[0023] It should be noted that, in the absence of conflict, the embodiments in the present application and the features described in the embodiments may be combined with each other. The present application is further described in detail below in conjunction with the drawings and specific embodiments.
[0024] As attached Figure 1 To Attachment Figure 7 As shown, a quick-lock connection structure of a lamp comprises a connecting frame 1, a locking member 2, a disc spring assembly 3 and a matching member 4; the locking member 2 comprises a connecting portion 21 and a limiting portion 22 fixedly connected to one end of the connecting portion 21, a bayonet 23 is fixedly arranged at the other end close to the connecting portion 21 or at the end of the other end of the connecting portion 21, the disc spring assembly 3 is sleeved on the connecting portion 21 and is located between the limiting portion 22 and the bayonet 23, the matching member 4 is used to be fixedly connected to the lamp body 5, the connecting frame 1 is provided with a first opening 11 for the bayonet 23 to pass through, and the bayonet 23 on the locking member 2 passes through the first opening 11 and is engaged with the lamp body 5. The matching piece 4 is locked in cooperation, at which time the disc spring assembly 3 is respectively squeezed with the limiting part 22 and the connecting frame 1 on the locking piece 2 so that the connecting frame 1 is fixedly connected to the lamp body 5. Since the disc spring assembly 3 has a certain elastic force, it can play a buffering role to prevent the connection structure from breaking due to excessive impact force. At the same time, the elastic deformation force generated by the disc spring assembly 3 during squeezing keeps the locking piece 2 and the matching piece 4 in a locked state and is not prone to loosening. Therefore, the quick-lock connection structure has the characteristics of high rigidity, strong buffering and vibration absorption ability, and the ability to withstand large loads with small deformation. It is also easy to use, easy to repair and replace, economical, and highly safe.
[0025] As attached Figure 4As shown, the disc spring assembly 3 includes a plurality of disc spring leaves, and the combination of the plurality of disc spring leaves is any one of a superimposed combination, a matched combination and a composite combination. The number of disc spring leaves is proportional to the load, and the user can select the combination according to the design requirements.
[0026] As attached Figure 2 and attached Figure 6 As shown, the matching piece 4 is provided with a second opening 41 for the bayonet 23 to pass through, and the matching piece 4 is provided with raised edges 42 located on both sides of the second opening 41 and symmetrical about the center of the second opening 41, and the raised edge 42 has two peak sections 421 and a valley section 422 located between the two peak sections 421, and an extension section 423 extending obliquely from the top end to the bottom end of the peak section 421 and along the circumferential direction of the matching piece 4 is connected on the side of one of the peak sections 421 away from the valley section 422, and the bayonet 23 passes through the first openings 11, After the second opening 41, the connecting portion 21 is linked with the bayonet 23 to rotate so that the bayonet 23 passes through the extension section 423 and the peak section 421 and is clamped in the valley section 422. Specifically, the valley section 422 is a groove. Furthermore, the extension section 423 has a certain inclination. During the locking process, the bayonet 23 can slide from low to high along the extension section 423 through the extension section 423 to the top of the peak section 421, and then be clamped in the valley section 422. At the same time, since the disc spring assembly 3 has a certain elastic force, the bayonet 23 can always be clamped in the valley section 422 in the absence of external force to prevent loosening.
[0027] As attached Figure 2 and attached Figure 6As shown, the connecting portion 21 is sleeved with a lock card 6 located between the connecting frame 1 and the bayonet 23, the maximum diameter of the lock card 6 is larger than the diameter of the first opening 11, the lock card 6 is provided with a third opening 61 for the bayonet 23 to pass through, and the lock card 6 is relatively provided with at least one pair of bent elastic portions 62 located in the third opening 61, the spacing between the bent elastic portions 62 is gradually shortened along the axial direction of the lock card 6, and the minimum spacing between the bent elastic portions 62 is smaller than the diameter of the bayonet 23. Preferably, due to the presence of a bent elastic portion 62, the bent elastic portion 62 has a A certain elasticity, the maximum spacing between the bent elastic parts 62 can also be slightly smaller than the diameter of the bayonet 23. Under the action of external force, the bayonet 23 can be inserted into the third opening 61 along the direction in which the spacing between the bent elastic parts 62 changes from large to small. However, it is best that the maximum spacing between the bent elastic parts 62 is larger than the diameter of the bayonet 23. After the connecting frame 1, the locking member 2 and the disc spring assembly 3 are assembled together to form a modular assembly, the locking card 6 can effectively prevent the locking member 2 from escaping from the first opening 11. When the lamp body is assembled, the pre-completed modular assembly can be directly installed on the lamp body, which can greatly increase the assembly efficiency.
[0028] As attached Figure 1 and attached Figure 2 As shown, a knob handle 24 is fixedly provided on the limiting portion 22 , and the knob handle 24 can be locked with the matching member 4 through the connecting portion 21 and the locking pin 23 .
[0029] As attached Figure 7 and attached Figure 8 As shown, at least two pairs of clamping holes 51 are provided on the lamp body 5, and the connecting frame 1 is provided with a clamping protrusion 12 that is plugged into and fits with any pair of the clamping holes 51. The clamping holes 51 and the clamping protrusion 12 cooperate to enable the connecting frame 1 to be quickly positioned and installed on the lamp body.
[0030] As attached Figure 7 and attached Figure 8 As shown, the connecting straight line between a pair of the card holes 51 is parallel to or intersects with the connecting straight line between another pair of the card holes 51, and the angle of intersection between them can be 30°, 45°, 60° and 90°, etc. Preferably, the connecting straight line between a pair of the card holes 51 is perpendicular to the connecting straight line between another pair of the card holes 51; in this way, the connecting frame 1 can be installed in different orientations on the lamp body to suit installation in different environments.
[0031] As attached Figure 7 and attached Figure 8 As shown, the connecting frame 1 is provided with an angle adjustment mechanism for adjusting the angle of the lamp body 5. The angle adjustment mechanism is mainly used to adjust the light irradiation angle of the lamp body, and the angle adjustment mechanism is conventional prior art and will not be described in detail here.
[0032] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various equivalent changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
