Description

Technical field:

[0001] The utility model relates to the technical field of support frames, in particular to a convenient fish guard bracket. Background technology:

[0002] A support frame is a device used to support and fix equipment, and is commonly used in the fields of construction, machinery manufacturing, electronic equipment, etc. Its main function is to provide stable support force to ensure that the equipment or structure remains stable during use and prevents tipping or displacement. Support frames can have different shapes and structures according to specific uses and design requirements. Common ones include fixed support frames, adjustable support frames, and mobile support frames.

[0003] A cantilever support frame is a special type of support frame, which is characterized by having only one end fixed and the other end suspended, capable of bearing vertical loads and certain horizontal loads (e.g., a multifunctional cantilever support that can be rotated, lifted, and folded with Chinese patent application number 202123282320.5). Cantilever support frames are often used in situations where objects need to be suspended or supported without affecting the space below, such as cantilever cranes, cantilever structures, etc. As a common cantilever support frame, the turret is often used to fix fishing gear such as fishing rods and fish guards. For example, a stainless steel corner turret with Chinese patent application number 202322743202.2 is used. In the technical solution disclosed in the patent, the connection and fixation between the various parts are respectively connected and fixed by locking screws 6, height adjustment screws 7, anti-loosening screws 8, and direction adjustment screws 9. For example, the cantilever 3 and the base 5 are locked and fixed by direction adjustment screws 9. However, in this traditional connection method, it is often impossible to know in advance the torsion angle and number of turns when locking and fixing. The only way to determine whether it is locked is to twist until the screw cannot be turned. As far as this method is concerned, it is not only time-consuming and laborious to operate, but also the threads will be worn after long-term use, making it impossible to lock.

[0026] The utility model is further described below in conjunction with specific embodiments and drawings.

[0027] See Figures 1 to 9 As shown, a portable fish guard bracket comprises: a base 1, a gun barrel bracket 2 which is sleeved and mounted on the base 1 and can rotate and swing, and a locking device 3 for locking and adjusting the relative position of the gun barrel bracket 2 and the base 1, wherein the locking device 3 comprises a bolt rod 31 which passes through the connecting portion 21 of the gun barrel bracket 2 so that it can hold the base 1 tightly, a spline nut 32 which is mounted on the bolt rod 31 and is used to tighten the connecting portion 21, and a handle 33 which is sleeved and mounted on the spline nut 32 and is used to drive it to rotate, wherein the inner hole of the spline nut 32 is threadably matched with the bolt rod 31, and the outer wall of the spline nut 32 is tooth-engaged with the handle 33. The locking nut of the bolt rod 31 is set as a spline nut 32, so that the handle 33 can be installed by matching with the healthy teeth. The spline nut 32 is adjusted to the pre-locking position in advance, and the handle 33 is installed on the spline nut 32 at a suitable angle. Therefore, the locking device 3 can be locked by only driving the spline nut 32 to rotate a specific angle by the handle 33. The locking device 3 can be loosened by swinging the handle 33 in the opposite direction, thereby realizing simple and fast locking and adjustment of the barrel bracket 2, without the need to repeatedly rotate the nut each time to complete locking and loosening. Not only the use efficiency of the locking device 3 is greatly improved, but also wear is reduced and the service life is increased.

[0028] One end of the bolt rod 31 is a hexagonal head, and is embedded and positioned in a slot 211 on one side of the connecting portion 21. The other end of the bolt rod 31 passes through the connecting portion 21. The spline nut 32 and the handle 33 are installed on the other end of the bolt rod 31 and are limited and positioned by the first thumb screw 34. The connecting portion 21 is an elastic clamping portion bent in a "U" shape. The bending portion of the "U"-shaped bending portion is provided with a first mounting hole 212 for sleeved on the stepped shaft portion 11 of the base 1. The bolt rod 31 passes through the other end of the "U"-shaped bending portion.

[0029] The other end of the bolt rod 31 is provided with a first threaded hole 311 matching the first thumb screw 34, and a gasket 35 is provided between the spline nut 32 and the other side wall of the connecting portion 21. The gasket 35 is provided between the contact surfaces of the spline nut 31 and the connecting portion 21 to make contact, and the gasket 35 can not only prevent loosening, but also reduce wear and increase service life.

[0030] The end of the stepped shaft portion 11 is provided with a second threaded hole 111 for mounting on a second thumb screw 12 to limit the connecting portion 21. The base 1 also includes a mounting panel 13, on which second mounting holes 131 located at four corners are provided. The stepped shaft portion 11 is located at the center of the mounting panel 13.

[0031] One end of the handle 33 is provided with a toothed hole 331 for sleeved on the spline nut 32, and the other end of the handle 33 is provided with a gripping portion 332 extending obliquely outward, and the flat surface on the gripping portion 332 is perpendicular to the cross section of the toothed hole 331. The handle 33 is also provided with a limit stroke block 333, and the side wall of the connecting portion 21 is provided with a limit stroke groove 213 that matches the limit stroke block 333. The limit stroke groove 213 can limit the swing range of the handle 33 to 90°, that is, after the limit stroke block 33 is locked in the limit stroke groove 213, the swing angle of the handle 3 is 90° during the process of the limit stroke block 33 moving from one end of the limit stroke groove 213 to the other end. A limit stroke block 333 and a limit stroke groove 213 are respectively provided on the handle 33 and the connecting part 21 to limit the swing of the handle 33, so that the handle 33 can only swing within a range of 90°. This can not only shorten the swing range of the handle 33 and improve the locking and loosening efficiency, but also avoid thread wear caused by excessive rotation, thereby ensuring the use efficiency and life of the locking device 3.

[0032] The barrel support 2 is provided with a locking bolt 4 for locking and fixing the supported member, and the locking bolt 4 includes a screw body 41, a push block 42 disposed on one side of the head of the screw body 41 and capable of sliding out, and a bayonet 43 disposed on the screw body 41 and used to limit the push block 42, and the force arm is increased by extending the push block 42 out of the screw body 41.

[0033] A push block 42 that can slide out is provided at the head of the screw body 41. When the screw body 41 needs to be twisted and rotated, the push block 42 is pushed out of the screw body 41, thereby increasing the length of the rotating force arm of the screw body 41, thereby achieving a labor-saving effect. Secondly, a bayonet 43 is used to pass through the head of the screw body 41 to limit the push block 42, so as to prevent the push block 42 from falling off the screw body 41 during use, and to avoid the screw body 41 and the push block 42 from being separated during transportation and use. In addition, the bayonet 43 is used for limiting, so that the push block 42 can be easily replaced, and the practicality can be increased by replacing the push blocks 42 of different lengths.

[0034] A spring 44 for increasing friction is provided between the push block 42 and the screw body 41. A positioning hole 422 for positioning and installing the spring 44 is provided on the push block 42. One end of the spring 44 is located in the positioning hole 422, and the other end of the spring 44 is pressed against the inner wall of the screw body 41. The spring 44 is provided on one side of the push block 42 to contact and press against the inner wall of the screw body 41, thereby increasing the friction of relative sliding between the push block 42 and the screw body 41, so that the push block 42 always maintains a constant force during the pushing and pulling process, and the spring 44 can maintain the length of the push block 42 extending out of the screw body 41, so as to prevent the push block 42 from retracting during the rotation of the screw body 41 and affecting the use.

[0035] The head of the screw body 41 is provided with a plurality of protrusions 411 for applying force, and the push block 42 is located at one of the protrusions 411. By evenly providing a plurality of protrusions 411 around the head of the screw body 41, when the screw body 41 is rotated by hand, the protrusions 411 can greatly increase the convenience of applying force, making it easier to rotate the screw body 41.

[0036] The push block 42 is T-shaped, one end of which is inserted into the screw body 41, and the other end of which can be attached to the outer wall of the screw body 41 and evenly spaced from the convex portion 411 and distributed on the periphery of the screw body 41. The portion of the push block 42 extending out of the screw body 41 protrudes upward from the upper end surface of the screw body 41. The end of the push block 42 is arranged to protrude from the upper end surface of the screw body 41, so that the user can easily push the push block 42 out when using it.

[0037] The head of the screw body 41 is provided with a slide slot hole 412 for the push block 42 to be telescopically inserted, and the head of the screw body 41 is also provided with a limit hole 413 perpendicular to the slide slot hole 412 and used to install the bayonet 43, and the limit hole 413 extends to communicate with the slide slot hole 412; one side of the push block 42 is provided with a travel groove 421 for the bayonet 43 to be inserted and relatively slidable. The bayonet 43 is a kimm screw, and the maximum sliding stroke of the end of the bayonet 43 in the travel groove 421 is 5mm.

[0038] In the locking bolt 4, the spring 44 is installed on the push block 42 and inserted into the slide slot hole 412 of the screw body 41 together with the push block 42. Then the bayonet 43 is inserted from the limiting hole 413 to press into the stroke slot 421 of the push block 42 to realize the assembly of the push block 42 and the screw body 41. The limit of the push block 42 by the bayonet 43 allows the push block 42 to adjust the length of the screw body 41 within 5mm, and the friction between the push block 42 and the screw body 41 can be increased by the spring 44, so that the push block 42 maintains constant force during the push-pull process and can stay stably in a suitable position to prevent the push block 42 from sliding when the screw body 41 is twisted. When in use, the threaded portion of the screw body 41 is twisted into the corresponding threaded hole, and the push block 42 is pushed out of the slide slot hole 412 of the screw body 41, thereby extending the force arm length of the twisting screw body 41, thereby relatively increasing the force of twisting the screw body 41, and achieving a labor-saving effect.

[0039] To sum up, when the utility model is used, the connection part 21 of the gun barrel support 2 is sleeved on the stepped shaft part 11 of the base 1, and then the second big head screw 12 is installed on the end of the stepped shaft part 11, and the connection part 21 is limited on the stepped shaft part 11; further, the bolt rod 31 of the locking device 3 is passed through the connection 21, and the gasket 35 and the spline nut 32 are sleeved and installed on the bolt rod 31 in sequence, and the spline nut 32 is adjusted to the pre-locking state (that is: the spline nut 32 is rotated 90° to tighten and lock the connection part 21, and the gun barrel support 2 can still swing relative to the base 1 at this time), and the handle 33 is adjusted to a suitable angle and then sleeved on the spline nut 32, so that the limit stroke block 33 is positioned in the limit stroke groove 213 and is located at the end. , and then install the first thumb screw 34 on the bolt rod 31 to limit the spline nut 32 and the handle 33; further, install the locking bolt 4 on the barrel bracket 2, and after the supported member is inserted into the sleeve portion 22 of the barrel bracket 2, the supported member is fixed to the barrel bracket 2 by the locking bolt 4, and then the barrel bracket 2 is adjusted to a suitable position by turning the handle 33 90° to hold and lock the connecting portion 21 on the stepped shaft portion 11, so that the barrel bracket 2 maintains this angle and is locked on the base 1; further, when the angle needs to be adjusted, by bending the handle 33 back to its original position, the barrel bracket 2 can adjust the angle position relative to the base 1 again, and then after it is adjusted to a suitable position, the handle 33 is bent to the locking position. By adjusting in this way, the relative rotation of the barrel bracket 2 and the base 1 can be locked and loosened only by turning the handle 33 back and forth 90°, which greatly improves the efficiency of the turret's use and adjustment. In addition, when the handle 33 cannot be locked, the first thumb screw 34 can be removed and the handle 33 can be removed from the spline nut 32. After tightening the spline nut 32 to a suitable position, the handle 33 and the first thumb screw 34 can be reinstalled in place, so that they can be locked and loosened by swinging the rotating rod handle 33 90° again.
