the stability of the overall structure of this embodiment.

[0039] Example 2

[0040] Based on Example 1, such as Figure 7 As shown, in this embodiment, the end of the locking pin 4 away from the impact ball 3 is provided with a linkage inclined surface 42; the width of the end face of the locking pin 4 close to the vertical cylinder 2 is smaller than the width of the end face of the locking pin 4 away from the vertical cylinder 2. With the presence of the linkage inclined surface 42, when the vertical cylinder 2 comes into contact with the locking pin 4, the contact force can be converted into a force that pushes the locking pin 4 upward, so that the locking pin 4 automatically avoids the vertical cylinder 2 (the reset operation of the vertical cylinder 2), thereby eliminating the need for the operator to lift the locking pin 4 during the reset process of the vertical cylinder 2, which facilitates the use of this embodiment.
