Description

Technical Field

[0001] The present invention belongs to the technical field of industrial endoscope equipment, and more specifically, relates to a quick plug-and-play design for an endoscope probe module. Background Art

[0002] An endoscope is a common non-destructive testing device and is widely used in the medical and industrial fields. In the existing endoscope equipment, when removing the probe module, the push blocks on both sides of the mounting bracket on the probe module are used to unlock it and then remove it. During this process, the downward unlocking direction of the two push blocks on the probe module is perpendicular to the direction in which the entire probe slides out, making it difficult for a single person to remove the probe; and the distance between the two push blocks is generally about 10 cm, making it strenuous to unlock with one hand. Therefore, in view of this situation, the present invention ingeniously proposes a quick plug-and-play design for an endoscope probe module to solve the deficiencies in the above technical background. Summary of the Invention

[0003] The present invention aims to solve the problem that it is relatively difficult to remove the probe module of the existing endoscope equipment with one hand.

[0004] The purpose and effect of a quick plug-and-play design for an endoscope probe module of the present invention are achieved by the following specific technical means: A quick plug-and-play design for an endoscope probe module includes a probe locking member fixed on the endoscope main body. A probe module is detachably connected to the probe locking member. The probe module includes a module housing. The module housing is slidably connected to the probe locking member. A lock buckle mounting bracket is fixedly connected to the upper side of the module housing. A sleeve bracket is fixedly connected to the center of the lock buckle mounting bracket. A sleeve is fixedly connected to the upper side of the sleeve bracket. A resetable unlocking pull ring part is movably sleeved outside the sleeve. A retaining ring is fixedly connected to the upper end of the sleeve. A lock tongue hole is provided on the upper side of the probe locking member on one side close to the lock buckle mounting bracket. A resetable lock tongue is slidably connected to the corresponding position on the lock buckle mounting bracket with respect to the lock tongue hole. A lever is fixedly connected to the side of the unlocking pull ring part. The lock tongue includes long parts on both sides and a short part in the middle. The short part in the middle is a connecting part. The long parts of the lock tongue are clamped in the lock tongue hole. The connecting part of the lock tongue is in contact with the lever. When the lever moves, it squeezes the connecting part to move inward into the lock buckle mounting bracket. The unlocking pull ring part includes an upper pull ring part, a middle pull ring part, and a lower pull ring part. The upper pull ring part is movably sleeved outside the sleeve. The middle pull ring part is movably sleeved under the upper pull ring part. A lever is fixedly connected to the side of the middle pull ring part. A lower pull ring part is also fixedly connected to the lower end of the upper pull ring part. Arc-shaped pieces are fixedly connected to both sides of the lower pull ring part. Limit blocks are provided at both sides of the lower pull ring part on the lock buckle mounting bracket. The limit blocks are set in a hook shape to hook and limit the arc-shaped pieces. A pull ring return spring is fixedly connected between the retaining ring and the upper pull ring part.

[0005] Furthermore, probe guide grooves are fixedly connected to both sides of the probe locking member, and probe guide strips are fixedly connected to both sides of the probe module. The probe guide strips are slidably connected in the probe guide grooves.

[0006] Furthermore, one side of the long part of the locking tongue close to the locking tongue hole is provided with an inclined surface, and the upper side of the probe locking part is provided with an arc surface. During the downward sliding of the module housing on the probe locking part, the inclined surface on the locking tongue touches the arc surface on the probe locking part.

[0007] Furthermore, the side of the connecting part of the locking tongue is provided with an inclined surface, the lever is in the shape of an inverted hook, and the inverted hook part of the lever is also provided with an inclined surface. The inclined surface on the connecting part is in contact with the inclined surface on the lever.

[0008] Furthermore, the inclination angles of the inclined surfaces on the connecting part and the lever are both set to 45°.

[0009] Furthermore, two guide posts are fixedly connected to the other end of the locking tongue different from the inclined surface. A locking tongue return spring is sleeved on the guide posts. The locking tongue return spring is arranged between the locking tongue and the lock buckle mounting bracket. Two limit holes are provided on the lock buckle mounting bracket, and the locking tongue return spring is placed in the limit holes.

[0010] Furthermore, top block chutes are provided on both sides of the lower pull ring part on the upper side of the lock buckle mounting bracket. Top blocks are slidably connected in the top block chutes, and the top block chutes are communicated with the limit holes. Movable blocks are slidably connected in the limit holes, and the movable blocks and the guide posts are located on both sides of the locking tongue return spring. A bayonet is provided on the side of the top block, and the end of the movable block is clamped in the bayonet, and the contact surfaces between the movable block and the bayonet are both provided with inclined surfaces. A limit block is fixedly connected to the upper end of the top block, and the distance from the extending part of one end of the arc-shaped piece to the other end to the center of the circle of the lower pull ring part gradually increases.

[0011] Furthermore, a number of connection holes are fixedly connected to the retaining ring in a circumferentially uniform distribution. A number of threaded holes corresponding to the connection holes are provided at the top of the sleeve. A number of fixing screws on the retaining ring penetrate through the corresponding connection holes and are threadedly connected to the corresponding threaded holes.

[0012] Furthermore, at least one circular ring piece is fixedly connected to the sides of the upper pull ring part and the middle pull ring part.

[0013] The beneficial effects of the present invention are as follows: 1. The present invention provides a quick plug-and-play design for an endoscope probe module. By cleverly setting two 45° inclined surfaces, the linear motion is transmitted and reversed into a 90° motion, making the unlocking direction the same as the direction in which the probe module slides out from the probe locking part, and coaxial centering the unlocking pull ring part and the probe wire outlet. After unlocking, the probe module can be easily pulled out. After changing the unlocking direction to be the same as the sliding-out direction of the probe module, the operation of a single person to take out the probe module is simple and fast; at the same time, coaxial centering the unlocking pull ring part and the probe wire outlet hole makes the pulling force concentrated in the axial direction, and the probe is evenly stressed during insertion and extraction, and will not be skewed, blocked or even stuck.

[0014] 2. The present invention provides a quick plug - and - unplug design for an endoscope probe module. By setting the limit block in a hook shape to restrict the longitudinal displacement of the unlocking pull - ring part, and using a pull - ring return spring to give the upper pull - ring part a lateral torsional force, when the probe module is disassembled from the probe locking part, it is necessary to first twist the upper pull - ring part to separate the arc - shaped piece from the limit block, and then lift the entire unlocking pull - ring part upward to complete the disassembly of the probe module. This can avoid accidentally touching the unlocking pull - ring and easily disassembling the probe module.

[0015] 3. The present invention provides a quick plug - and - unplug design for an endoscope probe module. When the upper pull - ring part and the lower pull - ring part rotate under the torsional force of the pull - ring return spring, driving the arc - shaped piece to rotate and be hooked by the limit block, due to the shape setting of the arc - shaped piece, it pushes the top block to move in the top - block sliding groove, and then squeezes the movable block to move, so that the movable block squeezes the compression lock - tongue return spring, which can provide a greater elastic force for the lock tongue, making the connection between the probe module and the probe locking part more stable.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] As attached Figure 1 To Attachment Figure 6 As shown, a quick plug-in design of an endoscope probe module includes a probe locking piece 3 fixed on the endoscope body, and the probe module is detachably connected to the probe locking piece 3; specifically, the probe module includes a module housing 1, and the module housing 1 is vertically slidably connected to the probe locking piece 3, and a lock mounting bracket 2 is fixedly connected to the upper side of the module housing 1, and a sleeve bracket 7 is fixedly connected to the center of the lock mounting bracket 2. Specifically, the sleeve bracket 7 passes through the center hole of the lock mounting bracket 2 and is fixedly connected therein with screws. ; A sleeve 8 is fixedly connected to the upper side of the sleeve bracket 7, specifically, the sleeve 8 is threadedly connected to the sleeve bracket 7; a resettable unlocking pull ring portion 6 is movably sleeved on the outer side of the sleeve 8, a retaining ring 10 is fixedly connected to the upper end of the sleeve 8, a lock tongue hole 301 is provided on the upper side of the probe locking member 3 near the side of the lock buckle mounting bracket 2, and a resettable lock tongue 15 is slidably connected to a position corresponding to the lock tongue hole 301 on the lock buckle mounting bracket 2; a lever 14 is fixedly connected to the side of the unlocking pull ring portion 6, the lever 14 is in the shape of a barb, and the lock tongue 15 includes long and short ends on both sides. The short part in the middle is the connecting part 11, the long part of the locking tongue 15 is clamped in the locking tongue hole 301, and the connecting part 11 of the locking tongue 15 is connected to the lever 14; the assembled probe module is slidably connected to the probe locking member 3. During this process, the locking tongue 15 touches the probe locking member 3 and is squeezed and moved to shrink into the lock mounting bracket 2. When the locking tongue 15 reaches the locking tongue hole 301, the locking tongue 15 pops out and is clamped into the locking tongue hole 301, thereby locking the probe module in the probe locking member 3. When the probe needs to be removed, the probe locking piece 3 is held stationary by one hand, and the unlocking pull ring portion 6 is held with the other hand to pull it to move, so that the lever 14 connected thereto squeezes the connecting block to move it, thereby driving the locking tongue 15 to disengage from the locking tongue hole 301, thereby releasing the lock between the probe module and the probe locking piece 3, and then continuing to pull the unlocking pull ring portion 6 until the probe module is removed from the probe locking piece 3; by providing the unlocking pull ring portion 6, it is convenient for the user to take out the probe module with one hand, which is simple and quick.

[0025] Among them, Figures 1 to 6As shown, the unlocking pull ring part 6 includes an upper pull ring part 19, a middle pull ring part 20 and a lower pull ring part 21. The upper pull ring part 19 is movably sleeved outside the sleeve 8. The middle pull ring part 20 is movably sleeved under the upper pull ring part 19. A shift lever 14 is fixedly connected to the side of the middle pull ring part 20. The lower pull ring part 21 is also fixedly connected to the lower end of the upper pull ring part 19 with screws. The upper pull ring part 19 and the lower pull ring part 21 clamp the middle pull ring part 20 in the middle, and the middle pull ring part 20 can rotate with the upper pull ring part 19; Arc-shaped pieces 22 are also fixedly connected to both sides of the lower pull ring part 21. Limit blocks 26 are provided at both positions on the lock catch mounting bracket 2 on both sides of the lower pull ring part 21. The limit blocks 26 are set in a hook shape, and the limit blocks 26 are arranged corresponding to the arc-shaped pieces 22. By hooking the arc-shaped pieces 22 with the limit pieces, the upward movement of the lower pull ring part 21 can be restricted, and thus the upward movement of the entire unlocking pull ring part 6 can be restricted; A pull ring return spring 9 is fixedly connected between the retaining ring 10 and the upper pull ring part 19. The pull ring return spring 9 gives the upper pull ring part 19 a longitudinal reset elastic force and a torsional force for lateral rotation. In the initial state, the arc-shaped piece 22 on the side of the lower pull ring part 21 is hooked by the limit block 26, and the entire unlocking pull ring part 6 cannot move longitudinally, thus avoiding the unlocking pull ring part 6 being accidentally touched to release the lock between the probe module and the probe locking part 3. When the probe module needs to be removed, the upper pull ring part 19 needs to be rotated first, and then the lower pull ring part 21 is driven to rotate, so that the arc-shaped pieces 22 on both sides thereof are disengaged from the limit blocks 26. At this time, the limit blocks 26 cannot restrict the lower pull ring part 21, and then the upper pull ring part 19 can be moved longitudinally to drive the entire unlocking pull ring part 6 to move to release the lock between the probe module and the probe locking part 3.

[0026] Among them, as Figure 1 shown, probe guide grooves 5 are fixedly connected to both sides of the probe locking part 3. The probe guide grooves 5 can be integrally connected to the probe locking part 3. Probe guide bars 4 are fixedly connected to both sides of the probe module. The probe guide bars 4 can be integrally connected to the probe module; The probe guide bars 4 are slidably connected in the probe guide grooves 5. The module housing 1 is slidably connected to the probe locking part 3 through the cooperation of the probe guide bars 4 and the probe guide grooves 5.

[0027] Among them, as Figures 2 to 3 shown, the long part of the lock tongue 15 is set as an inclined surface near the lock tongue hole 301. The upper side of the probe locking part 3 is set as an arc surface. During the downward sliding of the module housing 1 on the probe locking part 3, the inclined surface on the lock tongue 15 touches the arc surface on the probe locking part 3. Through the setting of the inclined surface and the arc surface, when the lock tongue 15 is squeezed by the probe locking part 3, it can slide and contract into the lock catch mounting bracket 2 more smoothly.

[0028] Among them, as Figures 1 to 6As shown, the side of the connecting portion 11 of the locking tongue 15 is set as an inclined surface, and the barb portion of the lever 14 is also set as an inclined surface. The inclination angles of both inclined surfaces are set to 45°. In the initial state, the inclined surface on the connecting portion 11 is in contact with the inclined surface on the lever 14. When the unlocking pull ring portion 6 is moved upward, the inclined surface on the lever 14 is driven to squeeze the inclined surface on the connecting portion 11. The connecting portion 11 is stressed to drive the locking tongue 15 to move and contract into the lock buckle mounting bracket 2. At this time, the locking tongue 15 disengages from the locking tongue hole 301.

[0029] Among them, as Figures 1 to 4 shown, two guide posts 12 are fixedly connected to the other end of the locking tongue 15 different from the inclined surface. A locking tongue return spring 13 is sleeved on the guide posts 12. The locking tongue return spring 13 is arranged between the locking tongue 15 and the lock buckle mounting bracket 2. Specifically, two limit holes 24 are provided on the lock buckle mounting bracket 2, and the locking tongue return spring 13 is placed in the limit holes 24. The setting of the guide posts 12 makes the connection between the locking tongue 15 and the locking tongue return spring 13 more stable.

[0030] Among them, as Figures 3 to 6 shown, top block chutes 23 are provided at both positions on the upper side of the lock buckle mounting bracket 2 on both sides of the lower pull ring portion 21. Top blocks 25 are slidably connected in the top block chutes 23, and the top block chutes 23 communicate with the limit holes 24. Movable blocks 27 are slidably connected in the limit holes 24, and the movable blocks 27 and the guide posts 12 are located on both sides of the locking tongue return spring 13. A bayonet 251 is provided on the side of the top block 25, and the end of the movable block 27 is clamped in the bayonet 251. The contact surfaces between the movable block 27 and the bayonet 251 are all set as inclined surfaces. A limit block 26 is fixedly connected to the upper end of the top block 25. Specifically, the limit block 26 is integrally connected with the top block 25. The distance from the extending part of one end of the arc-shaped piece 22 to the other end to the center of the lower pull ring portion 21 gradually increases; the pull ring return spring 9 provides a lateral torsional force for the upper pull ring portion 19 and the lower pull ring portion 21. When the probe module needs to be installed on the probe locking member 3, first rotate the upper pull ring portion 19 to rotate it to a predetermined position, and then slide the probe module downward on the probe locking member 3 along the probe guide groove 5. During this process, the arc-shaped piece 22 will not collide with the limit block 26, and their lateral positions are staggered. After the locking tongue 15 on the probe module pops out and is inserted into the locking tongue hole 301, release the upper pull ring portion 19. At this time, the upper pull ring portion 19 and the lower pull ring portion 21 are rotated by the torsional force of the pull ring return spring 9, thereby driving the arc-shaped piece 22 to rotate and be hooked by the limit block 26. At the same time, due to the shape setting of the arc-shaped piece 22, it causes the top block 25 to move in the top block chute 23, thereby squeezing the movable block 27 to move, so that the movable block 27 squeezes and compresses the locking tongue return spring 13, thereby providing a greater elastic force for the locking tongue 15 and making the connection between the probe module and the probe locking member 3 more stable.

[0031] Among them, as Figures 1 to 6As shown, a plurality of connection holes 16 are fixedly connected to the retaining ring 10 in a circumferentially uniform distribution. A plurality of threaded holes 17 corresponding to the connection holes 16 are provided at the top of the sleeve 8. A plurality of fixing screws 18 pass through the corresponding connection holes 16 on the retaining ring 10 and are threadedly connected to the corresponding threaded holes 17, thereby fixedly connecting the retaining ring 10 to the sleeve 8. Through the circumferentially uniformly distributed connection holes 16 and threaded holes 17, the retaining ring 10 can still be fixedly connected to the sleeve 8 by the fixing screws 18 after rotating a certain angle when being disassembled from the sleeve 8. By the above method, the torque formed by the pull ring return spring 9 can be further adjusted. When the tongue return spring 13 has insufficient elasticity after being used for a long time, by increasing the torque of the pull ring return spring 9, the movable block 27 is squeezed to compress the tongue return spring 13, providing sufficient elasticity for the tongue 15, and avoiding the unstable connection between the probe module and the probe locking member 3 after long-term use.

[0032] Among them, as Figure 6 shown, at least one circular ring piece 28 is fixedly connected to the side edges of the upper pull ring portion 19 and the middle pull ring portion 20. Specifically, the circular ring piece 28 is integrally connected to the upper pull ring portion 19 or the middle pull ring portion 20. By providing a plurality of circular ring pieces 28, it is convenient for the user to apply a pulling force to the entire unlocking pull ring portion 6, thereby facilitating the removal of the probe module from the probe locking member 3.
