Description
Technical Field
The utility model relates to the technical field of furniture manufacturing, in particular to a dovetail groove locking device.
Background
At present, the flat plate, the cross beam or other parts of household furniture, kitchen furniture, office appliances, quick buildings and movable guardrails all adopt a detachable structure, and the detachable structure can save packaging space, is convenient to transport and saves freight. In the prior art, various plates are connected by external forces such as screws, hinges, glue, metal connecting pieces, buckling pieces and the like, however, after the plates are assembled, the plates are easy to deform or scatter due to the fact that the mutual connection among the parts is not firm when the plates are integrally moved, so that troubles are caused to a user, and potential safety hazards exist. Therefore, it is necessary to secure the locking at the interconnection between the parts to prevent accidents.
Therefore, we propose a new connection structure to solve the above-mentioned problems.
Disclosure of Invention
The utility model aims at overcoming the defects of the prior art, and provides a dovetail groove locking device, which comprises the following specific scheme:
the dovetail groove locking device comprises a first component and a second component which are installed in a matched mode, wherein a dovetail groove is formed in the first component, and a limit sliding block is arranged in the dovetail groove in a sliding mode; the middle part of the limit sliding block is provided with a travel hole, the limit sliding block is also provided with a pair of through holes which extend to the left side and the right side of the limit sliding block respectively corresponding to the travel hole, a inserted link is arranged in the through holes in a sliding manner, the inserted link is provided with a limit plate, the periphery of the through hole is provided with a travel groove aiming at the limit plate, the inserted link is sleeved with a tension spring which applies tension to the limit plate, and the tension spring forces the limit plate to approach to the travel hole; the side wall of the dovetail groove is provided with two positioning holes which respectively correspond to the through holes; the first component is in threaded connection with a fastening bolt, a conical pushing head is arranged at the bottom end of the fastening bolt, and the pushing head is used for pushing the two inserting rods to two sides of the limiting sliding block respectively.
Based on the above, one end of the inserted link, which is close to the positioning hole, is conical, and one end of the inserted link, which is close to the travel hole, is provided with an inclined surface adapted to the thrust head.
Based on the above, the edge profile of the limiting plate is square.
Compared with the prior art, the utility model has substantial characteristics and progress, and particularly has the following advantages:
the dovetail groove locking device provided by the utility model is convenient for quickly disassembling and assembling two parts, and can ensure firm connection between the parts, and the structural design is ingenious and practical.
Drawings
Fig. 1 is a schematic view of the overall structure of the present utility model.
Fig. 2 is a side view of a matching structure of a limiting plate and a plunger in the present utility model.
In the figure: 1. a first component; 1-1, positioning holes; 2. a limit sliding block; 2-1, penetrating holes; 2-2, a stroke groove; 2-3, a stroke hole; 3. a second component; 4. a rod; 5. a limiting plate; 6. a tension spring; 7. and (5) fastening a bolt.
Detailed Description
The technical scheme of the utility model is further described in detail through the following specific embodiments.
Examples
As shown in fig. 1-2, the utility model provides a dovetail groove locking device, which comprises a first component 1 and a second component 3 which are installed in a matching way, wherein a dovetail groove is formed in the first component 1, and a limit sliding block 2 is arranged in the dovetail groove in a sliding way; the middle part of the limit sliding block 2 is provided with a travel hole 2-3, the limit sliding block 2 is also provided with a pair of through holes 2-1 which extend towards the left side and the right side of the limit sliding block 2 respectively, the through holes 2-1 are internally provided with a plug rod 4, the plug rod 4 is provided with a limit plate 5, the periphery of the through holes 2-1 is provided with a travel groove 2-2 aiming at the limit plate 5, the plug rod 4 is sleeved with a tension spring 6 which applies tension to the limit plate 5, and the tension spring 6 forces the limit plate 5 to approach to the position close to the travel hole 2-3; the side wall of the dovetail groove is provided with two positioning holes 1-1 which respectively correspond to the through holes 2-1; the first component 1 is in threaded connection with a fastening bolt 7, a conical pushing head is arranged at the bottom end of the fastening bolt 7 and used for pushing the two inserting rods 4 to two sides of the limiting sliding block 2 respectively.
In order to facilitate the insertion of the inserted link 4 into the positioning hole 1-1, one end of the inserted link 4 close to the positioning hole 1-1 is conical; in addition, when the bottom end of the fastening bolt 7 moves downwards, in order to facilitate pushing the insert rod 4 to move, an inclined surface matched with the pushing head is arranged at one end of the insert rod 4 close to the travel hole 2-3.
