도 6은 본 발명의 잠금부를 나타낸 요부분해사시도로서, 받침틀(10)이 갖는 작동실(11)은 2개이상으로서, 각기 결합공의 내벽으로부터 걸림스프링(40)이 갖는 직경보다 깊게 요입형성되고 또 각 작동실(11)의 양측벽에는 폭이 좁은 개방부를 갖는 결합홈(16)(17)이 형성되며, 작동실(11) 상부에는 덮개(20)의 잠금해지를 위한 삽입홈(18)이 형성된다.Figure 6 is a partial exploded perspective view showing the locking portion of the present invention, the supporting chamber 10 has two or more operating chambers 11, each formed in the recess deeper than the diameter of the locking spring 40 from the inner wall of the coupling hole In addition, coupling grooves 16 and 17 having narrow openings are formed at both side walls of each operation chamber 11, and insertion grooves 18 for unlocking the lid 20 are formed on the operation chamber 11. Is formed.

또한 걸림스프링(40)은 압축스프링에 비해 탄성이 더욱 강한 인장스프링으로 제작되는 것으로서, 받침틀(10)이 갖는 각 작동실(11) 내에 후퇴거리를 갖고 여유있게 결합될 수 있는 직경과 길이를 갖는 것으로서, 별도의 지지스프링(50)을 통하여 작동실(11) 내에 연결설치된다.In addition, the locking spring 40 is made of a tension spring having a stronger elasticity than the compression spring, and has a diameter and a length that can be easily coupled with a retraction distance in each operating chamber 11 of the support frame 10. As, it is connected to the operating chamber 11 through a separate support spring (50).

이러한 걸림스프링(40)의 연결설치시 이용되는 지지스프링(50)은 약간의 여유를 갖고 걸림스프링(40)을 관통할 수 있는 직경의 압축스프링으로 제작하여 걸림스프링(40)을 관통하여 압축된 상태에서 걸림스프링(40)과 함께 받침틀(10)이 갖는 작동실(11) 내에 진입시킨 다음 압축을 해제해 주게 되면 스프링의 복원과정에서 양단부가 결합홈(16)(17)에 결합되어 걸림스프링(40)을 연결지지하게 된다.The support spring 50 used in connection installation of the locking spring 40 is made of a compression spring having a diameter that can penetrate the locking spring 40 with a slight margin, and is compressed through the locking spring 40. After entering into the operating chamber 11 of the support frame 10 together with the locking spring 40 in the state to release the compression, both ends are coupled to the coupling grooves 16 and 17 in the restoring process of the spring. 40 will be connected and supported.

그리고 덮개(20)가 갖는 걸림편(21)은 닫힘시 각기 받침틀(10)측의 걸림스프링(40)이 마주하는 위치에 걸림스프링(40)의 최대돌출지점보다 약간 낮게 걸림 턱(25)이 형성되고 또 걸림턱(25) 상부에는 요입홈(26)이 형성되며, 상기 걸림턱(25) 아래에는 하방으로 갈수록 내측으로 경사진 안내면(27)이 형성되게 하여 걸림스프링(40)의 간섭에도 안내면(27)에 의한 안내로 덮개(20)의 닫힘이 원활하게 이루어지도록 함은 물론 덮개(20)의 완전한 닫힘시에는 그 걸림턱(25)이 걸림스프링(40)의 최대돌출부를 지나 그 하부측면과의 접촉으로 깊숙하고 강한 걸림이 이루어지도록 구성된다.In addition, the locking piece 21 of the cover 20 has a locking jaw 25 slightly lower than the maximum protruding point of the locking spring 40 at a position where the locking springs 40 on the support frame 10 face each other when closed. And a concave groove 26 is formed in the upper part of the locking step 25, and a guide surface 27 inclined inward toward the lower part is formed below the locking step 25 to prevent interference of the locking spring 40. The cover 20 is smoothly closed by the guide surface 27, and when the cover 20 is completely closed, the locking jaw 25 passes through the maximum protrusion of the locking spring 40 and the lower portion thereof. In contact with the side is configured to make a deep and strong grip.

도 10은 본 발명의 다른 실시예를 나타낸 요부분해사시도로서, 받침틀(10)에 연결설치되는 걸림스프링(60)을 인장스프링이 아닌 압축스프링으로 제작하되 양단부에는 결합부(62) (64)가 연장형성되게 하여 걸림스프링(60)을 압축시켜서 받침틀(10)이 갖는 작동실(11) 내에 진입시킨 다음 압축력을 해제해 주게 되면 복원과정에서 양측의 결합부(62)(64)가 작동실(11) 양측벽에 갖는 결합홈(16)(17) 내에 진입하여 연결상태를 유지하도록 할 수도 있음을 보여주고 있다.10 is a partial exploded perspective view showing another embodiment of the present invention, the engaging spring (60) connected to the support frame 10 is made of a compression spring, not a tension spring, but both ends 62 (64) Compression spring 60 is compressed to enter the operating chamber 11 of the support frame 10, and then releases the compressive force. Then, the coupling parts 62 and 64 of both sides are operated in the restoration chamber. 11) It is shown that the coupling grooves 16 and 17 which are provided at both side walls may be kept in a connected state.

이와 같이 걸림스프링(60)을 압축스프링으로 제작하여 양단부에 결합부를 갖도록 할 경우 지지스프링을 필요치 않아 구조를 더욱 간단히 할 수가 있는 반면 걸림스프링(60)을 인장스프링으로 제작하는데 비해 탄성강도가 떨어지고 또 강제압축을 통한 설치작업이 매우 까다로운 단점이 있으나, 목적하는바 달성할 수가 있게 되므로 본 발명은 걸림스프링이 받침틀이 갖는 작동실 내에 후퇴거리를 갖고 그 일부가 내벽으로부터 돌출하도록 탄력설치되게 하여 덮개의 닫힘시 덮개가 갖는 각 걸림편과 걸림이 이루어지도록 한 것이면 모두 만족한다.In this way, when the engaging spring 60 is manufactured as a compression spring to have a coupling part at both ends, the support spring is not required, so that the structure can be simplified, while the elastic spring is lowered as compared with when the locking spring 60 is manufactured as a tension spring. The installation work through forced compression has a very difficult disadvantage, but because the present invention can achieve the desired purpose, the present invention has a retraction distance in the operating chamber of the support frame, and a part thereof is elastically installed to protrude from the inner wall. When the closing, each of the engaging pieces and the locking is made to satisfy all.

도 7 내지 도 9는 덮개의 단계적인 닫힘시를 보여주고 있다.7 to 9 show the stepwise closure of the lid.

도 7은 덮개의 닫힘전을 나타낸 것으로서, 덮개(20)의 닫힘전 받침틀(10)측의 걸림스프링(40)은 각기 그 내부를 관통하는 지지스프링(50)에 연결지지되어 외측방향으로 충분한 후퇴거리가 확보된 상태에서 그 일부가 결합공(12)의 내벽으로부터 내측으로 일부돌출해 있게 된다.7 is a view illustrating the closing of the lid, and before the closing of the lid 20, the catching spring 40 on the side of the support frame 10 is connected to the supporting spring 50, which penetrates the inside thereof, respectively, so as to fully retreat in the outward direction. In the state where the distance is secured, a part thereof protrudes inward from the inner wall of the coupling hole 12.

도 8은 덮개의 닫힘중을 나타낸 것으로서, 덮개(20)의 닫힘으로 상기 덮개(20)가 받침틀(10)의 결합공(12) 내부로 진입하게 되면, 받침틀(10)의 결합공(12) 내벽으로부터 일부돌출되어 있던 걸림스프링(40)은 덮개(20)의 닫힘시 주어지는 자중 및 외력에 의해 덮개(20)가 갖는 각 걸림편(21)의 경사진 안내면(27)에 안내되어 외측방향으로 점차 후퇴하게 되므로 덮개(20)의 닫힘이 용이하게 이루어지게 된다.8 shows the closing of the cover, when the cover 20 is entered into the coupling hole 12 of the support frame 10 by the closing of the cover 20, the coupling hole 12 of the support frame 10 The catching spring 40 partially protruded from the inner wall is guided to the inclined guide surface 27 of each catching piece 21 of the cover 20 by the weight and the external force given when the cover 20 is closed, and moves outward. Since the retreat gradually, the closing of the cover 20 is easily performed.

도 9는 덮개의 닫힘후를 나타낸 것으로서, 덮개(20)가 받침틀(10)이 갖는 결합공(12)내에 완전히 진입하여 받침테(19)에 안착되면 덮개(20)의 각 걸림편(21)이 갖는 걸림턱(25)은 걸림스프링(40)의 최대돌출지점을 통과하여 걸림스프링(40)의 하부측면과 접촉하게 되고, 이때 걸림스프링(40)은 걸림편(21)의 큰 간섭영향권으로부터 벗어나 자체탄성 및 지지스프링(50)의 탄성으로 복원되어 걸림편(21)의 걸림턱(25) 상부에 갖는 요입홈(26) 내에 위치하게 되므로 걸림스프링(40)과 걸림편(21)은 걸림스프링(40)이 갖는 강한 탄성만큼 강한 걸림이 이루어져 잠금기능을 만족하게 된다.FIG. 9 shows the cover 20 after the cover is closed. When the cover 20 completely enters the coupling hole 12 of the support frame 10 and is seated on the support frame 19, the respective hook pieces 21 of the cover 20 are seated. The catching jaw 25 has a passage through the maximum protruding point of the catching spring 40 to contact the lower side of the catching spring 40, at which time the catching spring 40 is from the greater interference impact zone of the catching piece 21 Since the elasticity of the self-elasticity and the support spring (50) is restored and positioned in the recessed groove (26) having the upper part of the locking step (25) of the locking piece (21), the locking spring (40) and the locking piece (21) are locked. The locking is made as strong as the strong elasticity of the spring 40 is satisfied.

즉 덮개(20)는 힌지(30)를 축으로 한 닫힘시 덮개(20)의 각 걸림편(21)이 갖는 경사진 안내면(27)의 안내로 강한 탄성을 갖는 걸림스프링(40)이 쉽게 후퇴하게 되므로 별도의 조작없이 덮개(20)에 적절한 힘을 가해주는 것으로 완전한 닫힘이 이루어지게 되고, 이러한 덮개(20)의 완전한 닫힘시에는 받침틀(10)이 갖는 강한 탄성의 걸림스프링(40)과 덮개(20)가 갖는 걸림편(21)의 완전한 걸림으로 강한 잠금이 이루어지게 된다.That is, the cover 20 is easily retracted by the locking spring 40 having a strong elasticity as a guide of the inclined guide surface 27 of each locking piece 21 of the cover 20 when the hinge 30 is closed. Therefore, a complete closing is achieved by applying an appropriate force to the cover 20 without additional manipulation, and when the cover 20 is completely closed, a strong elastic locking spring 40 and the cover of the support frame 10 are provided. Strong locking is achieved by the complete locking of the locking piece 21 that 20 has.
